Features

  • icon12.svg
    SIL2 Safety Certification
    • The system adopts redundancy design and has SIL2 safety certification.

  • icon13.svg
    High Stopping Accuracy
    • The system can accurately stop on the platform with stopping deviation less than 50cm on the 350km/h high-speed railway line.

  • icon14.svg
    ATO Self-learning Technology
    • The system adopts online self-learning technology to realize more accurate train control, so as to eliminate the influence of train control caused by line changes and vehicle performance differences, and enhance the robustness and stability of ATO controller.

    Energy Saving
    • While meeting the operation target, the system optimizes the dwell time and trip time of trains at various stations and block sections, so as to achieve the macro-level energy efficiency. It also saves energy for each single train through the automatic control algorithm of train speed when the traction voltage collection is added as the basis for calculating the target speed.
