TRACK RAIL MAINTENANCE SYSTEM AND TRACK RAIL MAINTENANCE METHOD

摘要

A track rail maintenance system performs maintenance work, and accurately grasps a shape of a track rail and positions of structures, using position data of a maintenance vehicle detected by a GPS. The maintenance vehicle includes positioning data acquiring means 412 for decoding the positioning signals to acquire positioning data, position data acquiring means 411 for acquiring position data of the maintenance vehicle on the basis of rotation of a predetermined axle attached to the maintenance vehicle, and comparing and judging means 413 for comparing the positioning data and the position data at a start point of maintenance work set on the basis of a track shape/structure database and judging whether a difference between the positioning data and the position data is within a predetermined range. The maintenance vehicle corrects the position data when the difference between the positioning data and the position data is not within the predetermined range as a result of the comparing and judging means 413.
