摘要
针对智能设备数据记录系统中数据容量大和掉电不保护的问题,提出一种在μC/OS-Ⅱ操作系统和uC/FS文件系统下,利用基于国产32位处理器核CK510的MCU芯片而改造的具有日志结构的文件系统。该文件系统通过顺序记录数据以及将管理信息的改写和存储同时进行的方法,有效节省了SD卡的数据存储空间,提高了存储的稳定性。
Aiming at the problems of smart device data recording system in large data storage and no protection at power failures,a file system with log structure is proposed,which is recast using MCU chip of 32-bit home-made processor kernel CK510 under the operational system μC/OS-II and the file system uC/FS.This new file system effectively saves data storage space of SD card and improves the stability of storage by the method of consecutively recording data and concurrently rewriting and storing management information.
