Design And Implementation Of Water Supply Pipe Network Leakage Analysis And Processing System Based On GIS

Water is the lifeblood of a human, it is indispensable to safeguard life and production material basis, is the important factor of the human society progress and sustainable development, can guarantee the safe operation of water supply system, directly related to the urban construction and economic development. Can network as an important part of water supply system, safe and smooth operation will directly social benefit and economic benefit of urban water supply. In urban water supply pipe network in the operation of the system, Water supply network system of database design is the core content of system development and design, in view of the current most of the water supply network geographic information system design in the analysis of the deficiency of network space, combined with the characteristics of water supply network data, establish a more suitable for analysis of the management of water supply network system of data model, the object-oriented Geodatabase, geographical data model for water supply network integration management of spatial data and attribute data, and complete the data structure design of water supply network. To build an open, interactive 3 d the underground water supply network model.Water supply network data preprocessing and the database design is to build a good water supply pipe network information system is the basis and premise, and the seepage analysis is one important spatial analysis functions of GIS of water supply pipe. This paper discusses the leakage occurs, the need for analysis, the main task of the paint theory model of seepage analysis, analysis of the parent and child nodes in the tree pipe network, the properties of designed to generate data structure of the longitudinal profile. Topological relationship between the various valves in water supply network analysis, on this basis, the finished water supply pipe network leakage valve analysis algorithm implementation.System USES the c# programming language and Arc Engine component library, based on Microsoft Visual Studio2005 design platform, for the design of the interface and function, realizes the urban water supply network system of graphics operations, conditions, query, spatial measurement, map display, seepage analysis, attribute editor, logo printing, etc. Are summarized and the research results and problem, put forward the possible problems about system in practical application.
