Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention (Industrial Application Field) The present invention relates to a monitoring screen display device for displaying and monitoring plant status on a screen in various plants.

(Prior art) In recent years, in various plants, plans 1 to 2 have been expanded to larger sizes.
As equipment configurations become more complex, operators are required to monitor an increasingly large number of items. Therefore, in order to reduce the burden of monitoring work on operators and improve work efficiency, monitoring screen display devices that display plant status on a screen based on various preset monitoring screens and thereby perform plant monitoring are often used. .

Plan l-monitoring using such a monitoring screen display device is as follows:
This is particularly important during operational processes where the Plan 1 state is unstable, such as from start-up to normal operation of the plant, or from normal operation to shutdown. Therefore, a monitoring screen is required for each event or system depending on the operating process.

Generally, there are multiple operators assigned to a plant, and in the above-mentioned monitoring screen display device, the display device that displays the monitoring screen is such that each operator can arbitrarily select and view the monitoring screen. Multiple units were installed to allow for.

(Problem to be solved by the invention) By the way, when each operator monitors the plant status,
In many cases, the situation is judged while simultaneously viewing not only one monitoring screen but also other monitoring screens that are related to the operation of the plant.

However, since the number of display devices is fixed, if each operator attempts to display a desired monitoring screen on each of the plurality of display devices, there may be a shortage of display devices. Furthermore, if some operators occupy a large number of display devices, other operators may not be able to perform their original monitoring because they have no display devices to use.

As described above, the conventional monitoring screen display device has a problem in that all operators cannot arbitrarily display a plurality of monitoring screens to monitor the plant status.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and provide a monitoring screen display device that allows all operators to display a plurality of monitoring screens at their discretion.

[Configuration of the Invention (Means for Solving the Problems) For this purpose, the present invention stores in advance each monitoring screen corresponding to each monitoring target of the plant, and allows the operator to select any one of the monitoring screens. Select a plurality of groups and set each group, memorize the correspondence between each set group and each monitoring screen, and arbitrarily select one of the plurality of groups. The present invention is characterized in that a plurality of corresponding monitoring screens are multi-displayed on one screen.

(Operation) This allows all operators to arbitrarily display a plurality of monitoring screens on one screen of their respective display devices.

(Embodiments) Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 shows a block diagram of a monitoring screen display device according to an embodiment of the present invention. In the figure, a monitoring screen storage device 1 is used to monitor a plant 2.
While storing a plurality of monitoring screens corresponding to each monitoring target within the plant 2, screen information indicating the plant status is created from each monitoring screen based on detection information input from the plant 2.

The display device 3 displays a monitoring screen, and a touch screen 3a for various operations is attached to the screen. In addition, this display device 3
has a function of dividing the screen into a plurality of areas and displaying a plurality of monitoring screens in multiple areas, for example, as shown in displays A to D in FIG. 3b.

The input device 4 is a keyboard for inputting characters and numbers. The monitoring screen setting means 5 is used by the operator to arbitrarily set the multi-display screen and other various display screens. The monitoring screen display control means 6 displays various screens designated by the operator on the display device 3.

Note that in the figure, the display device 3. Input device 4° Monitoring screen setting means 5. Although only one monitoring screen display control means 6 is shown in the figure, a plurality of monitoring screen display control means 6 may be provided depending on the number of operators.

With the above configuration, in order to monitor the plant, let us assume that there are n monitoring screens, for example, "A water supply system" and "B water supply system", as shown in Figure 2. Each monitoring screen is assigned a number from 1 to n and a monitoring screen name.

Furthermore, as shown in FIG. 3, each monitoring screen is classified by plant system, etc., and a classification name is given to the classification, for example, "Boiler 1" or "Boiler 2."

In addition, the display screens when multiple monitoring screens are displayed on the display device 3 are classified in advance, and as shown in FIG. A name such as "r4 screen display part 2" is given.

The screen information set as described above is stored in the monitoring screen storage device 1.

FIG. 5 shows the setting of the display screen and the display operation. That is, when the operator performs a predetermined activation operation using the input device 4 of this monitoring screen display device, the screen information is read out from the monitoring screen storage device 1 (process 101).
A process selection screen is displayed based on that information.

As shown in FIG. 6, this process selection screen consists of a classification selection area a on the left half of the screen and a group selection area b on the right half.
and an execution selection area C at the lower right. Further, the classification selection area a consists of a single screen selection area Mi1 on the left half and a group selection area A2 on the right half.

Then, in the 1-screen selection area Mi 1, the monitoring screen classification name shown in FIG. 3 is displayed along with the serial number from 1 to 10.
In the group selection area a2, the multi-screen classification names shown in FIG. 4 are displayed together with the serial numbers 11 to 20.

In this case, only the serial numbers 1 to 10 are displayed in the group selection area b, and the characters "display j" and "setting" are displayed in the execution selection area C (process 102).

Next, if, for example, you specify No. 11 "4th screen No. 1" in the group selection area a2 using the touch screen 3a (Y in process 103), the corresponding screen information that has already been registered will be displayed in the group selection area b. displayed in (
Process 104). However, in this case, since the screen information has not yet been registered, it will not be displayed.

Here, when registering the screen information, the operator selects "Settings" in the execution selection area C using the touch screen 3a.
Specify. When this "setting" is specified (Y in process 105), a display setting screen is displayed next.

FIG. 7 shows an example of the display setting screen for setting four monitoring screens. In the figure, the monitoring screen setting area d in the center of the screen displays a display for inputting four types of classification names and monitoring screens, respectively.
A display for inputting a group name is displayed above it. Further, in this case, a "menu" for returning to the display of the process selection screen is further displayed in the execution selection area C (process 106).

Here, the operator arbitrarily determines four monitoring screens to be multi-displayed on one screen as one group, and enters the classification and monitoring screen number of each monitoring screen into the input device 4 according to the classification explained in FIG. Enter more information. Next, the group name is determined, for example "Boiler A screen", and input into the area (process 107).

Next, when the operator specifies "registration" in the execution selection area C (Y in process 108), the input screen information such as the monitoring screen and group name is stored in the monitoring screen storage device 1 (process 109). ).

Here, for example, if "display" is specified in the execution selection area C (Y in process 110), the four monitoring screens set above are actually displayed in multi-display (process 111).

This allows you to confirm the settings.

Next, when you specify "Menu" in execution selection area C (
Y in process 112), the process returns to the display of the process selection screen (proceeds to process 102).

The operator sets such screen information for each classification of the multi-display shown in FIG. 4. As a result, for example, as shown in FIG. 8, for each multi-display classification,
A plurality of groups are set, a plurality of monitoring screens are set for each of these groups, and information about the set screens is stored in the monitoring screen storage device l.

After this, while the process selection screen shown in FIG. 6 is being displayed, suppose that the operator specifies, for example, No. 11 "4 Screens 1" in the group selection area a2 as described above.
Y in process 103), each group name set above is displayed in group selection area b (process 104).

Here, when a desired group name and "display" in execution selection area C are specified (Y in process 113), the monitoring screen of that group is displayed in multiple ways (process 114).

Although not shown, there is a "menu" display in the execution selection area C of the display screen, and when you specify that display (
Step 115 (Y), the display returns to the processing selection screen (proceed to step 102).

For example, while the process selection screen is displayed, if the operator specifies "Boiler 1" in the 1 screen selection area Mi1, the classification name "Boiler 1" shown in FIG. 3 will be displayed in the group selection area b. The name of each monitoring screen corresponding to is displayed.

Next, by specifying each monitoring screen name and "display", the one specified monitoring screen will be displayed.

Furthermore, while displaying the process selection screen, for example, "4
When specifying already set display screens such as "Screen 1", "Boiler A screen", and "Settings", the display setting screen shown in FIG. 7 is similarly displayed. In this case, since each piece of information set on that screen is displayed, the operator can arbitrarily change the settings by re-entering the desired location.

Similarly, when a preset display screen is specified for (1) screen display, such as "Boiler 1" and "Settings," a predetermined setting screen for setting a monitoring screen group is displayed. This allows you to make arbitrary settings.

As described above, according to this embodiment, various monitoring screens are stored in the monitoring screen storage device 1 in advance, and the operator selects any plurality of monitoring screens from among those monitoring screens to set each group. Then, the correspondence between each set group and each monitoring screen is stored. By arbitrarily selecting one of the plurality of groups, a plurality of corresponding monitoring screens are displayed on one screen.

This allows all operators to display a plurality of desired monitoring screens on one screen of the display device. Therefore, unlike in the past, inconveniences such as some operators occupying the display device and other operators running out of display devices to use do not occur.

In addition, since multiple monitoring screens can be displayed simply by performing a touch operation on the touch screen 3a, a desired screen can be quickly displayed without having to specify multiple monitoring screens each time the screen is displayed. I can do it.

Incidentally, in the above-mentioned embodiment, as shown in FIGS. 6 and 7, the process selection screen and the display setting screen are separate, but they can also be combined into one screen. FIG. 9 shows an example of the screen display in that case. In the figure, the classification selection area a is placed on the left side of the screen, and the group selection area b is
is formed in the center. Further, the configuration of the multi-screen is displayed on the display section d on the right side, and the classification of the monitoring screen and its number is displayed on the setting content display section e below it. and,
An execution selection area C is formed in the lower right corner, and various display and registration selections are made here.

When an operator operates with this screen configuration, he selects one monitoring screen in classification selection area a and group selection area b, then specifies "single screen display" in execution selection area C, and selects one monitoring screen in classification selection area a and group selection area b. Display the monitoring screen. In addition, one multi-display group is specified in the classification selection area a and the group selection area b, while the display area d and the setting content display area e
Then, enter the desired display position and monitoring screen, specify "registration" in execution selection area C, and set the multi-display screen.

Through such processing, similar to the above embodiment, on one screen,
Predetermined displays and display screen settings can be made.

In each of the above embodiments, the touch screen 1 is used to specify display items on the screen, but it goes without saying that other coordinate input devices may be used. Also,
Instead of inputting the coordinates, the selection may be made by inputting the serial numbers displayed in the classification selection area a and the group selection area b using an input device.

[Effects of the Invention] As described above, according to the present invention, various monitoring screens are stored in advance, and each group is set by selecting an arbitrary plurality of monitoring screens from among the monitoring screens. By selecting a group, multiple corresponding monitoring screens are displayed on one screen, so all operators can display multiple desired monitoring screens on one screen of the display device. You will be able to do this.
