4、构设备间的无缝互联以及自发交互， 是当前急需解决的热点问题。这个问题的解决将给物联网交互模型提供好的解决方案， 并且将给人们未来的生活提供一个便捷、 安全、 智能的居住环境。 针对家庭物联网中异构设备互联互通的研究和应用， 目前也有不少的方法和建议， 并且实现了一些相关功能， 如远程监控等。 但都或多或少的存在一些问题。首先，由于各方利益的博弈，要让设备制造商们统一通信协议几乎是不可能的；其次， 采用同一通信协议的家电设备也无法和家庭环境中的传感器节点间进行顺畅的通信和良好的交互；最后，智能家居控制终端的移动性和个性化都比较差。基于移动平台的控制终端较少， 并且无法实现根据不同户型和家居布置生
5、成个性化的控制界面，用户体验较差。 针对以上问题，本文提出了基于普适计算的泛在设备互联架构。该框架主要实现以下三大功能： 1. 异构设备互联互通。通过一个多模融合网关将家居环境中使用不同通信协议的传感器设备、家电设备以及网络设备汇聚在一起，然后利用 UPnP 协议对设备进行虚拟化， 将这些设备转换成具有统一标准的网络服务，从而实现异构设备之间的互联互通。 2. 设备间协同交互。通过建立协同交互模型，利用情境感知技术并建立初级的决策推理机， 该推理机主要基于专家知识和用户习惯，使得设备之间可以自发的交互、共享资源，从而提高整个家居环境的智能化程度。 3. Android 平台控制端。基于 And
6、roid 移动平台，设计并实现了一个家居布局生成工具和一款适应于家庭物联网的，集家电控制、视频监控和情境设置等功能于一体的移动应用。 该应用可以在局域网和广域网两种环境下对设备进行远程监控，并且拥有方便、现实感强的操作界面。 关键词：关键词：家庭物联网、设备虚拟化、情境感知、UPnP、Android II Abstract With the vigorous development of computer and network communication technology, and constantly improve the level of the manufacturing pro
