Cs4 ’處理器24c可俄測得知電壓vdl -VdM及系統電壓vs 之位準。舉例來說’當電壓Vdi的位準實質上大於參考電 壓Vf(=Vrl)時，處理器24c提供選擇訊號Cs5控制多工器 24g將對應之能量接收模組24ai中儲存之能量prei，提供 ❿至系統電能電路24e ’並將其暫存在系統電能電路24e中。 如此，透過處理器24與偵測電路24d之操作，系統電能 電路24e可儲存各能量接收模組24al-24aM所接收之能 量。 當系統電壓Vs之位準實質上大於參考電壓Vf(=Vf2) 時’處理器24c提供控制訊號Cs6致能電荷泵24f，使其 根據系統電能電路24e中之電能來產生系統電能訊號Ed， 以對位於接收端裝置24端之電子裝置（未繪示）中之電池 ©(未繪示）進行充電。如此’本實施例之接收端裝置24可 無線地接收發送端裝置22提供之能量，並據以對位於接 收端裝置24端之電子裝置進行供電。 處理器24c更透過偵測控制訊號Cs4之位準變化來找 出能量接收模組24al-24aM中能量接收效率較佳之能量接 收模組。處理器24c更透過射頻訊號發送電路24b將前述 能量接收效率較佳之能量接收模組的資訊提供至發送端 裝置22,以驅動其透過與能量接收效率較佳之能量接收模 組對應之能量發送模組進行能量傳遞。 在一個例子中’處理器24c定義電壓訊號vdl-VdM之 位準實質上大於參考電壓Vf〇參考電壓Vr2)之事件為特 定事件Evtl-EvtM。在處理器24c所執行之各次輪詢操作 中，處理器24c更用以回應於觸發事件Evtl_EvtM來分別 對计數值Val-VaM進行計數操作。由於各計數值yai_vaM 之操做為實質上相同，接下來以處理器24c對計數值Vaj· 之計數操作為例作說明，j為小於或等於Μ之自然數。計 ❹數值Va]•之初始數值為〇，處理器24c係回應於觸發事件 Evtj將計數值Vaj遞增丨。相似地操作亦被執行於計數值 Val-VaM中其他之計數值，如此，處理器2切在κ次 操作後計算得到計數值Val-VaM。 處理器24c更選擇計數值Val-VaM中具有最大數值之 一筆或一筆以上之計數值對應之能量接收模組為能量接 收效率較佳之能量接收模組，並在特定操作期間中，經由 此一個或一個以上之能量接收效率較佳之能量接收模組 Φ接收能量。處理器24c對應地產生射頻訊號以來記錄能 量接收效率較佳之能量接收模組之資訊，並將射頻訊號St 經由射頻訊號發送電路24b輸出至射頻訊號接收電路22卜 射頻訊號接收電路24b包括射頻天線24bl及射頻訊 號處理電路24b2。射頻訊號處理電路24b2用以對射頻訊 號St進行諸如編解碼及解調變操作後經由射頻天線“Μ 輸出。如此，發送端裝置22可回應於接收端装置24提供 之射頻訊號St選擇發送端裝置22中對應之能量發送模组 15 201010235 來進行能量傳輸。 在本實施例中，雖僅以處理器24c透過輪詢操作來對 偵測電路24d中之電壓選擇電路24d2及24dl進行控制的 情形為例作說明，然，本實施例之處理器24c並不侷限於 此。在另一個例子中，處理器24c更例如具有使用者介面 模式，可回應於使用者提供之指令來進行前述電壓選擇電 路24d2及24dl之控制。在此例子中，處理器24c例如是 8051微處理器。 ❿ 在本實施例中，雖僅以能量接收模組24al-24aM接收 之能量Pre卜PreM經由多工器24g之多工操作提供至系統 電能電路24e的情形為例作說明，然，能量接收模組 24a卜24aM接收之能量prei-preM並不侷限於經由前述路 徑提供至系統電能電路24e。 在一個例子中，接收端裝置24更具有能量電路p，其 受控於處理器24c，在能量接收模組24w_24aM接收之能 量非常微弱時統一蒐集所有能量接收模組24al-24aM接收 ❿之能量’並據以對電子裝置進行供電。舉例來說，處理器 24c係以於執行K次輪詢操作後得到之計數值VM_VaM小 於或等於低臨界值時判斷能量接收模組24al_24aM接收之 能量非常微弱’並致能能量電路p來蒐集所有能量接收模 組24al-24aM接收之能量。 請參照第6圖，其繪示乃第3圖之接收端裝置24的 傳輸路徑的示意圖。能量電路P包括加總電路Pa及整流 電路Pc。加總電路Pa包括Μ個開關電路swi-SWM，其分 16 201010235 別设置於能量接收模組24al-24aM中。各開關電路SW卜SWM 係受控於處理器24c提供之控制訊號Cs7來進行切換。在 正常操作下，處理器24c係提供第一位準之控制訊號Cs7。 此時’開關SW1-SWM係導通對應之共振器RS與整流電路 Rec間之路徑，使對應之能量接收模組24al_24aM執行前 述之能量接收操作。 在處理器24c判斷能量接收模組24a卜24aM接收之能 量非常微弱時，處理器24c係提供第二位準之控制訊號 ❹Cs7。此時，開關SW1_SWM係將所有共振器RS耦接至整流 電路Pc。如此，透過加總電路pa之操作可對能量接收模 組24a卜24aM接收到之能量pre卜preM進行加總。而能量The Cs4' processor 24c can detect the level of the voltage vdl - VdM and the system voltage vs. For example, when the level of the voltage Vdi is substantially greater than the reference voltage Vf (=Vrl), the processor 24c provides the selection signal Cs5 to control the multiplexer 24g to provide the energy prei stored in the corresponding energy receiving module 24ai. The system power circuit 24e' is temporarily stored in the system power circuit 24e. Thus, through the operation of the processor 24 and the detecting circuit 24d, the system power circuit 24e can store the energy received by each of the energy receiving modules 24al-24aM. When the level of the system voltage Vs is substantially greater than the reference voltage Vf (= Vf2), the processor 24c provides the control signal Cs6 to enable the charge pump 24f to generate the system power signal Ed according to the power in the system power circuit 24e. The battery © (not shown) in the electronic device (not shown) at the end of the receiving device 24 is charged. Thus, the receiving device 24 of the present embodiment can wirelessly receive the energy provided by the transmitting device 22, and thereby supply power to the electronic device at the terminal end of the receiving device 24. The processor 24c further detects the level change of the control signal Cs4 to find an energy receiving module with better energy receiving efficiency in the energy receiving module 24al-24aM. The processor 24c further provides the information of the energy receiving module with better energy receiving efficiency to the transmitting device 22 through the RF signal transmitting circuit 24b to drive the energy transmitting module corresponding to the energy receiving module with better energy receiving efficiency. Conduct energy transfer. In one example, the event that processor 24c defines the level of voltage signal vdl-VdM to be substantially greater than reference voltage Vf 〇 reference voltage Vr2 is a particular event Evtl-EvtM. In each polling operation performed by the processor 24c, the processor 24c is further configured to perform a counting operation on the count value Val-VaM in response to the trigger event Evtl_EvtM, respectively. Since the operation of each count value yai_vaM is substantially the same, the counting operation of the count value Vaj· by the processor 24c will be described as an example, and j is a natural number less than or equal to Μ. The initial value of the value Va] is 〇, and the processor 24c increments the count value Vaj in response to the trigger event Evtj. The similar operation is also performed on the other count values in the count value Val-VaM, so that the processor 2 calculates the count value Val-VaM after the κ operation. The processor 24c further selects the energy receiving module having the highest value of one or more than one of the count values Val-VaM as the energy receiving module with better energy receiving efficiency, and during the specific operation period, via the one or More than one energy receiving module Φ with better energy receiving efficiency receives energy. The processor 24c correspondingly generates the information of the energy receiving module with better energy receiving efficiency since the RF signal is generated, and outputs the RF signal St to the RF signal receiving circuit 22 via the RF signal transmitting circuit 24b. The RF signal receiving circuit 24b includes the RF antenna 24bl. And RF signal processing circuit 24b2. The RF signal processing circuit 24b2 is configured to perform an output operation such as a codec and a demodulation operation on the RF signal St via the RF antenna. Thus, the transmitting device 22 can select the transmitting device in response to the RF signal St provided by the receiving device 24. Energy transfer is performed by the corresponding energy transmitting module 15 201010235 in Fig. 22. In the present embodiment, the case where the voltage selection circuits 24d2 and 24d in the detecting circuit 24d are controlled by the processor 24c only through the polling operation is For example, the processor 24c of the embodiment is not limited thereto. In another example, the processor 24c further has a user interface mode, and the voltage selection circuit can be performed in response to an instruction provided by the user. Control of 24d2 and 24dl. In this example, the processor 24c is, for example, an 8051 microprocessor. ❿ In this embodiment, only the energy received by the energy receiving modules 24al-24aM is pre-PreM via the multiplexer 24g. The case where the multiplex operation is provided to the system power circuit 24e is exemplified. However, the energy prei-preM received by the energy receiving module 24a 24aM is not limited to The path is provided to system power circuit 24e. In one example, receiver device 24 further has an energy circuit p that is controlled by processor 24c to collectively collect all energy receiving modes when the energy received by energy receiving module 24w_24aM is very weak. The group 24al-24aM receives the energy of the device and supplies power to the electronic device. For example, the processor 24c determines the energy reception when the count value VM_VaM obtained after performing the K-th polling operation is less than or equal to the low threshold value. The energy received by the module 24al_24aM is very weak' and the energy circuit p is enabled to collect the energy received by all the energy receiving modules 24al-24aM. Please refer to FIG. 6 , which shows the transmission path of the receiving device 24 of FIG. 3 . The energy circuit P includes a summing circuit Pa and a rectifying circuit Pc. The summing circuit Pa includes a switching circuit swi-SWM, which is disposed in the energy receiving module 24al-24aM by 16 201010235. The SWM is controlled by the control signal Cs7 provided by the processor 24c for switching. Under normal operation, the processor 24c provides the first level of the control signal Cs7. The SW1-SWM system turns on the path between the corresponding resonator RS and the rectifying circuit Rec, so that the corresponding energy receiving module 24al_24aM performs the aforementioned energy receiving operation. The processor 24c determines that the energy received by the energy receiving module 24a 24aM is very When the faint is weak, the processor 24c provides the second level of the control signal ❹Cs7. At this time, the switch SW1_SWM couples all the resonators RS to the rectifying circuit Pc. Thus, the operation of the summing circuit pa can be used for the energy receiving module. The energy preb preM received by 24abu 24aM is summed. And energy

In this embodiment, the processor 22c only selects a part or all of the energy transmitting modules 22al-22aN to transmit the energy according to the RF signal St. However, the processor 22c is not limited. Do this. In one example, processor 22c only enables one of the energy transmitting modules 22al-22aN at a time. Thus, the RF signal st responded by the receiving device 24 indicates whether the receiving device 24 can effectively receive energy via the energy receiving module corresponding to the energy transmitting module. When the RF signal St indicates that the receiving device 24 is unable to efficiently receive energy, the processor 22c drives another energy transmitting module of the energy transmitting modules 22al-22aN for energy transfer. 201010235 5 Referring to FIG. 7 , the wireless energy transmission method of the embodiment of the present invention is 4=, I, in the example, the wireless energy transmission method includes the following step.

For example, the second energy transmitting module is powered by, and j' is controlled by the processor 22. The transmit energy add-on, f ^ as in step (4) processor 22c, after delaying the specific transmission time, step (8) to receive the next RF signal st, and according to the judgment of step (c). Among them, the processor 22 is used. When it is judged in the step (6) that the device 22 can effectively output the monthly b amount via the corresponding wireless energy transmission path, the step (e) is performed. The "_ line" method of transmitting the quantity further includes, for example, the step 步骤 before the step (a), and the processor 22C determines whether the source device 22 operates on the automatic transmission line to perform energy transmission via the automatic transmission mode; if yes, the system performs: If no, step (g) is executed, and the processor 22c responds to the operation to set the transmitting terminal 22 to perform the corresponding sending operation of the 201010235. Referring to Figures 8A, 8B and 8C, A flowchart of a wireless energy receiving method according to an embodiment of the present invention is shown. In one example, the wireless energy receiving method includes the following steps. First, as step (a), the processor 24c utilizes one energy receiving module 24al-24aM. The pen energy Prel-PreM′ is received via the two wireless energy transmission paths respectively, and the corresponding energy is stored in the corresponding energy receiving modules 24al-24aM respectively. Then, as in step (b), the processor 24c is configured according to the The energy stored in the energy receiving module © 24al_24aM determines whether the energy receiving modules 24al-24aM have energy receiving modules with better energy receiving efficiency; if yes, step (c) is performed. During the operation period, the receiving device 24 receives the energy through the energy receiving module of the preferred energy receiving efficiency. Then, in step (d), the processor 24c provides the RF signal to the transmitting device via the RF signal transmitting circuit 24b. 22. In one example, the transmitting device 22 determines, based on the RF signal St, whether the receiving device 24 can effectively receive the energy receiving mode via the preferred energy receiving efficiency, in an example, as shown in FIG. The energy transmitting method, the energy receiving method shown in Fig. 8A further includes steps (4) and l. In the example, the step (_ includes step (10), '° down, and the step (bl)_(bll) Further, in step (8), the first step (bl) is performed, and the processor 24 determines, according to the control (10) CS4, an energy receiving module that meets the specific conditions of the first root of 201010235. It is said that the first specific condition is that the level of (4) provided by the energy receiving module is substantially greater than the condition of the reference voltage Vf (-reference voltage Vf2). For example, the processor 24c determines the receiving module 24a, for example, in order. Whether the 24aM satisfies the first-specific condition. Next, in step (b2), the processor 24c increments the count value corresponding to the energy receiving module that satisfies the first special condition, and provides the control signal Cs5 to control the multiplexer 24g. The energy stored in the corresponding energy receiving module 24a 24a is stored in the system power circuit 24e. ❹ Then, as in step (b3), the processor 24c determines whether the step 〇3 2 has been performed, which is a natural number greater than 1. If not, the step (bl) is repeatedly executed, and if so, the step (b6) is executed, and the processor 24c determines whether the river count value Val VaM does not satisfy a special condition. For example, this specific condition is a condition that all of the count values va, VaM, are at or equal to a low threshold. When each of the counts 3 does not satisfy the specific condition, step (b7) is executed. 'The processor 24c performs the energy receiving module with the highest count value corresponding to one or more of the count values VaHaM.

Thus, in step (c), the energy receiving operation can be performed via the one or more energy receiving modules during the next specific operation period. As shown in FIG. 8D, after the step (4), the energy receiving method of the embodiment further performs the step (g). The processor 24c determines the better energy with the one or more after delaying the specific operation period. Whether the energy stored in the energy receiving module of the receiving efficiency is greater than a critical value; if so, the energy receiving module indicating the one or more preferred energy receiving efficiencies, 20 201010235 has an ideal receiving efficiency, and is repeated at this time Performing step (b7) to continuously receive the month d, or right, via the energy receiving module of the one or more preferred energy receiving efficiencies, indicating energy reception of the one or more preferred energy receiving efficiencies The module has poor reception efficiency, and step (a) is performed at this time. In step (b7), if the processor 24c determines that the count value does not satisfy the specific condition, the step (10) is executed, and the processor W provides the control unit ^^S? The total circuit Pa' is summed with the energy received by the M energy=(four) groups 24al-24aM, and is transformed by the voltage transformer bb: the rectifier circuit Pc generates the system power signal rib, and then the step 24 is performed after delaying the specific operation period. The step (4) is repeatedly performed to perform the energy receiving method of the present embodiment. In the example, the 'energy receiving method is between steps (10) and (10). The step (10)' processor 24c determines whether the system power circuit W is eating the first characteristic condition. For example, the second specific condition is that the system power is not satisfied with the second step 11 in step (b4). If the system power circuit 24e is judged/the first specific condition is satisfied, the step (b3) is performed. When the processor 24C determines that the system power circuit % satisfies the second specific power 23, the processor W provides the control signal Cs6 to drive the Si::charge pump to generate the drive er according to the system voltage VS. After the step (b5), the step (b3) is performed. The example of the step (10) and ((8) includes, for example, a step), and the processor 24c triggers an alert event through the user interface. 21 201010235 The energy transfer system of the present embodiment and its method of energy transmission and energy reception apply a number of wireless energy transfer modules to wirelessly perform energy transfer.
