The invention discloses a drunk-driving-preventing automobile safe driving system, which adopts a method of actively exhaling air by a driver to judge whether the driver drives after drinking or not,and is placed at the position of an automobile instrument panel; when the driver starts an automobile, the driver blows air to the system, and a sensor detects the alcohol to generate a voltage signaland amplifies the voltage signal; the 8-bit A/D converter converts the the voltage signal into a digital signal, the single-chip microcomputer processes and judges the digital signal, when the detected alcohol content does not exceed the standard, the relay is controlled to turn on the ignition device, the automobile can be started, and when the detected alcohol content exceeds the standard, thebuzzer gives an alarm, the detection indicating lamp is turned on, and the relay is controlled to cut off a power supply of the ignition device. The drunk-driving-preventing automobile safe driving system is designed for preventing drunk driving, is installed on an automobile, achieves automatic measurement, is high in intelligent degree and low in power, has a good effect on drunk driving prevention, and has good popularization value in practical application.

    本发明公开了防酒驾汽车安全驾驶系统,本系统采用驾驶员主动呼气的方法,判断驾驶员是否是酒后开车,该系统放置在汽车仪表盘位置,当司机发动汽车时,驾驶员向本系统吹气,传感器检测酒精后产生电压信号放大后,通过8位A/D转换器转换为数字信号,单片机对数字信号进行处理判断,当检测到的酒精含量没有超标时,控制继电器打开点火装置,汽车可以启动,当检测到的酒精含量超标时,蜂鸣器报警,同时检测指示灯亮,控制继电器切断点火装置的电源,车辆熄火,本防酒驾汽车安全驾驶系统为预防酒后驾驶而设计,安装在汽车上,自动测量、智能化程度高、功率低,对预防酒后驾车具有很好的效果,在实际应用中具有很好的推广价值。
