【摘要】：随着生活水平的不断提高,人们不断地对居住环境提出更高的要求,越来越注重家庭生活中每个成员的舒适、安全与便利,智能家居随着此需求应运而生,与此同时,以智能手机、平板电脑为代表的移动互联网终端越来越普及。在此背景下,一种可利用移动互联网终端随时随地获取家庭环境信息、智能控制家电、实施家庭视频监控的新型智能家居系统必将具有无比广阔的市场空间。本文面向此需求,基于SEP611平台设计并实现了一套完整的新型智能家居控制系统。该系统由智能控制终端、P2P平台、智能家居网关、视频采集服务器、无线遥控开关构成,其中智能控制终端为基于Android平台的移动互联网终端,其上运行了本课题所开发的控制端软件。智能家居网关可通过红外收发模块与红外家电建立通信,也可通过射频433MHz(Radio Frequency 433,RF433)收发模块与RF433家电建立通信,并内置温湿度传感器获取室内温湿度信息；智能家居网关和视频采集服务器通过Wi-Fi接入互联网并连接P2P平台；智能控制终端通过Wi-Fi/4G/3G/2G接入互联网并通过P2P平台连接智能家居网关实施远程家电控制及家庭温湿度监测,连接视频采集服务器实施家庭视频监控。针对众多红外、RF433家电,本文通过遥控器解码学习,将遥控器码值映射到智能控制终端,实现家电控制。针对家庭视频监控流畅性的要求,本文采用H.264编解码方案,通过智能家居网关的硬件编码及智能控制终端的软件解码实现。经测试本系统能稳定的实现家电控制,准确的实现温湿度监测,流畅的显示家庭视频监控图像,分辨率为320×240,帧率为15帧／秒。该系统将改变智能家居系统传统单一的控制方式,实现智能家居控制方式向移动互联网方向发展。
[Abstract]:With the continuous improvement of living standards, people constantly put forward higher requirements for the living environment, and pay more and more attention to the comfort, safety and convenience of each member of family life. With this demand, smart home emerges as the times require, at the same time, Mobile Internet terminals represented by smart phones and tablets are becoming more and more popular. Under this background, a new type of smart home system, which can obtain home environment information at any time and anywhere by using mobile Internet terminal, intelligently controls household appliances and implements home video surveillance, will have an incomparably broad market space. In this paper, a new intelligent home control system based on SEP611 platform is designed and implemented. The system is composed of intelligent control terminal, P2P platform, smart home gateway, video acquisition server and wireless remote control switch. The intelligent control terminal is a mobile Internet terminal based on Android platform. The control software developed by this subject is run on it. Smart home gateway can establish communication with infrared home appliances through infrared transceiver module, and establish communication with RF433 home appliances through RF 433MHz (Radio Frequency 433F433) transceiver module, and acquire indoor temperature and humidity information by built-in temperature and humidity sensor. The intelligent home gateway and video acquisition server connect to the Internet through Wi-Fi and connect to the P2P platform; the intelligent control terminal connects to the Internet through Wi-Fi/4G/3G/2G and connects the smart home gateway through the P2P platform to implement remote home appliance control and home temperature and humidity monitoring. Connect video capture server to implement home video surveillance. Aiming at many infrared and RF433 household appliances, the remote control code value is mapped to the intelligent control terminal to realize the home appliance control by decoding the remote controller in this paper. In order to meet the requirement of home video surveillance fluency, this paper adopts H.264 codec scheme, through the smart home gateway hardware coding and intelligent control terminal software decoding implementation. After testing, the system can realize home appliance control stably, realize temperature and humidity monitoring accurately, display home video surveillance image smoothly, the resolution is 320 脳 240, frame rate is 15 frames / s. The system will change the traditional single control mode of smart home system and realize the development of smart home control mode towards mobile Internet.
