  The present invention relates to an instrumentation operator's console drawing method and a plant monitoring and control system, and more particularly to drawing a graphic screen used for a plant control apparatus for performing feedback control, sequence control, process state monitoring, etc. The present invention relates to an instrumentation operator console drawing method and a plant monitoring control system suitable for what is to be performed.

  2. Description of the Related Art Conventionally, a graphic screen drawing device used in a process monitoring and control system draws a screen by a combination of a graphic display form (expression pattern) and process data (display data), as can be seen in Japanese Patent Application Laid-Open No. H10-228707.

  There are various display patterns for graphic display, such as numerical expression, graph expression, color change expression, video expression, etc., and register where to place these expression patterns on the screen. By registering the process data capture destination (data terminal name) to be combined, the graphic screen is created.

  The information registered for drawing is stored as a file. The graphic screen display device analyzes this file, collects data from the process data import destination (data terminal name), and displays it in combination. The graphic screen display is realized. In addition, the graphic screen that is drawn in this way is recreated while changing the display form by limiting the amount of information according to the purpose.

JP 2000-81870 A

  By the way, although the information necessary for the above-mentioned drawing can only be registered, the contents registered once need to be individually called and confirmed. Further, it is possible to search the registered contents and partially pick up, but the target content is one item of the target, and the drawing efficiency is poor. Furthermore, although it is possible to display and print a list of all registered contents, there is a problem that it is difficult to understand the association with the actual screen.

  The present invention has been made in view of the above points, and the object of the present invention is not only to improve the drawing efficiency, but also to make it easy to understand the association between registration information and the actual screen, resulting in engineering efficiency. It is to provide an instrumentation operator's console capable of improving the performance.

  In order to achieve the above object, the instrumentation operator's console drawing method of the present invention is connected to a plant control device comprising a processing device and a process input / output interface via a communication line, and the control state of the plant control device is When the screen used for operation monitoring displayed on the graphic screen of the instrumentation operator's console for operation monitoring is drawn according to the purpose and purpose, the basic screen is drawn, and components are selected and added from there. Thus, a related screen configuration is created, and the constituent elements are linked and displayed.

  In order to achieve the above object, a plant monitoring control system of the present invention includes a plant control device comprising a processing device and a process input / output interface, and an instrumentation operator console for operation monitoring of the control state of the plant control device. And the communication line connecting these devices, the instrumentation operator's console displays a basic screen for drawing the screen used for operation monitoring displayed on the graphic screen according to the purpose and purpose. It is characterized by creating a related screen composition by drawing, selecting and adding a component from there, and displaying the component by linking it.

  In general, a graphic screen drawing device used in a plant monitoring control system draws a screen by a combination of a graphic display form (expression pattern) and a process data (display data) acquisition destination. Process data includes numerical data (analog data) such as temperature and flow rate, and ON-OFF data (digital data) indicating the state. The type of data used in the display form (expression pattern) is determined for each display form. Yes.

  Focusing on this point, when a display form (expression pattern) is registered, a dummy capture destination (dummy terminal) can be automatically assigned.

  Specifically, it is possible to assign analog data 1, analog data 2, digital data 1, and analog data 2 in the order of registration. In addition, a dummy capture destination (dummy terminal) is automatically allocated temporarily. Eventually, it is necessary to assign the necessary collected data to the dummy terminals that are automatically assigned, but there is no problem even if the dummy terminals are left at the stage of creating a drawing image or a component.

  These components can be managed as one package by examining and arranging attributes of related data. If detailed drawing data is created by concentrating data first, level control of these data enables multi-step drawing according to the amount of information from the detailed screen to the simple screen. It is possible to have detailed information related to the interior of the wax.

  As means, it is possible to select necessary information from the registration information on the detailed screen and to have the auxiliary information for each level, and it can be easily realized by making the selection method into a table format or the like. In addition, the drawing information is displayed only on the display position and display form on the screen and can have an image, but detailed information on the component (data attribute and variable information specifications) can be called up. There is no choice but to confirm. However, by associating the display portion on the screen with the display specification and displaying a combination of a plurality of pieces of information, it is possible to easily confirm the registered contents and perform highly efficient additional changes.

  According to the present invention, not only can the drawing efficiency be improved, but the association between the registration information and the actual screen can be easily understood, and as a result, the engineering efficiency can be improved.

  The instrumentation operator console drawing method and plant monitoring control system of the present invention will be described below based on the illustrated embodiments. In each figure, the same symbols are used for the same components.

  FIG. 1 shows a configuration example of a plant monitoring control system, FIGS. 2 and 3 show graphic screen drawing examples, FIG. 4 shows graphic screen property-related display examples, FIG. 5 shows graphic screen property-related printing examples, FIG. 6 is a configuration example of display according to level, FIG. 7 is a configuration example of package information, FIG. 8 is a processing flow of graphic screen drawing, FIG. 9 is a configuration example of graphic screen association processing, and FIG. FIG. 11 shows an example of a graphic screen related display process, FIG. 12 shows an example of a package display process flow and package display information, and FIG. 13 shows an example of package display information and a graphic screen registration file.

  In FIG. 1, reference numerals 10 and 12 denote plant control apparatuses, and the plant control apparatuses 10 and 12 are connected to operator consoles 50 and 52 via a communication line 40. Of these, the plant control device 10 detects the flow rate of two fluids flowing into the tank 20, for example, the oil flow rate by the flow meters 22 and 24 that are sensors, and the detection signals from the flow meters 22 and 24 are taken in. . When the total amount of oil flowing into the tank 20 detected by the flow meters 22 and 24 reaches a predetermined amount, a control signal is output to the process valve 26, the process valve 26 is opened, and the oil flows out from the tank 20 to the tank 30. Let

  The plant control apparatus 10 is controlled to close the process valve 26 after a predetermined time after opening the process valve 26. Further, a flow meter 28 is also provided at the subsequent stage of the process valve 26, and the flow rate of oil flowing from the tank 20 to the tank 30 is measured and taken into the plant control device 10. On the other hand, the plant control device 12 grasps the status of the plant connected to the rear stage of the tank 30 and controls the process valves 32 and 34 to perform manual control. The graphic screen 60 displays data displayed on the display of the operator's console 50 in accordance with the plant configuration and the like.

  In this way, the screen used for operation monitoring is the graphic screen 60 using the plant image. Naturally, such a screen must be drawn as one of the plant designs.

  The general graphic screen 60 performs registration as shown in FIG. That is, as shown in FIG. 2, expression form registration information examples 110, 120, and 130 are registered in the graphic screen drawing 100. Specifically, in the expression form registration information example 110, a data acquisition destination (temporary terminal A001), an expression form (bar graph), coordinates, colors, a graph shape, and the like are registered. Similarly, in the expression form registration information example 120, data acquisition destination (provisional terminal A002), expression form (numerical value display), coordinates, color, phone scale conversion, and the like are registered. In the expression form registration information example 130, The data acquisition destination (provisional terminal D001), expression form (button display), coordinates, color, pixel number, etc. are registered. These are drawn in order, and the target graphic screen 60 is drawn and constructed.

  In this embodiment, the data capture destination at the time of drawing registration is automatically assigned to the first analog data (A001) or the first digital data (D001), so that the data capture destination is not conscious. It is possible to draw and register. When the process data capture destination is determined, the process information capture destination (data capture destination) can be officially allocated by calling the input of the process information capture destination information input / assignment 150. At this time, if an input destination such as the input device display 160 on the process information capture destination information input / assignment display is selected, the representation form configuration display unit arranged on the graphic screen also displays the process information capture destination on the graphic screen drawing. An information input / assignment position display 170 is shown. In addition, the representation form configuration display unit arranged on the graphic screen is selected, and the process information capture destination information input indicating that the process information capture destination information input / allocation position display 170 on the graphic screen is selected is input. It is also possible to indicate the input device display 160 on the corresponding process information capture destination information input / allocation display on the allocation 150.

  In the graphic drawing system in recent years, as shown in FIG. 3, the graphic screen 200 is selected from the icon group which is the drawing component element display prepared in the expression form registration icon group 210, and the component elements are arranged. In many cases, detailed information is used as a property, and necessary items are registered in the property display registration 220.

  In the case of such a method, a graphic screen can be created in advance of an image as a drawing screen, which is efficient in newly registering.

  However, in this case, multiple properties cannot be confirmed simultaneously. FIG. 4 shows an example in which a window for displaying a plurality of component element properties is prepared and displayed in association with each other.

  As shown in the figure, first, the graphic screen 250 is displayed, and each component is clicked (designated) using a pointing device such as a mouse in the component display mode to display the property display section of the graphic screen property 260. It is additionally displayed.

  The mutual association is expressed by automatically assigning a leader line and a number like reference items 251 and 261, reference items 252 and 262, reference items 253 and 263, and reference items 254 and 264. In addition, a comment can be added to the comment input unit 255 at an arbitrary position.

  When printing the displayed contents as a document, a method of printing the graphic screen 250 and the graphic screen property 260 separately, and printing on the graphic screen document output unit 280 as one document as shown in FIG. There is a way to output.

  In the case of outputting as one document shown in FIG. 5, the properties of the property print 283 are collectively arranged, and an easy-to-view document is drawn by directly drawing (associating display) with individual components on the graphic drawing part document 284. Can be created.

  In this way, it is possible to associate the constituent elements with the configuration information (properties) and easily display the display parts in association with each other. Based on these technologies, the concept of packaging registration information is shown below.

  As shown in FIG. 6, one process data relates to data for controlling a plant in addition to data measured simply. For example, when temperature control is taken, in addition to the measured value, a target value for temperature increase, an alarm boundary value of actual measurement values, control data for temperature increase (operation value), and the like are associated. A data display configuration as shown in a display example 601 of level 3 in FIG. 6 is one example.

  In this way, in order to create a simple screen from information (display components) registered as a detailed screen, a configuration as shown in the display example 602 of level 2 is used, or a simplified level 1 such as a summary screen is used. A display example 603 and a recent icon 604 for development on a graphical screen are created in various ways on the display, but it is not efficient to register and create each one.

  Actually, the display examples of the level 3 display example 601, the level 2 display example 602, the level 1 display example 603, and the expansion icon 604 are different, but the internal data is the level 3 display example 601. Can be aggregated into the data used. This can be expressed by betting the configuration as shown in FIG.

  As shown in FIG. 7, the display of the display example 601 of the level 3 can be expressed by the level 3 display configuration example 611 on the left side of the table format of the package information configuration example 610 if it is defined as level 3 expression. The expression of the level 3 display configuration example 611 is not significantly different from the expression format previously shown in FIGS. Rather, it can be said that the expression format is followed.

  By selecting necessary items from the expression format of the level 3 display configuration example 611 and having accompanying information, the level 2 display configuration example 612, the level 1 display configuration example 613, and the icon display configuration example 614 are displayed in a table format. It can be packaged in a unified manner from the detailed screen to the simple screen. By specifying the level with this package information, it is possible to create a simple screen with detailed information inside.

  Based on the above, next, the processing of the graphic screen drawing device will be described based on FIG.

  As shown in FIG. 8, first, in step 301, it is determined whether the drawing input is completed or continued. If continuation is selected, an expression form to be drawn is selected in step 302. In step 303, registration information (coordinates, colors, shapes, etc.) other than the process information fetch destination is input. When these inputs are completed, dummy terminals are automatically assigned in step 305. As this method, for example, an analog terminal and a digital terminal are automatically assigned in the order of registration according to the application. Further, the input of the process information fetch destination is registered at step 307. This procedure is repeated, and if the drawing is finally finished, the registered contents are stored in the graphic screen registration file 320 at step 308.

  Next, the configuration of the graphic screen registration file 320 will be described with reference to FIG.

  As shown in FIG. 9, the graphic screen registration file 320 includes an expression form registration information section 400 and a process information capture destination information section 410. By adopting such a configuration, the display unique information and the variable part of the data are displayed. Separation can be achieved.

  The expression form registration information section 400 stores expression form registration information contents 401 in the order of registration, and dummy terminals are registered in the expression form registration information contents 401. Further, in the process information capture destination information unit 410, the association between the dummy terminal and the actual process information capture destination information content 411 is registered in the registration order, and the representation form registration information and the process information of the representation form registration information unit 400 are registered. The process information capture destination information in the capture destination information unit 410 is associated via the dummy terminal 330.

  By passing through the dummy terminal 330 in this way, a flexible screen configuration can be packaged, and a part that is converted into a subroutine and given as a parameter is used as a process information capture destination that is specific registration information. It becomes possible to define.

  In addition, the association file 340, which is a component of the present embodiment, records related information 1, 2 to n, and each piece of related information is associated registration NO (expression form registration information NO and expression form type), The associated information (coordinates of expression form, property display coordinates) and incidental information can be used as unique information. It is realizable by setting it as the above structures.

  FIG. 10 shows a case where the association file 340 is actually registered from the graphic screen.

  As shown in FIG. 10, first, in step 501, it is determined whether the association is completed. If the association is completed, the association contents of the association file 340 are stored in the file (step 506). If the association is continued, a component is selected in step 502 using a pointing device such as a mouse. In step 503, registration information is selected from the selected components and selected, and in step 504, display / printing positions are automatically assigned. Further, if necessary, incidental information is set in step 505. Since the association file can be created in this way, the association can be displayed.

  Therefore, as described above, by preparing the graphic screen registration file 320 and the association file 340, it is possible to perform display including related information on the display device.

  Further, as shown in FIG. 11, in order to display the graphic screen on the graphic screen display device 520, the expression form registration information of the graphic screen registration file 320 is edited with the component property 530, and the dummy terminal 330 is displayed with the display process 510. The data is taken out from and displayed. At the time of the test, it is possible to set data from the document data 540 to the dummy terminal 330 to create a document including the test data.

  The processing method described above is also effective for a packaged configuration. The relationship between the package display information file and display processing is shown in FIG. The process of the package display information file 800 obtained by simplifying the file of the above-described package display information configuration example 610 will be described with reference to FIG.

  As shown in the figure, first, the package display information file 800 is referred from the top, and it is determined in step 701 whether the package information is completed. While there is information, the processing of steps 702 to 706 is performed, and the process of returning to step 701 is repeated. Since the information is stored in the order of the contents registered at level 3, it is determined at step 702 whether the target level is valid information (necessary). If it is valid information, the data collection destination information is fetched and edited in step 703 as target data editing. Further, the display attribute is edited in step 704 from the drawing command. If this information has additional information (step 705), this information is also edited in step 706. The processing so far is the level data extraction processing, and the actual display processing is performed in the processing after step 707.

  First, among the information edited in step 704, a fixed attribute (not refreshed display) is displayed in step 707. Further, target data (refresh data) is collected in step 708 based on the data collection destination information edited in step 703. The collected data is displayed in step 709 according to the information edited in step 704 or step 706. Basically, a delay process is inserted in step 711 to ensure a refresh cycle, but by repeating steps 708 to 711, continuous refresh display is possible. If there is an end request due to an operation such as screen switching, the determination is made at step 710 and the process ends.

  In this way, the package information can also be displayed and expanded. As shown in FIG. 13, the package display information file 800 can be operated and managed by associating with the package management file 810. Furthermore, it can be easily associated with the graphic screen registration file 320 shown above, and it can be seen that this embodiment can be realized.

  As described above, by dividing the graphic form registration file into the expression form registration information part and the process information capture destination information part, it is possible to make parts and package. In addition, management and confirmation can be performed by displaying and printing out these pieces of information.

  In the graphic screen drawing in the process monitoring control system, the purpose is to draw, and the detailed information of the components at the time of registration is only managed as the drawing information for each item. This information can be easily confirmed by packaging and managing the level, or by calling the drawing screen with a single touch and managing the internal data so that it can be automatically laid out and displayed and printed on the screen margin. Detailed information can be loaded, and it can be managed as a highly efficient document.

  These pieces of association information are not necessary for normal operation monitoring, but can be used by creating an additional call when creating a test document, and are always present as internal information, so that they can be easily read and edited. In addition, since the process data information can be incorporated as necessary, the efficiency of the drawing test is improved.

  By using the present embodiment described above, the following effects can be obtained. In other words, in the field of process control monitoring system, create related information for detailed screens and detailed information of components (specifications of data attributes and variable information) for drawing graphic screens for plant operation monitoring in advance, From there, selecting and adding simple screens (divided into levels) according to need in a table format etc. makes it possible to easily draw and display the screens at each level, enabling efficient drawing. At the same time, the registered contents can be visually confirmed, and detailed information can be referred to on a simple screen. Furthermore, registration and change can be easily performed, and by incorporating comments and the like into the document as additional information, it is possible to improve the efficiency of graphic screen drawing for process monitoring and to reduce costs.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described. Further, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of each embodiment.
