摘要
针对建筑自动化系统(BAS)故障诊断日趋困难的问题,将专家系统与故障树分析法相结合,提出一种基于专家系统的BAS故障诊断方法。采用框架和规则相结合的知识表示法,建立相应的知识库。设计基于"框架规则+不确定性推理"的推理模式,给出专家诊断系统的实现方法。实验结果表明,该系统能提高推理结果的可用性。
Aiming at increasing difficulty in fault diagnosis of Building Automation System（BAS）,the theory of expert system and fault tree analysis are integrated to form a fault diagnosis expert system of BAS.An expression method integrating frame and rule is put forward,and the knowledge base is structured.A reasoning mode combining frame-rule with non-deterministic reasoning with high efficiency is designed to improve the usability of conclusion.Implementation of diagnosis expert system and results are presented to validate its feasibility.
