Traditional rescue helmets can only provide basic protection, lacking real-time perception and intelligent response capabilities to environmental parameters and human status, making it difficult to meet the safety requirements in high-risk rescue scenarios.​The intelligent emergency rescue helmet system based on STM32F103C8T6 single-chip microcomputer integrates hardware such as MQ-135 harmful gas sensor, MLX90614 temperature detection module, heart rate detection module, GPS positioning module, photoresistor, MPU6050 attitude sensor, ultrasonic module, buttons, OLED display and GSM module, and realizes several core functions: detecting the concentration of harmful gases in the environment through MQ-135; real-time obtaining the users body temperature and heart rate with the help of MLX90614 and heart rate detection module; acquiring the current positions longitude and latitude by GPS module; monitoring ambient light through photoresistor, and automatically turning on the lighting when the light is low; detecting whether the user falls through MPU6050, and triggering the GSM module to send a distress SMS if the user does not get up 30 seconds after falling; using the ultrasonic module to detect oncoming vehicles from behind and displaying Vehicles approaching from behind on the OLED; setting the minimum light threshold and manually sending distress SMS through buttons; the OLED display shows various measurement data and system status in real time.​The realization of this system has significantly improved the intelligence level of emergency rescue helmets, realized comprehensive real-time monitoring, active early warning and rapid rescue of the environment and physical status of rescuers, provided multiple guarantees for the life safety of rescuers, and also provided accurate on-site information for emergency rescue command, which has important practical application value and promotion prospects.Keywords:STM32F103C8T6; Intelligent emergency rescue helmet; Multi-parameter monitoring; Fall detection; GPS positioning; OLED display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 有害气体检测模块选择2.1.3 体温检测模块选择2.1.4 心率检测模块选择2.1.5 GPS 定位模块选择2.1.6 光照检测与照明模块选择2.1.7 跌倒检测模块选择2.1.8 超声波模块选择2.1.9 显示与按键模块选择2.1.10 短信发送模块选择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 有害气体检测模块电路3.3 体温与心率检测模块电路3.4 GPS 定位模块电路3.5 光照检测与照明模块电路3.6 跌倒检测模块电路3.7 超声波模块电路3.8 按键与显示模块电路3.9 4G 通信模块电路第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 ADC模数转换子流程设计4.6 红外测温模块子流程设计4.7 心率血氧模块子流程设计4.8 GPS模块子流程设计4.9 MPU6050模块子流程设计4.10 超声波检测模块子流程设计第 5 章 实物测试5.1 整体实物测试5.2 有害气体检测模块功能测试5.3 体温与心率检测模块功能测试5.4 4G通信模块功能测试5.5 光照检测与照明模块功能测试5.6 跌倒检测模块功能测试5.7 超声波与按键模块功能测试第 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
