Last night, the opening ceremony of the 19th Asian Games in Hangzhou
It was held in the Hangzhou Olympic Sports Center Stadium
The Asian Games torch was lit in the "Great Lotus" in a way that had never been done before
More than 100 million digital torchbearers, each of whom turned into a small flame, gathered on the Qiantang River, forming a figurative "digital person", stepping on the tide of Qiantang, walking firmly, rushing to the sky above the "big lotus", breaking the barriers of time and space, jumping into the 185-meter three-dimensional net screen, meeting with the sixth torchbearer, "digital and real integration" lighting the main cauldron tower, completing the ignition ceremony, truly embodying the concept of national participation, showing the friendship of "thousands of miles are still neighbors".
Viewers in front of TVs and mobile phones can see the step-by-step process of "digital humans" in detail, which is the first in the history of the Asian Games and the most intuitive presentation of art and digital technology.
How did the first digital torch relay and ignition in history work?
For the first time in the history of the Asian Games, the cauldron was lit by the method of "integration of data and reality". It reflects the concept of national participation. To realize this technology, a group of engineers from Ant Group Alipay developed a digital torch interactive engine technology, which tested and compatible with more than 300 mobile phone models.
"Hundreds of mobile phones of different generations and models have been tested more than 100,000 times, even mobile phones from 8 years ago can participate in it, ensuring that everyone can come to our Asian Games event." Liu Kaiqi, product leader of Alipay, said.
With the help of Internet technology, hundreds of millions of netizens from more than 130 countries and regions around the world have become online digital torchbearers and jointly form AI "digital humans".
"Through blockchain technology, each digital torchbearer can finally receive a certificate on the chain, permanently traceable." Wu Fan, director of the Alipay Asian Games Office of Ant Group, said.
In order to allow the audience to see the gathering of hundreds of millions of digital torchbearers, the Alipay team adopted AR (augmented reality) cutting-edge technology for the first time to create a new immersive interactive experience. As long as the audience points their mobile phone camera at the center of the stage, they can see the scene of the digital torchbearer stepping on the river in real time. To this end, nearly 30 members of the team will sample the different lighting conditions and different viewing angles of each area on the 3 floors of the main stadium in the big lotus for five consecutive times, and then simulate the perspective of the audience in each area through the algorithm model of artificial intelligence.
How does the core installation of the Asian Games torch "Qianjiang Tide" surge?
The torch installation, known as the "Qianjiang Tidal Wave", consists of 19 uniquely shaped columns that form a tidal-like appearance, and the 19 pillars symbolize the 19th Asian Games. The interior of the torch tower adopts a dynamic structure, which can take on two forms: when the "wave" is curled, it is about 10 meters high and the shape is similar to the traditional Chinese auspicious cloud; After the "wave" unfolds, it is about 19 meters high, and the shape is like the tide of the Qian River.
"Qianjiang Tide" is also a mobile torch group, which has been successfully used in large-scale sports events for the first time. Recalling the design and manufacturing process at that time, Li Yang, an engineer from Dafeng Industry, bluntly said that it was not easy: "There is a huge gap between the imaginary animation and the actual work. There are many things to consider, wind load, self-weight, and force load. ”
The torch pillars of the "Qianjiang Tide" are 19 meters high and the thinnest one is only 60 centimeters in diameter, but they must not sway under the eight-level gusts that can blow at any time on the banks of the Qiantang River.
To this end, the design team drew on bionic robotics to divide the torch tower into bionic mechanical skeletons, dynamic decoration and combustion systems. The skeletal part of the largest flare tower is designed with 16 flexible segments to achieve perfect arc and linear transformation, while to ensure precise movement in the millimeter range, the main drive system adopts a mirror-symmetrical precision ball screw structure to ensure speed and smoothness.
"It is a kind of bionic robotic arm, the same principle as the human arm, in order to ensure this stability, the accuracy we manufacture reaches 0.001 mm, which is equivalent to about 1% of the thickness of a piece of A4 paper" Yan Huafeng, chief engineer of Dafeng Industrial Co., Ltd., is very proud of the design and accuracy of this set of equipment.
In addition, in order to ensure that the 19 torches can be raised synchronously, a set of domestically developed intelligent brain control system has been added to it, which can simultaneously control the operation of the four major systems of machinery, combustion, lighting and decoration, and accurately command the operation of each system through data sharing and communication with each system. Not only that, but it can also collect and analyze various data in real time, such as environmental safety data such as temperature and humidity, to ensure that all equipment is in optimal condition.
"We also hope that through such a major international event on our doorstep, we can better show the world that Made in Zhejiang and Made in China will be presented." Feng Jialong, head of Zhejiang Dafeng Industrial Co., Ltd., said.
What is the black technology of the Asian Games torchlight zero-carbon methanol?
At the moment the torch was lit, the fuel zero-carbon methanol emitted clusters of bright yellow flames, lighting up the stage like a tide.
Zero-carbon methanol has realized waste carbon regeneration and CO2 resource recycling, and has five advantages as the main flare fuel of the Asian Games. Environmental protection: efficient combustion, zero emission in the cycle; Safety: not easy to explode, safe and convenient storage and transportation; Reliable: can resist 11-level wind, rainfall 50-100mm heavy rain; Visual: the flame height of the fire state is 3-4 meters, the flame is bright and stable; Economical: Low fuel costs.
"After the iteration of technology, we can produce hydrogen by capturing carbon dioxide in the air, and then electrolyzing water with filter electricity, and using carbon dioxide and hydrogen to synthesize low-carbon or zero-carbon methanol." Every ton of methanol produced consumes 1.375 tonnes of carbon dioxide from the air. The entire solution that achieves this carbon neutrality. As a supplier of green methanol technology, Yang Xueliang, senior vice president of Geely Holding Group, introduced.
It is reported that methanol is a globally recognized new clean and renewable energy, with safe and efficient, clean emissions, renewable characteristics, normal temperature and pressure for liquid, transportation and use is safe and convenient, also known as liquid "hydrogen". The world's first zero-carbon methanol lit the cauldron of the Asian Games, helping to create the first carbon-neutral Asian Games in history, and also demonstrating Zhejiang's innovation vitality and responsibility to promote sustainable development.
