摘要：
This paper presents the design of a diagnosis procedure in order to improve the reliability of embedded systems subjected to vibration. This procedure is based on the use of wavelet transform of the vibration signals. The transformation provides the wavelet coefficients needed to calculate indicators such as energy and entropy. Artificial neural networks provide a rapid detection of the presence of structural defects. Results have been implemented and verified in real time on a dSPACE platform.
