The invention relates to the technical field of fatigue detection equipment, and discloses an urban rail driver fatigue detection method. The method comprises the steps that an urban rail is operated, and each module on a detection platform is started; an acquisition module acquires face information of a driver, converts the face information into an electric signal and sends the electric signal to the controller, and the controller generates a face image according to the electric signal and extracts face feature points; the controller calculates the eye closing time of the driver according to the human eye feature points in the human face feature points, and a timer calculates the time when the driver is in the eye closing state; if the time of the eye closing state is longer than 5s, the driver is in a fatigue state; if the time of the eye closing state is less than 5s, the driver is in a waking state; when the driver is in the fatigue state, a reminding module reminds the driver, meanwhile, the controller calculates the eye closing time of the driver again, and the reminding module stops working until the driver is in the waking state. The method has the advantages that the driver can be reminded to adjust the state in time, and the safety coefficient of urban rail driving is high.
本发明涉及疲劳检测设备技术领域,公开了一种城轨司机疲劳检测方法,包括步骤如下:城轨运行,检测平台上的各个模块开启;采集模块采集司机的人脸信息,并转化为电信号发送至控制器中,控制器根据电信号生成人脸图像并提取人脸特征点;控制器根据人脸特征点中的人眼特征点计算司机的闭眼时间,计时器计算处于闭眼状态的时间;若处于闭眼状态的时间大于5s,司机处于疲劳状态;若处于闭眼状态的时间小于5s,司机处于清醒状态;当司机处于疲劳状态时,提醒模块对司机进行提醒,同时,控制器再次计算司机的闭眼时间,直至司机处于清醒状态时,提醒模块停止工作。本发明具有能及时提醒司机调节自身状态,城轨行驶的安全系数高的优点。
