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.
