Japan’s KDDI, NEC and construction company Obayashi Group successfully used 5G technology for road projects

Among the technical features of 5G, in addition to greater network bandwidth throughput, low latency is also an important feature of 5G. The easiest to understand display method for consumer applications is cloud streaming. Streaming games, and in the engineering field, there are many application cases for remote machine tool operations through 5G. Remote operation technology can prevent operators from being exposed to high-risk construction environments, and combined with semi-automatic technology reduces the risk of Operators use the skills required to operate professional machine tools; however, most of the current 5G remote machine tool operations are mainly based on technology demonstrations and rarely see actual applications. However, Japanese telecom operators KDDI, NEC, and Japanese construction companies The Dalin team used 5G remote technology to carry out road construction on the spot, and also used three machine tools to operate in the 5G environment at once.

▲This 5G remote operation is mainly based on excavators, bulldozers and sediment transport trucks, while the road rollers use autonomous driving technology

This project was carried out in Mie, Japan The county's Kawakami Dam construction site mainly uses 5G remote technology for excavation, transportation and land preparation; equipment is set up through four machine tools including an excavator, a bulldozer, a sediment transport truck, and a road roller. Three 2K cameras and one 1.2K 360-degree camera are installed on three machine tools that mainly perform remote operations, such as bulldozers, bulldozers and sediment transport trucks. Multi-channel images form the basis of remote vision and are carried out using 5G. data and remote control. Eight 2K cameras are installed at the project site to capture a bird's-eye view of the area that each machine tool is responsible for. A 4K 3D camera is used to capture a bird's-eye view of the entire construction site. Two more cameras are also installed at the site. 3D laser scanning machine serves as an auxiliary to guide the movement and positioning of machine tools.

As for the road roller, it is equipped with sensors and an autonomous driving platform. It will use automated technology to prepare the site, transmit real-time data and monitor the construction quality, and use the positioning system to monitor whether the construction location meets expectations. .

According to the official statement, this 5G remote construction field demonstration will be used as part of the future remote construction management system. It is expected to be able to construct a remote construction site that can control and operate multiple construction sites at the same time. Engineering center, in addition, for operators who are familiar with the system, it is also possible to operate multiple construction sites and multiple machine tools, maximizing the application of Japan's current limited labor force.
