Abstract
The invention discloses an electric transmission line three-dimensional design method based on a Google Earth and an electric transmission line three-dimensional design system based on a Google Earth. The method comprises the following steps: designing initialization, thereby determining parameters of a to-be-designed electric transmission line; performing wire selection design on the Google earth according to the preset data organization mode and the parameters of the to-be-designed electric transmission line, thereby obtaining a selected path graph and selected corner coordinates; performing electric transmission line ground object vectorization marking and profile point data acquisition treatment on the Google earth according to the selected corner coordinates; generating a flat profile graph; performing pole tower position primary exclusion according to the generated flat profile graph; generating a parametrization three-dimensional iron tower modeling module, and loading the parametrization three-dimensional iron tower modeling module in the Google earth and performing three-dimensional roaming and design optimization, thereby obtaining a tower position outcome table; outputting the generated path graph, flat profile graph and tower position outcome table. The electric transmission line three-dimensional design method has the advantages of convenience and rapidness in data acquisition and low cost, and can be widely applied to the technical field of power engineering.
Description
technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a Google Earth-based three-dimensional design method and system for transmission lines. Background technique [0002] Glossary: [0003] Ruby language: an object-oriented, imperative, functional, and dynamic general-purpose programming language, designed and developed by Japanese Matsumoto Yukihiro in the mid-1990s. [0004] Google SketchUp software: Google SketchUp software is a free 3D design software provided by Google. [0005] Power line selection should comprehensively consider natural and geographical conditions as well as economic and social factors. Therefore, a topographic map with high reality is required as the basis. The acquisition cycle of topographic map data is long and the cost is high. [0006] When designing traditional transmission lines, designers need to conduct site selection, line selection and project demonstration on the basis of to...
