[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the functional blocks of the screen display device according to the first embodiment of the present invention, and FIG. 2 shows the appearance of the screen display device. In the screen display device of the present embodiment, each base screen obtained by dividing the plant process flow screen into a plurality of parts is stored in advance in the base screen memory 10.

The display screen 11 for displaying an arbitrary base screen read from the base screen memory 10 is provided with two position sensors 12 and 13 which are orthogonal to the frame portion. The position sensors 12 and 13 detect the position of the memo pen 14 for drawing memo information on the display screen 11 or the position of another object (such as an operator's finger) based on the orthogonal XY coordinate system.

Coordinate position signals output from the position sensors 12 and 13 are given to the first driver 16 via the terminal 15a of the touch mode selection switch 15 or via the terminal 15b of the touch mode selection switch 15. It is given to the second driver 17.

The touch mode selection switch 15 is a switch for selecting a normal touch operation performed on the display screen 11 for operation monitoring and operation of the plant and an operation of inputting memo information by the memo pen 14. .. With this touch mode selection switch 15, when the terminal 15a side is selected, a memo information input operation by the memo pen 14 is selected, and when the terminal 15b side is selected, the touch operation in the normal operation is selected.

The first driver 16 converts the coordinate position signal input through the touch mode selection switch 15 into address information of the memo screen memory 19 and the terminal 18a of the pen mode switch 18 for memo screen memory. I am writing in 19. The position sensors 12, 13 and the first driver 16 constitute a memo writing means.

The pen mode switch 18 is a switch for selecting writing and erasing of memo information. When the pen mode switch 18 is switched to the terminal 18a side, the memo information is written to the memo screen memory 19 and to the terminal 19b side. When it is switched, the memo information already written on the memo screen selected at that time is erased.

The memo screen memory 18 stores a memo screen composed of memo information drawn on a predetermined base screen on the display screen 11 in association with the base screen of the base screen memory 10. The second driver 17 also inputs the coordinate position signal input via the touch mode selection switch 15 to the screen controller 20.

The screen controller 20 has a central function of screen control in the screen display device. When the touch mode selection switch 15 is switched to the terminal 15a side, the screen controller 20 operates the base screen and the memo screen to combine the two screens. That is, a screen selection signal S1 is given to the base screen memory 10 and the memo screen memory 19 to select a base screen and a memo screen corresponding to each other, and the common memory 21 synthesizes (overlaps) them to form the converter 22. It is displayed on the display screen 11 via. Touch mode selection switch 1
When 5 is switched to the terminal 15b side, the coordinate position signal input via the second driver 17 is recognized as a touch operation signal input from the display screen 11 to the base screen, and the operation signal is The various commands shown are output to the base screen memory 10. By this command, for example, the memory content of the variable data stored in the base screen memory 10 is rewritten, and processing such as color change of the touched portion is performed. Further, the screen controller 20 rewrites the data of the instrument tag file 23 according to the command indicated by the operation signal and outputs it to the process controller as a control signal for actuators such as valves and pumps. The screen controller 20, the memo screen memory 19, the common memory 21, and the like constitute a synthesizing unit.

Further, the memo screen memory 19 is provided with a reset switch 24. By turning on the reset switch 24, the pen mode switch 18
The memo display during the memo writing, which is being written in the memo screen memory 19, can be erased via the terminal 18a.

Further, in this embodiment, a pen function controller 25 and a tag search controller 26 are further provided. The pen function controller 25 has a function of setting the display color of the memo information to be superimposed and displayed on the base screen to an arbitrary color. In addition, the tag search controller 26 is a device in the base screen stored in the base screen memory 10,
From the coordinate information of the device symbol (tag) and the memo coordinate information stored in the memo screen memory 19, a meter or a device within the memo range is searched. And instrument tag file 2
It is possible to issue an operation prohibition signal for prohibiting the operation of the searched instrument or device with respect to No. 3.

In the present embodiment configured as described above, the touch mode selection switch 15 is switched to the terminal 15a side,
By switching the pen mode switch 18 to the terminal 18a side, it becomes possible to write the memo information to an arbitrary base screen stored in the base screen memory 10.

For example, with the base screen displayed on the display screen 11, the memo pen 14 draws memo information at a desired position on the base screen. At that time, the position coordinates of the memo pen 14 are detected by the position sensors 12 and 13. This detection signal is input as a coordinate position signal to the first driver 16 via the touch mode selection switch 15, converted into address information there, and then stored in the memo screen memory 19. In this way, memo coordinate information (memo screen) for an arbitrary base screen is stored in the memo screen memory 19.

When erasing the memo information already written on the memo screen during the memo writing, the erasing operation is executed by turning on the reset switch 24. Further, when deleting the contents of the memo screen which has already been registered, the pen mode switch 18 is set to the terminal 18
The memo screen is erased by switching to the b side and applying the screen selection signal S1 from the screen controller 20. This allows new memo information to be written again on a certain base screen.

Next, when a display request for a certain base screen is given to the screen controller 20, as shown in FIG.
Also, the screen selection signal S1 is output to the memo screen memory 19 to select the base screen A and the corresponding memo screen B for which the request has been made. Both selected screens are combined in the common memory 21 and displayed on the display screen 11. As a result, the memo-added screen C in which the memo information R is written is displayed at the desired position on the base screen.

Further, in this embodiment, the memo information written on the base screen is set to an arbitrary color by the memo function controller 25. For example, as shown in FIG. 3, a device for which operation is prohibited due to a failure or the like is marked with a circle R. In such a case, an instruction is given to display the surrounding line R in red and display the other memo information in a color other than red. When a screen display request is made, the coordinate information of the instrument and device symbol in the base screen requested to be displayed and the memo coordinate information of the corresponding memo screen are fetched into the tag search controller 26 and written in red. Extract the instrument or device in the enclosed box R. Then, an operation prohibition signal for prohibiting the operation of the extracted instrument or device is output to the instrument tag file 23. The instrument tag file 23 outputs to the process controller so as to inhibit the operation of the instrument or the device to which the operation prohibition signal is issued.

As described above, according to the present embodiment, it is possible to easily add arbitrary information to the base screen for operation monitoring of the plant displayed on the display device such as CRT, so that erroneous operation is prevented. It is possible to improve the operation monitoring support function for the operator.

Further, the display data processing system of the memo screen is separated from the base screen system which is the main body of process operation monitoring, so that the display data processing system of the memo screen does not affect the base screen system. be able to. Further, not only the memo display but also the operation of the device at the memo location can be prohibited, so that the safety can be improved. Next, a second embodiment of the present invention will be described with reference to FIG. The parts having the same functions as those of the first embodiment shown in FIG. 1 are designated by the same reference numerals.

In the screen display device of this embodiment, the memo information corresponding to each base screen is stored in the window screen memory 30. Then, the window screen selection signal S2 provided from the screen controller 31 to the window screen control unit 32.
A predetermined window screen is selected by. Further, a screen selection signal is given from the screen controller 31 to the base screen memory 10 to select a predetermined base screen. The base screen and the window screen thus selected are combined in the common memory 33, and the window screen as memo information is displayed at a desired position on the base screen.

In this embodiment, the command for the mask mode or the overlap mode is input from the display mode switch 34. The mask mode is selected by selecting the terminal 34a side with the display mode switch 34, and the overlap mode is selected by selecting the terminal 34b side. In the mask mode, the window screen is displayed with priority over the base screen, and the portion of the base screen overlapping the window screen is not displayed. In the overlap mode, as in the first embodiment, a window screen with a transparent background is displayed over the base screen.

A screen with a memo synthesized in either the mask mode or the overlap mode is displayed by the converter 2
Display on the display screen 11 via 2 is the same as in the first embodiment.

Next, the operation of this embodiment will be described.
The operation until the memo information is registered in the window screen memory 30 is the same as that in the first embodiment, so the operation thereafter will be described.

When an arbitrary window screen is selected by touching the display screen 11, the window controller 31 gives a window screen selection signal S2 to the window screen controller 32. The window screen selected by the window screen selection signal S2 is read from the window screen memory 30 and is overlaid on the base screen in either the mask mode or the overlap mode. That is, in this embodiment, an arbitrary window screen can be combined with a certain base screen.

For example, as shown in FIG. 5, by connecting a plurality of the display devices of FIG. 4 via the bus line 41, the manager displays a message from one of the display devices 40-n to the operator on the window screen. By writing, there is an advantage that the operator on the other display device 40-1 can see the message of the administrator by selecting the same window screen.

In each of the above embodiments, the position sensors 12, 13 provided on the display screen 11 for displaying the base screen are shown.
I am using the to enter memo information, but the display screen 11
Even if the memo coordinate information is not integrated, the memo coordinate information may be input by another method as long as the memo coordinate information corresponding to the base screen can be obtained. Next, a third embodiment of the present invention will be described.

FIG. 6 shows the functional blocks of the plant monitoring system according to the third embodiment. In the plant monitoring apparatus according to the present embodiment, the storage unit 50 stores the symbol information representing the process equipment, the piping and the like by symbols, and the fixed information processing unit 51 and the variable information processing unit 52 receive the screen display request, and The symbol information of the display screen is extracted from the storage unit 50, and the symbol information is sent to the display processing unit 53. Then, the display processing unit 53 is configured to combine the symbol information with the monitor screen in response to the screen display request and display the monitor screen on the display unit 54 including a CRT.

After extracting the symbol information of the display screen, the variable information processing unit 52 can always take in a process signal from the variable information input unit 55 and perform a process for displaying the symbol on the display unit 54.

Further, as shown in FIG.
An operation unit 56 is provided on an operation console arranged close to the. The operation unit 56 has a permission switch 57 for making the additional information receivable, an erasing switch 58 for erasing the writing information, and a prohibiting switch 59 for inhibiting the erasing of the writing information. Further, the operation unit 56 is provided with a writing screen 60 on which the same image as the monitoring screen displayed on the display unit 54 is displayed.

On the writing screen 60, a pen input transparent board 61 serving as an additional information input section is placed. The monitoring screen displayed on the writing screen 60 can be seen through from the pen input transparent board 61. When a desired character, figure, or the like is written on the upper surface of the transparent board 61 for pen input by the light pen 62, the position information of the writing locus is output to the additional information processing unit 63 as writing information. That is, if a memo is written on the upper surface of the pen input transparent board 61 corresponding to the see-through monitoring screen, only the writing information indicated by the locus is extracted. Additional information processing unit 63
Edits the writing information input from the pen input transparent board 61 and outputs it to the display processing unit 53. Next, the operation of this embodiment configured as described above will be described.

A desired monitor screen is displayed on the display unit 54 in order to monitor the operating state of the plant. For example, assume that the monitoring screen shown in FIG. 7 is displayed. The same monitoring screen is also displayed on the writing screen 60 of the operation unit in order to clarify the monitoring target portion with respect to this monitoring screen.

Next, when the permission switch 57 is pressed, the additional information input unit 61 and the additional information processing unit 63 are ready to input additional information. In this state, the light pen 62
The part to be monitored is surrounded by a dotted line in the pen input transparent board 61, and its meaning is described in sentences. If pump A displayed on the monitoring screen is in the inspection state,
A supplementary explanation to that effect is written on the pen input transparent board 61.

The trajectory information of the light pen 62 is input to the additional information processing section 63. The additional information processing unit 63 converts the locus information (writing information) from the pen input transparent board 61 into position coordinate information corresponding to the monitoring screen on the display unit 54 and outputs the position coordinate information to the display processing unit 53. Then, the display processing unit 53 synthesizes the write information with the data of the monitor screen currently displayed on the display unit 54, and creates the synthesized screen information in which the write information is superimposed and displayed on the monitor screen as shown in FIG. To do. The combined screen information is displayed and output on the display unit 54.

As a result, the operator who is monitoring the plant while looking at the display unit 54 can quickly confirm the monitored portion and can easily add the necessary information in a free format according to the operating condition.

When erasing the additional information, the erasing switch 58 is pushed. As a result, all the additional information added to the display screen is erased. Further, in order to prevent the additional information added on the monitor screen from being erased by an erroneous operation, the prohibit switch 59 is pushed. When the prohibit switch 59 is pressed, even if the erase switch 58 is pressed thereafter, all the signals of the erase switch 58 are canceled as long as the display screen is displayed.

As described above, according to this embodiment, the same image as the monitor screen of the display unit 54 is displayed on the write screen 60 of the operation unit 56, and the pen input transparent board 61 is placed on the write screen 60. However, since the pen writing information is input from here to correspond to the monitor screen of the display unit and synthesized on the monitor screen, necessary additional information can be easily added to any position on the monitor screen, and the operator can monitor the part to be monitored. It is possible to get a clear understanding and obtain the information necessary for operation monitoring from the same screen. As a result, it is possible to prevent erroneous judgments and erroneous operations by the operator, and it is possible to promptly take appropriate measures during plant operation.

In this embodiment, the additional information is not written directly on the display unit 54, but the additional information is written on the operation unit 56 provided separately from the display unit 54. The posture is natural and the work is easy.

In the third embodiment, the additional information on the monitor screen may be displayed in a special display color different from the display colors of other symbols. Further, if the line thickness of the additional information can be changed to an arbitrary thickness, a higher effect can be expected.

Also, a plurality of CRs are used in a medium or large scale plant.
When a plurality of operators are used to monitor the operation of the plant using T, operation instructions, messages to be communicated between the operators are generated. At that time, by connecting a device having the same configuration as that of the present embodiment via a data transmission line, other operators (CRT) can obtain necessary information via the monitoring screen without leaving the seat while continuing the monitoring. Can be communicated to.
