Claims (1)
にワイアードオア接続されるとともにそれぞれ入出力バ
ス選択手段を有する２台の計算機、これら２台の計算機
に対する択一的な入出力バス使用許可信号を出力すると
と−もに少なくとも実作業状態にある方の計算機の動作
状態の監視と自己の動作の診断を行なう二重化制御装置
、及びこの二重化制御装置の出力信号の経路に設けられ
、二重化ル制御装置の出力信号をそのまま２台の計算機
に伝える投入状態と、二重化制御装置の出力信号に無関
係な独自の択一的な入出力バス使用許可信号を２台の計
算機に与える投入状態とを有する手動切換スイッチを具
備する二重化計算機システム。Two computers each having a redundant input/output bus wired or connected to a common redundant input/output bus and each having an input/output bus selection means, and an alternative input/output bus use permission signal for these two computers. A redundant control device that monitors the operating state of the computer that is in the actual working state and diagnoses its own operation, and a redundant control device that is installed in the output signal path of the redundant control device. Manual switching has two states: a closed state in which the output signal of the controller is directly transmitted to the two computers, and a closed state in which a unique, alternative input/output bus usage permission signal unrelated to the output signal of the redundant control device is given to the two computers. A redundant computer system equipped with a switch.
