Abstract

The invention provides a system attached to a laser beam machine for supporting failure prognosis, warning and restoration operation by monitoring the status of the machine. A laser beam machine 1 has a pallet 20 supported on a bed 10, and subjects a work W₁ to laser processing. The management unit 100 attached to the machine 1 is connected via an internet connection to a server 2 at a service center, and also transmits the status of the machine to a cellular phone 3 or a personal computer 4 of an administrator. The management unit 100 has a large image display unit 200, through which the status of the machine is output via messages and audio so as to notify the operator of necessary restoration operations. The procedures of restoration operations are output via image and message, supporting the operation of the operator.

Claims

1. A support system for failure prognosis, warning and restoration operation of a machine comprising a machine and a management unit attached to the machine;

the management unit comprising a communication means for communicating with the machine, an image display unit for displaying the status or the like of the machine, an audio output means, and a communication means for communicating via a public line with a remote server;

the management unit further having a function to output the status of the machine on the screen as message, display in color and output via audio a warning level when failure occurs, and a function to output a procedure for restoring the failure via image and message.

2. The support system for failure prognosis, warning and restoration operation of a machine according to claim 1, wherein

the management unit has a function to keep the lapse time of each periodic inspection item of the machine, a function to compute a ratio of the lapse time and a predetermined time set in advance for each inspection item, and a function to display a warning on an image display when the ratio reaches a predetermined ratio and to notify the same to a cellular phone of an operator.

3. The support system for failure prognosis, warning and restoration operation of a machine according to claim 1, wherein the machine is a laser beam machine.
