摘　　要：在航空产品的航电系统跨代升级中,FC总线数据的检测分析是飞行试验对航空产品航电系统进行鉴定的一项重要内容。针对复杂航空环境下采集记录的FC总线数据的多类、随机性等特点,提出了对FC数据进行关键数据元素的消息识别方法,以及FC总线数据帧的网络特性检测方法,并结合FC总线周期丢包检测算法,设计了FC总线的检测分析技术,实现了对复杂测试记录的FC总线数据的检测分析;最后在某试验机的飞行试验中进行了应用,获得了飞行试验FC总线检测分析结果,试验表明检测分析的结果数据满足飞行试验对航电系统进行科研鉴定的需求。In the cross-generation upgrade for the avionics system of the aviation equipments,the detection and analysis of FC bus data are the important contents in the flight test to identify the avionics system of the aviation equipments. For the collected and recorded FC bus data in complex aviation environment has the characteristics of multiclass and randomness,the method to conduct the message identification of the key data elements for FC data,and the method to detect the network characteristics of the FC bus data frame are put forward. The packet loss detection algorithm of FC bus cycle is adopted to design the detection and analysis technology of FC bus data. The detection and analysis of FC bus data recorded in testing in complex environment were realized. The technology was applied to the flight test of a testing aircraft,and the detection and analysis results of the FC bus were obtained in flight test. The test results show that the detection and analysis results can satisfy the scientific research and appraisal demands of flight test to avionics system.
