摘　　要：设计实现了一种检测驾驶员疲劳状态的安全警报系统,包括位于驾驶员前面的摄像头和驾驶员戴在颈部的颈枕。摄像头对驾驶员眼部状态进行检测,判断驾驶员的疲劳程度,颈枕内的压力传感器对驾驶员颈部位置进行检测,进一步提高驾驶员疲劳程度判断的准确性。当驾驶员处于疲劳状态时,启动颈枕内的振动传感器发出振动报警信号,并循环检测驾驶员的疲劳状态。当多次报警提醒无效时,系统判断驾驶员处于严重危险状态,向指定设备发送定位求救信号,进行远程呼救,提高汽车驾驶的安全性。A safety alarm system is designed and implemented for detecting driver fatigue state,which includes the camera in front of the driver and the neck pillow worn by the driver.The camera detects the driver’s eye state to judge the driver’s fatigue degree,and the pressure sensor in the neck pillow detects the driver’s neck position,so as to further improve the accuracy of judging the driver’s fatigue degree.When the driver is in the state of fatigue,the vibration sensor in the neck pillow will be started to send the vibration alarm signal,and the fatigue state of the driver will be detected cyclically.When multiple alarm reminders fail,the system judges that the driver is in serious danger,and sends positioning distress information to the designated equipment,and calls for help remotely,so as to improve safety of vehicle driving.
