CHARGE INITIATORS METHOD AND SYSTEM Russian patent published in 2019 - IPC F42C13/02 F42D1/04 

FIELD: radio engineering; electronics.

SUBSTANCE: invention relates to radio electronics and can be used in initiation equipment, in particular, in on-board equipment, to ensure safety of automation systems operation under conditions of electromagnetic radiation of various nature. In charge initiation system, including laser control unit, laser and initiation unit, connected by fiber-optic communication line, optical shutter is introduced, which consists of a fiber-optic switch, a photoconverter and a triggering circuit interconnected and placed into a single housing, such that the fiber-optic switch is connected to the photoconverter by a fiber-optic communication line, and photoconverter is electrically connected through triggering circuit with fiber-optic switch, in addition, laser is connected by means of a fiber-optic communication line to a fiber-optic switch which is connected through a fiber-optic communication line to an initiation unit. In the charges initiation method, including installation of a fiber-optic line connecting the laser and initiated charges, and control of the actuating light signal of the laser, into fiber-optic line mounted optical gate, including fiber-optic switch, photoconverter and triggering circuit, control light laser signal is fed to fiber-optic switch, then, to the photoconverter, where it is converted into an electric pulse, by means of which the fiber-optic line is closed, after which the actuating light laser signal is supplied to the initiated charges.

EFFECT: high reliability of the initiation system: preventing unauthorized triggering of the initiation system when exposed to electromagnetic radiation of a different nature.
