Real -time digital twin is not a simple copy game

Since the birth of digital twins, it has gone through the formal evolution of different stages of form. From the early scenes, it is reorganized to the display and description of the real world, and has real -time data mapping capabilities. It is applied in the field of aerospace; today, real -time digital twins have a variety of technologies such as simulation simulation, AI, cloud computing, 5G, etc., have the ability to analyze and calculate, and even have the ability to influence and transform the real world.

Digital twins are widely used in industries, construction, urban management and other industries. In the field of construction, BIM is the main cost, which greatly reduces the cost of planning, construction and management; in the industrial field, Industry 4.0 uses digital twin technology as the core application to improve the flexible level of manufacturing; It is providing intelligent scheduling for each crossroad, or escort the safety and efficient operation of highways. On the whole, data show that the digital twin global market will maintain a compound annual growth rate of 58%.

Tencent has invested in the research of virtual simulation technology since 2016. It first applied it to the autonomous driving algorithm test and verification. In the process, the core capabilities required for digital twins have been continuously accumulated, such as high -precision three -dimensional reconstruction technology, dynamic trajectory reconstruction, and reconstruction of dynamic trajectory. Integrate perception, real -time calculation, etc., and expand the scope of application to smart transportation and other fields. In the process of participating in the highway, urban transportation, subway, port, and intelligent network pilot zone, the value discussions on digital twin technology on existing traffic scheduling management, process optimization and reconstruction of the digital twin technology have become more and more in -depth. The current basic consensus of the industry has been reached -quite critical.

This is not limited to theoretical discussion.

In the cooperation of smart high -speed projects such as Tencent and Jiangsu Traffic Control, Guangdong Expressway, Shu Road and other smart high -speed projects, the technology of real -time digital twins is playing a role in solving problems such as all -weather passage and congestion of highways; Suiten OS, real -time digital twin technology has reached innovation of the functional iteration process of the rail transit system.

While exploring technology and industrial applications, Tencent promoted the international standards for the first digital twin demand and capabilities of intelligent transportation systems in the ITU.

Some industry experts who have deeply understood Tencent's digital twin technology and applications said that there is no field that can connect Tencent's technical accumulation in the fields of games, maps, clouds, big data and other fields like smart transportation; Like twin technology, it plays a key role in defining and transforming the world of digitalization. In this issue, Shi Xuesong, vice president of Tencent Smart Transportation, Su Kuifeng, general manager of Tencent Transportation Platform and Tencent Autonomous Driver, will define "digital twins" on how Tencent, Tencent's digital twin technology leading sources. As well as questions in the future direction of key layout.

Talking about digital twins today, it may be easier for people to understand the TOCC screen?

The industry's understanding of digital twins today is not completely in place. In the past few years, the transportation industry has misunderstood digital twins. The application of large TOCC screens (traffic operation monitoring and command centers) in various places is actually data visualization. Only visualization is not called digital twins. Visualization is just a small sub -item in the middle of digital twins.

Today, Tencent focuses on the "real -time digital twin" technology. For the special needs of transportation, industry and other fields, the twin scenes must be more realistic, more fresh, easier to be understood, and more intuitive to display the operation of the physical world, "real -time" and "Calculated" is the most fundamental starting point for our real -time twin technology.

Tencent Smart Transportation Real -time Twin System

For example, in the field of transportation, in order to solve some complex and difficult problems, real -time twin technology must be used. For example, the tunnel of high -speed or ordinary highways should achieve closed -loop control (or active control). In the past, we only rely on some cameras or smoke sensors for sections to detect. Now we can use real -time digital twin technology to show the entire road environment in real time. It is for the machine to see the autonomous driving monitoring of highways and tunnel traffic events to achieve the coverage of no dead ends. At the same time, we can also render some of the information on the large screen of the TOCC. To information. Our technical route is being promoted, including many traffic scenarios such as subways, airports, high -speed, ports, and urban hubs.

Why does Tencent emphasize "real -time twin"?

Here we will talk about our understanding and definition of real -time twins. It is mainly based on the accumulation of experience simulation, AI, and cloud computing, combined with information, calculation, modeling and other information, to digitize physical space into a calculated digital space.

Calculation is very important. Only turning the physical world into a model, monochrome, including data and forming a data flow. This is a calculated space. In this calculated space, we can describe, diagnose, predict, and decide the physical space to achieve closed -loop control. The virtual world can interfere or transform the physical world, and then realize the interactive fusion of physical space and digital space. This interaction integration and control require real -time interaction in more applications, so we call it "real -time twin".

Data is the foundation, and the data comes from digitizing the physical world through sensors. The model is the core, the data is transmitted to the model, the model is re -mechanized, simulated, and even the maintenance and prediction of the whole life cycle. Services are the focus. Either collect data or establish a model. In the end, we still emphasize the scene. We are more emphasized to serve the scenes, including intelligent analysis, simulation prediction, etc. This is our core of our core The focus. Real -time digital twin closed -loop process

What advanced technologies do "real -time digital twins" fuse?

Tencent's real -time digital twin is mainly based on simulation, AI, and cloud computing, which better associate the physical and real world, build digital space, and accurately describe it. The technologies that need to be used include IoT, multi -data fusion, 5G cloudized core network, 4G & 5G hybrid application, public cloud/private cloud rendering, trajectory optimization algorithm, high -quality game technology, simulation simulation technology, etc. At the same time, you can also use Tencent's position to have a large location. Data and other capabilities realize the interoperability of information, better deduce and predict, so as to better provide managers with decision -making basis.

What are the specific advantages of digital twin technology with "real -time calculation"?

Tencent's real -time digital twin based on traffic flow restoration can achieve a 100 millisecond low latency (equivalent to the speed of human blink).

Especially for the field of transportation, the importance of "real -time calculation" is reflected in several aspects. First Master the information as soon as possible; second, it is necessary to quickly form decisions through calculated models, and respond to emergency measures at the same level in a timely response in response to the accident. Quickly simulate the more reasonable control measures. On the one hand, the upstream vehicles are managed and controlled in time through intelligence boards, road side equipment; on the other hand, push to the surrounding related people through mobile phones and other methods in time, as well as corresponding rescue teams. For the disposal of traffic safety accidents, time is life.

Road test all -weather perception and real -time digital twin

Taking traffic scenarios as an example, how can Tencent achieve "real -time" and "calculation"?

In real -time digital twins, we must be accurately expressed. First of all, we must accurately perceive the processing, integrate the polygonal data, and connect the data of each unit based on the high -precision map data, and then connect the data of each unit to form a coherent space; the second step; the second step It is a model analysis, which mainly uses the two methods of mechanism models and data -driven models; the third step is to calculate analysis to provide decision -making basis for the optimization of the real world; finally Human careful service.

Take Sichuan Province as an example, frequent rainstorms during the flood season, and the baire in the autumn and winter foggy weather. In 2021, the average number of fogs in Sichuan Province is 41.0 days, and the number of days of transportation is not good for the number of weather (large fog and heavy rain day). 175 days. The digital twin solution that Tencent and Shu Dao Group are piloted by the Shu Dao Group, through the method of collaborating with the V2X vehicle circuit, based on data perceived data and real -time rendering technology, the dynamics and location information of the peripheral vehicles are pushed to the driver's mobile phone or vehicle machine. In the obstructive rain and fog weather, it plays an important role in traffic safety prevention. And in such an extreme weather environment, the perception of millimeter wave radar cannot be realized, and the millimeter wave radar reliability is higher and the maintenance cost is lower. Essence

What is the origin of real -time twins? What is the role of this origin during the digital upgrade of the physical industry?

Behind the real -time twin is actually a set of data -driven thoughts. This is also its origin. The upgrade of the physical industry must be based on the ability to realize completely different from the information era, that is, the ability of data -driven. If the information management of the past dependent solidification process cannot be achieved, and the agility iteration of the business process is evolved to rely on data -driven to realize the business process, this digital transformation cannot be successful.

Today’s digital transformation must be based on a brand new digital base. The real -time twin capabilities will play a role on this base. Combined with Tencent's OS system for the Industrial Internet, companies can use its real underlying capabilities and several built The data of the IT system is uniformly tube. After realizing different system equipment and data into management, we can build a twin system well. Then we can provide low -code business arrangement capabilities and low -code strategic engines through better development tools, which is convenient for enterprises to adjust and optimize their business processes to be easier to adjust and optimize their business processes.

Smart rail transit system

For example, after the water flood in Zhengzhou Metro last year, subway groups everywhere attached more attention to flood prevention capabilities. The Guangzhou Metro has built a new flood and flood -resistant module. In the past, it may take tens of millions and spend more than six months. Today, it only takes two weeks to achieve comprehensive deployment on the digital base. So this is a fundamental change.

After the digital base is completed, after the real -time digital twin capabilities are built, the evolution of the business will endlessly. Even if the process is completely disrupted, this base can still be used, and this base can continue to expand and expand capacity. For example, the entire Guangdong government services are running in Guangdong Province, with Yuekang Code, Yue Nucleic acid, etc., and more and more functions, but it is getting more and more stable, more reliable, and more efficient. Because the infrastructure behind it is evolving forward at all times, it slowly disappears. Therefore, the construction of digitalization must be systematized, based on the top -level design of real and effective digital transformation, in order to achieve smaller investment than informatization, but achieve higher returns.

Digital twin has a wide range of industry application value. Do Tencent meet these needs through themselves?

For more and more extensive industries, Tencent is committed to the establishment of twin infrastructure. For more upper -level application development, we need to build with partners. To this end, Tencent has also built a real-time twin open platform to allow people who have more vertical industries Know-How accumulated to build more industry applications on the platform. At the same time, we will provide a multi -user collaborative twin platform to enable multi -user coordination to operate in the same frequency in the virtual world and the physical world. These are two very important platforms. In addition, we will also provide immersive visual device interfaces to support more industries and continuously iterate and improve the real -time twin architecture.

In the application of real -time twins, what other challenges should be overcome?

The evolution of digital technology is promoted by the market, and standard drivers are also required. To achieve the state of all things, industry standards that need to be interoperable. As a member of the ITU (ITU), Tencent led the country's first digital twin standard for smart transportation systems. In the past standard fields in the field of intelligent transportation, most of the dominant power was controlled by Europe, America, and Japan. What we need to do is to strive for standard dominance. At present, we are also sorting out the standard system of Tencent's real -time twin, and gradually establish and improve such a standard system internationally and domestic, so that standards, technology, and industries can be promoted and implemented at the same time. In the field of communication, Tencent has always been the first standard contributor in Internet companies. We will also integrate the 5G communication standard system into the real -time twin technical system to build a more complete twin body from perception to reaching reached. Essence
