| 摘要 |
The invention concerns a bi-directional energy and data transfer device between two circuits (100, 200), characterised in that each of the two circuits comprises: an oscillator (110, 210) for generating an alternating signal (Sa); a microcontroller (120, 220) for generating a binary signal (Sb, S'b) representing said data; a logic circuit (130, 230) for supplying a transfer signal (S, S') by superposing two alternating and binary signals; an interface circuit (140, 240) for transmitting said transfer signal (S, S') from one circuit and for receiving the transfer signal transmitted by the other circuit, said interface circuit comprising a circuit rectifying the received alternating signal; a demodulator (150, 250) for retrieving said binary signal (Sb, S'b) from the transfer signal (S, S'); and one of said circuits comprises a direct current power source connected to said interface circuit. The invention is applicable to electronic locks.
