Zusammenfassung: | To provide a train position specifying method by which a train position is accurately specified even in a section where verifying measured curvature data with stored ones is easy or in a section that is difficult.SOLUTION: A train position specifying method comprises a step S11 of acquiring measured curvature data, a step S12 of extracting stored curvature data part whose degree of the deviation from measured curvature data is minimal and acquiring the degree of the deviation of the extracted part from the measured curvature data as the minimum value of the deviation degree and a step S13 of specifying a train position based on a distance position at the minimum deviation degree part when the minimum deviation degree value is equal to or less than a threshold value TD1 and specifying the train position based on a calculated travel distance when the minimum deviation degree value surpasses the threshold value TD1.SELECTED DRAWING: Figure 3
【課題】曲率の記憶データと曲率の測定データとの照合が容易な区間でも困難な区間でも列車の位置を精度良く特定することができる列車位置特定方法を提供する。【解決手段】列車位置特定方法は、曲率の測定データを取得するステップS11と、曲率の記憶データのうち曲率の測定データとの乖離度が最小になる部分を抽出し、抽出された部分と曲率の測定データとの乖離度を乖離度の最小値として取得するステップS12と、乖離度の最小値が閾値TD1以下の場合、列車の位置を、乖離度が最小になる部分における距離位置に基づいて特定し、乖離度の最小値が閾値TD1を超えた場合、列車の位置を、算出された走行距離に基づいて特定するステップS13と、を有する。【選択図】図3 |
