Analysis of Platform Door Interconnection Scheme Based on Door Control Cabinet

The signal and platform door interface solution of Changzhou Rail Transit is analyzed and compared with the conventional interface solution. Interface solution between signal system door control cabinet and platform door is expounded. On-board signal system sends control commands directly to the door control cabinet (SPSDC) through vehicle-ground wireless communication. The intermediate relay control part is canceled and the interface device is simplified. The system reaction time is reduced and the efficiency of door opening and closing is effectively improved. At the same time, the door control cabinet adopts redundant configuration, which improves the operation efficiency and reliability of the entire system.
