[0002] Gas pipelines are important infrastructure used for public utilities or civil purposes within cities or towns; specifically, gas pipelines refer to public gas pipelines and their ancillary facilities from gas plants and stations such as gate stations, storage and distribution stations, and various gas source plants and stations to users or between plants and stations.

[0003] Gas is flammable and explosive. Once a pipeline leaks, it can easily cause serious safety accidents such as fire or explosion, posing a threat to the safety of people's lives and property. Therefore, it is necessary to conduct leak detection regularly or irregularly to detect and deal with leaks in a timely manner to ensure the safe operation of the pipeline.
