基于单片机的防醉驾系统设计

Design of Anti-drunk Driving System Based on Single Chip Microcomputer

酒后驾车是人们日常生活中面临的非常严峻的问题,为从根本上解决酒后驾车事件的发生,有必要设计一种具有自主防预酒后驾驶功能的智能装置,将酒后驾车扼杀在摇篮中,真正达到预防驾驶员酒后驾车的目的。该设计采用一款较为灵敏的MQ-3酒精浓度传感器,来检测测量人体内的酒精含量。如果显示器件上显示的酒精浓度值高于设定的酒精浓度标准值,蜂鸣器将会报警,发光二极管变亮,同时继电器做出相应动作,禁止汽车启动,以此达到预防驾驶员酒后驾车的目的。

Drunk driving is the really serious problem. In order to prevent drivers from drunk driving, a smart device is needed to design. This design applies a sensitive MQ-3 alcohol sensor to detect and measure the alcohol content in the human body. If the alcohol concentration displayed on the display device is higher than the set alcohol concentration standard, the buzzer will alarm, the LED will turn on, and the relay will act accordingly, banning the car from starting. The purpose to prevent drivers from driving after drinking is achieved.
