摘要
针对电子设备故障诊断的难点,通过分析贝叶斯网络的特点,设计了一种基于贝叶斯网络的故障诊断系统。首先介绍了故障及故障诊断的相关概念;然后在理解贝叶斯网络的基础上分析其优点,研究了贝叶斯的推理;进而研究贝叶斯故障诊断的关键技术;最后介绍了基于贝叶斯网络故障诊断系统的整体框架。
According to the fault diagnosis difficulties of electronic equipment,a Bayesian network-based fault diagnosis system is designed by analyzing the characteristics of Bayesian networks.First,the concepts of fault and fault diagnosis are introduced.Then,the advantages of Bayesian networks are analyzed based on understanding the networks.The reasoning process of Bayesian is studied.Key technologies of Bayesian fault diagnosis are studied.Finally,the whole framework of fault diagnosis system based on Bayesian network is discussed.
