DEVICE FOR DETONATING PYRO-PRODUCTS Russian patent published in 2021 - IPC F42D1/55 

FIELD: pyro-products initiation systems.

SUBSTANCE: invention relates to pyro-product initiation systems. The device for detonating pyro-products contains a microcontroller, each output of which, except for the last one, is connected to the control input of each relay key, and the last output is connected to the control input of the electronic key, normally open contacts of the relay keys are connected to the first outputs of the electric explosive networks, the energy source, to the negative the terminal of which is connected to the first output of the electronic key, the second output of which is connected to the movable contacts of the relay keys. Additionally, control circuits are introduced, the number of which corresponds to the number of relay keys, each of which has a normally closed contact connected to the first input of the corresponding control circuit. The second inputs of the control circuits are connected to the negative terminal of the power source, and the outputs are connected to the inputs of the microcontroller, which is connected by inputs/outputs to the interface module connected to the information transmission line.

EFFECT: functioning reliability improvement.
