PARTNER – Beijing Zongheng Electro-Mechanical Technology Co., Ltd. (abbreviated as ZEMT) is a wholly-owned subsidiary of China Academy of Railway Sciences. ZEMT is a China leading technology company supplying advanced mobility products and systems for rail vehicles, including high-speed railway and urban transit, and providing comprehensive solutions for customers.

Building on its robust technical foundation, accumulated over the years through its mature and advanced traction, braking, and TCMS product platforms, ZEMT boasts significant advantages. To meet the growing demands of operators and to align with the evolving trends in train development, ZEMT has announced the future rail vehicle system architecture, known as the Fully Electric Drive Integrated System (FEDIS). This superior, more advanced, and intelligent integration platform leads to the innovative development of future rail vehicle technology.

The FEDIS exploits fully electric drive technology to deliver traction and braking capabilities, replacing traditional air brakes with advanced EMB systems. By transitioning from a subsystem-oriented design, this innovative platform establishes a fully electric drive-integrated architecture, which is defined by “centralized train management, decentralized execution control, and integrated drive systems”, ensuring unparalleled efficiency and performance for future rail vehicles.

The Fully Electric Drive Integrated System is divided into the ‘Control Integration Layer’,’Power Integration Layer’ and ‘Information Integration Layer’. The Control Integration Layer adopts highly safe, reliable, and high-performance integrated control units, providing a more powerful brain for train control. It achieves the integration of comprehensive vehicle control functions and coordinated management, reducing interaction delays between critical systems to optimize system performance.

The Power Integration Layer subverts the traditional architectures, it employs new-generation electro-mechanical braking technology to completely eliminate air brake systems, unifying traction and braking functions using fully electric drive device.

The Information Integration Layer, utilizing time-sensitive networking technology, integrates all data to enable capabilities in intelligent perception, intelligent decision-making, and intelligent maintenance.
The Fully Electric Drive Integrated System (FEDIS) solution offers enhanced flexibility and efficiency to meet operator requirements. Additionally, car builders can achieve comprehensive train management and control through the FEDIS platform. The inception and announcement of FEDIS represent the culmination of train electrification and signify the advent of the intelligent era in rail transit, guiding the way for a more expansive future as a pioneer.
