Abstract

A system for managing and diagnosing a state of a facility apparatus. 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.

Claims

1. A system for diagnosing a facility apparatus comprising:

a facility state detecting means mounted on a facility apparatus for detecting a state of the facility apparatus;

a facility management data processing means for signal-processing and outputting facility state detecting information detected by said facility state detecting means;

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

a facility monitoring means for gathering, processing and outputting the information related to the level of information determined and outputted from said facility state determining means; and

an advanced analysis and diagnosis means for performing an advanced analysis of the information outputted from said facility monitoring means and identifying a cause of an abnormality of the facility apparatus and improvement measures thereof to send the identified results to said facility monitoring means.

2. The system for diagnosing a facility apparatus according to claim 1, wherein said facility monitoring means and said advanced analysis and diagnosis means are capable of mutual communication via a communication network, and a facility management data analysis program is uploaded from said advanced analysis and diagnosis means to said facility monitoring means.

3. The system for diagnosing a facility apparatus according to claim 2, wherein said advanced analysis and diagnosis means diagnoses based on the information outputted from said facility monitoring means, and extracts a predetermined facility management data analysis program from a facility management data analysis program group provided to said advanced analysis and diagnosis means and renders it as an electronic file so as to upload the electronic file to said facility monitoring means via said communication network.

4. The system for diagnosing a facility apparatus according to claim 3, wherein said facility monitoring means sends the predetermined facility management data analysis program from said uploaded 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.

5. The system for diagnosing a facility apparatus according to any one of claims 1 to 3, 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 section, an operation information section and an external information section of said facility apparatus.

6. The system for diagnosing a facility apparatus according to claim 2, wherein by repeating the steps in which the facility management data analysis program is uploaded from said advanced analysis and diagnosis means to said facility monitoring means, 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 uploaded 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 advanced analysis and diagnosis means performs an advanced analysis of the information outputted from said facility monitoring means and identifies a cause of an abnormality of the facility apparatus concerned and improvement measures thereof to send the identified results to said facility monitoring means and also uploads the facility management data analysis program to the facility monitoring means.

7. The system for diagnosing a facility apparatus according to any one of claims 1 to 3, wherein said facility monitoring means and said advanced analysis and diagnosis means are connected by a network, the Internet or a public circuit.

8. The system for diagnosing a facility apparatus according to any one of claims 1 to 3, wherein said facility state detecting means is a portable facility diagnostic measuring apparatus.

9. The system for diagnosing a facility apparatus according to any one of claims 1 to 3, 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.
