在数据采集领域，一般是采用定点采集数据并传输至集中节点管理，这种方式会产生大量远程传输带宽，并且在多用户使用数据的过程会使得中心节点的负载过重。本文结合实际应用需求，通过对分布式文件系统 FastDFS 的原理进行分析，针对数据采集应用，改进 FastDFS 并设计了一种适合数据采集与使用的分布式存储系统。设计了组、小组、存储服务器的三级存储模式，增强了存储系统的拓展能力同时为数据采集上传带来方便，取得了较好的效果。

In the field of data acquisition. It’s the general way to collect fixed-point data and transmit them to a center node to manage. In this method it will produce a large number of remote transmission bandwidth. And the center manage node maybe overloaded when there are large numbers of users. Combined with the practical application demand, through the analysis of the principle of FastDFS, according to the data acquisition application, improved FastDFS and design a dis-tributed storage system that fit data acquisition very well. With the three lever storages that includes group, small group and storage storage server ,the development ability of the storage system is enhanced , and this achieved good results.
