A System Concept for Embedded Condition Monitoring of Electronic Sensor Modules

In this paper, a system concept for embedded real-time data acquisition and condition monitoring of a safety-critical sensor module is presented. Based on the expected main life-cycle loads, suitable sensors have been selected for in-situ monitoring of possible failure precursors. Derived from previous considerations, the implementation of special monitoring subsystems for thermo-mechanical stress and signal quality is described. Eventually, a concept for real-time data acquisition is presented, which also lays the foundation for the collection of a training dataset for data-driven condition monitoring approaches of the investigated sensor module. A high priority has been set to a reusable design so that system concept, hardware and firmware can be used for training data acquisition as well as for validation of the final, data-driven condition monitoring algorithms.
