Abstract: A communication power supply system includes an alternating current power distribution module, a rectifier module, a monitoring module, a direct current power distribution module, and a signal-driven collection board. The monitoring module sends a control signal to the direct current power distribution module by using the signal-driven collection board, where the control signal is used to control the closing or opening of a circuit in the direct current power distribution module. The communication power supply system uses the monitoring module to control the direct current power distribution module, to control whether to power on the loads connected to the direct current power distribution module.

Abstract: A power distribution system includes a backplane communication busbar and a circuit breaker. The backplane communication busbar includes at least one slot, and a first interface is configured in each slot. Each first interface is connected to a first resistor R1 having a different resistance value. A second interface of each circuit breaker is connected to a second resistor R2, and when the second interface of the circuit breaker is plugged in any first interface, a preset voltage interval corresponding to a resistance value of the first resistor R1 is uniquely determined by using a series circuit including the first resistor R1 and the second resistor R2.

Abstract: The control apparatus includes an electrical signal detection unit, a control unit, a contactor, a first execution unit, a protection unit, and a second execution unit. The electrical signal detection unit detects an electrical signal on a loop, and send the electrical signal to the control unit. The control unit generates a control signal, and send the control signal to the first execution unit. The contactor is connected to the loop. The first execution unit controls the contactor to be closed or opened, where when the contactor is closed, the loop is connected, and when the contactor is opened, the loop is disconnected. The protection unit detects a current value on the loop when the contactor is closed, where an opening instruction is sent to the second execution unit when the current value reaches a trip threshold. The second execution unit opens the contactor when receiving the opening instruction.
