Simulation analysis of platform screen door control system in rail transit

This article is based on the design and implementation of a PLC based urban rail transit screen door control system. This system uses PLC as the control core, and monitors the status and position of the screen door in real-time through sensors, achieving control commands such as opening, closing, and pausing the screen door. This system uses configuration software, which can achieve real-time monitoring, control instructions, alarm information, historical data, parameter settings, interface design, and data analysis of the system. By designing and implementing the system, the safety and stability of urban rail transit platforms can be improved, ensuring the safety of passenger travel.
