The upcoming 2008 Beijing Olympic Games put forward the concept of science and technology Olympics for the first time. Beijing City has changed into a wireless city. The weather forecast has entered the digital age and supported the Olympic Games with advanced digital technology. The Olympic achievements have benefited the society and become a highlight of the Beijing Olympic Games.
Wireless signal to create a media feast
When the 2008 Beijing Olympic Games was held, there were 10,000 athletes, more than 10,000 sports officials, coaches and referees, more than 20,000 media reporters, 50,000 volunteers, and tens of thousands of live visitors. Nearly one million, the number of global TV viewers and Internet users can reach billions. The current Olympic Games is large in scale and involves a wide range of users. Users have more demand for mobile communications than in previous years, and the requirements are higher.
The inspiration of the experts' research was from a moment. When the reporters walked back and forth with the big bag of interview equipment, an idea began to emerge: if the reporters can shoot and pass, the wireless network built by China Mobile anytime, anywhere. It will be extremely convenient to pass the photos they have written and the photos they have taken back to the rear editorial department.
After repeated exploration and research, this idea has become a rich scene: after the morning Olympics reporters get up, they use the wireless mobile communication mobile phone with intercom function and positioning function to book a day through the China Mobile Media Service Portal. The interview object, the service portal sends the reporter's reservation information to the mobile phone of the interviewee, and gives advance notice and reservation to both parties at the time; on the way to the competition venue, the mobile navigation function will tell the reporter the venue to go through the Mobile Phone Screen. What place, road conditions and weather, where the parking space is, where the partner is waiting; after arriving at the competition venue, the reporter can watch the game on the other side of the game at any time by interviewing and find the location of other partners. connection. Through the wireless communication technology, the reporter can receive the moment after writing the manuscript and grabbing the wonderful video image, and the video terminal of the rear editing department can receive it.
It is like describing a future illusion after a few years, but the Beijing Olympics shouted confidently to the world, which has become a reality.
Weather forecast into the digital age
In December 2006, the opening ceremony of the 15th Asian Games was held in Doha, Qatar. The three-hour opening ceremony was extremely luxurious. The Qatari people proudly displayed this mysterious desert oasis, but also through their own The vision reproduces the splendid Asian culture. However, an unexpected rain has brought some regrets to the opening ceremony of the Doha Asian Games.
People can't help but worry: Will it rain on August 8th in Beijing?
In order to let Tianzhu people wish, China has successfully launched Fengyun-2, Fengyun-3 and other meteorological satellites. Their purpose is to comprehensively forecast the weather during the Beijing Olympics, especially the large-scale events and important events such as the opening and closing ceremonies of the Olympic Games. The weather changes at the time provide accurate and timely services for the Beijing Olympic meteorological security system.
According to reports, the Fengyun-3 satellite is a polar-orbiting satellite that scans the world twice a day, each with a width of 2,900 kilometers, which is global. With up to 11 payloads and more than 90 detection channels on the Fengyun 3, you can detect any meteorological environment regardless of day or night. Fengyun No. 3 carries a vertical detector, which can form a stereoscopic color image over a range of more than 30 kilometers above the ground, thus greatly enhancing the refinement and accuracy of weather forecasting.
The Olympic weather forecast will no longer be sloppy, but it will clearly indicate whether there is rain, specifically when it is a few minutes, and specific to an Olympic venue. In addition to providing fine services for the Beijing Olympics, the two satellites will also make China's digital weather forecast possible.
Water Cube realizes new breakthrough in LED
The Beijing night sky during the Olympics, the radiant bird's nest and the dreamy water cube will attract the attention of the whole world, and their so fascinating mystery is due to the new technological breakthrough realized by LED lighting technology under precise control.
The water cube uses the light-transmitting illumination method in the cavity. The successful realization of this technology will also be the LED landscape lighting solution of the largest membrane structure in the world. Adopting a single 1W high-power LED light source, the light source has long life, easy integration, fast response, environmental protection, high energy saving, light distribution, easy control, and rich colors.
The outer wall of the Water Cube uses LED energy-saving lighting, with red, blue and green as the base color, and the lighting changes are controlled by the automation system.
In addition, LED can also achieve energy saving and environmental protection. Compared with fluorescent lamps, the energy saving is at least 60%, mercury-free, waste-free, and UV-free. A series of technological breakthroughs will play an important role in the development of the LED industry.
