Abstract

The present invention provides a track deviation measurement reference setting method, device and system. The method includes the following steps that: a first reference point for track deviation measurement is set at a first position, and a second reference point for track deviation measurement is set at a second position; the first reference point and the second reference point respectively maintain determined position corresponding relations with a traveling track, and / or track surface control points are adopted to determine the position coordinates of the first reference point and the second reference point; and a first laser beam is transmitted to the second reference point through the first reference point, the first laser beam serves as a first reference line for track deviation measurement, and part of light energy is separated out from the first laser beam by an optocoupler on the light path of the first laser beam so as to be used for track deviation measurement. The method,device and system have the advantages of low cost, high efficiency, small error and high practicality.

Description

technical field [0001] The invention relates to the field of automatic measurement, in particular to a method, device and system for setting a benchmark for orbital offset measurement. Background technique [0002] With the expansion of rail transit construction and operation scale, how to improve the efficiency and accuracy of track smoothness detection has become a concern of the industry. [0003] The inspection items for the new track and the operating track include: the height difference between the two running rails, the distance between the running rails, and the curvature of the track. These test items also come down to the gauge smoothness, direction smoothness, vertical smoothness and height smoothness detection between two tracks. Each of these four smoothness can further include smooth short-wave characteristics, medium-wave characteristics and long-wave characteristics. characteristic. [0004] Usually, the four-term smoothness between the above two tracks is ...
