摘要：
In the design of ultrasonic ranging system, MCS51 singleship is used as the core component of the hardware system and the control software is used. The software is designed with advanced microcontroller programming language. Closed loop control is used to adjust the amplitude of received signal and to extract the ultrasonic propagation time. The double closed loop control technique of amplitude and time improves the measuring accuracy of the instrument. In the experiment, the principle of transmitting and receiving ultrasonic ranging, the transmitting circuit and the receiving circuit are introduced in detail, and the experimental results are analyzed in detail too[4][6] . The experimental results show that the measurement accuracy of the system is greatly improved.
