基于SOPC的家居安防视频监控系统的设计

Design for home security video monitoring system based on SOPC

提出了以NiosⅡ软核处理器为核心,利用SOPC技术构建网络硬件平台,采用TCP/IP协议栈实现信息数据网络化传输的家居安防视频监控系统的设计方案。详细分析了系统的功能需求,确定了系统总体设计方案;对系统主要功能模块的设计、配置进行了分析,给出了部分电路的具体实现方法;提出了利用uClinux开放的TCP/IP协议代码实现信息数据网络化传输的方法,分析了图像采集部分的软件设计,给出了相应的设计流程。采用SOPC方案进行系统设计,充分利用了FPGA的可编程性,整个开发过程变得灵活方便;以嵌入式操作系统uClinux作为软件平台,图像的采集和网络传输更为稳定可靠。

This paper provides a design plan for the video monitoring system certered on Nios Ⅱ soft,used SOPC technic to built the hardware development platform,adopted TCP/IP protocol to implement data transmission.The overall design of system was decided by analyzing the functional requirements.Configuration design and implementation of the subfuction circuits were illustrated by also analyzing the module design.The implementation of information data transmission method was presented by using the uClinux-open TCP/IP protocol.The software design of image acquisition module was analyzed and correspongding design plan was illustrated too.Adopting SOPC plan to design system can make fully use of the FPGA programmabirity and the whole development process becomes free and convenient,The acquisition of image and Internet transmission become more reliable by using uClinux as software platform.
