Automatic outputting method of electric transmission line house distribution map

Abstract

The invention discloses an automatic outputting method of an electric transmission line house distribution map. The automatic outputting method comprises the steps of: performing secondary development by applying VB (Visual Basic) and Lisp (List Processor) in an AutoCAD (Auto Computer Aided Design) environment; realizing automatic clipping in batches by aiming at house information in a planar graph and a sectional drawing of an engineering line of the electric transmission line; automatically extracting to identify and mark an accumulated line distance of each start point and each end point of each house distribution map; automatically editing page number and the like of the distribution map; and finally automatically superposing and standardizing frame of the map to form collective drawings of the house distribution map. The automatic outputting method of the electric transmission line house distribution map, disclosed by the invention, has the advantages of efficiently avoiding occurrence of error condition of manual filling of page number and start-stop distance of the house distribution map and mass amending work caused by change of the planar graph and the sectional drawing and the house information, reducing work intensity of the map edition efficiently and realizing automatic outputting of the house distribution map.

Description

technical field [0001] The invention relates to an automatic mapping method for building distribution diagrams of power transmission lines, and belongs to the technical field of engineering surveying in the discipline of surveying and mapping. Background technique [0002] Usually, in the survey and design of 500kV and above transmission line projects, it is necessary to measure the houses and other buildings on both sides of the center line of the line, and then compile the house distribution map according to the measurement results, as an important basic data for technical and economic statistics. [0003] The national standard of the People's Republic of China "Specifications for Surveying 330kV~750kV Overhead Transmission Lines" (GB 50548—2010) regulates the surveying and mapping requirements in this area, and Chapter 6.10.4 of the regulations introduces the requirements for the compilation of building distribution maps. Usually, each picture should include the accumulat...

Problems solved by technology

The shortcomings of this manual editing method mainly include: the page number and mileage filling of the housing distribution atlas are prone to errors; once the information in the planar section is adjusted, the housing distribution needs to be modified, which increases the work of atlas compilation Intensity; especially for long-distance transmission line projects in economically developed areas, there are many houses involved, and there are hundreds of distribution maps. If manual editing is used, the workload will be very large, and it is easy to make mistakes and cause rework
