Furthermore, the object description can be, for example, a sensor coupled to the test object 13 contain, for example, the input value range, the sensitivity and the weight as characteristic values. Finally, the object description can contain, for example, an algorithm used to evaluate the measured values and based on a Fourier transformation as characteristic values, for example the window length, the type of weighting function and the degree of overlap.
- the first example concerns the selection and configuration of sensors.
- the starting point when planning a test setup according to the invention is the test object.
- An electric motor that has two bearings is to be considered below as an example of a test object.
- the technical parameters that describe the electric motor are stored in a software element.
- This software element is drawn in FIGS. 2 and 3 with the term “test object description”.
- the configuration interface now transfers this element to the assistant with the call "Give sensors”.
- the wizard can now use the test item, which is an electric motor with two bearings (PK), and the following measuring points are configured: radial housing, radial bearing and axial bearing2.
- the parameter for sensor selection is generated, reads suitable sensors from the hardware catalog (HWP), inserts the software sensor elements into the process control and fills them with the specific sensor data. He then returns the changed sequence control to the configuration interface. This can now call the wizard again, but this time with the call "Give signal adjustment for sensors”.
- HWP hardware catalog
- the second example concerns the selection and configuration of an analysis method and its parameters. If a quality error class QFK k is configured, e.g. the quality 14 error class "grazing noise", at least one suitable analysis method must now be sought, with which their detection and evaluation is possible. To do this, the configuration interface calls the assistant with the call "Give analysis methods and their parameters" and the sequence control. Based on rules, the knowledge base activates a suitable analysis method AV j for the currently configured quality error class QFK k. As an example, the quality error class "Cepstrum" can be activated. The parameters needed to calculate a cepstrum are generated by the
- the invention thus relates to a system 8, 9 and a method for configuration and / or parameterization of a diagnostic device 4 for objects to be tested 3.
- the system consists of a first data object 1 with a collection of technological test object parameters PK1, PK2 ... PKz des Object 3 to be tested and its components 3a..3n, from a second data object 2 with a collection of technological parameters HWType I, HWType II, ... of hardware components of the diagnostic device 4, from a first program object 5 with data records 7 for the assignment of at least one of Test object parameters PKl, PK2 ... PKz and technological parameters HWType I, HWType II, ...
