State receive lateral coil 104 be placed in the multiple transmission lateral coil 102 it is any send lateral coil 102 induction region when, control
Make any lateral coil 102 that sends and send the wireless energy to the reception lateral coil 104.
By when receiving lateral coil 104 and being placed on the induction region of any transmission lateral coil 102, any sent by above-mentioned
Lateral coil 102 sends wireless energy to lateral coil 104 is received so that can be selected according to the position for receiving lateral coil 104 corresponding
Transmission lateral coil 102 send wireless energy, on the one hand avoid induction region do not include receive lateral coil 104 transmission side line
Circle 102 also sends wireless energy and causes the waste of energy, on the other hand it also avoid reception lateral coil 104 and is in multiple transmissions
The induction region of lateral coil 102, and only by send on a small quantity lateral coil 102 send wireless energy and cause receive the work(of lateral coil 104
The problem of rate deficiency, improve the flexibility of system.
For example：There are two coils sending side, is placed on when receiving lateral coil in the induction region of one of coil
When, if two coils all send wireless energy, the waste of energy can be caused；When reception lateral coil is placed on the sense of two coils
When answering in region, if only coil sends wireless energy, it can cause to receive the underpower of lateral coil, therefore, can be with
The transmission lateral coil for including receiving lateral coil by induction region sends wireless energy, to improve the spirit to sending lateral coil selection
Activity.
In addition, the Transmission system 100 of wireless energy according to the above embodiment of the present invention, can also have what is added as follows

104 are placed on the real time position in the multiple transmission lateral coil 102, to determine any reception according to the real time position
Lateral coil 104.
By detecting the real time position for receiving lateral coil 104 in multiple transmission lateral coils 102, lateral coil can received
When 104 real time position changes, automatic detection and in time switching send the transmission lateral coil 102 of wireless energy, to ensure
How the position for no matter receiving lateral coil 104 changes, and the transmission lateral coil 102 for receiving lateral coil 104 is all included by induction region
Send wireless energy, avoid induction region do not include receiving lateral coil 104 transmission lateral coil 102 also send wireless energy and
The waste of energy is caused, while it also avoid induction region and do not send energy including receiving the transmission lateral coil 102 of lateral coil 104
And the problem of causing to receive 104 underpower of lateral coil.Wherein, position detection unit 108 can be pressure sensor or infrared
Sensor.
According to one embodiment of present invention, the position detection unit 108 is specifically used for：Show in the real time position
It is described reception the whole of lateral coil 104 or predetermined area be in it is the multiple transmission lateral coil 102 in any coil perpendicular to institute
When stating in the view field on the direction of any coil plane, determine that the reception lateral coil 104 is placed on any coil
Induction region.
Because the placement location and placement direction that send lateral coil 102 are not known, therefore by according to reception lateral coil 104
Whether whole or predetermined area are in multiple transmission lateral coils 102 any coil perpendicular to the side of any of the above-described coil plane
Determine that induction region includes the transmission lateral coil 102 for receiving lateral coil 104 in upward view field, can be more accurately
It is determined that need to send the transmission lateral coil 102 of wireless energy.Wherein, predetermined area can be adjusted according to actual conditions.
According to one embodiment of present invention, the position detection unit 108 is specifically used for：Show in the real time position
It is described reception the whole of lateral coil 104 or predetermined area be in it is the multiple transmission lateral coil 102 in any coil perpendicular to institute
When stating in the view field on the direction of any coil plane, the reception lateral coil 104 and any line are further detected
The distance of plane where circle, and when the distance is less than or equal to preset distance numerical value, determine the reception lateral coil 104
It is placed on the induction region of any coil.
Because wireless energy transfer has a certain distance limitation, lateral coil 104 is received with sending the distance of lateral coil 102
More remote, the efficiency of wireless energy transfer is lower.Therefore, by receiving lateral coil 104 in any transmission lateral coil 102 vertical
Directly when in the view field on any direction for sending the plane of lateral coil 102, determine whether and any transmission side line
Whether the distance for enclosing 102 place planes is less than preset distance numerical value, can improve selection to the full extent and send wireless energy
Coil accuracy.
According to one embodiment of present invention, in addition to：Power obtaining unit 110, for obtaining the receiving side in real time
The power to be output of coil 104；Described control unit 106 is additionally operable to：Adjusted according to the acquisition result of the power obtaining unit 110
The quantity of the whole transmission lateral coil 102 that the wireless energy is sent to the reception lateral coil 104.
By being adjusted according to reception lateral coil 104 power to be output to the hair for receiving the transmission wireless energy of lateral coil 104
The quantity of lateral coil 102 is sent, the flexibility that Systematic selection sends the transmission lateral coil 102 of wireless energy can be improved, avoided
When reception lateral coil 104 power to be output is smaller, wireless energy is also sent by more transmission lateral coil 102 and causes energy
Waste, while it also avoid receive lateral coil 104 it is to be output power it is larger when, sent out by less transmission lateral coil 102
The problem of sending wireless energy and causing to receive 104 power output difference of lateral coil.
According to one embodiment of present invention, described control unit 106 is specifically used for：Show in the acquisition result described
When power to be output reduces, reduce any send in lateral coil 102 and send wireless energy to the reception lateral coil 104
The quantity of transmission lateral coil 102；And when the acquisition result shows that the power to be output raises, increase is the multiple
Send the quantity of transmission lateral coil 102 for sending wireless energy in lateral coil 102 to the reception lateral coil 104.
Due to receive lateral coil 104 power output depend on send lateral coil 102 send wireless energy number, and
Under normal circumstances, to the transmission lateral coil more than 102 for receiving the transmission wireless energy of lateral coil 104, receive lateral coil 104 and receive
Wireless energy it is correspondingly more, it is also bigger to receive the power output of lateral coil 104, therefore, is treated receiving lateral coil 104
When power output reduces, it is possible to reduce to the quantity for the transmission lateral coil 102 for receiving the transmission wireless energy of lateral coil 104；And
When receiving the power to be output rise of lateral coil 104, it can increase to the transmission side line for receiving the transmission wireless energy of lateral coil 104
The quantity of circle 102.
According to one embodiment of present invention, in addition to：Rectification circuit 112, the reception lateral coil 104 is connected to, is used
Rectification processing is carried out in the wireless energy received to the reception lateral coil 104.
Rectification processing is carried out to receiving the wireless energy that lateral coil 104 receives by using rectification circuit 112, can be incited somebody to action
Receive the wireless energy that lateral coil 104 receives and be converted to the direct current for being capable of driving load, to ensure the load using direct current
Being capable of normal work.
