Technical Field

[0002] As people's living standards continue to improve, the demand for health management becomes more urgent. In the fast-paced modern life, people expect to understand their physical condition anytime and anywhere so as to adjust their lifestyle and prevent diseases in time. Smart bracelets, as a portable personal health and fitness tracker, have become an indispensable part of people's daily life. They can monitor users' sleep quality, heart rate changes and other physiological parameters, and display this information to users through built-in or external displays.

[0003] Traditional smart bracelets have a single function in data collection, and often only focus on single or a few types of physiological data. For data transmission, they often use wired transmission or wireless transmission such as low-version Bluetooth, which restricts the user's freedom of movement. In addition, the transmission rate is slow and the distance is limited. It is impossible to transmit the collected data to external devices in real time, making it difficult to accurately reflect the body's true state and lacking dynamic adjustment feedback.

[0078] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0079] See also Figure 1 The present invention provides a wireless control system for a smart bracelet, comprising:

[0080] The data acquisition module is used to collect the user's heart rate data, blood pressure data, sleep data and blood oxygen data based on the smart bracelet.

[0081] In the above solution, by collecting the user's heart rate data, blood pressure data, sleep data and blood oxygen data based on the smart bracelet, the body information is captured in multiple dimensions, allowing users to understand their physical condition more accurately and comprehensively, and discover potential health problems in time, greatly improving the convenience and efficiency of health monitoring.

[0082] The data transmission module is used to input the data collected by the data acquisition module into the supporting external equipment by using wireless communication.

[0084] The data calculation module is used to calculate the heart rate health index SDH based on the heart rate data.

[0085] The blood pressure stability index BSI is calculated based on the blood pressure data; the blood pressure health index BSQ is calculated based on the blood pressure stability index BSI.

[0086] The sleep recovery effect index SRE and the sleep rhythm disorder index SDQ are calculated based on the sleep data; the sleep health index SXZ is calculated based on the sleep recovery effect index SRE and the sleep rhythm disorder index SDQ.

[0087] The blood oxygen stability index HSI and the blood oxygen reserve capacity index RAI are calculated based on the blood oxygen data; the blood oxygen energy efficiency index NJH is calculated based on the blood oxygen stability index HSI and the blood oxygen reserve capacity index RAI; the blood oxygen health index NHG is calculated based on the blood oxygen stability index HSI, the blood oxygen reserve capacity index RAI and the blood oxygen energy efficiency index NJH.

[0088] Specifically, the method for calculating the heart rate health index SDH is:

[0089] Heart rate data includes heart rate value HRI after exercise i , heart rate value HRE before exercise and heart rate value HRJ during exercise j .

[0090] It should be noted that the heart rate value HRI after exercise i represents the heart rate value at the i-th time point after exercise, which is obtained by measuring the heart rate at different time points after the exercise. For example, the heart rate is measured at 1 minute, 2 minutes, 3 minutes, etc. after the exercise stops using a smart bracelet. The heart rate value before exercise HRE represents the resting heart rate value before exercise, which is obtained by monitoring the bracelet before the exercise starts. The heart rate value during exercise HRJ jIt represents the heart rate value at the jth time point during exercise. The heart rate is measured by the smart bracelet at different time points during exercise. For example, the heart rate is measured every 10 seconds during running.

[0091] The heart rate health index SDH is calculated based on the heart rate data according to the following formula:

[0092] ;

[0093] Among them, HRI i is the heart rate value at the i-th time point after exercise, HRJ j is the heart rate value at the jth time point during exercise, HRJ j+1 is the heart rate value at the j+1th time point during exercise, measured by HRJ j The heart rate value of the next adjacent time point is obtained; i is the serial number corresponding to different time points after exercise, and its value is [1, n]; n is the number of time points after exercise, and its value is a positive integer; j is the serial number corresponding to different time points during exercise, and its value is [1, m]; m is the number of time points during exercise, and its value is a positive integer.

[0094] It should be noted that in this formula: It measures the degree of deviation between the heart rate recovery after exercise and the heart rate before exercise. It is a measure of the intensity of heart rate changes during exercise. The cumulative sum of the ratio of the sum of the squares of the heart rate differences at adjacent times during exercise to the squares of the corresponding heart rate values ​​is calculated, which reflects the heart rate fluctuations during exercise. The overall deviation of the heart rate after exercise from the heart rate before exercise and the severity of the heart rate changes during exercise are considered comprehensively.

[0095] Specifically, the method for calculating the blood pressure stability index BSI is:

[0096] Blood pressure data includes measured blood pressure values ​​BPI k And the mean blood pressure value BGY.

[0097] It should be noted that the measured blood pressure value BPI k represents the blood pressure value measured for the kth time, which is obtained by measuring the user through a smart bracelet. For example, a blood pressure value is obtained each time, and these values ​​are numbered BPI1, BPI2, ..., BPI in the order of measurement. t The average blood pressure value BGY represents the average value of all blood pressure value pairs measured, and the blood pressure values ​​BPI measured multiple times are k (k=1, 2, ..., t) and then divide it by the number of measurements t to obtain it.

[0098] The blood pressure stability index (BSI) is calculated based on the blood pressure data according to the following formula:

[0099] ;

[0100] Among them, BPI k is the blood pressure value measured for the kth time, k is the serial number corresponding to different measurement times, and its value is [1, t]; t is the number of measurements, and its value is a positive integer.

[0101] It should be noted that in this formula: Indicates the blood pressure value BPI for each measurement k The square of the difference between the measured blood pressure value and the average blood pressure value BGY is summed. This sum reflects the total degree of deviation between each measured blood pressure value and the average blood pressure value. Indicates the degree of deviation from the average, and then squares it A quantity reflecting the amplitude of blood pressure fluctuation is obtained, with a numerator of 1, which plays a fixed numerator role in the whole formula; the blood pressure stability index BSI measures the stability of blood pressure by comparing the degree of deviation between the blood pressure value measured each time and the average blood pressure value. The smaller the deviation between the blood pressure value measured each time and the average value, the smaller the denominator, the larger the BSI value, indicating that the blood pressure is more stable; conversely, the greater the fluctuation of blood pressure values, the larger the denominator, the smaller the BSI value, indicating that the blood pressure stability is worse.

[0102] Specifically, the method for calculating the blood pressure health index BSQ is:

[0103] The blood pressure health index BSQ is calculated based on the blood pressure stability index BSI, and the formula is as follows:

[0104] ;

[0105] Among them, α is the weight coefficient of the blood pressure stability index BSI, which is determined according to the influence of the blood pressure stability index BSI on the blood pressure health index BSQ, and its value ranges from 0 to 1.

[0106] It should be noted that in this formula: the first "1" is a constant term, which serves as a benchmark in the entire calculation process. After weighting the BSI, the natural exponent e is raised to the power, and the denominator is obtained by adding 1 to the value of the exponential part to obtain a value greater than 1 for fraction calculation; in general, the BSQ value range is between 0 and 1. When the value of BSI makes the fractional term When the score item is close to 0, BSQ is close to 1, indicating that the blood pressure health status is good; when the score item is close to 1, BSQ is close to 0, indicating that the blood pressure health status is poor.

[0107] Specifically, the method for calculating the sleep recovery effect index SRE and the sleep rhythm disorder index SDQ is as follows:

[0108] Sleep data includes the total duration of deep sleep DET for the whole night, the total sleep duration SIE for the whole night, and the number of sleep interruptions INM.

[0109] It should be noted that the total duration of deep sleep for the whole night DET indicates the duration of deep sleep for the whole night, which is measured by a smart bracelet; the total sleep time for the whole night SIE indicates the sleep time from going to bed at night to getting up in the morning, which is measured by a smart bracelet, and the duration of the entire period from the user falling asleep to waking up is obtained; the number of sleep interruptions INM indicates the number of wake-ups throughout the night, which is detected by the smart bracelet through the user's body movements during sleep to determine whether the user has sleep interruptions such as short wake-ups, and counted.

[0110] The sleep recovery effect index SRE is calculated based on the total duration of deep sleep DET throughout the night, the total sleep duration SIE throughout the night, and the number of sleep interruptions INM. The formula is as follows:

[0111] ;

[0112] Among them, β1 is The weight coefficient is based on The influence degree on the sleep recovery effect index SRE is determined, and the value is 0.2~0.5; β2 is The weight coefficient is based on The degree of influence on the sleep recovery effect index SRE is determined, with a value of 0.5~0.8; and β1+β2=1.

[0113] It should be noted that in this formula: It reflects the proportion of deep sleep. The effects of total sleep duration and sleep interruptions on sleep recovery effect are comprehensively considered. The longer the total sleep duration, the smaller the value of this part; the more sleep interruptions, the larger the value of this part; the effects of deep sleep duration, total sleep duration and sleep interruptions on sleep recovery effect are comprehensively considered. The longer the deep sleep duration, the longer the total sleep duration and the fewer the sleep interruptions, the smaller the denominator and the larger the SRE value, indicating that the sleep recovery effect is better; conversely, the larger the denominator, the smaller the SRE value, indicating that the sleep recovery effect is worse.

[0114] Sleep data also includes the duration of sleep cycles CYI x and the average duration of a normal sleep cycle CYE.

[0115] It should be noted that the duration of the sleep cycle is xIt represents the duration of the x-th sleep cycle. The smart bracelet monitors the user's body movements and other physiological signals to determine the different stages of the user's sleep state, and then divides the sleep cycle and records the duration of each cycle. The average duration of a normal sleep cycle is CYE, which is obtained through statistics based on sleep data of a large number of people.

[0116] According to the length of sleep cycle CYI x The sleep rhythm disorder index SDQ is calculated based on the average duration of the normal sleep cycle CYE, and the formula is as follows:

[0117] ;

[0118] Among them, CYI x is the duration of the x-th sleep cycle, x is the serial number corresponding to different sleep cycles, and its value is [1, f]; f is the number of sleep cycles, and its value is a positive integer.

[0119] It should be noted that in this formula: It is the sum of the squares of the differences between the duration of each sleep cycle and the average duration of a normal sleep cycle, reflecting the total degree of deviation between the duration of each sleep cycle and the average duration of a normal sleep cycle. The denominator f plays a normalization role, so that the index can be within a reasonable range. The numerator and denominator are divided, and then the square root is taken to obtain the sleep rhythm disorder index, which comprehensively reflects the degree of discreteness of the sleep cycle duration relative to the average duration of a normal sleep cycle. The larger the index, the more disordered the sleep rhythm.

[0120] Specifically, the method for calculating the sleep health index SXZ is:

[0121] The sleep health index SXZ is calculated based on the sleep recovery effect index SRE and the sleep rhythm disorder index SDQ. The formula is as follows:

[0122] ;

[0123] Among them, δ1 is the weight coefficient of the sleep recovery effect index SRE, which is determined according to the influence of the sleep recovery effect index SRE on the sleep health index SXZ, and its value is 0.1~0.3; δ2 is the weight coefficient of the sleep rhythm disorder index SDQ, which is determined according to the influence of the sleep rhythm disorder index SDQ on the sleep health index SXZ, and its value is 0.7~0.9; and δ1+δ2=1.

[0124] It should be noted that in this formula: It reflects the impact of the sleep recovery effect index on the sleep health index. Multiplying it by the corresponding weight coefficient adjusts the contribution of the sleep recovery effect index to the sleep health index. It reflects the impact of the sleep rhythm disorder index on the sleep health index. The contribution of the sleep rhythm disorder index to the sleep health index is adjusted by multiplying it by the corresponding weight coefficient. The two are added and the square root is taken to get the sleep health index SXZ. Among them, the square root mainly plays a role in adjusting the data range to make it more in line with practical significance and facilitate comparison. The sleep health index is calculated by comprehensively considering the sleep recovery effect index and the sleep rhythm disorder index. When SRE is higher and SDQ is lower, the value of the sleep health index SXZ is higher, indicating that the sleep health condition is better; conversely, when SRE is lower and SDQ is higher, the value of the sleep health index SXZ is lower, indicating that the sleep health condition is poor.

[0125] Specifically, the method for calculating the blood oxygen stability index HSI and the blood oxygen reserve capacity index RAI is:

[0126] Blood oxygen data includes the blood oxygen saturation value SPL at rest g , blood oxygen saturation standard value SDP, blood oxygen perfusion value PIK g And blood oxygen perfusion standard value PKM.

[0127] It should be noted that the blood oxygen saturation value SPL at rest g Indicates the blood oxygen saturation value measured for the gth time, which is obtained by performing multiple measurements on the user through the smart bracelet. For example, a blood oxygen saturation value is obtained each time the measurement is performed. These values ​​are numbered SPL1, SPL2, ..., SPL z ; Blood oxygen saturation standard value SDP represents the reference blood oxygen saturation value, which is determined by normal blood oxygen saturation data based on medical research; Blood oxygen perfusion value PIK g It indicates the blood oxygen perfusion value measured for the gth time, which is obtained by performing multiple measurements on the user through the smart bracelet; the blood oxygen perfusion standard value PKM indicates the reference value for comparison, which is usually determined by medical research and is used to measure whether the actually measured blood oxygen perfusion value is normal.

[0128] According to the blood oxygen saturation value SPL g , blood oxygen saturation standard value SDP, blood oxygen perfusion value PIK g The blood oxygen stability index HSI is calculated based on the blood oxygen perfusion standard value PKM, and the formula is as follows:

[0129] ;

[0130] Among them, SPL g is the blood oxygen saturation value measured for the gth time, PIK g is the blood oxygen perfusion value measured for the gth time, g is the serial number represented by different measurement times, and its value is [1, z]; z is the measurement number, and its value is a positive integer.

[0131] It should be noted that in this formula: The sum of the difference between the blood oxygen perfusion value and the standard value of blood oxygen perfusion and the difference between the blood oxygen saturation value and the standard value of blood oxygen saturation reflects the comprehensive deviation of the blood oxygen perfusion value and the blood oxygen saturation value relative to their respective standard values. The square of the difference between each measured blood oxygen perfusion value and the standard value of blood oxygen perfusion is summed up, reflecting the total degree of deviation of the blood oxygen perfusion value relative to the standard value. The square of the difference between the blood oxygen saturation value measured each time and the standard value of the blood oxygen saturation is summed, reflecting the total degree of deviation of the blood oxygen saturation value from the standard value. The two are multiplied and the square root is taken to obtain the denominator, and the numerator and denominator are divided to obtain the blood oxygen stability index HSI. The stability of blood oxygen is measured by comprehensively considering the deviation of the blood oxygen perfusion value and the blood oxygen saturation value from their respective standard values. The larger the value of the numerator, that is, the greater the deviation of the blood oxygen perfusion value and the blood oxygen saturation value from the standard value, the smaller the value of HSI, indicating that the blood oxygen stability is worse; conversely, the smaller the value of the numerator, the larger the value of HSI, indicating that the blood oxygen stability is better.

[0132] The blood oxygen data also includes the maximum value SPM of blood oxygen saturation in exercise state, the average value SPR of blood oxygen saturation in resting state, the average value PLU of blood oxygen perfusion in exercise state, the average value PKJ of blood oxygen perfusion in resting state and the average blood oxygen saturation DFS in comprehensive state.

[0133] It should be noted that the maximum value of blood oxygen saturation SPM in the exercise state represents the maximum value of blood oxygen saturation during exercise, which is obtained by monitoring with a smart bracelet when the user is exercising; the average value of blood oxygen saturation SPR in the resting state represents the average value of blood oxygen saturation when the user is in a quiet resting state such as sitting still, sleeping, etc., which is obtained by continuously measuring the blood oxygen saturation with a smart bracelet and calculating its average value; the average value of blood oxygen perfusion PLU in the exercise state represents the average value of blood oxygen perfusion during the user's exercise, which is obtained by continuously measuring the blood oxygen perfusion value with a smart bracelet and calculating its average value; the average value of blood oxygen perfusion PKJ in the resting state represents the average value of blood oxygen perfusion in the user's resting state, which is obtained by continuously measuring the blood oxygen perfusion value with a smart bracelet and calculating its average value; the average blood oxygen saturation DFS in the comprehensive state represents the average blood oxygen saturation value obtained by comprehensive measurement and calculation of blood oxygen saturation in exercise and resting states, which is obtained by multiple measurements of blood oxygen saturation values ​​in exercise and resting states and calculating their average value.

[0134] The blood oxygen reserve capacity index RAI is calculated based on the maximum blood oxygen saturation SPM in the exercise state, the average blood oxygen saturation SPR in the resting state, the average blood oxygen perfusion PLU in the exercise state, the average blood oxygen perfusion PKJ in the resting state and the average blood oxygen saturation DFS in the comprehensive state. The formula is as follows:

[0135] ;

[0136] It should be noted that in this formula: the numerator consists of two parts, the first part The difference between the maximum value of blood oxygen saturation in the exercise state and the average value of blood oxygen saturation in the resting state, the second part It represents the difference between the average blood oxygen perfusion value under exercise and the average blood oxygen perfusion value under rest. The numerator as a whole reflects the comprehensive changes of blood oxygen saturation and blood oxygen perfusion value under different states; the denominator It reflects the product of the blood oxygen saturation under the comprehensive state and the average blood oxygen perfusion under the resting state. The numerator is divided by the denominator and then the square root is taken to obtain the blood oxygen reserve capacity index RAI, which reflects the comprehensive situation of the human body's blood oxygen reserve and regulation ability under different states.

[0137] Specifically, the method for calculating the blood oxygen energy efficiency index NJH is:

[0138] The blood oxygen energy efficiency index NJH is calculated based on the blood oxygen stability index HSI and the blood oxygen reserve capacity index RAI. The formula is as follows:

[0139] ;

[0140] It should be noted that in this formula: The multiplication of the two takes into account the stability and reserve capacity of blood oxygen. It reflects the difference between the blood oxygen stability index and the blood oxygen reserve capacity index. It reflects the consistency between the blood oxygen stability index HSI and the blood oxygen reserve capacity index RAI. The square root in the formula is to make the value of NJH within a more reasonable range, which is convenient for quantifying and comparing blood oxygen energy efficiency. It comprehensively considers the stability and reserve capacity of blood oxygen and their relationship to measure the blood oxygen energy efficiency of the human body.

[0141] Specifically, the method for calculating the blood oxygen health index NHG is:

[0142] The blood oxygen health index NHG is calculated based on the blood oxygen stability index HSI, the blood oxygen reserve capacity index RAI and the blood oxygen energy efficiency index NJH. The formula is as follows:

[0143] ;

[0144] Among them, γ1 is the weight coefficient of the blood oxygen stability index HSI, which is determined according to the influence of the blood oxygen stability index HSI on the blood oxygen health index NHG, and its value is 0.1~0.3; γ2 is the weight coefficient of the blood oxygen reserve capacity index RAI, which is determined according to the influence of the blood oxygen reserve capacity index RAI on the blood oxygen health index NHG, and its value is 0.3~0.4; γ3 is the weight coefficient of the blood oxygen energy efficiency index NJH, which is determined according to the influence of the blood oxygen energy efficiency index NJH on the blood oxygen health index NHG, and its value is 0.4~0.5; and γ1+γ2+γ3=1.

[0145] It should be noted that in this formula: the blood oxygen health index is calculated by comprehensively considering the blood oxygen stability index, blood oxygen reserve capacity index and blood oxygen energy efficiency index and multiplying them by the corresponding weight coefficients. When the value of the blood oxygen health index is higher, it means that the blood oxygen health status is better; conversely, when the value of the blood oxygen health index is lower, it means that the blood oxygen health status is poor.
