GPRS在嵌入式智能視覺監(jiān)控系統(tǒng)中的應(yīng)用

在智能視覺監(jiān)控系統(tǒng)中,當(dāng)分布式監(jiān)控點(diǎn)線路鋪設(shè)存在困難時(shí)，將GPRS應(yīng)用到系統(tǒng)中，
完善了系統(tǒng)功能，提高了系統(tǒng)的靈活性和可擴(kuò)充性。本文首先介紹了無(wú)線視覺監(jiān)控系統(tǒng)的網(wǎng)絡(luò)結(jié)構(gòu)，再介紹了基于ADSP BF533的嵌入式智能視覺監(jiān)控系統(tǒng)的硬件平臺(tái)設(shè)計(jì)，最后重點(diǎn)討論了圖像傳輸?shù)能浖O(shè)計(jì)。經(jīng)實(shí)驗(yàn)證明，本系統(tǒng)每秒可傳送2-4幀圖像，基本滿足對(duì)實(shí)時(shí)性要求不高的應(yīng)用場(chǎng)合。

Abstract：In intelligent vision surveillance system , there is trouble when we lay circuitry of
surveillance spot ,so we bring forward that apply GPRS to this system ,that could consummate the system's function., improve the system's flexibility and expandability .Firstly this paper
introduction network architecture of the whole system, secondly introduction that the design of hardware platform of the Embedded Intelligent Vision Surveillance System based on ADSP
BF533. Finally focused on design of the image transmission software . The experiment proved
that the system can transmit 2 -4 frame images per second, Basically meet applications for the
demand of real-time is not high .
