Fully automated Hangzhou Metro train functions

The automation covers the complete operational cycle. This includes wake-up and sleep, self-diagnosis, depot entry and exit, mainline operation, station stopping and door operation, and train washing.

Also, the onboard intelligent systems include active and passive obstacle detection. They also include safety monitoring for the running gear. Critical circuits and key subsystems use redundant design in an effort to enhance operational safety.

The train is also equipped with self-healing capabilities. These include automatic subsystem reset and remote control, ensuring high availability under abnormal conditions.

Traction, energy saving and passenger systems

The train uses a permanent magnet traction system. It aims to deliver overall energy savings of more than 20%. In addition, its air-conditioning system combines antibacterial and antiviral purification with intelligent airflow distribution technology.

To further reduce vibration and noise, the vehicle also uses high-seal electric plug doors, sound-insulating pads, and high-performance sound insulation materials.
