China's First Embodied Intelligent Digital Metro Train VELLINK Unveiled
China's first embodied intelligent digital metro train, VELLINK, has been unveiled. Developed by CRRC Changchun Railway Vehicles and partners, the train can actively optimize operations and intelligently formulate driving strategies.
CRRC Changchun Railway Vehicles has unveiled VELLINK, China's first embodied intelligent digital metro train. This train, led by CRRC Changchun in collaboration with Chengdu Rail Transit Group and other entities, marks a significant advancement in metro technology by integrating "embodied intelligence."
The VELLINK train globally debuts embodied intelligence technology, leveraging a comprehensive sensing network, self-developed AI algorithms, and high-speed communication. This enables intelligent perception, decision-making, and interaction, allowing the train to shift from passively executing commands to actively optimizing its operations.
Addressing issues like equipment redundancy, complex electrical layouts, and high energy consumption in traditional metro trains, VELLINK features optimizations in system architecture, power supply, and structural design. The integration of intelligent operation, passenger service, and real-time monitoring systems has reduced control hosts by 50% and wiring by 30%. Power efficiency is improved by approximately 9% through redesigned air conditioning and auxiliary power systems.
The train emphasizes green and low-carbon principles, utilizing lightweight materials like carbon fiber and magnesium-aluminum alloys, resulting in an 18% weight reduction. Energy-saving components, including permanent magnet traction systems and silicon carbide converters, enhance overall energy efficiency by over 10% and reduce lifecycle carbon emissions by approximately 15%. Eco-friendly interior materials are also incorporated.
