摘要
利用超声波测量淤泥界面是一种精度较高,费用低廉的测量技术。本 文阐述了利用包络线法测量污泥厚度的原理,介绍了实现该原理的系统构成 和硬、软件的设计方案,并提出了适合单片机的数据处理算法。
The measurement of mud-water interface by using ultrasonic is a measuring technique with high precision and low cost. Here presents principle of measuring the height of mud by using the envelope of received signal. It included the systematic structure as well as the design of its hardware and software. An algorithm of data processing suitable for 80C196 single-chip microcomputer data is also proposed.
