【摘要】：智能家居作為物聯(lián)網(wǎng)的一個分支,是物聯(lián)網(wǎng)領(lǐng)域最貼近生活的研究方向。智能家居是以家庭住宅為平臺,以家居生活為應(yīng)用背景,通過結(jié)合嵌入式、互聯(lián)網(wǎng)、智能硬件、控制自動化等技術(shù),實現(xiàn)家居設(shè)備的智能化管理。在智能家居領(lǐng)域的相關(guān)產(chǎn)品中,網(wǎng)關(guān)設(shè)備是智能家居領(lǐng)域的重點研究對象。智能家居網(wǎng)關(guān)的主要功能包括三部分:組建內(nèi)部網(wǎng)絡(luò),進行協(xié)議轉(zhuǎn)換,與外部網(wǎng)絡(luò)通信。作為智能家居系統(tǒng)的核心部分,通過網(wǎng)關(guān)設(shè)備對家居終端設(shè)備進行網(wǎng)絡(luò)化控制,可以使現(xiàn)階段智能家居系統(tǒng)智能化程度和實用性不足的問題得到改善。目前市場上的智能家居產(chǎn)品功能較單一,通信方式種類繁多,且產(chǎn)品與客戶端多采用一對一的控制模式,產(chǎn)品間數(shù)據(jù)不能互通。這些問題的存在大大降低了用戶的體驗性及家居系統(tǒng)的智能化程度。為了解決這些問題,本文開發(fā)了一種新類型的網(wǎng)關(guān)設(shè)備。本文對大量的智能家居領(lǐng)域的文獻資料進行分析,介紹國內(nèi)外的智能家居發(fā)展現(xiàn)狀,并分析智能家居的發(fā)展歷史,闡述智能家居未來的發(fā)展趨勢。同時對當下市面上的主流智能家居產(chǎn)品進行了調(diào)查,對家居網(wǎng)關(guān)設(shè)備存在的缺點進行說明,并結(jié)合WiFi、ZigBee、藍牙以及嵌入式技術(shù)設(shè)計新類型的家居網(wǎng)關(guān)設(shè)備。本文的研究包括以下幾方面:(1)分析智能家居系統(tǒng)的體系架構(gòu)以及現(xiàn)階段的發(fā)展形勢,針對現(xiàn)階段的智能家居產(chǎn)品通信方式種類多,產(chǎn)品兼容性差,網(wǎng)關(guān)設(shè)備冗余,家居產(chǎn)品互聯(lián)不便的問題提出一種解決方案,即開發(fā)一種新類型的智能家居網(wǎng)關(guān)設(shè)備。(2)以家庭住宅為應(yīng)用背景,重點對藍牙及ZigBee技術(shù)的網(wǎng)絡(luò)建立和數(shù)據(jù)傳輸過程進行分析和設(shè)計,結(jié)合WiFi技術(shù),組建了智能家居系統(tǒng)的內(nèi)網(wǎng)環(huán)境。家居智能產(chǎn)品通過連接網(wǎng)關(guān)就可以實現(xiàn)設(shè)備之間的數(shù)據(jù)交互。(3)對智能家居網(wǎng)關(guān)設(shè)備的硬件部分進行設(shè)計。主要對使用的藍牙模塊、ZigBee模塊及WiFi模塊進行詳細介紹,結(jié)合Arduino串口擴展板和Raspberry Pi嵌入式單元完成網(wǎng)關(guān)設(shè)備的硬件設(shè)計。(4)對智能家居網(wǎng)關(guān)設(shè)備的軟件部分進行設(shè)計。通過對網(wǎng)關(guān)設(shè)備需要實現(xiàn)的功能進行分析,結(jié)合OpenWrt操作系統(tǒng),通過多線程模塊化的方式設(shè)計本地服務(wù)器以及遠程通訊等應(yīng)用程序。最終實現(xiàn)客戶端對家居設(shè)備的近程以及遠程管理,以及家居環(huán)境信息的感知采集,完成智能家居網(wǎng)關(guān)設(shè)備的軟件系統(tǒng)的設(shè)計。本文設(shè)計開發(fā)的智能家居網(wǎng)關(guān)設(shè)備創(chuàng)新性的使用多種無線接入方式,同時具備近程和遠程兩種連接方法,解決多通信方式的智能家居終端設(shè)備引起的通信不兼容問題,使不同通信類型的設(shè)備之間的數(shù)據(jù)可以進行交互,在大大節(jié)約網(wǎng)關(guān)設(shè)備成本的同時提高了智能家居系統(tǒng)的擴展性和智能性。
[Abstract]:As a branch of the Internet of things, smart home is the most close to life research direction in the field of Internet of things. Smart home is based on family residence as the platform, with home life as the application background, through the integration of embedded, Internet, intelligent hardware, control automation and other technologies to realize the intelligent management of home equipment. Gateway equipment is the key research object in the field of smart home. The main functions of the smart home gateway include three parts: the formation of the internal network, the protocol conversion, and the communication with the external network. As the core part of the intelligent home system, the network control of the home terminal equipment through the gateway equipment can make the present stage intelligent. The problem of intelligent home system intelligence and lack of practicability has been improved. At present, the smart home products on the market have a single function, a wide variety of communication methods, and the products and clients use one to one control mode, and the data between products can not be interconnected. These problems have greatly reduced the user's experience and home system. In order to solve these problems, this paper develops a new type of gateway equipment. This paper analyzes the literature of a large number of smart home fields, introduces the development status of smart home home and abroad, analyzes the development history of smart home, and expounds the development trend of smart home in the future. At the same time, the market is on the market. The mainstream smart home products are investigated, the shortcomings of the home gateway equipment are explained, and the new types of home gateway devices are designed with WiFi, ZigBee, Bluetooth and embedded technology. The research of this paper includes the following aspects: (1) analyzing the architecture of the smart home system and the development situation at the present stage, aiming at the present order There are many types of smart home products, poor compatibility, redundancy of the products, and inconvenient interconnection of home products. It is a solution to develop a new type of smart home gateway. (2) the network building and data transmission process of blue teeth and ZigBee technology are focused on the application background of home housing. In the line analysis and design, combined with WiFi technology, the internal network environment of the smart home system is set up. The home intelligent product can realize the data interaction between the devices through the connection gateway. (3) the hardware part of the smart home gateway device is designed. The Bluetooth module, the ZigBee module and the WiFi module are introduced in detail, and the Ar is combined with the system. Duino serial port expansion board and Raspberry Pi embedded unit complete the hardware design of gateway equipment. (4) the software part of the smart home gateway equipment is designed. Through the analysis of the functions needed by the gateway equipment, combined with the OpenWrt operating system, the local server and remote communication are designed by multi thread modularization. The application program finally realizes the client's proximity to the home equipment, remote management, and the sensing collection of the home environment information, and completes the design of the software system of the smart home gateway equipment. The design and development of the intelligent home gateway device uses a variety of wireless access methods and has two connections in the near and remote connections. Methods to solve the incompatible problem of communication incompatibility caused by the intelligent home terminal equipment with multi communication mode, so that the data between different types of communication devices can be interacted. It greatly saves the cost of the gateway equipment and improves the scalability and intelligence of the intelligent home system.
