An automatic detection method for platform invasion of a curve section

Abstract

The invention belongs to the technical field of metro boundaries, and particularly relates to an automatic detection method for platform invasion of a curve section, which specifically comprises the following steps of S1 establishing a reference coordinate system, and obtaining coordinates of points on the center line of a whole line on the coordinate system; S2 identifying the circular curve, theeasement curve and the straight line contained in the line segment; S3 widening calculation is conducted on points on different curve types, and a building limit is obtained through drawing; and S4 respectively obtaining distances and directions of corresponding points on the building boundary and the platform contour edge line, comparing the distances and directions with standard values requiredby the boundary, judging whether the platform invades the boundary or not, and finishing automatic invasion detection. The method can effectively solve the problems that an existing checking method is large in workload, long in consumed time and incapable of reflecting a limit checking result simply, conveniently and visually, can greatly improve the invasion detection efficiency and the operation safety, has the advantages of being visual in result, simple in algorithm and the like, and is particularly suitable for automatic detection of invasion of a curve section platform of a subway platform.

Description

technical field [0001] The invention belongs to the technical field of subway boundaries, and more particularly relates to an automatic detection method for platform violations in curved sections. Background technique [0002] Gauge checking is a key step to ensure the safety of subway vehicle operation. If the problem of limit violation cannot be found in time during the design stage, it will cause rework of civil engineering or cause operational safety accidents. [0003] At present, the limit check basically relies on manual drawing measurement, and the limit check personnel need to have rich experience in limit design. The boundary check of the curved platform section of the underground station is more complicated than other sections. If the distance between the curved platform section and the center line of the line is too large, the gap between the platform and the vehicle will be too large after parking, and accidents of stepping on the air will easily occur, which wi...
