Embodiment Construction

[0040] Utilize the method of the present invention to carry out survey and design work respectively in mountainous area line (Khanhai-Guyuan-Ping'an City line Hebei section) and plain line (500KV Shijiazhuang City Shibei-Shidong line), concrete method step is according to above-mentioned content of the invention The technical scheme in the section is operated.

[0041] What needs to be explained here is the problem of converting GPS measurement data into Daoheng ORG format:

[0042] Develop corresponding software (namely, data batch processing interface software) that can quickly convert a large amount of data output by the appropriate software into the required data format (*.TL and *.CSV).

[0043] (1) Choice of development language:

[0044] Because this software does not need too many interfaces, it only needs to input the original file name and generate the specified file. Therefore, instead of choosing the visual language, C language is chosen as the development languag...

Abstract

The present invention relates to a method for integrating the survey and design of power transmission lines with internal and external work using all-digital photogrammetry technology. The present invention is improved on the basis of the prior art. Plane section data, after field measurement and adjustment, use the data batch processing software interface to input the plane section data into the Daoheng software platform. The invention has the beneficial effects of low cost, high work efficiency, reduced labor intensity, less personnel investment, reliable quality, easy popularization and application, and remarkable economic and social benefits.

Description

technical field [0001] The invention relates to a method for integrating internal and external industries in the survey and design of a power transmission line by using a fully digital photogrammetry technology, and belongs to the technical field of survey and design methods for a power transmission line. Background technique [0002] With the development of computer technology and aerial survey technology, in the late 1990s, the aerial photogrammetry industry developed from the stage of simulation and analysis to the stage of fully digital photogrammetry realized on the computer. The aerial survey work is automatically completed in batches on the computer, which significantly reduces the quality of the aerial photos and the technical requirements of the operators; the automatic aerial triangulation greatly reduces the number of image control points in the field; the development and application of GPS technology makes the field The measurement work ...
