[Embodiments of the invention]

Hereinafter, an embodiment of the operation part enlargement display device according to the present invention will be described with reference to FIGS. 1 to 3. FIG. 1 is a block diagram of an operation part enlargement display device. In FIG. 1, 10 is a CRT (cathode #i! tube) display device i, and on the front of the display screen of this display device IQ is a transparent contact position detection channel with the same shape as the display screen. A so-called touch panel 1 is provided. When this touch panel 11 is touched with a finger or the like, a position signal of the touched part is sent out, and its configuration is such that, for example, lines for position detection are arranged in a matrix along the X-axis and the Y-axis. Each intersection of the lines has a switch function, and when the switch at the touched portion closes, X-axis and Y-axis position signals are sent out. The X-Y position detection section 12 receives a position signal from the touch panel 1 and detects the position of the touched part from this position signal.

Reference numeral 13 denotes an image display control unit, which takes in image information of the plant control flow from an image memory (not shown), etc., converts this image information into an image signal, and displays the image on the CRT.
In this case, it is determined that, for example, a manual mode key is displayed at a predetermined position on the display screen of the position information block of the image displayed on the display screen of the CRT display device 1o. It is now possible to do so. Further, when the image display control section 13 receives an enlargement command from the central processing control section 14 and converts the image information into an image signal, the image displayed on the display screen is enlarged and displayed more than the original image. It has the ability to process things like this.

Now, 15 is an enlargement key operation end, and this enlargement key operation end 15 divides the CRT display screen into eight divided screens A to H as shown in FIG.
Enlargement keys 15-1 to 15-8 corresponding to ~H are provided, and when each enlargement key 15-1 to 15-8 is operated, the enlargement keys 15-1 to 15 - The image of the partition screen corresponding to 8 is enlarged and other partition screens A-I
(K is now displayed.

That is, when the enlargement keys 15-1 to 15-8 are operated, the central processing determines the position information indicating the position of each section screen A to H corresponding to the enlargement keys 15-1 to 15-8. The data is sent to the section 14.

Reference numeral 16 denotes an image position determination section, which receives the X-Y position detection signal sent from the X-Y position detection section 12 and the position information of the enlargement keys 15-1 to 15-8, and uses these position information to determine the position of the image. It has a function of receiving and extracting the image information held in the image display control section 13 and clearing the image information of that position.

In addition to the function of converting image information into an image signal and issuing a command according to an image display sequence for display, the central processing/judgment unit 14 has the following functions in particular. That is, when position information is received from the enlargement keys 15-1 to 15-8, the image position determination unit 16 determines and extracts the image information of the designated section screen A-H, and this function causes The image display control unit 1 issues a command to transfer the extracted image information to a section screen A-)I other than the specified section screen A-H, and to enlarge the image and display it on the CRT display screen.
3, the position information of the enlarged image and the position information of the section screens A to H showing the enlarged image.
This is a function of matching the size of the operation unit of the process 70- in the enlarged image with the contact area of the touch channel 11 based on the position information of n.

Next, the operation of the apparatus configured as described above will be explained according to the enlarged display flowchart shown in FIG. For example, when image information of a control operation function of an analog controller is taken into the image display control section 13, the image display control section 13 converts the image information into an image signal and sends it to the CRT display device 10. As a result, an image of the control operation function diagram of the analog controller as shown in FIG. 2 is displayed on the CRT display screen of the υCRT display device 10. In the displayed image, 20 indicates a computer control mode, 2 indicates an automatic control mode, and 22 indicates a manual control mode.

Further, 23 is a key for changing and setting the target amount and operation amount set in the analog controller.

Therefore, when a finger or the like is brought into contact with a portion of the touch panel 11 corresponding to these keys 21 to 23, a position signal of the connected portion is sent from the touch panel 11. The X-Y position detection unit 12 takes in the position signal from the touch panel 11,
From this position signal, the position on the touch panel 11 is detected along the X and Y axes, and the XY position detection signal is sent to the image position determining section 16. The image position determination unit 16
The image of the touched part is determined based on the Y position detection signal. For example, if it is determined that it is the manual control mode key 220 part, a signal indicating that is sent to the central processing determination unit 14.

Then, the central processing judgment unit 14 issues a command to switch to the manual mode to the analog controller.

Now, if each of the keys 20 to 23 is small in size and, for example, when pressing manual control mode 22, there is a risk that the automatic control mode key 2 will also be pressed by mistake, the operator should specify section screen E and press this key. The enlargement key 15-5 for enlarging the image on the partition screen E is pressed. Then, enlarge key 1
A position signal indicating the position of the divided screen E is sent from 5-5 to the central processing judgment unit 14tlC. Therefore, the central processing judgment section 14 sends the position signal from the enlargement key l5-5 to the image position judgment section 16, and also issues a command to the image position judgment section 16 and the image display control section 13 to Have them do something like this. First, the image position determining section 16 extracts the image information of the divided screen E from the image display control section 13 according to the position signal from the enlargement key 15-5. Here, the image display control unit 13 receives the position information of the designated partition screen E from the image position determination unit 16, and displays any one of the partition screens A-D and F-H other than the partition screen E, for example, H. Clear the image. Note that the section to be cleared may be set in advance (for example, when enlarging section E, section II, and when section A is enlarged, section D), or may be set by the operator at any time.

Then, the image display control section 13 converts the image information of the divided screen E extracted by the image position control section 16 into an image signal. This conversion is performed so that the displayed image is enlarged. Then, an image based on this image signal is sent out so as to be displayed on the partition screen H. As a result, C
As shown in FIG. 2, an enlarged image of the partition screen E is displayed on the partition screen H of the RT display screen.

At this time, the position information of the enlarged image of the partition screen E is combined with the information indicating the position of each key 24, 25, 26, etc. on the screen of the partition screen H and the position information indicating the entire partition screen H. , 25°26 and the size of the contact area of the touch panel 1.

Here, touch panel 1 corresponding to manual mode key 26
When a finger or the like touches the contact area, a position signal of the touched part is sent to the XY position detection section. Thereafter, the image of the touched portion is determined in the same way as in the above-described operation, and a signal indicating the determined image (manual control mode key 26) is sent to the central processing determination section 14. As a result, the central processing judgment unit 14 issues a command to switch to manual control mode.

As described above, in the apparatus of the present invention, the enlargement keys 15-1 to 15-
8, and in response to the position signals from these enlargement keys 15-1 to 15-8, the image display enlargement fff control unit I3 and the image position determination unit 16 convert the desired partitioned screen A-H into the partitioned screen A to At the same time, the image of the enlarged control operation function, for example, the manual mode key 26, is enlarged and displayed on a separate screen A-H, which is different from screen H. Among the control and monitoring functions of the analog controller, the computer mode key 2θ,
Automatic control mode key 21. If the size of the operation part such as the manual control mode key 22 is small and there is a risk of accidentally touching an adjacent key, it is possible to touch the adjacent key by enlarging the image of the partition screen A-H. will disappear. Therefore, when the operator touches each of the keys 20 to 22, the operator does not have to press the small keys 20 to 22 separately with his or her fingertips, and can smoothly proceed with control and monitoring operations.

Even if an ITR control monitoring function is created in advance for a process flow with a small operation part such as keys and a complex configuration, the process flow can be enlarged and displayed. Even with the control and monitoring function, operations can proceed smoothly.

〔Effect of the invention〕

According to the present invention, a desired partition screen is enlarged and displayed on a partition screen different from the partition screen by operating each operation end of the enlargement operation end provided for each partition screen of the display screen,
