DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for constructing a large-scale information network and a network management system for managing a network between the devices, and a network configuration for visually managing the configuration information of the management device by a network configuration diagram. The present invention relates to an automatic drawing creation device.

[0002]

2. Description of the Related Art Conventionally, when a network configuration diagram is displayed on a monitor screen so that the configuration of devices to be managed in the network management system and the connection relationship between the devices can be easily understood visually, it is fixed for each device to be displayed. The screen of the network configuration diagram is created by registering the coordinate data, determining the display position, and registering the information of the line indicating the connection relationship.
Therefore, the screen information of the network configuration diagram is provided independently of the configuration information such as the connection route between the devices that is held as the management information. That is, screen information is defined for all devices, and the screen information is updated when the connection relationship between devices is changed or the number of connected devices is added or deleted.

[0003]

In the above-mentioned prior art,
Since the configuration information such as the connection path of the device is created in accordance with the processing of the control system, it is difficult to create it by incorporating the screen information, and the registration of the screen information is a separate task. Therefore, when managing a large-scale information network, it is necessary to define screen information of a huge number of managed devices, which requires a great number of man-hours.

Further, if the screen information is fixedly held, the screen information must be changed at any time in response to changes in network configuration information such as increase / reduction of connected devices or change of connection relation between devices. There is a point.

[0005]

Means for Solving the Problems An automatic network configuration diagram creation device of the present invention is a screen pattern table in which attribute information of each device necessary for creating a network structure diagram is registered as a screen pattern, and a device name via which the device is routed. Of a network structure diagram from a configuration information table defining configuration information including route information in which connection sequences are arranged in the order of connection, the configuration information defined in the configuration information table, and the screen pattern registered in the screen pattern table. A node table registration means for creating attribute information of each node necessary for creation, a node table for storing the attribute information of each node, and a screen creating means for creating a network configuration diagram based on the node table ing.

[0006]

The type of the connection route of the device to be managed that configures the network is patterned and registered as a screen pattern for each connection route pattern, thereby creating the node table together with the configuration information and based on this. Automatically creates a network configuration diagram.

By doing so, even if the connection paths between the devices are similar, it is not necessary to create a configuration diagram individually, and there is no change in the connection path such as addition or removal of devices connected to a certain device. The configuration diagram is automatically changed in response to the change of No., so that it is not necessary to re-register the configuration diagram each time.

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

FIG. 1 is a block diagram of the present invention.
The automatic network configuration diagram creation apparatus of the present invention is included in the network management system 1, and registers the screen pattern registration means 11 for registering the screen pattern of each device to be managed that constitutes the network, and the information of this screen pattern. Screen pattern table 14 to be stored and configuration information registration means 12 for registering configuration information including network route information.
And the configuration information table 15 in which this configuration information is registered
And a node table registration means 13 for registering node information of each device to be managed that constitutes a network from screen pattern information and configuration information, a node table 16 for storing this node information, a screen pattern table 14 and a node. A screen configuration means 10 for automatically creating a network configuration diagram based on the table 16 and displaying it on the terminal device 2.

The network management system 1 is connected to the network by a communication line 3 and has a terminal device 2 for managing the network and displaying a status.

FIG. 2 shows a concrete example of the screen pattern table 14.

The screen pattern table 14 is provided with attribute information (color, coordinate position, how to draw a connection line with a higher-level connection device, graphic parts, installation position of a name) necessary for drawing each device displayed on the network configuration diagram. Etc.) is defined for each device type,
Register for each connection route pattern.

The screen pattern table 14 of FIG. 2 will be described in detail with reference to FIGS. 3 and 4.

FIG. 3 shows the respective route information of the area α and the area β as a specific example of the configuration information defining the connection relation of the devices managed by the network management system 1. In the routes that compose the network, the names of the devices that have passed through are arranged in the order of connection, and only one end device is defined as one route, and the device type is defined for each device name. This device type is a key item when referring to the screen pattern.

For example, in FIG. 3, a, b, c, and
The four routes of d are set, and the route a has a node name xx01 having a device of device type A as a node, a node of device type B and node name yy01, and a device type E of node name It is shown that the node of qq01 is connected from the higher order to the lower order.

FIG. 4 is an image diagram of a network configuration diagram created based on the route information of the areas α and β of FIG. 3 and the definition information of the screen pattern table 14.

Correspondence between the network configuration diagram of the area α in FIG. 4 and the screen pattern table 14 in FIG. 2 will be described.

The nodes xx01 and xx02 located at the top of the area α network in FIG. 4 correspond to the node nos 01 and 02 having the area type A in FIG. 2, respectively. Even though the device types are the same, they are different nodes, so they are distinguished by the node no. The coordinates are (a
1, b1) and (a2, b1) have different x coordinates and common y coordinates. The connection line connects the node in question and the node above it. Therefore, the node xx01 is also xx
Since 02 is also a higher level, the connection line is registered as "none". Both figures are represented by black circles. In the next field, a pointer indicating the next node of the same type when a plurality of nodes of the same device type exist is stored. The priority order (a, b) indicates a sequence order number in the same area (in the same y coordinate) when a is the highest node, and 0 in cases other than the higher order. b shows the serial number of a node in the same area (within the same y coordinate) under the control of the same node. Since the nodes xx01 and xx02 are arranged in the same y-coordinate in order from the left, the priority order a is 1 and 2, respectively. Since there are no multiple nodes in the same y-coordinate, the priority order b.
Are both 0. Nodes yy01 and yy02 in FIG. 4 correspond to the device types B and C in FIG.
The coordinates are (a2, b2) and (a3, b2), and the connection lines are displayed so as to be connected to a plurality of upper nodes, and thus are registered as "plurality". The figures are represented by white and black squares, respectively. The priority is not the highest node, and since there are no multiple nodes in the same y coordinate, both are (0, 0). The node zz01 in FIG. 4 corresponds to the device type D in FIG. 2, the node no is 01, and the coordinates are (a
2, b3), and since the connection line is displayed so that only one line is connected to the upper node, it is registered as "single". The figure is represented by a black triangle, and the priority is not the highest node, and since there are no multiple nodes in the same y coordinate, both are (0, 0). Node qq0 in FIG.
1, qq02, qq03, and qq04 all correspond to the device type E in FIG. 2, and since there are many nodes of the same device type, the node no is 00 and the x coordinate cannot be specified (00, b4). , The connecting line is displayed so that only one line is connected to the upper node, so it is registered as "single". The figure is represented by a double circle, and the priority is both (0, 0) because it is not the highest node and there are no multiple nodes in the same y coordinate.

Similarly, the screen pattern of the area β can be associated with the definition of FIG. In other words, even if the network configuration diagram of two different areas, one screen pattern may be registered.

The device type in FIG. 2 is "dummy". This is because the screen creating means 10 cannot draw a plurality of connecting lines between the same nodes when there are a plurality of connecting lines. It is necessary to create multiple connection lines between the same nodes by creating connection lines between dummy nodes so that they can be displayed on the screen.

As described above, the screen patterns of the route information corresponding to the areas α and β shown in FIGS. 3 and 4 are registered in the form shown in FIG. In other words, if the screen pattern as shown in FIG. 2 is registered, the network configuration diagram having the route information shown in the areas α and β is automatically created as shown in FIG. 4 and displayed on the terminal device 2. .

FIG. 5 is a flow chart showing the flow of processing up to the creation of the network configuration diagram.

First, the screen creating means 10 accesses the composition information table 15 registered in advance by the composition information table registration means 12 to compose one path information of the composition information of the area to be displayed on the screen as shown in FIG. Importing the information table 15, the screen pattern of the screen pattern table 14 is searched from the head device in the connection order of one path using the device type as a key item, and the definition information of the device is acquired (step 5
-1 to 5-3).

In the following description, the case of the route information a in FIG. 3 will be described as an example.

The screen creating means 10 accesses the node table 16 via the node table registering means 13 and checks whether the acquired device type is already registered in the node table 16 (step 5-4). The node table 16 has registered therein information required when the screen creating means 10 creates a screen of the network configuration diagram.

If not registered, the contents of the acquired screen pattern (device type, node no, priority order,
Coordinates, connection lines, figures, etc., node names, upper nodes, and parent nodes are registered in the node table 16 (step 5-6).
~ 5-8).

First, the head node xx01 of the route information a is
Since the device type is A, the screen pattern of the screen pattern table 14 is searched using A as a key item, and if not registered, it is registered in the node table 16. In the case of the node xx01, the device type is A, the node no is 01, and the upper node (a node indicating a partner for drawing a connection line) is the node xx0.
Since 1 is the highest node, there is no setting. The parent node that is set only when a plurality of connection lines are set is also not set in this case (step 5-
9). Information on the screen pattern table 14 is registered for the priority order, coordinates, connecting lines, and figures. Node xx01
Is registered to the next node (in this case node yy0
1) is saved as an upper node (step 5-1)
0).

The nodes yy01 and qq01 are also registered in the same manner, and this is repeated sequentially for the routes b, c and d.

When registering the node yy01 in the node table 16, since there are a plurality of connecting lines, the connecting line information setting process (step 5-9) is required. That is, since it is necessary to draw a plurality of connecting lines with the upper node xx01, a dummy node that cannot be seen on the display is created for that purpose, and connecting lines are drawn between the dummy nodes (see the diagram in FIG. 7). (See the enlarged view of 4).

The connection line information setting process will be described in detail with reference to the flowchart of FIG.

First, a dummy node (for higher order) xx01dm of a partner node xx01 which draws a connecting line of the node yy01.
1 is created (step 7-1).

The dummy node is created as a child node of the parent node (xx01). The node name of the dummy node is
Duplication of names is prevented by setting in the format of "parent node name + dm + parent node serial number". For the coordinates of the dummy node, the coordinates of the parent node are inherited and set, and become the X coordinate start position in the rearrangement process described later, and the actual display position is reset by this process. The screen pattern of the dummy node is
The screen pattern table 14 is searched and acquired by the device type dummy.

A node of the device type whose screen pattern node no is 00, such as a dummy node, is used for a large number of devices of the same device type and it is not possible to register all the patterns by definition. One pattern is defined as a representative. By doing so, the coordinates are automatically calculated by the rearrangement process described in detail in FIG.

The priorities used in this relocation processing are such that the coordinates are calculated in the order of the highest node in the route in order to prevent the connecting lines from crossing and overlapping when rearranging a plurality of nodes.

Among the priorities (a, b), a indicates the order number (1 from the left) of the topmost node of the route in the same Y coordinate, and b is under the same topmost node. Shows the serial number of the node within the same Y coordinate. Therefore, for the node whose node no is 00, the same value as the priority a of the top node saved from the screen pattern is also set in the priority a of the dummy node, and its serial number is set to 1.
Just count up and set. That is, the priority of the dummy node xx01dm1 is (1,1). Similarly, a dummy node (for target) yy01dm1 is created, and an upper dummy node is set in the upper node in order to draw a plurality of connecting lines with the node xx01 (step 7-2).

When the registration of the path information a to the node table 16 up to the node qq01 is completed, the registration processing is similarly performed for the next path information b, c, d.

Here, in the case of the route information d, the node xx02
Since the node xx01 has already been registered as the node of the device type A when the node table 16 is searched, the next node is searched from this screen pattern. next
Since the record number linked to the next of the record of the screen pattern 0 is set, the t node searches for it as a key item and acquires the screen pattern information (step 5-5).

The above processing is repeated (step 5-1
5-10), when all the route information of the configuration information of the area to be finally displayed on the screen is loaded, the node table 1
6, the relocation processing is executed for the node whose node no is "00" (step 5-11), the screen is created by referring to the node table 16, and the network configuration diagram is displayed on the terminal device 2 (step 5-). 12).

The rearrangement process will be described in detail with reference to FIG.

First, in order to extract a node whose X coordinate is not specified and is 00, the node no which is 00 is extracted as a key (step 8-1).

FIG. 9 shows a concrete example of a work table for rearranging in the rearrangement process.

After extracting the node with node no 00, the same Y
Within the coordinates, within the same top-level a with the same priority (a, b), serial number b
The node table 16 is sorted in order (step 8-2).
"Node interval x serial number" with the X coordinate inside as the starting point
Is calculated, and the X coordinate of the node table 16 is updated (step 8-3).

FIG. 6 shows a state (A) before relocation and a state (B) after relocation of the node table 16. The coordinate setting has changed due to the relocation process.

After the rearrangement processing is completed, the screen creating means 10
Determines the display position of each node from the coordinates in the node table 16, displays the specified figure as the shape of the display, displays the node name as the name of the figure, and connects the nodes with the specified upper node. A network configuration diagram is automatically created by drawing with.

[0045]

As described above, according to the present invention, when the network configuration information and the screen pattern information are registered in advance, the screen information is not fixed but displayed on the terminal device. Since necessary information is edited and created and displayed, other than drastic network configuration changes such as addition of unregistered connection route patterns,
Basically, it is not necessary to change the screen information. As a result, the work of changing the registration information for displaying the network configuration information accompanying the change of the network configuration information is significantly reduced, and efficient operation becomes possible.
