Abstract: 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.

Abstract: 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.
