摘要
介绍了根据电磁感应原理测量钢（套）管接箍位置的方法，讨论了感应电压的信号特征及信号处理、采样、信号识别等问题，最后介绍了用曲线跟踪原理确定深度，减小深度误差的方法。
The method of measuring the location of the steel tube'sjoining hoops is introduced,using the electromagnetic inductionprinciples.It then discusses such problems as the signal features,signal sampling, signal treatment and aignal identification of the in-duction voltage. The method of using the curve tracing principles tomeasare depth and to minimize depth errors is introduced.
