A SYSTEM FOR VENTILATION AND SMOKE EVACUATION ON SUBWAY TRAIN VEHICLE

摘要

The present invention relates to a subway ventilation and smoke control system, wherein a plurality of air circulators for the forcible or natural intake and discharge of air are provided in an underground space such as a tunnel having a plurality of platforms to be connected to the ground; a train detection unit connected to a control unit is provided on one side of the platforms or the tunnel connected to the air circulators; and a cutoff/filtration injection unit is provided in each tunnel to provide a cutoff or filtration film using a control signal from the control unit when a train is detected by the train detection unit. Therefore, the subway ventilation and smoke control system maintains air quality in the tunnel during the circulation of the train.
