Device for detecting the operating state of a working machine

摘要

The device has one or multiple sensors (70,74,82) for providing an output value with respect to an actual parameter of a component of a working machine. A processing unit (88) is programmed to derive the elements of the emission probability matrix from the measured values of the sensors. The processing unit is programmed to derive the elements of the emission probability matrix from fuzzified measured values from sensors, where the fuzzifield measured values are fed to the hidden-markov-model (94) as monitoring.
