【摘要】：随着全球经济、通信技术和互联网技术的不断发展以及人们对更好生活品质的追求，家居自动化、智能化和舒适化已成为了发展的趋势。由于如今全球资源的匮乏，人们向往着安全便捷环保节能的生活空间，因此将无线通信技术应用于智能家居之中已成为了必然的趋势。本课题来源于下一代互联网光子集成网络终端产业化项目，在三网融合终端模块的基础之上引入ZigBee无线通信组网设计出了基于ZigBee技术和嵌入式Web服务器的智能家居系统。本论文以智能家居系统为研究的对象，以STM32F103为主芯片的ARM控制板为硬件平台，对其移植嵌入式Web服务器，并利用串口通信的方式与ZigBee无线收发模块进行通信并对其进行管理控制，用户能够通过电脑计算机的浏览器查询或者更改家居中电器的信息和状态，，从而实现智能家居的远程监控系统。本系统已实现的功能有：控制家电设备的开关、采集住宅内的温度数据、人体入侵报警、烟雾报警等异常状态。本论文的主要工作如下： (1)简要介绍了智能家居系统在国内外的现状和发展趋势、ZigBee无线通信技术及Z-Stack协议栈的相关概念； (2)设计出了本系统的硬件方案，包括ZigBee模块芯片选型和各功能模块的外围电路设计等等； (3)设计出了本系统的软件方案，包括ARM控制器的工作流程、ZigBee终端节点和协调器节点各个模块的工作流程，以及嵌入式Web服务器设计。 (4)完成了系统的硬件设计，并对最终的产品进行测试，包括系统功能测试、ZigBee节点通信距离测试、网络节点重启测试及各个功能模块测试等，并进行了具体的分析。经过一系列的测试，验证本系统基本达到了对家庭信息进行智能化控制的目的，具有操作简单、功能强大、功耗低等优良特性，以及广阔的应用前景。
[Abstract]:With the continuous development of global economy, communication technology and Internet technology and people's pursuit of better quality of life, home automation, intelligence and comfort have become the trend of development. Due to the shortage of global resources, people aspire to the safe, convenient, environment-friendly and energy-saving living space, so it has become an inevitable trend to apply wireless communication technology to smart home. This project comes from the industrialization project of the next generation Internet photonic integrated network terminal. On the basis of the three-network convergence terminal module, a smart home system based on ZigBee technology and embedded Web server is designed by introducing ZigBee wireless communication network. In this paper, the smart home system as the object of study, STM32F103 as the main chip of the ARM control board as the hardware platform, to transplant its embedded Web server, And uses the serial communication way to communicate with the ZigBee wireless transceiver module and carries on the management control to it, the user can inquire through the computer browser or change the home electrical apparatus information and the status, So as to realize the remote monitoring system of smart home. The functions of this system include: to control the switch of home appliances, to collect the temperature data in the house, to alarm the intrusion of human body, to alarm the smoke and so on. The main work of this paper is as follows: (1) the present situation and development trend of smart home system at home and abroad, ZigBee wireless communication technology and the related concepts of Z-Stack protocol stack are briefly introduced. (2) the hardware scheme of the system is designed, including the chip selection of ZigBee module and the design of peripheral circuit of each functional module. (3) the software scheme of the system is designed, including the workflow of ARM controller, the workflow of each module of ZigBee terminal node and coordinator node, and the design of embedded Web server. (4) the hardware design of the system is completed, and the final product is tested, including the system function test, the ZigBee node communication distance test, the network node restart test and each function module test and so on. Through a series of tests, it is verified that the system basically achieves the purpose of intelligent control of home information. It has the advantages of simple operation, powerful function, low power consumption, and broad application prospects.
