基于故障树分析法的建筑设备可靠性分析

Reliability Analysis of Building Equipment Based on FTA

通过对可能造成建筑设备故障的各种因素(包括硬件、软件、环境、人为因素等)进行分析,建立了故障树模型,从而确定系统故障原因的各种可能组合方式及其发生概率,提高了系统可靠性,拓展了故障树分析法的使用领域。该方法在建筑物设计阶段,可以帮助设计人员找出关键单元,对设计提供一定的参考意见。在使用维修阶段,可以帮助人们进行故障诊断和降低出错的可能性。

Through the analysis on every kind of factors （ such as hardware, software, environment, human factor,et al） which could make the building equipment fault, the fault tree model was established. The reasons of system fault in every possible combination way and its probability could be confirmed by the fault tree model. Therefore, the system reliability was improved and the application domain of FTA was extended. It could help designer to discover the key unit and provide some opinions in the building design stage. Otherwise, it may help people to carry out the fault diagnosis and deduce the possible fault in the using service stage.
