[0072] Specifically, the processor (32-bit MCU HC32F460PETB) itself does not have a network interface, and needs to achieve network communication through other peripheral conversion methods. The network protocol unit can use the W5500 chip, which is used to interconnect with the processor through the SPI interface.

[0073] As an optional embodiment, the smart power distribution equipment and the camera can be located in the same network segment and use the ICMP protocol to detect the network status of the camera. When it is detected that the camera network is offline, the smart power distribution equipment generates an alarm message and transmits it to the corresponding platform; when the smart power distribution equipment and the front-end camera are offline at the same time and the upper-level distribution network does not receive the power off alarm message, the upper-level distribution network automatically generates a network off alarm.

[0074] Optionally, the intelligent power distribution equipment detects the working condition of the power supply through the neutral wire and the live wire connected in series, and performs corresponding protection actions when undervoltage, overvoltage, overcurrent, or leakage occurs, disconnects the back-end equipment, and protects the power safety of the back-end equipment; when the power supply returns to normal, the intelligent power distribution equipment automatically connects to the back-end equipment and powers on the back-end equipment again;
