Multiple-loop branch line selection, ranking interaction, scene modeling system and method

Abstract

The invention discloses a multiple-loop branch line selection, ranking interaction, scene modeling system and method. The multiple-loop branch line selection, ranking interaction, scene modeling system and method comprises the steps of sequentially determining net rack logical relation of a power transmission system through a multiple-loop branch line selection module and generating a loop flat cross section index, cutting a segmented path cross section diagram and re-writing the segmented path cross section diagram into a segmented flat cross section database, enabling an in-line tower positioning module to utilize the loop flat cross section index and reuse the segmented flat cross section database to perform loop path rod tower ranking, enabling a three-dimensional scene modeling module to utilize a line-hanging template to automatically arrange a best ground wire hanging mode and perform three-dimensional scene modeling of the power transmission system. The multiple-loop branch line selection, ranking interaction, scene modeling system and method can achieve whole-process processing including single-loop and double-loop transformation, line connection and disconnection, selection of mixed-compression line branches and other complicated circuit types, ranking interaction and scene modeling and meets the design demand of a complicated power transmission net frame project, accordingly the integrity and practicability of a three-dimensional collaborative design system of the power transmission net frame project are improved, front-back consistency of a design result is kept, information sharing degree is high, and working efficacy is remarkably improved.

Description

technical field [0001] The invention relates to a GIS and CAD-based system and method capable of realizing multi-circuit line selection, ranking interaction and scene modeling, belonging to the field of power transmission engineering design. Background technique [0002] With the development of computer technology and the deepening of transmission engineering integration software development, the design method of transmission engineering has gradually changed from traditional to three-dimensional collaborative fine design, which has greatly improved the efficiency and quality of transmission engineering design. [0003] However, the 3D collaborative design of power transmission projects started relatively late compared to other fields. The current integrated software can only barely handle the line selection and pole tower arrangement of point-to-point simple paths; It is difficult to meet the design requirements of conventional power transmission projects for common and com...

Problems solved by technology

[0005] 1. The line selection system only supports point-to-point path selection in one direction, which is expressed as a collection of illogical segmented paths, which cannot correctly describe the grid relationship of the transmission grid system

[0006] 2. On the basis of the illogical segmented path collection, each segmented path can only be ranked in isolation, which not only cuts off the control voltage and the consistency relationship between the front and rear overlapping towers, but also only passes through the The manual mode is repeatedly judged and modified, the operation process is primitive and error-prone, and the work efficiency needs to be improved

[0007] 3. Due to the lack of correlation between the segmented path and the ranking towers, the 3D scene modeling can only be manually filtered, overlapped, and mixed-pressure multi-circuit towers. Such operations are overly dependent on The manpower mode directly leads to high work intensity and directly affects the work efficiency and correctness of the design
