Application and technology of fault diagnosis for information fusion

The various kinds,levels and basic features of information fusion and the formation as well as the key technology of the fusion system is introduced.Its ability to deal with the multi-sourse information is analyzed.Combining the data-mixing technology with fault-diagnosing theory,realizing the diagnosis of the transformer's failure based on the data-mixing skills by the levels information fusion of data,features and strategies,the influences of the transformer's uncertain error is reduced.Solving the uncertain reasoning process of the diagnosis for transformer's failure,and the precision of the diagnosis for transformer's failure is increased greatly.
