| 摘要 |
The invention concerns an interface device of bi-directional connection of currents carrying low voltage/radiofrequency. It comprises a module for coupling currents carrying low voltage/radiofrequency delivering in reception signals (rcp) representing reception of carrier currents, a first channel (I) of currents carrying low voltage/radiofrequency delivering a signal modulating radiofrequency transmission (sme). A coupling device (2) receives in transmission the modulating signal (sme) for transmitting a radiofrequency signal (srfe) representing the carrier currents, and, in reception, a reception radiofrequency signal (srfr) transmitted to a second channel (II) of currents carrying low voltage/radiofrequency. The second channel (II) delivers signals (ecp) representing the carrier currents in transmission to the module (1) for transmission of the low voltage line. The invention is useful for house automation and for managing subscriber services. |
