摘要
针对空调系统故障诊断的特点,在故障树分析法的基础上,应用面向对象技术,将四种单一的知识表示方法储存成一种混合的知识表示形式——基于规则、模型、过程和框架集成的广义故障树诊断知识表示方法(GFTDKRM),并且以集中式空调系统为对象给出了广义故障树诊断对象描述实例.从应用实例来看,广义故障树知识表示方法具有简洁、灵活、透明,且易于诊断推理的特点.
In view of the specific property of air-conditioning system fault diagnosis, generalized fault tree diagnosis knowledge representation method (GFTDKPM) is proposed and approached by applying object-oriented methodology. This new method is based upon the fault tree analysis, and integrates four common knowledge representation methods, namely rule, model, procedure and frame. The application example of air-conditioning system fault diagnosis is given, which proves that this knowledge representation method has characteristics of terseness, agility, transparency, and being easy to diagnose and infer.
