基于达芬奇技术的矿用视频监控系统设计

摘要

针对传统的矿用视频监控系统采用DSP+ ARM方案存在稳定性差、成本高的问题,提出了一种基于达芬奇技术的矿用视频监控系统的设计方案.该系统以基于双核芯片DM6446的达芬奇平台为核心,其中的DSP核采用MPEG4算法压缩编码由模拟摄像头采集的视频信息,编码后的视频数据经达芬奇平台内部通道传输到ARM核,ARM核将编码后的视频数据通过UDP网络传输到服务器端,服务器端接收视频数据后进行解码播放,从而实现在达芬奇平台下的视频监控功能.实验结果表明,该系统具有较高的稳定性,但要应用于煤矿还需要进行大量的现场试验.%In view of problems of bad stability and high cost in traditional mine-used video monitoring system by use of DSP+ARM scheme, the paper proposed a design scheme of mine-used video monitoring system based on Da Vinci technology. The system takes Da Vinci platform based on dual-core chip DM6446 as core. DSP core uses MPEG4 algorithm to compress and code video information collected by simulated camera, then the coded video data is transmitted to ARM core through internal channel of Da Vinci platform. ARM core sends the coded video data to server through UDP network and the server receives the data and makes decode and play, so as to realize video monitoring function under Da Vinci platform. The experiment result showed that the system has higher reliability, but it need make a lot of field tests for coal mine use.
