请参照图2，图2为本申请实施例提供的应用于图1中的心率检测设备100的心率检测方法的流程图之一。所述方法包括以下步骤：Please refer to FIG. 2 , which is one of the flowcharts of a heart rate detection method applied to the heartrate detection device 100 in FIG. 1 according to an embodiment of the present application. The method includes the following steps:

步骤S210，通过心电信号检测单元获取用户的心电信号。Step S210, acquiring the user's ECG signal through the ECG signal detection unit.

步骤S220，通过光电容积检测单元获取用户的PPG信号。Step S220, the user's PPG signal is acquired through the photoelectric volume detection unit.

步骤S230，根据心电信号及PPG信号分析得到综合信号。In step S230, a comprehensive signal is obtained by analyzing the ECG signal and the PPG signal.

步骤S240，根据综合信号计算用户的心率。Step S240, calculating the heart rate of the user according to the integrated signal.

可选地，在本实施例中，心率检测设备100包括心电信号检测单元、光电容积检测单元。其中，心电信号检测单元用于实时采集用户的心电信号，光电容积检测单元用于实时采集用户的PPG信号(光电容积脉搏信号)。Optionally, in this embodiment, the heartrate detection device 100 includes an electrocardiogram signal detection unit and a photovolume detection unit. The electrocardiographic signal detection unit is used to collect the user's electrocardiographic signal in real time, and the photoelectric volume detection unit is used to collect the user's PPG signal (photoplethysmography signal) in real time.

可选地，在本实施例中，步骤S220具体包括：通过光电容积检测单元，根据检测到的用户的血管的收缩或扩张情况生成用户的PPG信号。Optionally, in this embodiment, step S220 specifically includes: generating the user's PPG signal according to the detected constriction or dilation of the user's blood vessel through the photoelectric volume detection unit.

具体地，在本实施例中，外周血管中的微动脉、毛细血管和微静脉内流过的血液会随着心脏的搏动相应的呈脉动性变化。当心脏收缩时血液容积最大，而在心脏舒张时血液容积最小。采用一定波长的光束照射到指端或手腕的皮肤表面时，光束将通过透射或反射方式传送到光电接收器。皮肤内的血液容积在心脏收缩舒张作用下呈搏动性变化，当心脏收缩时外周血管血容量最多，光吸收量也最大，检测到的光强度最小；在心脏舒张时，正好相反，外周血管血容量最少，检测到的光强度最大，使光电接收器检测到的光强度随之呈脉动性变化，将该变化的光强度信号转换为电信号即可获得用户的PPG信号。Specifically, in this embodiment, the blood flowing through the arterioles, capillaries, and venules in the peripheral blood vessels changes pulsatilely with the beating of the heart. The blood volume is greatest when the heart is systole and the least when the heart is diastolic. When a light beam of a certain wavelength is irradiated on the skin surface of the finger end or wrist, the light beam will be transmitted to the photoelectric receiver through transmission or reflection. The blood volume in the skin changes pulsatilely under the action of cardiac systole and relaxation. When the heart contracts, the peripheral blood volume is the largest, the light absorption is also the largest, and the detected light intensity is the smallest. With the least capacity, the detected light intensity is the largest, so that the light intensity detected by the photoelectric receiver changes pulsatingly, and the changed light intensity signal is converted into an electrical signal to obtain the user's PPG signal.

目前，可以单独分析用户的PPG信号从而计算获得用户的心率，但容易受到环境光线的影响从而导致检测结果出现误差。At present, the user's PPG signal can be analyzed separately to obtain the user's heart rate, but it is easily affected by ambient light, resulting in errors in the detection results.

同时，心电信号也可单独用于计算用户的心率，但由于心电信号的信号幅度小，经常会被呼吸、脉搏等噪声所影响。因此，单独使用心电信号测量用户的心率也会导致检测结果不准确。At the same time, the ECG signal can also be used alone to calculate the user's heart rate, but because the signal amplitude of the ECG signal is small, it is often affected by noises such as breathing and pulse. Therefore, using the ECG signal alone to measure the user's heart rate will also lead to inaccurate detection results.

在上述步骤S210至步骤S240中，首先分别通过心电信号检测单元及光电容积检测单元分别获得用户的心电信号及PPG信号，随后通过分析心电信号及PPG信号获得综合信号，通过该综合信号计算用户的心率。In the above steps S210 to S240, the user's ECG signal and PPG signal are obtained respectively through the ECG signal detection unit and the photovolume detection unit, respectively, and then a comprehensive signal is obtained by analyzing the ECG signal and the PPG signal, and the comprehensive signal is obtained by analyzing the ECG signal and the PPG signal. Calculate the user's heart rate.

通过联合分析心电信号及PPG信号以计算用户的心率，不仅可以有效地解决光线对光电容积法测量用户的心率的干扰，也可以解决心电信号法容易受到呼吸、脉搏或电磁干扰的问题，在一定程度上避免检测结果出现的误差，提高心率检测设备100检测结果的准确率。By jointly analyzing the ECG signal and PPG signal to calculate the user's heart rate, it can not only effectively solve the interference of light on the measurement of the user's heart rate by photoplethysmography, but also solve the problem that the ECG signal method is susceptible to breathing, pulse or electromagnetic interference. To a certain extent, errors in the detection results are avoided, and the accuracy of the detection results of the heartrate detection device 100 is improved.

可选地，在本实施例中，心率检测设备100还可以包括加速度传感器，加速度传感器用于放大综合信号，以便计算实时心率。加速度传感器还可以用于去除高频噪声，提升心率测量值的准确度。Optionally, in this embodiment, the heartrate detection device 100 may further include an acceleration sensor, and the acceleration sensor is used to amplify the integrated signal, so as to calculate the real-time heart rate. Accelerometers can also be used to remove high-frequency noise and improve the accuracy of heart rate measurements.

可选地，在本实施例中，心率检测设备100还可以包括电压检测单元及稳压单元。其中电压检测单元用于检测心率检测设备100的输入电压，并判断该输入电压是否恒定，若输入电压不恒定，则通过稳压单元保持输入电压的恒定，防止由于输入电压不足造成的心率测量结果不准确。Optionally, in this embodiment, the heartrate detection device 100 may further include a voltage detection unit and a voltage stabilization unit. The voltage detection unit is used to detect the input voltage of the heartrate detection device 100 and determine whether the input voltage is constant. If the input voltage is not constant, the voltage stabilization unit will keep the input voltage constant to prevent heart rate measurement results due to insufficient input voltage. Inaccurate.

可选地，请参照图3，图3为本申请实施例提供的图2中的步骤S230的子步骤流程图。在本实施例中，步骤S230包括以下子步骤：Optionally, please refer to FIG. 3 , which is a flowchart of sub-steps of step S230 in FIG. 2 provided by this embodiment of the present application. In this embodiment, step S230 includes the following sub-steps:

子步骤S2301，根据心电信号对应的第一权重及PPG信号对应的第二权重对心电信号及PPG信号加权求和，以获得综合信号。Sub-step S2301, weighting and summing the ECG signal and the PPG signal according to the first weight corresponding to the ECG signal and the second weight corresponding to the PPG signal to obtain a comprehensive signal.

在本实施例中，心率检测设备100中预存有心电信号对应的第一权重以及PPG信号对应的第二权重，在获得综合信号时，从心率检测设备100中获取第一权重及第二权重，并根据第一权重及第二权重对心电信号及PPG信号加权求和后获得综合信号。In this embodiment, the first weight corresponding to the ECG signal and the second weight corresponding to the PPG signal are pre-stored in the heartrate detection device 100, and when the comprehensive signal is obtained, the first weight and the second weight are obtained from the heartrate detection device 100, The electrocardiographic signal and the PPG signal are weighted and summed according to the first weight and the second weight to obtain a comprehensive signal.

例如，心电信号对应的第一权重可以为40％，PPG信号对应的第二权重可以为60％，根据各自的权重进行加权求和可以获得综合信号。For example, the first weight corresponding to the ECG signal may be 40%, and the second weight corresponding to the PPG signal may be 60%, and a comprehensive signal can be obtained by performing weighted summation according to the respective weights.

可以理解的是，上述的第一权重及第二权重的具体数值是对本实施例的第一权重及第二权重的示例性说明，在本实施例的其他实施方式中，第一权重和第二权重还可以为其他数值，在此不作具体限定。It can be understood that the above-mentioned specific values of the first weight and the second weight are exemplary descriptions of the first weight and the second weight of this embodiment. In other implementations of this embodiment, the first weight and the second weight are The weight can also be other values, which are not specifically limited here.

可选地，在本实施例中，心电信号是一种生物电信号，通过对心电信号进行峰值检测可以获得心率，但通过心电信号测量出来的心率误差较大，因此，心电信号对应的第一权重可以小于PPG信号对应的第二权重。Optionally, in this embodiment, the ECG signal is a bioelectrical signal, and the heart rate can be obtained by performing peak detection on the ECG signal, but the heart rate measured by the ECG signal has a large error. The corresponding first weight may be smaller than the corresponding second weight of the PPG signal.

通过设置第一权重和第二权重，并根据第一权重和第二权重计算综合信号，能够进一步提升心率检测设备100的准确率。By setting the first weight and the second weight, and calculating the comprehensive signal according to the first weight and the second weight, the accuracy of the heartrate detection device 100 can be further improved.

可选地，请参照图4，图4为本申请实施例提供的应用于图1中的心率检测设备100的心率检测方法的流程图之二，在本实施例中，在步骤S240之前，所述方法还包括：Optionally, please refer to FIG. 4. FIG. 4 is the second flow chart of the heart rate detection method applied to the heartrate detection device 100 in FIG. 1 provided by an embodiment of the present application. In this embodiment, before step S240, all The method also includes:

步骤S231，通过ANS算法对综合信号进行降噪处理。Step S231 , perform noise reduction processing on the integrated signal through the ANS algorithm.

当通过对心电信号及PPG信号分析获得综合信号后，还需要对该综合信号进行降噪处理，可选地，在本实施例中，采用ANS(单通道降噪)算法对该综合信号进行降噪处理。使用降噪后的综合信号计算用户的心率能够使得检测结果更加准确，在一定程度上降低心率检测设备100的检测结果出现的误差。After the integrated signal is obtained by analyzing the ECG signal and the PPG signal, it is necessary to perform noise reduction processing on the integrated signal. Noise reduction processing. Using the denoised integrated signal to calculate the user's heart rate can make the detection result more accurate, and reduce errors in the detection result of the heartrate detection device 100 to a certain extent.

可选地，请继续参照图4，在步骤S240之后，所述方法还包括：Optionally, please continue to refer to FIG. 4, after step S240, the method further includes:

步骤S241，将用户的心率与心率检测设备中预存的心率范围进行比较，判断用户的心率是否在预存的心率范围内，若不在预存的心率范围内，则触发报警单元发出报警信息。Step S241, compare the user's heart rate with the heart rate range pre-stored in the heart rate detection device to determine whether the user's heart rate is within the pre-stored heart rate range, if not, trigger the alarm unit to issue an alarm message.
