Process for transmitting messages, and functional unit and connected thereto.

摘要

Each messages (31) comprises an initial transmission (41) and two transmissions are repetitive (51), all identical. The initial transmission (41) begins after a period of silence (ts m) has been detected on the communication space. & br / the period of silence (s1) between the emissions (41, 51) varies as a function of the functional unit emitting. Thus, if a message (32), a transmission (42) at the same time (t1) that the emission (41) of the first message (31), the collision, which results in only to the initial transmission because, during the emission repetitive, the functional unit which is to detect the period of silence the longest (s2) detects the activity resulting from the emission repetitive (51) of the other unit before being able to start its own emission repetitive (52). Thus, the message associated with the period of silence the longer is displaced until the message is finished. & br / use in order to manage collisions reliable, economical, without loss of time and without centralizing means.
