Description

  The present invention relates to a plant information display device and a plant information display method.

  FIG. 14 is a schematic diagram showing a system configuration example of a monitoring control system 100 of a central monitoring control system that is an example of a plant monitoring control system.

  In a process plant such as a nuclear power plant, a central supervisory control system is adopted. In the monitoring control system 100 adopting the central monitoring control method, for example, sensors installed in the field, and devices such as pumps or valves (FIG. 14 shows the case of “sensor” as an example) 101 to 103 are measured. The process data, device information, and the like are collected and managed in a process computer 106, which is an example of a process value management means, via the on-site network 104 or the dedicated cable 105 at a predetermined cycle (for example, around 1 second). The process computer 106 is connected to an input / output device 108 as a monitoring terminal device via a monitoring control network 107, for example.

  The input / output device 108 provides an information output function and an input function, that is, a function of a human machine interface (hereinafter referred to as “HMI”). The information output function and input function of the input / output device 108 are configured by, for example, a display device such as a liquid crystal display (LCD) device as a touch panel, or a display device and a pointing device such as a mouse. It is realized by doing.

  For example, in a plant information display device for a nuclear power plant, since the number of process data handled by the nuclear power plant reaches several thousand, information is often grouped in units called screens. That is, the screen is a visualization of information as an image.

  In the plant information display device, how the screen (information) is configured, that is, process data displayed on the display device at the same time, display method (digital display, bar chart display, trend graph, etc.), display layout, etc. Is set. A plant operator who is a user of the plant information display device can obtain necessary information by selecting a desired screen from the set screens.

On each screen, the process data is not only displayed as a numerical value, but also by using the methods (1) to (4) below, it is easy to understand the process data, and the load on the monitoring operation of the plant operator Mitigating.
(1) Process data display using a system diagram (2) Graphical display of process data using bar charts, etc. (3) Display of changes in process data trend graphs (4) Alarm display using tiles

  For example, the process computer 106 of the monitoring control system 100 shown in FIG. 14 uses vector graphics to draw a screen to be displayed on the display device. In vector graphics, coordinates such as points, lines, polygons, circles, arcs, etc., or character strings are written on VRAM (Video Random Access Memory) that directly corresponds to the pixels on the display device. Then, these figures and character strings are displayed on the display device.

  The conventional supervisory control system including the supervisory control system 100 requires specialized knowledge for correcting and remodeling the screen. Therefore, when a new device is installed on the site or a device that is no longer necessary due to facility modification is removed, it is not easy to modify the screen. Therefore, it takes a lot of time to reflect the modification of the field facility on the monitoring system. This difficulty of screen modification may delay the calming of the situation when an abnormality occurs in the plant.

  For example, if a permanent device of a plant to be monitored and controlled breaks down, and a temporary device is installed suddenly, the plant can be operated without being able to monitor the installed temporary device due to the difficulty of screen modification. There are things to do. Under this circumstance, when an abnormality occurs at a location where temporary equipment or the like cannot be monitored, there is a concern that the abnormality cannot be detected and the calming of the event is delayed. Therefore, it is required that a user who does not have specialized knowledge regarding the production of a monitoring system such as a plant operator can easily modify and modify the screen.

  In view of such circumstances, a plant monitoring device capable of additionally displaying process values arranged on one screen on another screen for the purpose of providing a system that can easily modify the monitoring screen, For example, it describes in Unexamined-Japanese-Patent No. 2009-211596 (patent document 1).

  In the plant monitoring apparatus described in Patent Document 1, a process value is added to the screen by selecting a process value by direct selection by a mouse operation or searching by a process value identification symbol and specifying a screen to be displayed. . In addition, the storage location of the process value in the addition destination screen is stored in a dedicated storage means so as to have reproducibility.

  Further, a plant monitoring device that facilitates updating of a database is described in, for example, Japanese Patent Application Laid-Open No. 2010-257097 (Patent Document 2) from the viewpoint of coping with plant renovation and expansion.

  In the plant monitoring apparatus described in Patent Document 2, an identification number is assigned to each of devices constituting the plant, a system to which the device belongs, and a signal acquired from the device, and the devices are managed in association with each other. This makes it possible to easily update the database even when the available signal changes due to renovation or expansion of the plant.

  In the plant monitoring devices described in Patent Documents 1 and 2 described above, the monitoring screen can be easily remodeled, but it is necessary to use a dedicated tool when remodeling the screen. However, there is a problem that screen modification is not easy for a user who does not have sufficient knowledge in using the tool.

  If it demonstrates more concretely, in the plant monitoring apparatus described in patent document 1, the icon displayed on the one screen will be displayed on another screen to the last, and a new icon will not be produced | generated completely. Therefore, a screen modification that collects and displays necessary information according to the situation can be easily performed even by a user who does not have sufficient knowledge, but it is completely new to reflect the modification of equipment such as the addition and deletion of equipment. When performing screen modification that needs to generate an icon, there is a problem that a user who does not have sufficient knowledge cannot easily perform it.

The drawing data and icon information of the system diagram are associated with identification information of the existing system diagram such as a drawing number (system diagram number) of the existing system diagram, for example. Here, the icon information is the same information as the additional icon information 18 and includes at least an icon ID, system diagram number, arrangement location information, and process value ID as icon identification information.

  Therefore, in the plant information display device 10A, by using the identification information (system diagram number) of the existing system diagram as a search key, the drawing data and icon information of the existing system diagram associated with the identification information of the existing system diagram are searched. can do. The existing system diagram information 19 may further include flag information indicating whether or not an additional icon is arranged.

  Subsequently, an operation for generating an additional icon in the plant information display apparatus 10A and an additional icon generation processing step will be described by taking as an example a case where an additional icon is arranged on an image of an existing system diagram.

  FIG. 2 is a schematic diagram showing the additional icon generation screen 20, FIG. 3 is a schematic diagram showing the additional icon information input screen 30, and FIG. 4 is an explanatory diagram for explaining the contents of the additional icon information 18.

  The additional icon generation screen 20 is an input screen for generating an additional icon 24 generated by the screen generation unit 12 that has received the additional icon generation request input from the input unit 14. Information on the additional icon generation screen 20 which is an example of an input screen for generating the additional icon 24 is given from the screen generation means 12 to the input / output device 16 as the output means 15 and displayed.

  In the additional icon generation screen 20, for example, a graphic template area 21 for displaying an image of a graphic (template) 23 to be an additional icon included in the graphic template information 17, and a state in which an additional icon 24 is added (arranged) to the existing system diagram. , That is, a system diagram area 22 for displaying a system diagram during icon addition work. The image of the graphic template area 21 of the additional icon generation screen 20 is generated based on the graphic template information 17, and the image of the system diagram area 22 is generated based on the existing system diagram information 19.

  In the plant information display device 10A, a graphical user interface (GUI) for inputting at least a part of the additional icon information 18 (FIG. 1) generated by the additional icon generating unit 11A is provided as the input unit 14. For example, when an operation (drag and drop operation) for dragging the graphic 23 displayed on the additional icon generation screen 20 and dropping and placing it on the system diagram area 22 is accepted, the additional icon information input screen 30 is displayed. .

  The additional icon information input screen 30 includes, for example, an information display area 31 for displaying detailed information fields 311 to 315 constituting the additional icon information 18 and a system diagram area 22.

  The information display area 31 includes, for example, a system diagram number column 311 which is a column indicating identification information of an existing system diagram to which the additional icon 24 is added (arranged) among information included at least in the additional icon information 18; An icon type field 312 that is a field indicating the type information of the additional icon 24, an icon name field 313 that is a field indicating the name information of the additional icon 24, and an arrangement of the additional icons on the existing system diagram to which the additional icon 24 is to be added. An arrangement location column 314 that is a column indicating location information and a process value ID column 315 that is a column indicating process value ID are provided.

  In the plant information display device 10A, the icon ID corresponding to the figure 23 as an additional icon, the system diagram number column 311, the icon type column 312, the icon name column 313, the arrangement location column 314, and the process value ID column 315 are input. When the acceptance and input are completed, the additional icon generating unit 11A associates the detailed information input in the system diagram number column 311, the icon type column 312, the icon name column 313, the arrangement location column 314, and the process value ID column 315. Thus, additional icon information 18 is generated. Further, the additional icon generation means 11A generates the additional icon 24 in association with the additional icon information 18 and the selected figure 23 (FIG. 2) (FIG. 2).

  Input to each of the columns 311 to 315 can be performed by, for example, manual text input by a user text input operation. In the plant information display device 10A provided with the GUI, the system diagram number column 311, the icon type column 312, and the arrangement location column 314 are automatically input (without manual input of text) by operation via the GUI. Can do.

  The automatic input in the system diagram number column 311, the icon type column 312, and the arrangement location column 314 is performed in response to a drag-and-drop operation of the graphic 23, for example. Regarding the system diagram number column 311, since the existing system diagram in which the graphic 23 is dragged and dropped is a system diagram displayed in the system diagram area 22, an additional icon arrangement is made by referring to the existing system diagram information 19 The system diagram number associated with the existing system diagram in the previous initial state can be identified, and the identified system diagram number can be automatically input to the system diagram number column 311.

  In the icon type column 312, when the graphic type and the additional icon type information are associated with each other, the graphic template information 17 is referred to to associate the graphic type information 312 with the graphic 23 (FIG. 2). Since the icon type can be specified, the specified icon type can be automatically input to the icon type column 312.

  With respect to the arrangement location column 314, the location can be specified by acquiring the coordinates on the system diagram where the graphic 23 is dragged and dropped, so the specified location is automatically input into the arrangement location column 314. be able to.

  Since the icon name column 313 is arbitrary information, the additional icon information 18 is generated even if it is blank (no input). Moreover, the input method to each column 311 to 315 mentioned above is an example, and is not limited to the method mentioned above. For example, the process value ID column 315 may be input by displaying a list of process values managed by the process value management unit 13 and inputting a process value ID that has been selected by the user.

  FIG. 5 is a process flow diagram of a first additional icon generation process performed by the plant information display apparatus 10A that is an example of the plant information display apparatus according to the embodiment of the present invention. A circle A shown in the figure is a connector.

  A 1st additional icon production | generation process process (step S1-step S7) will be started if the plant information display apparatus 10A receives the request | requirement which produces | generates an additional icon (START). In the first additional icon generation processing step, first, the display as the input / output device 16 displays the additional icon generation screen 20 (FIG. 2) generated by the screen generation means 12 and presents it to the user (step S1). .

  Subsequently, when the selection of the figure 23 (FIG. 2) as the additional icon is received from the user (YES in step S2), the display as the input / output device 16 is input with the additional icon information generated by the screen generating means 12. The screen 30 (FIG. 3) is displayed and presented to the user (step S3).

  Subsequently, at least a system diagram number field 311 (FIG. 3), an icon type field 312 (FIG. 3), an arrangement location field 314 (FIG. 3), and a process value ID field 315 (FIG. 3) on the additional icon information input screen 30. Is completed (in the case of YES in step S4), the additional icon generating means 11A generates additional icon information 18 (FIG. 4) (step S5), and further adds the generated additional icon information 18 and the selection received. An additional icon 24 (FIG. 2) is generated in association with the graphic 23 as an icon (step S6).

  Thereafter, when there is a request to end the first additional icon generation processing step due to the fact that the generation of the additional icon 24 has been completed (YES in step S7), the additional icon generation processing step ends (END). ).

  On the other hand, when the figure as the additional icon has not been selected by the user at step S2 (NO at step S2), the process flow of the additional icon generation process returns to step S2 and the figure as the additional icon is selected. The process of step S2 is repeated until it is (selection standby state). In step S4, if at least the system diagram number column 311, the icon type column 312, the arrangement location column 314, and the process value ID column 315 on the additional icon information input screen 30 have not been input (NO in step S4). ), The process flow of the first additional icon generation process returns to step S4, and the process of step S4 is repeated until completion (input completion standby state).

  Furthermore, when step S6 is completed, when there is no request for ending the first additional icon generation processing step (NO in step S7), that is, when the additional icon 24 is still generated, the first The processing flow of the additional icon generation processing step proceeds to step S2, and the processing steps after step S2 are executed.

  The first additional icon generation processing step is an example in which the additional icon generation unit 11A newly generates the additional icon 24 (FIG. 2) (without using the icon on the existing system diagram). However, in the plant information display device 10A described above, the additional icon 24 can be generated using the icon on the existing system diagram.

  FIG. 6 is a process flow diagram of a second additional icon generation process performed by the plant information display apparatus 10A that is an example of the plant information display apparatus according to the embodiment of the present invention. A circle A shown in the figure is a connector.

  The second additional icon generation processing step (FIG. 6) generates an additional icon 24 (FIG. 2) using the icon displayed in the system diagram area 22 (FIG. 2) of the additional icon generation screen 20 (FIG. 2). This is a processing process premised on the case where it is to be performed, and is different from the first additional icon generation processing process (FIG. 5) in that it includes steps S31 to S33 instead of step S2. There is virtually no difference.

  The processing flow of the second additional icon generation processing step proceeds to step S32 when an icon displayed in the system diagram area 22 of the additional icon generation screen 20 is used (YES in step S31). In step S <b> 32, the additional icon generation unit 11 </ b> A acquires the icon information of the icon selected as the additional icon 24 from the screen generation unit 12. The icon information is identified and extracted by the screen generation means 12 searching for icon information included in the existing system diagram information 19 using the icon ID of the selected icon as a search key.

  When step S32 is completed, the screen generation unit 12 calls the existing system diagram in which the additional icon 24 requested by the user is arranged, displays the system diagram in the system diagram area 22 (step S33), and the information display area 31. And the additional icon information input screen 30 (FIG. 3) is displayed (step S34).

  The processing steps after step S4 (step S5 to step S7) in the processing flow of the second additional icon generation processing step are executed in the same manner as the first additional icon generation processing step. At this time, the additional icon information 18 (FIG. 4) is generated using the icon information acquired in step S32. Specifically, the process value ID information input to the icon type column 312 and the process value ID column 315 (FIG. 3) is the icon type information and process value ID information acquired in step S32, respectively. Duplicated and automatically entered.

  When step S6 is completed, if there is no request to end the second additional icon generation processing step (NO in step S7), that is, when the additional icon 24 is still generated, the second addition is performed. The process flow of the icon generation process proceeds to step S31, and the process steps after step S31 are executed.

  In addition, when not using the icon displayed on the system | strain diagram area | region 22 of the additional icon production | generation screen 20 (in the case of NO at step S31), it becomes a process step similar to a 1st additional icon production | generation process process. That is, the process flow of the second additional icon generation process proceeds to step S2 (FIG. 5), and the process steps after step S2 are executed.

  Subsequently, taking as an example the case where an additional icon is arranged on the image of the existing system diagram, plant information display in the plant information display device 10A, that is, a system diagram in which the additional icon is arranged (hereinafter referred to as “remodeled system diagram”) Will be described.

  FIG. 7 is a process flow diagram (sequence chart) of a modified system diagram display process executed by the plant information display apparatus 10A which is an example of the plant information display apparatus according to the embodiment of the present invention.

  As for the processing steps of the modified system diagram display step, steps S11 to S15 are executed in the screen generation means 12, and steps S21 to S25 are executed in the additional icon generation means 11A.

  The modified system diagram display process (step S11 to step S15; step S21 to step S25) is started when the plant information display device 10A receives a display request for the modified system diagram (START).

  The processing steps (steps S11 to S15) on the screen generation unit 12 side of the modified system diagram display processing step are as follows. First, when the screen generation unit 12 receives a display request for a modified system diagram, the existing system diagram that has been requested to display is displayed. Is obtained by accessing the existing system diagram information 19 to generate a first layer image (step S11). In addition, information on the system diagram number, which is identification information of the existing system diagram requested to be displayed, is given, additional icon information of the additional icon arranged in the existing system diagram requested to be displayed, and the shape of the additional icon Is inquired of the additional icon generating means 11A (step S12).

  When the screen generation unit 12 receives the inquiry result (additional icon information of additional icons and graphic image data arranged in the existing system diagram requested to be displayed) from the additional icon generation unit 11A (step S13), the received information Based on, a second layer image is generated (step S14).

  Further, the screen generation means 12 superimposes the generated second layer image with a first layer image that is an image of a layer different from the separately generated second layer image, and generates a display screen signal to be displayed on the display ( Step S15). The generated display screen signal is sent to the input / output device 16, and the display screen (FIG. 7) is displayed on the display as the output means 15.

  On the other hand, the processing steps (step S21 to step S25) on the additional icon generation means 11A side in the modified system diagram display processing step are first activated (step S21), and then enter a standby state for waiting for an inquiry for additional icon information. (Step S22).

  In this standby state, when an inquiry is received from the screen generation means 12 (step S23), the additional icon generation means 11A is the same as the existing system diagram that is inquired using the system diagram number that is the identification information of the existing system diagram as a search key. The additional icon information including the system diagram number and the graphic image data associated with the additional icon information are searched and extracted (step S24).

  After extracting the additional icon information and the image data of the graphic of the additional icon associated with the additional icon information, the additional icon generating unit 11A returns the extraction result to the screen generating unit 12 (step S25). That is, additional icon information and image data of a graphic of an additional icon associated with the additional icon information are sent from the additional icon generation unit 11A to the screen generation unit 12.

  Note that the modified system diagram display processing step described above describes a case in which existing system diagram information 19 that does not have flag information indicating whether or not an additional icon is arranged is referred to. It is not limited. For example, the same processing is executed when referring to the existing system diagram information 19 having flag information indicating whether or not an additional icon is arranged.

  When referring to the existing system diagram information 19 having flag information indicating whether or not an additional icon is arranged, before the step S12 is executed, the existing system diagram for which the screen generating means 12 has requested display. A processing step for checking a flag indicating whether or not an additional icon is arranged is executed. If it is confirmed that an additional icon is arranged in the existing system diagram based on the state of the flag (whether it is standing or not), the processing steps from step S12 to step S15 are executed, while the display request When it is confirmed that no additional icon is arranged in the existing system diagram, the processing steps of Step S12 to Step S15 are omitted.

  FIG. 8 is a partially enlarged view of a system diagram (modified system diagram) in which an additional icon 24 constituting a display screen for displaying plant information of the plant information display device 10A is arranged.

  When the additional icon 24 is arranged in the existing system diagram, the plant information display device 10A displays the system diagram in which the additional icon 24 is additionally arranged in the existing system diagram, that is, the modified system diagram as the input / output device 16 To display. In the modified system diagram illustrated in FIG. 8, a valve icon is added as one of the additional icons 24.

  Here, when an additional icon 24 indicating a valve is selected, a process value ID associated with the additional icon 24 and a process value indicated by the process value ID are displayed. Here, selection is performed by a touch operation or a mouse click. The process value is displayed by, for example, displaying a process value list 37 in which process values are listed in the window 36.

  Further, when a desired process value is selected from the process value list 37 displayed in the window 36, a trend graph 38 of the selected process value is displayed. The broken line 39 indicates the selected process value, and indicates that the process value within the broken line 39 is selected.

  For example, the example shown in FIG. 8 indicates that the process value “exit flow rate” of the process value ID “A01” surrounded by the broken line 39 is selected, and the process value “exit flow rate” is selected by the selection. The trend graph 38 is displayed. In the example shown in FIG. 8, there is one trend graph 38, but a plurality of process value trend graphs 38 may be displayed.

  According to the plant information display device 10A and the plant information display method using the plant information display device 10A, an icon can be easily added (added) to an existing system diagram even when the signal to be acquired increases due to plant renovation or the like. The icon 24 can be additionally placed), and the additionally placed additional icon 24 can be used to monitor the process value associated with the additional icon 24. That is, even a user who does not have sufficient knowledge to use a screen modification and its tool, which has been difficult in the past, can easily modify an image for displaying plant information.

  Moreover, according to the plant information display apparatus 10A and the plant information display method using the plant information display apparatus 10A, the first layer image based on the existing system diagram and the image of the additional icon 24 additionally arranged in the existing system diagram Since the display screen is generated by superimposing the second layer image which is an image of a layer (layer) different from the first layer image, the arrangement of the additional icon 24 constitutes the original display screen The first layer image is not affected. Therefore, even if there is an error in screen modification or modification, the existing system diagram will not be adversely affected.

  In addition, although the plant information display apparatus 10A mentioned above is an example provided with the additional icon production | generation means 11A, the screen production | generation means 12, the process value management means 13, and the input-output device 16, at least an additional icon production | generation means 11A and the screen generation means 12 only need to be provided, and the process value management means 13 and the input / output device 16 are not necessarily provided in the plant information display device 10A itself.

  For example, the process value management means 13 can be omitted if the process value indicated by the process value ID can be acquired from an external device other than the plant information display device 10A such as a process computer. Further, regarding the input / output device 16, information can be input and output between the external device other than the plant information display device 10A such as a monitoring computer terminal device of the process computer and the additional icon generating means 11A and the screen generating means 12. Can be omitted.

  Further, the plant information display device 10A described above will be described with reference to the case where the additional icon generation unit 11A has a function of referring to the graphic template information 17 and giving a graphic image based on the graphic template information 17 to the screen generation unit 12. However, the graphic template information 17 can be obtained by referring to the screen generation means 12. In this case, the screen generation unit 12 may perform the association between the icon ID given by the additional icon generation unit 11A and the image data of the graphic that becomes the additional icon.

[Second Embodiment]
FIG. 9 is a schematic diagram showing a configuration of a plant information display device 10B as an example of a plant information display device according to the second embodiment of the present invention, and FIG. 10 is an explanatory diagram for explaining the contents of the status information 41.

  The plant information display device 10B has, for example, an additional icon generation unit 11B instead of the additional icon generation unit 11A with respect to the plant information display device 10A, and status information 41 and an accessible storage unit or storage medium. The difference is that the status display setting information 43 is further held and the display screen is generated using the status information 41 and the status display setting information 43, but there is no substantial difference in other points. Therefore, in the description of the present embodiment, the difference will be mainly described, and the description overlapping with the above-described embodiment will be omitted.

  The plant information display device 10B is a device that acquires a process signal of a plant to be monitored and displays plant information based on the acquired process signal. For example, an additional icon generation unit 11B, a screen generation unit 12, The process value management means 13 and the input / output device 16 as the input means 14 and the output means 15 are provided. Further, the plant information display device 10B holds graphic template information 17, additional icon information 18, existing system diagram information 19, status information 41, and status display setting information 43 in accessible storage means or storage media.

And a function of providing information 41.

  The status information 41 includes information indicating the state of the plant equipment indicated by the additional icon 24 (FIG. 2), and is associated with the icon ID of the additional icon 24. The information indicating the status of the plant equipment includes, for example, information on the type of equipment classified according to whether the target plant equipment is existing or new, and whether the target plant equipment is in an operating state or in a stopped state. Information on the operation status classified according to whether it exists or the like is included (FIG. 10).

  The status display setting information 43 is information in which information indicating the status of the plant equipment in the status information 41 is displayed and a screen is generated. If the status information 41 shown in FIG. 10 is described as an example, the status display setting information 43 includes information on the display style of the additional icon 24 corresponding to whether the plant equipment is existing or newly installed, and the operation of the plant equipment. And information on the display style of the additional icon 24 corresponding to whether it is in the middle or stopped. Here, the display style of the additional icon 24 includes, for example, the display color, line type, line thickness, or lighting state of the additional icon 24.

  In the plant information display device 10B configured as described above, an additional icon generation processing step (first and second additional icon generation processing steps) for generating the additional icon 24 can be executed in the same manner as the plant information display device 10A. .

  On the other hand, regarding the plant information display in the plant information display device 10B, that is, the plant information display by the modified system diagram, the status of the plant equipment in the status information 41 is shown with respect to the plant information display in the plant information display device 10A. The difference is that the information is reflected and the additional icon 24 is displayed in a display format corresponding to the information indicating the state of the plant equipment.

  In the plant information display device 10B, the additional icon generation unit 11B manages the status information 41. The additional icon generation unit 11B inputs, for example, device type information and operation status information according to a user in advance or automatically.

  The automatic input of the device type information can be executed based on, for example, whether the above-described additional icon generation processing step is the first additional icon generation processing step or the second additional icon generation processing step. Specifically, if it is the first additional icon generation processing step, it is determined that the plant equipment is not in the existing system diagram, and is “newly established”. If it is the second additional icon generation processing step, it exists in the existing system diagram. It is determined that the plant equipment is “existing”.

  The automatic input of the operation status information is, for example, receiving on / off information of the plant equipment from the process value management means 13 at an arbitrary timing, and determining whether to operate or stop based on the received on / off information of the plant equipment. It can be executed by inputting new information or updating existing information.

  When the display request for the modified system diagram is received from the user, the additional icon generation unit 11B uses the system diagram number, which is identification information of the existing system diagram, as a search key, and the same system as the existing system diagram inquired from the screen generation unit 12 The additional icon information 18 including the figure number and the image data of the graphic 23 (FIG. 2) associated with the additional icon information are searched and extracted. Further, the additional icon generation means 11B searches and extracts the status information of the plant equipment using the icon ID of the extracted additional icon 24 (FIG. 2) as a search key.

  The additional icon generation unit 11B includes additional icon information 18, image data of the graphic 23 of the additional icon 24 associated with the additional icon information 18, and a plant associated with the icon ID which is identification information of the additional icon 24. When the status information of the device is extracted, the extraction result is returned to the screen generation means 12 as an inquiry result.

  On the other hand, when the screen generation means 12 receives the inquiry result from the additional icon generation means 11B, the second layer image is generated based on the received information, and is superimposed on the separately generated first layer image and displayed on the display. A display screen signal is generated. At this time, the screen generation unit 12 refers to the status display setting information 43, selects a display format according to the display format information corresponding to the status information received from the additional icon generation unit 11B, and outputs a signal on the display screen. Generate.

  According to the plant information display device 10B and the plant information display method using the plant information display device 10B, the plant information display method 10A and the plant information display method using the plant information display device 10A have the same effects as the plant equipment. Therefore, the plant information can be displayed by reflecting the status information of the plant equipment, so that the icon of the plant equipment in a state that matches the requested condition can be highlighted. As a result, the line of sight of the plant operator (user) can be guided to useful parameters, and the monitoring work can be made more efficient.

  In the plant information display device 10B and the plant information display method using the plant information display device 10B described above, the status information 41 and the additional icon information 18 constitute independent information, but the status information 41 is added. It may be included in the icon information 18.

  If there are two types of device type information in the status information 41, a flag indicating the device type can be set in the additional icon information 18, and the device type information with the flag set can be omitted from the status information 41. . Similarly, when there are two types of operation status information, a flag indicating the operation status can be set in the additional icon information 18 and the flag-set operation status information can be omitted from the status information 41. If the flag indicating the device type and the flag indicating the operation status are set in the additional icon information 18, the device type and the operation status are distinguished based on whether or not the flag set in the additional icon information 18 is set. It is because it can do.

  Furthermore, in the example of the status information 41 shown in FIG. 10, the device type information and the operation status information are shown in two cases, respectively, but may be three or more. For example, the operation status may be indicated in three ways: “normal” indicating a normal driving state, “abnormal” indicating a state in which an abnormality is detected, and “stop” indicating a stop state.

[Third Embodiment]
FIG. 11 is a schematic diagram illustrating a configuration of a plant information display device 10C which is an example of a plant information display device according to the third embodiment of the present invention.

  For example, the plant information display device 10C retains raster image data 46, which is raster format image data, instead of the existing system diagram information 19 including vector format image data, with respect to the plant information display device 10A. The first layer image is different from the vector format image instead of the raster format image, but there is no substantial difference in other points. Therefore, in the description of the present embodiment, the difference will be mainly described, and the description overlapping with the description in the above-described embodiment will be omitted.

  The plant information display device 10C includes, for example, an additional icon generation unit 11A, a screen generation unit 12, a process value management unit 13, an input unit 14 and an input / output device 16 as an output unit 15.

  For example, the plant information display device 10D has a non-graphic object such as a hand-drawn symbol (hereinafter referred to as “object”) in addition to the graphic 23 (FIG. 2) with respect to the plant information display device 10A. The difference is in the point that the object generation unit 51 to be generated is further included, the point that the object information 52 is further held in the accessible storage unit or storage medium, and the processing content of the screen generation unit 12, but the other points are substantially different. There is no difference. Therefore, in the description of the present embodiment, the difference will be mainly described, and the description overlapping with the description in the above-described embodiment will be omitted.

  The plant information display device 10D switches on and off the function of generating an object, the function of arranging the object on the existing system diagram, and the display of the object on the monitoring screen, with respect to the plant information display device 10A. For example, additional icon generation means 11A, screen generation means 12, process value management means 13, input / output device 16 as input means 14 and output means 15, and object generation. Means 51.

  The plant information display device 10D holds graphic template information 17, additional icon information 18, existing system diagram information 19, and object information 52 in an accessible storage means or storage medium.

  The object generation means 51 has a function of generating image data of the object and a function of holding the image data of the object in association with the object identification information. For example, when there is an object hand-drawn and input from the input / output device 16, the object generation unit 51 recognizes the object input by hand-drawn as an object and generates image data of the recognized object. The generated image data of the object is held in storage means or a storage medium accessible as object information 52.

  The object information 52 includes at least image data of the object and is held in association with the object identification information. By associating with the identification information of the object, a desired object can be searched using the identification information as a search key, and management of the object becomes easy.

That is, an image such as an existing system diagram is set as a first layer image, an image received from the additional icon generating unit 11A is set as a second layer image, and an image of an object received from the object generating unit 51 is set as a third layer image and superposed. A screen is generated.

  Further, in the plant information display device 10D, the screen generation unit 12 has a function of switching whether or not to use the third layer image when generating a monitoring screen in accordance with an input command. Therefore, the plant information display device 10D can generate a monitoring screen for displaying an object or a monitoring screen for hiding an object, depending on whether or not an object display request is present.

  In the plant information display device 10D configured as described above, in addition to the add icon 24 (FIG. 2), an object that can be additionally arranged on the image of the existing system diagram can be generated. Moreover, in the plant information display apparatus 10D, an object additionally arranged on the image of the existing system diagram can be displayed or hidden. For example, when a note composed of characters is an object, the note (object) can be displayed as necessary.

  An operation for generating an object in the plant information display device 10D and an object generation processing step will be described.

  As an operation for generating an object, the user operates the input unit 14 to request the screen generation unit 12 to generate an object. When the screen generation unit 12 is requested to generate an object, for example, a screen for receiving an input of an object is displayed on the output unit 15 such as a display of the input / output device 16.

  Subsequently, the user inputs an object by manual input or the like. When the input of the object is completed, a screen for confirming the registration of the object is displayed, and the user specifies that the object is registered. When the operation for registering the object is completed, all operations for generating the object are completed.

  On the other hand, in the object generation processing step executed by the plant information display device 10D, when an operation for generating an object is received, a screen for receiving an input of the object is displayed on the output unit 15.

  Subsequently, when the input operation of the object is completed, a screen for confirming the object registration is displayed, and permission for object registration by the user is accepted. When permission for object registration by the user is received, the image data of the object is stored in a storage unit or storage medium that is associated with the object identification information and accessible as the object information 52.

  The modified system diagram display processing step in the plant information display device 10D is the same as the modified system diagram display processing step in the plant information display device 10A. The point that the (three-layer image) is also generated is different from the point that the generated third-layer image is also superimposed, but the other points are not substantially different.

  Thus, according to the plant information display method using the plant information display device 10D and the plant information display device 10D, the same effects as the plant information display method using the plant information display device 10A and the plant information display device 10A are obtained. .

  Further, in the plant information display device 10D and the plant information display method using the plant information display device 10D, in addition to the add icon 24 (FIG. 2), an object that can be additionally arranged on an image such as an existing system diagram is generated. can do. Therefore, even when an unexpected event occurs, it is possible to hand-draw precautions and communication items for monitoring work and display them as objects on the monitoring screen. Becomes easy. That is, when an unexpected event occurs, a flexible and quick response can be taken.

  Furthermore, in the plant information display device 10D and the plant information display method using the plant information display device 10D, an object image is an image of a monitoring target (first layer image) such as an existing system diagram or an image (second image) of an additional icon 24. Since the image is superimposed after being generated as an image (third layer image) of a layer different from the layer image), the image of the object can be displayed or hidden in the monitoring screen. Therefore, it is possible to further increase the amount of information to be displayed on one monitoring screen and the degree of freedom.

  The plant information display device 10D described above further includes an object generation unit 51 with respect to the plant information display device 10A, and describes an example in which the object information 52 is further held in an accessible storage unit or storage medium. However, the plant information display device 10D can adopt the same configuration for plant information display devices other than the plant information display device 10A such as the plant information display device 10B.

  Moreover, although the plant information display apparatus 10D mentioned above is demonstrated as an apparatus which performs the process until it produces | generates an object, Furthermore, the additional icon 24 (FIG. 2) which linked | related additional icon information 18 with the produced | generated object is shown. It can also be set as the apparatus which performs the process to produce | generate. That is, in addition to the graphic 23 (FIG. 2) prepared as a template, the plant information display device 10 </ b> D that can generate the additional icon 24 by associating the additional icon information 18 with the object generated by the object generating unit 51 can be used.

  When the plant information display device 10D that can generate the additional icon 24 by associating the additional icon information 18 with the object, the additional icon generation unit 11D with some functions added to the additional icon generation unit 11A may be applied. Necessary. The additional icon generation unit 11D provides a function of providing image data of the object as a target to be associated with the additional icon generation unit 11A when the additional icon 24 is generated, and the selected object and the additional icon information. 18 is further added to the function of generating the additional icon 24 in association with.

  In the plant information display device 10D capable of generating the additional icon 24 by associating the additional icon information 18 with the object, the object is provided as an option as a target to be associated with the additional icon information 18 when the additional icon 24 (FIG. 2) is generated. More specifically, an image of an object to be the additional icon 24 included in the object information 52 is displayed on the additional icon generation screen 20 (FIG. 2).

  It should be noted that the object image can be displayed in any manner as long as an operation (drag and drop operation) for dropping and placing the object to be added icon 24 is displayed in system diagram area 22 (FIG. 2). It is. For example, it may be displayed together with the image of the graphic 23 in the graphic template region 21 or may be displayed in a state that can be switched to the image of the graphic 23.

  Further, when the additional icon 24 is generated by associating the additional icon information 18 with the object, after the additional icon 24 is generated, the additional icon is generated in the image data of the object selected as the object to be the additional icon 24 (FIG. 2). Information of the icon ID given when the means 11D generates the additional icon 24 is further associated. That is, the object information 52 is held in a state in which at least the image data of the object, the identification information of the object, and the icon ID are associated with each other.

  By such association with the icon ID, in the plant information display device 10D, even when the additional icon information 18 is associated with the object and the additional icon 24 is generated, the screen generation unit 12 obtains necessary information from the additional icon generation unit 11D. It is possible to extract and extract the additional icon 24 necessary when generating the display screen.

[Fifth Embodiment]
