低压台区地理图到电气接线图的自动转换

Conversion from GIS maps to electric diagrams in low voltage transformer areas

对台区电气接线图的绘制需求进行了分析,提出了将台区地理图自动转换成电气接线图的技术思路,并重点对图标的分层绘制、水平居中对齐的调整、增量绘制等关键问题进行了阐述。所提出的算法在一种基于GDI+技术的绘图工具中得到了实现。利用该算法,目前已经完成了江西九江城区600余台区低压电气接线图的自动绘制工作。应用表明,所提出的方案与算法切实可行,所得到的电气接线图布局均匀、美观、实用。

The paper analyses drawing requirements of electric diagrams in low voltage transformer areas,then puts forward the idea of automatic conversion from GIS maps to electric diagrams.Key issues including layering drawing,horizontal centering alignment and incremental drawing are elaborated in detail.These algorithms are carried out in a drawing tool based on GDI＋.More than 600 electric line diagrams of low voltage transformer areas in Jiujiang city,Jiangxi province have been completed automatically through the algorithms.The application manifests that the proposed algorithms operate well.The generated electric diagrams are well-distributed,beautiful and practical.
