摘要：
This paper is based on the traditional network of bayesian, introducing the concept of the time window, to construct the Temporal Bayesian Network (TBN) model. In addition, optimizing TBN model reasoning algorithm to process system data which has the temporal haracteristic. Then we can obtain the posterior probability of each node in the TBN and use importance ranking method to determine the fault retrieval sequence, optimize of fault diagnosis process. Combined with the state power line fault diagnosis example to verify the correctness of this method.
