本发明进一步提出一种基于磁共振的无线充电方法,应用于充电设备。
参照图2,图2为本发明的基于磁共振的无线充电方法一实施例的流程图。
在本实施例中,该无线充电方法包括以下步骤:
S10:当检测到电源输入时,寻呼或扫描可充电范围内的待充电终端;
S20:当寻呼或扫描到待充电终端并与之建立WiFi连接时,随机配置一送电谐振频率;
S30:基于WiFi通信协议将所述送电谐振频率发送给所述待充电终端,供所述待充电终端调整受电频率;
S40:当检测到所述受电频率与所述送电谐振频率相同时,按照所述送电谐振频率对所述待充电终端进行充电。
基于磁共振的无线充电方式的原理与声音共振的原理相同,排列好振动频率相同的音叉,一个发声的话,其他的也会共振发声,同样地,排列好在磁场中的相同频率的线圈,也可以从一个向另一个供电,也即在送电线圈的送电频率与受电线圈的受电频率相同时,受电终端可以基于非接触方式获得充电设备向外部辐射的能量,相比于电磁感应方式,利用共振可延长传输距离,磁共振方式不同于电磁感应方式,无需送电线圈和受电线圈的位置完全吻合。磁共振方式由能量发送装置,如充电设备,和能量接收装置,如待充电终端组成,当充电设备与待充电终端的谐振频率相同时,或者说在一个特定的频率上共振,它们就可以交换彼此的能量,实现充电设备向待充电终端充电。但是,现有的充电设备一般都是以固定频率向外辐射能量,在所述充电设备的可充电范围内的所有待充电终端可以轻易接受到所述充电设备辐射的能量,使得用户在使用充电设备为自己的终端设备充电时充电效率大幅降低,影响了用户体验。
在本实施例中,为了提高充电设备的充电效率,在检测到电源输入时,也即用户将充电设备接入电源时,充电设备上的电源检测模块会检测到电源输入,进而将该信号反馈至充电设备的处理器,当所述处理器接收到所述电源输入信号时,控制WiFi模块启动,自动搜索可充电范围内的WiFi信号或者通过辐射一能量信号再通过接收到的响应信息判断可充电范围内的待充电终端。当所述充电设备为连接WiFi路由器的一终端设备时,在充电设备接入电源后,扫描可充电范围内WiFi路由器辐射的WiFi信号,并且可以根据根据所述WiFi路由器查找可充电范围内是否存在连接所述WiFi路由器的待充电终端;当所述充电设备为WiFi热点的创建者时,在充电设备接入电源后,以跳频方式寻呼要接入所述WiFi热点的待充电终端,待充电终端在扫描到该寻呼信号时,可以做出相应的响应,所述充电设备在接收到该响应时,会向所述待充电终端发送一连接请求的要约,并在待充电终端反馈密钥信息后根据所述密钥允许所述待充电终端接入所述WiFi热点,并与之建立WiFi通信连接。
当充电设备寻呼或扫描到待充电终端时,根据密钥验证建立充电设备与待充电终端之间的直接连接,或者通过辐射WiFi信号的路由器建立充电设备与待充电终端之间的间接连接,并在充电设备与待充电终端建立WiFi连接后,按照预先内置于充电设备的设定程序生成一送电频率指令,根据所述送电频率指令随机配置一送电谐振频率,所述送电谐振频率在充电设备的最优充电效率范围内取值,以提高充电设备的充电效率。
由于充电设备与待充电终端已经基于WiFi通信协议建立连接,在充电设备输出所述送电谐振频率后,可以根据充电设备与待充电终端之间的WiFi通信连接将所述送电谐振频率发送给待充电终端,以便所述待充电终端以所述送电谐振频率为参照将自身的受电频率调至所述送电谐振频率,进而接收所述充电设备辐射的能量,防止其他用户获知该送电谐振频率后盗用所述充电设备辐射的能量,使所述充电设备的充电效率大幅降低,影响用户体验。
所述待充电终端在接收到所述充电设备发送的送电谐振频率后,开始对自身的受电频率进行调整,以将所述受电频率调至与所述送电谐振频率相同的频率,在所述受电频率与所述送电谐振频率相同时,二者发生共振,所述待充电终端就能够接收到充电设备以所述送电谐振频率向外辐射的能量,所述待充电终端就能够接到所述充电设备辐射的能量进行充电。
本发明实施例的基于磁共振的无线充电方法,用于充电设备以无线方式对待充电终端进行充电,在充电设备接入电源后,寻呼或扫描可充电范围内的待充电终端,当寻呼或扫描到待充电终端并与之建立WiFi连接时,随机配置一送电谐振频率,并将所述送电谐振频率发送给待充电终端,供所述待充电终端调整受电频率,在所述受电频率调至与所述送电谐振频率相同时,按照所述送电谐振频率对所述待充电终端进行充电。该无线充电方法通过充电设备与待充电终端之间建立的WiFi通信连接,将随机配置的送电谐振频率发送给待充电终端,供所述待充电终端调整受电频率,并在所述受电频率与所述送电谐振频率相同时,开始对所述待充电终端进行充电,避免了其他用户轻易获取所述送电谐振频率对其终端设备进行充电、造成充电效率大幅降低的情形,提高了充电设备的充电效率。
进一步地,参照图3,基于上述实施例的无线充电方法,步骤S10的第一实施例,具体包括:
S11a:当检测到电源输入时,扫描可充电范围内的WiFi信号,并检测可充电范围内是否存在待充电终端;
S12a:接入可充电范围内的最强WiFi信号,并在检测到待充电终端时,获取所述待充电终端接入的WiFi信号。
在本实施例中,所述充电设备作为一连接WiFi路由器的一终端设备,在检测到电源接入,并开启WiFi功能时,按照预设程序扫描可充电范围内的WiFi信号,所述WiFi信号由室内或家居系统中的WiFi路由器或其他智能网关发出,并且可根据所述WiFi路由器或智能网关中的连接终端的标识信息查找可充电范围内是否存在待充电终端,为了保证WiFi连接的稳定性,在充电设备扫描到可充电范围内存在可连接的WiFi信号时,接入可充电范围内信号强度最强的WiFi信号,并在检测到待充电终端时,获取所述待充电终端接入的WiFi信号。
进一步地,参照图4,基于上述实施例的无线充电方法,步骤S20的第一实施例,具体包括:
S21a:将获取的待充电终端接入的WiFi信号与所述最强WiFi信号进行比对;
S22a:当二者完全一致时,通过所述最强WiFi信号建立二者之间的通信连接,并随机配置一送电谐振频率。
在本实施例中,在根据充电设备接收到的反馈信息获取到待充电设备接入的WiFi信号后,可以将其与充电终端连接的WiFi信号进行比对,当二者接入的WiFi信号是同一WiFi信号时,可以通过所述最强WiFi信号建立通信连接,该通信连接经由辐射所述最强WiFi信号的路由器或智能网关中转处理,可以实现充电设备与待充电终端之间的数据交互,在充电设备与待充电终端建立WiFi连接后,按照预先内置于充电设备的设定程序生成一送电频率指令,根据所述送电频率指令随机配置一送电谐振频率,所述送电谐振频率在充电设备的最优充电效率范围内取值,以提高充电设备的充电效率。
进一步地,参照图5,基于上述实施例的无线充电方法,步骤S10的第二实施例,具体包括:
S11b:当检测到电源输入时,检测可充电范围内是否存在待充电终端;
S12b:当检测到待充电终端时,以跳频方式寻呼可充电范围内的待充电终端。
在本实施例中,所述充电设备作为WiFi热点的创建者,在检测到电源输入后,向外辐射一能量信号,以检测可充电范围内是否存在待充电终端,当所述待充电终端接收到所述能量信号后会做出响应,根据所述响应充电设备可以检测出可充电范围内存在待充电终端,接着所述充电设备可以启动WiFi功能,创建一WiFi热点,然后以跳频方式寻呼可充电范围内的待充电终端,可充电范围内的待充电终端可以针对所述寻呼做出响应,所述充电设备在接收到该响应时,会向所述待充电终端发送一连接强求的要约,并在待充电终端反馈密钥信息后根据所述密钥允许待充电终端接入所述WiFi热点,并与之建立WiFi通信连接。
进一步地,参照图6,基于上述实施例的无线充电方法,步骤S20的第二实施例,具体包括:
S21b:当接收到待充电终端反馈的响应信息时,向所述待充电终端发送连接请求;
S22b:当接收到所述待充电终端反馈的密钥信息并验证成功时,与所述待充电终端建立WiFi连接,并随机配置一送风谐振频率。
在本实施例中,在充电设备以跳频方式寻呼可充电范围内的待充电终端时,所述待充电终端每间隔预设时长扫描WiFi信号传输距离内的WiFi信号,当所述待充电终端扫描到充电设备的寻呼时,做出响应,当所述充电设备接受的到待充电终端反馈的响应信息时,向所述待充电终端发送一连接请求,而待充电终端在接收到所述连接请求后,可以接受所述连接请求,并携带密钥信息反馈至充电设备进行验证,当验证成功时,与所述待充电终端建立WiFi连接,并按照预先内置于充电设备的设定程序生成一送电频率指令,根据所述送电频率指令随机配置一送电谐振频率,所述送电谐振频率在充电设备的最优充电效率范围内取值,以提高充电设备的充电效率。
进一步地,参照图7,基于上述实施例的无线充电方法,步骤S30,具体包括:
S31:基于WiFi通信协议获取所述待充电终端的标识信息,并根据所述标识信息建立充电设备与待充电终端之间的通信信道;
S32:将所述标识信息和送电谐振频率信息打包后通过所述通信信道发送给所述待充电终端,供所述待充电终端调整受电频率。
在本实施例中,在充电设备与待充电终端之间建立WiFi通信连接后,基于待充电终端绑定在WiFi路由器或充电设备,或WiFi网络的网络协议层的设备信息,可以获取所述待充电终端的标识信息,并根据所述标识信息建立充电设备与待充电终端之间的通信信道,如tcp,然后将获取的待充电终端的标识信息和充电设备输出的送电谐振频率信息进行TCP打包或http打包,然后通过充电设备与待充电终端之间预先建立的通信信道传输至待充电终端,以便所述待充电终端以所述送电谐振频率为参照将自身的受电频率调至所述送电谐振频率,进而接收所述充电设备辐射的能量,防止其他用户获知该送电谐振频率后盗用所述充电设备辐射的能量,使所述充电设备的充电效率大幅降低,影响用户体验。
进一步地,参照图8,基于上述实施例的无线充电方法,步骤S40,具体包括:

S42:当所述受电频率与所述送电谐振频率相同时,生成充电指令;
S43:根据所述充电指令,以所述送电谐振频率为工作频率对所述待充电终端进行充电。
在本实施例中,在将所述送电谐振频率通过充电设备与待充电终端之间预先建立的通信信道发送给待充电终端后,所述待充电终端参照所述送点谐振频率对自身的受电频率进行调整,为了保证在最短的时间内实现充电设备向所述待充电终端进行充电,以提高充电设备的充电效率,充电设备通过所述WiFi通信连接实时监控所述待充电终端的受电频率变化,当所述受电频率调至与所述送电谐振频率相同时,生成相应的充电指令,然后充电设备就可以根据所述充电指令以所述送电谐振频率为工作频率向外部辐射能量,而此时由于待充电终端的受电频率与所述工作频率相同,则所述待充电终端可以接收到该频率的辐射能量,进而实现无线充电。
进一步地,在按照所述送电谐振频率对所述待充电终端进行充电的步骤之后,该无线充电方法还包括:
当检测到所述待充电终端接入充电线时,将当前的无线充电方式切换为有线充电方式。
在本实施例中,所述充电设备还支持优先充电模式,也即所述充电设备可以通过数据连接线对所述待充电终端进行优先充电,同时若待充电终端也支持有线充电模式和无线充电模式,则当待充电中观进行无线充电时,若用户使用该充电设备的优先充电接口进行有线充电时,需要将当前的无线充电方式切换为有线充电方式。当然,不一定必须是充电设备具有有线充电接口,所述待充电终端实现有线充电还可以依赖于其他充电设备的数据线接入,如果是其他充电设备的充电数据线接入,则可以切断所述充电设备的电源接入了,以节省能耗。
进一步地,在执行所有步骤之后,该无线充电方法还包括:
当接收到待充电终端反馈的充电完成信号时,控制所述充电设备进入待机状态或断电状态。
在本实施例中,在对所述待充电终端进行充电的过程中,实时监测所述待充电终端的电量信息,以便在待充电终端的电量满负荷时向所述充电设备反馈充电完成信号,从而便于充电设备接收到所述充电完成信号时,控制所述充电设备进入待机状态或切断所述充电设备的电源输入,以节省能耗,本实施例在接收到待充电终端反馈的充电完成信号后,停止对所述待充电终端充电,避免了待充电终端充满后过充的问题,延长了待充电终端的电池使用寿命。
