摘要:

对QAR 数据和ACARS 报文数据的同源性进行了分析,对发动机稳态报文的结构及其生成逻辑进行解析,提出了一种从QAR 数据中提取出满足触发条件的发动机稳态报文的研究思路和方法,利用该方法不仅可以充分挖掘QAR 数据中大量原始监控数据,还可获得按逻辑提取的模拟ACARS报文,借助该报文可为航空公司提供应急处置方案,协助其进行飞机和发动机的状态监控及故障诊断,也可以将其用于科研单位及高校的研究和教学,通过对B747-400飞机实际ACARS 报文数据和提取报文数据进行计算分析,验证了该方法的可靠性袁具有良好的应用前景。

关键词: QAR 数据, ACARS报文, 同源性分析, 提取逻辑, 可靠性检验

Abstract:

The homology of QAR data and ACARS report data has been analyzed, as well as the structure and extraction logic of the engine stable frame report. An extracting method of engine stable frame report which meet the triggering conditions from QAR data is proposed. With the help of this method, not only the vast amount of raw monitoring QAR data can be fully tapped, but also a simulated ACARS report is obtained, which can be used in emergency management of airlines, assisting researches in condition monitoring and fault diagnosis of aircraft and engine. It can also be used in universities and scientific research units in teaching and researching.Computational analysis of both the actual ACARS reports and the extracted data of a B747- 400 airplane verifies the reliability and great prospects in application of this method.

Key words: QAR data, ACARS report, homology analysis, extraction logic, reliability testing
