The invention provides an intelligent drunk driving prevention system. The system comprises a fuel type expiration type alcohol sensor arranged in front of a driver seat and used for detecting the alcohol content in air exhaled by a driver, an image acquisition device which is arranged in front of the driver seat and used for acquiring a face image of the driver in the driving process, a temperature acquisition device which is arranged in front and used for measuring the body temperature of the driver in the driving process, and a control system which is used for judging whether drunk drivingexists or not according to the alcohol content, the face image and the body temperature, and controlling the vehicle to stop driving when drunk driving exists. While the drunk driving detection accuracy is improved, the operation and data transmission amount of face image detection is reduced, and thus drunk driving detection is faster. Response speed is faster. When drunk driving is detected, driving can be actively controlled, and the traffic safety can be further improved.
本发明提供了一种智能防酒驾系统,包括:设置于驾驶座前方的燃料型呼气式酒精传感器,用于检测驾驶员呼出气体中的酒精含量;设置于驾驶座前方的图像采集装置,用于获取驾驶员在驾驶过程中的面部图像;设置于前方的温度采集装置,用于测量驾驶员在驾驶过程的体温;和控制系统,所述控制系统用于根据所述酒精含量、面部图像和体温判断是否为酒驾,在为酒驾时,控制车辆停止行驶。在提升酒驾检测准确率的同时,减少面部图像检测的运算和数据传输量,进而使得酒驾检测更加快速。响应速度更快。在检测到酒驾时,可以主动对行车进行控制,可以进一步提升交通安全。
