Construction Method of Plane Design Diagram of Overhead Rigid Catenary of Subway

Abstract

The invention relates to a method for constructing a plane design diagram of a subway overhead rigid catenary. The graphic design of the overhead rigid catenary of the subway involves many professional interfaces, a long process, and a large workload of modification and proofreading. The invention loads basic data, adopts an interactive method to preprocess drawings; adopts an intelligent anchor section division algorithm to divide anchor sections for interactive adjustment; adopts an intelligent suspension point layout algorithm to arrange suspension points, detect suspension point conflicts and adjust spans; The standard design method of the crossing line is used to design the crossing line; the pull-out value automatic calculation algorithm is used to calculate and mark the pull-out value; the bus bar layout algorithm is used to arrange the bus bar; according to the set installation drawing number marking rules, the overhead rigid catenary installation is automatically extracted and marked Drawing numbers and other design elements; counting engineering quantities and performing drawing, cutting and splicing. The invention provides a standardized method for plane design of the overhead rigid catenary of the subway, and meets the short-term, high-quality, and efficient drawing requirements of the catenary professional of the subway.

Description

technical field [0001] The invention belongs to the technical field of electrified railway catenary, and in particular relates to a method for constructing a plane design diagram of a subway overhead rigid catenary. Background technique [0002] With the development of my country's urban rail transit, subway construction has entered a period of rapid development. The graphic design of overhead rigid catenary for subway is the main work content of catenary major, which involves many professional interfaces, long design process, and heavy workload of revision and proofreading. Traditional design methods require designers to repeatedly confirm various design interfaces, manually process redundant graphic elements in the input map, manually divide anchor sections of stations and intervals, and arrange suspension points. At the same time, it is necessary to consider various pipeline equipment on the drawing Whether there is a conflict and repeated adjustments, various pull-out v...

Problems solved by technology

Traditional design methods require designers to repeatedly confirm various design interfaces, manually process redundant graphic elements in the input map, manually divide anchor sections of stations and intervals, and arrange suspension points. At the same time, it is necessary to consider various pipeline equipment on the drawing Whether there is a conflict and repeated adjustments, calculate various pull-out values ​​in the form of a table, and finally need to perform tedious work such as filling in the installation drawing number and counting the number of projects

The entire design process was lengthy and time-consuming, making it the main controlling factor in the metro catenary design work
