Abstract

PURPOSE:To immediately detect a fault occurring to a user side in automatic operation and to make a recovery from the fault, by equipping a maintenance center with a status information gathering and round checking means for user computers, a storage device, and an analyzing and diagnosing means. CONSTITUTION:A round checking means 1 makes an automatic circuit connection with user sides and starts an inquiry. On a user side, a status monitoring device SVP21 is actuated to check system conditions, and the result is transferred to the center side. The means 1 receives it and holds an inquiry to a next user system 20 when the received information shows that no fault occurs. When activity information is transferred, on the other hand, logging to the logging storage part of a record file 32 is performed and a diagnosing means 2 is actuated. The means 2 refers to the cause of a fault in logging information and a maintenance item table 33 to bracket the fault by inquiry items of an inquiry table 31, thereby informing the user side with the maintenance points. The user side performs maintenance operation and restarts the SVP21 to transfer its conditions.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote maintenance system, and particularly relates to a remote maintenance method, in which 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 a remote maintenance system is connected to the center computer system via the line. This invention relates to a remote maintenance method that patrols the next user's computer system and deals with the occurrence of failures.

Conventionally, a central computer system installed at a maintenance center and a user computer system installed at a remote location were always on standby, and 1) they were activated only when a failure occurred in the user computer system.

When a failure occurs in a user computer system, the user's resident maintenance personnel or user operator calls the maintenance center and the center manually connects the line to the contacted user, or the user's computer system The center computer system had been in operation since the failure occurred in the user computer system, and the line connection was made through two-way operation. When the line is connected, the user computer system activates a status monitoring device (hereinafter referred to as 8VP) to log system status information and transfer it to the center computer system. On the other hand, the center side used the transferred logging information to launch a predetermined diagnostic program to determine the cause of the abnormality and notify it to the computer system.

In the operation of computer systems, the problem arises that due to the absence of an operator, failures cannot be dealt with immediately and the reliability of the system cannot be guaranteed. K when a failure occurs in the user computer system inside.

The configuration is a medical examination I! equipped with a condition monitoring device. frJA
A diagnostic processing device having a plurality of diagnostic processing devices connected to each other, comprising: a circulating means for collecting status information and status information of the processing device to be diagnosed, a storage device for storing the collected status information, and a storage device for storing the stored status information. and a diagnostic means for analyzing, the nuclear patrol means makes rounds of the devices to be diagnosed in a predetermined order, stores the state information collected by the state monitoring device in the storage device, and then
The OJ% normal condition axis information of the processing device to be diagnosed is divided by the diagnostic means and notified to the condition monitoring device, and the details will be explained below using the diagram.

FIG. 1 is a device connection diagram according to an embodiment of the present invention. In the figure, 10 is a diagnostic processing device installed at the center, 11° is a storage device, 20 is a diagnostic processing device installed at the user side, and 21 is a state The monitoring device 15 is a line. FIG. 2 is a functional block diagram of the diagnostic processing device 10 in FIG. 1, in which S1 is a visiting means, 2 is a diagnostic record file, and 33 is a maintenance item table in which maintenance items are recorded. Figure 3 is a flowchart,
In the same figure (al is a work summary flowchart of the rounds examination means 1 in FIG. 2, and in the same figure (bl is a work summary flowchart of the diagnostic means 2 in FIG. 2).

The following description 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 in an unconventional scale means and the rounds means 1 are activated. For example, the interview table 31 includes user names, user names, etc.
There are entry items (not shown) such as dial number 1 interview item, 4-guing type item, and file name. The rounds means 1 establishes an automatic line connection (according to the prior art) with the user system 20 based on the written interview schedule (not shown) K in the interview table 31 and starts the interview. In the user preference system 20 that has received the interview, the status monitoring device 21 (hereinafter referred to as SvP) is activated and the user preference system 20 is started.
The system status of the system 21 is investigated, and if there is an abnormality in the system, operational information is collected and transferred to the center system 1G via the line IS. Also, if there is no problem with the system,
The 0th visit means 1, which transfers only the signal indicating no abnormality to the center system, receives the transferred information or signal, and when the signal indicates no abnormality, the user system 20 (D) records the completion of the medical interview. The next scheduled inquiry is made for the user system 20. On the other hand, when the operating information is transferred, the logging storage section (not shown) K of the record file 32 is sent.
I: I-gging and start diagnostic means 2 (
Press 0 and fill in the interview items listed in the interview table 31 (not shown).
Isolate the failure separately and connect the user system 20
Notify maintenance instructions to. 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 5vp2t again, checks the failure recovery status, and sends a recovery signal if the failure has been recovered, and operation information if the failure has not been recovered. Collect center system 10
・According to this embodiment, the nine user computers connected to the computer system can be regularly diagnosed and can prevent the occurrence of failures.60 Other embodiments of the present invention By cataloging the maintenance item table and 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, 8VP collects information only when a failure occurs, and when the rounding means detects information transfer, it is cataloged within the center and records the nine-tooth mosquito maintenance item table and diagnostic means in the inquiry table 31. The information is searched for using the interview items (not shown) and transferred to the user. According to this other embodiment, the development and maintenance of the diagnostic means is facilitated by converting the Seta Seven FiiK into four formats.

According to the present invention, there is an effect of eliminating failures in the user computer system.
