Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a redundant system capable of improving reliability, and a redundancy method thereof.SOLUTION: Each of a plurality of calculation devices includes a data generation unit and a communication unit. The data generation unit generates current block data including a verification value based on block data at a previous time point, and current history data formed by adding current operation state information of a prescribed detection object to history data at the previous time point. The communication unit exchanges the current block data among the plurality of calculation devices. At least one of the plurality of calculation units includes a function control unit for supplementing a function of the detection object when a failure of a detection object is detected.SELECTED DRAWING: Figure 2
