随着电子设备的迅速发展，电子设备可以通过预设定位方式进行位置定位，该预设定位方式可以包括全球定位系统(global positioning system，GPS)、基站定位、无线热点(wifi AP)定位、北斗卫星定位等。以GPS定位为例，当电子设备丢失且进入离线状态后，电子设备向周边的在线设备发送蓝牙广播。当周边的在线设备接收到蓝牙广播后，通过GPS信号定位得到位置信息，并将位置信息上报给服务器，查找设备可以根据在线设备的位置信息确定电子设备的大概范围，使用户能够更快速准确的找到电子设备。
但是，若在线设备接收到多个蓝牙广播，需要频繁地启用位置上报服务，增加了在线设备功耗；这样，在电子设备查找的过程中，使得查找丢失设备的效率会较低，无法达到较好的查找效果。

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清楚、完整地描述。
为了使本技术领域的人员更好地理解本发明方案，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分的实施例，而不是全部的实施例。基于本发明中的实施例，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，都应当属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚 地列出的或对于这些过程、方法、系统、产品或设备固有的其它步骤或单元。
现有的设备查找方法中，假设第一电子设备为丢失设备，第二电子设备为丢失设备周边的在线设备。每当第二电子设备接收到第一设备发送的蓝牙广播时，第二电子设备就会GPS定位，网络定位，唤醒无线接入点(access point，AP)，上传数据，启动应用程序等。示例性的，一次GPS定位需要0.278mAH，一次网络定位需要0.4-0.7mAH，即，一次网络定位需要(0.4+0.7)/2＝0.55mAH，一次唤醒AP需要0.05mAH，一次上传数据需要0.02mAH，一次启动应用程序需要0.09mAH。假设每两次定位需要一次网络定位，则每次第二电子设备定位上报位置信息时需要消耗功耗为：0.278+0.55/2+0.05+0.02+0.09＝0.713mAH。又由于第二电子设备的功耗有限，假设第二电子设备每天协助上报定位信息的功耗损耗需要小于3mAH，因此，第二电子设备一天仅能上报定位信息的次数为0.713mAH/3mAH＝4次。这样，在第一电子设备查找的过程中，有限的定位信息上报次数使得查找丢失设备的效率会较低，无法达到较好的查找效果。
为了解决上述技术问题，在本申请实施例中，第二电子设备的第一应用程序获取至少一个位置信息。在第一应用程序获取至少一个位置信息之后，第二电子设备扫描第一电子设备发送的第一蓝牙广播。第二电子设备根据第一蓝牙广播获取第一位置信息，该第一位置信息为至少一个位置信息中的至少一个。第二电子设备将第一位置信息上报给服务器。可见，第二电子设备可以利用第二电子设备上的其他应用程序获取的位置信息，而非，第二电子设备扫描到蓝牙广播时，无需频繁通过调用第二应用程序获取的位置信息，这样，可以有效减少功耗，同时可以实现多次上报位置信息的效果，使得查找丢失设备的效率较高。
为方便理解本发明，下面先对本发明的设备查找方法的一种场景应用进行描述。如图1所示，图1为本发明的设备查找系统的结构示意图。
参见图1，该设备查找系统至少包括两个电子设备。该电子设备可以指支持蓝牙的电子设备。以两个电子设备为例，这两个电子设备分别可以为第一电子设备100和第二电子设备200。其中，第一电子设备100和第二电子设备200均可以包括蓝牙模块，该蓝牙模块可以集成在电子设备上(即一体式)，也可以是可插拔在电子设备上。第一电子设备100和第二电子设备200可以通过蓝牙连接。其中，两个设备通过蓝牙连接指的是该两个设备之间建立起蓝牙链路，该两个设备可以通过该蓝牙链路向对方发送信号以及接收对方发送的信号，该信号称为蓝牙信号。
其中，所述第一电子设备可以为丢失设备，第一电子设备的数量可以为至少一个。第一电子设备具有联网能力，所述联网能力是指通过WIFI或蜂窝网络与互联网连接；本申请实施例中，第一电子设备的状态为用户关闭了联网功能(关闭WIFI和蜂窝网络)时，使得第一电子设备处于断网状态，第二电子设备无法与服务器进行通信。因此，当第一电子设备处于断网状态时，第一电子设备无法通过自身的定位模块向服务器上报自身的位置信息。
其中，所述第二电子设备可以是丢失设备周边的任一设备，所述第二电子设备的数量可以为至少一个，如第二电子设备201、第二电子设备202、第二电子设备200。所述第二电子设备具备协助定位能力，当第二电子设备的用户开通了协助定位功能， 第二电子设备具有获取电子设备当前的位置信息，位置信息可以为例如经纬度信息；该定位过程可以通过上述GPS定位、基站定位、无线热点(wifi AP)定位、北斗卫星定位等融合定位实现。第二电子设备具有联网能力，所述联网能力是指通过WIFI或蜂窝网络与互联网连接，当第二电子设备的用户开启联网功能(打开WIFI或蜂窝网络)时，使得第二电子设备处于联网状态，第二电子设备可以与服务器进行通信。
上述第二电子设备可以作为好心人设备，上报第二电子设备的位置信息至服务器，帮助丢失设备定位所处的大概范围，以便于快速查找到丢失设备。具体为，当第一电子设备处于断网状态时，第一电子设备可以通过蓝牙连接向第二电子设备发送蓝牙广播，该蓝牙广播的内容可以包括第一设备持有的公钥P派生的公钥Pi。第二电子设备接收到第一电子设备发送的蓝牙广播后，获取蓝牙广播的内容中的公钥Pi，并采用集成加密方案(elliptic curve integrate encrypt scheme，ECIES)算法加密第二电子设备的定位信息。第二电子设备将定位信息的密文上传至服务器400。服务器400可以保存电子设备的相关信息和状态信息，可以提供电子设备信息管理及设备找回服务。
其中，第一电子设备100可以在所述服务器400上注册账号，并且，注册账号为与第一电子设备的国际移动设备身份码(International Mobile Equipment Identity，IMEI)或移动终端识别码(Mobile Equipment Identify，MEID)唯一绑定的序列。这样，第一电子设备和注册账号就绑定在一起，用户可以同时设定使用该注册账号的密码，成为该注册账号的合法使用者，使得用户通过所述注册账号登录所述服务器。所述第一电子设备的注册账号可以为终端设备系统账号。在另一些实施例中，所述第一电子设备的注册账号可以通过下载对应的应用程序后，在应用程序注册对应的账号获得；因此，第二电子设备与第一电子设备可以是不同终端厂商生产的终端设备，第二电子设备与第一电子设备安装有可与服务器交互的应用程序便可以实现本申请中的实施方案。
可选的，第一电子设备100可以为定位器、追踪器、手机、可穿戴设备如智能手表、平板电脑或个人数字助理(personal digital assistant，PDA)等支持蓝牙的电子设备。可选的，第一电子设备100和第二电子设备200均可以为手机、可穿戴设备如智能手表、平板电脑或PDA等支持蓝牙的电子设备。可选的，第一电子设备100和第二电子设备200可以为同一种电子设备，比如第一电子设备100和第二电子设备200均为手机；第一电子设备100和第二电子设备200也可以为不同种电子设备，比如第一电子设备100为手机、第二电子设备200为智能手表；或者，第一电子设备100为定位器/追踪器，第二电子设备200可以为手机。
在一些可行的实施方式中，提供的设备查找系统还包括第三电子设备300，用户可以在第三电子设备300上登录第一电子设备100的注册账号，通过第一电子设备100的注册账号与所述服务器400进行交互。第三电子设备300可以为电脑，手机、可穿戴设备如智能手表、平板电脑等。所述第三电子设备为电脑时，用户可以通过登录服务器的服务网址(例如门户系统Portal)登录用户账户；所述第三电子设备为手机等移动设备时，用户可以通过登录应用程序(例如查找我的设备)登录用户账户。当用户在第三电子设备上登录第一电子设备的账号后，可以远程控制第一电子设备执行相应的功能；示例性的，用户可以点击“定位设备”获得第一电子设备的当前位置；或者，用户可以点击“预设铃声”使第一电子设备的响铃；或者，用户可以点击“丢失模块”设 置第一电子设备的模式为丢失模式；或者，用户可以点击“删除数据”将第一电子设备的相关数据删除。
在一种具体可实现方式中，第一电子设备与第三电子设备预先配对，产生一对椭圆曲线上的公钥P和私钥d。第一电子设备持有公钥P，第三电子设备持有私钥d和公钥P。在具体应用中，可以应用于第一电子设备为定位器或追踪器的场景中。
在另一种具体可实现方式中，第一电子设备生成一对椭圆曲线上的公钥P和私钥d。在信任环境下，第一电子设备将公钥P和私钥d同步到第三电子设备上，第三电子设备与第一电子设备采用同一账号。在具体应用中，可以应用于第一电子设备为手机的场景中。
为便于理解，下面将对本申请实施例提供的电子设备的结构进行示例说明。

本申请实施例的设备查找方法可适用于一个或多个电子设备的定位场景中。为便于描述，下面仅以一个电子设备定位另一个电子设备为例进行说明。可理解的，该定位场景可以用于定位至少一个第一电子设备；第二电子设备也可以同时定位多个其他电子设备。
图4a是本申请实施例提供的设备查找方法的流程示意图。参见图4a，该方法可以包括：
第一个阶段，第二电子设备预先获取多个位置信息。
用户在使用第二电子设备上的第一应用程序时，第二电子设备可以为第一应用程序开启“位置信息访问权限”。具体地，以第一应用程序是相机为例，如图5a-图5d所示，用户操作第二电子设备的显示界面上的设置图标，第二电子设备的界面由图5a所示的界面跳转至图5b所示的界面，如相机设置界面201。用户可以选择第二电子设备的相机设置界面201中的“权限”功能，第二电子设备的界面由图5b所示的相机设置界面201跳转至图5c所示的界面，如位置信息权限界面202。用户选择位置信息权限界面202中的“始终允许”或“仅使用期间允许”功能。
在完成上述工作之后，用户对第二电子设备的第一应用程序操作，响应于用户对第一应用程序的操作，第二电子设备启动第一应用程序。在第一应用程序在运行期间，第二电子设备获取第一应用程序获取到的至少一个位置信息。沿用上述示例，用户操作相机，第二电子设备执行图3中所示的①②③。具体如下：在用户选择位置信息权限界面202中的“仅使用期间允许”功能下，①用户操作图5d所示的界面上的相机，该相机启动运行。此时，②该相机调用应用框架层的定位模块获取第二电子设备的位置信息。③在定位模块获取到第二电子设备的位置信息之后，应用框架层的记录模块记录定位模块获取的位置信息。此时，第二电子设备的记录模块记录该位置信息并将该位置信息存储在数据库中。
当然，第一应用程序也可以为网购类应用程序、外卖类应用程序、打车类应用程序、天气预报类应用程序，广告类应用程序或任何可以获取到终端当前位置的应用程序等中的一个或多个。当用户启动这些应用程序时，第二电子设备执行如上所述的操作，以获取在上述应用程序使用期间第二电子设备的位置信息。
其中，该定位模块可以包括全球定位系统(Global Positioning System，GPS)模块、 网络定位模块或融合定位模块等。该位置信息可以包括如表1所示的定位时间、定位经纬度、定位精度、定位方式等。如表1所示：
表1
Figure PCTCN2022114042-appb-000001
表中，网络定位可以理解为通过wifi或者数据网络来确定位置。也就是说，通过wifi或者数据网络扫描到电子设备的物理地址(mac地址)，即可与服务器上的经纬度对比，获得电子设备的地理地址。其中，网络定位包括以下有两种实现方式：第一种，WIFI小区定位，是根据WIFI路由器所在位置进行定位；第二种，基站定位，是利用基站对电子设备(如手机)的距离的测算来确定电子设备的地理位置。
表中，融合定位可以理解为融合定位技术融合了目前的所有定位方式，如GPS定位、基站定位、Wifi定位、蓝牙定位以及传感器定位等。
在一些实施例中，第二电子设备扫描到的蓝牙广播的广播时间与至少一个位置信息的获取时间的时间差大于第二阈值时，如图3所示⑩第二电子设备的查找模块调用定位模块获取位置信息，如，第二电子设备中的低功耗定位模块调用融合定位模块，通过融合定位模块获取位置信息。然后，③第二电子设备的记录模块从定位模块中获取该位置信息，记录该位置信息并将该位置信息存储在数据库中。
这里需要说明的是，第二阈值可以由系统设置，或者是查找模块周期性的将第一阈值由云端服务器下发到终端上。
第二个阶段，第二电子设备可以作为好心人设备，第二电子设备在第一个阶段获取的多个位置信息中选取第一位置信息上报至服务器，帮助第一电子设备定位所处的大概范围，以便于快速查找到第一电子设备。具体如下所述：
S400、第一电子设备开启第一电子设备的找回功能。
用户在使用第一电子设备的过程中，第一电子设备可以开启“开启离线查找”功能。具体地，如图6a-图6c所示，用户操作第一电子设备的显示界面上的设置图标，第一电子设备显示如图6a所示的界面，如设置界面。用户可以选择第一电子设备的设置界面中的“安全”功能，第一电子设备的界面由图6a所示的设置界面跳转至图6b所示的界面，如安全界面。用户选择安全界面中的“开启离线查找”功能，第一电子设备的界面由图6b所示的安全界面跳转至图6c所示的界面，如查找设备界面。当用户在查找设备界面上选择“开启离线查找”选项后，第一电子设备已开启“开启离线查找”的功能， 并能提供安全保护，如定位响铃、锁定追踪、数据保护。以第一电子设备是手机为例，若手机判断当前状态为离线状态时，则执行离线查找的功能。所述离线查找的功能包括：若手机离线时，则可以通过发送蓝牙信号，尝试向其它手机发送离线查找请求，以便其它手机将位置信息上报至服务器以供查找。
在一些实施方式中，图6c所示的查找设备界面还可以包括“查找我的手机”、“发送最后位置”、“获取位置”等功能。其中，当用户选择“找回我的手机”功能时，用户可执行手机查找的功能，具体地，可以执行以下的实施例中的丢失设备查找手机的步骤。当用户选择“发送最后位置”功能时，第一电子设备将离线前的最后位置信息发送至服务器，或者，当丢失设备的电量低于预设值时，第一电子设备向服务器发送当前的位置信息，该位置信息可以通过GPS模块获取。当用户选择“获取位置”功能时，第一电子设备在线时通过GPS获取位置信息，并发送至服务器
S401、第一电子设备确定第一电子设备处于离线状态。
具体地，所述离线状态是指第一电子设备的WIFI网络或蜂窝网络设置未开启，使第一电子设备无法登录到互联网的情况。
在一些实施例中，第一电子设备可能处于网络信号不好的环境下，这时，可能存在第一电子设备断断续续连接网络的情况。因此，在一些情况下，第一电子设备设置有预设时间。若第一电子设备离线时间超过了预设时间，则第一电子设备判断当前状态为离线状态；若第一电子设备离线时间未超过预设时间，则第一电子设备判断当前状态为非离线状态。在一些实施例中，当第一电子设备检测到用户主动关闭手机与网络的之间的连接，则第一电子设备判断当前状态为离线状态，触发以下的丢失设备找回步骤。
在一些实施例中，第一电子设备中设置有查找模块，用于判断第一电子设备的查找功能是否打开。当第一电子设备的查找功能打开时，第一电子设备实时向服务器上报电子设备的位置；同时，第一电子设备检测第一电子设备的网络状态，若第一电子设备处于离线状态时，第一电子设备执行第一电子设备离线查找的功能。
S402、第一电子设备发送蓝牙广播。相应的，第二电子设备接收到第一电子设备发送的蓝牙广播。
在一些实施例中，如图3所示，④第一电子设备的查找模块发送离线查找请求至蓝牙模块，所述离线查找请求用于调用蓝牙的接口，触发蓝牙模块发送蓝牙广播。
在一些实施例中，当第一电子设备判断当前状态为离线状态时，可直接调用蓝牙模块的接口，进而触发蓝牙模块发送蓝牙广播。在一些实施例中，当第一电子设备判断当前状态为离线状态时，即使第一电子设备并未打开蓝牙功能，或者用户在操作界面上关闭蓝牙功能，在这种场景下，并不影响第一电子设备直接调用蓝牙模块，也就是说，第一电子设备在离线状态下可以通过系统内部的指令驱动蓝牙模块发送蓝牙广播。
在一些实施例中，所述蓝牙广播携带有第一电子设备的标识，所述标识用于服务器识别第一电子设备的身份。具体地，当所述第一电子设备登录到服务器时，将第一电子设备的账号与第一电子设备的标识发送至服务器，服务器保存第一电子设备的账号和标识，当后续接收到第一电子设备的标识时，可以与对应的账号相匹配。
在一些实施例中，所述蓝牙广播携带有第一电子设备的公钥P。在一些实施方式中，所述第一电子设备每隔一段时间(例如一天)更新公钥信息，在这种情况下，第一电子设备可以预先将后续即将更新(例如后续14天)的公钥信息发送至服务端。具体地，电子设备在丢失后的第二天才通过其它设备将公钥上传至服务器，这时，由于服务器预先存储了丢失后14天内的公钥信息，因此，可以根据预先存储的公钥信息匹配出对应的设备信息。
在这种实现方式中，蓝牙广播并不直接传输第一电子设备的公钥信息，这样，使得接收到蓝牙广播的其它设备并无法得知第一电子设备的具体信息，可以提高了第一电子设备的安全性，此外，周期性的更新公钥，可以避免公钥信息被跟踪破解的问题，提高了信息传输的安全性，保护了丢失设备的用户隐私。
在一些实施例中，所述蓝牙广播的报文中携带有丢失标识，例如是在蓝牙报文中某一标识位标识为“丢失设备”，这样，当接收的电子设备接收到所述蓝牙广播时，可以触发后续向服务器进一步确认的步骤。
在一些实施例中，所述蓝牙广播的报文中携带有事件码，例如事件码为01代表是指示电子设备接收到所述蓝牙广播时，可以触发后续向服务器进一步确认的步骤；事件码为02代表是指示电子设备接收到所述蓝牙广播时，可以触发后续向服务器上报位置的步骤；所述第二电子设备在接收到所述报文后，可以识别出所述事件码对应的事件，并根据事件码执行对应的事件。
在一些实施例中，如图3所示，⑤第一电子设备100的蓝牙模块向第二电子设备200的蓝牙模块发送蓝牙广播。相应的，第二电子设备200通过蓝牙模块接收第一电子设备发送的蓝牙广播。
在一些实施例中，所述第二电子设备可以是丢失设备周边的任一设备，所述第二电子设备与所述第一电子设备可以进行蓝牙通信。用户可以在第二电子设备的设置中打开蓝牙功能，在第二电子设备在蓝牙功能开启后，第二电子设备可监听第一电子设备的发送的广播，并协助第一电子设备进行定位。
在一些实施方式中，第一电子设备100的蓝牙模块在发送蓝牙广播时以预设的发射频率进行蓝牙广播，例如，每隔预设T时间发送一次，并且发送蓝牙广播的时长为X秒，在这X秒中，蓝牙广播信息持续不间断的进行发送。对应地，第二电子设备200的蓝牙模块在进行信号扫描时，以预设的扫描频率进行扫描，所述预设第二电子设备每隔y秒扫描一次，并且每次扫描时长z秒。
其中，只要第一电子设备发起了广播，第二电子设备就可以接收到广播。示例性的，第二电子设备可以每隔600ms扫描一次，每次扫描时长为100ms。
S403、当第二电子设备扫描到蓝牙广播时，第二电子设备记录蓝牙广播对应的广播信息。
如图3所示的，⑥当第二电子设备扫描到第一电子设备发的蓝牙广播(如BLE广播)后，第二电子设备记录蓝牙广播并以广播信息的形式存储在数据库中。
该广播信息可以包括如表2所示的广播时间(或称扫描时间)、BLE广播报文、MAC地址、信号强度RSSI等。
如表2所示：
表2
Figure PCTCN2022114042-appb-000002
S404、第二电子设备根据蓝牙广播获取第一位置信息。
如图3所示，在第二电子设备200扫描到蓝牙广播后，⑦第二电子设备200中的查找模块根据蓝牙广播的广播时间，从记录模块中查找第二电子设备200获取的至少一个位置信息并获取至少一个位置信息的获取时间。查找模块根据广播时间获取到第一位置信息，该第一位置信息为至少一个位置信息中的至少一个。
在一些示例中，S404具体可实现为：
S4041、第二电子设备根据蓝牙广播获取广播时间及至少一个位置信息的获取时间。
当第二电子设备扫描到蓝牙广播时，第二电子设备获取蓝牙广播的广播时间，并获取数据库中存储的至少一个位置信息的获取时间。
S4042、第二电子设备根据广播时间及与至少一个位置信息的获取时间，获取第一位置信息。
应理解为，第二电子设备将广播时间与至少一个位置信息的获取时间进行比对。第二电子设备将满足条件的至少一个位置信息作为第一位置信息。
其中，条件可以包括以下几项中的一项：广播时间与位置信息的获取时间的时间差最小；广播时间与位置信息的获取时间的时间差小于第一阈值；广播时间与位置信息的获取时间的时间差最小，且最小时间差小于第一阈值。
在一种具体可实现方式中，第二电子设备确定至少一个位置信息的获取时间和广播时间的时间差最小。第二电子设备将最小时间差对应的至少一个位置信息作为第一位置信息。
示例性的，如上表1和表2的示例中，第二电子设备存储有一个位置信息，该位置信息L1的定位时间为：2021.7.1 16:30:00:020。当第二电子设备扫描到第一蓝牙广播B1时，第一蓝牙广播的广播时间为：2021.7.1 16:31:10:121，第二电子设备计算L1与B1的时间差值为1分10秒101毫秒。当第二电子设备扫描到第二蓝牙广播B2时，第二蓝牙广播的广播时间为：2021.7.1 16:34:22:560，第二电子设备计算L1与B2的时间差值为4分钟22秒540毫秒。可见，将L1用于B1的定位可信度高，L1用于B2的定位可信度低。
如上表1和表2的示例中，第二电子设备存储有多个位置信息，第二电子设备还存储位置信息L2。该位置信息L2的定位时间为：2021.7.1 16:35:22:560。当第二电子设备扫描到第一蓝牙广播B1时，第一蓝牙广播的广播时间为：2021.7.1 16:31:10:121，第二电子设备计算L2与B1的时间差值为4分12秒330毫秒。当第二电子设备扫描 到第二蓝牙广播B2时，第二蓝牙广播的广播时间为：2021.7.1 16:34:22:560，第二电子设备计算L2与B2的时间差值为1分钟。当第二电子设备扫描到第三蓝牙广播B3时，第三蓝牙广播的广播时间为：2021.7.1 16:40:00:230，第二电子设备计算L2与B3的时间差值为4分37秒670毫秒。故将L2用于B2的定位可信度高，将L2用于B1的定位可信度中，将L2用于B3的定位可信度低。
可见，L1用于B1的定位，L2用于B2的定位。当第二电子设备接收到第一电子设备发送的广播B1时，第二电子设备确定L1作为第二电子设备的位置信息；当第二电子设备接收到第一电子设备发送的广播B2时，第二电子设备确定L2作为第二电子设备的位置信息。
在另一种具体可实现方式中，为了更精确选取第一位置信息，上述最小的时间差小于第一阈值。也就是说，第二电子设备确定广播时间与至少一个位置信息的获取时间的时间差最小，且小于第一阈值，第二电子设备将最小时间差对应的至少一个位置信息作为第一位置信息。其中，第一阈值可以由系统设置，或者是查找模块周期性的将第一阈值由云端服务器下发到终端上。示例性的，第一阈值可以为5分钟或4分钟，本申请实施例不做具体限定，具体实施时需要根据实际情况确定。
在又一种具体可实现方式中，第二电子设备确定至少一个位置信息的获取时间和广播时间的时间差小于第一阈值。第二电子设备将小于第一阈值对应的至少一个位置信息作为第一位置信息。
示例性的，假设第一阈值为5分钟，如上表1和表2的示例中，第二电子设备存储有多个位置信息，如第二电子设备存储了位置信息L1和位置信息L2。第二电子设备计算L1与B1的时间差值为1分10秒101毫秒，L1与B2的时间差值为4分钟22秒540毫秒，L2与B1的时间差值为4分12秒330毫秒，L2与B2的时间差值为1分钟，L2与B3的时间差值为4分37秒670毫秒。这些时间差值均小于5分钟。所以，当第二电子设备接收到第一电子设备发送的广播B1时，第二电子设备确定L1和L2作为第二电子设备的位置信息；当第二电子设备接收到第一电子设备发送的广播B2时，第二电子设备确定L1、L2作为第二电子设备的位置信息。当第二电子设备接收到第一电子设备发送的广播B3时，第二电子设备确定L2作为第二电子设备的位置信息。
因此，在本申请实施例中，第二电子设备可以利用第二电子设备上的其他应用程序获取的位置信息，而非，第二电子设备扫描到蓝牙广播时，无需频繁通过调用第二应用程序获取的位置信息，这样，可以有效减少功耗，同时可以实现多次上报位置信息的效果，使得查找丢失设备的效率较高。
当然，若第二电子设备将广播时间与至少一个位置信息的获取时间的时间差不满足上述条件，则第二电子设备实时获取位置信息，并将实时获取的位置信息作为第一位置信息。示例性的，如图3所示⑩第二电子设备的查找模块调用定位模块实时获取位置信息，如，第二电子设备中的低功耗定位模块调用融合定位模块，通过融合定位模块获取位置信息。然后，③第二电子设备200的记录模块从定位模块中获取该位置信息，记录该位置信息并将该位置信息存储在数据库中。⑦第二电子设备200中的查找模块根据蓝牙广播的广播时间，从记录模块中查找第二电子设备200获取的位置信 息，并将该位置信息作为第一位置信息。
在一些实施例中，如图4b所示，在执行S404之后，本申请实施例提供的设备查找方法还可以包括：
S410、第二电子设备检测第二电子设备是否连网。若第二电子设备检测到第二电子设备连网，则执行S405；若第二电子设备未检测到第二电子设备连网，则执行S411。
在一种实施例中，第二电子设备连网可以理解为第二电子设备由第四应用程序开启连网。也就是说，用户为了使用第二电子设备上的第四应用程序，用户触发第二电子设备开启连网操作，使得第二电子设备连网。
其中，第四应用程序可以理解为第二电子设备上任一应用程序，例如，外卖类应用程序、打车类应用程序、旅游类应用程序、新闻类应用程序、娱乐类应用程序等。本申请实施例中不对第四应用程序做具体限定。
在一些实施例中，当第二电子设备检测到有第三应用程序向所述服务器上报数据时，第二电子设备将第一位置信息上报给服务器。也就是说，第二电子设备检测到第二电子设备上的多个应用程序中存在一个应用程序与服务器交互时，第二电子设备就将第一位置信息上报给服务器。在一种具体可实现方式中，本申请实施例中所述的服务器与第三应用程序的服务器为同一服务器。这样，无需第二电子设备刻意启动网络来上报位置信息，可以减少单独开启网络的功耗，及减少AP唤醒的功耗。
S411、第二电子设备不上报第二位置信息给服务器。
本申请实施例中，第二电子设备检测第二电子设备是否由第四应用程序开启连网。若第二电子设备检测到第二电子设备由第四应用程序开启连网，则第二电子设备就将第一位置信息上报给服务器。这样，无需第二电子设备刻意启动网络来上报位置信息，从而降低AP唤醒和开启网络的功耗。
S405、第二电子设备将第一位置信息以及第一电子设备的设备信息上报给服务器。
如图3所示，⑧第二电子设备200中的查找模块将查找到的第一位置信息及第一电子设备的设备信息，发送给低功耗上报模块。⑨低功耗上报模块将第一位置信息及第一电子设备的设备信息上报给服务器。
其中，第一位置信息的数量可以是一个，也可以是多个，本申请实施例不做具体限定。
具体地，第一电子设备的设备信息可以包括第一电子设备的标识或第一电子设备的公钥信息，第一电子设备的标识或第一电子设备的公钥信息可以从第一电子设备发送的蓝牙广播中获得，第一电子设备的设备信息用于指示服务器根据第一电子设备的设备信息将第二电子设备位置信息与第一电子设备账号相匹配。
在一些实施例中，第一电子设备可以与第二电子设备进行蓝牙短距通信时，两个设备之间的物理距离会在一定范围之内，例如大概10米的范围，将第二电子设备的位置作为第一电子设备的附近位置上报给服务器，供用户查阅。具体地，第二电子设备将第一位置信息加密后上报给服务器。如上示例，第二电子设备将L1的定位经纬度和定位精度进行加密之后，上报给服务器。例如，第一电子设备发送的蓝牙广播中携带公钥P的派生公钥Pi。第二电子设备将第一位置信息采用椭圆曲线集成加密方案(elliptic Curve integrated encryption scheme，ECIES)算法加密，得到第一位置信息的 密文，该第一位置信息的密文中携带公钥Pi的Hash密文。
在一些实施例中，第二电子设备根据S405中第一电子设备发送的离线定位请求上报位置信息给服务器。当然，第二电子设备也可以根据自身情况(如下文所述第二电子设备检测到有其他应用程序向服务器上报数据等)决定是否向服务器上报位置信息。或者，第二电子设备也可以在接收服务器发送的上报指令上报位置信息，如，下文第三电子设备请求服务器查询第一电子设备的位置信息时，服务器向第二电子设备发送上报位置信息的指令，此时，第二电子设备可以上报位置信息给服务器。
在一些实施例中，当第二电子设备接收到第一电子设备发送的广播时，第二电子设备确定的位置信息的数量为多个，第二电子设备将这些位置信息批量上报服务器。示例性的，如上示例，当第二电子设备接收到第一电子设备发送的广播B1时，第二电子设备确定L1和L2作为第二电子设备的位置信息。第二电子设备可以将位置信息L1和位置信息L2一同上报给服务器。
在一些实施例中，当第二电子设备接收到第一电子设备发送的广播时，无论第二电子设备确定的位置信息的数量是一个还是多个。第二电子设备可以将一段时间的位置信息批量上报服务器。示例性的，如上示例，第二电子设备确定2021.7.1 16:31:10:121的位置信息L1，及2021.7.1 16:34:22:560位置信息L2。第二电子设备可以将位置信息L1和位置信息L2一同上报给服务器。
在本申请实施例中，相较于第二电子设备确定一个位置信息就上报一次服务器来说，第二电子设备批量上报位置信息给服务器更能有效的节省功耗。
S406、服务器根据更新信息，更新第一电子设备的位置信息。
服务器根据第一电子设备的设备信息将所述第二电子设备位置信息与第一电子设备的账号相匹配，具体地，服务器可以根据第一电子设备的设备信息包括第一电子设备的标识或第一电子设备的公钥信息确定第一电子设备的账号。所述更新第一电子设备的位置信息包括：将第二电子设备的位置信息记录为第一电子设备周围的位置信息，这样，第二电子设备的位置与第一电子设备，第一电子设备的账号建立了关联关系。
在一些实施例中，第一电子设备周围可能存在多个第二电子设备，此时，更新第一电子设备的位置信息具体包括：服务器可以将多个第二电子设备的位置信息与第一电子设备的账号相匹配，将多个第二电子设备的位置信息记录为第一电子设备周围的位置信息。
S407、第三电子设备向服务器发送查询请求，查询请求用于请求查询第一电子设备的位置信息。
如图3所示，
