The Beijing Winter Olympics arrived as promised. "Science and technology Winter Olympics" is one of the main features of the Beijing Winter Olympics. Many eye-catching "black technologies" appeared in this event, including the figure of "smart" made in Ningbo.
Ningbo Dafeng
light the main torch of the Winter Olympic Games with green technology
Last night, the main torch of the 24th Winter Olympic Games was lit at the Beijing National Stadium (Bird's Nest).
The main torch system of this winter Olympic Games was created by Zhejiang Dafeng Industrial Co.Ltd(603081) in Yuyao. "The use and conception of the main torch of the Beijing Winter Olympic Games is groundbreaking. The creative team focuses on science and technology, ingenious and aesthetic ideas, makes bold innovation and careful experiments, and finally transforms the idea of sudden whim into a magical and aesthetic reality." Feng Jialong, chief creative officer of Dafeng, said.
It is reported that the ground device system of the main flare consists of LED chassis, auxiliary turnover and lifting device of the main flare and step lifting device. The main torch is developed and designed in accordance with the concept of green and sustainable development. The fuel of the main torch uses hydrogen as the fuel to ensure that it can be used in extremely cold weather and can resist wind of Grade 10. All the ground devices of the main flare are designed and manufactured with environmental protection materials and processes. The driving system of the main torch overturning and lifting device is composed of four sets of huge and precise rack mechanisms. Under the precise control of Dafeng's unique control system, the rack with a length of 9 meters can rise and fall at different heights and rotate at different angles to complete the complex curve movement. With the ingenuity of four or two kilos, the main torch can be flexibly raised by 8 meters in a beautiful arc, and then the main torch can be transported to the high altitude.
The step lifting device is designed with an ingenious turnover compensation device, so that the 24 steps symbolizing the Chinese 24 solar terms culture can always automatically maintain the level and the height difference is consistent. Even if the steps are in motion, the torch bearer can pick up the steps.
As one of the key participating units in the construction project of this winter Olympic Games, Dafeng not only provided the core device system for the core link of the opening ceremony, but also deeply participated in many topics of the national key R & D plan project of "science and technology Winter Olympic Games".
Dafeng has installed "fluorescent sticks" on 8000 seats in the National Stadium and Wukesong Sports Center. Based on wireless group control technology and active positioning technology, these "fluorescent sticks" will present different atmosphere effects such as urban animation, happy pandas, fireworks, snowflakes and participating national flags according to the content created by the staff in the cloud.
In addition, Dafeng also provided the seating system of three-quarters of the venues with auditorium for the Beijing Winter Olympic Games. The seat system is not only green and environment-friendly, but also can realize the transformation of venue functions through intelligent sports changes, so as to maximize the use efficiency of venues.
\u3000\u3000 Ningbo Orient Wires & Cables Co.Ltd(603606)
work hard for the "green power" transmission of the Winter Olympics
On January 17, foreign ministry spokesman Zhao Lijian introduced the concept of "Green Olympics" in response to a reporter's question. He said that 26 venues in the three competition areas of the Beijing Winter Olympic Games will realize 100% green power supply for the first time, which makes the Zhangbei flexible DC power grid project enter people's vision again.
As the world's first major project to realize the construction of flexible DC power grid, the project is the flexible DC project with the highest voltage level and the largest transmission capacity in the world. As a supplier of 535kv flexible and direct cables for the project, Ningbo Ningbo Orient Wires & Cables Co.Ltd(603606) has worked hard for the project for four years and overcome a number of key technical problems. It has not only successfully contributed to this world-class sports event, but also provided a "Ningbo scheme" for large-capacity and long-distance power transmission in the future.
"Zhangbei flexible DC power grid project has created 12 world firsts in the R & D and application of key equipment. One of the DC cables with the highest voltage level and maximum transmission capacity in the world is developed and manufactured by our company." Chen Lei, technical director of Ningbo Orient Wires & Cables Co.Ltd(603606) marine innovation center.
"This time the cable section reached 3000 square millimeters." Chen Lei said that the design and manufacture of large cross-section DC cable is also one of the technical difficulties of high-voltage DC cable. "Through the optimization of cable special-shaped conductor stranding, we increased the filling coefficient of this large cross-section conductor from 89% to 97%, ensured the stability of cable quality, and finally realized the demonstration application in Zhangbei flexible DC power grid project."
Guodian Ningbo Hydrogen Energy Research Institute
150 hydrogen buses serve the Winter Olympics
At 8:00 last night, at the opening ceremony of the Beijing Winter Olympic Games, Gong Xin and his colleagues were carefully conducting a "physical examination" for the returning hydrogen bus in the closed-loop parking lot of Yanqing stadium of the Beijing Winter Olympic Games.
On December 13 last year, the hydrogen fuel cell power system buses developed and manufactured by Ningbo were successively transported to the Winter Olympic Games. At present, there are about 150 "made in Ningbo" hydrogen buses serving the Winter Olympic Games. These white and green hydrogen buses are 11 meter long tour buses, carrying 46 people. The vehicles are equipped with imported airbags, luxury seats and ultra-low temperature heat pump cooling and heating air conditioning, which are very comfortable to ride. Compared with electric buses, hydrogen fuel buses are not only environmentally friendly, but also have the advantages of fast energy supply, less time and stable operation under the condition of - 20.
"These hydrogen buses have a design speed of 100 kilometers per hour and a pure hydrogen endurance of about 450 kilometers." Chen Ping, chairman of Ningbo Hydrogen Energy Research Institute of state power investment, told reporters that from the current operation situation, these vehicles can better adapt to the low temperature, steep slope and other road conditions in the Winter Olympic Games area.
neighbor network technology
technical support for nucleic acid detection of Winter Olympic Games
Chaoyang District, one of the main venues of the Beijing Winter Olympics, will start the nucleic acid detection and registration of the spectators. Haishu enterprise - Linjia Network Technology Co., Ltd. provides all-round technical support for this work with the self-developed forage QR code system.
The Beijing Winter Olympics involves a large number of personnel and a large amount of testing, and has high requirements for technology and efficiency. Previously, Chaoyang District has repeatedly debugged the current mainstream nucleic acid detection and registration tool, and the effect is not ideal. At the recommendation of a local cooperative enterprise in Beijing, the "forage QR code" of neighbor network technology entered each other's vision.
After understanding each other's needs and use scenarios, within two days, neighbor network technology built a system suitable for nucleic acid registration needs, allowing residents to fill in their own identity information and conduct nucleic acid detection based on the generated serial number and QR code.
"After testing, compared with other technical products, the registration efficiency of 'forage QR code' is at least five times higher, and the residents have a better sense of experience." The relevant person in charge of next door network technology company said. After several rounds of high-intensity testing by about 100000 people every day, "forage QR code" stands out with excellent technology and has become one of the technical support units for nucleic acid detection in Beijing Winter Olympic Games.
