Abstract: The technology of information fusion is used in the fault diagnosis for ship nuclear power plants in this paper.The space fusion structure is built based on fault tree expert system,NN diagnosis system,and mechanism model validation system.Not only the system deep-level knowledge,but also the shallow knowledge and the mechanism model knowledge are fully used.The simulation validation and verification showed that the information fusion diagnosis system could improve the fault diagnosis reliability effectively.
