Interlocked control and interface safety between train door and PSD

열차 출입문과 PSD간 연동제어 및 인터페이스 안전성 확보

A PSD which cooperates with train door provides safety and convenience for passengers. In order to cooperate with train door, the PSD should interface between the PSD control system and the control units of train door. This interface is generally performed in signaling system(ATC/ATO), however, the lines which don't have the interface functionality in the signaling system, it is required to have additional "PSD inter face system" to communicate between train and PSD. In this paper, we propose a safe PSD interface methodology by discussing interlocked control between train door and PSD, recognition of accuracy stop point, troubleshooting logic and log of troubles and driver panel which are adopted in Inchon line1.
