摘要

In order to degrade the uncertainty and improve the veracity of diagnostic results, the diagnostic method based on fusing information which derives from each channel is proposed to utilize the diagnostic knowledge adequately and solve the contradiction between leaving much diagnostic knowledge unused and the lack of diagnostic knowledge Firstly the thought of diagnostic information fusion is presented, and the diagnostic model is established based on the thought. Then, in order to conquer the dimension disagreement of all kinds of diagnostic information to make them fuse together and gain its basic belief assignment and uncertainty probability in D-S evidence theory, the information must be made normalized. Finally, fusion arithmetic of D-S evidence theory is provided and a certain train automatic door is taken for example to verify the proposed method.
