Automatic multi-level zoning method for water supply pipe network

Abstract

The invention discloses an automatic multi-level zoning method for a water supply pipe network. The method comprises the steps: firstly, partitioning a subzone system, wherein a water supply system is composed of a plurality of units, a zone which is directly connected with water tanks and water pumps is called a first-level subzone system, multi-level subzone systems are partitioned based on the first-level subzone system, and each subzone serves as a node; carrying out calculation by an evaluation function of an automatic multi-level zoning algorithm, and gradually merging the quantity of the subzones from more to less, wherein an N-level zone appears when a certain stage is merged, and a larger-scale N-1-level zone appears when a certain stage is merged again until a first-level zone is completed. According to the method, the pipe network is subjected to multi-level zoned water supply, the water supply pressure of the pipe network can be balanced, pipe bursting can be reduced, and leakage loss can be lowered; meanwhile, water quality can be improved, water supply enterprises can conveniently manage each zone, and the level of service of water supply is increased.

Description

technical field [0001] The invention relates to the field of water supply pipe network operation management, and more specifically, relates to a multi-level automatic partitioning method for a water supply pipe network. Background technique [0002] In recent years, due to the continuous migration of residents to cities, the scale of cities has continued to grow, and urban water consumption has continued to increase. According to statistics, by 2025, about 300 million people will migrate to cities, which is equivalent to the total population of the United States. The water supply network system is insufficient to meet the needs of future population growth. In addition, due to the insufficient planning of the urban pipe network, coupled with the continuous aging of the pipe network, the pressure distribution of the pipe network is uneven, and pipe burst accidents occur frequently, which poses a severe challenge to the safety of the city's existing water supply pipe network. ...

Problems solved by technology

[0003] The traditional zoning method of the urban water supply network system is based on manual experience, which cannot realize automatic zoning. The zoning is often unreasonable, which may easily lead to insufficient water supply in some areas, and at the same time cause the water pumps in the pumping station to fail to operate in the high-efficiency section and generate energy. wasteful situation
