【摘要】 应用基于Linux的嵌入式Internet系统是监控领域新的发展趋势。嵌入式Internet将改变现有的监控系统体系结构，提高系统可扩展性，降低成本。本文在这样的前提下，研究了基于Linux的嵌入式Internet技术。 文章首先概括性地介绍了嵌入式系统的相关理论技术和监控系统的演变，以及嵌入式Internet系统在监控系统中的应用可能，提出了基于嵌入式Web服务器的监控体系结构。然后，详细研究分析了如何利用Linux构建嵌入式Internet服务系统，其中主要包括下面几个方面的内容：如何引导嵌入式Linux系统；如何修改Linux内核以适应嵌入式应用的需要，这其中主要分析了对虚拟内存机制的修改；如何在嵌入式Linux系统中挂接文件系统；开发硬件设备驱动程序的方法；如何将嵌入式Linux系统接入Internet。最后，本文在运行于x86处理机的Linux平台上模拟实现一个具有基本功能的嵌入式Web服务器；并且讨论了后续开发的技术方向。更多还原

【Abstract】 The application of Embedded Internet System based upon Linux is a tendency in the field of remote monitoring and supervision. Embedded Internet will change the architecture of monitoring and supervision system, emhance the system expansibility and reduce the cost. In this premise, this paper works over the Embedded Internet technology based upon Linux.The paper first tells about the basic theory and correlative technology about embedded system and brings forward the architecture of monitoring and supervision system based upon Embedded Web Server. Then it works over the methods of constructing the embedded Internet service system with Linux which mainly include the following aspects: how to boot Embedded Linux System; how to revise the Linux Kernel to adjust it to embedded application, especially how to revise the virtual memory mechanism; how to mount a file system to Embedded Linux System; methods of developing device drivres; how to connect Embedded Linux System to Internet. At last, an Embedded Web Server with fundamental functions is implemented on the Linux platform runned with x86 CPU, and further developing orientation is discussed.更多还原
