Abstract : With the high integration of information technology and industrial technology, the deep interweaving of communication networks, computer technology, automation technology and software systems has created a new value model. In the field of manufacturing, such resources, information, goods and people are interrelated. Forming a system of virtual and real, the German called it "Industry 4.0." The only way for the Internet to activate traditional industries and maintain the long-term competitiveness of the manufacturing industry: Compared with the previous three industrial revolutions, we believe that the biggest advancement of Industry 4.0 is to use the Internet to activate traditional industrial processes, so that factory equipment can “talk and think†while Achieve three major functions: minimize the dependence of the manufacturing industry on the labor force, minimize the circulation costs, and maximize the individualized needs of users.
In the long run, Industry 4.0 will invest far more than the general industry in smart factories, but the project's profitability will also increase significantly, and the greater the capital investment and the steeper the slope, the higher the marginal return of investment. No matter what kind of economy, Industry 4.0 will be the only way to avoid the development of manufacturing industry, and it is the biggest wave of the world's manufacturing industry in the future. We have always been focusing on the field of industrial control, and at the same time deeply felt the changes brought by this industrial intelligence to manufacturing and production. The Internet of Things has been continuously entering industrial manufacturing. In our cooperative enterprises, industrial production data is real-time. Acquisition (such as MES system) is typical, and in the industrial production information network, ZigBee deserves to be the protagonist.

The MES system is a production information management system for the execution layer of the manufacturing enterprise. It can provide enterprises with manufacturing data management, planning and scheduling management, production scheduling management, inventory management, quality management, tool tooling management, procurement management, and bottom layer. Data integration analysis, upper layer data integration decomposition and other management modules. It is the link of enterprise CIMS information integration, and is the basic technical means to implement the enterprise agile manufacturing strategy and realize the agile production of the workshop. The factory manufacturing execution system MES is a production management technology and real-time information system that has been rapidly developed internationally and facing the shop floor in the past 10 years. MES can provide users with a fast-responding, flexible and refined manufacturing environment to help companies reduce costs, deliver on time, improve product quality and improve service quality. Applicable to different industries (home appliances, automobiles, semiconductors, telecommunications, IT, medicine), it can provide good enterprise information management for single mass production and hybrid manufacturing enterprises with many varieties and small batch production and mass production.

Throughout the system, the ZigBee module can build a variety of network topology structures through a robust network transparent transmission protocol, enabling the entire layout of the entire manufacturing system to be informed and networked, and can be accessed through the gateway to connect to the Ethernet. Intelligent management and mature application in various complex factory environments.

At present, 44% of the major industrial sectors in Germany have adopted the “Industry 4.0†related production and technology models. There are more and more manufacturing companies and factories in the country to enter this direction, which fully shows that Industry 4.0 has changed from a concept to a reality.
