For Rizhao Port , upgrading from a traditional wharf to a "Chinese sample" that attracted the attention of the world, it has been enough to create too many "miracles" in 14 months: the world's first "strait side loading and unloading + unmanned collection and card horizontal transportation" process; realizing the first implementation of unmanned driving in the global port industry; creating a precedent for the transformation and upgrading of traditional wharfs to an automated container terminal, with a 70% reduction in overall cost; for the first time, the TOS of Beidou +5G and domestic dock operating system TOS are successfully applied to the full process of fully automated container operations, realizing centimeter-level precision operation... This is the smart power from new technologies and new models such as artificial intelligence , 5G communication, blockchain, Internet of Things, and cloud computing .
Strive to the ocean and prosper towards the sea. Today, Rizhao Port has become a "high-quality test field" for a technologically powerful country. In its stride forward, it is inseparable from the 5G power given by China Telecom , which is steadily advancing with the "cloud-network integration" as the core, and the network is steadily advancing with the cloud movement and the cloud-network. It is particularly worth mentioning that China Telecom Shandong Branch helped Rizhao Port to build the world's first open and fully automated container terminal on the shore.
In a 650-meter × 260-meter operating surface in Rizhao Port G District, 12 telecommunications 5G road base stations are distributed in an orderly manner, and 15 unmanned card collection cards are moving smoothly at a speed of 20-30 kilometers per hour. As the railing in the G02 area is automatically lifted, the unmanned card that travels from east to west slowly stops. A manned social card drives into the work area from outside. The V2X system indicator light turns from yellow to green. The railing falls, and the unmanned card continues to move according to the original route. The A17 track crane corresponding to the lane where the social card is located begins to operate.
uses 5G signals to identify whether the vehicle entering the lane is unmanned and determine who should get the right to . What you see most intuitively here is actually the application of vehicle-road collaboration between V2X systems. As an advanced wireless communication technology, V2X aims to help vehicles drive smarter and safer on the road through fast communication between vehicles, people and intelligent infrastructure. Common in-car navigation displays traffic light countdown data in real time, which is one of the functions of the V2X system. In order for this function to truly play a role in the road, the corresponding communication system must have the characteristics of high speed and low latency. "China Telecom's 5G RRU+PAD precision dedicated network has found its place to work here." Kong Xiangbin, product manager of Yunzhongtai 5G custom network of Rizhao Branch, introduced.
On the one hand, the coverage method of the 5G network has been changed from a solution with a high lighthouse and wide coverage to a solution with low coverage and precise coverage for the operating area of the unmanned card; on the other hand, 5G RRU+ directional narrow beam antenna is used for the first time, and the technology of super-cells is flexibly merged, reducing network switching during vehicle movement, improving reliability, and meeting many needs such as strong mobility, large bandwidth requirements, high network quality requirements, and high network stability requirements. "A technology to flexibly merge super-coffees is mentioned here. It is a technical method we take to consider the road characteristics of the container port yard." According to Kong Xiangbin, in order to minimize the frequency of 5G signal switching in the vehicle during operation and the 5G signal blind spots in the operating area, an 8TR RRU is installed back-to-back between the north-south road of the operation surface of the G area, and the external horizontal lobe angle is 35 degrees four-port antenna, facing the road coverage. Install the 8TR RRU on the west side of the east-west road. Merge 4 RRUs in the northern area into one super cell, and merge 4 RRUs in the southern area into another super cell.
In view of the characteristics of automated container truck operation, the base station side adopts 5G dual carrier technology China Telecom's proprietary super uplink solution to expand the uplink bandwidth of 5G, and at the same time, dual CPE load balancing is used on the vehicle side to realize redundant network backup, ensuring high availability of large uplink bandwidth of 5G networks.
At the same time, China Telecom Shandong Branch deployed a port-specific 5G mobile edge computing platform (MEC for short) at the Rizhao Port container terminal. The 5G dedicated network combined with MEC ensures uninterrupted high-quality network guarantee for remote driving applications, sinks the core network user surface to the Rizhao Port container terminal, realizing that the enterprise business data does not leave the park, providing higher security guarantees, while meeting the personalized needs of fully automated container terminals for high-definition video backhaul and massive machine-type communication, and is the cornerstone of smart port information transmission.
has been upgraded from the "intelligent" manufacturing of traditional wharfs, to the unmanned and people who switch to the line at any time and then to the port's "brain" to "cloud" in real time. With the commercialization and operation of the industry's first 5G-based L4 autonomous driving technology in the port, it has been upgraded from a traditional wharf to a fully automated container wharf, and has supported a "5G halo" of Telecom .
"In the eight months of trial operation, China Telecom Shandong Branch formed a team of 5G engineers, smart home engineers and manufacturer staff. Together with the port staff, they gathered an elite team in one operation." That period of eating and living together made Ni Bo, head of the IT department of the Rising Automation Operation Center of Jifa Company of Shandong Port Rizhao Port, recall to this day, "At that time, in addition to the internal infrastructure projects of the port area, even optical cables were inspected. The telecom staff could not only provide us with comprehensive solutions to problems, but also have a positive attitude and first-class service capabilities, and demonstrated the responsibility and responsibility of central enterprises in the field of 'intelligent manufacturing of big countries'."
In Ni Bo's view, the smart dock is like a miniature version of a smart city, and it is also a With mutual coordination and efficient cooperation between multiple sections, 5G smart wharf solves the seamless connection and coordination problems between various wharfs, bridge cranes and collectors. "5G solves a lot of uncertainty in the port operation process. This free dispatch and real-time cooperation like factory assembly line gives Rizhao Port a stronger 'vivability'." At present, Rizhao Port is widely engaged with China Telecom Shandong Branch to continuously coordinate the relationship between port smart green development and economy, society and environment, break the boundary of port city , strengthen the connection between port smart green master planning and urban development, empower the industry with technology, and allow the concept of "smart green port +" to be widely extended to all areas of the entire industrial chain, and realize the deep integration of digital economy and the real economy.
Ports prosper the sea and move towards the world, and 5G cloud networks move towards the future. Empowering port wisdom with technology, rationally allocating and scheduling port resources, and making port operations more reliable, efficient, greener and smarter have always been the unremitting pursuit of major ports in the world. As one of the "two wings" of the "smart port construction pilot" unit of the first powerful transportation country in the country, Shandong Port Rizhao Port is working in depth with China Telecom Shandong Branch, combining telecom's resource endowment, empowering with 5G and driving with technology, and relying on a large integration of ports across the province, it is committed to rewriting the overall pattern of the global shipping market.
