Abstract

PURPOSE:To quicken display response by neither gathering nor processing information regarding data displayed in an area which is not displayed on a screen and overlaps with the screen at the time of a multiwindow display. CONSTITUTION:A screen management part 16 recognizes a case wherein a window is newly opened, finds the number of windows which are currently opened on the screen, and finds an overlap of images when the number of the windows is >=2. When >=2 windows overlap with each other, how much the 1st image and 2nd image overlap with each other is found and when four images overlap with one another, the overlap of a 2nd image, the overlap of a 3rd image, and the overlap of a 4th image with a 1st image are calculated. When this overlap quantity is less than a set value, the gathering of information to be displayed in the overlap area and computation for the display are stopped, but when the overlap quantity is larger than the set value, the gathering of information of the whole window positioned at a hidden part and the computation for the display are stopped.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a screen display control device used for a monitor device used in a production factory, for example.

[0002]

2. Description of the Related Art At a production site, various monitor devices are provided so that the operating conditions of various production machines can be seen at a glance and the assembly condition of a vehicle can be centrally controlled.

Recently, many of these monitor devices are provided with a multi-window for simultaneously displaying a plurality of windows on one screen and viewing a plurality of information at once. The multi-window control is performed by the screen display control device.

[0004]

However, in such a conventional screen display control device, when displaying in a multi-window, as shown in FIGS. 4 (A) and 4 (B), point names are displayed. Alternatively, all data specified in advance as group point names are collected, and calculations are performed on the collected data to generate a multi-window screen. The display may take a long time, and the display response was not very satisfactory.

This is due to the fact that even the information about the screen which is almost hidden when displaying in a multi-window is collected and the calculation is performed.

The present invention has been made in order to reduce such a conventional problem, and when displaying in a multi-window, the information hidden in other screens is not collected and operated. An object of the present invention is to provide a screen display control device that improves display response.

[0007]

The present invention for achieving the above object provides a screen display control device having a function of displaying necessary information on display means in a multi-window.
When the input means for inputting the information to be displayed on the display means and the plurality of images to be displayed on the display means at the same time are related to the input means, at a position hidden by other images. It is characterized by having an information extracting means for extracting only information other than the information to be displayed and a screen generating means for generating a screen to be displayed on the display means based on the information extracted by the information extracting means.

[0008]

The present invention thus constructed operates as follows.

The input means inputs information to be displayed on the display means. When the information input by the input means is related to a plurality of images to be displayed on the display means at the same time, the information extraction means extracts only information other than the information displayed at a position hidden by other images. That is,
Select and enter only the information corresponding to the part displayed as a screen. The screen generation means generates a screen to be displayed on the display means based on the information extracted by the information extraction means.

Therefore, it is not necessary to collect and calculate the information of the portion corresponding to the image hidden by the multi-window, and the display response of the screen is improved accordingly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of a screen display control device according to the present invention, and shows only a part relating to the gist of the present invention.

In the figure, a screen information file 10 stores information for generating an image to be displayed on a display device such as a CRT. Also, point file 12
Stores a point registration table and a group point registration table similar to those shown in FIG.

The information stored in the point file 12 is managed by the point management unit 14. The screen management unit 16 that functions as a screen generation unit mainly generates an image to be displayed on the CRT that is the display unit based on the information stored in the screen information file 10. The input determination unit 18 is a unit that determines which information should be extracted from the input information based on a screen creation command from an external device and extracts only the necessary information. It functions as a means and an information extraction means.
The point state determination unit 20 is a unit that determines what the point state of the information stored in the point file 12 is. The monitoring point recognition unit 22 is a unit having a function of recognizing which monitoring point is based on the information from the screen management unit 16 and the input determination unit 18.

The screen display control device configured as described above operates as follows based on the flowchart shown in FIG.

First, the screen management unit 16 recognizes that a new window has been opened or that the position of the window has been changed using a mouse or the like (S1), and the window currently displayed on the screen is recognized. (S2). When the number of windows is two or more (S3), the overlap of the respective images is obtained. For example, when the number of images is two, it is calculated how much the first image and the second image overlap, and when the number of images is four, the first image is The overlap of each of the second, third, and fourth images is calculated. That is, FIG.
As shown in, the degree of overlap between the screens will be considered (S4).

If the overlapping amount is smaller than the set value (S5), the calculation for collecting and displaying the information displayed in the overlapping area is stopped (S6). on the other hand,
If the overlapping amount is equal to or more than the set value, the information collection of the entire window located in the hidden portion and the calculation for the display are stopped.

For example, as shown in FIG. 3 (A), when there is not much overlap of screens (hatched part), the information necessary for the calculation of the data displayed in the part which overlaps below and becomes invisible is collected. Since the calculation is not useful, the information necessary for that part is not collected and calculated. Further, as shown in FIG. 7B, when most of the image is overlaid on the upper screen and disappears, information collection and calculation for displaying the entire image below is performed. Absent.

The information collection in steps S6 and S7 is stopped by the input judging section 18, but the information selectively extracted here is managed by the point managing section 14 and the screen managing section. Is used as information for screen generation (S7).

Next, if there are other overlapping screens, for example, if there are four screens, the first screen, the third screen, the first screen and the fourth screen. In the same manner as described above, the process of sequentially obtaining the overlapping state of each screen up to the n-th screen is performed (S8, S9).

As described above, according to the present invention, when displayed as a multi-window, the data displayed in the overlapping area with the upper screen is displayed on the screen which is overlaid on the upper screen and disappears. Since the information and the calculation for displaying the data are not performed, even if a large number of screens, such as 4 screens and 5 screens, are displayed in a multi-window, there is almost no relation to the display number. It is possible to display the screen in an almost constant time.

[0021]

As described above, according to the present invention, when a screen is displayed in a multi-window, the information about the data displayed in the overlapping area with the upper screen which is not displayed on the screen is collected and calculated. Since it is not provided, the time required for screen display can be shortened and the response of screen display is improved.
