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。

Abstract: 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.

Key words: Building Automation System(BAS), expert system, fault diagnosis, knowledge express, non-deterministic reasoning
