VIBROMOD - An experimental model for Change Detection and Diagnosis Problems

Dorel Aiordachioaie, Theodor D. Popescu

Abstract

The objective of the paper is to introduce an experimental model (VIBROMOD) designed for solving change detection and diagnosis problems in various fields of applications, mainly vibration engineering. The hardware structure contains two basic levels: one for fast computations and alarms, which processes data in a matter of hours, and, an upper level, for large-scale monitoring and statistical computation of moments, over a time span of days and months. The algorithms running on VIBROMOD are coming from a specialized toolbox, which contains classical methods, based on statistical signal processing techniques, but also some advanced methods, based on time-frequency and information transforms. The monitored interaction between VIBROTOOL and VIBROMOD is the goal of a large project called VIBROCHANGE, and allows for rapid implementations, checking and testing of various algorithms and the development of benchmarks as well, for change detection and diagnosis problems.
