The 2022 Berlin International Trade Fair for Transport Technology (Inno Trans 2022) is taking place again with a grand opening.With the theme of "Intelligent Travel to the Future"CRRC showcases a number of well-known products sharing the "Green and Intelligent" integrated solutions with the world CRRC Times Electric also displays its technical intelligence at InnoTrans 2022.
Integrated whole life-cycle intelligent solutions for rail transit
With integration, synergy and digital empowerment, CRRC Times Electric creates integrated intelligent solutions for the whole life cycle of urban rail transit, promoting the safe, efficient, green and intelligent development of urban rail transit. In the construction stage, we develop intelligent products that are multi-disciplinary, integrated and synergistic to create a "Vehicle-ground Integration" electromechanical system; in the operation and maintenance stage, we utilize digital empowerment to operate and maintain business and build a multi-disciplinary intelligent operation and maintenance platform. The solution has been successfully applied to Wuxi S1 line, which is expected to improve the overall operations and maintenance efficiency by 20% and save energy by 20%. The company plans to apply for intelligent urban rail transit demonstration project, which will be subsequently applied in Qingdao, Changchun, Chongqing and other cities.

Intelligent driving system for heavy-duty trains .
The intelligent driving system for heavy-duty trains integrates advanced technologies including intelligent perception, intelligent dispatching and expert diagnosis, which realizes intelligent control of heavy-duty trains with 10,000 tons from automatic wake-up, automatic preparation, running between stations to automatic warehouse entering and dormancy. The world-leading technology provides an efficient and green intelligent system solution for heavy-duty freight. This system has been successfully applied to Baotou-Shenmu Railway of CHN ENERGY, China Railway Xi'an Group and China Railway Taiyuan Group, etc. Since it was put into service in 2019, it has covered 9 models and 7 railway companies, with a total safe running distance of over 1.3 million kilometers, which has improved operational efficiency and reduced energy consumption for customers.
Key features of the product:
Highly intelligent, the automation function covers locomotive depot operation, inter-section operation and station operation, with the automatic train control rate exceeding 98%, which greatly reduces the labor intensity of the crew.
Safe and reliable, core hardware platform security level reaches SIL4, with dual-system hot standby redundancy technology applicable.
Energy conservation and environment protection, energy saved by 3% -5%
Smooth operation, longitudinal impact force reduced by 5%-10%.
