The contents of areas 17 to 19 described above are information for displaying one screen, and the number of screens that can be displayed continuously is determined depending on the system scale. In FIG. 3, ten screens can be sequentially displayed in one operation procedure.

Next, the operation of the plant monitoring and control system having the above configuration will be explained.

In order to monitor the plant 1, plant data is inputted from the plant data input unit 2 at regular intervals, and based on this plant data, the status file creation unit 3 stores the plant status, faults, etc. in the auxiliary storage device 16. Digital signals such as data, analog signals such as process values,
A state file 4 of pulse signals such as integrated values is created, and a graphic screen is displayed on the CRT display device 7 using the graphic screen display unit 5.

[0027] When displaying a graphic screen, CR
The operator operates the keyboard 8 of the T display device 7 and the mouse 9 as a pointing device to
It is displayed on the display device 7. In addition, the operator performs the same operation to develop the screen of the display section 6 other than the graphic screen display.

In the embodiment of the present invention, the above is the normal display operation, but automatic display can also be performed according to the following operating procedure.

The operation procedure storage unit 11 is stored in the operation procedure storage unit 11 when the operator
The procedures operated by the operator using the T display device 7, keyboard 8, and mouse 9 are stored, and an operation procedure file 10 is created.

[0030] When storing this operating procedure, a key on the keyboard that starts storing the operating procedure with a single touch,
Alternatively, the icon symbol on the CRT screen is registered to the CPU 16 by the operator. Also, register the operation method for displaying the screen, for example, whether to expand to the next screen every time a key is pressed or to automatically expand at regular intervals.

Furthermore, for example, in a water treatment plant, treated water is sent to several distribution reservoirs.
If the water level in a distribution reservoir is below a certain level, it will be displayed on the graphic screen of the reservoir in order to check the water supply amount, and if the water level in the distribution reservoir is above the standard, it will be displayed on the graphic screen for the next confirmation. If you want to add a certain condition to the operating procedure, you also register the condition for displaying that screen.

An example of the above operation procedure registration screen is shown in FIG. The screen shown in FIG. 4 is a screen that is called up when the operator wants to register an operating procedure.
01, or an icon number for operation with the mouse 9 is set in step S102. In Figure 4,
It shows that a key is assigned to the function key F1 to display the operation procedure to be performed from now on. Note that the operations in steps S101 and S102 are as follows:
Only one of them may be registered.

Next, the method of operation is shown in step S.
103 for registration. If "one touch" is selected as this operation method, step S1
01. It is now possible to display a series of screens in sequence each time you operate the keys and icons registered in S102, and if you select "Automatic", the screens will be automatically displayed in sequence at a certain period of time. I will continue to do so.

If "automatic" is selected, then the display time of one screen is set in step S104. In this case, you can change the operation method for each screen to be displayed, and even if you set it to automatic mode, you would like to expand one screen at a time by pressing a key instead of automatically expanding the screen on a certain screen. In some cases, the screen can be set to expand only by key operations.

When the above settings are completed, press the keyboard 8 while looking at the CRT display 7 to display the normal screen.
or by using the mouse 9.

Through this operation, the contents of the operation performed by the operator are stored in the operation procedure storage section 11 and saved in the operation procedure file 10.

All operations by the operator are stored in this operating procedure file 10, but when selecting a screen in menu format, you do not want to see the menu screen, but rather the screen that is finally expanded from the menu. Since we want to display the menu screen with one touch, it is not necessary to display the menu screen.In such a case, it is recommended to cancel the menu screen operation and display only the final screen. can.

Next, based on FIG. 5, there is a condition setting function that sets a certain condition when displaying a screen, and makes the next screen different depending on whether the condition is met or not. explain.

FIG. 5 shows an example of a graphic screen display when the operating procedure is being saved. First, the display 201 shows a display indicating that the operating procedure is being saved on this graphic screen.

Display 202 is a cancel icon that, if selected when there is no need to store this graphic screen, will not be saved in the operating procedure file 10.

Display 203 is a conditioning icon for setting conditions when displaying this screen. By selecting this icon, a condition setting window like display 204 is displayed. In this condition setting window 204, conditions for displaying this screen are set. In the example of Figure 5, only when the water level of the xx distribution reservoir is outside the set range or the water level of the □□ distribution reservoir is not within the set range,
Conditions are set to display this graphic screen and not display anything else.

Display 205 is an icon for changing operation behavior, and by operating this icon,
A window for changing the operation method will be displayed. In the operation change window, you can set whether to display one-touch display or automatic display, and when automatic display is selected, you can set or change the screen display time.

In this manner, a series of operating procedures are stored in the operating procedure storage section 11 and saved in the operating procedure file 10.

[0044] The operating procedure registered as above is as follows.
When the icon is hit by a key on the keyboard 8 or the mouse 9, the operation procedure display section 12 reads out the icon.
A graphic screen is displayed on the CRT display device 7 according to the procedure operated by the operator.

[0045] If display conditions are attached when displaying the screen, the screen operation condition determining unit 13 determines the display conditions, and if the conditions are met, the preset conditions are applied. If the conditions are not met, that screen will not be displayed and the next graphic screen will be displayed.

Furthermore, if the user wishes to change or confirm the operating procedure midway through, the operating procedure can be easily changed by displaying an operating procedure confirmation screen as shown in FIG.

In the example of FIG. 6, the function key F
1. A list of the contents of the operating procedures assigned to the icon number I1 is displayed, and displays 301, 302, and 303 are displayed simultaneously for adding, changing, and deleting operating procedures. Therefore, select the display screen number with the arrow keys or click with the mouse and click
By selecting the "Add" display 301, "Change" display 302, or "Delete" display 303, you can perform operations such as canceling the display of the selected screen, changing the display conditions, changing the operation method, and changing the automatic display time. It can be carried out.

As described above, in the plant monitoring and control device of this embodiment, the display operation procedure for a series of screens to be displayed graphically is registered, and the operation procedure is registered by using keys or pointing device operation. Accordingly, plant status information can be sequentially graphically displayed with a single touch, or plant information can be automatically and sequentially displayed graphically at regular intervals according to the operating procedure. Therefore, especially in large-scale plants that operate 24 hours a day, a large number of similar screens must be switched and displayed one after another every time a shift occurs.
If work is required to check the plant status, this work can be done easily.

Note that the present invention is not limited to the above-mentioned embodiments, and the following embodiments are also possible.

[0050] By adding a schedule function to the function of continuously displaying the screen, instead of relying on one-touch operation by the operator, it is possible to automatically display the screen on the CRT display device at the scheduled time, such as during regular inspection work. By continuously displaying graphic screens, it is possible to prevent the operator from forgetting the confirmation work, and it is possible to reduce the burden of monitoring.

[0051] Also, when displaying the screen, return to the previous screen,
By loading various editing functions such as skipping one screen, interrupting continuous display, and restarting continuous display,
It is possible to build a system that is easier to operate. Furthermore, if equipment can be operated on the screen, safety measures can be taken from the screen, especially in the case of conditional displays.

[0052] Furthermore, if the operating procedure file can be saved in an external storage device such as a floppy disk,
When it is desired to change the operations assigned to the function keys of the keyboard depending on the season, the operation procedure can be restored from the floppy disk corresponding to the season.

[0053]

[Effects of the Invention] As described above, according to the present invention, a series of operating procedures can be registered, and graphic screens can be developed sequentially with a single touch by key operation or pointing device operation, or automatically at regular intervals. It is possible to have the operator check the plant status while the graphic screen is being displayed, eliminating the burden on the operator to think about which screen is best to display next. Appropriate plant monitoring can be performed while being lightweight.

[0054] Furthermore, display conditions are added to the graphic display operation procedure, and if an abnormality occurs, related more detailed information is displayed, and if normal, the display moves to the next graphic screen. This will make plant monitoring even more reliable.
