JPS5972513A - Nc color display device - Google Patents

Abstract

PURPOSE:To facilitate an easy operation when an NC indication program is read out of a memory and an NC command is fed by a key input means for editing, by displaying the specific address, word and character train in a color different from others. CONSTITUTION:An NC indication program is read out of a memory 1 and displayed on a display screen 6 of a display means 5. When a correction is required with the program, an NC command is fed by a key input means 2. A designated command detecting means 3 detects the word, address and character train with which the NC indication program is coincident with the NC command. Then the NC indication program on the screen 6 is controlled so that only the detected coincident area has a color different from other areas by a coloring control means 4. In such a way, only the designated area is displayed in a different color from other areas. Thus the edited area can be confirmed at a glance to facilitate an easy operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to an NC display device that displays an NC command program in color.Prior art and problems A display device that can display an NC command program on a CRT screen is a has been known for a long time, and with the advent of such devices, editing of NC command programs has become much easier than in the past (1). blocks are displayed together, so surprisingly it is not possible to immediately find the desired edit location.

Purpose of the Invention The present invention has been made in view of the above-mentioned circumstances: .

Structure of the Invention In order to achieve the above-mentioned object, the present invention provides C.2.
This command displays words or character strings (hereinafter referred to as NC commands) in a different color from others.

FIG. 1 is an explanatory diagram of the configuration of the present invention, which matches the NC command l' input from the key manual means 2 from the NC command program read out from the memory 1 for display.
is detected by the NC command controller specified command detection means 6,
A color change instruction for changing the coloring of only the detected part is sent to the coloring control means 4, and the display screen B of the display means 5 displays the following:
An NC command program is displayed in which only the NC command program portion detected by the specified command detection means 6 is colored differently from the rest.

Embodiment of the Invention FIG. 2 is a block diagram of essential parts showing an example of the 71-ware configuration of the color display device of the present invention, in which 10 is a microcomputer, 11 is a microcomputer 10 that executes predetermined operations (2) 12 is a RAM used for pointers and calculations, 13 is an address decoder for accessing memory, etc., 14 is a CMOS memory for storing NC command programs, 15 16 is a CRT controller that generates horizontal and vertical synchronization signals and scan addresses, 17 is a pulse oscillation circuit, and 18 is an address that switches between the CPU address and scan address. switching circuit, 19
20 is an address decoder, 20 is a character RAM that stores display characters corresponding to the display screen position (2), 21 is a color RAM that stores the color to be attached to each character on the display screen, 22
2 is a character ROM that converts the output of character RAM 2 Cl into character data, and 23 is a character ROM 2.
2. A display control circuit outputs a video signal based on the output of the color RAM 21, 24 is a CRT display section, and 25 is its screen. In addition, the character RAM
Color RA is a configuration in which color specification information is stored in 20.
M21 may be omitted.

Furthermore, FIGS. 5A and 5B are flowcharts showing an example of the software configuration of the color display device of the present invention.

For example, when an operator runs an NC machine tool from a certain NC command program (secondary), the feed rate is not appropriate, and some blocks are initially 70 inches and some blocks are 8 inches.
0%, and another block has to be set to 90% of the original feedrate.When modifying this NC command program, only the feedrate command (F code) should be displayed in yellow, and the other blocks should be displayed in green. By displaying it, you can see at a glance where the feed rate command is programmed. Taking two such cases as an example, the operation of the second illustrated device will be described below.

As shown in FIG.
When an editing operation is performed in D115, insertion as is known,
Editing processing such as deletion is performed (steps 81 and 82).
), when the color-based display command key is pressed and a specified command is input from the MD 115, a flag in the RAM 12 is set to remember that the color-based display command has been issued, and at the same time (1 An input designation command that instructs what to display in different colors is stored in the RAM 12 (step 83.
84). Incidentally, when the display key for the next page or the previous page is pressed, the display moves to the corresponding display page (step S5).

The microcomputer 10 sets a pointer in the RAM 12 indicating where in the NC command program to display (step 86), and displays the CM according to the pointer instructions.
NC command programs are sequentially retrieved from the OS memory 14 (step S7). The microcomputer 10 identifies the flag (step S8), and when a color-specific display command has not been issued, extracts standard color data from the ROM 11 and writes it to a predetermined location in the color RAM 21 (step S89), and writes it into the CMOS memory. The data retrieved from 14 is written to the corresponding address of the character RAM 20 (step 510), but if a color-based display command has been issued, it is determined whether the retrieved data matches the input command command or not. 511), if they do not match, the characters are displayed in the standard color as before, and if they match, ROM11! - Read the stored changed color data and write it to a predetermined location in the color RAM 21 (step 512), and read the retrieved data to the character RAM 21 (step 512).
20 (step 510). The above operations are performed until one screen's worth of data is completed (
Step 513).

Now, when the above processing is completed, the address switching circuit 18 is switched to the scanning address side of the CRT controller 16, and the character RAM 20 and color RAM are switched to the scanning address side of the CRT controller 16.
The contents of M21 are read out in synchronization with the scan address. Therefore, the character data generated by the character ROM 22 and the color data attached to the character data are applied to the display control circuit 23, and red, green, and blue video signals are created and input to the CRT display unit 24. Therefore, the command part that matches the input command will be displayed in a different color from the others. At this time, if you set the standard color to green and the change color to yellow, and input the F code as the command command, only the feed rate command part will be displayed in yellow.

Possible usage examples other than the above include the following.

(1) Sequence number color display If you simply input only the sequence number number, all sequence numbers can be displayed in different colors (two colors), and if you specifically specify the number, only the corresponding sequence number will be displayed. can.

(2) Subprogram call command color can be displayed By using M2S, which is a subprogram call command, as a designated command, only the subprogram call command can be displayed in a different color from the others.

Although coloring control is performed using the color RAM 21 in FIG. 2, it goes without saying that the present invention is also applicable to color display devices of other types.

As described in detail, the present invention colors only a designated portion of the NC command program to be displayed in a different color from the rest, so that the portion to be edited can be determined at a glance. Editing the command program is made easier (it can be done in one line).
