Design and Implementation of Underground Gas Safety Detection System Based on Single Chip Microcomputer
Abstract
In the underground working environment, abnormal temperature and excessive concentrations of gases such as methane and CO ₂ are important hidden dangers that can cause safety accidents, which may lead to serious consequences such as explosions and poisoning, threatening the life safety of miners and the production safety of mines. Therefore, it is necessary to develop a safety detection system that can monitor underground environmental parameters in real time and accurately.
This design proposes an underground gas safety detection system based on STM32F103C8T6 microcontroller. The main functions of the system include: detecting the temperature of the current underground environment through DS18B20 temperature sensor; Using MQ-4 sensors to detect methane concentration in the environment; Detecting the concentration of CO ₂ in the environment through SGP30 sensor; Real time acquisition of underground environmental images using SXT cameras; Visually display temperature, methane, and CO ₂ detection data through OLED display screens; At the same time, the system transmits the detected data to the mobile phone through the ECBO2 Bluetooth module, achieving remote monitoring.
The function of the underground gas safety detection system is to provide a comprehensive and convenient safety monitoring tool for underground operations. By real-time monitoring of environmental parameters and remote transmission of data, it can help management personnel to timely grasp the safety situation underground, facilitate quick measures to be taken when abnormalities are detected, reduce the risk of safety accidents, and ensure the safety of underground operations.
