Abstract

In subway stations with high passenger traffic, using Platform Screen Doors(PSD) is one of the best ways to increase the safety of passengers on the platform. Preventing the passenger from falling on the rails and colliding with the train, which is one of the most common problems in crowded stations, and also the possibility of increasing the speed of the train at the entrance to the station, etc., is met by installing PSD. When the train enters the station, the train doors are placed in front of the PSD and after determining the correct operation of the train station in front of the PSD, the doors are allowed to open. Due to the increase in the speed of trains along the route with the least possible time, increasing the accuracy of train braking when stopping in front of the PSD at the station is of particular importance. Various systems in the world have been designed and implemented to control train brakes when entering stations with train door guards, each of which in turn has strengths and weaknesses. However, the main disadvantage observed in these systems is the lack of resistance to various disturbances and their effect on the braking accuracy of the train. Appropriate stop of the train at the station automatically, taking into account all environmental conditions and possible disturbances.
