摘要
传感网服务整合架构中的服务层和传感器层存在"互操作鸿沟",即服务层和传感器层的适配工作代价非常大,现有的人工适配的方法严重影响观测的实时性,形成了传感器"即插即用"的巨大障碍。设计了一种传感器的信息模型USDI用于描述传感器的数据模型和协议模型,进而基于USDI提出了一种动态适配器方法,通过自动生成动态适配来实现与传感器的自动适配,进而实现传感器的"即插即用"。相关实验表明:该方法能够在不明显增加时间消耗的前提下,将适配的人工干预降低为零,进而能够实现传感器数据的自动解析,为传感器的"即插即用"提供了标准方法。
It is found that there is an interoperability gap between sensor layer and upper service layer constructed by sensor web enablement,which takes extraordinary large cost to make adaption manually between sensor layer and service layer,and it also seriously affects real-time observation,forming a huge obstacle to enable sensor plugand-play.An information model which is called USDI is designed to describe data model and protocol model of sensors,and based on USDI,a method of dynamic adapter is proposed,by generating adaptor automatically to realize automatical adaptation with sensor,and enable sensor plug-and-play.Related experiments prove that this method can adapt sensor datas without human intervention,furthermore realize automatic parsing of sensor data and provide standard method for sensor plug-and-play.
