Abstract

PURPOSE:To display picture data which are required for the working process of a numerical controller and to be displayed without complicated key operations by automatically displaying picture data specified by a screen control command. CONSTITUTION:A CPU 5 stores a working program 7 including a screen control command SCRN(n) in a memory 8. Moreover, the CPU 5 reads out the working program 7 from the memory 8 and discriminates whether or not the read-out command is a screen control command. When the read-out command is a screen control command 16, the CPU 5 selects a screen number (n) which is a parameter from the screen control command SCRN(n) and reads out picture data corresponding to the screen number (n) from a memory 9. Then the CPU 5 stores the picture data in a picture data memory 6. Thereafter, the CPU 5 causes the picture data stored in the picture data memory 6 to be displayed on a display screen 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device for a numerical control device, and more particularly to a display device for a numerical control device that allows easy selection of display screens.

[Prior Art] FIG. 4 is a block diagram of a display device of a conventional numerical control device. In FIG. 4, (1) is a CRT display screen that displays display screen data, (2) is an operation keyboard, (
3) is the main body of the control device, (4) is the interface between the operation keyboard (2) and the main body of the control device (3), and (5) is the central processing unit (hereinafter referred to as CPU) that creates screen data for display.
, (6) is a display screen data memory that stores display screen data created by the CPU (5).

Next, the operation of the display device of the conventional numerical control device will be explained. First, key information (screen number) input using the operating keyboard (2) is input to the CPU (5) via the interface (4).

The CPU (5) creates predetermined display screen data based on the key information and stores it in the screen data memory (6).

Further, the CPU (5) causes the data stored in the screen data memory (6) to be displayed on the display screen (1).

[Problems to be Solved by the Invention] By the way, the display device of the conventional numerical control device having the above-mentioned configuration does not allow key information to be displayed on the display screen (1) in each processing process of the numerical control device to be displayed on the operation keyboard (2). had to be selected by key operation.

For this reason, there is a problem in that the more complex the screen configuration, the more key operations are required and the more troublesome it becomes.

The present invention has been made to solve the above problems,
It is an object of the present invention to provide a display device for a numerical control device in which a display screen can be selected from other than an operation keyboard (2).

[Means for Solving the Problems] A display device for a numerical control device according to the present invention includes a first storage device that includes a screen control command and stores a machining program to be executed by the numerical control device; A second storage means stores the screen data specified by the command, and if there is a screen control command when executing the machining program, the second
and processing program execution means for reading and displaying screen data specified by the screen control command from the storage means.

[Operation] In the display device of the numerical control device having the above configuration, when the machining program execution means includes a screen control command in the machining program, the display device displays screen data specified by the screen control command.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of a display device of a numerical control device according to an embodiment of the present invention. In Fig. 1, (1) is the CRT display screen that displays display screen data, (2) is the operation keyboard, (3) is the control device main body, and (4) is the operation keyboard (2) and the control device main body ( 3) is an interface with, (5) is a CPU that creates screen data for display, (
13) is a display screen data memory that stores the display screen data created by the CPU (5), and (7) is a screen control command! 1licRN (n), (8) is a memory that stores the machining program (7), and (9) is a memory that stores each screen data to be displayed on the display screen ihi (1).

Screen control command SCI? N(n) is a command to read screen data corresponding to parameter n from the memory (9).

Next, the operation of the display device of the numerical control device shown in FIG. 1 will be explained with reference to the flowchart shown in FIG.

(1) Step SI CPU (5) executes screen control command 5 as shown in FIG.
The machining program (7) including CRN (n) is stored in the memory (
8) (step Sl).

(2) Steps 82 to S4 The CPU (5) reads the machining program (
7) and determines whether the read command is a screen control command (step S2).

CPU (5) reads out the command as screen control command (1
6), select the screen number n, which is a parameter, from the screen control command 5CRN(n), step S3);
The screen data corresponding to screen number n is read from the memory (9) and stored in the screen data memory (6) (step 84).

(3) Step S5 The CPU (5) displays the screen data stored in the screen data memory (6) on the display screen (1) (Step S5).

Note that when there is no screen control command 5CRN(n), the currently displayed screen data is displayed without changing the display screen.

(4) Step S6 CPU (5) repeatedly executes steps 81 to S5 until it reads an end command indicating the end of machining program (7).

Although the screen control command 5CRN(n) is used in this embodiment, other unique commands (arbitrary character strings) may be used, and the same effects as in this embodiment can be achieved.

[Effects of the Invention] As explained above, according to the present invention, when the machining program includes a screen control command, the machining program executes displaying the screen data specified by the screen control command. It is possible to obtain a display device for a numerical control device that can display screen data necessary for the processing process of the device without complicated key operations.
