基于AT89C52的超声波测距系统设计

随着科学技术的不断发展,超声波测距装置得到了越来越多领域的应用.在超声波测距系统的运用场合中,其测距系统具有不同的精度,系统的误差较大,且常常不能满足应用的需求.论述了基于AT89C52单片机的超声波测距技术,可以实现无接触的测距功能,提出采用模块化设计,综合分析实现超声波测距仪的各种功能.

Ultrasonic Ranging System Based on AT89C52

With the continuous development of science and technology,ultrasonic distance measuring device has been used more and more fields. Ranging system have different precision in the same ultrasonic ranging system applicated occasions.the system error is large,and often can not meet the application requirements.This paper discusses the Ultrasonic Ranging Based on AT89C52 technology,can achieve non-contact distance measurement function,proposed modular design,a compre- hensive analysis of the various functions of the ultrasonic range finder.
