Design of door control system for urban railway simulation device

The conventional theoretical explanation and the original car static training mode of the urban rail train door control system are insufficient for trainees to intuitively understand the working principle of the control circuit. Therefore, this paper proposes a 5:1 scale, modular and transparent control circuit design scheme of urban rail train door control system. The scheme consists of three parts: mechanical structure, control circuit and man-machine interface. The mechanical structure implements the layout and linkage of the gating device. The control circuit implements the electrical components in each region. The man-machine interface implements the human-computer interaction function. The scheme integrates the PLC control of the lower computer and the man-machine interface display of the upper computer, achieving the automation of the door control system. The scheme can help trainees to understand the working principle of the door control system more intuitively and accurately, and improve the training mode of urban rail transit technical personnel.
