Based on the hardware structure of the equipment, the embodiment of the heart rate detection method is provided.
Referring to fig. 2, in a first embodiment of the heart rate detection method of the present invention, the heart rate detection method includes:
and step S10, judging whether the wearing part corresponding to the heart rate detection equipment is the human skin or not according to the sound wave emitted by the ultrasonic sensor and the received sound wave.
The heart rate detection method in this embodiment is applied to heart rate detection equipment, for example, a smart watch and a smart bracelet, the heart rate detection equipment at least comprises a heart rate detection module and an ultrasonic sensor, the heart rate detection module can detect heart rate by emitting light and receiving light, the ultrasonic sensor is used for acquiring the distance between the heart rate detection equipment and a wearing part, and therefore, as long as the current heart rate module only presents heart rate detection results according to physical conditions and a preset algorithm, as long as a detected object is a good reflector of optical signals, regular changes of the reflected optical signals can be fitted into the heart rate by continuously shaking and extruding the detected object, that is, the phenomenon that the heart rate can be detected also exists in other objects (such as toilet roll paper, water bottle, plush toy and the like) is measured, therefore, the embodiment first measures sound waves and received sound waves according to the ultrasonic sensor, and judging whether the wearing part corresponding to the heart rate detection equipment is in contact with human skin or not.
And step S20, if the wearing part is human skin, acquiring a target distance between the heart rate detection module and the human skin.
If what wear the position contact with heart rate check out test set corresponds is human skin, then ultrasonic sensor acquires human skin and heart rate and detects the distance between the module, can know, ultrasonic sensor and the adjacent setting in heart rate detection module position, the purpose is the distance value who guarantees ultrasonic sensor and acquire, be promptly user's skin with distance (being the target distance in this embodiment) between the heart rate detection module, can understand, because structural design scheduling problem leads to ultrasonic sensor and heart rate to detect when the module position sets up not closely, still need handle the distance value that ultrasonic sensor acquireed, just can turn into the target distance with the distance value that ultrasonic sensor acquireed, concrete processing method is related to with the position that ultrasonic sensor and heart rate detection module set up.
And step S30, if the target distance belongs to a preset interval, starting the heart rate detection module, and acquiring first emission light corresponding to the target distance.
Know ground, the target distance is the distance between the heart rate detection module group in skin and the intelligent wrist-watch of the user who uses intelligent wrist-watch promptly, because the intelligent wrist-watch in this embodiment adopts the method of light detection heart rate, specific process is as follows: the heart rate detects the module and beats light on user's skin, when the heart pump blood, blood can be full of in the blood vessel below the skin, and blood absorbs green glow reflection red light, the heart can produce the different light reflection of colour when contraction and diastole, the heart rate detects the module just through detecting the reverberation that these colours are different and detect user's heart rate, therefore, heart rate in this embodiment detects the module and is very easily influenced by external light and the blood flow condition, the user needs correctly to wear when using intelligent wrist-watch, can not wear too loosely to lead to the light leak, also can not wear too tightly to lead to the blood circulation not smooth and easy, and the target distance in this embodiment is the distance between user's skin and the heart rate detection module that uses intelligent wrist-watch, the target distance is big more, it is pine more to explain that the user wears intelligent wrist-watch, when the user wears intelligent wrist-watch loose certain degree, just can's heart rate can, the user wears the smart watch to a certain degree, a distance value (between the skin of the user and the heart rate detection module) is set, for example, 5 millimeters, the preset interval is 0-5 millimeters, when the acquired target distance is 0-5 millimeters, the heart rate detection module can detect the heart rate of the user, and under the condition, the heart rate detection program starts the heart rate detection module; when the target distance who acquires is greater than 5 millimeters (do not belong to preset interval promptly), show that heart rate detection module can't detect user's heart rate, under this kind of condition, heart rate detection program just does not respond heart rate detection instruction, stops to start heart rate detection module, has played the effect that the suggestion user correctly wore intelligent wrist-watch to a certain extent.
After starting heart rate detection module, because user's skin and heart rate detect and have certain distance between the module, ambient light can cause certain influence to heart rate detection, consequently, need according to the size of target distance, confirms the transmission light of heart rate detection module (the first transmission light in this embodiment promptly), specifically how to confirm first transmission light according to target distance, will detail in the following.
Step S40, controlling the heart rate detection module to emit the first emitting light, and receiving a first reflected light corresponding to the first emitting light.
Therefore, the heart rate detection module has functions of Emitting Light and receiving Light, after the first Emitting Light is determined according to the target distance, the heart rate detection module emits the first Emitting Light to the skin of the user, and receives the Light (i.e., the first reflecting Light in the embodiment) reflected by the skin of the user, it can be understood that the smart watch further has functions of obtaining Light intensity and adjusting the Light intensity according to the heart rate detection principle, for example, the Light intensity of the Emitting Light is adjusted by adjusting the current flowing through an LED (Light Emitting Diode) lamp, and therefore, when the current flowing through the LED lamp is reduced, the Light intensity of the Emitting Light of the LED lamp is reduced; when the current flowing through the LED lamp is increased, the light intensity of the light emitted by the LED lamp is increased, a certain contrast relation is also formed between the target distance and the light intensity of the emitted light, and when the target distance is increased, the influence of external light is increased; when the target distance becomes smaller, the influence of the external light becomes smaller, and in this case, the light intensity of the emitted light is reduced by reducing the current flowing through the LED lamp, and the reduced light intensity is taken as the light intensity of the first emitted light.
Step S50, determining the heart rate obtained by the heart rate detection equipment according to the light intensity of the first reflected light and the light intensity of the first reflected light.
It is understood that the method used for heart rate detection in this embodiment may be PPG
The photoplethysmography method is characterized in that an LED light source in a heart rate detection module emits first emitting light to the skin of a user, the first emitting light (light signal) is converted into an electric signal through a photoelectric receiving tube in the heart rate detection module, the proportion of oxygen-containing red blood cells in blood shows periodic change along with the contraction and the relaxation of the heart due to the fact that the blood flow rate shows periodic rule along with the contraction and the relaxation of the heart, the absorption degree of the first emitting light by the blood shows periodic change along with the contraction and the relaxation of the heart, the electric signal converted by the photoelectric receiving tube shows periodic change along with the contraction and the relaxation of the heart is demodulated, and the first emitting light is transmitted to the photoelectric receiving tube through the photoelectric receiving tube, finally, the pulse rate of the user is calculated, and the pulse rate is equal to the heart rate.
Specifically, the step of step S10 refinement includes:
step a1, obtaining the intensity of the sound wave transmitted by the ultrasonic sensor and the intensity of the received sound wave, and calculating the wave intensity difference between the transmitted sound wave intensity and the received sound wave intensity.
Step a2, searching for a substance corresponding to the wave intensity difference in a preset substance comparison table, and judging whether the wearing part corresponding to the heart rate detection equipment is human skin or not according to the substance corresponding to the wave intensity difference.
It can be known that, after receiving a heart rate detection instruction, a heart rate detection program firstly determines whether a user wears the smart watch through the ultrasonic sensor (the arm of the user), and practice shows that, when the smart watch is worn on non-human tissues such as a water bottle, the heart rate can be detected, which may cause a feeling that the heart rate measurement does not depend on the spectrum to the user, in order to avoid this, in this embodiment, when receiving the heart rate detection instruction, the sound wave is further emitted through the sound wave emitting unit in the ultrasonic sensor to obtain the intensity of the emitted sound wave, when the intensity of the emitted sound wave is constant, it may be determined which material surface the sound wave is incident from the air, specifically, under the condition that the intensity of the emitted sound wave is constant, if the acoustic impedance difference between the two materials is larger, the intensity of the reflected sound wave is larger, in this embodiment, one material is air, and whether the other material is human skin needs to be verified, under the condition, the intensity of the emitted sound wave is ensured to be constant, the air is constant, the sound wave intensity difference between the intensity of the emitted sound wave and the intensity of the received sound wave is calculated, if the sound wave intensity difference is larger, the acoustic impedance of the other material is smaller, if the sound wave intensity difference is smaller, the acoustic impedance of the other material is larger, accordingly, whether the other material is human skin can be judged, specifically, by inquiring a wave intensity difference and substance comparison table corresponding to the intensity of the emitted sound wave, a substance (namely, a target substance in the embodiment) corresponding to the wave intensity difference and the sound wave intensity difference in the substance comparison table is inquired, and if the target substance is human skin, the wearing part corresponding to the heart rate detection device is judged to be human skin.
Specifically, the step of step S20 refinement includes:
and b1, if the wearing part is the skin of the human body, acquiring the time of the ultrasonic sensor for transmitting the sound wave and the time of receiving the sound wave.
And b2, calculating the target distance between the heart rate detection equipment and the human skin according to the time for transmitting the sound waves and the time for receiving the sound waves.
The sound wave transmitted back by the transmitted sound wave is received through the sound wave receiving unit in the ultrasonic sensor, namely the received sound wave in the embodiment, the intensity of the received sound wave is obtained, the time difference between the sound wave transmitting time and the sound wave receiving time is calculated according to the principle of sound wave distance measurement, then the sound velocity is multiplied by the time difference, the obtained product is divided by two, so that a distance value is obtained, the distance value obtained by the ultrasonic sensor is not necessarily the target distance between the skin of a user and the heart rate detection module, before that, the material surface to which the sound wave is incident from the air is determined according to the intensity of the transmitted sound wave and the intensity of the received sound wave, specifically, the reflected sound waves with different intensities are generated when the sound wave is incident from the air to the surface of the skin of a human body according to the definition of acoustic impedance, so that the intensity of the reflected sound wave generated when the sound wave is incident from the air, and determining whether the distance value obtained by the ultrasonic sensor is the target distance between the skin surface of the user and the heart rate detection module or not according to the intensity of the transmitted sound wave and the intensity of the received sound wave.
Specifically, the step of step S20 refinement includes:
and c1, determining the distance error according to the ultrasonic sensor and the heart rate detection module.
And c2, calculating the distance value obtained by the ultrasonic sensor and the distance error to obtain the target distance between the heart rate detection equipment and the human skin.
It can be known that, because of the need of the structural design of the smart watch, the ultrasonic sensor and the heart rate detection module are not necessarily located at the same position, the heart rate detection module is generally arranged on the convex structure of the lower shell of the smart watch, so that the heart rate detection module is more easily attached to the skin of the human body, and if the ultrasonic sensor is not arranged on the convex structure together with the heart rate detection module, the distance value obtained by the ultrasonic sensor is processed to obtain the target distance between the heart rate detection module and the skin of the user, specifically, when the ultrasonic sensor is not arranged on the convex structure together with the heart rate detection module, the distance error is determined according to the positions of the ultrasonic sensor and the heart rate detection module, then the distance value obtained by the ultrasonic sensor is subtracted by the distance error, so that the target distance can be obtained, it can be known, when the distance value acquired by the ultrasonic sensor is smaller than the distance error, the fact that the user wears the intelligent watch too tightly is indicated, and under the condition, the fact that the user wears the intelligent watch too tightly can be prompted through vibration.
Specifically, the step of step S30 refinement includes:
and d1, acquiring the ambient light information, and inquiring a preset light intensity comparison table corresponding to the ambient light information.
