Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] The main tasks of the method of the invention include: defining the rules for drawing icons; extending the function of the general open source software Qtsvg library; classifying and associating measurement data with graphic element svg texts, and generating and analyzing dynamic svg texts. A detailed description will be given below.

[0023] Rules for defining SVG primitives:

[0024] 1.svg file header

[0025] Create an empty file containing the svg file header (generally common svg editors can be created), the file header mainly includes parameters:

[0026] Xmlversion;

[0027] Character encoding: use utf-8 encoding;

[0028] DOCTYPE: svg and version;

[0029] The root element at the beginning of Svg, including information such as the width, height and name space of the scene;

[0030] 2. defs

[0031] The icon symbol definition is placed in...

Abstract

The invention relates to an SVG standard customizable graphic symbol based power system graphic display method. A power system image is displayed through an SVG graphic element, wherein the SVG element comprises the following attributes: an SVG file header; defs, used for storing a graphic symbol definition; a graphic symbol, used for describing a display mode of a power system object image; graphic element conversion, comprising translation, scaling and rotation; a layer number, used for reflecting a sequence of adding graphic elements into a scene, wherein a currently loaded graphic element covers a previously loaded graphic element; and a group number, used for grouping the graphic elements. According to the method, a power graphic symbol can be flexibly drawn, so that the workload and cost of independent development are reduced, the development efficiency is improved, and the development cycle is shortened.

Description

technical field [0001] The invention relates to a power system graphic display method based on SVG standard and customizable icons. Background technique [0002] SVG (ScalableVectorGraphics) is a two-dimensional graphics description language based on XML language released by W3C organization. It is used to describe two-dimensional vector and vector / raster graphics. It has powerful dynamic interaction characteristics, uses text transmission, and is small in size and fast in speed. , there are many open source SVG graphics editors for viewing and editing, and many browsers support viewing. The text in SVG can be used by search engines, but the text written in bitmap images cannot. [0003] As an industry standard for network vector graphic files, SVG provides a new technical means for the graphic display of power systems. Its openness, platform independence and network publishing characteristics fully meet the drawing requirements of power system primary wiring diagrams. [0...
