【摘要】 目前,嵌入式视频监视系统已成为国内外视频监视系统应用的主流,但是在IPv4平台下存在地址不足、不能合理分配带宽、安全性能及移动性能差等诸多问题,而新一代IPv6协议不仅能很好地解决以上问题,而且还具有可以提高视频传输速度和传输质量等多方面的优点。如何使嵌入式监视系统与IPv6技术相结合已经成为当前监视系统研究的一个重要方向。本文分析了IPv6嵌入式视频监视系统的研究现状及应用前景,深入研究了嵌入式系统软硬件技术、视频压缩技术和网络传输技术等关键技术,在掌握嵌入式系统开发及IPv6协议下的视频传输原理的基础上,设计了S3C2410+GO7007SB结构的嵌入式视频监视系统方案,并实现了在IPv6环境下嵌入式视频监视系统的基本功能。本文运用Protel DXP实现了系统硬件设计并对各主要功能模块进行了详细阐述,然后在Linux操作系统下实现了系统软件设计,包括视频采集与压缩模块的驱动程序及视频数据的RTP实时传输和IPv6视频组播,最后对系统进行了调试和测试。本文实现了嵌入式视频监视系统与IPv6技术的结合,是嵌入式系统的一个典型应用,具有一定的创新性和先进性。
【Abstract】 At present, the embedded video surveillance system (EVSS) has become main-stream system that the video surveillance system (VSS) is applied at domestic and international. But in IPv4 platform, it has many problems, such as addresses are shortage, bandwidth can’t be allcocated reansonably, safe function and move function are poor. On the other hand, the new generation protocol IPv6 which can not only be solved the above problems, but also increased the speed and quality of video transmission, and it also has other advangtages. How to make the EVSS and IPv6 techniques combined together has become an important researching direction on VSS at present.In the paper, the recent research situation and application prospect of IPv6 EVSS are analyzed and the key technologies such as embedded system soft & hardware, video compression and network transmission are deeply studied. An EVSS program of S3C2410+GO7007SB is designed based on mastering the principle of embedded system development and video transmission with IPv6. And the design implements the basic function of EVSS.The hardware design of system, whose main function modules are mainly described, is implemented by Protel DXP. Then the soft design of system including the driver of video capture and compression modules and the transmission and multicast of video is realized in Linux. Finally, the paper debugs and tests the design.The paper realized combination of IPv6 and EVSS that is a typical application of embedded technique and innovative and advanced.
