[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is a method for checking process conditions in various plants such as power plants and FA plants.
The present invention relates to a device for displaying on display means such as T.

0002

[Prior art] To monitor and control plant operation,
The function of displaying the status of various processes in the plant on a display device such as a CRT as necessary is an essential function of a plant monitoring/control device.

[0003] When the plant is installed in a foreign country, the display on the process display device is usually in the language of the country concerned. However, when the above-mentioned plant monitoring and control equipment (including process display equipment) is handled by multiple operators speaking different languages, displaying information in a single language may cause inconvenience to communication between the operators. be. For example, when exporting plant monitoring and control equipment manufactured in a first country to a second country that uses a different language, the first In some cases, engineers in one country and engineers in a second country (the user country) use the same screen to handle control equipment, but if the display is only in a single language, plant monitoring and control equipment It is insufficient to teach detailed operating methods.

Conventionally, in plant monitoring and control systems, a process display device that takes the above points into consideration has not been realized, and communication between operators using the process display device has not been sufficiently smooth.

On the other hand, various devices are known that display predetermined messages in multiple languages. For example, there are known cash registers or electronic fare scales that display the same message in multiple languages alternately or simultaneously so that people from different countries can understand the same message (Japanese Patent Laid-Open No. 63
-132396, JP-A-63-121717). Additionally, there is a known device in which messages with the same content expressed in multiple languages are stored in memory, and one of the messages is selected from the outside and displayed (Japanese Patent Laid-Open No. 62
-63310, JP-A-61-157919).

[0006]

[Problems to be Solved by the Invention] All of the above-mentioned conventional techniques display a predetermined fixed message in a plurality of different languages simultaneously, alternately, or by selection from the outside. , such as process display devices in plant monitoring and control equipment, can display process conditions that can change from moment to moment in multiple languages.
No consideration is given to displaying on different display devices. Therefore, it cannot be applied to a process display device in a plant as described above.

An object of the present invention is to provide a process status display device that can display the same process status on different display devices in different languages depending on changes in the process status.

Another object of the present invention is to automatically display, on the same screen, a common display of process data, etc. that is used universally regardless of language, and a language-specific display of process states, etc., which are expressed in different forms depending on the language. It is an object of the present invention to provide a process status display device that can be edited and displayed.

[0009]

[Means for Solving the Problems] In order to achieve the above object, the present invention is characterized by a plant database that detects and stores the process status in a plant, and a system that uses symbols and the like that are commonly used regardless of the language used. a common display output database for storing; a language display output database for storing information expressing the same content in different languages; switching means for selecting the plurality of language display output databases; and a selected language display output. A process status display device includes a plant information editing processing means for editing the contents of a database, the plant database, and the common display output database on a predetermined screen, and a display means for displaying the edited screen in a predetermined language.

0010

According to the present invention, the plant information editing processing means edits the process status, which can change from time to time, to be displayed on the screen in a selected language together with a fixed message that does not depend on the process status. Then, screens with the same meaning and content are displayed on the plurality of display devices in different languages. Therefore, a plurality of operators using different languages can each view a display screen with the same meaning and content displayed in their respective languages, and through this, communication between the two operators can be carried out effectively.

[0011]

[Example] Examples will be explained below. FIG. 1 shows the functional configuration of the plant monitoring device of this embodiment. In Figure 1,
A plurality of display devices 11 to 1n such as a CRT and a plurality of input devices 21 to 2n such as a keyboard are installed. The display devices 11 to 1n have a function of displaying the status of each part of the plant on a screen, and the input devices 21 to 2n have a function of selecting screen display contents.

Reference numeral 1 denotes a computer system, which has various functions necessary for plant monitoring. In Figure 1, among them,
Only features directly related to the invention are described. 3 is a screen display control means, and display devices 11 to 1n (hereinafter referred to as 1
(Represented by 1) controls the screen display on the screen. Reference numeral 5 denotes an input control means, which controls instruction input by an operator from input devices 21 to 2n (hereinafter represented by 21). 33 is a plant input/output device, which controls signals from various detectors installed in the plant 32 to detect the status of each part of the plant, and input/output of signals to each part of the plant or the plant control device. Reference numeral 9 indicates a series of processing groups (software) for displaying predetermined contents on the screen based on instruction input from the input device 21 and input signals from the plant 32, and 10 indicates a series of processing groups used for the processing. indicates a table or a group of files.

The plant data that has passed through the plant input/output device 33 is input into a plant data table 35 by a plant input/output processing 34. The operator's instruction input via the input device 21 and the input control means 5 is transmitted to the display plant information editing process 30 by the display screen request process 20. In addition, among the instructions input by the operator, regarding the designation of the language type used in the screen display, a switch position switching process 6 is used to select which of the display output databases 81 to 8n for each language to be used, which will be described later. Activate 7. The display plant information editing process 30 creates content to be displayed on the display device 11 based on the data from the display screen request process 20 and the table group 10 (details will be described later using FIG. 3). The created content is displayed on the screen by the screen display control means 3 and the display device 11 through the display output processing 4.

Next, examples of screen displays resulting from the various processes described above will be explained with reference to FIG. In FIG. 2, 200 is an example of a screen displayed on the display device 11, and shows an example of displaying the status of equipment such as various valves and pumps in a plant.

[0015] This screen example has six columns of displays 201 to 206. Column 201 is the number of each line displayed on the screen,
In the example of FIG. 2, it can be seen that numbers 17 to 32 are displayed. Column 203 is a data name given to each object of state display such as various equipment in the plant (this is a process variable, hereinafter simply referred to as a variable). Column 202 is data name 2
03, and these are identification numbers according to international conventions for identifying data names. Column 204 indicates the operation mode when the data name is equipment. That is, when the device is in automatic mode, "AUT" is displayed as shown in the figure, and when it is in manual mode, "MAN" is displayed. Column 2
05 displays the current status of the equipment etc. represented by the data name shown in column 203. For example, it indicates whether a valve is "open" or "closed," and a pump indicates whether it is running or stopped. Column 206 shows the status of output signals from the computer to each device.

Among the above columns 201 to 206, column 201
indicates a number, and column 202 displays an identification number according to international conventions, which is a common display in any language. However, columns 203 to 206 indicate device names and their statuses, and their notation differs depending on the language of each country. Therefore, a display device that only displays information in a single language will display content that cannot be deciphered by some operators, causing inconvenience in monitoring the status of the plant. In this embodiment, as shown in FIG. 1, a plurality of display devices of the same type are provided,
By displaying the content as shown in Figure 2 in the language selected by each operator, and by arranging them in close proximity, multiple operators using different languages can display the same content in the same place. This allows users to monitor the ever-changing plant status while looking at the screens (in different languages). Furthermore, in the plant status monitoring that is the object of the present invention, the display in each language is not just a fixed message, but one that changes depending on the plant status (column 2 in Figure 2).
04-206). In this embodiment, in view of these points,
Edit the screen contents as described below.

FIG. 3 shows details of the display plant information editing process 30 shown in FIG. 1. Further, FIGS. 4 to 7 show the contents of various table/file groups 10 used in the editing process. First, an overview of each table and file will be explained. FIG. 4 shows the configuration of the screen display specification table 40. Figure 2
As can be seen from the comparison, each item displayed on the screen is configured to correspond to each row and column. FIG. 5 shows the configuration of the common display data table 50. In this embodiment, the tag number is stored. FIG. 6 shows the structure of the plant data table 60. In this embodiment, for each variable, input data 61, output data 62, mode data 63
These data are updated by the plant input/output processing 34 according to changes in the plant status. and,
According to these data contents (specifically, numbers 0, 1, 2, and 3), display information tables 110 to 110 to be described later are displayed.
The display contents stored in 120 are selected.

FIG. 7 shows the structure of the language-specific display output data table 8. It has an equipment name table 100, plant input/output data display information tables 110 to 113, and a plant mode data display information table 120 for each language. FIG. 7 shows an example of Japanese as an example of language A.

Next, the editing process for the screen shown in FIG. 2 will be explained with reference to FIG. First, a line-by-line counter i is set to 1 (corresponding to the first line on the screen) (301). This results in
Since the variable number in the i (=1) row of the screen display specification table 40 is 17, this is set as the row number j=17 (302). Next, a counter k indicating the data item number (column number) in each column of the table 40 is set to "2", which is the first processing item number (303). Next, processing type data in the column indicated by the counter k in the i-th row of the table 40 is retrieved. For example, i=1, k=2
If so, it can be seen from FIG. 4 that the processing type data of the corresponding item is "1" (304). The subsequent processing is determined by this processing type. First, when the processing type is "0", a blank field is displayed and a blank code is displayed and output (3050). If the processing type is "1", the contents of j (variable number) are set in R indicating the arrangement order (record number) in the table. This results in outputting the contents of the table as is (3051). When the processing type is "2", the value of input data 61 of the data in record Noj of table 60 is set to R (3
052). If the processing type is "3", the value of the output data 62 of the data in record Noj of the table 60 is set to R (3053). When the processing type is "4", the value of mode data 63 of the data of record Noj of table 60 is set to R (3054).

Next, the table number of row i and column k of the table 40 is retrieved (306). Next, the information of the record indicated by R in the table No. retrieved in step 306 is retrieved. At this time, table number is 100
, 110 to 113, or 120, the SW (switch) 3072 sets the table group number indicating which language the table group belongs to (307,
3071). Next, the information extracted in step 308 is output to a display device.

The above is a series of steps, and the same type of processing is then performed for other columns and rows. That is, the column counter k is incremented by 1 and the process moves to the next column. the result,
When k>6, the process moves to step 310, and when k≦6, the process moves to step 304. Finally, it is determined whether all rows have been completed (310). In other words, add 1 to the row counter j,
When j>(maximum row), the process ends.

The correspondence between the above processing steps and the screen display in FIG. 2 is as follows (taking the top line display in FIG. 2 as an example).

[0023] Step 301: i=1 Step 302: j=17 Step 303: k=2 Step 304: A value of "1" is extracted.

[0024] Step 305: Branch to step 3051.

Step 3051: R=j=17 Step 306: Table No.=50 Step 30
7,308: Arrangement order of tag numbers in table 50 R = 1
Information on "LV0017" indicated by 7 is extracted and output for display.

[0026] Step 309: If k=3, proceed to step 304.

[0027] Step 304: Processing type = 1 Step 305: Branch to step 3051.

Step 3051: R=17 Step 306: Table No.=100 Step 3
07,308: "Tank received HCV" is taken out and displayed and output. Step 309: k=4, and the process returns to step 304.

[0029] Step 304: Processing type = 4 Step 305: Branch to step 3054.

Step 3054: Record j (=17
) is 2, so R=2.

Step 306: Table No.=120 Step 3
07,308: Record No. of language A table 120
The content "AUT" of 2 is extracted and output for display.

Step 306: k=5, and the process returns to step 304.

[0033] Step 304: Processing type = 2 Step 305: Branch to step 3052.

Step 3052: Record No. of table 60 = 17
Since the input data of is 0, 0 is set in R.

Steps 307 and 308: The information “closed” in record 0 of the language A table 110 is extracted and output for display.

Step 309: k=6, and the process returns to step 304.

[0037] Step 304: Processing type = 3 Step 305: Branch to step 3053.

Step 3053: Record No. of table 60 = 17
Since the output data of is 0, R=0.

Step 306: Table No.=111 Step 3
07,308: Record number of table 111 for language A
0 information "stop" is extracted and output for display.

Step 309: k=7, and the process moves to step 310.

Step 310: i=2, and the process returns to step 302.

As described above, in this embodiment, the process status is displayed on the screen in the specified language in accordance with the change in the process status. By preparing two display devices and specifying different languages for each display device, the same content can be displayed in each language while responding to changes in the process status.

The above embodiment displays the process status of the actual plant 32, but if a simulated plant and simulated plant data are used instead of the actual plant, it can also be applied to a simulator for plant operation training. .

[0044]

According to the present invention, the process state can be written in a predetermined language in response to changes in the process state. Therefore, it is possible to write in the language used by the operator who monitors the process. In particular, since a plurality of operators using different languages can interact while looking at screens with the same semantic content (different notation), it is effective for education and guidance regarding process monitoring.
