An embodiment of the present invention will be described below using a thermal power plant as an example. FIG. 2 shows a thermal power plant and its alarm monitoring system. Heat exchanger 1, valve 2, turbine 3, generator 4, condenser 5 installed in the plant. Cause contacts indicating the alarm state from each part of the pump 6 are taken into a field installation board 7 installed at the field. Then, the status can be displayed on the field-installed panel 7 and the cause can be checked.6Furthermore, these contacts are taken into the monitoring panel 8, aggregated, and displayed on the corresponding alarm window 9. Alarm windows 9 cannot be provided corresponding to all the individual contact points due to space constraints and the operator's monitoring ability, and usually 300 to 500 windows are provided. On the other hand, all causative contacts are connected to the monitoring computer 11 via the process input/output device 1o from the field installation panel 7.
is input to.

Here, the processing in the monitoring computer 11 will be explained using FIG. 3. The process signal input processing section 30 periodically scans information from each part of the plant, and outputs contact signals from l and o.
As a bit signal, analog signals such as temperature and pressure are usually converted from 0 to 20
It is taken in as a value of 00 digits. The data conversion alarm processing section 31 converts these imported values into data in engineering units in the case of analog signals, checks alarm limit values, and checks whether the contact signal alarm is in an alarm state. I do. The results of this check are stored in plant status storage 32 along with the processed process values. On the other hand, when a request is made to display an alarm window from the keyboard 12 (see FIG. 2) attached to the display device or other operating instruments, the request is judged by the judgment section 33 that accepts the request.

The request content is stored in the request content information storage section 34 and transmitted to the alarm state determination section 35.

The alarm state determination unit 35 extracts the identification number group of plant information corresponding to the alarm window from the alarm window and alarm cause correspondence information storage unit 36, and stores the process information and cause contact information corresponding to the identification number in the plant state storage unit 32.

The alarm block/alarm window information editing unit 37 takes in the request content from the request content information storage unit 34, edits the display information of any of the initial screen display, alarm cause window display, and alarm window scroll display, and edits the edited information. are sent to the initial screen display section 38, alarm cause window display section 39, and alarm window scroll section 40, respectively.

Next, in FIG. 0, the configuration of the alarm window display screen will be explained using FIG. 1, in which numbers 1 to 8 and arrows are displayed as soft keys 13 at the bottom of the display screen. 1~
The number 8 actually indicates the name of the alarm window block display section 14 displayed above it, as shown in FIG. 5, for example. Here, the soft key 13 refers to a first button that displays a name indicating a function on the screen instead of a hard key.
In the example shown in the figure, ten hard keys or a touch screen can be used to request various functions. Using the softkeys 13, the ten hardkeys allow nearly unlimited requests by switching the display.

The following example will be explained using a touch screen that allows various requests to be made by touching the screen. Similar functions can be achieved using cursor keys, mouse, etc. other than the touch screen. Further, the arrow 4- is a soft key for scrolling the alarm window display area. Above the soft keys 13, there is disposed an alarm window block display section 14 that displays the entire alarm window as a block according to the shape of the alarm window 9 provided on the actual monitoring panel. Each block of the alarm window block display section 14 is
As shown in the figure, it consists of multiple meshes (the minimum unit of character display representing one character), and each mesh has an alarm window 9.
It corresponds to Then, the alarm window block display section 14
An alarm window display section 15 is arranged at the upper part of the alarm window display section 15, and the name of the alarm window is displayed on each block of this alarm window display section 15. Therefore, in the alarm window block display section 14.

The position within the entire alarm window is recognized, and the content of the alarm is recognized from the alarm display section 15 above it.

Details of the initial display will be explained with reference to FIG.

Here, figures and characters are usually displayed in green.

In the case of initial display, the information in the displayable portion is edited from the left of the leftmost block and displayed at the top as an alarm item display. On the alarm window block display section 14, the area where the alarm window is displayed is shown filled in blue so that the upper part where the alarm is displayed can be easily recognized.

Further, a window in an alarm state is displayed as a red mesh on the alarm window block display section 14, and the window name and frame are displayed in red on the alarm window display section 15, so that the alarm location can be easily identified. From the initial display screen.

If you want to display another window, press the alarm window block display section 14.
By touching , softkeys, or scroll keys,
This is possible by moving the display area on the alarm window block display section 14.

Next, the alarm cause window display will be explained. Fifth
The figure shows an example of a window display screen. Alarm window display section 15
If you touch the alarm window whose cause you want to know above, that part will turn yellow and at the same time the cause and cause information corresponding to that alarm window will be displayed in a window 16.

The number of factors varies depending on the alarm window, and if the information cannot be displayed in the window area, all information can be viewed by scrolling. For this reason, a scroll touch area and a scroll bar are also displayed in the window section to indicate which part of all factors the displayed part corresponds to. Furthermore, the window can be moved to other positions so that areas hidden by the window can be easily seen. FIG. 6 shows the flow of window display processing. First, in step 600, when the alarm window is touched, the computer reads the coordinates of the touched part, and in step 601, based on these coordinates and the currently displayed alarm window information, the alarm window corresponding to the touched part is Determine the number. Then, in steps 602 and 603, the cause group is indexed from the alarm window and alarm cause correspondence information storage section based on the alarm window number, and the alarm state is fetched. Next, in step 604, the area to be displayed as a window is determined.

Depending on whether there is an alarm touched on the upper or lower half of the alarm window display section, a window is displayed on the lower half or the upper half, respectively. Finally, in step 605, after determining the alarm area, a window display is output on the display screen.

Next, the scroll display of the alarm window will be explained.

FIG. 7 shows a scroll display method.

In the figure, it is assumed that the second block from the left is currently being displayed from the left end. When you touch the right shift key, the display area is cut out and displayed as shown in the middle row. As a result, it appears as if the alarm window has moved to the left on the screen.In a normal display device, it is difficult to store all information in the frame memory of the display device control unit due to memory capacity constraints. be. In this embodiment, data is written to the frame memory block by block. Therefore, in the case of scrolling within the same block, all information is already in the frame memory, so there is no need to newly write information from the computer side. When moving to the next block, all the next block information is written into the frame memory, and then the display area is cut out and displayed. The processing flow is shown in FIG. 8. First, in step 800, the scroll direction is determined, and in step 801, it is determined whether the movement is within the same block. Then, if the movement is within the same block, the process proceeds to step 803, and if the movement is not within the same block, the alarm display window information in the adjacent block is written in the frame in step 802. Further, in step 803, a display area is cut out from the frame, and in step 804, an alarm window is displayed at the top of the display screen.

As above, the alarm window display based on a request has been explained, but it is also possible to automatically display the alarm window display without making a request when an alarm occurs. When an alarm occurs, the alarm state determining section 35 shown in FIG. 3 is automatically activated and displays an alarm window area corresponding to the location where the alarm is occurring.

If multiple alarms occur, follow the flow shown in Figure 9.
Select the display area. First, in step 900, the alarm state of the alarm window is captured. Next, in step 901, the number of alarm generation windows is counted for each block, and in step 9
In step 02, select the block with the largest count number.

Then, in step 903, the display area is shifted to the right one window at a time within the block, and the number of alarm windows is counted for each case until the right end of the display area reaches the right side of the block. Among these, the case with the largest count is determined as the display area in step 904, and the determined display area is displayed in step 905.

Although only the alarm window information display has been described above, as another embodiment, when an alarm occurs, it would be convenient if a system diagram related to the cause and basis of the alarm is displayed. Therefore, if a related system diagram is predetermined for each alarm window, the system diagram can be prepared as a soft key, and by touching this soft key, related information can be displayed in the window.

Further, FIG. 10 shows an example in which a partial area with an alarm window is displayed together with a scrollper. The scroll bar 20 indicates to which part of the entire alarm window the displayed alarm window corresponds in the vertical and horizontal directions.

By touching the scroll bar 20 and moving it vertically and horizontally, any alarm window can be displayed. Furthermore, by displaying in red the portion corresponding to the alarm window where the alarm is occurring on the scroll bar display area, it is possible to easily reach the display location of the alarm window where the alarm is occurring.

〔Effect of the invention〕

As explained above, according to the present invention, not only the state of the alarm window but also the cause thereof can be easily grasped on the display screen, so that prompt response can be taken when an alarm occurs.

In addition, since the monitoring information is called up to the person rather than having the person go to the monitoring window on the monitoring panel, highly reliable human-centered man-machine communication can be realized.

Furthermore, since the alarm window can be used as a substitute for monitoring, it is possible to eliminate the monitoring panel in the future.
