An ETRI research team has unveiled a technology that can remotely control a factory at home and abroad using 5G technology developed through a joint international and intercontinental cable network.

The Institute of Electronics and Telecommunications Research (ETRI) has announced that it has succeeded in proving the Industrial Internet of Things (IIoT).1)) a service that monitors and monitors intelligent factory facilities and robots in real time, both at home and abroad.

The core of successful technology is the very low latency communication technology. The communication delay of more than 10,000 km (approximately 6,200 miles) is less than 0.3 seconds. It has been proven that the Gyeongsan plant in Gyeongsangbuk-do can be monitored in real time from the University of Oulu in Finland.

A smart factory is called a smart factory that increases productivity and reduces failure rates to improve industrial competitiveness by applying information and communication technologies (ICT) throughout the manufacturing process. The core is being remotely controlled by various processes while automating tasks using robots.

In order to avoid damage due to communication errors, communication delay and data loss should be reduced, although the speed of data transmission is also important. The greater the communication distance and the more complex the communication network, the greater the delay and data loss. In this case, low latency and high reliability communication technology is required.

Based on this technology, ETRI has connected a smart factory at the Korean Institute of Industrial Technology, located in Hayang-eup, Gyeongsan-si, Gyeongsangbuk-do, to Oulu University using the 5G test network and home test at Oulu University in Finland. network (KOREN2))

This exhibition presented a new remote manufacturing diversification service, which controls a factory independently at home and abroad. This is the world’s first attempt to improve the service environment and usability of smart factories.

At the Oulu Control Center, the following is demonstrated: ▲ Remote control and monitoring of mobile manufacturing robots ▲ Remote control of the manufacturing process using virtual reality (VR) equipment ▲ Remote control of the manufacturing process by collecting data from wireless broadband-based sensors. of Things (NB-IoT).

Above all, it has significant significance, as it has managed to demonstrate a real-time remote control and monitoring service with a two-way delay of less than 0.01 seconds in Korea and less than 0.3 seconds abroad.

The aim of this exhibition is to strengthen the sharing and cooperation between manufacturing and production countries, increasing the range of intelligent remote manufacturing services based on stable communication quality. Because it is becoming easier to control the opposite side of the earth without visiting the physical site.

Remote control makes it possible to use inactive equipment efficiently in each industry, which is expected to gain strength in global resource management and SME industry competitiveness.

Il-gyu Kim, head of ETRI’s Mobile Communications Research Division, said: the existing industry is expected to recover. ‘

In the future, the research team plans to conduct follow-up research to ensure connectivity and mobility and to implement hyperspace services.

In addition, it intends to work on the design of future 6G-equipped factories through the ongoing collaboration with the flagship 6G program developed by the University of Oulu.
