基于上述移动终端硬件结构以及通信网络系统，提出本发明方法各个实施例。
第一实施例
如图3所示，本发明第一实施例提供一种无线充电控制方法，用于充电板，所述方法包括步骤：
31、当终端被放置到充电板上时，通过所述充电板的传感器侦测到所述终端在所述充电板的放置位置；
在本实施例中，传感器可为压力传感器，压力传感器内置在所述充电板中。
可以理解，当终端放置在充电板上时，所述终端会在放置的位置产生压力，此时通过内置的压力传感器感应压力，然后将感应到压力的区域作为所述终端在所述充电板的放置位置。
32、与所述终端建立通信连接，通过所述通信连接获取所述终端的参数信息；根据获取的所述终端的参数信息从云端服务器中获取所述终端的接收线圈的位置；
在本实施例中，充电板可与所述终端建立通信连接，所述通信连接方式可包括蓝牙连接方式、红外连接模式、WiFi连接方式或者其他近距离连接方式。充电板还可与云端服务器建立通信连接，该通信连接方式可以为无线连接方式，也可以为有线连接方式，在此不作限制。
在本实施例中，所述终端的参数信息包括终端的型号信息、终端的识别码信息。通常终端在出厂时，终端的接收线圈的位置已经固定了，通过终端的参数信息，可确定终端及其接收线圈的位置。
云端服务器中可预先存储终端的参数信息以及其相对应的接收线圈的位置信息，预先存储的方式在此不作限制，例如可以由终端上传到云端服务器中。
充电板可将获取的所述终端的参数信息通过通信连接向云端服务器发送查询请求，云端服务器接收到充电板的查询请求之后，根据终端的参数信息匹配到相对应的接收线圈的位置信息并发送给所述充电板。
33、根据所述终端在所述充电板的放置位置和所述终端的接收线圈的位置生成第一移动指令；根据生成的第一移动指令控制所述充电板的充电线圈进行移动，以使得所述充电线圈与所述接收线圈对准，所述充电线圈在充电状态下生成的感应磁场对所述终端进行充电。
在本实施例中，充电板的充电线圈可通过控制器进行控制，使得充电线圈移动并与接收线圈对准。充电线圈移动的方位及距离可通过控制器生成的第一移动指令确定，第一移动指令由所述终端在所述充电板的放置位置和所述终端的接收线圈的位置确定。
作为示例地，以下以手机为例进行说明：
当手机被随意地放置到充电板上时，这时可通过充电板的传感器侦测到手机在充电板的放置位置。
由于手机是随意地放置，因此需要调整充电线圈的位置与接收线圈进行对准。在调整充电线圈的位置之前，充电板需要获取到手机的接收线圈的位置（手机的接收线圈通常设置在手机的背面）。因此充电板与手机建立通信连接，通过通信连接获取手机的型号信息，然后根据手机的型号信息从云端服务器中获取手机的接收线圈的位置。
确定手机的接收线圈的位置、手机在充电板的放置位置之后，可根据充电线圈当前的位置，控制充电线圈进行移动。具体地，可将手机的接收线圈的位置、手机在充电板的放置位置以及充电线圈当前的位置转换为位置坐标，然后根据位置坐标确定充电线圈移动的方位及距离。
在充电线圈与接收线圈对准之后，即可对手机进行充电。
请参考图4所示，在另一种实施方式中，所述方法还包括步骤：
34、通过所述通信连接获取所述终端的充电效率信息；
35、判断所述终端的充电效率是否大于预设阈值；
36、若所述终端的充电效率不大于预设阈值，则根据所述终端在所述充电板的放置位置、所述终端的接收线圈的位置以及所述终端的充电效率信息生成第二移动指令，并根据生成的第二移动指令控制所述充电板的充电线圈进行移动。
在该实施方式中，通过充电效率来控制充电线圈进行移动，能进一步地确保以较高的充电效率对线圈进行充电。
进一步地，所述充电线圈为金属点阵，所述金属点阵包括多个金属点，所述金属点阵中相邻的金属点通过可控开关连接；所述根据生成的第一移动指令控制所述充电板的充电线圈进行移动，以使得所述充电线圈与所述接收线圈对准，所述充电线圈在充电状态下生成的感应磁场对所述终端进行充电包括步骤：
根据生成的第一移动指令，驱动所述金属点阵区域内的可控开关导通形成充电线圈，以使得形成的充电线圈与所述接收线圈对准，形成的充电线圈在充电状态下生成的感应磁场对所述终端进行充电。
本发明实施例提供的一种无线充电控制方法，通过终端在充电板的放置位置和终端的接收线圈的位置生成移动指令，根据生成的移动指令控制充电线圈进行移动，以使得充电线圈与接收线圈对准；可让充电线圈自动适应终端的接收线圈的位置，方便使用，而且能确保以较高的充电效率对线圈进行充电。

在本实施例中，传感器410可为压力传感器，压力传感器内置在所述充电板中。可以理解的，传感器410可集成在检测模块41中。
还可以理解，当终端放置在充电板上时，所述终端会在放置的位置产生压力，此时通过内置的压力传感器感应压力，然后将感应到压力的区域作为所述终端在所述充电板的放置位置。

在本实施例中，通过所述通信模块42，充电板可与所述终端建立通信连接，所述通信连接方式可包括蓝牙连接方式、红外连接模式、WiFi连接方式或者其他近距离连接方式。充电板还可与云端服务器建立通信连接，该通信连接方式可以为无线连接方式，也可以为有线连接方式，在此不作限制。
在本实施例中，所述终端的参数信息包括终端的型号信息、终端的识别码信息。通常终端在出厂时，终端的接收线圈的位置已经固定了，通过终端的参数信息，可确定终端及其接收线圈的位置。
云端服务器中可预先存储终端的参数信息以及其相对应的接收线圈的位置信息，预先存储的方式在此不作限制，例如可以由终端上传到云端服务器中。
充电板可将获取的所述终端的参数信息通过所述通信模块42向云端服务器发送查询请求，云端服务器接收到充电板的查询请求之后，根据终端的参数信息匹配到相对应的接收线圈的位置信息并发送给所述充电板。
所述控制器43，用于根据所述检测模块41侦测到的所述终端在所述充电板的放置位置和所述通信模块42获取的所述终端的接收线圈的位置生成第一移动指令；根据生成的第一移动指令控制所述充电线圈44进行移动，以使得所述充电线圈44与所述接收线圈对准，所述充电线圈44在充电状态下生成的感应磁场对所述终端进行充电。

以手机为例：当手机被随意地放置到充电板上时，这时可通过充电板的传感器侦测到手机在充电板的放置位置。
由于手机是随意地放置，因此需要调整充电线圈的位置与接收线圈进行对准。在调整充电线圈的位置之前，充电板需要获取到手机的接收线圈的位置（手机的接收线圈通常设置在手机的背面）。因此充电板与手机建立通信连接，通过通信连接获取手机的型号信息，然后根据手机的型号信息从云端服务器中获取手机的接收线圈的位置。
确定手机的接收线圈的位置、手机在充电板的放置位置之后，可根据充电线圈当前的位置，控制充电线圈进行移动。具体地，可将手机的接收线圈的位置、手机在充电板的放置位置以及充电线圈当前的位置转换为位置坐标，然后根据位置坐标确定充电线圈移动的方位及距离。
在充电线圈与接收线圈对准之后，即可对手机进行充电。
在另一种实施方式中，所述通信模块42，还用于通过所述通信连接获取所述终端的充电效率信息；
所述控制器43，还用于根据所述通信模块42获取的所述终端的充电效率信息，判断所述终端的充电效率是否大于预设阈值；若所述终端的充电效率不大于预设阈值，则根据所述终端在所述充电板的放置位置、所述终端的接收线圈的位置以及所述终端的充电效率信息生成第二移动指令，并根据生成的第二移动指令控制所述充电线圈44进行移动。
