【摘要】：随着电子信息技术的飞速发展以及IT产业向传统建筑产业和人们生活渗透，智能家居实现了室内外信息沟通、远程设备控制、监测等功能，为人们提供了舒适安全的生活环境，并逐渐成为当前热点。本文在分析目前智能家居国内外现状以及未来发展趋势的基础上，设计开发了以ARM处理器和Linux操作系统为核心的智能家居网络系统。将网络视频监控系统与家居控制融合在一个ARM-Linux平台上，系统小巧节约且基本满足家居控制要求。本文首先分析比较几种嵌入式系统方案，针对智能家居设计原则以及需求分析，确定选用ARM11处理器S3C6410作为智能家居控制系统的控制核心，并对核心电路进行了研究和外围电路的拓展；移植Linux3.01作为操作系统，并对内核进行裁剪。选取B/S模式作为软件系统开发模型，搭建系统软硬件开发环境。接着在开发平台上建立起智能家居远程控制的基本架构。以BOA作为系统的WEB服务器，WEB浏览器作为客户端，完成主要设备的驱动程序设计，基于HTTP传输协议实现手机、PC等多智能终端远程控制功能；并详细阐述了网络传输协议的选择和客户端WEB网页设计。最后完成V4L2图像采集、H.264编解码、RTP传输、Ffmpeg解码、SDL显示、Activex插件等多项任务，形成家居控制和视频监控功能的融合；分析比较了几种视频编码技术方案，详细分析了H.264硬编码技术的嵌入式应用和多媒体实时传输协议RTP的封包机制。整个设计基本实现了智能家居监控系统的各项功能，经过测试，系统满足设计要求，，并具有集成度高、成本低、可靠性高、稳定性好，功耗低等特点。
[Abstract]:With the rapid development of electronic information technology and the penetration of IT industry into the traditional construction industry and people's life, smart home realizes the functions of indoor and outdoor information communication, remote equipment control, monitoring and so on, which provides people with comfortable and safe living environment. And gradually become the current hot spot. Based on the analysis of the current domestic and international situation and the future development trend of smart home, this paper designs and develops an intelligent home network system based on arm processor and Linux operating system. The network video monitoring system and home control are combined on an ARM-Linux platform. The system is compact and economical and basically meets the requirements of home control. In this paper, several embedded system schemes are analyzed and compared. According to the design principle and requirement analysis of smart home, ARM11 processor S3C6410 is chosen as the control core of smart home control system. The core circuit is researched and the peripheral circuit is extended, Linux 3.01 is transplanted as the operating system, and the kernel is cut out. The B / S model is selected as the software system development model, and the software and hardware development environment is built. Then the basic architecture of intelligent home remote control is established on the development platform. Taking BOA as the system's Web server and Web browser as the client, the driver of the main equipment is designed, and the remote control function of mobile phone and PC is realized based on HTTP transmission protocol. And elaborated the network transmission protocol choice and the client Web page design in detail. Finally, several tasks such as V4L2 image acquisition, H.264 encoding and decoding, RTP transmission, Ffmpeg decoding, SDL display ActiveX plug-in and so on, are completed to form the fusion of home control and video surveillance functions, and several video coding technology schemes are analyzed and compared. The embedded application of H.264 hard coding technology and the packet mechanism of multimedia real time transmission protocol RTP are analyzed in detail. The whole design basically realizes the functions of the intelligent home monitoring system. After testing, the system meets the design requirements, and has the characteristics of high integration, low cost, high reliability, good stability, low power consumption and so on.
