摘要
提出了基于BAS的空调系统过程监测与故障诊断模式 ,阐述用主成分分析法进行故障诊断的过程 ,并用其进行空调系统的传感器故障诊断。结果表明 ,主成分分析法具有很好的故障检测、故障识别和故障重构能力 ,还表明 ,故障诊断与BAS相结合是可行的。
Proposes the scheme of process monitoring and fault diagnosis of HVAC system based on building automation system.Principal component analysis (PCA) is presented and used to diagnose sensor faults in HVAC systems.The result shows that PCA has good ability of fault detection,fault identification and fault reconstruction.It also demonstrates the feasibility to combine fault detection and diagnosis(FDD) with BAS.
