Design of Adaptive Power Distribution Protocol Conversion System based on MQTT Cloud Edge Interaction

Abstract

With the rapid development of the power Internet of Things, more and more intelligent terminals in the power scene need to interact with users for information. Building a standard information physical model to realize the unified access of multi-source and heterogeneous terminals is a major problem faced by the construction of the electric Internet of Things. Based on MQTT's good adaptability to the Internet of Things and Docker's cross-platform, this paper designs a system for adaptive conversion of power distribution protocol based on the Internet of Things management platform. Firstly, the frame structure of distribution specification is analyzed and the process of protocol adaptive recognition and analysis adopted by the system is explained. Then, it describes the interaction function of the cloud controller and the side controller docking Roma platform and Docker engine, analyzes the call method of Roma platform based on HPPTS protocol to the north API and Docker API, and explains the Pub/Sub model based on MQTT protocol. And how the platform and devices communicate based on a custom Topic. The cloud edge interaction between controller and controller completes the interface call and system implementation of adaptive protocol transformation. It has completed the test and verification of the adaptive conversion system of power distribution protocol in Hunan Communication Laboratory, which provides an open IoT platform for the power IoT system of Hunan Province, and provides important guidance for the construction of a set of intelligent cloud edge system in Hunan Province. It is of great significance for the construction and promotion of the power IoT system of Hunan Province.
