An underground power cable path detection system based on electromagnetic method is proposed in this pa-per.This system aiming at the test site containing both running and non-running state of the cable, measures the three components of the magnetic field by three-axis high sensitivity magneto-resistive sensors above the ground, and uses pre-processing circuit to eliminate interference, then calculates the specific location of underground cables and the path toward by the magnetic field detection model, and completes the running and non-running cables′intelligent path detection.MATLAB and MULTISIM simulation respectively verify the feasibility of the magnetic field detection model and pre-circuit, which indicates that the system of underground power cable path intelligent detection has good practi-cality.
