摘要
酒后驾驶已严重威胁到人们的出行安全。针对这一问题,设计了一种能够有效防止酒后驾驶的自动控制系统。该系统由酒精传感器MQ-3、AD转换器TLC548、STC89C52单片机、报警电路、LCD显示、继电器等构成。当酒精传感器探测出司机呼出气体酒精浓度超标时,该系统能自动切断汽车启动系统电源,从而实现限制酒后驾驶的功能。
Drink driving is a serious threat to the safety of people＇s travel.To solve this problem,designed automaticcontrolsystem that can effectively prevent drink driving.The system consists of the MQ-3 Alcohol Sensor,AD converter TLC548,STC89C52 MCU,the alarm circuit,LCD display,relay and other composition.When the alcohol sensor to detect the driver exhaled breath alcohol concentration in excess of,the system can automatically cut off the car to start the system power,and thus limit for drink-driving.
