Device for transmission by power-line communication in an aircraft
First Claim
1. A device for transmission by power-line communication between two items of equipment on board an aircraft, the device for transmission by power-line communication comprising a transmission cable connecting the two items of equipment, the transmission cable being configured to simultaneously transmit a power supply and a data signal and comprising two twisted pairs of conductors, wherein the device comprises a data sender comprising a COFDM coupler configured to modulate a signal by carrier modulation according to a COFDM mode, and a data receiver comprising a COFDM coupler configured to demodulate a signal modulated by carrier modulation according to a COFDM mode, and whereinthe data sender is configured to send a test signal by carrier modulation according to a COFDM mode,the data receiver is configured to detect signals corresponding to the sent test signals and analyse the carriers of the detected signal with respect to the sent signal and deduce therefrom the state of the transmission cable.

Abstract
The present invention relates to a device for transmission by power-line communication (1) between two items of equipment (10, 20) on board an aircraft (1), comprising a transmission cable (3) configured to simultaneously transmit a power supply current and a data signal. This cable (3) comprises two twisted pairs of conductors (34, 34a, 34b). The device comprises a data sender (100) comprising a COFDM coupler (44) configured to modulate a signal by carrier modulation according to a COFDM mode, and a data receiver (200) comprising a COFDM coupler (44) configured to demodulate a signal modulated by carrier modulation according to a COFDM mode. The data sender (100) is configured to send a test signal by carrier modulation according to a COFDM mode, while the data receiver (200) is configured to detect signals corresponding to the test signals sent, and to analyze the carriers of the detected signal in regard to the signal sent and deduce therefrom the state of the transmission cable (3).
