Abstract

An explosive detection system may include a suction nozzle having a suction port for introducing air containing explosive particles at one end thereof, a discharge nozzle having a discharge port for discharging air at one end thereof, a sensing block in which a detection material capable of detecting explosive particles in the air is disposed, a sensor unit for emitting light to the sensing block and outputting a sensing signal, a first guide pipe connected to the other end of the suction nozzle and guiding the air introduced through the suction nozzle to the sensing block in which the detection material is disposed, a suction force generating unit formed at the other end of the discharge nozzle and to suck air through the suction port and to provide a suction force for sucking air into the sensing block and discharging the air to a discharge port formed at one end of the discharge nozzle, a second guide pipe formed between the sensing block and the suction force generating unit and discharging the air introduced into the sensing block by the suction force generated by the suction force generating unit to the discharge port of the discharge nozzle, and a controller for determining whether explosive particles are present in the air using the sensing signal.
