基于Windows CE的嵌入式開(kāi)發(fā)研究
Research of Embedded Development Based on Windows CE
【摘要】 近年來(lái)基于嵌入式系統(tǒng)的數(shù)字化產(chǎn)品在全球范圍內(nèi)得到了突飛猛進(jìn)的發(fā)展,嵌入式技術(shù)已成為一個(gè)研究熱點(diǎn)和消費(fèi)熱點(diǎn)。而Windows CE由于它的多任務(wù)、實(shí)時(shí)性、模塊化、強(qiáng)大的通信能力等特點(diǎn),在嵌入式系統(tǒng)的諸多領(lǐng)域都有了廣泛的應(yīng)用。本文首先探討了嵌入式系統(tǒng)的特點(diǎn),分類,前景,然后對(duì)各種嵌入式操作系統(tǒng)和Windows CE的特點(diǎn)及開(kāi)發(fā)工具進(jìn)行分析比較,接著介紹一個(gè)我們?cè)贛icrosoft Windows CE 5.0環(huán)境下基于eBoxII開(kāi)發(fā)的智能家居安防保全系統(tǒng)eDog。eDog 可以通過(guò)攝像頭將采集到的實(shí)時(shí)視頻圖像進(jìn)行運(yùn)動(dòng)檢測(cè),當(dāng)發(fā)現(xiàn)有運(yùn)動(dòng)產(chǎn)生時(shí),通過(guò)撥打電話等多種方式自動(dòng)向用戶發(fā)出警報(bào),同時(shí)將實(shí)時(shí)捕獲的圖像上傳到ftp 服務(wù)器。文章的最后詳細(xì)闡述了eDog的圖像采集模塊,運(yùn)動(dòng)圖像檢測(cè)模塊,圖像壓縮模塊,F(xiàn)TP上傳模塊的實(shí)現(xiàn)過(guò)程,并對(duì)我們所提出的運(yùn)動(dòng)檢測(cè)算法,視頻捕捉算法等做了詳細(xì)的說(shuō)明。
Abstract:
By using gateway systems on large 32-bit platforms, networks of small, 8- and 16-bit
microcontrollers can be monitored and controlled over the Internet. With embedded Linux, these
gateways are easily moved from full-blown host PCs to embedded platforms like the PC104. In
this class you will learn about hardware platforms that support embedded Linux, Linux kernel
configuration, feature selection, installation, booting and tuning.
This is a collection of m-files I created to complete a research project into the DC components of various encoding techniques. Eight of the files create random bit sequences that conform to their coding requirements. The others were files I found useful in the scope of the project and supplement the generating m-files.
