TRACK IRREGULARITY MEASURING METHOD AND ITS MEASURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a track irregularity measuring method and its measuring device capable of continuously, quickly and accurately measuring necessary track irregularity information by remote monitoring from a monitoring center without running an inspection car by laying optical fiber cable sensors on a rail. SOLUTION: The optical fiber cable sensors 11 are applied to a web of the rail 5A along the railroad rail 5A, and an irregularity of a laying position of the rail 5A is detected by comparing pieces of information from the optical fiber cable sensors 11 with a laying reference information storage 24 of the rail.
