[0055] The beneficial effects of the present application are as follows:
[0056] Compared with the prior art, the skin temperature measurement and control method of the wearable smart ring has the beneficial effects that the temperature change signal of the user's skin surface is collected in real time by using the skin temperature sensor integrated in the wearable smart ring, the skin temperature is an important physiological parameter reflecting the health status of the human body, which can provide valuable information about body temperature fluctuations, local inflammatory reactions and metabolism, this step can continuously monitor the body temperature change of the user by collecting the skin temperature change signal in real time, and abnormal conditions such as fever, hypothermia or other health problems are found in time, especially in daily health monitoring management, such real-time data collection can help the user better understand his own health status and quickly respond when health problems occur. At the same time, the real-time temperature change signal of the skin surface is sampled and processed by using the high-precision change circuit in the wearable smart ring, which can capture the tiny temperature change and convert it into high-quality electrical signal, and the signal anti-interference circuit in the wearable smart ring is used for anti-interference processing, which can further enhance the stability and accuracy of the signal, so that it is not affected by external environmental interference, even in complex use environment, the smart ring can still provide stable and reliable temperature data, which means that the wearer can still obtain accurate health monitoring information in various life scenes, for example, during exercise, work or other daily activities, reliable body temperature monitoring data can be continuously provided, thereby ensuring the effectiveness and consistency of the health monitoring system. And the skin surface temperature change signal after anti-interference processing is transmitted to the internal processing unit of the smart ring, which can concentrate the processed and optimized signal to the internal processing unit for further analysis and processing, this step ensures the integrity and accuracy of the signal, and converts it into useful health data, the internal processing unit can analyze these data in depth, such as calculating body temperature trend, detecting abnormal fluctuations, etc., and providing personalized health advice or alarm according to the analysis result, which means that the user can obtain instant and accurate health feedback, thereby helping him better manage his health status. Secondly, the temperature signal fluctuation data is converted by using the internal processing unit to input the real-time temperature change signal of the skin surface, which can convert the transient response change value at the corresponding time point of the real-time temperature change signal of the skin surface into usable temperature signal fluctuation data, the data conversion process simplifies the complex change of transient response into standardized temperature data, the core of this step is to convert the original signal change value obtained by transient response analysis into temperature data consistent with actual measurement, so that the measurement result is more practical and accurate, this conversion can remove or reduce noise and error, so that the measurement data is more reliable, and accurate temperature change measurement results are provided for actual application.The accuracy and reliability of the measurement data can be ensured by acquiring external environmental temperature change data and dynamically calibrating and compensating the real-time temperature change measurement data on the skin surface. Changes in the external environment can interfere with temperature measurements on the skin surface, so this can reduce measurement errors caused by environmental changes and make skin surface temperature measurement data more accurate and consistent. This compensation method can effectively eliminate the influence of environmental factors on measurement results, making the data more accurately reflect the actual temperature state of the skin. Through dynamic calibration and compensation, the reliability and effectiveness of the wearable smart ring can be significantly improved, providing more accurate temperature monitoring and adjustment services for users, thereby improving the measurement accuracy and precision of the wearer's skin surface temperature. Then, by uploading the real-time skin surface temperature calibration data to the microcontroller unit of the wearable smart ring and using the microcontroller unit to mark temperature anomalies in the real-time skin surface temperature calibration data, temperature anomalies can be detected and identified in a timely manner. This step compares the real-time temperature data with the set abnormal calibration line to effectively mark temperature changes that exceed the normal range. This method helps quickly locate abnormal areas and triggers an alarm or takes appropriate measures when an anomaly occurs to prevent potential skin problems or health risks. Through precise anomaly marking, the response speed to temperature changes can be improved, and measures can be taken before the problem becomes serious, thereby improving the safety and reliability of the smart ring temperature monitoring process. By analyzing the temperature control target range of the skin surface monitoring temperature anomaly data, a more accurate temperature control target range can be developed. This step analyzes the abnormal distribution of skin surface monitoring temperature anomaly data to determine the appropriate temperature control range for effective intervention when the skin surface temperature is abnormal. Precise temperature control target range can help develop personalized temperature regulation strategies to ensure that temperature control devices operate within the normal range, thereby improving user comfort and safety. This detailed target range analysis can also optimize the response mechanism of the temperature control device to better adapt to different environments and user needs, thereby improving the overall skin temperature control process experience and effectiveness. Finally, by using the microcontroller unit to analyze the temperature control demand instruction response of the skin surface temperature anomaly temperature control target range, this analysis process involves a detailed interpretation of temperature control demands, including the type, degree, and duration of abnormal temperature. Based on this data, appropriate control strategies and instructions will be developed to guide the operation of the temperature regulation control device. For example, if the skin temperature is too high, the device will start the cooling mechanism, and vice versa. Through this process, the accuracy and effectiveness of temperature regulation operations can be ensured, ensuring that the skin always maintains an ideal temperature control range, thereby improving the comfort and health protection of the wearer.In addition, the skin surface temperature control demand response instruction is responded to the temperature adjustment control device of the wearable smart ring, and the temperature adjustment control device is used to perform temperature anomaly control feedback on the skin surface temperature anomaly temperature control target range. These control devices will adjust their working state according to the corresponding control instruction, such as starting the heating or cooling mechanism, to correct the temperature of the skin surface. During the adjustment process, the temperature adjustment control device will also monitor the temperature change in real time and generate temperature anomaly control feedback response signals. These feedback signals will be transmitted back to the wearable smart ring to ensure the accuracy and immediacy of the control operation. This can achieve active and accurate adjustment of the skin surface temperature, ensure that the temperature always remains within the predetermined comfortable range, and improve the experience and health safety of the wearer. The control strategy can also be continuously adjusted and optimized to ensure stable and reliable long-term temperature control effect. BRIEF DESCRIPTION OF DRAWINGS

[0069] In the embodiment of the present application, please refer to the step flow diagram of the skin temperature measurement and control method of the wearable smart ring shown in Figure 1. In this example, the skin temperature measurement and control method of the wearable smart ring includes the following steps:
[0070] Step S1: Real-time acquisition of temperature change signals of the user's skin surface by the skin temperature sensor integrated in the wearable smart ring to obtain the real-time temperature change signals of the skin surface; anti-interference sampling processing of the real-time temperature change signals of the skin surface by the high-precision change sampling circuit and the signal anti-interference circuit in the wearable smart ring, and transmission to the internal processing unit of the wearable smart ring to obtain the real-time temperature change input signals of the skin surface.
[0071] In the embodiment of the present application, the skin temperature sensor integrated in the wearable smart ring is used to real-time acquisition of temperature change signals of the user's skin surface to convert the thermal signals of the skin surface into electrical signals, and through accurate calibration and layout, the sensor can be attached to the skin to reduce environmental interference, and the real-time acquisition of temperature change signals is output in the form of stable voltage change, thereby obtaining the real-time temperature change signals of the skin surface. At the same time, the high-precision change circuit integrated in the wearable smart ring is used to sample and process the previously monitored real-time temperature change signals of the skin surface, which includes a low-noise amplifier and a high-resolution analog-to-digital converter. First, the low-noise amplifier amplifies the weak electrical signals from the skin temperature sensor, and then the high-resolution analog-to-digital converter converts the analog signals into digital signals, ensuring that the acquired temperature change signals have high precision and high resolution. The signal anti-interference circuit integrated in the wearable smart ring is used to optimize the previously filtered high-precision temperature change signals to further process the high-precision filtered temperature change signals and enhance the stability of the signals. The circuit design includes shielding measures, grounding techniques and signal conditioning components, and uses differential amplifiers and noise suppression techniques to reduce the influence of external interference on the signals. The purpose of this circuit processing is to ensure that the temperature change signals are not affected by electromagnetic interference and other factors during transmission. The previously filtered real-time temperature change signals of the skin surface are transmitted to the internal processing unit of the wearable smart ring using wireless transmission technology. After the internal processing unit receives these signals, it further decodes and analyzes the signals, thereby presenting the signals to the user or other systems in a readable format, and ensuring the integrity and accuracy of the data during the transmission of the signals from the skin temperature sensor to the content processing unit. Finally, the real-time temperature change input signals of the skin surface are obtained.
[0072] Step S2: converting the skin surface real-time temperature change input signal into temperature signal fluctuation data by the internal processing unit, obtaining external environment temperature change data, and performing temperature dynamic calibration compensation on the skin surface real-time temperature change measurement data based on the external environment temperature change data to obtain skin surface real-time temperature calibration data;
[0073] In the embodiment of the present application, the signal processing module of the internal processing unit uses the fast Fourier transform (FFT) algorithm to perform frequency spectrum mapping conversion on the previously input skin surface real-time temperature change input signal to convert the input skin surface real-time temperature change input signal into frequency spectrum form, which can reveal the frequency components in the temperature change signal and calculate statistical indicators such as standard deviation and root mean square value of the temperature change signal spectrum to evaluate and analyze the fluctuation amplitude of the temperature change signal. At the same time, the sliding window technique is used to sample and record the data at each time sequence point, and the temperature signal fluctuation amplitude at each time sequence point is accurately captured. By using frequency domain analysis methods such as fast Fourier transform (FFT) or wavelet transform, the fluctuation amplitude of the skin surface temperature signal at each time sequence point obtained by previous analysis is statistically analyzed to convert time series data into frequency spectrum data, and the fluctuation amplitude in the frequency spectrum data is analyzed to identify the characteristics of transient response such as temperature peak value, periodic fluctuation, etc. By using statistical analysis tools such as mean, variance, and dynamic time warping (DTW) algorithm, the fluctuation amplitude of the skin surface temperature signal at each time sequence point is analyzed to identify the change pattern, so as to identify the change trend and pattern of the fluctuation amplitude by comparing the fluctuation changes at different time points. By combining the previously analyzed signal fluctuation amplitude change pattern, the fluctuation amplitude transient response characteristics at each time sequence point are dynamically corrected to apply the change pattern to the transient response characteristic data, adjust the offset or noise in the response characteristic data, and use the following calculation formula to quantitatively calculate the transient response change value of the temperature signal transient response characteristic correction data at each time sequence point after dynamic correction, wherein the calculation formula can be: where ΔU i is the fluctuation transient response change value of the skin surface temperature signal at time sequence point t i , t i is the current time sequence point, and t i-1 is the previous time point, s is the integral time variable parameter of the transient response change value quantization calculation, U(s) is the temperature signal transient response characteristic correction data at time point s, δ1 is the influence coefficient of the first-order derivative of the temperature transient response on the transient change value, δ2 is the influence coefficient of the second-order derivative of the temperature transient response on the transient change value, ∈ is the correction coefficient, to quantify the change of the transient response, and the transient response change value at each time point is converted into standardized temperature measurement data according to the time sequence. The conversion process ensures that the temperature change data accurately reflects the actual temperature change of the skin surface, so as to obtain the skin surface real-time temperature change measurement data. Then, the temperature data of the environment around the wearer of the wearable smart ring is collected through a corresponding environmental temperature sensor (such as a high-precision digital thermometer), so as to obtain the external environment temperature change data. The skin surface real-time temperature change measurement data corresponding to the same time sequence dimension is also dynamically calibrated and compensated for temperature by combining the previously collected external environment temperature change data, so as to compare and adjust the environmental temperature change with the skin surface measurement data, adjust the temperature measurement value at each time point, and eliminate the influence of environmental factors on the measurement data. For example, by using the formula: calibrated temperature = real-time temperature + calibration compensation coefficient, each time point is corrected to ensure that the skin surface temperature data at each time point is closer to the true value after compensation, and finally the skin surface real-time temperature calibration data is obtained.
[0074] Step S3: uploading the skin surface real-time temperature calibration data to the microcontroller unit of the wearable smart ring, and using the microcontroller unit to mark the skin surface real-time temperature calibration data for temperature abnormal response to obtain skin surface monitoring temperature abnormal data; analyzing the skin surface monitoring temperature abnormal data for temperature control target range to obtain the skin surface temperature abnormal temperature control target range;
[0075] In the embodiment of the present application, the skin surface real-time temperature calibration data obtained after previous calibration compensation is uploaded to the microcontroller unit of the wearable smart ring by using wireless transmission technology (such as Bluetooth or wireless local area network), and after the microcontroller unit receives the skin surface real-time temperature calibration data, it visualizes the received skin surface real-time temperature calibration data by using the built-in data visualization algorithm, including arranging the temperature calibration data in chronological order and calculating the temperature change amplitude at each time point, thereby drawing the temperature calibration change curve, and using the pre-set temperature anomaly calibration line as the reference standard to mark the temperature anomaly on the previously drawn temperature calibration change curve, wherein the calibration line represents the upper and lower limits of the normal temperature range, for example, if the normal range is 36.5℃ to 37.5℃, the calibration line will be set in the region of these two temperature values, the microcontroller unit compares the real-time temperature curve with these calibration lines, identifies all temperature points that exceed the calibration line range, and marks these over-standard temperature points as temperature anomalies, thereby obtaining skin surface monitoring temperature anomaly data. Then, by analyzing the previously marked skin surface monitoring temperature anomaly data in detail, the specific operation includes classifying and counting all abnormal data points according to the frequency of occurrence and temperature range, drawing an abnormal data distribution graph, and using statistical methods such as standard deviation and coefficient of variation to evaluate the distribution of abnormal data during the analysis process. In addition, the corresponding skin surface monitoring temperature anomaly data is statistically analyzed to determine the temperature control target range by combining the temperature anomaly distribution values obtained from the previous analysis, so as to calculate the actual deviation range of the skin surface temperature using the temperature anomaly distribution values, for example, by combining the pre-set normal temperature range (such as 36.5℃ to 37.5℃), a suitable temperature control target range is determined (if the corresponding abnormal distribution value is 36℃, the temperature control target range is +0.5℃ to +1.5℃; if the corresponding abnormal distribution value is 38℃, the temperature control target range is -1.5℃ to -0.5℃), which takes into account the degree of temperature anomaly to ensure effective adjustment and control of the skin surface temperature in actual application.

[0151] In the embodiment of the present application, the temperature dynamic calibration compensation is performed on the corresponding real-time skin surface temperature data according to the skin surface temperature calibration compensation coefficient at each temperature change time point obtained after the previous temperature calibration compensation. The specific operation includes applying the calibration compensation coefficient to the actual temperature data, adjusting the temperature measurement value at each time point, for example, correcting each measurement point by using the formula: calibrated temperature = real-time temperature + calibration compensation coefficient. This process ensures that the skin surface temperature data at each time point is closer to the true value after compensation, and finally obtains the real-time skin surface temperature calibration data.

[0154] The present application obtains a temperature calibration compensation calculation formula through the use of a specific mathematical model and verification, which is used for temperature calibration compensation calculation of real-time temperature data of the skin surface at the same temperature change time point. The temperature calibration compensation calculation formula can more accurately reflect the actual temperature state of the skin by calibrating the difference between the skin surface temperature and the environmental temperature. The integral term in the formula takes into account the time decay effect of temperature difference, which can dynamically adjust the calibration compensation coefficient, meaning that not only the current temperature difference is considered, but also the influence of historical temperature difference is included, providing more comprehensive compensation. Secondly, the formula can adapt to different temperature change rates and amplitudes, thereby improving the temperature compensation ability under different environmental conditions. By introducing a correction value, the calibration compensation coefficient can be further adjusted to compensate for systematic errors or incomplete calibration factors in the calculation process. Then, the integral part of the formula provides in-depth analysis of the time series data of temperature change, which helps to identify temperature change trends and patterns, thereby better understanding the dynamic changes of skin temperature. By adopting this compensation method that comprehensively considers the time decay effect, the system performance can be optimized, and the temperature measurement errors caused by environmental factors can be reduced. In summary, the formula fully considers the skin surface temperature calibration compensation coefficient δ(t) at the temperature change time point t, the time variable parameter t of the temperature change time point, the integral time variable parameter τ, the real-time skin surface temperature T s (t) at the temperature change time point t, the external environmental temperature T e (t) of the skin surface at the temperature change time point t, the skin surface internal and external temperature difference scaling coefficient α, the time decay velocity τ c , the skin surface internal and external temperature difference influence coefficient β, the correction value η of the skin surface temperature calibration compensation coefficient, and forms a functional relationship according to the mutual relationship between the skin surface temperature calibration compensation coefficient δ(t) at the temperature change time point t and the above parameters:

For example, by combining the preset normal temperature range (for example, 36.5-37.5℃), a proper temperature control target range is determined (if the corresponding abnormality distribution value is 36℃, the temperature control target range is +0.5-1.5℃; if the corresponding abnormality distribution value is 38℃, the temperature control target range is -1.5-0.5℃). The target range takes into account the degree of temperature abnormality, so as to effectively adjust and control the skin surface temperature in actual application, and finally obtain the skin surface temperature abnormality temperature control target range, which will be used to guide the actual temperature adjustment operation, so as to maintain the skin surface temperature in the safe range.

That is, if the skin surface temperature abnormality temperature control target range is +0.5℃ or -0.5℃, the temperature control demand analysis is determined as heating 0.5℃ or cooling 0.5℃. These temperature control demands include the temperature amplitude to be adjusted, the adjustment speed and the response time, etc. Finally, the corresponding skin surface temperature abnormality temperature control demand is obtained.

For example, in the analysis process, the temperature control demand is converted into specific control instructions by considering the accuracy of temperature adjustment, reaction time and system capacity, which include the amplitude, duration of heating or cooling and feedback adjustment mechanism in the adjustment process, and finally the skin surface temperature control demand response instruction is generated, which includes detailed operation steps and execution parameters, and is formatted into a signal format suitable for transmission to the intelligent ring control device.
