Abstract

The present invention relates to a system for managing and diagnosing a state of a facility apparatus, and an object thereof is to provide a system for diagnosing the facility apparatus wherein, if information falling under a level of abnormality is extracted from gathered information on an operatingstateof thefacilityapparatus, anadvancedanalysis and diagnosis section on a facility diagnosis center side performs an advanced analysis and diagnosis process and promptly notifies a user side of the information on the best way of dealing with the facility apparatus determined to be abnormal, and further uploads a facility management data analysis program from the advanced analysis and diagnosis section to a facility monitoring section on the user side so that raw information of a large information amount can be analyzed on the user side without sending it to the facility diagnosis center side.

A facility management data processing section (3a) signal-processes facility state detecting information detected by facility state detectors (2a, 2b) mounted on a facility apparatus (1), a facility state determining section (4) determines a level of the signal-processed information comparing with a management reference value and outputs it, the facility monitoring section (5) gathers and processes the information related to the level-determined facility apparatus (1) and sends it to the advanced analysis and diagnosis section (6) via a communication network (10), and the advanced analysis and diagnosis section (6) performs an advanced analysis of the information and identifies a cause of the abnormality of the facility apparatus (1) concerned and improvement measures thereof to send the identified results to the facility monitoring section (5). In addition, it is characterized in that the facility management data analysis program is uploaded from the advanced analysis and diagnosis section (6) to the facility monitoring section (5) so that the advanced analysis can be performed on the user side B.
