Wherein, transmitting coil is used for launching electromagnetic wave, and five transmitting coils specifically comprise first transmitting coil 31, second transmitting coil 32, the 3rd transmitting coil 33, the 4th transmitting coil 34 and the 5th transmitting coil 35.These five transmitting coils are spiral winding, are placed on the transmitting coil skeleton 37, and this transmitting coil skeleton 37 is installed in the image-reading device 2.Five concrete putting positions of transmitting coil are: the plane at first transmitting coil 31 and the 3rd transmitting coil 33 places is parallel to each other; The plane at second transmitting coil 32 and the 4th transmitting coil 34 places is parallel to each other and all perpendicular to the plane at first transmitting coil 31 and the 3rd transmitting coil 33 places; The plane at the 5th transmitting coil 35 places is vertical with the plane at the 4th transmitting coil 34 places with first transmitting coil 31, second transmitting coil 32, the 3rd transmitting coil 33 respectively.These five transmitting coils are identical spiral winding, and its coil sequence number does not have special implication.By adopting the putting position of this multiple ray circle and single receiving coil, can guarantee receiving coil no matter have which kind of at random towards, it all can not be simultaneously perpendicular to five transmitting coils, promptly all can have the electromagnetic wave of at least one transmitting coil emission to be received by this receiving coil at any time, this has also just guaranteed reliable and has had isotropic wireless energy transfer.The matching network that connects with transmitting coil is for to be in series or electric capacity in parallel with transmitting coil, and its effect is to make transmitting coil work in resonant condition, and the wireless energy transmission efficiency of transmitting coil under resonant condition is higher.
After image acquisition and memory device 1 collection and having stored image, need put it in the wireless energy discharger 3, because the transmitting coil skeleton has occupied five planes of energy discharger locus, therefore, go up the plane and put into and take out for one that reserves for image acquisition and memory device.
Adaptation control circuit 36 is used for controlling five transmitting coil launching electromagnetic waves that the transmitting coil wireless energy transmission efficiency is the highest.Wherein, adaptation control circuit 36 comprises voltage detection module 361 and control module 362; Voltage detection module 361 is used for detecting respectively the magnitude of voltage at five transmitting coil two ends; Control module 362 is connected the transmitting coil that voltage change ratio is the highest in five transmitting coils according to the magnitude of voltage of voltage detection module 361 detected five transmitting coils with the input electric energy.Voltage detection module 361 comprises envelope detection circuit 3611 and A/D converter 3612; Envelope detection circuit 3611 is used for detecting respectively the magnitude of voltage at five transmitting coil two ends; A/D converter 3612 is used for digital control circuit is changed and transferred to the detected voltage signal of envelope detection circuit; Control module 362 comprises digital control circuit 3621 and MUX 3622; Digital control circuit 3621 control MUX 3622 make the transmitting coil that voltage change ratio is the highest in five transmitting coils be connected with the input electric energy.
