Description
本发明涉及通信领域，尤其涉及一种解决蓝牙低功耗遥控器按键丢失的方法和蓝牙低功耗遥控器。
红外遥控器经过多年的发展，技术已经成熟，且实现成本低，因此红外遥控器得到了广泛应用，但是由于红外遥控器与被控设备必须在视距范围内，因此在某些应用场景下不适宜使用红外遥控器，如体积很小的互联网播放器经常被用户放到电视机后面，遥控器信号被电视机隔开，红外遥控器无法正常控制互联网播放器。因此，蓝牙低功耗(Bluetooth low energy，BLT)遥控器(以下简称蓝牙遥控器)以其低功耗和不受限制的优先性得到发展。
为了降低蓝牙遥控器的功耗，在用户不使用蓝牙遥控器的情况下，该蓝牙遥控器通常关闭蓝牙链路，进入待机状态。当进入待机状态后，根据蓝牙遥控器的不同设置，有两种情况：第一种情况是该蓝牙遥控器接收到的用户的第一次按键操作只用于与被控设备建立蓝牙链路，然后第二次按键操作及后续的按键操作用于控制被控设备；第二种情况是该蓝牙遥控器接收到的用户的第一次按键操作既用于与被控设备建立蓝牙链路，又用于控制被控设备，具体的，蓝牙遥控器接收到用户的第一次按键操作后，先建立蓝牙链路，在蓝牙链路建立完成后，再将该用户的第一次按键操作通过建立好的蓝牙链路发送给该被控设备。
在第一种情况中，由于第一次按键操作只用于与被控设备建立蓝牙链路，这样会使用户认为该第一次按键操作没有响应，从而判断该蓝牙遥控器失灵；在第二种情况中，用户的第一次按键操作对应的按键键值需要等待蓝牙链路建立完成之后才会能发送给受控设备，即受控设备被用户的第一次按键操作控制相对于用户的第一次按键操作会有延迟，同样会使用户认为该第一次按键操作没有响应，从而判断该蓝牙遥控器失灵，降低了用户的体验，影响了蓝牙遥控器的人机交互的性能。

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。
请参阅图1，本发明实施例中解决蓝牙低功耗遥控器按键丢失的方法一个实施例包括：
101、BLT遥控器检测用户是否进入所述BLT遥控器的预定距离内；
BLT遥控器运行时，检测用户是否进入该BLT遥控器的预定距离内。
该预定距离为预先设定，其大小可以出厂预置，也可以由用户自定义设置，还可以与检测的具体技术相关，此处不作限定。
可以理解的是，若用户进入该BLT遥控器的预定距离内，则可以判定用户有使用该BLT遥控器的可能。
102、当确定用户进入所述BLT遥控器的预定距离内，且所述BLT遥控器与被控设备之间的蓝牙链路为断开状态时，所述BLT遥控器建立与所述被控设备之间的蓝牙链路；
当BLT遥控器确定用户进入所述BLT遥控器的预定距离内，且该BLT遥控器与被控设备之间的蓝牙链路为断开状态时，该BLT遥控器建立与该被控设备之间的蓝牙链路。
需要说明的是，该BLT遥控器一段时间不使用时，会断开与被控设备之间的蓝牙链路，可以进入休眠模式以节省功耗，此时BLT遥控器与被控设备之间的蓝牙链路为断开状态，当BLT遥控器确定用户进入该BLT遥控器的预定距离内时，表示用户有使用该BLT遥控器的可能，则可以在用户使用该BLT遥控器之前，检测到用户有使用该BLT遥控器的可能时，提前从休眠模式唤醒，建立与该被控设备之间的蓝牙链路。
可以理解的是，BLT遥控器一般与被控设备一一对应，因此双方均可以存储有对方的蓝牙标识，建立蓝牙链路时，可以不再需要进行蓝牙标识的查找，
配对等步骤，BLT遥控器可以直接和与其对应的被控设备建立蓝牙链路。
103、当所述BLT遥控器接收到用户的按键操作时，所述BLT遥控器通过建立完成的所述蓝牙链路，将接收到的按键操作确定的按键键值发送到所述被控设备。
BLT遥控器建立与被控设备之间的蓝牙链路后，当接收到用户的按键操作时，通过建立完成的该蓝牙链路，将接收到的按键操作确定的按键键值发送到该被控设备。
需要说明的是，BLT遥控器上有很多按键，每个按键都有相应的按键键值，用户对该BLT遥控器的每次按键操作都会确定一个按键键值，例如，当用户在BLT遥控器上按下数字键3时，该BLT遥控器接收到用户按下数字键3的按键操作，该BLT遥控器可以确定数字键3的按键键值，然后将该数字键3对应的按键键值发送给受控设备；再如，当用户在BLT遥控器上按下开机键时，该BLT遥控器接收到用户按下开机键的按键操作，该BLT遥控器确定开机键的按键键值，将该开机键对应的按键键值发送给受控设备，用户对BLT遥控器上存在的其他按键的按键操作，蓝牙遥控器也会确定相应的按键键值，再将确定的按键键值发送给受控设备，此处不作赘述。
该BLT遥控器接收到的用户的按键操作可以为用户拿到该BLT遥控器后的第一次按键操作，由于此前该BLT遥控器已经建立好了与被控设备之间的蓝牙链路，因此BLT遥控器能直接将接收到的用户的第一次按键操作确定的按键键值发送到被控设备，不会出现延迟或丢失。
本发明实施例中，BLT遥控器检测用户是否进入该BLT遥控器的预定距离内，当确定用户进入该BLT遥控器的预定距离内，且该BLT遥控器与被控设备之间的蓝牙链路为断开状态时，该BLT遥控器建立与该被控设备之间的蓝牙链路，即在检测到用户进入BLT遥控器的预定距离内时，就确定用户有使用该BLT遥控器的趋势，提前与被控设备之间建立好蓝牙链路，作好发送用户的按键操作确定的按键键值的准备，不再需要等待接收到用户的第一个按键操作再建立蓝牙链路，当接收到用户的按键操作时，该BLT通过已经建立好的蓝牙链路，立即发送接收到的用户的按键操作确定的按键键值到被控设备中，由于是采用已经建立好的蓝牙链路进行发送，则即使接收到的是用户的第
一次按键操作，也不会再出现延迟或丢失该第一次按键操作的情况，解决了用户的第一次按键操作延迟或丢失的问题，能够及时将用户的第一次按键操作确定的按键键值发送到被控设备，提高了蓝牙遥控器的人机交互性能。
上面实施例中，BLT遥控器检测是否有人体接近到所述BLT遥控器的预定距离内，在实际应用中，其可以采用多种方式实现，下面对本发明实施例中解决按键丢失的方法进行具体描述，请参阅图2，本发明实施例中解决蓝牙低功耗遥控器按键丢失的方法另一个实施例包括：
201、BLT遥控器中的接近传感器检测探测范围内磁场是否有变化；
当检测到的探测范围内磁场发生变化时，确定用户进入该BLT遥控器的预定距离内，触发步骤202；
当检测到探测范围内磁场没有发生变化时，确定用户不进入该BLT遥控器的预定距离内，继续执行步骤201，直到第二预定时长内检测到探测范围内磁场均没有发生变化，则触发步骤204。
具体的，用户接近BLT遥控器时会引起BLT遥控器附近磁场发生变化，而接近传感器可以检测到该接近传感器附近的磁场变化，具体的工作原理为现有技术，此处不作赘述。
本步骤中，通过BLT遥控器中内置的接近传感器对探测范围内磁场的变化来确定用户是否进入该BLT遥控器的预置距离内，在实际应用中，还可以有其他的判定用户是否进入该BLT遥控器的预置距离内的方法：
可选的，作为本发明实施例中解决蓝牙低功耗遥控器按键丢失的方法另一个实施例，该BLT遥控器可以检测该BLT遥控器中电容传感器容值的变化幅度；当检测到容值的变化幅度大于预置变化幅度时，确定用户进入该BLT遥控器的预定距离内。可以理解的是，用户接近BLT遥控器时，会引起其中电容传感器容值的变化。可以理解的是，此处除了使用电容传感器，还可以使用其他类型的接触传感器，此处不作限定。
可选的，作为本发明实施例中解决蓝牙低功耗遥控器按键丢失的方法另一个实施例，该BLT遥控器中的红外传感器可以检测探测范围内红外光谱是否发生变化；当检测到探测范围内红外光谱发生变化时，确定用户进入该BLT遥控器的预定距离内。需要说明的是，用户接近BLT遥控器时，会引起BLT
遥控器周围红外光谱的变化。
可选的，作为本发明实施例中解决蓝牙低功耗遥控器按键丢失的方法另一个实施例，该BLT遥控器中的振动传感器可以检测该BLT遥控器周边的振动幅度；当检测到的振动幅度超过预置振动幅度时，确定有人体接近到所述BLT遥控器的预定距离内。
具体的，因为用户接近BLT遥控器时，接近过程中的步行会引起地面的振动，也可能会带动BLT遥控器周边空气的振动，人手靠近BLT遥控器的过程中，也可能会引起BLT遥控器此时的载体的振动，例如桌子，沙发等，BLT遥控器周边这些物体的振动能被BLT遥控器中的振动传感器检测到，当BLT遥控器检测到周边物体振动的振动幅度大于预置振动幅度时，则确定用户进入该BLT遥控器的预定距离内。需要说明的是，振动传感器检测周边物体的振动幅度通过现有技术实现，此处不作赘述。可以理解的是，虽然检测到周边物体振动的振动幅度大于预置振动幅度时，除了可能是用户进入该BLT遥控器的预定距离内，还有其他的可能，比如地震等，但是在实际应用中，从最大可能性考虑，还是可以选择这种方式来确定用户进入该BLT遥控器的预定距离内。
可以理解的是，该振动传感器可以为主动式，也可以为被动式，若该振动传感器为主动式，则该检测过程可以为持续不断进行，也可以按照预置间隔周期进行，此处不作限定；若该振动传感器为被动式，则该检测过程可以一直持续进行，且对功耗消耗较低。
还可以有很多其它的判定是否有人体接近该BLT遥控器的预定距离内的方法，此处不作限定。
202、当确定用户进入所述BLT遥控器的预定距离内，且所述BLT遥控器与被控设备之间的蓝牙链路为断开状态时，所述BLT遥控器建立与所述被控设备之间的蓝牙链路；
203、当所述BLT遥控器接收到用户的按键操作时，所述BLT遥控器通过建立完成的所述蓝牙链路，将接收到的按键操作确定的按键键值发送到所述被控设备；
步骤202和203与步骤102和103类似，此处不作赘述。
204、当在第二预定时长内没有检测到用户进入所述BLT遥控器的预定距离内时，所述BLT遥控器关闭建立完成的所述蓝牙链路。
当在第二预定时长内均没有检测到用户进入该BLT遥控器的预定距离内时，该BLT遥控器关闭该建立完成的蓝牙链路。
可以理解的是，第二预定时长内没有检测到用户进入该BLT遥控器的预定距离内，则表示用户可能暂时不会使用该BLT遥控器，而此时BLT遥控器已与被控设备建立了蓝牙链路，为了节省功耗，该BLT遥控器可以关闭该蓝牙链路，进入休眠模式。可以理解的是，关闭该蓝牙链路后，或进入休眠模式时，可以继续执行步骤201。
可选的，作为本发明实施例中解决蓝牙低功耗遥控器按键丢失的方法另一个实施例，该解决蓝牙低功耗遥控器按键丢失的方法还可以包括：当在第一预定时长内没有检测到用户的按键操作时，该BLT遥控器关闭建立完成的蓝牙链路。可以理解的是，若在第一预定时长内没有检测到用户的按键操作，也可以判定用户暂时不会使用该BLT遥控器，可以关闭建立好的蓝牙链路节省功耗。
可以理解的是，上述在第一预定时长内没有检测到用户的按键操作时，关闭建立好的蓝牙链路和在第二预定时长内没有检测到用户进入该BLT遥控器的预定距离内时，关闭建立好的蓝牙链路，可以同时使用，也可以分别使用其中任一个，此处不作限定。
本发明实施例中，可以通过BLT遥控器中的各种传感器判定用户是否进入BLT遥控器的预定范围内，实现了对用户使用该BLT遥控器的趋势的判定，提高了终端的人机交互性能。进一步的，当第二预定时长内均没有检测到用户进入该BLT遥控器的预定距离时，关闭该蓝牙链路，节省了该BLT遥控器的功耗，提高了BLT遥控器的续航时间。
为便于理解，下面以一具体应用场景对本发明实施例中解决按键丢失的方法进行具体描述：
客厅中没有人，BLT遥控器放置在沙发上，处于休眠模式(与被控设备的蓝牙链路处于断开状态)；
用户回到家，进入客厅，坐到沙发上，用户坐到沙发上时引起的沙发的振
动被BLT遥控器中的振动传感器检测到；
BLT遥控器确定用户在预定范围内，有使用该BLT遥控器的可能；
BLT遥控器退出休眠模式，建立与被控设备的蓝牙链路；
用户在沙发上坐好之后，拿起BLT遥控器，此时BLT遥控器与被控设备之间的蓝牙链路已经提前建立完成；
用户在BLT遥控器上按下开机键，BLT遥控器将该开机键对应的按键键值传输给被控的电视机，使电视机开机。
下面对本发明实施例中的蓝牙低功耗遥控器进行描述，请参阅图3，本发明实施例中蓝牙低功耗遥控器一个实施例包括：

发送模块303，用于当接收到用户的按键操作时，通过建立完成的所述蓝牙链路，将接收到的所述按键操作确定的按键键值发送到所述被控设备。
本发明实施例中，检测模块301检测用户是否进入该BLT遥控器的预定距离内，当确定用户进入该BLT遥控器的预定距离内，且该BLT遥控器与被控设备之间的蓝牙链路为断开状态时，建立模块302建立与该被控设备之间的蓝牙链路，即在检测到用户进入BLT遥控器的预定距离内时，就确定用户有使用该BLT遥控器的趋势，提前与被控设备之间建立好蓝牙链路，作好发送用户的按键操作确定的按键键值的准备，不再需要等待接收到用户的第一个按键操作再建立蓝牙链路，当接收到用户的按键操作时，该BLT通过已经建立好的蓝牙链路，发送模块303立即发送接收到的用户的按键操作确定的按键键值到被控设备中，由于是采用已经建立好的蓝牙链路进行发送，则即使接收到的是用户的第一次按键操作，也不会再出现延迟或丢失该第一次按键操作的情况，解决了用户的第一次按键操作延迟或丢失的问题，能够及时将用户的第一次按键操作确定的按键键值发送到被控设备，提高了蓝牙遥控器的人机交互性能。

可以理解的是，上述各实施例的检测模块中的各种检测单元及相应的确定模块可以单独存在在一个BLT遥控器中，也可以相互组合放在同一个BLT遥控器中，此处不作限定。
本发明实施例中，可以通过检测模块301中的各种检测单元判定用户是否进入BLT遥控器的预定范围内，实现了对用户使用该BLT遥控器的趋势的判定，提高了终端的人机交互性能。进一步的，当第二预定时长内均没有检测到用户进入该BLT遥控器的预定距离时，第二关闭模块402关闭该蓝牙链路，节省了该BLT遥控器的功耗，提高了BLT遥控器的续航时间。
为了便于理解上述实施例，下面以上述BLT遥控器各个模块在一个具体应用场景中的交互过程进行说明：
客厅中没有人，BLT遥控器放置在沙发上，处于休眠模式(与被控设备的蓝牙链路处于断开状态)；
用户回到家，进入客厅，坐到沙发上，用户坐到沙发上时引起的沙发的振动被BLT遥控器中的振动检测单元409检测到；
第四确定模块410确定用户在预定范围内，有使用该BLT遥控器的可能；
BLT遥控器退出休眠模式，建立模块302建立与被控设备的蓝牙链路；
用户在沙发上坐好之后，拿起BLT遥控器，此时BLT遥控器与被控设备之间的蓝牙链路已经提前建立完成；
用户在BLT遥控器上按下开机键，发送模块303将该开机键对应的按键键值传输给被控的电视机，使电视机开机。
