Experimental study on the design from the perspective of analysis, an analysis of vehicle collision avoidance system to reverse the basic design principles as well as anti-collision system at home and abroad such problems. A more detailed ultrasonic ranging system, as well as under the system design, developed by auto reverse anti-collision alarm, it can automatically detect the distance between the rear obstacles. When the time limit, it can issue a sound and light alarm to alert the driver brakes. In addition, it can reverse the course of a "reverse, please note that" the alarm to warn pedestrians. Domestic manufacturers design universal components, low cost, reliable performance and is conducive to the promotion. Ultrasonic distance sensor using piezoelectric element of lead zirconium titanium, commonly known as RZT, the characteristics of this sensor is to have a direction, the reversing motor vehicle sonar system with the use of ultrasonic distance sensors, "echo" phenomenon made, reversing to launch vehicle rear ultrasound, ultrasound determination of obstacles encountered by the time after the return, he will receive the vehicle to obstacle distance.

This article elaborated the ultrasonic ranging basic principle, thesurvey, the computational method, and detailed introduction based onultrasonic ranging technology application back-draft radar systemdesign. This system the microprocessor technology and the ultrasonicwave range finder technology, the sensor technology and so on unifies,may examine the automobile in the back-draft process, after thevehicle the obstacle and the automobile distance, through the liquidcrystal display monitor demonstration obstacle distance, the position,and is away from the police according to the obstacle and thetailstock which far and near real-time sends out the different rank toshow the sound.
