【摘要】 随着计算机技术和网络技术的飞速发展，各种层次硬件的出现以及硬件水平不断提高，出现了以嵌入式设备为主的监控仪器仪表，而且信息家电的网络化已经成为趋势。人们希望嵌入式系统能接入Internet具有web服务器的功能，可以在任何地点，使用IE浏览器查看嵌入式系统的实时状态、并能对嵌入式系统进行远程监测、控制、诊断和配置等操作。目前在网络应用层数据的传输和表达使用最广泛的协议就是Http协议，所以嵌入式设备通过Internet网络远程监控中数据的传输和表达的一个主要方向就集中在了针对嵌入式系统的Web服务器(简称嵌入式Web服务器)上。本论文以云南省自然科学基金项目“嵌入式开放平台在家电网络信息化中的研究与实现”课题的设计与实现为背景，在对嵌入式信息家电平台进行了系统分析后，利用以ARM+linux技术为支撑，进行了嵌入式系统的软硬件平台的搭建，深入介绍了一个非常适合应用于嵌入式系统的Web服务器的工作原理，重点实现了一个嵌入式Web服务器的移植，还针对嵌入式信息家电平台中的用户登录、红外控制电视机、蓝牙家电控制、电灯管理等应用进行了CGI(Common Gateway Interface，公共网关接口)程序设计，在CGI动动念页面的程序设计上，也在较大程度上考虑了系统的安全性、实时性和稳定性，针对客户端请求的操作，系统提供了友好统一的运行界面。用户可通过IE浏览器登录服务器端运行的CGI动态页面查看信息家电的运行状态，并可根据用户请求调用相应的模块实现对信息家电进行远程控制。最后对系统的运行测试情况进行了描述和说明。总结了系统中存在的问题及下一步工作的展望。更多还原

【Abstract】 As the network is being more and more widely applied and the hardware is advancing rapidly, it is necessary and possible to connect monitor instruments and modern computerized home applications which are embedded system in essence into Internet. The people hope that embedded system can connect with internet ,having web fuction in order that they can look about the situation of embedded system anytime and control remotely. Because most of the data presented and transplanted through Internet are in the format of HTTP standard, the solution of presentation and transportation monitor information is focused on the web server embedded into the embedded systems, short as Embedded Web Server.Based on project "the research and implement of open embedded platform in home network" from Yunnan Province,after analyzing the whole embedded platform of imformation appliance,we makeup the software and hardware platform which is supported on arm and embedded linux technology. A web server that is suit for embedded system is introduced and studied thoroughly. The paper described detailedly the process of transplanting web server and made cgi programming in allusion to users’ login,bluetooth application, Irda for controlling television ,lamp management. we thought over the security,real-time and stability of system to greate extent while programming cgi. Users can login the system in IE brower by united interface and call the relevant module to realize remote control about imformation appliance.In the last part of dissertation,we described the information about testing and system running and summarized the weakness of the system and pointed out the next research about the system.更多还原
