Study on Ultrasonic Ranging System Design

摘要：

Ultrasonic Ranging System is different precision when it has been used in an occasion. Generally its errors are larger and often can not meet the application requirements. In this paper, new ultrasonic ranging system which can be used to non-contact measure distance in special occasion was designed by single-chip, ultrasonic ranging technology and sensor technology. Distance measurement data and temperature were displayed through LCD screen and the transmitting and receiving of ultrasonic were controlled by single-chip microcomputer according to the time difference location method to measure the distance. in order to improve measurement accuracy, temperature sensor has used to measure temperature and compensate temperature, the system also uses a voice broadcast system, which makes it higher accuracy,more convenient and extensive applications.
