1、論文題目:基于WinCE的網(wǎng)絡(luò)傳輸系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn)專業(yè):電路與系統(tǒng)碩士生:李舉名(簽名)指導(dǎo)教師:李文峰(簽名)摘要近年來,我國(guó)礦山事故頻發(fā),造成巨大經(jīng)濟(jì)損失和政治影響。為此,國(guó)家煤礦安全監(jiān)察局成立了礦山應(yīng)急救援指揮中心,完善應(yīng)急救援指揮平臺(tái)體系。礦山應(yīng)急救援通信系統(tǒng)是應(yīng)急救援指揮平臺(tái)的重要組成部分。當(dāng)井下發(fā)生事故時(shí),在井下原有通信系統(tǒng)癱瘓情況下,該系統(tǒng)為應(yīng)急救援指揮提供強(qiáng)有力的應(yīng)急通信服務(wù)。本課題來源于國(guó)家科技支撐計(jì)劃“基于Mesh網(wǎng)絡(luò)井下可視化無線救災(zāi)通訊技術(shù)與裝備(SQ2011SF13B00488)”。礦山
2、應(yīng)急救援通信系統(tǒng)的通信方式采用有線與無線、固定與移動(dòng)相結(jié)合的方式,本文主要完成有線和無線WiFi網(wǎng)絡(luò)傳輸系統(tǒng)設(shè)計(jì)工作。此網(wǎng)絡(luò)傳輸系統(tǒng)設(shè)計(jì)包括有線和無線WiFi模塊的驅(qū)動(dòng)設(shè)計(jì)與軟件設(shè)計(jì)兩部分,采用S3C6410微處理器和WinCE嵌入式操作系統(tǒng)為相應(yīng)的硬件和軟件開發(fā)平臺(tái)。有線和無線WiFi模塊分別選用DM9000以太網(wǎng)控制芯片和USI公司的WM-G-MR-09模塊進(jìn)行驅(qū)動(dòng)設(shè)計(jì)與移植。軟件設(shè)計(jì)部分針對(duì)S3C6410微處理器對(duì)Bootloader做了較為詳細(xì)的分析和移植。在深入研究TCP/IP協(xié)議之后,對(duì)TCP/IP
3、協(xié)議包源碼進(jìn)行代碼改進(jìn)與接口設(shè)計(jì),實(shí)現(xiàn)WinCE平臺(tái)下TCP/IP協(xié)議的成功移植。最后根據(jù)本文的設(shè)計(jì)目標(biāo),制定了相應(yīng)的自定義網(wǎng)絡(luò)通信協(xié)議,并在VisualStudio2005集成開發(fā)環(huán)境下設(shè)計(jì)了視音頻網(wǎng)絡(luò)傳輸軟件和WiFi通信應(yīng)用軟件。上述系統(tǒng)在局域網(wǎng)進(jìn)行實(shí)際測(cè)試,并抓取TCP/IP協(xié)議及視音頻數(shù)據(jù)包進(jìn)行簡(jiǎn)要分析。測(cè)試結(jié)果表明,該網(wǎng)絡(luò)傳輸系統(tǒng)實(shí)現(xiàn)了嵌入式終端之間以及嵌入式終端和計(jì)算機(jī)之間的視音頻網(wǎng)絡(luò)傳輸功能。本課題設(shè)計(jì)的網(wǎng)絡(luò)傳輸系統(tǒng)也適用于其它救援通信系統(tǒng),具有很強(qiáng)的可擴(kuò)展性。關(guān)鍵詞:通信與信息系統(tǒng);嵌入式系統(tǒng)
