【摘要】：随着物联网应用的增多,应用之间相互独立,数据异构,格式不统一,系统封闭,各自为政,缺乏健全的认证授权机制,物联网系统碎片化严重等问题日益突出。针对以上问题,本文借鉴面向资源体系架构的软件设计理念,构建了基于Web的物联网开放服务模型。将物联网服务的共性需求交由一个通用的物联网开放服务平台完成,为物联网设备接入、数据处理、服务发布、用户管理和应用展现等一系列公共服务提供了快速的框架解决方案,使得系统的资源可以开放共享,同时应用得以快速部署。本文将主要从以下几个方面进行研究:(1)在分析物联网业务需求的基础上,结合现有体系架构和面向资源的软件设计思想(ROA),提出物联网开放服务模型,描述核心服务模块的功能及服务流程。(2)分析设计基于Web的物联网开放服务平台,构建整体服务架构,为了实现对物联网资源的抽象与检索,提出物联网资源模型,通过物联网(Web of Things)中间件屏蔽底层设备的差异,实现设备资源的统一访问。为了促进个性化应用服务的开发,实现了一套RESTful API,让开发者能够方便快捷的开发自己的创意应用,最后以Web方式实现核心服务模块。(3)基于开放API实现智慧服务物联网开放平台,利用应用系统的可视化操作,让用户体验物联网开放模型的整个服务流程,并通过该系统对核心服务模块进行功能性验证。
[Abstract]:With the increase of Internet of things applications are independent of each other heterogeneous data format is not uniform the system is closed each other the lack of a sound authentication and authorization mechanism the Internet of things system fragmentation and other problems are increasingly prominent. In view of the above problems, this paper builds an open service model of the Internet of things based on Web for reference to the concept of software design oriented to resource architecture. The common needs of the Internet of things services will be handed over to a common Internet of things open service platform, for the Internet of things equipment access, data processing, service release, A series of public services, such as user management and application presentation, provide rapid framework solutions that allow open sharing of system resources and rapid deployment of applications. This paper will mainly study the following aspects: (1) based on the analysis of the business requirements of the Internet of things, combined with the existing architecture and resource-oriented software design idea (ROA), an open service model of the Internet of things is proposed. Describe the function and service flow of the core service module. (2) analyze and design the open service platform of the Internet of things based on Web, construct the whole service architecture, in order to achieve the abstraction and retrieval of the Internet of things resources, put forward the model of the Internet of things resources, Through the (Web of Things) middleware of the Internet of things, the differences of the underlying devices are shielded and the unified access to the equipment resources is realized. In order to promote the development of personalized application service, a set of RESTful API is implemented, which enables developers to develop their own creative applications conveniently and quickly. Finally, the core service module is implemented by Web. (3) based on the open API, the intelligent service Internet of things open platform is implemented. Using the visual operation of the application system, the user can experience the whole service flow of the open model of the Internet of things, and verify the function of the core service module through the system.
