【摘要】：随着科技水平的不断提高,人们对生活工作质量的要求也越来越高,更方便更安全的生活方式将成为发展的主流,智能家居应运而生。由于智能家居的市场广泛、前景光明,因此很多厂商加入到智能家居的研究当中。智能家居包括的内容很多,像是对家居设备的控制以及对家居环境进行监控等等。在无线技术快速发展下,ZigBee、蓝牙等无线通信模块广泛应用于智能家居系统中。本文以ZigBee模块、蓝牙模块和USB摄像头为终端设备,采集相关的家居信息,以ARM处理器为核心,分析处理采集到的数据信息,保存到SQLServer数据库中,在网站中显示家居信息,也可以点击相关设备的控制按钮,通过ARM处理器将相关控制命令发送给相应的设备进行控制,并且USB摄像头可以采集视频数据,在网站中实时显示出来。本系统通过构建ZigBee和蓝牙的异构网络实现完整的智能家居系统。ZigBee终端节点采集数据传递给ZigBee协调器,蓝牙设备也采集相关数据,通过设计出异构网络数据帧,将ZigBee协调器和蓝牙设备采集到的信息封装成相应的数据帧格式,然后通过串口传给ARM处理器,ARM处理器根据数据帧标识判断是哪种设备采集的数据,之后分析数据的合理性将其保存到对应的数据表中;本系统移植了 unixODBC和FreeTDS,使得能够在Linux下访问Windows主机上的SQLServer数据库,同时利用ASP.NET平台下的C#语言完成网站的设计;在视频监控中,使用了 V4L2和Epoll机制完成视频数据采集,移植X264库完成视频数据编码,移植oRTP库完成视频数据传输,最后在浏览器中内嵌VLC播放器的ActiveX插件实现了视频数据的接收显示。在本文最后测试了相关功能,验证了本文提出的方案的可行性。
[Abstract]:With the continuous improvement of science and technology, people have higher and higher demands on the quality of life and work. A more convenient and safer way of life will become the mainstream of development. Smart home emerges as the times require. Due to the wide market of smart home, there is a bright future. Therefore, many manufacturers have joined the research on smart home. Smart home includes a lot of content. Such as home equipment control and home environment monitoring and so on. In the rapid development of wireless technology ZigBeeBluetooth and other wireless communication modules are widely used in smart home systems. Bluetooth module and USB camera as terminal equipment, collect related home information, take ARM processor as the core, analyze and process the collected data information, save it in SQLServer database, display home information in the website, You can also click on the control button of the related device, send the related control command to the corresponding device through the ARM processor, and the USB camera can collect video data. This system realizes the complete intelligent home system. ZigBee terminal node gathers the data to the ZigBee coordinator by constructing the heterogeneous network of ZigBee and Bluetooth. The Bluetooth equipment also collects the related data. By designing heterogeneous network data frames, the information collected by ZigBee coordinator and Bluetooth device is encapsulated into corresponding data frame format, and then passed to ARM processor through serial port to determine which kind of data is collected by arm processor according to data frame identification. The system transplanted unixODBC and FreeTDS to access the SQLServer database on the Windows host under Linux, and completed the design of the website by using the C # language under the ASP.NET platform, after analyzing the reasonableness of the data to be saved to the corresponding data table. In video surveillance, V4L2 and Epoll are used to complete video data acquisition, X264 library is transplanted to complete video data coding, and oRTP library is used to complete video data transmission. Finally, the ActiveX plug-in with VLC player embedded in the browser realizes the receiving and displaying of video data. At the end of this paper, the related functions are tested, and the feasibility of the proposed scheme is verified.
