PROBLEM TO BE SOLVED: To eliminate or alleviate an operation restriction resulting from a communication problem between ground and a train in a radio train control system.SOLUTION: In a radio train control system 1, a plurality of ground radio machines 30 are installed along a rail track R so as to partially overlap their communication area E. A ground processing device 10 extracts information on the range F in charge of each ground radio machine 30 from each of the on-rail information of each train within a controlled range received through each ground radio machine 30, interlocking state information acquired from an interlocking device 70, and temporal speed control information acquired from an operation management device 80, and notifies the ground radio machine 30 of the information as broadcast information about each of ground radio machines 30. Then, each ground radio machine 30 broadcasts the broadcast information notified from the ground processing device 10 within the communication area E at prescribed intervals, and an onboard device 60 determines travel tolerance distance of an own train to perform speed control on the basis of the broadcast information received from the ground radio machine 30.SELECTED DRAWING: Figure 2
【課題】無線式列車制御システムにおいて、地上車上間の通信上の問題に起因する運行制限を無くす或いは緩和すること。【解決手段】無線式列車制御システム1では、線路Rに沿って複数の地上無線機30がその通信エリアEの一部が重なるように設置されている。地上処理装置10は、地上無線機30それぞれについて、各地上無線機30を介して受信した所掌範囲内の各列車の在線情報、連動装置70から取得した連動状態情報、及び、運行管理装置80から取得した臨速制御情報それぞれから、当該地上無線機30の担当範囲Fに関する情報を抽出し、同報情報として当該地上無線機30に通知する。そして、各地上無線機30は、地上処理装置10から通知された同報情報を所定間隔で通信エリアE内に同報し、車上装置60は、地上無線機30から受信した同報情報に基づいて、自列車の走行許容距離を決定して速度制御を行う。【選択図】図2
