How will 5G, change manufacturing?

2020-07-07

On June 6, the Ministry of Industry and Information Technology officially issued 5 G of commercial license plates, China’s five-track starter gun officially launched

 

However, it would be too narrow to think of it only as “getting online faster” . Taken together, 5g has three distinct features:

 

  1. With the natural advantages of high frequency band, Antenna Matrix and beam shaping technology, 5g network’s transmission rate can reach 10 GBPS, 10 times higher than 4G network. The experiment of China Unicom’s first 5G base station in Guizhou shows that 5G can reach the download rate of 1.8 gbps under the practical environment. In short, “5G fast, telephone fees can not keep up. “.

 

  1. Super Capacity “4g changes life, 5G Changes Society” . 5G’s ability to transform society is due in no small part to its huge capacity. According to the draft 5G standard issued by the International Telecommunication Union (Itu) , the 5G link density will reach one million devices per square kilometer. This means that the Internet of everything is possible, and a lot of things will be connected to the 5G network to build a real internet of things.

 

  1. Ultra-low delay time, that is, the information from the source host to the server, and then return to the source host required time. In an ideal world, 5g would have a maximum latency of 4ms, which would be Hopps’s advantage over lightning in Zootopia, compared to the 100ms mark in the 4G era.

 

Extremely low latency will lead us to a new era of real time, where technologies such as remote surgery and autopilot will make more practical possibilities for the machine tool industry, this means that systems such as industrial robots can have faster response times.

As 5g becomes more widely available, your robot will have the flexibility to move around and perform more difficult tasks. As humans lose their power and precision, the flexibility of our arms may also be eclipsed by robots.

 

 Hardware ——” cable missing in the factory “

Don’t panic, the missing cable is not stolen. Based on the characteristics of high speed, high reliability and low delay of 5 G technology, the factory no longer needs complex cable for data transmission, each system can directly carry out wireless transmission, wireless control. After the cable disappears, its purchase and maintenance costs will be saved, and the safety risks caused by the cable will be greatly reduced.

 

 

Flexible manufacturing ——” your robot will Walk “

With the disappearance of the cables, the “ropes” that control the robot’s movement disappear, and the robot can move around the factory with wheels (or other devices) at will, which will bring a lot of imagination to the factory’s production mode. At the moment of emphasizing “flexible manufacturing” more and more, a flexible production line that can flexibly adjust the position of each equipment and flexibly assign tasks will become a new artifact of the producer.

 

 

At the same time, in large-scale factories, due to the different QOS requirements for different production scenarios, the high-precision links require lower network delay, and the 5G network with its end-to-end slicing technology has different QoS in the same core network, flexible adjustment on demand can meet the network requirements of different situations, which creates a convenient network space for flexible manufacturing.

 

Information Network ——” Don’t Talk to Party A “

This is not to make the factory ignore the requirements of Party A. In reality, information communication between consumers and producers is an important factor affecting production quality, and production efficiency is often delayed due to communication. But in the 5G era, because of the high coverage of information network, the exchange of information between human and machine will be more extensive. If party a can’t tell you what they want, let him tell the robot. In the 5G era, through computers and even cell phones, party a can connect directly to the production network and adjust accordingly, do what you think is right.

 

maintenance mode ——” maintenance personnel can not come today “

In this day and age, it’s the opening line of a nightmare: every minute of shut down on the production line is a moment of money. But in the 5G era, it will be a new normal —— so don’t be nervous, it’s not that maintenance can’t get to the site, it’s that maintenance won’t.

As more equipment and components are connected to the 5G network, repairmen (even foreign experts from across the continent) can access the 5G network for first-time fault information and use technologies such as VR to direct factories to deal with the problem in real time, more and more problems can be solved online. Behind the efficient troubleshooting, maintenance personnel do not have to do “a thousand miles a day, a thousand miles a night” of the horse.

 

 Intelligent ——” cloud server seems to be in my home “

Into the era of the Internet of everything, each device can be directly connected to the cloud server and communicate with it efficiently with ultra-low delay, a huge amount of information will enter the cloud server network, and constantly “feed” artificial intelligence. This means that the efficiency of cloud server applications and the progress of artificial intelligence learning will be greatly improved, and a huge amount of industrial data will be aggregated into the cloud server to form a huge network, industrial robots will have a “near and far” brain to help them calculate, plan the best production patterns and make the best overall decisions. 5g will give a big boost to smart manufacturing.

 

 

 Conclusion

Different from the consumer sector, industrial manufacturing requires higher reliability and stability, and it is difficult for the current network operators to meet the industrial demand. In addition, the efficient application of 5G should be based on highly developed industry. In order to give full play to the role of 5G, not only individual manufacturers need to improve, but also the production environment needs to be refined at the same time, there seems to be a long way to go before it becomes possible to implement high precision and high speed equipment, improve the digital level of production, facilitate the formation of industrial data networks… there is still a lot of basic work to be done by us.

 

According to the statistics of China Machine Tool Industry Association, in the field of metal cutting machine tools, in 2018 China produced a total of 488610 metal cutting machine tools, of which 190642 CNC metal cutting machine tools, CNC machine tools accounted for less than 40% of the total output. In promoting production digitization, China is still in a relatively backward position, in order to achieve the entire industry digital, networking changes, and large-scale application of 5G network, but also need machine tool people more difficult and more sustained struggle.
