DEVICE FOR BLASTING PYROTECHNIC Russian patent published in 2017 - IPC F42D1/05 F42C11/00 

FIELD: blasting operations.

SUBSTANCE: invention relates to the systems of initiation of pyrotechnic in the area of blasting operations. The device for blasting of pyrotechnic comprises a microcontroller, an external power source, the outputs of which are connected to the inputs of the voltage converter, electronic keys K₁…K_n , to the control inputs of which the respective microcontroller outputs and electroexplosive networks are connected, thus further the functioning control system is introduced, a pulse generator, first and second diodes, resistor, voltage regulator, the input start and electromagnetic relays P₁…P_n , windings through the power of the amplifier PA₁…PA_n are connected to the corresponding outputs of the microcontroller, outputs of electronic keys K₁…K_n through the normally open solenoid relay are connected to the first terminals of electroexplosion networks, the second terminals of which are combined and connected to the positive output of the energy source, the negative output of which is connected to the negative bus voltage regulator power supply and the electronic part of the device, the output operation of the control system is connected to the control input of the pulse generator, anti-phase outputs are connected with clock-voltage converter inputs, the minus output of which is connected to an output of the energy source and the positive way through the first diode to the input of the voltage regulator, the output of which is connected to the positive supply rail of the electronic part of the device, run the input through the series-connected second diode and a resistor is connected to the input of the voltage regulator.

EFFECT: increase of the operational safety of the device to blast the pyrotechnic.
