监护人终端21、22……2N，同时与各个可穿戴终端11、12……1M进行蓝牙连接，用于获取与各个可穿戴终端11、12……1M之间的蓝牙连接信息，并上传到后台服务器3；其中，所述蓝牙连接信息包括监护人终端21、22……2N与各个可穿戴终端11、12……1M之间的蓝牙连接距离。
具体的，监护人终端21、22……2N可以是监护人的智能手机、平板电脑等等电子设备，在电子设备上安装本系统相应的应用程序APP，每一个监护人终端2j（1≤j≤N，j为正整数）上也具有蓝牙模块，同时与各个可穿戴终端11、12……1M进行蓝牙连接，例如，系统中有3个可穿戴终端，则蓝牙模块同时与这3个可穿戴终端进行蓝牙连接，与其它监护人终端共同构成一个监护网络群。
在外出游玩时，多个监护人同时携带多个儿童和/或老人，所述多个可穿戴终端11、12……1M和所述多个监护人终端21、22……2N构成一个由蓝牙连接组成的监护网络群之后，监护人终端21、22……2N还用于获取与各个可穿戴终端11、12……1M之间的蓝牙连接信息，并上传到后台服务器3；其中，所述蓝牙连接信息包括监护人终端与各个可穿戴终端之间的蓝牙连接距离。例如，系统中有3个可穿戴终端11、12、13和3个监护人终端21、22、23，则监护人终端21会分别获取与可穿戴终端11、12、13之间的蓝牙连接距离，例如1米、2米、2米，并上传到后台服务器3；监护人终端22会分别获取与可穿戴终端11、12、13之间的蓝牙连接距离，例如1米、1米、1米，并上传到后台服务器3；监护人终端23会分别获取与可穿戴终端11、12、13之间的蓝牙连接距离，例如1米、2米、1米，并上传到后台服务器3。
后台服务器3，用于根据所述蓝牙连接信息判断是否存在一个或多个可穿戴终端11、12……1M与所有监护人终端21、22……2N之间的蓝牙连接距离超过预设安全阈值，若是，则向所有监护人终端21、22……2N推送报警信息，所述报警信息用于提示有儿童和/或老人可能走失。
具体的，后台服务器3在获取到所有可穿戴终端11、12……1M与所有监护人终端21、22……2N之间的蓝牙连接距离之后进行实时保存，同时判断是否存在一个或多个可穿戴终端1i与所有监护人终端21、22……2N之间的蓝牙连接距离超过预设安全阈值，若是，则说明该可穿戴终端1i对应的儿童和/或老人已经走失，则向所有监护人终端21、22……2N推送报警信息，提示有儿童和/或老人可能走失，从而实现了短距离的监控，第一时间做到了被监护人走失风险的发现。
作为一可选实施例，所述监护人终端，还用于接收用户设置所述预设安全阈值。例如，用户可以在监护人终端的应用程序APP设置所述预设安全阈值为20米，当其中有一个可穿戴终端与所有监护人终端之间的蓝牙连接距离都超过20米时，说明该可穿戴终端对应的儿童和/或老人可能走失，则向所有监护人终端推送报警信息，提示有儿童和/或老人可能走失。
本发明实施例的技术方案，在实现短距离监控的同时，通过多对多的蓝牙短距离监控策略，可以有效提高监控的范围和效率，降低走失风险。
在上述实施例实现多对多蓝牙短距离监控策略的基础上，本实施例还可以实现寻人最优路径策略。具体的，所述后台服务器3，还用于在向所有监护人终端21、22……2N推送报警信息之后，根据各个监护人终端21、22……2N和走失的儿童和/或老人的可穿戴终端1i的实时GPS数据计算出所有监护人和该走失的儿童和/或老人的各自的第一最短路径信息，并将各自对应的第一最短路径信息推送给所有的监护人终端21、22……2N。
具体的，一旦有儿童和/或老人与所有监护人的实时距离都超出了预设安全阈值，例如20米，后台服务器3第一时间会推送报警信息给所有的监护人。如图2所示，可穿戴终端，还包括呼叫模块116，用于实现与各个监护人终端之间的通话，此时监护人可以利用监护人终端的应用程序APP通过连接可穿戴终端的呼叫模块实现与该儿童和/或老人的通话，可以叫被儿童和/或老人优先站在原地不动，等待监护人过去寻找，同时系统会根据该儿童和/或老人身上的可穿戴终端和所有监护人的监护人终端实时上传的GPS位置信息，计算出所有监护人和该儿童和/或老人的各自第一最短路径信息，并将各自对应的第一最短路径信息推送给所有的监护人终端，监护人可以在监护人终端的应用程序APP上实时查看该儿童和/或老人的可穿戴终端的位置信息和相应的最短路径信息来进行寻找。
作为一可选实施例，所述可穿戴终端，还包括方向传感器和高度传感器；其中：方向传感器，用于获取与各个监护人终端之间的方向信息，并上传到后台服务器；高度传感器，用于获取可穿戴终端的当前楼层位置信息，并上传到后台服务器。所述后台服务器，还用于根据所述方向信息、所述当前楼层位置信息、所述实时GPS数据计算出所有监护人和该走失的儿童和/或老人的各自的第二最短路径信息，并将各自对应的第二最短路径信息推送给所有的监护人终端。
具体的，例如，如图2所示，其中一个可穿戴终端11包括方向传感器114和高度传感器115；方向传感器114，用于获取与各个监护人终端21、22……2N之间的方向信息，并上传到后台服务器3；高度传感器115，用于获取可穿戴终端11、12……1M的当前楼层位置信息，并上传到后台服务器3。对于大型商场等室内场所，针对GPS定位技术无法有效识别彼此相对的空间位置这一问题，本实施例可以设置开启室内监控模式，通过在可穿戴终端中增加方向传感器和高度传感器来采集双方的相对方向和高度信息，并同时结合GPS位置信息，由后台服务器3根据GPS位置信息给出基于平面位置的最优寻找路径，同时根据双方相对的方向和高度信息给出基于空间位置的寻找指引，从而提高寻找被监护人的效率和精准度。
本发明实施例的技术方案，通过在可穿戴终端上增加方向传感器和高度传感器，可以有效推断出走失的被监护人相对于监护人的方向和楼层位置，从而弥补了GPS技术在室内空间中无法精准定位的缺点。
在上述实施例实现多对多蓝牙短距离监控策略、寻人最优路径策略的基础上，本实施例还可以实现减少风险误报策略。具体的，所述可穿戴终端，还包括温度传感器，用于实时采集当前温度信息，并上传到后台服务器；所述后台服务器，还用于判断所述当前温度信息是否低于预设温度阈值，且持续超过预设时间阈值，若是，则向所有监护人终端提示该儿童和/或老人可能将可穿戴终端摘下。所述可穿戴终端，还包括加速度传感器，用于实时采集当前运动信息，并上传到后台服务器；所述后台服务器，还用于当所述当前温度信息低于预设温度阈值，且持续超过预设时间阈值时，如果所述可穿戴终端处于运动状态，则不向所有监护人终端提示。
具体的，例如，如图2所示，其中一个可穿戴终端11包括温度传感器117和加速度传感器118；温度传感器117，用于实时采集当前温度信息，并上传到后台服务器3；加速度传感器118，用于实时采集当前运动信息，并上传到后台服务器3。针对防止丢失设备存在风险误报和预警准确度不高的问题，本实施例提出一种减少风险误报的策略，通过在可穿戴终端上增加温度传感器和加速度传感器来采集人体温度和运动状态数据并上传给后台服务器，后台服务器会实时监控采集到的人体温度来判断该被监护人是否有将可穿戴终端摘下或丢失的风险，只有当没有采集到人体温度的持续时间超过一定的时间阈值，才断定该被监护人已经将可穿戴设备摘下，并通知所有的监护人，可以有效减少被监护人偶尔短时间摘下可穿戴终端而导致的风险误报。假设在没有收集到温度信息的情况下，后台系统也会实时计算该可穿戴终端的加速度信息，当判断该被监护人满足一定的移动状态并在有效的监控范围内，系统也不会进行风险预警，可以有效避免被监护人把可穿戴终端放在包里或口袋里而产生的误报情况，从而有效的提高了风险预警的准确率。
本发明实施例的技术方案，可以有效识别出可穿戴终端是否有在被监护人身上正常工作，减少风险误报率，提高风险预警的精准度。
本发明实施例的技术方案，通过采用基于低功耗蓝牙连接的密接技术，实现儿童及老人身上的可穿戴终端与监护人的互联，达到短距离和多对多的监控效果，在有效地扩大监控范围的同时可以做到第一时间预警风险。同时，通过在可穿戴终端上增加方向传感器和高度传感器，可以有效推断出走失的被监护人相对于监护人的方向和楼层位置，从而弥补了GPS技术在室内空间中无法精准定位的缺点。进一步的，通过在可穿戴终端上增加温度传感器和加速度传感器，可以有效识别出可穿戴终端是否有在被监护人身上正常工作，减少风险误报率，提高风险预警的精准度。
注意，上述仅为本发明的较佳实施例及所运用技术原理。本领域技术人员会理解，本发明不限于这里所述的特定实施例，对本领域技术人员来说能够进行各种明显的变化、重新调整和替代而不会脱离本发明的保护范围。因此，虽然通过以上实施例对本发明进行了较为详细的说明，但是本发明不仅仅限于以上实施例，在不脱离本发明构思的情况下，还可以包括更多其他等效实施例，而本发明的范围由所附的权利要求范围决定。
