摘要：为了降低汽车倒车时的碰撞事故,本文研究了基于单片机的超声测距倒车雷达.根据渡越时间测距原理,采用89C52单片机为主控制器,研制出了超声测距倒车雷达,并对测距误差进行了分析.雷达测距范围0.2～5.0米,最大测量误差不超过5%。
To decrease the numbers of collision accidents when automobile reversing, the ultrasound distance- measurement automobile- reversing radar based on microcontroller is studied. Based on the principle of time of flight distance measurement, microcontroller 89C52 is used as main controller to develop the ultrasound distance- measurement automobile- reversing radar, and the errors of dis- tance- measurement is analyzed too. The range of distance- measurement radar is 0.2～5.0m, the maximum error of distance- measure- ment is 5%.
