The first domestic "Digital Twin Bridge" was completed in Hangzhou Bay Cross -sea Bridge

An accident occurred in front of the vehicle, the control information was released within a few seconds, reminding the rear vehicles to pay attention to avoidance; the digital induced screen "lane -level" display, accurately reflect the real -time dynamics of the bridge. A few days ago, the first domestic visual -based all -weather highway digital twin application was completed on the Hangzhou Bay cross -sea bridge. This also marks that the Hangzhou Bay Cross -sea Bridge has become the first "Digital Twin Bridge" in China.

This eleven long holiday passenger cars can pass free of charge. You may be here to get a new driving experience.

The first domestic visual -based all -weather highway digital twin application was completed in the Hangzhou Bay Cross -sea Bridge.

Entering the bridge command center, a huge screen, a "digital twin bridge" presented in the "cloud". This bridge brings together real -time traffic, event graphics, Beidou navigation, traffic conditions, disposal, and disposal on the Hangzhou Bay cross -sea bridge. For key elements such as progress, the "one picture" and real -time vehicle stream trajectory display is realized. Here, all kinds of dynamics and changes on the bridge surface can be mastered in real time, and digital analysis can be performed, waiting for the next step of management instruction adjustment and release.

The Bridge Command Center manages the entire bridge through digitalization.

Then go to the bridge to the bridge, the digital high -definition camera that supports the detection of AI events, the two -way spacing of the whole bridge is 125 meters, and the layout is dense and orderly. These visual devices can cover two -way lanes, ensuring 100%full coverage of the bridge perception capacity. They are like a pair of eyes, providing the necessary visual information for the cloud.

The "Digital Twin Bridge" is equivalent to the digital parallel world in the cloud, and the real -time bridge deck is mapped in the cloud or the meta -cosmic environment.

"Digital twin" is a concept beyond reality. It is to make full use of data such as physical models, sensors, and running history. It integrates the simulation process of multi -disciplinary, multi -physical, multi -scale, and multi -probability. Map, so as to digitally reflect the full life cycle of the corresponding physical equipment. It can be understood that in a virtual environment, a "twin bridge" that is synchronized with the real environment in the virtual environment.

The dynamic and precise traffic induction of the "lane -level" of the bridge.

Based on this "digital twin" technology, the digital model of the entire bridge can be constructed, covering information such as real -time traffic, structural facilities, and blocking status of the bridge. On this basis, the Hangzhou Bay Cross -sea Bridge has completed the compilation and deployment of 108 types of control strategies for the 18 categories of bridge events, such as:

There was a traffic accident such as a vehicle rear -end on the bridge. Where did the accident happen? Do you need emergency rescue and sealing? How many lanes are occupied by the accident? How should the rear vehicle be avoided?

These complex information can be generated in real time, and the "one -click is reached" of the management and control information. In the future, combined with the continuous accumulation of data, using big data analysis and in -depth intelligent learning technology can make a more accurate prediction of the traffic situation, making the deployment of the active management and control strategy more accurate and effective, and truly realize the retrospective of history and simulation the future.

The bridge realizes the "one -click" of the management and control information.

So, how can this information pass to the vehicles and passengers on the bridge? The Hangzhou Bay Cross -sea Bridge has realized the precise traffic induction service of the "lane -level" of the bridge. Through the 1828 set of smart fog lights, 40 full -color induction screens, 346 sets of digital warning radio through the bridge Complete the entire process from intelligent discovery and strategy matching to the release, so that during the process of passing the passengers, obtaining the road conditions information accurately and timely.

There is a car driving every 2 seconds. From the eastern coast of Zhejiang to Shanghai and Su Xichang, the highway is connected directly, and the total energy consumption cost of social energy consumption is 15 billion yuan ... Today, the Hangzhou Bay cross -sea bridge is now in Zhejiang. "The construction of Ningbo Binhai Metropolis brings surging motivation!

Zhu Mei, deputy general manager of Ningbo Trading and Chairman of Hangzhou Bay Bridge Company, told reporters that through digital transformation, in the first half of this year, the incidence of accidents in Hangzhou Bay Cross -sea Bridge decreased by 16.4%year -on -year, and the second accident rate decreased by 66%year -on -year.The discovery rate reached 99%, and the rescue power arrived at the scene to less than 20 minutes.The Hangzhou Bay cross -sea bridge, which has been opened to traffic for nearly 15 years, has entered a new journey in the digital era.Reporter Fan Hong Correspondent Zhang Xueer Xie Wei
