Method for managing a data transfer system comprising - a plurality of peripheral devices, - a central base, the data transfer system also comprising radiofrequency communication means enabling data to be transferred between the peripheral devices and the central base, the method being characterized in that - energy is recovered on the peripheral devices, and - at least a portion of the recovered energy is transferred to the central base via the radiofrequency communication means, the central base comprising an antenna tuned to a predetermined frequency, the peripheral devices comprising a double-loop antenna having a zero mutual impedance, a first loop handling the transmission of a radiofrequency signal and a second loop handling the reception of a radiofrequency signal, the synchronization of the radiofrequency signals transmitted by the plurality of antennas comprising the following steps: - when the process of communication from the peripheral device to the central base is triggered, a listening phase is implemented by the loop of the antenna configured to receive a radiofrequency signal in order to detect any radiofrequency signal transmitted by the central base, - if a radiofrequency signal transmitted by the central base is detected, the peripheral device then uses the detected radiofrequency signal to transmit, to the central base, a radiofrequency signal that is synchronous and in phase with the detected radiofrequency signal, - if no radiofrequency signal transmitted by the central base is detected, the peripheral device then transmits a radiofrequency signal at the predetermined frequency, - when the central base receives a radiofrequency signal transmitted by a peripheral device at the predetermined frequency, it recovers the received radiofrequency signal and retransmits a radiofrequency signal at the predetermined frequency to the peripheral devices, the synchronization of the radiofrequency signals enabling a simultaneous energy transfer from the peripheral devices to the central base without having any mutually destructive effect between the radiofrequency signals. -
