| Abstract: | IN this paper , the model-blocked of device structure and model-layered of faults diagnosed device are discussed . A new intelligent diagnostic model which combines artificial neural networks (ANN ) with expert system ( ES ) is developed . Its knowledge base , knowledge representation , and knowledge acquisition are emphatically studied , and the diagnosing process is described . The tests are carried out in the laboratory on MK9-5 cigarette machine . The experimental results show that the new in- telligent diagnostic approach has higher effectiveness and liability than the common diagnostic expert sys- tem . It is expected to be further developed and improved to be applied in practice . |
