北京冬奥会高科技特色主要体现在哪些方面,请问北京冬奥会高科技有哪些?
据和记百科网站「薄荷べ浅浅绿」消息,近日,北京冬奥会高科技特色主要体现在哪些方面,请问北京冬奥会高科技有哪些?引发热议,北京冬奥会高科技特色主要体现在哪些方面同样引起许多争议,对此众网友各抒己见。但到底是怎么回事呢?和记百科为您解答。
1、采用直冷制冰技术和储雪技术:首都体育馆引入直冷制冰技术、改变冰场构造等方式,实现快速升降温,2小时内即可完成冰面转换。同时可以打造最快的冰,采用这项技术,可将冰面温差控制在0.5℃内,碳排放接近于零。同时利用冷热联供一体化设计,对制冷余热进行回收利用,能效提升30%-40%。这项技术被大规模应用于冬奥会是奥运会首次。
2、大竖屏:开幕式现场,鸟巢中心最为显眼的就是那块大竖屏,它是一块近60米高、20米宽的LED屏,名为冰瀑。为了保证其在秋冬季节风速过大时,不被风吹碎,技术团队克服了重重困难,记录了100-200多种风况来攻克这一技术难题。
3、地幕:开幕式出现在地面上的那块显示屏,是由8K超高清地面显示系统构成,面积为10393㎡,包含超过4万块LED模块。为了保证在如此大的画面上达到完美融合并产生绚烂的色彩和画面,采用了多个8K+级分辨率的画面融合技术。
4、冰立方:开幕式上的最大亮点,无疑是那个破冰而出的冰立方了,它的总重量约400吨,升降重量达180吨,放在一个84m×42m×10m的坑内,升降载荷超过了一般大剧场大型升降台的8倍。
5、防疫神器体温贴:外表很像创可贴,其实是内置芯片的袖珍无线电子测温计,检测体温误差0.1-0.2℃。通过手机APP绑定,它将涉奥人员实时体温远程上报给数据后台。系统每3秒采集一次体温数据,一旦超过37.3℃,就会自动向防疫人员报警。
【英文介绍/For English】:
1. Adopt direct-cooling ice-making technology and snow storage technology: Capital Gymnasium introduces direct-cooling ice-making technology and changes the structure of the ice rink to achieve rapid temperature rise and fall, and the ice surface conversion can be completed within 2 hours. At the same time, the "fastest ice" can be created. Using this technology, the temperature difference between the ice surface can be controlled within 0.5 ℃, and the carbon emission is close to zero. At the same time, the integrated design of combined cooling and heating is used to recycle the waste heat from cooling, and the energy efficiency is increased by 30%-40%. It is the first time that this technology has been applied to the Winter Olympics on a large scale.
2. Large vertical screen: At the opening ceremony, the most conspicuous part of the Birds Nest Center is the large vertical screen, which is an LED screen nearly 60 meters high and 20 meters wide, called "Ice Waterfall". In order to ensure that it will not be "blown" by the wind when the wind speed is too high in autumn and winter, the technical team has overcome many difficulties and recorded more than 100-200 kinds of wind conditions to overcome this technical problem.
3. Ground screen: The display screen that appeared on the ground at the opening ceremony is composed of an 8K ultra-high-definition ground display system with an area of 10,393 square meters and contains more than 40,000 LED modules. In order to ensure perfect fusion on such a large screen and produce brilliant colors and pictures, multiple 8K+ resolution picture fusion technologies are used.
4. Ice Cube: The biggest highlight of the opening ceremony is undoubtedly the Ice Cube that broke the ice. Its total weight is about 400 tons, and its lifting weight is 180 tons. It exceeds 8 times that of the large lifting platform of the general theater.
5. Anti-epidemic artifact body temperature sticker: It looks like a Band-Aid, but it is actually a pocket wireless electronic thermometer with a built-in chip. The temperature error is 0.1-0.2℃. Through the binding of the mobile APP, it will remotely report the real-time body temperature of the Olympic personnel to the data background. The system collects body temperature data every 3 seconds, and once it exceeds 37.3°C, it will automatically alert the epidemic prevention personnel.
