基于uClinux的移动视频监控终端的研究与设计
摘要：在后PC时代，嵌入式系统的发展就成了计算机技术发展的1个热点，其中ARM7TDMI是1种RISC处理器，因为高效、低功耗、低成本，在嵌入式系统中应用最为广泛。由于社会发展的需要，数字视频监控系统的'应用也越来越广泛，其核心就是嵌入式系统，而采用CDMA1x的嵌入式视频监控终端专门针对移动环境或布线成本高的场所设计，较好地解决了这种情况下的视频监控问题。本论文研究了基于uclinux的移动嵌入式视频监控终端设计，以S3C44B0X为核心，以uclinux作为嵌入式操作系统，将前端采集的音、视频信号通过MPG440芯片压缩为MPEG-4视频数据，通过CDMA1x网络建立起监控终端和监控中心之间的连接，将视频信号传输到监控中心进行处理、存储，用户可通过手机或PC机浏览器登录监控中心网站，查看监控信号，进行实时监控，在移动环境或不易布线情况下也能较好地的实现视频监控，具有1定的实用性。

Research and Design of Mobile Video Surveillance Terminal Based on UClinux
Abstract: The development of embedded systems has been becoming a hotspot of computer technology. As a RISC processor, ARM7TDMI has been abroad applied in embedded systems with the characteristics of high efficiency, low power consumption and low cost. To meeting the demand of security in some important place, the digital video monitoring system has been growing rapidly in recent years, with its cores is embedded systems. The embedded system based on CDMA1X is designed for the applications of mobile environment and the places that is not easy to distribute cable.This paper reseaches the design of the mobile video monitor terminal based on uclinux, with the core is S3C44B0, and the OS is uclinux. The sound and video signal gathered from terminal is compressed to MPEG-4 video data via MPG440 chip. The MPEG-4 video data transferred from the terminal via CDMA1x can be processing and saving in monitor center. After logining the monitor center, useres can monitor the places with mobile phone and PC. This system implements real time monitoring in mobile environment and the places that is not easy to distribute cable, and has practicability on some contents.
