Method and device for performing a measurement method for the data-based description of a system behavior of a technical system

摘要

The invention relates to a method for determining a data-based system model, which describes a technical system (5) functionally by assigning an input point to one or more output variables, with several measurement runs being carried out with the following steps in each case: Measuring point set with several measuring points, the measuring points each defining one or more measuring input points; - measuring (S3, S23) of the technical system (5) according to the specified measuring point set; - creating (S6, S7; S26, S27) or updating the data-based system model and a data-based security model depending on measurement point data that correspond to the measurement input points and the corresponding associated measurement output variables; a set of measuring points to be measured next is specified as a function of the last created or updated data-based system model and data-based security model (S8, S28).
