基于信息融合的观点解决大型设备故障的综合诊断问题。从证据合成的基本理论出发，分析了故障综合诊断中证据的支持和冲突，以风机液压制动系统的故障诊断为例，表明证据理论可以提高故障判决的准确度。

英文摘要：

The problem of integrated fault diagnosis of large-scale equipment is solved in this paper based on the information fusion theory. From the basic principle of information fusion point of view, we carry out the analysis on the support of the proof and the conflicts during synthesized fault diagnosis, and take the fault diagnosis of the fans of wind turbine braking systems as an example, showing that the evidence theory can improve the accuracy of fault diagnosis.
