To achieve real-time monitor and control of the water supply remote monitoring terminal and the management of other information(data of other water supply equipment); this paper introduces the design of a remote monitoring system for water supply pipe network with .NET development platform, on the basis of various key technologies such as GIS, database, data communication, multi-threaded design etc. The system adopts multi-layer architecture design framework to achieve the scientific, dynamic visual management of water well. By running the software on-site verifies the reasonableness of design and the stability of operation and provides a feasible solution for the automation management of the water supply network.
