FIELD: blasting operations.
SUBSTANCE: data transmission device for contact-less programming of operating modes of gas-dynamic pulse device initiator relates to devices for contact-less programming and data transmission to gas-dynamic pulse device initiator with inductive control circuit. Device comprises outer body with hole for magnetic flux output, wherein oscillating circuit, master oscillator, power amplifier control circuit, power amplifier, and modulator are arranged. Adjusted clock generator is connected in series to power amplifier control circuit, power amplifier, and oscillatory circuit containing radiating coil, connected in series to capacitor. Core is made of ferromagnetic material with high magnetic permeability and high saturation induction, and has shape of partial ring installed in order to direct radiation of magnetic field into location area of receiving inductance coils of gas-dynamic pulse device. Planes of core end faces are arranged parallel or at angle to each other. Power amplifier is formed as bridge circuit with powerful MOS-transistors. Parallel to adjusted clock generator, modulator of bearing frequency is connected to power amplifier control circuit, having input for control signal input.
EFFECT: technical result is simplified design and higher operation efficiency of device.
