METHOD FOR OBSERVING GROUND DISPLACEMENT, AND INFORMATION PROCESSOR

PROBLEM TO BE SOLVED: To detect ground displacement with high accuracy in a simple configuration.SOLUTION: An information processor (a gateway device 20, and a server device 30) stores values obtained by measuring vectors of inclination angles (displacement angles) about a plurality of respective inclination sensors 10 installed within a prescribed area 2 where ground displacement is observed in a time series manner, acquires components in a perpendicular direction to an inclination vector due to disturbance among inclination vectors due to ground displacement about each vector before and after time series changes, calculates an average of sizes of components in the perpendicular direction about each inclination sensor 10, and generates information about inclinations due to the ground displacement in the area 2 on the basis of the calculated value.SELECTED DRAWING: Figure 21 【課題】簡素な構成にて精度よく地盤変位を検知する。【解決手段】情報処理装置（ゲートウェイ装置２０，サーバ装置３０）が、地盤変位の観測が行われる所定のエリア２内に設置した複数の傾斜センサ１０の夫々について傾斜角（変位角）のベクトルを時系列的に計測した値を記憶し、時系列的な変化の前後の各ベクトルについて、地盤変位による傾斜ベクトルのうち、外乱による傾斜ベクトルに対して垂直な方向の成分を求め、各傾斜センサ１０について求めた垂直な方向の成分の大きさの平均を求め、求めた値に基づきエリア２における地盤変位による傾斜に関する情報を生成する。【選択図】図２１
