常见的追踪器可以吸附在小孩、宠物、老人、行李等物品上，然后通过智能手机设置定位物品的安全距离，当物品超出安全距离时，手机收到报警提示，但是现有追踪器是有一定的定位距离限制的，超过安全距离后无法精确定位物品位置，导致很难追回物品。

基于上述防丢追踪方法及追踪系统，标签贴在物品上，当物品超过了安全距离时，标签中的无线通信模块将定位模块定位的标签的当前的位置信息发送给服务器，以供用户追踪物品。
附图说明
图1为防丢追踪方法的流程图。
图2为标签的功能模块图。
图3为防丢追踪系统的功能模块图。
具体实施方式
下面将结合本发明实施方式中的附图，对实施方式中的技术方案进行清楚、完整的描述。
本实施方式中，防丢追踪方法用于追踪物品，在待跟踪的物品贴有标签。标签中包含无线通讯模块、无线通信模块以及定位模块，标签通过无线通讯模块与报警终端连接；标签通过该无线通信模块与服务器连接；标签通过定位模块来获取当前的位置信息。
请参看图1，防丢追踪方法包括步骤：
步骤S101，标签与报警终端建立无线网络连接。
本实施方式中，可以有多个标签同时与报警终端建立无线网络连接，也可以只有一个标签与报警终端建立无线网络连接。当有若干个标签同时与报警终端建立无线网络连接时，每个标签都有唯一标识码。本实施方式中唯一标识码为标签的MAC地址。无线网络连接的方式可以为WIFI连接也可以为蓝牙连接，当标签与报警终端之间是WIFI连接时，标签将无线通信模块连接的GPRS网络或者3G/4G网络转化为WIFI信号以供其与报警终端建立WIFI连接，本实施方式中优选标签与报警终端建立蓝牙连接。
标签与报警终端建立蓝牙连接的过程为：报警终端通过USB接口插入装有驱动程序的上位机；上位机识别报警终端；若识别通过，报警终端则具有了通信能力，即上位机控制报警终端进入搜索状态并读取报警终端的蓝牙MAC地址，并通过报警终端的蓝牙MAC地址读取标签蓝牙MAC地址进行配对，使报警终端与标签建立蓝牙连接。
本实施方式中优选报警终端为手环，便于用户随时携带。
步骤S102，标签或者报警终端判断该无线网络连接是否中断，若标签与报警终端之间的无线网络连接中断，执行步骤S103；若标签与报警终端之间无线网络连接未中断，执行步骤S112。
由于无论标签与报警终端之间的无线网络连接是WIFI连接还是蓝牙连接，标签与报警终端之间的连接具有距离限制，超过该距离后，标签与报警终端之间的连接将中断，本实施方式中，蓝牙连接的极限距离为3米。
步骤S103，报警终端发出警报。
报警终端上设有音频模块、振动模块以及LED灯，报警终端所发出警报是以声音、震动以及LED灯亮的形式发出。
步骤S104，标签或者报警终端判断预设时间内标签与报警终端间的无线网络连接是否重新建立，若没有重新建立无线网络连接，执行步骤S105；若重新建立无线网络连接，执行步骤S111。
本实施方式中设置预设时间为10秒，当标签或者报警终端检测到标签与报警终端中断无线网络连接后且10秒内未恢复该无线网络连接时，执行步骤S105。
步骤S105，标签启动无线通信模块。
无线通信模块为标签利用3G/4G网络或者利用GPRS网络与服务器通信。本实施方式中，优选无线通信模块为GPRS无线通信模块，GPRS无线通信模块是用于通过GPRS网络进行数据收发，因此标签可通过GPRS网络与服务器交互。
步骤S106，标签按照预设频率获取当前的位置信息。
标签上的定位模块用于获取标签当前的位置信息，本实施方式中，定位模块采用GPS技术或者基站定位技术来定位。当使用基站定位时，至少需要三个基站位置才可推算出标签位置。
步骤S107，标签按照预设频率发送当前的位置信息给服务器以供用户查看。
标签可通过无线通信模块发送标签的位置信息给服务器，预设频率可设定为5秒/次、10秒/次、20秒/次等以保证服务器能够掌握标签的最新位置。此外，还可同时发送物品的状态信息给服务器。当步骤S102中检测到标签与报警终端之间的无线网络连接中断时，发送给服务器的状态信息为物品丢失信息。本实施方式中，标签通过无线通信模块发送给服务器的位置信息以及状态信息以格式指令的形式发送，例如标签蓝牙MAC地址，时间，经度，纬度，状态，其中经度和纬度表示标签的位置。
步骤S108，标签或者报警终端判断标签与报警终端间的无线网络连接是否重新建立，若没有重新建立无线网络连接，执行步骤S106；若重新建立了无线网络连接，执行步骤S109。
报警终端与标签之间没有重新建立网络连接，则表示物品还未追回，标签将继续发送位置信息以及物品丢失信息给服务器。
步骤S109，标签通过无线通信模块发送当前的位置信息以及物品已追回信息给服务器。
当物品已追回，标签将当前状态以及位置信息发送给服务器，以供服务器更新。
步骤S110，标签关闭无线通信模块。
步骤S111，报警终端停止报警。
步骤S112，根据光敏技术判断标签是否被损坏。标签上设有光敏传感器，当标签被撬开或者撕开时，光敏传感器可检测到标签被损坏。
步骤S113，报警终端发出警报。
步骤S114，标签启动无线通信模块以及定位模块的工作。
步骤S115，标签按照预设频率获取当前的位置信息。具体地，标签利用定位模块来获取当前的位置信息。
步骤S116，标签按照预设频率发送当前的位置信息以及标签损坏信息给服务器。
当标签损坏时，服务器接收并更新该标签的位置信息以及状态信息后，用户可根据该位置信息判断物品是否安全以及修复标签。
步骤S117，标签利用光敏技术标签判断其是否已修复。
步骤S118，标签发送当前的位置信息以及标签已修复信息给服务器。
步骤S119，标签关闭无线通信模块。需要说明的是，当步骤S119执行完毕后，执行步骤S111。
还需说明的是，上述防丢追踪方法中，省去步骤S103、步骤S113以及步骤S111后也是一个完整的追踪方法，此追踪方法中不限制报警终端的报警功能，报警终端作为检测标签是否在安全范围的一个终端设备。
基于上述防丢追踪方法，即使物品丢失后，服务器也能通过标签获取到物品的最新位置信息以供用户跟踪追回物品，此外，该追踪方法还能监控到标签的状态，以防止有人故意撬开标签来破坏追踪。
相较于上述方案，进一步地，标签和手环上还设有LED灯，当标签和手环上的电量低于预设值时，标签和手环上的LED灯将闪烁以提供用户充电。追踪方法还包括标签判断其电量是否低于预设值，当标签的电量低于预设值时，标签还将按照预设规则降低向服务器发送位置信息以及状态信息的频率。预设规则为电量降低时，发送频率降低。本实施方式中，随着电量的消耗，发送频率逐渐衰减为5秒/次、10秒/次、1分/次、3分/次以及5分/次。该方式可有效的延长标签电量的使用时间，防止标签耗电过快导致还未追回物品时，标签就没有电量了即无法定位物品位置。
