The load control data can be established in the database 10 by planning and classifying the load 22 in advance by the management personnel and connecting the electronic device with the power control system 1 .

For example, referring to FIG. 3 , the types of predetermined environmental events include, for example, water cutoff, power cutoff, low temperature, etc., but not limited thereto. The load 22 is exemplified by water tower pumping motors, backup charging energy storage cabinets, and air-conditioning equipment, but not limited thereto.

The aforementioned environmental events include the start time of an environmental event and the end time of an event. For example, the water cutoff information includes the expected start and end time of the water cutoff in the useful electric field. The power outage information includes the expected start and end time of power outage in the useful electric field. The low temperature information includes the expected start and end time when the electric field is affected by the cold air mass.

For some environmental events, such as water cutoff information or power outage information, the processing module 12 selects the first control mode corresponding to the environmental event type corresponding to a predetermined time before the event start time, wherein the predetermined time can be It is 3~6 hours. And the processing module 12 can associate the corresponding environmental event with the operation of each of the loads 22 in the first control mode Send the priority order to a mobile device of the manager or the resident, and notify the manager or the resident of preparation in advance.

When the current time is the event start time, the processing module 12 selects the second control mode corresponding to the environmental event type. And the processing module 12 transmits the corresponding environmental events and the operation priority of each load 22 in the second control mode to the mobile device.

And the processing module 12 transmits the corresponding environmental events and the operation priority of each load in the control mode to the mobile device.

After the mode selection step, enter a control step. In the control step, the control module controls each of the loads 22 to operate according to their respective operation priorities according to the control mode selected by the processing module 12 . The selected control mode (including the operation priority) can be sent to the control module 14 by the processing module 12, or the processing module 12 can mark the currently selected control mode in the database 10 and then notify the control module 14, and the control The module 14 selects the control mode marked by the processing module 12 from the database 10 .

The following examples illustrate different environmental events and the actions of the power control system 1 .

〔Water interruption information〕

Please cooperate with Fig. 3, in the mode selection step, when the processing module 12 judges that the received environmental event meets the water cut-off type, the predetermined time before the event start time (such as 4 hours), select mode 1-1 (first control mode). In the control step, the control module 14 controls each of the loads to operate according to their respective operation priorities according to the mode 1-1, that is, controls the pumping motor of the water tower to be the first priority operation, for example, within 4 hours before the event start time, and lasts The water tower is forced to be filled with water, and the pumping motor of the water tower is not started until a low water level is detected.

When the processing module 12 is the event start time at the current time, in the mode selection step, the processing module 12 selects mode 1-2 (second control mode), and the operation priority of the water tower pumping motor is non-operation or last. In the control step, when the water tower pumping motor or its corresponding detection device 24 sends out an operation request signal, the control module 14 does not control the operation of the water tower pumping motor because the operation priority is non-operation or last. The detection devices 24 corresponding to other loads 22 send out operation request signals, or when other loads 22 send out operation request signals, the control module 14 controls the operation of the loads according to the respective operation priorities of the loads 22 in modes 1-2. .

When the current time is the end time of the event, in the mode selection step, the processing module 12 selects mode 1-3 (the third control mode), because the pumping motor of the water tower is not running during the water failure event, and the water level of the water tower may be low water level. In the control step, the control module 14 allows the pumping motor of the water tower to operate with the first priority according to modes 1-3, so as to replenish water to the water tower.

〔Blackout information〕

Please cooperate with FIG. 3, in the mode selection step, when the processing module 12 judges that the received environmental event meets the type of power outage, at the predetermined time (such as 4 hours) before the event start time, select the mode 2-1 (the first control mode). In the control step, the control module 14 controls each of the loads 22 to operate according to their respective operation priorities according to the mode 2-1, that is, controls the water tower pumping motor and the backup charging energy storage cabinet to be the first priority operation, for example, at the event start time In the previous 4 hours, the water tower was continuously filled with water forcibly, and the backup charging energy storage cabinet was continuously charged to a fully charged state.

When the processing module 12 is the event start time at the current time, in the mode selection step, the processing module 12 selects mode 2-2 (second control mode), and the operation priority of the water tower pumping motor is non-operation or last. In the control step, the control module 14 controls the operation of the loads 22 according to the respective operation priorities of the loads 22 in the mode 2-2, and controls the backup charging energy storage cabinet to supply power to other loads 22 (such as emergency elevators) , emergency lighting).

When the current time is the end time of the event, in the mode selection step, the processing module 12 selects mode 2-3 (the third control mode). In the control step, the control module 14 enables the backup charging energy storage cabinet to operate with the first priority charging according to modes 1-3, so as to supplement the backup power.

In addition, when the grid detection device 42 detects that the grid 20 has no power supply, an environmental event corresponding to abnormal power is generated, and when the processing module 12 receives an environmental event corresponding to abnormal power, the processing module 12 selects mode 2 -2 As the control mode when the power is abnormal, in the control step, the control module 14 controls the operation of the loads 22 according to the respective operation priorities of the loads 22 in the mode 2-2.

When the grid 20 resumes normal power supply, the grid detection device 42 generates an environmental event corresponding to power recovery, and when the processing module 12 receives an environmental event corresponding to power recovery, the processing module 12 selects mode 2-3 as the power recovery In the control mode, in the control step, the control module 14 controls the operation of the loads 22 according to the respective operation priorities of the loads 22 in the mode 2-3.

〔Low Temperature Information〕

Please refer to FIG. 3 , in the mode selection step, when the processing module 12 judges that the received environmental event conforms to the type of low temperature, it selects mode 3 at the event start time. In the control step, the control module 14 controls each of the loads 22 to operate according to their respective operation priorities according to the mode 3, so that the air conditioner can be operated in priority, for example, when the air conditioner corresponding to the heating is detected When the detection device 24 detects that the indoor temperature is too low, it sends an operation request signal, and the control module 14 gives priority to controlling the air conditioner to supply heating.

Each of the above-mentioned control modes may also respond to the occurrence of two environmental events at the same time, and the processing module 12 will also generate a new operating priority order according to the corresponding environmental events; for example, before the water cut-off event begins, The use mode 1-1 makes the pumping motor of the water tower the first priority operation. During the operation of the pumping motor of the water tower, if the processing module 12 receives a new environmental event that is a power outage, the processing module 12 will turn the original water stop Event mode 1-1 (first control mode) The backup charging energy storage cabinet is the second priority operation, adjusted to allow the backup charging energy storage cabinet to be the first priority operation, forming a new control mode corresponding to two environmental events at the same time , and then use the new control mode to control the operation of the load 22 to allow the water tower pumping motor to operate and charge the backup charging energy storage cabinet. Preferably, as long as one of the loads 22 has a higher priority in the two original control modes, the priority of the load 22 in the new control mode is set to the higher priority.

In one embodiment, in the control step, when the control module 14 receives an operation request signal corresponding to any one of the loads 22, the control module 14 determines the load 22 corresponding to the operation request signal When the operation priority is the first priority, the control module 14 controls the operation of the load 22 corresponding to the operation request signal. If the control module 14 judges that the operation priority of the load 22 corresponding to the received operation request signal is the second priority, then when the first priority load 22 is not in operation, the control module 14 then The operation of the load 22 corresponding to the operation request signal is controlled.

For example, within a predetermined time before the start time of the water outage event, the pumping motor of the water tower is the first priority to run. When the water tower reaches the full water level, the pumping motor of the water tower stops running first. At this time, the control module 14 Received spare charging storage cabinet (second priority) When the operation request signal is received, the control module 14 controls the backup charging energy storage cabinet to perform operation because the pumping motor of the lower water tower is not in operation, so that it starts to charge.

In one embodiment, the control module 14 not only controls the operation priority of the load 22 through the operation priority in the load 22 control data, but also the processing module 12 also judges the operation priority in each control mode The regular power consumption of each of the loads 22 is adjusted according to the regular power consumption of each of the loads 22 in each control mode; 4 hours), select mode 1-1 (the first control mode), that is, control the pumping motor of the water tower to be the first priority operation; but when the power consumption of the air conditioner is greater than the threshold value of one of the regular power consumption, it means that at this time Air-conditioning equipment often needs electricity before the water is cut off, so the air-conditioning equipment in mode 1-1 will be adjusted to the first priority instead of the second priority. In this way, the priority order of the loads 22 can be adjusted according to the actual electricity consumption habit of the application electric field.

Referring to FIG. 5 , in a third preferred embodiment of the present invention, it is based on the first embodiment. The power utilization field can also communicate with another power control system 1' of an adjacent power utilization field through the communication network 30, and use the other power control system 1' as another data source. The other power control system 1' can transmit the received environmental events to the processing module 12 of the power control system 1. When the processing module 12 does not receive the environmental event from the data source 40, but receives an environmental event from another power control system 1', the processing module 12 can send an inquiry message to a mobile device of the manager or the resident , ask the management personnel or residents whether they want to use the environmental events transmitted from another power control system 1' as the basis for controlling the load 22, in the management When the management personnel or residents determine to use the environmental events transmitted from another power control system 1', the processing module 12 selects the corresponding control mode according to the environmental events transmitted from another power control system 1', and the control module 14 According to the selection of the corresponding control mode, the operation priority of the load 22 is controlled.
