摘要
超声波测距系统具有使用方便,可靠性强等特点,被广泛用于建筑施工、倒车雷达、车距测量、管道测量等场合。文章首先介绍了采用AT89S52控制的超声波测距系统原理,考虑到温度对超声波测量的影响,着重阐述了DS18B20在测距时的测温原理及温度补偿方法。实验表明,采用温度补偿后的超声波测距系统明显提高了测量精度和稳定性。
Ultrasonic Ranging is characterized by easy operation and high reliability, so that it has being widely used to construction, measure the distance between cars, conduit measuring etc. This paper presents a method of using AT89S52 to control the ultrasonic, owing to the effect of temperature to the ultrasonic, so expounding the DS18 B20＇ s temperature measure and temperature compensation in Ultrasonic Ranging to improve the data＇ s precision and stability.
