It is fixed.Due to being covered by lampshade D or chassis B, transmitting terminal does not affect the appearance, and can be dust-proof to transmitting terminal well.
In the embodiment of the present invention, the quantity of transmitting terminal networking, depending on careat size, chargeable electronics is set
Standby quantity.It can be contacted between transmitting terminal by wired or wireless communication mode.
The wireless power method realized with reference to the wireless power supply system of Fig. 3 descriptions as above.As shown in figure 3, this is wireless
Method of supplying power to comprises the following steps：
Step S310, receiving terminal send position signal and charge request signal to transmitting terminal.
Assuming that the receiving terminal 2-1 in Fig. 1 needs to charge and sends charge request signal and the position letter of receiving terminal 2-1
Number.As an example, the position signal of charge request signal and receiving terminal 2-1 can be carried to be sent out in a piece of news
Send, but be not limited to this.
If receiving terminal 2-1 is only located at the power supply overlay area (such as receiving terminal 2-1 is in master bedroom) of transmitting terminal 1-2, only send out
End 1-2 is penetrated to receive the message from receiving terminal and carry out subsequent treatment (step S321- step S327).If receiving terminal 2-1
In the overlapping power supply coverage of transmitting terminal 1-2 and transmitting terminal 1-3, then transmitting terminal 1-2 and 1-3 receive receiving terminal
Message and carry out subsequent treatment (step S321- steps S327 and step S331- step S337).Hair is illustrated that in Fig. 3
Penetrate the situation that end 1-2 and 1-3 receives the charge request message of receiving terminal.
Step S321 and S331, transmitting terminal 1-2 and 1-3 each receive and identify the charging that wireless charging receiving terminal is sent please
Ask signal and position signal.
Step S323-S325 and step S333-S335, transmitting terminal 1-2 and 1-3 be each based on receive position signal with
And whether the distributed intelligence of transmitting terminal determines receiving terminal in the power supply coverage overlapped with adjacent transmission end in networking, and
Receiving terminal determines whether to be charged for receiving terminal by itself in the case of being in overlapping power supply coverage.
More specifically, for transmitting terminal 1-2, the positional information and thing that it can be based on receiving terminal 2-1 in step S323
The distributed intelligence of each transmitting terminal is covered to determine whether receiving terminal is in the power supply overlapped with adjacent transmission end in the networking first stored
Lid scope, if it is determined that receiving terminal is not at overlapping power supply coverage (coverage for only existing in transmitting terminal 1-2), then
Transmitting terminal 1-2 directly charges for wireless charging receiving terminal.
In the case where definite receiving terminal is in the power supply coverage that transmitting terminal 1-2 and 1-3 are overlapped, in step S325,
Transmitting terminal 1-2 can be using control module it is determined that being charged by whose (transmitting terminal 1-2 or 1-3).As an example, it is based on
The distributed intelligence of each transmitting terminal, transmitting terminal 1-2 can be calculated and connect in the positional information of receiving terminal 2-1 and the networking being previously stored
Distance of the receiving end away from transmitting terminal 1-2 and 1-3, by selecting shorter distance, transmitting terminal 1-2 can determine this by oneself still
Transmitting terminal 1-3 to charge to receiving terminal 2-1., can be based on predetermined preferential if distance of the receiving terminal away from two transmitting terminals is equal
Level or random selection transmitting terminal are as the transmitting terminal to charge to receiving terminal.As another example, it is in transmitting in definite receiving terminal
During the power supply coverage that end 1-2 and 1-3 is overlapped, transmitting terminal 1-2 can be by communication module or wired connection mode to transmitting terminal
Send the distance of oneself and receiving terminal 2-1.
When determining to be charged for wireless charging receiving terminal by itself, radio communication list is controlled in step S327 transmitting terminals 1-2
Microwave signal of the member radiation for charging, and the phase overlapped by communication module or wired mode to current power supply coverage
Adjacent wireless power supply sends standby instruction or the instruction of charging side.In this way, transmitting terminal 1-3 comes from adjacent transmission end 1- receiving
Charged state can be entered after 2 standby instruction or the instruction of charging side, or complete to fill in the case where currently there are charging tasks
Into charged state after electric task.
Similarly, transmitting terminal 1-3 also independently performs identical processing step (S333-S337).
Based on above-mentioned charging method, when receiving terminal is moved to bedroom, in the transmitting terminal coverage crossover range of two, parlor,
Bedroom transmitting terminal distance reception end position is near, and bedroom transmitting terminal sends standby signal to parlor transmitting terminal, and parlor transmitting terminal is excellent
First carry out and standby mode is just entered back into after charging tasks.
Not only networking is convenient for the wireless charging system and method for the present invention, but also can realize that wide coverage, intelligence are filled
Electricity and locating and tracking, substantially increase the efficiency of wireless charging.
In the embodiment of the present invention, transmitting terminal without charging task when, can be automatically into standby mode, when having charging tasks
Operating mode can be automatically waken up.Also, when receiving terminal is moved in two transmitting terminal coverage crossover ranges, apart from receiving terminal
The near transmitting terminal in position can send standby signal, another transmitting terminal can be current as the transmitting terminal of charging to another transmitting terminal
Direct standby in the case of without task, or standby mode is just entered back into after charging tasks preferentially having performed.
The smart home wireless charging transmitting terminal networking of the present invention can realize indoor wireless power supply all standing, mobile charging
Electronic equipment indoors Anywhere can be random carry out wireless charging.Preferably, transmitting terminal and ceiling light perfect adaptation, peace
Mounted in interior roof lamp position, it is unobstructed to realize microwave energy transfer path, improves wireless charging efficiency.Also, the present invention
In can be realized as big wireless power coverage without excessive microwave source power, also achieve energy saving purpose.
It should be appreciated that two or more modules in present invention device described here can be merged into a module,
Each module can also more be subdivided into multiple submodule, not affect the realization of the present invention.
The each several part of the present invention can be realized with hardware, software, firmware or combinations thereof.In the above embodiment
In, software or firmware that multiple steps or method can be performed in memory and by suitable instruction execution system with storage come
Realize.If for example, being realized with hardware, with another embodiment, the known following technology in this area can be used
Any one of or their combination realize：With the logic gates for realizing logic function to data-signal from
