摘　　要：为了有效地防止驾驶员酒后驾车的行为,设计了一种基于单片机车载酒精浓度的检测系统。该系统由酒精传感器、A/D转换器、AT89S52单片机控制器、语音报警、LCD液晶显示、LED指示灯、车门锁传感器、压力传感器和继电器等构成。当酒精传感器检测出司机体内的酒精浓度超标时,该系统能够自动的切断汽车起动机,使发动机不能起动,从而实现其控制功能。Alcohol detection system on the automobile based on MCU is designed in order to prevent the driver drunk driving this behavior. The system is consisted of alcohol sensor,the A/D converter,the AT89S52 MCU controller,speech warning system,LCD liquid crystal display,LED lights,car door sensors,pressure sensors and relay,etc. The system can automatically cut off the motor starter,and the engine can＇t start so as to realize its control function when alcohol sensors detect the driver exhaled breath excess alcohol concentration.
