According to the problem of information uncertainty during the process of fault diagnosis, a model of circuit fault diagnosis is proposed based on Bayesian inference. The definition of probability is extended in this model, which is explained as the subjective faith degree of experts. Besides, the knowledge process is added to the process of fault diagnosis, and the determinant rules of fault are given. Finally, the model is used in some circuit fault diagnosis, and qualitative analysis and quantitative calculation show that the model is effective and reasonable.
