血氧指血液中的氧气，人体正常含氧量为90％左右。一定范围内血液中含氧量越高，人的新陈代谢就越好。血氧检测时通常会用到光电容积图(Photo-Plethysmography，PPG)。PPG检测血氧需要在人体手指上获取较平滑的数据。检测时不同人的皮肤状况、被检测人所处的环境光线等因素都会影响检测的结果。为了获得良好的检测结果，对用户进行检测时需要设置较大的检测功率(即较大的采样频率)。但由于肤质以及检测环境的差别，对一些用户进行检测时，在小功率下也可以获得良好的检测结果。若此时再用对检测仪设置的统一功率(默认设置的检测功率一般较大)对这样的用户进行检测，无疑会浪费部分功耗。Blood oxygen refers to oxygen in the blood, and the normal oxygen content of the human body is about 90%. The higher the oxygen content in the blood within a certain range, the better the human metabolism. Photo-Plethysmography (PPG) is usually used for blood oxygenation. PPG detection of blood oxygen requires smoother data on human fingers. Factors such as the skin condition of different people during the test and the ambient light of the person being tested may affect the results of the test. In order to obtain good detection results, it is necessary to set a large detection power (ie, a large sampling frequency) when detecting the user. However, due to differences in skin quality and detection environment, good detection results can be obtained at low power when testing some users. If the unified power set to the detector is used at this time (the default detection power is generally large) to detect such a user, some power consumption will undoubtedly be wasted.

为了说明本申请所述的技术方案，下面通过具体实施例来进行说明。In order to explain the technical solutions described in the present application, the following description will be made by way of specific embodiments.
实施例1Example 1
图1示出了本申请实施例中提供的一种功率控制方法的流程示意图，详述如下：FIG. 1 is a schematic flowchart diagram of a power control method provided in an embodiment of the present application, which is described in detail as follows:
步骤S11，获取检测设备对目标项目所设定的当前的检测功率；Step S11, acquiring current detection power set by the detecting device for the target item;
本申请提供的实施例中，检测设备对人体进行PPG血氧检测时，首先获取检测设备对目标项目所设定的当前的检测功率。其中，所述检测功率小于额定功率。可选地，所述目标项目可以包括多个检测指标，如血氧、血压等。In the embodiment provided by the present application, when the detecting device performs PPG oximetry on the human body, firstly, the current detection power set by the detecting device for the target item is acquired. Wherein the detection power is less than the rated power. Optionally, the target item may include a plurality of detection indicators, such as blood oxygen, blood pressure, and the like.
可选地，在获取检测设备对目标项目所设定的当前的检测功率时，检测用户当前所处的睡眠期(例如，用户处于清醒期或深睡眠期等)，确定用户所处的睡眠期后，获取检测设备对该睡眠期所设定的当前的检测功率。若检测设备未设定当前的检测功率，可根据检查设备的运行环境以及被检测用户的实际情况，对当前的检测功率进行预设定。Optionally, when acquiring the current detection power set by the detection device for the target item, detecting a sleep period currently in which the user is located (eg, the user is in an awake period or a deep sleep period, etc.), determining the sleep period of the user. After that, the current detection power set by the detecting device for the sleep period is acquired. If the detection device does not set the current detection power, the current detection power may be preset according to the operating environment of the inspection device and the actual situation of the detected user.
步骤S12，根据所述当前的检测功率采集所述检测设备检测所述目标项目时的采样信号；Step S12, collecting, according to the current detection power, a sampling signal when the detecting device detects the target item;
该步骤中检测设备以所获取的当前的检测功率开始执行检测任务，获取检测目标项目时的采样信号，例如获取检测设备检测用户血氧时的采样信号。可选地，在获取所述采样信号时，每次可获取预设时长的采样信号，例如每次采集5秒或10秒或其他时长的采样信号。其中，所述采样信号包括通过PPG的光电传感器接收的反射光强度信号等相关数据。PPG光照照射时间间隔即为脉宽。脉宽长度对功率有影响，脉宽长度越长，功耗越大，适当调节脉宽可以保证信号的质量。但光照时间越长就意味着功率越大。In this step, the detecting device starts to perform the detecting task with the acquired current detecting power, and acquires a sampling signal when detecting the target item, for example, acquiring a sampling signal when the detecting device detects the user's blood oxygen. Optionally, when acquiring the sampling signal, a sampling signal of a preset duration may be acquired each time, for example, sampling signals of 5 seconds or 10 seconds or other durations are collected each time. The sampling signal includes related data such as a reflected light intensity signal received by a photoelectric sensor of the PPG. The PPG illumination interval is the pulse width. The length of the pulse width has an influence on the power. The longer the pulse width length, the larger the power consumption, and the proper adjustment of the pulse width can ensure the quality of the signal. But the longer the illumination time, the greater the power.
步骤S13，根据预设规则对所述采样信号进行质量评估，得到所述当前的检测功率下采样信号的评估值；Step S13, performing quality assessment on the sampling signal according to a preset rule, to obtain an evaluation value of the current detection power downsampling signal;
本申请提供的实施例中，根据预设规则对获取的采样信号进行质量评估，以确定当前的检测功率是否能满足检测要求。In the embodiment provided by the present application, the obtained sampling signal is subjected to quality evaluation according to a preset rule to determine whether the current detection power can meet the detection requirement.
具体地，在对采样信号的质量进行评估时，可获取采样信号相关参数的特征值，例如对于PPG的光电传感器接收的反射光强度信号，其特征值可以是波峰峰值、波形偏移度以及光源相关系数等。对上述特征值进行评估，判断其是否达到用户设定的相应的最小检测值，若达到，则确定采样信号该项的特征值合格，进而统计合格特征值与不合格特征值，计算出采样信号的评估值。Specifically, when the quality of the sampled signal is evaluated, the characteristic value of the parameter related to the sampled signal may be obtained, for example, the reflected light intensity signal received by the photoelectric sensor of the PPG, and the characteristic value may be a peak value, a waveform offset, and a light source. Correlation coefficient, etc. The feature value is evaluated to determine whether it reaches the corresponding minimum detection value set by the user. If it is reached, it is determined that the characteristic value of the sampling signal item is qualified, and then the qualified characteristic value and the unqualified characteristic value are counted, and the sampling signal is calculated.

步骤S14，获取所述目标项目的采样信号对应的标准评估值；Step S14, acquiring a standard evaluation value corresponding to the sampling signal of the target item;

可选地，在本申请提供的另一实施例中，在所述获取所述目标项目的采样信号对应的标准评估值之前，包括：Optionally, in another embodiment provided by the present application, before the acquiring the standard evaluation value corresponding to the sampling signal of the target item, the method includes:

具体地，在设定所述标准评估值之前，对预设数量的用户进行检测。统计检测每个用户目标项目的过程中，所获取的采样信号满足检测要求时，每项特征值的大小。根据统计结果确定采样信号所需的合格标准。Specifically, a preset number of users are detected before the standard evaluation value is set. The size of each feature value when the sampled signal obtained meets the detection requirement during the process of statistically detecting each user's target item. The eligibility criteria required to sample the signal are determined based on statistical results.
步骤S15，根据所述评估值与所述标准评估值的关系调节所述当前的检测功率。Step S15, adjusting the current detection power according to the relationship between the evaluation value and the standard evaluation value.
该步骤中根据当前的采样信号的评估值与标准评估值的关系对当前的检测功率进行调节。具体地，当所述评估值大于所述标准评估值时，降低所述当前的检测功率。进一步地，分析调整检测功率后，所获取的采集信号的评估值与标准评估值的关系，使调整后检测功率下所获取的采样信号的评估值与标准评估值之差在第一预设值和第二预设值之间。其中，所述第一预设值可以为0，第二预设值为大于0，且较小的数(如评估值以百分数表示时，第二预设值可以为5％，或更小的数)，具体数值可由用户根据检查设备的状况以及被检测用户自身情况进行设定。若所述评估值小于标准评估值，则增大所述当前的检测功率至合适的功率值。In this step, the current detection power is adjusted according to the relationship between the evaluation value of the current sampling signal and the standard evaluation value. Specifically, when the evaluation value is greater than the standard evaluation value, the current detection power is decreased. Further, after analyzing and adjusting the detection power, the relationship between the obtained evaluation value of the acquired signal and the standard evaluation value is such that the difference between the evaluation value of the sampled signal obtained under the adjusted detection power and the standard evaluation value is at the first preset value. Between the second preset value and the second preset value. The first preset value may be 0, the second preset value is greater than 0, and the smaller number (if the evaluation value is expressed as a percentage, the second preset value may be 5%, or smaller) The specific value can be set by the user according to the condition of the inspection device and the detected user's own situation. If the evaluation value is less than the standard evaluation value, the current detection power is increased to a suitable power value.
可选地，若当前检测的所述评估值与标准评估值之间的差值在第一预设值和第二预设值之间，则不进行功率调节；并以当前的检测功率对用户进行检测一段时间(如1分钟、5分钟或其他时长)后，再次将评估值与标准评估值进行对比以确定是否进行功率调节。Optionally, if the difference between the currently detected evaluation value and the standard evaluation value is between the first preset value and the second preset value, no power adjustment is performed; and the current detection power is used for the user. After a period of detection (eg, 1 minute, 5 minutes, or other length of time), the evaluation value is again compared to the standard evaluation value to determine whether power adjustment is made.
本申请提供的实施例中检测设备在对人体血氧或其他目标项目进行检测时，首先获取检测设备对所要检测的目标项目所设定的当前的检测功率；获取所述当前的检测功率下的采样信号，根据预设规则对所述采样信号进行质量评估，以获得采样信号的评估值，然后获取该目标项目采样信号对应的标准评估值，根据二者的差异调节当前的检测功率至合适的功率。这一过程中检测设备根据在当前的检测功率下所获取的采样信号的评估值与标准评估值之间的关系，对当前的检测功率进行调整，从而保证检测设备能够以较小的功率获取到满足需要的采样信号，既保证了检测结果的可信度又节约了资源。In the embodiment provided by the present application, when detecting the blood oxygen or other target items of the human body, the detecting device first acquires the current detection power set by the detecting device for the target item to be detected; and obtains the current detection power.

Skewness＝sum((I-mean(I)/std(I))^3)Skewness=sum((I-mean(I)/std(I))^3)
Kurtosis＝sum((I-mean(I)/std(I))^4)Kurtosis=sum((I-mean(I)/std(I))^4)
Perfusion＝mean(I_max-I_min)/mean(I)Perfusion=mean(I_max-I_min)/mean(I)
其中：I为光照光强，Mean(I)为反射光强度的均值，Std(I)为反射光强度的方差值(Standard deviation)。Where: I is the intensity of the illumination, Mean (I) is the mean of the intensity of the reflected light, and Std (I) is the variance of the intensity of the reflected light.

If it is reached, it determines that it is qualified, and then determines the evaluation value of the current sampling signal.
例如，计算波形偏度的特征值的评分为T1，而其预设评分为T2，若T1>T2，则判定该项特征值合格，根据最终合格特征值与不合格特征值的数量计算本次采样信号的评估值。For example, the score of the characteristic value of the waveform skewness is calculated as T1, and the preset score is T2.
