As the maritime gateway of the Beijing-Tianjin-Hebei and “Three North” regions and the main outlet of Xiongan New Area, Tianjin Port is the intersection of sea and land in the “One Belt and One Road” and an important node of the New Eurasian Continental Bridge Economic Corridor. Head towards the sea and keep walking. In recent years, Tianjin Port has continued to apply innovative technologies, strive to build a technologically powerful port, and accelerate the construction of a world-class port.
Tianjin Port has extensively applied 5G technology into all aspects of terminal production and management. It has become a key support for the smooth circulation of data resources and an important engine leading the intelligent and green transformation and upgrading of the port. However, 5G cannot fully meet the requirements of port applications for large uplink bandwidth, deterministic latency, high reliability and precise positioning. Recently, Tianjin Port Group, together with Huawei and China Unicom, completed the country’s first port scenario integrated synaesthesia capability verification at the Tianjin Port Pacific International Container Terminal, jointly entering the 5G-A era and helping the port achieve industry leadership.
Unmanned trucks shuttle freely at the dock, but workers are hard to find in the port with huge throughput. In fact, unmanned trucks have to face many complex and changeable environmental road conditions such as line intersections, miscarriage, and personnel target avoidance, which puts forward higher requirements for the management and dispatch of unmanned trucks. Based on 5G Uu-V2X vehicle-road collaboration, 5G-A synaesthetic integrated sensing and other technologies, the unmanned truck has the capabilities of beyond-line-of-sight road condition perception, autonomous driving, driving prediction, and automatic alignment. The port has the ability to control unmanned vehicles. The ability to sense the location, trajectory and speed of the container truck can realize all-weather unmanned transfer operations, and the collaborative intelligent dispatch management platform can greatly improve the efficiency of transportation operations and the safe production level of the terminal, and bring good economic and social benefits to the terminal.

5G-A (5G-Advanced) is an evolved and enhanced version of 5G. It has 10 times higher communication capabilities than 5G, 10 times higher bandwidth speed, 10 times lower latency, and 10 times higher connection density. It has greatly accelerated the Internet of People, the Internet of Things, The connected car industry and communication sensing business are upgraded. Synaesthesia is a key capability of 5G-A. Its sensing principle is similar to that of radar. When wireless signals pass through different media or objects, different changes will occur due to reflection, refraction, and scattering. By analyzing this change, the object can be detected It can not only meet the needs of high-precision perception, but also provide ubiquitous synesthesia and computing fusion services by integrating multiple technologies such as mobile communications, radar, and computing power to break through the traditional communication dimension. There is no doubt that 5G-A synaesthesia capabilities have a wide range of application scenarios.
The application of 5G-A technology at Tianjin Port Pacific International Container Terminal marks the feasibility of 5G-A application in the port and shipping fields, and can better serve the safe production operations of port terminals, forming a reference for the industry’s application of innovative technologies. In the future, Tianjin Port will apply and verify 5G-A technology in more scenarios, including offshore channel ship monitoring, external container truck trajectory tracking, complete mixed operation of internal and external container trucks, illegal intrusion into terminal parks, etc., to improve port production and management and control levels. Tianjin Port will continue to apply innovative technologies to help upgrade and build smart ports to better serve the development of logistics trade.
