介绍了一种基于单片机的汽车倒车测距仪的软硬件设计过程，系统以STC89C52为控制核心，采用温度补偿的超声波测距系统，实现倒车防撞报警功能。该倒车测距仪能测量并显示车辆后部障碍物与车的距离，同时用间歇的“嘟嘟”声发出报警，“嘟嘟”声的间隙随离障碍物距离的缩短而缩短。该系统的测距范围是0.1m-10m，具有结构简单、体积小、使用方便等特点。
介紹瞭一種基于單片機的汽車倒車測距儀的軟硬件設計過程，繫統以STC89C52為控製覈心，採用溫度補償的超聲波測距繫統，實現倒車防撞報警功能。該倒車測距儀能測量併顯示車輛後部障礙物與車的距離，同時用間歇的“嘟嘟”聲髮齣報警，“嘟嘟”聲的間隙隨離障礙物距離的縮短而縮短。該繫統的測距範圍是0.1m-10m，具有結構簡單、體積小、使用方便等特點。
개소료일충기우단편궤적기차도차측거의적연경건설계과정，계통이STC89C52위공제핵심，채용온도보상적초성파측거계통，실현도차방당보경공능。해도차측거의능측량병현시차량후부장애물여차적거리，동시용간헐적“도도”성발출보경，“도도”성적간극수리장애물거리적축단이축단。해계통적측거범위시0.1m-10m，구유결구간단、체적소、사용방편등특점。
Introduces a kind of hardware and software design process of automobile reverse distance measuring instrument based on MCU,the system uses STC89C52 as the control core,the ultrasonic ranging system with temperature compensation,realize the back-draft anti-collision alarm function.The telemeter for measuring and displaying the rear of the vehicle and the vehicle obstacle distance,at the same time with intermittent"beep"sound the alarm,"gap toot"sound decreases with the shortening of distance between obstacle.The range of the system is 0.1m-10m,which has the advantages of simple structure,small volume, convenient use etc.
