PROBLEM TO BE SOLVED: To accurately detect a temperature anomaly generated in an underfloor apparatus installed on the underfloor of a railway vehicle.SOLUTION: A temperature anomaly detection system acquires an apparatus temperature value which is a temperature value of an underfloor apparatus, and accumulates the acquired apparatus temperature value. The correlation between the underfloor apparatuses is acquired from the apparatus temperature value to be accumulated, and a correlation coefficient is calculated based on an acquired correlation. The correlation coefficient is acquired from the apparatus temperature value to be accumulated with the apparatus temperature value of a determination object apparatus which is the underfloor apparatus desiring for the determination of the temperature anomaly as a determination temperature value. A proper temperature value is predicted from the apparatus temperature value based on the acquired correlation. The proper temperature value is a proper temperature value when the temperature anomaly is not generated in the determination object apparatus. When a deviation which is a value in which the determination temperature value deviates from the proper temperature value is larger than an anomaly determination threshold value as a result of the comparison between the determination temperature value and the proper temperature value, the anomaly determination for determining that the anomaly temperature is generated in the determination object apparatus is performed. An anomaly determination threshold value is the threshold value for determining that the temperature anomaly is generated in the determination object apparatus.SELECTED DRAWING: Figure 1
【課題】鉄道車両の床下に設置される床下機器に発生する温度異常を精度良く検出する。【解決手段】床下機器の温度値である機器温度値を取得する。取得された機器温度値を蓄積する。蓄積する機器温度値から床下機器間の相関関係を取得し、取得した相関関係に基づき相関係数を計算する。温度異常の判定を所望する床下機器である判定対象機器の機器温度値を判定用温度値として、蓄積する機器温度値から取得する。取得された相関関係に基づき、機器温度値から、適正温度値を予測する。適正温度値は、判定対象機器に温度異常が発生していない際の適正な温度値である。判定用温度値と適正温度値との比較により、判定用温度値が適正温度値から乖離する値である乖離値が、異常判定閾値よりも大きい場合に、判定対象機器に温度異常が発生していると判定する異常判定を行う。異常判定閾値は、判定対象機器に温度異常が発生していると判定するための閾値である。【選択図】図1
