Abstract

To monitor or control a machine, current operating signals are captured continuously, and a current operating state is measured continuously. On the basis of the captured operating, a simulated operating state is determined continuously by a concurrent simulator. In addition, upon detection of a difference between the simulated operating state and the measured operating state, a difference pattern that quantifies the deviation or a change in the measured operating state is compared with a plurality of specified difference types which are characteristic of a modification of the machine or a machine operation, and each of the difference types is assigned a difference-type-specific simulator variant. Depending on the result of the comparison, one of the difference types is then selected. On the basis of the simulator variant assigned to the selected deviation type, the concurrent simulator is adapted, and the machine is monitored or controlled using the adapted concurrent simulator.

Dependent claims

A computer-implemented method for monitoring or controlling a machine, wherein during operation of the machine

a) present operating signals of the machine are continually recorded and a present operating state of the machine is continually measured,
b) a concurrent simulator takes the recorded operating signals as a basis for continually ascertaining a simulated operating state of the machine,
c) detection of a difference between the simulated operating state and the measured operating state results in a difference pattern, which quantifies the difference or a change in the measured operating state, being compared with multiple predefined difference types that are characteristic of a modification of the machine or of machine operation and that each have an assigned difference-type-specific simulator variant,
d) the comparison result is taken as a basis for selecting one of the difference types,
e) the concurrent simulator is adapted on the basis of the simulator variant assigned to the selected difference type, and
f) the machine is monitored or controlled by the adapted concurrent simulator.
