The sky in Shenzhen, Guangdong is very busy: 3,000 logistics drones shuttle and pass by every day, and dozens of helicopters fly over the city.
The low-altitude economy is booming, but how to ensure the aircraft is orderly and safely flying? Recently, the reporter visited Shenzhen Smart City Technology Development Group (hereinafter referred to as "Shenzhicheng") to find the answer through a virtual city.
On the large screen of the Demo City Demo Hall of Shenzhi City, the invisible routes in the real sky are particularly clear in the virtual 3D world. "The digital twin cities copied through equal proportions can better provide technical support for management and scheduling." Zhao Yingying, technical director of Shenzhen Intelligent City Research Institute, introduced that in this virtual city, the construction facilities, street parks, and real-time road conditions are clear at a glance.
What's the use of spending a lot of effort to build a virtual city? "Digital twin cities are like a mirror time and space." Zhao Yingying said that reality can dynamically map to the digital world, thereby simulating, predicting and managing city operations.
"Virtual cities can access data in the real world as needed and develop various applications and scenarios." Zhou Ziyi, director of the Shenzhen Intelligent City Technology Department, said, "For example, it takes only 5 seconds to deduce the urban traffic conditions in the next 2 hours. At present, the accuracy of the relevant deduction has reached more than 90%."
In Shenzhen, digital twin applications have been integrated into the daily life of citizens.
Want to charge new energy vehicles? Zhao Yingying demonstrates on-site: Click on the "iShenzhen" APP and you can immediately find the nearest charging station, check the spare parking spaces and real-time electricity prices.
"Behind the APP is Shenzhen's 'power charging, storage and distribution network'." Zhao Yingying said that relying on digital twin technology, it can provide users with precise services by connecting distributed energy sources such as 414,000 charging facilities, 2,338 photovoltaic stations, and 1,002 super charging stations.
At present, this virtual city has more than 4,000 data services, covering urban management, energy and electricity, people's livelihood services and other fields, serving nearly 800 million data demands.
Shenzhicheng's products are not only launched in more than 160 cities in China, but also entered overseas markets such as the Middle East and Southeast Asia. "In the new year, we will continue to show the 'Chinese solution' of smart cities to more people." said Qiu Jiandong, senior engineer of Shenzhen Intelligence City.
