Problems solved by technology
[0002] Gas pipelines cause gas leakage due to factors such as pipeline occupation, deterioration, aging, natural disasters, and man-made damage. When the gas leakage makes the gas concentration outside the gas pipeline reach a certain value, once it encounters a fire source, it can cause an explosion, thus giving Residents near gas pipelines pose safety hazard
[0003] The current gas pipeline leakage traceability method is inaccurate in locating the leakage source

Embodiment Construction
[0035] The technical solutions in the present invention will be clearly and completely described below with reference to the embodiments and the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] A method for tracing the source of gas pipeline leakage, such as figure 1 shown, including the following steps:
[0037] S1, if the gas monitoring device detects the leakage of the gas pipeline, the target pipe section where the leakage source is located on the gas pipeline is obtained from the farthest diffusion distance of the gas and the position of the gas monitoring device. The farthest diffusion distance in the medium between the pipeline and the gas monitoring device. In this embodiment, the farthest diffusion distance is the diffusion distance required for the concentration of the gas lea...

The invention relates to the technical field of gas safety monitoring, in particular to a method for tracing the source of gas pipeline leakage. If the gas monitoring device detects the leakage of the gas pipeline, the target pipe section where the leakage source is located on the gas pipeline is obtained from the farthest diffusion distance of the gas and the position of the gas monitoring device; Diffusion distance, obtain the gas diffusion area where the target pipe section is located; obtain the gas leakage source on the target pipe section from the gas concentration and the farthest diffusion distance of the gas in the medium in the diffusion area. The leak source tracing method of the present invention firstly determines the target pipe section where the leak source is located, and then further shortens the length of the target pipe section until the specific location of the leak source is determined. Therefore, the leak source tracing method of the present invention can locate the leak source on a very short target pipe section, thereby improving the location accuracy of the leak source position, so as to facilitate the maintenance department to repair the leaked gas pipeline in time.
Description
technical field [0001] The invention relates to the technical field of gas safety monitoring, in particular to a method for tracing the source of gas pipeline leakage. Background technique [0002] Gas pipelines cause gas leakage due to factors such as pipeline occupation, deterioration, aging, natural disasters and man-made damage. When the gas leakage makes the gas concentration outside the gas pipeline reach a certain value, once it encounters a fire source, it can cause an explosion, thereby giving Residents near gas pipelines pose a safety hazard. [0003] The current gas pipeline leakage traceability method is inaccurate in locating the leakage source. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems, the present invention provides a method for tracing the source of gas pipeline leakage, which can improve the positioning accuracy of the leakage source on the gas pipeline. [0005] To achieve the above object, the present invention ha...
