Problems solved by technology

[0010] From the above drawing process, it can be seen that in the existing drawing methods, terrain sections, route maps, and pipeline crossings all need to be drawn manually
Especially the drawing of pipeline crossings, the process is cumbersome and error-prone

Embodiment Construction

[0056] Best practice:

[0057] The technical solution of the present invention is based on the operation platform of power grid GIS and CAD drawing. CAD and GIS have a large number of technical overlaps. From the point of view of the purpose of use, CAD is mainly biased towards drawing and expression, while GIS is more focused on solving spatial problems. Therefore, CAD has a strong graphic editing function, and has strong typesetting and drawing capabilities, and the core function of GIS is spatial analysis.

[0058] Refer to attached figure 1 , the method for automatic generation of underground cable and pipeline plane section diagrams, including the following steps: (1) preprocessing of pipeline point data; (2) drawing of pipeline point plane diagrams combined with GIS; (3) formation of pipeline plane diagrams; (4) extraction of pipelines The plan data is automatically drawn into a pipeline plan view.

[0059] The first is the preprocessing of pipeline point data:

Abstract

The invention relates to a drawing generating method, in particular to a method for automatically generating a plane-section drawing of underground cable duct lines. The method for automatically generating the plane-section drawing of the underground cable duct lines is characterized by comprising the following steps of (1) preprocessing duct line point data, (2) drawing a plane drawing of duct line points through a GIS, (3) forming a plane drawing of the duct lines, and (4) extracting duct line plane drawing data to automatically draw the plane-section drawing of the duct lines. The method for automatically generating the plane-section drawing of the underground cables duct lines has the advantages that duct line crossing data are automatically extracted from the plane drawing of the duct lines, so that manual calculation is avoided; a path diagram and terrain section data are automatically extracted from the plane drawing of the duct lines, so that repeated manual drawing of the plane-section drawing is avoided; automatically extracted line paths, duct line crossing, terrain sections, path diagram data are introduced so that the duct line plane-section drawing can be automatically drawn efficiently and rapidly, and the automation degree is high; the types of the duct lines and the type of the duct line points are automatically judged according to the duct line codes and duct line point codes, and duct line point objects are drawn in batches; the drawing forming efficiency is high, the process is simple, and drawing workload is greatly lightened.

Description

technical field [0001] The invention relates to a method for generating graphics, in particular to a method for automatically generating planar sections of underground cables and pipelines. Background technique [0002] Explanation of basic terms: [0003] Line coordinate system: An engineering coordinate system with the center line of the line as the horizontal axis and the vertical center line as the vertical axis. It expresses the coordinates of ground objects in terms of accumulative distance and offset distance relative to the center line of the line. Usually, the backsight direction is also called the small direction, and the frontsight direction is also called the large direction. [0004] Horizontal section diagram: a line engineering drawing that takes the center line of the line as the horizontal axis and combines the plan view and the section view. The plan part adopts the line coordinate system, and all the coordinates of the topography and objects are relative ...
