BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant monitoring device for monitoring process information in a nuclear power plant or the like.

[0002]

2. Description of the Related Art A conventional plant monitoring apparatus monitors a plant by displaying a marker as one of the process data monitoring methods. This shows the state of process values by reading two process data from the plant and displaying a marker on the graph. When displaying a marker, two types of process data are read for each marker, the process data is converted into coordinate values, and when a plurality of markers are displayed simultaneously, the markers are displayed in the order of reading.

FIG. 18 shows a conventional example of such a plant monitoring device. As shown in the figure, the plant monitoring device
It comprises a display device 1, a display control unit 2, a marker creation unit 3, a process database 4 and a process input unit 5. Further, the display control unit 2 includes a display database 21 and a display control processing unit 22, and the marker creation unit 3 includes a marker creation processing unit 31, a fixed marker database 32, and a variable marker database 33. In addition, the process input unit 5 has a function of creating and updating the process database 4 (see FIG. 19B) from the process input at a constant cycle.

The fixed marker database 32 includes input point numbers required for display, upper and lower limits of full span of display, number of full span dots, number of input point indicating alarm information of process data, and determination of marker display color. A database showing the symbol types of data and markers (Fig. 19 (a)
The reference value is the reference data) and the marker data creation processing unit 31 reads the input point number from the fixed marker database 32 and inputs the process value from the process database 4 using the input point number of the process value. The input process value is converted into X and Y coordinate values by the number of dots in the full span on the fixed marker database 32, the upper limit value and the lower limit value, and this is set in the variable marker database 33 (see FIG. 20 (a)). To do.

Further, the alarm information of the previously inputted process value is inputted from the process database 4 by using the input point number indicating the alarm information of the Y value, whereby the alarm state (0 =
Normal marker, 1 = alarm), and fixed marker database 3
The display color information (green = normal, red = alarm) read from 2 is converted and set in the variable marker database 33. (0 = green, 1 = red) The above process is performed for all the markers, and the data for all the markers is set in the variable marker database 33 (see FIG. 20B). Furthermore, this variable marker database 3
3 to the display control processing unit 22 (see FIG. 20A),
Make a display request.

Next, FIG. 21 shows a flow chart of processing of the marker creation processing section 31. The display control processing unit 22 reads the information of the variable marker database 33, and plots the data of the points existing in the variable marker database 33 into the display database 21 showing all the dot information on the display device 1 in order for each marker. The display database 21 is created by processing. The display database 21 created in this way is sent to the display device 1. The display device 1 displays markers according to the information in the display database 21. The display example is shown in FIG.

[0007]

However, in the conventional plant monitoring apparatus as described above, the marker display order is constant, the plant state changes, and the marker display priority order changes accordingly. Since the order cannot be changed, multiple markers overlap (display position (X,
If Y) are the same), the marker with the higher display priority order may be hidden behind the other markers to be seen, and the monitoring is not sufficiently performed.

The present invention has been made in view of the above circumstances. According to claim 1 of the present invention, when a marker having a high display priority exists, a marker having a high priority is displayed even if the display priority changes. The display aims to provide a plant monitoring device that is not always hidden by other markers.

According to claim 2 of the present invention, the marker with high priority is displayed without being hidden by other markers, but by displaying this marker blinking, the display of the marker hidden below it is confirmed. It is an object of the present invention to provide a plant monitoring device that can be used.

According to a third aspect of the present invention, the displayed markers are blink-displayed at all the marker display positions on the display device in which the display positions of the markers overlap and only one marker can be confirmed for display. Therefore, it is an object of the present invention to provide a plant monitoring device that enables confirmation of the display of markers that are hidden by the number of overlappingly displayed portions.

According to claim 4 of the present invention, by changing the display priority of the markers in order at a constant cycle, the markers hidden under the other markers at a certain display timing are also displayed at a constant cycle. It is an object of the present invention to provide a plant monitoring device capable of confirming its existence.

[0012]

In order to achieve the above-mentioned object, the first aspect of the present invention is to provide a process monitoring system for inputting process information from a plant in a plant monitoring apparatus for displaying the state of the plant by a marker. A process input section to be created, a process database having process data necessary for display, a marker priority database showing the display priority of each marker based on the process database, an input point pointing to process data necessary for display, Fixed marker database having display color information and process value-coordinate conversion table, variable marker database having marker display position and color information, the fixed marker database is read, process data is input, and the marker priority database is read. And a marker creation process for creating the variable marker database And a display control processing unit that creates information in the variable marker database in the display information that is displayed in order from the marker with the lowest priority according to a request from the marker creation processing unit, and whether to display in dot units A display control unit having a display database having display color information, and a display device in which a marker having a high priority is displayed without being hidden according to data from the display control unit.

According to a second aspect of the present invention, in the plant monitoring apparatus according to the first aspect, the marker creating section determines a marker having the highest priority and sets a blink display to the marker for a blink marker creating processing section. In addition, the marker having the highest priority is blink-displayed, and the display of the marker hidden under the blinking can be confirmed.

According to a third aspect of the present invention, in the plant monitoring apparatus according to the first aspect, the marker creating section blinks and displays a marker having a higher priority among markers whose display positions overlap. When the display positions of the n sets of markers overlap, a blink determination processing unit that determines the display position and priority of each marker so that the n markers can be further confirmed, and sets the blink display is provided. It is characterized by being

According to a fourth aspect of the present invention, in the plant monitoring apparatus according to the first aspect, the marker creating section has a marker priority creating processing section that sequentially changes the priority of each marker at a constant cycle. However, even if there is a marker hidden under another marker, the presence of the marker can be confirmed by changing the display priority at a constant cycle.

[0016]

According to the first aspect of the present invention, the process database 4 creates and updates the data necessary for display from the process input by the process input unit 5 at a constant cycle.
Binary process data and 1 for each marker
Process information including one alarm status signal is input for the number of markers. Based on the data, the marker creation processing unit 31 of the marker creation unit 3 determines the display priority of the marker (determines that the alarm state = high priority), assigns the priority number of each marker, and sets the marker priority database 34. create.

The marker creation processing section 31 creates the data required for marker display in the variable marker database 33 in the order of low priority in the marker priority database 34.
At that time, the process value is converted into a coordinate, and the variable marker database 33 is configured by combining the number indicating the marker symbol and the display color.

The display control processing unit 22 causes the display device 1 to display the markers in the order of the marker display data arranged in the variable marker database 33. When the marker display positions X and Y are the same, first, the data in the variable marker database 33 located at the upper side (not having high priority) is set in the display database 21, and thereafter, the variable marker database 33. The lower (higher priority) data is overwritten on the same point, and the marker with the higher priority is displayed on the display device 1.

When the display priority of the marker changes (a marker in the alarm state disappears and another marker becomes the alarm state), the priority changes and the marker priority database 34 is created. The variable marker database 33 is configured in that order, and the markers are displayed on the display device 1 so that the high-priority markers that are arranged in the variable marker database 33 are overwritten.

The claim 2 of the present invention is basically the same as the claim 1, but the blink marker creation processing unit 3

Here, the priority is read, and blinking is set for the marker having the highest priority. In response to this, at the display position of the marker having the highest priority, the display database 21 is sent from the display control unit to the display device so that the marker and the marker hidden below are alternately displayed. Then, on the display device, the marker with the higher priority blinks and the display of the marker below it can be confirmed.

In claim 3 of the present invention, which is basically the same as claim 1, blink determination is performed while the marker creation processing unit 31 creates the variable marker database 33 and sends it to the display control processing unit 22. Blink display determination by the processing unit 35 is added. Here, the display position of the variable marker database 33 is read, and a set of markers that also match X and Y is searched. If there is corresponding data, blink display is set for data having a high display priority (located below the variable marker database 33) to create the variable marker database 33. The display device receives the variable marker database 33 from the display control unit, and the display device performs blinking display of markers having overlapping markers to monitor more information.

The claim 4 of the present invention is basically the same as the claim 1, but the marker priority creation processing section 31 "is used.
In, the priority of each marker is unconditionally set. This priority changes sequentially in a fixed cycle, and the priority of all markers changes in each cycle. In accordance with this priority, the marker priority creation processing unit 31 ″ creates variable marker data,
Based on this, the display control processing unit 22 displays the display database 2
Create 1. Markers are displayed on the display device based on the display database 21. At the place where the marker display positions overlap, only one marker display can be checked at a time, but the markers displayed on the display device also change in order as the priority of the marker changes in order at regular intervals. Change.
