[0006]

FIG. 1 shows a display screen 1 of, for example, a CRT display device and an arrangement and a configuration example of a mode selection key 2 and an HF key 3 around the screen 1 used in the display method of the present invention. In the drawing, the CRT screen is, for example, 640.
It is a color graphic display composed of a pixel matrix of points × 480 points or 1024 points × 768 points. The display contents of the display screen 1 shown in the figure are examples of a mode list display screen when the apparatus is started up and started. The mode selection key 2 includes main mode keys 1 to 5, sub mode keys 1 to 3, and a master key in order from the top along the right side of the screen 1. The HF key 3 is located at the bottom of the screen 1. HF1 to HF10 are provided in order from the left along the side, and the display contents of the screen 1 and the selection display of the selection mode display section 4 on the right side of the screen are switched according to the selection of the main modes 1 to 5, and the main selection mode is selected. The sub mode that can be used in the mode display section 4 is displayed in a corresponding portion of the mode display section 4, and the contents of the HF key that can be used in the selection mode are displayed in a corresponding section of the HF key display section 5 at the bottom of the screen. Is done.

Since the mode list display screen shown in FIG. 1 is a display screen of the control device of the numerically controlled electric discharge machine, the case of the electric discharge machine will be described below as an example. I do. At the start of electric discharge machining, turn on the power and start up the device.Mounting of machining electrode and workpiece, setting of positioning and selection of various machining conditions are completed. Then, the display content of the display screen 1 of the display device is switched to a so-called status display screen for observing a state such as a processing state, a processing progress state, or a current position. When the display mode is selected, for example, a display mode basic screen as shown in FIG. 2 is displayed. In the screen, "current position" indicates the current position in the work coordinate system, "start position" indicates the coordinate value with the origin of the minus mechanical limit position of each axis, and
“Processing total length” is an indication of the actual moving distance from the start of processing to the current position. However, on this screen, it is difficult and inconvenient to view various types of information as a screen for viewing, checking, or displaying the current state of processing that is constantly changing, and therefore, during the sub mode switch, "Large screen"
And a "discharge graph" or the like having one or more screens. When the sub-mode switch 1 is selected, as shown in FIG. 3, the machining position on the XY coordinates and / or the machining depth in the Z-axis direction that changes every moment. Or the coordinate value of the electrode operating position and the current processing speed (for example, the processing length per unit time) are each oversized on a digital display, so that the operator can easily visually recognize the progress of the processing and the current state. , So that it is easy to determine.

A status display screen similar to the status display screen shown in FIG. 3 includes a master mode in which automatic operation is performed by an NC program input from an external device or an NC program in which graphics are drawn, and a manual mode in which operation is performed by manual input. In general, a plurality of types are provided, respectively. For example, a status display screen related to the processing of the submode switch 1 in the latter manual mode is shown in FIG. Thus, in FIG. 4, 4A is X
・ Display area of the current values of the Y and Z axes, 4B indicates the display area of the current values of the U, V and W axes, and 4C indicates contact with the machining liquid level or during the movement of the U axis origin before starting machining. Area where the main state of the machine is displayed, and a graph of the discharge state is displayed during machining, 4D is the file name display area of the currently executed NC program, 4E is the machining speed, offset amount, and the depth of the subprogram nest. And display area for remaining number of loops, 4F
Is the display area for the comment message, and 4G is the running N
This is a display area for C programs and other data and messages.

On the other hand, the editing mode of the main mode switch 2, the setting mode of the switch 4, and the like, each having a large number of displays or operations, or a work screen, can be said to be the display mode of FIG. It is of a configuration and type similar to the basic screen, and it is required to input, set, or change or update settings for the next or subsequent work even during the above-mentioned processing status display etc. It is often the work screen to be performed, but just because the state display screen that requires a certain degree of observation etc. during processing is not displayed, the work such as input and setting is performed only on the work screen display This is desirable to avoid because it may not be possible to respond promptly to the occurrence of an unexpected abnormal condition. Therefore, if possible, a state display screen as shown in FIGS. Is on the screen Class, in which configuration or the like on a display screen to each determination of a color display device in the form of from a display screen such as different work screen whatever had it is desired to simultaneously display the state that can be visually recognized.

FIGS. 5A and 5B show an example of a work screen or the like which is to be displayed on the display screen so that each can be distinguished and visually recognized in an overlapped state at the same time as the state display screen of FIG. 3 and / or FIG. Specifically, various conditions relating to the operation displayed when the setting is selected by the main mode switch 4 and "operation" is selected by the HF key 3, that is, NC

And the scanning position is V = (i = 639) (j = 47)
When the number reaches 9), one vertical scan has been completed, and the process returns to step S21 to return to the above video ram 11.
The operation of writing the composite color data of the pixels of the plurality of display screens into the memory of F is repeated, for example, by 30 frames, that is, 30 times per second, and thereafter. And during this time, the video ram 11F and C
As shown in steps S31 to S35 of the flowchart of FIG. 8, the video signal generator 11K provided between the video signal generator 11K and the RT display device 11A.
The composite color data written in the memory is sequentially read out by horizontal and vertical scanning, and output as a video drive signal to the CRT display device 11A. A screen display that can be identified and viewed by the combined color data of the pixels is performed.

In the above description, the video ram 11F
Is one screen of a CRT display screen, for example, 640 points × 48
R having an address corresponding to the pixel matrix of 0 points
The memory configuration for each address is, for example, a memory having a total capacity of 18 bits in which 6 bits are assigned to each ternary color (R, G, B). It is possible to set data of luminance of 0 to 63 levels for each color. Accordingly, step S2 in FIG.
The color data of the pixel at the same position in the scan of the screen PC and the PS in 4 is numerical data indicating which of the 64 levels of each color separated into the ternary colors is an arithmetic logic value for each color. The sum is calculated and stored as numerical data in a memory assigned to each color at the address.

Referring to FIG. 9, a detailed description will be given of what the synthesized screen looks like on the display device 11A and how it is seen or recognized by a human. Then, in the figure, the background color of the PS is “black” as a whole, and the katakana character “Aiue….
Is a work display screen for the above-mentioned setting, editing, etc. of “blue”,
On the other hand, the PC has the above-described status display screen in which the background color is “yellow” as a whole and the foreground alphabet “A, B,” is a little smaller than the work display screen PS with “red”. Between the two screens PS and PC, FIG. 6 and FIG.
According to the method of creating the composite display screen described in FIG. 8, it is clear that there is no vertical relationship between the screens.
Is smaller, the screen PS is referred to as a lower screen and the screen PC is referred to as an upper screen. Screen PS in figure
In the part where the screen PC overlaps, the katakana "Iueo ... Mime", which was displayed in "blue" on the "black" background color of the screen PS, is a mixed color (green) of "blue" and "yellow" And screen PC
Is a mixed color (yellow) of "yellow" and "black", the capital letter "AB" of the alphabet is a mixed color (red) of "red" and "black", and the capital letter "AB" of the alphabet ”And the katakana character“ Iueo …… memme ”are displayed in a mixed color (egg white) of“ blue ”,“ yellow ”, and“ red ”. Even if a part that is difficult to see may occur, the screen PC can be distinguished and visually recognized as a whole according to the displayed image or the mixed color or its distribution, and even if a person or the same person recognizes the viewpoint or image, etc.
Is a translucent screen on the upper side, the screen PS may be seen as the lower screen, and in some cases, it may appear to have a completely opposite relationship. From the place where it can be discriminated and visually recognized, the display information has been increased to two screens without reducing the screen size. or,
As is clear from the method of creating the composite display screen in FIGS. 6 and 7 to 8 described above, each of the two screens PC and PS is not a length in which the screen display that changes every moment is performed as it is. Any screen display or the like deemed necessary to be designated by selection switching or the like can be input, access operations other than changes can be performed, and work can be performed, which is convenient.

As a display method according to the present invention, the color data of each pixel of the status display screen PC and the work display screen PS read into the storage units 11D and 11E are sequentially read out, and the corresponding data of the video RAM 11F is read. When reading into the memory at the address position, each screen PC,
Instead of synthesizing the color data of the pixel at the corresponding position of the PS by arithmetic OR, at the time of reading during the horizontal scanning, the color data of each pixel of the screen PC and the screen PS is sequentially read alternately, and the video is read. There is a method of writing data at a pixel position corresponding to the RAM 11F. That is, in the horizontal scanning, every other pixel of each screen PC and PS is alternately read and written to the video ram 11F,
In the horizontal scanning of the next line, each screen PC, PS
The read order of the pixels between them is reversed between adjacent horizontal scanning lines, that is, vertically adjacent write pixels between adjacent horizontal scan lines are written with color data of pixels of screens PC and PS different from each other. The operator reads out the color data of each pixel written to the video ram 11F by the video signal generator 11K and displays the color data on a display screen such as a CRT by horizontal and vertical scanning. When the person visually recognizes the image with the brain, the color data is discriminated and recognized as a state of being synthesized on the retina. In the alternate writing of the color data of the read pixels from the two screens to the video ram 11F as described above, the color data of the pixels adjacent to each other in the horizontal scanning direction is read and written from each of the screens PC and PS as a pair. Various changes can be made.
