面向工业应用的车间上下文感知计算模型研究

Research on Industrial Application Oriented Workshop Context-Aware Computing Model

针对可穿戴计算技术在制造业设备装配和维护应用领域辅助用户作业的应用中,车间内设备、人员和环境等上下文感知的需求,设计了车间上下文感知计算模型。运用无线传感网络、可穿戴计算机等构建上下文采集基础设施,利用OWL表示上下文和描述上下文服务,通过基于语义的上下文服务提供请求和应答、发布和订阅两种统一的上下文访问接口,以便快速开发上下文感知应用;最后给出了应用实例及分析。

Task operation assisted by wearable computer is a challenging and hot topic in domains for equipment assembly and maintenance. Efficient context-awareness of equipment, personnel and environmental in the workshop is important to design wearable computing application. A workshop context-aware computing model which combines wireless sensor network and wearable computer is presented to build context infrastructure. Context presentation and context service depiction method based on web ontology language is discussed. An application example is discussed.
