Such safety issues have also occurred on existing lines.

[0003] After searching, Chinese patent publication No. CN115959175A discloses a method and device for detecting obstacles in the gap between train doors and platform doors. Specifically, when a train in FAM mode is detected to arrive at the station and the platform door is detected to change from an open state to a closed state, a start detection instruction is sent to the gap detection system, instructing it to send the gap detection result to the train control system, and continuously receiving the gap detection result fed back by the gap detection system. Within a preset time after sending the start detection instruction, a no obstacle alarm message is continuously sent to the train control system; after the preset time and before the train starts, the corresponding alarm message is determined according to the latest gap detection result and the switch and locking status of the platform door, and the alarm message is sent to the train control system, so that the train control system determines the obstacle detection result according to the alarm information and the gap detection result.
