【摘要】：当前中国正处于经济和科学技术突飞猛进的阶段，高科技在生活中的应用随处可见，越来越多的人对日常家庭生活的舒适程度要求越来越高，智能家居应运而生。智能家居系统将普通的家电设备通过特殊的技术实现互联，形成一个智能化的家庭网络，为人们的生活带来新奇的体验和变革。本文通过了解智能家居的发展历史，国内外的研究现状，分析了当前存在的智能家居系统的优缺点，根据市场需求提出了对外部网络接入方式以及家庭内部网络的组建形式两点改进方案。通过对当前的市场需求的研究，设计了一套嵌入式的智能家居系统，在外部网络连接中采用多种接入技术，利用WiFi、GPRS和因特网实现客户端与家庭网关的连接，同时在家庭内部网络中创新采用ZigBee通信协议组建无线传感器网络，实现家庭内部的无线网络互连。随后介绍了中央控制器和控制终端设计，概述了系统的整体框架和使用的关键技术，包括外部网络的WiFi、GPRS、因特网和家庭内部网络中的ZigBee通信协议。根据需求设计了中央控制器和控制终端的硬件结构，详细介绍了其中各接口和模块的功能和作用。由于当前没有一款针对廉价芯片的ZigBee全开源的协议栈，，本文进行了针对TI公司生产的CC2530射频芯片的ZigBee协议栈的开发，片上操作系统采用轻量级系统Contiki，利用其事件驱动机制搭建协议栈的物理层与MAC层服务程序，实现多点对多点的可靠数据传输。最后利用已经实现的协议栈完成智能家居系统中家庭内部网络通信，设计ZigBee控制器和控制终端软件，实现用户对家电设备的远程控制。在温度监控系统的数据传输中加入分布式信源编码，通过数据压缩的方式减少网络中的数据收发量，从而降低节点能量消耗，同时设计上位机控制程序进行反向控制和数据的实时显示。
[Abstract]:At present, China is in the stage of rapid development of economy and science and technology. The application of high technology in life can be seen everywhere. More and more people are demanding more and more comfortable degree of daily family life, and smart home emerges as the times require. The smart home system interconnects common household appliances through special technology, and forms an intelligent home network, which brings novel experiences and changes to people's lives. This paper analyzes the advantages and disadvantages of the existing smart home system through the understanding of the development history of smart home and the current research situation at home and abroad. According to the market demand, this paper puts forward two improvements to the external network access mode and the formation of the home internal network. Through the research of the current market demand, an embedded intelligent home system is designed, which uses various access technologies in the external network connection, and realizes the connection between the client and the home gateway by using WiFiGPRS and Internet. At the same time, the wireless sensor network (WSN) is constructed by using ZigBee protocol in the home internal network to realize the wireless network interconnection within the home. Then the design of the central controller and the control terminal is introduced. The overall framework and key technologies of the system are summarized, including the WiFiGPRS of the external network, the ZigBee communication protocol in the Internet and the internal network of the home. The hardware structure of the central controller and the control terminal is designed according to the requirement, and the functions and functions of each interface and module are introduced in detail. Because there is not a fully open source ZigBee protocol stack for cheap chips, this paper develops a ZigBee protocol stack for CC2530 RF chips produced by TI. The operating system on chip adopts the lightweight system Contiki and uses its event-driven mechanism to build the physical layer and MAC layer service program of the protocol stack to realize the reliable multi-point to multi-point data transmission. Finally, the network communication within the home is completed by using the protocol stack, and the ZigBee controller and the control terminal software are designed to realize the remote control of the household appliances. The distributed source coding is added to the data transmission of the temperature monitoring system to reduce the amount of data received and received in the network by the way of data compression, thus reducing the energy consumption of the node. At the same time, the upper computer control program is designed for reverse control and real-time display of data.
