[0079] Please refer to Figure 1 , the present invention provides a wireless control system for an intelligent bracelet, including:

[0080] A data acquisition module, configured to collect the user's heart rate data, blood pressure data, sleep data, and blood oxygen data based on the intelligent bracelet.

[0084] A data calculation module, configured to calculate the heart rate health index SDH based on the heart rate data.

[0085] Calculate the blood pressure stability index BSI based on the blood pressure data; calculate the blood pressure health index BSQ based on the blood pressure stability index BSI.

[0086] Calculate the sleep recovery effect index SRE and the sleep rhythm disorder index SDQ based on the sleep data; calculate the sleep health index SXZ based on the sleep recovery effect index SRE and the sleep rhythm disorder index SDQ.

[0087] Calculate the blood oxygen stability index HSI and the blood oxygen reserve capacity index RAI based on the blood oxygen data; calculate the blood oxygen energy efficiency index NJH based on the blood oxygen stability index HSI and the blood oxygen reserve capacity index RAI; calculate the blood oxygen health index NHG 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] The heart rate data includes the heart rate value HRI after exercise i , the heart rate value HRE before exercise, and the heart rate value HRJ during exercise j .

[0090] It should be noted that the heart rate value HRI after exercise iThe 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 ends. For example, a smart bracelet is used to measure the heart rate at time points such as 1 minute, 2 minutes, 3 minutes, etc. after the exercise stops; the heart rate value \(HRE\) before exercise represents the resting heart rate value before exercise, which is monitored by the bracelet before the exercise starts; the heart rate value \(HRJ\) during exercise j represents the heart rate value at the \(j\)-th time point during exercise, which is obtained by measuring the heart rate at different time points by a smart bracelet 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, and the formula is as follows:

[0092] ;

[0093] where \(HRI\) i is the heart rate value at the \(i\)-th time point after exercise, \(HRJ\) j is the heart rate value at the \(j\)-th time point during exercise, \(HRJ\) j+1 is the heart rate value at the \((j + 1)\)-th time point during exercise, which is obtained by measuring the heart rate value at the next adjacent time point of \(HRJ\) j ; \(i\) is the serial number corresponding to different time points after exercise, and its value range 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 range 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: measures the degree of deviation of the heart rate recovery after exercise from the heart rate before exercise, measures the severity of the heart rate change during exercise, where calculates the cumulative sum of the ratio of the sum of the squares of the heart rate differences between adjacent time points during exercise to the squares of the corresponding heart rate values, reflecting the heart rate fluctuation during exercise; overall, it comprehensively considers the deviation of the heart rate after exercise from the heart rate before exercise and the severity of the heart rate change during exercise.

[0095] Specifically, the method for calculating the blood pressure stability index \(BSI\) is as follows:

[0096] The blood pressure data includes the measured blood pressure value \(BPI\) k and the average blood pressure value \(BGY\).

[0097] It should be noted that the measured blood pressure value \(BPI\) k represents the blood pressure value measured at the \(k\)-th measurement, which is obtained by measuring the user with a smart bracelet. For example, a blood pressure value is obtained each time, and these values are numbered as \(BPI\) in the measurement order 1, BPI 2 、...、BPI t ; The average blood pressure BGY represents the average of all measured blood pressure value pairs, which is obtained by summing the blood pressure values BPI k (k = 1, 2,..., t) and then dividing by the number of measurements t.

[0098] Calculate the blood pressure stability index BSI according to the blood pressure data, and the formula is as follows:

[0099] ;

[0100] Where, BPI k is the blood pressure value of the kth measurement, k is the serial number corresponding to different measurement times, and its value range is [1, t]; t is the number of measurement times, and its value is a positive integer.

[0101] It should be noted that in this formula: represents the sum of the squares of the differences between the blood pressure value BPI of each measurement k and the average blood pressure BGY. This summation term reflects the total deviation degree between each measured blood pressure value and the average blood pressure value. represents the average deviation degree, and then take the square root of it to obtain a quantity reflecting the blood pressure fluctuation range. The numerator is 1, which plays a fixed numerator role in the whole formula; the blood pressure stability index BSI measures the blood pressure stability by comparing the deviation degree between each measured blood pressure value and the average blood pressure value. When the deviation between each measured blood pressure value and the average value is smaller, the denominator is smaller, and the BSI value is larger, indicating that the blood pressure is more stable; on the contrary, when the blood pressure value fluctuates more, the denominator is larger, and the BSI value is smaller, indicating that the blood pressure stability is worse.

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

[0103] Calculate the blood pressure health index BSQ according to the blood pressure stability index BSI, and the formula is as follows:

[0104] ;

[0105] Where, α is the weight coefficient of the blood pressure stability index BSI, which is determined according to the influence degree of the blood pressure stability index BSI on the blood pressure health index BSQ, and its value range is 0~1.

[0106] It should be noted that in this formula: the first "1" is a constant term, which plays a benchmark role in the whole calculation process. By taking the power of the natural exponential e after performing a weighted operation on BSI, and adding 1 to the value of the exponent part for the entire denominator, a value greater than 1 is obtained for fraction calculation; overall, the value range of BSQ is between 0 and 1. When the value of BSI makes the fraction term close to 0, BSQ is close to 1, indicating better blood pressure health; when the fraction term is close to 1, BSQ is close to 0, indicating poorer blood pressure health.

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

[0108] Sleep data includes 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.

[0109] It should be noted that the total duration of deep sleep DET throughout the night represents the duration of entering deep sleep throughout the night, which is measured by a smart bracelet; the total sleep duration SIE throughout the night represents the sleep duration from going to bed at night to getting up in the morning, which is measured by a smart bracelet for the duration of the entire period from the user falling asleep to waking up; the number of sleep interruptions INM represents the number of times waking up throughout the night. By detecting the body movements of the user during sleep with a smart bracelet, it is determined whether the user has sleep interruptions such as brief awakenings, and the count is obtained.

[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, β 1 is 's weight coefficient, which is determined according to 's influence degree on the sleep recovery effect index SRE, and its value ranges from 0.2 to 0.5; β 2 is 's weight coefficient, which is determined according to 's influence degree on the sleep recovery effect index SRE, and its value ranges from 0.5 to 0.8; and β 1 +β 2 = 1.

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

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

[0115] It should be noted that the duration CYI of the sleep cycle x represents the duration of the x-th sleep cycle, which is obtained by monitoring physiological signals such as the body movement of the user through a smart bracelet, judging different stages of the user's sleep state, and then dividing the sleep cycle and recording the duration of each cycle; the average duration CYE of the normal sleep cycle is obtained by statistical analysis based on the sleep data of a large number of people.

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

[0117] ;

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

[0119] It should be noted that in this formula: the numerator is the sum of the squares of the differences between the duration of each sleep cycle and the average duration of the normal sleep cycle, which reflects the total deviation degree of the duration of each sleep cycle from the average duration of the normal sleep cycle. The denominator f plays a role in normalization, enabling the index to 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 discrete degree of the sleep cycle duration relative to the average duration of the 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 as follows:

[0121] The sleep health index SXZ is calculated according to the sleep recovery effect index SRE and the sleep rhythm disorder index SDQ, and the formula is as follows:

[0122] ;

[0123] Among them, δ 1 is the weight coefficient of the sleep recovery effect index SRE, determined according to the influence degree of the sleep recovery effect index SRE on the sleep health index SXZ, and the value range is 0.1 - 0.3; δ 2 is the weight coefficient of the sleep rhythm disorder index SDQ, determined according to the influence degree of the sleep rhythm disorder index SDQ on the sleep health index SXZ, and the value range is 0.7 - 0.9; and δ 1 +δ 2 = 1.

[0124] It should be noted that in this formula: reflects the influence of the sleep recovery effect index on the sleep health index, and multiplying by the corresponding weight coefficient adjusts the contribution of the sleep recovery effect index to the sleep health index. reflects the influence of the sleep rhythm disorder index on the sleep health index, and multiplying by the corresponding weight coefficient adjusts the contribution of the sleep rhythm disorder index to the sleep health index. The sum of the two is square-rooted to obtain the sleep health index SXZ. Among them, taking the square root mainly plays a role in adjusting the data range, making it more in line with the actual meaning and facilitating comparison; calculating the sleep health index 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 better sleep health; on the contrary, when SRE is lower and SDQ is higher, the value of the sleep health index SXZ is lower, indicating poorer sleep health.

[0125] Specifically, the methods for calculating the blood oxygen stability index HSI and the blood oxygen reserve capacity index RAI are as follows:

[0126] The blood oxygen data includes the blood oxygen saturation value SPL g , the standard blood oxygen saturation value SDP, the blood oxygen perfusion value PIK g and the standard blood oxygen perfusion value PKM.

[0127] It should be noted that the blood oxygen saturation value SPL g under the resting state represents the blood oxygen saturation value measured for the gth time, obtained by measuring the user multiple times with a smart bracelet. For example, each measurement obtains a blood oxygen saturation value, and these values are numbered as SPL 1 , SPL 2 ,..., SPL z in the measurement order; the standard blood oxygen saturation value SDP represents the blood oxygen saturation value as a reference, determined through normal blood oxygen saturation data based on medical research; the blood oxygen perfusion value PIK gDenote the blood oxygen perfusion value of the g-th measurement, which is obtained by measuring the user multiple times with a smart bracelet; the blood oxygen perfusion standard value PKM represents a reference value for comparison, 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 , the blood oxygen saturation standard value SDP, the blood oxygen perfusion value PIK g and the blood oxygen perfusion standard value PKM, calculate the blood oxygen stability index HSI. The formula is as follows:

[0129] ;

[0130] Among them, SPL g is the blood oxygen saturation value of the g-th measurement, PIK g is the blood oxygen perfusion value of the g-th measurement, g is the serial number represented by different measurement times, and the value range is [1, z]; z is the number of measurements, and the value is a positive integer.

[0131] It should be noted that in this formula: the numerator is to sum the products of the differences between the blood oxygen perfusion value and the blood oxygen perfusion standard value and the differences between the blood oxygen saturation value and the blood oxygen saturation standard value for each measurement, which reflects the comprehensive deviation of the blood oxygen perfusion value and the blood oxygen saturation value relative to their respective standard values. The denominator is to sum the squares of the differences between the blood oxygen perfusion value and the blood oxygen perfusion standard value for each measurement, which reflects the total deviation degree of the blood oxygen perfusion value relative to the standard value, is to sum the squares of the differences between the blood oxygen saturation value and the blood oxygen saturation standard value for each measurement, which reflects the total deviation degree of the blood oxygen saturation value relative to the standard value. The square root of the product of the two is taken to obtain the denominator, and the numerator is divided by the denominator to obtain the blood oxygen stability index HSI; comprehensively considering the deviation of the blood oxygen perfusion value and the blood oxygen saturation value relative to their respective standard values to measure the stability of blood oxygen. When the value of the numerator is larger, that is, the deviation of the blood oxygen perfusion value and the blood oxygen saturation value relative to the standard value is larger, the value of HSI is smaller, indicating that the blood oxygen stability is worse; on the contrary, when the value of the numerator is smaller, the value of HSI is larger, indicating that the blood oxygen stability is better.

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

[0133] It should be noted that the maximum value of blood oxygen saturation SPM during exercise represents the maximum value of blood oxygen saturation that appears during exercise and is obtained by monitoring with a smart bracelet when the user is exercising; the average value of blood oxygen saturation SPR at rest represents the average value of blood oxygen saturation when the user is in a quiet rest state such as sitting still or sleeping, and 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 during exercise represents the average value of blood oxygen perfusion during the user's exercise, and 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 at rest represents the average value of blood oxygen perfusion at rest of the user, and 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 comprehensively measuring and calculating the blood oxygen saturation in the exercise and rest states, and is obtained by measuring the blood oxygen saturation values in the exercise and rest states multiple times and calculating their average value.

[0134] The blood oxygen reserve capacity index RAI is calculated based on the maximum value of blood oxygen saturation SPM during exercise, the average value of blood oxygen saturation SPR at rest, the average value of blood oxygen perfusion PLU during exercise, the average value of blood oxygen perfusion PKJ at rest, 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 represents the difference between the maximum value of blood oxygen saturation during exercise and the average value of blood oxygen saturation at rest. The second part represents the difference between the average value of blood oxygen perfusion during exercise and the average value of blood oxygen perfusion at rest. The overall numerator reflects the comprehensive change of blood oxygen saturation and blood oxygen perfusion values in different states; the denominator reflects the product of the blood oxygen saturation in the comprehensive state and the average value of blood oxygen perfusion at rest. Dividing the numerator by the denominator and then taking the square root gives the blood oxygen reserve capacity index RAI, which reflects the comprehensive situation of the body's blood oxygen reserve and regulation ability in different states.

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

[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 product of the two comprehensively considers the stability and reserve capacity of blood oxygen, reflects the degree of difference between the blood oxygen stability index and the blood oxygen reserve capacity index, reflects the degree of consistency between the blood oxygen stability index HSI and the blood oxygen reserve capacity index RAI. The square root in the formula is used to make the value of NJH within a more reasonable range, facilitating the quantification and comparison of blood oxygen energy efficiency. By comprehensively considering the stability and reserve capacity of blood oxygen and their mutual relationship, the blood oxygen energy efficiency of the human body is measured.

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

[0142] Calculate the blood oxygen health index NHG 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, γ 1 is the weight coefficient of the blood oxygen stability index HSI, determined according to the influence degree of the blood oxygen stability index HSI on the blood oxygen health index NHG, with a value range of 0.1 - 0.3; γ 2 is the weight coefficient of the blood oxygen reserve capacity index RAI, determined according to the influence degree of the blood oxygen reserve capacity index RAI on the blood oxygen health index NHG, with a value range of 0.3 - 0.4; γ 3 is the weight coefficient of the blood oxygen energy efficiency index NJH, determined according to the influence degree of the blood oxygen energy efficiency index NJH on the blood oxygen health index NHG, with a value range of 0.4 - 0.5; and γ 1 +γ 2 +γ 3 = 1.

[0145] It should be noted that in this formula: comprehensively consider the blood oxygen stability index, the blood oxygen reserve capacity index, and the blood oxygen energy efficiency index multiplied by the corresponding weight coefficients to calculate the blood oxygen health index. When the value of the blood oxygen health index is higher, it indicates better blood oxygen health status; conversely, when the value of the blood oxygen health index is lower, it indicates worse blood oxygen health status.
