【摘要】 随着自动化技术、通信技术和网络技术在各个领域的迅速发展,人们的居家生活也正在面临着一场重大的变革。采用高档嵌入式微控制器及其外围器件作为硬件平台,以嵌入式操作系统为软件核心的远程家庭信息监控系统是智能家电控制的一个新的发展方向。 论文以实际的科研项目为背景,对远程家庭信息监控系统进行了研究,提出了基于S3C44BOX微控制器、以嵌入式操作系统uClinux为核心的远程家庭信息监控系统设计方案,并且从系统的扩展升级和性价比出发,具体设计了满足平台要求的嵌入式硬件系统,包括FLASH ROM、SDRAM等。 分析了uC/OS-Ⅱ和uCLinux两种操作系统的异同,重点研究了uClinux操作系统的运行机制及其在S3C44BOX微控制器的启动过程,并对bootloader(启动代码)进行了设计。通过对uClinux内核的加载、二级中断矢量表的定义及对编译环境的安装和交叉编译,最终实现了uClinux内核在硬件系统上的移植。 详细剖析了TCP/IP协议,并且基于该协议对远程家庭信息监控系统采用网络接口芯片RTL8019AS以以太网的联网方式,实现了信息家电的组网及对信息的远程传输与控制。 论文完成了远程家庭信息监控系统的硬件平台架构的设计,嵌入式操作系统的移植,为以后的远程信息家庭监控系统的开发提供了一个平台。更多还原

【Abstract】 With the rapid development of automation technology, communications technology and network technology in all fields ,and people’s home life is also facing an important change. It is a new trend of intelligent appliances control taking an embedded operating system as the remote home Monitoring system core, while using a high-grade embedded micro-controller and its peripheral device as a hardware platform.This paper, which has an actual item background, carries on a research to embedded system of home information remote monitoring. The thesis puts forward to this scheme of the system which is composed of S3C44B0X micro controller and embedded operating system uClinux. To upgrade the system and get a good Xingjiabi, this platform is designed to meet the specific requirements of an embedded hardware system, including Flash ROM, SDRAM, etc.Comparing the operating systems uC/OS-II with uCLinux, the paper focuses on the study of uClinux operating system operation mechanism and the activation process S3C44B0X micro controller, and design the bootloader. The system which loads uClinux kernel, defines of secondary interruption vector table and installs and cross-translant the translation environment, ultimately transplant the uClinux system into the hardware system.Analyzing TCP/IP protocol in detail, the system based on the protocol adopts Ethernet interface chip RTL8019AS to make up the network of information appliances remote, transmits information and controls it.The paper designs home information remote monitoring hardware platform architecture and transplants embedded operating system, which provides a subsequent development platform for embedded system of home information remote monitoring.更多还原
