A method for optimal layout of pressure monitoring points in municipal water supply network

Abstract

A method for optimizing the arrangement of pressure monitoring points in municipal water supply pipe networks, based on EPANET software to simulate the operation status of water supply pipe networks in the monitoring area, and obtain the spatial attributes and non-spatial attributes of each pressure monitoring point; use the above attribute values ​​to construct the pipe network The original characteristic matrix data of each node is processed through dimensionless to obtain the node characteristic matrix data; the OPTICS clustering algorithm is used to realize the cluster analysis of the node characteristic matrix data, and an ordered set of pressure monitoring nodes is obtained; based on the ordered set of pressure monitoring nodes , select an appropriate node clustering set, and finally determine the location and number of pressure monitoring points in the monitoring area of ​​the municipal water supply network according to the clustering results and the degree of influence of the nodes. The invention has the advantages of: it can effectively reflect the regional distribution of the pipe network pressure; the use of the OPTICS algorithm does not need to initially set the number of divided clusters, and the shape of the clusters can be any shape, which avoids the impact of the initial parameters on the clustering results. Impact.

Description

technical field [0001] The invention relates to the field of municipal water supply pipe network equipment, in particular to a method for optimally arranging pressure monitoring points of the municipal water supply pipe network. Background technique [0002] The municipal water supply network is an important infrastructure to ensure a city's economic development and living standards, and is the lifeline of a city's survival and development. However, due to the continuous expansion of water consumption and the increase in the service life of the pipe network, there is a lack of a modern, intelligent, and theoretical municipal water supply pipe network management system, and the municipal water supply pipe network has gradually exposed a wide range of leakage. , will cause waste of water resources and economic losses. [0003] With the development of science and technology and the continuous improvement of water supply requirements, the establishment of a water supply pipe ne...
