The present invention relates to a system for analyzing a location and an embedded depth of an underground pipe through analysis of an electromagnetic response, comprising: a low frequency transmitter; a three-element magnetic field measuring sensor; and a receiver. The three-element magnetic field measuring sensor deducts values of Hx (horizontal element), Hy, and Hz (vertical element) of each point measured in a direction perpendicular to a conductive pipe when current is artificially allowed to directly flow in the conductive pipe through the low frequency transmitter such that a magnetic field is generated due to electromagnetic induction. The receiver detects a position indicating the horizontal value maximum value and vertical element minimum value from value modeling data standardizing the change pattern depending on the measured point of each element (Hx, Hy, and Hz) deducted by the three-element magnetic field measuring sensor and obtains the position of the conductive pipe based on the detected position. According to an embodiment of the present invention, a measuring system investigating the location and embedded length of the conductive pipe by analyzing the electromagnetic response on a vertical upper part of the pipe and provided data for an analysis of underground facility management database (DB) through the measuring system are constructed. |
