Method and system for drawing vector diagram of overhead line

Abstract

The embodiment of the invention provides a method and a system for drawing a vector diagram of an overhead line. The method comprises the following steps of: determining a start point coordinate and a quasi end point coordinate, and calculating a distance between a start point and a quasi end point according to the start point coordinate and the quasi end point coordinate; presetting a span between every two supporting points; along a direction from the start point to the quasi end point, building a supporting point at a distance equal to the span; taking the supporting point closest to the quasi end point as an actual end point until a distance from the supporting point closest to the quasi end point to the quasi end point is smaller than a second threshold value; and connecting the start point and the supporting point adjacent to the start point through a line segment, connecting any two adjacent supporting points through another line segment, and connecting the actual end point and the supporting point adjacent to the actual end point through a third line segment.

Description

technical field [0001] The invention relates to the technical field of overhead line drawing, in particular to a method and system for drawing a vector diagram of an overhead line. Background technique [0002] A vector diagram, also known as an object-oriented image or a drawing image, is defined mathematically as a series of points connected by lines. Graphical elements in vector files are called objects. Each object is a self-contained entity with attributes such as color, shape, outline, size, and screen position. An overhead line vector diagram, on the other hand, represents an image of an overhead line using a series of points connected by lines. [0003] The overhead line vector diagram mainly includes support points and line segments connecting the support points. The support points represent facilities such as poles or electric meters in the overhead line vector diagram, and the line segments represent soft wires. In addition, the first supporting point at the st...

Problems solved by technology

However, the existing overhead line vector diagram must be manually drawn one by one according to the actual position of each support point, the distance and angle between each support point and other factors during the drawing process, and manually connect each support point with a line segment one by one, so The drawing efficiency is low, and the quality is also affected by human factors

[0005] In addition, there is no relationship between the support points and the connection lines of the overhead line vector diagram drawn by the existing drawing tools, and they are independent of each other. Therefore, when a certain support point moves, the connection line connected to the support point It cannot follow the support point and must be artificially modified, which increases the workload for the staff who draw the vector map
