| 摘 要： | 介绍了一个管网建模系统的设计。针对管网建模时的绘图需要和一些特殊约束条件，在需求分析的基础上，对主要的功能算法进行了设计和描述，并给出了使用本系统进行建模的步骤和一个管网模型实例。该系统不但具有图形编辑软件常用的编辑功能，而且与工程实际相结合，能够有效地提高管网建模的效率，满足工程中管网图形可视化建模的需要。整个管网建模系统采用面向对象的程序设计思想进行设计，稍加扩展即可以作为管网水力计算软件的输入子系统使用。

| Abstract: | The design of a modeling system for pipe net is proposed. Based on the requirement analysis, including plotting requirements and some special restrictions when modeling, several main algorithms are designed and described. The modeling steps using this system and a finished example are also described. The pipe net modeling efficiency is improved effectively and the visual modeling needs of pipe net are satisfied. Because it not only has usual edit functions, but also accord with the engineering facts. This system is designed with object oriented programming technology, so it is easily extended as the input sub system of water power computing software. |
