On December 22, the new Lanzhou to Zhangye 34 line railway (Zhongwu section) project came with good news, Tianzhu West Station signal building communication system and signal system equipment installation, equipment commissioning, equipment test has been completed, the rest of the station signal building has entered the equipment commissioning stage, for the completion of the overall goal of the project to open to traffic has laid a solid foundation.
Tianzhu West Signal Building includes communication lines, transmission and access systems, data communication networks, wired dispatching communications, mobile communications, integrated monitoring, emergency communications, integrated wiring, etc. Shen Zhi, chief engineer of the "four electric" project department after the new Lanzhang third and fourth line railway (Zhongwu section) station, introduced that the railway signaling system is like a human brain, shouldering the functions of unified dispatching and directing train operation, ensuring train safety and improving train operation efficiencyThe railway communication system is like a human neural network, which transmits and processes various information through various communication methods, and builds a bridge for the connection of other systems.
It is reported that China Railway Electrification Bureau Group is responsible for the construction of the new Lanzhang 34-line railway (Zhongwu section) communication, signal, power and electrification "four electrics" system, of which the weak current project includes signal system and communication system. In the construction process, the "digital first" model was proposed for the first time, using BIM technology to build a digital virtual model for the communication and signal room of Tianzhu West Station, and after the evaluation and acceptance of the digital model by all parties, the three-dimensional visualization BIM technology was made to guide the on-site construction, so that it could be more intuitive and standardized, and the digital and physical engineering evaluation of the first project of the "four electrics" was realized.
The new Lanzhou to Zhangye three or four lines of railway connect the provincial capital Lanzhou and Lanzhou New Area and Wuwei City, and the current construction of the new line from Zhongchuan Airport to Wuwei is 194269 kilometers, with a total operating length of 25456 km. The project is an important high-speed railway regional connection line in China's medium and long-term railway network planning, and after completion, it will help strengthen the connection between the land bridge passage and the Jinglan corridor, improve the layout of the high-speed railway network in the western region of Gansu Province, and promote the formation of the fast passenger transport channel of the Hexi Corridor in Gansu Province.
