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.
