Multi-zone smoke detector for vehicle and fire extinguishing system including the same

A fire extinguishing system for a vehicle comprising:

• a plurality of smoke suctioning and fire extinguishing fluid discharge pipes, each of the plurality of smoke suctioning and fire extinguishing fluid discharge pipes being positioned in each of a plurality of fire monitoring zones provided in the vehicle, and each of the plurality of smoke suctioning and fire extinguishing fluid discharge pipes having a nozzle for spraying a fire extinguishing fluid;
• a plurality of smoke detection pipes connected to the plurality of smoke suctioning and fire extinguishing fluid discharge pipes through a control valve to selectively communicate with the plurality of smoke suctioning and fire extinguishing fluid discharge pipes;
• an air compressor configured to apply suction pressure to the plurality of smoke detection pipes;
• a multi-zone smoke detector configured to detect smoke in air flowing in through the nozzle and the plurality of smoke suctioning and fire extinguishing fluid discharge pipes from each of the plurality of fire monitoring zones by the suction pressure of the air compressor acting on the plurality of smoke suctioning and fire extinguishing fluid discharge pipes through the plurality of smoke detection pipes;
• a controller configured to determine that a fire occurs when the smoke is detected through the multi-zone smoke detector, and to output a control signal for spraying the fire extinguishing fluid to one of the plurality of fire monitoring zones where the fire occurs through the nozzle;
• and a fire extinguishing fluid supply device configured to supply the fire extinguishing fluid to the plurality of smoke suctioning and fire extinguishing fluid discharge pipes within the fire monitoring zone where the fire occurs according to the control signal output from the controller.
