锅炉故障检测与诊断技术研究

提出了一种基于深浅两层知识的锅炉故障检测与诊断方法。深知识包括锅炉系统的结构知识、物理模型和故障模型；浅知识就是经验知识，它是专家在长期的生产实践中总结出来的故障诊断经验。根据锅炉的结构和功能，对其系统进行分级描述，逐级划分直至部件或零件。系统的分级，大大减少了求解空间，提高了诊断的实时性。

Fault Detection and Diagnostics Techniques for Boiler

Based on deep and shallow knowledge used for boiler-fault-hunbing,its method is put forward in the paper. The deep knowledge includes the structure knowledge, physical models and fault models. The shallow knowledge is the experience knowledge of experts, which are summed up in practice. The boiler systems are described in hierarchies based on its structure and function so as to reduce the searching branches and improve the diagnosis real-time.
