激光捷联惯组大数据采集系统设计与实现

摘要

This paper uses a multi-core DSP as CPU and uses a mass memory Nand Flash to memory big-data of laser SINS on real-time.The system can store data while it's working,and data can be downloaded quickly by Ethernet later. The system is applied in one type of laser SINS successfully and works well.%以多核DSP芯片TMS320C6674为CPU,Nand Flash(以下简称Flash)为存储器,设计了激光捷联惯组大数据采集系统,可在设备工作时将导航数据实时保存,事后通过以太网进行高速下载,使激光捷联惯组大数据获取变得简单、可靠.该系统已在多个型号激光捷联惯组上成功应用,效果良好.
