Precision pyrotechnic display system and method having increased safety and timing accuracy
A system and method are disclosed for controlling the launch and burst of pyrotechnic projectiles in a pyrotechnic, or “fireworks”, display.
1. An ignitor for a pyrotechnic projectile of the sort comprising a lift charge to be ignited by an electrically operated lift charge ignition device, and a break charge to be ignited by an electrically operated break charge ignition device, said ignitor comprising:
an electronic control module for wirelessly receiving a wireless electronic fire command from a wirelessly connected external control device and, in response thereto, (1) activating said electrically operated lift charge ignition device, and (2) a pre-determined time after wirelessly receiving said electronic fire command from the wirelessly connected external control device, activating said electrically operated break charge ignition device.
2. An ignitor according to claim 1 wherein said electronic control module comprises:
a first output connecting said ignitor to said electrically operated lift charge ignition device;
a second output connecting said ignitor to said electrically operated break charge ignition device;
a power supply for selective connection to said first output and said second output for selectively activating said electrically operated lift charge ignition device and said electrically operated break charge ignition device, respectively; and
a timer for determining when said power supply activates said electrically operated lift charge ignition device and said electrically operated break charge ignition device.
3. An ignitor according to claim 1 wherein the electronic control module can wirelessly transmit data from the ignitor to the wirelessly connected external control device.
4. An ignitor according to claim 1 wherein the pre-determined time is set upon receiving confirmation of a successful launch of the pyrotechnic projectile.
5. A pyrotechnic projectile system comprising:
a pyrotechnic projectile and a wirelessly connected external control device;
said pyrotechnic projectile comprising:
a lift charge;
an electrically operated lift charge ignition device for activating said lift charge;
a break charge;
an electrically operated break charge ignition device for activating said break charge; and
an ignitor comprising an electronic control module for wirelessly receiving a wireless electronic fire command from the wirelessly connected external control device and, in response thereto, (1) activating said electrically operated lift charge ignition device, and (2) a pre-determined time after wirelessly receiving said electronic fire command, activating said electrically operated break charge ignition device.
6. A pyrotechnic projectile system according to claim 5 wherein the electronic control module can wirelessly transmit data from the ignitor to the wirelessly connected external control device.
7. A pyrotechnic projectile system according to claim 5 wherein the pre-determined time is set upon receiving confirmation of a successful launch of the pyrotechnic projectile.
