Abstract

The invention discloses a method and system for constructing a railway hub digital network model. The method comprises the following steps of S1, extracting the endpoint coordinates of a straight lineobject, an arc object and a multi-segment line object in a vector graph file containing the railway graph information; S2, determining a multi-segment line object meeting the condition of forming thestation as a station object; S3, checking the end point coordinates of multiple segments of line objects of the straight line object, the arc object and the non-station object, connecting two objectswith the same end point coordinates, and generating a line object; S4, traversing the end point coordinates of the station object and the line object to obtain an intersection point of the station object and the line object, connecting a center point and the intersection point of the station object, and establishing the physical connection of the station object and the line object; S5, marking the station object and the driving direction on the line object according to the line type of the line object. According to the method, the convenience and the accuracy of reading and identifying the railway hub information in the vector graph are improved, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of railway systems, and more specifically relates to a method and system for constructing a digital network model of a railway hub. Background technique [0002] When analyzing large-scale railway hub lines and station capabilities through computers, it is necessary to logically abstract and digitize the real railway hub lines, station structures and locations to obtain a railway hub network model; at present, it is mainly through manual input of railway hubs Information is used to build a digital network model of railway hubs. Due to the large amount of information contained in railway hub information, manual operation is not only inefficient but also error-prone. [0003] Vector graphics use straight lines and curves to describe graphics according to geometric characteristics. The elements of vector graphics are points, lines, rectangles, polygons, circles and arcs, etc., which are all calculated by mathem...
