Abstract
Aimed at the base band problem that it’s hard to evaluate exactly for some fault factors by using math model because of fuzziness, put forwards base band fault diagnosis method based on fuzzy fault tree. Based on base band fault theory, the method uses fault tree analysis method to establish fault tree by taking based band signal unlock as research object. And then the qualitative and quantitative analysis of the fault tree is accomplished ,by establishing models such as minimal cut set, exact and fuzzy fault probability of bottom things, and importance analysis of bottom things. Finally, the feasibility of models is validated by data calculating. The study provides the base for developing the expert system of base band fault diagnosis.关键词
