Distribution network thematic map annotation self-adaptive layout method

Abstract

The invention discloses a distribution network thematic map annotation self-adaptive layout method, and relates to a layout method. At present, a single-line diagram used by an electric power system has the situation of unreasonable labeling layout, so that the practicability is poor, and few users use the single-line diagram. The method comprises the following steps: obtaining a distribution network thematic map; obtaining annotation requirement information in an annotation module; judging whether the annotation information of the distribution network thematic map meets annotation requirementinformation in an annotation module or not, if yes, ending, and if not, entering the next step; performing annotation modification on the distribution network thematic map according to the annotationrequirement information to complete annotation layout of the distribution network thematic map; and outputting the distribution network thematic map after the labeling layout is completed. Accordingto the technical scheme, self-adaptive layout can be achieved, and the mapping effect is good; the system is simple in structure and flexible in layout, a user can flexibly configure according to ownrequirements, and automatically generate and arrange labels according to user configuration to meet different requirements, so that the application range is enlarged.

Description

technical field [0001] The invention relates to a map layout method, in particular to a self-adaptive layout method for labeling of distribution network thematic maps. Background technique [0002] The distribution network single-line diagram is an important tool for the distribution network dispatching department and the operation inspection department. The single-line diagram is a graph after the system automatically performs an orthogonal layout on the entire feeder topology. [0003] However, due to technical reasons, the one-line diagrams currently used in power systems have unreasonable label layouts, resulting in poor practicability and seldom used by users. Such as figure 1 shown. [0004] 1) The font of the label is too small, and it is not clear after the inspection is printed. The dispatcher needs to enlarge the graphic on the computer to see the label clearly. [0005] 2) The annotation does not provide automatic line wrapping, and long annotations will cover ...

AI Technical Summary

Problems solved by technology

[0004] 1) The label font is too small, and it is not clear after the inspection is printed. The dispatcher needs to enlarge the graphics on the computer to see the label clearly

[0005] 2) The annotation does not provide automatic line break function, and long annotations will cover graphics elements and other annotations

[0006] 3) Labels will overlap, resulting in unclear situations, and the graphics are not beautiful
