A Judgment Method for Vertical Section in Non-contact Measurement of Railway Platform Gauge

Abstract

The invention discloses a method for judging the vertical section in the non-contact measurement of the railway platform limit, which includes the measurement of the straight line section and the measurement of the curved section, wherein the measurement of the straight line section includes the following steps: step S110, determining the measurement point, taking the rail closest to the platform as the For reference, take any point on the other side of the rail as the measurement point A; step S120, select a comparison point, take the measurement point A as the origin, measure the distance AE between the two in comparison with any point E on the rail, and on both sides of the point E Select comparison point B and point C respectively on the railroad track; Step S130, data measurement; Step S140, data calculation; Curve segment measurement comprises the following steps: Step S210, determine measurement point; Step S220, select comparison point; Step S230, data calculation . The beneficial effect is that: non-contact measurement is adopted, the measurement time is not limited, the position of the vertical section can be measured and determined in real time, and there is no need to go on the road, and the safety is good; there are few measurement points, the measurement operation is simple, and the data is reliable.

Description

A method for judging vertical sections in non-contact measurement of railway platform boundaries technical field The present invention relates to railway platform limit maintenance technical field, be specifically related to a kind of railway platform limit non-contact measurement The method for determining the mid-vertical section. Background technique [0002] The railway station platform is an important facility for trains to stop and passengers to get on and off. Different degrees of settlement and displacement occur, resulting in different degrees of deformation of the platform, thereby changing the relative relationship between the platform and the line. Location, platform limit exceeding the limit may affect the opening and closing of the train doors, and the car body may be scratched when the limit is seriously exceeded and other safety incidents. Therefore, the railway housing construction department needs to implement dynamic management of the limits of the ...
