Problems solved by technology
This method can realize automatic modeling of power lines, but this method needs to generate drape equations according to specific situations. Different drape equations need to be established in different virtual geographic scenes, which has poor flexibility, and the degree of line simulation is not high. Calibration is cumbersome

The invention provides a power line modeling method based on a three-dimensional geographic information system, which comprises the following steps: in the geographic information system, determining astarting point connecting piece and an end point connecting piece of a connecting wire between a target tower and a tower, and determining a starting point coordinate and an end point coordinate of wire connection and normal vector information of the connecting wire according to DEM data; calculating the wire outlet direction of wire connection; determining a midpoint of a starting point and ending point connecting line; and constructing a split conductor entity model according to the conductor center line, and then modeling the power line. Through an innovative calculation and simulation method and based on a three-dimensional geographic information system platform, the problems of design, simulation and display of split conductors and spacer models of the split conductors in power linedesign are solved, engineering is optimally designed, and the models can be more accurate.
Description
technical field [0001] The invention relates to the field of three-dimensional geographic information system modeling, in particular to a modeling method and system for power lines based on a three-dimensional geographic information system. Background technique [0002] With the advancement of the intelligent construction of the State Grid, the results of digital 3D power lines have become particularly important. At present, there are multiple software platforms in China that can perform 3D design of power lines, but the quality of the design results is not high. [0003] The 3D geographic information system is based on the traditional geographic information system technology, with the virtual reality of the real 3D scene, which has the characteristics of intuition, reality, visibility and efficiency, and has been widely used in digital cities and other fields. At the same time, with the continuous expansion of the grid scale, the power equipment data and other information t...
