Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention displays drawing data such as equipment drawings on a CRT of a workstation, and
The present invention relates to a drawing display update device for updating the drawing data based on the display contents updated on the CRT.

[0002]

2. Description of the Related Art FIG. 7 shows, for example, <(case number AP-AM
540 is a block diagram showing a schematic configuration of a conventional drawing display updating device shown in “Application No. or Publication No. 540 >>“ Drawing Display Device ”. In the drawing, 1 is a server, 2 is a drawing database of the server 1, 3 is a LAN network for connecting the server 1 and the workstation 4, 5 is a CRT for drawing display provided in the workstation 4, and 6 is This is a work area that stores temporary data for drawing display.

Next, the operation will be described.

First, drawing data having a mesh number (mesh No.) required for display is transferred from the drawing database 2 of the server 1 shown in FIG. 7 to the work area 6 of the workstation 4 via the LAN network 3. Transfer and display on CRT5. Further, when the drawing is updated on the workstation 4, the data necessary for the update is stored in the work area 6, and the updated data is reflected in the drawing database 2 by the registration instruction of the change and registered.

[0005]

Since the conventional drawing display updating apparatus is constructed as described above, when the drawing data is updated on the workstation 4, the updated data is stored until it is registered in the drawing database. It exists on area 6. Infinite scrolling in this state,
Since new display data is overwritten on the work area 6 from the drawing database 2 of the server 1, the work area 6
The above update data will be destroyed. As a result, there is a problem that the CRT screen of the workstation 4 cannot be infinitely scrolled while the drawing data is updated on the workstation 4. Therefore, there is a problem that such a problem must be solved.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a drawing display update device capable of infinite scrolling while updating drawing data on a workstation.

[0007]

A drawing display update device according to the present invention is a server provided with a drawing database for storing drawing data, and an update data work for storing drawing update data in addition to a normal drawing display work area. When a drawing is displayed on a workstation having an area and a CRT provided in the workstation, the data transferred from the drawing database to the drawing display work area of the workstation and the update data The drawing update data in the work area And a means for synthesizing and displaying on a CRT.

Also, a server having a drawing database for accumulating drawing data and a workstation having a drawing display work area for temporarily storing drawing data and a CRT for display are connected by a communication path. The server is configured so that necessary portions of the drawing data stored in the drawing database can be transferred to a drawing display work area in a workstation via a communication path at any time. The database is configured so that drawing data can be identified by mesh numbers.

On the other hand, the workstation stores means for updating drawing data, an update data work area for temporarily storing drawing updated data, and a drawing display work area for storing mesh numbers required for display. CRT stored in drawing data and update data work area
Means for synthesizing drawing update data corresponding to the mesh number of the display portion to display the drawing on the CRT of the workstation, and means for updating and registering the drawing update data in the drawing database of the server according to the registration instruction input to the workstation. And updates the display screen displayed on the workstation by transferring the necessary part of the drawing data stored in the drawing database to the drawing display work area in the workstation via the communication path at any time. However, it is formed so that it can be scrolled infinitely.

[0010]

The drawing display updating device according to the present invention stores the drawing data transferred from the drawing database in the drawing display work area for temporarily storing the drawing data for drawing display, and, if necessary, the drawing data on the CRT. Are updated as appropriate and the updated drawing data is stored in the update data work area. By combining the data stored in the two work areas and displaying them on the CRT, infinite scrolling can be easily performed while updating the drawing.

[0011]

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention and a table showing the stored contents stored in each storage area. 11 is a server, and 12 is provided in the server 11. Drawing database, 13 is a LAN network, 14 is a workstation, 15 is a CRT for displaying drawings provided in the workstation 14,
Reference numeral 16 is a drawing display work area for storing temporary data for drawing display, and 17 is an update data work area for storing the updated portion of the drawing data updated on the workstation 14.

Reference numeral 20 is an example of the contents of the drawing database 12 in the server 11, and each data is recorded in the order of mesh number, drawing data, and coordinates. Similarly,
21 is data content of the drawing display work area 16;
Is the display content of the CRT 15, and 40 is the data content of the update data work area 17 recorded in the order of update type, mesh number, drawing data, and coordinates.

Next, the operation of this embodiment will be described.

In FIG. 1, mesh numbers 34, 35, 36, 44, 45, 46, 54, 55, 56 on the map shown in FIG. 6 are displayed on the workstation 14 as a drawing. From the contents of the drawing database 12, mesh numbers 34, 35, 36,
Items 44, 45, 46, 54, 55, 56 are extracted and transferred to the drawing display work area 16 of the workstation 14 via the LAN network 13, and based on the transferred drawing data contents 21, the CRT 15 A display such as display 30 is provided above.

Next, on the workstation 14, the drawing data E of mesh number 44 is moved to the left, and mesh number 45
When the drawing data “O” is added to, the updated data is displayed in the update data work area 17 as shown in the chart 41 of FIG.
It is stored as the update type, the mesh number, the drawing data and the coordinates as described above. The display is obtained by synthesizing the content 21 of the drawing display work area 16 and the chart 41 of FIG. 5 which is the content of the update data work area 17, and the mesh numbers are 34, 35, 36, 44, 45, 46. , 54, 55, 56 data are displayed on the CRT 15. The display contents on the CRT at this time are in the state shown in the display 31 of FIG.

Here, by scrolling the display drawing, the display meshes have mesh numbers 35, 36, 37, 45, 46, 47, 55,
Change to 56, 57. The data of mesh numbers 37, 47, 57 are transferred from the contents 20 of the drawing database 12 to the drawing display work area 16, and the data of mesh numbers 34, 44, 54 in the drawing display work area 16 are deleted. Therefore, the contents 21 of the drawing display work area 16 are
Changes to the contents of the chart 22 shown in FIG. Also, CR
As the display on T15, the work area for drawing display 16
Of the contents of the chart 22 of FIG. 4 which is the contents of FIG. 4 and the contents of the chart 41 of FIG. 5 which is the contents of the update data work area 17, the mesh numbers are 35, 36, 37, 45, 46, 47, 55, 56,
The combined data of 57 are displayed. The display contents at this time are as shown in the display 32 of FIG.

As described above, the workstation 1
It is possible to scroll the display area indefinitely while sequentially storing the data updated on 4 in the update data work area 17.

At the time of instructing to register the updated data on the workstation 14, the diagram 41 of FIG. 5 which is the contents of the update data work area 17 is reflected in the drawing database 12, and the contents are shown in FIG. It is changed from the chart 20 to the chart 23 shown in FIG.

[0020]

As described above, according to the present invention, the drawing update data on the workstation is stored in the update data work area different from the drawing display work area. It is possible to scroll the drawing infinitely while updating, and it is possible to update the drawing display with extremely high work efficiency.
