Abstract

The invention discloses a coordinate measurement system for track lines. The coordinate measurement system comprises a total station, a track inspection car and a processing unit. The total station erected on a track line is used for measuring three-dimensional coordinates of CP III points. The track inspection car running on the rack line is used for measuring line shapes between two corresponding line marking points of the two CP III points on the track line, and measuring horizontal distance and height difference values between the two line marking points and the two corresponding CP III points. According to the three dimensional coordinates of the two CP III points, geometrical relationships between the horizontal distance and height difference values between the two CP III points andthe corresponding line marking points thereof on the track line, and the line shapes between the corresponding line marking points of the CP III points on the track line, the processing unit solves three-dimensional coordinates of the corresponding line marking points of the CP III points on the track line by importing measurement data of the total station and the track inspection car. By the coordinate measurement system, the technical problems of labor and time consumption and low measurement accuracy of existing track line coordinate measurement methods can be solved.

Description

technical field [0001] The invention relates to the field of railway engineering measurement, in particular to a measurement system from CPⅢ coordinates to track line coordinates. Background technique [0002] At present, the network construction measurement methods of railway engineering mainly include CPⅢ line coordinate measurement and track alignment measurement. as attached figure 1 As shown, the total station (for measuring line coordinates and CPⅢ point coordinates) 1 is erected on the line during measurement, and prisms are inserted at 3 pairs of CPⅢ points before and after the total station 1, and each station is set up to measure 6 pairs in total. 12 points. The measurement method adopts the free station corner intersection method of the total station, and the total station 1 is erected in the middle of the three pairs of CPⅢ points 20 at the front and rear respectively, so as to ensure that the distance between the free stations is not more than 300 meters.
