DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a plant screen design support apparatus for designing a plant screen in a system for monitoring and controlling plant equipment.

[0002]

2. Description of the Related Art As a conventional plant screen design support apparatus, for example, an apparatus shown in FIG. 9 has been proposed. In this conventional example, a CAD system 52 for creating a plant screen and a table editor 53 for creating a specification table of a plant screen are separately provided in a plant screen support tool 51.
The plant screen information created by the AD system 52 and the specification table information created by the table editor 53 are stored in the relational database 54 in association with each other.

Here, the CAD system 52 reads plant screen information of a predetermined unit from the relational database 54 at the time of startup, writes the changed plant screen information at the time of storage after editing data, and writes the plant screen information to the relational database 54. In the table editor 53,
The configuration is such that the specification table information of a predetermined unit is read from the relational database 54 at the time of startup, and the specification table information changed at the time of storage after editing the data is written into the relational database 4.

[0004]

However, in the above-described conventional plant screen design support apparatus, when defining moving picture data in which a design (characters, colors, sizes, graphs, etc.) changes according to a state used on the plant screen, , CAD
This can be performed from either the system 52 or the table editor 53. Since this moving image data is centrally managed by the relational database 54, the moving image data is
Even if one of the AD system 52 and the table editor 53 is updated, this update can be reflected in the moving image data viewed from the other.
The degree of change of the moving image data updated by the CAD system 52
In the case of confirmation, it is necessary to first write the specification table information updated by the table editor 53 in the relational database 54 and store it, and then close the table editor 53 before starting the CAD system. There is an unsolved problem that checking data on the other side requires a lot of time and effort.

[0005] In particular, the read / write processing of the relational database 54 by the CAD system 52 and the table editor 53 becomes extremely slow due to connection to the relational database 54, collision of input / output interfaces, use of a network, and the like. There is a problem that the confirmation work cannot be easily performed. Therefore, the present invention has been made by focusing on the unsolved problem of the conventional example described above, and the screen forming means and the table forming means are directly linked with each other without through a relational database to update the moving image data in two steps. It is an object of the present invention to provide a plant screen design support device which can be easily confirmed between two means.

At least an AD software and a table editor for creating a specification table are stored, and the arithmetic processing device 1a is connected to the relational database 3 via the communication control device 4.

Further, the relational database 3 stores plant drawing information created by CAD software and specification table information created by a table editor in association with each other, and includes symbols (characters, colors, sizes, graphs, etc.). The moving image data in which the) changes is assigned a unique identification code, for example, a POS number.
When updated by either the AD software or the table editor, the update result is centrally managed so that the updated result is reflected on the other.

The computer 1 executes a management process shown in FIG. In this management process, first, in step S1, the relational database 3 is searched to display a list screen representing information such as stored plant screens and specifications, and then the process proceeds to step S2 to display, edit, It is determined whether or not a processing menu such as printing has been selected, and if these have not been selected, the process proceeds to step S3 to determine whether or not an end menu has been selected. Finish the process as it is,
If the end menu has not been selected, the process returns to step S2.

On the other hand, if the result of the determination in step S2 is that the processing menu has been selected, the flow proceeds to step S4, where it is determined whether or not one or more pieces of desired information have been selected from the list screen. If not, the process waits until it is selected, and if it is selected, the process proceeds to step S5, where a CAD, a table editor, etc., for performing a plant screen forming process for processing one or more pieces of selected information, a specification table forming process, etc. After starting the application software, the process proceeds to step S6, and in a plant screen forming process or a specification table forming process described below, whether a “link” or “CAD link” pull-down menu displayed on the display screen is selected. When the pull-down menu of “link” or “CAD cooperation” is not selected, the process proceeds to step S8, When the pull-down menu of links "or" CAD cooperation "is selected, step S
The process proceeds to step S8, where link processing is performed in accordance with the function selected in the selected pull-down menu, and then the process proceeds to step S8.

In the link processing in step S7, when "link" is selected from the pull-down menu, moving picture data in which the design (characters, colors, sizes, graphs, etc.) are changed between the plant screen forming processing and the specification table forming processing. If it is determined that there is a link, and there is video data having an identification code corresponding to the identification code of the processing side that has designated “link”, specify the relevant video data.If there is no corresponding video data, , A message to specify the video data is displayed, and when the video data is specified, a link is established so that the corresponding video data can be exchanged between the corresponding video data, and the specification of the video data to be linked is completed. When "link complete" is selected, indicating that the link has been established, the link establishment process is terminated, and when "link confirmation" is selected, the specified video data is It indicates whether a link has been established, and ends the link confirmation process further "link confirmation end" is selected, to release the link established at the time by selecting the "Unlink".

In step S8, the aforementioned step S3
It is determined whether or not the end menu has been selected in the same manner as described above. If the end menu has been selected, the process is terminated as it is. If the end menu has not been selected, the process returns to step S6. Further, the computer 1 executes a plant screen forming process shown in FIG. 3 corresponding to the plant screen forming means. In this plant screen forming process, first, in step S11, the selected plant screen information is fetched from the relational database 3, and then, in step S1
The process proceeds to 2 to perform a plant screen update process. This plant screen updating process uses existing line data such as a line type representing a line type, a line color representing a line color, and a graphic type selection menu for selecting a graphic such as a straight line, a circle, or a square. It performs processing such as changing, drawing a new shape linework to create still image information, and upgrading the created still image information to moving image data. A POS number is assigned.

Next, the process proceeds to step S13, where it is determined whether or not "reflect" is selected from the "link" pull-down menu.
The process proceeds to 14 to determine whether a link has been established. If the link has not been established, the process proceeds to step S1.
5, the process returns to step S14 after outputting a message prompting the user to establish a link. When the link is established, the process proceeds to step S16, where updated moving image data is extracted. After writing the data and the identification code in the shared memory CM as a work area formed in the storage device 1c, the process proceeds to step S17, and “reflect”
If is not selected, the process proceeds directly to step S17.

In this step S17, it is determined whether or not "capture" is selected from the "link" pull-down menu. If "capture" is selected, step S18 is performed.
To determine whether the link is established,
If the link has not been established, the process proceeds to step S19, a message prompting the user to establish the link is output, and the process returns to step S18. If the link has been established, the process proceeds to step S20, and the process proceeds to step S20. The stored updated moving image data and identification code are read, and a predetermined conversion process is performed as necessary, and then the corresponding moving image data is updated.

If the result of the determination in step S17 is that "capture" has not been selected, the flow shifts to step S21 to determine whether "storage" has been selected from the "file" pull-down menu. When "save" is selected, the process proceeds to step S22, the updated plant drawing information is overwritten on the relational database 3, and then the plant screen forming process is terminated. When "save" is not selected, Step S12
Return to

Further, the computer 1 executes a specification table forming process shown in FIG. 4 as a table generating means. In the specification table forming process, first, the specification table information selected in step S31 is fetched from the relational database 3, and then the process proceeds to step S32 to perform a specification table update process. In the specification table updating process, a process of inputting characters into each item of the displayed usage table or inputting data designating characters, colors, sizes, and the like of moving image data using the keyboard 1e is performed. The same POS number is assigned to the moving image data corresponding to the moving image data in the screen forming process when the moving image data is defined.

Next, the process proceeds to step S33, where "C
It is determined whether or not "reflection" is selected from the pull-down menu of "AD cooperation". If this is selected, the process proceeds to step S34 to determine whether or not a link is established, and the link is not established. At this time, the process proceeds to step S35 to output a message prompting to establish a link, and then returns to step S34. If the link is established, the process proceeds to step S36 to extract updated moving image data. After the moving image data and the identification code are written in the shared memory CM as a work area formed in the storage device 1c, the process proceeds to step S37. If "reflect" is not selected, the process directly proceeds to step S37.

In step S37, "CAD cooperation"
Is determined from the pull-down menu of “No.”, and if “Capture” is selected, step S
38, it is determined whether or not the link has been established. If the link has not been established, the process proceeds to step S39.
And outputs a message prompting the user to establish a link, and then returns to step S38. If the link is established, the process returns to step S40 to return to shared memory C
The updated moving image data and the identification code stored in M are read, a predetermined conversion process is performed as necessary, and the corresponding moving image data is updated.

If the result of the determination in step S37 is that "import" has not been selected, the flow shifts to step S41 to determine whether "save" has been selected from the "file" pull-down menu. When "save" is selected, the process proceeds to step S42, the updated plant drawing information is overwritten on the relational database 3, and then the plant screen forming process is terminated. When "save" is not selected, Step S32
Return to

Then, in the processing of FIGS. 2 to 4 described above, steps S6, S7, S13 to S20 and S33 to
The processing in S40 and the shared memory CM constitute a data linking unit. Next, the operation of the above embodiment will be described.
Now, it is assumed that the relational database 3 stores plant screen information and specification table information each including moving image data created in advance.

When the computer 1 is started in this state, the management processing shown in FIG. 2 is started, and the titles of various information stored in the relational database 3 shown in FIG. 5 are displayed in a list. In this state, a description will be given of a case where the moving image data defined in both of them is changed using, for example, plant screen information and function-specific specification information.
By clicking on the “plant screen” of “No.” and the “specification by function” of section number 2.3, the CAD software and the application software of the table editor corresponding to these are started, and FIG. 3 and FIG. The execution of the plant drawing forming process and the specification table forming process shown in FIG.

For this reason, as shown in FIG. 6A, plant screen information including moving picture data and specification table information are fetched from the relational database 3 and are displayed on the display 1.
As shown in FIG. 7, on the display screen g, either one of the plant screen creation screen 11 and the function-specific specification table creation screen 12 which are simultaneously or activated in different windows are displayed.

In this state, for example, the function-specific specification table creation screen 12 is activated, and as shown in FIG. 6B, for example, the character string "Ai" is changed to "POS" in the specification data of the POS number "0001". After the display color is updated from "red (R)" to "green (G)" using the keyboard 1e, the "CAD cooperation" displayed at the upper left in FIG.
Is selected from the pull-down menu 21, a link is established to the moving image data of the POS number "0001" in the plant screen forming process that has been started up at the same time.

In this state, when “reflection” is selected from the pull-down menu 21 of “CAD cooperation” on the function-specific specification table creation screen 12 in FIG. 7, as shown in FIG.
The S number “0001”, the changed character string “ABC” and the display color “green” are used as the updated moving image data in the shared memory CM.
Is written to. In this state, the plant screen creation screen 11
Is activated, and as shown in FIG. 7, by selecting “capture” from the “link” pull-down menu 20, as shown in FIG. 6 (d), the update stored in the shared memory CM is performed. The moving image data is read, and the moving image data with the matching POS number is updated. For this reason, the moving image data displayed together with the POS number 22 on the plant screen creating screen 11 is immediately changed to “ABC”, and the updated state of the moving image data can be easily and reliably visually recognized.

Then, on the activated plant screen creation screen 11, select “unlink” from the “link” pull-down menu 20 or use the usage table creation screen 12.
Activate the “CAD Link” pull-down menu 2
By selecting “unlink” from 1, the link state of the moving image data can be cut off, and individual processing can be performed in the plant screen formation processing and the usage table formation processing.

When the user wants to know the current link status on the specification table creation screen side, the user can select “link confirmation” from the “CAD linkage” pull-down menu 21 to display the current link status by blinking display, for example. The link confirmation state can be ended by selecting "end of link confirmation".

After that, to end the moving image data updating process, the "file"
By selecting "Save" from the pull-down menu 22, the updated plant screen information is overwritten on the relational database 3, and "Register" is selected from the "DB registration" pull-down menu on the specification table creation screen 12 in FIG. Is selected, the updated specification table information is overwritten on the relational database 3, and then returns to the display state of FIG. 5. In this state, for example, by selecting "End" from the "Display" pull-down menu, , All the processes can be ended.

When the moving image data is updated from the plant screen creating screen 11, for example, change of display color, character, etc. is selected from the "edit" pull-down menu, and moving image data of a desired POS number is designated. , After updating the video data, select “Reflect” from the “Link” pull-down menu.
Is selected, the POS number and the updated moving image data are written to the shared memory CM. In this state, the specification table creation screen is activated, and "Import" is selected from the "CAD cooperation" pull-down menu 21. As a result, the POS number and the updated moving image data stored in the shared memory CM are read, and the moving image data in the specification table is updated.

Further, when the creation of the plant screen and the specification table is completed, the plant screen information and the specification table information are both output to the printer 1h for printing. The color-printed plant screen can represent an image closer to the actual machine, but can read detailed data such as moving image data from the data shown in the specification table even in monochrome printing.

As described above, according to the above embodiment, as shown schematically in FIG. 8, the data link between the plant screen formation processing unit 31 and the specification table formation processing unit 32 is linked to the link function 33 of the management processing unit. Because it is managed by
When the moving image data is updated in the specification table formation processing, the data can be directly linked via the shared memory CM without passing through the relational database 3, and the confirmation when the moving image data is updated is easily and quickly performed. be able to.

Incidentally, in the conventional example, the plant screen information and the specification table information are fetched from the relational database 3 at the time of startup in the plant screen formation processing and the specification table formation processing. When the moving image data is updated, first, the specification table forming processing side performs “storage” processing and stores it in the relational database 3. In this state, by starting the plant screen forming processing, the processing is stored in the relational database 3. By acquiring plant screen information including updated moving image data, updated moving image data will be displayed for the first time, and the confirmation work is complicated, time-consuming, and time-consuming for moving image data on the plant screen. Update work cannot be done easily and quickly In the present invention, as described above, by providing the data linkage means, it is possible to perform the updating of the moving image data easily quickly.

In the above embodiment, the case where the selection of the link function or the like is selected from the pull-down menu has been described. However, the present invention is not limited to this, and these functions are assigned to the function keys of the keyboard 1e. , May be selected by key input. Further, in the above embodiment, the case where the computer 1 and the relational database 3 are connected one-to-one has been described. However, the present invention is not limited to this, and a plurality of computers may be connected to the relational database 3 via the network 2. May be connected, and the relational database 3 may be accessed from these.

Further, in the above embodiment, the case where the computer 1 and the relational database 3 are connected via a network has been described.
The present invention is not limited to this, and the relational database 3 may be constructed in one computer. Furthermore, in the above embodiment, the case where the titles of the pull-down menus 20 and 21 for selecting the link function are different has been described. However, the present invention is not limited to this, and the plant screen creation screen 11 and the specification table creation screen 12
It goes without saying that a unified title may be used.
