The control module 11 can be electrically connected to the plurality of switching modules 10 and the power supply terminal 2. The control module 11 can pre-store a preset current value 110 (for example, 300 amps (A)).

Therefore, during the operation of the selective current distribution device 1 of the present invention, the control module 11 can randomly turn on one of the switching modules 10 according to a preset program, so that one of the switching modules 10 will supply the power supply terminal 2 The current is supplied to the load terminal 3.

When the current value is set to 110, the control module 11 turns off the switching module 10 to turn it from the on state to the off state, thereby preventing the supply current from being in a saturated state or a load state. .

Further, when the other switching module 10 is in an on state, the control module 11 detects the current supplied by the power supply terminal 2 to generate a second current supply value 112; and, in the control module 11, determines the second When the current supply value 112 is greater than or equal to the preset current value 110, the control module 11 drives the other switching module 10 from the on state to the off state.

That is, when the second current supply value 112 obtained by the control module 11 is 300 A or more than 300 A, the second current supply value 112 is equal to or greater than the preset current value 110, that is, the current supply current. The quantity is in a saturated state or a load state. At this time, the control module 11 turns off the other switching module 10 to turn the other switching module 10 from the on state to the off state.

However, it is worth mentioning that, in this embodiment, the control module 11 can be electrically connected to at least one external signal source 4, and is controlled when the control module 11 receives the supply signal 40 transmitted by at least one external signal source 4. The module 11 drives the switching module 10 in the on state to be in an off state.

Specifically, the control module 11 of the present invention can also be electrically connected to at least one external signal source 4, such as a building control center, a remote control center of the security system, or a building disaster prevention monitoring system. Therefore, at the time of the accident, at least one external signal source 4 sends the supply signal 40 to the control module 11. At this time, the control module 11 turns off the switching module 10 in the on state according to the supply signal 40. It is disconnected for power saving, allowing the generator to supply the rest of the power to other utilities or households.

Therefore, the selective current distribution device 1 of the present invention can effectively control the supply and output of the emergency power supply when a power outage or an accident occurs in the building, thereby enabling the emergency power supply to be maximized to improve the convenience of the power supply control. Sex.

In addition, the control module 11 can be electrically connected to at least one external signal source 4. When the control module 11 receives the supply signal 40 transmitted by at least one external signal source 4, the control module 11 drives the other switching module 10 to The conduction state is turned to the off state. That is to say, after the control module 11 receives the supply signal 40, only one switching module 10 can be left in the on state, and all the remaining switching modules 10 are disconnected, and the remaining switching module is left. 10 may be determined by the operator or the control module 11 built-in program.

When the power is supplied to the load terminal 3, the processing unit 11B drives the detecting unit 11A to detect the current supplied by the power supply terminal 2 to generate the first current supply value 111. When the processing unit 11B determines that the first current supply value 111 is smaller than the preset current value 110, the processing unit 11B can randomly drive the other switching module 10 to be in a conducting state, so that the other switching module 10 supplies power. To load terminal 3.

For example, the control module 11 of the present invention may further include a detecting unit 11A and a processing unit 11B.

When the processing unit 11B receives the supply signal 40 sent by the building control center, the remote control center of the security system, or the building disaster prevention monitoring system, the processing unit 11B can close all the switching modules 10 in the on state. It is turned off to perform power saving operation, or only one switching module 10 is left in an on state, and the remaining switching modules 10 are all disconnected.

Further, when the other switching module 10 is in the on state, the processing unit 11B drives the detecting unit 11A to detect the current supplied by the power supply terminal 2 to generate the second current supply value 112; and, in the processing unit 11B When it is determined that the second current supply value 112 is less than the preset current value 110, the processing unit 11B can randomly drive the other switching module 10 to be in a conducting state, so that the further switching module 10 supplies power to the load terminal 3.

That is, while the other switching module 10 is turned on and supplies current to the other load terminal 3, the processing unit 11B drives the detecting unit 11A to detect the current amount of current supplied by the power supply terminal 2, and generates a second current.

Next, the processing unit 11B determines whether the second current supply value 112 is less than the preset current value 110. If the second current supply value 112 is 150 A, the processing unit 11B determines that the second current supply value 112 is less than the preset current value 110. Then, a switching module 10 is turned on again to supply current to the other load terminals 3.

Further, when the other switching module 10 is in the on state, the processing unit 11B drives the detecting unit 11A to detect the current supplied by the power supply terminal 2 to generate the second current supply value 112; and, in the processing unit 11B When it is determined that the second current supply value 112 is greater than or equal to the preset current value 110, the processing unit 11B drives the other switching module 10 to be turned from the on state to the off state. That is, when the processing unit 11B obtains the second current supply value 112 obtained by the detecting unit 11A and the current value 112 is 300 A or more, it indicates that the second current supply value 112 is equal to or greater than the preset current value 110, that is, the current The supply current amount is in a saturated state or a load state.
