In this way, the apparatus of the present embodiment takes out the necessary operating devices and indicators from a plurality of system screens that need to be operated and monitored at the same time on the CRT screen A, and collects the combined operation end screen C into one. , And the necessary operation monitoring of the plant can be performed without switching the screen using this collective operation end screen C.

Hereinafter, in the case of editing and registering the collective operation end screen C,
The operation will be described with reference to the drawings.

During edit registration The operator operates the touch screen 2 or keyboard 3 on the CRT display 1 to select a system screen including items to be monitored. When the selection signal is input to the display screen control unit 5 via the operation content input unit 4,
The display screen control unit 5 requests the operation monitoring point display 6 to display the selected system screen. The operation monitoring point display unit 6 obtains the requested display information of the system screen from the system screen data management unit 9 and displays the system screen on the CRT display 1. That is, the system screen data management unit 9 stores display information of each system screen and a PID information table, which will be described later, in advance.

Before and after the above operation, the operator changes the collective operation end screen C from the collective operation end management unit 10 to the operation monitoring calculation control unit 7,
CR via display screen control unit 5 and operation monitoring point display unit 6
Call the T display unit 1. This set end screen C is the first C
When called by the RT display 1, the screen area is blank. Therefore, the operator operates the keyboard 3 to give a name to the upper area C9 of the collective operation end screen C. For example, if the collective operation end screen C is for starting a boiler, the title "Boiler starting collective operation end" is entered.

Next, the operator moves from the system screen B displayed at the screen position avoiding the collective operation end screen C to the collective operation end screen C.
The operation monitoring items such as plant equipment, for example, valves, pumps, etc. corresponding to the operation device or display device to be edited are touched on the touch screen 2. At this time, the correspondence relationship between the operation monitoring item and the operation device / display device pattern (for example, the second
(The relationship that the target value setting indicator pattern C1 corresponds to the manual valve B1 of the system screen B shown in the figure) is attached in advance and is stored in the system screen data management unit 9 as the PID information table 9A shown in FIG. Remembered Where PID (P
OINT IDENTIFICATION) is an identification code for identifying the plant device, for example, the manual valve B1 on the system screen B. In addition, "PID ₁ operation end index" in Fig. 3
Is a code for identifying the operation device pattern and the display device pattern corresponding to the PID ₁ , and “operation PID _i , ...”
And “display PID _k ...” represents an operation device pattern corresponding to the operation end, a symbol such as a marker in the display device pattern, and corresponds to FIGS. 5B and 5C described later. Is.

When the operator touches a necessary operation monitoring item on the system screen B on the touch screen 2, the signal is input to the display screen control unit 5 via the operation content input unit 4. The display screen control unit 5 converts this signal into PID information and sends it to the operation monitoring calculation control unit 7. The operation monitoring calculation control unit 7 uses this PI
P stored in the system screen data management unit 9 based on the D information
Extract the operation end index from the ID information table 9A,
It is passed to the operating end display control unit 8. The operation terminal display control unit 8 takes out the display pattern information corresponding to this index from the common symbol management unit 11 and passes it to the display screen control unit 5. That is, the common symbol management section 11 stores the operation end information table 11A shown in FIG. This operating end information table 11A represents detailed information in the pattern specified in the PID information table 9A in FIG. 3, and the "number of symbols in operating end 1" is the number of symbols displayed in the index pattern of operating end 1. Represents "X coordinate of symbol 1"
Represents the coordinates in the pattern, and the "symbol index of symbol 1" is a code for identifying the pattern of a marker, a push button, or the like. The operation terminal display control unit 8 transfers these pieces of information to the display screen control unit 5. The display screen control unit 5 displays this on the CRT display 1 via the operation monitoring point display unit 6.

The operator looks at the display on the CRT display 1 and touches the position of the touch screen 2 on the corresponding CRT display 1 in order to bring the pattern displayed there to a predetermined position in the collective operating screen C. To do. At this time, the display patterns C1 to C8 and the like are based on the left corner, and the pattern is displayed according to the touched position of the left corner. That is, when the touch screen signal is input through the operation content input unit 4, the display screen control unit 5 converts the position into X / Y coordinate information and passes it from the operation monitoring calculation control unit 7 to the operation end display control unit 8. As a result, the operating end display control unit 8 creates the operating end management table 8A shown in FIG. 5 (a).

In the figure, "X coordinate of operating end 1" and "Y coordinate of operating end 1" represent the coordinates of the left corner of the pattern C1 in FIG. Further, the "width of the operating end 1" and the "height of the operating end 1" represent the width and height of the pattern C1, which is the common symbol management unit.
Operation end information table 11 of FIG. 4 stored in advance in FIG.
Take out from A. The "operation end index of the operation end 1" is an identification code indicating that the pattern at this time is C1.

Further, the operation end display control unit 8 simultaneously with the operation end management table 8A, the operation item management table 8 in FIG. 5 (b).
B, the monitoring item management table 8C in FIG. 4C, the operation end information table 11A and the system screen data management unit 9 in FIG.
It is created based on the PID information table 9A of FIG. 3 stored in FIG. 3, and these tables 8A, 8B, 8C are stored.

Here, the operation item management table 8B of FIG. 5B and the monitoring item management table 8C of FIG. 5C represent the detailed display data of the operation end management table 8A, respectively, and the "operation" of the operation item management table 8B is displayed. The "X coordinate of the symbol 1" and the "Y coordinate of the operation symbol 1" represent, for example, the coordinates (these coordinates are predetermined) in the pattern C1 of the setting marker up push button switch C11 in the pattern 1C. . The "operation symbol index of operation symbol 1" is an identification code for specifying that the symbol is C11.

Similarly, the “X coordinate of the display symbol 1” and the “Y coordinate of the display symbol 1” in the monitoring item management table 8C are
It represents the coordinates of the marker C13 in the pattern C1, and the "display index of the display symbol 1" indicates that the symbol is C1.
3, "PID of display symbol 1" is manual valve B1
Is an identification code. The coordinates of these symbols and the symbol index are obtained from the operation end information table 11A shown in FIG. 4, and the PID specifying the relation between the operation and the displayed symbol and the plant equipment is the PID shown in FIG.
Extracted from information table 9A, operation item management table 8
B, monitoring item management table 8C is created.

In this way, the display screen control unit 5 displays the target value setting indicator pattern C1 of the plant equipment to be integrated from the system screen B displayed in the CRT screen A in the collective operation terminal screen C, and then the system If there is no more plant equipment to be integrated from screen B, another system screen B'is displayed in CRT screen A via touch screen 2 or keyboard 3.
(Not shown) is displayed in place of B, and the process of extracting the operation device pattern and the display device pattern of the plant equipment in the collective operation end screen C is executed in the same manner as above. The display screen control unit 5 repeatedly executes such processing to display all the system diagrams simultaneously requiring operation and monitoring in the collective operation terminal screen C, and the operation device display pattern C1 of the plant equipment necessary for operation and monitoring. When the collective operation end table for displaying ~ C8 is created, this is stored in the collective operation end management unit 10 via the operation monitoring calculation control unit 7. Further, the display screen control unit 5
Such a collective operation end table is created for each plant state or plant configuration block that requires operation monitoring, and a plurality of these are stored in the collective operation end management unit 10.

At the same time as when editing and registering, the operator operates the touch screen 2 on the CRT display 1 by operating the keyboard 3 to select the system screen necessary for operation monitoring, and the CRT display 1
Display above. If a situation in which it is necessary to operate some plant equipment and display the plant status at the same time while performing operation monitoring in this state, operate the keyboard 3 or the like to first perform the collective operation end management unit. Call one of the collective operation end screens C stored in 10. That is, in the collective operation terminal management unit 10, an operational terminal management table 8A, an operation item management table 8B, and a monitoring item management table 8C created for each collective operation terminal screen C are stored. When a selection signal is input from the keyboard 3 to the display screen control unit 5 from the operation content input unit 4, the display screen control unit 5 causes the collective operation terminal management unit 10 to select the collective operation selected via the operation monitoring calculation control unit 7. A set of tables 8A to 8C required to display the end screen is taken out and passed to the operation monitoring point display unit 6. As a result, as shown in FIG. 2, a desired collective operation end screen C is displayed on the CRT screen A by superimposing it on the system screen B previously displayed.
Is displayed.

When the operator looks at this CRT screen A and touches, for example, the setting marker raising push-button switch C11 in the target value setting indicator pattern C1, the signal indicates the operation content input section 4
Is transmitted to the operation monitoring calculation control unit 7 via the display screen control unit 5. As a result, the operation monitoring calculation control unit 7 outputs a command for increasing the target set value of the corresponding plant equipment PID to the plant control device (not shown) based on the operation item management table 8B that has been extracted previously. At the same time, the Y coordinate value of the target setting marker C13 which is the display symbol corresponding to the PID is increased by referring to the monitoring item management table 8C. As a result, the operation end screen C displayed in the CRT screen A
Target setting marker C13 in the target value setting indicator pattern C1
Rises. In addition, the PID output to the plant controller
When the target set value of is increased, the actual process amount (in this case, the feed water flow rate) is increased. Then, this value is fed back from the plant control device (not shown) to the operation monitoring operation control unit 7, so that the operation monitoring operation control unit 7 causes the operation monitoring operation control unit 7 to display the corresponding display symbol, that is, the marker C1 in the monitoring item management table 8C.
Increase the Y coordinate of 4. As a result, the actual value display marker C14 in the tone value setting indicator pattern C1 rises.

[Effects of the Invention] As described above, according to the present invention, the patterns of the operation devices and the display devices necessary for operating the plant are arbitrarily collected based on the original plan and are displayed on the CRT screen. As a result, many items can be operated and monitored collectively without switching the system screen one by one, and the operating efficiency of the plant is extremely improved.
