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 operating state of the facility apparatus, an advanced analysis 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.

Claims

1. A facility apparatus managing apparatus comprising:

facility management data processing means for signal-processing and outputting facility state detecting information detected by facility state detecting means mounted on a facility apparatus for detecting a state of the facility apparatus;

facility state determining means for determining a level of information outputted from said facility management data processing means comparing with a management reference value and outputting it; and

facility monitoring means for gathering and processing the information related to the facility apparatus level-determined and outputted from said facility state determining means and outputting it to an external apparatus having a function of diagnosing the facility apparatus, wherein said facility monitoring means carries out mutual communication with said external apparatus via a communication network, and downloads a facility management data analysis program from said external apparatus.

2. The facility apparatus managing apparatus according to claim 1, wherein said facility monitoring means downloads a predetermined facility management data analysis program rendered as an electronic file from said external apparatus, and sends the predetermined facility management data analysis program from the electronic file to said facility management data processing means, and the facility management data processing means signal-processes and outputs the facility state detecting information detected by said facility state detecting means by means of said predetermined facility management data analysis program.

3. The facility apparatus managing apparatus according to claim 1 or 2, wherein said facility monitoring means gathers, processes and outputs at least one of maintenance information, operation information and external information from at least one of a maintenance information means, an operation information means and an external information means of said facility apparatus.

4. The facility apparatus managing apparatus according to claim 1, which repeats the steps in which said facility monitoring means downloads the facility management data analysis program from said external apparatus, said facility management data processing means signal-processes and outputs the facility state detecting information detected by said facility state detecting means by using the downloaded facility management data analysis program, said facility monitoring means gathers, processes and outputs the information outputted from the facility management data processing means, and said facility monitoring means receives the results of a predetermined process performed to the information outputted from said facility monitoring means by said external apparatus and the facility monitoring means downloads the facility management data analysis program.

5. The facility apparatus managing apparatus according to claim 1 or 2, wherein said facility monitoring means and said external apparatus are connected by a network, the Internet or a public circuit.

6. The facility apparatus managing apparatus according to claim 1 or 2, wherein said facility monitoring means produces output by attaching abnormality data in the case of abnormality in addition to whether or not there is an abnormality.
