Abstract

PURPOSE:To safely control a numerical controller, by displaying the operating state of a machine, etc., on a display device at a host computer side. CONSTITUTION:When an operation command or a process program is sent from a host computer 4 to the numerical controller 1 side, a command is issued from each command part 18 by referring to the display of each state display part 19 on the display device 20 similarly as an operation panel 2. At this time, an ID code is sent first, and it is possible to respond by the numerical controller only when coincidence is obtained. Therefore, it is possible to connect and control plural numerical controllers 1 to the computer 4. Also, it is possible to apply control on all of the machines simultaneously in a group by inputting information with a group level in the ID code. In such a way, an inputted signal is sent to the numerical controller 1 via a transmission line 5, and the numerical controller 1 processes the signal as if it is inputted from the operation panel 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a remote control system for a numerical control device, particularly a system for remote control using a host computer.

[Prior Art] Conventionally, for example, the following method is known for inputting and outputting an operation command signal, a program, offset data, etc. to a numerical control device from a point where the numerical control device is turned on.

(1) Offline input/output using paper tapes, floppy disks, etc.

(2) A numerical control device and a host computer are connected by a transmission line, and signals are input and output by operating the keys of both devices while timing each other.

(3) Similar to method (2), connect both devices with a transmission line, and when transmitting signals from the host computer, send in a specific format, such as by attaching a special code.

[Problem that the invention attempts to solve] These methods had the following problems.

Since method (1) is offline, it is necessary to transport the paper tape or floppy disk to the numerical control device.

Method (2) requires operation between the host computer and the numerical control device while communicating with each other using, for example, 'FLg, which is very troublesome.

Method (3) can be used even in the case of small corrections, such as Off Nanatsu!・Even for VJJ meetings where only part of the data is corrected, it is necessary to create a specific form such as adding a special code. It is also necessary for the numerical control device to decode the data in the special form. As described above, the system configuration is complicated. Furthermore, since the host computer does not know the current state of the numerical control device, it is dangerous to simply send data unilaterally from the host computer. That is, for example, if the offset data is updated while the machine is in operation, there is a risk that the machine will run out of control. ' [Means for solving the problem] A numerical control device equipped with an operation panel for commanding various operations and a CPU for processing various signals, and a host connected to the numerical control device via a transmission line. In a remote control system for a numerical control device comprising a computer, the host computer corresponds to at least a portion of each status display means on an operation panel that displays various states of the numerical control device and the machine controlled by the numerical control device. a display device having on its screen a command section corresponding to at least a part of each command means on the operation panel that commands various operations to the numerical control device and the machine; processing and outputting signals input using the control unit or the command unit so as to be the same as signals input using the corresponding status display means or command unit on the operation panel. A processing section is provided,
Furthermore, a transmitting section for transmitting the output of the processing circuit to the numerical control device via the transmission line is provided.

[Function] Referring to the status of the numerical control device, etc. displayed on the status display section of the display device on the host computer side, the signal input from the command section by the same operation as the operation panel of the numerical control device is transmitted. The signal is sent through the line to the numerical control device, which processes the signal as if it were input from an operation panel.

The host computer 4 includes a display device 20 having a screen having a command section 18 and a status display section 19, as shown in FIG. The command unit 18 executes the operation a! 0, which is a display area corresponding to at least a part of the command means 6 on I2. A temporary stop command section 23 corresponding to the button 10, a selection section 24 corresponding to the selection button 11, a reset section 25 corresponding to the reset button 12, and the like are provided. What corresponds here is
When one of these command sections is selected, for example, with a cursor, it means that the same function is performed as when the button on the operation u2 corresponding to the command section is pressed. The status display section 19 is a display area corresponding to at least a part of the status display means 7 on the operation panel 2. For example, a ready display section 35 corresponding to the ready lamp 13 and an alarm display corresponding to the warning lamp 14 are provided. 26, a return-to-origin display section 27 corresponding to the return-to-origin lamp 15, and a processing completion lamp 16.

has. The output from the code processing section 29 is inputted to the channel CH2 of the numerical control value rIt1 via the transmission line 5 by the transmitting section 30 in the host computer.

Since the transmission line 5 is a dedicated line for serial data connecting the host computer 4 and the numerical control device, a single cable is sufficient.

Since the displays and instructions on the host computer side are the same as those on the control panel of the numerical control device, operation can be facilitated. In addition, since the signals input from the display device are in the same form as the signals input from the operation panel, the host computer can operate using the code or form of the operation panel, and the numerical control device can be operated as if it were the operation panel. It can be processed as if it were input from . Therefore, the system becomes simple.
