The opening match of Beijing Winter Olympic Games – curling mixed doubles kicked off at the “ice cube” of the National Swimming Center on the evening of February 2.
Curling competition is the most demanding ice sport for the environment. During the competition, the temperature and hardness of the ice surface of the venue will be controlled strictly according to the requirements of the international competition, which will directly affect the ice surface viscosity. Otherwise, the ice surface will have a direct impact on the ice surface during the competition.
“Ice cube” is the largest curling venue in the history of the Winter Olympic Games. It is self-evident that it faces the technical challenge of venue temperature control.
The application of new building intelligent system platform technology (also known as group intelligence technology) has laid the foundation for the comprehensive intelligent management and flexible operation and maintenance of electromechanical equipment in venues. This technology is a national “13th five year plan” special project jointly developed by Tsinghua Tongfang Co.Ltd(600100) (600100, SH; yesterday’s closing price of 5.57 yuan / share) and Tsinghua University, which has played a role in the intelligent scene transformation from “Water Cube” to “ice cube”. By the end of 2021, the upgraded intelligent control platform will meet the needs of international ice makers and provide technical support for track ice making.
Tsinghua Tongfang Co.Ltd(600100) participated in many projects in this winter Olympics. Wang Zhiqiang, general manager of smart building and Park Company, told the daily economic news that as an enterprise, being able to guarantee the Winter Olympics is a contribution to the country, and income is not the focus of the guarantee work. The benchmark projects and industry standards formed in the guarantee work will be conducive to the company’s future business expansion.

first application of swarm intelligence technology
Do the spectators need to wrap themselves thick to watch a curling match? In the “ice cube”, the audience does not have to worry about the low indoor temperature. The application of swarm intelligence and other related advanced technologies can not only accurately ensure the temperature on the ice and meet the environmental needs of curling competition, but also create a comfortable viewing environment for the audience and create a wonderful space of “different temperatures in the same room”.
Specifically, the group intelligent system of the venue can automatically adjust according to the actual situation. Through the intelligent control platform, it can intelligently perceive and intelligently control the temperature and humidity environmental data of different areas such as ice, auditorium and office area, so as to ensure that the ice temperature of the track is always kept at – 8.5 and 10 at 1.5 meters above the ice under any heat load condition in the competition hall of the curling venue, Stand temperature 16 to 18.
The intelligent transformation project of the curling venue of the Winter Olympic Games is the first application of swarm intelligence technology in the venue, which was completed by Tsinghua Tongfang Co.Ltd(600100) in cooperation with Tsinghua University.
Most of the newly-built venues of the 2008 Olympic Games are different from those of Wang Zhiqiang’s participation in the 2008 Summer Olympic Games. The company is also based on the technical accumulation in the field of intelligent buildings and smart venues for many years, which fully demonstrates the key spirit of the scientific and technological Winter Olympics and contributes to the scientific and technological Winter Olympics, especially the “green winter Olympics”.
In addition to the aforementioned swarm intelligence technology and application system, Tsinghua Tongfang Co.Ltd(600100) there are a number of technologies and solutions that have been applied in the Winter Olympics.
For example, in Yanqing Winter Olympic Village, the “home of athletes”, the comprehensive energy management and control platform independently developed by Tsinghua Tongfang Co.Ltd(600100) has helped realize 100% clean energy supply here, and further improved the intelligence and efficiency of the energy network. Based on different energy consumption scenarios such as residential area, square area and operation area, the integrated energy management and control platform can realize intelligent optimization and regulation of large energy consumption equipment in the village, save building energy consumption, and integrate energy consumption data with digital twin technology to collect multi-dimensional energy consumption analysis indicators such as energy consumption and carbon emission data in one stop.
The new national speed skating Hall of the Winter Olympics has applied Tsinghua Tongfang Co.Ltd(600100) equipment monitoring and early warning platform. The platform can realize “perception, memory and thinking” of the operation of large HVAC equipment such as cooling units, air conditioning units and cooling towers in the museum.
In Shougang Park, through Tongfang Tede Techcon control management system, the air treatment unit, supply and exhaust fan, sewage system, indoor environment, cold source transmission and distribution and other subsystems in the park adopt optimal control and real-time monitoring, and the large electromechanical equipment in the park will operate more safely and stably.
At the same time, based on a large number of Internet of things, cloud computing and intelligent control and regulation algorithms, the park realizes data collection, statistics, analysis and comparison through Tongfang Techcon EMS energy management system, helps the reasonable matching of energy supply and demand in the park, and turns on the “switch” of Shougang park’s green and energy-saving operation mode.
benchmarking project is conducive to leveraging the market
In 2021, Tsinghua Tongfang Co.Ltd(600100) won the bid for the landscape lighting project of the Winter Olympic Games. “To ensure the Winter Olympics, the social benefits are higher than the economic benefits. We believe that the work done today, especially in these venues, will play a strong supporting role in the future.” Wang Zhiqiang said that the company participated in the intelligent construction of a series of venues for the Winter Olympic Games, enabled the intellectualization of traditional venues with new technologies, and also showed the world China’s achievements in green buildings.
The promotion of advanced technologies and solutions by demonstration projects is also a common market logic in the industry. Wang Zhiqiang introduced that the Benchmarking Project formed after its first application in the Winter Olympic Games will play a very good demonstration effect and help pry the market. In addition, he pointed out that the projects undertaken through the project will form another achievement beyond the project after the conclusion of the project, that is, a set of construction standards and operation and maintenance standards of the event venues, which will provide “industry standards” for the transformation and upgrading of stadiums and gymnasiums or new sports venues in the next step, and the importance of mastering standards for market competition is self-evident.
Taking the National Stadium “bird’s nest” as an example, in order to realize the intelligent upgrading from traditional buildings to stadiums and Gymnasiums in the digital era, Tsinghua Tongfang Co.Ltd(600100) has jointly built a digital twin platform with several enterprises to help the bird’s nest achieve low-carbon, energy conservation and consumption reduction, and provide intelligent security services at the same time.
The intelligent transformation of the bird’s nest is not the end. “As a world-class stadium that can accommodate 100000 spectators, in the future, the bird’s nest will serve as a model project for the transformation and upgrading of large venues and provide a standard reference for the intelligent construction of large venues. This solution can also be applied to large convention and exhibition centers. We hope to empower more projects through the experience of ‘bird’s nest’.”
Wang Zhiqiang positioned Tsinghua Tongfang Co.Ltd(600100) as a provider of intelligent infrastructure and information solutions in the Winter Olympics. It is understood that most of the Winter Olympics related projects come from the urban energy-saving intelligent industry direction in the company’s energy-saving and environmental protection business. Tsinghua Tongfang Co.Ltd(600100) said that it has formed many mature application scenarios, such as smart energy, smart transportation, smart building, smart government, smart security, smart education and so on.
