Traffic congestion has bee more and more serious, the crash occurred repeatedly, resulting from the inevitable casualty and economic loss, 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 mon type of distance measuring method, this paper describes the use of ultrasonic locating design a backdraft anticollision alarm system.The content of the thesis is based on the AT89C51 singlechip integration, design based on AT89C51 backdraft anticollision alarm system. The system uses a bination of hardware and software, the method of module, and multiuse characteristics. This paper summarizes the development and basic principle of ultrasonic detection, introduces the principle and characteristics of ultrasonic sensor. Some of the main parameters for the system were discussed, and introducing ultrasonic ranging system functions basis, the overall position of the system, through a variety of transmitting and receiving circuit design parison, the best design scheme, and various system design unit this paper introduces the principle of. On the position of the system circuit chip are introduced, and elaborated the principles of their work. This paper introduces the software structure of system, programmed to realize the function of the system. Finally, throug
