背景技术
智能手表和手环之类的可穿戴设备主要优势在于监测用户健康，比如，利用手环监测运动步数、心率、睡眠指数等，这些智能穿戴设备集成了很多的传感器，用来获取佩戴者的体征数据，记录健康状况。由于脉搏或者心率是生命体征的重要参数之一，所以心率测量已成为智能穿戴设备必备的一个功能。
目前，可穿戴设备的心率测量主要通过光电容积脉搏波描记法(photoelectric plethysmography，PPG)。PPG是借光电手段在活体组织中检测血液容积变化的一种无创检测方法，是利用光测量脉搏的一种技术。即利用光电传感器检测经过人体血液和组织吸收后的反射光强度的不同，描记出血液流量在心动周期内的变化，从得到的脉搏波形中计算出心率。如图1所示的光电传感器的结构，光电传感器可以包括发射器、接收器等。其中，发射器可以是发光二极管、红外发射二极管等，接收器可以包括光电晶体管等。当发射器发出的光照透过皮肤组织然后再反射到接收器时光照存在一定程度的衰减。通过光照的变化即可容积脉搏血流的变化。
然而，对智能手表和手环之类的可穿戴设备来说，不规范的佩戴方式会影响心率信号的测量，比如不完全贴合导致的漏光、手臂的摆动以及智能手表或手环在皮肤上的轻微移动等，都会影响测量的心率信号。智能手表或手环佩戴得过紧、手臂抬高和握拳等也会影响血液循环，同样可能影响到心率信号。

具体实施方式
下面将结合附图对本申请实施例中的技术方案进行描述。
本申请中涉及的可穿戴设备可以是智能手表、智能手环、智能眼镜、智能安全帽、智能手套、智能跑鞋等等。上述可穿戴设备可以检测佩戴者的生理参数，且佩戴是松紧程度会影响可穿戴设备测量参数的准确性。在本申请实施例中，以可穿戴设备为智能手表为例，采用智能手表测量佩戴者的心率进行说明。
图2示例性示出了现有技术中智能手表佩戴要求的示意图。如图2中的左图所示，当手表佩戴的太松时，由于手表与手腕之间有缝隙会使手表在手腕上滑动，导致传感器无法读取心率或者无法准确读取心率，如图3示出的手表佩戴太松时测得的PPG信号，可以看出PPG信号发生了突变，此时用户应该试着将手表的表带收紧一点。图2中的右图示例性示出了手表正确的佩戴方式，手表应该舒适的贴服于手腕上，确保测量的PPG信号值的稳定性，如图4示出的手表佩戴正确时测得的PPG信号值稳定，没有发生突变。
此外，当手表佩戴过紧时，同样会影响手表测量心率的准确性。如图5示出的手表佩戴松紧与心率准确率关系示意图。从图中可以看出，随着佩戴松紧由过松、松到紧，所测量的心率准确率越来越高，当佩戴松紧为紧(图2中右图所示的正确佩戴方式)时，心率 准确率最高，但若佩戴手表过紧时，心率准确率反而降到最低。图中准确率具体为测量值与标准值相差小于5bpm(Beat Per Minute)的概率。
因此，本申请提出了一种可穿戴设备的检测方法，可以检测可穿戴设备的佩戴松紧，保证心率测量的准确性。
接下来请参见图6。图6为本申请实施例提供的一种可穿戴设备的检测方法流程示意图，如图6所示，一种可穿戴设备的检测方法至少可以包括以下几个步骤：
S101：若可穿戴设备的佩戴状态为已佩戴，获取基于上述可穿戴设备与佩戴者的当前接触状态产生的信号值。
具体地，可穿戴设备的佩戴状态包括已佩戴和未佩戴。
具体地，基于上述可穿戴设备与佩戴者的当前接触状态产生的信号值即为基于可穿戴设备的佩戴松紧程度产生的信号值。其中，信号值可以是PPG信号值或者电容值等，还可以是其他能够反映可穿戴设备的佩戴松紧程度的信号值。
在一种可能的实现方式中，在判断出可穿戴设备的佩戴状态为已佩戴，获取基于上述可穿戴设备与佩戴者的当前接触状态产生的信号值之前，该方法还包括接收佩戴者输入的测量生理参数的指令。
其中，测量生理参数的指令可以是佩戴者语音输入的指令，或者是佩戴者基于可穿戴设备的操作界面中相应的控件输入测量生理参数的指令，或者是佩戴者按下可穿戴设备的实体按键，或者是佩戴者输入特定的手势作为测量生理参数的指令，或者是佩戴者通过与可穿戴设备连接的手机等终端向可穿戴设备发出测量生理参数的指令，等等。可以理解的是，输入测量生理参数的指令可以有多种实现方式，在此不做限制。
S102：若根据上述信号值及信号门限值判断出上述当前接触状态不满足测量条件，发出第一提示消息。
具体地，信号门限值包括基于可穿戴设备与佩戴者的第一接触状态产生的信号门限值。其中，第一接触状态即为可穿戴设备的佩戴松紧合适，亦即图5中的佩戴松紧为紧时的状态。
具体地，测量条件由上述信号值决定，不同的信号值对应的测量条件不同。具体的信号值与测量条件的对应关系可详见后续实施例中的描述。
具体地，第一提示消息用于提示佩戴者调整佩戴上述可穿戴设备。其中，第一提示消息可以是可穿戴设备通过操作界面显示对话框或者动画提示；第一提示消息还可以是可穿戴设备语音提示；第一提示消息还可以是通过操作界面显示与振动结合的方式提示；第一提示消息还可以是语音与振动结合的方式提示。如图7示例性示出了通过操作界面显示与振动结合的方式提示的第一提示消息。可以知道的是，第一提示消息的提示方式还可以有其他的实现方式，不限于前述的实现方式，在此不做限制。
此外，若根据上述信号值及信号门限值判断出上述当前接触状态满足测量条件时，开始测量生理参数。
实施本申请实施例可以在检测到可穿戴设备的佩戴状态为已佩戴后，获取基于可穿戴设备与佩戴者的当前接触状态产生的信号值；若根据该信号值与信号门限值判断当前接触状态不满足测量条件，则发出第一提示消息，提示佩戴者调整佩戴可穿戴设备，智能检测 可穿戴设备的佩戴松紧，进而保证心率测量的准确性。
接下来请参见图8。图8为本申请另一实施例提供的可穿戴设备的检测方法流程示意图，如图8所示，可穿戴设备的检测方法至少可以包括以下几个步骤：
S201：获取信号门限值。
具体地，信号门限值包括基于可穿戴设备与佩戴者的第一接触状态产生的信号门限值，信号门限值包括最大门限值及最小门限值。其中，第一接触状态即为可穿戴设备的佩戴松紧合适，亦即图5中的佩戴松紧为紧时的状态。可以知道的是，信号门限值由基于上述可穿戴设备与佩戴者的第一接触状态产生的信号值决定。其中，上述信号值可以是PPG信号值或者电容值等，还可以是其他能够反映可穿戴设备的佩戴松紧程度的信号值。
可选地，上述信号值可以为PPG信号值。可以采用光电传感器测量PPG信号，获得PPG信号值。具体地，光电传感器可设置于智能手表的表盘内侧，如图9中的10区域所示。
此时，获取信号门限值的方法如图10所示，至少可以包括以下几个步骤：

其中，上述N为正整数。N例如可以是5、10、13、15、20等等。N值越大，最终获得的信号门限值越准确。
具体地，第二提示消息用于在检测到上述可穿戴设备的佩戴状态为已佩戴后，提示佩戴者输入指定动作。其中，第二提示消息的提示方式与第一消息的提示方式类似。具体地，第二提示消息可以是可穿戴设备通过操作界面显示对话框或者动画提示；第二提示消息还可以是可穿戴设备语音提示；第二提示消息还可以是通过操作界面显示与振动结合的方式提示；第二提示消息还可以是语音与振动结合的方式提示。如图11示例性示出了通过操作界面显示的第二提示消息。可以知道的是，第二提示消息的提示方式还可以有其他的实现方式，不限于前述的实现方式，在此不做限制。
具体地，指定动作可以是手臂绕“8”字，或者摇晃手臂(上下摇晃手臂、左右摇晃手臂)、举起手臂、手背按某一角度挥扫、曲线挥扫、翻转手腕、顺时针旋转手臂、逆时针旋转手臂等。如图12所示的场景示意图，佩戴者在接收到上述第二提示消息之后，按照提示输入指定动作。
具体地，预设时长可以是5s、10s、20s、30s等。在预设时长内基于上述可穿戴设备与佩戴者的第一接触状态，佩戴者根据第二提示消息输入指定动作，产生的信号值为连续信号。

在另外一种可能的实现方式中，最大门限值可以是上述N各最大值中的最大值，最小门限值可以是上述N个最小值中的最小值。
可选地，上述信号值可以为电容值。可以采用电容传感器测量电容，获得电容值。可穿戴设备佩戴的松紧程度不同，电容传感器采集的电容值也不相同，如图13所示。从图13可以看出，电容传感器采集到的电容值越大，表明手表的感应器越贴近皮肤；电容传感器采集到的电容值越小，表明手表的感应器离皮肤越远，即手表佩戴松。具体地，电容传感器可以设置在如图9所示的包括表盘内侧10、表带内侧20的多个地方。
此时，获取信号门限值的方法还可以如图14所示，至少可以包括以下几个步骤：

可选地，检测上述可穿戴设备的佩戴状态的检测方式可以是通过结合上述两种方式来判断。即结合肌电信号的电平值与表带的搭扣状态来判断。若检测到上述肌电信号为高电平且表带的搭扣状态为已扣上，则检测出上述可穿戴设备的佩戴状态为已佩戴；否则，则检测出上述可穿戴设备的佩戴状态为未佩戴。
具体地，可以是可穿戴设备根据上述检测方式检测的结果判断其自身的佩戴状态，还可以是可穿戴设备将根据上述检测方式检测的结果通过网络上传至服务器或者其他设备，使上述服务器或者其他设备根据该检测结果判断上述可穿戴设备的佩戴状态。
S204：若可穿戴设备的佩戴状态为已佩戴，获取基于上述可穿戴设备与佩戴者的当前接触状态产生的信号值。

具体地，方差越小，表示当前测得的PPG信号值越稳定。方差阈值例如可以是0.02、0.05、0.1等。
S504：若上述第一方差与上述第二方差中至少有一项不小于上述方差阈值，则判断出上述当前接触状态不满足测量条件，发出第一提示消息。
具体地，若上述第一方差与上述第二方差中至少有一项不小上述方差阈值，即最大值或/和最小值发生了突变，则说明基于上述可穿戴设备与佩戴者的当前接触状态产生的PPG信号值不稳定，表明上述可穿戴设备的佩戴松紧不合适，发出第一提示消息提示佩戴者重新调整佩戴上述可穿戴设备。
