一种车载疲劳驾驶监测仪

摘要

针对目前私驾车的不断增加，对于安全驾驶的问题也越来越重视，除了自觉遵守交规以外，还要对日常驾驶过程中遇到的问题如疲劳驾驶进行监控和预警。以往只有高档车才有的功能如何用到中低挡车辆上，目前市面上有很多方案，在此介绍了一个低成本的设计方案，较好地实现车载疲劳驾驶监测。并介绍一种被动监测的方法来监测驾驶员的疲劳状态，通过采用一个低成本的手机模块组成的监测系统，实现对驾驶员眼睛状态的监控，以便确定驾驶员是否处于疲劳状态。同时通过声光报警提醒驾驶员，从而达到减少发生道路交通事故的目的。%　　In view of the current private car increases ceaselessly,the driving safety problems are paid more attention. in addition to consciously abiding by the traffic rules,the problems encountered in the process of daily driving,such as fatigue driving monitoring and early warning,should be considered. A low cost solution to put the functions that are available in only high⁃grade cars into the low price vehicles is proposed in this paper to realize the fatigue driving monitoring for all the drivers. A method of monitoring the drivers’eyes to determine whether the drivers are in a fatigue state or not with the help of low⁃cost mobile phone monitoring system is put forward in this paper. If a driver is in a fatigue state,the system will remind him with sound and light alarm so as to achieve the purpose of reducing road traffic accidents.
