The design of water supply network based on GIS

Water supply pipeline network is a system which has a large of spatial attribute data. In order to improve the manage and work efficiency, reducing the workload of workers, the best way is that designing a water supply network based on GIS, the system based on Arc GIS platform, using Client-Server and Browser-Server model to form a new composite model to set up the system. The paper introduces every function and the key technology of this system in detail, such as seamless integration of GIS of water supply pipeline network and hydraulic model which based on building pipeline network concise model dynamic and use the hydraulic calculation function to guarantee the authenticity of hydraulic model, hydraulic model which can help to simulate the whole system and analyze the condition of pipeline network, the model of pipe blowout statistical can help operator to know the condition of water pipe every segment in the system and forecast the events of pipe blowout, and according to the requirements of system, the fast locating algorithm was modified to reduce the time of searching objects. All these important technologies can strengthen the security, improve the speed of locating objects and help operator to analyze the pipeline condition. The system was tested in the laboratory environment and ran successfully, because it accords with the requirements of water supply network.
