Design of monitoring and control system for intelligent micro-circuit breaker based on Internet of Things technology

With the construction of the novel power system, the intelligent electrical equipment industry is booming. Aiming at the monitoring and control problem of micro-circuit breakers, this paper analyzes the interactive mode and implementation scheme of the visual platform and hardware equipment and determines the development scheme based on the ESP32 microcontroller (MCU) + MQTT transmission protocol + OneNET—China Mobile Internet of Things open platform. In this scheme, ESP32 is used as the central controller of the system, and the collected equipment parameters are transmitted to the OneNET cloud platform. With the help of the cloud platform’s data visualization view, the intelligent micro-circuit breaker interface is used to detect the equipment working parameters and remotely control the opening and closing.
