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.

Abstract: The present disclosure relates to an automatic control type hot smoke testing system which includes a fire source system, a smoke generation system and a control system. The fire source system is used for generating fire source and includes a first tank and several liquid fuel atomizing jet burners, wherein the first tank includes an air tank which is used for providing air and a fuel control tank which is used for controlling valves, distributing fuel and inspecting flame of the burners. The smoke generation system is used for generating smoke and includes a second tank, a smoke outlet pipe, smoke cake clamps and smoke cake turntables. Smoke cakes are initially placed in the smoke cake clamps, then moved to an ignition position one by one by for ignition, and finally rotated to through hole positions of a smoke generation box to fall into the smoke generation box by the servo motor. The control system is used for controlling the fire source system and the smoking generation system.
