2008-09-26 09:23523776 graduation thesis. Doc: Ultrasonic ranging technology has been widely used in today's social life. On the basis of understanding the principle of ultrasonic ranging, the hardware and software design of ultrasonic ranging system based on the principle of time difference ranging is completed with SPCE06 1A series single chip microcomputer of Lingyang Company as the control chip. This paper mainly introduces the composition principle and application of ultrasonic ranging system composed of SPCE06 1A and ultrasonic ranging module, and introduces the application of LED display module. The system can be widely used in short-distance ranging, robot detection, vehicle reversing radar and home security system. Finally, the practical application shows that the basic measurement is feasible. Keywords ultrasonic ranging directory
