基于Matlab的GUI绘制给水管网等压线和三维水压面

Plotting 2-D and 3-D Contour of Water Pressure in Water Distribution Network Based on Matlab's GUI

为了解供水管网的工作状况并控制管网运行,需进行管网等压线和三维水压面的绘制。为此利用Matlab软件的矩阵计算和绘图功能,通过管网平差计算结果即管网中各节点的水压值绘制了等压线和三维水压面;并对GUI(Graphical User Interface,图形用户界面)的界面程序进行了二次开发,实现了给水管网水力计算图的绘制。将该方法用于某多水源管网的水力计算及管网等压线和三维水压面的绘制,结果表明该算法具有简单可靠、易于实现、直观易懂的优点。

In order to comprehend the working condition of water distribution network and to control the whole working process, there is need to acquire the 2-D and 3-D contour of water pressure in the network. Therefore, according to the nodal pressure data from the hydraulic analysis results of the network, 2-D and 3-D contour of water pressure was plotted based on the Matlab＇ s toolkit of matrix calculation and plotting. Even more, an interfacial programming for water distribution system with Graphical User Interface （GUI） was built. Users can draw hydraulic calculating map of water distribution system in the programming interface. With the presentation of a sample network, it is proved to be a concise and an easy way to illustrate the hydraulic state of the water distribution network.
