Design of FPGA-based network monitoring system for multi-channel video

针对市场对小型化、嵌入式、大场景视频监控的需求,设计一种基于FPGA的多路视频网络监控系统。该系统主要由摄像头采集模块、数据处理模块、缓存模块和以太网传输模块组成,通过TW2867芯片同时采集4路视频送入FPGA进行通道分离和视频格式转换,再利用DDR2高速存储多路视频数据,最后通过编程控制以太网收发器传输控制器RTL8211EG实现了视频数据的网络传输。视频监控终端可以通过网络接收视频流并进行实时显示,结果表明,该系统具有集成度高、体积小、实时性强、传输速度快等优点。

In allusion to the market demand for miniaturization,embedment and large scene video monitoring,a FPGA based network monitoring system for multi channel video is designed.The system is mainly composed of camera gathering mod ule,data processing module,cache module and Ethernet transmission module.Four channel video are simultaneously collected by the TW2867 chip and sent to FPGA for channel separation and video format conversion,and then the multi channel video da ta are stored by DDR2 at high speed.The Ethernet transceiver transmission controller RTL8211EG is controlled by programming to realize video data network transmission.The video monitoring terminal can receive the video streaming by the network and dis play it in real time.The system has the advantages of high integration,small volume,strong real time property and fast transmis sion speed.
