ARINC661座舱显示系统离线检测技术研究

On ARINC661 Cockpit Display System Offline Detection Technology

针对ARINC661规范下UA与CDS之间数据交互量大、传输周期短,实时监控过程中难以全面、细致地分析指令的问题,研究了座舱显示系统离线检测技术,设计了环形数据批量存储、仿真UA、异常定位等方法,可以在离线环境下重现指令交互过程。测试结果表明,该设计合理、运行可靠,可以在离线环境下检测交互指令。

In the ARINC661 specification,there is a large amount of data interaction between UA and CDS with short transmission period,and it is difficult to comprehensively and meticulously analyze the instructions in real-time monitoring process.To solve the problems,we studied the offline detection technology of the cockpit display system,and designed such methods as ring data batch storage,simulation UA,and anomaly positioning,which can reproduce the instruction interaction process in an offline environment.The test results showed that the design is reasonable,reliable,and can detect interactive commands in an offline environment.
