Zusammenfassung: | To determine whether facilities are normal according to presence or absence of maintenance operation by determining whether the facilities are under maintenance operation on the basis of measurement data obtained by measuring the facilities that may be maintained.SOLUTION: An acquisition portion 111 acquires a measurement value and a learning model M. A normal state determination part 112 classifies acquired measurement values as normal or not by using a normality determination model. A maintenance operation determination portion 113 classifies measurement values classified as abnormal as those showing maintenance operation or not by using a maintenance operation determination model. A maintenance normal state determination portion 114 classifies measurement values that are classified as abnormal and as those showing maintenance operation as normal maintenance operation or not by using a maintenance normality determination model. A fault sign determination part 115 analyzes appearance patterns of measurement values and determines whether states of facilities J have a sign of a fault. An output portion 116 outputs determination results to a presentation/instruction device 6.SELECTED DRAWING: Figure 4
【課題】保守作業が行われ得る設備を計測した計測データに基づいて、その設備が保守作業中であるか否かを判定し、保守動作の有無に応じてその設備が正常であるか否かを判定する。【解決手段】取得部111は、計測値、学習モデルMを取得する。正常状態判定部112は、正常判定モデルを用いて、取得した計測値を正常か否かに分類する。保守動作判定部113は、保守動作判定モデルを用いて、正常でないと分類された計測値を、保守動作を示すものか否かに分類する。保守正常状態判定部114は、保守正常判定モデルを用いて、正常でないと分類され、保守動作を示すものであると分類された計測値を正常な保守動作か否かに分類する。故障予兆判定部115は、計測値の出現パターンを解析して、設備Jの状態に故障の予兆があるか否かを判定する。出力部116は、判定結果を、それぞれ提示指示装置6に出力する。【選択図】図4 |
