OPERATOR ANOMALY ASSESSMENT DEVICE AND METHOD

摘要

Disclosed is an operator anomaly assessment device for assessing an anomaly of an operator, provided with a comparison operation anomaly assessment unit for performing a comparison operation using the operator and assessing the existence or non-existence of an anomaly of the comparison operation; and an arithmetic/logic operation anomaly assessment unit for performing an arithmetic/logic operation with a predetermined arithmetic expression including an arithmetic operation and/or a logic operation using the operator, and by performing a comparison operation between the operation result acquired by the arithmetic/logic operation and the stored value of a legal value corresponding to the operation result, assessing the existence or non-existence of an anomaly of the arithmetic/logic operation.
