On the white snow, a seemingly ordinary red car card is like a transformer, rapidly extending a space of nearly 100 square meters. There are not only a wax bench and snowboard storage cabinet, but also an area for athletes to warm up and rest, just like a mobile snow logistics base. This is the largest snow wax car with single-layer compartment area in the world. It is also the first snow wax car independently developed by China and with complete independent intellectual property rights.
Waxing snowboards is a very important service technology in skiing. The waxed snowboard is like a "car with a light steering wheel", which can not only help athletes save energy, but also be easier to control. In large-scale international competitions, many ice and snow powers will provide their own players with special waxing cars. Previously, China has been a blank in the field of snow wax vehicles.
In only 11 months, the first domestic snow wax vehicle integrating a new generation of information technology independently developed by Shandong Province officially went offline in September 2021. At present, it has successfully completed the guarantee task of three stops of the International Snow Federation cross-country skiing FIS points series. Now, the snow wax car has arrived in Beijing to make final preparations for the national cross-country skiing team's impact on the Winter Olympics.
in only 11 months, winter sports equipment achieved zero breakthrough
During skiing, the snowboard rubs with the snow surface to generate heat, and the melted snow forms a layer of water film, which will damage the snowboard and reduce the sliding speed. In the fierce race such as skiing, a 0.01 second gap may miss the medal. Therefore, professionals are required to wax the snowboard according to the temperature, humidity and snow field conditions.
Previously, Chinese athletes did not have their own snow wax cars and could only operate in the open air or rent simple flat houses. "In the past, when we played abroad, we usually set up a stall like a barbecue in the open space next to the stadium to wax; in the venues with better conditions, we used containers as temporary waxing rooms." Wang Yan, deputy leader of the national cross-country skiing training team, said.
In order to fill the gap in China's snow wax vehicle equipment and improve the service guarantee level of the national team for the 2022 Beijing Winter Olympics, the State Administration of sports entrusted Shandong to carry out the development of snow wax vehicles in November 2020. Shandong Province has established a snow wax vehicle joint research headquarters with two vice governors as the general command, which has gathered more than 10 units and more than 1000 technical forces, including Shandong Provincial Department of industry and information technology, Shandong Provincial Bureau of sports, Shandong Provincial Department of science and technology, Sinotruk Jinan Truck Co.Ltd(000951) , Shandong Industrial design and Research Institute, Taishan sports industry group, Haier and Hisense.
"China's most dazzling first snow wax car represents the highest level of manufacturing in Shandong!" At the press conference held by the Information Office of Shandong Provincial People's Government on December 10, 2021, Ling Wen, vice governor of Shandong Province, said emotionally when introducing the snow wax car made in Shandong. Just like the big words "China national team" printed on the snow wax carriage, this car is of great significance and represents a new breakthrough in China's winter sports equipment.
"When we first heard about this task, we didn\'t even know what the snow wax car was, let alone manufacturing." Recalling the research and development process of the first domestic snow wax vehicle, Guan Xiaoyan, Secretary General of the snow wax vehicle joint research project headquarters of the Beijing Winter Olympic Games and director of the light industry and Textile Industry Department of Shandong Provincial Department of industry and information technology, expressed a lot of emotion in an interview with the reporter of China electronics daily.
Without the guidance of technical experts, drawing query and real vehicle reference, the design work is like a difficult puzzle; It is a great challenge for the R & D team to complete the leap from scratch and from existence to excellence in 11 months.
"It was the first time that we explored the construction of snow wax vehicles, such as toilets, shower rooms and lifting platforms. At the beginning of the design, these functions were not available. After repeated communication and demonstration by the project team personnel, these functions were fully equipped one by one. In the stage of scheme demonstration and technical demonstration, the project team personnel repeatedly discussed and improved, and they could only sleep two hours a day when they were most nervous." Liu Xiping, deputy director of special vehicle design department of Sinotruk Jinan Truck Co.Ltd(000951) group application engineering development center, told reporters, "In the whole process, it took more than 4 months to review the scheme and repeatedly demonstrate and adjust the technical design. 79 patents were sorted out in the whole project development process. Sinotruk Jinan Truck Co.Ltd(000951) the design data of the snow wax car saved by the group on the computer amounted to hundreds of G. only the wax beating table in the snow wax car was revised six times, and more than 600 design drawings of the snow wax car tractor were drawn."
The headquarters took the units involved in R & D to study and investigate everywhere, held many consultations with the waxers of the national team, and gradually established the understanding of snow wax vehicles, so as to have the prototype of Chinese snow wax vehicles. It took only 11 months from design, R & D to manufacturing. On September 26, 2021, China snow wax car was officially delivered offline.
\u3000\u3000 "When the whole vehicle is deployed, it is about 20 meters long and about 8 meters wide. The effective use area is 92.5 square meters. In these areas, we have designed waxer work area, athlete warm-up area, lounge and storage area, including functional areas of toilet and shower, as well as electric lifting platform for disabled athletes, which is the largest single-layer deployment area in the world The most fully integrated snow wax car! " Guan Xiaoyan is like a family treasure.
three highlights reflect the new achievements of "China's Intelligent Manufacturing"
The Winter Olympic snow wax car independently developed by China is a "big guy" weighing more than 50 tons. It looks "ordinary" on the outside, but there is " Shanghai Dzh Limited(601519) " in it.
"Big" is the first impression of looking at the snow wax car from a distance. As soon as you walk into the door, you will find that it is not only big, but also has a large internal space. In the process of snow wax vehicle, the car body is 35 square meters, but in the working state, the car body is fully expanded, with an area of 92.5 square meters. It is the largest snow wax car in the world.
Snow wax car is not only the working room of waxers, but also the preparation room and leisure room for athletes' pre competition warm-up, snowboard storage, rest and entertainment. The compartment space is divided into seven functional areas: outdoor warm-up area, snowboard waxing area, snowboard storage area, temporary work rest area, oxygen enriched rest and entertainment area, snow wax storage area and sanitary shower room. The car is equipped with VR entertainment, biochemical toilet, smart home, training equipment, audio and other equipment to provide a comfortable and convenient environment for athletes and waxers, It is the most fully functional snow wax car known at present.
Snow wax car is not so much a car as a new intelligent space tailored based on low-temperature environment and integrating a new generation of information technology, which is also the core intention of "intelligent manufacturing".
A 32 inch electronic screen standing next to the waxing platform is the "wisdom center" of the whole snow wax car. The electronic screen integrates two functions of monitoring and control to monitor air quality parameters, temperature, humidity, water heater, etc., which not only enables all functions of the car body to realize one key switch, such as on-board photovoltaic, on-board air conditioning, etc., but also guides the waxer to match the snowboard with the most scientific wax type and grinding method.
Compared with the foreign upper exhaust scheme, the lower exhaust system of this snow wax vehicle in China optimizes the structure of the fan and shortens the air duct distance, which can make it have stronger suction and higher exhaust efficiency, and quickly absorb the harmful substances produced in the waxing process. The relevant person in charge of helcaos told China Electronics News that in order to solve the problems of low temperature and hot start in the vehicle and narrow installation environment, Haier commercial air conditioner has newly applied for 6 invention patents, including solving the control and detection of machine low-temperature heating start, electric heating start, new fan with internal circulation function Low temperature heating start of air conditioner, control method to prevent low pressure fault, etc; Based on the customized design module of CAOS cosmoplat industrial Internet platform, it provides a one-stop safe and reliable healthy air solution for snow wax vehicles.
"All sports equipment on the snow wax car has been improved intelligently according to the characteristics of winter sports and the needs of athletes." Gao Aidong, general manager of the new business department of Taishan sports industry group, told China electronic news that through the allocation of intelligent sports equipment, an integrated, intelligent and full scene model of athletes\' own epidemic prevention safety, physical condition analysis, warm-up, training and recovery will be created. In addition, Taishan sports is also equipped with AI intelligent physique detection integrated machine for snow wax vehicles. Based on computer vision recognition technology, it can provide athletes around the world with accurate physique detection data.
The "display scheme" in the snow wax car can not be underestimated. According to Hisense Visual Technology Co.Ltd(600060) , the environment of ice and snow competition in the Winter Olympic Games puts forward high requirements for display equipment, which needs to achieve excellent image quality effects in minus 30 ℃, outdoor high brightness and wind and snow. In order to ensure the operation reliability in low-temperature environment, Hisense Visual Technology Co.Ltd(600060) specially selected low-temperature resistant glass panel and low-temperature materials for u7g-pro, and conducted sufficient laboratory low-temperature tests to ensure excellent display effect at minus 30 ℃.
In fact, this car is not only "intelligent", but also practices the concept of "Green Olympics". It is understood that the snow wax vehicle adopts hydrogen fuel power tractor and is equipped with China's most powerful hydrogen fuel cell, with zero emission and zero pollution; Another hybrid tractor used under some conditions adopts the internationally leading 50% thermal efficiency engine, which can reduce fuel consumption by 15% under the same working conditions and achieve energy conservation and emission reduction.
the snow wax car follows wherever the national team goes
To ensure the training competition of the national team, it is destined to travel long distances through mountains and rivers. Not long ago, at the FIS cross-country skiing points series of the International Snow Federation, China's first snow wax car independently developed welcomed a full house of applause when it appeared for the first time.
"Our own snow wax car is really good!" This is the heartfelt sigh of the athletes of the national cross-country ski team after boarding the Chinese snow wax car. Terje, the waxer of the cross-country ski national team, praised the light tracing system of the waxing platform: "this is really very useful. Compared with the waxing environment that can only be observed with ambient light in the past, the adjustable light source can facilitate the waxer to observe the ski from different angles and avoid subtle waxing defects, which will affect the performance of the ski."
During the guarantee period of Xinjiang hot spring station, the wind and snow were extremely fierce in the wilderness of the northwest border of the motherland. The snowboarder wore wax in the snowboard, but there was no sign of wax in the snowboard.
Since the first domestic snow wax car was delivered, it has traveled more than 10000 kilometers with the national team to Xinjiang, Hebei, Shanghai, Beijing and other places. In the guarantee process of the three races of Xinjiang hot spring station, Hebei Chongli station and Shanghai Yangpu station, it has withstood the tests of long-distance driving, plateau climate, ice and snow low temperature, strong wind and bad weather. The snow wax truck provides power and heating 24 hours a day, and 6 waxing equipment provide high-quality equipment foundation for waxers.
It is understood that this snow wax car has applied for 79 patents, including 22 invention patents. It is not only a key equipment to support and protect the skiing training and competition of the national team of the Beijing Winter Olympic Games, but also will serve the national team for a long time.
Recently, the snow wax car has arrived in Beijing to make the final preparations for the national cross-country skiing team's impact on the Winter Olympics. In 25 days, this snow wax car will witness the historical moment of Olympic athletes' brave achievements with the world.
