Abstract:
The invention relates to electrical network communications engineering and can be used in systems for automatic data collection from electric, heat, water, gas meters etc. The technical result is significant simplification of the interior structure of slave units increased noise stability of a system. This result is achieved by using zero crossing points of the fundamental harmonic of system supply line voltage as character synchronization events.
