INTRINSIC METHOD FOR MONITORING INDUSTRIAL APPLICATION FOR VIRTUAL DIAGNOSTICS

摘要

The Internet of Things (IoT) refers to a network and virtual representations of individual objects (e.g. machine part) in an internet-like structure. This representation enables the comparison of the behavior of the real world object to a virtual counterpart. On the virtual counterpart the reactions of loads or an estimation of remaining life time among other aspects can be simulated. To realize those industrial visions each object's needs to have cheap and reliable systems that monitor and record the object conditions during the full lifetime. Only with these data a mapping of the virtual object will be possible and, therefore, an estimation of the remaining life can be provided. This paper will describe a method that covers these challenges on two sample applications. 1. Condition monitoring of a wind turbine epicyclic gear, especially the planet meshing and the planet bearing using a measurement system mounted on the planet carrier. 2. Condition monitoring of a single centered chain strand built in an armored face conveyor, by use of a special measurement chain link.
