In the context of the strategic goal of building energy Internet, State Grid Corporation of China has established a crossdisciplinary joint construction and common Internet of Things management platform, which carries out standardized access and unified online control for equipment in transmission, power transformation, distribution and other fields. In order to improve the access debugging efficiency of the IoT management platform accessed by terminal devices, this paper designed a full-scene simulation detection system for the intelligent IoT system oriented to the energy Internet. By using the existing construction ideas of intelligent IoT system and following the complete architecture of "cloud, tube, edge, terminal ", the construction method of the simulation and coordination platform of intelligent IoT system of "information-physical coupling" is realized. Advanced technologies such as micro-service and distribution are adopted to build a lightweight simulation test system. A small amount of server resources can be used to simulate and test whether the communication protocol of the side device supports the communication protocol requirements of the intelligent IoT management platform. The functions of reporting equipment data collection and issuing control commands are tested, so as to complete the simulation, verification and testing functions of the whole electric power industry chain intelligent IoT system covering both internal and external businesses, and provide technical support for the construction and promotion of the IoT management platform of State Grid Corporation of China. Combined with the whole scene simulation and detection system of the intelligent Internet of Things system, the operating state sensing monitoring scene of the power distribution area is built to verify the functions of data reporting of the fusion terminal and command issuing of the simulation and detection system.
