Title
(EN) METHOD AND SYSTEM FOR MANAGING DATA TRANSMISSION FROM A PLURALITY OF SENSOR DEVICES INCLUDED IN A TYRE
(FR) PROCÉDÉ ET SYSTÈME DE GESTION DE TRANSMISSION DE DONNÉES À PARTIR D'UNE PLURALITÉ DE DISPOSITIFS DE DÉTECTION SITUÉS DANS UN PNEUMATIQUE
Abstract
(EN)
Wireless transmission from sensor devices included in tyres is coordinated by a receiving unit associated with the tyre, or transmission coordinator. In more detail, every sensor device is made aware of an overall time window available for transmission, and based on at least this information it calculates a dedicated timeslot for the transmission of its data within such time window. This coordinated transmission makes possible a strong reduction of the probability of collisions and transmission errors, and reduces the number of transmissions, so as to comply with the limited power resources available at each sensor device.
(FR)
La transmission sans fil à partir de dispositifs de détection situés dans des pneumatiques est coordonnée par une unité de réception associée au pneumatique ou un coordinateur de transmission. De façon plus détaillée, chaque dispositif de détection a conscience d'une fenêtre de temps générale disponible pour la transmission, et sur la base d'au moins cette information, il calcule un intervalle de temps dédié pour la transmission de ses données dans une telle fenêtre de temps. Cette transmission coordonnée permet une forte réduction des risques de collisions et des erreurs de transmission, et réduit le nombre de transmissions, de manière à se conformer aux ressources de puissance limitées disponibles dans chaque dispositif de détection.
