Abstract ：With the development of society and economy of transportation industry is booming, the automobile quantity climbs in the first mate. Traffic congestion has become more and more serious, the crash occurred repeatedly, in view of this situation, design a kind of fast response, high reliability and more economy car collision avoidance warning system to be imperative, ultrasonic ranging method is the most common type of distance measuring method, this paper describes the use of ultrasonic distance measurement method is to design a back-draft anti-collision alarm system. The content of the thesis is based on the AT89C51 single-chip microcomputer reverse anti-collision system design, mainly using the ultrasonic features and advantages, ultrasonic ranging system and AT89C51 single chip integration. This paper summarizes the development and basic principle of ultrasonic detection, introduces the principle and characteristics of ultrasonic sensor. This paper introduces the software structure of system, programmed to realize the function of the system. Finally, through the analysis of system error, giving the system improvement program.
