The invention relates to the technical field of automobile safe driving, in particular to a vehicle-mounted anti-fatigue driving system which comprises a reflective infrared sensor, a grip strength fluctuation acquisition module, a lane departure early warning module and a facial feature recognition module. The reflective infrared sensor comprises an infrared emitting diode and two infrared receiving heads. The grip strength fluctuation acquisition module comprises a pressure sensor, an analog-digital converter, an AD7705 conversion circuit and a single-chip microcomputer. The lane departure early warning module comprises a laser ranging radar and a voice prompt chip. The facial feature recognition module comprises a DSP digital signal processing chip and a camera. The beneficial effects of the system are that the system achieves omnibearing monitoring of the fatigue driving state of the driver through the collection of the distance of the head of the driver deviating from the headrestof the seat, the grip fluctuation of the driver for the steering wheel, the departure state of the lane from a lane line and the facial features of the driver, and compared with early warning equipment in the prior art, the detection quality and efficiency are improved.
本发明涉及汽车安全驾驶技术领域,具体涉及一种车载防疲劳驾驶系统包括反射式红外线传感器、握力波动采集模块、车道偏离预警模块、面部特征识别模块,反射式红外线传感器包括一个红外线发射二极管和两个红外线接收头,握力波动采集模块包括压力传感器、模数转换器、AD7705转换电路、单片机,车道偏离预警模块包括激光测距雷达、语音提示芯片;面部特征识别模块包括DSP数字信号处理芯片、摄像头。本发明的有益效果:通过采集司机头部偏离座椅头枕位置的距离、司机对方向盘的握力波动、车道偏离车道线的状态以及司机的面部特征,从而全方位地对司机的疲劳驾驶状态进行监测,相对现有技术中的预警设备,提高了检测的质量及效率。
