Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, when monitoring and controlling a plant using a computer system, presents the operating state of the plant to a plant operator as a monitoring screen, and displays equipment and equipment included in the plant. The present invention relates to a screen display method for displaying a plant monitoring control screen for performing the above operation from the screen and a screen display device thereof, and particularly relates to enlargement / reduction of the display screen.

[0002]

2. Description of the Related Art Conventionally, in order to display a plant monitoring control screen, a method for enlarging / reducing a single screen without changing the configuration of each display element or the ratio of display size, and a method for displaying a whole screen are described. Is divided into a plurality of parts, a screen for displaying each part individually, a screen for displaying some of the individual screens, and an individual screen display method for displaying a screen summarizing some of the individual screens. Yes, both have been used or used together according to the characteristics of the monitoring target and the content of the operation.

FIGS. 15 and 16 are diagrams for explaining a method for enlarging or reducing the entire screen. FIG. 15 is a diagram showing a situation where a part of a plant is displayed without reducing the screen, and FIG. It is a figure showing the situation where it reduced and displayed the whole plant.

FIG. 17 is a diagram for explaining a method of dividing the entire screen into a plurality of screens. FIG. 17 (a) shows a summary screen of the entire monitoring target, and FIG. 17 (b) shows a monitoring target screen of FIG. 17 (a). Is a screen displaying the upper left quarter.

In recent years, in addition to the above two methods, (1) a method of controlling the degree of abstraction of display contents according to the display magnification as disclosed in Japanese Patent Application Laid-Open No. 56-106278, 1
Japanese Patent Laid-Open No. 94496, a method in which the presence or absence of display of a display element according to the display magnification can be set interactively.
Japanese Patent Application Laid-Open No. 290379/1990, a method of adjusting display contents using priorities given to each display element in advance, (4) Draw the entire monitoring target on a virtual screen as in Japanese Patent Application Laid-Open No. 8-305527, and There has been proposed a method of providing a reduced window as an entire screen and a partially cut window as a block window.

[0006]

The following problems have been encountered as the number of monitoring control objects has increased and the number of display elements constituting the screen has increased.

In the method of enlarging or reducing the entire screen, when the screen is reduced to display a wide range of monitoring and control targets,
The size of each display element displayed on the screen becomes small, and it becomes difficult to identify each display element. Further, even if the user can identify to a certain extent, there is a problem that the selection target is too small and the operation becomes inconvenient when selecting the operation to perform the operation on the display target.

Although the above-mentioned problem does not occur in the method of dividing the screen into a plurality of screens, the summary screen needs to be created separately from each of the partial screens.

In the method disclosed in Japanese Patent Application Laid-Open No. 56-106278, in which the degree of abstraction of display contents is controlled in accordance with the display magnification, it is necessary to prepare display elements in advance for each magnification. Similarly, there is a problem that the man-hour for screen creation increases.

Japanese Patent Laid-Open No. 2-194496 discloses a method for interactively setting the presence or absence of display of a display element in accordance with the display magnification, while solving the problem of man-hours and partially solving the problem of visibility. There is a problem that the operator needs to set which display element to keep one by one, and when the display element is reduced while displaying adjacent display elements together, a situation where they overlap may occur, but a means to adjust it is provided. There is a problem that cannot be done.

The method of adjusting the display contents using priorities given to the respective display elements in JP-A-6-290379 both improves the visibility and man-hours, and the display contents are automatically determined. And the problem of overlapping adjacent display elements is solved, but it only provides control of screen switching, cannot cope with arbitrary enlargement / reduction, and has omitted display elements such as bypass valves. When there is dynamic information such as the open / close state, there is a problem that a means for displaying the state is not provided.

The method of cutting out a block window from a virtual screen disclosed in Japanese Patent Application Laid-Open No. 8-305527 can provide partial screens without individually creating partial screens. However, a reduced overall system diagram cannot be used for system monitoring. It is limited to the application that calls the block window, and there is no function to provide an overall diagram showing the operating status of the entire monitoring target.In addition, the contents of individual system block diagrams are cut out from the overall system diagram by the screen size There is a problem in that there is no function of providing a partial view for displaying an arbitrary part at once because it is limited to the partial view.

The problem to be solved by the present invention is to solve both the problems of the visibility and the man-hour described above, and to cope with arbitrary enlargement / reduction without specifying display information by an operator, and to omit dynamic information. It is another object of the present invention to provide a screen display method and a screen display device for automatically generating a partial screen of only a specific portion while presenting the summary information as summary information.
