Research and application of a new edge computing DTU device

The traditional DTU terminal only supports the professional application of distribution automation, which is not suitable for the requirements of topology discovery, line loss lean analysis, remote equipment management, new scene business and so on. The device does not have the ability of plug and play, edge computing, comprehensive state perception, terminal software definable, etc., which can not meet the current development and construction needs of distribution Internet of things technology. The common unit hardware is based on edge computing core board, the software is based on embedded operating system and docker container technology, the spacer unit is based on dual system core board, and the software is based on real-time and non real-time operating system. It integrates the functions of telemetry, remote signaling, remote control, protection and communication, and is widely used in distribution room, highvoltage cabinet and ring main unit It can realize the basic data and dynamic information sharing, resource integration, accurate control and intelligent decision-making of power supply equipment in multi loop centralized monitoring applications such as substation, switching station, etc., and cooperate with the distribution electronic station and master station to realize the distribution network automation functions such as operation status monitoring, fault identification, fault isolation and power supply recovery in non fault areas.
