Abstract
This design mainly uses Internet of Things technology to upgrade and transform the environmental monitoring system of the power transformation and distribution station. The sensing layer uses temperature and humidity sensors, water level sensors, and smoke sensors. The application layer consists of control modules such as fans, water pumps, temperature and humidity, and alarms. The actions of the executing components are controlled by the STM32 chip. The network layer packages the collected information into data packets based on the MQTT communication protocol of TCP/IP. The ESP8266 wireless Wi Fi module transmits the data packets to the Alibaba Cloud ECS server, which publishes the data packets to WeChat applets. Users can use a WeChat applet to monitor the ambient temperature and humidity values, smoke concentration, water level information, and the status of alarms, fans, and pumps in the power distribution room at any time. When the alarm conditions are met, the terminal will automatically turn on the corresponding control equipment, and can also independently and remotely control the operation of the equipment through WeChat applets, which better solves the problem of manual inspection and low efficiency in traditional power transformation and distribution stations.
