To shorten a time required for loading in a signal security system of a railway.SOLUTION: In a signal security system 1 of a railway, when a supervising device 10 sends a switching instruction for switching to a data control mode to respective logic devices 20, the respective logic devices 20 transit to the data control mode in accordance with the switching instruction, and change an allocation of a storage position of data in a communication frame circulating in LAN 30 to an allocation for the data control mode in which an allocation, as a storage position of LD information (LD data or an LD program) sent and received in the data control mode, of a storage position, to which information (information regarding signal security) sent and received in a normal mode is allocated, is changed. In the data control mode, the supervising device 10 and the logic device 20 sends and receives the LD information on the basis of the determination that the allocation for the data control mode is applied to the communication frame.SELECTED DRAWING: Figure 1

    【課題】鉄道用信号保安システムにおいて、ローディングに要する時間を短縮すること。【解決手段】鉄道用信号保安システム1において、監理装置10が各論理装置20に対してデータ管理モードへの切替指示を送信すると、各論理装置20は、切替指示に従ってデータ管理モードへ遷移するとともに、LAN30を周回する通信フレームにおけるデータの格納位置の割り付けを、通常モードにおいて授受される情報(信号保安に係る情報)が割り付けられている格納位置を、データ管理モードにおいて授受されるLD情報(LDデータやLDプログラム)の格納位置として割り付けを変更したデータ管理モード用割り付けに変更する。データ管理モードでは、監理装置10及び論理装置20は、通信フレームにデータ管理モード用割り付けが適用されると判断して、LD情報を授受する。【選択図】図1
