(DE) VERFAHREN UND VORRICHTUNG ZUM ERFASSEN VON BETRIEBSDATEN EINER INDUSTRIEROBOTERANWENDUNG
(EN) METHOD AND APPARATUS FOR COLLECTING OPERATING DATA OF AN INDUSTRIAL ROBOT APPLICATION

Abstract
(EN)
A method of collecting operating data (2) of an industrial robot (4), said robot (4) having a robot control unit (6) for controlling said robot (4) and a first communication interface (8) for receiving and/or transmitting said operating data (2) from/to a central processing unit (10), said central processing unit (10) having a second communication interface (12) for receiving and/or transmitting said operating data (2) and a data mining unit (14) for analyzing said received operating data (2), is characterized by the method steps of collecting the operating data (2) of said robot (4) with a collecting frequency (15) and transmitting said collected operating data (2) to said central processing unit (10) when operating said robot (4), analyzing said collected operating data (2) and computing an indicator value (16) from said collected operating data (2) by means of said data mining unit (14), comparing said indicator value (16) with a predetermined probability threshold value (18), setting said collecting frequency (15) to a lower collecting frequency (20) if said indicator value (16) is below said predetermined probability threshold value (18), and setting said collecting frequency (15) to a higher collecting frequency (22) if said indicator value (16) is above said predetermined probability threshold value (18). The invention is further related to an apparatus for carrying out the method.
