Smart monitoring of distribution room is an important means to improve the lean management level of low-voltage distribution network. Aiming at the problems of diversity of bottom terminal interface, difference of communication protocol and poor real-time of business processing in current comprehensive monitoring of distribution room, based on the research of key technologies such as plug and play interface design, localized edge computing and virtual container deployment, a general edge IOT agent device for comprehensive monitoring of distribution room is designed, and the module of edge IOT agent device is given Based on cloud edge collaboration, the architecture and function design of the comprehensive monitoring system for the distribution room are proposed. The accuracy, reliability and real-time performance of the data monitoring for the distribution room are effectively improved, which is a good example Typical experience accumulation of smart IOT system in application scenarios of distribution station area.
