基于专家系统的建筑智能化系统故障诊断

Fault Diagnosis of Building Intelligent System Based on Expert System

当前智能化系统(Intelligent System,IS)在建筑中的应用日趋广泛,其功能越来越强大,系统越来越复杂,发生故障后诊断和修复也日趋复杂。本文针对这一问题,提出了一种基于专家系统的故障诊断方法,对IS故障诊断专家系统的结构,知识表示,推理等方面进行了分析探讨,提出了框架和规则相结合的知识表示法,研究设计了基于"框架规则+不确定性推理"的推理模式,既方便实现,又利于推理效率的提高,为故障的快速定位和解决提供了先进的手段。

At present,the application of intelligent system （IS） to buildings turns extensive gradually. The system becomes more complicated and its function is stronger,but the diagnosis and repair turns more complex as well. To solve this problem,the paper proposes a diagnosis method based on expert system,and discusses the structure of the system,knowledge expression and reasoning. An expression method integrating rule and frame is put forward,and a reasoning mode combining frame-rule with non-deterministic reasoning with high efficiency and simple realization. The result of the paper provides an advanced means of finding and solving the fault in IS.
