DEVICE FOR INITIATING UNIFIED PYROTECHNIC DEVICE Russian patent published in 2016 - IPC F42C11/04 

FIELD: blasting.

SUBSTANCE: invention relates to systems for initiation of pyro device. Pyro device blasting instrument contains microcontroller, energy source, keys, and blasting circuits, divided into two groups; at that, one set of keys is made in form of high-current and low-current semiconductor keys, and another set in form of electromechanical switches, each said group comprises control unit and mechanical contact, first output of which is connected via appropriate electric blasting network and diodes to inputs of high-current semiconductor keys, and second output is connected to positive terminal of power source; outputs of all high-current semiconductor keys are combined and connected to negative terminal of power source and to outputs of low-voltage semiconductor keys, inputs of which are connected to outputs of control units of electromechanical keys, inputs of which are combined and connected to positive terminal of power source; microcontroller is connected to control inputs of all keys of first group.

EFFECT: achieved technical result is improvement of operation reliability, as well as reduction of overall dimensions and weight of device.
