Abstract

To address the issues of insufficient information technology in the water supply network and how to quickly develop effective valve closure plans for travel in the event of pipe bursts, the visualization management of the water supply network has been achieved, the layout of the water supply network pipeline has been optimized, and the problem of graphic information asymmetry has been solved. By using the principles of graph theory, the water supply network is abstracted as a two-dimensional directed network graph; Establish a three-dimensional network model of water supply network based on GIS technology, and create a spatial database to store graphic data; This article's algorithm is applicable to the analysis of complex water supply pipe bursts in circular pipe networks. It studies and implements an algorithm for quickly locating the upstream/downstream valves that need to be closed, the range of affected areas after downstream pipe bursts occur, and a comprehensive valve closure analysis algorithm.A solution for the burst analysis algorithm of 3DGIS based on real pipeline network data scenarios has been demonstrated and developed, realizing functions such as dynamic graphic burst analysis, connectivity analysis, and valve closure analysis. GIS services have been published, and users can connect front-end and back-end graphic data and attributes and update them dynamically in real-time.
