Abstract

The invention discloses a water supply pipeline leakage loss monitoring and leakage positioning method and system. The method comprises the following steps that a whole water supply pipe network areais partitioned in a closed mode, a multifunctional leakage monitor and a remote water meter at the front end of the water supply pipe network are used for monitoring flow, pressure and water consumption indexes of all partitions, and then a metering model algorithm is used for conducting partition leakage metering; noise data in the water supply pipe network is acquired in real time by using noiserecorders arranged in each partion of the water supply pipe network, and a leakage pipe section is determined by using a frequency spectrum filtering and frequency spectrum comparison method; the noise recorders are installed at the two ends of the leakage pipe partition respectively, and noise data are further collected to achieve positioning of leakage points. A systematic monitoring means frompartitioned leakage monitoring to suspected leakage pipe section positioning and then to specific leakage point positioning is realized. According to the method, the whole area is broken up into parts, and management and control of leakage of the water supply pipe network are achieved through a small number of devices in a face-to-line mode and a line-to-point mode.

Description

technical field [0001] The present application relates to the technical field of sensor monitoring, in particular to a water supply pipeline leakage monitoring and leakage location method and system. Background technique [0002] Underground pipelines are important urban infrastructure and an important basis for ensuring the normal operation of urban production and life. As a kind of pipeline that was built earlier in the urban underground pipeline network, the water supply pipeline network in many cities has already experienced aging phenomena. Security risks. Although there are some pipeline leak detection equipment on the market, the effect is not ideal. [0003] The current pipeline network leak detection is still mainly in the form of manual inspection. On-site use of listening rods, electronic leak detectors or related instruments to find leak points requires high experience of testing personnel, high personnel input costs and time-effective Poor positioning, slow p...
