摘要
酒后驾车的危害十分巨大,因此,笔者介绍了一种基于单片机的防酒驾控制系统。系统由酒精传感器MQ-3测量汽车驾驶员体内的酒精含量浓度,通过A/D转换器转换成数字信号传给单片机,经过单片机处理后显示酒精浓度,当浓度大于规定数值时,语音播报模块发出警报,并通过继电器切断汽车内的油箱电源或关闭阀门。系统能够有效防止酒驾,起到了安全出行的效果。
The harm of drunk driving is very huge. Therefore, the author introduces a kind of control system based on single chip microcomputer. The system measured the alcohol concentration in the driver＇s body by the alcohol sensor MQ-3, converted it into a digital signal through the A/D converter to the single-chip computer, and showed the alcohol concentration after the single-chip microcomputer processing. When the concentration was greater than the specified value, the speech broadcast module issued an alarm. And through the relay to cut off the fuel tank power in the car or close the valve. The system can effectively prevent drunk driving, which has the effect of safe travel.
