[0002] Rail transit refers to a type of transportation tool or transportation system in which operating vehicles need to travel on specific tracks, including railways, subways, light rail, etc. Rail transit usually has a track area and a platform. Passengers wait for trains on the platform, and trains travel in the track area. The platform door is set between the platform and the track area to isolate the platform from the track area, which can prevent passengers from accidentally or intentionally entering the track area, and prevent foreign objects from falling into the track area and affecting the normal operation of the train; it can prevent passengers from being sucked by the strong negative pressure generated by non-stop trains running at high speeds, causing tragedies; it can also reduce the load of the air-conditioning system in the station, block the airflow in the track area, reduce the resistance during the train's travel, and prevent the air on the platform from entering the track area. It can be seen that platform doors play an important role in rail transit.
