Abstract:First of all, the concepts of "industrial Internet" and "energy Internet" are elaborated, the origin, connotation and key technologies of industrial Internet and energy Internet are explained respectively. Then, the research status and development situation of industrial Internet and energy Internet are summarized, and the development level of industrial Internet and energy Internet at home and abroad are compared. Further, the frameworks industrial Internet and energy Internet system are proposed separately, which the core index of industrial Internet and energy Internet is respectively industrial big data and energy big data. Besides, the core technologies of the industrial Internet and the energy Internet are analyzed in detail. In addition to the common concern of communication, control, data analysis and other technologies, the development of the industrial Internet needs the support of industrial software, and the energy Internet should overcome advanced energy storage and intelligent transmission technologies. Finally, the integration of industrial Internet and energy Internet development trend is discussed from the three aspects of multi-level and diversified development of industrial Internet, new technology driven energy Internet high-quality development and industrial Internet and energy Internet in-depth integration development.
