AI Technical Summary

Technical Problem

In existing technologies, monitoring the communication status of feeder terminals in power distribution systems relies on log analysis from the power supply master station and general network packet capture tools. This is cumbersome to operate and lacks real-time monitoring and intelligent analysis tools, resulting in high maintenance difficulty and low fault diagnosis efficiency.

Method used

Design an offline analysis device connected in series between the feeder terminal and the communication module. It includes a main control board, a gateway module, and a restart module. It can monitor the communication status in real time and perform fault diagnosis by automatically switching the connection mode and restarting the module, thereby improving the degree of automation.

Benefits of technology

It enables real-time monitoring and fault diagnosis of communication data between feeder terminals and communication modules, improving the efficiency of fault diagnosis and the system's self-healing capability, and enhancing the reliability and ease of operation and maintenance of the power distribution system.
