Description

Railway signal interlocking drawing automatic checking method and system based on visual interaction Technical Field The invention belongs to the technical field of railway signal drawing verification, and particularly relates to an automatic verification method and system for a railway signal interlocking drawing based on visual interaction. Background The railway signal interlocking system needs to ensure that the logical relationship of track sections, switches and annunciators strictly conform to specifications such as TB/T3027. The traditional railway signal interlocking drawing checking relies on manual comparison design specifications, has the problems of low efficiency, easy omission and the like, and has strong dynamic relevance of interlocking logic particularly in complex station scenes, and hidden troubles such as topology connection errors, signal conflicts, and missing interlocking conditions are difficult to quickly find through manual checking. The related railway signal interlocking drawing automatic check also has the problems that the error positioning is not visual, the correction still depends on a manual mode, and the like. At present, the technical problem is mainly solved by three modes, namely (1) script verification based on rules, scanning the image paper data through predefined rules (such as that the distance between annunciators is more than or equal to 1200 m), and outputting an error list. (2) The semi-automatic checking tool uses a two-dimensional drawing marking tool (such as an AutoCAD plug-in) to mark equipment conflict, and relies on manual judgment of logic rationality. (3) The interlocking table logic verifier is used for importing the interlocking table into a database based on a static checking tool of a preset rule base, detecting contradictory conditions through SQL query, but lacking interactivity, wherein an error prompt is only a text list and visual positioning cannot be realized. However, most of the solutions verify basic rules such as equipment spacing, number uniqueness and the like, and verify for a single data source, errors are displayed in a text form, manual comparison drawing positioning is needed, and part of tools mark the error equipment in CAD drawings by colors, but cannot display logical link relations, and intelligent reasoning capacity ‌ is lacking.
