Abstract

PURPOSE:To enable an operator to confirm the document in accordance with their degrees of necessity by displaying the documents on a screen in the order of higher importance among those produced alarms and outputting the documents of lower importance to a printer. CONSTITUTION:A document output means 5 takes out the importance and the alarm level of an alarm input point at the head of a document output list 4a to compare the alarm level with the importance which is under output to an image processing CRTC. Then it is decided based on the result of comparison whether a document should be outputted to the image processing CRT or a printer D. Thus the document data is taken out of a document table 5a and outputted with the document number stored in the list 4a used as an index. As a result, even a document of low importance is never disused and outputted to the printer D and an operator can confirm the document of the relevant alarm as necessary.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention provides an explanation system (hereinafter referred to as a document) that describes the cause of failure and countermeasures when an alarm occurs during plant operation. 6. Related to Driving Support Device Displayed on Screen Display Device (Prior Art) A conventional example of this type of driving support device is shown in FIG.

The status of the plant A is input to the alarm monitoring means 2 of the operation support device 1 through the process input/output device B.

The alarm monitoring means 2 receives signals (hereinafter referred to as "signals") sent from various parts of the plant A via the process input/output device B.

9.Next, the alarm monitoring means 2 sequentially inputs plant signals (called "plant signals"), detects whether or not an alarm has occurred, and sets an alarm level according to the plant signal at that time if an alarm is present. In the occurrence list 2a, the input point number of the plant signal that caused the alarm (a number to identify the location where the plant signal that caused the alarm was generated, hereinafter referred to as the alarm input point number) and the alarm level are displayed. The documents are written in the order in which they are confirmed, and the document selection means 3 is notified.

The document selection means 3 sequentially extracts the alarm input point number and alarm level from the alarm occurrence list 2a.
Next, using the alarm input number as an index, the importance is taken out from the importance table 3a, and the document number is taken out from the alarm cause table 3b', stored in the alarm information list 3c, and the document output adjustment means 4 is notified.

The document output adjustment means 4 uses its alarm information list 3c.
The alarm importance level is compared with the importance level stored in the document output list 4a, and if the importance level of the alarm to be updated this time is high, the importance level of that alarm,
Update alarm data consisting of an alarm level and a document number to an appropriate position in the document output list 4a,
Subsequent alarm data is shifted and notified to the document output means 5.

The document output means 5 is a document output list 4a.
By indexing the document number and referring to the data table 5a, data for document output is created and output to a screen display device such as an image processing CRTC.

(Problem M to be Solved by the Invention) However, in the above-mentioned conventional device, when multiple document screens regarding alarms are outputted to the image processing CRTC by the document output means 5 in a short period of time, There was a problem in which even though the document screen was output, the document screen for the next alarm was output immediately, creating a situation where the operator could not confirm it. As a result, there is a problem in that when the alarm generation finally subsides, the document screen output to the image processing CRTC remains for the alarm of the lowest importance.

In addition, in the above conventional device, image processing CRTC
Because the document output to the system uses one screen for each alarm, the amount of data that can be uploaded is limited. It took time to search through a wide range of materials and conduct research, and there was a high possibility of making mistakes.

Furthermore, since it was not possible to store documents related to alarms that occurred, there were other problems such as the time it took to collect back-up data for cause analysis at a later date.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a plant operation support system that allows operators to easily confirm information they wish to confirm without requiring operators to search for relevant materials that are deemed necessary.

[Structure of the Invention] (Means for Solving the Problems) Signals from each part of the plant are received via the process input/output device WB, and it is detected whether or not an alarm has occurred, and the alarm input point number ( an alarm monitoring means for writing an identification number of the place where the alarm occurred) and an alarm level (indicating the magnitude of the generated alarm signal) into an alarm occurrence list and a historical buffer; and the alarm input point of the alarm occurrence list or the historical buffer. Using the number as an index, the importance table (a table in which the importance level corresponding to the alarm input point is set), the alarm factor table (
A document structure table (corresponding to the index indicating the document group) and a document structure table (corresponding to the index indicating the document group), each having an index indicating a document group that describes the cause of failure of the alarm input point and its countermeasure method, corresponding to the alarm input point number. document selection means for writing the importance level, the alarm level, and the document number of the document into an alarm information list; document output adjusting means for editing the document output list by comparing the importance level and alarm level within the document output list (consisting of the document number, the alarm level, and the document number), and determining the priority order of the documents of output information; According to the list, the documents for which the alarm occurs are retrieved from the document data table (a table in which document data is set corresponding to the document I-number), and multiple documents are output to the screen display device in descending order of priority, and the others are output to the printer. and an interaction input means for activating the document selection means to output details of necessary warning documents to the screen display device based on instructions from the input device.

(Function) Documents related to alarms with high current levels of importance and alarm level are always output to the screen display device via the document output means, and the remaining documents are output to the planter.

In addition, the dialog input means has a function that allows detailed documents from the second stage of the document group related to the cause of the alarm to be output at will by pressing a specific key on the input device, so that the operator can obtain detailed information about the alarm. can be quickly and accurately confirmed.

In addition, since the alarm input point number and alarm level are stored in the historical buffer in the order in which the alarm occurred, the situation of the alarm occurrence can be output later by going backwards to past data using dialogue, which can be used as a great clue for cause analysis. .

(Embodiment) FIG. 1 shows a configuration diagram of a plant operation support device according to an embodiment of the present invention.

In the figure, the state of plant A is process input/output device B.
The signal is input to the alarm monitoring means 2 of the driving support device 1 through.

The alarm monitoring means 2 reads plant signals sent from each part of Process'XA via the process input/output device B, detects the presence or absence of an alarm, and as shown in FIGS. 2 and 3,
If an alarm occurs, the alarm input point number 2a for that alarm
For alarms that have returned from the alarm state, the alarm input point number 2a□ and alarm level 2a2 are set to O in the alarm occurrence list 2a shown in Figure 2 and the historical information shown in Figure 3. The document is stored in the buffer 2b and the document selection means 3 is activated. At this time g
The alarms are written in the alarm list 2a in the order in which alarm states or alarm returns are detected.

The document selection means 3 selects the second document from the alarm occurrence list 2a.
The alarm input point number 2a1 and alarm level 2a for one alarm input point shown in the figure are taken out in order. Next, using the alarm input point number 2a□ as an index, the importance level 3a1 is extracted from the importance level table 3a shown in FIG.
From the alarm factor table 3b shown in the figure, the index 3b1 of the document group that explains the factors related to alarm generation is taken out, and the index 3b□ of the doki comment group is used to create the first row in the document structure table 3d shown in FIG. Extract the document number 3d1 of the summary document.

Note that the importance level table 3a and the alarm factor table 3 are
In b, information for all alarm input points is stored in order of alarm input points. In addition, in the document structure table 3d, for each index corresponding to each alarm input point, starting from the first stage that shows the cause of the failure and an outline of its countermeasures, and then the nth stage that shows the specific details. A number is set for each document up to. Then, if only the index of the document group corresponding to the alarm input point number is specified and no document number is specified, the document number in the first stage indicating the outline of the document group is extracted.

As described above, the importance level 3a1 extracted using the alarm input point number 2a1 in the alarm occurrence list za as an index, the alarm level 2a in the alarm occurrence list 2a, and the document number 3d1 are stored in the alarm information list 3c shown in FIG. Then, the document output adjusting means 4 is activated and processing moves to the next item in the alarm occurrence list 2a.

Therefore, the alarm information list 3c includes the alarm occurrence list 2a.
Information is written to the alarm input point number 2811@ extracted from.

The document output adjusting means 4 extracts the importance level 3a and the alarm level 2a from the alarm information list 3c, and outputs the 8th alarm level.
Importance level 3a in the document output list 4a shown in the figure,
and alarm level 2a for each alarm input point, edit the document output list 4a while determining the output priority order of documents related to the alarm input points taken out from the alarm information list 3c, and then edit the document output list 4a. Start 5.

This operation is repeated until the alarm information list 3c is empty. At this point, the document output list 4a is arranged in descending order of importance level 3a and alarm level 2a.

The document output means 5 is a document output list 4a.
Importance level 3a and alarm level 28□ related to the first alarm input point are extracted and compared with importance level 3=1 currently being output to the image processing CRTC and alarm level 2a. Based on the comparison result here, it is determined whether the output light of the document is to be image processing CRTC or printer D, and the document number 3d in the document output list 4a is determined.
Using l as an index, document data 5a□ is taken out from document data table 5a shown in FIG. 9 and output.

Note that when a document with alarm level 2a and O is retrieved from the document output list 4a, the document corresponding to importance level 3a and document number 3b is deleted from the image processing CRTC and the document output list is It will also be deleted from 4a.

Then, the document newly placed in the fifth position is displayed on the image processing CRTC.

Further, the document output means 5 compares the importance level 3a and alarm level 2a in the document output list 4a with the importance level 3a□ and alarm level 2a of the document regarding the alarm currently displayed on the image processing CRT C. , importance level 3a in document output list 4a
, is higher, document output list 4
The data in a is displayed on the image processing CRTC, and the document that has been displayed on the image processing CRTC is output to printer D. Conversely, if the importance level 3a1 of image processing CRTC is higher, the document is output. Documents to be output in list 4a are output to printer D. or.

When both documents have the same importance level 3a.

The alarm levels are compared and the document with the highest alarm level is output to the image processing CRTC in descending order of alarm level 2a and so on.

The dialogue input means 6 receives input data such as page forward/backward, alarm input point number, output request to printer D, etc. from the input device E, and updates the input information table 6a shown in FIG. 10. At this time, the document selection means 3 selects the input information 6
a, and unconditionally outputs it to the image processing CRTC as the alarm input point with the highest degree of importance.

With the above configuration, in order to output documents of alarms with high importance, the document selection means 3 uses the importance table 3a based on the alarm input point number 2a newly written in the alarm occurrence list 2a by the alarm monitoring means 2. From importance level 3a
At this point, if the alarm has returned from the alarm state, document output is canceled or image processing is performed on the CRT.
Since it is necessary to erase C, it is also necessary to determine the importance level 3a for the alarm input point whose alarm level is O.

In addition, the index 3b1 of the document group related to the cause of the alarm is extracted and used as an index. The document number 3d of the summary document is extracted as the first stage document from the used document structure table 3d, and
The alarm information list 3c is updated together with the importance level 3a1 and the alarm level 2a, and the document output adjustment means 4 is activated.

The document output adjustment means 4 compares the importance level 3a in the alarm information list 3c with the importance level 3al in the document output list 4a one by one, and outputs a document related to the alarm input point extracted from the alarm information list 3c. Document output list 4 while determining priorities
At this time, if the importance level 3a is the same, the alarm level 2a is compared, and the output priority is determined.

If the importance level 3a and the alarm level 2a are both the same, the document output list 4a is updated immediately after the same data, and the document output means 5 is activated every time the processing for -alarm input points is completed.

For alarm input points with alarm level 2a and O, the importance level 3a and document number 3d1 are compared with the alarm information list 3c and document output list 4a, respectively, and if the same one is found, the data is is deleted from the document output list 4a.

The document output means 5 is a document output list 48
Severity level 3a and alarm level 2a from the beginning.

The output priority order of the document currently being displayed on the image processing CRTC is determined using the same method as the document output adjusting means 4. image processing CRT
Assuming that five documents can be displayed in a superimposed manner on C, if the document retrieved from the document output list 4a is within the fifth document with the highest importance level 3a among those currently generating an alarm, it will be displayed according to the output priority order. Image processing Changes the CRTC display. At this time, the overflowing document is automatically output to printer D. Conversely, if it is not in the top five, it is output to printer D as is.

Note that when a document with alarm level 2a of 0 is retrieved from the document output list 4a, the document corresponding to importance level 3a and document number 3di is deleted from the image processing CRTC and also retrieved from the document output list 4a. delete.

Then, the document newly placed in the fifth position is displayed on the image processing CRTC.

Next, in order to perform a dialog operation, the dialog input means 6 is used.

When a specific key on input device E is pressed.

Information corresponding to the specific key, for example, information regarding forward/backward forwarding of the document or an output request for historical information, etc., is generated as the input information table 6a.
Then, the document output means 5 or the document selection means 3 is activated.

When the document selection means 3 is activated by the dialog input means 6, a document number is designated to display the detailed document desired to be displayed, depending on the selection and pressing conditions of a specific key. For example, if a specific key is pressed to request detailed information of the first document displayed on the image processing CRTC, each press of that specific key will cause the details of the document displayed on the image processing CRTC to be By changing the numbers in sequence, detailed documents are displayed in sequence. Here, the specific keys are the first and second keys of the document on the image processing CRTC.
th...Key 1 for each specific key corresponding to the 5th
, key 2 . . . key 5. Also, regarding the document currently being displayed, for example, if you want to go backwards to the first stage document when the nth document is being displayed, you can set a specific key that allows you to go backwards and display the detailed document. Bye.

Further, when the document selection means 3 is activated by the dialog input means 6, the document selection means 3 checks the input information 6a1 in the input information table 6a, and sends historical information to the printer D according to the procedure described above. It can also be output.

It is preferable that the display of the detailed document by the dialog input means 6 is always outputted as the first document of the image processing CRT C. At this time, when the timing to display the document has come due to the operation as the alarm monitoring means 2, there is a conflict. When doing so, it is preferable to give priority to the processing function of the dialog input means 6 and output it to the image processing CRT C.

In addition, if there is a request for outputting historical information by pressing a specific key selection valve of the input device E from dialogue, the document selection means 3 stores the historical information in the historical buffer 2.
Based on the alarm input point number 2a and the alarm level 2a in b, it is also possible to output all documents regarding alarms that have occurred or returned to the printer to the printer.

As described above, even if a plurality of alarms occur in a short period of time, documents of the five alarms with the highest degree of importance are always displayed on the image processing CRTC, and the operator is promptly notified. Further, documents regarding alarms of low importance are outputted to the printer D without being discarded, and the operator can reconfirm the alarm documents through interactive operations as necessary. and,
The dialog input means 6 inputs the detailed document of the document corresponding to the currently displayed alarm by dialog operation to the first stage, second stage, etc. each time a specific key of the input device is selected and pressed.
...With the n-th stage and 0 or more capable of displaying detailed documents, detailed contents of the generated alarm can be quickly and accurately notified to the operator, so that actions can be taken quickly and accurately in response to the alarm.

[Effects of the Invention] As explained above, according to the present invention, documents can be displayed on the screen display device in order of importance among the generated alarms, so that the alarm monitoring efficiency and judgment work of the operator can be improved. I can figure it out. At this time, documents etc. of low importance are output to the printer, so that the operator can check them as necessary. In addition, through interactive operations, operators can reconfirm alarm documents that have already been output as necessary, and can also display detailed documents, allowing them to quickly and accurately obtain detailed information about alarms that have occurred. It is also possible to quickly and accurately take action in response to an alarm.
