【摘要】：随着生活和科技水平的提高,人们对家居智能化的需求越来越高,方便、舒适、高效、安全的家庭环境是人们现在追求的目标,但现有的智能家居系统却远远不能满足人们的要求,安装复杂,成本高,辐射大,控制不灵敏等各种技术瓶颈制约着智能家居系统的发展。本文通过对现有的智能家居系统进行分析,设计出一种结合无线WiFi和PLC(电力线载波通信)技术的智能家居控制方案,达到综合两者所长,补充两者所短的效果,实现对家居的智能控制,让人们实现“人在路上,家在手中”的美好愿望。本论文首先阐述了智能家居系统研究背景和国内外研究现状,分析目前存在的稳定性差、智能化程度低、成本高、存在辐射危害等不足,提出目前智能家居系统可以采用一种改造方便,成本低廉,以电力线载波通信技术为核心的家居远程智能控制系统。在深入分析系统的需求和设计原则后总结出本系统设计的开发方案和功能要求。接下来对目前智能家居系统的详细组网方式进行分析,找出一种结合有线和无线两种通信方式的组网方法,并总结出系统的总体模块框架和层次结构,将系统的设计工作分为应用层,网络层和硬件物理层三个层次具体开发。在此基础上,硬件层采用自主开发与二次开发的方式完成了系统WiFi-PLC模块和控制模块的硬件设计,网络层利用云端服务器的WebService和Windows服务程序完成了服务端软件的开发,应用层利用安卓手机端开发了智能家居控制客户端软件,实现了智能家居的远程控制,数据的云端存储,多终端的数据同步,设备的自动定时执行等既定功能。论文的最后根据完成的系统软硬件实物进行系统的远程控制、定时任务功能用户数据管理功能以及远程联网控制稳定性等方面进行测试与展示工作。本论文阐述的这种基于WiFi-PLC的智能家居系统最大的优点在于无需额外布线,即插即用,且辐射小,绿色环保,方便用户对自家家居设备的改造。最大的设计亮点在于WiFi-PLC通信模块的设计,其中包含的WiFi和PLC(电力线载波通信)两种芯片使Internet与电力线载波通信完美的结合了起来,让一个个家居设备真正连上了互联网,从而使用户可以随时随地掌控家中智能家居的使用情况。
[Abstract]:With the improvement of life and science and technology, people's demand for intelligent home is higher and higher, convenient, comfortable, efficient and safe family environment is the goal that people pursue now. However, the existing smart home system is far from meeting the requirements of people, complex installation, high cost, large radiation. Various technical bottlenecks such as insensitive control restrict the development of smart home system. This paper analyzes the existing smart home system. A smart home control scheme combining wireless WiFi and PLC (Power Line Carrier Communication) technology is designed, which can integrate the advantages of both, supplement the short effect of both, and realize the intelligent control of home. Let people realize the "people on the road, home in the hands" good wishes. This paper first describes the research background of smart home system and domestic and foreign research status, analysis of the current existence of poor stability, low degree of intelligence. Because of the high cost and radiation hazard, it is suggested that the smart home system can be modified conveniently and the cost is low. Home remote intelligent control system based on power line carrier communication technology. After deeply analyzing the demand and design principle of the system, the development scheme and function requirement of this system are summarized. The detailed networking mode of the system is analyzed. To find out a network method combining wired and wireless communication mode, and summarize the overall module framework and hierarchical structure of the system, the system design work is divided into application layer. The network layer and the hardware physical layer are developed in detail. On this basis, the hardware layer completes the hardware design of the system WiFi-PLC module and control module by the way of independent development and secondary development. The network layer uses the WebService and Windows service program of the cloud server to complete the development of the server software, and the application layer uses the Android mobile phone to develop the smart home control client software. Realize the remote control of smart home, data cloud storage, multi-terminal data synchronization. The automatic timing of equipment execution and other established functions. Finally, according to the completion of the system hardware and software physical object to carry out the remote control of the system. The user data management function of timing task function and the stability of remote network control are tested and demonstrated. The greatest advantage of this smart home system based on WiFi-PLC in this paper is that. No additional wiring is required. Plug and play, and small radiation, environmental protection, easy to users of their own home equipment transformation. The biggest design highlight lies in the design of WiFi-PLC communication module. It contains WiFi and PLC (Power Line Carrier Communication) two kinds of chips to make Internet and power line carrier communication perfect combination, so that one of the real home devices connected to the Internet. So that users can control the use of home smart home at any time and anywhere.
