摘　　要：简要介绍了地下管线探测仪的基本工作原理,建立了一个简化载流地下金属管线的电磁场分布模型,提出了一种基于电磁法原理的多线圈的管线探测仪接收机的设计方案,并且运用电磁场理论,从功能上对接收机天线(即线圈)的工作过程,包括目标管线的路由走向的标定,直读深度估算以及管线上感应电流的大小的确定等进行了定量的分析。并且给出了简要的信号处理流程,最后对可能的误差问题和改进措施作了简要的探讨。Operational fundamental of underground pipeline is briefly introduced and a simplified model of the electromagnetic field distribution of underground pipeline loaded with alternating current. Then, a scheme of four-antenna （loop） receiver is proposed based on the electromagnetic detection method. Combined the theory of electromagnetics, the operational functions of the receiver＇s antennae,including the direction tracing of target buried pipeline, depth calculation and the determination of the strength of induced current loaded on the pipeline, are analyzed with quantificational illumination. At last, the potential error problems are discussed following several improving advices.
