基于OMAP5912的电力载波视频监控系统设计

Design of Video Monitoring System Based on OMAP5912 and Power Line Communication

针对目前常用的视频监控系统传播方式的缺陷以及电力网络广泛分布的特点,采用PLC(powerline communication)技术和嵌入式多媒体技术,提出了一种新型的视频传输模式,该方案采用OMAP5912为主控芯片、Montavista Linux为操作系统、PLC模块为传输介质来实现视频数据的传输。介绍了硬件系统的设计和软件平台的搭建,并重点阐述了USB摄像头驱动设计、ARM和DSP的双核通信、PLC模块的数据传输。该系统为安防监控提出了一种新式便捷的解决方案。

Aiming at the defects of the video transfer and widely distribution of the power line network,a new video transfer mode was proposed based on the PLC module and the technology of embedded multimedia.The design takes the OMAP5912 as the central controller,Montavista Linux as the operating system and the PLC transfer module as the transmission media.The hardware and the software platform design were briefly described.And the system design was focused on the design of the USB camera driver,the communication between the ARM and the DSP,and the data communicate in PLC module.This system provides a new solution for the security monitoring.
