Urban water supply pipe network is an important part of municipal infrastructure systems, is the basis for the survival and development of the city. How to guarantee the safety operation of the water supply pipe network, to reduce water supply pipe network leakage rate, to prevent explosion occurred, and fundamentally improve the water supply pipe network operation management level, become the water supply enterprise high attention and urgent problem to be solved. Therefore, this paper studies monitoring system of water supply pipe network based on GPRS. First, the characteristics and the importance of the water supply pipe network, so using GPRS technology. Then, detailing the characteristics and advantages of GPRS technology. Secondly, introduces the composition of the urban water supply pipe network monitoring system. Finally, the realization of specific functions will be described. Application of monitoring system for real-time monitoring, fully guaranteed the security of the water supply system.

Due to urban overcrowding, the population density of residential areas and water use per unit are increasing. Therefore, it is necessary to study the flow of water supplied to cities and to improve the healthy circulation of urban water. This study used Modelica, a non-causal analytical program. Using Open Modelica, the researchers constructed a model linking water distribution and sewerage, as the basis of a balanced urban water model. Using the programmer's toolkit provided by EPA-NET and EPA-SWMM, which are commonly used to simulate the existing water supply and sewage pipe networks, Open Modelica-based water distribution networks and sewage pipe networks can be connected and simulated based on the customer block. A model was built so that 90% of the hourly water consumption supplied to the water supply pipe network can be automatically introduced into the sewage pipe network. If a matching table is constructed to connect the nodes of the water supply pipe network and the sewer pipe network, the nodes will reflect in the graphical user interface (GUI) developed in Open Modelica. It was developed to enable modification of links, pumps, tanks, and valves. The 48-hour water supply was simulated using the developed model, and it was confirmed that water supply and sewage networks were successfully connected. In the future, we plan to develop a more expanded and realistic urban water circulation model by considering additional urban water circulation factors, such as sewage treatment, water reuse, rainwater use, storm runoff, and low-impact development facilities. Through this study, it was confirmed that Modelica can simulate changes in the system over time. Since it is a formula-based non-causal simulation language, it is possible to establish and reuse relationships between blocks through block-by-block development of urban water circulation elements. It is expected to contribute to the visualization and concretization of future urban water circulation models.

Using GIS to analysis urban water supply pipeline network characteristic, it can make full use of GIS spatial data management and graphics processing advantages. This paper is on the basis of clarified the importance of the dynamic characteristics, it include three aspects of research. First, topological graph modeling, establishes the section between the nodes and directed graph, and uses adjacency list to store; Second, spatial database structure, it designed by the topography and galleries, some data sets, the line data set, the surface data and document data sets of pipe network GIS spatial data structure; Third, nodal flow dynamic characteristics, analysis of node flow of small changes ,which can lead to node pressure and the change in the flow section, and build the mathematical model. In this paper, the research contents to ensure the security of urban water supply, improve the level of urban management information, improve emergency management capability of urban is of great significance.
