The invention discloses a simple drunk driving prevention system which comprises four alcohol concentration acquisition terminals and a drunk driving prevention control terminal. Each alcohol concentration acquisition terminal consists of a ZigBee wireless communication module, a power supply module and an alcohol concentration acquisition sensor; a CC2530 chip with the working voltage of 2V-3.6 V, low power consumption and high wireless communication capability serves as the ZigBee wireless communication module to receive signals of an alcohol concentration acquisition sensor and communicatewith the drunk driving prevention control terminal in the system; an MQ _ 3 alcohol detection sensor pool is adopted as the alcohol concentration acquisition sensor. Digital filtering processing is carried out on data collected by the four alcohol concentration acquisition sensors installed on the top of an automobile steering wheel and the top of a cab seat, so that the accuracy of an alcohol concentration detection value can be improved, system misoperation caused by an inaccurate alcohol concentration detection value is avoided; and the data of the alcohol concentration acquisition sensor is transmitted by adopting a ZigBee wireless network, and the installation and wiring process of the system can be greatly simplified.

    本发明公开一种简易防酒驾系统,包括四个酒精浓度采集终端和防酒驾控制终端,所述酒精浓度采集终端由ZigBee无线通信模块、供电模块和酒精浓度采集传感器构成;所述ZigBee无线通信模块采用工作电压为2V‑3.6V的低功耗、无线通信能力强的CC2530芯片,在系统中起到接收酒精浓度采集传感器信号及与防酒驾控制终端通信的作用,所述酒精浓度采集传感器采用MQ_3酒精检测传感器池。通过对安装于汽车方向盘和驾驶室座椅顶部的四个酒精浓度采集传感器采集回来数据的数字滤波处理,可提高酒精浓度检测值的准确性,避免由于酒精浓度检测值不准确所引起的系统误操作,将酒精浓度采集传感器的数据采用ZigBee无线网络进行传输,可极大简化系统安装布线的过程。
