Abstract

The invention discloses a wire detection method and system, and the method comprises the steps: enabling a data collection device comprising a current detection apparatus and a position collection apparatus to move in a preset to-be-detected region, wherein the current detection apparatus collects current signals of different positions in the preset to-be-detected region in real time and transmits the current signals to a processing unit, and the position collection apparatus collects a position signal of the preset to-be-detected region and transmits the signal to the processing unit; converting the position signal into coordinates through the processing unit, carrying out data fusion of the coordinates and the current signals, and obtaining the coordinates and the current signals of positions corresponding to the coordinates; carrying out comprehensive processing of all coordinates and the current signal corresponding to the coordinates through the processing unit after the data collection apparatus collects the data of the preset to-be-detected region, obtaining a circuit distribution condition, and displaying the circuit distribution condition on a display apparatus. The system can carry out region detection in a non-damage manner, is low in cost, is portable, and can automatically complete the drawing of a circuit distribution map.

Description

technical field [0001] The invention relates to the technical field of electromagnetic detection, in particular to a wire detection method. The invention also relates to a wire detection system. Background technique [0002] In the current production and life, there are many conductive lines (such as circuits) buried in invisible places such as underground or inside walls, and workers often need to detect in order to determine the position of the wires. [0003] In the prior art, there are several detection methods for invisible wires as follows: [0004] Using the principle of electromagnetics for single-point detection, this method uses the characteristic of the induced magnetic field generated by the wire with alternating current around it to detect, which is more economical and convenient, but this method can only detect a certain point, but cannot For area detection, in addition, the detected position can only be recorded manually, and the drawing of the circuit distr...
