<p>PURPOSE:To prevent the wrong correction due to a wrong diagnosis by switching the diagnostic result of an abnormality diagnosing device between a mode where the diagnostic result is outputted to the control output as a correction signal and a mode where the diagnostic result is directly outputted. CONSTITUTION:An abnormality diagnosing device 4 stores an equipment 9 and its operating method in a knowledge base 5 and diagnoses the symptom of abnormality of a plant or the generating situation of the abnormality via an inference means 6 based on the present operation data and the base 5. At the same time, a mode switch means 8 performs freely the switch between a control mode where the diagnostic result is outputted to a correction means 3 as a correction signal S2 and a diagnostic mode where the diagnostic result is directly outputted. Then the diagnostic result is outputted via a diagnostic result output means 7. The means 8 performs the switchover between those two modes in response to the state of abnormality and based on the mode information on each abnormality state set previously. Thus the diagnostic result is outputted to a CRT or a voice means in a diagnostic mode and then to a correction means 3 when in a control mode respectively.</p> |
