一种设备组网方法、电子设备及系统
本申请要求于2019年12月11日提交国家知识产权局、申请号为201911268282.2、发明名称为“一种设备组网方法、电子设备及系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种设备组网方法、电子设备及系统。
背景技术
随着智能家居技术的发展，一个用户或家庭中往往具备多个能够互相通信的电子设备。各类电子设备一般具有各自的设备特点，例如，手机的便携性更好，电视屏幕的显示效果更好，而音箱的音质效果更好。为了充分发挥不同电子设备的设备特点，多个电子设备之间可以进行组网，从而将多个电子设备互联进行协同工作。
以星型拓扑结构的组网过程举例，用户家中的各个电子设备进行组网时可将预设的某一电子设备(例如电视、路由器或手机等)确定为主设备(master)。进而，除主设备之外的每个电子设备可作为从设备(slave)与主设备建立通信连接(例如蓝牙连接、Wi-Fi连接等)，形成星型拓扑结构的局域网。这样，主设备作为中心节点可用于管理和控制该局域网中的各个从设备，完成相应的工作任务。
但是，一旦网络中的主设备出现掉线、故障或断电等异常情况时，主设备无法继续管理和控制网络中的各个从设备，导致整个网络无法正常工作，用户的使用体验也随之降低。
发明内容
本申请提供一种设备组网方法、电子设备及系统，可延长组网后网络的持续时间以及网络的稳定性，提高用户的使用体验。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供一种设备组网方法，包括：第一设备在通信系统中将第二设备确定为主设备，其中，第二设备为第一类型设备，第一设备为第二类型设备，第一类型设备为通过外接电源供电的设备(例如路由器)，第二类型设备为使用电池供电的设备(例如手机)；进而，第一设备可作为从设备与第二设备建立通信连接；当第二设备出现异常(即当前的主设备出现异常)时，第一设备可在上述通信系统中将第三设备确定为新的主设备，第三设备为上述第二类型设备；进而，第一设备可作为从设备与第三设备(即新的主设备)建立通信连接。
可以看出，在选举通信系统中的主设备进行设备组网时，可优先将第一类型设备确定为通信系统中的主设备组建星型结构的网络，以保证网络的持续时间以及网络的稳定性；当第一类型设备出现异常时，可将主设备从第一类型设备迁移为第二类型设备，从而动态地调整网络中的主设备，以保证网络的持续时间以及网络的稳定性达到 最优。
在一种可能的实现方式中，第一设备在的通信系统中将第二设备确定为主设备，包括：第一设备查询该通信系统中是否包含第一类型设备；若包含第一类型设备，则第一设备在第一类型设备中将第二设备确定为主设备。其中，通信系统中的第一类型设备可以为一个或多个，或者，通信系统也可以不包含第一类型设备。
在一种可能的实现方式中，第一设备中存储有设备信息列表，该设备信息列表中记录有通信系统中各个设备的设备信息，例如，各个设备的设备类型；此时，第一设备查询上述通信系统中是否包含第一类型设备，包括：第一设备根据其设备信息列表中各个设备的设备类型，可查询到当前通信系统内是否包含第一类型设备。
在一种可能的实现方式中，第一设备在第一类型设备中将第二设备确定为主设备，包括：若第一类型设备中仅包括第二设备，说明当前通信系统中仅包括一个第一类型设备，则第一设备可将第二设备确定为主设备；若第一类型设备中包括多个设备，则第一设备可根据预设的主设备决策算法，从多个第一类型设备中选出第二设备作为主设备。
也就是说，在通信系统内进行设备组网时，当通信系统中包含第一类型的电子设备时，可优先选择将第一类型的电子设备作为网络中的主设备。一方面，第一类型的电子设备作为主设备时发生断电等异常情况的几率较低，可保证组网后整个网络的稳定性。另一方面，第一类型的电子设备作为主设备时可减轻网络中第二类型的电子设备的功耗开销，从而延续组网后整个网络的持续时间。
在一种可能的实现方式中，当第二设备出现异常时，第一设备在上述通信系统中将第三设备确定为新的主设备，包括：当第二设备出现异常时，第一设备查询当前的通信系统中是否包含第一类型设备；若不包含第一类型设备，则第一设备在第二类型设备中将第三设备确定为新的主设备。其中，通信系统中的第二类型设备可以为一个或多个，或者，通信系统也可以不包含第二类型设备。
在一种可能的实现方式中，第一设备在第二类型设备中将第三设备确定为新的主设备，包括：第一设备根据设备信息列表中记录的第二类型设备的设备信息，将第三设备确定为新的主设备。
示例性的，第三设备可以为第二类型设备中电量大于电量阈值的设备；和/或，第三设备可以为第二类型设备中唤醒时间大于时间阈值的设备；和/或，第三设备可以为第二类型设备中唤醒频率大于频率阈值的设备。
也就是说，在通信系统内进行设备组网时，当通信系统中不包含第一类型的电子设备时，可在第二类型的电子设备中根据各个第二类型的电子设备的唤醒时长、电量等参数优先选择有利于组网时功耗开销较小且网络持续时间较长的电子设备作为主设备，从而保证组网后整个网络的稳定性。
在一种可能的实现方式中，在第一设备作为从设备与第二设备建立通信连接之后，还包括：第一设备定期向第二设备发送第一设备的设备信息，并从第二设备中获取该通信系统中最新的设备信息列表。这样，通信网络中各个从设备中存储的设备信息列表与当前主设备中存储的设备信息列表同步，均处于最新的状态。一旦主设备发生异常，各个从设备可根据最新的设备信息列表重新选举主设备进行组网。
示例性的，由于第一设备为第二类型的电子设备，那么，可设置第一设备向第二设备发送设备信息的周期与第一设备的心跳周期相同。这样，可减少第一设备从休眠状态被唤醒至唤醒状态的唤醒次数，降低了第一设备的功耗。
在一种可能的实现方式中，在第一设备作为从设备与第二设备建立通信连接之后，还包括：若第一设备接收到通信系统内其他从设备发送的主设备异常消息，则第一设备可确定第二设备(即当前的主设备)出现异常；或者，若第一设备检测到与第二设备之间的通信连接断开(例如第一设备检测到与第二设备之间的通信连接超时)，则第一设备可确定第二设备(即当前的主设备)出现异常，从而触发通信网络中的各个电子设备开始重新选择新的主设备进行组网。
在一种可能的实现方式中，在第一设备作为从设备与第三设备建立通信连接之后，还包括：若第一设备接收到第三设备发送的主设备迁移消息，说明第三设备此时已经不适合作为主设备继续运行，则第一设备可在当前的通信系统中重新确定新的主设备进行组网。
在一种可能的实现方式中，在第一设备作为从设备与第二设备建立通信连接之后，还包括：当第二设备(即当前的主设备)出现异常时，第一设备也可以将自身确定为当前通信系统中新的主设备，例如，当第一设备为当前通信系统中电量最高的第二类型设备时，可将自身确定为当前通信系统中新的主设备；进而，第一设备可作为主设备与通信系统中的其他设备建立通信连接，组成星型拓扑结构的网络。
在一种可能的实现方式中，在第一设备将自身确定为通信系统中新的主设备之后，还包括：第一设备检测自身的运行状态是否满足预设的主设备迁移条件；若满足预设的主设备迁移条件，说明第一设备此时已经不适合作为主设备继续运行，则第一设备可向通信系统中的其他设备发送主设备迁移消息，从而触发通信网络中的各个电子设备开始重新选择新的主设备进行组网。
示例性的，上述主设备迁移条件包括：主设备的电量小于电量阈值；和/或，主设备的唤醒时间小于时间阈值；和/或，主设备的唤醒频率小于频率阈值。
可以看出，当第二类型设备作为主设备在通信网络中运行后，该第二类型设备可实时检测自身的运行状态是否适合作为主设备继续工作，如果不再适合作为主设备继续工作，则可触发通信网络中的电子设备重新选择最优的电子设备作为新的主设备进行组网和运行，从而动态地调整网络中的主设备，使得网络的稳定性以及网络的持续时间达到最优。
第二方面，本申请提供一种电子设备，包括：一个或多个处理器、一个或多个存储器、通信模块以及一个或多个计算机程序；其中，处理器与触摸屏、通信模块以及存储器均耦合，上述一个或多个计算机程序被存储在存储器中，当电子设备运行时，该处理器执行该存储器存储的一个或多个计算机程序，以使电子设备执行上述任一项所述的设备组网方法。
第三方面，本申请提供一种通信系统，包括一个或多个第一类型设备以及一个或多个第二类型设备，第一类型设备为通过外接电源供电的设备，第二类型设备为使用电池供电的设备；当第一设备为第二类型设备时，第一设备可执行上述任一项所述的设备组网方法。

具体实施方式
下面将结合附图对本实施例的实施方式进行详细描述。
本申请实施例提供的一种设备组网方法，可应用于图1所示的通信系统100中，通信系统100中可包括N(N为大于1的整数)个电子设备。
其中，上述电子设备具体可以为第一类型的电子设备，也可以为第二类型的电子设备。
第一类型的电子设备是指通过外接电源使用交流电向自身供电的电子设备(也可称为长电设备或第一类型设备)。例如，第一类型的电子设备可以包括电视、路由器、台式计算机、音箱等。这类电子设备在工作时可通过插头、数据线等使用外接电源获取电力公司提供的电能，因此，第一类型的电子设备接入外接电源后可一直处于待机状态，用户对这类电子设备的功耗一般不做特殊要求。
第二类型的电子设备是指使用电池向自身供电的电子设备(也可称为电池设备或第二类型设备)。例如，第二类型的电子设备可以包括手机、平板电脑、笔记本电脑等。这类电子设备在工作时需要使用电池向设备自身供电。以手机为第二类型的电子设备举例，手机息屏后可进入待机状态(也可称为休眠状态)，当手机需要与其他电子设备交互时，需要先唤醒手机的处理器(例如CPU)及相关通信模块(例如Wi-Fi芯片)。当处理器或通信模块的唤醒次数较多时，会增加手机的功耗从而缩短待机时间。因此，用户在使用第二类型的电子设备时一般希望这类电子设备的功耗越小越好。
在本申请实施例中，上述通信系统100中可以包括X个第一类型的电子设备101和Y个第二类型的电子设备102，X+Y＝N。电子设备101和电子设备102可按照一定的拓扑结构和组网算法组建网络，使得通信系统100内的各个电子设备之间可以互相 通信。
以星型拓扑结构举例，在星型拓扑结构中，网络中的各节点可通过点到点的方式连接到一个主设备(master，也可称为中心节点或中央节点)上，与主设备相连的节点可称为从设备，主设备用于集中控制和管理网络中的各个从设备。在本申请实施例中，上述通信系统100中的电子设备101或电子设备102都可以作为主设备进行组网，当通信系统100中的主设备确定后，通信系统100中的其他电子设备可作为从设备与主设备建立通信连接，从而完成通信系统100的组网过程。
在本申请实施例中，通信系统100中的各个电子设备内可存储并维护一份设备信息列表。该设备信息列表中可以包括通信系统100内每个电子设备的设备信息。例如，该设备信息可以包括设备名称、设备类型(例如第一类型或第二类型)、电量信息、唤醒时长或唤醒频率等一项或多项反映该设备状态的信息。其中，对于第二类型的电子设备102，电量信息是指电子设备102剩余的电池容量或电量百分比；对于第一类型的电子设备101，由于用户对这类电子设备的电量通常不做要求，因此可在设备信息列表中将电子设备101的电量信息设置为100％，或者，电子设备101的设备信息列表中可以不设置电量信息这一参数。上述唤醒时长是指一定时间内电子设备中的处理器被唤醒后的工作时长。上述唤醒频率是指一定时间内电子设备中处理器被唤醒的次数。
示例性的，电子设备A存储的设备信息列表如表1所示，电子设备A通过该设备信息列表可查询到通信系统100中其他电子设备(例如音箱1、路由器或手机1)的具体名称、类型、电量以及唤醒时长等设备状态。也就是说，每个电子设备通过自身存储的设备信息列表可以获知通信系统100中其他电子设备最新的设备状态。
表1
设备名称 设备类型 电量信息 唤醒时长(最近24小时) ……
音箱1 第一类型 100％ 3小时10分钟 ……
路由器 第一类型 100％ 24小时 ……
手机1 第二类型 67％ 5小时46分钟 ……
需要说明的是，上述表1中也可以包括电子设备A自身的设备信息。另外，上述表1中所示的设备信息仅为举例说明，可以理解的是，该设备信息还可以包括设备型号、设备的入网时间、IP(internet protocol，互联网协议)地址、MAC(media access control，媒体访问控制)地址、设备提供的服务、自定义的业务信息等，本领域技术人员可根据实际经验或实际应用场景对此进行设置，本申请实施例对此不做任何限制。
那么，上述通信系统100中的各个电子设备在组网时，每个电子设备可根据自身存储的设备信息列表获取到通信系统100中各个电子设备最新的设备状态，进而，该电子设备可根据通信系统100中各个电子设备最新的设备状态，确定出当前通信系统100中的主设备具体为哪一个电子设备。
仍以电子设备A举例，电子设备A查询表1所示的设备信息列表后，可确定通信系统100中是否包含第一类型的电子设备101。如果包含第一类型的电子设备101，则电子设备A可优先将第一类型的电子设备101(例如路由器)确定为通信系统100中的主设备。
例如，当第一类型的电子设备101有多个时，电子设备A可将入网时间最早的电子设备101确定为本次组网的主设备。又例如，当第一类型的电子设备101有多个时，电子设备A可按照预设的优先级顺序将优先级最高的电子设备101确定为本次组网的主设备。
通常，作为主设备的电子设备在网络中的负载一般较高，而当第一类型的电子设备101为通信系统100中的主设备时，由于电子设备101可使用外接电源向自身供电，因此电子设备101作为主设备在高负载状态下运行时的稳定性较强，主设备出现断电等异常情况的几率较低，设备组网后网络的持续时间较长。
相应的，如果通信系统100中不包含第一类型的电子设备101，则电子设备A可根据上述设备信息列表中第二类型的电子设备102的设备信息，从多个电子设备102中确定一个主设备。
例如，电子设备A可根据表1中不同电子设备102的电量信息，将电量大于预设值或电量最高的电子设备102确定为本次组网的主设备。也就是说，当没有第一类型的电子设备101时，通信系统100中的电子设备在组网时可将电量较高的第二类型的电子设备102确定为主设备，减少组网后主设备因电量较低而出现异常的情况，从而保证组网后网络的稳定性以及网络的持续时间。
又例如，电子设备A可根据表1中不同电子设备102的唤醒时长，将唤醒时长大于预设值或唤醒时长最长的电子设备102确定为本次组网的主设备。也就是说，当没有第一类型的电子设备101时，通信系统100中的电子设备在组网时可将唤醒时长较长的第二类型的电子设备102确定为主设备。由于电子设备102在唤醒状态下作为主设备工作时不需要再额外唤醒处理器及相关通信模块增加功耗，因此，选择唤醒时长较长的电子设备102为主设备可降低组网时的功耗开销，从而保证组网后网络的稳定性以及网络的持续时间。
当然，电子设备A还可以结合各个电子设备102的电量信息、唤醒时长或其他设备信息(例如唤醒频率、当前的唤醒状态等)，选择一个第二类型的电子设备102作为主设备开始组网，本申请实施例对此不做任何限制。
除了电子设备A之外，通信系统100中的其他电子设备均可按照上述方法，根据设备信息列表确定出本次组网时通信系统100内的主设备。这样，确定出的主设备可与其他电子设备(即从设备)建立通信连接(例如Wi-Fi连接或蓝牙连接等)，完成本次组网过程。
组网成功后，通信系统100中的主设备可开始正常控制并管理网络中的各个从设备。如果检测到当前主设备的运行状态满足预设的主设备迁移条件，例如，主设备的电量较低或者主设备进入长期休眠状态，说明当前作为主设备的电子设备不再适合作为主设备继续运行。此时，主设备可通知通信系统100中的各个从设备重新按照上述方法确定出新的主设备进行组网，从而保证重新组网后网络的稳定性以及网络的持续时间。
也就是说，本申请实施例提供的设备组网方法还可以根据主设备的运行状态动态调整网络中的主设备，从而实时的选择通信系统100中最优的电子设备作为主设备进行组网和运行，提高网络的稳定性以及网络的持续时间。
示例性的，上述通信系统100中的电子设备具体可以是手机、平板电脑、桌面型、膝上型、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、手持计算机、上网本、个人数字助理(personal digital assistant，PDA)、可穿戴电子设备、车载设备、虚拟现实设备等，本申请实施例对此不做任何限制。
以手机为上述电子设备举例，图2示出了手机的结构示意图。
手机可以包括处理器110，外部存储器接口120，内部存储器121，通用串行总线(universal serial bus，USB)接口130，充电管理模块140，电源管理模块141，电池142，天线1，天线2，移动通信模块150，无线通信模块160，音频模块170，扬声器170A，受话器170B，麦克风170C，耳机接口170D，传感器模块180，摄像头193以及显示屏194等。

以下将结合附图详细阐述本申请实施例提供的一种设备组网方法。
以用户家中的各个电子设备组成上述通信系统100举例，用户家中的各个电子设备可通过家中的Wi-Fi网络进行组网。示例性的，电子设备1加入家中的Wi-Fi网络后，可通过DNS(domain name system，域名系统)组播的方式向Wi-Fi网络中的其他电子设备发送自身的设备信息。并且，Wi-Fi网络中的电子设备接收到新加入的电子设备1发来的设备信息后，也可向电子设备1回复自身的设备信息。这样，电子设备1加入Wi-Fi网络时可获取到已加入该Wi-Fi网络的每个电子设备发来的自身的设备信息，形成表2所示的设备信息列表。该设备信息列表中记录了Wi-Fi网络中每个电子设备的设备信息，用于指示每个电子设备最新的设备状态。
表2
Figure PCTCN2020133591-appb-000001
如表2所示，新加入的电子设备1得到的设备信息列表中包含Wi-Fi网络中各个电子设备的设备信息。其中，该设备信息具体可以包括设备的设备名称、设备类型、电量信息、唤醒时长以及唤醒频率等。当然，上述设备信息还可以包括设备的入网时间、当前的唤醒状态、设备型号、IP地址、MAC地址、设备提供的服务(例如语音、视频、拍照等)、自定义的业务参数(例如最近一次的唤醒时间)等能够反映设备状态的参数。
与表2所示的设备信息列表类似的，上述Wi-Fi网络中的每个电子设备中均维护有一份设备信息列表，进而，每个电子设备可基于自身存储的设备信息列表确定当前Wi-Fi网络中的主设备，从而与主设备建立通信连接进行组网。
仍以电子设备1举例，如图3所示，电子设备1基于上述设备信息列表确定Wi-Fi网络中的主设备进行组网的方法可包括下述步骤300-307。
步骤300、电子设备1判断Wi-Fi网络中是否包含第一类型的电子设备。
步骤301、当Wi-Fi网络中包含第一类型的电子设备时，电子设备1将第一类型的电子设备A确定为Wi-Fi网络中的主设备。
具体的，电子设备1在确定当前Wi-Fi网络中的主设备时，可先查询自身存储的设备信息列表中是否记录有第一类型的电子设备。如果记录有第一类型的电子设备，说明当前的Wi-Fi网络中已接入了第一类型的电子设备。由于第一类型的电子设备工作时使用外接电源供电，发生断电等异常情况的几率较低，因此，电子设备1可在第一类型的电子设备中确定一个为当前Wi-Fi网络中的主设备。
示例性的，如果当前的Wi-Fi网络中只有一个第一类型的电子设备，例如，电子设备A(电子设备A也可以为电子设备1自身)，则电子设备1可将这唯一的一个第一类型的电子设备A确定为当前Wi-Fi网络中的主设备。
或者，如果当前的Wi-Fi网络中包含多个第一类型的电子设备(这多个第一类型的电子设备中也可以包括电子设备1)，则电子设备1可按照预设的主设备决策算法，在多个第一类型的电子设备中选择一个作为当前Wi-Fi网络中的主设备。
例如，表2所示的设备信息列表中可以记录每个电子设备接入Wi-Fi网络的入网时间。此时，上述主设备决策算法可以为：入网时间最早的第一类型的电子设备为主设备。那么，电子设备1可根据设备信息列表中各个第一类型的电子设备的入网时间，将入网时间最早的第一类型的电子设备A确定为当前Wi-Fi网络中的主设备。
又例如，上述主设备决策算法还可以为：将特定类型的电子设备优选为主设备。示例性的，可预先设置不同的第一类型设备(即第一类型的电子设备)之间的优先级顺序，例如，电视的优先级大于路由器的优先级，路由器的优先级大于智能音箱的优先级。那么，电子设备1可将设备信息列表中优先级最高的第一类型设备(例如电子设备A)确定为当前Wi-Fi网络中的主设备。
当然，上述主设备决策算法还可以为raft选举算法等其他决策算法，本领域技术人员可根据实际应用场景或实际经验设置上述第一类型设备的主设备决策算法，本申请实施例对此不做任何限制。
另外，除了上述电子设备1之外，上述Wi-Fi网络中的其他电子设备中均维护有对应的设备信息列表。因此，当Wi-Fi网络中包含第一类型的电子设备时，Wi-Fi网络 中的其他电子设备均可按照相同的主设备决策算法将第一类型的电子设备A确定为当前Wi-Fi网络中的主设备。
或者，Wi-Fi网络中的各个电子设备可按照不同的主设备决策算法投票选举当前Wi-Fi网络中的主设备。例如，电子设备1可基于其存储的设备信息列表，按照主设备决策算法1将第一类型的电子设备A确定为主设备，并向Wi-Fi网络中的其他设备广播该决策结果1。同样，电子设备2可基于其存储的设备信息列表，按照主设备决策算法2将第一类型的电子设备C确定为主设备，并向Wi-Fi网络中的其他设备广播该决策结果2。这样，Wi-Fi网络中的每个电子设备可通过投票选举的方式，将所有决策结果中票数最多的第一类型的电子设备(例如电子设备A)确定为当前Wi-Fi网络中的主设备。
在一些实施例中，可以设置由Wi-Fi网络中的各个第一类型的电子设备参加上述投票选举过程。也就是说，当Wi-Fi网络中包含多个第一类型的电子设备时，可由这多个第一类型的电子设备互相投票选举出当前Wi-Fi网络中的主设备。此时，Wi-Fi网络中第二类型的电子设备无需参加上述投票选举过程，从而可降低第二类型的电子设备的功耗开销。
可以看出，在进行设备组网时，当待组网的多个设备中包含第一类型的电子设备时，可优先选择将第一类型的电子设备作为网络中的主设备。一方面，第一类型的电子设备作为主设备时发生断电等异常情况的几率较低，可保证组网后整个网络的稳定性。另一方面，第一类型的电子设备作为主设备时可减轻网络中第二类型的电子设备的功耗开销，从而延续组网后整个网络的持续时间。
当然，如果当前的Wi-Fi网络中不包含第一类型的电子设备，则电子设备1以及Wi-Fi网络中的其他电子设备可按照下述步骤305中的方法，在第二类型的电子设备中确定当前Wi-Fi网络中的主设备。
步骤302、电子设备1与电子设备A建立通信连接。
当电子设备1将第一类型的电子设备A确定为Wi-Fi网络中的主设备后，如图4所示，电子设备1可作为从设备与主设备(即电子设备A)建立通信连接。例如，该通信连接可以是L3层的网络连接。
其中，L3层的网络连接具体可以是TCP(transmission control protocol，传输控制协议)连接或基于UDP(user datagram protocol，用户数据报协议)的网络连接，例如基于UDP的CoAP(constrained application protocol，受限应用程序协议)连接，本申请实施例对此不做任何限制。
除了电子设备1之外，仍如图4所示，Wi-Fi网络中的其他电子设备也可按照上述步骤301中的方法将电子设备A确定为Wi-Fi网络中的主设备，并与电子设备A建立通信连接，这样，Wi-Fi网络中的电子设备A作为主设备与其他各个电子设备之间组建形成了星型拓扑结构的网络。
在一些实施例中，Wi-Fi网络中的电子设备A在执行上述步骤301时，也可以确定出自身为当前Wi-Fi网络中的主设备。那么，电子设备A确定出自己为主设备后也可以向Wi-Fi网络中的其他电子设备广播主设备更新的消息，该消息中可以携带电子设备A的标识。其他电子设备接收到该消息后可执行步骤302与电子设备A建立通信 连接，完成星型拓扑结构的组网过程。
步骤303、电子设备1定期向电子设备A发送自身的设备信息，并从电子设备A中获取最新的设备信息列表。
当电子设备1等各个从设备与电子设备A(即主设备)建立了通信连接，形成星型拓扑结构的组网后，电子设备A可作为中心节点接收Wi-Fi网络中各个从设备定期发送的设备信息，进而更新设备信息列表中对应设备的设备信息，使得电子设备A存储的设备信息列表中的各个设备信息处于最新的状态。并且，Wi-Fi网络中的各个从设备还可以从电子设备A中获取最新的设备信息列表，使得Wi-Fi网络中的每个设备均可获知其他设备最新的设备状态。
示例性的，当电子设备1为第一类型的电子设备时，电子设备1可启动预设的定时器T1。当定时器T1超时时，电子设备1可作为从设备向当前的主设备(即电子设备A)发送自身最新的设备信息。电子设备A接收到电子设备1发来的设备信息后，可更新其设备信息列表中对应的电子设备1的设备信息，使得电子设备A中存储的设备信息列表处于最新的状态。
并且，电子设备A接收到电子设备1发来的设备信息后，还可以将最新的设备信息列表发送给电子设备1，使得电子设备1通过该设备信息列表可获知Wi-Fi网络内其他电子设备最新的设备状态。
相应的，当电子设备1为第二类型的电子设备时，电子设备1可启动预设的定时器T2。当定时器T2超时时，电子设备1可作为从设备向当前的主设备(即电子设备A)发送自身最新的设备信息。同样，电子设备A可更新其设备信息列表中对应的电子设备1的设备信息。并且，电子设备A可将最新的设备信息列表发送给电子设备1，使得电子设备1中存储的设备信息列表与电子设备A中存储的设备信息列表同步，均处于最新的状态。
不同的是，当电子设备1为第二类型的电子设备时，电子设备1在休眠状态下与电子设备A交互时需要消耗额外的功耗唤醒电子设备1的处理器，造成电子设备1的功耗增加。因此，可设置电子设备1启动的定时器T2的周期与自身的设备唤醒周期同步。也就是说，可以在电子设备1处于唤醒状态时触发电子设备1向电子设备A发送自身最新的设备信息，并从电子设备A获取最新的设备信息列表。
例如，由于第二类型的电子设备(例如手机、平板电脑)会定期向PUSH消息服务器发送心跳报文。那么，可设置定时器T2的定时时长与电子设备1发送心跳报文的周期同步。这样，电子设备1每次被唤醒向PUSH消息服务器发送心跳报文的同时，可向电子设备A发送自身最新的设备信息，从而减少了电子设备1从休眠状态被唤醒至唤醒状态的唤醒次数，降低了电子设备1的功耗。
其中，电子设备处于唤醒状态可以是指电子设备中处理器被唤醒工作的状态，相应的，电子设备处于休眠状态可以是指电子设备中处理器处于休眠或低功耗的状态。示例性的，电子设备中可预先设置相应的标志位用于指示处理器的工作状态。例如，当该标志位为01时，说明电子设备的处理器处于工作状态，当该标志位为00时，说明电子设备的处理器处于休眠状态。那么，电子设备通过统计上述标志位的持续时间，可确定出电子设备处于唤醒状态或休眠状态的时长或频率。
除了电子设备1之外，Wi-Fi网络中的其他从设备也可以按照上述方法定期向电子设备A(即主设备)发送自身的设备信息，并从电子设备A中获取最新的设备信息列表，使得整个Wi-Fi网络中每个从设备存储的设备信息列表与电子设备A(即主设备)中存储的设备信息列表同步，均处于最新的状态。
步骤304、当电子设备1检测到与电子设备A之间的连接断开后，在Wi-Fi网络中广播主设备异常消息。
电子设备1将电子设备A作为主设备，与电子设备A建立通信连接后，如图5所示，如果电子设备1检测到与电子设备A之间的通信连接断开，例如，电子设备1与电子设备A之间的通信连接超时，或者，电子设备1向电子设备A连续N次发送设备信息时均发送失败，则说明此时电子设备A可能出现了掉线、故障或断电等异常情况，导致电子设备1与电子设备A之间的连接断开。那么，为了保证Wi-Fi网络中的各个电子设备能够继续组网运行，电子设备1可向Wi-Fi网络中的其他电子设备广播主设备异常消息，告知其他电子设备当前的主设备(即电子设备A)发生异常，以触发Wi-Fi网络中的各个电子设备开始重新选择新的主设备进行组网。
示例性的，电子设备1在广播主设备异常消息时，还可以在主设备异常消息中携带电子设备1最新的设备信息。接收到该主设备异常消息的电子设备也可在Wi-Fi网络中广播自身最新的设备信息。这样，当主设备(即电子设备A)发生异常后，Wi-Fi网络中的每个电子设备均可以获取到其他设备最新的设备信息，从而得到一份最新的设备信息列表。后续，Wi-Fi网络中的每个电子设备可基于该最新的设备信息列表重新选择新的主设备进行组网。
步骤304中是以电子设备1检测到与电子设备A连接超时举例说明的，可以理解的是，当Wi-Fi网络中的其他从设备检测到与电子设备A连接超时后，也可以按照步骤304的方法在Wi-Fi网络中广播主设备异常消息，触发Wi-Fi网络中的各个电子设备开始重新选择新的主设备进行组网。
仍以电子设备1举例，当电子设备1开始重新选择新的主设备进行组网时，可查询当前存储的最新的设备信息列表中是否记录有第一类型的电子设备，即当前的Wi-Fi网络中是否包含第一类型的电子设备。如果包含第一类型的电子设备，则电子设备1可继续按照上述步骤301所述的方法确定新的主设备。相应的，如果不包含第一类型的电子设备，则电子设备1可执行下述步骤305确定新的主设备。
另外，如果电子设备A(即主设备)检测到与某一从设备之间的通信连接断开，说明该从设备可能出现了掉线、故障或断电等异常情况。那么，电子设备A可在维护的设备信息列表中将该从设备的相关设备信息删除，使得电子设备A中存储的设备信息列表处于最新的状态。
步骤305、当Wi-Fi网络中不包含第一类型的电子设备时，电子设备1将第二类型的电子设备B确定为Wi-Fi网络中的主设备。
仍以电子设备1举例，如果电子设备1检测到与电子设备A之间的连接断开，或接收到其他电子设备广播的主设备异常消息，说明此时需要在Wi-Fi网络中重新选择新的主设备进行组网。那么，电子设备1可在存储的最新的设备信息列表中查询是否记录有第一类型的电子设备。
如果设备信息列表中没有记录第一类型的电子设备，说明当前的Wi-Fi网络中不包含第一类型的电子设备，则电子设备1可根据设备信息列表中第二类型的电子设备的设备信息，将第二类型的电子设备B确定为当前Wi-Fi网络中的主设备。
示例性的，如果当前的Wi-Fi网络中只有一个第二类型的电子设备，例如，电子设备B(电子设备B也可以为电子设备1自身)，则电子设备1可将这唯一的一个第一类型的电子设备B确定为当前Wi-Fi网络中的主设备。
或者，如果当前的Wi-Fi网络中包含多个第二类型的电子设备(即第二类型设备)，则电子设备1可根据设备信息列表中这些第二类型设备的电量信息、唤醒时间或唤醒频率等参数，选择一个第二类型设备作为当前Wi-Fi网络中的主设备。
例如，电子设备1可将设备信息列表中电量最高的第二类型设备(例如电子设备B)确定为当前Wi-Fi网络中的主设备。也就是说，当Wi-Fi网络中不包含第一类型的电子设备时，可将电量较高的第二类型设备确定为主设备进行组网，减少组网后主设备因电量较低而出现异常的情况，从而保证组网后网络的稳定性以及网络的持续时间。
又例如，电子设备1可将设备信息列表中唤醒时间最长的第二类型设备(例如电子设备B)确定为当前Wi-Fi网络中的主设备。当电子设备B的唤醒时间越长时，电子设备B作为主设备工作时需要额外唤醒其处理器开始工作的次数越少。因此，当Wi-Fi网络中不包含第一类型的电子设备时，选择唤醒时间越长的第二类型设备作为主设备进行组网，可降低组网时的功耗开销，从而保证组网后网络的稳定性以及网络的持续时间。
又例如，电子设备1可将设备信息列表中唤醒频率最高的第二类型设备(例如电子设备B)确定为当前Wi-Fi网络中的主设备。类似的，当电子设备B的唤醒频率越高时，电子设备B使用越频繁，电子设备B中处理器处于工作状态的时间越长，此时电子设备B作为主设备工作时从休眠状态被唤醒的次数越少。因此，当Wi-Fi网络中不包含第一类型的电子设备时，选择唤醒频率越高的第二类型设备作为主设备进行组网，可降低组网时的功耗开销，从而保证组网后网络的稳定性以及网络的持续时间。
又或者，电子设备1可结合第二类型设备的唤醒时间和唤醒频率选择最优的第二类型设备作为当前Wi-Fi网络中的主设备。例如，电子设备1可在唤醒时间大于第一预设值(例如大于5小时)的多个第二类型设备中，选择唤醒频率最高的第二类型设备作为当前Wi-Fi网络中的主设备。
又或者，电子设备1存储的设备信息列表中还可以包括当前各个第二类型设备的唤醒状态，即当前第二类型的电子设备处于唤醒状态或休眠状态。那么，电子设备1在多个第二类型设备中确定主设备时，还可以结合当前第二类型设备的唤醒状态选择主设备。例如，如果唤醒时间大于第一预设值，且唤醒频率大于第二预设值的第二类型设备有多个，则电子设备1可优先将当前处于唤醒状态的第二类型设备作为当前Wi-Fi网络中的主设备。这样，处于唤醒状态的第二类型设备切换为主设备工作时无需额外唤醒其处理器增加设备功耗。
又或者，电子设备1可结合第二类型设备的电量信息、唤醒时间以及唤醒频率等多项参数选择最优的第二类型设备作为当前Wi-Fi网络中的主设备。例如，当唤醒时间大于第一预设值，且唤醒频率大于第二预设值的第二类型设备有多个时，电子设备 1可在这多个第二类型设备中选择电量最高的第二类型设备作为当前Wi-Fi网络中的主设备。这样，既可以降低因唤醒该第二类型的主设备而带来的功耗开销，还可以减少组网后主设备因电量较低而出现异常的情况，从而保证组网后网络的稳定性以及网络的持续时间。
在另一些实施例中，电子设备1还可以选择多个第二类型设备轮流作为Wi-Fi网络中的主设备进行工作。例如，如果电子设备1在其设备信息列表中查询到当前Wi-Fi网络中包含3个第二类型设备，则电子设备1可确定由这3个第二类型设备以一定的工作周期(例如2小时)轮流作为Wi-Fi网络中的主设备进行工作。又例如，电子设备1可根据第二类型设备的电量信息和唤醒时间确定出电量较高且唤醒时间较长的2个第二类型设备，进而，电子设备1可确定由这2个第二类型设备以一定的工作周期轮流作为Wi-Fi网络中的主设备进行工作。
另外，除了上述电子设备1之外，上述Wi-Fi网络中的其他电子设备中均存储有与电子设备1同步的设备信息列表。因此，当Wi-Fi网络中原有的主设备(即电子设备A)发生异常时，Wi-Fi网络中的其他电子设备均可按照上述步骤301或305中所述的方法重新确定当前Wi-Fi网络中的主设备。
可以看出，当待组网的多个电子设备中不包含第一类型的电子设备时，电子设备可在第二类型的电子设备中根据各个第二类型的电子设备的唤醒时长、电量等参数优先选择有利于组网时功耗开销较小且网络持续时间较长的电子设备作为主设备，从而保证组网后整个网络的稳定性。
步骤306、电子设备1与电子设备B建立通信连接。
与步骤302类似的，当电子设备1将第二类型的电子设备B确定为Wi-Fi网络中的主设备后，如图6所示，电子设备1可作为从设备与主设备(即电子设备B)建立通信连接，并断开与原主设备(即电子设备A)之间的通信连接。
除了电子设备1之外，Wi-Fi网络中的其他电子设备也可按照上述步骤305中的方法将电子设备B确定为Wi-Fi网络中新的主设备，并与新的主设备建立通信连接，这样，仍如图6所示，Wi-Fi网络中的电子设备B作为新的主设备与其他各个电子设备之间再次组建形成了星型拓扑结构的网络。对于用户而言，Wi-Fi网络中原有的主设备发生异常时，Wi-Fi网络中的其他设备可感知到该异常情况并自动确定出新的主设备重新进行组网，用户仍然可以正常使用该Wi-Fi网络对完成对相关电子设备的控制功能，从而提高了用户的使用体验。
当电子设备1等各个从设备与新的主设备(即电子设备B)建立了通信连接，形成星型拓扑结构的组网后，与电子设备A作为主设备的工作过程类似的，此时电子设备B可作为中心节点接收Wi-Fi网络中各个从设备定期发送的设备信息，进而更新设备信息列表中对应设备的设备信息，使得电子设备B存储的设备信息列表中的各个设备信息处于最新的状态。并且，Wi-Fi网络中的各个从设备还可以从电子设备B中获取最新的设备信息列表，使得Wi-Fi网络中每个设备存储的设备信息列表与电子设备B中存储的设备信息列表同步，均处于最新的状态。
步骤307、当电子设备B的运行状态满足预设的主设备迁移条件时，电子设备1重新执行上述步骤301或305。
当第二类型的电子设备B作为主设备开始工作后，电子设备B可实时检测自身的运行状态是否满足预设的主设备迁移条件。如图7所示，当满足预设的主设备迁移条件时，说明电子设备B已经不适合作为此时Wi-Fi网络中的主设备继续工作。那么，电子设备B可向Wi-Fi网络中的各个从设备广播主设备迁移消息，触发接收到该主设备迁移消息的从设备(例如电子设备1)通过执行上述步骤301或305开始重新选择新的主设备进行组网。
示例性的，上述主设备迁移条件可以包括：主设备的电量低于预设电量，或主设备的电量低于任意一个从设备的电量。
例如，电子设备B作为主设备开始工作后，可以实时获取自身的电量信息。当自身的电量低于预设电量(例如50％)时，此时电子设备B继续作为主设备工作容易出现电量耗尽等影响网络稳定性的情况，因此，电子设备B可向Wi-Fi网络中的各个从设备广播主设备迁移消息，触发从设备重新选择新的主设备进行组网。
又例如，电子设备B作为主设备开始工作后，可以实时获取自身的电量信息，并在设备信息列表中比较自身的电量信息与其他电子设备的电量信息。如果自身的电量低于Wi-Fi网络中各个从设备的电量，或者，自身的电量低于大部分从设备(例如80％的从设备)的电量，同样，电子设备B此时继续作为主设备工作容易出现电量耗尽等影响网络稳定性的情况，因此，电子设备B可向Wi-Fi网络中的各个从设备广播主设备迁移消息，触发从设备重新选择新的主设备进行组网。
示例性的，上述主设备迁移条件可以包括：主设备的唤醒时长小于预设的唤醒时长，或主设备的唤醒频率小于预设的唤醒频率。
例如，电子设备B作为主设备开始工作后，可以根据处理器的工作时长统计电子设备B处于唤醒状态的唤醒时长。当检测到电子设备B的唤醒时长小于预设的唤醒时长时，说明电子设备B中处理器被唤醒的时间较短，这会导致电子设备B作为主设备工作时需要额外唤醒处理器增加电子设备B的功耗，因此，电子设备B可向Wi-Fi网络中的各个从设备广播主设备迁移消息，触发从设备重新选择新的主设备进行组网。或者，电子设备B也可以根据处理器的休眠时长统计电子设备B处于休眠状态的休眠时长。如果电子设备B的休眠时长大于预设的休眠时长，说明电子设备B已进入休眠状态，若电子设备B继续作为主设备工作需要额外唤醒处理器增加电子设备B的功耗，因此，电子设备B可向Wi-Fi网络中的各个从设备广播主设备迁移消息，触发从设备重新选择新的主设备进行组网。
又例如，电子设备B作为主设备开始工作后，还可以根据处理器的工作频率统计出电子设备B的唤醒频率。如果电子设备B的唤醒频率小于预设的唤醒频率，说明电子设备B中处理器被唤醒的次数较少，若电子设备B继续作为主设备工作需要额外唤醒处理器增加电子设备B的功耗，因此，电子设备B可向Wi-Fi网络中的各个从设备广播主设备迁移消息，触发从设备重新选择新的主设备进行组网。
可以理解的是，上述主设备迁移条件还可以包括其他影响电子设备B作为主设备继续工作的条件，本申请实施例对此不做任何限制。例如，该主设备迁移条件还可以为主设备的工作时长大于预设时长。那么，如果检测到电子设备B作为主设备时工作的工作时长大于预设时长时，为了避免主设备的工作任务为电子设备B带来过高的负 载，电子设备B可向Wi-Fi网络中的各个从设备广播主设备迁移消息，触发从设备重新选择新的主设备进行组网。
另外，当上述Wi-Fi网络中接入了新的电子设备时，也可触发Wi-Fi网络中的各个电子设备通过执行上述步骤301或305开始重新选择新的主设备进行组网，本申请实施例对此不做任何限制。
可以看出，本申请实施例提供的设备组网方法可以根据当前主设备的运行状态确定该主设备是否适合继续作为主设备工作。如果当前作为主设备的电子设备不再适合作为主设备继续工作，则可触发Wi-Fi网络中的电子设备重新选择Wi-Fi网络中最优的电子设备作为新的主设备进行组网和运行，从而动态地调整网络中的主设备，使得网络的稳定性以及网络的持续时间达到最优。
需要说明的是，上述实施例中是以电子设备在Wi-Fi网络中进行设备组网举例说明的，可以理解的是，电子设备还可以在蓝牙、近距离无线通信技术(near field communication，NFC)、基于互联网协议的语音通话(voice over Internet protocol，VoIP)、以太网、全球移动通讯系统(global system for mobile communications，GSM)、通用分组无线服务(general packet radio service，GPRS)、码分多址接入(code division multiple access，CDMA)、宽带码分多址(wideband code division multiple access，WCDMA)，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进(long term evolution，LTE)等通信网络中使用上述组网方法组建星型拓扑结构的网络，本申请实施例对此不做任何限制。
