Adaptive Moving Platform Door System for All Types of Trains

The safety protection of railway platforms in China is facing the problem of difficult matching between platform doors and train doors under the condition of colocation and co-platform operation of different types of trains. With the rapid advancement of the "four network integration", the development trend of cross-line and network operation of trains will inevitably exacerbate the complexity and severity of this problem. This paper proposes a design scheme for a self-adaptive movable platform door system for all types of trains. By setting a full-length track at the edge of the platform and staggering the movable platform doors, it achieves precise alignment between platform doors and train doors. Finally, the prototype development, functional verification and optimization are completed in a laboratory environment, indicating that it can meet the practical needs of railway platform safety protection in China and adapt to industry development trends.
