Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knowledge information processing system, and more particularly to a knowledge information processing system for troubleshooting.

[0002]

2. Description of the Related Art A conventional knowledge information processing system includes a knowledge base in which various kinds of knowledge are stored, a monitoring information / fault information correspondence table in which a correspondence relationship between monitoring information and fault information is described, and this monitoring information.・ A monitoring information / fault information conversion unit that converts the monitoring information from the monitored system into fault information based on the fault information correspondence table, and a fault information from the monitoring information / fault information conversion unit by referring to the knowledge base. It was composed of an inference section that infers the cause of the failure based on the above.

When a failure occurs in the system to be monitored, the monitoring information from the monitoring system is converted into failure information by the monitoring information / failure information conversion section, and the inference section uses the knowledge base based on the failure information. I was inferring the cause by referring to.

[0004]

However, in the above-mentioned conventional example, since the correspondence between the monitoring information and the fault information is fixed, when the correspondence or the information content of both is changed, the system operation is started. There was the inconvenience of having to stop and change the association.

[0005]

The object of the present invention is to improve the inconvenience of the conventional example, and in particular, the knowledge that the monitoring information and the failure information can be associated with each other and the information contents of both can be changed or added at any time without stopping the operation of the system. To provide an information processing system.

[0006]

Therefore, according to the present invention, a knowledge base in which various kinds of knowledge are stored, a monitoring information / fault information correspondence table in which a correspondence relationship between monitoring information and fault information is described, and a monitoring Questions related to the failure information from the monitoring information / failure information conversion section that refers to the monitoring information / failure information conversion section that converts the monitoring information from the monitored system into failure information based on the information / failure information correspondence table To the user, an answer input means for inputting the answer from the user, an inference section for inferring the cause of the failure based on the answer from the answer input means with reference to the knowledge base, and this inference section The configuration is provided with a cause output unit that outputs the obtained inference result and a correspondence table input unit that changes / adds the contents of the monitoring information / fault information correspondence table.
This aims to achieve the above-mentioned object.

[0007]

When any failure occurs in the target system, the monitoring information of the target system is notified to the monitoring information / fault information conversion section. Then, the monitoring information / fault information conversion unit refers to the monitoring information / fault information correspondence table and converts the monitoring information into fault information. Further, the monitoring information / fault information conversion unit outputs the converted fault information to the question output means.

The question output means refers to the knowledge base 7,
Notify the user of any questions regarding the entered fault information. The user inputs the answer to the question from the question output means to the answer input means.

When the answer input to the answer input means is notified to the inference unit, the inference unit refers to the knowledge base to infer the cause of the failure. Then, the inference unit outputs the obtained cause information to the cause output means and reports it to the user.

The monitoring information / fault information correspondence table can be changed / added by the user from the correspondence table input means.

[0011]

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described below with reference to FIG.

In the embodiment of FIG. 1, a knowledge base 7 in which various kinds of knowledge are stored, and a monitoring information / fault information correspondence table 11 in which a correspondence relation between the monitoring information 9 and the fault information 10 is described.
And a failure information from the monitoring information / failure information conversion unit 8 and a monitoring information / failure information conversion unit 8 for converting the monitoring information 9 from the monitored system into the failure information 10 based on the monitoring information / failure information correspondence table 11. Fault information input section 6 for inputting 10
And the question output means 2 for asking the user a question regarding the fault information 10 from the fault information input section 6 by referring to the knowledge base 7.
The answer input means 3 for inputting the answer from the user, the inference section 4 for inferring the cause of the failure based on the answer from the answer input means 3 by referring to the knowledge base 7, and the inference section 4. The reason output means 5 outputs the inference result and the correspondence table input means 1 for changing / adding the contents of the monitoring information / fault information correspondence table 11.

Here, the correspondence table input means 1 uses the monitoring information 9
The correspondence table input screen 1B in which the user specifies the correspondence between the failure information 10 and the monitoring information / fault information correspondence table 11 in which data from the correspondence table input screen 1B is stored in the monitoring information / fault information correspondence table 11.
It is composed of a failure information correspondence table input section 1A.

Further, the question output means 2 comprises a question screen output section 2A for displaying a question regarding the fault information 10 on the question screen 2B by referring to the knowledge base 7.

B and.

Next, the operation of this embodiment will be described.

.. If something goes wrong with the target system,
From the monitoring device of the target system, the monitoring information 9
The failure information conversion unit 8 is notified.

.. The monitoring information / fault information conversion unit 8 refers to the monitoring information / fault information correspondence table 11 and converts the monitoring information 9 from the monitoring device of the target system into fault information 10. For example, the monitoring information 9 expresses the alarms of the monitoring station and the like by numerical values, and the failure information 10 required by the knowledge information processing system.
Is the character information indicating the state of the target device, the monitoring information / fault information conversion unit 8 converts numeric data to character data and associates the relevant monitoring information with the fault information.

Further, the monitoring information / fault information converting section 8 is
The converted fault information 10 is output to the fault information input unit 6.

[0021]. The fault information input unit 6 notifies the question screen output unit 2A of the fault information 10 input from the monitoring information / fault information conversion unit 8.

.. When the question screen output unit 2A receives the fault information 10 from the fault information input unit 6, the question screen output unit 2A refers to the knowledge base 7 and asks questions about items necessary for inferring the cause of the fault information 10 on the question screen 2B. indicate.

.. The user inputs the answer to the question displayed on the question screen 2B on the answer input screen 3B.

[0024]. The answer entered in the answer input screen 3B is taken in by the question answer input unit 3A and notified to the inference unit 4.
