Abstract


In this paper, based on national defense scientific research \and other characteristics , the introduction of hidden Markov models and artificial immune system as a basic modeling and identification tools, integrated the advantages of both , for nuclear power equipment condition monitoring and fault diagnosis , application Visual C development of the corresponding nuclear power equipment fault diagnosis system . Late in the development of a large number of experiments verify the effectiveness of the system , robustness and forecasting in real time. The main contents are as follows : The first chapter introduces the research background and nuclear equipment fault diagnosis significance of nuclear power equipment fault diagnosis technology research status summary paper introduces the characteristics and innovation ; Finally, the main contents of this paper , and gives the overall framework of the paper . The second chapter the basic theory of HMM and AIS made ??a presentation highlighting HMM and AIS several basic algorithms. Studied the HMM and AIS equipment fault diagnosis in nuclear power applications , and presents an improved AIS algorithms. The third chapter describes the AIS HMM-based and nuclear power equipment fault diagnosis system architecture , based on the application of Visual C developed a hybrid model based on HMM with AIS nuclear power equipment fault diagnosis system, and the system software structure and function modules , and software design of some key technologies are described. Chapter IV developed through experiments based on HMM with the AIS nuclear power equipment fault diagnosis system was validated describes a device used in the experiments and instruments , given the specific experimental protocols and some typical experimental results and the experimental the results were analyzed. Chapter V summarizes the full text of research results, and future work are discussed. This study for the promotion of nuclear power equipment condition monitoring and fault diagnosis technology, to guarantee the safe and reliable operation of nuclear power facilities , improve defense fighting has important theoretical significance and practical value.
