Abstract: 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.
