基于Web服务的物联网体系结构模型及应用

摘要

物联网系统将各个传感信息进行有效融合,但由于架构和接口的不同,软硬件平台和通信协议相互独立,使得分布式物联网系统无法统一操作和管理. 针对分布式物联网系统难以实现的问题,提出一种基于Web Service的物联网系统架构模型. 首先对模型所需要的本地传感服务系统、集成传感服务系统和集成应用服务系统进行功能和架构分析;其次介绍Web Service接口的设计;最后将服务及功能进行抽象,规范模型三种服务系统的关系. 案例证明该方案有较好的适用性,灵活性和扩展性.%IoT system effectively integrates veriuos sensing information, however, the distributed IoT system can not be operated and managed in uniform due to the difference in its architecture and interface and the independence each other in its software and hardware platform and its communication protocols.Aiming at the problem which the distributed IoT system is difficult to implement, we propose a Web service-based IoT system architecture model.First, we analyse the functions and architectures of three service systems the model required, they are the local sensing, the integration sensing and the integrated application;Secondly, we introduce the design of Web service interface;Finally, we abstract the services and functions, standardise the relationship between three service systems of the model.Cases prove that the scheme has better applicability, flexibility and extensibility.
