Due to the increasing number of private cars in today's society, there are a lot of safety problems in car reversing. This paper proposes a research program of ultrasonic ranging car reversing radar system with higher accuracy and better warning effect. According to the principle of ultrasonic ranging, the AT89C51 single-chip microcomputer is selected as the core circuit, and the anti-interference error processing is adopted in the processing of the single-chip microcomputer to solve the multiple measurement, the transmission time interval and the dead zone measurement problem of the ultrasonic ranging. Car reversing radar system based on ultrasonic ranging adopt transmitting and receiving circuit, will determine the time difference in the single chip microcomputer. the results are sent to the digital display circuit and voice broadcast circuit. Finally, it is verified by experiments that after ultrasonic error measurement adopts error processing, under the complicated environmental conditions, the accuracy of ranging is higher, the number of false alarms is reduced, and the device has high reliability and practicability.
