Abstract

PROBLEM TO BE SOLVED: To reduce operation loads on a host side and on a terminal side relating to program maintenance by automatically comparing the management information of a host server and a terminal client when the power source of the terminal client starts supply and performing replacement with a latest volume corresponding to a latest program. SOLUTION: In the case of executing remote maintenance, by a maintenance information registration means 2, the remote maintenance management part 3 of the host server 1 updates version management information 4 and a program storage area 5 first. Then, when the power source of the terminal client 7 is fed, the remote maintenance management part 8 receives the version management information 4 of the host server 1 and executes the all matter comparison processing of the information and the version management information 9 of the terminal client 7. Then, the selection of a volume or a program requiring updating is executed and the remote maintenance management part 8 updates the version management information 9 and the program storage area 10 by the transferred volume or program.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote maintenance automation system, and more particularly to a system for keeping a program up-to-date even when there is no maintenance operation personnel on the terminal client side.

[0002]

2. Description of the Related Art In the conventional maintenance system, maintenance operation personnel exist on the terminal client side to perform maintenance, or as shown in FIG. 2, only the host computer has program management information so that remote maintenance can be performed. (For example, Japanese Patent Laid-Open No. 4-243428).

That is, the keyboard 21 displays a host connection request from the operator on the screen display unit 32 and informs the host connection control unit 23 of the terminal controller 31.
Here, a connection request is transmitted to the terminal connection control unit 26 in the host computer 32 through a line, and the terminal computer is connected to the host computer. When the connection request is completed, the remote software maintenance control unit 27 checks the software version in the corresponding terminal controller from the software management table storage unit 28, and if the version is not updated, the latest version of the software is stored in the terminal controller 31. To the software maintenance control unit 24 of
When the transmission is completed, the software version in the management table is updated to the latest version. Further, the software maintenance control section 24 in the terminal controller 31 can execute automatic remote software maintenance by writing the latest software from the remote software maintenance control section 24 in the host computer 32 into the software storage section 25. .

[0004]

In the conventional maintenance method, when the maintenance factor is present on the client side and the maintenance is performed, there is an operational problem that it is difficult to determine the timing of performing the maintenance. Further, even in the method in which the program management information is provided only in the host computer, the operation when adding a new program and this version management operation become complicated with only the version information for each program as the number and frequency of maintenance increase. It had operational problems.

[0005]

A first aspect of the remote maintenance automation device of the present invention comprises a host server having a communication means and a terminal client, and version management information in program units and volumes corresponding to a plurality of programs. It has a unit management information and each program storage area, and automatically compares the management information of the host server and the terminal client when the power supply of the terminal client is started, and the latest program or the latest program corresponding to multiple programs. It is configured with the function of replacing with the volume.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing a configuration of an embodiment of the present invention. A host server 1 comprises a remote maintenance management section 3, version management information 4 and a program storage area 5, and a maintenance information registration means 2 The version management information 4 and the program storage area 5 can be updated. Further, the terminal client 7 connected via the communication means 6 comprises a remote maintenance management unit 8, version management information 9 and a program storage area 10.

Next, the function of each section will be described in the order of operation. When performing remote maintenance, first, the remote maintenance management unit 3 updates the version management information 4 and the program storage area 5 in the host server 1 by the maintenance information registration unit 2.

When the power of the terminal client is turned on, the remote maintenance manager 8 receives the version management information 4 of the host server 1 via the communication means 6,
This information and version management information 9 of the terminal client 7
Executes the all comparison process with. The structure of the version management information is in the form of a table with volume IDs or program IDs and version number update dates, as shown in FIG.

Next, according to the processing flow shown in FIG. 3, a volume or program that needs to be updated is selected and a transfer request is made to the host server. The remote maintenance management unit 8 updates the version management information 9 and the program storage area 10 with the transferred volume or program. After that, control is passed to the normal terminal client startup processing, the latest program is loaded, and remote maintenance is completed.

The feature of the processing flow of FIG. 3 is that it has version management information related to the volume ID. When maintenance related to the volume is performed, all programs belonging to the volume are registered as maintenance information. One of the features of the present invention is that maintenance can be performed collectively without performing the maintenance.

[0012]

As described above, the present invention has the effect of significantly reducing the operational load on the host side and terminal side related to program maintenance in the system operation of the host server having the communication means and the terminal client.
