China's first smart digital subway train VELLINK unveiled: can achieve active optimization of operations, intelligent development of driving strategy我国首列具身智能数字地铁列车 VELLINK 亮相：可实现主动优化运营、智能制定行车策略

IT House news on October 12th, according to CRRC Changchun Railway Bus Co., Ltd., led by the company, jointly developed by Chengdu Rail Transit Group Co., Ltd. and other units, the green smart fusion digital subway train VELLINK was officially unveiled recently, which is "China's first intelligent digital subway train". IT House learned that the car is equipped with body intelligence technology for the first time in the world. Relying on global sensing networks, self-developed artificial intelligence algorithms and high-speed communication technology, it has intelligent perception, intelligent decision-making and intelligent interaction capabilities, and can shift from passive execution of instructions to active optimization of operations. In view of the problems of redundant equipment, complex electrical layout and high energy consumption of traditional subway trains, VELLINK has optimized the system architecture, power supply link and load-bearing structure. For the first time, the train uses the concept of function domain, integrating the three major systems of intelligent operation, passenger service and real-time monitoring to streamline the control host by 50% and optimize the wiring of the entire train by 30%. By reconstructing the voltage conversion link of the air conditioning and auxiliary power supply system, its power efficiency is improved by about 9%; the roof, air duct and sound insulation materials of the car body are integrated and integrated design, and at the same time bear the load, air supply and heat insulation functions. In terms of green and low-carbon, the train uses lightweight materials such as carbon fiber, magnesium aluminum alloy, and polycarbonate on a large scale, and adopts a structure such as a bogie built into the axle box, electromechanical braking, and an integrated roof, which reduces the weight of the whole vehicle by about 18%. The application of energy-saving equipment such as permanent magnet traction systems and high-efficiency silicon carbide converters has resulted in a comprehensive energy-saving rate of more than 10% for the entire vehicle and a reduction of carbon emissions by about 15% throughout its life cycle. Environmentally friendly materials such as biodegradable floor cloth, paint-free wall panels, and water-based paint are used in the car, and are equipped with oil-free air compressors, air purification devices, and elastic wheels. In addition, the train is equipped with equipment such as radar, high-definition cameras and sensors to sense the line environment and operating status in real time through multi-modal perception of large models, and to determine road conditions and equipment status in advance. Relying on the train communication, the vehicle-mounted edge computing power platform and the large model of "Zhuo Wheel" independently developed by CRRC, the train can intelligently formulate the driving strategy.
