Management system combining secondary water supply with DMA leakage loss management

Abstract

The invention relates to a management system combining secondary water supply with DMA leakage loss management. Data of a GIS system, SCADA system, business charge system and the like can be integrated for comprehensively displaying the secondary water supply and DMA production and sale differences. Functions include the secondary water supply and DMA partition overview, DMA community production and sale difference analysis, secondary water supply management of a DMA community and abnormal alarming of water pressure and water quality. The provided management system combining the secondary water supply with the DMA leakage loss management overcomes the defect that existing secondary water supply management and DMA leakage loss management are both functionally separated and are independent;management functions of the two parts are organically combined, a flow monitoring value in the secondary water supply is used in third-level analysis of the DMA community, and a pressure monitoring value in the secondary water supply is used in evaluation of DMA community leakage loss analysis. Under the condition of satisfying normal water use of the community, the pipe network leakage loss rateof the community is gradually decreased.

Description

technical field [0001] The invention relates to a management system, in particular to a management system combining secondary water supply and DMA leakage management. Background technique [0002] DMA: (District Metering Area (independent metering area)); DMA zoning management is one of the effective methods to control water loss in urban water supply systems. Its concept was first proposed by the British Water Industry Association at its Water Affairs Joint Conference in early 1980. In the report, DMA is defined as an independent area in the water supply and distribution system that is cut and separated, usually by closing valves or installing flow meters to form a virtual or actual independent area. By measuring the amount of water entering or leaving this area, and analyzing the flow rate to quantify the leakage level, it is helpful for leak detectors to more accurately decide when and where it is more beneficial to detect leaks, and to carry out active leakage control. ...

AI Technical Summary

Problems solved by technology

Due to the continuous development of the secondary water supply towards unified management and construction, the water department urgently needs an effective supervision platform to manage the secondary water supply; the leakage rate of the pipeline network remains high, and the solution to the leakage problem of the pipeline network is very complicated, especially It is more difficult to find and solve the leakage of pipe network inside the community

With the continuous development of smart water affairs, some intelligent management platforms have gradually appeared in the market, which have solved some application problems for water companies, but so far, none of them has combined secondary water supply and DMA community leakage management. integrated management system

From the business level of the water company, the two parts are generally consistent in geographical scope and can be said to complement each other. This kind of business separation is not very ideal in terms of management or application.
