"In the era of 5G, smart factories will emerge."

It is a sentence that is frequently seen whenever a business model of 5G or a killer service is discussed. However, there have been few cases where only words were mentioned and materialized, and only 5G Smart Plant, which was only talked about, was seen at a glance.

SK Telecom (President Park Jeong-ho) experienced 5 types of solutions that are applied with 5G and high-tech ICT that will form 5G Smart Factory at 'Smart Manufacturing Innovation Center' located in Ansan, Gyeonggi Province on the 20th.
High-speed, ultra-delay and multi-connectivity are the main characteristics of 5G. Through these three characteristics, functions that are used in Smart Factory are infinite. By taking pictures of components, they can select defective products and help transport them by working together with robots. Information on facilities and components can be viewed at a glance through AR. The practice of self-regulation is carried out.

'5G Smart Flexible Production Facility (SBB)' is a back-mi that can see strengths of 5G wireless at a glance.

In the past, it is common to recall that the long conveyor belt was completed in each stage. In other words, once the production line is established, the factory will only produce digestible products. If it is to manufacture other products, it is expensive to remodel or reveal production lines.

However, if these production lines are split and made into a single block, they will be able to combine the blocks as needed to manufacture a variety of products within one factory.

The 5G SBB is equipped with a robot arm for manufacturing parts and a module that is 1.5x1x2m in size. 3 to 10 modules that are in charge of production, inspection, and packaging are assembled to form a single production line.

What's surprising is that each block runs autonomously. When ordered, blocks gather and create new production lines. It also showed that its packaging blocks, which are separate from the site, perfectly docked to the existing production lines through self-driving technology.

Regarding this, Song Byung-hoon, director of Smart Plant Diagnosis Center, emphasized that manufacturing businesses need only empty factories. Blocking of production lines is easy to transport to other factories. <a href="https://www.betsarang.com">안전한놀이터</a>
Space efficiency can be achieved at any time because it moves flexibly rather than a fixed production line.

"The existing production lines are mixed with countless wires, but SBB was made of blocks by minimizing the lines," Song said. "But the SBB's docking should be perfect, as well as self-control. At this point, 5G's ultra-low delay capability will be demonstrated."

If your production line needs new features, you can add more modules, or if you want to reduce the process time, you can remove modules. 5G is used to wireless sensors, controllers, and robotic arms that are automatic components of each module. It also analyzes efficiency of processes by transmitting Big Data that occurs per module to a central computer.


✓ Mobile Edge Computing (MEC), behind-the-scenes in a private smart factory

5G-AI Machine Vision is also drawing attention with other technologies. This technology is also a solution that was applied by SK Telecom to famous industries as 5G service that was commercialized on the 1st. This solution also shows characteristics of 5G.

5G-AI Machine Vision, which is also a solution for South Korea's first 5G industry, takes 24 pictures with a 12-megapixel camera while parts of a car pass through a conveyor belt and sends them to a cloud server through 5G. A high-performance AI on a server reads pictures instantly and checks if a product is defective.

"The 5G-AI machine vision can increase per person's productivity up to twice by working with employees." said.

The core of this technology is actually Mobile Edge Computing (MEC). In current LTE, when a signal is received from a base station, it is connected to a telephone station and sent to a cloud server. Results computed by the server are then communicated to the end user via the opposite path.

However, MEC is going to deploy Cloud Server that is being pushed back to base station. Although there are performance differences at the end, there is no need to go to the back servers and solve them. This will allow you to process large amounts of data faster and without delay.

According to a field official, about 600MB of capacity is generated each time the 5G-AI machine vision, which is applied to a famous painting industry, takes a picture of a part. If you take one shot per second, you have to process 6GB of capacity in 10 seconds. Although it was difficult to handle such large capacity in LTE quickly and without delay, it is possible to do so with the help of MEC in 5G.

MEC has excellent security. If the signal goes from the end to the main, all sections must be highly secure, but the MEC is handled by a cloud server near each base station. In other words, it is possible to centralize security since data only comes and goes from within the workplace.
