Hi, I'm here again~ Today I want to talk to you about the application of digital twin technology in port scenes. Everyone is welcome to post and discuss~ (The full text is 2000 words, expected to read for 6 minutes)
1. Definition
Before talking about technical applications, let’s first understand the concepts of several keywords:
1. Ports: Ports are comprehensive transportation hubs and an important part of the construction of a powerful transportation country.
2. Digital twins: Digital twins, also known as digital mapping and digital mirroring, refer to the simulation of physical entities, processes or systems within an information platform, similar to the twins of physical systems in an information platform. With the help of digital twins, the status of physical entities can be understood on the information platform, and even the predefined interface components in the physical entities can be controlled, thereby helping organizations monitor operations, perform predictive maintenance, and improve processes.
3. Smart port: Smart port refers to the promotion of digital and intelligent development of ports based on modern information technology.
Two, the reason
After clarifying the definition, let's explore why modern society uses digital twin technology to build smart ports?
1. Policy support
The "14th Five-Year Plan" clearly stated that digital reform and "digital seaport" will be one of the "Ten Significant Achievements". Focusing on system reshaping, business reorganization and process reengineering, and closely following horizontal synergy and vertical connectivity, build a digital reform work system, "Digital Seaport" operating mechanism, "Digital Seaport" data service platform, and "Four Ports" cloud platform. A large number of major application scenarios make "digital intelligence" the most important symbol of a strong port with first-class management and first-class technology.
In September 2021, the Ministry of Transport issued the "Action Plan for New Infrastructure Construction in the Transportation Field (2021-2025)" document, which requires further promoting the construction of smart ports and promoting the intelligent upgrading of container terminals such as Xiamen Port.
In December 2021, the State Council issued the "14th Five-Year Plan for the Development of a Modern Integrated Transportation System", which once again put forward clear requirements for the construction of smart ports, requiring all ports to intelligently transform existing container terminals.
On August 16, 2022, the Ministry of Science and Technology of China issued the "Notice on Supporting the Construction of New-Generation Artificial Intelligence Demonstration Application Scenarios", which mentioned that for key business links such as large-scale port berths, quayside bridge management, storage yards, and loading scheduling, the use of Key technologies such as intelligent terminal machinery, digital twin integrated production space-time control system, and intelligent solutions for operation monitoring and equipment health management are developed to create a world-class super-large intelligent port.
2. Development trend
The development of smart ports is the demand of the development of the times. With the development of economic globalization and the continuous improvement of my country's comprehensive national strength, ports, as an important way of foreign trade, bear more and more transportation pressure. The development of smart ports provides new ideas for the increasing pressure of port transportation. At the same time It is also an important aspect to conform to the development trend of the times and use modern scientific and technological means to promote the development of smart transportation in my country.
Nowadays, the development of my country's smart ports has made significant progress. Many important ports such as Tianjin Port, Qingdao Port, Ningbo Port, and Dalian Port are becoming more and more intelligent, which greatly saves labor costs, improves the efficiency of port transportation, and speeds up The development of my country's foreign trade.
3. How to realize the integration of port and digital twin technology to build a smart port?
From the analysis of definitions and reasons, the building of smart ports is an inevitable trend, so how should we build them? Next, we take the digital twin port smart application construction of a large port group as an example
(1) Difficulty analysis
(1) Information and data are scattered. There are many applications of information systems in large ports, and the data is scattered and cannot be presented on one platform, making it difficult to make correct decisions based on data.
(2) It is difficult to improve operation efficiency. Efficiency is the lifeline of a port. The digitalization of a single link is limited to improve the efficiency of the entire port operation, and needs to be integrated and upgraded for the entire process of operation.
(3) It is difficult to make macro decisions. As the industry's comprehensive requirements for large ports are getting higher and higher, port decision makers have to face pressure from the market, airlines, and regulatory authorities, and face complex decision-making problems, and urgently need to strengthen their ability to respond to opportunities and challenges.
(2) Idea construction
Through advanced digital technologies such as BIM, twinning means, big data, cloud computing, and intelligence, a twin simulation scene in the port area is constructed, and a digital port that is "twinned" with the physical port is formed simultaneously. Integrate all the basic spatial data of the port, current data, planning results and other related information, realize merger and superposition in the digital space, and realize the port from planning, construction, management to the whole process, all elements, all-round digital simulation and visual display.
(3) Scenario Planning
(1) Dynamic simulation of port operations
Combining the data of ships, storage yards, traffic, weather, IoT devices and cameras, the real-time dynamics of all elements can be displayed through the 3D visualization platform, and operations such as movement, rotation, and zooming can be realized in key perspectives of the simulation scene through interactive control methods such as the mouse , and support the information viewing of ships, business sectors, and specific terminal companies, which can help dispatching and commanding personnel to accurately, real-time, and comprehensively monitor and grasp the production and operation information of the entire port.

(2) Intelligent operation in the port area
The digital twin technology can receive the data information returned by the various subsystems of the port in real time and sort out, store, analyze, and present it, so as to take a look at the overall situation and coordinate all parties. When the data is analyzed to be abnormal, it will intelligently identify the problem, give a reference solution, and promptly inform the relevant responsible personnel to deal with it. Managers can grasp the detailed situation of each department in the port in real time, and can realize remote operation, remote transmission and dispatch control of each link.

(3) Collecting truck command and dispatch
Through high-precision positioning equipment, the positioning information, operation information and other data of the collection trucks in the port area are sent back to the digital twin port platform in a timely manner. The platform managers can manage the collection trucks through the twin scene and find out the abnormal information of the vehicle operation in time. , dispatch operation resources from the global dimension of the port area, and improve the overall operation efficiency and throughput capacity.
