Embodiment 2

[0102] Embodiment 2 of a vector graphics conversion method provided by the present invention includes three major modules: SVG file analysis module SVGParser, which analyzes SVG graphic element nodes and graphic nodes; G graphic metafile generation module GElementConverter, which generates classified and layered G Language metafile sequence set; G graphics file generation module GDisplayConverter, which generates G language graphics files, and at the same time generates a signal forwarding point table corresponding to the graphics, which is used as a data source for remote browsing data refresh. Its specific graphic conversion frame diagram is as follows Figure 5 As shown, the input of this method is an SVG graphic file, and the output is a classified and hierarchical G language metafile sequence set, a G language graphic file and a signal forwarding point table.

[0103] The primitives are composed of basic graphic elements: line segment, rectangle, ellipse, circle, polyline...

Abstract

The invention provides a conversion method for vector graphics of a transformer substation. A graphics file in a scalable vector graphics (SVG) format supported by a monitoring system of the transformer substation is converted into a graphics file in a G language format adopted by an intelligent scheduling system. The method is characterized by comprising the following steps of: 1, resolving an SVG graphics file, and analyzing each power device layer node, wherein the power device layer nodes are SVG graphics nodes; and 2, dividing power graphics objects of a power device layer in the SVG graphics file into nine categories of a generatrix, a power transformer, a text layer, a connecting line layer, an alarm window, an elliptic arc and other ordinary conduction devices, and converting the power graphics objects into graphics in the G language format according to attributes respectively.

Description

technical field [0001] The invention relates to the technical field of mobile power system automation, in particular to a method for converting substation vector graphics. Background technique [0002] The substation monitoring system under the "big operation" construction system of the State Grid must have a remote browsing function, that is to say, the dispatching master station can browse the screen of the substation and refresh the data in real time. However, the current dispatching and substation graphics systems are heterogeneous, and the graphics file format Incompatibility, it is impossible to realize the seamless connection between dispatching system and substation system graphics. Intelligent dispatching systems generally use G language (graphical programming language) format graphics files, while most substation monitoring systems support SVG (Scalable Vector Graphics, scalable vector Graphics) format graphics files, in order to realize the remote browsing functio...
