【摘要】：智能家居涉及多种技术,包括网络技术、能源管理控制技术、信息通信技术等。它能够让传统家电设备智能化：能够接收人们的远程指令,也能根据实际的环境状况自动调整参数。近两年来,物联网和移动互联网的蓬勃兴起给智能家居带来了巨大的发展机遇,但是仍旧存在布线混乱、扩展性差以及通信方式单一等问题,在一定程度上影响了智能家居的快速发展。本文以智能家居系统为研究对象,在了解与分析当前智能家居研究现状的基础上,针对传统智能家居存在的若干问题,结合ZigBee、物联网、无线局域网以及移动互联网技术,提出一种基于开源OpenWrt嵌入式操作系统的智能家居系统的设计方案。该系统的设计思路在于：设计制作硬件平台,刷写系统固件,开发安卓客户端程序,提供主界面用于管理智能家居系统,最终实现系统固件的定制、环境监测、家电设备控制和视频监控等功能。论文主要的研究内容包括：首先调研智能家居的研究背景、意义及相关实现技术,确定本文设计的智能家居所需实现的各项功能；选择智能家居系统的整体设计方案,确定硬件和软件的设计框架,分解工作要素,把各个要素的工作落到实处。其次设计制作硬件平台。使用电路板设计工具绘制智能家居终端硬件平台的原理图以及PCB布线,并焊接调试。该智能终端集成了无线路由器和ZigBee网关,实现对家电设备的统一集中控制。再次开发软件系统。搭建嵌入式Linux环境,定制智能家居系统固件、编写软件程序：包括ZigBee通信、红外遥控家电、基于Android的客户端程序以及不同模块的通信协议,完成系统固件定制、环境监测、家电设备控制、视频监控及移动客户端管理等功能。最后,论文对系统功能以及硬件平台的运行状况进行了测试,测试结果表明：基于OpenWrt的智能家居系统稳定性高、扩展性强,支持WiFi和ZigBee两种通信方式,实现了系统固件定制、环境监测、家电设备控制、视频监控及客户端管理等功能。测试结果符合论文预期目标。本系统旨在针对当前智能家居现状提供的一种切实可行的参考设计方案,改善人们的生活质量,具有一定的市场应用价值和研究意义。
[Abstract]:Smart home involves a variety of technologies, including network technology, energy management and control technology, information and communication technology. It can make traditional appliances intelligent: it can receive people's remote instructions, and can automatically adjust parameters according to the actual environmental conditions. In the past two years, the boom of Internet of things and mobile Internet has brought great opportunities for the development of smart home, but there are still some problems such as chaotic wiring, poor scalability and single communication mode. To some extent, it affects the rapid development of smart home. This paper takes smart home system as the research object, on the basis of understanding and analyzing the current research status of smart home, aiming at some problems existing in the traditional smart home, combining ZigBee, Internet of things, wireless LAN and mobile Internet technology. This paper presents a design scheme of smart home system based on open source OpenWrt embedded operating system. The design ideas of the system are as follows: designing and making hardware platform, brushing and writing system firmware, developing Android client program, providing main interface for managing smart home system, finally realizing system firmware customization and environment monitoring. Home appliance equipment control and video surveillance and other functions. The main research contents of this paper are as follows: firstly, the research background, significance and related realization technology of smart home are investigated, and the functions of the smart home designed in this paper are determined, and the overall design scheme of intelligent home system is selected. Define the design framework of hardware and software, decompose the working elements, and carry out the work of each element. Secondly, the hardware platform is designed and manufactured. Use circuit board design tools to draw the schematic diagram of smart home terminal hardware platform and PCB wiring, and welding debugging. The intelligent terminal integrates wireless router and ZigBee gateway to realize unified centralized control of household appliances. Develop the software system again. Build embedded Linux environment, customize the firmware of smart home system, compile software program: including ZigBee communication, infrared remote control home appliance, client program based on Android and communication protocol of different modules, complete system firmware customization and environment monitoring. Home appliance equipment control, video surveillance and mobile client management and other functions. Finally, the function of the system and the running status of the hardware platform are tested. The test results show that the smart home system based on OpenWrt has high stability, strong expansibility, supports two communication modes of WiFi and ZigBee, and realizes the system firmware customization. Environmental monitoring, home appliance control, video monitoring and client management and other functions. The test results are in line with the expected objectives of the paper. The purpose of this system is to provide a practical reference design scheme for the present situation of smart home, improve people's quality of life, have certain market application value and research significance.
