Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a screen display device that displays the status of an electric power system, calculation results, etc.

(Prior Art) Generally, Visual Display Unit
When referring to the power system status and analysis results on the screen displayed on the VDU (hereinafter referred to as VDU), in systems with a large system scale, the number of types of screen items increases and the amount of data is large. It will not be possible to display it all above.

In such cases, divide this data into several parts,
Displaying on multiple screens.

Conventionally, even when there are a large number of screens to display, the total number of pages is not displayed on the screen, so it is difficult to recognize the total number of pages until the last page is displayed.

Furthermore, if the screen that the operator should refer to is near the last page in order, the operation to display the next page must be repeated until the screen in question is displayed, which is troublesome and time consuming. required.

(Problem to be Solved by the Invention) According to the conventional screen display method, since the total number of pages on the screen to be displayed is unknown, the serial page number of the screen to be displayed (the number of the target page in the whole) is unknown. It is impossible to predict the page number (which indicates which page corresponds to the page),
Furthermore, if the currently displayed screen is a screen with a serial page number close to the final page, it is necessary to repeat operations similar to selecting the next page until the screen is displayed. Therefore, the conventional method has the problem of not only increasing the burden on the operator but also reducing operational efficiency.

When displaying the power system status and analysis results on the screen, the present invention allows the operator to know the total number of pages, and
It is an object of the present invention to provide a screen display device that makes it possible to quickly display a screen displaying the system status or analysis results that you want to refer to by setting a serial page number for the screen.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a screen display device that displays on the screen of a VDU using the following means.

When an operator makes a request to display a desired screen using an input device, a sequential page number setting means is provided to determine which page the request is for, calculate the total page number of the requested screen, and display data for the page desired to be displayed. It is composed of a display data importing means for importing and storing, and a screen data display means for displaying on the VDLI screen a screen of the total page number of serial page number 1 stored by the above two means and the serial page number to be displayed.

(Function) First, when the operator requests display from the input device,
The serial page number setting means reads the requested serial page number and stores it in the display information file.

Next, the display data importing means retrieves the display data of the serial page number requested for display from the display data file, and calculates the total number of pages that the screen has,
It is also stored in the display information file.

Finally, the screen data display means extracts the serial page number, total page number, and display data corresponding to the serial page number requested by the operator to be displayed from the display information file and displays them on the display device.

(Example) The present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a screen display device according to the present invention.

In FIG. 1, 1 is a display data file in which display data is stored, 2 is a display data importing means, 3 is a display information file, 4 is a serial number setting means, 5 is an input device, 6
7 is a screen data display means, and 7 is a display device.

Next, the action will be explained.

The operator inputs the serial page number of the screen to be displayed using the input device 5. The serial page number setting means 4 takes in the serial page number set by the input device 5 and stores it in the display information file 3.

The processing contents of the serial page number setting means 4 will be explained using the flowchart shown in FIG.

The following methods are available for the operator to request screen display.

Firstly, when requesting display for the first time from a state where nothing is displayed (referred to as an initial display request), secondly, from a state where a certain screen is displayed, a request is made to display the screen with the consecutive page number of one page before or after. (referred to as previous page/next page selection), or when requesting to display a screen by inputting the serial page number of the requested screen while the third screen is displayed (referred to as serial page selection) There are three types.

When the operator issues a screen display request using the input device 5, the serial page number setting means 4 is activated, and it is determined in step 52-1 whether or not it is an initial display request.

In the case of an initial display request, the process advances to step 52-3.

In step 52-3, the serial page number 1 is stored in the display information file 3. If there is no initial display request and the screen is already displayed, the process advances to step 52-2 and it is determined whether the next page is to be selected. In the case of selecting the next page, the process advances to step 52-4, and the serial page number next to the serial page number of the currently displayed screen is stored in the display information file 3. Furthermore, if the next page is not selected, step 5
Proceed to 2-5, and store the input and set serial page number in the display information file 3.

From the above, the serial page number of the screen that the operator wants to display is
It is stored in the display information file 3.

Next, the processing contents of the display data importing means will be explained using the flowchart shown in FIG.

Step 53-1 reads the maximum display number of display data per screen and all display data of the screen from the display information file 3 based on the serial page number stored by the above-mentioned means.

Step 53-2 calculates the total number of pages based on the data read in step 53-1.

Step 53-3 stores the total number of pages calculated in step 53-2, the serial page number, and the display data corresponding to the screen of the serial page number into the display information file 3.

Finally, the processing contents of the screen data display means 6 will be explained using the flowchart shown in FIG.

Step 84-1 reads the total page number, serial page number, and serial page number display data stored in step 53-2, and displays them on the display device 7 in step 54-2.

In the above embodiment, it was explained as a supervisory control system, but
The invention is not limited to this, but it is very effective if the system has screens with a very large total number of pages.

[Effects of the Invention] As explained above, according to the present invention, the amount of information such as the status of the power system and analysis results is so large that it is impossible to display all the information on the vOu at once. In addition, the total number of pages of information on the screen is displayed, along with the serial page number indicating which page of the screen the currently displayed screen is on, along with the screen's original display data. With this configuration, it is possible to provide a screen display device that can accurately display information to an operator.
