The invention relates to an acoustic diagnostic system and an associated method, wherein the system includes a sensor mechanism to convert mechanical vibrations into electrical signals. The acoustic diagnostic system furthermore includes a signal conditioning unit to amplify and low-pass filter the electrical signals and an analog/digital converter to convert the amplified and low-pass filtered signals into discrete digital data. In addition, a signal processing unit, which performs signal analysis, extraction of characteristics, and classification of error classes and/or quality classes, which are associated with a respective test object of the digital data, is provided. Finally, the acoustic diagnostic system includes an archive to automatically archive an occurrence and a frequency of the error classes and/or the quality classes. The diagnostic system preferably includes controlling means that control the production process for the manufacture of the test object.

Acoustic diagnostic system and associated method

The invention is directed to a system and a method for the configuration and/or parameterization of diagnostic devices for test objects. The system includes a first data object having a collection of technological test object parameters of the test object and its components, and a second data object having a collection of technological parameters of hardware components of the diagnostic device. The system further includes a first program object containing data sentences for the assignment of at least test object parameters and technological parameters of hardware components, and a second program object for processing the data sentences assigned in the first program object. Via the data and program objects, a knowledge base is created that results in a configuration mainly automatically controlled by the knowledge of the system and/or parameterization of the diagnostic device including the test structure and evaluation. In this manner, the cost of such preparations is significantly reduced.
