Method and device for managing information transmission over mains applied to a domestic network

摘要

Several communication stations are connected to the electrical distribution circuit (S) and transmit information over the latter by injecting carrier currents, in the form of frames comprising a predetermined number of bits transmitted sequentially. In the course of transmitting each bit, a bit is received as an echo of the transmitted bit and the echo bit is compared with the transmitted bit. If a collision is detected, the stations involved in the said collision are set into a condition of listening for an information string transmitted over the electrical distribution circuit by the other communication stations respectively according to a predetermined order of priority. Use in high tech domestic communication systems. IMAGE
