摘要
超声波测距是一种有效的非接触式测距方法,能够克服传统测距方法的不足。利用AT89C51定时功能来计算超声波在媒质中的传播时间,进而计算出超声波在媒质中的传播距离。该仪器在工业控制、能源勘探、水利监测等领域具有广泛的应用。
The ultrasonic range finding is an efficient non -contact method for range finding, which can remedy the deficiency of any conventional range finding methods. The time that the ultrasonic travel in a medium is reckoned by means of the AT89C51 timing function. Consequently,the distance that the ultrasonic travel in a medium can be worked out. This instrument is widely used in industrial control, energy exploration, irrigation works and so on.
