【摘要】：随着电子信息技术的发展与互联网的普及,世界进入了崭新的物联网时代。智能家居作为物联网领域重要的发展方向之一,正在逐步改变人们的生活方式。然而,多种产品技术标准互不兼容,造成智能家居普及率不高的不利局面。因此,Allseen联盟推出AllJoyn技术以建立物联网统一标准。AllJoyn技术是一种中性平台系统,它可以将多种平台连接,简化多种技术标准的设备之间的通信过程。本文基于AllJoyn技术的多平台兼容优势,设计了一种智能家居控制系统。在研究了AllJoyn技术核心总线机制与系统结构的基础上,确定系统总体方案,功能为家庭内部烟雾、温湿度和光照物理量的采集,在Yeelink平台实现数据显示与家庭环境控制。系统实现包括硬件设计和软件设计两部分。系统硬件部分主要设计了信息采集节点系统,节点主控制板选择Arduino Due单片机,在主控制板上接入DHT11温湿度传感器、MQ-2烟雾传感器以及BH1750光照传感器,使用以太网扩展板连接信息采集节点到网络。系统软件设计分为三个部分:第一,在PC上编写AllJoyn服务端程序,生成AllJoyn总线,实现客户端数据接收,完成Yeelink平台上数据消息和开关信号的传送;第二,移植AllJoyn客户端项目,设计Arduino客户端与服务端通信和节点信息采集程序;第三,设置Yeelink平台,编辑传感器节点的触发动作条件,添加相应控制开关,实现控制指令的发送。经过模拟家庭室内环境的测试,本系统服务端可以通过AllJoyn总线准确地发送Arduino客户端的数据,在Yeelink平台的Web界面以及手机APP界面可以显示数据曲线,并且在满足设定条件时可执行相应的动作并推送手机消息。测试结果表明,系统实现了预期的功能,具有较好的稳定性。
[Abstract]:With the development of electronic information technology and the popularity of the Internet, the world has entered a new era of the Internet of things. Smart home as an important development direction in the field of Internet of things. Gradually changing people's way of life. However, a variety of products and technology standards are incompatible, resulting in a low penetration of smart home situation. Allseen Alliance launched AllJoyn technology to establish a unified standard for the Internet of things. AllJoyn technology is a neutral platform system that can connect multiple platforms. This paper is based on the advantages of multi-platform compatibility of AllJoyn technology. A kind of intelligent home control system is designed. Based on the study of the core bus mechanism and system structure of AllJoyn technology, the overall scheme of the system is determined, the function of which is the smoke inside the home. Collection of physical quantities of temperature, humidity and light. Data display and home environment control are realized on Yeelink platform. The system implementation includes two parts: hardware design and software design. The hardware part of the system mainly designs the information acquisition node system. The node main control board selects Arduino Due single chip microcomputer, and connects the DHT11 temperature and humidity sensor, MQ-2 smoke sensor and BH1750 illumination sensor to the main control board. The system software design is divided into three parts: first, write AllJoyn server program on PC to generate AllJoyn bus. Realize the client data receiving, complete the data message and switch signal transmission on the Yeelink platform; Second, transplant AllJoyn client project, design Arduino client and server communication and node information collection program; Third, set up the Yeelink platform, edit the trigger action condition of sensor node, add the corresponding control switch, realize the sending of the control instruction, and pass the test of simulating the indoor environment of the home. The system server can send the data of Arduino client accurately through AllJoyn bus. The data curve can be displayed in the Web interface of the Yeelink platform and the APP interface of the mobile phone, and the corresponding actions can be performed and the mobile phone message can be pushed when the set conditions are satisfied. The test results show that. The system achieves the expected function and has good stability.
