Based on above-mentioned hardware configuration, the more equipment wireless charging method embodiments of the present invention are proposed.
Referring to Fig. 2, Fig. 2 is the flow diagram of the more equipment wireless charging method first embodiments of the present invention.
In the first embodiment, more equipment wireless charging methods are applied to wireless charging device, the wireless charging
Equipment includes adapter and multiple emitters, more equipment wireless charging methods the following steps are included:
S10: current emitter obtains the input voltage of the adapter.
The terminal to charge is needed to set it should be understood that wireless charging device refers to be connected to without traditional charging power cord
Standby upper charging equipment, uses newest wireless charging technology, by using the alternating magnetic field generated between coil, transmission electricity
Energy.
The adapter is common adapter or quick charge (quick charge, QC) adapter, the power of adapter
It does not need to customize.
Each emitter corresponds to a receiving device, and more equipment wireless chargings refer to real using multiple emitters
Existing multiple equipment charging.
S20: when the input voltage is greater than predetermined voltage threshold, obtaining the first transmission power that receiving end needs, and
Receive the second transmission power of other emitters transmission.
It is understood that the receiving end can be mobile phone, laptop, smartwatch etc., the present embodiment is to this
It is without restriction.
The predetermined voltage threshold can be adjusted by software, and the corresponding predetermined voltage threshold of usual 5V input voltage is
The corresponding predetermined voltage threshold of 4.6V, 9V input voltage is 8.2V, and the corresponding predetermined voltage threshold of 12V input voltage is 11V.
It should be noted that current emitter is by receiving the reception power (received sent from receiving end
Power, RP) packet obtains the first transmission power, and it when multiple equipment charges simultaneously, RP may be generated is responsible for a task until it is completed and disturb, therefore can be with
Increase RP packet Anti-interference algorithm.For example, the objective emission power of current emitter is that (this threshold value may be according to user by 2.5W
Structure fine tuning) hereinafter, when the value of the first transmission power in the RP packet that receive is 0.6W bigger than objective emission power, then be judged as
It removes receiving end；In the case where there is bus, the RP packet that the RP packet and bus of current emitter detection receive completely to correspondence when
Then think that receiving end is removed, terminates power supply.
In the concrete realization, when adapter power is inadequate, i.e., when the input voltage is less than predetermined voltage threshold, by
The size of input voltage decision objective emission power.Specifically, input power is determined according to the input voltage, according to described defeated
Enter power and determine objective emission power, the receiving end is powered according to the objective emission power.
S30: input power is determined according to the input voltage.
It should be noted that, in each voltage input shelves, a default electricity is all arranged to guarantee that adapter does not go offline
Threshold value is pressed, when input voltage is equal to this predetermined voltage threshold, emitter is not further according to the control error of receiving end
(Control Error, CE) packet dynamic adjustment power, i.e., no longer reduce operating frequency or be not further added by full-bridge input voltage or
Increase duty ratio or phase difference, but maintains current power parameter state；If input voltage, which continues to reduce, is less than this threshold value
When, then full-bridge parameter (operating frequency, inverter bridge input voltage, duty ratio or phase difference) can be reversely adjusted, emitter is made
Transmission power reduces, to reduce the input power of emitter.When input voltage is higher than this predetermined voltage threshold, restore just
Normal algorithm passes through CE packet dynamic adjustment input power.Substantially, this function is that input voltage participates in emitter
PID (ratio, integral, differential control) algorithm (in process control, is carried out in the ratio (P) of deviation, integral (I) and differential (D)
The PID controller of control) in, predetermined voltage threshold parameter is introduced in common pid algorithm, controls the transmitting function of transmitting terminal
Rate.
S40: maximum transmission power is determined according to the input power and second transmission power.
It is understood that the maximum transmission power refers to can provide when the current emitter is receiving end power supply
Maximum transmission power.When multiple equipment charges simultaneously, the maximum transmission power of current emitter is input power and institute
State the difference of the second transmission power.
It should be noted that after the corresponding receiving end of other emitters is removed or charged state changes, described second
Transmission power can change, and therefore, the maximum transmission power is also dynamic.By taking receiving end is mobile phone as an example, if input
Power is 10W, other emitters are powered by mobile phone of the second transmission power of 5W, then the emission maximum function of current emitter
Rate is 5W.If mobile phone enters temperature control mechanism, the actual transmission power of other emitters is only 4W at this time, i.e., the second transmitting
Power is 4W, then the maximum transmission power of current emitter can be 6W, current emitter can be by the target of oneself
Emitter is adjusted to 6W, utilizes adapter power to greatest extent to reach.
S50: when the maximum transmission power is greater than first transmission power, using first transmission power as mesh
Mark transmission power.
In the concrete realization, the objective emission power is the output power of current emitter.When the emission maximum
When power is greater than first transmission power, illustrate that current emitter there are enough transmission powers for receiving end power supply, at this time
Receiving end can be charged the first transmission power needed as objective emission power by current emitter.
For example, the input power of adapter is 15W, the transmission power of other emitters is 10W, then current emitter
Maximum transmission power be 5W, and the first transmission power that the receiving end of current emitter needs is 3W, then using 3W as mesh
Transmission power is marked as receiving end power supply.
S60: the receiving end is powered according to the objective emission power.
It is understood that the current emitter is powered the receiving end according to objective emission power, with
Realize the wireless charging to receiving end.
Certainly, above situation is to have the case where bus, if only GPIO (General Purpose Input
Output, universal input/output) it communicates without bus, specific power information can not be obtained, then can set thresholding, than
The objective emission power for such as setting emitter is 8W the above are high power, and the following are low-power by 8W, when high power, setting
GPIO is height, and when low-power set GPIO to be low, and other emitters detect the GPIO of other side, adjust the objective emission of oneself
Power, while the GPIO of oneself is also set according to the objective emission power of oneself.Such as when detecting other side is high power,
The objective emission power for then limiting oneself is that common power does not limit the power of oneself then when detecting other side is low-power,
The high power of fast charge charging can be entered.
The present embodiment obtains the input voltage of adapter by current emitter；When input voltage is greater than predeterminated voltage threshold
When value, the first transmission power that receiving end needs is obtained, and receive the second transmission power of other emitters transmission；According to institute
It states input voltage and determines input power；Maximum transmission power is determined according to the input power and second transmission power；When
When the maximum transmission power is greater than first transmission power, using first transmission power as objective emission power；Root
The receiving end is powered according to the objective emission power, realizes the communication increased between emitter, dynamically distributes hair
Penetrate power, do not need custom fitting device, effectively increase the utilization rate of adapter, saved more equipment wireless charging devices at
This.
Further, as shown in figure 3, proposing that the more equipment wireless charging methods second of the present invention are implemented based on first embodiment
Example, in the present embodiment, step S50 is specifically included:
S501: when the maximum transmission power is greater than first transmission power, control error packet is obtained from receiving end.
It is understood that the value of CE packet can be 0, negative or positive.When practical control point is consistent with expected control point, CE
The value of packet is 0, and when needing reduces transmission power, the value of CE packet is negative, and when needing to increase transmission power, the value of CE packet is
Just.
It should be noted that may have CE when more equipment charge simultaneously and be responsible for a task until it is completed the case where disturbing, therefore can increase
CE packet Anti-interference algorithm.For example, the judgement of CE timer out parameter is changed to as long as having leader will preamble not timer
out；It continuously receives two identical CE packets and just carries out power regulation etc..
S502: objective emission power is adjusted to first transmission power according to the control error packet.
In order to precisely control objective emission power, pid algorithm is based on generally according to the CE packet and adjusts objective emission
Power makes the objective emission power reach first transmission power.
In the concrete realization, first transmission power is introduced in pid algorithm as variable, by adjusting operation frequency
Rate, inverter bridge input voltage, duty ratio or phase difference, make objective emission power reach the first transmission power.
The present embodiment is by obtaining CE packet from receiving end, according to control error packet adjusting objective emission power to described
First transmission power realizes the dynamic adjustment to objective emission power, effectively increases the utilization rate of adapter, saved more
The cost of equipment wireless charging device.
Further, as shown in figure 4, proposing that the more equipment wireless charging method thirds of the present invention are implemented based on first embodiment
Example, in the present embodiment, after step S40, the method also includes:
S50 ': when the maximum transmission power is less than first transmission power, the confession of judgement and other emitters
Electric priority.
It is to be appreciated that the power in order to rationally utilize adapter, it will usually have several algorithms, the equipment such as first filled is excellent
First the fast charge perhaps preferential fast charge of apple equipment or the preferential fast charge of Samsung equipment.Therefore, when the maximum transmission power is less than
When first transmission power, it can be judged according to the ID of power-on time or receiving end preferential with the power supply of other emitters
Grade.
When judging power supply priority according to power-on time, if the power-on time of current emitter is longer, illustrate than other
Emitter is first powered, then its power supply priority is higher, preferentially ensures current emitter power supply.
When judging power supply priority according to the ID of receiving end, if the current corresponding receiving end of emitter be apple equipment or
Samsung equipment, then the power supply priority of current emitter is higher, preferentially ensures current emitter power supply.
S60 ': when the power supply priority is lower, using the maximum transmission power as objective emission power.
It will be appreciated that being preferably that other emitters provide hair if the power supply priority of current emitter is lower
Power is penetrated, current emitter is only powered according to maximum transmission power.
It is then preferably that current emitter provides transmission power, at this point, current transmitting when the power supply priority is higher
Device is powered the receiving end using the first transmission power as objective emission power.
For example, the input power of adapter is 15W, the transmission power of other emitters is 10W, then current emitter
Maximum transmission power be 5W, and the first transmission power that the receiving end of current emitter needs is 6W, then needs to transmitting
The power supply priority of device is judged, if the receiving end of current emitter is apple equipment, then current emitter
Priority of powering is higher, then provides the objective emission power of 6W for current emitter, it is made preferentially to power, if current transmitting dress
The power supply priority set is lower, then only provides the objective emission power of 5W for current emitter, preferentially ensures other transmitting dresses
The power supply set.
The present embodiment is by the way that when the maximum transmission power is less than first transmission power, judgement is filled with other transmittings
The power supply priority set, using the maximum transmission power as objective emission power, works as institute when the power supply priority is lower
State power supply priority it is higher when, using the first transmission power as objective emission power, the receiving end is powered, is realized
Dynamic maximum limit utilizes adapter power, has saved the cost of more equipment wireless charging devices.
