CONTROL SYSTEM OF PYROTECHNIC DEVICES Russian patent published in 2015 - IPC F42D1/55 

FIELD: blasting operations.

SUBSTANCE: invention relates to initiating devices for detonation of pyrotechnic devices. The control system of pyrotechnic devices comprises the pyrotechnic devices made with the use of electric-igniting bridges, the external power source, the key elements K1…Kn, the first outputs of which are connected to the first terminals of the said bridges, the control unit which outputs are connected to the control inputs of the key elements K1…Kn, and the analogue-to-digital converter which output is connected to the input of the control unit. The following is built-in: the constant current source, the switch with two states, connected by the first and second inputs of the first state to the first and second outputs of the external power source, by the first and second inputs of the second state to the first and second outputs of the constant current source and the first and second inputs of the analogue-to-digital converter, and by the first and second outputs, respectively, to the first and second inputs of the key elements K1…Kn, and the current-driving resistors mounted between the second outputs of the elements K1…Kn and the second terminals of the bridges, at that the control input of the switch is connected to the corresponding output of the control unit.

EFFECT: increasing safety and reliability, enhancing functional capabilities of the device.
