| Abstract: | This paper suggests that the method of intelligent fault diagnosis based on Bayesian Networks has huge advantages in solving the uncertainty and associated problems for device fault diagnosis. The mathematical basis of Bayesian Networks is depicted, and the idea and optimized algorithm of fault diagnosis based on Bayesian Networks are set forth. At last, an application example in the fault diagnosis of SINS/GPS integrated navigation system is given which shows that this method is effective. |
