Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a main cause determination processing method for determining a true fault location from a plurality of pieces of fault information in a centralized monitoring device.

Conventional technology Conventionally, the main cause determination method that determines the true fault location from multiple pieces of fault occurrence information defines multiple pieces of fault occurrence information and the true fault location for that, and also adds information on the frequency of occurrence of the fault location. Judgment file, time aggregation means for aggregating information on multiple failures occurring at the same time that are randomly (or irregularly) notified due to transmission delays, etc., and failures aggregated by the time aggregation means. A main cause determination logic means that determines the true failure part by searching the main cause determination file based on the occurrence information, and a main cause determination logical means that determines the true failure part by searching the main cause determination file based on the true failure part information determined by the main cause determination logic means. The main cause additional information processing means updates the occurrence frequency information of the part, and the main cause determination logical means always compares the multiple pieces of failure occurrence information defined in the main cause definition file by the maintainer with the true failure part. The true fault location was determined based on the response and the occurrence frequency information of the main cause determination file updated by the main cause additional information processing means.

Problems to be Solved by the Invention The main cause determination logical means in the conventional main cause determination processing method always corresponds between multiple failure occurrence information defined in the main cause determination file by a maintenance person and the true failure part, and determines the main cause. Since the true failure part is determined based on the occurrence frequency information of the main cause determination file updated by the additional information processing means, the occurrence of the main cause determination file is performed based on the true failure part information determined by the main cause determination logic means. Frequency information is updated. Therefore,
When the main cause determination logic means makes an erroneous determination, the occurrence frequency information is updated with the erroneous failure part information, so there is a problem that the probability of making an erroneous determination thereafter increases.

The present invention has been made in view of the above-mentioned conventional circumstances,
Accordingly, an object of the present invention is to provide a novel main cause determination processing method that makes it possible to solve the above-mentioned problems inherent in the conventional technology.

Means for Solving the Problems In order to achieve the above object, the main cause determination processing method for determining the true failure part from a plurality of failure information according to the present invention is as follows:
A main cause determination file that defines multiple failure occurrence information and the true failure location, and adds information on the occurrence frequency of the failure location, and a file that defines the occurrence frequency of failure locations, and detects occurrences at the same time when notifications are sent randomly (irregularly) due to transmission delays, etc. a time aggregation means for aggregating a plurality of pieces of failure occurrence information; a main cause determination logical means for determining a true failure part from the aggregated failure occurrence information and the main cause determination file; A main cause additional information processing means for updating the frequency of occurrence information in the main cause judgment file, and a main cause additional information processing means for notifying the operator of the true failure part determined by the main cause judgment logic means, and for the operator to confirm whether the failure part is good or bad. The apparatus for receiving a judgment instruction includes a judgment result user interface means for notifying the main cause additional information processing means of the content of the judgment instruction.

Embodiment Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a flowchart showing one embodiment of the present invention.

Referring to FIG. 1, one embodiment of the present invention includes receiving means 1
, a time aggregation means 2 , a main cause determination logic means 3 , a main cause additional information processing means 4 , a determination result user interface means 5 , and a main cause determination file 6 .

FIG. 2 is a diagram showing an example of the main cause determination file 6.

Referring to FIGS. 1 and 2, in the receiving means 1, step A1 waits for information to be received, and upon reception, notifies step A2. If the received information is failure occurrence information, step A2 is a time aggregating means. 2, and if it is timeout notification information, the main cause determination logic means 3 is notified.

In the time aggregation means 2, step B1 determines, based on the failure occurrence information notified from the receiving means 1, whether the timeout has already been requested or whether a timeout request is necessary. Notify other systems of notification information requests.

In the main cause determination logic means 3, step C1 detects failure occurrence information by searching the current status table defined in another system based on the timeout notification information notified from the receiving means 1, and notifies step C2. . Step C2 assigns a weight F defined in the main cause determination file 6 to the detected failure occurrence information.
3 is searched, the total value of the weighting F3 of each faulty part F2 is calculated, and the faulty part F2 having the largest total value is determined to be the true faulty part. At this time, if there are a plurality of maximum total values, the faulty part F2 with the highest occurrence frequency F4 of each faulty part F2 is determined to be the true faulty part. Furthermore, step C2 notifies the main cause additional information processing means 4 of the determination result.

In the main cause additional information processing means 4, step DI determines that the judgment result of the main cause judgment logic means 3 is a positive judgment result and that the judgment result of the judgment result user interface means 5 is a negative judgment result or a positive judgment result. Notify step D2. In step D2, when a positive determination result is received, the occurrence frequency F4 corresponding to the relevant failure part of the main cause determination file 6 is processed.
is counted up, and when a negative judgment result is received, the occurrence frequency F4 corresponding to the corresponding failure part in the main cause judgment file 6 is counted up.
count down. Furthermore, step D2 notifies the determination result user interface means 5 of the determination result.

In the determination user interface means 5, step E
1 displays the determination result notified from the main cause additional information processing means 4. In step E2, an input is displayed for instructing whether the true failure part displayed in step E1 is correct or erroneously determined, and the process enters a state of waiting for an input. If the operator's input is a negative instruction, step E3 determines that the main cause determination result is an erroneous determination, and counts down the frequency of occurrence F4 of the relevant failure part in the main cause determination file 6, or calculates the failure part specified by the operator. In order to count up the frequency of occurrence of
Main cause additional information processing means 4 uses the failure part information of the misjudgment.
Notify.

Note that the weighting B3 in which the failure occurrence information E1 of the main cause determination file 6 corresponds to the failure part F2 is defined in advance by the maintenance person.

As described in detail, according to the present invention, the occurrence frequency corresponding to the failure part is stored in the main cause determination file, and the main cause additional information means updates the occurrence frequency each time the main cause determination is performed. Displaying the results of the cause determination logical means and instructing the operator as to whether the determination results are good or bad, and also notifying the main cause additional information processing means of the contents of the operator's instructions in order to reflect the operator's instruction results in the frequency of occurrence. Since it has a result user interface means, when a plurality of main cause determination results are determined, the operator can give an instruction to increase the accuracy of the next main cause determination.
