The Fast Calculation Of Water Supply Networks & Research On Its Drawing Automatization

The optimization system of water supply networks is very complicated. Because of the huge investment and management cost, optimal rehabilitation can save much money and actualize good economic and social situation.Aimming at the comprehensive information in water supply networks design process, based on AutoCad2004, This paper developes cad with the professional knowledge. This paper also introduces mathematics model and calculation method of optimization later, which establishes the foundation of networks system programming.In the process of optimal design of water supply networks, this paper puts forward a new method which processes network optimization by basic related matrix, including node demand calculation, initial flow distribution, and finally optimization. In data processing, this paper introduce a method based on automated created identification matrix and coefficient matrix through data transformation which can raise the efficiency of work .In the networks' system drawing process, based on the data from optimal design, we can design the drawing interface through VBA which has a merit of good interface. Based on the result of optimal design, this paper puts forward a new method drawing isopiestic line. This paper make full use of the computation ability of VBA and the drawing advantages of AutoCAD, it reaches the goal of optimal design of water supply networks and drawing unification.
