A Method for Layout of Pressure Monitoring Points in Water Supply Pipeline Networks Oriented to Burst Monitoring

Abstract

The invention discloses a method for arranging pressure monitoring points of a water supply pipe network oriented to pipe burst monitoring, which uses a clustering method based on space density and noise points to analyze the node pressure sensitivity matrix of the pipe network under normal and pipe burst conditions , carry out node clustering, divide the monitoring area of ​​the pipe network, and pay attention to the generated noise points, and then use the improved strength Pareto evolution algorithm based on the reference vector to solve the optimal layout model of the pressure monitoring points of the water supply pipe network, and generate more feasible The solution space, considering the repetition and cluster coverage of the monitoring points and the noise points of the pipe bursting condition, obtains the final layout of the monitoring points. The method of the invention combines a clustering algorithm with an optimization algorithm, compares and analyzes two working conditions, normal and burst, and fully considers the particularity of clustering noise points, so that the water supply pipe network can be monitored more comprehensively.

Description

technical field [0001] The invention belongs to the field of arrangement of pressure monitoring points of a water supply pipe network, and relates to a method for arranging pressure monitoring points based on node clustering of a water supply pipe network and facing pipe burst monitoring. Background technique [0002] The water supply pipe network is the pipeline system for delivering and distributing water to users in water supply projects. Explosion of pipes will not only cause waste of water resources and reduce economic benefits of water supply enterprises, but also have negative impacts on residents’ lives and social production. How to detect pipe bursts in time It is an urgent problem to be solved to send maintenance personnel to reduce losses, and even find abnormal pressure fluctuations before the pipe bursts to maintain in advance. Water supply network pressure monitoring is the most direct and effective way to understand the operation status of the pipe network. Pi...
