开关控制单元111，用于控制定位模块和长距离无线通信模块的启用与不启用，如果判断防丢失系统用随身设备不在监护设备的监控范围内，则开关控制单元启用定位模块和长距离无线通信模块以将位置信息上报给防丢失系统用服务器；如果判断随身设备在监护设备的监控范围内，则不启用定位模块和长距离无线通信模块。
具体地，如果防丢失系统用随身设备在防丢失系统用监控设备的监控范围内，则定位模块不启用，即处于关闭状态或飞行模式或睡眠模式或休眠模式，长距离无线通信模块不启用，即处于关闭状态(断电模式)或飞行模式或睡眠模式或休眠模式，其中关闭状态指的是定位模块或长距离无线通信模块处于断电模式，无电源供给，飞行模式指的是定位模块或长距离无线通信模块不进行定位信号或长距离无线通信信号的发送和接收，睡眠模式或休眠模式指的是定位模块或长距离无线通信模块处于低功耗状态。
当前述短距离无线通信基于的技术为蓝牙技术，则短距离无线通信信号为蓝牙信号。在其他的实施例中，当前述短距离无线通信基于的技术为Wi-Fi 技术时，则短距离无线通信信号为Wi-Fi信号；当前述短距离无线通信基于的技术为ZigBee技术时，则短距离无线通信信号为ZigBee信号；当前述短距离无线通信基于的技术为RFID技术时，则短距离无线通信信号为RFID信号。
在实际中，防丢失系统用随身设备中的短距离无线通信模块和判断控制模块为主控，其一直处于工作状态；定位模块和长距离无线通信模块为从设备，在判断控制模块的控制下启用或不启用，即防丢失系统用随身设备不在防丢失系统用监控设备的监控范围内时，其需要获得随身设备的位置信息，并通过与防丢失系统用服务器的长距离无线通信将位置信息发送给监护设备，则开启定位模块和长距离无线通信模块；防丢失系统用随身设备在防丢失系统用监控设备的监控范围内时，其不需要获得随身设备的位置信息，以及与防丢失系统用服务器的长距离无线通信，则关闭定位模块和长距离无线通信模块。从而实现短距离无线通信模块和判断控制模块与定位模块和长距离无线通信模块的分时工作，大大降低系统功耗，可以实现比普通产品更持久的使用时间，增强了用户体验。
综上所述，本发明一实施例提供的防丢失系统用随身设备，通过根据防丢失系统用监护设备发送的短距离无线通信信号，判断随防丢失系统用身设备是否在防丢失系统用监控设备的监控范围内，如果在防丢失系统用监控设备的监控范围内，则不启用其定位模块和长距离无线通信模块，如果不在防丢失系统用监控设备的监控范围内，则启用其定位模块以及长距离无线通信模块，实现了长距离无线通信模块和定位模块的分时工作，避免了防丢失系统用随身设备的长距离无线通信模块和定位模块时时刻刻在工作，同时由于短距离无线通信信号具有辐射小、功耗低、一定(相同)电池容量下续航能力强，长距离无线通信信号具有辐射高，功耗高，一定(相同)电池容量下续航能力弱的特性，从而降低了防丢失系统用随身设备的功耗，延长了防丢失系统用随身设备的续航时间，同时极大降低了防丢失系统用随身设备的长距离无线通信信号对携带者的辐射。
结合上述实施例提供的内容，下述实施例中只是对监控范围判断单元110的具体判断过程进行说明。
监控范围判断单元110的具体判断过程可以如下：
如果防丢失系统用随身设备未接收到防丢失系统用监控设备发送的短距离无线通信信号，则判断防丢失系统用随身设备不在防丢失系统用监控设备的监控范围内；如果防丢失系统用随身设备接收到防丢失系统用监控设备发送的短距离无线通信信号，则判断防丢失系统用随身设备在防丢失系统用监控设备的监控范围内。
例如：在下述实施例中以蓝牙技术为例对短距离无线通信技术进行说明，但短距离无线通信技术并不限于蓝牙技术，也可以为任何能够实现短距离无线通信功能的其他技术，比如Wi-Fi技术、ZigBee技术、RFID技术等。
当与防丢失系统用随身设备进行绑定的防丢失系统用监控设备为一个时，防丢失系统用随身设备未接收到该一个防丢失系统用监控设备发送的蓝牙信号，则判断其不在防丢失系统用监控设备的监控范围内，否则判断其在防丢失系统用监控设备的监控范围内。
当与防丢失系统用随身设备进行绑定的防丢失系统用监控设备为N个时，防丢失系统用随身设备可以是未接收到N个监控设备中的当前监控设备(即与防丢失系统用随身设备建立短距离无线通信连接的监控设备)发送的蓝牙信号，则判断其不在防丢失系统用监控设备的监控范围内，还可以是未接收到N个监控设备中任一监控设备发送的蓝牙信号(即未接收到当前监控设备的蓝牙信号，还未接收到由N个监控设备组成的监护组中其他监控设备的蓝牙信号)，则判断其不在防丢失系统用监控设备的监控范围内，如果能接收到N个监控设备中至少一个监控设备发送的蓝牙信号，则判断其在防丢失系统用监控设备的监控范围内。
监控范围判断单元110的具体判断过程也可以如下：
如果防丢失系统用随身设备未接收到防丢失系统用监控设备发送的短距离无线通信信号，则判断防丢失系统用随身设备不在防丢失系统用监控设备的监控范围内；
如果防丢失系统用随身设备接收到的蓝牙信号的信号强度低于预设的信号强度阈值，则防丢失系统用随身设备判断其不在防丢失系统用监控设备的监控范围内，如果防丢失系统用随身设备接收到的蓝牙信号的强度不低于预设的信号强度阈值，则判断其在防丢失系统用监控设备的监控范围内。
具体地，在下述实施例中以蓝牙技术为例对短距离无线通信技术进行说 明，但短距离无线通信技术并不限于蓝牙技术，也可以为任何能够实现短距离无线通信功能的其他技术，比如Wi-Fi技术、ZigBee技术、RFID技术等。
当与防丢失系统用随身设备进行绑定的防丢失系统用监控设备为一个时，如果防丢失系统用随身设备接收到的蓝牙信号的信号强度低于预设的信号强度阈值，则防丢失系统用随身设备判断其不在该防丢失系统用监控设备的监控范围内，否则判断其在该防丢失系统用监控设备的监控范围内。
例如：将信号强度阈值预设为-85dBm，防丢失系统用监控设备发送的蓝牙信号的信号强度为-80dBm，如果防丢失系统用随身设备接收到的蓝牙信号的信号强度为-83dBm，由于防丢失系统用随身设备接收到的蓝牙信号的信号强度为-83dBm大于预设的信号强度阈值-85dBm，则防丢失系统用随身设备判断其在防丢失系统用监控设备的监控范围内。如果防丢失系统用随身设备接收到的蓝牙信号的信号强度为-87dBm，由于防丢失系统用随身设备接收到的蓝牙信号的信号强度-87dBm小于预设的信号强度阈值-85dBm，则防丢失系统用随身设备判断其不在防丢失系统用监控设备的监控范围内。实际应用中，预设的信号强度阈值可以为-80dBm，还可以为其他值，例如-75dBm、-70dBm等，本实施例不对预设的信号强度阈值进行具体限定。
当与防丢失系统用随身设备进行绑定的防丢失系统用监控设备为N个时，此时N个监控设备组成为监护组，如果防丢失系统用随身设备接收到的M个蓝牙信号的信号强度均低于预设的信号强度阈值，则防丢失系统用随身设备判断其不在该N个监控设备的监控范围内，否则判断其在该N个监控设备的监控范围内，N为大于等于2的整数，M为小于等于N且大于等于1的整数。本发明涉及的信号强度阈值可以通过在防丢失系统监护设备上设置监控范围，然后发送给防丢失系统服务器，然后由防丢失系统用服务器发送给防丢失系统用随身设备。还可以是预先存储在防丢失系统用随身设备中。
监控范围判断单元110的具体判断过程还可以如下：
防丢失系统用监控设备发送的短距离无线通信信号包括第一区域方向信号和第二区域方向信号，如果防丢失系统用随身设备读取到的短距离无线通信信号依次为第一区域方向信号和第二区域方向信号，则判断防丢失系统用随身设备处在防丢失系统用监控设备的监控范围内，反之，如果防丢失系统用随身设备读取到的短距离无线通信信号依次为第二区域方向信号和第一区 域方向信号，则判断防丢失系统用随身设备不在防丢失系统用监控设备的监控范围内，其中，第一区域方向信号和第二区域方向信号的覆盖区域不重合。
具体地，在下述实施例中以RFID技术为例对短距离无线通信技术进行说明，但短距离无线通信技术并不限于RFID技术，也可以为任何能够实现短距离无线通信功能的其他技术，比如Wi-Fi技术、ZigBee技术、RFID技术等。
由于前述短距离无线通信基于的技术为RFID技术，则短距离无线通信信号为RFID信号，该RFID信号包括：第一区域方向信号和第二区域方向信号，第一区域方向信号和第二区域方向信号各自辐射的区域不重合。则防丢失系统用随身设备根据防丢失系统用监控设备发送的RFID信号，判断防丢失系统用随身设备是否在监控设备的监控范围内。
例如，以防丢失系统用监控设备的监控范围为学校为例，防丢失系统用监控设备的第一区域方向信号向学校内部发射，即第一区域方向信号指的是往校内区域发射的信号，防丢失系统用监控设备的第二区域方向信号向学校外部发射，即第二区域方向信号指的是往校外区域发射的信号，如果防丢失系统用随身设备先接收到第一区域方向信号，后接收到第二区域方向信号，即防丢失系统用随身设备由校内区域进入校外区域，则确定防丢失系统用随身设备离开学校，判断其不在防丢失系统用监控设备的监控范围内；如果防丢失系统用随身设备先接收到第二区域方向信号，后接收到第一区域方向信号，即防丢失系统用随身设备由校外区域进入校内区域，则确定防丢失系统用随身设备进入学校，是安全的，判断其在防丢失系统用监控设备的监控范围内。此时，防丢失系统用监控设备可以为具有定向RFID射频信号的打卡设备，对应地，防丢失系统用随身设备可以为RFID标签。
结合前述实施例提供的内容，参见图4，本发明实施例还提供了一种防丢失系统，其包括：
防丢失系统用随身设备1，其具体结构可参见前述实施例中的防丢失系统用随身设备，此处不再一一赘述；
防丢失系统用监控设备2，具备用于与防丢失系统用随身设备1建立短距离无线通信连接的短距离无线通信模块；
防丢失系统用监护设备3，具备用于与防丢失系统的服务器4建立长距 离无线通信连接的长距离无线通信模块；
防丢失系统用服务器4，具有长距离无线通信功能，能够与防丢失系统用随身设备1和防丢失系统用监护设备3建立长距离无线通信连接；
其中，当防丢失系统用随身设备在防丢失系统用监控设备的监控范围内时，防丢失系统用随身设备的定位模块和长距离无线通信模块不启用；当防丢失系统用随身设备不在防丢失系统用监控设备的监控范围内时，防丢失系统用随身设备的定位模块和长距离无线通信模块启用以将防丢失系统用随身设备的位置信息上报给防丢失系统用服务器，使得防丢失系统用服务器将位置信息通知给防丢失系统用监护设备。
防丢失系统用服务器将位置信息发送给防丢失系统用监护设备的方式可以是防丢失系统用服务器获得位置信息后自动发送给防丢失系统用监护设备，还可以是响应防丢失系统用监护设备的位置请求后，将位置信息发送给防丢失系统用监护设备，本实施例不对此进行限定。防丢失系统用监护设备显示位置信息的形式可以是以标记在电子地图上对应位置的图标或亮点等，还可以是以文字的形式，本实施例不对此进行限定。其中，位置信息是表示随身设备所在空间位置的信息
防丢失系统用监控设备的数量为多个或一个，当防丢失系统用监控设备的数量为多个时，多个防丢失系统用监控设备共同组成一个监护组，防丢失系统用随身设备基于短距离无线通信判断防丢失系统用随身设备在监护组中的一个防丢失系统用监控设备的监控范围内时，则防丢失系统用随身设备不启用其定位模块和长距离无线通信模块；防丢失系统用随身设备基于短距离无线通信判断随身设备不在监护组中的任一个监控设备的监控范围内时，随身设备启用其定位功能和远程无线通信功能。
在实际中，防丢失系统用监控设备可以为具有短距离无线通信功能的设备，当短距离无线通信为蓝牙时，防丢失系统用监控设备可以为蓝牙挂绳或蓝牙贴膜等，防丢失系统用监护设备可以为具有长距离无线通信功能的手机，需要说明的是：防丢失系统用监控设备和防丢失系统用监护设备可以为一体结构，例如既具有长距离无线通信功能，又具有短距离无线通信功能的手机，所述防丢失系统用监护设备和所述防丢失系统用监控设备还可以绑定为一个设备，例如防丢失监控设备为蓝牙挂绳/蓝牙贴膜，防丢失系统用监护设备未 不具有蓝牙功能的手机，通过绑定，将该手机与蓝牙挂绳/蓝牙贴膜视为一个设备。当短距离无线通信为RFID时，防丢失系统用监控设备可以为具有RFID功能和/或能发射定向信号的打卡设备或阅读器，对应地，防丢失系统用随身设备可以为RFID标签。为了使得防丢失系统用随身设备的应用范围广，其可以同时具有RFID技术和蓝牙技术。服务器为设置于基站、互联网等中的服务器。随身设备中蓝牙芯片可以采用商购的蓝牙4.0芯片，在其他实施例中，还可以选用其他芯片。
下面以将本发明的防丢失系统应用于针对幼儿园小朋友进行的防丢失处理的情况为例详细进行说明。
多个具有蓝牙功能的手机可以看做是多个将防丢失系统用监控设备和防丢失系统用监护设备一体化的终端机，所述多个手机中的每一个手机都可以看做是一个监护人，这多个手机共同构成监护人组。例如在一个三代同堂的家庭中，孩子的父母和爷爷奶奶外公外婆都可以是孩子的监护人，各人所持有的手机通过蓝牙配对设置(与孩子所佩戴的儿童腕表配对)都可以作为孩子的监护人，所有的监护人共同构成监护人组，该监护人组列表信息通过服务器传输并存储至腕表端，配对连接时进行鉴权，非监护人列表拒绝配对，进一步增强了腕表端用户的私密性与安全性。
所述防丢失系统用随身设备为带有蓝牙和数字通讯定位功能的儿童腕表，该儿童腕表的外观与普通腕表没有太大差异，越普通的儿童腕表越不易让人察觉其防丢失功能。现有的防丢器例如手表、手环等智能设备是以定位功能为主，主要是以移动运营商基站定位，WIFI定位，以及AGPS辅助GPS卫星定位来实现其功能，但是待机通话功能以及GPS定位功能功耗高，加上电池容量的瓶颈，导致智能定位设备的使用时间短，一般使用一天或者两天就要充电，影响用户体验，以及在没有信号的地方无法进行定位和传输位置信息。另外，由于定位手表和手环全部基于手机模块(该手机模块用于实现通信功能)加GPS模块(该GPS模块用于实现定位功能)，通信功能实时开启，长时间存在辐射，对儿童的健康尤其是年幼儿童的健康发展不利。而本发明的儿童腕表至少包括一个主芯片(在本实施例中使用MT6260)和一个蓝牙芯片(在本实施例中使用CC2540)，通过蓝牙芯片和主芯片上设置的通信定位模块，实现了以蓝牙芯片为主控，数字通讯定位为辅的功能，也就是 说，本发明的儿童腕表至少包括短距离无线通信模块，用于与防丢失系统用监控设备建立短距离无线通信连接；定位模块，用于定位得出所述防丢失系统用随身设备的位置信息；长距离无线通信模块，用于与防丢失系统的服务器建立长距离无线通信连接；和判断控制模块，用于根据防丢失系统用监控设备发送的短距离无线通信信号判断防丢失系统用随身设备是否在防丢失系统用监控设备的监控范围内，如果防丢失系统用随身设备在防丢失系统用监控设备的监控范围内，则不启用定位模块和长距离无线通信模块，如果防丢失系统用随身设备不在防丢失系统用监控设备的监控范围内，则启用定位模块和长距离无线通信模块以将位置信息上报给防丢失系统用服务器。通常情况下，以短距离无线通信模块即蓝牙模块为主控，也就是当孩子处于监护人组的范围内时，腕表的定位模块即gps、agps(通讯功能)不启用，孩子一天中绝大部时间是处于监护中，腕表的长距离无线通信模块即通信功能是关闭的，基本没有辐射。只有当孩子丢失时，也就是脱离了监护人组的范围时才会由判断控制模块自动切换开启定位功能和长距离无线通信功能，启动GPS/WIFI/基站定位等功能进行定位，并将监护人组和孩子的位置上报给服务器。蓝牙模块具有开关控制单元，该开关控制单元的输出端与通讯定位模块的开关机键/通信定位模块的电源开关连接，用于控制通信定位模块的开关机键或通信定位模块的电源开或关。在实际中，该开关控制单元的输出端若输出的电平是高电平时，通信定位模块开启；若输出的电平是低电平时，通信定位模块关闭，在其他的实施方式中，还可以是该开关控制单元的输出端若输出的电平是低电平时，通信定位模块开启；若输出的电平是高电平时，通信定位模块关闭。本实施例不对此进行限定。
另外，本实施例的针对幼儿园适龄儿童的防丢系统，进一步将幼儿园作为了监护人之一，其技术上是通过追加辅助终端设备(打卡设备)来实现的，该辅助终端设备例如打卡设备并不具备蓝牙功能，但是具有定向RFID射频信号，即有源发射，通过设置两个这样的打卡设备，并且一个打卡设备的信号向幼儿园内部发射，另一个打卡设备的信号向幼儿园外部发射，将向幼儿园外部发射的信号定为1(相当于第一方向)，将向幼儿园内部发射的信号定为2(相当于第二方向)，则接收到信号1→2为进入幼儿园，接收到信号2→1则为离开幼儿园。在这种情况下，就可以将幼儿园看作一个监护人，本 发明的儿童腕表可以记录RFID读卡器信息，当孩子处于幼儿园的有效信号范围内时，儿童腕表上的RFID标签被打卡设备读取到，同时RFID标签也读取RFID打卡设备的ID，也就是说，既可以实现考勤记录功能，也可以做判断儿童腕表进出入幼儿园的依据，当儿童进入幼儿园则幼儿园成为有效监护人，即可以判断儿童与幼儿园这一监护人已连接配对成功；当儿童离开幼儿园则为离开了幼儿园这一监护人的有效范围。另外，对于如何使幼儿园这样较大面积的固定设施作为监护人之一，除了以上所述的利用打卡设备的方法以外，也可以采用例如追加作为信号靶点的蓝牙设备等各种方法。由于考虑到蓝牙信号的匹配需要一定时间即存在延时，为了准确判断出孩子是进入幼儿园还是离开幼儿园，更优选采用本实施例的RFID打卡设备。
另外，原则上来说，一个儿童腕表只允许有一个主监护人和多个辅助监护人。在首次使用时，主监护人可以用自己的智能手机下载一个应用程序APP，通过APP设置好监护人组信息，上传到服务器，再由服务器下发给儿童腕表，儿童腕表根据监护人组的列表进行区分，防止非监护人对监护人进行配对或获取腕表的相关信息。
另外，在监护人的手机不具备本发明的实施例所要求的蓝牙技术的情况下，还可以通过购置例如蓝牙挂件或蓝牙贴膜等来与手机绑定，也就是外置蓝牙功能，使该手机能够作为本发明的终端设备使用。具体的绑定方法例如可以设置如下：开启蓝牙挂件或蓝牙贴膜，打开手机蓝牙功能，选择同意绑定后，扫描蓝牙挂件或蓝牙贴膜的二维码或者输入对应编号完成绑定。绑定完成后，手机端将绑定结果告知服务器并由服务器存储手机与蓝牙挂件或蓝牙贴膜的绑定信息即可。
其中，在该防丢失系统中进一步包括蓝牙防丢监控、电子围栏(安全区域)、搜索定位和联合搜救四大功能。完成监护人组的设置并与儿童腕表进行蓝牙配对以后，即可开启家人账号监护组防走失及搜索定位功能。本发明中监护人组包括多个家长端和幼儿园端，其中幼儿园端设置有打卡设备，儿童在入园和出园时腕表内置的RFID会与打卡设备连接，自动识别。
防丢监控功能是指通过多个监护人组成监护人组，通过手机端实时监控孩子的位置。当儿童腕表与监护人手机蓝牙配对成功时由所配对的手机定时向服务器上传监护人手机/儿童腕表位置信息，当孩子在监护人组范围内时， 儿童腕表的gps、agps(通讯功能)不启用。一旦孩子超出了监护组最后监护人的监护范围，也就是说，当孩子脱离了一个监护人的范围时会自动进行扫描，如果能够扫描并配对上监护人组里的其他监护人，则可以认为孩子是安全的，只有当孩子脱离了前一个监护人的范围却无法找到下一个其他监护人进行配对时，才判断为超出了监护组最后监护人的监护范围，前一个监护人自动被判定为最后监护人，服务器会进行SOS报警，例如首先向最后监护人发送走失提醒或者电话通知，当没收到该最后监护人的回信或应答时再向监护人组的其他监护人依次(可根据优先级别或者之前配对的先后顺序等)发送走失提醒或者电话通知；当监护人组发生蓝牙配对失败并且经过上述SOS报警一定时间后仍然没有找到孩子则视为丢失，儿童腕表自动启用通信定位模块，并且开启基站定位，WIFI定位，agps/GPS进行混合定位，实现高精度定位，并上报监护人组和孩子的位置信息给服务器，当孩子超出监护人组的监护范围时，将作出以下措施：1.进行上述SOS报警，并且服务器会保留相关报警信息；2.允许开启背景音监听和环境图片拍照；3.开启腕表端混合定位功能(WIFI、LBS和AGPS/GPS)，混合定位精准，同时可降低功耗。监护人可以通过智能手机上安装的APP向服务器请求位置信息，可返回孩子位置信息并在地图上显示。服务器端会记录和下发孩子的移动轨迹，出现意外情况可以追踪到最后位置。
另外，可以通过APP对孩子的轨迹进行设置，超过一定范围才自动报警告知监护人，实现电子围栏(安全区域报警)功能。电子围栏可以自由设置，当小孩离开监护组的监护范围(认为是丢失)，开启定位，比对是否超过设定的安全区域，超过则报警，没超过安全区域则不会报警，减少家长的恐慌。如小孩与家长在小区里，虽然超过防丢的范围，可能还在视线区域，或者小孩未走出小区，很容易找到小孩，这时就不需要给家长报警。
搜索定位功能是指监护人可以通过手机app获取孩子的位置或移动轨迹。儿童腕表蓝牙开启后，通过蓝牙配对到监护人手机后由当前配对的手机向服务器上报腕表/监护人信息。儿童腕表与任意一个监护人手机蓝牙配对成功时，监护人组中的任意监护人都可以通过手机端app获得孩子位置信息(就是当前监护人的位置信息)。当监护人组的全部监护人手机与儿童腕表蓝牙配对失败时，儿童腕表启动混合定位并向服务器上报腕表/监护人信息，此时， 任意监护人通过手机端APP向服务器查询儿童腕表位置，服务器都将获取腕表端的定位信息，并向监护人发送腕表位置。
联合搜救功能是儿童腕表处于特殊状态时(即孩子不在监护组范围(已丢失)且设备处于无网络(无GSM，无GPS，无WIFI)的危险状态时)，儿童腕表将通过蓝牙模块主动发出呼救广播，当装有本发明的防丢失系统用手机端APP的手机路过并接收到呼救广播(通过后台驻留服务)时，自动记录接收时间以及自己的位置信息，并向服务器上报，由服务器进行相关处理，并通知该儿童腕表的相关监护人。当腕表端无法进行蓝牙配对及混合定位时，进入主动呼救状态，启动蓝牙发送广播，周边装有APP的手机设备或其它注册设备接收到呼救广播，可获得丢失儿童腕表的ID、位置和时间等信息，并上报给服务器，服务器将信息发送到家长手机端。
综上所述，本发明实施例提供的方法，随身设备根据与其绑定的监护设备发送的短距离无线通信信号，判断随身设备是否在监护设备的监控范围内，如果在监护设备的监控范围内，则不启用其定位功能和长距离无线通信功能，如果不在监护设备的监控范围内，则启用随身设备的定位功能以及长距离无线通信功能，实现了长距离无线通信功能和定位功能的分时工作，避免了随身设备的长距离无线通信功能和定位功能时时刻刻在工作，同时由于短距离无线通信信号具有辐射小、功耗低、一定(相同)电池容量下续航能力强，长距离无线通信信号具有辐射高，功耗高，一定(相同)电池容量下续航能力弱的特性，从而降低了随身设备的功耗，延长了随身设备的续航时间，同时极大降低了随身设备的长距离无线通信信号对携带者的辐射。
以幼儿为例，在正常使用该随身设备时，该随身设备实际的待机时间(正常使用下时间)一般为30天左右，在现有的电池技术条件下根本性的解决了类似可穿戴智能设备的续航瓶颈。由于该随身设备只有当其不在监控设备的监控范围内时，才开启随身设备的定位功能，避免了时时刻刻都在远程无线信号辐射下。由于该随身设备只有当其不在监控设备的监控范围内时，才开启长距离无线通信，以便于对随身设备所述的周围环境进行监听，从而对随身设备的佩戴者(被监护人)的隐私加强了保护。
需要说明的是：上述实施例提供的防丢失系统用随身设备以及防丢失系统在进行防丢失时，仅以上述各功能模块的划分进行举例说明，实际应用中， 可以根据需要而将上述功能分配由不同的功能模块完成，即将设备的内部结构划分成不同的功能模块，以完成以上描述的全部或者部分功能。
由技术常识可知，本发明可以通过其它的不脱离其精神实质或必要特征的实施方案来实现。因此，上述公开的实施方案，就各方面而言，都只是举例说明，并不是仅有的。所有在本发明范围内或在等同于本发明的范围内的改变均被本发明包含。
