Embodiment Construction

[0060] The concrete implementation steps of the present invention are described in detail below in conjunction with accompanying drawing:

[0061] A method for loading an ultra-large-scale graphic file of a distribution network, comprising the following steps:

[0062] Step 1. Divide the graphics file into an index area, a basic area, and a sub-screen area. The sub-screen area contains multiple sub-screens. The graphic elements occupying 1 sub-screen are saved in the sub-screen, and the graphic elements that span sub-screens are saved in the basic area. area, the index area includes the starting position offset of the basic area in the graphic file and the starting position offset of each sub-screen represented by id in the graphic file;

[0063] Such as figure 2 Shown:

[0064] S1, start saving the primitive in the graphics file;

[0065]S2. According to the size of the graphics canvas, the width and height of the sub-screens, calculate the number of rows r, the number of...

Abstract

The invention relates to a method for loading super-large-scale graphic files of a power distribution network. The method comprises the steps of firstly classifying the graphic files into an index region, a basic region and a sub-screen region, wherein the sub-screen region comprises a plurality of sub-screens, graphic elements with sub-screen occupation numbers of 1 are stored in the sub-screen, and graphic elements across the sub-screens are stored in the basic region; and secondly loading the graphic elements in the basic region and the graphic elements in the sub-screens in sequence, and performing graphic zoom display. According to the method, the problem of low super-large-scale graph opening and roaming efficiency of the power distribution network is solved; and compared with the prior art, the method has the advantages that which graphic elements are loaded is decided only according to a current viewport, so that the graph opening and roaming speed can be effectively increased.

Description

technical field [0001] The invention relates to the field of distribution dispatching automation, in particular to a method for loading a super-large-scale graphic file of a distribution network. Background technique [0002] The number of graphics elements and the size of graphics in distribution network graphics are generally large. When encountering super-large graphics, multiple sub-screens are required to cooperate with the display. The traditional graphic loading method is used to fully load the entire graphic, resulting in a long time to open the graphic. However, when using the general screen slicing method, in order to display a bus or feeder section, multiple sub-screens need to be loaded at the same time, resulting in a great waste of resources and prolonging the graphics loading time. Contents of the invention [0003] Aiming at the above-mentioned problems existing in the prior art, the present invention discloses a method for loading super-large-scale graphi...
