Pressure water pipeline leakage detection/monitoring system and method and medium

Abstract

The invention provides a pressure water conveying pipeline leakage detection/monitoring system and method and a medium. The system comprises a sensing device used for sensing leakage noise of a water conveying pipeline; a data acquisition module used for receiving the leakage noise sensed by the sensing device and converting the leakage noise into a leakage noise digital signal; a central server which receives the leakage noise digital signal fed back by the data acquisition module, analyzes the received leakage noise digital signal, judges whether the water pipeline leaks or not through calculation and analysis, and locates the position of a leakage noise source according to an analysis result, namely, determines the position of a leakage point, and calculates the leakage amount at the leakage point; meanwhile, the central server sends a control instruction to the data acquisition module so that the leakage of the pressure water conveying pipeline is detected or monitored. According to the invention, the leakage noise of the pipeline is detected/monitored, the position of the noise source is accurately positioned by using a traceability tracking method, and the intensity of the noise source is calculated, so that the leakage detection/monitoring purpose is achieved.

Description

technical field [0001] The invention relates to the field of safety detection / monitoring of pressure water pipelines, in particular to a source tracing method, system and medium for pressure water pipeline leakage detection / monitoring. Background technique [0002] Leakage is common in both long-distance large-scale pressure water pipelines and urban tap water pipe networks in China. Leakage not only causes waste of precious water resources, but also causes serious accidents such as ground subsidence and pipe burst due to hazardous concentrated leakage, causing huge property losses and even casualties, affecting social harmony and stability. [0003] At present, for large-scale buried pressure water pipelines at home and abroad, the method of regularly stopping water for maintenance is mainly used to search for diseases such as leakage to prevent the occurrence of pipe burst accidents caused by harmful concentrated leakage. Due to the long intervals between water interrup...

Problems solved by technology

Due to the large amount of traffic in the city, the noisy environment, the interlacing of various pipe networks, and the different depths of burial, only a part of the leaks with shallow burial and large leakage can be found by hearing leaks, and the detection sensitivity, positioning accuracy and anti-interference abilit
