Title
(EN) CIRCUITS AND METHODS FOR CURRENT DRAIN OF A BATTERY FOR WIRELESS SENSOR DATA TRANSMISSION
(FR) CIRCUITS ET PROCÉDÉS DE DRAINAGE DE COURANT D'UNE BATTERIE POUR TRANSMISSION DE DONNÉES DE CAPTEUR SANS FIL
Abstract
(EN)
Disclosed is a circuit including a sensor, a battery and a reservoir capacitance, the sensor being configured to generate sensor data and the capacitance being provided by one or more discrete capacitors. A first circuit component is configured to drain current from the battery to the reservoir capacitor to store energy in the reservoir capacitor at a safe rate. The safe rate does not adversely affect the battery's life. A second circuit component is configured to generate a series of data packets including sensor data at particular time intervals. A third circuit component is configured to transmit the series of data packets with the stored energy of the reservoir capacitor so that the transmitting does not drain the reservoir capacitor of all stored energy.

L'invention concerne un circuit comprenant un capteur, une batterie et un condensateur réservoir, le capteur étant configuré pour générer des données de capteur et le condensateur étant constitué par un ou plusieurs condensateurs discrets. Un premier composant de circuit est configuré pour drainer un courant de la batterie vers le condensateur réservoir afin de stocker de l'énergie dans le condensateur réservoir à un régime sans danger. Le régime sans danger n'a pas d'effet négatif sur la durée de vie de la batterie. Un deuxième composant de circuit est configuré pour générer une série de paquets de données comprenant des données de capteur à intervalles de temps particuliers. Un troisième composant de circuit est configuré pour transmettre la série de paquets de données à l'aide de l'énergie stockée dans le condensateur réservoir, de manière que l'émission ne draine pas toute l'énergie stockée du condensateur réservoir.
