The present invention relates to an apparatus for measuring a muzzle velocity of a fired bullet so that the bullet may explode at an accurate location. The muzzle velocity measuring apparatus includes a detector configured to comprise a pair of cores encircled by probe wound coils and installed in two separate positions in an adapter, and to output a muzzle velocity signal based on eddy current signals which are generated by the probe wound coils when a bullet fired from a bullet chamber passes through the adapter, a muzzle velocity calculator configured to calculate a flight speed of the fired bullet based on the muzzle velocity signal; and a transmitter configured to transmit the calculated flight speed to the bullet. The transmitted data may be used by a controller integrated in the bullet to correct the preset time of explosion.The cores of the coils may have a U-shape.

Fireworks launching system and method are provided, which enable safe and accurate control in launching fireworks. The fireworks launching system may include fireworks launching units which are fireworks prepared for launching, launching module units electrically connected with the fireworks launching units to ignite the fireworks launching units, a central control unit to transmit a digital launching signal programmed in advance to the launching module units, and an emergency control unit operated independently from the central control unit to independently control the launching module units. Accordingly, a launching error such as misfire during fireworks may be reduced. Since launching may be performed accurately in units of maximum 62 microseconds (s), production technique and perfection for the fireworks displays may be increased. In addition, more safe fireworks displays may be carried out launching the fireworks in a remote manner through central control and monitoring using a bidirectional wired or wireless communication system.
