电能量采集终端的数据存储策略

电能量数据终端的数据类型随着应用水平的提高不断扩展，对数据存储提出了更高的要求。文中结合NOR型Flash存储器件给出一种分类型区别存储的设计策略，特别针对不断扩充的不定结构数据类型讨论了一种虚拟小区块文件系统的应用，并相应弥补原有的效率缺陷。

DATA STORAGE STRATEGIES IN AN ENERGY REMOTE TERMINAL UNIT

With the improvement of the application level, the data type of the energy remote terminal unit (ERTU) is steadily expanding with higher requirements made on data storage. According to an NOR-based Flash memory, a classified discriminating storage strategy based on the type and medium of the data is proposed. In particular, a kind of virtual small block file manager (VFM) is applied to store the data of a steadily expanding and uncertain structure while making up the efficiency limitation in the original design.
