摘　　要：酒后驾驶容易引发交通事故,对生命财产安全构成极大的威胁。针对此问题,本研究基于STM32单片机设计了一种能够防止酒后驾驶的车载智能酒精锁系统。系统首先使用高灵敏度酒精传感器验证酒精检测的灵敏性和准确性,后根据检测结果进行判断并相应动作。本系统的设计创新点在于采用集成化设计、多模态反馈、远程通知功能、低功耗设计,提高了系统的便捷性和实用性。通过对系统进行不同酒精浓度的多组测试,测试结果表明本系统能够进行较为准确的酒精浓度判断,系统动作具有一定的可靠性,对预防酒驾起着重要的作用。Drunk driving is easy to cause traffic accidents and poses a great threat to life and property safety. To solve this problem, this study designed a vehicle intelligent alcohol lock system based on STM32 microcontroller to prevent drunk driving. The system first uses a high-sensitivity alcohol sensor to verify the sensitivity and accuracy of alcohol detection, and then judges and acts accordingly according to the detection results. The design innovation of this system lies in the use of integrated design, multi-modal feedback, remote notification function, and low-power design, which improves the convenience and practicability of the system. Through the multi-group test of different alcohol concentrations, the test results show that the system can judge the alcohol concentration more accurately, and the system action has certain reliability in preventing drunk driving plays an important role.
