【摘要】：随着信息技术的迅速发展，嵌入式技术开始出现在我们生活的各个角落，同时传统的视频存储技术已无法满足当前视频数据海量性、远端操作性、可管理性等多方面的需求，，网络化成为必然趋势，它将成为主要的信息承载和处理方式，这必然给网络化视频存储提出了要求、带来了挑战。本课题正是顺应嵌入式技术与网络化视频存储的发展潮流，研究并实现了基于网络的嵌入式视频存储系统。本系统采用NAS存储架构，硬件核心为基于ARM920T内核的AT91RM9200芯片，嵌入式Linux内核为Linux-2.4.27-vrsl-ATMEL。首先，本文介绍了视频存储、网络存储的概况及研究意义，对网络存储的几种主要架构进行了简介，提出了网络化视频存储系统总体设计，包括基于NAS的硬件及软件设计。接着，为实现系统开发，本文讲述了交叉编译环境的搭建、嵌入式Linux系统的移植等开发平台的搭建情况。随后，描述了网络化视频存储系统的三大模块，即采集、存储及检索模块，重点讲解了其中的存储模块，设计了对应的存储及检索策略，并最终实现了视频存储和检索功能。最后在Goahead Webserver的基础上实现了对NAS视频存储系统的远程管理。本文采用嵌入式技术和NAS附网存储技术相结合的方式实现了网络化视频存储系统，并较好的实现了视频的存储以及检索回放，推广了嵌入式技术和NAS技术的应用。
[Abstract]:With the rapid development of information technology, embedded technology began to appear in every corner of our life, at the same time, the traditional video storage technology has been unable to meet the current massive video data, remote operation, management and other aspects can demand, network has become an inevitable trend, it will become the main carrier of information and processing way, this bound to the network video storage requirements, challenges.
This subject is to comply with the development trend of embedded video storage technology and network, the research and implementation of embedded video storage system based on network. This system adopts NAS storage architecture, hardware core is AT91RM9200 chip based on ARM920T kernel, embedded Linux kernel for Linux-2.4.27-vrsl-ATMEL. first, this paper introduces the general situation and research significance of video storage, network storage the several main architecture of network storage are introduced, put forward the overall design of network video storage system, including the design of hardware and software based on NAS. Then, for the realization of system development, this paper describes the build of cross compile environment and build transplant development platform of embedded Linux system. Then, described three modules, network video storage system that is the collection, storage and retrieval module, the storage module focuses on the design The corresponding storage and retrieval strategy is implemented, and finally the function of video storage and retrieval is realized. Finally, remote management of NAS video storage system is implemented on the basis of Goahead Webserver.
This paper implements the networked video storage system by combining embedded technology and NAS attached storage technology, and achieves the video storage and retrieval playback. It extends the application of embedded technology and NAS technology.
