具体实施方式
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，都属于本发明保护的范围。
实施例1：
本发明实施例提供了一种防丢失提醒方法，应用于防盗设备，如图1所示，所述方法包括以下步骤：
101、判断所述防盗设备与对端设备之间的连接断开前第一预设时长内的计步值是否大于预设值。
其中，所述第一预设时长为所述连接断开时刻之前的一段时间间隔。所述防盗设备可以是穿戴式防盗设备，例如蓝牙防盗手环。所述对端设备可以是手机。所述防盗设备与所述对端设备之间可以通过蓝牙进行连接，也可以通过其他信号进行连接。
需要说明的是，这里所说的连接断开前第一预设时长内，指的是，以连接断开时刻为起点，往前第一预设时长的时间段。例如， 所述第一预设时长为3秒，连接在第21秒断开，则判断从第18秒开始到第21秒开始这段时间内的计步值是否大于预设值。
所述防盗设备实时统计每个时刻前第一预设时长内的步数，以便获取所述连接断开前第一预设时长内的计步值。即针对任一时刻，统计从该时刻开始前第一预设时长内的步数。
若第一预设时长为3s，则防盗设备实时统计每个时刻之前3秒内的步数。这样假设，第21s信号断开连接，防盗设备则获取从第18s到第21s的计步值；第30s信号断开连接，防盗设备则获取从第27s到第30s的计步值。
在步骤101之前，所述防盗设备还需要获取从所述连接断开时刻之前第一预设时长内的计步值。所述防盗设备通过内部的加速度传感器可以检测到用户运动，从而可以实时记录从每一个时刻往前第一预设时长内的步数，就可以获取到所述连接断开时刻开始往前第一预设时长内的步数。
需要说明的是，第一预设时长可以是该防盗设备的使用者进行设定的，在此不作限定。通常，信号连接断开可能是由于对端设备远离防盗设备造成的，也可能是由于使用者手臂摆动导致信道质量变差而造成的。因此，在信号连接断开后立即震动提醒可能是误提醒。而进一步判断信号断开连接前一段时间内的计步值与预设值之间的大小，可以更准确地判断信号连接断开是否是由于对端设备远离防盗设备而造成的。
102、若所述计步值大于所述预设值，则判断所述防盗设备与所述对端设备之间通信信号的信号质量值序列，在所述连接断开前第一预设时长内是否呈递减趋势。
这里，所述信号质量值是对所述信号的RSSI(Received signal strength indication，接收信号强度指示)值进行防脉冲干扰平均滤波处理之后获得的。理论上，信号的RSSI值随着距离成指数规律的递减，由于无线信道中的随机因素对信号的干扰，可能导致获取的RSSI值并不准确。因此需要对信号的RSSI值进行防脉冲干扰平均滤波处理，获得准确的RSSI值之后，在进行后续判断。需要 说明的是，这里所述的准确的RSSI值即本发明实施例所述的信号质量值序列。当然如果信道质量很好，对信号的干扰可以忽略不计，则可以直接将获取到的信号的RSSI值作为本发明所述的信号质量值。
所述防盗设备实时统计每个时刻前第一预设时长内的信号质量值序列变化趋势。例如，所述第一预设时长为3秒，连接在第21秒断开，则统计从第18秒开始到第21秒开始这段时间内的信号质量值序列，假设信号质量值序列每0.5秒获取一次，则从第18秒至第21秒内获取包含6个信号质量值的信号质量值序列，则需要判断从第18秒至第21秒的6个信号质量值序列的变化趋势。
103、若所述信号质量值序列在所述连接断开前第一预设时长内呈递减趋势，则进行报警。
报警可以为防盗设备蜂鸣，或LED灯闪烁灯方式。
在信号连接断开之后，所述计步值大于预设值，则表明所述对端设备可能远离所述防盗设备了。只有在确定所述信号的信号质量值序列在信号断开连接前第一预设时长内递减，才能肯定所述对端设备确实是远离所述防盗设备了。如果信号质量值序列在信号断开连接前第一预设时长内不是递减的，则表明所述对端设备并没有远离所述防盗设备。
这样，由于所述信号质量值序列在在信号断开连接前第一预设时长内呈递减趋势，所述对端设备远离所述防盗设备，则表明所述对端设备很有可能被盗取或者丢失了，则立即进行报警，提醒使用者所述对端设备可能丢失。
另外，如果信号的信号质量值序列在所述连接断开前第一预设时长内不是递减的，则表明所述对端设备并没有远离所述防盗设备，通常，对端设备没有远离所述防盗设备时，且所述连接在断开第二预设时长后自动恢复。这样，就不需要进行报警。
如果信号的信号质量值序列在所述连接断开连接前第一预设时长内不是递减的，且所述连接断开第二预设时长后未恢复，还是要进行报警，提醒使用者所述对端设备可能丢失。如果所述连接断 开第二预设时长后恢复，则表明信号连接断开可能是由于使用者手臂摆动造成的，这种情况下信号可在一段时间内自动回复连接，因此不必进行报警提醒使用者。
另外，如果所述防盗设备判断所述计步值小于所述预设值，且未在所述连接在断开第二预设时长后恢复，则进行报警。如果所述防盗设备判断所述计步值小于所述预设值，且所述连接在断开第二预设时长后恢复，则不启动报警。
优选地，在本发明的优选实施例中，所述判断所述防盗设备与对端设备之间的连接断开前第一预设时长内的计步值是否大于预设值之前，所述方法还包括：
所述防盗设备实时统计每个时刻前第一预设时长内的步数，以便获取所述连接断开前第一预设时长内的计步值。即针对任一时刻，统计从该时刻往前第一预设时长内的步数。
若第一预设时长为3s，则防盗设备实时统计每个时刻之前3秒内的步数。这样假设，第21s信号断开连接，防盗设备则获取从第18s到第21s的计步值。第30s信号断开连接，防盗设备则获取从第27s到第30s的计步值。需要说明的是，所述预设值为所述防盗设备与所述对端设备之间的安全距离的对应的步数，所述第二预设时长为所述防盗设备与所述对端设备在安全距离内、所述信号恢复连接的时长。其中，第一预设时长，第二预设时长，预设值均可为所述防盗设备的使用者自行设置的，或是出厂前由厂家设置，再此不做限定。
当然，在检测到所述防盗设备与对端设备之间的信号连接断开之后，所述防盗设备可以直接进行报警，这也是现有技术中的方案。本发明实施例对为所述防盗设备设置有两个模式，一种是检测到蓝牙连接断开就立即震动警报。另一个模式则是进行本实施例的步骤101-103。这两个模式可以由所述防盗设备的使用者来选择设置。在此不作限定。
本发明实施例提供的防丢失提醒方法，防盗设备在连接断开时，立即判断从所述连接断开时刻之前第一预设时长内的计步值。 若确定所述计步值大于预设值，则判断所述防盗设备与所述对端设备之间的通信信号的信号强度值序列所述第一预设时长内是否呈递减趋势，若是，则立即进行报警。若判断所述计步值大于预设值、所述信号强度值序列在所述第一预设时长内未呈递减趋势，且所述连接在断开第二预设时长后未恢复，则立即进行报警。现有技术中，防盗设备在信号断开连接之后，立即进行报警。实际上，会存在对端设备和防盗设备之间的距离没有超出预设距离(例如：防盗设备与对端设备之间有遮挡物，导致信道环境变差)，信号连接也会断开的情况，这样，防盗设备出现误振动提醒。本发明实施例提供的防丢失提醒方法，可以提高蓝牙防丢失提醒的准确性，避免非丢失情况下的误振动提醒。
实施例2：
本发明实施例提供了一种防丢失提醒方法，如图2所示，所述方法包括以下步骤：
201、防盗设备检测到自身与对端设备之间的连接断开，则判断所述连接断开前第一预设时长内的计步值是否大于预设值。
其中，所述第一预设时长为所述连接断开时刻之前的一个时间间隔。所述预设值由所述防盗设备的使用者设置或是出厂时由厂家设置，在此不做限定。
通常，信号连接断开可能是由于对端设备远离防盗设备造成的，也可能是由于使用者手臂摆动导致信道质量变差而造成的。因此，在信号连接断开后立即震动提醒可能是误提醒。所以还需要进一步判断，提高震动提醒的准确性。进一步判断信号连接断开前一段时间的计步值与预设值之间的大小，就可以更准确地判断信号连接断开是否是由于对端设备远离防盗设备而造成的。如果所述计步值大于预设值，则表明对端设备有可能远离防盗设备了，如果所述计步值不大于预设值，则表明对端设备并没有远离防盗设备，是由使用者手臂摆动造成信号断开连接。
若所述连接断开前所述第一预设时长内的计步值大于预设值，则进行步骤202；若所述连接断开前所述第一预设时长内的计步值 不大于预设值，则进行步骤204。
202、判断所述防盗设备与所述对端设备之间通信信号的信号质量值序列，在所述连接断开前所述第一预设时长内是否呈递减趋势。
若所述信号质量值序列在所述连接断开前第一预设时长内呈递减趋势，则进行203；若所述信号质量值序列在所述连接断开前第一预设时长内未呈递减趋势，则进行步骤204。
203、进行报警。
由于所述信号质量值序列在所述连接断开前第一预设时长内递减，则表明所述对端设备与所述防盗设备在所述连接断开前第一预设时长内的距离在递增，由于本发明实施例中所述的防盗设备通常为穿戴式设备，因此表明对端设备已经远离使用者，很有可能已经丢失，则应该立即进行报警，提醒使用者。
204、判断所述连接在断开第二预设时长后是否恢复。
这里的前提是所述计步值不大于预设值，或者所述信号质量值序列在所述连接断开前第一预设时长内未呈递减趋势，这两种情况都表明对端设备并没有远离防盗设备。通常，对端设备没有远离防盗设备时，由于使用者手臂摆动造成信号断开连接，信号会在很短的时间内恢复连接。因此需要在连接断开第二预设时长后检测所述信号是否恢复连接。
如果所述连接恢复，则不需要报警，如果所述连接未恢复连接，则需要震动报警。即，所述连接恢复时进行步骤205；若所述信号未恢复连接时进行步骤203。
205、不启动震动报警。
此时，信号连接恢复正常。
本发明实施例提供的防丢失提醒方法，防盗设备在连接断开时，立即判断从所述连接断开时刻之前第一预设时长内的计步值。若确定所述计步值大于预设值，则判断所述防盗设备与所述对端设 备之间的通信信号的信号强度值，在所述连接断开前第一预设时长内是否呈递减趋势。若是，则立即进行报警。若判断所述计步值大于预设值、所述信号强度值在所述连接断开前第一预设时长内未呈递减趋势，且所述连接在断开第二预设时长后未恢复，则立即进行报警。现有技术中，防盗设备在信号断开连接之后，立即进行报警。实际上，会存在对端设备和防盗设备之间的距离没有超出预设距离(例如：防盗设备与对端设备之间有遮挡物，导致信道环境变差)，信号连接也会断开的情况，这样，防盗设备出现误振动提醒。本发明实施例提供的防丢失提醒方法，可以提高蓝牙防丢失提醒的准确性，避免非丢失情况下的误振动提醒。
实施例3：
本发明实施例提供了一种防丢失提醒方法。其中，防盗设备与对端设备之间通过蓝牙建立连接，第一预设时长等于5s，第二预设时长等于2s，预设值等于5，所述防盗设备为蓝牙手环，所述对端设备为手机。如图3所示，所述方法包括：
301、蓝牙手环与手机之间的蓝牙连接正常。
302、蓝牙手环检测到其与手机之间的蓝牙连接断开。
303、模式判定。
需要说明的是，本发明实施例提供的方法，蓝牙手环有两种模式，模式一是蓝牙断开立即进行报警；模式二是进行多重判断，提供进行报警的准确性。
如果用户设置的是模式一，则进行步骤304；如果用户设置的是模式二，则进行步骤305。
304、进行报警。
305、判断蓝牙连接断开前5秒内的计步值是否大于5。
这里所说的蓝牙连接断开前5s内指的是，以蓝牙连接断开时刻为起点，往前5s内时间段。例如，蓝牙连接在第21秒断开，则判断从第16秒开始到第21秒开始这段时间内的计步值是否大于5。
若大于，则进行步骤306；若不大于，则进行步骤307。
306、判断该蓝牙信号的信号质量值序列在断开前5秒内是否递减。
若是，则进行步骤304；若不是，则进行步骤307。
307、从蓝牙断开时刻等待2秒后，检测蓝牙连接是否恢复。
若是，则进行301；若不是，则进行步骤304。
本发明实施例提供的防丢失提醒方法，通过用户的选择配置，可以使手环工作在传统模式一下，也可以工作在模式二。采用二级判断机制，首先计步值进行一级判断，该判断可以覆盖大多数误丢失判断场景，在第一级判断步数大于一定值后，才进行二级判断，如果信号质量值序列不符合递减规律，即认为属于误丢失判断，不启动报警。另外，确定手机未远离手环之后，延长一定时间后判断蓝牙连接是否恢复，确定蓝牙连接未恢复后才启动报警，从而实现避免手环频繁误振动的现象出现。提升蓝牙防丢判断的精度技术方案可以有效的提高手环蓝牙防丢判断的精度，避免由于手臂摆动等因素引起的非丢失情况下的误振动报警，提升产品的用户体验。
