附图说明
为了更清楚地说明本发明实施例中的技术方案,下面将对现有技术和实施例中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

具体实施方式
本发明的核心是提供一种设备的功率控制方法、系统及装置,能够将设备中的RFFE模块的功率上限调整至适用在用户处于不同状态模式下的功率上限,避免RFFE模块的功率过大,进而避免了设备发热给用户带来的不适感以及辐射对用户的健康影响。
为使本发明实施例的目的、技术方案和优点更加清楚,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。
请参照图1,图1为本申请提供的一种设备的功率控制方法的流程图,包括:
S1:在确定用户携带设备时,确定用户当前所处的状态模式,状态模式至少包括睡眠模式和非睡眠模式;
S2:将设备中的RFFE模块的功率上限调整至状态模式对应的功率上限,睡眠模式对应的功率上限小于非睡眠模式对应的功率上限。
考虑到用户在不同状态下能够承受的设备发热量和辐射不同,例如,用户在睡眠状态时身体抵抗力会下降,用户的身体健康容易受到辐射的影响,此外,设备发热也会给用户带来不适感。为了避免设备发热给用户带来的不适感以及辐射对用户健康带来的影响,在用户携带了设备之后,确定用户当前所处的状态模式,而状态模式至少包括了睡眠模式和非睡眠模式,非睡眠模式可以但不限是表示用户正在通话时的通话模式或其他模式。
RFFE模块是设备中的核心模块之一,RFFE模块的功率与设备的发热量和辐射量呈正相关,通过调整RFFE模块的功率上限,以限制RFFE模块能够产生的最大功率,进而避免设备发热和辐射给用户带来的影响。具体的,不同的状态模式对应的功率上限不同,当状态模式是睡眠模式或者表示用户更容易受到发热和辐射的影响的状态时,对应的功率上限较低,当状态模式是非睡眠模式时,对应的功率上限相对于睡眠模式要高,以保证用户在正常使用时的体验。
综上所述,在确定用户携带了该设备时,首先获取该用户当前所处的状态模式,状态模式至少包括睡眠模式和非睡眠模式,然后将设备的功率上限调整至用户当前所处的状态模式对应的功率上限,而非睡眠模式下的功率上限大于睡眠模式下的功率上限,基于此,能够将设备的功率上限调整至适用在用户处于不同状态模式下的功率上限,避免设备产生过大的功率,进而避 免了设备发热给用户带来的不适感以及辐射对用户的健康影响。
在上述实施例的基础上:
作为一种优选的实施例,确定用户当前所处的状态模式,包括:
根据第一预设时间段内获取到的用户的心率值、血压值以及ECG信息中的一种或多种确定用户当前所处的状态模式。
为了确定用户当前所处的状态模式,本申请中,由于用户处于不同的状态模式时用户对应的心率值、血压值和ECG(electrocardiogram,心电图)信息不同,例如,用户在睡眠模式下的心率值和血压值较低,ECG的波形波动较小,而用户在运动模式下的心率值和血压值较低,ECG的波形波动较大,可知心率值、血压值和ECG信息与用户当前所处的状态模式之间有对应关系,在获取这些信息时,可以但不限于获取设备中的生物传感器检测到的这些信息。此外,第一预设时间段可以是以当前时间为结束时间点的一段时间,通过获取用户在第一预设时间段内的心率值、血压值和ECG信息,能够准确地确定出用户当前所处的状态模式。
作为一种优选的实施例,确定用户当前所处的状态模式,包括:
获取设备中的加速度传感器在第二预设时间段内检测到的加速度值;
根据加速度值确定用户的身体姿态;
根据身体姿态确定用户当前所处的状态模式。
为了确定用户当前所处的状态模式,本申请中,由于用户不同的动作和姿态对应的状态模式不同,例如,当用户将设备携带在手腕上时,用户在平躺时设备的位置变化范围较小,检测到的加速度值较低,而且加速度值的变化频率可能较低;而用户在正坐时设备的位置通常是水平变化的,检测到的加速度值的方向通常是近似平行于地面的,可知检测到的加速度值与用户当 前所处的状态模式之间有对应关系。基于此,可以通过第二预设时间段内检测到的加速度值来确定用户的身体姿态,再通过身体状态来确定状态模式,能够准确地确定出用户当前所处的状态模式。
此外,为了进一步的提高确定状态模式的准确率,可以先通过加速度值来确定用户的身体姿态,再获取用户的心率值、血压值和ECG信息,通过两者结合来确定用户当前所处的状态模式,请参照图2,图2为本申请提供的另一种设备的功率控制方法的流程图,例如,考虑到用户在睡眠时通常为平躺状态,所以当通过加速度值确定用户处于平躺模式时,再通过用户的心率值、血压值和ECG信息确定用户是否处于睡眠模式,可以避免用户处于非平躺模式时将用户的状态模式误判成睡眠模式,能够能准确地确定用户的状态模式。
作为一种优选的实施例,在确定用户当前所处的状态模式之前,还包括:
判断用户是否携带设备;
若携带设备,则进入确定用户当前所处的状态模式的步骤;
若未携带设备,则将设备中的RFFE模块的功率上限调整至第一预设功率上限,第一预设功率上限大于睡眠模式对应的功率上限。
为了保证用户的使用体验,本申请中,考虑到用户可能会将设备放在身边而并非携带在身上,此时由于设备与用户之间的距离较远,设备的发热以及辐射对用户的影响较小,所以当用户不携带该设备时,可以将设备中的RFFE模块的功率上限调高。具体的,根据设备中处理器的性能以实时或周期性地判断用户是否携带设备,例如,可以通过是否检测到用户体温、用户心率和用户动作等方式来判断用户是否携带设备,若携带则进行确定用户当前所处的状态模式的步骤,若未携带则将该设备的功率上限调整至第一预设功率上限,该第一预设功率上限大于睡眠模式对应的功率上限,由于用户不携带设备时设备的发热以及辐射对用户的影响较小,所以第一预设功率上限可以但不限于是RFFE模块的最大功率上限,以保证用户的使用体验。
作为一种优选的实施例,判断用户是否携带设备,包括:
判断第三预设时间段内获取到的心率值是否小于预设心率值;
若是,则判定用户未携带设备;
若否,则判定用户携带设备。
为了确定用户是否携带设备,本申请中,考虑到当用户未携带设备时,设备中的各种传感器或者模块无法检测到与用户相关的生物信息,例如无法获取到用户的心率值;而用户在携带设备时,可以但不限于通过设备中的生物传感器可以检测到用户的正常的心率值,基于此,可以预先设定一个预设心率值,当获取生物传感器在第三预设时间段内检测到的心率值时,判断获取到的心率值是否小于预设心率值,小于时则说明用户没有携带装备,否则则说明用户携带了设备。考虑到生物传感器检测到的心率值可能存在误差,例如,在用户未携带设备时,通常情况下获取到的心率值应为零,但此时可能会出现获取到的心率值为大于零的个位数的情况,为了避免将该种情况误判为用户携带了该装备,所以预设心率值可以是一个不为零的正整数,以准确地确定用户是否携带该设备。
作为一种优选的实施例,设备中的RFFE模块的功率上限为设备中的RFFE模块中的PA单元的功率上限。
PA(Power Amplifier,功率放大器)单元是RFFE模块中的核心单元之一,PA单元能够将设备需要发送的信号以及设备接收的信号进行放大,以便提高提高设备接收到的信号的质量,由于设备处于不同信号强度的环境下时,设备接收到的信号质量也不同,例如,当设备处于信号强度较弱的环境下时,设备接收到的信号质量较差,此时设备PA单元自身的工作功率会提高,以提高该信号的质量。考虑到若直接调整整个RFFE模块的功率上限,可能会影响到RFFE模块中其他单元的正常工作效率,为了避免影响到RFFE模块中的其他单元,所以可以指调整RFFE模块中的PA单元的功率上限,在实现控制设备产生的发热量和辐射量的同时,避免了RFFE模块中的其他单元受到影响。此外,除了PA单元的功率上限,还可以是RFFE模块中的Tuner(调 谐器)单元的功率上限或者RFFE模块中的其他与设备接收到的信号有关的单元。
作为一种优选的实施例,当非睡眠模式为通话模式时,将设备中的RFFE模块的功率上限调整至状态模式对应的功率上限,包括:
根据设备与用户的头部之间的距离调整设备中的RFFE模块的功率上限,功率上限与距离呈正相关。
为了降低用户在通话时设备产生的辐射对用户的影响,本申请中,考虑到用户在进行通话时,通常是将设备放至耳边进行通话,此时由于设备与用户的头部之间的距离较为接近,设备产生的辐射很容易对用户的健康造成影响,所以当用户处于通话状态时,根据设备本身与用户的头部之间的距离来调整设备的功率上限,设备本身离用户的头部越近时,设备的功率上限越低,设备本身离用户的头部越远时,设备的功率上限越高,以降低用户将设备放至耳边进行通话时设备产生的辐射对用户的影响。
作为一种优选的实施例,在根据设备与用户的头部之间的距离调整设备中的RFFE模块的功率上限之前,还包括:
基于设备中的加速度传感器判断用户是否有抬腕动作;
若是,则进入根据设备与用户的头部之间的距离调整设备中的RFFE模块的功率上限的步骤;
若否,则将设备中的RFFE模块的功率上限调整至第二预设功率上限,第二预设功率上限大于睡眠模式对应的功率上限。
为了确定用户是否将设备放至耳边进行通话,本申请中,考虑到在非通话模式下用户通常是将设备携带在手腕上或者存储在衣服中,当其他通讯设备向该设备发送通讯信号时,用户需要将其拿起进行通话,可见,在用户进行通话前需要先进行将设备拿起地动作,也即抬腕动作。基于此,请参照图3,图3为本申请提供的另一种设备的功率控制方法的流程图,当用户的当前 状态处于通话状态时,通过设备中的加速度传感器来判断用户是否有抬腕动作,具体的,可以周期性判断加速度传感器检测到的加速度值是否存在突然增加的情况并且突然增加的数值大于预设数值,存在时说明用户有抬腕动作,此时再根据设备本身与用户的头部之间的距离来调整设备中地RFFE模块的功率上限,不存在时,说明用户可能使用耳机或者使用免提进行通话,由于此时设备离用户较远,设备产生的热量和辐射对用户的影响较小,所以此时可以将设备中的RFFE模块的功率上限调整至第二预设上限。通过判断用户是否有抬腕动作,能够准确地确定用户是否将设备放至耳边进行通话。
请参照图4,图4为本申请提供的一种设备的功率控制装置的结构示意图,包括:
存储器21,用于存储计算机程序;
处理器22,用于执行计算机程序时实现如上述的设备的功率控制方法的步骤。
对于本申请提供的一种设备的功率控制装置的详细介绍,请参照上述一种设备的功率控制方法的实施例,本申请在此不再赘述。
请参照图5,图5为本申请提供的一种设备的结构示意图,包括RFFE模块31,还包括如上述的设备的功率控制装置32;
RFFE模块31与设备的功率控制装置32依次连接。
对于本申请提供的一种设备的详细介绍,请参照上述一种设备的功率控制方法的实施例,本申请在此不再赘述。
本说明书中各个实施例采用递进的方式描述,每个实施例重点说明的都 是与其他实施例的不同之处,各个实施例之间相同相似部分互相参见即可。对于实施例公开的装置而言,由于其与实施例公开的方法相对应,所以描述的比较简单,相关之处参见方法部分说明即可。
还需要说明的是,在本说明书中,诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来,而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
