An evaluation system for pressure regulation and leakage reduction of urban water supply network

Abstract

The invention discloses an evaluation system for pressure regulation and leakage reduction of urban water supply pipe networks. The system of the present invention comprises a monitoring module of a lower computer, a wireless communication module and a data receiving and evaluating module of an upper computer. The monitoring module of the lower computer is signal-connected with the data receiving and evaluating module of the upper computer through the wireless communication module. The lower computer adopts the operation scheme of alternating pressure regulation, and the evaluation of the upper computer comprehensively considers the characteristics of the average value, median value, and cumulative probability distribution of flow and pressure. Compared with the prior art, the present invention has the advantages of unattended automatic operation, convenient remote setting of pressure control schemes, elimination of interference from work and rest days, weather, etc. on users' water consumption, and improved comprehensiveness and scientificity of effect analysis.

Description

technical field [0001] The invention belongs to the field of leakage reduction of urban water supply pipe networks, and in particular relates to an operation evaluation system for intelligently adjusting pipe network pressure and reducing leakage. Background technique [0002] With the advancement of urbanization and the expansion of city scale, the water supply volume of urban water supply pipe network is increasing day by day. Under the premise of ensuring the safety of water supply, improving water supply efficiency has good economic benefits, and has become the focus of various water companies. As a technical means to improve water supply efficiency, rationally adjusting the operating pressure of the pipe network can reduce pipe network leakage, protect pipe materials, and reduce the gap between production and sales. [0003] How to scientifically analyze the operation effect of pressure regulation and leakage reduction, the current general method is to record the minim...

Problems solved by technology

The limitations of this method are: the integrity of the method is not strong, it is difficult to flexibly carry out diverse research on the technical field of pipeline network leakage reduction; when the pipeline network leakage loss is small, the reliability of the minimum night flow count is not high, Some water companies even had to send specialists to carry out manual recording in the middle of the night, which was inefficient; when the daily pressure was adjusted in different periods, the minimum nighttime flow could hardly represent the leakage throughout the day; it was difficult to rule out the influence of seasons, weather, holidays, etc. on water consumption interference factors
