Method and system for data transmission on a power line

Abstract

Abstract 1. A method of sequentially transmitting data, in which use is made for data transmission of a line extending from a main supply circuit which supplies at least one peripheral circuit with energy, in which method the main circuit brings about a short decrease of the supply voltage for the transmission of a bit to the peripheral circuit, characterized in that the main circuit not only reduces the voltage, but also linits the current susceptible to be supplied to the line, in that it continues to limit this current whilst the voltage remains reduced, and in that, for transmitting an information originating from a peripheral circuit to the main circuit the said peripheral circuit causes the reduction of the voltage of the line to be prolonged after the main circuit has stopped to bring about this reduction.
