传感器语义处理中面向数据的工作流设计

Data-oriented Workflow Design in Sensor Semantic Process

为了实现Web中不同传感器系统之间的数据共享和互操作,在结合语义传感器Web(Semantic Sensor Web)概念的基础上,以建筑结构安全监测的传感器及感测数据为例设计了语义模型.同时,为了使得Web中各系统可以自动进行传感器的语义处理,提出面向数据的工作流处理方法,分析了该技术的特点和与传统工作流技术的区别,在该方法中以数据驱动处理,通过传感器数据的自动识别调用相应的处理模块,可以实现感测数据的自动提取、自动标注等处理方法,从而形成Web中有特定含义的传感器语义数据.最后以建筑结构安全监测系统中工作流的设计为例说明了该技术的具体应用.

In order to realize the data sharing and interoperability between different sensor system on the Web,combining with the con- cept of Semantic Web Sensor, the semantic models are designed for sensor and its data which are used for monitoring the safety of the building structure. Meanwhile, the data-oriented work.flow for sensor data semantic process is proposed to annotate sensor data seman- tics automatically, and the difference between data-oriented workflow and traditional workflow is analyzed. In this data-oriented work- flow ,the professional processing model is used after data automatic identification. So the processing method of automatic extraction and the automatic label for the data are realized. At last, an application case is given by putting this workflow in a monitoring system for the safety of building structure.
