PROBLEM TO BE SOLVED: To provide a train passage determination system capable of discriminating train passages in a double track overhead section and train advance directions and accurately determining train intersection (crossing each other).SOLUTION: A train passage determination system comprises at least two sets of vibrometers A,B installed each on the back side of a viaduct below each rail of the incoming line and the downline of a double track overhead section, an oscillation component extraction means 10 that captures each oscillation value detected by these vibrometers A,B on every time and extracts the acceleration component such as the oscillation acceleration level or the oscillation acceleration related to the passage of a rolling stock bogie from the oscillation value from the size of the acceleration component in each rail obtained from the oscillation component extraction means 10, and an operation determination means 11 that determines operation situations such as train passage, the advance direction and the intersection of the train.SELECTED DRAWING: Figure 2
【課題】この発明は、複線高架区間における列車の通過とともに、列車の進行方向の判別と、列車交差(すれ違い)を正確に判定できる列車通過判定システム、列車通過判定方法、及び列車通過判定プログラムを提供するものである。【解決手段】複線高架区間の上り線及び下り線の各レール下方の高架橋の裏側にそれぞれ設置されて各レール上を通過した列車の振動値を検出する少なくとも2組の振動計A・Bと、これら振動計A・Bで検出された各振動値を時間毎に取り込むとともに、該振動値から車両の台車通過に係る振動加速度レベル又は振動加速度等の加速度成分を抽出する振動成分抽出手段10と、該振動成分抽出手段10で得た各レールでの加速度成分の大きさから列車の通過とともに、該列車の進行方向及び交差等の運行状況を判定する運行判定手段11と、を具備することを特徴とする。【選択図】図2
