Design of Aircraft Condition Monitoring Module based on AFDX Bus

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。

Abstract:

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 management 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.
