Electricity Distribution network intelligent feeder terminal unit (FTU) is an important facility to control and monitor the operating state of the power distribution system.To provide effective grid monitoring data, power companies need to collect data from FTUs and upload it to the operation center in real time, thus requiring a reliable and stable wireless network connection.

The deployment environment of distribution network facilities has harsh weather conditions such as cold, high temperature, and humidity. Ordinary networking devices cannot operate stably and reliably for a long time in such harsh environments. Therefore, industrial-grade networking devices need to be introduced.

There are a large number of FTUs deployed in scattered locations. When a fault occurs, traditional methods require power maintenance personnel to troubleshoot multiple fault terminals, resulting in low maintenance efficiency and long power outage time.In order to improve maintenance efficiency, the gateway needs to timely report the fault alarm information, which is convenient for maintenance personnel to quickly locate and troubleshoot the fault.
