    • The present invention provides an inductive transmission system for inductive transmission of power and full duplex data signals between a first device (1) and a second device (2). The transmission system comprises: —a bi-directional inductive channel (6) between the first device (1) and the second device (2), —first transmission means (121) for transmitting a power signal at a first frequency from the first device (1) to the second device (2) over the inductive channel (6)—a first modulating device (21) for modulating a first data signal at a first modulation frequency, —a second modulating device (15) for modulating a second data signal at a second modulation frequency, —second transmission means (124) for transmitting the modulated first data signals from the first device (1) to the second device (2) over the inductive channel (6), and for transmitting the modulated second data signals from the second device (2) to the first device (1) over the inductive channel (6), wherein the first modulation frequency and the second modulation frequency are at least a factor two apart, and wherein the transmission system furthermore comprises signal cancellation means or compensatio circuit for compensating for the sent data signal, providing a full duplex path without interference from the own sent signals at a device side.
    • 本发明提供一种感应传输系统,用于在第一设备(1)和第二设备(2)之间感应传输功率和全双工数据信号。 传输系统包括: - 在第一设备(1)和第二设备(2)之间的双向感应通道(6), - 第一传输装置(121),用于以第一频率从第一设备 (1)到所述感应通道(6)上的第二设备(2) - 用于以第一调制频率调制第一数据信号的第一调制设备(21), - 用于调制第二数据的第二调制设备(15) 信号,第二调制频率, - 第二传输装置(124),用于通过感应信道(6)将调制的第一数据信号从第一装置(1)发射到第二装置(2),并用于发送调制的第二数据 通过感应通道(6)从第二设备(2)到第一设备(1)的信号,其中第一调制频率和第二调制频率至少是因子二相分离,并且其中传输系统还包括 s信号消除装置或补偿电路,用于补偿发送的数据信号,提供全双工路径,而不受来自设备侧的本身发送的信号的干扰。
