【摘要】 该论文通过对有线网络技术和无线网络技术在智能家居中应用的比较,以及ZigBee与其它几种无线网络技术的比较,最终得出ZigBee无线通信网络技术的低功耗、低速率、低成本等特点满足了智能家居的要求。所以,该论文采用ZigBee作为智能家居系统的无线通信网络技术。该论文是以家居为研究背景,设计了智能家居系统的内网和外网控制系统。内网采用ZigBee无线通信技术对家居进行无线控制。内网涉及的内容包括ZigBee的协议分析,ZigBee无线通信网络的设备类型、网络构造以及网络拓扑结构等。通过对家居环境的分析,确定整个系统将选用的设备类型及网络拓扑结构。外网采用短信猫和GSM网络对家居进行远程控制。外网涉及的内容包括短信猫的操作函数、发送和接收信息等。短信猫采用AT指令对传感器节点进行控制。在系统设计过程中,整个智能家居系统从五个方面进行了研究,包括:1)ZigBee的深入研究,2)整体方案的设计,3)系统硬件的设计,4)系统软件的设计,5)系统测试。整体方案设计研究了该系统的结构组成、网络的选择、传感器的选择及上位机的设计。系统的硬件包括对CC2430无线通信模块和短信猫进行了研究。系统软件包括如何组建新网络、FFD加入网络的流程、RFD加入网络流程、系统报警流程、网络地址的分配及路由的分析等。系统测试包括一个节点的入网测试、多个的节点入网的测试及丢包率的测试。本文采用VC++6.0编写的串口程序来实现系统的数据采集和处理功能。本系统的测试结果表明ZigBee无线通信网络技术能够成功的应用于智能家居并具有良好的效果。更多还原

【Abstract】 With the comparison of the wired network and wireless network technology in the intelligent home, the comparison of several other wireless networking technology and ZigBee in this paper, the final conclution is ZigBee wireless communication network technology which is with low power, low rate, low cost, can meet the requirements of the smart home. So this paper uses ZigBee as wireless communication network technology of a smart home system.This paper uses the home as the research background to design the home’s internal network and external network control system. ZigBee wireless communication within the network using wireless technology for home control. The internal network consists of the ZigBee protocol analysis, ZigBee wireless communication network device type, network structure and network topology structure. By analyzing of Home environment to determine the type of device and network topology of the entire system. External network uses SMS to remote control of domestic cats. The content of external network involves manipulation functions, including SMS cat, sending and receiving information. SMS uses AT commands to the sensor cat control.In the process of designing system, the home system has been studied in five aspects, including :1)deeply ZigBee study 2)the overall program design 3)system hardware design 4)system software design 5)system testing. Describe the overall design of the structure and composition of the system, network selection, sensor selection and design of the host computer. The hardware structure is about CC2430 hardware and hardware structure is about the cat messge. Software describes how to set up a new network, FFD process of joining the network, RFD join the network processes, systems, process alarm, network address allocation and routing analysis. System testing involves one or more network nodes results of the test and packet loss rate test.In this paper, VC + +6.0 is used to program serial port to implement the system data acquisition and processing functions.The results show that the wireless network technology of ZigBee can be successfully applied in smart home.更多还原
