摘要
无人机遥感载荷在无人机飞行过程中会产生大量载荷数据,这些数据需要实时存储并在返回地面后回放和分析;无人机遥感载荷数据存储系统是基于SOPC的数据存储解决方案;该方案使用多个固态硬盘作为存储介质并实现并行读写,使用SDRAM作为数据缓存,设计了超大块文件系统对数据进行管理;系统测试表明所设计的存储系统实现了1.8Gbps四路载荷数据的实时存储,满足无人机遥感载荷数据存储的要求。
A large quantity of data is generated by remote sensing payload of unmanned aerial vehicles（UAV）.The Data needs to be stored immediately and analyzed after returning to the ground.The system is a data storage solution based on SOPC.It concurrently accesses data on multiple solid state disks,uses SDRAM as data cache and manages data by proposed huge block file system.1.8Gbps four-way real-time data storage system is realized.Test results show that it meets the requirements of UAVs＇ remote sensing payload data storage.
