Description
本創作係指一種用於無線充電系統之供電裝置及受電裝置及其充電控制器，尤指一種可執行選擇性無線充電方法之供電裝置及受電裝置及其充電控制器。 The present invention relates to a power supply device and a power receiving device for a wireless charging system and a charging controller thereof, and more particularly to a power supply device and a power receiving device and a charging controller thereof that can perform the selective wireless charging method.
隨著可攜式電子裝置，如行動裝置、智慧型手機及平板電腦的普及，充電裝置的需求不斷增加，尤其對需要提供充電的公共場所更是明顯。此外，由於多數人都希望能夠盡可能減少攜帶連接線，無線充電技術於是應運而生。當無線充電的技術被應用在電子裝置，乃是將具有一電力接收器的電子裝置放置於無線充電裝置(例如包含有電力發射器之一電力基站(Power Base Station，PBS))上，並透過無線充電裝置進行充電。因此，目前的趨勢旨在提供公共場所無線充電的服務與功能，如咖啡館、商店、火車站、機場、餐廳等，讓人們可以很容易地找到一個無線供電的場所來提供電子裝置充電的服務與需求。 With the popularity of portable electronic devices, such as mobile devices, smart phones and tablets, the demand for charging devices is increasing, especially in public places where charging is required. In addition, since most people want to be able to reduce the carrying of the cable as much as possible, wireless charging technology came into being. When the wireless charging technology is applied to an electronic device, an electronic device having a power receiver is placed on a wireless charging device (for example, a power base station (PBS) including a power transmitter), and is transmitted through The wireless charging device performs charging. Therefore, the current trend is to provide services and functions for wireless charging in public places, such as cafes, shops, train stations, airports, restaurants, etc., so that people can easily find a wireless power supply to provide electronic device charging services. With demand.
在無線充電之技術領域中，無線電力聯盟(Alliance for Wireless Power，A4WP)、無線充電聯盟(Wireless Power Consortium)及電力事業聯盟(Power Matters Alliance，PMA)等全球性組織已為無線充電定義了各種規格，其定義無線電力可在不使用實體連結的情況下，從一無線充電發射器（Wireless Charger Transmitter，WCT）傳送至位於一定距離內的一無線充電接收器（Wireless Charger Receiver，WCR）。目前的無線充電機制是任何充電裝置皆可配對且是以『先來先贏』的方式進行，也就是說，當無線充電接收器靠近無線充電發射器且此無線充電發射器仍具有可使用的（即未被其它裝置佔用的）電力傳送端時，即可進行充電。In the field of wireless charging technology, global organizations such as Alliance for Wireless Power (A4WP), Wireless Power Consortium, and Power Matters Alliance (PMA) have defined various types of wireless charging. The specification, which defines wireless power, can be transmitted from a Wireless Charger Transmitter (WCT) to a Wireless Charger Receiver (WCR) located within a certain distance without the use of physical connections. The current wireless charging mechanism is that any charging device can be paired and is performed in a "first come, first win" manner, that is, when the wireless charging receiver is close to the wireless charging transmitter and the wireless charging transmitter is still usable. When the power transmitting end (ie, not occupied by other devices) is used, charging can be performed.
然而，現有的規格乃針對電源充電本身，而針對其它應用卻沒有任何考量。例如，提供無線充電的場所並沒有辦法對使用無線充電的消費者進行收費，也無法選擇對特定的具有充電權限的裝置進行充電。有鑑於此，實有必要在現有的無線充電技術與規格上增加選擇性充電的機制，以滿足提供無線充電服務之廠商的業務需求。However, the existing specifications are for the power supply itself, but for other applications without any consideration. For example, there is no way to charge consumers who use wireless charging, and there is no way to charge a particular device with charging authority. In view of this, it is necessary to add a selective charging mechanism to existing wireless charging technologies and specifications to meet the business needs of vendors providing wireless charging services.
因此，本創作之主要目的即在於提供一種用於無線充電系統之供電裝置及受電裝置及其充電控制器，其可執行選擇性無線充電，以藉由充電權限的判斷來實現各種關於無線充電的應用及服務。Therefore, the main purpose of the present invention is to provide a power supply device and a power receiving device for a wireless charging system and a charging controller thereof, which can perform selective wireless charging to realize various wireless charging by determining the charging authority.

根據流程40，在無線充電系統10中，供電裝置100會持續發送廣播訊號，當受電裝置102所對應之一電子裝置需充電時，受電裝置102會開始搜尋供電裝置100所發送的廣播訊號（步驟402）。廣播訊號可包含一種資料型態，受電裝置102可根據資料型態來判斷供電裝置100的存在。詳細來說，資料型態可能是任何加密或非加密的封包或資料，可由受電裝置102進行識別。當受電裝置102接收到可識別之資料型態時，即可得知附近存在供電裝置100，受電裝置102並判斷供電裝置100可與之配對並提供電力。受電裝置102可顯示附近存在的供電裝置100資訊，使用者即可移動受電裝置102使其靠近供電裝置100並進入供電裝置100之可充電範圍內。接著，受電裝置102可根據廣播訊號之強度來判斷供電裝置100與受電裝置102之間的距離（步驟404）。在一實施例中，廣播訊號可包含一無線訊號強度指示（Radio Signal Strength Indication，RSSI），受電裝置102可根據無線訊號強度指示的數值來判斷訊號強度，進而判斷供電裝置100與受電裝置102之間的距離。一般來說，訊號強度愈強代表兩者之間的距離愈短。進一步地，受電裝置102可設定一臨界值（例如設定供電裝置100之可充電範圍為臨界值），並於判斷出供電裝置100與受電裝置102之間的距離小於臨界值時，主動與供電裝置100建立連線，並向供電裝置100告知受電裝置102欲進行充電（步驟406）。舉例來說，受電裝置102可向供電裝置100發出一連線請求，當供電裝置100接受連線請求之後，兩者即可相互連線並進行通訊。上述連線可透過供電裝置100中的通訊單元212以及受電裝置102中的通訊單元312來實現，其可透過無線通訊技術進行連線，連線方式可以是任何規格的通訊協定，如藍牙（Bluetooth）、藍牙低功耗（Bluetooth Low Energy，BLE）、無線相容性認證（Wireless Fidelity，Wi-Fi）或射頻（Radio Frequency，RF）訊號等，但不限於此。According to the process 40, in the wireless charging system 10, the power supply device 100 continuously transmits the broadcast signal. When one of the electronic devices corresponding to the power receiving device 102 needs to be charged, the power receiving device 102 starts to search for the broadcast signal sent by the power supply device 100 (step 402). The broadcast signal may include a data type, and the power receiving device 102 may determine the presence of the power supply device 100 according to the data type. In detail, the data type may be any encrypted or non-encrypted packet or material that can be identified by the powered device 102. When the power receiving device 102 receives the identifiable data type, it can be known that the power supply device 100 is present nearby, and the power receiving device 102 determines that the power supply device 100 can be paired with it and provide power. The power receiving device 102 can display the information of the power supply device 100 existing nearby, and the user can move the power receiving device 102 to be close to the power supply device 100 and enter the chargeable range of the power supply device 100. Next, the power receiving device 102 can determine the distance between the power supply device 100 and the power receiving device 102 based on the strength of the broadcast signal (step 404). In an embodiment, the broadcast signal may include a Radio Signal Strength Indication (RSSI), and the power receiving device 102 may determine the signal strength according to the value indicated by the wireless signal strength, thereby determining the power supply device 100 and the power receiving device 102. The distance between them. In general, the stronger the signal strength, the shorter the distance between the two. Further, the power receiving device 102 can set a threshold (for example, setting the chargeable range of the power supply device 100 to a critical value), and when determining that the distance between the power supply device 100 and the power receiving device 102 is less than a critical value, the active power supply device 100 establishes a connection and informs the power supply device 100 that the power receiving device 102 is to be charged (step 406). For example, the power receiving device 102 can send a connection request to the power supply device 100. After the power supply device 100 accepts the connection request, the two can be connected to each other and communicate. The connection may be implemented by the communication unit 212 in the power supply device 100 and the communication unit 312 in the power receiving device 102. The connection may be through a wireless communication technology, and the connection manner may be any specification communication protocol, such as Bluetooth (Bluetooth). ), Bluetooth Low Energy (BLE), Wireless Fidelity (Wi-Fi) or Radio Frequency (RF) signals, but not limited to.
接著，透過供電裝置100與受電裝置102之間的連線及相互溝通，可進一步判斷兩者是否相容。相容代表供電裝置100與受電裝置102符合相同的無線充電規格，亦即，供電裝置100能夠對受電裝置102進行充電。接著，供電裝置100可判斷受電裝置102是否具有一充電權限，並據以決定是否對受電裝置102進行充電。供電裝置100可根據溝通過程中交換的資訊來判斷受電裝置102是否具有充電權限。當受電裝置102被判斷為具有充電權限時，供電裝置100即可開始供電，使得受電裝置102可從供電裝置100接收電力（步驟408）。相反地，當供電裝置100判斷受電裝置102不具有充電權限時，則不對受電裝置102進行充電。Then, through the connection and communication between the power supply device 100 and the power receiving device 102, it can be further determined whether the two are compatible. The compatible power supply device 100 and the power receiving device 102 conform to the same wireless charging specification, that is, the power supply device 100 can charge the power receiving device 102. Next, the power supply device 100 can determine whether the power receiving device 102 has a charging authority and determine whether to charge the power receiving device 102 accordingly. The power supply device 100 can determine whether the power receiving device 102 has charging authority based on information exchanged during the communication process. When the power receiving apparatus 102 is judged to have the charging authority, the power supply apparatus 100 can start power supply, so that the power receiving apparatus 102 can receive power from the power supply apparatus 100 (step 408). Conversely, when the power supply device 100 determines that the power receiving device 102 does not have the charging authority, the power receiving device 102 is not charged.
根據上述關於流程40之說明搭配第2圖之供電裝置100可知，供電裝置100中的處理裝置214可判斷受電裝置102是否具充電權限，來決定是否開啟開關218。也就是說，供電裝置100可藉由控制開關218的啟閉來實現選擇性充電。當處理裝置214判斷受電裝置102具有充電權限時，可開啟開關218，使得電力可從電源供應端202傳送至無線充電模組200再發送至受電裝置102。當處理裝置214判斷受電裝置102不具有充電權限時，則關閉開關218，此時無線充電模組200無法發送無線電力。需注意的是，第2圖之供電裝置100僅為本創作眾多實施方式當中的一種，在另一實施例中，亦可將開關218內建於無線充電模組200，抑或由處理裝置214直接控制無線充電模組200以決定無線充電模組200是否發送電力，而不限於此。According to the description of the flow 40 described above, in conjunction with the power supply device 100 of FIG. 2, the processing device 214 of the power supply device 100 can determine whether or not the power receiving device 102 has charging authority to determine whether to open the switch 218. That is to say, the power supply device 100 can achieve selective charging by controlling the opening and closing of the switch 218. When the processing device 214 determines that the power receiving device 102 has charging authority, the switch 218 can be turned on so that power can be transmitted from the power supply terminal 202 to the wireless charging module 200 and then transmitted to the power receiving device 102. When the processing device 214 determines that the power receiving device 102 does not have the charging authority, the switch 218 is turned off, and the wireless charging module 200 cannot transmit the wireless power. It should be noted that the power supply device 100 of FIG. 2 is only one of many implementations of the present invention. In another embodiment, the switch 218 can be built in the wireless charging module 200 or directly by the processing device 214. The wireless charging module 200 is controlled to determine whether the wireless charging module 200 transmits power, without being limited thereto.
上述關於流程40中供電裝置100之運作方式及相關說明可歸納為一流程50，如第5圖所示。流程50可用於一無線充電系統之一供電裝置，如第1圖所示之供電裝置100，用來執行選擇性無線充電方法。流程50可實現於供電裝置100中的充電控制器210，其包含以下步驟：The operation mode and related description of the power supply device 100 in the above process 40 can be summarized as a process 50, as shown in FIG. The process 50 can be used in a power supply device of a wireless charging system, such as the power supply device 100 shown in FIG. 1, for performing a selective wireless charging method. The process 50 can be implemented in the charging controller 210 in the power supply device 100, which includes the following steps:
步驟500： 開始。Step 500: Start.
步驟502： 持續發送一廣播訊號。Step 502: Continuously send a broadcast signal.
步驟504： 接收來自於無線充電系統10之受電裝置102之一連線請求，以與受電裝置102建立連線。Step 504: Receive a connection request from the power receiving device 102 of the wireless charging system 10 to establish a connection with the power receiving device 102.
步驟506： 判斷受電裝置102是否具有一充電權限，並據以決定是否對受電裝置102進行充電。Step 506: Determine whether the power receiving device 102 has a charging authority, and accordingly determine whether to charge the power receiving device 102.
步驟508： 結束。Step 508: End.
關於流程50之詳細運作方式已在上述相關於流程40的段落中進行說明，於此不贅述。The detailed operation of the process 50 is described in the above paragraphs relating to the process 40 and will not be described here.
進一步地，在充電過程中，供電裝置100可持續判斷受電裝置102與供電裝置100之間的距離。當判斷兩者之間的距離大於臨界值時，供電裝置100會停止供應電力至受電裝置102。如上所述，此臨界值亦可設定為供電裝置100的可充電範圍。若受電裝置102持續位於供電裝置100的可充電範圍內時，供電裝置100可持續對受電裝置102進行充電。若受電裝置102遠離供電裝置100而超出其可充電範圍時，供電裝置100則停止充電，並開始發送廣播訊號以通知其它受電裝置進行連線。透過上述方式，若受電裝置102為行動裝置時（如手機或平板電腦），使用者在判斷行動裝置之電量足夠時只需要移開行動裝置即可停止充電。在一實施例中，供電裝置100還可在充電結束時，記錄相關於受電裝置102之充電資訊，此充電資訊可用來計費或作為消費行為的記錄。Further, during the charging process, the power supply device 100 can continuously determine the distance between the power receiving device 102 and the power supply device 100. When it is judged that the distance between the two is greater than the critical value, the power supply device 100 stops supplying power to the power receiving device 102. As described above, this threshold value can also be set to the chargeable range of the power supply device 100. If the power receiving device 102 continues to be within the chargeable range of the power supply device 100, the power supply device 100 can continue to charge the power receiving device 102. If the power receiving device 102 is away from the power supply device 100 and exceeds its chargeable range, the power supply device 100 stops charging and starts transmitting a broadcast signal to notify other power receiving devices to connect. In the above manner, if the power receiving device 102 is a mobile device (such as a mobile phone or a tablet computer), the user only needs to remove the mobile device to stop charging when determining that the mobile device has sufficient power. In an embodiment, the power supply device 100 may also record charging information related to the power receiving device 102 at the end of charging, and the charging information may be used for billing or as a record of consumption behavior.
值得注意的是，上述充電權限可以是受電裝置102之優先權、受電裝置102取得之一授權碼、可用於充電之點數、或可用於充電之儲值金額或時間等。舉例來說，受電裝置102可在與供電裝置100建立連線時，傳送一授權碼至供電裝置100，此授權碼可能是以預付卡的形式，由受電裝置102之使用者藉由購買、贈送或其它方式而取得。此外，授權碼也可記載可用於充電之點數、儲值金額或時間等資訊，供電裝置100可取得這些資訊並據以對受電裝置102進行充電，如特定充電時間或電流量等。當受電裝置102已完成授權碼所對應的充電時間或流量時，供電裝置100即可停止充電，同時授權碼失效，使用者需再取得另一授權碼才可繼續充電。或者，受電裝置102亦可在與供電裝置100建立連線時，傳送一身分識別，身分識別為對應於特定受電裝置之身分，與上述授權碼不同。舉例來說，受電裝置102之使用者可註冊用於供電裝置100之使用者帳戶，其包含相對應的身分識別和密碼，當受電裝置102欲進行充電時，可在連線過程中傳送身分識別和密碼至供電裝置100，若供電裝置100判斷為正確的身分識別和密碼，即可對受電裝置102進行充電。供電裝置100再根據使用者帳戶包含的資訊（如信用卡資訊）對使用者收費，或由使用者預先儲值。It should be noted that the above charging authority may be the priority of the power receiving device 102, the authorization code obtained by the power receiving device 102, the number of points available for charging, or the stored value amount or time for charging. For example, the power receiving device 102 can transmit an authorization code to the power supply device 100 when establishing a connection with the power supply device 100. The authorization code may be in the form of a prepaid card, which is purchased and presented by the user of the power receiving device 102. Or obtained by other means. In addition, the authorization code may also record information such as the number of points that can be used for charging, the amount of stored value, or the time. The power supply device 100 can obtain the information and charge the power receiving device 102, such as a specific charging time or current amount. When the power receiving device 102 has completed the charging time or flow rate corresponding to the authorization code, the power supply device 100 can stop charging, and the authorization code is invalid, and the user needs to obtain another authorization code to continue charging. Alternatively, the power receiving device 102 may transmit an identity identification when the connection with the power supply device 100 is established, and the identity is identified as being corresponding to the specific power receiving device, which is different from the authorization code. For example, a user of the power receiving device 102 can register a user account for the power supply device 100, which includes a corresponding identity identification and password. When the power receiving device 102 wants to perform charging, the identity identification can be transmitted during the connection process. And the password to the power supply device 100, if the power supply device 100 determines that the correct identity and password are correct, the power receiving device 102 can be charged. The power supply device 100 charges the user according to the information (such as credit card information) contained in the user account, or pre-stores the value by the user.
除此之外，受電裝置102傳送至供電裝置100之資訊可包含充電之優先權。舉例來說，不同使用者帳戶可能依其繳費高低或使用頻率多寡而有不同的優先權，授權碼亦可記載關於優先權的資訊。在一實施例中，若供電裝置100正在對受電裝置102進行充電時接收到受電裝置104之連線請求，供電裝置100可比較受電裝置102及104之間的優先權，若受電裝置102之優先權高於受電裝置104時，供電裝置100不會接受受電裝置104之連線請求並繼續對受電裝置102進行充電。在另一實施例中，若供電裝置100正在對受電裝置102進行充電時接收到受電裝置106之連線請求，且受電裝置106之優先權高於受電裝置102，在此情形下，若供電裝置100沒有多餘的電源輸出端點提供予受電裝置106時，供電裝置100會停止對受電裝置102進行充電，改為接受受電裝置106的連線請求並開始對受電裝置106進行充電。在又一實施例中，當受電裝置102及104同時傳送連線請求至供電裝置100時，供電裝置100可選擇優先權較高的一受電裝置來連線並進行充電。需注意的是，上述優先權高低可能來自於各種情況，例如當一受電裝置之電量較低時，可具有較高的優先權；抑或一受電裝置的使用者可花費較多金額來購買優先進行充電的權力，但不限於此。除此之外，供電裝置100之擁有者（例如商店）亦可指定供電裝置100對特定受電裝置進行充電。需注意的是，充電權限可記載任何相關於充電的資訊，使得供電裝置可據以判斷是否對受電裝置進行充電，此資訊並不限於上述授權碼、身分識別或優先權等。In addition, the information transmitted by the power receiving device 102 to the power supply device 100 may include the priority of charging. For example, different user accounts may have different priorities depending on their level of payment or frequency of use, and the authorization code may also record information about priorities. In an embodiment, if the power supply device 100 is receiving a connection request from the power receiving device 104 while charging the power receiving device 102, the power supply device 100 can compare the priority between the power receiving devices 102 and 104, if the power receiving device 102 takes precedence. When the weight is higher than the power receiving device 104, the power supply device 100 does not accept the connection request from the power receiving device 104 and continues to charge the power receiving device 102. In another embodiment, if the power supply device 100 is receiving a connection request from the power receiving device 106 while charging the power receiving device 102, and the power receiving device 106 has a higher priority than the power receiving device 102, in this case, if the power supply device When the excess power output terminal is supplied to the power receiving device 106, the power supply device 100 stops charging the power receiving device 102, and accepts the connection request from the power receiving device 106 to start charging the power receiving device 106. In still another embodiment, when the power receiving devices 102 and 104 simultaneously transmit a connection request to the power supply device 100, the power supply device 100 can select a higher power receiving device to be connected and charged. It should be noted that the above priority may come from various situations, for example, when the power of a powered device is low, it may have a higher priority; or a user of a powered device may spend more money to purchase priority. The power to charge, but not limited to this. In addition to this, the owner of the power supply device 100 (for example, a store) may also specify that the power supply device 100 charges a specific power receiving device. It should be noted that the charging authority can record any information related to charging, so that the power supply device can determine whether to charge the power receiving device, and the information is not limited to the above authorization code, identity identification or priority.
值得注意的是，根據本創作之選擇性充電方法，供電裝置可依照接收到的充電權限資訊，以各種方式來進行充電對象的選擇。不同於習知技術中只要受電裝置與供電裝置接近即可相互配對並進行充電，本創作之選擇性充電方法除了需判斷受電裝置與供電裝置之間的距離外，供電裝置還需判斷受電裝置是否具有足夠的充電權限，滿足條件才對其進行充電，以達到選擇性充電的效果。如此一來，提供無線充電的公共場所或商店可將充電服務結合收費機制，以滿足電子裝置充電的服務與需求。It is worth noting that according to the selective charging method of the present invention, the power supply device can select the charging object in various ways according to the received charging authority information. Different from the prior art, as long as the power receiving device and the power supply device are close to each other and can be paired and charged, in addition to determining the distance between the power receiving device and the power supply device, the power supply device needs to determine whether the power receiving device needs to determine whether the power receiving device is Have sufficient charging authority to charge the battery to meet the selective charging effect. In this way, the public place or store that provides wireless charging can combine the charging service with the charging mechanism to meet the service and demand for charging the electronic device.
在上述實施例中，供電裝置與受電裝置進行配對的方式是由供電裝置持續發送廣播訊號，受電裝置偵測到廣播訊號之後傳送連線請求來進行配對。在此情形下，供電裝置所發送的廣播訊號亦可結合其它用途。舉例來說，若供電裝置設置於可提供無線充電服務的商店，其發送的廣播訊號可結合信標（Beacon）中的商品資訊。此外，店家亦可透過廣播訊號來傳遞其他訊息（如促銷或優惠訊息）至顧客的手機。在另一實施例中，供電裝置所傳送的廣播訊號亦可包含供電裝置的使用狀態，例如當供電裝置過熱或故障時，可將相關資訊夾帶在廣播訊號中，供電裝置之安裝者即可輕易得知其運作狀況並即時進行處理。除此之外，由於受電裝置往往是在電量不足而需要充電時才啟動搜尋廣播訊號的功能，若由受電裝置來發送廣播訊號，往往會造成多餘的耗電因而提早耗盡電量；相較之下，供電裝置係實體連接於電源供應端並由電源供應端來提供電力，由供電裝置來發送廣播訊號較不會發生耗盡電量的問題。In the above embodiment, the manner in which the power supply device and the power receiving device are paired is that the power supply device continuously transmits the broadcast signal, and the power receiving device detects the broadcast signal and transmits a connection request to perform pairing. In this case, the broadcast signal transmitted by the power supply device can also be combined with other uses. For example, if the power supply device is installed in a store that can provide a wireless charging service, the broadcast signal transmitted by the power supply device can be combined with the product information in the beacon. In addition, the store can also transmit other messages (such as promotions or offers) to the customer's mobile phone through broadcast signals. In another embodiment, the broadcast signal transmitted by the power supply device may also include the use state of the power supply device. For example, when the power supply device is overheated or faulty, the related information may be entrained in the broadcast signal, and the installer of the power supply device may easily Learn about its operation and deal with it immediately. In addition, since the power receiving device often starts the function of searching for the broadcast signal when the power is insufficient and needs to be charged, if the power receiving device transmits the broadcast signal, it often causes unnecessary power consumption and thus depletes the power earlier; The power supply device is physically connected to the power supply end and is powered by the power supply terminal, and the power supply device sends the broadcast signal less than the problem of depleting the power.
然而，在本創作中，供電裝置與受電裝置之運作方式不限於上述關於流程40及50的說明。舉例來說，請參考第6圖，第6圖為本創作實施例另一無線充電系統60之示意圖。如第6圖所示，無線充電系統60簡略地由一供電裝置600及受電裝置602、604及606所組成。其中，受電裝置602、604及606可發送廣播訊號，以供供電裝置600進行偵測及搜尋。供電裝置600與受電裝置602、604及606之詳細結構分別和供電裝置100與受電裝置102、104及106相同，且運作方式相似，於此不贅述。However, in the present creation, the operation mode of the power supply device and the power receiving device is not limited to the above description regarding the processes 40 and 50. For example, please refer to FIG. 6. FIG. 6 is a schematic diagram of another wireless charging system 60 according to the present embodiment. As shown in FIG. 6, the wireless charging system 60 is composed of a power supply device 600 and power receiving devices 602, 604, and 606. The power receiving devices 602, 604, and 606 can transmit broadcast signals for the power supply device 600 to detect and search. The detailed structures of the power supply device 600 and the power receiving devices 602, 604, and 606 are the same as those of the power supply device 100 and the power receiving devices 102, 104, and 106, respectively, and the operation modes are similar, and will not be described herein.
請參考第7圖，第7圖為本創作實施例一流程70之流程圖。流程70可用於一無線充電系統之一受電裝置，如第6圖所示之受電裝置602、604或606，用來執行選擇性無線充電方法。在一實施例中，流程70可實現於受電裝置602中的充電控制器310，其包含以下步驟：Please refer to FIG. 7. FIG. 7 is a flowchart of a process 70 of the first embodiment of the present invention. The process 70 can be used in a power receiving device of a wireless charging system, such as the power receiving device 602, 604 or 606 shown in FIG. 6, for performing a selective wireless charging method. In an embodiment, the process 70 can be implemented in the charge controller 310 in the power receiving device 602, which includes the following steps:
步驟700： 開始。Step 700: Start.
步驟702： 當受電裝置602欲進行充電時，持續發送一廣播訊號。Step 702: When the power receiving device 602 wants to perform charging, continuously transmitting a broadcast signal.
步驟704： 接收來自於無線充電系統60之供電裝置600之一連線請求，以與供電裝置600建立連線。Step 704: Receive a connection request from the power supply device 600 of the wireless charging system 60 to establish a connection with the power supply device 600.
步驟706： 告知供電裝置600受電裝置602欲進行充電。Step 706: Informing the power supply device 600 that the power receiving device 602 is to be charged.
步驟708： 當受電裝置602被判斷為具有一充電權限時，開始從供電裝置600接收電力。Step 708: When the power receiving device 602 is determined to have a charging authority, power is received from the power supply device 600.
步驟710： 結束。Step 710: End.
根據流程70，在無線充電系統60中，當受電裝置602欲進行充電時，會持續發送廣播訊號（步驟702），供電裝置則持續搜尋周圍是否存在廣播訊號。同樣地，廣播訊號可包含一種資料型態，供電裝置可根據資料型態來判斷受電裝置的存在。當供電裝置600搜尋到一廣播訊號包含可識別之資料型態其指示附近存在受電裝置602時，供電裝置600可判斷受電裝置602可與之配對並接收電力。接著，供電裝置600可根據廣播訊號之強度來判斷受電裝置602與供電裝置600之間的距離，例如可透過廣播訊號所包含的無線訊號強度指示來進行判斷。進一步地，供電裝置600可設定一臨界值（例如設定供電裝置600之可充電範圍為臨界值），並於判斷出受電裝置602與供電裝置600之間的距離小於臨界值時，主動與受電裝置602建立連線。舉例來說，供電裝置600可向受電裝置602發出一連線請求，當受電裝置602接受連線請求之後，兩者之間即可建立連線並進行通訊（步驟704）。在連線過程中，受電裝置602可告知供電裝置600其欲進行充電（步驟706），或者，受電裝置602亦可將欲充電的訊息夾帶在廣播訊號中，在此情形下，供電裝置600在建立連線之前即可接收到充電請求。According to the process 70, in the wireless charging system 60, when the power receiving device 602 is to be charged, the broadcast signal is continuously transmitted (step 702), and the power supply device continuously searches for whether there is a broadcast signal around. Similarly, the broadcast signal may include a data type, and the power supply device may determine the presence of the power receiving device according to the data type. When the power supply device 600 searches for a broadcast signal including an identifiable data type indicating that the power receiving device 602 is present nearby, the power supply device 600 can determine that the power receiving device 602 can be paired with and receive power. Next, the power supply device 600 can determine the distance between the power receiving device 602 and the power supply device 600 according to the strength of the broadcast signal, for example, by using the wireless signal strength indication included in the broadcast signal. Further, the power supply device 600 can set a threshold (for example, setting the chargeable range of the power supply device 600 to a critical value), and when determining that the distance between the power receiving device 602 and the power supply device 600 is less than a critical value, the active and power receiving devices 602 establishes a connection. For example, the power supply device 600 can issue a connection request to the power receiving device 602. After the power receiving device 602 accepts the connection request, a connection can be established and communication can be performed (step 704). During the connection process, the power receiving device 602 can inform the power supply device 600 that it wants to perform charging (step 706), or the power receiving device 602 can also carry the message to be charged in the broadcast signal. In this case, the power supply device 600 is A charging request can be received before the connection is established.
接著，透過供電裝置600與受電裝置602之間的連線及相互溝通，可進一步判斷兩者是否相容。相容代表供電裝置600與受電裝置602符合相同的無線充電規格，亦即，供電裝置600能夠對受電裝置602進行充電。接著，供電裝置600可判斷受電裝置602是否具有一充電權限，並據以決定是否對受電裝置602進行充電。供電裝置600可根據溝通過程中交換的資訊或廣播訊息中夾帶的資訊來判斷受電裝置602是否具有充電權限。當受電裝置602被判斷為具有充電權限時，供電裝置600即可開始供電，使得受電裝置602可從供電裝置600接收電力（步驟708）。相反地，當供電裝置600判斷受電裝置602不具有充電權限時，則不對受電裝置602進行充電。除此之外，供電裝置600亦可具有第2圖所繪示的電路結構或其它相似的結構，本領域具通常知識者可依照前述關於第2圖的說明，推知供電裝置600如何實現用於受電裝置602之選擇性充電方式，於此不贅述。Then, through the connection and communication between the power supply device 600 and the power receiving device 602, it can be further determined whether the two are compatible. The compatible representative power supply device 600 and the power receiving device 602 conform to the same wireless charging specification, that is, the power supply device 600 can charge the power receiving device 602. Next, the power supply device 600 can determine whether the power receiving device 602 has a charging authority and determine whether to charge the power receiving device 602. The power supply device 600 can determine whether the power receiving device 602 has charging authority according to information exchanged in the communication process or information carried in the broadcast message. When the power receiving device 602 is determined to have the charging authority, the power supply device 600 can start power supply, so that the power receiving device 602 can receive power from the power supply device 600 (step 708). Conversely, when the power supply device 600 determines that the power receiving device 602 does not have the charging authority, the power receiving device 602 is not charged. In addition, the power supply device 600 can also have the circuit structure shown in FIG. 2 or other similar structures. Those skilled in the art can infer from the foregoing description of FIG. 2 how the power supply device 600 can be implemented. The selective charging mode of the power receiving device 602 will not be described here.
上述關於流程70中供電裝置600之運作方式及相關說明可歸納為一流程80，如第8圖所示。流程80可用於一無線充電系統之一供電裝置，如第6圖所示之供電裝置600，用來執行選擇性無線充電方法。流程80可實現於供電裝置600中的充電控制器210，其包含以下步驟：The operation mode and related description of the power supply device 600 in the above process 70 can be summarized as a process 80, as shown in FIG. The process 80 can be used in a power supply device of a wireless charging system, such as the power supply device 600 shown in FIG. 6, for performing a selective wireless charging method. The process 80 can be implemented in the charging controller 210 in the power supply device 600, which includes the following steps:
步驟800： 開始。Step 800: Start.
步驟802： 搜尋無線充電系統60之受電裝置602所發送之一廣播訊號。Step 802: Search for a broadcast signal sent by the power receiving device 602 of the wireless charging system 60.
步驟804： 當偵測到廣播訊號時，根據廣播訊號之強度來判斷受電裝置602的存在，並判斷受電裝置602與供電裝置600之間之一距離。Step 804: When the broadcast signal is detected, the presence of the power receiving device 602 is determined according to the strength of the broadcast signal, and a distance between the power receiving device 602 and the power supply device 600 is determined.
步驟806： 當距離小於一臨界值時，與受電裝置602建立連線。Step 806: When the distance is less than a critical value, a connection is established with the power receiving device 602.
步驟808： 根據廣播訊號來判斷受電裝置602是否具有一充電權限，並據以決定是否對受電裝置602進行充電。Step 808: Determine whether the power receiving device 602 has a charging authority according to the broadcast signal, and accordingly determine whether to charge the power receiving device 602.
步驟810： 結束。Step 810: End.
同樣地，在充電過程中，供電裝置600可持續判斷受電裝置602與供電裝置600之間的距離。當判斷兩者之間的距離大於臨界值（如供電裝置600之可充電範圍）時，供電裝置600會停止供應電力至受電裝置602。如上所述，此臨界值亦可設定為供電裝置600的可充電範圍。此時，若受電裝置602仍處於電量不足的狀態，可再發送廣播訊號以找尋是否有其它供電裝置可提供電力。若受電裝置602之電量已足夠，則不再發送廣播訊號。透過上述方式，若受電裝置602為行動裝置時（如手機或平板電腦），使用者在判斷行動裝置之電量足夠時只需要移開行動裝置即可停止充電。Similarly, during the charging process, the power supply device 600 can continuously determine the distance between the power receiving device 602 and the power supply device 600. When it is determined that the distance between the two is greater than a threshold (such as the chargeable range of the power supply device 600), the power supply device 600 stops supplying power to the power receiving device 602. As described above, this threshold can also be set to the chargeable range of the power supply device 600. At this time, if the power receiving device 602 is still in a state of insufficient power, the broadcast signal can be resent to find out whether other power supply devices can provide power. If the power of the power receiving device 602 is sufficient, the broadcast signal is no longer transmitted. In the above manner, if the power receiving device 602 is a mobile device (such as a mobile phone or a tablet computer), the user only needs to remove the mobile device to stop charging when determining that the mobile device has sufficient power.
除此之外，在無線充電系統60及流程70、80中，充電權限可以是受電裝置102之優先權、受電裝置102取得之一授權碼、可用於充電之點數、或可用於充電之儲值金額或時間等。關於充電權限之詳細實現方式可參考前述說明，於此不贅述。值得注意的是，受電裝置602除了可在建立連線之後將其充電權限告知供電裝置600，亦可在建立連線之前，將充電權限夾帶於廣播訊息中，使得供電裝置600可透過廣播訊息來判斷受電裝置602是否具有足夠權限，進而決定是否對受電裝置602進行充電或是否與受電裝置602建立連線。同樣地，供電裝置600與受電裝置602之間的連線可透過任何無線通訊技術進行連線，連線方式可以是任何規格的通訊協定，如藍牙（Bluetooth）、藍牙低功耗（Bluetooth Low Energy，BLE）、無線相容性認證（Wireless Fidelity，Wi-Fi）或射頻（Radio Frequency，RF）訊號等，但不限於此。In addition, in the wireless charging system 60 and the processes 70, 80, the charging authority may be the priority of the power receiving device 102, the authorization code obtained by the power receiving device 102, the number of points available for charging, or the storage available for charging. Value amount or time, etc. For detailed implementation of the charging authority, refer to the foregoing description, and details are not described herein. It should be noted that the power receiving device 602 can not only inform the power supply device 600 of the charging authority after establishing the connection, but also entrain the charging authority in the broadcast message before establishing the connection, so that the power supply device 600 can transmit the message through the broadcast message. It is determined whether or not the power receiving device 602 has sufficient authority to determine whether to charge the power receiving device 602 or whether to establish a connection with the power receiving device 602. Similarly, the connection between the power supply device 600 and the power receiving device 602 can be connected through any wireless communication technology, and the connection method can be any standard communication protocol, such as Bluetooth, Bluetooth Low Energy (Bluetooth Low Energy) , BLE), Wireless Fidelity (Wi-Fi) or Radio Frequency (RF) signals, etc., but are not limited thereto.
詳細來說，無線充電系統10及60的差異僅在於發送廣播以及起始連線的對象不同。在無線充電系統10中，是由供電裝置100發送廣播訊號，受電裝置102搜尋廣播訊號並在偵測到廣播訊號時主動與供電裝置100進行連線。相較之下，在無線充電系統60中，是由受電裝置602發送廣播訊號，供電裝置600搜尋廣播訊號並在偵測到廣播訊號時主動與受電裝置602進行連線。一般來說，受電裝置往往是在電量不足時發送廣播訊號，較符合使用者的需求。舉例來說，受電裝置可在電量不足時產生一警示訊息並顯示一按鈕，使用者收到警示訊息後，可觸發按鈕以啟動發送廣播訊號之運作。受電裝置再接收供電裝置所回傳的訊息告知其所在位置，或透過其它方式（例如全球衛星定位系統（Global Positioning System，GPS））來取得附近供電裝置的所在位置。In detail, the difference between the wireless charging systems 10 and 60 is only that the objects that transmit the broadcast and the initial connection are different. In the wireless charging system 10, the broadcast signal is transmitted by the power supply device 100, and the power receiving device 102 searches for the broadcast signal and actively connects with the power supply device 100 when the broadcast signal is detected. In the wireless charging system 60, the power receiving device 602 searches for the broadcast signal and actively connects to the power receiving device 602 when the broadcast signal is detected. Generally speaking, the power receiving device often sends a broadcast signal when the power is insufficient, which is more suitable for the user. For example, the powered device can generate a warning message and display a button when the battery is low. After receiving the warning message, the user can trigger a button to initiate the operation of transmitting the broadcast signal. The powered device then receives the message sent back by the power supply device to inform its location, or obtains the location of the nearby power supply device by other means, such as a Global Positioning System (GPS).
此外，若由受電裝置發送廣播訊號時，受電裝置可直接在廣播訊號中夾帶任何無線充電運作所需的資訊，舉例來說，廣播訊號可夾帶充電權限的詳細內容，如前述授權碼或身分識別等。此外，廣播訊號亦可包含無線訊號強度指示，以供供電裝置判斷距離，或包含充電規格的相容性資訊。更明確來說，受電裝置所發送廣播訊號可包含任何欲提供予供電裝置的內容，使供電裝置能夠判斷是否與其建立連線並發送電力。本領域具通常知識者可根據不同無線通訊的特性或根據實際需求，採用無線充電系統10搭配流程40、50或無線充電系統60搭配流程70、80來實現本創作的選擇性充電方法。In addition, when the broadcast signal is transmitted by the power receiving device, the power receiving device can directly carry any information required for the wireless charging operation in the broadcast signal. For example, the broadcast signal can carry the detailed content of the charging authority, such as the foregoing authorization code or identity identification. Wait. In addition, the broadcast signal may also include a wireless signal strength indication for the power supply device to determine the distance or contain compatibility information of the charging specification. More specifically, the broadcast signal transmitted by the power receiving device may include any content to be provided to the power supply device, so that the power supply device can determine whether to establish a connection with it and transmit power. Those skilled in the art can implement the selective charging method of the present invention by using the wireless charging system 10 in conjunction with the processes 40, 50 or the wireless charging system 60 in conjunction with the processes 70, 80 according to the characteristics of different wireless communications or according to actual needs.
值得注意的是，本創作之實施例可達到無線充電的良好控制性。舉例來說，無論是由供電裝置或受電裝置發送廣播訊號，對應的接收端皆可根據接收到的廣播訊號強度來判斷廣播訊號發送端與接收端本身的距離，受電裝置即可藉由距離資訊來選擇最適合的供電對象。在一實施例中，當一受電裝置（如手機）欲進行充電並開啟廣播訊號之搜尋功能時，該手機可能同時接收到來自於多個供電裝置（如多個無線電源）的廣播訊號，此時，手機可根據各別廣播訊號的強度，分別判斷每一無線電源與手機之間的距離。在此情形下，手機可選擇發送連線請求至距離最近（即相對應廣播訊號強度最大）的無線電源，進而與該無線電源連線並進行充電。如此一來，手機可自行選擇最適合的供電對象，且無須額外以條列方式顯示附近存在的無線電源以供其使用者選擇，可避免使用者在不熟悉無線電源名稱的情況下選擇錯誤。此外，手機的使用者也無須透過手機顯示的列表或藉由掃描條碼（Bar Code）或快速響應矩陣碼（Quick Response Code，QR Code）的方式來選擇欲使用的無線電源，可實現良好的充電控制以及便利性。It is worth noting that the embodiment of the present invention can achieve good control of wireless charging. For example, whether the broadcast signal is sent by the power supply device or the power receiving device, the corresponding receiving end can determine the distance between the broadcast signal transmitting end and the receiving end itself according to the received broadcast signal strength, and the power receiving device can use the distance information. To choose the most suitable power supply object. In an embodiment, when a powered device (such as a mobile phone) wants to charge and turn on the search function of the broadcast signal, the mobile phone may simultaneously receive broadcast signals from multiple power supply devices (such as multiple wireless power sources). The mobile phone can determine the distance between each wireless power source and the mobile phone according to the strength of each broadcast signal. In this case, the mobile phone can select to send a connection request to the nearest wireless power source (ie, corresponding to the highest broadcast signal strength), and then connect and charge the wireless power source. In this way, the mobile phone can select the most suitable power supply object by itself, and does not need to additionally display the nearby wireless power supply for the user to select, which can prevent the user from making an error if he is not familiar with the wireless power source name. In addition, the user of the mobile phone does not need to select a wireless power source to be used through a list displayed on the mobile phone or by scanning a bar code or a Quick Response Code (QR Code), thereby achieving good charging. Control and convenience.
綜上所述，在本創作之選擇性充電方法中，供電裝置可對受電裝置進行充電權限的判斷，以實現關於無線充電的應用及服務。在一實施例中，可由供電裝置發送廣播訊號，當受電裝置偵測到廣播訊號時，主動與供電裝置進行連線，供電裝置進而判斷受電裝置是否具有充電權限，並據以決定是否對其進行充電。在另一實施例中，可由受電裝置發送廣播訊號，當供電裝置偵測到廣播訊號時，主動與受電裝置進行連線，供電裝置進而判斷受電裝置是否具有充電權限，並據以決定是否對其進行充電。上述選擇性充電方法可由充電控制器來實現，在受電裝置中，充電控制器可透過具有無線通訊功能的通訊單元以及處理器中的應用程式來實現；在供電裝置中，充電控制器可以內建或外接的方式設置，並可藉由任何類型的介面來控制電力的傳送，以實現選擇性充電方法。In summary, in the selective charging method of the present invention, the power supply device can determine the charging authority of the power receiving device to implement applications and services related to wireless charging. In an embodiment, the broadcast signal can be sent by the power supply device. When the power receiving device detects the broadcast signal, it actively connects with the power supply device, and the power supply device determines whether the power receiving device has the charging authority, and determines whether to perform the charging device. Charging. In another embodiment, the broadcast signal can be sent by the power receiving device. When the power supply device detects the broadcast signal, the power supply device actively connects with the power receiving device, and the power supply device determines whether the power receiving device has charging authority, and determines whether to Charge it. The above selective charging method can be implemented by a charging controller. In the power receiving device, the charging controller can be realized by a communication unit having a wireless communication function and an application in the processor; in the power supply device, the charging controller can be built in Or an external connection, and the transmission of power can be controlled by any type of interface to implement a selective charging method.
