摘　　要：基于一种潜标信号采集系统硬件平台,给出了FAT32文件存储的软件设计流程.该流程可实现基于物理接口层的磁盘根目录文件存储.提出了预成FAT表的软件设计方法,使得当CPU对磁盘访问速度较慢时,也可在不影响数据写入的情况下,利用微小时隙完成文件目录索引信息的建立.该设计已应用于实际工程中,海试结果证明其稳定可靠.Based on hardware platform of submerged buoy signal sampling system, FAT32 file storage software design process is given which can be used in file storage in root index of disk based on physical layer interface. Preforming FAT method in software design is proposed. With this method, files catalogue can be established in tiny moment without interfering with the data inputting when CPU can access the disk only at a low speed. The work has been used practically in project and the sea trial result has proven its reliability.
