Timing Design and Commissioning Scheme for Linkage between Urban Rail Transit Electric Passenger Car Doors and Platform Doors

Objective Realizing the synchronous linkage between electric passenger car doors and platform doors (hereinafter referred to as "car-platform doors") in urban rail transit can further improve the metro operation efficiency, so it is necessary to study its linkage timing design and commissioning scheme. Method Combined with the survey results of the current situation in the industry and the analysis of passengers inertial behavior in the door opening and closing scenarios, the design idea of car-platform doors linkage control is proposed. Based on the in-depth study of the transmission characteristics of the door opening and closing instructions and the system delay, the control timing of car-platform doors linkage in the signal mode is designed. Result & Conclusion The feasibility of the linkage timing and commissioning scheme for the car-platform doors linkage is verified through the joint commissioning test, so as to realize the macro-synchronous car-platform doors linkage, which has been promoted and applied in five lines of Chengdu Metro.
