Fault Diagnosis of Aerospace Electrical Equipment Based on Fuzzy Information Fusion

The complexity of modern aerospace electric equipment is higher than before, thus it cannot meet the need of speedy fault diagnosis to use single diagnosis pattern. Multi-resource information fusion is imported to the fault diagnosis of electronic equipment in this paper, use all stages information of multi-sensor and multiple information resource, adopt composite disposal, namely integrate the fusion of data, character and decision, and unite the fusion structure of distributed and integrated. The multi-resource fusion diagnosis structure and the fusion arithmetic are detailed. Finally, a computer simulation example is carried out; the simulation result shows that the method is effective and practical.
