During the fixed-point detection of power safety construction, the on-site environment is complex and diverse, and there is a problem that the relationship between the sensor output data and the final position label is not fitted, resulting in a large positioning error. A power safety construction method based on an electromagnetic induction sensor is proposed. The position layout of electromagnetic induction sensors is preset so that two mutually perpendicular sensors are distributed along multiple scanning lines in the direction of the pipeline. Wavelet transform is used to denoise the collected electromagnetic induction sensor signal, and a relatively pure electromagnetic signal is obtained. By selecting the location of training point and scanning line, establishing the positioning model of underground cable channel by using noise reduction signal, and speculating the location information of possible scanning line and underground pipeline intersection, the cable pipeline can be tracked and detected. When the line is electrified, the surveyors can keep enough safe distance from the electrified body to ensure the safe construction of power. After testing, this method can judge the power cable path and improve the positioning accuracy of the cable pipeline. The average positioning error is 1.25m, which is 2.28m and 3.03m less than the safe construction method based on GPS and GPR.
