Method for converting topographic map data format to overhead line format

Abstract

The invention provides a method for converting a topographic map data format to an overhead line format and belongs to the technical field of design tower emptying of a power line. The method comprises the following steps of: 1, reading a file of the topographic map data format, and importing contents of the file into a topographic map database table; 2, reading distance of a distance center line; 3, reading a starting point number; 4, converting the topographic map database table to a database table which corresponds to the file of the overhead line format according to the distance of the distance center line and the starting point number; and 5, converting the database table which corresponds to the overhead line format to the file of the overhead line format. By the method, the technical problems of complicated process, time consumption, labor consumption, high error rate and the like of the conventional conversion method are solved.

Description

technical field [0001] The invention belongs to the technical field of power line design and arranging towers, and in particular relates to a method for converting a topographic map data format into an overhead line format. Background technique [0002] With the development of science and technology in our country and the needs of engineering technology, there are more and more large-scale topographic maps. We can skillfully use the existing vectorized large-scale topographic maps to provide high-quality and fast services for our engineering construction. Vectorized Large Scale Terrain Figure 1 Generally, they are saved in DWG and DXF formats of AutoCAD, and can be opened by the commonly used measurement software Southern CASS Mapping System. In fact, the Southern CASS Mapping System can also generate cross-sectional drawings, but it can only generate its own format in AutoCAD and cannot be used for Design row towers for power lines. [0003] Therefore, according to the co...

Problems solved by technology

[0005] These conventional methods are cumbersome, time-consuming, and labor-intensive, and are prone to errors. If the overhead power transmission line is short, fortunately, if the overhead power transmission line is long, sometimes it cannot meet the requirements of the construction period.
