Doosan first to use 5G for
worldwide ‘TeleOperation’
In what wass one of the highlights of the Bauma 2019 exhibition in Munich in Germany, Doosan is the first manufacturer to use 5G technology for worldwide ‘TeleOperation’ of construction machines.
Doosan has coined the term TeleOperation to describe the operation of construction equipment from a remote station. At Bauma, remote really means remote - operating a Doosan DX380LC-5 40 tonne crawler excavator located over 8500 km away in Incheon in South Korea from an operator’s booth on the Bauma stand in Munich.
‘Powered by Innovation’
TeleOperation forms part of Doosan’s exciting stand display at Bauma under the banner of ‘Powered by Innovation’ and has been co-developed with LG U+, the South Korean telecommunications and data services company. The TeleOperation demonstration on the Doosan stand is the first to remotely control a machine across such a large distance between locations which have a time difference of eight hours, using 5G telecommunications technology.
For TeleOperation to function properly, it is essential to deliver live video streaming at the operator’s station in a reliable way that minimizes time lag in the system for the operator. With its ultrareliability and low latency (signal delay), the new 5G network overcomes these issues in the Doosan system, providing 10 times faster bandwidth and 10 times lower latency than the 4G network.
New 5G TeleOperation Open to Stand Visitors
The exciting 5G TeleOperation system was demonstrated throughout the duration of the show, with set times every day to give visitors to the Doosan stand an opportunity to try the system out for themselves.
Because the LG U+ platform provides a 5G connection that is 5-10 times faster than current 4G systems, the operator has the same real time control of the remote excavator and with the same high accuracy. 3D machine guidance, real time diagnostics and a full gauge display are all available at the Teleoperation control booth.
Whilst it can be used for general earthmoving applications, the new Teleoperation system is ideal for operating
excavators in dangerous applications such as industrial waste disposal, involving hazardous, toxic or radioactive substances. It is also useful for work
on collapsing waste piles and in areas where there are buried mines and other munitions.
Safety can be further increased via the zoning and area limitation functions
available through the Doosan TeleOperation system.
Special features incorporated
include a low-latency video
transmission module with fast video transfer (with encoding and decoding), an important factor in reducing the time delay.
LG U+ has also introduced new modules providing low latency image processing to
further minimize the time delay. Another factor in creating more effective remote control is the use
of Doosan's innovative electrohydraulic technology in the DX380LC-5 excavator.
The DX380LC-5 excavator being remotely controlled at Bauma is still a standard machine, which allows Doosan to guarantee the performance and the compatibility of third
party attachments and other equipment installed on the excavator. It is also possible to carry out both normal operation and TeleOperation with same machine.
