摘要：

随着嵌入式数据采集系统的不断发展，将数据以某种常用文件系统的形式保存在外存中的方法得到了越来越广泛的使用。针对嵌入式存储系统自身的特点以及采用缓存机制而带来的问题，采取某种应对系统故障的恢复机制显得十分必要。该文基于嵌入式数据存储系统的特点提出了一种数据恢复机制，对该机制进行了分析并予以实现。

Abstract:

As embedded data acquisition system is evolved continuously, data is stored in storage in term of a usual file system´s format more and more. Aimed at the characteristics of embedded system itself and the problem with cache mechanism, it is very necessary for data storage system to adopt some kinds of recovery mechanism to settle system fault. This paper presents a kind of recovery mechanism based on specialities of embedded data acquisition system, and analyzes and realizes it.
