| 摘要 |
The invention relates to a system for communicating by means of high-frequency PLC carrier currents over a driving line (8), in order to exchange information between two independent assemblies (2, 4), comprising, at each end, a subassembly (30) for transmitting high-frequency PLC carrier currents, and a termination impedance component (32), said driving line further transmitting, to one of said assemblies which is a receiver (4), a low-frequency square-wave PWM signal that provides information, in particular via the width of the voltage intervals thereof, characterized in that each termination impedance component (32) consists of a circuit that is connected to the ground and comprises a capacitor (36) and a resistor (38) arranged in series, or of any electronic circuit that is closely similar thereto. |
