TRACK CHECKING METHOD FOR MAGNETICALLY-LEVITATED RAILWAY LINE

摘要

PURPOSE: An inspection method for a track of a magnetic levitation railway line is provided to secure safety in operation of a magnetic levitation train and to prevent various accidents caused by excessive errors in a track by comparing the initial design data of track data with the measured track data, thereby inspecting whether or not the current track is out of order. CONSTITUTION: An inspection method for a track of a magnetic levitation railway line comprises the steps of: fixing a standard reflector(10) having fixed coordinates on the outside of a track; installing many track reflectors(20) to the track at the appointed interval; measuring the coordinates of each track reflector and the distance to the standard reflector by irradiating and receiving light wave to each location of the track reflectors with the standard reflector; installing a track inspection instrument(40) on the track; locating a main reflector(30) to the track inspection instrument and moving along the track, and measuring the distance between the track reflector and the track inspection instrument and the moving coordinates of the track inspection instrument; and receiving the distance between the track reflector and the track inspection instrument, and the moving coordinates of the track inspection instrument with a data processing device installed to the track inspection instrument, and then converting into digital values and storing as track data of the current track.
