Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote maintenance method, in particular, a plurality of user computer systems installed in remote locations and a center computer system installed at a maintenance center are connected through a line, and the central computer system is connected to the center computer system via the line. This invention relates to a remote maintenance method that patrols user computer systems and deals with the occurrence of failures.

Conventionally, a maintenance method has been adopted in which a central computer system installed at a maintenance center and a user computer system installed at a remote location are connected via a communication line.

In conventional maintenance methods, the center computer system is always on standby and is activated only when a failure occurs in the user computer system. When a failure occurs in the user computer system,
Either the user's resident maintenance personnel or user operator maintenance center is notified by phone, and the center manually connects the line with the contacted user, or the user manually connects the line. Therefore, the center computer system had been operating since the failure occurred in the user computer system. When the line is connected, the user computer system uses a status monitoring device (hereinafter referred to as SVP)
, and logs system status information and transfers it to the center computer system. On the other hand, the center side uses the transferred logging information to determine the cause of the abnormality by running a predetermined diagnostic program and notifies the user computer system of the abnormality.

The remote maintenance method described above always requires human intervention on the user's side, and in recent unmanned computer system operations, it is not possible to immediately respond to failures due to the absence of an operator, leading to system reliability. A problem has arisen in which gender cannot be guaranteed.

In view of the above-mentioned problems, an object of the present invention is to solve the problem when a failure occurs in a user computer system during unmanned operation.
The present invention provides a maintenance method that can immediately detect and restore failures, and the configuration of the present invention to achieve this purpose is a diagnostic processing device in which a plurality of diagnostic processing devices equipped with a status monitoring device are connected. And,
It comprises a visiting means for making a status inquiry and collecting status information of the processing device to be diagnosed, a storage device for storing the collected status information, and a diagnosing means for analyzing the stored status information. After making rounds of the processing device to be diagnosed and storing the status information collected by the condition monitoring device in the storage device, abnormality information of the processing device to be diagnosed is isolated by the diagnostic means and notified to the condition monitoring device. The details are clarified using the diagram below.

FIG. 1 is a device connection diagram according to an embodiment of the present invention, in which 10 is a diagnostic processing device installed at a center;
1 is a storage device, 20 is a processing device to be diagnosed installed on the user side, 21 is a status monitoring device, and 15 is a line.
FIG. 2 is a functional block diagram of the diagnostic processing device 10 in FIG. 33 is a maintenance item table that records maintenance items. FIG. 3 is a flowchart, and FIG. 3a is a flowchart showing an outline of the work of the circulating means 1 shown in FIG. 2, and FIG. 3b is a flowchart showing an outline of the work of the diagnostic means 2 shown in FIG.

The following explanation will be made using both FIGS. 2 and 3. The diagnostic processing device 10 on the center side (hereinafter referred to as the center system), prior to the mobile diagnosis of the diagnosed processing device 20 on the user side (hereinafter referred to as the user system), records the users scheduled to be interviewed on the day in the interview table 31. The system 20 is described by a scheduling means (not shown), and the rounds means 1 are activated. The inquiry table 31 includes entry items (none of which are shown) such as a user name, user dial number, inquiry item, logging type item, and file name.
The rounds means 1 establishes an automatic line connection (based on the prior art) with the user system 20 based on the interview schedule (not shown) in the already filled interview table 31 and starts the interview. In the user system 20 that received the interview, the status monitoring device 21 (hereinafter referred to as SVP) is activated, investigates the system status of the user system 21, and if there is an abnormality in the system, collects operating information and disconnects the line. 15 to the center system 10. If there is no abnormality in the system, only the signal indicating no abnormality is transferred to the center system. The rounds means 1 receives the transferred information or signal, and when the signal indicates no abnormality, records the completion of the interview of the user system 20,
The next scheduled interview of the user system 20 is performed. On the other hand, when operating information is transferred, it is logged in a logging storage section (not shown) of the recording file 32, and the diagnostic means 22 is activated.

The diagnostic means 2 started by the rounds means 1 refers to the maintenance item table 33 to determine the cause of the abnormality in the logging information, isolates the failure according to the inquiry items (not shown) listed in the inquiry table 31, and determines the cause of the abnormality in the logging information by the user. The maintenance procedure is notified to the system 20. Note that, in the maintenance item table 33, for example, failure investigation items and maintenance procedures (none of which are shown) are cataloged and described for each device or device.

After performing maintenance work based on the notified maintenance instructions, the user system 20 starts up the SVP 21 again, checks the failure recovery status, and sends a recovery signal if the failure has been recovered, or operation information if the failure has not been recovered. are collected and transferred to the center system 10.

According to this embodiment, the user computers connected to the center computer system can be regularly diagnosed and can prevent the occurrence of failures.

As another embodiment of the present invention, by cataloging the maintenance item table and the diagnostic means, failure diagnosis can be performed on the user computer system side without depending on the center processing device. For example, in the user computer system, the SVP collects information only when a failure occurs, and when the rounding means detects information transfer, it transfers the maintenance item table and diagnostic means cataloged in the center to the inquiry table 31.
The information is searched for using the interview items (not shown) described in , and transferred to the user side. According to this other embodiment, there is an effect that maintenance can be performed on the user side without increasing the load on the center. Further, by cataloging and maintaining the maintenance item table and the diagnostic means at the center side, the development and maintenance of the diagnostic means is facilitated.

According to the present invention, there is an effect that fault diagnosis of a user computer system can be automated, and further there is an effect that fault prevention is possible and reliability of the computer system can be improved.
