Abstract:
An interface device for a bi-directional low voltage/radio frequency carrier LC-LV connection between a low voltage electrical energy distribution line, allowing the transmission of signals by carriers, and radio space, characterized in that this comprises:LC-LV coupling means interconnected to said low voltage line and allowing to deliver, during reception of the first representative signals of information during reception of said carriers:a first low voltage/radio frequency carrier channel comprising at least:first transformation means of said first representative signals of information during reception of said carriers into a first intermediate frequency signal amplitude modulated by said first representative signals of information during reception of said carriers;first frequency transposition means of said first intermediate frequency signal into a radio frequency transmission modulation signal;a coupling and radio frequency transmission-reception device interconnected to said first frequency transformation means and receiving on the one hand, during transmission, said radio frequency transmission modulation signal to carry out the transmission of a representative radio frequency signal of the information of said carriers, and, on the other hand, during reception, a radio frequency reception signal, said interface device including moreover, interconnected to said coupling and transmission-reception device;a second radio frequency/low voltage carrier channel receiving said radio frequency reception signal and including at least:second frequency transposition means of said radio frequency reception signal into a second intermediate frequency signal of the same frequency as that of the first intermediate frequency signal;second transformation means of the second intermediate frequency signal into second representative signals of information during transmission of said carriers, said second transformation means being interconnected and delivering said second representative signals of information during transmission of said carriers to said LC-LV coupling means, for transmission of this information in the form of carriers on the low voltage line.
