NFC通讯控制方法、装置、设备及计算机存储介质 技术领域
本申请涉及无线充电技术领域，尤其涉及一种NFC通讯控制方法、装置、设备及计算机存储介质。
背景技术
随着终端电子设备的快速发展，电子设备对电池电量的需求越来越高，因此电子设备的日常充电需求也越来越频繁。目前，大部分的电子设备充电方案都是通过触点接触进行充电，即电子设备上有一个设备触点，该设备触点上设置充电芯片，通过与其他电源设备进行触点接触，从而实现设备充电，同时电子设备在充电过程中，会通过触点与电源设备进行数据通讯，并根据通讯结果调整充电方式，从而为电子设备提供灵活的充电方案。
但是，以上这种通过触点接触实现电子设备与电源设备进行通讯的方式有很大的缺陷，例如触点是金属元件，而金属元件老化会降低导电性能，并且触点在充电芯片的充电插拔过程中可能发生磨损，影响触点正常的数据通讯功能。因此传统的触点接触的通讯方式容易劣化电子设备与电源设备之间的通讯功能，从而降低电子设备与电源设备之间的通讯效率，影响充电方式的正常调整，进而降低充电效率，影响电子设备的正常使用。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实 施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例方案的主要思路是：若检测到电子设备的NFC通讯请求，则基于NFC无线通讯获取所述电子设备的设备信息；获取所述设备信息的第一充电请求信息，并根据所述第一充电请求信息确定第一充电射频功率；根据所述第一充电射频功率启动预设的充电射频场，以供所述电子设备进行充电。通过以上方案，本申请将传统的触点接触通讯的方式，转换为NFC通讯控制的方式，使得电子设备与电源设备之间可以通过NFC通讯进行数据通讯，避免传统的触点接触通讯因触点金属老化或触点磨损造成数据通讯异常的情况发生，进而提升电子设备与电源设备之间的数据通讯效率，确保电子设备与电源设备之间充电数据的正常交互，从而保障电源设备能够实时根据电子设备的充电数据调整充电方式，进而提升充电效率，保障电子设备的正常使用。
本申请实施例考虑到，由于现有技术中，充电触点是金属元件，而金属元件老化会降低导电性能，并且触点在充电芯片的充电插拔过程中可能发生磨损，影响触点正常的数据通讯功能。因此传统的触点接触的通讯方式容易劣化电子设备与电源设备之间的通讯功能，从而降低电子设备与电源设备之间的通讯效率，影响充电方式的正常调整，进而降低充电效率，影响电子设备的正常使用。
本申请提供一种解决方案，通过所述方案，本申请将传统的触点接触通讯的方式，转换为NFC通讯控制的方式，使得电子设备与电源设备之间可以通过NFC通讯进行数据通讯，避免传统的触点接触通讯因触点金属老化或触点磨损造成数据通讯异常的情况发生，进而提升电子设备与电源设备之间的数据通讯效率，确保电子设备与电源设备之间充电数据的正常交互，从而保障电源设备能够实时根据电子设备的充电数据调整充电方式，进而提升充电效率，保障电子设备的正常使用。

基于上述硬件结构，提出本申请NFC通讯控制方法实施例。
本申请提供一种NFC通讯控制方法，在NFC通讯控制方法一实施例中，参照图2，所述NFC通讯控制方法包括：
步骤S10，若检测到电子设备的NFC通讯请求，则基于NFC无线通讯获取所述电子设备的设备信息；
步骤S20，获取所述设备信息的第一充电请求信息，并根据所述第一充电请求信息确定第一充电射频功率；
步骤S30，根据所述第一充电射频功率启动预设的充电射频场，以供所述电子设备进行充电。
该NFC通讯控制方法主要应用于电源设备上，所述方法中所涉及的设备可以是移动终端(如手机与充电宝、平板电脑与充电电源等)，穿戴式设备(如智能手环手环与充电宝、TWS耳机与充电盒、智能眼镜与充电盒等)， 固定终端(如智能风扇与电源、智能净水器与电源等)等，所述具体内容如下：
步骤S10，若检测到电子设备的NFC通讯请求，则基于NFC无线通讯获取所述电子设备的设备信息；
本申请中，电子设备与电源设备不采用传统的触点接触的方式进行数据交互，而是利用NFC通讯模块进行数据交互。NFC(Near Field Communication，近场通信)，是一种通过非接触式射频识别(RFID)及互连互通技术整合演变而来的数据通讯技术，通过在单一芯片上集成感应式读卡器、感应式卡片和点对点通信的功能，利用移动终端实现移动支付、电子票务、门禁、移动身份识别、防伪等应用。
在电子设备与电源设备中均设置有NFC通讯模块，电子设备与电源设备可通过NFC通讯模块实现二者之间的数据交互。因此，电子设备与电源设备之间的充电数据交互也可通过NFC通讯方式实现。由于NFC通讯属于无线通讯，因此电源设备在获取到电子设备的NFC通讯请求后，将通过NFC无线通讯获取到电源设备的设备信息。所述设备信息指的是当前电子设备的设备状态信息。
进一步地，所述若检测到所述电子设备的NFC通讯请求，则基于NFC无线通讯获取所述电子设备的设备信息的步骤包括：
步骤A1，若检测到所述电子设备的NFC通讯请求，则获取当前的第一NFC通讯版本，并根据所述NFC通讯请求中获取所述电子设备的第二NFC通讯版本；
步骤A2，若所述第一NFC通讯版本与所述第二NFC通讯版本不一致，则向所述电子设备发送NFC通讯版本更新的第二提示信息；
步骤A3，若所述第一NFC通讯版本与所述第二NFC通讯版本一致，则基于NFC无线通讯获取所述电子设备的设备信息。
若电子设备和电源设备的NFC通讯版本不一致，则容易产生二者的充电通讯数据异常。因此，电源设备需要在获取电子设备的设备信息之前，确保二者的NFC通讯版本一致，电源设备获取当前自身的第一NFC通讯版本，并通过解析出NFC通讯请求中包含的电子设备的第二NFC通讯版本。电源设备对第一NFC通讯版本和第二NFC通讯版本进行比对，若二者不一致，则向所 述电子设备提示进行NFC通讯版本更新的提示信息，电子设备的芯片在出厂时烧入了最新版本的NFC通讯版本，并且可通过与电源设备的通讯过程获取电源设备上的NFC通讯版本数据包，以保障实时更新。
步骤S20，获取所述设备信息的第一充电请求信息，并根据所述第一充电请求信息确定第一充电射频功率；
电源设备在获取到设备信息时，解析获取到设备信息中的第一充电请求信息，所述第一充电请求信息中指的是当前电子设备的所需充电电量，所需充电电压，所述充电模式，所述充电功率等等所需充电的规格信息。电源设备可根据第一充电请求信息调整自身的充电芯片，以符合当前电子设备的充电规格。例如，第一充电请求信息中指定了电子设备当前所需的充电规格为直流电压为5V，直流电流为2A，充电模式为静态充电模式。那么电源设备将根据第一充电请求信息对充电芯片进行规格限定，以得到符合电源设备规定的第一充电射频功率为P＝UI＝5*2＝10W。电子设备通过第一充电请求信息向电源设备指定了向电子设备进行充电时所需的功率为第一充电射频功率。电源设备根据第一充电请求信息进行充电芯片的参数调整，并根据第一充电请求信息中电子设备的规格信息确定电源设备向电子设备的充电功率。
进一步地，所述获取所述设备信息的第一充电请求信息的步骤包括：
步骤B1，检测到设备信息的充电状态；
步骤B2，判断所述充电状态中是否存在外设充电信息；
步骤B3，若是，则基于NFC无线通讯拒绝所述NFC通讯请求；
步骤B4，若否，则获取所述设备信息的第一充电请求信息。
电源设备在向所述电子设备进行充电的过程中，获取设备信息中的充电状态，所述充电状态中包括了当前的充电设备状态信息，充电电压信息等等。在本实施例中，电子设备可以支持多种充电方式，例如通过NFC无线通讯与电源设备进行射频场充电，通过QI协议的充电板进行感应充电等等。假设此时用户通过外部设备对电子设备进行充电，那么当前电子设备既通过外设进行充电补充电量，又通过电源设备的射频场补充电量。如果通过两种充电补充电量则容易造成电子设备出现意外事故，因此在检测到充电状态中包含有外设充电信息时，证明当前有两种或多种充电方式在对电子设备进行电量补充，此时，电源设备需要通过NFC无线通讯拒绝电子设备的NFC通讯请求， 以避免发生意外；若充电状态中没有外设充电信息，则证明电子设备当前可通过电源设备进行充电，此时获取设备信息中的第一充电请求信息。
步骤S30，根据所述第一充电射频功率启动预设的充电射频场，以供所述电子设备进行充电。
正常情况下，电源设备在接收到电子设备的充电请求时，将会向电子设备进行充电。在本实施例中，电源设备向电子设备进行充电的方式是通过充电射频场发射电磁感应磁场，由电子设备在线圈中感应到并整流过滤，从而使得电子设备得到电量。因此电源设备在获取到第一充电射频功率后，将启动电源设备设备自身预设的充电射频场，并通过充电芯片确定的第一充电射频功率确定调整当前的充电射频场的磁场强度，磁场方向等等。这样，电源设备能够在与电子设备进行NFC通讯的过程中，确定是否对电子设备进行充电，以及电子设备所需要的充电功率，并通过充电芯片对充电射频厂进行参数调整，以达到充电功率，以供电子设备进行充电。
进一步地，为方便理解，以下将通过举例对本申请进行解释说明：
参照图3，图3中所示电子设备为TWS耳机(Listener)，所示电源设备为充电盒(Poller)，充电盒中有两颗芯片：Application Processor和NFC Poller，Application Processor利用NFC Poller控制NFC无线充电以及接收TWS耳机中NTAG芯片发送过来的数据，充电盒中充电电源可来自于电池和USB。在TWS耳机中有NTAG、MCU以及CHARGER 3颗芯片，NTAG芯片用于与充电盒进行无线充电的协议交互，并且将交互信息传送给MCU芯片；MCU芯片用于处理TWS耳机所有信息控制指令，可以根据CHARGER芯片的状态信息，判断下一步的充电功率等信息并且利用NTAG芯片将控制信息传送给充电盒。CHARGER芯片保存当前TWS耳机电池电量的状态信息。
具体地，TWS耳机通过MCU芯片控制NTAG芯片向充电盒发射NFC通讯请求，充电盒通过NFC Poller芯片接收到NFC通讯请求后，得到NFC通讯请求中的设备信息。设备信息中包括第一充电请求信息，例如TWS耳机所需充电的规格信息，而根据第一充电请求信息，充电盒能够在Application Processor的控制下调整自身的充电参数，以适应TWS耳机所需充电的规格信息，达到TWS耳机所需要的第一充电射频功率。例如第一充电请求信息中指代了当前TWS耳机需要静态充电模式，即需要大电压大电流的高功率充电模式，此时 充电盒将根据高功率充电模式的充电需求调整当前充电盒中射频场的充电参数，使得射频场调整至高功率充电输出模式，以供TWS耳机实现高功率充电。
进一步地，所述根据所述第一充电射频功率启动预设的充电射频场，以供所述电子设备进行充电的步骤包括：
步骤C1，获取当前的可供充电射频功率；
步骤C2，若所述可供充电射频功率小于所述第一充电射频功率，则基于NFC无线通讯向所述电子设备发送功率不足的第一提示信息；
步骤C3，若所述可供充电射频功率大于或等于所述第一充电射频功率，则根据所述第一充电射频功率启动预设的充电射频场，以供所述电子设备进行充电。
所述可供充电射频功率指的是电源设备在保障自身设备能够正常运行的情况下所能提供给电子设备的充电功率。在本实施例中，保障电源设备能够正常运行的标准是电源设备为电子设备提供符合要求的电能功率之后，依旧能够在预设时间内正常执行自身的设备功能，例如即使电源设备为电子设备提供了符合耳机规格的10W功率电量之后，依旧能够在15分钟之内保持正常工作。那么所述10W功率电量即为当前电源设备的可供充电射频功率。
现实情况中，电源设备不一定能够为电子设备提供足够的充电功率，例如电子设备的第一充电请求信息指代了第一充电射频功率为15W，而当前电源设备根据电量情况所调整后的充电参数所能给出的最大功率仅为5W。也就是说，所述可供充电射频功率小于所述第一充电射频功率，当前电源设备无法为电子设备提供足够的输出充电功率，即使电源设备为电子设备进行充电，也无法提供足够的电量，同时，电源设备可能因为自身设备电量不足而无法正常使用。故基于NFC无线通讯获取到的第一充电射频功率，将与电源设备自身的可供充电射频功率进行比对，并根据比对结果进行充电控制。
电源设备检测到可供充电射频功率小于第一充电射频功率时，将基于NFC无线通讯向所述电子设备发送功率不足的第一提示信息，以供电子设备根据第一提示信息进行耳机功耗的调整或者提示用户进行人工充电的方式补充电量。所述第一提示信息还可以包括强制充电触发按钮，即当前电子设备需要紧急接听某个信息，具有紧急时效性，那么可触发第一提示信息上的强制充电触发按钮，生成强制充电指令，并基于NFC无线通讯技术传输至电源 设备，以强制电源设备启动充电射频场对电子设备进行充电。
进一步地，若可供充电射频功率大于或等于所述第一充电射频功率，证明当前电源设备能够为电子设备提供足够的充电功率，同时不影响到电源设备设备本身的正常运行。例如当前电源设备根据第一充电请求确定第一充电射频功率为10W，而当前电源设备的可供充电射频功率为11W，可供充电射频功率大于第一充电射频功率，此时，电源设备将根据第一充电射频功率启动预设的充电射频场，为电子设备进行充电。
本申请中，若检测到电子设备的NFC通讯请求，则基于NFC无线通讯获取所述电子设备的设备信息；获取所述设备信息的第一充电请求信息，并根据所述第一充电请求信息确定第一充电射频功率；根据所述第一充电射频功率启动预设的充电射频场，以供所述电子设备进行充电。通过以上方案，本申请将传统的触点接触通讯的方式，转换为NFC通讯控制的方式，使得电子设备与电源设备之间可以通过NFC通讯进行数据通讯，避免传统的触点接触通讯因触点金属老化或触点磨损造成数据通讯异常的情况发生，进而提升电子设备与电源设备之间的数据通讯效率，确保电子设备与电源设备之间充电数据的正常交互，从而保障电源设备能够实时根据电子设备的充电数据调整充电方式，进而提升充电效率，保障电子设备的正常使用。
进一步地，基于第一实施例，提出本申请NFC通讯控制方法的第二实施例，在该实施例中，所述根据所述第一充电射频功率启动预设的充电射频场，以供所述电子设备进行充电的步骤之后还包括：
步骤a，每隔第一预设时长基于NFC无线通讯获取所述电子设备的第二充电请求信息；
步骤b，根据所述第二充电请求信息确定第二充电射频功率；
步骤c，若所述第二充电射频功率与所述第一充电射频功率不一致，则根据所述第二充电射频功率对所述充电射频场进行功率调整。
电源设备在向电子设备进行充电的过程中，随着充电时间的增加，电子设备中的电量将持续增加。假设电子设备中的电量较多，则需要降低电子设备的充电功率，以避免由于充电过快导致电子设备中的电池受损或温度升高 影响电池寿命。若电子设备中的电量较少且当前电池适应充电状态后，则需要提升电子设备的充电功率，以加快充电效率。
由于电源设备和电子设备处于NFC无线通讯中，因此电源设备和电子设备之间存在实时的数据交互，在充电过程中也相互传输相应的充电交互数据。电子设备在检测到耳机自身的电量较多时，例如达到所需电量的80％时，为保障电子设备电池的持续正常运行，电子设备会降低所需的充电功率，采用涓流充电的方式进行小功率充电。TWS在检测到耳机自身的电量较少，且电池已经适应当前的充电状态，电子设备会提高所需的充电功率，采用快速充电的方式进行大功率充电。可以理解的是，这些功率调整数据将写入第二充电请求信息中。
由于电子设备的充电需求会随时间变化而变化，因此本实施例中，电源设备将每隔得一预设时长通过NFC无线通讯获取到电子设备的第二充电请求信息，并确定第二请求信息中的第二充电射频功率，所述确定过程与第一充电射频功率的过程一致。获取到第二充电射频功率之后，电源设备将比对第二充电射频功率和第一充电射频功率的数值大小。若第二充电射频功率和第一充电射频功率不一致，则电源设备需要根据第二充电射频功率对充电射频场进行功率调整，例如调整磁场强度，磁场方向等等。
电源设备通过与电子设备的NFC无线通讯交互，每隔第一预设时长获取电子设备的NFC无线通讯充电请求，从而调整自身的充电射频场功率，进而调整对电子设备所输出的充电功率。
更进一步地，所述根据所述第一充电射频功率启动预设的充电射频场，以供所述电子设备进行充电的步骤之后还包括：
步骤d，实时获取所述电子设备基于NFC无线通讯发送的功率变化值；
步骤e，若在第二预设时长内检测到所述功率变化值大于第一警戒值，则停止所述充电射频场，并输出警报指示音。
在进行充电的过程中，电源设备将实施检测获取电子设备基于NFC无线通讯发送的功率变化值，所述功率变化值指的是电子设备在充电过程中的相邻单位时间内实际充电功率的变化幅度。假设第二预设时长为5秒，若电子设备第1秒的实际充电功率为9W，第2秒的实际充电功率为10W，第3秒的实际充电功率为5W，第4秒的实际充电功率为11W，第5秒的实际充电功率为6W。 那么在5秒内电子设备的功率变化值为1W，5W，6W，5W。这证明在电子设备获取充电电量的过程中，充电功率存在一定的变化幅度，若变化幅度过大，则证明充电过程不稳定。这种情况通常是充电出现异常，容易造成安全隐患。因此需要对第二预设时长内检测功率变化值的变化幅度。本实施例设置了第一警戒值，若功率变化值大于第一警戒值，则证明当前充电出现异常，电源设备需要停止向电子设备进行充电，避免发生意外。例如第一警戒值为3W，而如上所述的功率变化值在第二预设时长(5秒)内存在功率变化值大于第一警戒值(3W)的情况，此时电源设备将停止充电射频场的功能，以断开电源设备与电子设备的充电连接，并发出警报指示音，以提示用户。
造成发生功率变化值大于第一警戒值的现象可能是电子设备和电源设备之间存在影响磁场感应的物件，若金属块；或者可能是电源设备以及电子设备中的充电芯片发生短路异常，导致充电过程的功率变化值过大，影响正常充电。
进一步地，基于第一实施例，提出本申请NFC通讯控制方法的第三实施例，在该实施例中，所述NFC通讯控制方法包括：
步骤f，获取当前的第一实时温度，并基于NFC无线通讯获取所述电子设备的第二实时温度；
步骤g，若检测到所述第一实时温度或第二实时温度大于第二警戒值，则关闭所述充电射频场，以停止向所述电子设备进行充电。
在本实施例中，电源设备或电子设备可能因为充电芯片发生异常导致二者无法实现正常的充电过程。例如电路短路，芯片烧坏等情况，这种异常情况可能会造成电源设备以及电子设备发生温度上升，因此需要对电源设备和电子设备进行实时温度检测。本实施例中，电源设备实时获取设备自身的第一实时温度，并通过NFC无线通讯实时获取电子设备的第二实时温度。
所述第二警戒值指的是实时充电温度的警戒参考值，若第一实时温度或第二实时温度大于第二警戒值，证明当前电源设备或电子设备的实时充电温度不正常，处于危险状态，具有造成当前电子设备和电源设备的电路因温度过高而发生爆炸的危险，此时电源设备将通过关闭充电射频场，以直接停止向所述电子设备充电。可以理解的是，NFC无线通讯可快速将二者的实时温 度进行数据交互，避免传统信息通讯方法响应不及时的情况发生。
