【摘要】：物联网技术在现代智能家居系统中的应用不断成熟,对比现有智能家居系统在家庭内网的网络访问局限性,我们设计并改进了一种基于物联网的全网络化智能家居系统。从智能家居的系统需求出发,文章介绍系统的功能模块定制,网络控制系统的选择与设计,基于功能需求的软硬件设备定制开发,以及系统实现的优越性对比分析；着重介绍智能家居的网络控制系统、智能网关架构、数据库访问技术在人机交互的应用以及音视频处理的应用,重视智能网关访问安全性。经过对系统集成测试分析,该系统能够满足人们对现代智能家居系统易用性、可用性以及便利性的需求。本文的主要工作： 1.智能家居系统的整体硬件平台搭建：根据人们对于家居系统在安防监控、家电操作、照明管控、远程能源付费、远程网络监督以及智能语音交互等方面的功能需求,定制完成各传感单元、互联网络以及家居网络控制平台的铺设与安装。 2.家居网络控制系统架构的选择：通过分析对比各系统架构优劣,确定本系统网络控制架构的选择。 3.智能语音识别的实现：采用微软语音识别开发包speech SDK5.1,根据命令识别模式,定制语音识别字典,实现高准确度语音识别。 4.远程视频监控的实现：采用JPEG图像编码,将视频帧以压缩码流的形式由系统服务器传输至客户端,用户可通过网络访问来实时监控家居状态；同时对于固定摄像头,拍摄背景相同,应用背景掩膜,为入侵检测提供可靠且准确的辅助。 5.各功能模块与嵌入式微处理器的通信机制选择,以及通信程序设计。 6.家居系统网络访问站点的设计与实现：与本系统改进前的客户端家居控制平台形成对比,系统网络访问平台在用户身份验证、家居状态反馈和家居网络访问安全等方面进行了改进。 7.系统运行测试分析,总结目前的系统优缺点,介绍系统的改进计划。
[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.
