PYRORESOURCES CONNECTION SCHEME Russian patent published in 2019 - IPC F42C11/04 F42D1/55 

FIELD: physics.

SUBSTANCE: invention relates to systems for simulating (initiating) pyro-agents. Device for blasting pyro-means contains an energy source, decoupling diodes, electric blasting networks and keys, half of which are connected to negative polarity of electric blasting networks by the first leads, and the second pins are connected to the negative terminal of the power source, the other half of the keys are connected to the second pins with the positive polarity of the electric explosion networks, the computing device, the outputs of which are connected to the control inputs of the keys, the control circuit, the output of each of which is connected to the corresponding input of the computing device; gating inputs of the control circuits are connected to the corresponding gates of the computing device. Additionally, current-limiting resistors are introduced into it, the first terminals of which are connected to the first inputs of the control circuits and to the cathodes of decoupling diodes, the anodes of which are connected to the positive terminal of the power source; second pins of the current-limiting resistors are connected to the second inputs of the control circuits and to the first pins of the keys in the positive polarity of the electric blasting networks, low-power current source, power terminals of which are connected to the positive and negative terminals of the energy source, the output of the low-power current source is connected to the power terminals of the control circuits, at the same time, a low-power current source is connected by a control input with a computing device.

EFFECT: invention makes it possible to increase the reliability of undermining pyroresources with an optimal number of control circuits.
