一种视频监控实验系统简易且低成本制作方案

Simple and low-cost manufacturing scheme for video monitoring experimental system

选取视频监控系统,抽象其原理框架并进行必要的简化和技术替代:用文件传输代替传统视频监控的流传输,回避了复杂的SIP会话管理和复杂的RTP/RTSP流传输协议;采用极低成本的Xilinx Zynq 7020构建存储服务器,其中内嵌2个高端ARM处理器分别用作文件服务器和存储服务器,省略了传统视频监控系统的注册/代理服务器和流媒体中间件;采用Marvell的SATA端口复用芯片构建大容量磁盘阵列,实现存储服务器扩容量,形成一款适用于学生制作的极低成本、大存储容量的简易视频监控系统,也适用于对成本控制严格的智能社区或家居的应用场合。

The video monitoring system is selected to abstract its principle framework,and make the necessary simplification and technical substitution. The file transmission is used to replace the streaming transmission of the traditional video monitoring so as to avoid the complex SIP session management and the complex RTP/RTSP streaming transmission protocols. A very low cost Xilinx Zynq 7020 is adopted to build storage servers. Two high-end ARM processors are embedded and act as the file server and the storage server,omitting the registration/proxy server of the traditional video monitoring system and the streaming media middleware. The SATA port multiplexing chip of Marvell is used to build a large capacity disk array to realize the expansion capacity of the storage server. A simple video monitoring system with very low cost and large storage capacity is built,which is easy for the students to make,and is also suitable for the intelligent community or household applications with the strict cost control.
