Substation Indoor Environment Monitoring System based on STM32

Abstract

Aiming at the problems of low efficiency of manual monitoring of indoor environment in substation, untimely abnormal response and lack of intelligent control of equipment operation environment, an indoor environment monitoring system of substation based on STM32 single chip microcomputer is designed. The system takes STM32F103C8T6 as the main control core, integrates temperature and humidity, smoke, harmful gas, water leakage detection and other types of sensors, realizes real-time acquisition of environmental parameters, local display, over-limit alarm and remote data transmission functions, and adapts to the strong electromagnetic working environment of substation through anti-interference design. The test results show that the system has stable operation, high data acquisition accuracy and timely alarm response, which can effectively ensure the safe and stable operation of substation indoor equipment and improve the intelligent level of substation environmental management.
