摘要
通过数据流的分析，能准确地检测系统性能、诊断系统故障。但在分析过程中，更多进行的是单一数据分析，而疏忽了数据流的关联性，这样导致漏诊、误诊时有发生。对于非关联性参数，通过单一数据流的直接分析，大都可以判断故障的原因和故障点。但关联性参数必须同时读取多个数据流，并通过相互关系进行计算确定关联性参数，然后进行综合分析，才能判断故障点和故障原因。
According to the data flow analysis, the system performance and fault system are able to tested and diagnosed accurately, but in the process of analysis, more focus on the single data analysis ignoring the correlation of data flow, which often leads to misdiagnosis. For the non - correlation parameter, the cause of failure and the trouble spots are directly detected by analyzing the single data flow, while the correlation parameters have to read multiple data flows simultaneously, and the related parameters could be determined by calculation of correlations to judge the cause of failure and the trouble spots after a comprehensive analysis.
