To provide a method by which a detection speed of a railway vehicle abnormal travel is increased while a detection accuracy of the abnormal travel is not worsened.SOLUTION: An abnormal travel detection device for a railway vehicle comprises a storage device preliminarily storing at least one initial waveform pattern which is an initial part of an abnormal travel waveform equivalent to a detected signal waveform of a vibration sensor generated during an abnormal travel of the vehicle, a first abnormal travel determiner which calculates the coincidence of a waveform of the detected signal received from the vibration sensor with the initial waveform pattern and determines that an abnormal travel occurs when the coincidence satisfies a prescribed coincidence criteria and a second abnormal travel determiner which determines whether the detected signal received from the vibration sensor satisfies a prescribed abnormal travel condition or not when the first abnormal travel determiner does not determine that the abnormal travel occurs.SELECTED DRAWING: Figure 6
【課題】鉄道車両の異常走行の検知精度を下げることなく、異常走行の検知速度を上げる。【解決手段】鉄道車両の異常走行検知装置は、車両の異常走行時に生じる振動センサの検出信号の波形に相当する異常走行波形のうち初期部分の波形パターンである少なくとも1つの初期波形パターンを予め記憶した記憶器と、前記振動センサから受信した検出信号の波形と前記初期波形パターンとの間の合致度を演算し、その合致度が所定の合致基準を満たすと異常走行が発生したと判定する第1異常走行判定器と、前記第1異常走行判定器により前記異常走行が発生したと判定されない場合に、前記振動センサから受信した前記検出信号が所定の異常走行条件を満たすか否かを判定する第2異常走行判定器と、を備える。【選択図】図6
