物联网的快速发展促进了人类对真实世界的智能化认识,利用各类传感装置使得人-物-世界实现互联。基于Web的应用服务使用提升了对各个领域物联网应用范围的扩展。本文提出了一个基于物联网平台的应急消防管理系统,利用对真实世界的物理对象进行整合形成相应的用于可管理的虚拟对象(Virtual Objects,VO),并形成相互关联的上下文语义本体模型。使用语义本体的魅力在于它允许信息可重用性、可扩展性和互操作性,它使VO维护编排、联合、协作和协调,本文所设计的系统是具备上下文意识,通过分布式传感器和接收上下文环境信息检测紧急情况,处理火灾紧急状态,并通过决策支持模式采取火灾事件日志为消防管理对象提供准确的应急信息。
The rapid development of the Internet of Things has promoted human’s intelligent understanding of the real world and utilized various sensing devices to make the human-object-world interconnected. The use of Web-based application services enhances the expansion of the Internet of Things application in various fields. In this paper, an emergency fire management system based on the Internet of Things platform is proposed. Virtual physical objects (VOs) are formed by integrating real-world physical objects and form inter-related contextual semantic ontology models. The attractiveness of using the semantic ontology lies in the fact that it allows the reusability, scalability and interoperability of information. It enables the VOD maintenance to be arranged, federated, coordinated and coordinated. The system designed in this paper is context-aware. Through the distributed sensor and the receiving context Environmental Information Detects an emergency, deals with a fire emergency, and uses a fire event log to provide firefighting managers with accurate emergency information through a decision support model.
