基于AT89S51单片机的酒后驾车报警系统设计

针对汽车驾驶员酒后驾车可能导致人身财产损失等问题,提出设计一种汽车安全驾车报警系统.该系统主要利用酒精传感器探测酒精含量是否超标,并结合AT89S51单片机等设计出.主要功能是通过控制系统对发动机启动上锁,每次当驾驶员启动发动机前必须先对着吹气管吹气,系统检测驾驶员酒精含量是否超标,如果不超标将立刻对发动机启动解锁,如果超标将立刻发出声音警告并继续保持发动机启动上锁.文中通过Protes对设计的系统进行仿真分析.仿真实验结果有效地显示和验证了此设计的合理性和可行性.

Design of Drunken Driving Alarm System Based on AT89S51

Car drivers often drive on drunken. It may loss property. A car driving alarm system under drunk driving is designed. Alcohol sensor is used to detect whether the diver drank. It combines with AT89S51 microcontroller to design a vehicle alarm system. Its main function is to control the system through lock on engine start. Every time the driver must blow pipe. It will immediately start to unlock the system if the driver drinks not exceeding the standard. It will immediately sound the warning and continue to keep the engine start lock if the driver drinks exceeding the standard. Its efficiency and feasibility for adoption with simulation experiment is highlighted by Proteus.
