China News Finance, January 6 (Reporter Zhang Xu) On January 6, a "Fuxing" train with ice and snow blue as the main color slowly departed from Platform 1 of Beijing Qinghe Station.
The aerodynamically streamlined body is decorated with fluttering snowflakes and silhouettes of ice and snow athletes, all of which are related to the Winter Olympics.
"This Fuxing Intelligent EMU train for the Winter Olympics is full of Olympic features from the two dimensions of humanity and service elements. It is tailor-made for the Beijing Winter Olympics." Jia Lu, deputy director of the Vehicle Department of Beijing Bureau Group Corporation, told reporters The car is equipped with the world’s first high-speed rail 5G ultra-high-definition studio, which can realize guest interviews, full-car mobile live reports, provide virtual production, multi-party connections and other services for large screens and small screens, realizing long-term, high-speed mobile programming Stable transmission.

350 kilometers per hour self-driving train
Mo Zhisong, director of the Communication and Signaling Department of the Ministry of Industry and Electricity of China National Railway Group, told reporters that thanks to the ATO automatic driving system, the Beijing-Zhangjiakou High-speed Railway has achieved automatic driving at a speed of 350 kilometers per hour for the first time in the world. With functions such as parking and automatic door control, two hundred percent of parking accuracy and train operation punctuality have been achieved since operation.
"The screen door and the train door are aligned accurately, making it easier for passengers to get on and off the train. Our previous requirement was to control the error within ±50 cm. Now through actual measurement, the error is concentrated in ±10 cm to 20 cm."
Stop accurately, but stop firmly.
After model construction, data analysis, and index optimization, the train ensures smoothness and comfort during deceleration and braking.
"The industry-recognized indicator is 0.75 meters per cubic second. Even if this indicator is reached, it is more comfortable and stable. After actual measurement, our automatic driving is within 0.4 meters per cubic second, and the performance is far better than the industry's stability indicators."

The automatic driving system can not only sense the operating status, but also calculate the optimal control curve to achieve energy saving and emission reduction.
"Compared with the driver's manual driving, the energy saving from Zhangjiakou to Beijing can be 7%. Moreover, the energy-saving control algorithm has room for continuous optimization and functional iteration. Our goal is to achieve energy saving of 10% to 15%, which is as green as the Beijing Winter Olympics. The concepts of the Olympics and the Hi-tech Olympics are very consistent." Mo Zhisong said.
Reduce weight and improve efficiency, saving 1.8 million kilowatt-hours of electricity a year
The Winter Olympics train connects the three major stadiums of Beijing, Yanqing and Chongli. During the Winter Olympics, how to ensure that the train runs smoothly at high speed in the snow and ice environment is a difficult problem.
Zhu Yan, deputy director of the Engineering Research Center of CRRC Changchun, told reporters that the train uses high-cold EMUs, which can adapt to the low temperature environment of minus 40 degrees Celsius.
"The comprehensive application of low-temperature sealing technology, anti-icing and snow technology, anti-impact technology, condensate disposal technology, and thermal insulation technology makes the train look like a'big padded jacket' that can adapt to very low ambient temperatures."
With the "big padded jacket", the weight of the train has been greatly reduced.
"The weight of the whole train is about 20 tons less than the previous generation model. The body adopts environmentally friendly degradable materials, and the material recovery rate reaches more than 75%, and the degradability rate reaches 50%."

The clever design of the train is also reflected in the front of the train.
Zhu Yan introduced that in the design process of the head of the intelligent EMU, considering the aerodynamic performance, the eagle tenon shape was finally selected from more than 40 schemes, which can significantly reduce energy consumption while reducing resistance.
"The aerodynamic performance of this model is the best, and the drag coefficient is the smallest; the body adopts a smooth and streamlined design, so that the running resistance of the entire train can be reduced by 7.9% compared with the previous generation model, and the overall energy consumption can be reduced by more than 10%. After calculation, it can save about 1.8 million kilowatt-hours of electricity in one year of operation."
Humanity design, manifest everywhere
Starting from the cab, the reporter saw that there are ski equipment storage cabinets at both ends of carriages 1, 4, and 8 of the EMU, for ski lovers to store skis and other equipment; carriage 4 is also equipped with a wheelchair storage area, which is barrier-free. Toilets and platform compensators are convenient for wheelchair storage and passage without barriers, and meet the needs of the Winter Paralympics.

On the basis of maintaining the standard configuration of the Fuxing Intelligent EMU intelligent services, intelligent operation and maintenance and other functions, the new Olympic version of the Fuxing Intelligent EMU adds intelligent driving functions, and targeted services for the Winter Olympics and the Winter Paralympics. Optimize the design.
The train provides Chinese and English broadcasting and information display. The intelligent interactive terminal for business passengers provides services such as the high-speed rail entertainment center, wireless projection, vehicle function introduction, and vehicle operation information query. During the Winter Olympics, it can also provide live events.
The No. 5 carriage of the EMU is a multi-functional carriage with a media work area, 12 desks, international sockets, small sliding tables and other facilities, which can seat 48 people and provide an office environment for media personnel; at the same time, it can be realized 5G HD event live broadcast, with 6 channels 4K live broadcast capability; radioactive blue lights are used on the top of the carriage, which fits the ice and snow theme of the Winter Olympics; the open dining bar area of carriage 5 is mainly based on ice blue and is called " 2022 Beijing Olympic Blue" reflects the fighting spirit of the Winter Olympics athletes.

Here, passengers can also buy licensed products for the Winter Olympics.
In Car No. 5, all kinds of Winter Olympic badges, toys and other licensed products are filled with the tabletop.
One of them, "Holding the Future·Beijing Winter Olympics Broken Banknote Curling Ornaments" attracted the attention of many people.
According to the staff of Beijing Railway Service, the production of this product also embodies the concept of environmental protection.
"It is made of non-qualified scraps produced in the production process of RMB as the main material. It contains about 880 broken banknotes with a denomination of one hundred yuan. The concept of environmental protection." (End)
