| Abstract: | The basic concept and basic theory about the theory of D-S evidence is introduced,the fault diagnosis method based on the D-S evidence theoretical information fuses is discussed and applied in the fault diagnosis of the hydraulic pump.The result indicates that the information fusion diagnosis method based on theory of D-S evidence can use the complementary and redundancy of multi-sensor information fully,realized more accurate and reliable results than single sensor nerve network. |
