Traditional drunk driving detection relies on manual inspection, which has problems such as low efficiency, strong subjectivity, and difficulty in real-time intervention, and cannot meet the requirements of modern traffic management for safety and timeliness.The driver drunk driving detection and control system based on STC89C52 single-chip microcomputer integrates infrared obstacle avoidance tubes, DS1302 clock module, MQ-3 alcohol sensor, buttons, LCD1602 display screen and ECB02 Bluetooth module to realize functions such as driving seat occupancy detection, alcohol concentration monitoring, automatic intervention and remote control. The core functions of the system include: detecting whether there is a person in the drivers seat through an infrared obstacle avoidance tube; obtaining the current time with the help of the DS1302 clock module, which supports time correction through buttons; setting the upper limit of alcohol content through buttons (20-80mg/100ml is the drinking range, 80mg/100ml is the drunk range); using MQ-3 to detect alcohol value. When it is detected that there is a person in the main drivers seat and the alcohol content is higher than the set value, the vehicle will automatically decelerate to a stop. At this time, the mobile phone cannot control the operation, and the sound and light alarm frequency is different in the drinking and drunk states; the LCD1602 display screen displays the current time and alcohol content in real time; the normal operation of the car can be controlled through the mobile phone terminal via the Bluetooth module.The implementation of this system has effectively improved the automation and intelligence level of drunk driving detection and intervention. Through real-time monitoring, automatic intervention, graded alarm and Bluetooth control, it provides a convenient and efficient solution for drunk driving prevention and control. At the same time, it provides a reference for the development of the intelligent field of traffic safety equipment, and has high practical value and promotion significance.Keywords:STC89C52; Driver Drunk Driving Detection and Control System; Sensor Monitoring; Bluetooth Control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1.2.1 国外研究现状1.2.2 国内研究现状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 红外避障管选择2.1.3 时钟模块选择2.1.4 酒精传感器选择2.1.5 显示模块选择2.1.6 蓝牙模块选择2.1.7 按键模块选择2.1.8 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 红外检测电路3.3 时钟模块电路3.4 酒精检测电路3.5 显示模块电路3.6 蓝牙通信模块电路3.7 按键模块电路3.8 声光报警电路3.9 电机控制电路第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 LCD1602显示模块子流程设计4.4 独立按键子流程设计4.5 时钟模块子流程设计4.6 ADC模数转换子流程设计4.7 直流电机速度调节子流程设计4.8 蓝牙模块子流程设计第 5 章 实物测试5.1 整体实物测试5.2 红外检测功能测试5.3 时钟与按键设置功能测试5.4 酒精检测与声光报警功能测试5.5 显示功能测试5.6 蓝牙通信与电机控制功能测试5.7 系统综合运行测试第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
