To provide a method, by which a speed of a railway vehicle is measured using a plurality of RFID tags installed in a railway vehicle while a facility in a track side is suppressed to be at a low cost.SOLUTION: A speed measurement system 30 of a railway vehicle comprises a plurality of RFID tags 34 dispersedly installed in a railway vehicle 20 in two or more different locations along a front and rear direction of the railway vehicle 20, an RFID reader 40 installed in a side of a track 18 on which the railway vehicle 20 runs and reading tag information from the RFID tags 34 and a speed calculation unit to calculate the speed of the railway vehicle 20 based on time differences which the RFID reader 40 has read from the respective tag information of the RFID tags 34 and distances between the RFID tags 34 in the railway vehicle 20.SELECTED DRAWING: Figure 1

    【課題】目的は、鉄道車両に設けられた複数のRFIDタグを利用し、軌道側の設備コストを低く抑えつつ鉄道車両の速度を測定できるようにすることである。【解決手段】鉄道車両の速度測定システム30は、鉄道車両20の前後方向に沿って異なる2以上の位置に分散するように鉄道車両20に設けられた複数のRFIDタグ34と、前記鉄道車両20が走行する軌道18側に設けられ、前記複数のRFIDタグ34からのタグ情報を読取るRFIDリーダ40と、前記RFIDリーダ40が前記複数のRFIDタグ34のそれぞれの前記タグ情報を読取った時間の差と、前記鉄道車両20における前記複数のRFIDタグ34間の距離とに基づいて、前記鉄道車両20の速度を演算する速度演算部と、を備える。【選択図】図1
