摘　　要：DS证据推理理论由于其能很好融合多传感器数据和区分不确定与不知道的问题,因而被广泛应用于故障诊断过程中。但由于其不能很好的处理冲突项,在应用中受到限制。为解决此问题,通过建立传感器间支持信任矩阵,重新赋予加权系数,经过仿真表明此方法很好的解决了DS理论中的冲突问题,提高了故障诊断正确率。The DS proof theory is widely used in Fault Diagnosis because it can fuse data from multiple sensors and distinguish the statement of unknown and undefinite. But its applying is limited since its disability on dealing with the conflict proof. So supportive matrix between sensors is established in order to solve this problem. This method can solve the conflict problem in DS theory very well through simulink.
