[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network diagram management system, and more particularly, to a network management system that includes a plurality of terminal devices and a plurality of central processing units and performs monitoring and control based on network diagram information on a screen.

[0002]

2. Description of the Related Art Conventionally, in this type of network management system, information on a network to be managed is defined in advance as a network diagram, and the network diagram information is used for monitoring and controlling.

For example, as shown in FIG. 9, in a configuration in which a plurality of terminal devices 8a to 8c are connected to a processing unit 7, when any of the plurality of terminal devices 8a to 8c is changed, In order to make the network diagrams of the terminal devices 8a to 8c identical, there is a method of individually changing the network diagram in each of the terminal devices 8a to 8c.

When a change occurs in the terminal device 8a,
The network diagram is changed only in the changed terminal device 8a, the data is stored in a storage medium such as a floppy disk, and the other terminal devices 8b and 8c read the data stored in the storage medium to read the network diagram. There are ways to make changes.

Further, when a change occurs in the terminal device 8a, the network diagram is changed only in the changed terminal device 8a, the data is transferred to the processing unit 7, and the data is transferred to the processing unit 7.
There is also a method of transferring the data from the other terminal devices 8b and 8c.

When the network diagram after the change is transferred via the processing unit 7, as shown in FIG. 8, the terminal device 6k (k
= A, b,...) Are collected in the central processing unit 5 at regular intervals via the remote control unit 62k of the terminal device 6k and the terminal processing unit 51k of the central processing unit 5. is there.

The central processing unit 5 combines the network diagram information collected at regular intervals via the remote control unit 62k and the terminal processing unit 51k, accumulates the network diagram information in the network diagram file 52, and stores the synthesized network diagram stored in the network diagram file 52. The figure data is distributed to the display processing unit 61k of the terminal device 6k, and is displayed on the terminal device 6k by the display processing unit 61k. As a technique for distributing image data such as composite network diagram data, Japanese Patent Laid-Open No.
There is a technique disclosed in Japanese Patent Publication No. 7-No.

[0008]

In the above-described conventional network management system, when a change occurs in any of a plurality of terminal devices, the network diagram is individually changed in each terminal device and all the terminal devices are changed.
