摘要:

为进一步降低飞机备份导航系统控显仪的重量、功耗与成本,改善其实时性,提出了一种基于ARM+OLED的设计方案,以满足备份导航系统的综合性能要求；采用安装VxWorks实时操作系统的S3C2440为核心处理器完成通讯数据处理与解算,通过FPGA实现数据缓存及逻辑控制功能,选用OLED作为显示设备、利用双缓存显示技术完成导航界面显示；实验测试表明设计可行,该控显仪能实时直观地显示各类导航信息,与市场同类产品相比,具备小型轻型低功耗的优点,符合航空领域的应用要求。 

Abstract:

To reduce the weight, power dissipation, cost further and improve real-time of display console in backup navigation system of aircraft, proposes a design based on ARM and OLED, which can fulfill the overall performance requirements of backup navigation system. It uses the S3C2440 installed VxWorks RTOS as the core processor to complete communication data processing and calculating, utilizes FPGA to complete data caching and logic control, selects OLED and adopts double-buffers mechanism to accomplish navigation interface display. Practice test show that the design is feasible. The systerm can display navigation information in real-time and intuitively. It meets the application requirements of aerospace equipments with small size, light weight and low power advantages compared to similar products on the market.
