ARINC661座舱显示总线数据过滤技术研究

摘要

为实现对ARINC661飞机座舱显示系统中用户应用(UA)与座舱显示系统(CDS)间通信指令的监测与分析,对指令过滤技术展开研究.通过对通信过程中的交互指令进行分析,采用二叉树的结构,研究了高效过滤算法,实现了数据的高效过滤功能.地面试验表明,所提过滤方法正确,开发的指令监测显示软件运行可靠、性能良好,对座舱显示系统的开发起到了很好的辅助作用.%In order to realize the monitoring and analysis of communication instructions between User Application(UA) and Cockpit Display System(CDS) in ARINC661 cockpit display system,we studied the instruction filtering technology.An analysis was made to interactive instructions in the communication process,and the structure of the binary tree was used to obtain a filtering algorithm,which is efficient for data filtering.Ground tests showed that the filtering method is correct,and the designed instruction monitoring and display software is reliable and has good performance,which plays a very important role in the development of cockpit display system.
