Abstract

PURPOSE:To control freely a voice output by a user writing a predetermined voice output information in a memory area in which the voice output information of a memory means is written. CONSTITUTION:An operator pushes a dry run of an operating switch 9 of an operating board 7 of a machine. This signal is delivered to a CPU2a in a programmable controller 2. When a maker desired to output of a voice of this signal, a flag dry run of a voice output information area 12a in a window 12 is turned on. A CPU1a of an NC side 1 sees this window periodically and when it detects the flag standing, it outputs the voice of the dry run to a speaker 8 and at the same time, turns off the flag. The CPU2a inputs and outputs contact signals of a high power electric board 10 of a machine side. By a combination of these signals and a working program it is judged that an operating is completed, and when a corresponding flag operation in the area 12a is completed, a repeat is turned on. When the CPU1a detects it, the operation completion is repeatedly outputted by voice and continued until it is reset.

Description

[Detailed description of the invention] This relates to the audio output function.

[Conventional technology]

FIG. 3 is a block diagram showing the main parts of a conventional numerical control device. In the figure, 1 is a numerical control device main body (numerical control device in a narrow sense, hereinafter referred to as NG), 2 is a programmable controller (hereinafter referred to as P) that directly controls machine tools, etc.
The above NC1 has a central processing unit (hereinafter referred to as CPU) la in which a control program including an audio output function is fixed by the NC manufacturer, and PC2 has a central processing unit (hereinafter referred to as CPU) la in which a control program including an audio output function is fixed by the user. , that is, it has CPυ2a open to machine manufacturers. 3 is the above NCI and P
A conventional narrow window between C2 and this window 3 is a storage means in which control information for controlling the machine is read and written by each of the CPUs 1a and 2a of the NCI and PO2;
For example, it is configured with a shared memory or a 2-PORT memory.

4 is an NG operation board equipped with an operation button 5 and a CRT display device 6, etc.; 7 is a machine operation board equipped with a speaker 8 and operation switches 9, etc.; 10 is a machine-side power panel; A numerical control device 11 is configured.

Conventionally, there was no audio output related to the signal exchange between the manufacturer's fixed NCI and the PO2, which was open to the user and allowed the customer to create a sequence program to control the relay of the machine side power panel 1α. Ta.

Therefore, the conventional audio output function was completely controlled by the cpUla control program in the NCI, or by the CPU control program if the NC operation board 4 included a CPU.

Below, the operation will be explained using an example of the audio output function in the above-mentioned conventional technology.

When the operator presses the operation button 5, the CPU in the NCI cpUla or the NC operation board 4 detects which operation button has been pressed and outputs a corresponding sound through the speaker 8 to notify the operator.

Furthermore, when the machine is in an emergency situation such as at the end of its stroke, a contact signal is taken from the machine side power board 10 to PO2, and this signal is further passed to the NCI via the window 3, and the CPU 1a outputs the corresponding sound. It is output through the speaker 8 to notify the operator.

[Problem that the invention seeks to solve]

Conventional numerical control devices have a narrow window 3 between the NCI and PO2 as described above, and are not configured so that only the information that controls the machine is transmitted, and the information that controls the audio output is not transmitted. Only the sound within the range allowed by the control program in the NC operation board 4 can be output, and it has been difficult to output the sound from the operation switch 9 of the machine operation board 7, which differs depending on the machine manufacturer. Further, there was a problem in that even if the machine manufacturer tried to output audio using a specific combination of the operation switch 9 and the machine side power panel IO, it would not be possible.

This invention was made to solve the above-mentioned problems, and aims to provide a numerical control device that allows a user to freely output audio using the control program of the CPU 2a in the PO2.

[Means for solving problems]

The numerical control device according to the present invention includes each C in an NC and a PC.
The storage means in which control information is read and written by the PU is provided with a storage area in which audio output information is read and written.

[Effect]

In this invention, predetermined audio output information is written in a storage area where audio output information is read and written in the storage means by a control program of the CPU in the PC, and this audio output information is read out by the CPU in the NC. A corresponding audio output is made.

〔Example〕

The present invention will be explained below based on the embodiments shown in FIGS. 1 and 2. FIG. 1 is a block diagram showing the main parts of the embodiment, and the same reference numerals are used for the same or equivalent parts as in the conventional example shown in FIG. 3, and the explanation thereof is omitted. In the figure, 12 is N
This is a window expanded by this embodiment between the CI and the PC 2, and the shared memory as a storage means constituting this window 12 or the 2-PORT memory includes, in addition to the conventional storage area where control information is read and written. An audio output information area 12a as shown in FIG. 2 is provided as a storage area in which audio output information is read and written, making it possible to transmit audio output information.

Next, the operation will be explained. Operator uses machine operation board 7
Assume that the switch 9, for example, "dry run" is pressed. This signal is delivered to the CPU2a in the PO2 directly or via the NCI. If the machine manufacturer wishes to output this signal as an audio signal, the flag "dry run" in the audio output information area 12a shown in FIG. 2 in the window 12 is turned on. The CPU 1a on the NCI side regularly checks this window 12, and when it detects that the "dry run" flag is set, it outputs a voice saying "dry run" to the speaker 8 and simultaneously turns off this flag.

In addition, the CPU 2a in the PO 2 also inputs and outputs contact signals from the machine-side power panel 1°, and when it is determined, for example, "work completed" based on a combination of these signals and the computer program, the audio output information area shown in Figure 2 is output. 12a, turn on the corresponding flag "Work completed" and "Repeat". NC1 side +7)
When the CPU 1a detects that the "work completed" flag is set, it outputs a voice saying "work completed" to the speaker 8. Furthermore, if the "repeat" flag is set, this flag will not be cleared until the operator presses the "reset" switch in the machine operation board 7, and the "work completed" will be repeated.
Continues audio output.

In addition, in the above embodiment, a method was shown in which NCI prepares a menu such as "dry run" and "work completed" as an example of audio output information, but if sound quality is not an issue, "A" is used.
"I""U"・--"NJ, rAJrBJ rC"--
Words such as rZJ may also be used. These are the NCI side and PO
It is optional depending on the agreement between the two sides, and the point is that the NCI side and the PO
It is sufficient that there is a transmission path for audio information on the second side.

〔Effect of the invention〕

As explained above, according to the present invention, by providing a storage area in which voice output information is read and written in the storage means in which control information is read and written by each CPU in the NC and PC, the PC side, that is, the user This has the effect of providing a numerical control device that allows a person to freely control audio output.
