Pipeline leakage positioning method and system

Abstract

The invention relates to a pipeline leakage positioning method and system. The method comprises the steps that two detection devices for collecting pipeline signals are arranged on a pipeline at a certain interval; internal time of the two detection devices are synchronized to the Beidou satellite reference time; a suspected water leakage signal is matched with first internal time, and a suspectedwater leakage time sequence signal is formed; a signal detected by the second detection device in the second internal time is matched with the second internal time to form a pairing time sequence signal; and whether the pairing time sequence signal and the suspected water leakage time sequence signal can be paired or not is judged, it is judged that the suspected water leakage signal is an errorsignal and processing is not carried out if the pairing time sequence signal and the suspected water leakage time sequence signal cannot be paired, and the water leakage position is positioned throughthe time difference between the suspected water leakage time sequence signal and the pairing time sequence signal if the pairing time sequence signal and the suspected water leakage time sequence signal can be paired. By means of the pipeline leakage positioning method and system, the false alarm probability of the water leakage signal is reduced, the reliability of the system is improved, and the problem of the high false alarm probability of the water leakage signal in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of pipeline leakage location, in particular to a pipeline leakage location method and system thereof. Background technique [0002] Water supply pipelines play an extremely critical role in long-distance water resource transportation, but most pipelines are easily damaged because they are laid in harsh natural environments such as the wild or underground. Once the water supply pipeline is damaged and leaks, it is necessary to repair the pipeline in time 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 the signal processing methods are used to extract the information about the leakage signal from the mixed signal obtained from the pipeline, and realize the leakage ...
