【摘要】：目前,智能家居系统的主要问题是:缺乏低成本、分布式可扩展的远程监控系统;缺乏大容量、双向、实时的通信接入网支持。本文鉴于现有智能家居系统的发展和无线网络技术的研究现状,提出了一种基于无线异构网络的智能家居系统,并通过对系统进行精确的设计,实现了无线异构网络之间的信息交互和智能家居系统的远程监控功能。本文设计了智能家居系统的整体框架,并对系统的主要组成部分和应用功能进行了设计。其中,重点研究了无线网关和无线节点的硬件设计和软件设计,以及异构网络间基于协议转换的通信实现。在硬件方面,无线网关的ZigBee协调器部分和无线节点选用CC2530无线芯片实现ZigBee网络的数据处理和射频收发功能;无线网关的Wi-Fi控制器部分采用CC3200无线芯片,借助于家庭路由将ZigBee网络数据和Wi-Fi网络数据引入到互联网云平台,实现异构网络的信息交互。软件方面,通过研究智能家居系统的应用功能,设计了无线节点的工作模式和ZigBee网络的通信方式;通过组件星型网络,实现了ZigBee网络间数据通信;通过无线网关的程序设计,实现了将ZigBee网络数据、Wi-Fi网络数据引入到互联网云平台;通过协议转换程序的设计,实现了异构网络之间的信息交互。本文最后对整个系统各个通信环节做了测试。测试结果表明:在本文设计的基于无线异构网络的智能家居系统中,传感器的数据采集、基于协议转换的异构网络通信、系统的实时监测和远程控制,都能够满足智能家居系统的应用要求。
[Abstract]:At present, the main problems of smart home system are: lack of low-cost, distributed and extensible remote monitoring system; Lack of large capacity, two-way, real-time communication access network support. In view of the existing smart home system development and wireless network technology research status, this paper proposes a wireless heterogeneous network based smart home system. Through the accurate design of the system, the information exchange between wireless heterogeneous networks and the remote monitoring function of smart home system are realized. The whole frame of smart home system is designed in this paper. The main components and application functions of the system are designed. Among them, the hardware design and software design of wireless gateway and wireless node are studied. And the realization of communication between heterogeneous networks based on protocol conversion. In the aspect of hardware. In the part of ZigBee coordinator and wireless node of wireless gateway, CC2530 wireless chip is used to realize data processing and RF transceiver function of ZigBee network. The Wi-Fi controller part of the wireless gateway uses CC3200 wireless chip to introduce ZigBee network data and Wi-Fi network data to the Internet cloud platform by means of home routing. In the aspect of software, through studying the application function of smart home system, the work mode of wireless node and the communication mode of ZigBee network are designed. The data communication between ZigBee networks is realized by component star network. Through the program design of wireless gateway, the ZigBee network data and Wi-Fi network data are introduced into the Internet cloud platform. Design of protocol conversion program. Finally, the communication links of the whole system are tested. The test results show that the smart home system based on wireless heterogeneous network is designed in this paper. Sensor data acquisition, heterogeneous network communication based on protocol conversion, real-time monitoring and remote control of the system can meet the application requirements of smart home system.
