【摘要】：當前中國正處于經(jīng)濟和科學技術突飛猛進的階段，高科技在生活中的應用隨處可見，越來越多的人對日常家庭生活的舒適程度要求越來越高，智能家居應運而生。智能家居系統(tǒng)將普通的家電設備通過特殊的技術實現(xiàn)互聯(lián)，形成一個智能化的家庭網(wǎng)絡，為人們的生活帶來新奇的體驗和變革。 本文通過了解智能家居的發(fā)展歷史，國內(nèi)外的研究現(xiàn)狀，分析了當前存在的智能家居系統(tǒng)的優(yōu)缺點，根據(jù)市場需求提出了對外部網(wǎng)絡接入方式以及家庭內(nèi)部網(wǎng)絡的組建形式兩點改進方案。 通過對當前的市場需求的研究，設計了一套嵌入式的智能家居系統(tǒng)，在外部網(wǎng)絡連接中采用多種接入技術，利用WiFi、GPRS和因特網(wǎng)實現(xiàn)客戶端與家庭網(wǎng)關的連接，同時在家庭內(nèi)部網(wǎng)絡中創(chuàng)新采用ZigBee通信協(xié)議組建無線傳感器網(wǎng)絡，實現(xiàn)家庭內(nèi)部的無線網(wǎng)絡互連。 隨后介紹了中央控制器和控制終端設計，概述了系統(tǒng)的整體框架和使用的關鍵技術，包括外部網(wǎng)絡的WiFi、GPRS、因特網(wǎng)和家庭內(nèi)部網(wǎng)絡中的ZigBee通信協(xié)議。根據(jù)需求設計了中央控制器和控制終端的硬件結構，詳細介紹了其中各接口和模塊的功能和作用。 由于當前沒有一款針對廉價芯片的ZigBee全開源的協(xié)議棧，，本文進行了針對TI公司生產(chǎn)的CC2530射頻芯片的ZigBee協(xié)議棧的開發(fā)，片上操作系統(tǒng)采用輕量級系統(tǒng)Contiki，利用其事件驅動機制搭建協(xié)議棧的物理層與MAC層服務程序，實現(xiàn)多點對多點的可靠數(shù)據(jù)傳輸。 最后利用已經(jīng)實現(xiàn)的協(xié)議棧完成智能家居系統(tǒng)中家庭內(nèi)部網(wǎng)絡通信，設計ZigBee控制器和控制終端軟件，實現(xiàn)用戶對家電設備的遠程控制。在溫度監(jiān)控系統(tǒng)的數(shù)據(jù)傳輸中加入分布式信源編碼，通過數(shù)據(jù)壓縮的方式減少網(wǎng)絡中的數(shù)據(jù)收發(fā)量，從而降低節(jié)點能量消耗，同時設計上位機控制程序進行反向控制和數(shù)據(jù)的實時顯示。
[Abstract]:At present, China is in the stage of rapid development of economy and science and technology. The application of high technology in life can be seen everywhere. More and more people are demanding more and more comfortable degree of daily family life, and smart home emerges as the times require. The smart home system interconnects common household appliances through special technology, and forms an intelligent home network, which brings novel experiences and changes to people's lives. This paper analyzes the advantages and disadvantages of the existing smart home system through the understanding of the development history of smart home and the current research situation at home and abroad. According to the market demand, this paper puts forward two improvements to the external network access mode and the formation of the home internal network. Through the research of the current market demand, an embedded intelligent home system is designed, which uses various access technologies in the external network connection, and realizes the connection between the client and the home gateway by using WiFiGPRS and Internet. At the same time, the wireless sensor network (WSN) is constructed by using ZigBee protocol in the home internal network to realize the wireless network interconnection within the home. Then the design of the central controller and the control terminal is introduced. The overall framework and key technologies of the system are summarized, including the WiFiGPRS of the external network, the ZigBee communication protocol in the Internet and the internal network of the home. The hardware structure of the central controller and the control terminal is designed according to the requirement, and the functions and functions of each interface and module are introduced in detail. Because there is not a fully open source ZigBee protocol stack for cheap chips, this paper develops a ZigBee protocol stack for CC2530 RF chips produced by TI. The operating system on chip adopts the lightweight system Contiki and uses its event-driven mechanism to build the physical layer and MAC layer service program of the protocol stack to realize the reliable multi-point to multi-point data transmission. Finally, the network communication within the home is completed by using the protocol stack, and the ZigBee controller and the control terminal software are designed to realize the remote control of the household appliances. The distributed source coding is added to the data transmission of the temperature monitoring system to reduce the amount of data received and received in the network by the way of data compression, thus reducing the energy consumption of the node. At the same time, the upper computer control program is designed for reverse control and real-time display of data.
