FIELD: technology for transferring information via electric supply lines, possible use in alarm signaling systems.
SUBSTANCE: in phases of alternating-current electric network selected for transferring code messages, moments of transfer of main harmonic of network voltage over zero are determined with derivative of same sign and time stamps are generated in these moments. In moments of beginning of said stamps synchronization impulses are generated. Exchange of symbolic information is realized between phases of electric network selected for transferring code messages. Resulting series of synchronization impulses is received, providing transport function for transferring information in unified communication network. Exchange of symbolic information between phases of electric network is realized with usage of receiving-transmitting device, made with possible receipt and/or transmission of code messages via phases of alternating-current electric network, or using identical reactive connecting devices.
EFFECT: simplified construction and assembly of information transfer systems at territorially distributed objects.
