A system and method for line selection, ranking interaction, and scene modeling of multiple branches

Abstract

The invention discloses a multi-circuit branch line selection, ranking interaction, and scene modeling system and method. The multi-circuit branch line selection module determines the grid logic relationship of the power transmission system and generates a circuit plane section index. Sectional path section diagram and re-write the segmented plane section database; the tower positioning module uses the loop plane section index and reuses the segmented plane section database to arrange the towers of the loop path; and the 3D scene modeling module uses the hanging line template , automatically arrange the most hanging ground wire hanging mode, and carry out the three-dimensional scene modeling of the power transmission system. It can realize the whole-process processing and processing of line selection, ranking interaction, and scene modeling of complex line types such as single-circuit and double-circuit conversion, line breaking, and mixed-voltage line branching, to meet the design requirements of complex transmission grid engineering, thereby improving transmission engineering. The integration and practicability of the 3D collaborative design system maintain the consistency of the design results, the high degree of information sharing, and greatly improve work efficiency.

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...

AI Technical Summary

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
