The Research Of System Simulation Of The Water Supply Network In Zhengzhou

System simulation of water supply pipe network is trend of development of pipe network construction at the present time, Due to starting than night, the system is in development and perfect stage now. Drawing lessons from Liaoning Technical University research technique of ventilation of coal pits simulation and fluid network, combining the pipe network modeling project of Zhengzhou, Discussing the basic theories of simulation modeling of the pipe network in detail. And has done exhaustive planning of the administrative system of pipe network based on GIS system of construction in Zhengzhou. Using the improved seasonal exponential smoothing to finish the prediction of water consumption of Zhengzhou at the same time. Put forward through a new thinking of setting up BP nerve network model to confirm drag coefficient of water supply pipe network. And make this model reach the ability to confirm drag coefficient through training, to make the satisfactory result and achieve the goal of studying. Enriched the theory of the simulation system of the water supply pipe network to a certain extent, to solve the theory difficult point of system simulation of water supply pipe network--the determination of the drag coefficient, has offered another brand-new means.
