Traditional driving safety relies on the drivers own vigilance, which has problems such as delayed response and insufficient risk prediction, making it difficult to fully ensure driving safety.​The wheel safety driving early warning system based on the STM32F103C8T6 microcontroller integrates an infrared speed measurement module, an ultrasonic ranging module, a heart rate and blood oxygen module, an MQ-7 carbon monoxide sensor, an SGP30 carbon dioxide sensor, an alcohol detection module, a one-key alarm button, buttons, an OLED display, and a 4G module, etc., realizing multi-dimensional safety monitoring and intelligent early warning during vehicle driving. The core functions of the system include: detecting the speed of the elderly car through the infrared speed measurement module; measuring the distance of obstacles in front of the car with the ultrasonic ranging module. If the distance is greater than the set maximum value, the green light is on; if the distance is between the set upper and lower limits, the yellow light is on, and if the speed is not zero, the voice reminds Dangerous, pay attention to deceleration; if the distance is less than the set minimum value, it brakes directly; using the heart rate and blood oxygen module to detect the drivers heart rate and blood oxygen, and if the heart rate or blood oxygen is higher or lower than the set value, an acousto-optic alarm is given; monitoring the CO in the car through MQ-7, and ventilating when the CO is greater than the set maximum value; monitoring the CO₂ in the car through SGP30, and ventilating when the CO₂ is greater than the set maximum value; when the alcohol detection module detects that the current users alcohol concentration is greater than the set maximum value, it automatically locks the car and sends a text message reminder to the mobile phone; there is a one-key alarm button in the car, which can call for help from family members; supporting the setting of various thresholds through buttons; displaying data through the OLED display; and remotely sending data to the mobile phone through the 4G module to realize remote monitoring.​The implementation of this system has effectively improved the safety and intelligence level of vehicle driving, monitored driving risks in multiple dimensions and given timely warnings, provided a reliable guarantee for the safe driving of elderly cars and other vehicles, and also provided a reference for the research and development of similar vehicle safety early warning equipment, with high practical application value.Keywords:STM32F103C8T6; Wheel safety; Driving early warning; Sensor; Intelligent monitoring; 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 红外测速模块选择2.1.3 超声波测距模块选择2.1.4 心率血氧模块选择2.1.5 气体传感器选择2.1.6 酒精检测模块选择2.1.7 4G 模块选择2.1.8 显示与按键模块选择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 红外测速模块电路3.3 超声波测距模块电路3.4 心率血氧模块电路3.5 气体传感器电路3.6 酒精检测模块电路3.7 4G 模块电路3.8 显示与按键模块电路第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 直流电机速度调节子流程设计4.7 SGP30模块子流程设计4.8 心率血氧模块子流程设计4.9 超声波检测模块子流程设计4.10 语音播报模块子流程设计4.11 4G模块联网子流程设计第 5 章 实物测试5.1 整体实物测试5.2 红外测速模块功能测试5.3 超声波测距模块功能测试5.4 心率血氧模块功能测试5.5 气体传感器功能测试5.6 酒精检测模块功能测试5.7 4G 模块功能测试5.8 显示与按键功能测试第 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
