1、新疆大學(xué)碩士學(xué)位論文摘要摘要隨著計(jì)算機(jī)技術(shù)、通信技術(shù)的飛速發(fā)展,使底層監(jiān)測設(shè)備與]nternet/]ntranet無縫連接,真正做到遠(yuǎn)程監(jiān)測成為工業(yè)發(fā)展越來越迫切的需求。但許多傳統(tǒng)的工業(yè)監(jiān)控設(shè)備基于RS-485、RS-232、CAN-BUS等通信接口構(gòu)成輕量級網(wǎng)絡(luò),無法直接同以太網(wǎng)連接,故利用嵌入式技術(shù)設(shè)計(jì)性價(jià)比高的工業(yè)以太網(wǎng)網(wǎng)關(guān)實(shí)現(xiàn)異構(gòu)網(wǎng)絡(luò)互連,實(shí)現(xiàn)真正的遠(yuǎn)程控制。工業(yè)以太網(wǎng)網(wǎng)關(guān)設(shè)計(jì)主要由硬件設(shè)計(jì)和軟件設(shè)計(jì)兩部分組成。硬件系統(tǒng)的核心選擇了Samsung公司的$3C2410處理器,以北京博創(chuàng)公司的核心板為基礎(chǔ)設(shè)計(jì)了硬件模塊。論文對處理器,存儲器及網(wǎng)絡(luò)控制器等重要器件進(jìn)行了分析。軟件上
2、移植了IAnux操作系統(tǒng),分析了系統(tǒng)內(nèi)核,基于應(yīng)用對網(wǎng)絡(luò)模塊進(jìn)行了優(yōu)化,設(shè)計(jì)了系統(tǒng)Web測試頁面,集成了串口通信協(xié)議。文中首先介紹了嵌入式網(wǎng)關(guān)系統(tǒng)、嵌入式系統(tǒng)以及ARM體系結(jié)構(gòu)的相關(guān)知識;然后詳細(xì)討論了系統(tǒng)的硬件電路設(shè)計(jì)及單元電路調(diào)試:接著概述了Linux操作系統(tǒng)的基本知識,在此基礎(chǔ)上討論了該操作系統(tǒng)在本嵌入式系統(tǒng)中的移植,包括內(nèi)核的修改、裁減和編譯,Bootloader的原理和基于本系統(tǒng)的程序設(shè)計(jì),系統(tǒng)驅(qū)動程序的設(shè)計(jì),Web服務(wù)器的實(shí)現(xiàn),串口通信協(xié)議的移植等;最后給出了針對網(wǎng)關(guān)系統(tǒng)的配置文件設(shè)計(jì)、修改和實(shí)驗(yàn)室網(wǎng)關(guān)的調(diào)試結(jié)果。實(shí)驗(yàn)結(jié)果表明。該設(shè)計(jì)完成了基本要求功能?;趹?yīng)用對網(wǎng)絡(luò)模塊
