A world first! Airport MRT straddle monorail vehicle Chongqing off the assembly line!

Rail Transit Exhibition News On November 28, the monorail rapid transit system of Chongqing Jiangbei International Airport, independently developed by CRRC Changqing Co., Ltd., rolled off the assembly line in Chongqing. This vehicle project is the world's first straddle monorail system solution tailored for the airport rapid transit system, opening up a new model of airport rapid transit and highlighting various highlights in terms of smart operation, customized smart services and green transportation.

Smart operations

The monorail rapid transit system of Chongqing Jiangbei International Airport adopts GOA4 level automatic driving system, independent power unit, automatic coupler and Ethernet control, which can realize the tripartite linkage of flight, station and vehicle, and can be automatically assigned and flexibly grouped according to the changes in flight passenger flow, and the operation is intelligent and efficient.

Customized smart services

In view of the personalized needs of passengers at the airport, such as a large amount of luggage and a short interval between getting on and off the bus, 9 fixed seats and 2 folding seats are set at the end of the passenger room, and 3 doors with an effective opening of 1.4 meters are set on both sides. In addition, the vehicle integrates smart windows, intelligent passenger counting, intelligent air conditioning, intelligent evacuation and other systems to create an intimate and meticulous travel experience for passengers in an all-round and in-depth manner.

Green transportation

The vehicle is equipped with supercapacitors, which replace the traditional catenary power supply through on-board energy storage, cancel the contact rail and return rail on the whole line, reduce the line loss, and use the supercapacitor to absorb braking regeneration energy, effectively improving the energy recovery rate. The vehicle adopts a permanent magnet synchronous motor, and the motor rotor is upgraded to a permanent magnet, which increases the energy conversion efficiency by 5%, reduces the weight by 30%, and increases the energy-saving efficiency by 10%. The vehicle is equipped with a high-frequency auxiliary inverter, and the volume and weight of the equipment are reduced to about 10% of the power frequency design, making the vehicle more energy-efficient. At the same time, through the application of lightweight materials for vehicles, the operating energy consumption is reduced.
