【摘要】 针对放射源监控的实时性和网络多媒体远程访问的新要求,提出一种基于嵌入式ARM-Linux有线和无线传输的B/S模式Web远程放射源实时视频监控系统。系统采用ARM920T内核的微控制器S3C2440版和UVC格式/YUV编码标准USB摄像头构建Web服务器端,详细设计嵌入式Linux下摄像头的驱动程序,分析视频数据采集与传输的开源MJPG-Streamer视频服务软件,结合Vedio4Linux2接口和socket网络编程,并将其移植到嵌入式Web服务器端。监控系统的测试表明:经过压缩与编码处理后其图像数据流信息能稳定、可靠的显示在监控终端的浏览器中,在放射源和核设备实时监控中取得优良的效果。更多还原

【Abstract】 For the new requirements for radioactive sources monitoring such as real-time,networked multimedia remote access etc., the radioactive sources real-time video monitoring system of B/S model with remote web access is presented,which is based on wired and wireless transmission of the embedded ARM-Linux. It uses the S3C2440 controller board with ARM920 T core and USB camera of UVC format and YUV coding to build web server, the camera driver on embedded Linux is designed in detail,the video data acquisition and the open source MJPG-Streamer video service software are analyzed,and the port of Video4Linux2 and the network programming of socket are combined and ported into the embedded web server. The monitoring system test results show that the image data flow information can display stably and reliably on the monitoring terminal browser after compressing and encoding process, and achieve excellent results on the real time monitoring of the radioactive sources and the nuclear equipments.更多还原
