基于uClinux的移動(dòng)視頻監(jiān)控終端的研究與設(shè)計(jì)
摘要:在后PC時(shí)代,嵌入式系統(tǒng)的發(fā)展就成了計(jì)算機(jī)技術(shù)發(fā)展的1個(gè)熱點(diǎn),其中ARM7TDMI是1種RISC處理器,因?yàn)楦咝、低功耗、低成本,在嵌入式系統(tǒng)中應(yīng)用最為廣泛。由于社會(huì)發(fā)展的需要,數(shù)字視頻監(jiān)控系統(tǒng)的應(yīng)用也越來(lái)越廣泛,其核心就是嵌入式系統(tǒng),而采用CDMA1x的嵌入式視頻監(jiān)控終端專(zhuān)門(mén)針對(duì)移動(dòng)環(huán)境或布線成本高的場(chǎng)所設(shè)計(jì),較好地解決了這種情況下的視頻監(jiān)控問(wèn)題。本論文研究了基于uclinux的移動(dòng)嵌入式視頻監(jiān)控終端設(shè)計(jì),以S3C44B0X為核心,以u(píng)clinux作為嵌入式操作系統(tǒng),將前端采集的音、視頻信號(hào)通過(guò)MPG440芯片壓縮為MPEG-4視頻數(shù)據(jù),通過(guò)CDMA1x網(wǎng)絡(luò)建立起監(jiān)控終端和監(jiān)控中心之間的連接,將視頻信號(hào)傳輸?shù)奖O(jiān)控中心進(jìn)行處理、存儲(chǔ),用戶可通過(guò)手機(jī)或PC機(jī)瀏覽器登錄監(jiān)控中心網(wǎng)站,查看監(jiān)控信號(hào),進(jìn)行實(shí)時(shí)監(jiān)控,在移動(dòng)環(huán)境或不易布線情況下也能較好地的實(shí)現(xiàn)視頻監(jiān)控,具有1定的實(shí)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.
