To detect occurrence of failure in a detector at the time of passing.SOLUTION: In an overrun prevention device 100, a trains stop control device 130 includes: a passing time failure detection unit 133 for detecting that, after a first signal from a first detector 1A-1, 2 is in a non-detection state and a second signal from a second detector 1B-1, 2 is in a non-detection state, a combination of changes of a first signal state and a second signal state, which are sequentially changed in accordance with the passage of trucks 30-1, 2, corresponds to a predetermined failure condition that is contradictory to the changes in signal states in accordance with a magnitude relationship between a longitudinal axle interval and a detector interval; and a failure notification control unit 137 for issuing a predetermined failure notification in accordance with the detection of the passing time failure detection unit 133.SELECTED DRAWING: Figure 1
【課題】検知子に係る通過時故障の発生を検出すること。【解決手段】過走防止装置100において、列車停止制御装置130は、第1の検知子1A-1,2からの第1の信号が非検知状態であり、且つ、第2の検知子1B-1,2からの第2の信号が非検知状態の後に、台車30-1,2の通過に伴って順番に変化する第1の信号の状態と第2の信号の状態との変化の組み合わせが、前後車軸間隔と検知子間隔との大小関係に従った信号状態の変化に矛盾する所定の故障条件に相当することを検出する通過時故障検出部133と、通過時故障検出部133の検出に応じて所定の故障通知を行う故障通知制御部137と、を備える。【選択図】図1
