The Reconstruction Method of Multi-Sensor Rolling Bearing Fault Signal Based on the Principle of Relevance

In order to make up for the shortcomings of incomplete signal acquired by the single sensor, utilizing multi-sensor array to acquire periodic failure signal of rolling bearing, removing redundant information, and reconstructing the incomplete fragment to a complete periodic acoustic failure signal of rolling bearing by the algorithm based on Relevance. An example of multi-sensor signal reconstruction was given to verify the validity of the method.
