Researchers in Korea have developed a technology that can control smart factories hundreds of kilometers away remotely and in real-time based on 5G and wired networks.
The Korea Electronics and Telecommunications Research Institute (ETRI) announced that it succeeded in demonstrating "ultra-low latency and high-reliability 5G wired and wireless network-based remote industrial IoT service" by connecting the laboratory in no. 11 building of ETRI headquarters in Daejeon and the Korea Institute of Production Technology in Hayang-eup, Gyeongsan-si, Gyeongsangbuk-do.
Smart factories refer to intelligent factories that can automate tasks using robots instead of humans or perform various controls even if they are not in the field.
In order not to cause damage due to process errors when issuing orders remotely, there should be less time delay and no data loss like issuing orders on the spot.
Although there have been cases where 5G has been used to demonstrate smart factories, production facilities have been controlled in real-time mainly within factories by introducing foreign equipment or technology.
ETRI succeeded in controlling facilities real-time as in factories through a remote-control center hundreds of kilometers away by combining its own 5G wireless communication technology and wired network technology.
The services demonstrated by ETRI include ▲ remote real-time production management system ▲ remote real-time production robot control ▲ real-time production facility control and management using remote touch panels ▲ real-time process situation monitoring using remote VR equipment ▲ wireless process monitoring.
For verification, ETRI researchers installed the latest 5G standard-based industrial IoT system (IIoT) at Gyeongsan Smart Factory and Daejeon ETRI Control Center, respectively, and demonstrated the section between the systems by combining wired network technology developed by researchers with KOREN optical tracks.
Through this, round-trip communication within 3 milliseconds in Gyeongsan Smart Factory and within 10 milliseconds between Daejeon and Gyeongsan industrial terminals is possible, succeeding in controlling the real-time remote smart factory manufacturing system for the first time in Korea.
Compared to existing demonstration cases suggesting a round trip delay of fewer than 10 milliseconds in the factory, the technology developed by ETRI is evaluated to have paved the way for full-scale remote smart manufacturing services to be possible in the future.
In particular, it is expected to significantly increase the efficiency of the industrial ecosystem and meet the expanded demand for social non-face-to-face activities due to COVID-19, which will greatly increase the technology of small and medium-sized companies related to domestic telecommunications and manufacturing.
ETRI said it has been able to achieve results by developing industrial IoT systems such as terminals, base stations, core equipment, and mobile edge computing (MEC) platforms according to 5G standards with KT, Korea Institute of Production Technology, Open Object, Qcell Networks, CleverLogic, and Soongsil University since 2017.
Developed by ETRI, this technology has been implemented since March 2017 by the Ministry of Science and ICT, IITP's △ Overcoming 5G performance limitations, high trust, hyper-connected core technology" task, ETRI support project since January 2917 △ ICT-based technology development task, and the Ministry of Science and ICT and IITP's △B5G optical access acceleration and slicing technology task, which has been in place since April 2019.
ETRI is promoting the commercialization of 5G industrial terminal chipsets, modules, and base stations through technology transfer and cooperation with small and medium-sized South Korean companies, so it will also make efforts to revitalize the 5G smart manufacturing market and ecosystem.
In addition, through follow-up research, the company plans to demonstrate the possibility of remote monitoring and control services overseas beyond domestic remote connections to Oulu universities and Gyeongsan smart factories in Finland in early 22.
Bang Seung-chan, head of ETRI's Telecommunications Media Research Institute, said, "This technology will be used as an innovative tool to revitalize 5G smart factories throughout the manufacturing industry. Specially, we will do our best to localize and revitalize related technologies as soon as possible."
