Definitions
- the present invention relates to a remote diagnosis method of a CNC for diagnosing failure of a numerical control device (CNC), and more particularly to a diagnosis method of a CNC which performs a diagnosis by connecting a numerical control device and a host computer via a network.
- CNC numerical control device
- the present invention has been made in view of such a point, and an object of the present invention is to provide a diagnostic method of CNC by connecting a numerical controller and a host computer via a network.
- a host computer and a numerical control device are connected via a network, and a failure diagnosis program is provided by the host computer.
- the present invention provides a CNC diagnostic method characterized in that the numerical control device is downloaded to the numerical control device and a failure diagnosis of the numerical control device is performed.
- the host computer downloads a diagnostic program for failure diagnosis to the numerical controller, executes the failure diagnosis, and transfers necessary data to the host computer.
- FIG. 1 is a block diagram of an embodiment of a CNC diagnostic method according to the present invention.
- FIG. 2 is a block diagram of a numerical controller according to the present invention.
- BEST MODE FOR CARRYING OUT THE INVENTION hereinafter, an embodiment of the present invention will be described with reference to the drawings.
- FIG. 1 shows a block diagram of an embodiment of the CNC diagnostic method according to the present invention.
- 10 is a host computer section
- 11 is a host computer
- 12 is a communication port.
- 5 1 is modeled.
- Numerals 20, 30, and 40 are numerical control units (CNCs) coupled to the numerical control machine, and coupled to modems 52, 53, and 54, respectively, to provide communication lines 55, 56, and 54. It is connected to the modem 51 of the host computer via 57.
- CNCs numerical control units
- the network between the host computer and the numerical controller uses the MAP (ManufactuirngAutomationdProtocoll) which is currently in use.
- the communication lines 55, 56, and 57 that make up the network use wire, and coaxial cables use optical fibers.
- a combined machine may be used for the modem 51 and the like.
- a failure diagnosis program is downloaded from the host computer 10 to the corresponding numerical control unit. Then, data required for diagnosis is transferred to the host computer.
- the service engineer transfers these data to the host computer screen. You can request a special data transfer if necessary.
- FIG. 2 shows a block diagram of the numerical control device of the present invention.
- reference numeral 20 denotes a numerical controller (CNC)
- reference numeral 61 denotes a processor that controls the numerical controller.
- 62 is R 0 M in which the system program is stored
- 63 is R AM in which the system program is loaded and other data is stored.
- Reference numeral 64a denotes an operation key
- reference numeral 64b denotes a display device
- reference numeral 65 denotes a CM0S constituting a battery-packed nonvolatile memory.
- 66 a is a PMC (programmable machine 'controller) built in the numerical controller 20 and controls the machine side with a sequence program created in ladder format.
- 6 6b is obtained from the IZO unit, and the power board on the machine side is an interface for input and output to the operation panel.
- Reference numeral 67 denotes a processor for failure diagnosis.
- Reference numeral 68 denotes a RAM for storing a failure diagnosis program.
- the processor 67 is used in accordance with the diagnostic program stored in the RAM 68. Perform a diagnosis. This is because, when a failure occurs, the failure cause may be found in the processor 63 or the RAM 63 or the like, and therefore, a processor and a RAM dedicated to failure diagnosis are provided.
- 69 is a communication port, receives a diagnostic program, and converts it into an internal signal.
- 52 is a modem, and 55 and 56 are communication lines.
- 71 to 75 are axis control circuits for controlling the position of each axis.
- the servo amplifiers 81 to 85 drive the servo motors 91 to 95.
- the host computer and the numerical control device are connected to each other via a network to perform fault diagnosis. Diagnosis can be performed, failure recovery time is reduced, and cost is reduced.

Abstract
Lorsqu'une panne se produit dans l'une quelconque des unités de commande numérique (20, 30 et 40), un ordinateur hôte (11) charge dans l'unité de commande numérique un programme de diagnostic de la panne, et effectue ledit diagnostic. Les données requises sont ensuite transférées depuis l'unité de commande numérique vers l'ordinateur hôte (11). Par conséquent, un technicien de maintenance peut déterminer la panne survenue dans l'unité de commande numérique grâce à l'analyse des données visualisées à l'écran de l'ordinateur hôte (11).
