摘　　要：物联网(Internet of Things,IOT)是互联网的拓展,是将各种传感设备与互联网结合起来,实现物与物、物与人之间的信息互联与共享。但是在大型的物联网系统中,存在多种异构的设备,它们间信息的交互是我们面临的主要挑战。针对此问题,提出一种基于语义的物联网中间件模型,将语义技术引入物联网中间件中,利用不同的设备发现模块查找不同类型的设备,然后,根据设备的功能描述创建其OWL-S语义服务描述,添加到服务层,成为服务组合单元,形成语义服务中间件。系统根据用户请求,对所能提供的服务进行服务组合,完成用户提出的需求。在普适计算环境中,用户能透明地创建并执行由多种异构设备组成的复杂任务。为论证此方法的可行性,部署了一个简单的实验系统,予以实现。Internet of things is the extension of Internet, which combines various sense devices and lnternet to realize the interconnec tion and sharing between things or things and human beings. However, in large Interact of things systems, the major challenge we are tacing is the information exchange between heterogeneous devices. Aiming at this problem, a middleware model based on semantic is put forward, which introducing semantic technology into devices internet of things middleware, using different device discovery module search different types of devices. Then, create the OWLs semantic service description according to function description of device, adding to the service layer and becoming a service composition unit, all these form a semantic services middleware. System composites some of services to finish user request. In the pervasive computing environment, users can establish and execute complex task involving muhiple heterogeneous devices. A simple experimental system is constructed to demonstrate its teasibility.
