为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。
在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
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。
除了通过流量进行上网之外，当前电子设备还可以利用WiFi为用户提供上网功能。示例性的，如图1所示，以电子设备为手机进行展示。在使用WiFi功能进行上网的过程中，用户需要打开手机上的WiFi功能。如，用户可以通过设置应用的界面，如图1中的(a)所示的界面11进入WiFi功能的设置界面，如图1中的(b)所示的界面12。之后，用户可以对界面12中的用于控制手机WiFi功能打开/关闭的WiFi开关进行操作，以触发手机打开/关闭手机的WiFi功能。在手机接收到打开WiFi功能的操作后，手机可以进行周期性地扫描，以扫描周围可用的WiFi网络。在扫描到可用的WiFi网络后，手机可在如图1中的(b)所示的界面12的可用WiFi列表中显示手机扫描到的可用WiFi网络的标识，如WiFi网络的名称，如XXX1、XXX2等。之后，用户可在可用WiFi列表中选择需要手机连接的WiFi网络，如选中需要手机连接的WiFi网络的标识。在接收到用户选中可用WiFi列表中的某个WiFi网络的标识的操作后，手机可连接到用户选择的WiFi网络，以供用户上网。
其中，手机进行周期性扫描具体的可以为：手机的WiFi芯片周期性地对可用的WiFi信道进行扫描，如周期性地扫描5G频段中可用的WiFi信道，从而确定可用的WiFi网络，以通过可用WiFi列表将扫描到的可用WiFi网络的信息展示给用户，供用户选择。
但用户可能会遇到不明原因的扫描异常，如在WiFi芯片异常的情况下，会造成扫 描异常。其中，在扫描异常的情况下，用户是无法使用WiFi进行上网的。如在WiFi芯片异常的情况下，如图1中的(c)所示的界面13，手机显示的可用WiFi列表中不包括任何WiFi网络的信息，这导致用户无法选择需要手机连接的WiFi网络，从而导致无法使用WiFi进行上网。
在相关技术中，对WiFi芯片异常时用户无法使用WiFi进行上网，并未采取补救方案。换句话说，在WiFi芯片异常场景中，用户就没有办法使用WiFi进行上网，无法满足用户的上网需求。
为了解决上述问题，本申请实施例提供一种WiFi芯片的控制方法，在判断出当前场景为WiFi芯片异常的场景，也就是在因WiFi芯片异常导致扫描异常的场景下，控制WiFi芯片下电。通过精准识别WiFi芯片异常的场景并触发WiFi芯片下电使其自愈，以使得电子设备能正常通过WiFi接入网络，满足用户的上网需求，提高了用户的体验。

另外，需要说明的是，本申请实施例提供的WiFi芯片的控制方法，可以应用于由于电子设备的WiFi芯片异常导致的扫描异常的场景中。其中，WiFi芯片异常导致的扫描异常的场景可以是WiFi芯片扫描成功，但可用WiFi列表中不包括成功扫描到的WiFi网络的信息；也可以是WiFi芯片扫描失败，如，WiFi芯片接收到扫描指令，但是并未进行扫描，从而造成的扫描失败；亦或是WiFi功能异常，电子设备监测到用户在设置界面中手动操作WiFi开关的场景等。

以下结合图3来介绍电子设备实现WiFi芯片的自愈的具体流程。如图3所示，图3为本申请实施例提供一种WiFi芯片的控制方法流程示意图，该方法可以包括：S301-S302。
S301.获取WiFi芯片的标志位，标志位用于指示是否需要WiFi芯片下电。
为了保证WiFi芯片能够正常工作，在本申请一些实施例中，电子设备，如电子设备的处理器可以周期性对WiFi芯片进行监测，即执行S301，以确定WiFi芯片是否发生异常，从而保证用户使用WiFi时的上网体验。
在其他一些实施例中，电子设备，如电子设备的处理器可以在确定满足预定条件时，对WiFi芯片进行监测，即执行S301，以确定WiFi芯片是否发生异常。例如，该预定条件可以包括是否监听到灭屏广播。电子设备，如电子设备的处理器可以在监听到灭屏广播的情况下，对WiFi芯片进行监测，以确定WiFi芯片是否发生异常。其中，电子设备，如电子设备处理器可以周期性的监听是否有灭屏广播。其中，在电子设备需要熄灭屏幕(后续简称为熄屏)的情况下，处理器可以发送灭屏广播。电子设备熄屏可以是用户触发的，也可以是电子设备自动触发的，如电子设备在预定时长后未接收到用户对电子设备的操作，电子设备便会自动熄屏。
其中，监测WiFi芯片是否异常可以根据WiFi芯片的标志位确定。在本实施例中，WiFi芯片的标志位可以是一个用于指示是否需要对WiFi芯片下电的标志。该标志位也可以称为下电标志位，下电自愈标志位，或灭屏下电自愈标志位等。该标志位可以设置于WiFi芯片中，也可以不设置于WiFi芯片中，如设置于电子设备的其他器件，如处理器中。
示例性的，在获取到的WiFi芯片的标志位用于指示不需要对WiFi芯片下电的情 况下，表明WiFi芯片未发生异常，即WiFi芯片可以正常扫描，用户可以正常使用WiFi进行上网，此时可以重新执行S301。在获取到的WiFi芯片的标志位用于指示需要对WiFi芯片下电的情况下，表明WiFi芯片发生异常，如WiFi芯片可能无法正常扫描，用户无法正常使用WiFi进行上网，则可以执行下述S302。
S302.响应于标志位用于指示需要WiFi芯片下电，控制WiFi芯片下电。
在确定标志位用于指示需要WiFi芯片下电的情况下，电子设备，如电子设备的处理器可以控制WiFi芯片下电。所谓下电是指让WiFi芯片脱离电源，如停止对WiFi芯片进行供电。例如，电子设备，如电子设备的处理器在确定WiFi芯片的标志位用于指示需要WiFi芯片下电的情况下，可以向电子设备的电源管理模块发送下电控制指令，该下电控制指令用于指示停止为WiFi芯片供电。电子设备的电源管理模块接收到下电控制指令后，停止向WiFi芯片供电。
如S301的描述，S301可以周期性的执行。在S301周期性执行的情况下，在一些实施例中，电子设备，如电子设备的处理器可以在基于获取到的WiFi芯片的标志位确定需要对WiFi芯片下电的情况下，便控制WiFi芯片下电。在其他一些实施例中，在电子设备，如电子设备的处理器基于获取到的WiFi芯片的标志位确定需要对WiFi芯片下电后，电子设备，如电子设备的处理器可以监听是否有灭屏广播，并在监听到灭屏广播的情况下，再控制WiFi芯片下电。S301也可以在满足预定条件，如监听到灭屏广播的情况下执行。在S301在监听到灭屏广播的情况下才执行时，电子设备，如电子设备的处理器可以监听到灭屏广播后，执行S301，并在基于获取到的WiFi芯片的标志位确定需要对WiFi芯片下电的情况下，便控制WiFi芯片下电。
需要说明的是，以上实施例是以先监听是否有灭屏广播，后对WiFi芯片进行监测，或者先对WiFi芯片进行监测，再监听是否有灭屏广播为例进行介绍的，在其他一些实施例中，电子设备，如电子设备的处理器也可以同时对WiFi芯片及是否有灭屏广播进行监测，并在监听到灭屏广播且WiFi芯片的标志位用于指示需要WiFi芯片下电的情况下，控制WiFi芯片下电。本申请实施例在此对监听灭屏广播和对WiFi芯片进行监测的执行先后顺序不作具体限定。
采用本申请的技术方案，在WiFi芯片的标志位用来指示需要WiFi芯片下电的情况下，表明WiFi芯片可能存在异常，此时可以控制WiFi芯片下电，以此来恢复WiFi芯片的功能，使当前场景不再由于WiFi芯片异常而导致扫描异常，从而使得用户可以正常使用电子设备的WiFi功能上网，增加用户的体验感。另外，可以在电子设备灭屏的情况下，控制WiFi芯片下电，从而不影响用户的体验感。
在实际使用中，能够表明WiFi芯片异常的场景可能存在很多，下面以两个实施例进行展示。
在实施例一中，能够表明WiFi芯片异常的场景是：WiFi芯片的扫描结果为扫描成功，但是上报的扫描结果列表却为空，如上报给上层应用的扫描结果列表中可用的WiFi网络的数量为0。换句话说，用户在设置界面打开WiFi开关后，WiFi芯片能够正常进行扫描，且成功扫描到了WiFi网络，但设置界面中显示的可用WiFi列表中却不显示扫描到的WiFi网络的标识，从而导致用户无法选择需要电子设备接入的WiFi网络，导致无法使用WiFi上网。这种WiFi芯片异常场景用户通常无法感知。
在实施例二中，能够表明WiFi芯片异常的场景是：WiFi芯片进行扫描后，扫描结果为扫描失败，且扫描失败的原因是预设原因。这种场景下，用户也是无法使用WiFi上网的。且这种WiFi芯片异常场景用户通常也是无法感知的。
上述两种表明WiFi芯片异常的场景往往可以通过控制WiFi芯片下电而使得WiFi芯片自愈。那么在这两种场景中，可以通过设置WiFi芯片的标志位用于指示WiFi芯片需要下电，来控制WiFi芯片下电，以便恢复WiFi芯片的功能，确保用户可以正常使用WiFi上网。下面将对这两个实施例进行详细介绍。
实施例一
在WiFi芯片的扫描结果为扫描成功，但是上报的扫描结果列表却为空的场景中，电子设备，如电子设备的处理器可以基于WiFi芯片的信息来对WiFi芯片的标志位进行设置。如，在WiFi芯片的信息用于指示WiFi芯片异常的情况下，设置WiFi芯片的标志位为第一值，用于指示需要WiFi芯片下电。其中，具体过程可以如下所示：
在本申请的一些实施例中，电子设备，如电子设备的处理器可以基于WiFi芯片的信息判断是否满足第一条件来确定WiFi芯片是否异常，或者说确定当前场景是否为WiFi芯片异常场景。WiFi芯片的信息可以包括WiFi芯片的WiFi扫描结果，WiFi芯片的WiFi开关的状态信息，和WiFi芯片的扫描结果列表。
其中，WiFi芯片的扫描结果可以包括扫描成功和扫描失败。如，电子设备，如电子设备的处理器监听到WiFi扫描广播，则可确定扫描结果为扫描成功。电子设备，如电子设备的处理器未监听到WiFi扫描广播，则可确定扫描结果为扫描失败。WiFi芯片的开关可以是用于用户开启/关闭WiFi功能的控件，该控件可以包含在电子设备的设置应用中，也可以包含在电子设备的控制中心，当然还可以包含在其他应用中供用户开启/关闭电子设备的WiFi功能。WiFi开关的状态信息可以包括开启状态和关闭状态。扫描结果列表可以是用于向用户展示扫描到的可用WiFi网络的信息的列表。当前，向用户展示扫描到的可用WiFi网络的信息的方式也可以不是列表形式，而是其他形式，本实施例在此不做具体限制。
在一些示例中，第一条件可以包括WiFi扫描结果用于指示WiFi芯片扫描成功，WiFi开关的状态信息用于指示WiFi开关处于开启状态，和扫描结果列表为空。也就是说，电子设备，如电子设备的处理器可以获取WiFi芯片的信息，即获取WiFi芯片的WiFi扫描结果，WiFi芯片的WiFi开关的状态信息，和WiFi芯片的扫描结果列表。在WiFi扫描结果用于指示WiFi芯片扫描成功，WiFi开关的状态信息用于指示WiFi开关处于开启状态，且扫描结果列表为空的情况下，电子设备，如电子设备的处理器可以确定WiFi芯片的信息满足第一条件，即确定WiFi芯片的信息指示WiFi芯片异常，或者说确定当前场景为WiFi芯片异常场景。此时，电子设备，如电子设备的处理器可以设置WiFi芯片的标志位为第一值，用于指示需要WiFi芯片下电。
需要说明的是，上述WiFi扫描结果是否用于指示WiFi芯片扫描成功，WiFi开关的状态信息是否用于指示WiFi开关处于开启状态，和扫描结果列表是否为空的判断并没有先后的执行顺序。作为一种示例，如图4所示，基于第一条件，确定当前场景是否为WiFi芯片异常场景的具体流程如下：
电子设备，如电子设备的处理器可以先获取WiFi芯片的WiFi扫描结果，如电子 设备的处理器可以监听是否有WiFi扫描结果的广播(如，android.net.wifi.SCAN_RESULTS)。在没有监听到WiFi扫描结果的广播的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在监听到WiFi扫描结果的广播的情况下，电子设备，如电子设备的处理器可以获取WiFi开关的状态信息，以便进一步判断WiFi开关是否处于开启状态。在确定WiFi开关处于关闭状态的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在确定WiFi开关处于开启状态的情况下，继续判断WiFi芯片的扫描结果列表是否为空。在确定扫描结果列表不为空的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在确定扫描结果列表为空的情况下，表明当前场景为WiFi芯片异常场景，电子设备，如电子设备的处理器可以设置WiFi芯片的标志位为第一值，用于指示需要WiFi芯片下电。
在另一示例中，第一条件还可以包括电子设备当前所处位置的位置信息用于指示电子设备处于预设位置集合中。也就是说，电子设备，如电子设备的处理器除了根据上述提到的WiFi芯片的WiFi扫描结果，WiFi芯片的WiFi开关的状态信息，和WiFi芯片的扫描结果列表的之外，还需要基于电子设备当前所处位置的位置信息判断WiFi芯片是否异常，即基于这四个参数判断当前场景是否为WiFi芯片异常场景，从而确定是否需要控制WiFi芯片下电来自愈。也就是说，电子设备，如电子设备的处理器除了可以获取WiFi芯片的WiFi扫描结果，WiFi芯片的WiFi开关的状态信息，和WiFi芯片的扫描结果列表之外，还可以获取电子设备当前所处位置的位置信息。在WiFi扫描结果用于指示WiFi芯片扫描成功，WiFi开关的状态信息用于指示WiFi开关处于开启状态，扫描结果列表为空，且电子设备当前所处位置的位置信息用于指示电子设备处于预设位置集合中的情况下，电子设备，如电子设备的处理器可以确定WiFi芯片的信息满足第一条件，即可以确定WiFi芯片异常，或者说可以确定当前场景为WiFi芯片异常场景。此时，电子设备，如电子设备的处理器可以设置WiFi芯片的标志位为第一值，用于指示需要WiFi芯片下电。
其中，电子设备当前所处的位置信息作为判断条件是为了规避当用户带着电子设备去到一些不常去的陌生环境，如，这些陌生环境(如山区)中可能未部署WiFi网络，如若不进行该判断，可能误判当前场景为WiFi芯片异常场景。
类似的，上述WiFi扫描结果是否用于指示WiFi芯片扫描成功，WiFi开关的状态信息是否用于指示WiFi开关处于开启状态，扫描结果列表是否为空，以及当前所处位置的位置信息是否用于指示电子设备处于预设位置集合中的判断并没有先后的执行顺序。作为一种示例，结合图4，如图5所示，基于第一条件，确定当前场景是否为WiFi芯片异常场景的具体流程如下：
电子设备，如电子设备的处理器可以先获取WiFi芯片的WiFi扫描结果，如电子设备的处理器可以监听是否有WiFi扫描结果的广播(如，android.net.wifi.SCAN_RESULTS)。在没有监听到WiFi扫描结果的广播的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在监听到WiFi扫描结果的广播的情况下，电子设备，如电子设备的处理器可以获取WiFi开关的状态信息，以便进一步判断WiFi开关是否处于开启状态。在确定WiFi开关处于关闭状态的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在确定WiFi开关处于开启状态 的情况下，继续判断WiFi芯片的扫描结果列表是否为空。在确定扫描结果列表不为空的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在确定扫描结果列表为空的情况下，继续判断当前电子设备所处位置是否处于预设位置集合中。如，可以获取当前电子设备接入的小区的标识(简称当前小区标识，当前cell id)，判断当前cell id是否包含在常用cell id集合中，该常用cell id集合预先配置在电子设备中。在当前电子设备所处位置未处于预设位置集合中的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在当前电子设备所处位置处于预设位置集合中的情况下，电子设备，如电子设备的处理器可以设置WiFi芯片的标志位为第一值，用于指示需要WiFi芯片下电。
在本申请的又一些实施例中，电子设备，如电子设备的处理器可以基于WiFi芯片的信息，多次确定是否满足第一条件，即确定满足第一条件的次数是否大于第一阈值，以此来确定当前场景是否为WiFi芯片异常场景。在满足第一条件的次数大于第一阈值的情况下，可以认为WiFi芯片的信息用于指示WiFi芯片异常，或者说可以确定当前场景为WiFi芯片异常场景，基于此可以设置WiFi芯片的标志位为第一值。其中，WiFi芯片的信息以及第一条件的具体描述可以参照上述实施例对应内容的描述，在此不再赘述。此处，以第一条件包括：WiFi扫描结果用于指示WiFi芯片扫描成功，WiFi开关的状态信息用于指示WiFi开关处于开启状态，扫描结果列表为空，和电子设备当前所处位置的位置信息用于指示电子设备处于预设位置集合中为例，结合图6对该实施例进行举例说明。
如图6所示，电子设备，如电子设备的处理器可以获取WiFi芯片的WiFi扫描结果，如电子设备的处理器可以监听是否有WiFi扫描结果的广播。在没有监听到WiFi扫描结果的广播的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在监听到WiFi扫描结果的广播的情况下，电子设备，如电子设备的处理器可以获取WiFi开关的状态信息，以便进一步判断WiFi开关是否处于开启状态。在确定WiFi开关处于关闭状态的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在确定WiFi开关处于开启状态的情况下，继续判断扫描结果列表是否为空。在确定扫描结果列表不为空的情况下，清空扫描结果列表为空的累计次数，并重新执行监听是否有WiFi扫描结果的广播的操作。在确定扫描列表为空的情况下，继续判断当前电子设备所处位置是否处于预设位置集合中。在当前电子设备所处位置未处于预设位置集合中的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在当前电子设备所处位置处于预设位置集合中的情况下，对扫描结果列表为空的累计次数加一。之后，可以继续判断扫描结果列表为空的累计次数是否大于第一阈值，如扫描结果列表为空的累计次数是否大于5。在扫描结果列表为空的累计次数不大于第一阈值的情况下，可以重新执行监听是否有WiFi扫描结果的广播的操作。在扫描结果列表为空的累计次数大于第一阈值的情况下，表明满足第一条件的次数大于第一阈值，即可以确定WiFi芯片异常，或者说可以确定当前场景为WiFi芯片异常的场景，电子设备，如电子设备的处理器可以设置WiFi芯片的标志位为第一值，用于指示需要WiFi芯片下电。
需要说明的是，第一条件中的各参数判断并没有先后执行顺序的限制。在图6示例中先判断WiFi扫描结果，再判断WiFi开关状态，再判断扫描结果列表，最后判断 电子设备当前所处位置的位置信息，只是示例性的展示了一种执行顺序，在此不做唯一限定。
实施例二
在WiFi芯片进行扫描后，扫描结果为扫描失败，且扫描失败的原因是预设原因场景中，电子设备，如电子设备的处理器可以基于WiFi芯片的信息来对WiFi芯片的标志位进行设置。如，在WiFi芯片的信息用于指示WiFi芯片异常的情况下，设置WiFi芯片的标志位为第一值，用于指示需要WiFi芯片下电。其中，具体过程可以如下所示：
在一些实施例中，电子设备，如电子设备的处理器可以基于WiFi芯片的WiFi扫描结果来确定WiFi芯片是否异常，或者说确定当前场景是否为WiFi芯片异常场景。例如，在WiFi芯片的WiFi扫描结果为WiFi芯片扫描失败，且扫描失败的原因为预设原因的情况下，确定WiFi芯片异常。例如，电子设备，如电子设备的处理器可以在确定WiFi扫描结果为扫描失败的情况下，继续判断造成扫描失败的原因，从而根据扫描失败的原因确定是否需要通过控制WiFi芯片下电来使其自愈。之所以判断扫描失败的原因是因为造成WiFi芯片扫描失败的原因多种多样，而在扫描失败的原因为预设原因的情况下，才能够通过触发WiFi芯片下电让其自愈。作为一种示例，预设原因可以是1,22,95,100。其中，预设原因1对应的是无权操作(Operation not permitted，EPERM)。预设原因22对应的是参数无效(Invalid argument,EINVAL)。预设原因95对应的是传输端点不支持操作(Operation not supported on transport endpoint，EOPNOTSUPP)。预设原因100对应的是网络已宕(Network is down，ENETDOWN)。所以，在本申请实施例中，可以在确定WiFi芯片的WiFi扫描结果用于指示WiFi芯片扫描失败，且扫描失败的原因为预设原因的情况下，设置WiFi芯片的标志位为第一值，用于指示WiFi芯片异常，以便可以通过控制WiFi芯片下电来使其自愈。
作为一种示例，如图7所示，基于WiFi芯片的WiFi扫描结果，确定当前场景是否为WiFi芯片异常场景，或者说确定当前场景是否为WiFi芯片扫描失败场景的具体流程如下：
电子设备，如电子设备的处理器可以确定WiFi芯片的WiFi扫描结果是否为扫描失败。如，电子设备的处理器可以判断在预设时间内是否监听到WiFi扫描结果的广播，若在预设时间内未监听到扫描结果的广播，则可确定扫描失败。在确定WiFi芯片的WiFi扫描结果为扫描失败的情况下，确定扫描失败的原因(如，Handle wifi condsc an fail)。接着，判断扫描失败的原因是否为预设原因。在扫描失败的原因不为预设原因的情况下，可以重新判断WiFi芯片的WiFi扫描结果是否为扫描失败。在扫描失败的原因为预设原因的情况下，可以确定WiFi芯片异常，或者说可以确定当前场景为WiFi芯片异常场景，电子设备，如电子设备的处理器可以设置WiFi芯片的标志位为第一值，用于指示需要WiFi芯片下电。
在另一些实施例中，电子设备，如电子设备的处理器可以基于WiFi芯片的WiFi扫描结果，多次确定WiFi扫描结果是否为扫描失败且失败原因是否为预设原因，即确定WiFi扫描结果为扫描失败且失败原因为预设原因的次数是否大于第二阈值，以此认为WiFi芯片的信息用于指示WiFi芯片异常。基于此，可以设置WiFi芯片的标志位为第一值。其中，WiFi芯片的WiFi扫描结果的具体描述可以参照上述实施例对应内 容的描述，在此不再赘述。
结合图7，如图8所示，对该实施例进行举例说明。如图8所示，电子设备，如电子设备的处理器可以确定WiFi芯片的WiFi扫描结果是否为扫描失败，如在预设时长内未监听到WiFi扫描结果的广播，则认为扫描失败。在确定WiFi芯片的WiFi扫描结果为扫描失败的情况下，确定扫描失败的原因。接着，判断扫描失败的原因是否为预设原因。在扫描失败的原因不为预设原因的情况下，清空扫描失败的原因累计次数，并重新执行确定WiFi芯片的WiFi扫描结果是否为扫描失败的操作。在扫描失败的原因为预设原因的情况下，对扫描失败的原因累计次数加一，继续判断扫描失败的原因累计次数是否大于第二阈值，如扫描失败的原因累计次数是否大于3。在扫描失败的原因累计次数小于第二阈值的情况下，可以重新执行确定WiFi芯片的WiFi扫描结果是否为扫描失败的操作。在扫描失败的原因累计次数大于第二阈值的情况下，表明扫描失败且失败原因为预设原因的次数大于第二阈值，即可以确定WiFi芯片异常，或者说可以确定当前场景为WiFi芯片异常的场景，电子设备，如电子设备的处理器可以设置WiFi芯片的标志位为第一值，用于指示需要WiFi芯片下电。
需要说明的是，在扫描失败的原因累计次数等于第二阈值的情况下，可以认为WiFi芯片异常，即执行设置标志位为第一值的操作，也可以重新执行确定WiFi芯片的WiFi扫描结果是否为扫描失败的操作，本申请实施例在此对原因累计次数等于第二阈值时，电子设备执行的操作不做具体限制，可以根据实际应用场景的需要进行设置。
其中，可以理解的是，通过上述实施例一和实施例二，电子设备，如电子设备的处理器可以在满足条件的情况下，将WiFi芯片的标志位设置为第一值，如可以将第一值设置为true，以便指示需要WiFi芯片下电。那么，通过执行图3所示的实施例，便可在WiFi芯片的标志位被设置为第一值的情况下，达到控制WiFi芯片下电使其自愈的目的。另外，电子设备，如电子设备的处理器可以在控制WiFi芯片下电之后，便控制其上电。或者，还可以是在控制WiFi芯片下电之后的预设时间后控制其上电。本申请实施例在此对控制WiFi芯片下电后，重新控制WiFi芯片上电的时机及触发条件不作具体限定。另外，继续结合图3，在控制WiFi芯片下电之后，电子设备，如电子设备的处理器可以设置标志位为第二值，如设置第二值为flase，用于指示不需要WiFi芯片下电。
需要说明的是，在实施例一和实施例二中，是以在满足相应条件后通过设置标志位，以便能够基于标志位控制WiFi芯片下电为例进行说明的。在其他一些实施例中，也可以是在确定满足相应的条件后，便控制WiFi芯片下电。例如，可以在确定满足上述第一条件或满足上述第一条件的次数大于第一阈值的情况下，电子设备，如电子设备的处理器控制WiFi芯片下电。又例如，可以在确定WiFi扫描结果为扫描失败，且失败的原因为预设原因的情况下，控制WiFi芯片下电。
实施例三
上述实施例中的两种WiFi芯片异常场景，用户不一定有感知。实际使用中，用户有可能能够感知到异常。如用户在之前使用手机连接过家里的WiFi网络，但是用户当前在家中且WiFi开关处于开启状态手机却无法接入家里的WiFi网络。在这种情况下，用户一般会通过手动操作WiFi开关，来尝试恢复WiFi功能。但用户通过手动操作 WiFi开关可能并不能恢复WiFi功能。因此本申请实施例中，在用户手动操作WiFi开关的情况下，可判断当前场景是否为WiFi芯片异常场景，并在当前场景为WiFi芯片异常场景的情况下，控制WiFi芯片下电来实现自愈。
以下，结合图9来介绍电子设备实现WiFi芯片的自愈的具体流程。如图9所示，图9位本申请实施例提供另一种WiFi芯片的控制方法流程示意图，该方法包括S901-S902。
S901.获取WiFi芯片的信息；WiFi芯片的信息包括WiFi芯片的WiFi开关的变化信息，WiFi开关的状态信息，缓存的WiFi芯片的扫描结果列表和缓存的WiFi芯片的扫描结果列表的时间戳。
在用户连接WiFi网络的过程中，往往会存在无法连接的情况，用户可能会手动在设置界面上对WiFi开关进行操作，从而尝试能够正常连接WiFi网络。为了能保证WiFi芯片的正常工作，在本申请一些实施例中，电子设备，如电子设备的处理器可以获取WiFi芯片的信息，即执行S901,以确定WiFi芯片是否发生异常，或者说判断当前场景是否为WiFi芯片异常场景，从而保证用户使用WiFi时的上网体验。
其中，WiFi芯片的信息可以包括WiFi芯片的WiFi开关的变化信息，WiFi开关的状态信息，缓存的WiFi芯片的扫描结果列表和缓存的WiFi芯片的扫描结果列表的时间戳。其中，WiFi芯片开关的变化信息是指电子设备设置界面的WiFi开关的状态是否发生变化，如WiFi开关由开启状态变成关闭状态，或者WiFi开关由关闭状态变成开启状态。WiFi芯片的WiFi开关的状态信息是指在WiFi开关处于开启状态或关闭状态。缓存的WiFi芯片的扫描结果列表是指在电子设备的缓存中存储的WiFi扫描结果列表，也就是上一次WiFi芯片扫描到的WiFi网络的扫描结果列表。上述时间戳可以是指在电子设备的缓存中存储扫描结果列表的时间或者说，扫描结果列表的缓存时间。如，在扫描结果列表包括多个扫描到的WiFi网络的信息的情况下，该扫描结果列表的缓存时间，即上述时间戳可以为扫描到第一个WiFi网络的时间。例如，扫描结果列表中包括两个WiFi网络的信息，分别为WiFi1和WiFi2。扫描到WiFi1的时间为12：02，扫描到WiFi2的时间为12：03，则扫描结果列表的缓存时间为12：02，也就是说时间戳为12：02。
S902.响应于WiFi芯片的信息用于指示WiFi芯片异常，控制WiFi芯片下电。
在上述S901中获取到WiFi芯片的信息用于指示WiFi芯片异常的情况下，电子设备，如电子设备的处理器可以控制WiFi芯片下电。
在本申请的一些实施例中，电子设备，如电子设备的处理器可以基于WiFi芯片的信息确定WiFi芯片是否异常，或者说确定当前场景是否为WiFi芯片异常场景。在WiFi开关的变化信息用于指示WiFi开关的状态发生变化，WiFi开关的状态信息用于指示WiFi开关处于关闭状态，扫描结果列表不为空和时间戳大于预设阈值的情况下，可以认为WiFi芯片的信息用于指示WiFi芯片异常。也就是说，电子设备，如电子设备的处理器可以获取WiFi芯片的WiFi开关的变化信息，WiFi开关的状态信息，缓存的WiFi芯片的扫描结果列表和缓存的WiFi芯片的扫描结果列表的时间戳。在WiFi开关的状态发生变化，WiFi开关的状态信息用于指示WiFi开关处于关闭状态，扫描结果列表不为空和时间戳大于预设阈值的情况下，电子设备，如电子设备的处理器可 以确定WiFi芯片的信息用于指示所述WiFi芯片异常。基于此，电子设备，如电子设备的处理器可以控制WiFi芯片下电。
需要说明的是，WiFi芯片的WiFi开关的变化信息，WiFi开关的状态信息，缓存的WiFi芯片的扫描结果列表和缓存的WiFi芯片的扫描结果列表的时间戳的判断并没有先后顺序的限制。作为一种示例，如图10所示，基于WiFi芯片的信息，确定当前场景为WiFi芯片异常场景的具体流程可以如下：
电子设备，如电子设备的处理器可以先监听WiFi开关的变化信息，如电子设备处理器可以监听是否有用于指示WiFi开关状态发生变化的广播。在未监听用于指示WiFi开关状态发生变化的广播的情况下，重新执行监听WiFi开关状态的变化信息的操作。在监听到用于指示WiFi开关状态发生变化的广播的情况下，电子设备，如电子设备的处理器可以获取WiFi开关的状态信息，以便进一步判断WiFi开关是否处于关闭状态。在确定WiFi开关处于开启状态的情况下，重新执行监听WiFi开关状态的变化信息的操作。在确定WiFi开关的状态处于关闭状态的情况下，电子设备，如电子设备的处理器可以获取缓存的WiFi芯片的扫描结果列表,进而判断缓存的WiFi芯片的扫描结果列表是否为空。在缓存的WiFi芯片的扫描结果列表为空的情况下，重新执行监听WiFi开关状态的变化信息的操作。在获取到的缓存的WiFi芯片的扫描结果列表不为空的情况下，进而判断缓存的WiFi芯片的扫描结果列表的时间戳是否大于预设阈值，如判断时间戳是否大于20s。在上述时间戳大于预设阈值的情况下，电子设备，如电子设备的处理器控制WiFi芯片下电。
需要说明的是，在上述时间戳等于预设阈值的情况下，电子设备，如电子设备的处理器可以认为WiFi芯片异常，即执行控制WiFi芯片下电的操作，也可以重新执行监听WiFi开关状态的变化信息的操作，本申请实施例在此对时间戳等于预设阈值时，电子设备执行的操作不做具体限制，可以根据实际应用场景的需要进行设置。
其中，上述预设阈值可以根据经验值设置的。具体的，预设阈值可以设置为大于扫描周期的一个值，在此不作唯一限定。
需要说明的是，上述的实施例中以电子设备中的处理器为例对本申请方案的执行过程进行了说明，执行本申请方案过程的也可以是电子设备中的其他器件，在此不作具体限制。
综上，在上述三种出现WiFi芯片异常的场景中，可以通过控制WiFi芯片下电，实现WiFi芯片在一定时间内自愈，从而保证用户WiFi功能的正常使用，提高用户的上网体验感。
