To provide a train security system configured to be able to specify a travel speed of a vehicle with high accuracy, even if sliding of a wheel and idling of a wheel occur.SOLUTION: The train security system comprises: a control device 6 that controls movement of a vehicle 8 on the basis of a block section and an on-rail position X of the vehicle 8 in the block section; a first device 1 that detects rotation of at least one of a wheel 4 and a wheel axis of the wheel 4 and outputs the rotation as a first detected value P1 to the control device 6; and a second device 2 that inputs second detected values P2 and P3 of movement states of the vehicle 8 to the control device 6. The control device 6 calculates a speed V of the vehicle 8 on the basis of the first detected value P1, calculates a movement distance L of the vehicle 8 on the basis of the speed V, calculates the on-rail position X of the vehicle 8 on the basis of the movement distance L, detects sliding or idling of the wheel 4 on the basis of the first detected value P1, and when detecting the sliding or the idling, corrects the speed V of the vehicle 8 on the basis of the second detected values P2 and P3 during the sliding or the idling.SELECTED DRAWING: Figure 1

    【課題】 車輪の滑走、車輪の空転が生じても、車両の走行速度を高い精度で特定できる、列車保安システムを提供する。【解決手段】 閉塞区間と閉塞区間における車両8の在線位置Xとに基づいて、車両8の移動を制御する制御装置6と、車輪4、及び、車輪4の車軸の少なくとも一方の回転を検出して第1の検出値P1として制御装置6に出力する第1の装置1と、車両8の移動状態を検出した第2の検出値P2,P3を制御装置6に入力する第2の装置2と、を備え、制御装置6は、第1の検出値P1に基づいて、車両8の速度Vを算出し、速度Vに基づいて、車両8の移動距離Lを算出し、移動距離Lに基づいて、車両8の在線位置Xを算出し、第1の検出値P1に基づいて、車輪4の滑走又は空転を検出し、そのように滑走又は空転を検出したならば、その滑走又は空転の間車両8の速度Vを第2の検出値P2,P3に基づいて補正する。【選択図】図1
