Accurately positioning water leakage point of underground water pipe

Abstract

The invention provides a system for accurately positioning a water leakage point of an underground water pipe, and relates to the technical field of intelligent pipe networks. The system comprises a data collection module, a curve generation module, a leakage judgment module, a first processing module, a second processing module and a third processing module, wherein the data collection module used for detecting the real-time water flow, real-time vibration signals and real-time sound wave signals of a pipe section inlet and a pipe section outlet; the curve generation module is used for generating a vibration signal curve and a sound wave signal curve; the leakage judgment module is used for outputting a leakage judgment result when the flow difference value between the pipe section inletand the pipe section outlet of each pipe section is larger than a preset flow threshold value; the first processing module is used for processing according to the leakage judgment result to obtain average delay time caused by a leakage point; the second processing module is used for matching in a preset corresponding relation table according to the leakage judgment result and the attribute parameters to obtain a signal propagation rate; and the third processing module is used for calculating the distance between the leakage point and the pipe section inlet and the distance between the leakagepoint and the pipe section outlet of the leakage pipe section according to the average delay time and the signal propagation rate. According to the system, the accuracy of leakage point positioning iseffectively improved.

Description

technical field [0001] The invention relates to the technical field of intelligent pipe networks, in particular to a system for precisely locating leaking points of underground water pipes. Background technique [0002] As one of the urban public infrastructure, underground water pipes are responsible for delivering pressure water heads to various water nodes, and play a pivotal role in ensuring the improvement of people's living standards, the stable development of the urban economy, and social stability. During the operation of underground water pipes, leakage will inevitably occur due to man-made or natural reasons such as pipe quality, construction quality, corrosion, and aging. The leakage of the underground pipe network, on the one hand, causes a waste of water resources, and on the other hand, affects the quality of life and cost of living of residents. How to control and reduce the leakage of the water supply pipeline, locate the location of the leakage in time, red...

Problems solved by technology

[0003] In the existing technology, manual inspection is mainly used to find leaks and locate leaks through basic equipment such as leak detection sticks, electronic leak detectors, and impact drills. Not only is it difficult to find leaks in time, but it also causes waste of manpower and material resources. Water supply cannot be effectively guaranteed, affecting the safety of drinking water
