云端融合的工业互联网体系结构及关键技术

The architecture and key technologies for an industrial Internet with synergy between the cloud and clients

随着物联网、云计算和大数据等技术的发展,人类正迈入第四次工业革命时代.工业互联网作为建立在生产对象之间、对象与外部环境之间、对象与人之间高度协同、共享智能的全球性网络,是实现这场革命的核心.然而目前对工业互联网的研究大多局限在物联网、云计算和大数据等各自辖域,其云端协同尚处于"感、联、知、控"的初级阶段,尤其缺乏云端融合、共享智能的体系结构及关键技术,无法应对其中感知对象更加复杂、联网实体更加多元、数据处理更加快速、反馈控制更加智能等需求.为此,本文首先重点调研和归纳了该研究领域所涉及的几个重要方向的研究现状和面临挑战;在此基础上,提出一个云端融合的工业互联网新型体系结构及相关关键技术的解决方案;之后,针对智能制造领域的具体应用场景,将所提相关技术进行应用;最后,总结全文并展望了云端融合的工业互联网未来发展趋势.

The fourth industrial revolution has been unveiled with the rapid development of Internet of things(IoT), cloud computing, and big data. The industrial Internet, as a highly cooperative and intelligence-sharing global network that connects entities, human beings, and the environment in smart manufacturing, is the core of this revolution. However, most current research on the industrial Internet is restricted to IoT, cloud computing, or big data, respectively. The synergy between the cloud and clients is currently at a very primary stage of sensing,connection, and knowledge, lacking a cloud-client-integrative architecture and key technologies that could meet the evolving requirements of networked smart production, including more complex objects to be sensed, more diversification of entities to be connected, faster data processing, and more intelligent feedback control. This paper first surveys some important research directions with respect to this research field and summarizes the research status and challenges. On this basis, a novel cloud-client integrative industrial Internet architecture and solutions for related key technologies are proposed. Then, the proposed technologies are demonstrated for some specific applications in the field of intelligent manufacturing. Finally, the prospects for cloud-client-integrative industrial Internet research are discussed and concluded.
