Abstract

PURPOSE:To prevent plant equipment from generating misoperation due to operator's individual operation by allowing the operator in charge of the operation to execute only the operation permitted by a supervisor and other operators. CONSTITUTION:The information of plant equipment 1 is inputted to an input device 3 in the plant operation device 2 and then inputted to a display processing means 4 as a processable signal. The means 4 for displaying plant information displays the plant information on an operation display device 10 and a permission display device 11. Only when plant operation to be executed by the operator is permitted by the supervisor or co-operating operation with other operators is obtained, an operation command is outputted to the plant equipment 1. Consequently, the generation of misoperation due to operator's independent operation or mistake can be prevented and sure and accurate plant operation can be attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a plant operation device for operating plant equipment by touching a display screen of a display device.

(Prior technology) In recent years, instead of monitoring operation using lamps and instruments on the operation control panel of large-scale and complex plants such as nuclear power plants, operation monitoring has become possible using symbols, per charts, numerical values, etc. on a CRT screen. CRT-based plant operations have become mainstream.

In the past, CRTs were mainly used for monitoring purposes, but recently, CRTs that are also used for operation have become popular.
operations are becoming popular. With CRT operation, plant monitoring and operation can be performed on the same screen, making it easy to understand the plant status. Also, by replacing the many switches and controllers that had to be physically placed on the control panel with touch operations on the CRT screen, there are advantages such as space savings.

FIG. 6 shows an example of a conventional plant operation device using CRT operation. Plant information from the plant equipment 1 is input to the input device 3 of the display processing means 2 at any time, converted into processable data, and then output to the display processing means 4. The display processing means 4 displays the plant information on the display device 5.

An example of the screen displayed on this display device 5 is shown in FIG. The operator monitors the plant on the screen 50 displayed on the display device 5, and when it becomes necessary to operate plant equipment, the operator operates the plant by touching the screen 50 on the display device 5. An example will be explained in which the stopped pump A is operated on the screen 50 in FIG. 7. The operator selects the pump A displayed on the display device 5.
Touch . Then, the touch sensor 6 provided on the front surface of the display device 5 sends position information of the touched portion on the screen to the operation command generation means 7.

FIG. 8 shows an operation device list DATI (a) processed by the operation command generation means 7 and an operation switch list DAT2.
(b) is a data configuration diagram of operation command information DAT3 (c).

Based on the position information, the operation command creation means 7 performs the operation command creation means 7 as shown in FIG.
The operation device list DATI in the format shown in a) is searched and the device touched by the operator is identified.

The operation equipment list DATI is a list showing the correspondence between the screen coordinates of the display device 3 and the displayed plant equipment.
The operation command creation means 7 extracts data whose value in the display position column XYI of this operation device list DATI matches the position information, and identifies that the touched device is pump A from the contents of the device type 11 PID. . Furthermore, the identified pump A is provided with operation command information DA in the format shown in FIG. 8(c).
It is written in the requesting device column OPI of T3 and the display processing means 4 is notified. Upon receiving the notification from the operation command generating means 7, the display processing means 4 changes the color of the pump^ symbol on the display screen 50 to indicate that the pump A has been selected as the operation target. At the same time, as shown in the display screen 51 shown in FIG. 9, an operation switch 52 is displayed as a symbol surrounded by a frame at the bottom of the screen. Operation display screen 51 in FIG. 9
In the above example, ``run'' and ``stop'' are operation switches that specify the operation of the pump, and ``command'' is an indication of a switch that ultimately sends an operation command to the output device 8.

The operator touches the "Run" switch on the screen shown in FIG. As in the case where the pump A is touched, the operation command creation means 7 inputs position information from the touch sensor 6, and based on this position information, it creates an operation switch list DAT2 in the format shown in FIG. 8(b). Search and process the display position column XY2 of
The touched switch is identified as "operation". Furthermore, the specified operation content "driving" is written in the requested operation aIOP2 of the operation command information DAT3 and is notified to the display processing means 4. Upon receiving this notification, the display processing means 4 displays the 9th rj!
The symbol of the ``Run'' switch is displayed in different colors on the screen 1. The operator can clearly identify the equipment and operation details that he or she wants to operate from the displayed part on the screen 5l of the display device 5 in different colors. After confirming that the "operation" switch is touched, touch the "command" switch 52. Upon receiving the position information from the touch sensor 6, the operation command creation means 7 searches for the DAT 2 in the same way as when the "operation" switch is touched. Processing is performed, and the touched switch is identified as a ``command''. If the specified content is a ``command'', the operation command creation means 7 performs the final processing to identify the touched switch as a ``command''. The contents of the operation command information DAT3 are sent to the output device 8 as an operation command.The output device 8, based on the operation command,
Outputs a freezing motion command signal to the control device M9. The control device 9 inputs a drive command signal from the output device 8, performs control processing, and outputs a control signal to the plant equipment l.

In this way, the plant operating device can operate the plant equipment by touching the display screen on the display device 5.

(Problem M to be solved by the invention) However, since the operation of plant equipment is generally carried out according to the instructions of the manager who is responsible for plant operation, it is necessary to obtain the manager's consent to operate the equipment. need to get it. In particular, when operating equipment that is important to the plant, operation by a single operator is prohibited, and operation can only be performed in the presence of multiple operators or a manager. Alternatively, in the case of hard switches, we have applied keys to the switches. On the other hand, in CRT operations using conventional technology, operations can be performed by a single operator, so important equipment is operated without instructions from the administrator, and erroneous operations due to operator misconceptions, WJ differences, etc. There was a risk that this would occur.

Therefore, the present invention outputs operation commands to plant equipment only when the plant operation that the operator is about to perform is permitted by the administrator or when cooperative operation with other operators is obtained. 'Wi's purpose is to provide plant operation equipment that allows practical plant operation. [Structure of the Invention] (Means for Solving the Problems) The plant operating device of the present invention displays plant information on a display device different from the display device by the display processing means, and also displays plant information on a display device different from the display device. Inputting positional information of a touch on the screen from a touch sensor provided on the front of the device, searching the display contents of the other display device based on this positional information, and permitting the operation command creation means to create an operation command. Alternatively, it is equipped with an operation management means to disallow permission.

(Function) According to this plant operation device, plant information input from the input device and information regarding the plant operation that the operator is about to perform are displayed on the permission display device in addition to the operation display device. , the administrator can check the equipment that the operator is trying to operate on the display screen of the permission display device.

In addition, the operation management means detects position information from a touch sensor provided on the front of the permission display device, and notifies the operation command generation means of a command to permit or disallow the operator to perform plant operation. The creation means determines the content of the command from the operation management means, and can send the plant equipment operation command to the output device only when permission is granted for plant operation.

This prevents erroneous operation due to operator's independent operation or misunderstanding, and enables reliable and accurate plant operation.

(Example) Examples of the present invention will be described below with reference to the drawings. 1st
The figure is a diagram showing an embodiment of the present invention. In the figure, the 6th
The same symbols as in the figure indicate the same or equivalent parts. Information on the plant equipment 1 is input to the input device 3 of the plant operation device 2, and is input to the display processing means 4 as a processable signal. The display processing means 4 is a means for displaying the plant information, and includes an operation display device 10 and a permission display device a.
Display plant information on tt.

The operation display device 10 is a display device that provides the plant information to the operator and allows the operator to operate the plant on a display screen based on the information.

The permission display device 11 is a device for providing the plant information to the manager and for the manager to give instructions for permission or disapproval when the operator performs plant operations. The front of these display devices 10 and 11 detects the position of the touched part on the display screen and displays the position information, respectively.
Touch sensors 13 and 14 are provided to notify the operation command generation means 7 and the operation management means 12. Operation management means
2 is a means for outputting instructions given by the administrator from the permission display device 1l. The operation command creation means 7 is means for creating an operation command for operating plant equipment, and outputting the operation command to the output device 8 only when execution of the plant operation is permitted.

Operation equipment list DATL. Operation switch list DAT2
includes data that is searched by the operation command generation means 7 when specifying the equipment and operation content on the display screen touched by the operator. In the operation command information DAT3,
The operation command generating means 7 writes the contents of the device operation, and the operation management means 12 writes an instruction for permission or disapproval of the operation. Permission switch list DAT4
In is written data that is searched by the operation management means 12 in order to specify the contents instructed by the administrator.

The output device 8 is a device that inputs an operation command from the operation command generation means 7, outputs a motion command signal to the control device 9 based on the operation command, and causes the control device 9 to control the plant equipment 1.

Next, the operation of the plant operation device configured as described above will be explained using a flowchart showing the processing procedure of the operation command generation means 7 and the operation management means 12 shown in FIGS. 2 and 3.

The input device 3 inputs information from the plant equipment 1 and sends the plant information to the display processing means 4. The display processing means 4 displays the plant information on the permission display device 11 in addition to the operation display device 10 that has conventionally been displayed.

During plant monitoring, a screen similar to the screen 50 shown in FIG. 9 described above is displayed on the operation display device 10 and the permission display device 11, for example.

Now, let us take as an example a case where the operator performs an operation to operate the pump A on both sides similar to the display screen 50 shown in FIG. 9, and the administrator permits the execution of the operation.

First, the operator inputs position information by touching the pump 8 symbol /l,H on the screen of the operation display device 10 (201). The touch sensor 13 sends position information of the touched part to the operation command generation means 7.

The operation command creation means 7 executes the operation equipment list DA shown in FIG.
Performs TI search processing (202), specifies pump A, and writes selection data of pump A to the requested device 41160Pl of the operation command information DAT3 shown in FIG. 5(c) (
203), request operation 1110P2 and operation permission f
The data of fjlFLG is cleared to zero (204). After that, a startup request is notified to the display processing means 4 (205),
Finish the process.

Upon receiving the notification, the display processing means 4 displays the bomb A symbol in different colors and the symbol of the operation switch at the bottom of the display screen as in the conventional manner, and displays the operation switch symbol on the operation display device 10 as shown in FIG. 5(a). The fifth screen 100 is displayed on the permission display device 11.
A screen 110 shown in Figure (b) is displayed.

Here, "operation" on the display screen 100 in FIG. 5(a)
``Stop'' and ``Command'' are indications of operation switches that have the same functions as those of the prior art. On the other hand, 1'``Permit'' and ``Not Permit'' on the display screen 110 are switches for the administrator to give instructions regarding the plant operation that the operator is about to perform. The operation switch display is a display that enables touch operations when that part is touched, and the operation switch display with a double frame simply indicates the status of the switch and indicates that touch operations cannot be performed from this display. In other words, the operation display device 10
Touch operations for selecting equipment, operation content selection, and "command" switch selection are possible from , and touch operations for selecting "permit" switch and "disallow" switch are possible from the permission display device 11 as instructions for plant operation implementation. Operation is possible. Operation display it! When the operation switch is displayed at 10, the operator then touches the ``Run'' switch.
When the aforementioned pump A is touched, the touch sensor 13 similarly outputs position information, and the operation command generation means 7 searches the operation switch list DAT2 shown in FIG. 4(b) to specify the operation content, It is determined whether or not device selection data is written in the requested device field OP1 (206). As a result of this judgment, if there is writing, the operation command information DAT3
Write the selection data of ``driving'' as the operation content to the requested operation i0P2 (2o7), operation permission 4IllIF
Clear LG Zero (208).

Furthermore, a processing start request is notified to the display processing means 4. The display processing means 4 changes the color of the symbol of the ``run'' switch and displays it on the operation display device 1o and the permission display device 11.

On the other hand, if the device selection data is not written in the request device column OPI (No in 206), request operation 1110P
2 and operation permission 4I! Each lFLG is cleared to zero (209).

The administrator confirms and determines the content of the operation that the operator is attempting to perform, that is, that he is attempting to operate pump A, by the color-changing display of the equipment and operation switches on the display screen of the permission display device 11. , instructions for performing the operation are given from the permission display device 1.1. In this example, the administrator touches the "permit" switch on the screen of the permission display device 11. The touch sensor 14 provided in front of the permission display device 11 sends positional information of the touched portion to the operation management means 12 as input information (301). Based on the position information from the touch sensor 14, the operation management means 12 activates the permission switch list OAT in the format shown in FIG. 4(d).
Search the display position column XY3 of 4, identify the instruction content from the administrator (302), and set 1 if the instruction content is "permitted" (303), and -1 if it is "not allowed". (30
4), operation command information DAT3 operation permission 4 [[Writes to FLG and notifies display processing request to display processing means 4 (3
05), the process ends.

Further, as a result of specifying the instruction contents, if there is no applicable item as a switch, the process ends. As a result, the display processing means 4 displays the operation permission 4 (“permission” based on the value of I FLG).
(if FLG=1) or “not allowed” (FLG=
-1) The color of the switch symbol is changed and displayed on the operation display device 10 and the permission display device M1■ according to each case, and in the case of 0, the color is not changed. The operator is. ``Permit'' or ``Disallow'' the display screen of the operation display device 10
The color-changing display of the switch allows you to confirm instructions from the administrator, and if permission is granted, to perform plant operations.''
The plant equipment 1 can be operated by touching the "command" switch, but if permission is not granted, the plant cannot be operated.

After the plant operation is permitted, when the operator touches the "command" switch on the display screen of the operation display device a 10, the touch sensor 13 sends position information to the operation command creation means 7, and the operation command creation means 7 sends the position information to the operation command creation means 7. The means 7 searches the operation switch list DAT2 and specifies that the 6 command "switch has been touched. After this, the operation command creating means 7 enters OPI in the requested equipment column and "bomp A" in the requested operation lIIOP2.
When it is determined that the selection data of I1 and the selection data of "operation" are respectively written (210, 21
1), depending on the contents of the operation permission column FLG of DAT3. Determine the status of the manager's instructions for the operator to perform plant operations, and only if the manager's instructions are permission, i.e., operation permission a.
Only when the value of IFLG is 1 (212), the requesting device 4! I
The contents of OP1 and requested operation @OP2 are sent to the output device 8 as operation commands (213), and the process ends. If the operator touches the "Command" switch even though the administrator disallows the plant operation that the operator is about to perform, the value in the operation permission column FLG of the operation command information DAT3 will be II-I I+ Therefore, the process ends without outputting the operation command.Furthermore, even if the operator touches the ``command'' switch before the administrator gives the instruction, the operation permission of the operation command information DAT3 +1! IFLG is O, so no operation command is output, and the process ends. On the other hand, if the device selection data is not written in the requesting device column OPI, requesting device @OP2 and operation permission fI1iFL
Clear G to zero and end the process (214). Also, device selection data is written in request device 4IIOP1. If the operation selection data is not written in the requesting device 110P2, the operation permission field FLG is cleared to zero and the process ends.

In the above explanation, the operation command creation means 7 searches the operation device list DATI and the operation switch list DAT2 based on the position information output from the touch sensor l3, and displays the corresponding device display and switch type display. If it does not exist, the process ends.

If an operation command is output to the output device 8 as a result of the above processing by the operation command generation means 7, the output device 8 outputs an opening command signal to the control device 9 based on this operation command.

Furthermore, the control device 9 outputs a control signal to the plant equipment 1 based on this opening command signal, and causes the plant equipment 1 to operate.

In this way, it is possible to add permission/disapproval procedures based on the manager's judgment immediately before the final operation step (the step of selecting the "command" display) by the operator who actually operates the plant equipment 1. Therefore, the plant equipment 1 that will be operated from now on and the state in which this equipment will be operated can be sufficiently confirmed, and a more complete plan and equipment operation can be executed.

In addition, in the above embodiment, the explanation was given using an example of a so-called switch, but it can be similarly applied to the case of a plant operation device in which a controller is touch-operated. Although an administrator was set up and explained to the operator, another operator could give permission/permission to the operator to execute the operation.
It is also possible to give permission from a display device with a touch sensor used by another operator.

In addition, in the above embodiment, the case where the administrator allows/disallows the operation is explained. The display of the permission/disapproval switch shown in the embodiment is canceled, the procedure of touching and specifying the plant equipment l is set as the role of the operation management means 12, the operation switch and the operation command are set as the role of the operation command creation means 7, and the administrator Cooperative operation is also possible, where the operator specifies the operation target and the operator performs the actual operation. Similarly, it is also possible to set up the above cooperative operation between multiple operators. In this case, the display device with a touch sensor on the side that first specifies the plant equipment 1 by touch becomes the permission display device 11, and the display device with the touch sensor on the side that specifies the operation switch and the operation command by touch is the device for operation. The plant operation device is constructed from the standpoint of 10.

Furthermore, in the above embodiment, the administrator's disapproval instruction was made as a step before the operator outputs the operation command, but it is also necessary to specify the touch designation of the operation device and the touch of the operation switch. It is also possible to request non-permission from the permission display device 11 at any time during the designation.

Further, in the above embodiment, a method of displaying the selected device/switch by changing its color has been described as a method of identifying the selected device/switch, but instead of changing the color, a flicker may be used. Further, a chime may be provided so that when the driver makes an operation request, the chime sounds to audibly indicate that the operation request has occurred.

[Effects of the Invention] As described above, according to the present invention, only the operations permitted by the manager and other operators are performed, so that it is possible to prevent erroneous operation of plant equipment due to operation by the operator alone. , the plant will be able to operate more safely.
