PROBLEM TO BE SOLVED: To provide a technology which enables a type of a rolling stock to be determined under various environments.SOLUTION: A large variable temperature part temperature value and a small variable temperature part temperature value are acquired from a part under a floor of a rolling stock. The large variable temperature part temperature value is a temperature value of a large variable temperature part. The large variable temperature part is a part where a temperature change is relatively large out of the variable temperature part where temperature changes during the operation of the rolling stock. The small variable temperature part temperature value is a temperature value of a small variable temperature part. The small variable temperature part is a part where a temperature change is relatively small out of the variable temperature part. A feature amount indicating a feature of the large variable temperature part temperature value is calculated on the basis of the large variable temperature part temperature value. A criterion which is a reference for determining the type of the rolling stock is calculated on the basis of the small variable temperature part temperature value. When the feature amount satisfies the criterion by the comparison of the feature amount with the criterion, a large variable temperature part position is specified on the basis of timing when the large variable temperature part temperature value is acquired, so that the type of the rolling stock is determined in accordance with the specified large variable temperature part position. The large variable temperature part position is a position of the large variable temperature part under the floor of the rolling stock.SELECTED DRAWING: Figure 1

    【課題】様々な環境下で鉄道車両の種別を判定可能な技術を提供する。【解決手段】鉄道車両の床下から大変温部位温度値および小変温部位温度値を取得する。大変温部位温度値は、大変温部位の温度値である。大変温部位は、鉄道車両の運行中に温度が変化する変温部位のうち温度変化が相対的に大きい部位である。小変温部位温度値は、小変温部位の温度値である。小変温部位は、変温部位のうち温度変化が相対的に小さい部位である。大変温部位温度値に基づき、大変温部位温度値の特徴を示す特徴量を算出する。小変温部位温度値に基づき、鉄道車両の種別を判定するための基準である判定基準を算出する。特徴量と判定基準との比較により、特徴量が判定基準を満たす場合に、大変温部位温度値が取得された時機に基づき大変温部位位置を特定し、特定された大変温部位位置に応じて鉄道車両の種別を判定する。大変温部位位置は、鉄道車両の床下での大変温部位の位置である。【選択図】図1
