PROBLEM TO BE SOLVED: To provide a track circuit state determining device that decides the correctness of a state change of a track circuit even about a terminal track in addition to a normal track.SOLUTION: An adjacent track circuit specific value (1T and 3T or 2T and 4T) is set in the data item of a left side track and a right side track, if a target track is the normal track (2T and 3T), or a boundary track specific value or a dead end track specific value is set in the data item of the left side track out of a vehicle tracking range if the target track is the terminal track (1T), about track circuit regulation data 14 for identifying a logical state and an adjacent track circuit of both sides every target track. A track circuit state determination program 13 determines a logical state of the target track circuit on the basis of a vehicle tracking processing logic if the target track is a normal track or a dead end track. Alternatively, a vehicle tracking processing logic is avoided and logical state of the target track circuit is determined if the target track is the boundary track. As a result, the correctness of the state change of the track circuit is decided about the dead end track among terminal tracks, and erroneous determination in the train intercommunication can be avoided about the boundary track among the terminal tracks.SELECTED DRAWING: Figure 1
【課題】通常軌道に加えて端末軌道についても軌道回路の状態変化の正当性を判断する。【解決手段】対象軌道毎に論理状態と両脇の隣接軌道回路を特定する軌道回路規定データ14については、対象軌道が通常軌道(2Tや3T)であれば左側軌道と右側軌道のデータ項目に隣接軌道回路特定値(1Tと3Tや2Tと4T)を設定するが、対象軌道が端末軌道(1T)であれば車両追跡範囲外の左側軌道のデータ項目に境界軌道特定値か行止軌道特定値を設定する。軌道回路状態判別プログラム13は、対象軌道が通常軌道か行止軌道であれば車両追跡処理論理に基づいて対象軌道回路の論理状態を判別する一方、対象軌道が境界軌道であれば車両追跡処理論理を回避して対象軌道回路の論理状態を判別する。これにより、端末軌道のうち行止軌道については軌道回路の状態変化の正当性が判断されるとともに、端末軌道のうち境界軌道については列車往来時の誤判定が避けられる。【選択図】 図1
