ABNORMALITY MONITORING RECOVERY DEVICE, ABNORMALITY MONITORING RECOVERY METHOD AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an abnormality monitoring recovery device for enhancing the possibility of obtaining a normal final output value more by improving the conventional redundancy mechanism.SOLUTION: N variants 13 perform processing in a parallel manner, and output an intermediate output value 23 (S12). Next, n normality determination parts 14 perform processing in a parallel manner, and output a normality determination result 24 (S13). A determination part 16 confirms whether a variant 13 determined to be "certainly normal" in normality determination exists (S21). In the case that the variant 13 exists (Y of S21), the determination part 16 outputs an intermediate output value 23 of the variant 13 determined to be "certainly normal" as the final output value 25 (S23).
