摘　　要：为了实现飞机状态监控模块对机载高速AFDX总线网络海量数据的监控需求,分析机载网络构型,并从数据帧处理、文件管理和用户接口等几个方面对状态监控模块进行设计,通过中断和分级任务的相互配合,提出了两级筛选、三级缓冲的机制;使用专用地面数据分析工具对监控数据进行分析,结果表明此状态监控模块能够确保监控数据的实时捕获、处理和存储;经过验证,使用两级筛选、三级缓冲的机制设计的状态监控模块,可针对不同的任务配置不同的监控需求,能够实现飞机状态监控功能,符合设计要求,运行稳定。In order to achieve the aircraft condition monitoring module monitoring demand of airborne high--speed AFDX bus network huge amounts of data, analyzed the network configurations, and designed condition monitoring module as data frame processing, file manage- ment and user interface, by used the interrupt and classification tasks together, put forward the two--level filter, three--level buffer mechanism. Use the dedicated ground analysis tool analyzes the data, the results show that the condition monitoring module can ensure real--time capture, processing and storage of the monitoring data. The condition monitoring module designed of two--level filter, three--level buffer mechanism prove to configured with different monitoring requirements for different tasks, realize the aircraft condition monitoring functions, and meets the design requirements, running stability.
