基于uClinux的移動視頻監(jiān)控終端的研究與設計
摘要:在后PC時代,嵌入式系統的發(fā)展就成了計算機技術發(fā)展的1個熱點,其中ARM7TDMI是1種RISC處理器,因為高效、低功耗、低成本,在嵌入式系統中應用最為廣泛。由于社會發(fā)展的需要,數字視頻監(jiān)控系統的'應用也越來越廣泛,其核心就是嵌入式系統,而采用CDMA1x的嵌入式視頻監(jiān)控終端專門針對移動環(huán)境或布線成本高的場所設計,較好地解決了這種情況下的視頻監(jiān)控問題。本論文研究了基于uclinux的移動嵌入式視頻監(jiān)控終端設計,以S3C44B0X為核心,以uclinux作為嵌入式操作系統,將前端采集的音、視頻信號通過MPG440芯片壓縮為MPEG-4視頻數據,通過CDMA1x網絡建立起監(jiān)控終端和監(jiān)控中心之間的連接,將視頻信號傳輸到監(jiān)控中心進行處理、存儲,用戶可通過手機或PC機瀏覽器登錄監(jiān)控中心網站,查看監(jiān)控信號,進行實時監(jiān)控,在移動環(huán)境或不易布線情況下也能較好地的實現視頻監(jiān)控,具有1定的實用性。

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.
