摘要
针对汽车倒车碰撞事故,设计了以单片机为核心的倒车雷达预警系统,它利用超声波实现无接触测距;利用温度传感器实现温度补偿,使测距精确;利用液晶显示实现距离可视;同时具备语音报警的功能。实验表明,该系统测距范围、测距精度可以满足系统要求,具有较高的应用价值。
In order to avoid collision accident in automobile-reversing,the automobile-reversing radar alarming system based on Single-Chip computer has been designed.In this system,ultrasonic is used to realize range acquisition without contact;temperature sensor is used to realize temperature compensation in order to improve measure precision;liquid crystal display（LCD） is used to realize distance visible,and the system has pronunciation warning function.The experiment indicates range acquisition scope and precision can satisfy the system＇s request,and the system has good application value.
