PowerChina participated in the construction of the world's first intelligent high-speed railway

Beijing and Zhangjiakou inherit for a hundred years and gather Chinese wisdom. On December 30, 2019, the newly built Beijing Zhangjiakou high-speed railway participated by PowerChina was officially put into operation, opening a new era of intelligent high-speed railway in the world.

from "Beijing Zhangjiakou Railway" to "Beijing Zhangjiakou high speed railway", one Beijing Zhangjiakou Railway and two Beijing Zhangjiakou railways have the same starting point and end point, but they have witnessed the humiliation and glory of China in the past hundred years. In 1909, the Beijing Zhangjiakou Railway designed and built by Zhan Tianyou was the first trunk railway designed and built by the Chinese themselves, breaking the foreign powers' assertion that China could not build its own railway. 110 years later, the Beijing Zhangjiakou high-speed railway has been completed and opened to traffic, refreshing the world's new understanding of high-speed railway and setting a new benchmark in the world's high-speed railway field. As the first intelligent high-speed railway in the world, the Beijing Zhangjiakou high-speed railway "Fuxing" intelligent upgraded train adopts Beidou satellite navigation system independently developed by China. It is the first time in the world to realize automatic driving at a speed of 350 kilometers per hour. It has the functions of automatic departure of stations, automatic operation of sections, accurate automatic benchmarking of stations, automatic door opening protection, etc.; in addition, in service Beijing Zhangjiakou high-speed railway is also more convenient and comfortable, with one pass, face brushing, intelligent navigation in the station And a series of technologies to bring better travel for passengers. After the opening of the

high-speed railway, the fastest time to take the high-speed railway from Beijing to Zhangjiakou will be shortened to within one hour, and it will be connected with the two high-speed railway lines of Huzhang and Dazhang, which is of great significance for promoting the coordinated development of Beijing, Tianjin and Hebei and connecting the western region. It will also play an important role in the 2022 Winter Olympic Games.

in addition to the intelligent operation, Beijing Zhangjiakou high speed railway will also run through the intelligent construction throughout the whole railway construction. The eighth bid section of Beijing Zhangjiakou high speed railway constructed by China Power Construction and hydropower seventh bureau is located in Zhangjiakou City, with a total length of 33.38km, including 11 subgrade sections, 12 bridges and 2 tunnels, of which caomaoshan tunnel and Zhangjiakou South super large bridge are the control and key and difficult projects of the bid section. During the construction, in strict accordance with the requirements of "excellent project, intelligent Jingzhang", the application of modern technologies such as cloud computing, Internet of things, big data, mobile Internet, etc. will be integrated into the project construction, and the informatization and intelligent construction of the project will be vigorously promoted. The project leader of Sinohydro Bureau 7 introduced that in the production management system, the visual management of on-site operation can be achieved through remote monitoring. The construction process "QR code", project quality traceable "QR code" and main control project standard "QR code" can be set on site. The combination of QR code and smart phone can be fully used to realize cross platform "super media" construction The application of technology enables the technical and construction personnel to scan, understand, master and apply relevant technologies through mobile terminal app conveniently and quickly at any time and anywhere, so as to realize the modernization and intelligence of on-site construction technology management application; at the same time, the mode of "Bim and Internet +" is adopted to apply the construction management platform of railway project to real-time control the construction progress and plan implementation, and simulate the progress of the project The existing construction plan and construction team shall be dynamically adjusted to meet the construction requirements. In addition, the project department also actively explored a new way of "tooling" to protect "technology" in combination with the characteristics of the bid section. The degree of construction mechanization has reached more than 90%. A series of "black technologies" have been introduced, such as face recognition system, video monitoring system of bridge erecting machine, automatic spray system of slope greening, hydraulic automatic walking inverted arch trestle, etc. Both the flexible use of information technology and the use of tooling and equipment epitomize the rapid development of Beijing Zhangjiakou high speed railway and even China's high speed railway towards intelligence.

one hundred years ago, the old Jingzhang told the world with facts that China could do it; a hundred years later, the new Jingzhang demonstrated its strength to the world, and China is doing better, from self-reliance to prosperity and prosperity, from lagging behind people to leading the world. Today's China, just like Jingzhang, which has spanned a hundred years, strides forward in a stronger and better direction.
