Method and system for locating pipeline leakage

Abstract

The invention relates to a method and system for locating pipeline leakage. The method includes setting two detection equipment for collecting pipeline signals on the pipeline at a certain distance; synchronizing the internal time of the two detection equipment to the Beidou satellite reference time ; Match the suspected water leakage signal with the first internal time to form a suspected water leakage time series signal; and match the signal detected by the second detection device within the second internal time with the second internal time to form a paired time series signal; determine Whether the paired time series signal and the suspected water leakage time series signal can be paired. When it cannot be matched, the suspected water leakage signal is determined to be an error signal and is not processed. When it can be matched, the suspected water leakage time series signal and the matching time are used. The time difference of sequence signals locates the location of water leakage. The invention reduces the false alarm probability of the water leakage signal, improves the reliability of the system, and solves the problem of high false alarm probability of the water leakage signal in the prior art.

Description

technical field [0001] The invention relates to the technical field of pipeline leak location, in particular to a pipeline leak location method and system. Background technique [0002] Water supply pipelines play an extremely critical role in long-distance water resources transportation, but because most of the pipelines are laid in harsh natural environments such as the wild or underground, they are easily damaged. Once the water supply pipeline is damaged and leaks occur, timely maintenance of the pipeline is required to avoid additional economic losses. Therefore, the rapid detection and location of pipeline leakage has great application value and can provide program guidance for pipeline maintenance. [0003] At present, for the signal location method of pipeline leakage in the water supply network, most of them use signal processing methods to extract information about the leakage signal from the mixed signal obtained by the pipeline, and realize the leakage according...
