基于D-S证据理论的液压泵故障诊断

Hydraulic Pump Fault Diagnosis Based on D-S Theory Evidence

介绍了D-S证据理论的基本概念、基本理论,讨论了基于D-S证据理论信息融合的故障诊断方法,并将其应用于液压泵故障诊断中。结果表明基于D-S证据理论的信息融合诊断方法可以充分利用多个传感器信息的冗余性与互补性,实现比单一传感器神经网络诊断更为准确和可靠的诊断结果。

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.
