A water supply pipeline leakage monitoring and leakage location method and system

Abstract

This application discloses a method and system for water supply pipeline leakage monitoring and leakage location. The method includes the following steps: divide the entire water supply pipeline area into closed areas, and use the multifunctional leakage monitor and remote water meter at the front end of the water supply pipeline network Monitor the flow, pressure and water consumption indicators of each zone, and then use the metering model algorithm to measure the leakage of the zone; use the noise recorder installed in each zone of the water supply network to collect real-time noise data in the water supply network, and use spectrum filtering and spectrum ratio To determine the leaking pipe section; install noise recorders at both ends of the leaking pipe section, and further collect noise data to locate the leak point. A systematic monitoring method has been realized from the area leakage monitoring to the location of the suspected leakage pipe section, and then to the location of the specific leakage point. This method divides the entire area into parts, and realizes the management and control of the leakage of the water supply pipe network with a small amount of equipment in a manner from surface to line and from line to point.

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...
