Abstract: The Industrial Internet has become the main method to promote the integration of industrial and information in China.It deeply integrates the next generation of information technology and advanced manufacturing technology and manufacturing industry,which is an important basis for the construction of strong manufacturing and network country.Currently,China has vigorously promoted the Industrial Internet,and overall the progress is fast.However,there are still some difficulties when promoting the transformation and upgrading of discrete manufacturing industry.The breadth of the Internet of Things(IoT),the depth of applications,and the value mining of industrial data are still to be strengthened.With regard to this,the origin and status of the Industrial Internet was analyzed firstly,and a reference model was constructed for the transformation and upgrading of discrete manufacturing driven by Industrial Internet.Afterwards,three development stages of Industrial Internet was put forward,which including industrial Internet of Things(IoT),industrial Internet of business and industrial Internet of minds.The technical architecture and application challenges were also illustrated in detail to expect to provide theoretical guidance for the promotion of transformation and upgrading of discrete manufacturing industry based on industrial Internet.

Key words: industrial Internet, discrete manufacturing, transformation and upgrading of manufacturing industry, intelligent manufacturing, integration of industrial and information

摘要： 工业互联网作为新一代信息技术与制造业深度融合的产物,已成为当前我国推进工业化和信息化融合的主要手段,也是推进制造强国和网络强国建设的重要基础。目前,我国工业互联网在总体上发展迅速,但在推进离散制造业转型升级的落地应用过程中仍然存在一些难点问题,在物联的广度、应用的深度和数据的价值利用等方面还有待加强。为此,首先梳理和分析了工业互联网的起源、国内外发展现状等,在此基础上构建了工业互联网推动离散制造业转型升级的三维参考模型,提出了工业互联网推动离散制造业转型升级的工业物联网—工业务联网—工业智联网3个发展阶段,并详细阐述了对应的技术体系及面临的挑战,从而为工业互联网推动离散制造业转型升级提供理论上的指导。
