Open publisher page 1 citations

Abstract

This paper introduces a distance measurement system via ultrasonic according to the realistic system,and the metrical range is between 0.1m～6.2m.The hardware component is designed based on microcomputer AT89C51.As this system is greatly effected by the temperature,we use the method of temperature compensation.In this way,when the distance is short,the relative error of the system is 2.5%～5%,when it is about 0.8m～6.2m,the relative error of the system can reach 0.2%～0.8%,which has satisfied the request of the system.It can offer a distance measurement method or an assistant visual system for industry field.
