【摘要】 给水管网优化系统是一个比较复杂的系统，投资大、管理费用高，经济合理的进行管网设计不仅可以节省大量的资金，而且能够产生巨大的经济效益和社会效益。本文针对给水管网设计过程中繁多的管网综合信息，基于AutoCAD2004平台，融进给水管网设计专业知识进行CAD二次开发。随后介绍了给水管网实用优化设计的数学模型和求解方法，为管网系统的规划奠定了坚实的基础。在管网优化计算中，文章提出利用基本关系矩阵进行大型复杂管网优化设计的新方法，包括管网节点流量的计算、管段流量的初始分配和管网的优化计算。在数据的处理上，通过数据转换自动生成管段识别矩阵和初分流量的系数矩阵，大大提高了工作效率。在绘制管网系统图方面，充分利用AutoCAD的开发工具VBA来设计管网绘图界面，具有绘图界面友好的特点。最后在计算结果的基础上绘制给水等压线。本文充分利用了VBA的计算功能和AutoCAD的绘图优势，实现了给水管网优化设计和绘图一体化。更多还原

【Abstract】 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.更多还原
