According to the operation state of the power distribution equipment 20, the power distribution equipment 20 is controlled to transmit the power supply signal output by the power supply 10 in the power supply link to the ground screen 30.
In the present embodiment, for each power supply link, the power source 10 in the power supply link is connected to each power distribution device 20 in the power supply link. The ground screen 30 is connected to one power distribution device 20 in each power supply link, i.e. there is one power distribution device 20 connected to the ground screen 30 per power supply link to supply power to the ground screen 30.

When the operating state of the distribution equipment a is a normal state and the operating state of the distribution equipment a is a normal state, the distribution equipment a can respectively transmit the power supply signal output by the power supply 1 to the ground screen 1 and the ground screen 2, the distribution equipment a can respectively transmit the power supply signal output by the power supply 2 to the ground screen 1 and the ground screen 2, namely, the link 1 and the link 2 respectively supply power to the ground screen 1 and the ground screen 2. When the operation state of the power distribution equipment A is an abnormal state and the operation state of the power distribution equipment a is a normal state, the power distribution equipment A is controlled to stop transmitting the power supply signal to the ground screen 1 and the ground screen 2, and at the moment, the ground screen 1 and the ground screen 2 are only supplied with power by the link 2.

According to the running state of the power distribution equipment 20 in each power supply link, the power distribution equipment 20 is controlled to supply power to the ground screen 30 by using the power supply 10, so that at least one power supply link supplies power to the ground screen 30, the problem that the power supply reliability is low due to the fact that a single power supply 10 supplies power is avoided, the power supply reliability is improved, the normal display of the ground screen 30 is guaranteed, and the normal operation of activities is guaranteed.

For example, the power of the first-stage power distribution cabinet 21 is 300KW, the power of the second-stage power distribution cabinet 22 is 100KW, and the power of the third-stage power distribution cabinet 23 is 20 KW.
In this embodiment, for each one-level power distribution cabinet 21 in the power supply link, each branch corresponding to this one-level power distribution cabinet 21 is determined, that is, this one-level power distribution cabinet 21, a secondary power distribution cabinet 22 connected to this one-level power distribution cabinet 21, and a tertiary power distribution cabinet 23 connected to this secondary power distribution cabinet 22 are used as a branch of this one-level power distribution cabinet 21.

And taking the power distribution cabinet with the abnormal operation state as a fault power distribution cabinet. Because the operating state of the low-level power distribution cabinet can be influenced by the operating state of the high-level power distribution cabinet, that is, the operating state of the power distribution cabinet located at the downstream side is influenced by the operating state of the power distribution cabinet located at the upstream side, for example, when the second-level power distribution cabinet 22 abnormally stops operating, the operating state of the third-level power distribution cabinet 23 connected to the second-level power distribution cabinet 22 can also be an abnormal state. Therefore, in order to improve the efficiency of fault resolution, after the fault power distribution cabinet is obtained, the branch circuit where each fault power distribution cabinet is located is determined, so that the fault branch circuit is obtained.

And the control module 110 is configured to determine an operating state corresponding to the power distribution device 20 according to the monitoring signal corresponding to the power distribution device 20.
Specifically, each power distribution device 20 is connected to a first monitoring device, and the first monitoring device collects a monitoring signal of the power distribution device 20 connected thereto and sends the monitoring signal to the control module 110. When determining that the signal value corresponding to the monitoring signal is in the first preset value range, the control module 110 determines that the operating state corresponding to the power distribution device 20 is a normal state. When it is determined that the signal value corresponding to the monitoring signal is not within the first preset value range, it is determined that the operating state corresponding to the power distribution device 20 is an abnormal state.
The first monitoring device comprises a voltage sensor, a current sensor and other detection devices. When the first monitoring device is a voltage sensor, the monitoring signal is a voltage signal, and when it is determined that the voltage value corresponding to the voltage signal is in the first preset value range, it is determined that the operating state of the power distribution device 20 connected to the voltage sensor is a normal state.

Alternatively, the first switch 40, the second switch 50, the third switch 60, and the fourth switch 70 may be relays.
It is understood that for each power distribution device 20, the number of that power distribution device 20 is bound to the number of the first monitoring device connected to that power distribution device 20. The operating state of the respective power distribution device 20 is therefore determined from the monitoring signals that can be detected by the first monitoring device. Correspondingly, the number of each power distribution cabinet is bound with the number of the first monitoring device connected with the power distribution cabinet.
Optionally, when the operating state of the power distribution cabinet is determined to be an abnormal state, the alarm information corresponding to the power distribution cabinet is output to give an alarm, so that related personnel can maintain the power distribution cabinet in time.
