Real-time monitoring of underground environmental parameters and timely early warning are of great significance for ensuring the safety of miners lives and preventing accidents. Traditional mine safety monitoring methods have problems such as limited coverage, delayed response, and untimely data feedback, which are difficult to meet the safety management needs of complex underground environments.​The design of the mine safety helmet based on the STM32F103C8T6 microcontroller integrates DHT11 temperature and humidity sensors, MQ-4 methane sensors, MQ-135 harmful gas sensors, 5516 photoresistors, GPSBeidou positioning modules, 3 independent buttons, OLED displays, AIR7804G modules, sound and light alarm devices, lighting equipment, etc., realizing real-time monitoring, automatic early warning, positioning and tracking, and remote data transmission of the mine environment. The core functions of the system include: real-time monitoring of temperature and humidity through DHT11, triggering sound and light alarms when the values exceed the set range; detecting methane concentration with MQ-4, activating sound and light alarms when the concentration exceeds the standard; monitoring harmful gas concentration with MQ-135, issuing sound and light warnings when exceeding the standard; obtaining light values through 5516 photoresistors, automatically turning on the lights when below the threshold, and supporting button manual control of lighting; obtaining real-time latitude and longitude through GPSBeidou modules to realize personnel positioning; supporting button setting of various parameter thresholds; real-time display of monitoring data, positioning information and equipment status through OLED display; transmitting data to the mobile phone through AIR7804G module, supporting mobile phone setting of thresholds and remote monitoring.​The implementation of this design effectively improves the real-time and intelligent level of mine safety monitoring, provides active safety protection for underground workers, reduces the risk of safety accidents, and provides accurate data support for mine safety management, which has high practical application value and promotion significance.​Keywords:STM32F103C8T6; Mine safety helmet; Environmental monitoring; Positioning and tracking; Sound and light alarm; 4G communication​目录第 1 章 绪论1.1 研究的目的及意义1.2 国内外发展情况1.3 本文主要研究内容第2章 设计思路与方案论证2.1 主要元器件选择2.1.1 主控芯片选择2.1.2 温湿度传感器选择2.1.3 甲烷传感器选择2.1.4 有害气体传感器选择2.1.5 光照检测模块选择2.1.6 定位模块选择2.1.7 按键模块选择2.1.8 显示模块选择2.1.9 4G 模块选择2.1.10 声光报警模块选择2.2整体设计方案第 3 章 硬件设计3.1 主控电路模块3.2 温湿度传感器电路3.3 甲烷传感器电路3.4 有害气体传感器电路3.5 光照检测模块电路3.6 GPS 北斗定位模块电路3.7 显示模块电路3.8 4G 模块电路3.9 按键模块电路3.10 声光报警与照明设备驱动电路第4章 系统程序设计4.1 编程软件介绍4.2 系统主流程设计4.3 独立按键4.4 OLED显示流程设计4.5 温湿度检测模块子流程4.6 4G模块联网子流程设计4.7 ADC模数转换子流程设计4.8 GPS模块子流程设计第 5 章 实物测试5.1 整体实物测试5.2 温湿度传感器功能测试5.3 甲烷传感器功能测试5.4 有害气体传感器功能测试5.5 光照检测模块功能测试5.6 GPS 北斗定位模块功能测试5.7 4G 模块功能测试5.8 按键设置与显示功能测试5.9 声光报警模块功能测试第 6 章 总结与展望6.1 总结6.2 展望致谢参考文献附录附录一原理图附录二PCB附录三主程序
