Abstract

Système (100) ; et procédé associé, de communication filaire décentralisé d’une pluralité de dispositifs (10, 20, 30, 40) via un canal (90) commun sur lequel transite un signal porteur de données transmises sous forme de trames (1, 2, 3, 4), les trames (1, 2, 3, 4) incluant des symboles de signature (1a, 2a, 3a, 4a),chaque dispositif (10, 20, 30, 40) mettant en œuvre une écoute (102) du signal transitant sur canal (90) visant à reconnaitre des symboles de signature (1a, 2a, 3a, 4a),l’un au moins des dispositifs (10) mettant en œuvre une mesure (103, 104) du signal, l’état d’occupation déterminé (105) étant dépendant des résultats de ladite mesure au moins en l’absence de reconnaissance de symbole de signature dans le signal écouté. Figure de l’abrégé : Figure 1System(100); and associated method for decentralized wired communication of a plurality of devices (10, 20, 30, 40) via a common channel (90) over which passes a signal carrying data transmitted in the form of frames (1, 2, 3, 4), the frames (1, 2, 3, 4) including signature symbols (1a, 2a, 3a, 4a), each device (10, 20, 30, 40) implementing listening (102) of the signal passing through channel (90) aimed at recognizing signature symbols (1a, 2a, 3a, 4a), at least one of the devices (10) implementing a measurement (103, 104) of the signal, the state of the determined occupation (105) being dependent on the results of said measurement at least in the absence of signature symbol recognition in the listened signal.
