As a key safety protection device at the edge of rail transit platforms, the platform screen door not only effectively alleviates the wind pressure effect caused by high-speed train passage through stations but also significantly reduces the risk of passengers accidentally falling, enhances the overall aesthetic appeal of the platform environment, and lowers the energy consumption of the station. With the continuous deepening of the “Integration of transit networks” strategy, new operational scenarios such as cross-line mixed running trains and multiple trains sharing the same line have emerged in rail transit operations. Traditional platform screen doors face new challenges in terms of adapting to distributed positions, compatibility with vehicle-ground interaction, and equipment energy consumption. To address these issues, this study proposes an innovative fully mobile adaptive platform screen door system control scheme, introducing a particle swarm intelligence algorithm to optimize the control strategy and designing a universal interface solution compatible with CTCS2/3 + ATO and CBTC signaling systems. The research also verified the effectiveness and reliability of the proposed scheme through prototype development and system testing. The research results can effectively enhance the safety level of platforms under the “Integration of transit networks” background, while reducing the area of equipment rooms by 30% and lowering the usage of cables, thereby reducing the costs of civil construction and power supply.
