Research on cloud-side communication mapping of the distribution internet of things based on MQTT protocol

There are problems in the distribution Internet of Things (D-IoT), such as difficult maintenance, weak monitoring and poor interoperability of devices. Based on IEC 61850, the information model and information exchange method of Intelligent Electronic Devices (IEDs) are standardized. This can realize the interconnection, intercommunication, plug and play and data fusion of devices. This paper analyzes the communication scenarios and requirements between a cloud master station and edge devices in the D-IoT, studies the implementation method of IEC 61850 abstract communication service mapping based on the lightweight MQTT (Message Queuing Telemetry Transport) communication protocol, and establishes a subset of IEC 61850 communication for information interaction between the cloud master station and edge devices. A test platform is built, and the feasibility of the mapping method is verified through functional and performance experiments. The communication mapping of IEC 61850 based on MQTT can realize the interconnection and intercommunication of the cloud master station and edge devices in the D-IoT.This work is supported by the National Key Research and Development Project of China (No. 2016YFB0900600), the Science and Technology of State Grid Corporation of China (No. 52094017000W), and Key Research and Development Program of Shandong Province (No. 2019GGX103019).
