The virtual experiment platform can provide instructional means for real experiments, and can provide a basic tool for developing the acquisition instrument and recognizing defect signals.

Description

technical field [0001] The invention relates to the monitoring field of buried ferromagnetic metal pipelines, in particular to a virtual experiment platform for magnetic tomography detection of buried ferromagnetic metal pipelines and a use method thereof. Background technique [0002] Pipeline transportation, as a major mode of transportation for strategic resources such as oil and natural gas, its safe and reliable operation is crucial to safeguarding people’s lives and property, energy supply and the ecological environment. Discovering and identifying unsafe factors in pipelines is crucial to protecting oil and gas The safe operation of pipelines is of great significance. [0003] The stress concentration or damage of buried ferromagnetic metal pipelines caused by machining, collision, welding, load, temperature, corrosion and other factors will cause abnormal magnetic field due to the magnetic memory effect in the geomagnetic environment. The sensor array is used to mea...

Problems solved by technology

[0008] 4) Multiple defect types: cracks, holes, metal loss, external force, deformation, etc.;

[0009] 5) A variety of defect parameters: taking metal loss as an example, metal loss shape, metal loss depth, internal and external corrosion;

[0010] 6) Defects in different positions: the position on the pipeline axis and the position in the direction of the hour (0-360 degrees);

[0011] 7) Combination of multiple defects;

[0014] Every time a new type of acquisition instrument is developed, it is necessary to complete the experiments of the above working conditions, and the more physical experiments, the longer the cycle, the higher the cost, the more interference factors, and the higher the risk factor will be. Considering some defects, it is difficult to meet the predetermined requirements ( Such as the strength of the defect, the hourly position of the pipeline where the defect is located, etc.), it is often impossible to complete the experiment
