摘要
上下文模型是构建基于上下文感知的物联网环境下信息系统智能交互的基础课题之一。在以物物交互普遍存在的物联网环境中,节点及其周围环境的信息是主要的上下文。文章研究了物联网环境下智能交互系统的上下文模型,主要分析了物联网环境下信息系统智能交互中上下文含义、分类和形式化描述,并以智能电网中智能储能设备的即插即用场景对模型进行了验证。
Context in internet of things （IOT） environment with content connected with content refers to information of one node and its surroundings. Context model is one of fundamental research tasks in constructing context-aware information system intelligent interactions in IOT environment. This paper proposes a context model of intelligent interaction system, and then depicts the meaning of context, classification of context and a formal representation of context respectively in detail, Finally, the proposed model is validated by an example of plus-play scenario for smart energy storage device in the smart grid.
