Advanced technologies in the Beijing Olympic Games

The organization of the Olympics in previous periods is a process of focusing on the achievement of scientific achievements - the latest technology, the Beijing Olympics this time is not an exception.

With the application of advanced science and technology achievements in areas such as construction, communication, traffic ., the Beijing Olympics will become more and more attractive.

The stadium is not structured

Beijing has built a total of 12 stadiums for the 29th Olympics. A series of new scientific and technological achievements have been used in building and presenting the concept of "Olympics" perfectly. science and technology".

For example, the National "Bird's Nest" stadium , the overall steel structure aperture is about 340 meters wide, 68 meters high, and the total weight is 42 thousand tons. But the stadium with such a heavy steel structure did not have a pillar, completely supported by a grid-shaped structure made of steel plates.

The person in charge of the construction project of Ly Cuu Lam National Stadium said that the creation of this architecture is due to the Q460E steel material that China has researched and exploited by itself. The strength of this steel material is more than three times that of ordinary steel material, on average per square millimeter of steel with a bearing capacity of 46kg.

As the National Stadium can welcome more than 90 thousand people, to create a nice and comfortable environment for the audience when watching the competition, the science and technology officers have repeatedly conducted simulations and feces. equal to the computer for the temperature, air circulation situation of the National Stadium, and calculate the temperature and the speed of air circulation that the audience of each area can feel. Deputy General Director of the National Stadium Limited Company Zhang Hang Loi said, when the Olympic games took place, any audience seated upstairs or downstairs, whatever the usual seat is a VIP seat They can enjoy natural light and wind in a relatively comfortable way.

Energy saving

In addition to the overall design, the science and technology content of the details in the stadium also cannot be underestimated. For example, a high-quality monitor placed in the Olympic Center's control room has used advanced laser-based display technology.

Wang Vu, curator of the Chinese Academy of Photovoltaic Research in charge of the project, said that, compared to traditional television sets, the color of the laser beam screen looks more and more realistic, Moreover, its energy consumption is only 1/4 of the energy consumption of traditional television sets. "The current third-generation monitor can only make human vision visible to about 30% of all inherent colors. Parallel to the new light source, where laser is applied to the work. screen technology, humanity will be able to feel the majority of colors , " he said.

Another proof of the energy-saving and environmental-conscious sense is that the self-researched Chinese glass walls can absorb the sun, which are now installed outside many yards. The gym serves the Beijing Olympics to provide clean energy for those stadiums. Besides, 15 stadiums have installed rainwater recovery and utilization system with a high level, which can recover 1 million cubic meters of rain water every year.

Advanced security equipment

To ensure the competitions of the Beijing Olympics are high-performance, convenient and safe, the security testing equipment of the stadiums all have applied cutting-edge science and technology.

Chief Technology Officer Beijing Olympic Organizing Committee Yangyi Xuan said the new technologies applied in the security system for the Beijing Olympics are primarily expressed in the application of advanced, reliable identification technology. dependable and pragmatic. This technology is mainly used in the opening ceremony, closing ceremony and major stadiums, in order to enhance the function of counterfeiting, and at the same time, it is convenient for the audience to quickly pass through the security checkpoint. security, avoid congestion.

The image recognition technology introduced by Mr. Duong Nghia Xuan above is also called "identification technology through human face ". As one of the bio-identification technologies, if compared to fingerprint recognition technology, this technology has the most unique and stable safety. When the audience passes through the security check, this identification system only needs 0.01 seconds to capture the detailed features of the face and accurately identify the identity of the passerby. During the Olympic Games, information of about 1 billion people will be included in the Identity System Data Warehouse through the faces of Beijing Olympic stadiums.

Sustainable achievement

During the Beijing Olympics in 2008, a large number of athletes and the public came to see the Olympic Games will share the convenience brought about by advanced science and technology. China's Minister of Science and Technology, Wanjiang, also expressed that the science and technology achievements are not only reflected in the Olympic Games, but also that they can continue to popularize applications after the Olympic Games, making science technology goes deep into people's lives and better serves economic development.

According to Mr. Van, after the end of the Olympic Games, cars using clean energy including mixed energy . will be popularized in many cities. Waste water treatment technology and treatment of waste water, especially those applied at each stadium, will be applied to building apartments, to provide water saving and use services. Water, while China's third-generation mobile communication technology standard (TD-SCDMA) will deploy experiments in the country after widespread application at the Beijing Olympics.
