货车防疲劳驾驶系统设计

Design of Anti Fatigue Driving System for Trucks

文章从货车驾驶员在行车过程中驾驶状态的检测、疲劳的判断和防疲劳装置的设计三个方面进行阐述。首先通过对货车驾驶员的状态信息进行收集,而后传送到系统主机判断驾驶员是否疲劳,当判断超过阈值就可以把信号传递给执行机构,发光二极管(LED)灯闪烁,蜂鸣器、座椅振动等执行装置同时给予驾驶员疲劳驾驶提示,从而将驾驶员唤醒。为某货车防疲劳驾驶提供一种切实可行的方案,减少疲劳驾驶的现象,降低交通事故率,保障交通出行的安全。

This paper elaborates from three aspects,the detection of driving state,the judgment of fatigue and the design of anti-fatigue device.First,the truck driver's state information is collected,and then transmitted to the system host to judge whether the driver is tired.When the judgment exceeds the threshold,the signal can be transmitted to the actuator,and the actuator such as light-emitting diode(LED)light flashing,buzzer and seat vibration will give the driver a warning of fatigue driving at the same time,so as to wake the driver up.This paper provides a practical scheme for a truck to prevent fatigue driving,reduce the phenomenon of fatigue driving,reduce the traffic accident rate,and ensure the safety of traffic travel.
