Abstract:This article starts from the actual conditions of substation production, from principles, methods and design, and describes the substation battery real-time monitoring system。In view of the fact that the state of intelligence in battery maintenance and condition monitoring of existing substation communication equipment rooms is not high, this paper proposes the idea of real-time monitoring system for substation storage batteries based on the Internet of Things technology, and realizes real-time monitoring of battery cells in the communication room of the station through the sensor network. Through remote login, the operation and maintenance personnel can view the status of the battery in the station in real time and improve the maintenance efficiency.
