Abstract
The present disclosure concerns a system for driving a Venetian blind comprising a blind assembly which comprises a Venetian blind, an electric motor for actuating the movement of said Venetian blind and first electronic means configured to generate a drive signal for driving said electric motor; a control unit having drive means for driving the movement of said Venetian blind, a power source for generating a current signal to power said electric motor and second electronic means that are in signal communication with said drive means and with said power source for controlling said electric motor; a two-wire power line disposed between said control unit and said blind assembly to power said electric motor with said current signal and the first electronic means are in signal communication with said second electronic means via said two-wire power line. The system is characterized in that the first electronic means are configured to generate a first data signal identifying the state of said electric motor and to detect a current signal in said two-wire power line identifying the current value absorbed by said electric motor; said second electronic means are configured to receive said f…
