Method and apparatus for fire ventilation and smoke evacuation in running train tunnel

An apparatus for fire ventilation and smoke evacuation in a running train tunnel, comprising:

• an acquisition module, configured to, in a case where a fire positioning device detects a fire of a train, acquire a traveling position of the train and a fire position on the train detected by the fire positioning device;
• a predicting module, configured to predict 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;
• a computing module, configured to, according to the fire position, one the basis of a control principle of carrying out smoke evacuation by an air supply and smoke evacuation subsystem in a positive direction of a fire point and carrying out air supply by an air supply and smoke evacuation subsystem in an opposite direction of the fire point, list working state options of the air supply and smoke evacuation subsystems at both ends of each stop position, analyze each working state option, and screen out a target air supply and smoke evacuation subsystem which only carries out smoke evacuation or air supply control from all of the air supply and smoke evacuation subsystems;
• and
• a control module, configured to perform linkage control on the target air supply and smoke evacuation subsystem according to the working state option corresponding to the target air supply and smoke evacuation subsystem;
• wherein a subway tunnel between two adjacent stations is sequentially divided into a plurality of sections, each section is provided with a fire positioning device and an air supply and smoke evacuation subsystem, and the target air supply and smoke evacuation subsystem is any one of the plurality of air supply and smoke evacuation subsystems.
