Decree. Reference numeral 101 denotes a relay station that is installed in a substation or the like and relays the load control command, and 102 denotes a transmitting device (transmitting unit) that wirelessly transmits the load control command via a transmission antenna 103. On the other hand, 1 is an antenna,
Reference numeral 2 denotes a receiving unit, 3 denotes a decoder unit for decoding and comparing the ID code of the load control command received via the antenna 1 and the receiving unit 2, and 4 denotes a non-volatile memory which stores a pre-assigned common ID code. A read-only ROM unit, 5 is a CPU that controls the entire load control terminal device, 6 is a memory unit that stores programs executed by the CPU 5 and message commands, and 7 is a digital output interface. Of the load control terminal device 8 is configured. 9 is a load to be controlled. The terminal device 8 is provided in the vicinity of the load 9 to be controlled. However, it is preferable that the terminal device 8 be housed in a small box or the like and attached to the load 9 to be controlled. Also, the ID code is stored in
Instead of the ROM unit, a memory unit with a power failure countermeasure may be used.

Next, the operation will be described. When the power demand increases and the master station device 100 determines that it is necessary to cut off some of the plurality of loads scattered in various places, the master station device 100 provided in the power company is provided exclusively for the power company. A load control command including an ID code indicating load control, a control target, and a message command indicating control content is transmitted to the relay station 101, and a radio wave is transmitted through the transmission device 102 and the transmission antenna 103 to the area in charge. As shown in the flowchart of FIG. 3, the load control terminal device 8 captures the radio signal transmitted from the master station by the antenna 1, demodulates the signal received by the receiving unit 2, and sends the demodulated signal to the decoder unit 3 (S3).
1). The decoder unit 3 checks whether the transmitted digital data does not include an ID code previously written in the ROM unit 4 (S32), and if it does, determines that it is a load control signal. Then, the subsequent message command is stored in the memory unit 6 via the CPU 5 (S33).
The ID code indicates whether or not the load control is performed. Even if the ID code is composed of only numbers as shown in FIG.
Both alphanumeric and mixed. An example of the message command is also shown in FIG. 2, but as in this example, a code such as "stop area 123 group 45 for 5 minutes" or a code that can be determined only by a machine may be used. Determine message command at CPU5 in the terminal device 8 (S34), the

When it is determined that the device is to be controlled, the control output is sent to the load 9 via the digital output interface 7 (S35), and control such as shutting off the switch is performed. Is carried out. This operation is performed almost simultaneously independently for each terminal device, so that a plurality of loads can be controlled simultaneously. According to the present embodiment, since only one ID code is used for load control from one master station device, the setting of the ROM section of each terminal device may be the same,
Terminal equipment can be mass-produced and one message
A large number of terminal devices 8 that have received the
Control, so that the communication line is not occupied for a long time ,
Because it is not necessary to call one by one at the time of control,
The time is greatly reduced, the communication fee is significantly reduced, and the effect of load control becomes easy. In addition, load is classified by area, group, etc.
It can be controlled by one load control command if necessary.
For example, stop the load for a certain amount of time

Control such as stopping for a certain time by shifting the time is possible
Becomes In addition, the terminal device is installed in close contact with the load and wireless is used as the transmission medium, so even if the load target is changed or added, it can be carried out without performing large-scale construction such as wiring work. There is also.

Embodiment 2 FIG. Next, an embodiment in which control is performed by comparing with a set value set for each target load will be described with reference to FIGS.
It will be described based on. In FIG. 4, 10 is a switch, 1
1 is a power line such as a distribution line, 12 is a wiring in the premises, and 13 is a CT.
(Instrument current transformer), 14 is PT (instrument transformer), 15
Measures the current or power by the CT13 and PT14, and when the measured value exceeds the set value, the switch 10
Control device (control means), which has an antenna 1, and sets and changes set values of current and power based on a load control command from a master station device, and a load control terminal device of this embodiment, Is a switch (SW) provided for each load, 18
Is the load. Note that the internal configuration of the load control terminal device 16 is substantially the same as that shown in the first embodiment of FIG.
Control device 1 via digital output interface 7
5 is connected, and set values such as current and power are set and changed. Further, since the master station apparatus side is the same as that of FIG. 1, it is omitted (the same applies to the following embodiments).

Next, the operation will be described with reference to the flowchart of FIG. First, the terminal device 16 receives a set value indicating a limit of current or power as a load control command from the master station device, and stores it in the memory (S51). on the other hand,
The current or power passing through the control device 15 via the CT 13 and the PT 14 installed on the power supply line 11 is measured (S52), and when the current or the power exceeds the set value, a switching control command is sent to the switch 10. The supply to the load 18 is restricted (S53, S54). By adopting such a configuration, it is not necessary to determine the situation of each customer on the master station side and issue individual control commands, and load control can be realized by sending the same commands all at once. Furthermore, if the consumer performs an operation of disconnecting the non-critical load in advance by using the switch 17 provided for each load 18, there is an effect that the important load can be maintained even when the load control command is received. In addition, there is an effect that even if there is a sudden contract change request by a telephone or the like from the consumer regarding the current set value, it is possible to immediately respond by changing the set value signal to the terminal device 16.

Embodiment 3 FIG. An embodiment in which the degree of cooperation of the consumer with the load control can be determined will be described with reference to FIGS. In FIG. 6, 1 is an antenna, 2 is a receiving unit, 3
Is a decoder unit, and 4 is a ROM storing an ID code.
5, a CPU 6, a memory 6, a cooperation counter 6a and a cooperation time counter 6a, 6b provided in the memory 6, a digital output interface 7, a switch 10, a CT 13, a CT 13 and a CT 20 An analog input interface 21 for inputting a detection value is a load control terminal device according to the present embodiment.

Next, the operation will be described with reference to the flowchart of FIG. Switch 10 based on a command from the master station
When the control is performed, the current value before control is read through the CT 13 and the analog input interface 20 and stored in the memory unit 6 (S71). Switch 10
Similarly, the current value after the control is executed is stored in another location of the read memory unit 6 (S72). next,
The difference between the two current values is determined (S73), and if the rate of decrease is greater than a predetermined value, the customer stops power supply in cooperation with load control while using the power. It is determined that it is lost (S74), and the cooperation number counter 6a provided in the memory unit 6 is incremented and the accumulation of the cooperation time counter 6b is started (S75, S76). When the current value returns after receiving the input control from the master station device, the integration of the cooperation time is ended (S77). If a load control command is received for a load that is not used from the beginning, the current value does not change before and after the control and it is not determined that they cooperated.
Neither the cooperation counter 6a nor the cooperation time counter 6b is updated. By adopting such a configuration, it is possible to determine how much the customer cooperated with a one-way control system such as a wireless system, and it is possible to reflect this in a reward system for cooperation such as a fee discount. This has the effect of preventing a fraudulent act of applying for registration as a controlled object load to an electric device that has not been attempted to obtain a discount. In the above embodiment, the current is used as the measured amount. However, the same effect can be obtained as long as it is possible to determine whether or not the customer is using the power or the water amount.

Embodiment 4 FIG. Next, FIG. 8 shows an embodiment in which the degree of cooperation of the customer with respect to the load control is collectively transmitted to a power company or the like.
This will be described with reference to FIG. 8, reference numeral 10 denotes a switch, 13 denotes a CT, 14 denotes a PT, and 21 denotes an antenna 1, a load control terminal device having a transmission function added to that of the third embodiment (FIG. 6), and 30 denotes an antenna 1 A transmission / reception device (aggregation means) for transmitting / receiving data to / from each terminal device 21 in the same premises in order to aggregate the degree of cooperation of the customer, 31 is a power amount measurement device, 32 is communication between the power company Device (transmitting means).

Next, the operation will be described with reference to the flowchart of FIG. In order to combine the values of the number of cooperation times and the integrated time of cooperation measured by each load control terminal device 21 into the same premises, the load control terminal device 21 is sequentially called from the transmission / reception device 30 to transmit and collect data (S91, S9).
2, S93). On the other hand, an electric energy measuring device 31 for measuring electric energy is installed at a power receiving point contracted by a consumer and an electric power company, and this data is read by a patrol person or transmitted via a telephone line or a dedicated line. It may have been sent to the power company. In order to calculate the electricity rate, both the amount of power at the receiving point and the degree of cooperation with the load control to be discounted are necessary, and by transmitting these together to the power company through the communication device 32, It takes time to collect data by going around the premises sequentially (S94, S9)
5). Applying a device that collectively transmits data in the same premises to a power company for a large customer who installs a plurality of load control terminal devices in this way can significantly reduce the power company's patrol personnel. This is effective for speeding up fee calculation.

Embodiment 5 FIG. Next, a fifth embodiment will be described with reference to FIGS.
It will be described based on. In FIG. 10, 10 is a switch,
Reference numeral 33 denotes a load control terminal device having the antenna 1 and having a function of controlling sound output and display output; 34, a sound generator for performing load control notification by sound; and 35, a display for performing load control notification by display. Device.

Next, the operation will be described with reference to the flowchart of FIG. If the load is suddenly cut off due to the convenience of the electric power company, there may be a case where the work of the customer is greatly hindered. In order to eliminate such inconvenience, after receiving the load control command and before actually shutting off the load, the user is notified by voice or text about how many minutes later the load limit is to be performed (S111, S112, S113). ), And then perform control output (S114), so that the customer can switch the power supply in advance or stop unnecessary load in the case of load control based on the set value, thereby reducing the load. Guidance becomes possible. The sound generation device 34 may be installed near the load to be controlled or near the place where the operator is located. The display device 35 may also give an image warning in addition to the load control notice using characters.

Embodiment 6 FIG. A sixth embodiment will be described with reference to FIGS. Note that the same or corresponding parts as those of the first embodiment (FIG. 1) are denoted by the same reference numerals, and description thereof will be omitted. FIG.
In 2, the reference numeral 36 denotes a time delay setting device for individually setting the time delay of the control output of the input control, and 37 denotes a load control terminal device according to the present embodiment.

Next, the operation will be described with reference to the flowchart shown in FIG. When large-scale load control is performed at the same time, turn-off control is executed almost at the same time and turn-on control after a certain period of time is also executed almost at the same time, which may cause problems such as power system fluctuation due to inrush current at turn-on. There is. If it is attempted to individually send out control commands to prevent this, it takes too much time and effective load control cannot be performed. Therefore, a time delay setting device 36 is provided for each terminal device, and 2 seconds, 4 seconds, 6
Preset to seconds ... Upon receiving the load control command (S131), it is determined whether or not the input control is performed (S132).
At the time of the cutoff control, the cutoff control is performed simultaneously (S13
6) The load reduction effect increases quickly, and the input control is performed after a preset time delay without individually controlling from the master station during the input control (S133, S134, S13).
5) There is an effect of reducing the influence of the inrush current. It is preferable that the preset time delay data be changed periodically by a communication signal from the master station periodically to further reduce unfairness.

Embodiment 7 FIG. Embodiment 7 will be described with reference to FIGS. 14, 15 and 16. FIG. Note that the same or corresponding parts as those of the first embodiment (FIG. 1) are denoted by the same reference numerals, and description thereof will be omitted. In FIG. 14, reference numeral 40 denotes a temperature sensor (measuring means) for measuring the outside air temperature, 41 denotes an analog input interface for inputting the output of the temperature sensor 40, and 42 denotes settings for setting weekdays, holidays, special days, and the like. The circuit 43 is a load control terminal device according to the present embodiment.

In the conventional apparatus, even when load control is performed almost at the same time every day, it is necessary to send a control command each time to control the load. Control commands are sent at different timings, which takes time. In most cases, the load to be controlled is determined by the distinction between weekdays, holidays, special days, and the like and the outside air temperature. Therefore, a setting circuit 42 for setting weekdays, holidays, special days, and the like is provided, and the outside air temperature is measured. By providing the temperature sensor 40 outside the terminal device 43 and performing repetitive control based on these data based on a load control pattern as shown in an example in FIG. 15, the burden on the master station device is greatly reduced. You can do it. That is, the process shown in the flowchart of FIG. 16A is started, for example, every hour, and the setting circuit 42 is read (S161), the outside air temperature is read from the temperature sensor 40 (S162), and the optimal control is performed. The pattern is registered (S163). On the other hand, the process shown in the flowchart of FIG. 16B is started, for example, every minute, and is checked against the control pattern registered as described above (S164), and it is determined whether or not it is the control timing (S16).
5) If it is a control timing, a control output is performed (S1).
66). The load control pattern shown in FIG.
If it can be changed for each load type to be used, further effects can be expected. The load control pattern is stored in the memory unit 6 by a load control command from the master station device, for example.
And so on.

Embodiment 8 FIG. An eighth embodiment will be described with reference to FIGS. The same or corresponding parts as in the first embodiment (FIG. 1) are denoted by the same reference numerals, and the description thereof will be omitted. FIG.
7, a selection switch (selection means) 44 selects a control mode of continuous cutoff control-intermittent control possible-control rejection;
Reference numeral 45 denotes a load control terminal device according to the present embodiment.

Next, the operation will be described with reference to the flowchart of FIG. The customer uses the selection switch 44 in advance to enable continuous disconnection control for non-critical loads that can be stopped for a while, and for intermittent control for critical loads that can cooperate with load control. Among those that are unlikely to cooperate with load control, the position of control refusal is selected. After receiving a command from the master station (S181), the state of the selection switch 44 is read and the control mode is determined (S182, S183). (S
184). When the intermittent control is possible, the on-off control is performed once after the off-time control is performed (S18).
5, S186, S187). In the case of control refusal, no control is performed even if a command is received. As described above, if the control level of the load to be controlled can be selected at the convenience of the consumer, it becomes possible to easily participate in the load control,
This has the effect of spreading load control.

Embodiment 9 FIG. The ninth embodiment will be described with reference to FIGS. Note that the same or corresponding parts as those of the first embodiment (FIG. 1) are denoted by the same reference numerals, and description thereof will be omitted. FIG.
In 9, reference numeral 46 denotes a clock circuit (first clock means), 47 denotes a clock circuit 46 and a post-rewrite timer (second clock means) for counting the elapsed time after rewriting of setting data, and 48 denotes temporary storage of rewriting setting data. Reference numeral 49 denotes a load control terminal device according to the present embodiment.

Next, the operation will be described with reference to the flowchart of FIG. At the time of simultaneous change of setting data due to simultaneous change of time or change of fee system due to introduction of the summer time system, data to be changed is transmitted in advance from the master station to each terminal device 49 and accumulated in the temporary storage unit 48. . When the value of the timer 47 after the rewriting is equal to or more than a predetermined value and the time designated to change is reached (S201, S202), the clock circuit 46
At the same time and the setting data in the memory unit 6 are changed simultaneously (S203, S204), and the timer 47 after rewriting is changed.
Is reset to zero, and re-counting is started (S20).
5). This is to prevent the occurrence of hunting due to the time to be changed many times when a change is made to delay the time, as shown in FIG. Is not processed (S201). By adopting such a configuration, even if a change in the social system occurs, there is an effect that the setting data and the clock of each terminal device can be changed at the same time and can be dealt with immediately.

Embodiment 10 FIG. FIG. 21 and FIG.
It will be described based on. The same or corresponding parts as in the first embodiment (FIG. 1) are denoted by the same reference numerals, and description thereof will be omitted. In FIG. 21, reference numeral 50 denotes a digital output interface, reference numeral 51 denotes an activation detection circuit for detecting activation of the load 9,
52 is a stop detection circuit for detecting the stop of the load 9, 53 is a digital input interface, and 54 is a load control terminal device according to the present embodiment. Note that the start detection circuit 51
The stop detection circuit 52 detects the start / stop by monitoring the current of the power supply line connected to the compressor that consumes the largest power in the cooler, or extracts the start / stop signal from the control circuit of the cooler. , Can be realized.

Next, the operation will be described. When running / stopping repeatedly with a cooler or large electric equipment, if the control is attempted immediately after receiving the command from the master station, the control is well engaged because it is just before starting, or it is just after starting and it is not possible to stop immediately. There are no cases. A start detection circuit 51 for detecting the start of the load 9 and a stop detection circuit 52 for detecting the stop are provided. As shown in the timing chart of FIG. 22, control is immediately performed even when the terminal device 54 receives a control command from the master station. Instead, the control content is stored in the memory unit 6, and the control is executed after a predetermined time has elapsed since the load was started.
By performing measures such as not performing the on-state control until a certain time has elapsed after detecting the stop, there is an effect that cooperative load control can be realized. The elapsed time from the start or stop detection to execution of the control may be set in advance, or may be set by a load control command from the master station device.
