Abstract
(EN)
This transmitter is provided with: an electric power source for the transmitter; a state detection unit that detects the state of a tire; a data generation unit that generates transmission data including tire state data indicating the state of the tire detected by the state detection unit; a transmission unit that modulates the transmission data so as to transmit the data; a storage unit that stores correspondence relations obtained by assigning specific bit values, among transmission data bits changing along with rotation of a wheel, to a plurality of specific angles set to a wheel rotation angle; and a transmission control unit that, when it is detected that the wheel rotation angle is a specific angle, transmits the transmission data from the transmission unit.
(FR)
L'invention concerne un émetteur comprenant : une source d'énergie électrique qui lui est destinée ; une unité de détection d'état qui détecte l'état d'un pneu ; une unité de génération de données qui génère des données de transmission comprenant des données d'état de pneu indiquant l'état du pneu détecté par l'unité de détection d'état ; une unité de transmission qui module les données de transmission de façon à transmettre les données ; une unité de stockage qui stocke des relations de correspondance obtenues par attribution de valeurs de bits spécifiques, parmi des bits de données de transmission changeant avec la rotation d'une roue, à une pluralité d'angles spécifiques fixés à un angle de rotation de roue ; et une unité de commande de transmission qui, lorsqu'il est détecté que l'angle de rotation de roue est un angle spécifique, transmet les données de transmission à partir de l'unité de transmission.
