FIELD: technology for organization of communication channels using three-phased electric network. ^ SUBSTANCE: input of device on transmitting side is connected to input/output port through serially connected interface, coder, modulator, generator of sinusoidal signal, power amplifier and block for synchronization with electric network. On receiving side input/output port is connected to output of device through serially connected electric network synchronization block, filter, amplifier, sinusoidal signal transformer, digital filter, demodulator, decoder, and interface. Clock generator is connected in parallel with coder, modulator, decoder, demodulator, digital filter, realized in programmable logic integrated circuit. Programmable logic integrated circuit uses transfer algorithm, making it possible to transform input data to optimal type of signal for transmission via force cables, and receipt algorithm, making it possible to transform signal from electric power network to signal, appropriate for input-output device, connected to proposed device. ^ EFFECT: increased information transfer speed, decreased probability of receipt error, increased communication distance, achieved by usage of multi-frequency modulation in range of frequencies from 100 to 150 kHz. ^ 2 cl, 1 dwg, 2 tbl |
