"Beijing Zhangjiakou Railway open to traffic" reflects the achievements of China's scientific and Technological Development
. On December 30, 2019, the intelligent Beijing Zhangjiakou high speed railway with a speed of 350 kilometers per hour designed and built by the Chinese people opened to traffic. (according to the people's railway on January 2, 2020) the mention of the Beijing Zhangjiakou Railway in
reminds people of the fact that the first railway designed and constructed by Chinese people in 1909, though only 35 kilometers per hour, is still the glory and pride of Chinese people and Chinese railway engineering technology, and the wisdom and strength of Chinese people under the humiliating history. 110 years later, China has entered a new era of independence and prosperity. On this line, the Chinese have built the world's most intelligent railway line. The difficulties faced by the construction of the Beijing Zhangjiakou high speed railway are rare in the history of the same kind of construction in the world. The Badaling tunnel with a total length of 12.01 kilometers is the longest and most difficult section of the whole Beijing Zhangjiakou high speed railway. Not only is the geological environment complex, there are high risks such as water gushing and mud bursting, but also it has to pass through the core area of the Badaling Great Wall and Qinglongqiao station for a hundred years. In order to do a good job in the world cultural heritage The protection of Badaling Great Wall requires that the ground surface must not settle at all during the whole construction process. Under such difficulties, the railway people used precise micro damage control blasting technology, and pioneered the use of BIM Technology, human vehicle positioning system, intelligent traffic command system and other world advanced information technology to successfully achieve tunnel through. As the first intelligent high-speed railway in the world,
uses Beidou satellite navigation system and GIS technology independently developed by China to "locate" the Beijing Zhangjiakou Railway into a large network, providing intelligent services for operation, dispatching, maintenance and emergency response; every rail and parts in the whole line are diagnosed by "self experience" system, all of which are connected to the computer terminal through sensors End. E-ticket allows passengers to experience the convenience brought by mobile ticket purchase. After ticket purchase, the mobile phone will give a ride reminder and choose the best way to get to the railway station to give an optimized reminder. After arriving at the railway station, you only need to pause for one second to "brush your face" to get in and out of the station without barrier. When entering the station, the intelligent interactive tool enables human natural language and advanced machine intelligence For interactive service experience, the intelligent robot can closely navigate and carry luggage for the passengers; the spacious and fashionable carriage design on the train, WiFi without gap coverage, wireless charging and intelligent adjustment of light intensity and color, and the stepless color changing window can define the color at will, and cooperate with various fields and landscapes, a romantic and warm journey will start, so that the passengers can experience the super value experience. The whole EMU painted with the theme of 2022 Winter Olympic Games is also equipped with a media carriage specially designed for the Winter Olympic Games. Each seat has a power plug and a workbench as well as a space for placing interview equipment, and a place specially designed for skiers to place skiing equipment, which will better serve special groups. The
Beijing Zhangjiakou Railway Intelligent EMU is the first time in the world to realize the 350 km / h automatic driverless train. The whole vehicle is resistant to the cold and the interior materials are recycled in a green way. All of these represent the development strength of China's science and technology, the strongest technology of the world's Railway Science and technology, and it will represent the direction of China's railway development and lead the trend of the world's railway development 。 (Zhang Jun)
