Use of urban train platforms (psd), at metro stations

Abstract

In underground carriageways and highway railways, a permanent one is a lack of adequate safety for passengers at the edge of the platform to solve this problem, the use of Platform Screen Door has become commonplace. The use of PSD is a new way of coordinating doorways and railways doors, by providing a new algorithm, it improves the efficiency of the existing system, and it is very useful in optimizing the energy, taking into account the reduced time of take-off and landing of passengers. One of the prevention measures is the use of automatic PSD doors at metro stations, trains and, if possible, bus stations. PSD systems for ease of access in emergencies such as fire and smoke accumulation inside the tunnel, station, wagon, etc., In addition to the manual release mechanism that is intended for automatic doors, Emergency exit doors are installed next to the automatic doors. Emergency exit doors are designed and constructed in the same way as other parts of the PSD, and the appearance of a station cloth is maintained. PSD doors are usually used on the subway station and the urban trains, preventing passengers from getting too close to the vehicles while on the move and whenever the train is completely stopped, these doors will open and passengers will be allowed to transit, and a few seconds before the train is restarted to ensure that there is no passenger near the train while on the move. In crowded and crowded situations, TVs come with the help of drivers in order to prevent any interruption in system operation and in case of power outage and major electrical supply disruptions, in addition to the backup battery, it is possible to connect the system to UPS. Therefore, under any conditions, the operation of these doors will not be disturbed
