Abstract Proposed a cyber-physical space integrated context model and infrastructure, named ScudContext, which utilizes semantic technology to describe context, models the physical space with a corresponding spacetree in cyber space, and manages context service according to SOA (service oriented architecture) standards. ScudContext was applied to a simulation system for building monitoring. The results of functional experiment and performance experiment show that ScudContext has obvious advantages such as loosely coupled, easily collaboration, scalability, standardization of interfaces, and can reflect the evolution of physical space well.

ScudContext:信息-物理空间融合的大规模 环境上下文服务
提出一种信息-物理空间对应的上下文模型及相应上下文基础设施ScudContext.ScudContext通过语义技术描述上下文;通过构建空间树建立信息空间与物理空间的对应关系,将SOA(service oriented architecture)标准用于组织、管理和提供各类上下文服务.ScudContext被应用于办公楼宇监控的仿真系统,从功能和性能实验结果看,ScudContext具有松耦合、易协同、可扩展、接口标准化等优点,能很好地反映物理空间上下文的演化情况.
