Abstract

Aiming at the uncertainty of the results obtained by using single sensor and single algorithm in the process of machine state identification, the DS evidence theory is introduced. Firstly, the basic probability assignment (BPA) is constructed according to the classification results of the support vector data description (SVDD) and BP neural network. Then the BPA of the two algorithms are fused according to the evidence rule, and the output result of the single sensor is obtained. Finally, the decision conclusion is obtained according to the fusion of multi sensor classification results. It can be seen from the bearing experiment that the uncertainty of decision is greatly reduced after information fusion, which can make full use of the complementary information of each signal sensor to improve the accuracy and credibility of the decision.
