<p>PROBLEM TO BE SOLVED: To enable all monitored systems to detect the faults of the temporary faulty parts based on the common proper threshold by comparing the temporary failure occurrence frequency of every part of the monitored systems with the common threshold and deciding the occurrence of faults via a monitoring system. SOLUTION: The monitored systems 18A, 18B and 18C send the temporary failure information when the temporary failures which can be automatically recovered occur in these systems. Then a means is added to receive and store the temporary failure information and counts the temporary failure occurrence frequency to compare it with the prescribed threshold. When the temporary failure occurrence frequency is equal to or larger than the threshold, a central control part 12 decides a fault of the relevant parts to register it in a failure history data base 15 and transfers the information to a fault display control part 16 to show it on a display device 17. Then the part 12 notifies the system 18A of the fault of the relevant parts.</p> |
