Assessment method for leakage detecting effect of leakage point

Abstract

The invention discloses an assessment method for the leakage detecting effect of a leakage point. The assessment method comprises the following steps of: collecting dim leakage point information, andpre-processing the collected dim leakage point information; determining a leakage point growth function; determining dim leakage points and background leakage points according to the leakage point growth function; calculating number of dim leakage points and background leakage points in different leakage detecting periods; calculating a leakage detecting coefficient which is equal to number of dimleakage points / sum of number of the dim leakage points and number of the background leakage points, and calculating an average leakage detecting coefficient P of a historical leakage detecting period; assessing the leakage detecting effect of different leakage detecting periods; indicating that the leakage detecting working effect is good if the leakage detecting coefficient in the this-time leakage detecting period is higher than P; and indicating that the leakage detecting working effect is poor if the leakage detecting coefficient is lower than P. The method disclosed by the invention further comprises calculating a leakage point distribution condition in different areas, assessing the leakage detecting effect of different areas, predicating the number of leakage points which possiblyexist in next leakage detecting period, and making a leakage detecting working plan.

Description

technical field [0001] The invention belongs to the field of leak detection of urban water supply pipe networks, and in particular relates to a method for evaluating leak detection efficiency of leak points. Background technique [0002] Leakage in pipe networks is a constant challenge for water utilities all over the world. Leakage problems reduce service levels for water utilities and municipalities, with multiple implications for infrastructure systems, the natural environment, and the water utility's financial well-being. Therefore, more and more advanced leak detection instruments, scientific pipe network management technology, fine pipe network pressure regulation methods and other measures have been introduced into the pipe network leakage control. These technologies and measures play a significant role in reducing pipe network leakage. played an important role. [0003] However, there is still a lack of uniform standards in the leakage evaluation method, resulting ...

Problems solved by technology

At present, most water companies or leak detection companies use empirical methods to evaluate leak detection work, which lacks scientific and effective theoretical guidance, making leak detection work inefficient

[0005] In each leak detection cycle, the leaks discovered by the leak detection workers only account for a part, and there are still a large number of leaks that can be detected by existing technologies that have not been discovered. strategies and many other factors
