Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a process according to an embodiment of the present invention.

[0010] The graphics are displayed by the client 3 on the server 2
This is done by reading graphic information from and displaying it on the display 14. A database 4 is provided in the server 2 and is rewritten by the related system / sensor 1 or the like.
The reception processing unit 9 in the client 3 receives the graphic information from the database 4 and stores it in the graphic buffer 10. The display processing unit 11 edits the graphic information in the graphic buffer 10 into a display code, and displays it on the display 14 as a graphic, a specification text, or the like.

When an integrated display request is received from the keyboard 12 or the mouse 13, the input processing unit 8 processes the integrated display request and passes it to the related graphic selection processing unit 7. The related graphic selection processing unit 7 selects a related graphic group from the designated range and the graphic information of the graphic buffer 10 and notifies the display position calculation processing unit 6 of the selection. The display position calculation processing unit 6 calculates the display position of the aggregated figure from the position information of the selected figure group, and notifies the figure data creation processing unit 5 of the calculated position. The calculation of the display position is based on finding the average of the display positions (X coordinate and Y coordinate) of each figure. The graphic data creation processing section 5 creates graphic data of the aggregated figure at the notified display position, and
Add to the figure information of. The display processing unit 11 performs deletion of related graphics, display of aggregate graphics, and the like according to the data in the graphics buffer 10.

A method of consolidating related graphic groups will be described with reference to FIGS. FIG. 2 shows a screen image diagram in the embodiment of the present invention. In FIG. 2A, a range indicated by a dotted line is designated by the mouse 13 or the like in the graphic before the aggregation.
From the group of figures within the designated range, a related figure selection processing unit 7
In, the related figure group is selected. From the position information of the selected graphic group, the display position calculation processing unit 6 calculates the center position of the related graphic group. From the calculation result, the graphic data creation processing unit 5 displays the aggregated graphic on the map as shown after the aggregation in FIG. If the position information is updated from the related system / sensor 1 etc., the reception processing unit 9 recognizes the update of the related graphic, notifies the display position calculation processing unit 6, and re-executes the display position calculation processing unit 6. Perform calculations and automatically update the display position.

FIG. 3 shows an example of a graphic format according to the embodiment of the present invention. As shown in FIG. 3A, the graphic format is roughly divided into three types of information: related information, single information, and aggregated information. The related information is information of a group of related graphics, and includes a plurality of pieces of individual information. The single information is information of a single figure that does not belong to any group. The aggregate information is information of an aggregate graphic for a group of related graphics designated to be aggregated. Each piece of information is represented in detail as shown in FIG.

IDNO represents a unique number assigned to each piece of information. The aggregate IDNO represents the IDNO of the aggregate information when the related graphic group is designated to be aggregated. The value is 0 when no aggregation is specified, or when the information is single information or the aggregation information itself. By determining this, the related graphic group is selected from the graphic group within the designated range. FRONT-related IDNO is the ID of the information that appeared immediately before that is included in the same related figure group
Indicates NO.

[0015] In the case of the first information of the related information or the single information, it is 0. The NEXT related IDNO indicates the IDNO of the next appearing information included in the same related graphic group. It is 0 in the case of the last information of the related information, or the single information or the aggregate information itself. By performing a chain search using the FRONT-related IDNO and the NEXT-related IDNO, related information leaked from the specified range can be included in the aggregation target without being left.

The name indicates the name of a figure or the like. In this embodiment, the name is displayed on the screen together with the figure as a text sentence. The symbol and position are the shape, color, and X for displaying the figure on the screen.
Represents the coordinates and the Y coordinate. The position of the integrated information is obtained by calculation from the position information of each piece of related information. This is a simple average value calculation, and when there are n related figures, X = ΣXi
/ N, Y = ΣYi / n (i = 1 to n). There is other information such as other specifications.

FIG. 4 shows a diagram in which information of an aggregated figure is displayed on an aggregated display screen. When the information display of the aggregated figure is specified, FRONT related ID in the aggregated information
Individual information is searched in order based on the NO, and the contents of each individual information are listed as specifications.

In the present embodiment, the specification is displayed. However, the processing contents allow the collective operation on the related information, and the collective deletion, the collective movement, the integrated display cancellation, and the like can be handled in the same manner.

[0019]

According to the present invention, it is possible to designate only a range to be displayed in an integrated manner, and to display an integrated graphic at an accurate center position of a group of related graphics, thereby making it easy to determine a situation.

Further, it becomes possible to collectively perform the processing on the related graphic group by the operation on the aggregated graphic, thereby improving the operability.
