Research of Urban Water Supply Pipe Network Geographic Information System Processing of Pipe Burst Accident

摘要

Using geographic information system of urban water supply networks for processing tube rupture accident can repair in time, reduce losses, provide scientific management of analysis and policy decision function for water supply company. In this paper, research the logical network, pipe burst detection, valve-turnoff analysis and so on. It establishes logical network at first, bases on the basic principles of graph theory, constructs Pipe Network Models, and uses adjacency list storing data, then it comes to pipe burst detection, uses flow balance method to establish detection model, discussion and analysis of this model. And finally is valve-turnoff analysis, using breadth-first traversal algorithm and recursive function theory, formulating shut-off valve program, expanding the analysis of valve-turnoff analysis and affecting user's analysis, and giving specific examples.
