Abstract

PURPOSE:To make a person in charge of maintenance perform maintenance similar to a specialist by storing messages outputted from an objective device of diagnosis and maintenance, making statistical processing on them, and indicating operation deduced utilizing statistical information and knowledges of diagnosis and maintenance of stored knowhow of specialists to a person in charge of maintenance. CONSTITUTION:Messages of the state of system outputted from an objective device of diagnosis and maintenance are stored in a message storage device 3. Stored messages are processed statistically and stored in a message information statistics storage device 4. Message statistics information is collated with a diagnosis and maintenance knowledge storage device 6 in which knowhow of specialists who make diagnosis and maintenance is stored in form of rules by a deducing means 5, and an operation to be executed by a person in charge of maintenance is determined. The deduced operation is indicated to the person in charge of diagnosis and maintenance by a diagnosis and maintenance operation indication outputting device 7. Thus, diagnosis and maintenance similar to expert specialists can be executed.

Description

DETAILED DESCRIPTION OF THE INVENTION 1. Field of Industrial Application The present invention relates to a diagnostic maintenance device for electronic equipment, typified by a storage program type time-sharing electronic exchange.

Since then, electronic devices, such as storage program type time-sharing electronic switching systems, have been used as devices for diagnostic maintenance to print out system status messages that indicate the status of the device and the occurrence of failures. It is equipped only with a message output device. Therefore, diagnostic maintenance of equipment subject to diagnostic maintenance should be carried out in accordance with "NEC (TLO, Near Sox 61 Digital Switching System Maintenance Manual, IQ 83)".

1 Problems to be Solved by the Invention Diagnosis and maintenance of electronic equipment (complex as an electric switchboard) that is used in the public domain and requires quick failure recovery requires extremely sophisticated maintenance. Specialized knowledge is required, and in order to find such specialized knowledge, a long period of education and experience are required. 1. It costs a huge amount of money to train a single-minded expert. Requires.

The purpose of the present invention is to provide maintenance services that can be used by less skilled maintenance personnel.
In order to be able to carry out diagnostic maintenance on a par with maintenance experts, we have accumulated the knowledge of a skilled maintenance specialist, and we analyze system status messages output from the target equipment to quickly take the next action. An object of the present invention is to provide an electronic device diagnostic maintenance device that can provide instructions.

Means for Solving Problem 1] The electronic equipment diagnostic maintenance device of the present invention includes a message storage device that receives and stores system status messages output from the diagnostic maintenance target device, and a message storage device that statistically processes and stores the messages. A message information statistics storage device, a diagnostic maintenance knowledge storage device that stores the know-how of experts who perform diagnostic maintenance using this message statistical information, and a maintenance personnel knowledge storage device that uses the message statistics information and the FS 1lli maintenance knowledge j81i. It consists of a discussion means for determining the operation to be taken, and a diagnostic maintenance operation instruction output device for instructing the maintenance person on the inferred operation.

1 Effect 1 Constantly memorizes messages output from the device to be diagnosed.1. Statistical processing is performed depending on the message type and parameters, and the data is stored. The results of this statistical processing are constantly monitored by inference means and compared with experts' know-how organized in the form of rules.

When the condition part of the rule is met, the action part of the rule is executed to instruct the maintenance person on the action to be taken.Embodiment 1 The present invention will be described below with reference to the drawings. do.

In FIG. 1 showing an embodiment of the present invention, the diagnostic maintenance pair 7ρ
System status messages output from the device are 1. The message is stored in the message storage device 3. The stored messages are statistically processed and stored in the message information statistics storage device 4. The message statistical information is compared by the inference means 5 with the diagnostic maintenance rll & storage device 6 which stores the know-how of experts who perform diagnostic maintenance in the form of rules, and it is determined which operation the maintenance person should take. The inferred operation is instructed to the diagnostic maintenance person by the diagnostic maintenance operation instruction output device 7.

The 11-monka-me know-how is written in the form of a rule: "If conditional part), then (action part)."

For example, one of the pieces of knowledge in an electronic switchboard is, ``If message A occurs on trunk B more than 5 times per minute, then (block trunk B3 and connect the line to 16
It can be expressed as "Please understand."

FIG. 2 shows a flowchart for executing the inference means 5 which performs inference using the knowledge thus expressed. Note that P1 to P4 in the figure indicate each step of the flowchart. In Pl, one rule is selected, and in P2, the condition part of the rule is checked against the message statistical information. If no information matching the conditions was found in P3, click P3.
Return to step 1 and choose the next rule. If it matches the conditional part, the action part is executed with 1)=1, and F'1 is also set. By repeating such operations, the diagnostic work 1 is realized in which messages are constantly monitored and appropriate instructions are given.

(Effects of the Invention) As described above, according to the present invention, the system status message output from the target device is analyzed and the next operation to be performed is determined as quickly as a skilled maintenance expert. Therefore, even less skilled maintenance personnel can perform diagnostic maintenance equivalent to that of skilled maintenance experts.
