Design of Remote Control Inverter Based on MQTT Communication Protocol

With the rapid development of the Internet of Things, remote intelligent control has become an inevitable trend in the field of industrial development. To solve the problems of complicated wiring of the inverter monitoring system, insufficiently advanced system architecture, and insufficient message push efficiency, this paper proposes a communication protocol based on Message Queuing Telemetry Transport (MQTT) on the ESP8266 hardware module. The PC terminal starts the MQTT cloud server and subscribes messages to the MQTT cloud server as an MQTT communication client. Once the PC terminal publishes real-time messages to the MQTT cloud server, information exchange between the two parties can be realized and the inverter can be remotely controlled. The upper computer adopts a QT design, and the ID of the slave station can be set at any time to achieve the purpose of real-time control for different slave station inverters. To monitor the operating status of the inverter at any time, facilitate improvement of quality of information transmission, and realize the industrial Internet of Things, this article uses MQTT wireless monitoring of the inverter to achieve the purpose of alarm monitoring.
