Design and Realization of Electrical Energy Real-time Distant Monitoring and Control System

It combined ZigBee wireless sensor network,MQTT message broker and WebSocket technology together to realize a real-time distant monitoring and controlling system w hich is suitable for both family and industrial zones.This system can reduce unnecessary w aste of electricity and save manpow er effectively.The ZigBee w ireless sensor netw ork is used to collect the electricity information in the background.Furthermore,the intermediate layer utilizes MQTT message broker to manage the collected information of electricity and reserves a connector for user to create new information so that the system is easy to expand.In addition,the front end enhances the generality through B/S mode and increases the instantaneity by utilizing WebSocket to push the information received by Web server to the client brow ser.The result show s that this system has improvement in expandability,generality and real-time performance.
