Description

Circuit control system, series control device and control method thereof

Technical Field

The invention relates to the field of circuit control, in particular to a circuit control system, a series control device and a control method thereof, which are particularly suitable for controlling lamps.

Background

In the existing circuit control field, such as the lamp control field, a passive wireless control mode is increasingly widely applied.

Taking lamp control as an example, the existing passive wireless control device generally comprises a remote controller and a lamp control switch, and in the working process, the remote controller sends a signal to the lamp controller to control the lamp to work. Both the remote control and the luminaire controller need to be individually powered to maintain operation.

The power supply modes of the remote controller are mainly two, one is a battery power supply mode, and the other is a self-generating power supply mode. The lamp controller is powered by two modes, one is directly connected in parallel in a circuit, such as between a zero line and a live line, and directly obtains electric energy from the circuit, and the other is connected in series in the circuit of lamp operation and obtains electric energy from the circuit of lamp operation.

Because of the respective electric energy acquisition modes and the working characteristics of the remote controller and the lamp controller, certain coordination relations are formed between the remote controller and the lamp controller. For example, the remote controller powered by the battery can continuously provide more electric energy when sending signals, and the remote controller in a self-generating mode can collect the energy when pressing to convert the energy into electric energy, but the electric energy obtained at one time is less, so that the signal sending time is short.

Correspondingly, the parallel lamp controller continuously acquires electric energy from the circuit, does not influence the work of the lamp, can receive pulse signals with short existence time, and can be matched with the remote controller in a self-generating mode. However, the lamp controller in the parallel connection mode is continuously in a working state with higher power, more electric energy is consumed, more importantly, zero line and live line are required to be simultaneously supplied, so that when only a single live line exists in a lamp circuit in a building, the zero line is required to be rewired and installed, the engineering quantity is larger, and the lamp controller is relatively complicated.

The lamp controller is connected in series in a working loop of the lamp, working electric energy is required to be obtained from the loop, if the lamp controller is in a standby state continuously, the working loop of the lamp is required to continuously provide working current of the lamp controller, and the working power of the lamp controller is high, so that the lamp can continuously pass through the large working current, the lamp emits light slightly or flashes, the use experience of a user on the lamp is affected, and the service life of the lamp is reduced. In order to avoid such a situation, the existing serial lamp controller generally sets a dormant working mode, that is, sets the working time and the dormant time to be in different powers, for example, sets the ratio of the working time to the dormant time to be 1:100, so that the power consumption of the lamp controller in the dormant state is lower, and the current is smaller, and therefore the lamp does not lighten or flicker during dormancy. However, there is a problem in that a control signal of a long time is required to wake up the lamp controller in such a sleep mode, that is, the length of the control signal is at least capable of maintaining the entire operation and sleep time, so that the lamp controller can be relatively accurately awakened and stably receive the control signal, that is, the remote controller needs to transmit a long code at a time, otherwise, a situation in which the lamp controller cannot be awakened, that is, the remote controller is not flexible in control, occurs. Therefore, for the serial or dormant lamp controller, the remote controller powered by the battery is required to work cooperatively, that is, the remote controller in a self-generating mode cannot work cooperatively with the lamp controller.

In addition, the series-connected sleep mode lamp controller needs to distinguish between the working and sleep states, the corresponding circuit is more complex, and there is a risk that the control signal cannot be received.

Referring to fig. 1 to 7, there is shown a circuit control system and a series control device 20 according to a first embodiment of the present invention. Fig. 1 is a block diagram schematic of a circuit control system according to a first embodiment of the present invention. Fig. 2 is a block diagram schematic diagram of a series control device according to a first embodiment of the present invention.

The circuit control system is used for being connected with a load circuit to control the operation of at least one load 100, and comprises a mobile control device 10 and a serial control device 20, wherein the mobile control device 10 can movably send control signals to the serial control device 20, and the serial control device 20 controls the operation of the load 100.

The load 100 is exemplified by, but not limited to, a lamp, an electric device, and the manner of controlling the operation of the load 100 is exemplified by, but not limited to, controlling the on-off of the operation current supplied to the load 100. Of course, in other embodiments of the invention, the circuit control system may also be controlled in other ways, such as controlling a specific operating state of the load 100. In some embodiments, the circuit control system is suitable for controlling a lamp, such as controlling the on/off of the lamp, or controlling the brightness/darkness of the lamp, or controlling the combined working mode of a plurality of lamps.

The series control device 20 is used to be connected in series to the circuit in which the load 100 operates, so as to directly obtain electric energy from the loop in which the load 100 operates to operate, and directly control the operation of the load 100.

The series control device 20 has two interfaces 201 for accessing the loop in which the load 100 operates, such as an input interface and an output interface. For example, when the operation loop of the load 100 is a two-phase circuit composed of a neutral wire and a live wire, the series control device 20 is connected in series to the neutral wire side. That is, the load 100 is connected across the neutral and hot wires, and the series control device 20 is connected in series between the neutral and the load 100. It should be noted that in the conventional parallel connection manner, the control device at one end of the lamp needs to be provided with a plurality of connectors, for example, 4 connectors, two connectors are used for connecting the power supply circuit to obtain the electric energy, and two interfaces 201 are used for connecting the load 100, so that the circuit is relatively complex, but in the present invention, at least 2 interfaces 201 are needed, so that the circuit can be conveniently connected, and the circuit is simpler. Of course, in other embodiments of the invention, more interfaces 201 may be provided, as the invention is not limited in this respect.

It should be noted that, the conventional wired switch is usually connected in series in the circuit in which the load 100 is operated, and when the line is arranged, it is usually necessary to reserve the line in the wall, that is, to provide the connection between the zero line of the wired switch and the load 100, and the serial control device 20 of the present invention needs to be connected in series in the circuit in which the load 100 is operated, so that the serial control device 20 can simply connect the serial control device 20 to the circuit in which the load is operated by using the interface 201 of the original wired switch, without separate wiring, thereby rapidly converting the wired control mode into the wireless control mode. In other words, the connection mode of the serial control device 20 is identical to that of the conventional wired switch, so that the conventional wired switch can be directly replaced, and the control mode can be changed without changing the original circuit.

Further, in some embodiments of the present invention, the mobile control device 10 is a self-generating wireless signal transmitting device that collects energy for operating the mobile control device 10 to convert it into electrical energy, thereby transmitting a control signal to the serial control device 20 via the electrical energy. That is, the circuit control system is operated to generate power to transmit a control signal to the series control device 20 during operation of the mobile control device 10, thereby controlling the operation of the load 100 through the series control device 20. In other words, the user can control the operation of the load 100 through the variable position of the mobile control device 10 within a predetermined range, i.e., free wireless control is realized, and the mobile control device 10 is a self-generating device, so that it is not necessary to install a battery, the trouble of replacing the battery is avoided, and electric power is saved.

More specifically, in some embodiments of the present invention, the movement control device 10 includes at least one key 11 and a generator 12, and when the key 11 is pressed, the generator 12 is driven to generate electric energy, i.e. the pressed energy is converted into electric energy for transmitting a control signal. The mobile control device 10 may be an electromagnetic self-generating wireless signal transmitting device. That is, the movement control device 10 can generate power by electromagnetic induction to transmit a control signal, and it should be understood by those skilled in the art that the power generation method of the movement control device 10 is not a method of the present invention. Preferably, the mobile power generation device of the present invention is a wireless signal transmission device that performs self-power generation by electromagnetic induction principle. In some embodiments of the present invention, when the time of the control signal sent by the mobile control device does not exceed 50ms, the serial control device 20 makes an immediate response, and controls the load 100 to work, so that the working state of the load 100 is not affected, for example, the phenomenon that the lamp flicker does not occur. The movement control device 10 comprises a communication unit 13 for communication control with the serial control device 20. Further, the generator 12 is electrically connected to the communication unit 13, and provides the communication unit 13 with operating electric energy. During operation, the key 11 is pressed to drive the generator 12 to generate electric energy, which is transmitted to the communication unit 13, so that the communication unit 13 works to send a control signal.

The serial control device 20 comprises a power taking control unit 21, a control switch 22, a switching power supply unit 24, a switch driving unit 25 and a non-sleep communication unit 23.

The power take-off control unit 21 selectively controls the passage path of the current so as to controllably supply the electric power. More specifically, the power taking control unit 21 selectively controls the power supply to the control switch 22, the non-sleep communication unit 23, or the switching power supply unit 24. The power taking control unit 21 is electrically connected to the control switch 22, the non-sleep communication unit 23, and the switching power supply unit 24. More specifically, the non-sleep communication unit 23 and the communication unit 13 of the mobile control apparatus 10 are configured to be communicatively connected.

In some embodiments of the present invention, the power taking control unit 21 selects paths through which the control current passes in a divided period, for example, selects paths through which two half periods controlled in one period are different.

The control switch 22 is used for controlling the power-taking control unit 21 to be connected with the load 100. When the series control device 20 is connected to the load 100 circuit, the control switch 22 is provided between the power taking control unit 21 and the load 100. When the load 100 needs to operate, the control switch 22 is closed, so that the current passing through the power taking control unit 21 is transmitted to the load 100 through the control switch 22 for the load 100 to operate. When the load 100 does not need to operate, the control switch 22 is turned off, i.e., the current passing through the power take-off control unit 21 cannot reach the load 100 through the control switch 22. In other words, the branch in which the control switch 22 is located provides the load 100 with an operating state of current, such as a current reaching rated power operation, when current reaches the load 100 through the control switch 22, the load 100 can operate normally, when current does not reach the load 100 through the control switch 22, the load 100 does not operate or the load 100 is in a state well below rated power. For example, but not limited to, the normal operation is not affected, that is, abnormal conditions that affect the use effect, such as sporadic, intermittent blinking, micro-lighting, etc., caused by unstable operation state of the control device, of the 3-10W low-power LED lamp are not caused.

The control switch 22 can be an electronically controlled switch module, such as a relay, and those skilled in the art will appreciate that the particular type of control switch 22 is not a limitation of the present invention. The control switch 22 has an open state and a closed state, and when the control switch 22 is in the closed state, the normal operation circuit of the load 100 is turned on, i.e., the load 100 is normally operated, and when the control switch 22 is in the open state, the normal operation circuit of the load 100 is turned off, i.e., the load 100 is not operated. Preferably, in some embodiments of the present invention, the initial state of the control switch 22 is an off state.

Referring to fig. 3, 5A, and 5B, the switching power supply unit 24 is used for adjusting the power passing through the switching power supply unit 24 by the power taking control unit 21, such as performing voltage and current adjustment. More specifically, the switching power supply unit 24 regulates the electric power reaching the load 100 and the non-sleep communication unit 23 by the power taking control unit 21 so that the electric current passing through the switching power supply unit 24 to both the load 100 and the non-sleep communication unit 23 is small, thereby making the load 100 not start operation such as a lamp not to flicker or emit light when the electric current passes only through the switching power supply unit 24 to the load 100, and making the non-sleep communication unit 23 continuously operate at a lower power. The switching power supply unit 24 is disposed at both sides of the control switch 22, and when the control switch 22 is turned on, the switching power supply unit 24 is powered off to stop the operation, and when the control switch 22 is turned off, the switching power supply unit 24 is operated. When the control switch 22 is closed or at the closing moment, the switch power supply unit 24 obtains the electric energy at the opening moment or the opening moment of the control switch 22, so that the non-sleep communication unit works 23. When the control switch 22 is closed, the switching power supply unit 24 is short-circuited, and current does not pass through the switching power supply unit 24, so that the switching power supply unit 24 does not operate.

When the series control device 20 is connected to the load 100 circuit, the control switch 22 electrically connects the power taking control unit 21 and the load 100 and the non-sleep communication unit 23. More specifically, the switching power supply unit 24 is provided on both sides of the control switch 22, that is, the current passing through the power taking control unit 21 can selectively pass through the control switch 22 and/or the switching power supply unit 24 to the load 100, thereby forming different closed operation loops.

When the control switch 22 is turned on or at the moment of turning on, the switching power supply unit 24 obtains the electric energy at the moment of turning off or turning off the control switch 22 to enable the non-sleep communication unit to work 23, and the electric energy obtained at the moment of the switching power supply unit 24 maintains the non-sleep communication unit 23 to work before the power-taking control unit 21 starts to supply power; when the control switch 22 is closed, the switching power supply unit 24 loses power and stops working, the current passing through the power-taking control unit 21 is transmitted to the load 100 through the control switch 22, so that the load 100 works normally, the non-sleep communication unit 23 directly obtains electric energy by the power-taking control unit 21 to maintain working, that is, the power-taking control unit 21 provides low-power working current for the non-sleep communication unit 23, that is, the non-sleep communication unit 23 continuously works with low power, and continuously receives control information sent by the mobile control device 10. When the control switch 22 is turned off, the current passing through the power taking control unit 21 is regulated by the current passing through the switching power supply unit 24 and then is sent to the non-sleep communication unit 23, and a part of the smaller current is sent to the load 100 to form a closed circuit, for example, a low-power closed circuit is formed between the neutral line and the live line, and the current in the circuit is mainly used for maintaining the non-sleep communication unit 23, so that the current passing through the load 100 is smaller, and therefore the load 100 is not caused to operate, such as a flickering and lighting condition of a lamp. Thus, the non-sleep communication unit 23 can obtain the operating power regardless of whether the load 100 is in an operating state or the load 100 is in a non-operating state, thereby continuously receiving the signal transmitted from the mobile control device 10, so that the mobile control device 10 is not required to transmit a long signal, and the serial control device 20 can accurately receive the signal transmitted from the mobile control device 10, so that the phenomenon of control confusion does not occur.

The switching power supply unit 24 is exemplified by, but not limited to, a switching power supply module, and of course, the switching power supply unit 24 can also enable other power supply regulating devices, for example, the switching power supply unit 24 is a step-down AC-DC converter, and the voltage output by the switching power supply unit ranges from 1.5V to 24V, for example.

The switch driving unit 25 is used for driving the control switch 22 to operate, for example, driving the control switch 22 to be closed or opened. Further, the switch driving unit 25 acquires a signal from the non-sleep communication unit 23 to drive the control switch 22 to operate. That is, the non-sleep communication unit 23 sends a control signal to the switch driving unit 25, and drives the control switch 22 to operate via the switch driving unit 25, thereby controlling the on-off of the operating current of the load 100, for example, controlling the on-off of the operating current from the power taking control unit 21 to the load 100 via the control switch 22, thereby realizing wireless control of the load 100.

Further, the switch driving unit 25 is supplied with the passing electric power by the switch power supply unit 24, that is, the switch power supply unit 24 supplies the switch driving unit 25 with the operating electric power in such a manner as to electrically connect the switch driving unit 25. In other words, the switch driving unit 25 is electrically connected to the non-sleep communication unit 23, the switching power supply unit 24, and the control switch 22, respectively. The switch drive unit 25 is by way of example but not limitation a relay drive module.

Further, referring to fig. 2 and 3, the power taking control unit 21 includes a first half-cycle control element 211, a second half-cycle control element 212, and a pulse width controller 213, where the first half-cycle control element 211 and the second half-cycle control element 212 selectively control currents of two opposite half-cycles, respectively. Preferably, the first half-cycle control element 211 and the second half-cycle control element 212 selectively control currents in opposite directions. For example, in one sinusoidal current cycle, the first half-cycle control element 211 selects to control the current of the positive half-cycle and the second half-cycle control element 212 selects to control the current of the negative half-cycle. That is, the current of the half cycle selectively passes through the first half cycle control element 211, and the current of the other half cycle selectively passes through the second half cycle control element 212. The pulse width controller 213 controls the second half-cycle control element 212 to be turned off at a predetermined interval and to draw power from the circuit to power the non-sleep communication unit 23. In some embodiments, the pulse width controller 213 controls the second half-cycle control element 212 to open a smaller interval at circuit zero crossings.

Further, when the series control device 20 is connected to the circuit of the load 100, the current passing through the selected half period of the power taking control unit 21 passes through the first half period control element 211, when the control switch 22 is closed, the half period current passes through the first half period control element 211 to reach the control switch 22, and is transmitted to the load 100 through the control switch 22 to normally operate, when the current enters the second half period, the pulse width controller 213 controls the second half period control element 212 to break a smaller voltage interval at the zero crossing point so as not to affect the normal operation of the load 100, and at the moment of breaking, the pulse width controller 213 obtains the electric energy in the circuit for the non-sleep communication unit 23 to operate. In particular, the power drawn by the pulse width controller 213 can support operation of the non-sleep communication unit 23 for multiple cycles. When the control switch 22 is turned off, half-cycle current reaches the switching power supply unit 24 through the first half-cycle control element 211, and is regulated by the switching power supply unit 24 to be respectively transmitted to the non-sleep communication unit 23 and the load 100, when the current enters the second half-cycle, the pulse width controller 213 controls the second half-cycle control element 212 to turn off a smaller voltage interval at the zero crossing point, and at the moment of the turn-off, the pulse width controller 213 takes the electric power in the circuit for the non-sleep communication unit 23 to operate.

That is, when the control switch 22 is turned off, the non-sleep communication unit 23 takes out the power for the low power operation by the switching power supply unit 24, at which time the load 100 is not operated, when the control switch 22 is turned on, the load 100 is operated, the switching power supply unit 24 is not operated, and the non-sleep communication unit 23 takes out the power by the pulse width controller 213, whereby the non-sleep communication unit 23 can continuously take out the power for the low power operation regardless of whether the load 100 is operated or not, and regardless of which half cycle the current in the circuit is in, i.e., the non-sleep communication unit 23 is continuously in the low power operation state without sleep.

Referring to fig. 6, a schematic diagram of the power take-off control principle of the serial control device according to the first embodiment of the present invention is shown. Taking one voltage cycle as an example, one voltage cycle is divided into two control sections, namely a first control section 2110 and a first second control section 2120, wherein the first control section 2110 corresponds to a section selected by the first half-cycle control element 211, the second control section 2120 corresponds to a section selected by the second half-cycle control element 212, and in the period controlled by the second half-cycle control element 212, the second half-cycle control element 211 is controlled to be disconnected at a zero crossing point 21200 of the first control section 2110 and the second control section 2120 to form a disconnection section 21201 in a predetermined section, and the rest section of the second control section 2110 is selected to pass, so that the pulse width empty controller 23 is powered at the disconnection section 21201. That is, the current in the first control section 2110 of one cycle is transmitted to the switching power supply unit 24 or the load 100 through the first half-cycle control element 211, the current in the second control section 2120 is transmitted to the switching power supply unit 24 or the load 100 through the second half-cycle control element 212, and the off section 21201 near the zero crossing point 21200 of the second control section 2120 turns off the current in the second half-cycle control element 212, so that the pulse width controller 213 takes the electric energy on both sides of the second half-cycle control element 212 in the off section 21201 for the non-sleep communication unit 23 to operate, thereby operating in a repeated cycle. In some embodiments, the pulse width controller 213 stores power for a plurality of cycles of operation of the non-dormant communication unit 23, i.e., after one cycle, the pulse width controller 213 continues to power the non-dormant communication unit 24 even if power is not provided.

The non-sleep communication unit 23 includes a communication module 231, a voltage stabilizing module 232, and a micro-processing control module 233, where the communication module 231 is used for being communicatively connected to the mobile control device 10, the voltage stabilizing module 232 is used for adjusting the power transmitted to the non-sleep communication module 231, and the micro-processing control module 233 is used for processing control signals and sending control information to the switch driving unit 25.

Further, the pulse width controller 213 is electrically connected to the voltage stabilizing module 232 so as to regulate the power transmitted by the pulse width controller 213 through the voltage stabilizing module 232. The switching power supply unit 24 is electrically connected to the voltage stabilizing module 232 so that the electric power transmitted by the switching power supply unit 24 is regulated by the voltage stabilizing module 232. That is, the power delivered to the non-sleep communication unit 23 through the pulse width controller 213 and the switching power supply unit 24 can be regulated by the voltage stabilizing module 232 to ensure a stable operation of the non-sleep communication unit 23 with low power.

In some embodiments of the present invention, the first half-cycle control element 211 can be implemented as a diode to select current through the positive half-cycle, and the second half-cycle control element 212 can be implemented as a MOS transistor to select current through the negative half-cycle. The pulse width controller 213 selects a zero crossing point in the circuit period to a predetermined voltage range to control the second half-cycle control element 212 to be turned off, and obtains electric energy by the instantaneous voltage difference between the two ends of the second half-cycle control element 212 for the non-sleep communication unit to work. By way of example, but not limitation, the pulse width power module draws electrical energy from the negative half-axis 0-18V. When the control switch 22 is in a closed state, when the alternating current is in a positive half cycle, the diode supplies power to the load 100, such as a lamp, then the positive half cycle is ended, the alternating current starts to change to a negative half cycle, the state of the MOS tube is disconnected from a zero crossing point to a preset voltage interval, such as an interval of 0-18V, and in the time when the MOS tube is disconnected, the pulse width electricity taking module obtains instant electric energy supply which can support the serial control device 20 to maintain for a plurality of periods; when the voltage of the ac power rises above a preset level (e.g., 18V), the MOS transistor is turned on, and the negative half-cycle power supply supplies power to the load 100, such as a lamp, because the MOS transistor is turned off for a very short time, the brightness of the lamp cannot be changed by visual inspection, so that the serial control device 20 continuously operates with low power while the load 100 operates.

It should be noted that, in this embodiment of the present invention, the voltage control range of the pulse width controller 213 is, for example, 0-18V, and it should be understood by those skilled in the art that the pulse width controller 213 specifically controls the off voltage range and is not a limitation of the present invention, and in other embodiments of the present invention, the voltage control range of the pulse width controller 213 may be other ranges, such as 0-15V, 0-16V, 0-17V, 0-18V, 0-19V, 0-20V, and 0-21V. Preferably, the power-on range of the pulse width controller 213 is 0-18V, and the series control device can continuously work in the power-on range, and meanwhile, the circuit in the circuit is small enough, so that the lamp does not flash.

Further, in some embodiments of the present invention, referring to fig. 7, the pulse width controller 213 is implemented as an operational amplifier, through which the second half-cycle control element 212 is controlled to be turned off at a predetermined interval. A, B are respectively arranged at two ends of the second half-cycle control element 212, the voltage of two ends A, B of the second half-cycle control element 212 is monitored through the operational amplifier, once the amplitude of the negative half-cycle alternating current voltage exceeds 18V (an example value), the operational amplifier immediately outputs a signal to enable the MOS tube to be conducted, so that the voltage difference between the two points A, B is zero, and the process is repeated in the next half-wave period, so that when the lamp is lighted, the switching time of the MOS tube is controlled through the operational amplifier, the electric energy required by the system is obtained at the two points A, B, and the serial control device 20 can also have the electric energy to maintain working when the lamp is lighted, namely, the control signal of the mobile control device 10 is continuously received.

Further, the non-sleep communication unit 23 and the switching power supply unit 24 select the module types matched with each other, so that the control circuit works with low power consumption as a whole. For example, in some embodiments, taking a 3W LED lamp as an example, the switching power supply unit 24 may use a high-efficiency device, for example, the switching power supply unit 24 may use a buck AC-DC converter, the output voltage range of the switching power supply unit 24 may be 1.5-24V, for example, the switching power supply unit 24 may be formed by a chip such as UCC28730 of LNK3203D, TI of PI company, to provide 3.3V DC power required by the communication module 231, and 12V DC power required by the control switch 22; the communication module 231 of the non-sleep communication unit 23 also selects a device with low ultra-power consumption, the communication module 231 of the non-sleep communication unit 23 may adopt a7129 of amicam corporation to implement a digital high-frequency signal transceiving function, when the power supply voltage VCC of the a7129 is actually measured to be reduced to 2V, the normal working current is 3.9mA, the micro-processing control module 233 adopts a low-power consumption device and performs intermittent working processing to reduce the power consumption of the micro-processing control module 233, and the standby current of the singlechip in the sleep state may be as low as about 10 uA. Thus, the total consumption current of the communication module 231 plus the micro-process control module 233 is within 4mA, and if the supply voltage is maintained at 2V, the power consumption is 4*2 =8 milliwatts; the voltage stabilizing module 232 adopts a high-efficiency DC-DC chip, and when the voltage supplied to the non-sleep communication unit 23 by the switching power supply unit 24 and/or the pulse width controller 213 fluctuates, the DC-DC chip of the voltage stabilizing module 232 can provide a stable working voltage to the communication module 231, so that the non-sleep communication unit 23 is continuously in a low-power working state for receiving control signals through combination of different schemes. It should be noted that the microprocessor control module 233 is intermittently operated in the non-sleep communication unit 23, so as to reduce the power consumption of the whole non-sleep communication module 231, but the communication module 231 is not sleep, i.e. continuously receives control signals, so that the control signals sent by the mobile control device 10 are not missed even in the case of low power. The conversion efficiency of DC-DC is 90%, and thus, the total power consumption of DC-DC at supplying power to the communication module 231 is 8/0.9=8.89 milliwatts, and assuming that the conversion efficiency of AC-DC of the switching power supply unit 24, i.e., AC 220V, to 3.3V is 80%, the consumption current of the entire series control device 20 in the standby state, i.e., the state in which the lamp is not lit, is 8.89/0.8=11.11 milliwatts. Therefore, when the circuit control system disclosed by the invention is used, the power of the lamps connected in series is as low as 3W during operation, the lamps cannot flash, and the design purpose of the circuit control system disclosed by the invention can be realized. Of course, in other embodiments of the present invention, the load 100, such as a lamp, may be other power, and those skilled in the art will appreciate that the power of the load 100 is not a limitation of the present invention.

In some embodiments of the present invention, the voltage stabilizing module 232 is a BUCK-type DC-DC converter, and the DC-DC conversion efficiency of the voltage stabilizing module 232 is greater than a predetermined value, such as greater than 80%, for low power operation of the non-sleep communication unit 23. In some embodiments of the present invention, the DC-DC conversion efficiency of the voltage stabilizing module 232 is greater than a predetermined value, such as greater than 70%, for low power operation of the non-dormant communication unit 23. In some embodiments of the invention, the voltage stabilizing module 232 is selected from the group consisting of: one of BUCK type DC-DC converter, BOOST BOOST DC-DC converter and LDO voltage stabilizer

Further, in some embodiments of the present invention, the mobile control device 10 transmits the radio frequency signal according to a predetermined procedure. For example, the operation of the mobile control device 10 may be:

when the key 11 of the movement control device 10 is pressed, the generator 12 is caused to generate electricity to generate instant induction pulse energy; after the energy of the electric pulse is stored in a capacitor, an energy oscillator is used for shaping and delaying the energy, for example, the time for the electric pulse to exist is extended to more than 6ms from 1ms, so that the energy for maintaining enough work is supplied to a transmitting circuit to send out a coded signal.

Fig. 4 is a schematic workflow diagram of a mobile control apparatus according to a first embodiment of the present invention. After the mobile control device 10 starts to work after power generation, initializing the mobile control device 10, including initializing a singlechip (work module type setting and peripheral configuration) and a radio frequency chip (radio frequency chip parameter configuration and frequency calibration) of the mobile control device 10; the information of the key 11 is further detected through the input port of the single chip microcomputer of the mobile control device 10 (for example, the seesaw type mobile control device 10 is a high level signal, the rebound type mobile control device 10 is a low level signal), the key 11 signal and the equipment information are formed into an ID to be packaged, and in order to prevent the unstable transmitting signal when the energy is exhausted, a check code is added at the tail part of each package of the signal. Further, the frame format of the radio frequency control signal transmitted by the mobile control apparatus 10 may be: a 4-byte synchronous signal, a 4-byte equipment ID, a 1-byte key signal and 2-byte verification; after the radio frequency control signal is sent, the singlechip and the radio frequency IC enter a dormant state, and after waiting for 3ms, the dormant state is ended, and then the next information sending is started; and judging whether the key information needs to be re-detected before the next transmission. The rebound type self-generating mobile control device 10 needs to re-detect key information every time of transmitting information until the electric energy is exhausted to stop working; every time the seesaw type self-generating mobile control device 10 transmits three packets of data, key information is re-detected, and if no key information exists, information transmission is stopped. It should be noted that the above-mentioned operation of the mobile control device 10 for transmitting radio frequency signals is only used as an example of one of the control signal transmitting processes, and is not a limitation of the present invention, that is, in other embodiments of the present invention, the mobile control device 10 may transmit the control signal through other processes or other encoding manners.

Referring to fig. 14, in some embodiments of the present invention, the mobile control device 10 includes a plurality of keys 11 to control the operation of a plurality of loads 100, in which case, in the radio frequency signal transmitted by the mobile control device 10, the plurality of keys 11 may be distinguished by encoding, for example, the keys 11 may be bit-encoded, to implement a combined key function, or different keys 11 may be implemented to control different loads 100.

Further, in some embodiments of the present invention, the pairing process is required when the mobile control device 10 cooperates with the serial control device 20. That is, the movement control device 10 and the series control device 20 are made to correspond by the pairing process. Preferably, the pairing process is adapted to a situation where a plurality of the mobile devices or a plurality of the keys 11 control a plurality of loads 100, such as for example such that each of the keys 11 controls a different load 100.

Further, the serial control device 20 may include a pairing button communicatively connected to the non-dormant communication unit 23, so as to trigger the non-dormant communication unit 23 to enter a pairing procedure after the pairing button is actuated. That is, the serial control device 20 has a pairing operation mode, and when the pairing button is actuated, the serial control device 20 enters the pairing operation mode to wait for pairing with the mobile control device 10.

For example, the pairing process of the serial control device 20 may be: when the serial control device 20 is in the standby state, pressing the pairing button for a period of several seconds, and flashing an indicator light of the pairing button to enter a waiting pairing mode; the mobile control device 10 sends a pairing control signal to the serial control device 20, the pairing signal is captured by the communication module 231 of the serial control device 20 waiting for pairing, the communication module 231 sends the received pairing signal to the micro-processing control module 233 for storage, after the storage, the indicator light of the serial control device 20 is turned off, and the pairing process is ended. If other mobile control devices 10 or other keys 11 are required to be matched with the serial control device 20, the steps are only needed to be repeated. When the mobile control device 10 includes a plurality of keys 11 to control a plurality of loads 100, the keys 11 may be paired respectively, so as to implement a pairing process of a plurality of keys 11, and after pairing is completed, the serial control device 20 controls the operation of the control switch 22 according to the control information of the keys 11.

For example, the working process of the circuit control system may be: the mobile control device 10 is operated to generate electric power and send a control signal to the serial control device 20, the serial control device 20 receives the control signal and outputs a high level to the switch driving unit 25 from the output port of the micro-processing control module 233 if the control signal is judged to have been paired by the micro-processing control module 233 of the non-sleep communication unit 23 to the key 11; the switch driving unit 25 drives the control switch 22 to be closed, the load 100 is turned on, for example, the lamp emits light, at this time, the potential difference across the control switch 22 is zero, and the switching power supply unit 24 is powered off to stop the operation; the pulse width controller 213 cooperates with the power-taking control unit 21 to obtain electric energy to provide low-power operation for the non-sleep communication unit 23, so as to continuously receive the control signal sent by the mobile control device 10. When the non-sleep communication unit 23 receives the control signal again, the output port of the microprocessor control module 233 outputs a high level to the switch driving unit 25, the switch driving unit 25 drives the control switch 22 to be turned off, and the load 100 does not operate, and at this time, the switch power supply unit 24 operates to provide the non-sleep communication unit 23 with the electric energy of the low power operation.

It should also be noted that the mobile control device 10 of the present invention is directly connected to the serial control device 20 in a communication manner, and no gateway is required as a signal relay. That is, the serial control device 20 is in a non-dormant state to continuously receive the control signal sent by the mobile control device 10, so that a gateway in the prior art is not required to be used as an intermediate medium, and the control signal sent by the mobile control device 10 is transferred and stored, so that a control system is simpler, and the control is more convenient and direct.

Fig. 8 is a block diagram schematically illustrating a serial control device 20 according to a second embodiment of the present invention. Fig. 9 is a circuit schematic of a series control device according to a second embodiment of the present invention.

In this embodiment of the invention, the series control device 20 includes a local switch 26, and the local switch 26 is used for performing control operations locally. That is, in the circuit control system, the operation of the load 100 may be independently controlled by one end of the movement control device 10, or the operation of the load 100 may be independently controlled by one end of the serial control device 20, that is, a combination of wireless and wired dual control may be realized.

Further, the local switch 26 is electrically connected to the micro-process control module 233 so as to send a local control signal to the micro-process control module 233. That is, when the user activates the control switch 22 through one end of the serial control device 20, the control switch 22 transmits a signal to the micro-process control module 233, and the micro-process control module 233 processes the local control signal and transmits a signal to the switch driving unit 25, thereby controlling the on or off of the control switch 22.

The microprocessor control module 233 comprehensively processes the wireless control signal of the mobile control device 10 and the local control signal of the local switch 26, and sends a signal to the switch driving unit 25, so as to independently control the operation of the load 100 by one end of the mobile control device 10 or one end of the serial control device 20.

For example, when the mobile control device 10 sends the wireless control signal to the serial control device 20, the communication module 231 receives the wireless control signal and transmits the signal to the micro-processing control module 233, and the micro-processing control module 233 processes the control signal and, in combination with the current state of the control switch 22, controls the control switch 22 to change from the current state to another state, that is, realizes that the state change of the control switch 22 is independently controlled by one end of the mobile control device 10, that is, the state change of the load 100 is independently controlled by the mobile control device 10. When the user operates the local switch 26 at one end of the serial control device 20, the local switch 26 sends the local control signal to the microprocessor control module 233, and the microprocessor control module 233 processes the local control signal of the local switch 26 and, in combination with the current state of the control switch 22, controls the control switch 22 to change from the current state to another state, that is, realizes that the state change of the control switch 22 is independently controlled by one end of the serial control device 20, that is, the state change of the load 100 is independently controlled by one end of the serial control device 20.

Further, the local switch 26 may be plural, that is, correspond to plural of the mobile control devices 10 or plural of the keys 11 of one of the mobile control devices 10, respectively, that is, an independent double control function is realized by a combination of plural of the local switch 26 and plural of the mobile control devices 10 or plural of the keys 11.

In the manner that the mobile control device 10 and the serial control device 20 of the plurality of keys 11 are matched, the plurality of keys 11 of the mobile control device 10 can be respectively matched with the plurality of local switches 26 at one end of the serial control device 20, namely, each group realizes local and wireless double control.

Fig. 10 is a block diagram schematically illustrating a serial control device 20 according to a third embodiment of the present invention.

In this embodiment of the present invention, the serial control device 20 includes a detection control unit 27, where the detection control unit 27 obtains a zero crossing signal of a circuit from the power taking control unit 21, and controls the control switch 22 to be closed, so as to reduce the impact of the instantaneous heavy current on the control switch 22. For example, the detection control unit 27 may obtain the zero crossing signal of the circuit by the pulse width controller 213, so as to control the closing of the control switch 22 at a predetermined time of the zero crossing signal, that is, to avoid the occurrence of an instantaneous large current caused by the closing of the control switch 22 near the current peak position in the circuit.

Further, in some embodiments of the present invention, the detection control unit 27 is electrically connected to the switch driving unit 25, so as to transmit a signal to the switch driving unit 25, so that the action of the control switch 22 is controlled by the switch driving unit 25 in combination with the information of the detection control unit 27. That is, the switch driving unit 25 controls the operation of the control switch 22 in conjunction with signals of the microprocessor control module 233 and the detection control unit 27. Of course, in other embodiments of the present invention, the detection control unit 27 may be electrically connected in other ways.

The power take-off control unit 21 selectively controls the passage path of the current so as to controllably supply the electric power. More specifically, the power taking control unit 21 is selectively controlled to the control switch 22 and/or the non-sleep communication unit 23. The power taking control unit 21 is electrically connected with the control switch 22 and the non-sleep communication unit 23.

In some embodiments, the non-dormant communication unit 23 and the communication unit 13 of the mobile control device 10 are configured for communication connection.

The control switch 22 is used for controlling the power-taking control unit 21 to be connected with the load 100. That is, when the series control device 20 is connected to the load 100 circuit, the control switch 22 is provided between the power taking control unit 21 and the load 100. When the load 100 needs to operate, the control switch 22 is closed, so that the current passing through the power taking control unit 21 is transmitted to the load 100 through the control switch 22 for the load 100 to operate. When the load 100 does not need to operate, the control switch 22 is turned off, i.e., the current passing through the power take-off control unit 21 cannot reach the load 100 through the control switch 22. In other words, the branch in which the control switch 22 is located provides the load 100 with an operating state of current, such as a current reaching rated power operation, when current reaches the load 100 through the control switch 22, the load 100 can operate normally, when current does not reach the load 100 through the control switch 22, the load 100 does not operate or the load 100 is in a state well below rated power.

The switching power supply unit 24 is electrically connected to the output and output interface 201. In other words, the switching power supply unit and the power take-off control unit and the control switch are provided in parallel with the input and output interfaces.

The switching power supply unit 24 is used for regulating the input electrical energy, such as voltage or current. More specifically, the switching power supply unit 24 regulates the power supplied from the input interface to the load 100 and the non-sleep communication unit 23 so that the current passing through the switching power supply unit 24 to both the load 100 and the non-sleep communication unit 23 is small, thereby making the load 100 not start operation, such as a lamp, not to flicker or emit light, when the current passes only through the switching power supply unit 24 to the load 100, and making the non-sleep communication unit 23 continuously operate at a lower power. The switching power supply unit 24 is disposed on both sides of the power-taking control unit 21 and the control switch 22, and when the control switch 22 is turned on, the switching power supply unit 24 is powered off to stop the operation, and when the control switch 22 is turned off, the switching power supply unit 24 is operated. In other words, when the control switch 22 is closed, the switching power supply unit 24 is short-circuited, and the current does not pass through the switching power supply unit 24, so the switching power supply unit 24 does not operate. The switch power supply unit 24 obtains the electric energy at the closing moment of the control switch 24, so as to enable the non-sleep communication unit 23 to work.

When the series control device 20 is connected to the load 100 circuit, the control switch 22 electrically connects the power taking control unit 21 and the load 100 and the non-sleep communication unit 23. More specifically, the switching power supply unit 24 is provided on both sides of the power take-off control unit 21 and the control switch 22, that is, the input current can be selectively passed through the control switch 22 or the switching power supply unit 24 to the load 100, thereby forming different closed operation loops, such as a load normal operation loop or a series control device low power operation loop.

When the control switch 22 is closed, the switching power supply unit 24 is powered off and stops working, the current passing through the power-taking control unit 21 is transmitted to the load 100 through the control switch 22, so that the load 100 works normally, the non-sleep communication unit 23 and the switch driving unit 25 are directly powered on by the power-taking control unit 21 and keep working, that is, the power-taking control unit 21 provides low-power working current for the non-sleep communication unit 23 and the switch driving unit 25, that is, the non-sleep communication unit 23 works continuously with low power and continuously receives control information sent by the mobile control device 10. When the control switch 22 is turned off, the input current is regulated by the switching power supply unit 24 and then is sent to the non-sleep communication unit 23, and a part of the smaller current is sent to the load 100 to form a closed circuit, such as a low-power closed circuit between the neutral line and the live line, where the current in the circuit is mainly used to maintain the non-sleep communication unit 23, so that the current passing through the load 100 is smaller, and thus the load 100 is not caused to operate, such as when a lamp is blinking or lighting. Thus, the non-sleep communication unit 23 can obtain the operating power regardless of whether the load 100 is in an operating state or the load 100 is in a non-operating state, thereby continuously receiving the signal transmitted from the mobile control device 10, so that the mobile control device 10 is not required to transmit a long signal, and the serial control device 20 can accurately receive the signal transmitted from the mobile control device 10, so that the phenomenon of control confusion does not occur. It should be noted that, when the control switch 22 is turned on or at the moment of being turned on, the switching power supply unit 24 obtains the electric energy at the moment of turning on the control switch 22, so that the non-sleep communication unit 23 and the switch driving unit 25 work, that is, before the power-taking control unit supplies power to the non-sleep communication unit 23 and the switch driving unit 25, the switching power supply unit 24 continues to supply power to the non-sleep communication unit 23 and the switch driving unit 25, so as to ensure that the non-sleep communication unit continuously works without sleep.

Further, when the control switch 22 is turned off, the switch driving unit 25 obtains passing electric power from the switch power supply unit 24, that is, the switch power supply unit 24 supplies operating electric power to the switch driving unit 25 in such a manner that the switch driving unit 25 is electrically connected. When the control switch 22 is closed, the switch driving unit 25 is supplied with power from the switching power supply unit 24 or the power taking control unit 21. In other words, the switch driving unit 25 is electrically connected to the non-sleep communication unit 23, the switching power supply unit 24, and the control switch 22, respectively. The switch drive unit 25 is by way of example but not limitation a relay drive module.

Further, referring to fig. 11 and 12, the power taking control unit 21 includes a first half-cycle control element 211, a second half-cycle control element 212, and a pulse width controller 213, and the first half-cycle control element 211 and the second half-cycle control element 212 selectively control currents of opposite half-cycles, respectively. Preferably, the first half-cycle control element 211 and the second half-cycle control element 212 selectively control currents in opposite directions. For example, in one sinusoidal current cycle, the first half-cycle control element 211 selects to control the current of the positive half-cycle and the second half-cycle control element 212 selects to control the current of the negative half-cycle. That is, the current of the half cycle selectively passes through the first half cycle control element 211, and the current of the other half cycle selectively passes through the second half cycle control element 212. The pulse width controller 213 controls the second half-cycle control element 212 to be turned off at a predetermined interval and to draw power from the circuit to power the non-sleep communication unit 23. In some embodiments, the pulse width controller 213 controls the second half-cycle control element 212 to open a smaller interval at circuit zero crossings.

In some embodiments, the non-sleep communication unit 23 is configured to store electrical energy in an electrical energy storage element, for example, to store electrical energy in an off interval acquired by the pulse width controller 213, for a plurality of cycles of operation of the non-sleep communication unit 23, that is, after one cycle, even if no electrical energy is provided, the electrical energy acquired by the pulse width controller 213 is stored and then continues to power the non-sleep communication unit 24.

The serial control device 20 includes a low voltage switching power supply unit 241, a control switch 22, a switching power supply unit 24, a switch driving unit 25, and a non-sleep communication unit 23.

The low-voltage switching power supply 241 and the switching power supply unit 24 supply power to the non-sleep communication unit 232, in other words, the low-voltage switching power supply 241 and the switching power supply unit 24 are electrically connected to the non-sleep communication unit 23, respectively.

The control switch 22 is used for controlling the power-taking control unit 21 to be connected with the load 100. That is, when the series control device 20 is connected to the load 100 circuit, the control switch 22 is input between the interface 201 and the load 100. When the load 100 needs to operate, the control switch 22 is closed so that the input current is transferred to the load 100 through the control switch 22 for the load 100 to operate. When the load 100 does not need to operate, the control switch 22 is turned off, i.e., the input current cannot reach the load 100 through the control switch 22. In other words, the branch in which the control switch 22 is located provides the load 100 with an operating state of current, such as a current reaching rated power operation, when current reaches the load 100 through the control switch 22, the load 100 can operate normally, when current does not reach the load 100 through the control switch 22, the load 100 does not operate or the load 100 is in a state well below rated power.

In some embodiments of the present invention, the control switch 22 is a semiconductor switching device, such as, but not limited to, a thyristor, MOS transistor, or the like, and it should be understood by those skilled in the art that the particular type of control switch 22 is not a limitation of the present invention. The control switch 22 has an open state and a closed state, and when the control switch 22 is in the closed state, the normal operation circuit of the load 100 is turned on, i.e., the load 100 is normally operated, and when the control switch 22 is in the open state, the normal operation circuit of the load 100 is turned off, i.e., the load 100 is not operated. Preferably, in some embodiments of the present invention, the initial state of the control switch 22 is an off state.

The low voltage switching power supply unit 241 and the switching power supply unit 24 are electrically connected to the input and output interfaces 201, respectively. In other words, the switching power supply unit 24 and the low-voltage switching power supply unit 241 and the control switch 22 are provided in parallel to the input and output interface 201.

The low-voltage switching power supply unit 241 and the switching power supply unit 24 are used for regulating the input electric energy, such as voltage or current. More specifically, the low voltage switching power supply 241 regulates the power from the input interface 201 to the non-dormant communication unit, and the switching power supply unit 24 regulates the power from the input interface 201 to the non-dormant communication unit 23 and the load 100.

More specifically, the switching power supply unit 24 regulates the power supplied from the input interface to the load 100 and the non-sleep communication unit 23 so that the current passing through the switching power supply unit 24 to both the load 100 and the non-sleep communication unit 23 is small, thereby making the load 100 not start operation, such as a lamp, not to flicker or emit light, when the current passes only through the switching power supply unit 24 to the load 100, and making the non-sleep communication unit 23 continuously operate at a lower power. The switching power supply unit 24 is disposed at both sides of the control switch 22, and when the control switch 22 is turned on, the switching power supply unit 24 is powered off to stop the operation, and when the control switch 22 is turned off, the switching power supply unit 24 is operated. In other words, when the control switch 22 is closed, the switching power supply unit 24 is short-circuited, and the current does not pass through the switching power supply unit 24, so the switching power supply unit 24 does not operate. The switch power supply unit 24 obtains the electric energy at the closing moment of the control switch 24, so as to enable the non-sleep communication unit 23 to work.

The non-sleep communication unit 23 includes a communication module 231, a voltage stabilizing module 232, a micro-processing control module 233 and an energy storage module 234, wherein the communication module 231 is used for being in communication connection with the mobile control device 10, the voltage stabilizing module 232 is used for adjusting the electric energy transmitted to the non-sleep communication module 231, and the micro-processing control module 233 is used for processing control signals and sending control information to the switch driving unit 25.

The energy storage module 234 is configured to store electric energy, and more specifically, the energy storage module 234 stores electric energy input by the low-voltage switching power supply unit 241 and/or the switching power supply unit 24.

The energy storage module 234 is electrically connected to the voltage stabilizing module 232, and supplies power to the voltage stabilizing module 232, that is, the electric energy stored by the energy storage module 234 is regulated by the voltage stabilizing module 232 and then supplied to the non-sleep communication unit 23 to work.

In some embodiments of the present invention, the low voltage switching power supply unit 241 and the switching power supply unit 24 are electrically connected to the voltage stabilizing module 232 so as to regulate the power delivered by the switching power supply unit 24 through the voltage stabilizing module 232. That is, the power supplied from the low voltage switching power supply unit 241 and the switching power supply unit 24 to the non-sleep communication unit 23 can be regulated by the voltage stabilizing module 232 to ensure the low power stable operation of the non-sleep communication unit 23.

In some embodiments of the present invention, when the control switch 22 is turned off, the switching power supply unit 24 operates, power is obtained from both sides of the control switch 22, and a closed loop is formed with the load 100 to supply power to the non-sleep communication unit 23. The switching power supply unit 24 is a BUCK regulator circuit, such as a BUCK step-down circuit, so that the current flowing through the switching power supply unit 24 to the load 100 is relatively small, and the load 100 does not operate, such as causing flickering of a lamp. In other words, when the control switch 22 is turned off, the circuit current constituted by the switching power supply unit 24, the non-sleep communication unit, and the load is small by the action of the switching power supply unit 24, so that the load 100 is not operated and the non-sleep communication unit 23 is operated with low power consumption.

In some embodiments of the present invention, when the control switch 22 is closed or at the moment of closing, the switching power supply unit 24 obtains the closed electric energy and stores it in the energy storage module 234, so as to continue to operate the non-sleep communication unit 23.

When the control switch 22 is turned on or after a predetermined time, the switching power supply unit 24 is powered off to stop the operation, the input current is transmitted to the load 100 through the control switch 22, so that the load 100 operates normally, and the non-sleep communication unit 23 and the switch driving unit 25 are powered by the low-voltage switch power taking unit 241 to maintain the operation. The low-voltage switch power-taking unit 241 supplies the non-sleep communication unit 23 and the switch driving unit 25 with a low-power operating current, i.e., the non-sleep communication unit 23 is continuously operated with low power and continuously receives the control information transmitted from the mobile control device 10. For example, after the control switch is turned on, the storage module 234 provides electric energy for the non-sleep communication unit to operate, when the current in the circuit passes through zero, the control switch 22 is controlled to be turned off for a predetermined interval, the low-voltage switch power supply unit 241 obtains electric energy for the predetermined interval and regulates and transmits the electric energy to the non-sleep communication unit 23, that is, the low-voltage switch power supply unit 421 obtains electric energy for the non-sleep communication unit 23 to be turned off for a short time when the load 100 is in an operating state, and the non-sleep communication unit 23 is operated, and is selectively turned off in a zero crossing point position, in a smaller voltage range, and the turning-off moment is short, so that the normal operation of the load is not affected, for example, the flickering phenomenon of the lamp is not caused. For example, the low-voltage switching power supply unit 241 can be a BOOST-type converter, such as a BOOST-type converter, so that the obtained voltage is small, but the voltage provided to the non-sleep communication unit 23 is high, or the non-sleep communication unit can be made to continue to operate normally in a state where an extremely low voltage is obtained. For example, the electric energy obtained by the low-voltage switching power supply unit 241 is stored in the energy storage module 234, so that the non-sleep communication unit 23 can operate, for example, at least the sleep communication module 23 can operate until the next period, the control switch 22 is opened again for a predetermined interval, and after the low-voltage switching power supply unit 241 obtains the electric energy again, the low-voltage switching power supply unit 241 and the energy storage module 234 repeat this operation, and when the control switch 22 is closed and the load 100 operates, the non-sleep communication unit 23 is continuously powered.

In other words, when the control switch 22 is turned off, the current input through the switching power supply unit 24 is regulated and then sent to the non-sleep communication unit 23, and a part of the smaller current is sent to the load 100 to form a closed circuit, such as a low-power closed circuit between the neutral line and the live line, where the current in the circuit is mainly used to maintain the non-sleep communication unit 23, so that the current through the load 100 is smaller, and thus the load 100 is not caused to operate, such as when a lamp is blinking or lighting. Thus, the non-sleep communication unit 23 can obtain the operating power regardless of whether the load 100 is in an operating state or the load 100 is in a non-operating state, thereby continuously receiving the signal transmitted from the mobile control device 10, so that the mobile control device 10 is not required to transmit a long signal, and the serial control device 20 can accurately receive the signal transmitted from the mobile control device 10, so that the phenomenon of control confusion does not occur. It should be noted that, when the control switch 22 is turned on or at the moment of being turned on, the switching power supply unit 24 obtains the electric energy at the moment of turning on the control switch 22, so that the non-sleep communication unit 23 and the switch driving unit 25 work, that is, before the power-taking control unit supplies power to the non-sleep communication unit 23 and the switch driving unit 25, the switching power supply unit 24 continues to supply power to the non-sleep communication unit 23 and the switch driving unit 25, so as to ensure that the non-sleep communication unit continuously works without sleep.

The switching power supply unit 24 is exemplified by, but not limited to, a switching power supply module, and of course, the switching power supply unit 24 can also enable other power supply regulating devices, for example, the switching power supply unit 24 is a BUCK AC-DC converter, such as a BUCK converter, and the voltage output by the switching power supply unit 24 ranges from 1.5V to 24V, for example and not limited thereto. The low-voltage switching power supply unit 241 is a BOOST AC-DC converter, such as a BOOST type converter, and the voltage range output by the low-voltage switching power supply unit 241 is 1.5-24V.

In some embodiments of the present invention, the low voltage switching power supply unit 241 is a pulse taking buck converter and the switching power supply unit 24 is a buck converter.

In some embodiments of the invention, the voltage stabilizing module is selected from the group consisting of: the switching device comprises one of a BUCK type DC-DC converter, a BOOST BOOST DC-DC converter and an LDO voltage stabilizer.

In some embodiments of the invention, the communication module is an integrated circuit having high frequency receiving and/or transmitting functions.

In some embodiments of the present invention, when the time of the control signal sent by the mobile control device 10 does not exceed 50ms, the serial control device 20 makes an immediate response to control the operation of the load 100 without affecting the operation state of the load 100

In some embodiments of the invention, the control switch 22 is a semiconductor switching device.

Fig. 14 is a schematic perspective view of a tandem control apparatus 20 according to a sixth embodiment of the present invention.

In this embodiment of the present invention, the movement control device 10 includes a plurality of the keys 11, and the series control device 20 controls the operations of a plurality of the loads 100, respectively, that is, the circuit control system is applied to a control loop for the operations of a plurality of the loads 100.

Further, the series control device 20 includes a plurality of control switches 22, and each control switch 22 is configured to control the power taking control unit 21 to be connected to and disconnected from a circuit of the corresponding load 100. That is, when the series control device 20 is connected to the load 100 circuit, each of the control switches 22 is provided between the power taking control unit 21 and the load 100. When the corresponding load 100 needs to operate, the control switch 22 is closed, so that the current passing through the power taking control unit 21 is transmitted to the load 100 through the control switch 22 for the corresponding load 100 to operate. When the load 100 does not need to operate, the corresponding control switch 22 is turned off, i.e., the current passing through the power taking control unit 21 cannot reach the load 100 through the control switch 22. In other words, the branch in which the control switch 22 is located provides the load 100 with a current in an operating state, such as a current reaching a rated power operation, when the current reaches the load 100 through the control switch 22, the load 100 can operate normally, and when the current does not reach the corresponding load 100 through the control switch 22, the load 100 does not operate or the load 100 is in a state far below the rated power.

In some embodiments of the present invention, the plurality of control switches 22 are driven to operate by one switch driving unit 25, and one switch driving unit 25 controls the operation of the plurality of control switches 22, and thus controls the operation of the plurality of loads 100. While in other embodiments of the present invention, the series control device 20 may include a plurality of switch driving units 25, each of the switch driving units 25 driving a corresponding one of the control switches 22, respectively, it should be understood by those skilled in the art that the corresponding control manners of the driving units and the control switches 22 are not limitations of the present invention.

Referring to fig. 15, a schematic diagram of a circuit control system according to a seventh embodiment of the present invention is shown. In this embodiment of the present invention, the circuit control system includes a plurality of the mobile control devices 10, a plurality of the series control devices 20, and a back gateway 30, the back gateway 30 comprehensively managing the operations of the plurality of loads 100 controlled by the plurality of the mobile control devices 10 and the plurality of the series control devices 20.

Further, each of the mobile control devices 10 and each of the tandem control devices 20 are directly connected in communication, and the rear gateway 30 is connected in communication with the tandem control devices 20 and feeds back control information to each of the tandem control devices 20, thereby coordinating the operations of the plurality of tandem control devices 20, that is, coordinating the operations of the plurality of loads 100. For example, during the operation, each of the mobile control devices 10 sends a signal to each of the serial control devices 20, the serial control devices 20 further transmit information to the back gateway 30, and the back gateway 30 feeds back information to each of the serial control devices 20 according to a pre-fabricated control mode, so as to control the cooperation of each of the loads 100 according to a predetermined requirement.

Further, the gateway 30 may form a load control system, for example, a load control system that may be mounted on a mobile device, and further may control the operation of a plurality of loads through the mobile device by setting an application APP on the mobile device side, or preset the operation mode of a plurality of loads. For example, the back gateway 30 may manage any of a plurality of serial control devices 20 connected in series with the lamps, so as to form a scene control, that is, a cloud or app may implement a combined switch control on a plurality of lamps, for example, there are 10 lamps, in some scenes, the lamps 1, 3, 5, 7, 9 need to be turned on, and the lamps other are turned off, and in some time periods, the lamps 2, 4, 6, 8, 10 need to be turned on, so as to implement a preset grouping scene control function.

Referring to fig. 16, according to the above embodiment of the present invention, the present invention provides a circuit control method, which is characterized by comprising the steps of:

transmitting the control signal by a mobile control device 10 in a self-generating manner;

receiving the control signal through a serial control device 20 without dormancy; and

the operation of a load 100 is controlled in series by the series control device 20 according to the control signal.

In the circuit control method of the present invention, the mode of transmitting the control signal from the power generation site and the mode of controlling the operation of the load 100 in series are combined, so that the advantages of the power generation site and the control in series can be combined with each other, and the control signal can be completely received, thereby realizing sensitive control.

Further, in the step of transmitting the control signal from the power generator, the pairing code may be transmitted so that both ends of the control can be accurately paired to control, that is, the control end and the controlled end correspond.

The control signal is received without dormancy, so that the transmitted control signal can be completely received, and the control signal can be received at a long or terminal.

Further, in the step of controlling the operation of the load 100 in series, when the load 100 is in a non-operating state, the series control device 20 is in a low-power operating state.

In the step of receiving the control signal through the serial control device 20 without dormancy, the current or voltage parameter in the circuit is monitored, a second half-cycle control element 212 is controlled to be disconnected in a predetermined interval, and electric energy at two sides of the second half-cycle control element 212 is obtained for the non-dormancy communication unit 23 to work.

In the step of receiving the control signal through the serial control device 20 without sleep, the power supplied to the non-sleep communication unit 23 is regulated to operate at low power.

In the step of controlling the operation of the load 100 in series by the series control device 20, the operation of the load 100 is controlled by the local switch 26 at one end of the series control device 20.

It will be appreciated by persons skilled in the art that the embodiments of the invention described above and shown in the drawings are by way of example only and are not limiting. The objects of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been shown and described in the examples and embodiments of the invention may be modified or practiced without departing from the principles described.
