目前，绝大多数的追踪类可穿戴电子设备(Tracker类产品)的定位功能都是由定位模块(一般通过融合定位获取Tracker地理位置坐标)和数据通信模块(通过无线网络将位置信息上传到云端服务器)实现。一旦定位功能相关模块出现异常，则该产品完全无法正常工作。并且，Tracker类产品对功耗有较高的要求，在实时定位时，定位功能必须保持工作状态，对产品的功耗和续航能力是极大的考验。
针对于上述问题，本公开实施例提供了一种定位***，如图1所示，包括：云端服务器2、与云端服务器2通信连接的可穿戴电子设备1以及辅助定位设备3。其中，可穿戴电子设备1和辅助定位设备3中均内置有短距离无线通信模块，短距离无线通信模块例如：蓝牙模块、无线WIFI模块、ZigBee模块等。
可穿戴电子设备1和辅助定位设备3均通过无线通信模块与云端服务器2进行通信，这样可穿戴电子设备1和辅助定位设备3可以接收云端服务器2的指令并将自身的相关信息发送到云端服务器2，可穿戴电子设备1与辅助定位设备3之间可通过短距离无线通信模块相互通信。
辅助定位设备3可以是追踪类可穿戴设备即Tracker设备或其它具有短距离通信模块的可访问互联网的设备，在一实施方式中，可分为三类：固定位置辅助设备(以下称为FLT，放置在固定位置，如：建筑物、电线杆等)，若该设备为Tracker，则无需定位模块，该设备也可以是其它通信设备(如：无线路由器)；固定路线辅助设备(以下称为RRT，放置在固定路线交通工具上，如：公交车、地铁、高铁等)，若该设备为Tracker，则无需定位模块，该设备也可以是其它通信设备(如：车联网设备)；自由路线辅助设备(以下称为FRT，放置 其它交通工具上)，该设备可以是Tracker或其它通信设备(如：车联网设备)。所有辅助定位设备都采用外接电源供电。
本实施例定位***中各设备的作用如下。
可穿戴电子设备1发送辅助定位请求至云端服务器2，辅助定位请求包括可穿戴电子设备1的位置信息。可有多种发送请求的条件，例如，用户手动发送请求，根据可穿戴电子设备1的电量值自动发送请求等。例如：当可穿戴电子设备1的定位模块损坏或者可穿戴电子设备1的电量不足时，可自动触发可穿戴电子设备1发送辅助定位请求。
云端服务器2响应于辅助定位请求，根据可穿戴电子设备1的位置信息查找预设范围内的辅助定位设备3，若查找到，则向可穿戴电子设备1发送进入辅助定位模式指令，并向预设范围内的辅助定位设备3发送可穿戴电子设备1进入指令。
可穿戴电子设备1响应于进入辅助定位模式指令，关闭定位模块并开启短距离无线通信模块。可穿戴电子设备1预先设有辅助定位模式，辅助定位模式时可穿戴电子设备1的定位模块关闭、短距离无线通信模块开启。
可穿戴电子设备1进入指令包括该可穿戴电子设备1的设备信息，例如设备ID。辅助定位设备3响应于进入指令，将可穿戴电子设备1的设备信息存储于支持设备列表中并开启短距离无线通信模块，搜索附近可穿戴电子设备1的设备信息，并与支持设备列表中的设备信息进行匹配，若存在匹配的可穿戴电子设备1，根据自身位置信息以及可穿戴电子设备1的设备信息生成辅助定位信息，并将辅助定位信息发送至云端服务器2。
在一实施方式中，辅助定位设备3在接收到可穿戴电子设备1进入指令时，解析该进入指令获取可穿戴电子设备1的设备信息，并响应于进入指令将可穿戴电子设备1的设备信息存储于辅助定位设备3的支持设备列表中，由于1个辅助定位设备3的附近可能会有1个或多个需要辅助定位的可穿戴电子设备1，1个辅助定位设备3可支持1个或多个需要辅助定位的可穿戴电子设备1，因此，支持设备列表中可包括1个或多个可穿戴电子设备1的设备信息。
辅助定位设备3响应于进入指令还开启辅助定位设备3的短距离无线通信模块，利用短距离无线通信模块来搜索附近可穿戴电子设备1的设备信息，并将搜索到的可穿戴电子设备1的设备信息与支持设备列表中的可穿戴电子设备1的设备信息进行匹配，若匹配成功，则表明支持设备列表中的可穿戴电子设备1在该辅助定位设备3的附近，此时，可根据该辅助定位设备3的位置信息来确定在该辅助定位设备3附近的可穿戴电子设备1的位置信息。假设匹配成功的可穿戴电子设备1的设备信息包括多个，此时，辅助定位设备3根据自身的位 置信息以及附近的可穿戴电子设备1的设备信息生成辅助定位信息，每个可穿戴电子设备1的设备信息对应一组辅助定位信息，该辅助定位信息用于确定该辅助定位设备3附近的可穿戴电子设备1的位置信息。辅助定位设备3将生成的1组或多组辅助定位信息发送至云端服务器2。
其中，对于不同类型的辅助定位设备3，其自身的位置信息获取方式不同。若辅助定位设备3为固定位置辅助设备FLT，由于放置在固定位置，位置信息是一个固定值，所以无需定位模块，当需要进行辅助定位时，辅助定位设备3每次向云端服务器2发送自身固定位置即可。若辅助定位设备3为固定路线辅助设备RRT，由于移动路线固定，每次进行固定路线移动的里程数和里程数对应的位置信息也是固定的，所以只需根据里程数即可对应位置信息。RRT获取位置的详细方法如下：由于RRT为固定线路，所以固定路线上每个里程数可对应一个确定位置坐标，将里程数与位置的对应表存储在RRT中，每次在进行固定线路移动之前将位置计算里程数清零，即可根据里程数找到对应位置。若辅助定位设备3为自由路线辅助设备FRT与可穿戴电子设备1的功能基本相同。本实施例中设置不同类型的辅助定位设备3，根据不同类型辅助定位设备3的特点，利用辅助定位设备3为正常使用的Tracker定位并进行位置信息上报，可有效降低正常使用的Tracker的功耗，增加Tracker产品的续航能力，并且能够在定位模块和网络模块无法工作时保证Tracker设备的正常定位；且辅助定位设备3外接电源无需考虑功耗问题。
云端服务器2根据辅助定位信息确定与辅助定位设备3匹配成功的可穿戴电子设备1的位置信息。云端服务器2接收到辅助定位信息后解析该信息，得到辅助定位设备3的位置信息以及可穿戴电子设备1的设备信息，并根据辅助定位设备3的位置信息来确定可穿戴电子设备1的设备信息。
在一实施方式中，辅助定位信息还包括辅助定位设备3的短距离信号强度，云端服务器2若接收到与同一可穿戴电子设备1相关的多个辅助定位信息。由于辅助定位设备3与可穿戴电子设备1的位置越近，辅助定位设备3的短距离信号强度越强，因此，可选取这多个辅助定位信息中短距离信号强度最强的辅助定位设备3的位置信息，用短距离信号强度最强的辅助定位设备3的位置信息来确定可穿戴电子设备1的位置信息，进一步保证可穿戴电子设备1的位置信息的准确性。
本实施例中可穿戴电子设备1在接收到云端服务器2发送的进入辅助定位模式指令时，响应于进入辅助定位模式指令关闭定位模块并开启短距离无线通信模块，由云端服务器2根据辅助定位设备3发送的辅助定位信息确定可穿戴电子设备1的位置信息。如此，即使可穿 戴电子设备1即Tracker类设备的定位模块出现异常，也能够借助辅助定位设备3实现定位功能；且由于借助辅助定位设备3实现定位功能时无需开启定位模块，功耗较低。
在一些例子中，云端服务器2还用于若未查找到预设范围内的辅助定位设备3，则向可穿戴电子设备1发送退出辅助定位模式的指令，可穿戴电子设备1响应于退出指令开启定位模块。也就是说，若云端服务器2未查找到在可穿戴电子设备1所在位置预设范围内的辅助定位设备3，则说明在该可穿戴电子设备1的附近没有辅助定位设备3，无法借助辅助定位设备3来确定可穿戴电子设备1的位置信息，此时，云端服务器2向可穿戴电子设备1发送退出辅助定位模式的指令，可穿戴电子设备1响应于退出指令开启定位模块并关闭短距离无线通信模块。
在一些例子中，辅助定位设备3还用于若在预设时长内或预设次数内未搜索到支持设备列表内的可穿戴电子设备1的设备信息，则将未搜索到的可穿戴电子设备1的设备信息从支持设备列表中删除；若支持设备列表被清空，则关闭短距离无线通信模块。
本实施例中将支持设备列表中预设时长内或预设次数内未搜索到的可穿戴电子设备1的设备信息删除，避免支持设备列表中不可用的可穿戴电子设备1的设备信息过多，而导致辅助定位设备3在匹配可穿戴电子设备1的设备信息时耗时较长。若支持设备列表被清空，则关闭蓝牙模块，降低辅助定位设备3的功耗。
下面结合附图2以短距离无线通信模块为蓝牙BLE模块进行说明，其中，NT指代可穿戴电子设备1，CS指代云端服务器2，AT指代辅助定位设备3。
NT向CS发送进入辅助定位模式请求(可有多种发送请求条件，如：用户手动发送请求、根据电量值自动发送请求等)；CS根据NT上报的地理位置查找其有效半径内的AT，若查找到，则CS向NT发送可以进入辅助定位模式指令，同时向查找到的所有AT发送包含NT设备信息的NT进入指令；NT收到指令后关闭定位和数据通信模块并进入BLE Slave模式开启BLE长广播，AT收到指令后将NT的设备信息加入自身的NT设备列表并开启BLE Master模式搜索辅助设备列表中设备的长广播。
若ATi(第i个AT)搜索到的BLE设备在自身NT设备列表中，则ATi将该NT设备信息、自身位置信息以及BLE信号强度拼装成消息发送给CS；CS收到ATi发送的位置信息消息后将ATi的位置信息作为NT的位置信息，若同一时间CS收到了同一NT的多个位置上报，则选择BLE信号强度最高的位置信息作为NT的位置，同时CS再查找ATi有效半径内的AT，若查找到，则向查找到的所有AT发送包含NT设备信息的NT进入指令。
若CS未查询到可用AT，则发消息给NT退出辅助定位模式；若AT在预设的搜索时间 或次数内未搜索到NT设备列表中的某个NT，则将该NT从NT设备列表中删除；若AT的NT设备列表中被清空，则AT关闭蓝牙。
本实施例中的定位***可应用于目前追踪类设备常用的应用场景，主要应用环境是城市交通环境，对追踪类设备城市交通环境内的实时定位功能能起到较好的改进效果。Tracker类产品扩展了定位方式，提高了相关产品的健壮性和可用性。
本公开实施例提供了一种辅助定位方法，应用于包括短距离无线通信模块的可穿戴电子设备。本公开中辅助定位方法的流程图如图3所示，包括步骤S11至S14。
步骤S11：发送辅助定位请求至云端服务器，由云端服务器查找可穿戴电子设备的有效范围内是否存在辅助定位设备。
在一实施方式中，本实施例可有多种发送请求条件，用户手动发送请求、根据可穿戴电子设备的电量值自动发送请求等。例如：当可穿戴电子设备的定位模块损坏或者可穿戴电子设备的电量不足时，可自动触发可穿戴电子设备发送辅助定位请求。
辅助定位请求包括可穿戴电子设备的位置信息，云端服务器响应于辅助定位请求，根据可穿戴电子设备的位置信息查找预设范围内的辅助定位设备。
步骤S12：判断是否接收到云端服务器发送的进入辅助定位模式指令。
步骤S13：响应于进入辅助定位模式指令关闭定位模块并开启短距离无线通信模块，由云端服务器根据辅助定位设备确定可穿戴电子设备的位置信息。
在一实施方式中，可穿戴电子设备预先设有辅助定位模式，辅助定位模式时可穿戴电子设备的定位模块关闭、短距离无线通信模块开启。若云端服务器查找到在可穿戴电子设备所在位置预设范围内的辅助定位设备，则云端服务器向可穿戴电子设备发送进入辅助定位模式指令。可穿戴电子设备响应于进入辅助定位模式指令进入辅助定位模式时，由云端服务器根据其预设范围内的辅助定位设备确定可穿戴电子设备的位置信息，如此，即使可穿戴电子设备即Tracker类设备的定位模块出现异常，也能够借助辅助定位设备实现定位功能；且由于借助辅助定位设备实现定位功能时无需开启定位模块，功耗较低。
步骤S14：接收来自云端服务器发送的退出辅助定位模式的指令，可穿戴电子设备响应于退出指令开启定位模块。
在一实施方式中，若云端服务器未查找到在可穿戴电子设备所在位置预设范围内的辅助定位设备，则说明在该可穿戴电子设备的附近没有辅助定位设备，无法借助辅助定位设备来确定可穿戴电子设备的位置信息，此时，云端服务器向可穿戴电子设备发送退出辅助定位模 式的指令，可穿戴电子设备响应于退出指令开启定位模块并关闭短距离无线通信模块。
下面结合附图2以短距离无线通信模块为蓝牙BLE模块进行说明，NT指代可穿戴电子设备，CS指代云端服务器，AT指代辅助定位设备。
NT向CS发送进入辅助定位模式请求，CS根据NT上报的位置信息查找其有效半径内的AT，若查找到，则CS向NT发送可以进入辅助定位模式指令，同时向查找到的所有AT发送包含NT设备信息的NT进入指令。若NT没有收到CS下发的进入辅助定位模式指令或收到CS下发的无法进入辅助定位模式指令，则保持正常状态；若NT收到了CS下发的进入辅助定位模式指令，则关闭定位模块，NT开启BLE Slave模式并触发BLE长广播，NT进入辅助定位模式。此时，由云端服务器根据辅助定位设备来确定可穿戴电子设备的位置信息。
本公开实施例提供了一种辅助定位方法，应用于云端服务器。本公开中辅助定位方法的流程图如图4所示，包括步骤S21至S26。
步骤S21：接收来自可穿戴电子设备的辅助定位请求，辅助定位请求包括可穿戴电子设备的位置信息。
在一实施方式中，当可穿戴电子设备的定位模块损坏或者可穿戴电子设备的电量不足时，可自动触发可穿戴电子设备发送辅助定位请求。云端服务器接收来自可穿戴电子设备的辅助定位请求，辅助定位请求包括可穿戴电子设备的位置信息。
步骤S22：根据可穿戴电子设备的位置信息判断是否查找到预设范围内的辅助定位设备。若查找到，则执行步骤S23；若未查找到，则执行步骤S26。
步骤S23：向可穿戴电子设备发送进入辅助定位模式指令，并向预设范围内的辅助定位设备发送可穿戴电子设备进入指令，其中，可穿戴电子设备响应于进入辅助定位模式指令关闭定位模块并开启短距离无线通信模块，可穿戴电子设备进入指令包括可穿戴电子设备的设备信息。
针对上述步骤S22和S23，在一实施方式中，云端服务器响应于辅助定位请求，根据可穿戴电子设备的位置信息查找预设范围内的辅助定位设备，若查找到，则向可穿戴电子设备发送进入辅助定位模式指令，并向预设范围内的辅助定位设备发送可穿戴电子设备进入指令。
可穿戴电子设备响应于进入辅助定位模式指令，关闭定位模块并开启短距离无线通信模块。
辅助定位设备响应于进入指令还开启辅助定位设备的短距离无线通信模块，利用短距离无线通信模块来搜索附近可穿戴电子设备的设备信息，并将搜索到的可穿戴电子设备的设备 信息与支持设备列表中的可穿戴电子设备的设备信息进行匹配，若匹配成功，则表明支持设备列表中的可穿戴电子设备在该辅助定位设备的附近，此时，可根据该辅助定位设备的位置信息来确定在该辅助定位设备附近的可穿戴电子设备的位置信息。假设匹配成功的可穿戴电子设备的设备信息包括多个，此时，辅助定位设备根据自身的位置信息以及附近的可穿戴电子设备的设备信息生成辅助定位信息，每个可穿戴电子设备的设备信息对应一组辅助定位信息，该辅助定位信息用于确定该辅助定位设备附近的可穿戴电子设备的位置信息。辅助定位设备将生成的1组或多组辅助定位信息发送至云端服务器。
步骤S24：接收来自辅助定位设备的辅助定位信息，辅助定位信息包括辅助定位设备的位置信息、与辅助定位设备匹配成功的可穿戴电子设备的设备信息。
步骤S25：根据辅助定位信息确定与辅助定位设备匹配成功的可穿戴电子设备的位置信息。
针对上述步骤S24和S25，在一实施方式中，云端服务器接收到辅助定位信息后解析该信息，得到辅助定位设备的位置信息以及可穿戴电子设备的设备信息，并根据辅助定位设备的位置信息来确定可穿戴电子设备的位置信息。本实施例中由云端服务器根据辅助定位设备发送的辅助定位信息确定可穿戴电子设备的位置信息。如此，即使可穿戴电子设备即Tracker类设备的定位模块出现异常，也能够借助辅助定位设备实现定位功能；且由于借助辅助定位设备实现定位功能时无需开启定位模块，功耗较低。
在一些例子中，根据辅助定位信息确定与辅助定位设备匹配成功的可穿戴电子设备的位置信息，包括：将辅助定位设备的位置信息确定为可穿戴电子设备的位置信息。本实施例中可直接将可穿戴电子设备附近的辅助定位设备的位置信息确定为可穿戴电子设备的位置信息。
在一些例子中，辅助定位信息还包括辅助定位设备的短距离信号强度；接收来自辅助定位设备的辅助定位信息包括：接收来自多个辅助定位设备的多个辅助定位信息；根据辅助定位信息确定与辅助定位设备匹配成功的可穿戴电子设备的位置信息，包括：确定短距离信号强度最强的辅助定位设备；将短距离信号强度最强的辅助定位设备的位置信息确定为可穿戴电子设备的位置信息。
辅助定位信息不仅包括可穿戴电子设备的设备信息、辅助定位设备的位置信息，还包括辅助定位设备的短信号强度信息，如此，云端服务器若接收到与同一可穿戴电子设备相关的多个辅助定位信息。由于辅助定位设备与可穿戴电子设备的位置越近，辅助定位设备的短距离信号强度越强，因此，可选取这多个辅助定位信息中短距离信号强度最强的辅助定位设备 的位置信息，用短距离信号强度最强的辅助定位设备的位置信息来确定可穿戴电子设备的位置信息，进一步保证可穿戴电子设备的位置信息的准确性。
步骤S26：向可穿戴电子设备发送退出辅助定位模式的指令，可穿戴电子设备响应于退出指令开启定位模块。
在一实施方式中，云端服务器未查找到在可穿戴电子设备所在位置预设范围内的辅助定位设备，则说明在该可穿戴电子设备的附近没有辅助定位设备，无法借助辅助定位设备来确定可穿戴电子设备的位置信息，此时，云端服务器向可穿戴电子设备发送退出辅助定位模式的指令，可穿戴电子设备响应于退出指令开启定位模块并关闭短距离无线通信模块。
下面结合附图2以短距离无线通信模块为蓝牙BLE模块对在云端服务器执行的辅助定位方法进行说明，NT指代可穿戴电子设备，CS指代云端服务器，AT指代辅助定位设备。CS收到NT发送的进入辅助模式请求，CS响应于进入辅助模式请求根据NT的位置信息查找NT有效半径范围内是否存在AT，若NT有效半径范围内不存在AT，则CS向NT下发无法进入辅助定位模式指令；若NT有效半径范围内存在AT，则CS向所有目标AT发送NT进入辅助定位模式指令。
CS收到某个AT(ATi)发送的辅助定位信息(包括NT设备信息、以及该AT的位置消息)，CS解析辅助定位信息中的NT设备信息以及AT的位置消息，从而根据AT的位置消息确定NT设备信息。
本公开实施例提供了一种辅助定位方法，应用于包括短距离无线通信模块的辅助定位设备。本公开中辅助定位方法的流程图如图5所示，包括步骤S31至S38。
步骤S31：接收来自云端服务器的可穿戴电子设备进入指令，可穿戴电子设备进入指令包括可穿戴电子设备的设备信息。
在一实施方式中，当可穿戴电子设备的定位模块损坏或者可穿戴电子设备的电量不足时，可自动触发可穿戴电子设备发送辅助定位请求。云端服务器接收来自可穿戴电子设备的辅助定位请求，辅助定位请求包括可穿戴电子设备的位置信息。云端服务器响应于辅助定位请求，根据可穿戴电子设备的位置信息查找预设范围内的辅助定位设备，若查找到，则向可穿戴电子设备发送进入辅助定位模式指令，并向预设范围内的辅助定位设备发送可穿戴电子设备进入指令。
辅助定位设备则接收来自云端服务器的可穿戴电子设备进入指令，该可穿戴电子设备进入指令包括可穿戴电子设备的设备信息，例如设备ID。
步骤S32：响应于进入指令，将可穿戴电子设备的设备信息存储于支持设备列表中并开启短距离无线通信模块。
步骤S33：搜索附近可穿戴电子设备的设备信息，并与支持设备列表中的设备信息进行匹配。
步骤S34：判断搜索到的附近可穿戴电子设备的设备信息与支持设备列表中的设备信息是否匹配。若匹配，则执行步骤S35；若不匹配，则执行步骤S37。
步骤S35：根据自身位置信息以及可穿戴电子设备的设备信息生成辅助定位信息。
步骤S36：将辅助定位信息发送至云端服务器，由云端服务器根据辅助定位信息确定可穿戴电子设备的位置信息。
步骤S37：确定在预设时长内或预设次数内未搜索到支持设备列表内的可穿戴电子设备的设备信息。
步骤S38：将未搜索到的可穿戴电子设备的设备信息从支持设备列表中删除。
在一实施方式中，辅助定位设备响应于进入指令将可穿戴电子设备的设备信息存储于支持设备列表中，还开启辅助定位设备的短距离无线通信模块，利用短距离无线通信模块来搜索附近可穿戴电子设备的设备信息，并将搜索到的可穿戴电子设备的设备信息与支持设备列表中的可穿戴电子设备的设备信息进行匹配。
若匹配成功，则表明支持设备列表中的可穿戴电子设备在该辅助定位设备的附近，此时，根据自身位置信息以及可穿戴电子设备的设备信息生成辅助定位信息，并将辅助定位信息发送至云端服务器，由云端服务器根据该辅助定位设备的位置信息来确定在该辅助定位设备附近的可穿戴电子设备的位置信息。
假设匹配成功的可穿戴电子设备的设备信息包括多个，此时，辅助定位设备根据自身的位置信息以及附近的可穿戴电子设备的设备信息生成辅助定位信息，每个可穿戴电子设备的设备信息对应一组辅助定位信息，该辅助定位信息用于确定该辅助定位设备附近的可穿戴电子设备的位置信息。辅助定位设备将生成的1组或多组辅助定位信息发送至云端服务器。
若未匹配成功，则确定在预设时长内或预设次数内未搜索到支持设备列表内的可穿戴电子设备的设备信息，并将支持设备列表中预设时长内或预设次数内未搜索到的可穿戴电子设备的设备信息删除，避免支持设备列表中不可用的可穿戴电子设备的设备信息过多，而导致辅助定位设备在匹配可穿戴电子设备的设备信息时耗时较长。若支持设备列表被清空，则关闭蓝牙模块，降低辅助定位设备的功耗。
在一些例子中，根据自身位置信息以及可穿戴电子设备的设备信息生成辅助定位信息包 括：根据自身位置信息、短距离无线通信模块的短距离信号强度信息以及可穿戴电子设备的设备信息共同生成辅助定位信息。
在一实施方式中，由于辅助定位设备与可穿戴电子设备的位置越近，辅助定位设备的短距离信号强度越强，因此，对于多辅助定位设备的场景下，辅助定位信息还包括辅助定位设备的短距离信号强度。云端服务器可接收来自多个辅助定位设备的辅助定位信息，并选取这多个辅助定位信息中短距离信号强度最强的辅助定位设备的位置信息，用短距离信号强度最强的辅助定位设备的位置信息来确定可穿戴电子设备的位置信息，进一步保证可穿戴电子设备的位置信息的准确性。
在一些例子中，若支持设备列表被清空，则关闭短距离无线通信模块，降低辅助定位设备的功耗。
下面结合附图2以短距离无线通信模块为蓝牙BLE模块进行说明，NT指代可穿戴电子设备，CS指代云端服务器，AT指代辅助定位设备。
AT收到CS下发的NT进入指令；AT判断BLE是否属于开启状态；若BLE处于关闭状态，则AT开启BLE Master模式；若BLE处于开启状态，则AT将CS指令中的设备信息加入自身NT设备列表中；AT进行BLE轮询搜索设备；AT将NT设备列表和BLE扫描列表中的设备信息进行一一匹配；AT判断两个列表中是否有设备信息完全匹配；若发现有设备匹配，则将所有匹配的NT设备信息和自身位置信息一一拼装后向CS发送位置消息；AT判断NT设备列表中未搜索到的设备是否超出了搜索限定时间或次数；若发现有设备超出了搜索限定时间或次数，则AT从NT设备列表中删除该设备；AT判断NT设备列表是否为空；若NT设备列表为空，则AT关闭BLE。
