MONITORING APPARATUS AND MONITORING OBJECT APPARATUS

A monitoring system for monitoring the state of a monitoring object apparatus so as to detect a foretoken of failure. A host computer (100) of a manufacturer/dealer of a clinical check apparatus (200) receives state data of respective parts from parts sensors (203a, 203b, . . .) of the clinical check apparatus (200) of a user and the received state data is compared to a prediction condition stored in a condition storage block (104) in a state monitoring block (105), thereby detecting a foretoken of failure. The prediction condition includes a condition created in accordance with service life of each of the parts and a condition created upon occurrence of a failure in accordance with transition of the state data prior to the occurrence of the failure.
