毕业设计—基于物联网的智能家居设计.doc

摘要 随着物联网技术的发展和人们对物质生活水平的要求的不断提高，人们对生活的安全、舒适、便捷等方面的要求也越来越高。近年来人们对家庭住宅观念发生了巨大改变，智能家居将成为现代化住宅的发展趋势。对于它的研究和开发，是一项有关自动控制、无线连接、无线通信多学科交叉的研究课题。 本文以物联网的发展为背景，通过学习研究物联网的相关技术，明确物联网的关键技术包括：RFID标识技术、传感网技术、M2M技术。在硬件方面，采用了GPRS模块作为远程人机交互手段，接收和发送信息。利用器件组成ZigBee网络实现短距离的无线网络通信，并详细阐述了各硬件模块的功能和实现方法。GPRS模块软件方面，利用AT指令编写程序，实现用户手机的短信收发过程；利用单片机实现了对家用电器的控制。在智能家居控制系统中应用了星型网的网络拓扑，通过ZigBee网实现了节点之间无线通信。 关键词：物联网；智能家居；ZigBee；GPRS；远程控制 ABSTRACT As the development of the Internet of Things，the standards of material life are continually improved. The requires of the safe, comfortable and convenient are also raised. In recent years, there are huge changes on the concept of family house on people’s mind; and the smart home will be the trend of modern house. The research and development of it is about the automatic control, wireless connection and wireless communications study subjects. This article is based on the development of the Internet of Things.By studying the technology of the Internet of Things, and kowing that the key technologys include ：RFID identify the network technology, sensing technology, M2M. In the hardware, the module GPRS is used as the remote interaction of man-machine; by sending and receiving messages. To realize wireless communication in short distance, some equipment are used to form a ZigBee net. And tell the details of every module’s function and method to realize. In GPRS software modules, the program is edited by AT instruction and realized the process of sending and receiving messages. The control of household appliances becomes true by the single chip. Network topology structure of star is applied in the smart house control system; by using the net of ZigBee that the wireless communication between nodes is realized. Key words: Internet of Things; Smart Home; ZigBee; GPRS; Remote Control目录 前言 1 1 绪论 2 1.1 物联网技术概述 2 1.2 智能家居概述 3 1.3 智能家居的发展 3 1.4 智能家居系统的特点 4 1.5 本章小结 4 2 物联网相关通信技术的原理 5 2.1 ZigBee无线技术 5 2.1.1 ZigBee的概念 5 2.1.2 ZigBee的协议栈 5 2.1.3 ZigBee的应用领域和应用前景 10 2.1
