The launching module units 20 may directly ignite fireworks by supplying electrical signals through an igniter connected to the fireworks launching units 10,

For example, the launching module units 20 may ignite the fireworks by receiving the digital launching signal transmitted by the central control unit 30 through a wired or wireless communication system and supplying an electric current directly to the fireworks launching units 10 according to the digital launching signal. In addition, the launching module units 20 may check whether the electric current correctly flows to the fireworks launching units 10, and transmit a check result to the central control unit 30 in real time. The central control unit 30 may monitor the launching module units 20 in real time.

The central control unit 30 may include a monitoring unit 31 to monitor the fireworks launching units 10 and the launching module units 20, a system control unit 32 to control the fireworks launching units 10 and the launching. module units 20 in real time, and a command unit 33 to launch fireworks of the fireworks launching units 10 by transmitting tine digital launching signal to the launching module units 20.

In addition, the central control unit 30 may remotely transmit or receive data with respect to the launching module units 20 through the wired or wireless communication system. Also, the central control unit 30 may transmit the digital launching signal to the launching module units 20 and receive state information of the launching module units 20.

For example, the central control unit 30 may include the monitoring unit 31, the system control unit 32, and the command unit 33, and the monitoring unit 31 may monitor whether the fireworks launching units 10 and the launching module units 20 operates normally or abnormally in real time.

The central control unit 30 may transmit the launching signals by the launching module units 20 and the wired or wireless communication system. The launching module units 20 may receive the launching signals and may be operated according to the launching signals to ignite the fireworks launching units 10.

In the launching S40, the launching module units 20 may supply an electric. current to the fireworks launching units 10 according to the launching signals, thereby igniting and launching the fireworks launching units 10. Here, the launching module units 20 may transmit a launching completed state to the central control unit 30. The central control unit 30 may monitor a launching state of the fireworks launching units 10.

In the checking S50, the emergency unit 40 checks the launching module units 20 and the fireworks launching units 10 independently from the central control unit 30. Here, the emergency control unit 40 may be connected. with the launching module units 20 through the wired or wireless communication system, and may cheek the progress of launching of the fireworks launching units 10.

In the re-launching or stopping S60, a re-launching signal may be transmitted to the launching module units 20 to ignite the fireworks launching units 10 again when the fireworks launching units 10 misfires as a result of checking by the emergency control unit 40. Therefore, the launching module units 20 may apply the electric current to the firework launching 10 again or interrupt power supply of the launching module units 20 to stop launching.

According to the aforementioned configuration and method, misfire of the fireworks may be reduced during fireworks displays. In addition, since transmission of encoded data and remote control is performed through a bidirectional wired or wireless communication system is used, the fireworks displays may be carried out more safely.
