Computer control of 45 lighting operation modes in Olympic badminton venues

  On the 10th of this month, the "Good Luck Beijing" 2007 International Badminton Invitational Tournament started in the Gymnasium of Beijing University of Technology. The China team sent first-line players such as Lin Dan, Bao Chunlai, Xie Xingfang and Zhang Ning. In addition, the National Youth Team also handed in a list of 22 players. An invitational tournament without Olympic points, as for listing such a huge lineup?

  "Adapt to the venue!" Li Yongbo, head coach of the national badminton team, made clear the main tasks of this competition before the competition. As a venue for hosting badminton and rhythmic gymnastics in the 2008 Beijing Olympic Games, we certainly want to take this opportunity to feel it in advance.

  The steel dome spans 93 meters.

  The gymnasium of Beijing University of Technology is located in the campus of Beijing University of Technology on the East Fourth Ring Road in the shape of "flat badminton". When I walked into the gymnasium of Polytechnic University, the first feeling was as if I was immersed in a "blue ocean", with blue seats, blue fences and blue carpets.

  "The use of blue as the background tone is not a whim of our team, but a consideration based on the characteristics of badminton. The image landscape of badminton needs to highlight the word "elegance". Secondly, the rules of badminton require that the background is dark, and colors such as red and yellow cannot be used, so we finally chose blue. This also makes it easier for athletes to identify white badminton during the competition. " Xue Qiang, the image and landscape manager of the venue, explained that in the next rhythmic gymnastics competition, the venue will use more colorful colors such as yellow and pink.

  In the museum, if you look up a little, you will find that five circumferential steel cables and 56 radial steel tie rods at the top of the museum are woven into a fishnet in the air. This steel structure, which is about 150 meters long and 120 meters wide, has also created a record in the history of world architecture-the world’s largest span prestressed suspen-dome, with a maximum span of 93 meters.

  Clever design to avoid the influence of airflow

  Ji Xinpeng, a former Olympic champion and now the coach of the China badminton team, told the players: "Adapting to the venue is mainly to adapt to the romantic situation in the venue." During next year’s Olympic Games, Beijing is in the hot summer. In this museum which can accommodate more than 7,000 people, how to keep the indoor temperature at about 25 degrees Celsius without disturbing the competition? Can Beijing University of Technology Gymnasium do it? The "answer sheet" was handed in in advance in this invitational tournament, and national players such as Lin Dan expressed their satisfaction with the venue.

  Zhang Ailin went on to tell reporters that the gymnasium adopted the air-conditioning design of air supply under the auditorium, and more than 9,100 air outlet holes with a diameter of 13 cm were hidden under the seats. Because the air return opening was designed between the two floors of the auditorium, the vortex airflow was avoided, and the air-conditioning air supply was finally "broken into parts", which could completely meet the standard set by the International Badminton Federation that the air flow speed within 9 meters from the ground was not more than 0.2 m/s.

  45 kinds of lighting operation modes

  "The conditions of the venue are quite good, except that the lighting is a little dazzling. It would be very good if the lighting could be adjusted again." Gao Kun, who is already the mixed doubles champion of Sydney Olympic Games and Athens Olympic Games, put forward his own little suggestions for this newly completed Olympic stadium after his personal experience in this invitational tournament.

  As a professional badminton gymnasium, lighting is an important evaluation index. Wang Puen, the lighting project manager of the venue, said, "One of the most important features of the lighting facilities of the Beijing University of Technology Gymnasium is that the light bulbs in the whole competition venue can be adjusted up and down, and the lighting system is intelligently controlled. After setting, it is adjusted by computer instead of manual manipulation."

  In view of the fact that players occasionally feel strong side light when they compete in the venue, Wang Puen said that it can be solved by adjusting the position and illumination angle of the light. The whole system is divided into 45 operation modes according to the needs of the competition.

  ■ Post-game use

  Will become an important cultural heritage of the school

  In Beijing, there are six Olympic venues located in university campuses. Are they different from other Olympic venues? According to Zhang Ailin, vice president of Beijing University of Technology, at the beginning of designing the gymnasium, Beijing University of Technology re-planned the whole campus to achieve harmony and beauty among people, nature, architecture and environment.

  "Considering that Beijing University of Technology is still short of stadiums and student activity centers, the completion of this Olympic stadium has a prominent feature-combining sports and education. After the Beijing Olympic Games, it will become a heavy cultural heritage, staying in the campus with a strong university atmosphere and serving the teachers and students." Zhang Ailin said.

  Of course, as the only Olympic venue in the southeast of Beijing, the post-games function of Beijing University of Technology Gymnasium is not only that, it will also be opened to the surrounding residents as a community fitness and cultural and sports activity center in this area. At that time, there will be basketball, volleyball, table tennis and other training venues in the gymnasium, as well as dance, vocal music and band rehearsal halls. In addition, it also includes a venue for various reports, group training, skills training, and exhibitions of cultural and scientific works.

  ■ Volunteers in the stadium

  Self-designed chest logo only serves better.

  In the previous "Good Luck Beijing" test competition, we met some volunteers who wore the "smiley face" logo on their chests. However, in this International Badminton Invitational Tournament, we saw "smiling faces", "cute cars" and "dialogue boxes in comic books" … Every volunteer in the Badminton Hall of Beijing University of Technology has a round logo on his chest.

  Ren Wei, a volunteer at the Badminton Hall of Beijing University of Technology, said, "This way, when you pass by any volunteer, you can immediately know which position he comes from. The little sign on their chest says everything." According to Ren Wei, there are a total of 674 volunteers in the Beijing University of Technology Stadium, distributed in 18 business openings, and the logo of each business is different. For example, the audience service volunteers wear a "smiling face", the language service volunteers wear a "dialog box" and the catering volunteers wear a "knife and fork". In short, each pattern can easily remind people of its meaning.

  These volunteer logos are the first of the Olympic venues that have hosted the "Good Luck Beijing" series of test competitions, and the designer Ren Wei admits that such inspiration comes from the "smiling faces" of audience service volunteers. "Since they can have a’ smiling face’, do students in other business areas also have their own logos, so that others can know which position they are in when they see the logos?"

  ■ Olympic preparations

  Gao Kun: Who said that I am old and still want to play women’s singles?

  Gao Kun lost. In the mixed doubles final of the "Good Luck Beijing" test competition, she and her partner Zheng Bo lost 2-0 to her teammates Xie Zhongbo and Zhang Yawen. Laughing, she didn’t stop her bright smile because she missed the championship. From the first day of the competition, Gao Kun’s purpose was very clear. "This is just a test match, or it is mainly to adapt to the venue."

  Although it is only an invitational tournament, it can be seen that the training rhythm of Gao Kun is basically the "Olympic rhythm". In the previous Macau Open, Gao Kun gave up the mixed doubles competition and focused on women’s doubles. In this competition, she abstained in the women’s doubles competition and fully prepared for the mixed doubles competition, which inevitably makes people wonder, which is the main event of Gao Kun, the women’s doubles or the mixed doubles? "Some time ago, because the women’s doubles points fell, I focused on women’s doubles. This competition is mainly to adapt to the venues, and we still have to make more preparations for the future points competition. I can play both women’s doubles and mixed doubles. " I see! Unexpectedly, Gao Kun then added: "If the team allows, I want to play three more events and also play the women’s singles."

  Gao Kun already has the glory of champion in Sydney Olympic Games and Athens Olympic Games. Although it is not an exaggeration to be called "veteran" by reporters, Gao Kun protested loudly: "Who says I am old, I am quite young!" Four years will soon become history again. Different from the previous two Olympic Games, there is Gao Kun’s mixed doubles partner. When it comes to Zheng Bo, who is three years younger than herself, she joked again: "He, if you want to fight, you have to scold. Of course, encouragement cannot be less. " Then, Gao Kun spoke his mind, "Zheng Bo’s skill is good. He has played doubles before, so he is basically satisfied with the cooperation. Although we haven’t been partners for a long time, I think there should still be room for improvement on the ball road, and I will give some technical guidance and help when necessary. There is also the need to rely on the two of us to slowly run in. "

  ■ Reporter’s Notes

  Marriage between Olympic Games and Universities

  I don’t know when it started, but it became popular to integrate large-scale sports venues with domestic universities. But this is definitely a good phenomenon. In July this year, the volleyball final of the Six Cities Games held in Wuhan was held in the Optics Valley Gymnasium of Huazhong University of Science and Technology.

  Would colleges and universities build such high-standard venues if it weren’t for the upcoming large-scale events? Because the construction of a high-standard venue is not just a house built with bricks, it is related to the initial demolition, design, capital and other aspects.

  After the games, these venues will basically become sports venues for teachers and students of the school. Can you exercise and learn about sports in the venues used by professional athletes and even the world’s top players? Is that the same feeling as before? I remember a volleyball fan described to me after stepping on the floor of the volleyball final venue of the Sixth City Games: "It feels really different, and now I don’t want to graduate, because only in this way can I play more games here."

  Zhang Ailin, Vice President of Beijing University of Technology, put it well. As a heavy cultural heritage, this venue will become one of the landmark buildings of Beijing University of Technology. Suppose you have such a stadium in your present or former school, I believe that even if you don’t like sports, you will definitely talk about your university campus without it!
