Method, Apparatus and System for Detecting Abnormal Operating States of a Device

A method for detecting abnormal operating states of a device includes obtaining model data to the device that is representative of operating states to be expected for at least one component of the device. The device collects measurement data that is representative of an actual operating state of the component of the device. The device ascertains comparison data on the basis of the model data and the measurement data, where the comparison data is representative of an expected operating state. The method includes using the comparison data and the measurement data as a basis for determining whether there is a discrepancy between the actual operating state and the expected operating state. The method further includes attributing an abnormal operating state to the at least one component in a manner corresponding to a time of collection of the measurement data on the basis of the discrepancy.
