Abstract

PURPOSE:To shorten the restoring time of a fault system by outputting the weighted answers prepared for recovery of faults in the order of the weight priority and at the same time correcting and changing each weighting of each answer based on the fault recovery result. CONSTITUTION:A diagnostic system 5 analyzes the faults and the answers prepared for the recovery of faults, i.e., the analyzing results are weighted. In this case, the initial value is set according to the importance, for example, of each answer and the weighting is decided by the value obtained based on the hit frequency showing the correct answers and the recovery results. Then the priority is decided in the order of larger weight levels of the weighting. This weighting is however corrected based on the recovery results of faults. Then plural answers having each priority are shown on a display and printed out. As a result, the fault recovering time is shortened in a fault system.

In such a system, if some kind of failure occurs in the computer, which is the main processing unit, processing will stop or the system will stop.

Therefore, maintenance services such as periodic inspections of the system are performed, but since the above-mentioned failures occur in bursts, the user ends up notifying the maintenance service that a failure has occurred in the system, and After a service person from the maintenance service side or the user's side is dispatched to analyze the system failure and install a temporary device, the system failure information is analyzed in a specialized department, and based on the analysis results, predetermined parts etc. are prepared. A service engineer is once again dispatched to the user's site to take measures.

Therefore, since it takes a long time to recover from the occurrence of a system failure, a prompt response is required.

Therefore, a diagnostic system is constructed so that it can be connected to the user's system via, for example, a public network, and the maintenance service side uses the diagnostic system to obtain fault information from the user's system, analyze it, and generate multiple answers as the result of the analysis. Based on this, predetermined parts and the like are prepared, and a service person is dispatched to the user's side to take countermeasures.

However, in the above-mentioned diagnostic system, multiple answers corresponding to the disability information and the disabled child information are statistically accumulated in advance, and the above-mentioned answer is obtained based on the accumulated information, so the answers tend to be biased and are not necessarily correct. (Answer 1 to deal with the problem), and in the end, the system failure could not be recovered by a single dispatch of a service engineer, resulting in the problem that the service engineer would need to be dispatched again. be.

(Problems to be Solved by the Invention) As described above, in the conventional system, there is a problem in that when a failure occurs in a system, it takes a long time to restore the system, making it difficult to provide prompt maintenance services.

(Function) In the present invention, a plurality of answers obtained in order to eliminate a fault that has occurred in the system to be diagnosed and weight information added corresponding to each of these answers are accumulated, and a fault is detected among the plural answers. A predetermined appropriate value is added to the weight information corresponding to the correct answer that solved the problem, and a balance correction value based on the total weight information is added to each weight information of each answer that was not correct to correct each weight information. , In addition, a predetermined correction value is added to the weight information corresponding to a predetermined answer to be corrected among the plurality of answers, and a balance correction value based on all weight information is calculated from each weight information of each answer other than the answer to be corrected. Since each weight information is corrected by subtracting , and this information is fed back to the above-mentioned accumulated information, it is possible to obtain an appropriate answer corresponding to the fault that has occurred, thereby shortening the recovery time of the faulty system. This makes it possible to provide prompt maintenance services.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the overall configuration of a remote maintenance diagnosis system to which a diagnosis system according to an embodiment of the present invention is applied.

As shown in the figure, this system includes a system to be diagnosed 1, which is a user's system, a communication network 3, such as a public network or a private network, which connects the system 1 to be diagnosed via a modem 2, and a communication network 3, such as a public network or a private network. A diagnostic system 5 connected via a modem 4 and diagnosing a fault in the system to be diagnosed l is constructed for 1h.

When a fault occurs in the system to be diagnosed 1, hardware fault information and software fault information are transferred, for example, as binary information, to the diagnostic system 5 via the modem 2, communication network 3, and modem 4. As a result, the diagnostic system 5 analyzes the failure, and obtains a plurality of answers as the analysis results in a predetermined priority order. This allows service personnel to base their answers on priorities.
At fl', predetermined parts and the like are prepared, and the system is dispatched to the system 1 to be diagnosed to perform trouble repair work.

When the fault is recovered, the diagnostic system 5 stores the fault information, the plurality of answers with the above-mentioned priorities for the fault, and information on the correct answer among these answers (answer that resolved the fault). It is accumulated and reflected in the next failure analysis.

Next, the flow of the above-mentioned analysis will be explained using FIG.

As described above, when hardware failure information and software failure information are transferred from the system 1 to be diagnosed where a failure has occurred to the diagnosis system 5 in the form of binary information, the database 6 is referred to and the damage information is determined. mode,
When the error code and error name are determined, the analysis information 1 to n corresponding to the failure is determined.

Then, a group of answers is determined based on each of the above-mentioned factors.

Thereafter, the priority order of the plurality of answers in the answer group is determined, and finally, a plurality of answers with priority order are obtained and outputted, for example, on a display or as a printout. The above-mentioned multiple answers with a priority order are accumulated in the database 6 so as to be reflected in the next failure analysis, and failure recovery is performed based on these multiple answers with a priority order. Restoration results when performing
In other words, the result of which answer among the plurality of answers with priorities was able to repair the fault is also fed back to the database 6.

Next, the determination of priority order in the answer group will be explained using FIG. 3.

As shown in the figure, the answer group K includes a plurality of answers 1 to n, and each of these answers 1 to n is weighted.

The initial value of this weighting is set based on, for example, the importance level of each answer, and is further determined based on the number of correct answers and a value based on the repair results.

Then, the priorities are determined in descending order of weight. Note that the above-mentioned weighting is corrected based on the result of fault repair.

Next, the weighting correction process for each answer will be explained using FIGS. 4 and 5.
