The "Industry 4.0" strategy was officially launched by the German government at the Hannover Messe in April 20 13. The research project is jointly funded by the German Federal Ministry of Education and Research and the Federal Ministry of Economy and Technology. Its original purpose was to improve the competitiveness of German industry and take the lead in the new round of industrial revolution. "Industry 4.0" is the fourth industrial revolution led by intelligent manufacturing. This strategy aims to make the manufacturing industry intelligent by making full use of the combination of information and communication technology and cyberspace virtual system-cyberspace physical system.

Now, as the extension and expansion of the Internet, with the wide application of sensors, identification technology, network controller and 3D printing technology, Industry 4.0 has actually come to us. The Internet has brought us faster communication speed, more flexible processing methods, more available data and more powerful computing power. Driven by Industry 4.0, the industry also tends to be more intelligent and Internet-based. In fact, under the environment of Industry 4.0, the informatization level of industrial enterprises is getting higher and higher, and the amount of information data is also increasing, and the requirements for information processing are also improved due to the massive data generated by various equipment and instruments. It is very useful for the development of Industry 4.0 to build a big data platform in the industrial environment, process the massive information collected in time, and increase the computing power and data digestion capacity of the information system. Moreover, the place where big data can best meet the needs of Industry 4.0 is not only its "big", but also its integration, analysis and utilization of data. This is the real intelligent direction of Industry 4.0.
