PROBLEM TO BE SOLVED: To provide a railway security system that shortens a period of time locking for a track circuit belonging to a travel route of a train and thereby enhances operation efficiency.SOLUTION: An interlocking device, which controls on-site installations belonging to a travel route of a train, includes a controller. The controller controls locking or unlocking of plural track circuits that detect presence or absence of the train on a rail among the on-site installations, and locks specific track circuits including a time locking track circuit related to a point on a condition that the point is opened to the time locking track circuit side. Among the specific track circuits, the locking is continued for the track circuit having detected no train present thereon, while the track is locked due to approaching train or the rearward track circuit is locked, but otherwise, the locking is released on a condition that the track circuit is not the time locking track circuit, and the time locking is started on a condition that the track circuit is the time locking circuit. During time locking, when the train is confirmed not to be present in the time locking track circuit, from on-rail position information transferred from an on-rail position information reception device of the train, the time locking track circuit is unlocked.SELECTED DRAWING: Figure 1

    【課題】列車の走行ルートに属する軌道回路の時間鎖錠を短縮し、運行効率を高める保安システムを提供する。【解決手段】列車の走行ルートに属する現場設備を連動して制御する連動装置はコントローラを備え、現場設備のうち列車の在線有無を検知する複数の軌道回路に対する鎖錠又は解錠を制御し、転てつ器に関連する時間鎖錠用軌道回路を含む特定の軌道回路を、転てつ器の時間鎖錠用軌道回路側への開通を条件に鎖錠する。特定の軌道回路のうち、列車の不在を検知した軌道回路に対し、接近鎖錠中または後方軌道回路が鎖錠中の場合は鎖錠を継続し、それ以外の場合、軌道回路が、時間鎖錠用軌道回路でないことを条件に軌道回路を解錠し、時間鎖錠用軌道回路であることを条件に時間鎖錠を開始する。時間鎖錠中に、列車の在線位置情報受信装置より転送された在線位置情報から、時間鎖錠用軌道回路内の列車の非在線が確認された場合は、時間鎖錠用軌道回路を解錠する。【選択図】図1
