【摘要】 智能家庭信息网络是集自动化、计算机、通信技术于一体的“3C”系统,它实现了家庭各种信息设备的集中控制、远程监控及各设备之间的信息交换和通信。以家庭网关为突破口作为对家庭信息系统的研究,将有可能在以后的竞争中占据制高点,取得良好的经济和社会效益。 本课题开发的智能家庭信息系统是以实际项目为背景,对基于网络的嵌入式家庭信息系统进行了研究。其中,家庭网关是论文研究的重点,它是智能家庭信息系统的核心部分及系统中用来管理各种信息家用电器以及家居设施控制器最关键的组成部分。 论文充分考虑到家庭信息化网络的现状和未来对多媒体等高速信息流传输的需求,提出了对多媒体等信息设备采用高速传输的有线IEEE1394标准连接形成家庭主网;同时考虑到家庭内部各信息家电(如空调、冰箱、三表三防、甚至是灯光控制等设备)的互连、集中控制、远程访问与控制的需求,以及低成本实现的实际需要和使用灵活性的特点,设计了以中低速传输的无线Bluetooth技术组成家庭控制子网并与家庭主网连接的家庭网络体系总体结构。 信息系统的硬件核心采用S3C2410X开发板并在其基础上扩展了系统所需的功能模块;其操作系统为针对S3C2410X的嵌入式Mizi Linux系统,文中给出了其内核的编译过程,并且针对Linux的实时性不强的问题,提出了一种适合本系统的RTAI+嵌入式Mizi linux的实时解决方案,以及实现了嵌入式Linux的裁减、移植并改进了Linux内核。 深入分析了IEEE1394接口标准和无线Bluetooth组网技术以及它们在将来的广泛应用。 最后,论文深入具体地研究了家庭无线控制子网,通过在开发板S3C2410X上对蓝牙协议栈BlueZ的移植,模拟实现了蓝牙模块与蓝牙手机的连接与互通。更多还原

【Abstract】 Smart home network is a "3C" system concentrating of families automation, computers, communications technology ,it realizes the home centralized control of information appliance, remote survey and control, and the exchange of information and communications between equipments . If we take the research of Home Gateway as a breakthrough to the Smart home system, it will be possible in future to occupy the commanding height of competition, and make good economic and social benefits. The Smart Home system that the paper has reseaeched takes a practical project as a background and bases on the network .The Home Gateway is the focus of the paper, it is the core of the smart home information systems and information management system for home appliances, and the most critical component of facilities controller.The paper fully takes account of the status of home informationization and the demand such as high-speed multimedia transmission of information, put forward to adopting IEEE1394 standard to composit the main home network for the severces like multimedia at high-speed transmission of information;On the same time,the paper takes into account the needs of interconnection, centralized control, remote survey and control, low-cost and the flexibility of all appliances within the home (such as air conditioning, refrigerators, even lighting control equipment),and designs the totel structure of the home network with the wireless Bluetooth technology to realize mini network that join to the main network.The core of system’s hardware used the development board S3C2410X on which it expanses some functional modules;the operating systems is S3C2410X Mizi Linux system, and the paper has given its translation process.As for the weak of real-time Linux,the paper has proposed a solution of double core with RTAI+Mizi Linux.As well the paper has achieved an embedded Linux reductions, and an embedded transplant.The paper thoroughly analyzed IEEE1394 interface standard and wireless Bluetooth network technology and their wider application in the future.Finally, the paper has specifilly researched the wireless control to primary network, and transplanted the BlueZ of Bluetooth agreement to the S3C2410 board , as well as simulated the connection and communation between the Bluetooth modules and the mobile phone network.更多还原
