Embodiment Construction

[0029] The invention utilizes a "multi-probe correlation tester", installs the probes of the tester on the pipe network, collects sound wave data, and then determines the location of water leakage. The multi-probe correlation tester can use Enigma high-sensitivity digital multi-probe correlator. Two probes can determine the location of leaks, and multi-probes can be used to conduct general surveys conveniently, and the detection efficiency is very high.

[0030] The detection is divided into two steps, that is, first to determine whether there is a water leakage fault, and then to determine where the water leakage point is.

[0031] The probe can be conveniently placed on the pipeline valve, fire hydrant and pipe body, as long as the probe is in close contact at the place where it is placed.

[0032] The probes used by the tester are generally divided into two types, namely acceleration sensors and water sensors. Acceleration sensors are placed on pipeline valves, fire hydra...

Abstract

An underground water supply network water leakage detecting method utilizes a multi-probe dependence tester, and probes of the tester are installed on a pipe network to collect the sound wave data. The method comprises the following steps: a. the probes are installed a pipe network valve, a hydrant or a water meter at internals, and the probes are closely contacted with the pipe network valve, the hydrant or the water meter; b. the sound wave data is collected; c. whether water leakage fault occurs is judged by analyzing the data. By utilizing function relevant principle, the method can calculate the position of water leakage point just by collecting the sound wave data at two points, thus having high locating efficiency; regional water leakage general investigation can be completed by testing for once, the data is easy to store, and the accident analysis can be conveniently carried out; as the data can be automatically collected, recorded and processed, the working intensity and anthropogenic influence can be greatly reduced.

Description

technical field [0001] The invention relates to a method for measuring water leakage points of a water supply pipe network by using sound waves, belonging to the technical field of measurement. Background technique [0002] Urban water supply is an important part of urban public utilities. There are complex water supply pipe network systems distributed underground in every city. Due to long-term damage or accidental damage, leakage accidents will inevitably occur in the pipe network, and how to find them in time To the point of water leakage is the main business content of the water supply department. Nowadays, the detection of water leakage mainly relies on the human ear to listen to the sound, that is, to use a listening stick or an electronic listening stick to completely rely on the hearing of the human ear to determine whether there is a sound of water leakage. Therefore, it is greatly influenced by factors such as people's psychology, work attitude, hearing and people...
