What is Industry 4.0 and what are the core technologies that need to be used?

Industry 4.0 is a division based on different stages of industrial development. According to the current *** knowledge, industry 1.0 is the age of the steam engine, industry 2.0 is the age of electrification, industry 3.0 is the age of information technology, industry 4.0 is the use of information technology to promote industrial change, that is, the age of intelligence. Core technologies that need to be used:

1, information physical systems (CPS)?CPS form networks through (wireless) sensing and driving, able to respond to changing environments, and even predict changes in physical system processes.

2, Cloud computing: cloud computing makes it possible to connect applications or services stored locally to the Internet of Things.

3, big data analytics: big data are data sets that are too large for typical database software tools to collect, store, manage and analyze. Big data analytics methods make industrial intelligence possible, such as machine learning.

4, (IT) system security: data, its dissemination, and all other industrial systems, machines, equipment and originals need to be adequately protected from cyber-attacks.

5, Additive Manufacturing / 3D Printing: Additive Manufacturing (Additive Manufacturing, AM) technology is the use of materials gradually additive method of manufacturing solid parts of technology, as opposed to the traditional material removal - cutting processing technology, is a "bottom-up It is a "bottom-up" manufacturing method compared to the traditional material removal-cutting technology.

6. Augmented Reality (AR): Workers using Augmented Reality glasses can receive instructions remotely to correctly assemble parts or assist in debugging.
