燃气管网水力计算图的计算机生成

首先对直接驱动绘图机绘图的缺点及自动绘图的优点进行了叙述 ,接着对使用AutoLISP技术自动生成燃气管网水力计算图的方法、特点进行了详细的探讨 ,最后以一工程为例 ,对该自动生成燃气管网水力计算图方法进行了更为详尽地阐述。首先采用管网拓扑结构数据形成管网拓扑结构图层 ,然后与水力计算数据文件耦合形成完整水力计算结果图层。首次利用LISP语言开发了燃气管网水力计算图自动生成程序。

The computer forming method of the waterpower calculation drawing in gas networks

The shortcomings of the direct driven graph plotter and the excellence of automatical drawing were firstly narrated. Then, the method of forming the gas network drawings using AutoLISP technology, which was put forward in this paper, and its characteristics were discussed in detail Finally, the method was expatiated further using an engineering example. A topology structure drawing layer was generated according to the topology structure data. Then by coupling with the result of waterpower calculation, a full drawing layer is formed. The program, which is used to draw the waterpower calculation drawing in gas networks automatically, is written in LISP language for the first time.
