<p>The present invention relates to a system for measuring the position of tag location of train rail. More particularly, the present invention relates to a train rail position measuring system (10) including a vehicle (11) having wheels (19, 21) for driving and braking and a separate pair of wheels (23, 24) not for driving and braking. The train rail position measuring system (10) comprises: a GPS receiving unit (15) for receiving GPS location information wirelessly from the outside; a pair of odometers (17, 18) for outputting the information about moving distance according to the number of rotations of the wheels, installed at each of the wheels (23, 24); and a control terminal (13) for receiving location measurement values from the GPS receiving unit (15) and the pair of odometers (17, 18) and for processing the received location measurement values by a certain algorithm to determine a specific location on the trail rail. The present invention selectively uses the GPS location measurement values and location measurement values of the pair of odometers, thereby accurately measuring the location value at a certain location on the trail rail at various environments. Therefore, a single measurement can acquire an accurate location value.</p> |
