On September 23, 2023, the opening ceremony of the Hangzhou Asian Games was not only a sporting feast but also a feast of technological miracles and creativity. In this highly anticipated event, Dafeng's unprecedented technological feat led the audience on an imaginative journey through the "Qianjiang Tide," showcasing China's spirit of innovation and technological strength.

Like the surging Qianjiang River, the main torch tower is displayed with stunning dynamism. Mechanical art showcases strength and resilience, while curved lines convey softness and flexibility, symbolizing the harmony of strength and softness in Chinese philosophy.

Traditional torches are only static, but how can they embody the vitality and power of the "Qianjiang Tides"? The Asian Games embody the charm of sports, and the dynamic "Qianjiang Tides" main torch tower perfectly embodies this concept. Dafeng's creative and R&D teams not only make the torch move but also move with such grace.

To this end, Dafeng designed a bionic mechanical skeleton system, dynamic decoration system, combustion system, and intelligent brain control system for the Torch Tower, creating an unprecedented technological marvel.

Bionic mechanical skeletal system

Inspired by bionic principles, Dafeng designed the torch tower's skeletal system. The torch tower consists of 19 uniquely shaped columns, forming a wave-like appearance. These 19 columns symbolize the 19th Asian Games and represent the long history of the Games. The interior of the torch tower uses a dynamic structure that can take two forms: first, when the "wave" curls, it is about 10 meters tall, resembling a traditional Chinese auspicious cloud; second, when the "wave" unfolds, it is about 19 meters tall, shaped like the surging tides of the Qianjiang River, ultimately igniting the torch. The largest skeleton uses a 16-segment flexible segmented design to achieve perfect arcs and straight line transitions, smooth and elegant. The design is precise, with the skeleton gradually reduced to achieve the ideal effect. To ensure millimeter-level precise movement, the main drive system uses a precision ball screw structure, along with a mirror-symmetrical skeletal system to eliminate displacement, sway, and deflection forces. Additionally, advanced CNC technology is applied to reduce energy consumption and improve operating speed and smoothness. To ensure the performance is free from interference, the drive system features redundant designs, allowing backup motors to continue running in case of main motor failure.

Dynamic decoration system

Combustion system

The combustion system includes fuel pumping, multi-nozzle ignition, and control systems. Dafeng uses dual-nozzle ignition technology to ensure high safety and waterproofing, so even in level 10 winds and heavy rain, the torch can burn without extinguishing. At the same time, Dafeng is equipped with a remote fuel pumping system to ensure fuel can be safely and stably delivered through high-strength custom pipelines. The entire system adopts a primary and backup mode to guarantee system reliability. This system can also achieve multiple combinations of ignition effects. In terms of fuel, Dafeng partnered with Geely to use zero-carbon methanol, fully embodying the "green" hosting philosophy of the Hangzhou Asian Games.

The bionic mechanical skeletal system, dynamic decoration system, and combustion system together form the Torch Tower's lively, elegant, and sturdy appearance. To have such an appearance, it also requires a smart brain.

The beauty of the "Qianjiang Tides" lies not only in its exterior design and green energy savings, but also in its powerful "brain." This "brain" is Dafeng's independently developed intelligent brain control system. As the nervous center of the torch tower, this system can simultaneously control the operation of four major systems: mechanical, combustion, lighting, and decoration. By sharing and communicating data with each system, it precisely directs the operation of each system. Moreover, it can collect and analyze various data in real time, such as temperature, humidity, and other environmental safety data, ensuring all equipment is in optimal condition.

To ensure absolute safety for the "brain" to operate, Dafeng also adopted a safety-axis controller, raising the overall security level of the "brain" to SIL3 level. At the same time, the master-standby control systems are integrated into a single operating system, which is independent yet compatible. If the master system encounters problems, the backup system can immediately take over, and the entire switching process is completed automatically without manual intervention, greatly improving system reliability.

Another major highlight of the "Qianjiang Tide" is digital twins. In Dafeng's "hands," digital twin technology is like magic; it not only improves the design, operation, and maintenance efficiency of torch towers, but also enhances overall safety and innovation, greatly reducing the difficulty of remote adjustment and troubleshooting, and minimizing downtime. By closely integrating with automation systems and empowered by digital twins, the intelligent brain control system becomes smarter and more intelligent.

The digital torchbearers, pioneered at the Hangzhou Asian Games, ignited the enthusiasm of hundreds of millions to participate in the Games. Dafeng's exploration and innovation brought together hundreds of millions of digital torchbearers at the Hangzhou Olympic Sports Center Stadium, where they together with the final torchbearers on site ignited and activated the Dafeng Smart Brain Control System. The mechanical, lighting, decoration, and combustion systems worked together seamlessly, with 19 torch poles surging like a tide and growing gracefully. Blazing flames erupted from 19 tides, reigniting the flame waves that ignited the torch tower. The roaring "Qianjiang Tidal Surge" torch tower ignited vibrant life, thrilled the world, and awakened the passion in hundreds of millions of hearts, pushing the atmosphere of the evening to its peak. The charm of combining digital and physical materials perfectly blended the real and virtual worlds.

The lighting of the "Qianjiang Tidal Wave" torch tower is not only the prelude to the Asian Games but also the beginning of Dafeng's comprehensive service for the Hangzhou Asian Games. In addition to the torch tower, Dafeng has provided a series of high-tech systems for the Olympic Sports Center Stadium, including lighting, sound, and large screens, fully presenting the exciting Asian Games events. The photo booth in front of the podium is built to high standards, flat, quiet, and sturdy. Adjustable high-transparency PC board railings and a safe, silent rail system not only enhance the viewing experience for VIPs but also protect photographers' safety. The Hangzhou Esports Center features Dafeng's carefully crafted ten intelligent venue systems. Dafeng provides core equipment and comprehensive solutions for 36 venues for this Asian Games, offers comprehensive operation management services for the Hangzhou Asian Games Museum, and offers rail vehicle interior solutions for all metro lines and airport express lines in Hangzhou. The Dafeng Art Troupe appeared at the opening ceremony of the Hangzhou Asian Games, performing in two major programs: the music, poetry, and painting "Spring Breeze Greens the South Bank Again" and the song and dance "Heart and Hand Connected" (accompanying dance). Dafeng is fully prepared, looking forward to creating brilliance for the athletes and presenting a spectacular feast for hundreds of millions of spectators. Dafeng has already become an indispensable technological force at the Hangzhou Asian Games.

At this opening ceremony, the fusion of machinery and intelligent brains presented a mesmerizing visual feast, showcasing China's innovation and creativity to the world. This "Qianjiang Tidal Wave" torch tower will forever remain in the memory of the Hangzhou Asian Games and will inspire the world to continuously push the boundaries of technology and creativity.
