Fig. 7 is the flow chart of the 3rd embodiment of wireless charging method of reseptance of the present invention.The present invention
3rd embodiment of described wireless charging method of reseptance is applied to radio receiver of the present invention
4th embodiment.
As it is shown in fig. 7, the 3rd embodiment of wireless charging method of reseptance of the present invention includes following step
Rapid:
Step 71: charging equipment detects wireless energy, initially enters wireless charging state；
Step 72: charging equipment gives user images or auditory tone cues, whether inquiry " starts intelligent detecting
Function "；If user selects "No", the most do not start intelligent detecting function, jump to step 79；If user selects
Select "Yes", then start intelligent detecting function, go to step 73；
Step 73: charging process circuit starts to measure produced by each wireless receiving coil of current location and fills
Electricity current value, and charging current value is sent to baseband processing chip；
Step 74: baseband processing chip completes to process charging current value and judge, if algorithm evaluation is now
Charging current has reached maximum, then perform step 75；If algorithm evaluation now charging current not yet reaches
Maximum, then perform step 76；
Step 75: using image or auditory tone cues user " has been optimal charge position, it is not necessary to again move and set
Standby "；Then jump to step 79；
Step 76: use image or auditory tone cues user please to move charging equipment according to certain direction, as
" translation device the most to the left ", inquires whether user " abandons this to move " simultaneously；
Step 77: whether baseband processing chip detection user selects " abandoning this to move ", if it is holds
Row step 79, otherwise performs step 78；
Step 78: if mobile sensor module detection charging equipment is moved, then jump to step 73；
If mobile sensor module detection charging equipment was not moved within the time set in advance, then jump to
Step 79；
Step 79: charging equipment closes prompting, terminates this intelligent detecting.
In the 3rd embodiment of wireless charging method of reseptance of the present invention, if mobile sensor during charging
Module detects that the position of charging equipment changes again, then jump to step 72 and re-start intelligence
Detection.
Illustrate as a example by user carries out wireless charging for mobile phone below, treat that mobile phone enters wireless charging mould
After formula, screen or loudspeaker prompt the user whether to start intelligent detecting pattern.If user selects "No",
Then mobile phone cuts out prompting, the wireless charging state before still maintaining.If user selects "Yes", then mobile phone
Charging process circuit in interior wireless charging receiver is each wireless receiving coil institute in starting to detect mobile phone
The current value produced.These current data are sent the Base-Band Processing core to interior of mobile phone by charging process circuit
Sheet, baseband processing chip completes data and processes, and show that current charge position is the most optimal, i.e. charged electrical
The result of determination whether stream has been maxed out, and give user prompting by screen or loudspeaker.Base band
Process the algorithm in chip and will complete determination processing based on following information: normal charge magnetic field intensity by with
The dampening information of coil distance distance impact, each wireless receiving coil location distribution information on mobile phone,
Coil turn is how many and diameter with generate the percent information of size of current, cell voltage just and charging
The homologous thread information of size of current.
Algorithm realizes process and is exemplified below:
Wireless charging receiver includes five and receives coil, and these five receive coil and lay respectively at mobile phone
Upper left, lower-left, upper right, bottom right, centre position, above-mentioned coil is produced by charging process circuit respectively
Current value complete to measure, then baseband processing chip contrasts according to the number of turn between coil and diameter, will
It is scaled certain and unifies the standard current value under the number of turn and diameter；If upper left and the standard electric of lower-left coil
Flow valuve is more than upper right and the standard current value of bottom right coil, and this numerical value is beyond a certain limit value, then magnetic is described
The decline of field is very fast, and mobile phone is likely to be at the edge zone in magnetic field, and charging current still has the space of increase,
May remind the user that cell phone to the left；If after upper left, lower-left, upper right, the coil conversion of four, bottom right
Standard current value essentially identical, then explanation mobile phone is substantially at the central area in magnetic field, and charging current is
Through reaching maximum, may remind the user that, without cell phone, intelligent detecting process terminates.
Mobile phone feed back to user prompting in move mode with algorithm and receive the position of coil, the number of turn,
The design such as diameter is relevant, and move mode includes translating fuselage, clockwise, main body turning counterclockwise etc..
If baseband processing chip determines needs cell phone, then handset starting mobile sensor module, in order to
Whether detection mobile phone there occurs movement, if being moved, then baseband processing chip transmitting order to lower levels is to juice point
Reason circuit, again receives coil starting current value to each and measures, and baseband processing chip is according to algorithm again
Judge；If secondary judged result is without cell phone, then remind user's optimal charge the most on earth
Position；If secondary judged result is still for not yet to reach optimal charge position, then user can continue to move to
Mobile phone.Sometimes, when multiple charging equipments existing on charging panel occupy a large amount of position, or currently
During charging magnetic field instability, it is also possible to cause cell phone the most for several times still cannot arrive optimal charge
Position, now user can directly select to abandon moving on screen, thus terminates intelligent detecting process.
If additionally, after handset starting mobile sensor module, unidentified in longer period of time move to user
Start machine, close prompting the most equally, terminate intelligent detecting process.And in charging process thereafter, one
Denier mobile sensor module detects that mobile phone there occurs movement, can again ask the user whether to start intelligence spy
Survey pattern.
Present invention also offers a kind of wireless terminal, including above-mentioned wireless charging receiver.Specifically
During enforcement, described wireless charging receiver is preferably integrated in described wireless terminal, the most described wireless
Cue generation module and current detecting control module that charging receiver includes can be arranged at wireless
In the baseband processing chip that terminal carries.
Wireless charging receiver of the present invention, wireless charging method of reseptance and wireless terminal, pass through
Whether detection wireless terminal putting position in magnetic field makes the wireless receiving being installed on this wireless terminal
Charging current in coil reaches to maximize, and then reminds user to adjust the position of wireless terminal accordingly
Whole, clear logic, simple in construction, it is easily achieved, charge efficiency can be promoted, provide the user facility.
Described above it is merely exemplary for the purpose of the present invention, and nonrestrictive, ordinary skill
Personnel understand, in the case of the spirit and scope limited without departing from claims, can make perhaps
Many amendments, change or equivalence, but fall within protection scope of the present invention.
