The "Music Highway" on the Asia Snow Highway. Xinhua News Agency reported that the 9th Asian Winter Conference will be held in Harbin soon. In order to welcome Chinese and foreign athletes and tourists, the local government has created a full "atmosphere" through technological empowerment. Zhang Shaojun, director of the Engineering Department of the Yaxue Highway Renovation and Expansion Project Office of the Heilongjiang Provincial Highway Construction Center, said that the ability to "sing" on the road is to turn the selected music into a music road simulation and simulation production file, and then compile the corresponding spacing according to different melodies. Size, and etched on the road surface, when the car passes at a certain speed, it produces wonderful music through resonance.

On the 3rd, the 9th Asian Winter Games torch relay event was held in Harbin. The torch design uses transparent ice crystals with a gradient snowflake, and the inner core with a blending effect of ice and fire after ignition, which looks full of technology, highlighting the vitality and vitality of "Ice City". It is understood that this is a transparent special functional material screened by the lightweight functional material team of Harbin Engineering University.

"To realize the design concept, the selection and functional enhancement of shell materials are extremely critical." Sun Gaohui, a professor at the School of Materials Science and Chemical Engineering of Harbin Engineering University, said that it is necessary to ensure transparency and tolerance. Technical requirements such as high and low temperature alternation and flame retardant also take into account the feasibility and cost saving of complex structures and gradient effect forming. After continuous optimization, the overall stability of the torch is ultimately ensured.

On the 4th, the 9th Asian Winter Games curling competition started at the Curling Hall in the Bungalow District of Harbin, and shouts and cheers resounded throughout the hall. It is understood that adhering to the "green, sharing, openness and integrity" competition hosting concept, all five venues of the 2025 Harbin Asian Winter Games ice project have been upgraded and renovated using the original venues and facilities.

Zhao Guannan, the operation and maintenance manager of the venue facilities of the curling hall operation team in the bungalow area, introduced that the curling hall fully considers language acoustics, geometric acoustics, and building acoustic systems engineering during construction, and specializes in the construction of the curling hall. Two independent sound reinforcement systems, centralized sound reinforcement system and dispersed sound reinforcement system, were designed and built to ensure the event, successfully eliminating the audience's echo, and the sound produced by the sound is uniform and clear, demonstrating China's "intelligent" manufacturing.

Technical means also play an important role in the competition judgment process. Taking the short track speed skating competition as an example, the athletes were speeding at a speed of more than 50 km/h on a single lap track of 111.12 meters. In order to avoid possible mistakes in manual circle recording, a circle recording system came into being.

Shan Baohai, a professor at Harbin Sports University, introduced that his team has been serving the China Skating Association and large-scale domestic and foreign events for many years, and has rich technical reserves. This time, the team members are full of confidence in the short track speed skating competition of the Asian Winter Games.

The short track speed skating competition video playback system independently developed by my country not only can record every detail of the competition in detail, but also innovatively launched the "Straight + Tracking" dual-screen display function, which greatly improves the referee's judgment efficiency. . Dan Baohai said that this technological innovation plays an important role in shortening the referee's long viewing time and accurately making penalty during the competition.

Most technological empowerment is inseparable from the support of electricity. When entering the Asia Winter Conference Power Supply General Headquarters, the real-life 3D effect of Harbin International Exhibition and Sports Center is vividly displayed on the screen. With the operation of the staff, the large screen switches to the venue, and information such as the status of various power supply and consumption equipment, the direction of transmission and distribution lines is clear at a glance.

The support of technology is behind the operation of Xinhua News Agency. In order to ensure the efficient and reliable operation of comprehensive command during the Asian Winter Games, the State Grid Heilongjiang Power Construction Digital Power Supply Command Platform has deeply integrated business data, connected to more than 14 sets of power grid business systems, and monitored 52 substations involved in the Asian Winter Games power supply in real time. The power data of 158 transmission lines and 435 distribution stations and other facilities provide a steady stream of momentum for safety guarantees, emergency commands, and information display during the event.
