As a new generation of mobile communication technology, 5G technology meets the needs of traditional manufacturing enterprise intelligent manufacturing transformation for wireless network applications, and can meet the needs of equipment interconnection and remote interactive applications in industrial environments. In industrial applications such as Internet of Things, industrial automation control, logistics tracking, industrial AR, and cloud robots, 5G technology plays a supporting role.
Intelligent factories in 5G era will greatly improve labor conditions, reduce manual interference in production lines, and improve the controllability of production process. The most important thing is to use information technology to connect all processes of enterprises, realize the interconnection of all links from design, production to sales, and realize the integration and optimization of resources on this basis.
5G Technology Scenario Supporting Intelligent Manufacturing
In industrial applications such as Internet of Things, industrial automation control, logistics tracking, industrial AR, and cloud robots, 5G technology plays a supporting role.
Internet of Things: With the advancement of the intelligent transformation of the factory, the Internet of Things as a key supporting technology for connecting people, machines and equipment is receiving high attention from enterprises. This demand has greatly stimulated the development of 5G technology while pushing the application of IoT applications.
Industrial Automation Control: This is the most basic application in a manufacturing plant, and the core is a closed-loop control system. The 5G provides a very low-end, high-reliability, massively connected network, making closed-loop control applications possible via wireless network connections.
Logistics tracking: From warehouse management to logistics and distribution, it requires extensive coverage, deep coverage, low power consumption, large connections, and low-cost connection technology. In addition, the end-to-end integration of virtual factories spans the entire lifecycle of a product, connecting a wide range of sold merchandise, as well as low-power, low-cost and wide-coverage networks, horizontal integration within or between enterprises. There is also a need for ubiquitous networks, and 5G networks are well suited to meet these needs.
Industrial AR: In the process of intelligent factory production, people play a more important role. Because of the high flexibility and versatility of future factories, there are higher requirements for workshop staff. Augmented reality AR (AR) will play a key role in rapidly meeting the needs of new tasks and production activities. AR can be used in the following scenarios in the intelligent manufacturing process:
Such as: monitoring process and production process. Step-by-step production task guidance, such as manual assembly process guidance; remote expert business support, such as remote maintenance. In these applications, auxiliary AR facilities need to be flexible and portable to the greatest extent in order to carry out maintenance work efficiently.
Cloud-based robots: In intelligent manufacturing production scenarios, robots need self-organizing and synergistic capabilities to meet flexible production, which brings the need for robots to cloud. The 5G network is the ideal communication network for cloud-based robots and the key to enabling cloud-based robots.
5G technology has become the key enabling technology to support the transformation of intelligent manufacturing. It can connect the widely distributed and scattered people, machines and equipment to build a unified Internet. The development of 5G technology can help manufacturing enterprises get rid of the chaotic application state of wireless network technology in the past, which has a positive significance for promoting the implementation of industrial Internet and deepening the transformation of intelligent manufacturing.
The Core of Intelligent Manufacturing is Intelligent Factory
With the intensification of the information revolution, manufacturing elements such as machinery, equipment, people and products are no longer independent individuals. They are closely linked through the industrial Internet of Things to achieve a more coordinated and efficient manufacturing system.
The current transformation of manufacturing can be seen as the integration of automation upgrades and information technology. This is not just automation and machine substitution, but also the factory can make independent decisions, flexibly produce diversified products, and quickly respond to more. Market changes.
The combination of artificial intelligence and manufacturing systems will be inevitable. Using algorithmic models such as machine learning, pattern recognition, and cognitive analysis, the ability of the plant control management system can be enhanced to achieve so-called intelligent manufacturing, in order to enable enterprises to compete in today's competitive environment. Get a better edge.
The intelligent manufacturing process is mainly around smart factories, and artificial intelligence plays an important role in smart factories. The Internet of Things connects all the machines and devices together, such as the controller, sensors, and actuators. Then, the AI can analyze the data uploaded by the sensors, which is the core of intelligent manufacturing.
With the development of the application of industrial Internet of Things, the network and the physical system will be closely linked, that is, the Internet of Things will connect the processors and sensors at the production site, so that the robots can communicate with each other, and the machines and people can communicate with each other. The work will no longer be strictly divided, and the future manufacturing system will bring people and machines together.
Digital twins are an important role. The entire process of intelligent manufacturing has a digital twin model. The system includes anything in the real world, which can be an application or an operation guide.
In addition, there is human-computer interaction in the intelligent manufacturing system, that is, the interaction between people and robots. There are also artificial intelligence to drive, optimize products and processes. Factories need to do some predictive maintenance or predict the energy consumption of the machine, etc. More and more of these functions can be implemented in smart factories.
Prospect of Intelligent Factory in 5G Era
From 2016 to 2018, China's 5G basic R&D test is divided into three phases. The first phase is the 5G correlation technology test, the second phase is the 5G technology solution verification, and the third phase is the 5G system verification.
Faced with the third stage of the experiment, in order to further enrich the scene, China has carried out experiments in several cities, including the combination of 5G technology and the core planning of smart cities to help the construction of smart cities; the promotion of double-innovation by 5G experiment; and the full use of 5G technology in industrial Internet and intelligent manufacturing.
Intelligent factory is one of the important application scenarios of 5G technology. The 5G network is used to seamlessly connect the production equipment, and further connect the design, procurement, warehousing, logistics and other links, so as to make the production more flat, customized and intelligent, so as to construct a future-oriented intelligent manufacturing network.
