Under the system of the master-slave architecture of the present invention, the main power unit 50 can obtain power usage information and statistical data of each slave power unit 55, and these records can be stored in the main memory unit 503. In one of the implementations, these electricity records can be used as a reference for future electricity use.

Furthermore, based on the past use inertia, the system will be able to detect the time, area, type and other information of the abnormal power generation and issue a warning, or provide further information for other back-ends to obtain information and then respond appropriately.

The main power unit 50 has a main instructing unit 506, and the main instructing unit 506 can convert the message indicated by the main micro processing unit 501, especially according to the operation schedule in the power unit, such as on the main power interface 509 panel. The main light-emitting element 510 is provided, and can be various forms of indications such as a light-emitting diode, a display panel, and a light-emitting device. The light-emitting element or the related light-emitting device can be illuminated according to a control signal generated by a control program in the mobile device; or When the plurality of sensors are triggered, the signal is generated by the signal braking generated by the main sensing signal processing unit 502, such as an indication signal for generating a warning, or various signals for displaying an internal operating state of the unit.

The main power unit 50 is provided with a switch, preferably implemented as a main relay 507 as shown, and can be used as an operation mode switching circuit of the main power unit 50. The main relay 507 can be a preset controlled mode of electric power. Each power unit can be controlled by an external device or system. As shown in FIG. 4, one of the embodiments can switch the mode in which the main power unit 50 operates through a physical switch on the panel, including at least a manual and a controlled mode. The main power unit 50 is connected to the external uninterruptible power system 52 through the main relay 507, and is connected Go to power supply 54. In the power management system, the main power unit 50 is more electrically connected to one or more slave power units 55, and the connection relationship of the power lines is connected to the slave power unit 55, for example, through the contacts of the uninterruptible power system 52. .

The circuit design from the power unit 55 can be similar to the main power unit 50, but the range of signal processing from the microprocessor unit 551 of the power unit 55 is only limited to operation from the power unit 55, including processing from The control signal of the main power unit 50 and various data transmitted to the main power unit 50.

The slave power unit 55 is provided with a slave processing unit 551 that can process the signal from the power unit 55 and externally transmitted signals, and also electrically connects the circuit units of the slave microprocessor unit 551, and operates as the main power. Each internal circuit of the unit 50.

This example shows that the slave sensing signal processing unit 552 is provided from the power unit 55, thereby being connectable to the externally located sensor 525 for processing the sensing signals generated by the sensors 525. A slave communication unit 554 is provided from the power unit 55 to establish a connection with the main power unit 50. The power unit 55 is provided with an indicating unit 556 that can execute an indication signal, and the indicating unit 556 further controls the light-emitting element 560 provided on the slave power interface 559. The slave memory unit 553 from the power unit 55 can be any form of memory medium, including non-volatile memory or volatile memory, primarily storing programmable programming schedules from the power unit 55. The schedule is taken (programmed) by the main power unit 50, so the slave power unit 55 can perform specific functions in various situations according to this schedule.

The slave relay 557 from the power unit 55 can be a predetermined controlled mode of power, and thus each slave power unit 55 can be controlled by the in-system main power unit 50. However, it can also be operated as a manual mode or a controlled mode. When set to the manual mode, the slave power unit 55 may only be as a general power outlet; when set to the controlled mode, it is controlled by the power management system. Various operational needs are required. From the power management unit 558 of the power unit 55, the power consumption information transmitted from the power interface 559 can also be obtained and counted. Relay 557 can also be designed for anti-surge circuits.

List a scenario example where multiple power cells (50, 55) in a system are Light-emitting elements (510, 560) are provided so that actions that match each other can be made for the same event. Because of an event, the power cells (50, 55) in different locations can individually respond to the same event in different lighting modes, so that multiple power cells (50, 55) of the overall system present a complete event in a situation. For example, in the embodiment shown in Figure 2, multiple power cells show an escape route.

Each of the light-emitting elements (510, 560) can be used as an auxiliary illumination, a message indication, a color change, a flicker, a pattern change, or the like, which can be used to reflect a power abnormality sensed by the power unit, or an environmental change sensed by the sensor, or Specific messages, such as instructions for escape routes, warning messages, etc.

In another case scenario, since the main power unit 50 and the slave power unit 55 can pass through the respective relays (507, 557) as a circuit that interfaces the uninterruptible power system 52 with the power source 54, it can be turned off, turned on, and controlled. The switching element can be operated as a surge-proof circuit to protect internal components and external electrical appliances. When the main power unit 50 learns that there is a problem of power abnormality from obtaining various messages (for example, from the power unit 55), the signal can be transmitted via the master-slave communication unit (504, 554), by the main relay 507 or the slave relay 557. The power supply capability of each unit is turned off, but the minimum power to maintain operation can still be obtained from the uninterruptible power system 52, for example, the light-emitting elements (510, 560) can still be activated in an emergency state, or the signals of the sensors can still be obtained continuously. It also needs the ability to get a message to restart the power supply capability at any time. For another example, when a certain one senses the danger of overcurrent generated from the single sensor, the power supply function of the slave unit can be separately turned off to ensure that other monomers on the same circuit can be powered normally, without causing The dangerous situation of individual cells affects the power supply function of the whole circuit, which is enough to improve the shortcomings of the current power supply system.

Several embodiments of the control program executed in the above power management system can be referred to the flow of the embodiment shown in FIGS. 6-8.

According to the flow shown in FIG. 6, in step S601, when each power unit senses an abnormal event through the set sensor, such as excessive temperature, abnormal power consumption, smoke, etc., the related information is as shown in step S603. Transfer to the main power unit, does not exclude the main The power unit itself is also connected to a sensor.

In step S605, the main power unit performs subsequent measures according to the type of the sensing message, and generates and transmits a control signal to each power unit. At this time, in step S607, each power unit generates an indication according to the operation schedule. message. It is worth mentioning that the operation schedule of each power unit, such as a command and operation checklist, allows each power unit to compare the control signal transmitted by the main power unit to a specific operational procedure, as shown in Figure 2. Implementation situation.

Figure 7 then describes an embodiment of the measures taken in accordance with the power usage information. Beginning in step S701, the main power unit can periodically obtain power usage information of each power unit, including actively accessing data in each power unit memory unit, and also including each power unit being periodically or irregularly transmitted to the main power sheet. Body data. Then, in step S703, the main power unit accumulates the power consumption information of each power unit. After a period of time statistics and analysis, in step S705, a schedule corresponding to each power unit can be generated. In step S707, according to step S707, The power consumption information of the power unit sets the operation of the power unit, such as setting the peak and peak power consumption, and can actively turn off the power when the power is not needed, thereby achieving the purpose of power saving.

For example, when the power consumption information is collected for a period of time, the power supply mode of a specific power interface (specific power unit) can be analyzed, so when there is a special power generation, unlike the usual power consumption, the system can be pre- It is judged that this is an abnormal power supply, so a reminder is issued, or a power-off signal is issued. The power usage information will be transmitted to the external device for monitoring and storage for future reference, as in step S709.

The flow shown in FIG. 8 is a follow-up measure implementation when an abnormality occurs in the specific power unit power consumption information.

Beginning in step S801, the main power unit obtains power consumption information from the power unit for storage and statistics. When it is determined that the power consumption is abnormal, in step S803, the main power unit can generate and transmit a control signal, for example, through the foregoing The wired or wireless channel between the power cells transmits a signal, as in step S805. In the slave relay controlled mode, the slave power unit can be controlled to turn off the power supply function of the power unit, as in step S807. If From a system perspective, it is possible to use a local loop with power, and the associated signal can also directly close a local loop.

The power management system is composed by combining a plurality of power supply devices proposed by the present invention, wherein a main power unit and one or more slave power units are provided, and the main power unit and one or more slave power units can be wired or wireless. The communication channel is connected. The connection between the mobile device and the mobile device is established through a wired or wireless communication channel, through which the mobile device can access the system and further perform control, scheduling and monitoring functions through the installed remote control program.

However, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Therefore, equivalent structural changes that are made by using the specification and the contents of the present invention are equally included in the present invention. Within the scope, it is combined with Chen Ming.
