The application discloses a pipeline leakage monitoring method and its equipment. The method includes the following steps: collecting the pipeline stress wave and background noise, obtaining the difference between the pipeline stress wave and the background noise at each corresponding time point, and the difference value of each corresponding time point When the sum of the absolute values is greater than the threshold, the pipeline leakage state is determined; the pipeline leakage monitoring equipment includes an acquisition module, a data processing module, and an identification module, and the acquisition module is used to acquire pipeline stress waves and background noise; the data processing module , used to make a difference between the collected pipeline stress wave and background noise, and calculate the sum of the absolute values of the differences at each corresponding time point; the identification module is used to determine the pipeline leakage state. By adopting this pipeline leakage monitoring method, noise reduction, signal-to-noise ratio improvement and filtering effect can be realized, and real-time monitoring of pipeline leakage can 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...
