Abstract

The invention discloses a pipeline leakage monitoring method and a device thereof. The method comprises the following steps of acquiring pipeline stress waves and background noise, obtaining difference values of the pipeline stress waves and background noise at each corresponding time point, and determining a pipeline leakage state when the sum of the absolute values of each corresponding time point difference value is greater than a threshold value. The pipeline leakage monitoring device comprises an acquisition module, a data processing module and an identification module, wherein the acquisition module is used for collecting the pipeline stress waves and background noise; the data processing module is used for making a difference between the collected pipeline stress waves and the background noise, and calculating the sum of the absolute values of the difference values of each corresponding time point; and the identification module is used for determining the pipeline leakage state.By adopting the pipeline leakage monitoring method, the effects of reducing the noise and improving the signal-to-noise ratio and filtering are achieved, and real-time monitoring of pipeline leakagecan be realized.

Description

technical field [0001] The present application relates to the technical field of pipeline transmission, in particular to a pipeline leakage monitoring method and equipment thereof. Background technique [0002] The urban underground pipe network is not only an important public facility related to the economic lifeline of the people and national energy security, but also related to the safety of underground space. The technical means to maintain the integrity and safety of pipeline transmission are insufficient, and there are risks such as oil and gas pipeline fires and pipeline leakage polluting the environment. In addition, incidents such as communication optical cables being dug up and underground cables being stolen and cut frequently have brought serious impacts on people's normal production, life, and even national security. [0003] The leakage of the pipeline is due to the cracks or corrosion holes in the pipeline due to material corrosion and aging or other external...
