摘　　要：我国汽车保有量逐年增长,汽车安全事故发生频率也越来越高,针对汽车的安全问题设计了一种汽车安全预警装置。该装置基于Arduino,在汽车行驶过程中通过防碰撞模块,用超声波传感器实时测量与前车的车距,一旦与前车的距离小于设定的阈值时触发蜂鸣器预警模块;通过防追尾模块,用超声波传感器实时测量与后车的车距,小于设定的阈值时触发车尾红色LED灯光向后车驾驶员示警;酒驾也是导致汽车安全事故的主要原因之一,该装置中还含有防酒驾模块,通过酒精传感器测量车内的酒精含量,超过设定的酒精含量阈值将触发语音提示模块提醒驾驶员,进一步提高汽车的行驶安全。China’s car ownership is increasing year by year,and the frequency of automobile safety accidents is getting higher and higher,and designed a car safety early warning device for automobile safety problems.The device is based on Arduino,which measures the distance from the vehicle in front in real time with an ultrasonic sensor through the collision avoidance module during the driving of the car,and triggers the buzzer warning module once the distance from the vehicle in front is less than the set threshold.Through the anti-rear-end module,the distance between the vehicle and the rear vehicle is measured in real time with an ultrasonic sensor,and when it is less than the set threshold,the red LED light at the rear of the vehicle is triggered to warn the driver of the rear vehicle.Drunk driving is also one of the main causes of car safety accidents,this device also contains an anti-drunk driving module,through the alcohol sensor to measure the alcohol content in the car,exceeding the set alcohol content threshold will trigger the voice prompt module to remind the driver,further improve the driving safety of the car.
