【摘要】：在社会信息化的推动下,人们的生活和工作方式都发生了巨大的变化,同时也对与人们生活息息相关的传统家居生活方式提出了挑战,实现家居生活信息智能化管理俨然成为社会发展的必然趋势。目前国内智能家居的发展还处于初步阶段,主要还是基于有线的方式,但是由于布线成本过高,且不易于维护扩展等因素,很难得到进一步推广。而无线的通信方式不需要额外的布线,更加灵活且易于扩展,特别是近几年无线传感网络技术得到了广泛应用研究,其中包括Wi Fi、蓝牙、Zig Bee等技术。显然,无线智能家居未来将成为智能家居市场的主要力量,引领智能家居的发展方向。然而,目前无线智能家居系统还处于实验室阶段,许多国外的技术并不适合在我国应用。因此,如何实现一套可靠易于扩展且低成本符合我国基本国情的无线智能家居控制系统仍是亟待解决的问题。本文介绍并分析国内外智能家居领域的关键技术以及研究成果,并对嵌入式技术,无线传感网络技术进行研究,设计并实现了一套基于Open Wrt嵌入式系统和Tiny OS无线传感网络技术的无线智能家居控制系统。本设计采用普通家用路由器作为网关,同时也是作为整个家居控制系统的中央控制器,设计采用Open Wrt作为网关系统,并移植搭建嵌入式Web服务器以及嵌入式数据库,通过服务器程序开发,实现用户远程管理。同时为了使系统更加灵活易于扩展,整个系统实行按按区域管理的方案,采用基于Rlink的RT5350方案完成了区域控制器的设计,在区域控制器上开发TCP转串口服务程序,实现消息转发,同时在区域控制器上完成视频传输服务程序,实现了区域视频监控。我们采用基于Tiny OS无线传感网络技术,实现家庭内部终端设备的无线短距离通信,并完成相应无线传感网络节点的软硬件设计。用户可以使用电脑或者移动智能终端通过网络连接到网关,然后使用浏览器实现家庭设备控制,家居环境查询以及区域视频监控,同时也可以对家居设备进行添加删除管理操作。最后我们完成了原型系统的搭建,并对整个系统进行了稳定性和功能性测试。
[Abstract]:Under the impetus of social informatization, people's life and working style have undergone tremendous changes, but also to people's life closely related to the traditional home life style has put forward a challenge. The realization of intelligent management of household life information has become an inevitable trend of social development. At present, the development of domestic smart home is still in the initial stage, mainly based on cable, but because of the high cost of wiring, It is difficult to maintain and extend, and it is difficult to be popularized further. Wireless communication is more flexible and easy to expand without additional cabling. Especially, wireless sensor network technology has been widely used in recent years. These include Wi Fiand Bluetooth Zig Bee and so on. Obviously, wireless smart home will become the main force in the smart home market in the future, leading the development direction of smart home. However, wireless smart home system is still in the laboratory stage. Many foreign technologies are not suitable for application in China. How to realize a set of wireless intelligent home control system which is reliable and easy to expand and low cost is still an urgent problem to be solved. This paper introduces and analyzes the key technologies and research results in the field of smart home at home and abroad. And the embedded technology, wireless sensor network technology is studied, A wireless intelligent home control system based on Open Wrt embedded system and Tiny OS wireless sensor network technology is designed and implemented. At the same time, as the central controller of the whole home control system, the design adopts Open Wrt as the gateway system, and transplant and build the embedded Web server and embedded database, through the server program development, At the same time, in order to make the system more flexible and easy to expand, the whole system is managed by region, and the design of regional controller is accomplished by RT5350 scheme based on Rlink. The TCP to serial port service program is developed on the local controller to realize message forwarding, while the video transmission service program is completed on the local controller, which realizes the regional video surveillance. We adopt the wireless sensor network technology based on Tiny OS. The wireless short distance communication of the terminal devices in the home is realized, and the hardware and software design of the corresponding wireless sensor network node is completed. The user can connect to the gateway through the network by using the computer or the mobile intelligent terminal. Then using the browser to achieve home device control, home environment query and regional video monitoring, at the same time can also add and delete the home device management operations. Finally, we completed the prototype system, The stability and function of the whole system are tested.
