Yesterday morning, the "Puzhen made" Nanjing Line 9 subway train was unveiled to the public for the first time, and the train has the characteristics of safety and reliability, intelligence and efficiency, environmental protection and comfort, economy and applicability, energy saving and consumption reduction.

The orange-red appearance of the Metro Line 9 train is full of vitality, and the front of the train continues the "smiley" family elements of Nanjing Metro, and boldly innovates on this basis, and the overall style is simple and clear, friendly and comfortable.

This train is also quite high-tech. According to reports, video analysis technology is used on the train, and during peak periods, passengers can check the congestion in the carriage in the station and flexibly choose to take the carriage. If a passenger arrives at the terminal and accidentally leaves behind their belongings, video analytics can also quickly identify and warn them. In addition, the video analysis technology can also monitor the driver's driving situation, if the driver is fatigued driving, eye deviation, off-duty monitoring, etc., this intelligent assistant will carry out a "friendly reminder". In addition, cutting-edge technologies such as Ethernet vehicle control, intelligent O&M, and 5G/Wi-Fi6 vehicle-to-ground transmission systems can enable the full vehicle data to be transmitted to the ground vehicle intelligent O&M server quickly, timely, and with high quality, so as to achieve real-time monitoring and O&M decision-making.

"This is Nanjing's first Chinese standard subway 80B train, and the key components on the vehicle are all independent products, with a vehicle autonomy rate of 98.36%." Zong Qingze, the overall designer of the technology center of CRRC Puzhen Company, told reporters that the train is a B-type car with a speed of 80km/h, using a four-moving, two-towing and six-car marshalling type. This means that most of the technical parameters, installation interfaces, system equipment, etc., of the vehicle are consistent with other standard metro platform projects. When maintenance is required, it can be quickly replaced or directly replaced through simple adjustments, which greatly improves the efficiency of vehicle operation and maintenance and prolongs the service life of the train.

The relevant person in charge of Puzhen Company said that the debut of the train is a demonstration of the achievements of Puzhen Company to break through key core technologies and build technologically advanced standardized subway trains in China. In the process of promoting the independence and technological upgrading of core technologies and key components, through the localization of key technologies, energy saving and greening, and intelligent operation and maintenance, a series of Chinese standard subway train development platforms and technical standard systems have been established, which has enhanced the product quality, innovation ability and comprehensive competitiveness of the rail transit equipment manufacturing industry.
