【摘要】：物聯(lián)網(wǎng)技術(shù)在現(xiàn)代智能家居系統(tǒng)中的應(yīng)用不斷成熟,對比現(xiàn)有智能家居系統(tǒng)在家庭內(nèi)網(wǎng)的網(wǎng)絡(luò)訪問局限性,我們設(shè)計并改進了一種基于物聯(lián)網(wǎng)的全網(wǎng)絡(luò)化智能家居系統(tǒng)。從智能家居的系統(tǒng)需求出發(fā),文章介紹系統(tǒng)的功能模塊定制,網(wǎng)絡(luò)控制系統(tǒng)的選擇與設(shè)計,基于功能需求的軟硬件設(shè)備定制開發(fā),以及系統(tǒng)實現(xiàn)的優(yōu)越性對比分析；著重介紹智能家居的網(wǎng)絡(luò)控制系統(tǒng)、智能網(wǎng)關(guān)架構(gòu)、數(shù)據(jù)庫訪問技術(shù)在人機交互的應(yīng)用以及音視頻處理的應(yīng)用,重視智能網(wǎng)關(guān)訪問安全性。經(jīng)過對系統(tǒng)集成測試分析,該系統(tǒng)能夠滿足人們對現(xiàn)代智能家居系統(tǒng)易用性、可用性以及便利性的需求。 本文的主要工作： 1.智能家居系統(tǒng)的整體硬件平臺搭建：根據(jù)人們對于家居系統(tǒng)在安防監(jiān)控、家電操作、照明管控、遠程能源付費、遠程網(wǎng)絡(luò)監(jiān)督以及智能語音交互等方面的功能需求,定制完成各傳感單元、互聯(lián)網(wǎng)絡(luò)以及家居網(wǎng)絡(luò)控制平臺的鋪設(shè)與安裝。 2.家居網(wǎng)絡(luò)控制系統(tǒng)架構(gòu)的選擇：通過分析對比各系統(tǒng)架構(gòu)優(yōu)劣,確定本系統(tǒng)網(wǎng)絡(luò)控制架構(gòu)的選擇。 3.智能語音識別的實現(xiàn)：采用微軟語音識別開發(fā)包speech SDK5.1,根據(jù)命令識別模式,定制語音識別字典,實現(xiàn)高準(zhǔn)確度語音識別。 4.遠程視頻監(jiān)控的實現(xiàn)：采用JPEG圖像編碼,將視頻幀以壓縮碼流的形式由系統(tǒng)服務(wù)器傳輸至客戶端,用戶可通過網(wǎng)絡(luò)訪問來實時監(jiān)控家居狀態(tài)；同時對于固定攝像頭,拍攝背景相同,應(yīng)用背景掩膜,為入侵檢測提供可靠且準(zhǔn)確的輔助。 5.各功能模塊與嵌入式微處理器的通信機制選擇,以及通信程序設(shè)計。 6.家居系統(tǒng)網(wǎng)絡(luò)訪問站點的設(shè)計與實現(xiàn)：與本系統(tǒng)改進前的客戶端家居控制平臺形成對比,系統(tǒng)網(wǎng)絡(luò)訪問平臺在用戶身份驗證、家居狀態(tài)反饋和家居網(wǎng)絡(luò)訪問安全等方面進行了改進。 7.系統(tǒng)運行測試分析,總結(jié)目前的系統(tǒng)優(yōu)缺點,介紹系統(tǒng)的改進計劃。
[Abstract]:The application of Internet of things technology in the modern smart home system is maturing, compared with the limitations of the existing smart home system in the home network access, We design and improve a fully networked intelligent home system based on the Internet of things. According to the system requirements of smart home, this paper introduces the customization of the system function module, the selection and design of the network control system. Customization development of hardware and software equipment based on functional requirements, and comparative analysis of the advantages of the system implementation, focusing on the introduction of intelligent home network control system, intelligent gateway architecture, The application of database access technology in human-computer interaction and audio and video processing attaches importance to the security of intelligent gateway access. After testing and analyzing the system integration, the system can satisfy the ease of use of modern smart home system. Usability and convenience requirements. The main work of this paper is as follows:. 1. Building the whole hardware platform of smart home system: according to the functional requirements of the home system in security monitoring, home appliance operation, lighting control, remote energy payment, remote network supervision and intelligent voice interaction, etc. The installation and installation of sensor unit, internet and home network control platform are customized. 2. The choice of home network control system architecture: by analyzing and comparing the advantages and disadvantages of each system architecture, the choice of the system network control architecture is determined. 3. The realization of intelligent speech recognition: Microsoft speech recognition development kit speech SDK5.1 is used to customize the speech recognition dictionary according to the command recognition pattern to realize high accuracy speech recognition. 4. The realization of remote video surveillance: using JPEG image coding, the video frame is transmitted from the system server to the client in the form of compressed code stream. The user can monitor the status of the home in real time through network access; at the same time, for the fixed camera, With the same background, background mask is used to provide reliable and accurate support for intrusion detection. 5. The choice of communication mechanism between each function module and embedded microprocessor, and the design of communication program. 6. design and implementation of home system network access site: compared with the client home control platform before the improvement of the system, the system network access platform is authenticated in the user's identity. Home state feedback and home network access security were improved. 7. Analyze the system running test, summarize the advantages and disadvantages of the current system, and introduce the improvement plan of the system.
