WATER SURFACE FLOATING TYPE RF TAG
To provide a water surface floating type reliable RF tag which keeps itself in a sealed state, is held at a prescribed location, maintains its attitude without receiving effects of peripheral water level variations, secures a good condition to communicate with a reader/writer and detects firmly the location of a train traveling on a track without omission.SOLUTION: A water surface floating type RF tag 10 installed in rail track 11 side to communicate to a reader/writer attached to a bottom of a train traveling on the rail track 11, comprises a hollow vessel 15 possessing a sealed space 14 inside and a RF tag 17 attached to an upper side of the sealed space 14, moves vertically according to a variation of the water level when the rail track 11 submerges and makes an upper surface 16 side of the vessel 15 exposed above the water 22.SELECTED DRAWING: Figure 4
【課題】ＲＦタグを密閉して所定の位置に保持し、周囲の水位の変化に影響を受けることなくＲＦタグの姿勢を維持して、リーダライタとの良好な通信状態を確保し、軌道上を通過する列車の位置を漏れなく確実に検出することができる信頼性に優れた水面浮上型ＲＦタグを提供する。【解決手段】軌道１１上を移動する列車の底部に取り付けられるリーダライタと通信を行うために軌道１１側に設置される水面浮上型ＲＦタグ１０であって、内部に密閉空間１４を有する中空状の容器１５と、密閉空間１４の上側に取り付けられるＲＦタグ１７とを有し、軌道１１の冠水時に、水位の変化に伴って上下動し、容器１５の上面１６側を水２２上に露出させる。【選択図】図４
