DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a schematic configuration of the present invention. The internal storage device 4 stores various data (application programs, parameters, data, etc.) in the system of the numerical control device. As the internal storage device, a writable storage device such as a memory backed up by a battery, an EEPROM, or a flash ROM that can retain data even when the power is turned off is used.

The data exchange device 1 is a device for exchanging various data stored in the internal storage device 4, and is attached to the system when exchanging data. The data exchange device 1 stores various data in the internal storage device 4
The data to be transferred is stored when the data is installed, and the data has a free space to store the data when the various data stored in the internal storage device 4 is saved. A hard disk drive or a memory card (also called a RAM card) is used for the data exchange device 1.

A data transfer command file 7 is stored in the data exchange device 1 as required. this is,
This is a file in which a procedure for data transfer between the internal storage device 4 and the data exchange device 1 is written. By executing this data transfer command file 7, data transfer can be automatically performed.

The data exchange device detecting means 2 detects that the data exchange device 1 is mounted when the power is turned on. This is a function performed by the processor. When the power is turned on, the processor confirms the system configuration and confirms whether the data exchange device 1 is attached. If the data exchange device 1 is not attached, the system is started up as usual and the system is ready for use. If the data exchange device 1 is attached, the control is transferred to the data transfer management means 3.

The data transfer management means 3 makes the system ready for data transfer when the data exchange device 1 is detected. This is a function performed by the processor executing a program for data transfer.

The data transfer management means 3 first searches the data transfer command file 7. When the data transfer command file 7 is detected, that file is executed. As a result, data is automatically transferred.

When the data transfer command file 7 is not detected, the data transfer operation screen is displayed on the display device 43. Then, the operator can input data from the keyboard 44 to transfer data between the data exchange device 1 and the internal storage device 4.

After the data is transferred, the normal operation state is set. The normal operating state mentioned here is a state in which the software that should be started up when the power is turned on without mounting the data exchange device is executed and the device can be used normally.

FIG. 2 is a diagram showing the configuration of a numerical controller for implementing the present invention. The concept of the numerical control system is the same as in FIG. FIG. 2 is roughly divided into a numerical control section and a man-machine controller section. In the numerical control unit, the processor 11 controls various devices via the bus 19, and in the man-machine controller unit, the processor 31 controls various devices via the bus 39. The numerical control unit and the man-machine controller unit are bus 2
9 are connected to each other, and data is transmitted and received via the bus 29.

In the numerical control unit, the processor 11 uses R
The entire numerical control unit is controlled according to the system program stored in the OM 12. The RAM 13 stores various data or input / output signals. A CMOS memory is used as the non-volatile memory 14 and is backed up by a battery, and stores parameters, pitch error correction amounts, tool error correction amounts, and the like to be retained even after the power is turned off.

The axis control circuit 21 receives the axis movement command from the processor 11 and outputs the axis command to the servo amplifier 22. The servo amplifier 22 receives the movement command and drives the machine tool 50 to drive the servo motor. A PMC (Programmable Machine Controller) 23 receives a T function signal (tool selection command) and the like when executing an NC program. Then, these signals are processed by the sequence program, and the signals are output as operation commands, and the machine tool 5
Control 0. Further, it receives a status signal from the machine tool 50, performs a sequence process, and transfers a necessary input signal to the processor 11.

Further, the input / output interface 46 connected to the bus 19 controls input / output of data including NC between external devices such as FDD (floppy disk device), printer, or PTR (paper tape reader). To do.

In the man-machine controller section,
The processor 31 executes the interactive processing program stored in the ROM 32, and in the interactive input screen, MDI / C in a menu format for work or data that can be set.
It is displayed on the display device 43 of the RT (Manual Data Input / Cathod Ray Tube) unit 40. In addition, a machining program is created from the data thus input, and the starting trajectory of the entire tool is displayed as a background animation. The RAM 33 stores various data for dialogue and the like. The nonvolatile memory 4a is a memory using CMOS and is backed up by a battery, and stores application programs, machining programs, etc. that should be retained even after the power is turned off. VRAM
The (video RAM) 35 is a RAM that can be accessed at high speed, and stores graphic data for displaying animation when performing a cutting simulation of the machine tool 50 based on a machining program stored as an NC sentence in the non-volatile memory 4a. To be done. The graphic control circuit 36 converts the graphic data stored in the VRAM 35 into a display signal and outputs it to the MDI / CRT unit 40.

Furthermore, when exchanging data, the SCS
A SCSI standard HDD 1a is mounted via an I (Small Computer System Interface) standard interface 37. This SCSI standardizes the method of accessing a peripheral device of a small computer by the American National Standards Institute. The HDD 1a stores data to be transferred to the non-volatile memory 4a or the like, or has an empty area for storing the data in the non-volatile memory 4a. A data transfer command file 7 (shown in FIG. 1) for automatically transferring data is also stored as necessary. In addition, the program for data transfer is also H
It is stored in DD1a. This avoids using extra memory in the numerical controller.

Further, the MDI / CRT unit 40 includes
Graphic control circuit 41, switching device 42, display device 4
3, a keyboard 44, and a software key 45 are provided. The graphic control circuit 41 converts a digital signal output from the processor 11 or the like into a signal for display and outputs the signal. The switch 42 switches the display signal output from the graphic control circuit 36 formed in the man-machine controller section or the graphic control circuit 41 in the MDI / CRT unit 40 and supplies it to the display device 43. A CRT or a liquid crystal display device is used as the display device 43. The keyboard 44 comprises symbolic keys, numerical keys, etc.
Enter data using these keys. The software key 45 is a command key whose function is changed by a system program or the like, and the function name or the like is displayed on the display device 43.
Is displayed at a predetermined screen position.

When transferring data between the HDD 1a and the internal memory such as the non-volatile memory 4a, a data transfer operation screen is displayed on the display device 43 and the keyboard 4 is operated.
Data can be transferred by key input from 4.

FIG. 3 is a view showing a data transfer operation screen displayed on the display device 43. This data transfer operation screen is displayed when the SCSI interface 37 and the HDD 1a are mounted on the man-machine controller and the data transfer command file 7 does not exist in the HDD 1a. On this data transfer operation screen, maintenance work such as various environmental settings can be performed in addition to data transfer.

The data transfer operation screen has a menu format. When the numerical values of the items displayed in the main menu are entered from the keyboard 44, the submenu of the specified items is displayed, and the items in the submenu are further selected. By doing so, the data transfer work can be executed. This main menu has four items. 1
The second is installation, and data to be stored in the nonvolatile memory 4a can be installed from the HDD 1a. The second is file operation, which can save, delete, and dump files stored in the HDD 1a and various memories. With these two functions,
It is possible to perform transfer work such as data installation and save. The third is the environment setting, and the RAM 33 (see FIG.
Various environment settings such as the area setting (shown in FIG. 4) can be performed. Finally, there is an end, and it is possible to enter the normal operation state by selecting this item.

FIG. 4 is a flow chart showing the processing procedure of the present invention. This flow chart explains the operation in the man-machine controller section of the numerical controller shown in FIG. [S1] The power is turned on. [S2] The system of the man-machine controller is initialized. The contents of the initialization include the parity check of the ROM 32, the parity check of the RAM 33, and the SC.
SI interface 37 and graphic control circuit 36
Initialization, etc. [S3] It is determined whether the HDD 1a is mounted. If it is attached, the process proceeds to step 4, and if it is not attached, the process proceeds to step 9. [S4] HDD 1 for data transfer ready
Access to a is started. [S5] The data transfer command file in the HDD 1a is searched. If the data transfer command file exists, the process proceeds to step 8, and if not, the process proceeds to step 6. [S6] The data transfer operation screen shown in FIG.

[S8] The data transfer command file in the HDD 1a is executed to transfer the data. [S9] The system of the man-machine controller is brought into a normal operating state.

In this way, when the power is turned on, the HDD 1a is
If is installed, the data can be transferred without pressing a special key, and the operator does not have to be forced to do extra work.

Furthermore, by preparing the data transfer command file, the data transfer work can be automatically performed. Once the data transfer command file is prepared, the data transfer work can be performed simply by mounting the HDD 1a thereafter. it can. Therefore, the burden on the worker is greatly reduced, and the possibility that the worker will make a work error is reduced.

Since all the data transfer work is performed automatically, if the worker who creates the data transfer command file is familiar with the work contents, the worker who actually performs the work at the time of data transfer will know the work contents. You don't need to be aware. Therefore, even if the work content is complicated, no special education is required, and the data transfer can be performed by only the simple work.

Incidentally, the numerical control device becomes complicated, and the internal storage device in the numerical control device is a flash ROM or EEPR.
When the OM or the built-in HDD is diversified, the contents of the data transfer work will be diversified, so that the worker can carry out the transfer work without being aware of the work contents, especially in order to reduce work mistakes and improve work efficiency. It is valid.

In the above description, the data exchange device is the hard disk drive, but it may be a memory card. The use of the memory card facilitates mounting of the device. Moreover, unlike a hard disk drive, there is no need to be careful about vibrations, and handling precautions can be reduced.

In the above description, the implementation in the man-machine controller section has been described. However, the numerical control section is also equipped with a data exchange device, and an internal storage device (flash ROM, EEPROM, battery-backed memory). Data is installed or saved, and the present invention can be carried out in the same manner as in the man-machine controller section.

[0040]

As described above, according to the present invention, the data exchange device detecting means for detecting that the data exchange device is mounted is provided, and the data can be transferred when the data exchange device is detected. Since the system is started in this state, the work to be performed by the worker can be reduced and the work becomes easier.

Further, since the data transfer is automatically performed by preparing the data transfer command file, the burden on the operator can be further reduced and the working efficiency can be improved.
