【摘要】：应用于航空的记录系统,要求具有比地面系统更高的可维护性和可靠性,体积和功耗也有严格的限制。针对这些要求,本文提出了基于ATR加固结构的嵌入式NAND Flash图像记录系统。系统采用CPCIE 3U规范设计,置于1/2 ATR机箱内,增强了系统的可靠性和可维护性。通过引入SRIO高速总线和NAND Flash存储阵列,解决了数据的高速实时记录。在此基础上,详细阐述了系统各板卡的设计。实验结果表明,该记录系统运行稳定可靠,记录速度达到912 MB/s,满足高分辨率航空CCD相机的记录要求。
[Abstract]:Aircraft recording systems are required to be more maintainable and reliable than ground systems, with strict limits on volume and power consumption. To meet these requirements, an embedded NAND Flash image recording system based on ATR reinforced structure is proposed in this paper. The system is designed according to CPCIE 3U specification and placed in 1 / 2 ATR chassis, which enhances the reliability and maintainability of the system. By introducing SRIO high speed bus and NAND Flash storage array, the high-speed real-time data recording is solved. On this basis, the design of each board card of the system is described in detail. The experimental results show that the recording system is stable and reliable, and the recording speed reaches 912MB / s, which meets the requirements of high-resolution aerial CCD camera.
