Pipeline leakage detection method

Abstract

The invention relates to a pipeline leakage detection method, and belongs to the technical field of intelligent sensing mechatronics. The method specifically comprises the steps that S1, audio data in a pipeline are collected in an ultrasonic sensing mode, and key information is obtained; s2, MELGAN is used to expand the collected small sample practical audio data so as to enhance the generalization ability of the trained model; s3, the small sample audio data and the sample enhanced data are combined and sent to a yov3 model for training so as to obtain a pipeline leakage detection identification model with improved identification accuracy. When the pipeline leaks, the leakage position in the pipeline can be accurately judged in time, the leakage phenomenon of the pipeline can be efficiently and accurately found, the pipeline can be timely processed, and targeted guidance can be obtained; and the method can effectively solve the problem that the recognition accuracy is not high when a small sample training model is used.

Description

technical field [0001] The invention belongs to the technical field of intelligent sensor electromechanical integration, and relates to a pipeline leakage detection method. Background technique [0002] In the production process of gas pipelines, there are inevitably some small defects. For example, natural factors, man-made damage, and cracking of the insulation layer of the gas pipeline. These defects will slowly corrode the gas pipeline, and eventually lead to accidents such as damage and leakage of the gas pipeline, causing serious economic losses, thus affecting people's lives and safety. Property security poses a threat [1]. And in the case of long-distance gas pipeline transportation, the gas pipeline can be installed in the wild or in residential areas. Once the gas pipeline ruptures and leaks, it will not only affect normal production, but also cause direct economic losses, and even cause serious damage in some cases. Consequences, such as fires and environmental ...
