Detecting System of Track Static Regularities Based on the Laser Tracker

Abstract:

With the rapid development of highspeed railway and urban rail transit, the significance of security is of unprecedented significance. Track regularity is of crucial importance to highspeed railway operation safety. This paper proposed a method to detect track static regularities based on a laser tracker. A track static regularity detecting system was built based on the laser tracker integrated displacement sensor, tilt sensor and communication sensors and their platform setup. Software development was aimed at verifying the methods of track static regularity detecting and data processing. In order to verify the detecting and data processing method of track static regularity, experiments were conducted at a part of the Shanghai metro line 13 at Natural Museum Station. The SGJTCECⅠpassenger dedicated line track geometric condition detection device was used for comparative analysis. The feasibility and high accuracy of the track static regularity detecting method and data processing method are verified by using the SGJTCECⅠpassenger dedicated line track geometric condition detection device.
