JPH10207439A - Graphic screen generating device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a device which can incorporate a background in video information such as a photograph by generating such constitution that a background has a screen made by multi-media technology such as video information in addition to pixel information. SOLUTION: A generator of graphic screen generates a background using a general purpose graphic tool 10. The graphic screen generated by the general purpose graphic tool 10 is preserved by a general purpose type graphic file 20. And the preserved general purpose type graphic file 20 is stored in an integrated instrumentation system 30 through a network and the like. A graphic screen function section 32 refers to the general purpose graphic file 20 already stored, and displays the contents on a CRT display as general purpose graphic. In this case, as the general purpose graphic tool 10 is used, highly accurate background can be made.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a graphic screen generating apparatus suitable for use in industrial control equipment for displaying an operating state of a plant, and more particularly to an improvement in smoothly generating a background image.

[0002]

2. Description of the Related Art The present applicant has disclosed, for example, Japanese Patent Application Laid-Open No. 6-6826.
No. 5 discloses a graphic screen creation device. In such an apparatus, the graphic screen is displayed by being divided into a foreground image and a background image. The foreground image changes a display color and a display position in accordance with an actually measured value of a dynamically changing plant. Once a background image is created, its display color and display position do not change. Therefore, conventionally, a background image and a foreground image are created by arranging an arbitrary number of pixels (primitives) at arbitrary coordinate positions on the graphic screen using a dedicated graphic screen creation device called a graphic builder. . In addition, pixels such as circles and rectangles are required for displaying a background image.

[0003]

However, with the recent trend toward lower prices and higher performance of so-called personal computers and workstations, these general-purpose devices are used as graphic screen creation devices, It is desired to incorporate it into a background image in video information such as a photograph that has not been used. However, the conventional graphic builder is not good at handling video information such as photographs, and has a problem that it cannot sufficiently meet customer needs. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has as its object to provide a graphic screen creation device that can be incorporated into a background image in video information such as a photograph.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a foreground image in which a display color and a display position are changed in accordance with an actual measurement value of a dynamically fluctuating plant. In a device for creating a graphic screen for displaying the operating state of the plant using a color and a background image whose display position does not change, the background image is created by multimedia technology such as video information in addition to pixel information. It is characterized by having a screen to be displayed.

According to the configuration of the present invention, a screen created by multimedia technology such as video information can be incorporated in a background image, so that a graphic screen that allows a customer to easily recognize the operation state of a plant can be easily created. it can.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a configuration block diagram showing one embodiment of the present invention. In the figure, a general-purpose graphic tool 10 creates a background image. For example, drawing software or CAD software used in a personal computer is used. The general-purpose graphic file 20 is a file storing background image information, and has a format such as a Windows bitmap. The integrated instrumentation system 30 includes a man-machine interface device used for operation and monitoring of a plant, a control device on the site side, and the like. The graphic screen function unit 32 has a function of displaying a graphic screen in the man-machine interface device. The CRT display unit 34 is a CRT in a man-machine interface device, and may be another display device such as a liquid crystal display or a plasma display.

[0007] The operation of the apparatus thus constructed will be described below. The arrows in FIG. 1 respectively indicate file storage, file reference, and background image display. The creator of the graphic screen is a general-purpose graphic tool 10
Create a background image using. The graphic screen created by the general-purpose graphic tool 10 is stored in a general-purpose graphic file 20. Then, the saved general-purpose graphic file 20 is stored in the integrated instrumentation system 30 via a network or the like. The graphic screen function unit 32 refers to the already stored general-purpose graphic file 20 and performs CRT display using the contents as a background image.

Here, since the general-purpose graphic tool 10 is used, a highly accurate background image can be created. Further, since the general-purpose graphic file 20 is employed, a restrained image such as a photograph can be used as a background image, and further, a background image can be created by using a multimedia technique such as sound or moving image.

[0009]

As described above, according to the present invention, since the general-purpose graphic tool 10 uses a general-purpose device such as a personal computer, a high-quality background image can be easily created. There is an effect that can be. Furthermore, since the general-purpose graphic file 20 is adopted,
The background image can be created using the multimedia technology using image information such as a photograph, and there is also an effect that a more user-friendly man-machine interface device can be provided.
