Abstract

PURPOSE:To allow the rapid recognition of the position of projected images by displaying the coordinates of the images to be scrolled and fixely displaying the coordinates of the image to be window-displayed regardless of scroll. CONSTITUTION:A transfer controls section 10 sends the range of the base image set in a scroll operating section 14 to an image moving section 12 and a base image coordinate updating section 13. The moving section 12 scrolls the image data for displaying of the process within an image memory 15 by receiving this data and sends the base image data to the controls section 10. The updating section 13 similarly sends the coordinates of the base image data to the controls section 10. The controls section 10 displays such data on a display device 11. The controller allotted with a tag number and the coordinates thereof are window-displayed by a tag number coordinate setting section 17 and a window interruption display section 18 when an operator touches the tag number PIC 101 on the screen. The coordinates of the PIC 101 are held fixed even if another base image is displayed by scrolling in this state.

There is a flow diagram of the piping and instrumentation diagram of the process called the strumentation diagram. When displaying this flow, the flow is displayed as a graph, and changes in process data are updated and displayed sequentially.

On the other hand, in order to monitor the operating status of various plant processes, it is necessary to check the status before and after the process, that is, the continuity of the process. In order to meet this requirement, a method is used in which image data of the entire flow of a piping and instrumentation diagram of a process is created, and this image data is scrolled and displayed on a CRT display device.

FIG. 6 is a schematic diagram of image data applied to such a method, and this image data is displayed on a CRT display device, and the size of the output image data 1 is twice the size in the vertical direction and twice in the horizontal direction. It's the size. Note that 2 is a keyboard included in the CTR display device, and this keyboard 2 is provided with a scroll key 3. This scroll key 3 has a function of moving the image data in eight directions, including the lower layer and the left and right diagonal directions. Therefore, for example, when the upper right key 3a of the scroll key 3 is operated, the image data Scroll in the direction of arrow (a),
The image displayed on the CRT display moves diagonally upward and to the right on the image data.

CRT display devices are also equipped with touch screen functionality. The image projected on the CR, T display device is the 7th
If the image is part of the flow shown in the figure, a tag is assigned to the image. That is, 4 on the image represents a process tank, and the tag rPIcOIJ is assigned to this tank 4 and displayed on the CRT display device. However, when the operator touches this tag "PICOl, j", the image of the display panel of the regulator that controls the pressure of tank 4 will be displayed on the right side of the screen as shown in Figure 8 on the CRT display screen. or a window will be displayed.

Therefore, the operator can use this window display to change the automatic/manual mode, change the control standard setting, change various parameters for control, change the manual operation output to the control end of the control valve, etc. Perform remote operations.

However, with the above-mentioned process flow display method, it is difficult to immediately determine whether the image being displayed on the CRT display is a part of the entire process flow. For example, as shown in FIG.
If the image is tagged with OIJ, this tag rPIc
If you don't check the OIJ, you may not know which part it is.

Therefore, when scrolling an image, it is difficult to know which direction to scroll in order to display the desired image, which confuses an inexperienced operator.

Also, the window display is always fixed on the right side of the screen,
It doesn't change even if the image changes due to scrolling. Then, to clear this window display, use the tag rPI again.
You will touch cOIJ. For example, even if the image on the CRT display device shown in FIG. 8 is scrolled and changed to the image shown in FIG. 9, the contents of the window display will not change at all. To erase the window display from this state, the tag rPIcOIJ must be displayed on the screen again as shown in the image shown in FIG. Then, if you restore the image, 12
However, the direction to scroll is immediately known, so C
Smooth operation cannot be performed using RT display.

(Problems to be Solved by the Invention) It is difficult to know in which direction to scroll to display a desired image, and the operation to erase the window display is complicated.
