摘要
为实现对航电系统Ethernet总线数据进行地面在线测试,通过Ethernet总线通信方式,并采用嵌入式技术,对航电系统一系列飞行参数进行采集并处理,最终实现嵌入式航电系统Ethernet数据测试平台。硬件设计以ARM处理器为核心,设计数据处理模块、适配单元模块、电源管理模块和外设模块。软件设计在硬件平台的基础上,开发Android操作系统下的设备驱动及应用程序。工程应用结果表明:该平台能够实现对航电系统Ethernet总线检测和测试,满足测试需求。
To realize online ground test for Ethernet bus data of avionics sys tem, a se ries of flight data of avionics system is collected and processed with the Ethernet bus communication method and embedded technology and finally an Ethernet data test platform of embedded avionics system is realized. With regard to the hardware design, ARM microprocessor is taken as the core and data processing module, adaptive unit m o du le, power management module and peripheral module are designed. With regard to software design, device driver and application program under the Android operating system are developed based on the hardware platform. Results of engineering application show that the platform is able to check and test the Ethernet bus of avionics system and meet the testing requirement.
