1、基于物联网的智能家居系统设计- - I 基于物联网的智能家居系统设计 摘 要 智能家居系统是利用计算机、嵌入式系统和通信网络技术，将各种家用设施(如照明、安防、家电等)通过家庭网络连接到一起，从而为人们提供更为便利舒 适的生活。传统的智能家居系统一般是通过有线线路布线和进行各种控制和通信的，人们难以脱离各种线缆的羁绊，而且系统的可扩展性能也很差。现代近距无线通信技术的发展，使得人们能够冲破这种束缚，营造更舒适的家居生活。家居网络可以大致分为数据网络和控制网络两大部分，本文主要针对智能家居系统的控制网络相关技术进行研究，并进行了系统设计。 本文主要按照以下几部分展开论述: 首先分析了智能家居系统
2、的一般构成以及控制系统在智能家居的地位，并通过传统智能家居的特点进行分析，指出了目前市场上的智能家居系统的局限性，提出了基于短距无线网络的现代智能家居系统是将来的发展趋势。接着对智能家居控制的系统构架以及相关关键技术进行了分析和比较，指出基于IEEE802.15.4的zigbee技术是目前最适合无线家居控制系统的无线标准，并对该标准进行了深入研究。然后从系统和应用的角度来研究智能家居控制网络，设计了一个基于近距无线技术的智能家居控制演示系统，包括主控制器与传感器、摄像头监控、开关控制等功能节点的设计。 关键词：家居控制网， Zigbee，物联网Things Based System Desig
3、n of Smart Home ABSTRACT Intelligent household system is using a computer, the embedded system and communication network technology, will all sorts of household facilities (such as lighting, security, home appliance, etc) through the family network connectivity to together, thus provide people with
4、more convenient comfortable life. The traditional intelligent household system is generally through the cable line wiring and various control and communication, people is hard to escape the fetters of various cable, and system extensible performance is also very poor. Modern sidewall of wireless com
5、munication technology development makes the people can get the chains, build the household life more comfortable. Household networks can be roughly divided into data networks and control network of two parts, this article mainly aims at intelligent household system control network relevant technolog
