Embodiment 1
[0081] The invention provides a method for eliminating interference of parallel pipelines in the detection of AC and DC stray currents of buried pipelines.
[0082] S1. Select the position where there are parallel buried pipelines to be detected;
[0083] S2. Each pipeline corresponds to three magnetometer probes, and the three magnetometer probes are arranged in a horizontal array at equal intervals on the surface where the corresponding buried pipeline is located;
[0084] Two parallel pipes, pipe one corresponds to probe one, probe two, probe three; pipe two corresponds to probe four, probe five, probe six;
[0085] S3. When there are AC and DC stray currents in the pipeline, the six probes respectively detect the magnetic fields at their respective positions;
[0086] S4, according to the result of S3 detection, obtain the vertical component size of external stable magnetic field interference, eliminate the vertical component influence of external stable magnetic field in...
Embodiment 2
[0093] see figure 1 , when placing the probe array, make the pipeline 1 be located directly below the middle of the horizontal connection line between probe 2 and probe 3, and the projection of the horizontal connection line between probe 2 and probe 3 on the horizontal plane and the projection of the central axis of pipeline 1 on the horizontal plane are perpendicular to each other; Probe 1 is located on the extension line of the horizontal connection between probe 2 and probe 3, and probe 1 is located on the side away from pipe 2;
[0094] The pipeline 2 is located directly below the middle of the horizontal connection line between the probe 4 and the probe 5, and the projection of the horizontal connection line between the probe 4 and the probe 5 on the horizontal plane and the projection of the central axis of the pipeline 2 on the horizontal plane are perpendicular to each other; the probe 6 is located between the probe 4 and the probe 5. The probe 5 is on the extension l...
