THREE-DIMENSIONAL GIRDER DISPLACEMENT SENSOR MODULE FOR BRIDGE, THREE-DIMENSIONAL GIRDER DISPLACEMENT DETECTION SYSTEM FOR BRIDGE, AND THREE-DIMENSIONAL GIRDER DISPLACEMENT DETECTION METHOD FOR BRIDGE

To quickly know the propriety of the passage on a bridge.SOLUTION: A three-dimensional girder displacement detection system 100 for bridges includes a three-dimensional girder displacement sensor module 101 for bridges and a server device 102. A three-dimensional girder displacement sensor module 101 for bridges measures the displacement of a bridge girder provided in association with a plurality of antennas 104_A and 104_B for receiving radio waves for position detection, based on output signals from the plurality of antennas 104_A and 104_B, and wirelessly transmits measurement information including the measured result by radio. The server device 102 determines the possibility of passage of the bridge BR based on the measurement information, and outputs the result of the determination.SELECTED DRAWING: Figure 1 【課題】橋梁の通行の可否を速やかに知ることを可能にする。【解決手段】橋梁用三次元桁変位検知システム１００は、橋梁用三次元桁変位センサモジュール１０１と、サーバ装置１０２とを備える。橋梁用三次元桁変位センサモジュール１０１は、位置検出のための電波を受信する複数のアンテナ１０４＿Ａ，１０４＿Ｂからの出力信号に基づいて、当該複数のアンテナ１０４＿Ａ，１０４＿Ｂが対応付けて設けられる橋桁の変位を測定し、当該測定された結果を含む測定情報を無線で送信する。サーバ装置１０２は、測定情報に基づいて、橋梁ＢＲの通行可能性を判定し、当該判定した結果を出力する。【選択図】図１
