PROBLEM TO BE SOLVED: To provide a signal security system that is capable of bringing trains close to each other not at a block boundary but at an optional point.SOLUTION: This signal security system secures safety of train traveling by a mechanism for sharing occupation range information on a track by circulating a security telegram 3 including the occupation range information of each train between on-board devices (train security devices 10) of a train 1 traveling on the track. An occupation range on the security telegram 3 is represented by an absolute position or a relative position from a predetermined reference point, and the on-board device controls an own train not to exceed the occupation range on the condition of overlapping with the occupation range of the other train when the occupation range information of the own train on the telegram 3 is updated.SELECTED DRAWING: Figure 1
【課題】列車同士をブロック境界ではなく任意の地点で接近させることが可能な信号保安システムを提供する。【解決手段】走行路を走行する列車1の車上装置(列車保安装置10)間で、各列車の占有範囲情報を含む保安電文3を回覧させて走行路上の占有範囲情報を共有する仕組みによって列車走行の安全性を確保する信号保安システムにおいて、保安電文3上の占有範囲は、絶対位置もしくは予め決められた基準点からの相対位置で表し、車上装置は電文3上の自列車の占有範囲情報を更新する時に、他列車の占有範囲と重ならないことを条件とし、占有範囲を超えないように自列車を制御する。【選択図】図1
