Abstract: A method and apparatus for fire ventilation and smoke evacuation in a running train tunnel are provided. The method includes: acquiring a traveling position of the train and a fire position on the train detected by the fire positioning device; predicting all possible stop positions of the train next in various sections of a subway tunnel according to a traveling direction and the traveling position of the train; according to the fire position, listing working state options of the air supply and smoke evacuation subsystems at both ends of each stop position, analyzing each working state option, and screening out a target air supply and smoke evacuation subsystem which only carries out smoke evacuation or air supply control from all the air supply and smoke evacuation subsystems; and performing linkage control on the target air supply and smoke evacuation subsystem.
