Method and system for intuitively displaying interlayer relation of graphic element in multi-level model

Abstract

The invention relates to a method for intuitively displaying an interlayer relation of a graphic element in a multi-level model, comprising the following steps of: a, establishing an associative line logic window which at least covers a parent window and a child window and has a transparent background color and a transparent frame; b, acquiring a first positioning point in the parent window, wherein the positioning point where the graphic element is located corresponds to the child window or is associated with the graphic element in the child window; and acquiring a second positioning point on the child window, wherein the positioning point is arranged in the graphic element associated with the first positioning point of the parent window where the graphic element is located in a frame ofthe child window and / or the child window; c, drawing an associative line from the first positioning point to the second positioning point in the associative line logic window; and d, displaying the associative line logic window including the associative line from the first positioning point to the second positioning point. The invention also provides a corresponding system. In the invention, the interlayer relation of the graphic element in the multi-level model is intuitively displayed through drawing the dynamic associative line of a cross-window, and thereby the information screen problem of the traditional multi-window technology during the displaying of the multi-level model is solved.

Description

technical field [0001] The invention relates to a multi-window graphics display technology, more specifically, to a method and system for visually displaying the relationship between graph element layers in a multi-level model. Background technique [0002] With the in-depth development of the application of computer graphics technology, it is an important technology in the graphic information system to represent the spatial structure of the same application object in multiple graphics, that is, to describe the same application object with multi-scale and multi-type graphic data. An important feature of this type of information system is to use a multi-level spatial structure model (also referred to as a multi-level model) to realize the consistent organization and management of multi-scale and multi-type graphic data. [0003] In terms of information display, these systems use "multi-window" display technology to realize the display of multi-scale and multi-type graphic dat...

Problems solved by technology

[0010] if figure 1 Given the substation graphics, the sub-window 12 will have more incoming and outgoing lines, and the cross-layer relationship between parent and child windows will be more complicated. At this time, the traditional "multi-window" technology is more difficult to map important equipment Connections are clearly and accurately displayed

If the electrical connection relationship can only be identified through auxiliary labeling or attribute data query, it will not only bring inconvenience to the application operation, but also cause safety hazards to the production and operation of the power grid due to manual misreading of the internal and external connection relationships of the substation.

[0011] The above problems are only the defects of the traditional "multi-window" technology in graphic display. In addition, because the data modeling work of the multi-level model is very complicated, the establishment of the hierarchical relationship and the cross-layer relationship of the graphic elements is the difficult content of the modeling. It will be more difficult to model inter-layer relationships when faced with complex graphics. At this time, not only will it take a lot of original data modeling time, but also in order to ensure the correctness of the modeling data, the verification cost of the multi-level model association information will also increase sharply.
