摘　　要：随着现代工业技术的进步,古代沿袭的接触式测距方式在某些特殊情景存在难以接触目标的缺陷,例如,在进行深油井深度测距时工作人员难以直接接触井底。该文针对接触式测距的局限性,利用超声波高精度、无损、非接触等优势,设计了一种基于单片机AT89S52的超声波测距仪。With the advancement of modern industrial technology,the contact ranging method that was handed down in ancient times has the defect of being diff icult to reach the target in some special work scenes.For example,when measuring the depth of deep oil wells,it’s hard for workers to directly reach the bottom of the well.In view of the limitations of contact ranging,this paper designs an ultrasonic range-f inder based on single chip microcomputer AT89S52 by taking advantages of the high-precision and non-contact of lossless ultrasonic.
