 本发明的实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
图1为一个实施例中基于血氧饱和度的评估方法的应用环境图。参照图1，该基于血氧饱和度的评估方法应用于基于血氧饱和度的评估***。该基于血氧饱和度的评估***包括智能可穿戴设备110和服务器120。智能可穿戴设备110和服务器120通过网络连接，智能可穿戴设110可以是智能手表、也可以是智能头盔、还可以是智能戒指等。服务器120可以用独立的服务器或者多个服务器组成的服务器集群来实现。智能可穿戴设备110用于获取待评估用户对应的海拔高度和血氧饱和度，将获取到的海拔高度和血氧饱和度上传到服务器120，服务器120用于获取待评估用户对应的海拔高度和血氧饱和度，根据海拔高度和血氧饱和度确定待评估用户对应的评估结果。
在另一个实施例中，基于血氧饱和度的评估方法可直接应用于智能可穿戴设备110，智能可穿戴设备110用于获取待评估用户对应的海拔高度和血氧饱和度，根据海拔高度和血氧饱和度确定待评估用户对应的评估结果。
如图2所示，提出了一种基于血氧饱和度的评估方法，该方法既可以用于智能可穿戴设备，也可以应用于与智能可穿戴设备连接的计算机设备，还可以用于服务器，本实施例以应用于智能可穿戴设备举例说明。该基于血氧饱和度的评估方法具体包括以下步骤：
步骤202，获取待评估用户对应的海拔高度和血氧饱和度。
其中，血氧饱和度（SpO2）是反应机体供氧水平的重要指标。通过获取待评估用户的海拔高度和血氧饱和度来对用户的高原适应性进行预测。海拔高度可以通过智能可穿戴设备中的海拔高度测量仪测量得到，也可以通过GPS定位测量得到，还可以是用户输入的海拔高度。血氧饱和度可以通过智能可穿戴设备中的血氧传感器检测得到。血氧饱和度可以实时进行检测，也可以每隔预设时间间隔检测一次。获取到的血氧饱和度可以是当前时刻对应的血氧饱和度，也可以是前面时刻的血氧饱和度。
步骤204，根据海拔高度和血氧饱和度确定待评估用户对应的评估结果。
其中，评估结果可以是评估得到的适应性等级（比如，将适应性分为三个等级，确定当前待评估用户对应的适应性等级），还可以是得到的评估建议（比如，是否继续爬升的建议，以及能够继续爬升高度的建议），也可以是给出的适应性分数（比如，可以按照十分制或百分值评估出待评估用户对应的分数），当然也可以是其他可以用于表征适应性的评估结果。
在一个实施例中，获取待评估用户对应的当前海拔高度和当前血氧饱和度，获取待评估用户对应的标准血氧饱和度（即在平原高度时对应的血氧饱和度），根据当前海拔高度、当前血氧饱和度和标准血氧饱和度确定待评估用户对应的评估结果。
在另一个实施例中，通过获取待评估用户在某一段时间内的血氧饱和度，计算出血氧饱和度的变化率，根据血氧饱和度的变化率和当前血氧饱和度确定待评估用户对应的评估结果。
在一个实施例中，分别获取第一海拔高度下的第一血氧饱和度和第二海拔高度下的第二血氧饱和度，根据第一血氧饱和度和第二血氧饱和度计算血氧饱和度的变化率，然后血氧饱和度的变化率和当前血氧和度确定待评估用户对应的评估结果。
上述基于血氧饱和度的评估方法，通过获取待评估用户对应的海拔高度和血氧饱和度，然后根据海拔高度和血氧饱和度确定待评估用户对应的评估结果。根据海拔高度和血氧饱和度可以及时对待评估用户的适应性进行评估，从而能够提前预防高原反应和高原病的发生。
在一个实施例中，所述获取待评估用户对应的海拔高度和血氧饱和度，包括：获取待评估用户对应的预测海拔高度；根据所述海拔高度和所述血氧饱和度确定所述待评估用户对应的评估结果，包括：根据所述待评估用户对应的血氧饱和度计算血氧饱和度变化率；根据所述预测海拔高度和所述血氧饱和度变化率确定所述待评估用户对应的评估结果。
其中，预测海拔高度是指待评估用户要预测的海拔高度，即预测待评估用户在该预测海拔高度下的适应性评估结果。在一个实施例中，获取待评估用户在不同海拔高度对应的血氧饱和度，然后根据不同海拔高度对应的血氧饱和度计算血氧饱和度变化率，根据血氧饱和度变化率和预测海拔高度计算在预测海拔高度下对应的预测血氧饱和度，根据预测血氧饱和度确定待评估用户在该预测海拔高度对应的评估结果。待评估用户可以通过输入自己想要爬升到的海拔高度（即预测海拔高度），进而根据预测海拔高度来计算待评估用户在该预测海拔高度下的适应性评估结果，从而可以指导后续的运动。在另一个实施例中，直接从智能可穿戴设备中获取统计得到的血氧饱和度变化率以及某一海拔高度下的血氧饱和度，然后根据血氧饱和度变换率、某一海拔高度下的血氧饱和度以及预测海拔高度来计算待评估用户在该预测海拔高度下的适应性评估结果。
如图3所示，提出了一种基于血氧饱和度的评估方法，该方法包括：
步骤302，获取待评估用户对应的当前海拔高度和当前血氧饱和度。
其中，血氧饱和度是反应机体供氧水平的重要指标。可以通过检测当前血氧饱和度来评估高原适应性。当前海拔高度是指待评估用户当前所在的海拔高度。当前血氧饱和度是指检测得到的待评估用户当前的血氧饱和度。通过智能可穿戴设备可实时检测使用者（即待评估用户）对应的当前海拔高度和当前血氧饱和度。在智能可穿戴设备上安装有血氧传感器和海拔高度测量仪，通过血氧传感器检测血氧饱和度，通过海拔高度测量仪检测当前所在的海拔高度。
步骤304，获取待评估用户在第一海拔高度对应的第一血氧饱和度，第一海拔高度小于当前海拔高度。
其中，第一海拔高度是指小于当前海拔高度的海拔高度。在一个实施例中，第一海拔高度可以采用血氧饱和度处于平稳状态的海拔高度，即平原海拔高度。第一血氧饱和度是指在第一海拔高度对应的血氧饱和度。经过大量研究表明，当在海拔高度2500米以下时，血氧饱和度波动较小。所以可以将第一海拔高度设置为小于2500米的任一海拔高度，通过智能可穿戴设备获取在第一海拔高度时的第一血氧饱和度。
步骤306，根据当前血氧饱和度和第一血氧饱和度确定待评估用户在当前海拔高度对应的评估结果。
其中，通过将当前血氧饱和度与第一血氧饱和度进行比较来确定相应的高原适应性评估结果。在一个实施例中，当第一血氧饱和度与当前血氧饱和度的差值大于预设阈值时，则说明待评估用户的高原适应性较差，不建议再继续爬升。当第一血氧饱和度与当前血氧饱和度的差值不大于预设阈值时，则说明待评估用户的高原适应性较好，可以适当地爬升。
在另一个实施例中，可以设置第一预设阈值，第二预设阈值，第一预设阈值大于第二预设阈值。当第一血氧饱和度与当前血氧饱和度的差值大于第一预设阈值时，则相应地将适应性设置为A等级；当第一血氧饱和度与当前血氧饱和度的差值不大于第一预设阈值，且大于第二预设阈值时，则相应地将适应性设置为B等级；当第一血氧饱和度与当前血氧饱和度的差值不大于第二预设阈值时，则相应地将适应性设置为C等级。其中，A等级代表适应性很差，建议下高原。B等级代表适应性一般，建议休息。C等级代表适应性较强，可以继续爬升。根据当前血氧饱和度和第一血氧饱和度及时评估高原适应性，便于提前预防高原反应的发生。
在一个实施例中，高原适应性评估结果中包含有适应等级以及相应的建议。比如，如果评估结果为A等级，在评估结果中同时包含相应的建议，比如，建议下高原。通过将高原适应性评估结果显示在智能可穿戴设备上，可以及时提醒待评估用户，预防高原反应的发生。
上述基于血氧饱和度的评估方法，通过检测待评估用户对应的当前海拔高度和当前血氧饱和度，获取待评估用户在第一海拔高度对应的第一血氧饱和度，根据当前血氧饱和度和第一血氧饱和度确定待评估用户在当前海拔高度的适应性结果。通过当前血氧饱和度和第一血氧饱和度可以及时对待评估用户的高原适应性进行评估，便于给出相应的建议，能够提前预防高原反应和高原病的发生并指导运动。
如图4所示，在一个实施例中，提出了一种基于血氧饱和度的评估方法，该方法包括：
步骤402，获取待评估用户对应的当前海拔高度和当前血氧饱和度。
步骤404，获取待评估用户在第一海拔高度对应的第一血氧饱和度，第一海拔高度小于当前海拔高度。
步骤406，根据当前海拔高度计算得到对应的当前血氧饱和度预警值。
其中，血氧饱和度预警值是指在容易出现高原反应的血氧饱和度值。不同的海拔高度对应不同的血氧饱和度预警值，获取到当前海拔高度后计算得到当前海拔高度对应的当前血氧饱和度预警值。
步骤408，根据当前血氧饱和度、第一血氧饱和度和当前血氧饱和度预警值确定待评估用户对应的评估结果。
其中，通过综合考虑当前血氧饱和度、第一血氧饱和度和当前血氧饱和度预警值来计算待评估用户的高原适应性。在一个实施例中，当第一血氧饱和度与当前血氧饱和度之差大于预设阈值（比如，30%），则将相应的高原适应性评估结果设置为I级。当当前血氧饱和度大于第一血氧饱和度与预设阈值之差，且小于当前血氧饱和度预警值时，则将相应的高原适应性评估结果设置为II级。当当前血氧饱和度不小于当前血氧饱和度预警值时，则相应地将高原适应性评估结果设置为III级。其中，III级的适应性>II级的适应性大>I级的适应性。
在一个实施例中，根据当前海拔高度计算得到对应的当前血氧饱和度预警值，包括：获取海拔高度和血氧饱和度预警值之间的关联关系，关联关系是通过统计不同海拔高度下发生高原反应和非高原反应对应的血氧饱和度得到的；根据关联关系计算得到当前海拔高度对应的当前血氧饱和度预警值。
其中，预先设置海拔高度与血氧饱和度预警值之间的关联关系。关联关系是通过统计分析大量的在不同海拔高度下发生高原和非高原反应对应的血氧饱和度的数据得到的。在一个实施例中，分析得到的海拔高度与血氧饱和度预警值之间满足线性关系。可以采用以下公式表示：f(x)=k1+k2*x+k3*x^2。其中，f(x)表示血氧饱和度预警值，x为海拔高度，k1、k2和k3为常数。在已知当前海拔高度x时，便可计算得到当前血氧饱和度预警值。在一个实施例中，k1的取值范围在（90.07，93.9）之间，k2的取值范围在（-0.0005465,0.002189）之间，k3的取值范围在（-9.549*10 -7，-5.113*10 -7）之间。
在一个实施例中，根据当前血氧饱和度、第一血氧饱和度和当前血氧饱和度预警值确定待评估用户的适应性结果，包括：当当前血氧饱和度与第一血氧饱和度的差值大于预设阈值时，则确定待评估用户对应的评估结果为第一适应等级；当当前血氧饱和度小于血氧饱和度预警值，且大于第一血氧饱和度与预设阈值的差值时，则确定待评估用户对应的评估结果为第二适应等级。
其中，预先设置预设阈值，预设阈值可根据经验统计得到，根据文献“动脉血氧饱和度降低幅度可预示高原肺水肿易感性”的结论得出在高原上血氧饱和度相对于平原上降低30%可作为预测高原肺水肿高危人群风险的指标，具有普遍适用价值，所以预设阈值可以设置为30%。当当前血氧饱和度相对于第一血氧饱和度下降了30%以上时，则确定待评估用户对应的评估结果为第一适应等级。当当前血氧饱和度大于第一血氧饱和度减去30%，且小于血氧饱和度预警值时，则确定对应的评估结果为第二适应等级。在一个实施例中，第一适应等级表示非常不适应，建议下高原。第二适应等级表示不适应，建议休息。
如图5所示，在一个实施例中，上述基于血氧饱和度的评估方法还包括：
步骤502，获取待评估用户对应的当前海拔高度和当前血氧饱和度。
步骤504，获取待评估用户在第一海拔高度对应的第一血氧饱和度，第一海拔高度小于当前海拔高度。
步骤506，根据当前海拔高度计算得到对应的当前血氧饱和度预警值。
步骤508，获取待评估用户对应的当前运动强度。
其中，当前运动强度是指当前的运动状态。可以采用检测得到的心率来表示运动强度，心率越快，表示运动强度越大。
步骤510，根据当前运动强度和当前海拔高度计算得到对应的当前血氧饱和度标准值。
其中，血氧饱和度标准值是指在海拔高度和运动情况下统计得到的血氧饱和度的正常值。海拔高度和运动强度是影响血氧饱和度的两个因素。同样的海拔高度下，运动强度越大，相应的血氧饱和度下降越多；同样的运动强度，不同的海拔高度，海拔越高，血氧饱和度下降越多。获取当前运动强度和当前海拔高度，就可以计算得到当前血氧饱和度标准值。
步骤512，根据当前血氧饱和度、第一血氧饱和度、当前血氧饱和度预警值、当前血氧饱和度标准值计算得到待评估用户对应的评估结果。
其中，通过比较当前血氧饱和度、第一血氧饱和度、当前血氧饱和度预警值以及当前血氧饱和度标准值得到待评估用户的高原适应性。在一个实施例中，当当前血氧饱和度小于第一血氧饱和度与预设阈值之间的差值时，设置为第I等级。当当前血氧饱和度不小于第一血氧饱和与预设阈值之间的差值，且小于当前血氧饱和度预警值时，则设置为第II等级，当当前血氧饱和度大于当前血氧饱和度预警值小于当前血氧饱和度标准值时，设置为第III等级；当当前血氧饱和度大于当前血氧饱和度标准值时，设置为第IV等级。其中，第IV等级的适应性>第III等级的适应性>第II等级的适应性>第I等级的适应性。
在一个实施例中，根据当前运动强度和当前海拔高度计算得到对应的当前血氧饱和度标准值，包括：获取海拔高度、运动强度和血氧饱和度标准值之间的因果关系，因果关系是通过采集不同海拔高度不同运动强度下血氧饱和度分析得到的；根据因果关系计算得到与当前运动强度和当前海拔高度对应的当前血氧饱和度标准值。
其中，预先计算得到海拔高度、运动强度和血氧饱和度标准值三者之间的关联关系（即因果关系）。因果关系是通过采集大量的不同海拔高度不同运动强度下对应的血氧饱和度数据，然后进行统计分析得到的。在一个实施例中，血氧饱和度标准值与海拔高度、运动强度之间成线性关系。海拔高度、运动强度分别与血氧饱和度标准值成反相关。即海拔高度越高，血氧饱和度标准值越小，运动强度越大，血氧饱和度越小。在已知当前运动强度和当前海拔高度的情况下，就可以根据该线性关系计算得到当前血氧饱和度标准值。在一个实施例中，可以采用以下公式表示三者之间的关系：g(x)=p1+p2*x+p3*y+p4*x^2+p5*x*y。其中，x表示海拔高度，y表示运动强度，g(x)表示血氧饱和度标准值。p1、p2、p3、p4和p5为相应的已知系数。其中，p1的取值范围在（90.89，105.7）之间，p2的取值范围在（-1.303，6.345）之间，p3的取值范围在（-2.192，1.412）之间，p4的取值范围在（-1.928，-0.7965），p5的取值范围在（-0.6572，0.2704）之间。
在一个实施例中，根据当前血氧饱和度、第一血氧饱和度、当前血氧饱和度预警值、当前血氧饱和度标准值计算得到待评估用户的适应性结果，包括：当当前血氧饱和度大于当前血氧饱和度预警值，且当前血氧饱和度标准值小于当前血氧饱和度预警值时，确定待评估用户对应的评估结果为第三适应等级；当当前血氧饱和度大于当前血氧饱和度预警值，且当前血氧饱和度标准值不小于当前血氧饱和度预警值时，确定待评估用户对应的评估结果为第四适应等级。
其中，判断当前血氧饱和度与当前血氧饱和度预警值、当前血氧饱和度标准值之间的大小关系，当当前血氧饱和度大于当前血氧饱和度预警值，且当前血氧饱和度标准值小于当前血氧饱和度预警值，则判定高原适应性等级为第三适应等级。当当前血氧饱和度大于当前血氧饱和度预警值，且当前血氧饱和度标准值不小于当前血氧饱和度预警值时，则判定高原适应性等级为第四适应等级。第三适应等级表示适应一般，建议休息为主，可以进行适当的适应性活动，但不要剧烈运动。第四适应等级表示适应良好，建议可以以适当的运动强度继续爬升。
在一个实施例中，上述基于血氧饱和度的评估方法还包括：获取预设的血氧饱和度安全临界值和预设的运动强度；根据当前血氧饱和度、血氧饱和度安全临界值和预设的运动强度计算得到待评估用户对应的可爬升高度。
其中，血氧饱和度安全临界值是指不会发生高原反应的血氧饱和度的最小安全值。血氧饱和度安全临界值可以预先设置，也可以将血氧饱和度预警值作为血氧饱和度安全临界值。预设的运动强度可以是一个，也可以是多个。不同的运动强度对应的可爬升高度不同。在一个实施例中，也可以直接将当前运动强度作为预设的运动强度。根据当前血氧饱和度、血氧饱和度安全临界值以及预设的运动强度可以预计算出待评估用户以预设的运动强度还可以爬升的距离。然后给出待评估用户相应的爬升建议。在一个实施例中，当高原适应性评估结果为良好时，才会给出具体的建议爬升距离。可以采用以下公式计算得到可爬升距离，h(x)=ax+bx^2+c*xy，其中，h(x)代表血氧饱和度下降的数值，x代表可爬升距离，y代表预设的运动强度，a、b、c代表相应的常系数。根据当前血氧饱和度和血氧饱和度安全临界值计算得到血氧饱和度下降的数值h(x)，已知h(x)和y的情况下，就可以计算得到可爬升距离x。
如图6所示，为一个实施例中，应用基于血氧饱和度的评估方法的示意图。如图6所示，智能可穿戴设备（比如，智能可穿戴手表）中包括：高度计模块、光电心率模块和光电血氧模块，高度计模块用于测量得到海拔高度，光电心率模块用于测量得到心率，即运动强度。光电血氧模块用于测量得到血氧饱和度。首先，高度计模块在平原时（2500米以下）测量得到平原海拔高度G1和同时光电血氧模块测量得到的血氧饱和度S1，当到达高原时（2500米以上），实时通过高原计模块测量得到当前海拔高度G2，通过光电心率模块测量得到当前运动强度y，通过光电血氧模块测量得到当前血氧饱和度S2，通过当前运动强度和当前海拔高度计算得到当前血氧饱和度标准值Y，通过当前海拔高度计算得到当前血氧饱和度预警值K。通过比较S1、S2、K和Y之间的数值关系计算得到待评估用户对应的适应等级，然后根据适应等级给出相应的建议，并将建议显示在智能可穿戴设备上。
在一个实施例中，当S1小于S2-30%时，表示高原适应性为A等级，A等级的血氧饱和度区间范围在（64%-70%）之间；当S1大于S2-30%，且小于K值时，表示高原适应性为B等级，B等级的血氧饱和度区间范围在（64%-85%）；当S1大于K，且K大于Y值时，表示高原适应性为C等级，C级的血氧饱和度区间范围在（70%-90%）之间；当S1大于K，且K不大于Y时，则表示高原适应性为D级，D级的血氧饱和度区间范围在（75%-94%）之间。
在一个实施例中，智能可穿戴设备中包括了血氧传感器以及压力传感器，血氧传感器和压力传感器是设置在例如智能手表或者头戴式可穿戴设备等设备上的；其中，血氧传感器可用于检测佩戴者的血氧饱和度。压力传感器可用于检测佩戴者在佩戴上述可穿戴设备的过程中的佩戴压力，例如，检测佩戴者在佩戴智能手表的过程中表带对于手腕的压力值的大小，再例如，检测佩戴者在佩戴头戴式可穿戴设备的过程中该头戴式可穿戴设备对于头部的压力值的大小。
在一个实施例中，血氧传感器还包括红外光发射单元、红光发射单元、光线检测单元；通过红外光发射单元向被测对象发射红外光，通过红光发射单元向被测对象发射红光；通过光线检测单元接收被测对象反射的与红外光、以及红光对应的光信号，并将光信号通过光电接收器转换成电信号；计算光线检测单元接收的红光信号的交流幅度与直流幅度的第一比值，计算光线检测单元接收的红外光信号的交流幅度与直流幅度的第二比值，通过计算第一比值与第二比值的比值确定初始血氧饱和度值。通过所述压力传感器检测智能可穿戴设备在佩戴过程中的佩戴压力值作为目标压力值；根据预设的压力校准数据模型以及目标压力值对初始血氧饱和度值进行滤波处理，得到与初始血氧饱和度值对应的校正血氧饱和度值。
在一个具体的实施例中，如图7和8所示，给出了一个具体的实施例中压力传感器200的安装实例，压力传感器200与壳体300固定在一起，通过壳体300的形变来检测压力，并且壳体300上有孔径可供光通过。具体的，如图5所示，压力传感器200为圆形，血氧传感器100设置在一安装板400上，然后将安装板400、压力传感器200以及壳体300固定在一起；如图6所示，压力传感器为矩形200，压力传感器与血氧传感器100、壳体300固定在一起。
如图9所示，提出了一种基于血氧饱和度的评估装置，该装置包括：
获取模块902，用于获取待评估用户对应的海拔高度和血氧饱和度；
确定模块904，用于根据所述海拔高度和所述血氧饱和度确定所述待评估用户对应的评估结果。
