(Prior Art) Conventionally, information regarding alarms in actual plants such as nuclear power plants has been documented, and a copy of the information is always kept near the plant operation port. When an abnormality occurs in the actual plant, a plant operator searches the document for alarm information to deal with the abnormality, displays it, recognizes the alarm information, and deals with the abnormality in the actual plant.

(￥P, the problem that Ming is trying to solve) Warning information requires a huge amount of information, especially in large plants such as nuclear power plants, and the amount of documents recording the warning information is also enormous. Therefore, when an alarm occurs, searching for information related to that alarm from a huge amount of documents requires a lot of effort.
Moreover, since a quick response cannot be made, it is practically difficult to respond to urgent warnings. In order to solve this difficulty, various proposals have been made for devices that automatically display the content of alarm information when an alarm occurs.

However, in order to automatically display the contents of alarm information, when a plurality of alarms occur at the same time, it is necessary to determine which alarm information should be displayed first and to selectively display it. These judgments and selections complicate the processing procedure, complicate the display device, make it difficult to process quickly, and make the device expensive. Furthermore, if this judgment and selection is left to the plant operator, there are problems in that the method for specifying alarms is complicated, and that it takes time to specify alarm names because they are too long.

In addition, in order to respond accurately and quickly to abnormalities in actual plants, it is necessary to individually produce alarm information for each plant to make it highly useful, which raises the problem of high production costs. be.

The present invention has been made in consideration of the above circumstances, and its purpose is to easily and quickly display alarm information based on judgment and selection by the user or operator when an alarm occurs, thereby allowing the user or operator to process the alarm.

Next, the operation of the above embodiment will be explained along the flowchart of FIG. 3.

If an abnormality occurs in the actual plant during plant operation, an alarm a is issued. When an alarm a occurs, the digital signal interface device 10 inputs the alarm a via the process computer 20 and outputs an alarm signal to the alarm panel display module 11. The alarm panel display module 11 inputs this alarm signal and outputs an alarm panel position display signal C.
Output. The CRT display 12 to which this alarm panel position display signal C is input displays the position of the alarm panel 30 corresponding to alarm a on a simulated figure of the plant operation console displayed on the screen in advance.

The images on the CRT display 120 are, for example, as shown in FIG. 4, and the position of the alarm panel 30 corresponding to the alarm is clearly indicated by changing colors such as red. When multiple alarms a are issued, multiple alarm panels 30 are clearly displayed.

When the position of the alarm panel 30 is specified, the plant operator recognizes this and moves the mouse 13. mouse 13
When the mouse 13 moves, a position designation signal d is outputted from the mouse 13, and the information display module 14 inputting this position designation signal d outputs a screen position designation signal e to the CRT display 12. The CRT display 12 inputs this screen position designation signal e and moves the mouse cursor 31 on the screen.

This mouse cursor 31 moves on the screen in response to one movement of the mouse 13. The plant operator moves the mouse 13 held in his hand while looking at the mouse cursor 31 on the screen to move the mouse cursor 31 to an arbitrary position on the CRT display 12, thereby moving the mouse cursor 31 to an arbitrary position on the screen. Can be specified.

When multiple alarms a occur and multiple alarm panels 30 are displayed on the CRT display 12, a plant operator judges the importance and urgency of the alarm a and displays one alarm panel 30. Select it and specify its position.

In this manner, when a specific position of the alarm panel 30 on the CRT display 12 is specified by operating the mouse 13, a simulated figure of the alarm panel 30 as shown in FIG. 5 is displayed on the CRT display 12.

The simulated figure of this alarm panel 30 is configured in a grid shape,
Inside each frame is a warning window 32.

When a plant operator selects one of the alarm windows 32 and operates the mouse 13 to designate its position with the mouse cursor 31, the position designation signal output from the mouse 13 is simultaneously input to the DTFI alarm designation module 15. Then, an alarm designation signal f is output from the alarm designation module 15.

When the alarm designation signal f is output, the search module 16 inputs it, searches the database 3 for alarm information corresponding to the above designation, and outputs the alarm alarm signal q. The information display module 14 inputs this alarm alarm signal q and outputs an alarm information display signal. The CRT display 12 to which this alarm information display signal is input displays alarm information on its screen.

The alarm information is as shown in FIG. 6, for example. This alarm information includes an alarm name 35, a detector name 36, a detector setting value 37, a related document sheet number 38, a processing procedure 39, a work selection menu 40, and the like. If you want to know more about the processing history, specify "Processed fat layer" in the work selection menu 40 with the mouse cursor 31, and the display screen will change.
A processing history 41 as shown in FIG. 7 is displayed. When the user wants to view the next page of the processing history 41, the next page is displayed by specifying "next page" on the work selection menu 40 with the mouse cursor 31. The format of the alarm information shown in FIGS. 6 and 7 above is just an example, and various aI! formats can be used depending on the plant. is possible.

In this way, plant operators view the CRT display 12.
Recognize the alarm information displayed on the screen and quickly process the alarm that occurs.

Roughly speaking, when a plant operator wants to change the contents of alarm information stored in the database 3, he operates the mouse 13 as described above to display the alarm information he wants to change on the CRT display 12, and then presses the mouse cursor. In step 31, addition, deletion, modification, etc. of the work selection menu 4o is specified.

Thereafter, the plant operator operates the keyboard 5 to input new information. When the keyboard 5 is operated, an alarm input signal i is output from the keyboard 5. The screen editing module 17a inputs this information input signal 1 and outputs an alarm signal k to the database management module 17b. The database management module 17b, which has received this information signal k, outputs an information change signal j to the database 3. This information change signal j is input to the database 3, and the contents of the alarm information stored therein are changed.

For example, it is possible to modify the detector setting value 37 and the related sheet number 38, or to add a new processing history 41.

In the above embodiment, when multiple alarms occur, the plant operator U judges the importance and urgency of the alarm and selects the alarm information to be displayed. No equipment is required, it is economical, and rapid processing is possible.

In addition, when plant operators select and specify alarms, there is no need to input long alarm names, etc.
Since it is only necessary to specify the screen position of the CRT display 12 by using the above command, it is possible to quickly respond to the alarm.

Furthermore, since the contents of the W report information stored in the database 3 can be changed freely, it can be applied to various types of brands, and there is no need to design and produce it independently for each plant, making it economical. It has the effect of being highly sexual.

Further, in the above embodiment, the alarm signal is received and accepted;
Since it is configured to be clearly displayed on the CRT display 12,
This also has the effect that the position of the alarm panel 30 where the alarm has been generated becomes clear, and a more prompt response becomes possible.

[Effects of the Invention] As explained above, the alarm processing support device according to the present invention has a screen position designation system in which a user or an operator operates to designate a position on the screen, and a and an alarm information display system that searches alarm information corresponding to the specification from alarm information stored in the database in advance and displays it on the screen according to the position specification.
