| 摘 要： | 由于故障树方法在复杂系统的故障诊断应用中存在较大的局限性,其很难解决复杂系统在故障诊断中表现出的事件的多态性、信息的不确定性、故障逻辑关系的不确定性等问题,本文提出了一种新型的贝叶网络方法可以较好的解决这些问题。文中以酸洗线的风机系统的故障诊断为例,验证了这种新型方法的有效性。

| Abstract: | Due to the fault tree method had large limitations in the application of complex fault diagnosis system, which was difficult to solve complex system fault diagnosis polymorphism exhibited events, uncertainty of information, failure logical relationship and other issues, this paper presented a novel Bayesian network method, which could better solve these problems. Pickling line of the fan fault diagnosis system was taken as an example to verify the effectiveness of this new approach. |
