摘　　要：文章针对车辆正常运行和车辆防盗问题,提出了汽车无线防盗防撞报警器的设计方案。该系统主要对车辆行驶(包含前进、倒车、转弯)的环境进行判别,用两车之间的间隔或者车与障碍物的距离作为判断依据,一旦达到危险极限阀值,系统会发出危险警报提醒,大幅度减少交通事故的发生。此报警器以单片机为主体结构,包含了4个不同的模块:数据显示、距离测量、无线发射和无线接收。采用单片机(STC89C51)为主控器,用超声波进行测距,震动检测模块检测震动,并使用发光二极管进行数据的显示。此系统具备显示效果直观、电路简单易懂、切换简单方便、成本低廉等优点,市场前景非常广阔。Aiming at the problems of vehicle normal operation and vehicle anti-theft,this paper puts forward the design scheme of wireless anti-theft and anti-collision alarm for automobile.The system mainly discriminates the environment of the vehicle driving including forward,reverse,turn,using the interval between the two vehicles or the distance between the vehicle and the obstacle as the basis for judgment.Once the danger limit threshold is reached,the system will issue a danger alarm warning and greatly reduce the occurrence of traffic accidents.This alarm takes the single chip microcomputer as the main structure and contains 4 different modules:data display,distance measurement,wireless transmission and wireless reception.Single chip microcomputer(STC89C51)is used as the main controller,ultrasonic is used for ranging,vibration detection module is used to detect vibration,and LED is used for data display.This system has the advantages of visual display effect,simple and easy to understand circuit,simple and convenient switching,low cost and so on.
