发布时间：2018-07-21 18:48
【摘要】：近年来,随着物联网技术飞速发展,物联网的应用领域越来越广泛,因此需要大量的传感器设备接入物联网中,为物联网应用的开发提供所需资源。物联网网关在实现各类感知层设备无缝接入物联网中时起到了重要的桥梁作用。目前,物联网网关仍然存在着一些问题:传感设备的种类繁多,通信协议各异,导致设备接入物联网的过程复杂。对于物联网应用的开发人员来说,缺乏一个有效的统一的通信协议框架使得感知层设备能够灵活的加入网络。为了解决上述问题,本文在基于开源硬件平台的基础上,设计并实现了物联网网关中间件的即插即用系统方案。本文首先对相关技术进行了深入的研究,主要研究内容包括物联网网关中间件、即插即用、Web of Things(WoT)和开源硬件等应用技术。总结并分析了目前的研究现状和关键技术。然后,本文通过将网关中间件技术与AllJoyn通信协议框架相结合,提出了两层结构的网关架构,并重点研究了网关中间件中的即插即用模块。同时对数据处理模块,设备注册模块,数据上传模块等进行了研究。并结合Web of Things技术,将设备资源开放至WoT平台。之后,本文介绍了系统主要功能模块技术方案与实现细节。最后,本文在实际环境中对系统进行部署,并通过应用案例对系统中设备的即插即用功能进行了验证。
[Abstract]:In recent years, with the rapid development of the Internet of things technology, the application of the Internet of things is becoming more and more extensive. Therefore, a large number of sensor devices are needed to connect to the Internet of things, which provides the necessary resources for the development of Internet of things applications. Internet of things gateways play an important role in realizing seamless access to the Internet of things by various perceptual devices. At present, there are still some problems in the Internet of things gateway: there are many kinds of sensor devices and different communication protocols, which lead to the complexity of the process of accessing the Internet of things. For the developers of the Internet of things, the lack of an effective and uniform communication protocol framework enables the perception layer devices to join the network flexibly. In order to solve the above problems, this paper designs and implements the plug and play system of Internet of things gateway middleware based on open source hardware platform. In this paper, the related technologies are studied, including Internet of things gateway middleware, plug and play Web of things (WoT), open source hardware and other application technologies. The current research situation and key technologies are summarized and analyzed. Then, by combining gateway middleware technology with AllJoyn communication protocol framework, this paper proposes a two-tier gateway architecture, and focuses on the plug and play module in gateway middleware. At the same time, the data processing module, equipment registration module, data upload module were studied. Combined with Web of things technology, the device resources are opened to the WoT platform. After that, this paper introduces the technical scheme and implementation details of the main functional modules of the system. Finally, the system is deployed in a real environment, and the plug and play function of the device in the system is verified by an application case.
