Description

Technical Field

[0001] The present invention relates to the technical field of pipeline leakage monitoring, and in particular to a pipeline leakage monitoring device, system and method. Background Art

[0002] Gas is a high-risk gas, and gas pipeline leakage can easily cause gas accidents and endanger personal safety. Existing gas pipeline leakage detection is completed by laying a large number of sensors around the pipeline or by technicians holding sensor detection devices to detect along the pipeline. When a large number of sensors are laid around the pipeline, each sensor covers a large range, and can only determine an approximate pipeline leakage section. Further detection is required to determine the exact leakage point. The detection cycle is long, and a lot of material resources and time are consumed, and the detection accuracy is low. Although the detection method of using a handheld sensor detection device to detect along the pipeline can accurately determine the leakage location, it requires the technician to hold the sensor detection device to the leakage point before it can be detected. The detection result is not timely, and the technician needs to be close to the gas leakage point, which poses a threat to the personal safety of the technician. Therefore, there is an urgent need for an efficient and accurate pipeline leakage monitoring device, system and method. Summary of the invention
