BRIDGE MONITORING SYSTEM, BRIDGE MONITORING METHOD, AND PROGRAM
PROBLEM TO BE SOLVED: To determine soundness of a bridge with a simplified measurement system.SOLUTION: A bridge monitoring system comprises: a plurality of sensor units that are mounted on a mobile body moving on a bridge girder of a bridge in a main girder direction so that the units apart from each other and measure vibration in a predetermined direction at respective mounted positions; and a data formation unit that sets a target position to be evaluated which is an evaluation target position of the bridge, at a specific position in the extending direction of the bridge main girder and extracts time history data within a predetermined time range related to time at which a sensor unit passes through, from each of pieces of time history data measured by the respective sensor units, and creates time history data on a measurement value of vibration at the target position to be evaluated by connecting the extracted pieces of time history data in order according to time series.
【課題】測定系を簡素化して橋梁の健全性を判定する。【解決手段】橋梁の橋桁上を主桁方向に移動する移動体に、前記移動体の移動方向に距離を隔てて搭載され、前記搭載されたそれぞれの位置で、予め定められた方向の振動を測定する複数のセンサ部と、橋梁の主桁の延伸方向の特定の位置に、当該橋梁の評価対象の位置である被評価対象位置を定め、前記各センサ部により測定された時刻歴データのそれぞれから、前記センサ部が前記被評価対象位置を通過する時刻に係る所定の時間範囲の時刻歴データを抽出するとともに、前記抽出した時刻歴データを時系列に応じた順に繋ぎ合わせることにより前記被評価対象位置における振動の測定値の時刻歴データを生成するデータ編成部と、を備える。【選択図】図１
