摘　　要：为实现声纳数据的海量实时存储,提出一种基于COM Express架构的数据记录仪的设计与实现方法。该记录仪在COM Express载板上集成了ETXexpress处理器模块、光纤数据采集子卡,以及由4个500 GB硬盘组成的RAID0存储阵列。应用结果表明,该记录仪可以达到80 MB/s以上的实时存储速率,很好地胜任了声纳数据的存储任务。In order to implement the real-time mass data storage in the SONAR system, a method of data recorder＇s design and implementation which based on COM Express architecture is proposed. The recorder integrated ETXexpress CPU module, fabric data acquisition board and RAID0 storage array that composed by four 500 GB hard-disks on a COM Express carrier board. The results of application indicated that, the real-time storage velocity of the recorder can be above 80 MB/s, and it can be competent for task of SONAR data storage.
