Description

  The present invention relates to a plant monitoring display device for a thermal power plant in which four-screen display is performed.

  In a plant of a thermal power plant, a plurality of screens (for example, four screens) are usually displayed on one display device. However, the four-screen display of a conventional plant monitoring display device is a screen that an operator wants to display. Each screen was selected and displayed from the menu screen.

  For example, as four display screens, a plant monitoring device (see Patent Document 1) that displays information such as piping system diagrams and alarm displays, or a single display device that displays four screens to simultaneously monitor a plurality of plants. A plant monitoring display device that can be used has also been proposed (see Patent Document 2).

  However, in the conventional method in which the operator himself selects and displays the display screen, there is a problem that it takes time to display the screen that the operator wants to display, which takes time.

  For example, in the example of a thermal power plant, first, when the entire menu screen is displayed, buttons indicating the functions for operating the plant are displayed. The operator performs an operation of selecting one of the displayed buttons to display various screens. By this operation, for example, a menu screen related to the entire piping is displayed. Since the piping display screen covers a large number of pages (screens), a necessary page is selected and displayed. In this way, the conventional method requires a lot of time and effort for the operator to finally find a screen to be displayed.

  The object of the present invention is to solve the above-described problems, save labor for selecting screens in four-screen display, and select the optimal screen required by the operator and display it on four screens. That is.

In order to solve the above problems and achieve the object of the present invention, the present invention is a plant monitoring display device having a four-screen display, and the number of times the screen is displayed by the operator and the number of times displayed on the displayed screen. A display recording unit that records the number of operations performed by the operator, a calculation processing unit that calculates three screens with a high display frequency of the operator based on the display number and the number of operations, and 3 obtained by calculation. Display means for displaying three screens at three locations in the four-screen display, and the arithmetic processing unit further calculates a relationship degree coefficient of the screens related to the three displayed screens as the number of display times. , The display priority coefficient calculated from the operation count, the display count weighting coefficient input by the operator, the display priority coefficient calculated from the operation count weighting coefficient, and the related screen weighting coefficient input by the operator. The most relevant to the screen With selecting the screen as a related screen, the optimum screen call feature with plant monitoring display device and displaying the selected the associated screen as the fourth screen in the QUAD.

Moreover, as a preferable form of the present invention, the screens related to the three screens include a plurality of screens having different weighting coefficients for each of the three screens having a high display frequency. The relevance coefficient is obtained by the sum of relevance coefficients of a plurality of screens having different weighting coefficients and related to the three screens .

  According to the present invention, the four screens displayed on one display device are automatically selected for each operator based on the number of display times and the number of operations displayed in the past. There is an effect that the labor and time as described above are not required before displaying.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing an embodiment of a plant monitoring display device according to the present invention.

As shown in FIG. 1, the plant monitoring display device in this example includes a display means 1 for displaying the state of the plant in four screens, an operation input means 2 for inputting an operator and related information, and these external devices (externally attached). Device) and an input / output control unit 3 serving as an interface between the processing unit and the arithmetic processing unit.
The plant monitoring display device further includes a display recording unit 4, an arithmetic processing unit 5, a display operation weight coefficient table 6, a related screen weight coefficient table 7, and a related screen table 8 which will be described later.

Next, the operation of the plant monitoring and display apparatus configured as described above will be described.
First, when the plant monitoring display device is started up, “Please enter the operator name” is displayed on the screen of the display means 1, so the operator inputs the operator name using the operation input means 2. . The input operator name is recorded in the display recording unit 4 via the input / output control unit 3.

  Next, the operator uses the operation input unit 2 to display an arbitrary screen on the display unit 1. Here, an arbitrary screen includes a screen showing plant piping and a screen of temperature and flow rate trends for a specific part of the piping, but here it means an appropriate screen required by the operator. is there.

  The display count of the screen displayed by the operator is recorded in the display recording unit 4 via the input / output control unit 3. Since the number of times this screen is displayed is information related to the operator, when this is recorded, it is recorded as related information of the operator name recorded in advance.

  Next, the operator uses the display unit 1 and the operation input unit 2 to perform an arbitrary operation on the display screen. Here, the arbitrary operation means that a symbol or an analog value appearing on the display screen showing the piping is clicked. For example, when a pump in a pipe is clicked, a window displaying the state of a digital input signal from the plant is displayed, which shows whether the pump is in an activated state (ON) or a stopped state (OFF). When an analog value is clicked, a trend of the analog value is displayed in a window.

  Here, the number of operations on the screen means the number of times the operator clicked on a specific pump on the display screen, and this number of operations is recorded in the display recording unit 4 via the input / output control unit 3. Is done. In this recording as well, the information related to the operator name stored in advance is recorded together with the number of display times described above.

FIG. 2 is an example of a recording result of the display recording unit 4.
The operator W is a person who operates a plant, for example. As shown in FIG. 2, it is recorded that the operator W displays the screen A E times and performs the operation I times on the screen A. Similarly, screens B, C, D,... Are displayed F times, G times, H times, etc., and J times, K times, L times, etc. on the respective display screens. Records that the operation was performed.

The operator WW can be assumed to be, for example, a person who manages the entire plant operation, that is, a person who manages the operating operator W. The screen displayed on the display means 1 does not necessarily match between the driving person and the managing person.
Screens AA, BB, CC, DD... In FIG. 2 are screens displayed by the operator WW, and each screen is displayed EE times, FF times, GG times, HH times, and so on. This shows that operations of II times, JJ times, KK times, LL times,... Have been performed on the display screen.

  The number of displays and the number of operations shown in FIG. 2 are used when selecting three screens displayed in association with the operator W or the operator WW, and the fourth number associated with each operator described later. It is also used when calculating the screen (related screen).

  Next, the operator inputs a display count weighting coefficient for each screen displayed on the display unit 1 through the operation input unit 2 and performs any operation (for example, click of a pump, etc.) on the display drawing. ) Is input (weighting coefficient for the number of operations).

Here, the display count weighting factor is an operator that “weights” the importance of each displayed screen, and is usually set to a range between “0” and “1”. Is done.
Similarly to the display count weighting coefficient, the operation count weighting coefficient also “weights” the importance of the operation on the display screen (for example, click of the pump), and similarly “0” and “1”. Set to a range between.

  Depending on the screen, there are screens in which the operator only needs to see what is displayed and does not need to be operated at all. In such a display screen, the display count weighting factor is close to “1” and the operation count weighting factor is “0”. It is a value close to "." In addition, on the screen where it is necessary to frequently monitor the start and stop states of the pump or to constantly monitor the temperature of a specific part of the piping, even if the display count weight coefficient is low, the operation count weight coefficient is It is set to be close to “1”.

  The input display frequency weight coefficient and operation frequency weight coefficient are recorded in the display operation weight coefficient table 6 via the input / output control unit 3. These weighting factors are also used when selecting three screens displayed in relation to the operator, and also when calculating a fourth screen (related screen) related to the three displayed screens. Used.

FIG. 3 shows an example of the input result of the display operation weight coefficient table 6.
As an example, the screens A, B, C, D,... Related to the operator W will be described. Similarly, for the screens B, C, D..., The display frequency weighting coefficients are N, O, P... And the operation frequency weighting coefficients are R, S, T. .

  Next, the operator uses the operation input unit 2 to input a related screen weight coefficient. For example, the operator W is described as an example of the related screen. If the screen A is a piping screen, the related screen may be a trend graph of temperature at a specific location or a trend graph of flow rate or pressure. In FIG. 4, different weighting factors are input for the related screen (1) and the related screen (2). That is, the weighting coefficient of the related screen (1) is U, and the weighting coefficient of the related screen (2) is V. These weight coefficients are recorded in the related screen weight coefficient table 7 via the input / output control unit 3. Here, U> V.

  Next, the operator W uses the operation input means 2 to display other screens having high relevance for each of the screens A, B, C, D,. 1) Input as related screen (2). For example, for the screen A, the screen X is selected as the related screen (1), and the screen Y is selected as the related screen (2). Similarly, for the screens B, C, and D, the screens Y, Z, and X are selected as the related screen (1), and the screens Z, X, and Y are selected as the related screen (2). These related screens (1) and (2) are recorded in the related screen table 8 via the input / output control unit 3. FIG. 5 is an example of the input result of the related screen table 8.

  Next, based on the flowchart shown in FIG. 6 and the block configuration diagram of FIG. 2 and the calculation charts of FIGS. 7 and 8, in this example, a method for selecting three screens to be preferentially displayed according to each operator, A method for selecting related screens related to these three displayed screens will be described.

  First, an optimal screen call button (not shown) is pressed (clicked) by the operator name W input on the display screen (step S1). The pressing of the optimum screen call button is a start operation for selecting four screens that the operator W desires to display.

When this optimal screen call request is executed, the operator name recorded in the display recording unit 4 shown in FIG. 2 is selected and transmitted to the arithmetic processing unit 5 via the input / output control unit 3. .
Then, information indicating that the optimum screen calling button has been clicked, that is, a request for the optimum screen calling function is transmitted to the arithmetic processing unit 5 via the input / output control unit 3.

  The arithmetic processing unit 5 that has received this optimum screen call request is shown in FIGS. 2 to 4 stored in the display recording unit 4, the display operation weight coefficient table 6, the related screen weight coefficient table 7, and the related screen table 8. The optimal screen calling process is started using the data to be stored.

  That is, as shown in FIG. 6, when the call button for the optimum screen is pressed, the display priorities of the plurality of screens A, B, C, D... Related to the operator W are calculated (step S2). . Specifically, the display priority AA of the screen A is calculated by the arithmetic expression shown in FIG. 7 (step S21).

  In this calculation, the calculation processing unit 5 displays the display screen weighting coefficients M, N, O, P,... For each of the screens A, B, C, D. Read the operation frequency weighting factors Q, R, S, T.

Next, based on these read data, the arithmetic processing unit 5 calculates a display priority indicated by a frame 9 in FIG. First, the display priority coefficient AA is calculated for the displayed screen A.
The display priority coefficient AA is a value obtained by adding a value obtained by multiplying the display count E of the displayed screen A by the display count weight coefficient M and a value obtained by multiplying the operation count I by the operation count weight coefficient Q.

  The display priorities BB, CC, DD,... For screen B, screen C, screen D,... Are calculated in the same manner as shown in FIG.

  Next, the display priority coefficients of the displayed screens are compared, and the ranking is given in descending order of the display priority coefficient. This order is the priority for displaying, that is, the display priority. As shown in FIG. 7, the display priorities of the screens A, B, C, D... Are AA> BB> CC> DD. In the descending order, that is, screen A, screen B, and screen C are selected.

  As described above, when the three screens to be displayed are determined, the arithmetic processing unit 5 transmits a request to display the three screens with high display priority on the display unit 1 to the input / output control unit 3. In the case of FIG. 7, a request to display the screen A, the screen B, and the screen C, which are three screens with high display priority, on the display unit 1 is transmitted to the input / output control unit 3. In response to this, the input / output control unit 3 performs control to display the three screens A, B, and C with high display priority transmitted from the arithmetic processing unit 5 on the display unit 1 (step S3).

  Next, the arithmetic processing unit 5 calculates the degree of association with the two related screens (1) and (2) related to each of the displayed three screens (step S4). First, the arithmetic processing unit 5 reads the related screens (1) and (2) of three screens having a high display priority from the related screen table 8. As shown in FIG. 5, the three screens with high display priority are the screen A, the screen B, and the screen C. Therefore, the related screen (1) is the screen X, the screen Y, and the screen Z. Further, the related screens (2) of the screen A, the screen B, and the screen C are the screen Y, the screen Z, and the screen X, respectively.

  In the relevance calculation in step S4, the arithmetic processing unit 5 first calculates the relevance coefficient of the relevance screen (1) (step S41). That is, for each of the three screens A, B, and C with high display priority, the relevance factors AA1, BB1, and CC1 of the related screen (1) X, Y, and Z are calculated. The relevance factors AA1, BB1, and CC1 of the related screen (1) are, as shown in the frame 10 of FIG. 8, the display priority of the screen with the high display priority related to the related screen (1) X, Y, and Z. It is a value obtained by multiplying the coefficients AA, BB and CC by the related screen weight coefficient U.

Similarly, as shown by the frame 11 in FIG. 8, the relevance factors AA2, BB2, and CC2 of the related screens (2) Y, Z, and X of the screens A, B, and C are calculated (step S42).
That is, since the related screen weight coefficient of the related screen (2) is V, the display priority levels AA, BB, and CC of the screens A, B, and C are multiplied by the weight coefficient V of the related screen (2), and the related screen ( The relevance factors AA2, BB2, CC2 of 2) are obtained.

  Next, in the flowchart of FIG. 6, relevance factors XX, YY, and ZZ are calculated for each of the related screens X, Y, and Z related to the three screens that are displayed obtained in step S4 ( Step S5). That is, the relevance coefficients XX, YY, and ZZ of the related screens X, Y, and Z are the relevance coefficients AA1, BB1, and CC1 of the related screen (1) and the relevance coefficients AA2, BB2, and CC2 of the related screen (2). Is obtained as a value obtained by adding After that, the relevance coefficients XX, YY, and ZZ of the respective screens X, Y, and Z are compared, and the ranking is given in descending order of the relevance coefficient values. This rank is the degree of relevance. In FIG. 8, since XX> YY> ZZ as indicated by a frame 12, the related screen X is displayed on the display unit 1 as the fourth screen.

  That is, the arithmetic processing unit 5 transmits a request for displaying the screen X on the display unit 1 as one screen having a high degree of relevance to the input / output control unit 3. In response to the request from the arithmetic processing unit 5, the input / output control unit 3 displays one screen X having a high degree of relevance on the display unit 1 (step S6).

  In the above description, there are two related screens, the related screen (1) and the related screen (2). However, three or more related screens may be used.

  FIG. 9 shows an embodiment of the change of the screen displayed on the display means 1 when the optimum screen calling function is requested according to the present invention. By requesting the optimal screen calling function and selecting the operator name, the display means 1 displays three screens that are frequently displayed by the operator and one screen most relevant to the three screens. Is done.
