To provide a state monitoring device for a railway vehicle capable of easily determining the existence/nonexistence of abnormality of a railway vehicle with high accuracy.SOLUTION: A railway vehicle state monitoring device 100 includes a detection device 1 for detecting an index represented by the wheel weight of a wheel 31 included in a railway vehicle 3 traveling on a track, and a determination device 2 for determining the existence/nonexistence of abnormality of the railway vehicle on the basis of a plurality of indexes detected within a prescribed time and maintenance information of an inputted track or railway vehicle. The determination device includes a classifier 21 which is generated by machine learning, receives a plurality of indexes, and outputs the existence/nonexistence of maintenance. The determination device determines normality when an output of the classifier has no maintenance. When the output of the classifier has maintenance, the determination device determines whether maintenance is actually performed on the basis of maintenance information, and determines that the railway vehicle is normal when the maintenance is actually performed and that abnormality occurs when the maintenance is not performed.SELECTED DRAWING: Figure 2

    【課題】鉄道車両の異常の有無を簡易に且つ精度良く判定することが可能な鉄道車両の状態監視装置を提供する。【解決手段】鉄道車両状態監視装置100は、軌道上を走行する鉄道車両3が具備する車輪31の輪重で表わされる指標を検出する検出装置1と、所定時間内に検出した複数の指標と、入力された軌道又は鉄道車両のメンテナンス情報とに基づき、鉄道車両の異常の有無を判定する判定装置2とを備える。判定装置は、機械学習によって生成され、複数の指標が入力され、メンテナンスの有無を出力する分類器21を具備する。判定装置は、分類器の出力がメンテナンス無しの場合、正常であると判定する。分類器の出力がメンテナンス有りの場合、メンテナンス情報に基づき、メンテナンスが実際に行われたか否かを判定し、実際に行われているときには正常であり、行われていないときには異常が生じていると判定する。【選択図】図2
