【摘要】：随着我国经济的高速发展以及信息通信技术、互联网技术、控制技术等科技的进步,人们对高质量家居环境期待指数显著提高,比如家庭环境的舒适性、安全性、效率性等。不仅要求家居产品具备结构简单可操作性强,更要求整个系统在系统服务和功能扩展等方面能够做到更加的便捷、轻松、安全。如何让人们拥有一个更加舒适的家居环境已经成为未来家居生活必须要解决的问题。本文设计的智能家居控制终端是在分析了国内外智能家居控制系统发展进程和缺点的基础上,充分利用互联网通信技术、嵌入式技术和电子信息技术将各种家用电器有效的联系在了一起,最终得到了具有安全可靠、易于使用、标准统一的智能家居控制终端解决方案。智能家居控制终端硬件平台采用的是高通的MSM8926为主控芯片,软件开发使用的操作系统是嵌入式Linux操作系统。本课题研究的主要内容如下:(1)系统移植:采用自主编写的bootloader优化内核引导程序,裁剪Linux操作系统并根据智能家居控制终端的硬件需求编写驱动并移植相关驱动。(2)无线组网算法的研究:主要针对无线通信系统进行数学建模,通过对智能家居无线控制网络组网策略的研究,采用改进型的LEACH路由算法和广度优先搜索修复算法实现对各传感器数据的采集和整个系统的控制。(3)PID控制算法的研究:结合光线传感器采集到的亮度信息,通过PWM波输出来控制显示屏和灯光控制系统随周围环境的光线的变化而变化。(4)综合测试:分两个方面对控制终端进行了测试,首先对图形界面系统和各功能模块进行了测试,然后对控制终端无线通信系统进行了仿真测试。经过综合调试,智能家居控制终端能够正常工作,实现了对家庭用电设备管理的网络化、信息化及安全化的目的,满足了用户对家居环境便捷化、实用化及人性化的需求。
[Abstract]:With the rapid development of Chinese economy and the progress of information and communication technology, Internet technology, control technology and so on, the expectation index of high quality home environment is improved, such as comfort, safety, efficiency and so on. It not only requires the household products to have simple structure and strong maneuverability, but also requires the whole system to be more convenient, easy and safe in the aspects of system service and function expansion. How to make people have a more comfortable home environment has become the future home life must be solved. The intelligent home control terminal designed in this paper is based on the analysis of the development process and shortcomings of the intelligent home control system at home and abroad, and makes full use of the Internet communication technology. Embedded technology and electronic information technology have effectively linked all kinds of household appliances, and finally got a safe, reliable, easy to use, unified intelligent home control terminal solution. The hardware platform of smart home control terminal uses MSM8926 of Qualcomm as the main control chip, and the operating system of software development is embedded Linux operating system. The main contents of this research are as follows: the transplant of the system is as follows: the kernel boot program is optimized by bootloader. Research on the algorithm of cutting Linux operating system and compiling driver and transplanting related driver according to the hardware requirement of smart home control terminal: mainly aiming at the mathematical modeling of wireless communication system, Through the research on the network strategy of smart home wireless control network, The improved LEACH routing algorithm and the breadth-first search and repair algorithm are used to realize the research on the data acquisition of each sensor and the control of the whole system. The PWM wave output is used to control the display screen and the light control system, which changes with the changes of the ambient light. The control terminal is tested in two aspects. Firstly, the graphical interface system and the function modules are tested. Then the control terminal wireless communication system is simulated and tested. After comprehensive debugging, the intelligent home control terminal can work normally, realize the purpose of network, information and security of the household electric equipment management, and meet the needs of the user to the home environment convenient, practical and humanized.
