RAILWAY TRACK ABNORMALITY DETERMINATION METHOD AND ABNORMALITY DETERMINATION SYSTEM
To provide an abnormality determination method and an abnormality determination system by which abnormalities including a derailment possibility are determined by a single measurement by using data measurable on board and digitizing the statistic features of the measured data.SOLUTION: An abnormality determination method to evaluate an abnormality existence of a rail on which a railway vehicle travels includes a data acquisition step to acquire more than one onboard measurement data using measurement means installed in said railway vehicle, an abnormality degree calculation step to calculate an abnormality degree from said onboard measurement data and an evaluation step to evaluate an existence of the track abnormality from the abnormality degree calculated in said abnormality calculation step.SELECTED DRAWING: Figure 3
【課題】車上で測定することが可能なデータを用いて、当該測定データの統計的な特徴を数値化することで、一度の測定で脱線可能性を含む異常を判定することができる異常判定方法及び異常判定システムを提供する。【解決手段】鉄道車両が走行する軌道の異常の有無を評価する異常判定方法であって、前記鉄道車両に備える測定手段を用いて２以上の車上測定データを取得するデータ取得工程と、前記車上測定データから異常度を算出する異常度算出工程と、前記異常度算出工程で算出された異常度から軌道の異常の有無を評価する評価工程と、を備える。【選択図】図３
