[0036] The read-only memory 34 and the FLASH memory 35 can not only store the real-time data of 24-hour continuous measurement, but also store the calibration data sent to the local area by the remote terminal device. The read-only memory 34 and the FLASH memory 35 can be built-in to the main control chip or can be a separate storage chip.

[0037] In order to further optimize the above technical solution, the inertial sensor 21 , the first temperature sensor 22 and the second temperature sensor 23 are electrically connected to the main processor 31 via the data interface 37 .

[0038] In order to further optimize the above technical solution, the photoelectric sensor 24 and the electrocardiogram sensor 25 are electrically connected to the main processor 31 through the first analog front end 32, and the sweat sensor 26 is electrically connected to the main processor 31 through the second analog front end 33.

[0039] Combined with Figure 4 , Attachment Figure 6 and attached Figure 9, To further optimize the above technical solution, an electrocardiogram sensor hole 12 and a second temperature sensor hole 13 are provided on the outer side surface of the ring housing 1; the electrocardiogram sensor 25, the second temperature sensor 23, the first analog front end 32 and the second analog front end 33 are installed on the first circuit board 14 located inside the ring housing 1; the first electrocardiogram acquisition electrode 251 of the electrocardiogram sensor 25 extends out of the ring housing 1 through the electrocardiogram sensor hole 12; a second temperature conduction metal 15 is provided on the second temperature sensor hole 13, and a high thermal conductivity material is filled between the second temperature sensor 23 and the second temperature conduction metal 15; a metal contact 16 is also welded on the first circuit board 14, the metal contact 16 extends out of the ring housing 1, and the metal contact 16 and the second temperature conduction metal 15 are respectively electrically connected to the power supply module 4 and serve as charging electrodes to be able to charge the power supply module 4.

[0040] Combined with the attached Figure 5 , the attached Figure 6 and the attached Figure 8 , To further optimize the above technical solution, a photoelectric sensor hole 17 and a first temperature sensor hole 18 are provided on the inner side surface of the ring housing 1; the inertial sensor 21, the photoelectric sensor 24 and the first temperature sensor 22 are installed on the second circuit board 19 located inside the ring housing 1; a first temperature conduction metal 110 is provided on the first temperature sensor hole 18, and a high thermal conductivity material is filled between the first temperature sensor 22 and the first temperature conduction metal 110; the photoelectric sensor 24 includes a photoelectric emission LED 241 and a photoelectric reception PD 242, and a light-shielding member 243 is provided between the photoelectric emission LED 241 and the photoelectric reception PD 242; a biocompatible material cap 112 is covered on the photoelectric emission LED 241 and the photoelectric reception PD 242, and the photoelectric emission LED 241 and the photoelectric reception PD 242 extend out of the ring housing 1 through the photoelectric sensor hole 17; a plurality of wiring copper posts 111 are also provided on the second circuit board 19, and the inertial sensor 21, the photoelectric sensor 24 and the first temperature sensor 22 are electrically connected to the main processor 31 through the wiring copper posts 111, and good waterproof and anti-corrosion functions are achieved through the process of injection molding or potting.

[0041] The main processor 31 is connected through the two surface electrode interfaces of the first analog front end 32 and the electrocardiogram sensor 25. One of the surface electrode interfaces is connected to the first electrocardiogram acquisition electrode 251, and the other surface electrode interface is connected to the first temperature conduction metal 110. The first temperature conduction metal 110 serves as the second electrocardiogram acquisition electrode;

[0042] When detecting an electrocardiogram signal, the fingers of the person to be detected are put together or another finger touches the first electrocardiogram acquisition electrode 251. The first electrocardiogram acquisition electrode 251 can be in contact with the surface of the adjacent finger. Since the second electrocardiogram acquisition electrode, i.e., the first temperature conduction metal 110, is arranged inside the ring housing 1, it can be in contact with the finger pulp of the finger wearing the temperature detection ring, thereby realizing the detection of the electrocardiogram signal.

[0043] To further optimize the above technical solution, the main processor 31 is electrically connected to the photoelectric sensor 24 through the first analog front end 32; furthermore, an internal photoplethysmography module is arranged on the inner side surface of the ring housing 1;

[0044] When the temperature detection ring is worn, the internal photoplethysmography module on the ring is in contact with the finger. The internal photoplethysmography module is electrically connected to the first analog front end 32, and the first analog front end 32 processes the signals from the internal photoplethysmography module; the internal photoplethysmography module includes a photodiode protruding from the inner side surface of the ring housing 1 and at least one light-emitting diode array centrosymmetric about the center of the photodiode. An elastic device is arranged at the bottom of the photodiode or on the inner side surface of the ring housing 1. When the ring is worn, the elastic device is pressed so that the first temperature sensor 22, the photodiode and at least one light-emitting diode array are in close contact with the finger.

[0045] The real-time heart rate value can reflect a person's current cardiac activity ability, and further measure the health status of the human body from the side. In hospitals, electrocardiograms are mostly used to measure heart rate, which is inconvenient to measure during daily activities and exercise. The PPG (photoplethysmographic) pulse wave signal is based on an ILED light source and a detector, measures the attenuated light after being reflected and absorbed by human blood vessels and tissues, depicts the pulsation state of blood vessels and measures the pulse wave, thereby measuring parameters such as heart rate and blood oxygen.

[0046] When light passes through skin tissue and then is reflected to the photosensitive sensor, the light has a certain attenuation. The absorption of light by tissues such as muscle, bone, vein and other connective tissues is basically unchanged (provided that there is no large-scale movement of the measurement site), but blood is different. Due to the blood flow in the artery, the absorption of light naturally also changes. When we convert light into an electrical signal, it is precisely because the absorption of light by the artery changes while the absorption of light by other tissues is basically unchanged that the obtained signal can be divided into a DC signal and an AC signal. Extracting the AC signal can reflect the characteristics of blood flow. We call this technology photoplethysmography PPG.

[0047] To further optimize the above technical solution, the high thermal conductivity material is thermal conductive silica gel or thermal conductive silicone grease.

[0048] To further optimize the above technical solution, the biocompatible material cap 112 is in the shape of a water droplet and made of polydimethylsiloxane or ultraviolet glue.

[0049] Combined with the attached Figure 7 , to further optimize the above technical solution, the first temperature sensor 22 and the second temperature sensor 23 have the same structure, both are in the shape of a cuboid, and include a temperature sensing element 7 and a cuboid-shaped temperature sensor housing 8; the temperature sensing element 7 is located inside the temperature sensor housing 8, and thermal conductive silica gel or thermal conductive silicone grease is filled between the temperature sensing element 7 and the temperature sensor housing 8; the temperature sensor housing 8 is made of a good heat conductor, such as metal copper; one of the sides of the temperature sensor housing 8 that contacts the finger is used as the detection surface, and the other five planes are covered with a poor heat conductor with a thickness of not less than 1 mm, and the poor heat conductor is selected as ultraviolet glue.

[0050] To further optimize the above technical solution, the sweat sensor 26 is arranged on the inner side surface of the ring housing 1, on one side of the photoelectric sensor hole 17, and is in contact with the human skin to detect the sweating condition of the wearing part.

[0051] To further optimize the above technical solution, the main control and data processing module 3 is electrically connected to a wireless module. The wireless module includes a GSM module, a Bluetooth module, and a WIFI module. The GSM module uses base station positioning to transmit the positioning information to the remote server through GPRS; the parameters measured by the sensor module 2 are sent to the terminal device through the Bluetooth module or the WIFI module. The terminal device includes a mobile phone and a tablet computer; after receiving the position, temperature, blood oxygen, electrocardiogram, sweat, and acceleration parameters sent by the wireless module, the terminal device can perform data storage, analysis, and management.

[0052] To further optimize the above technical solution, the main processor 31 can analyze and process the temperature, acceleration, and heart rate parameters detected by the sensor module 2, and issue commands to control the smart terminal through the wireless module. The smart terminal includes an air conditioner and a fan; the control command is a temperature control signal.

[0053] Combined with the attached Figure 2 and the attached Figure 3 , a detection method for a temperature detection ring includes the following two modes:

[0054] Mode 1: The temperature detection ring is worn normally at the root of the finger. The first temperature sensor 22 measures the temperature at the root of the finger, and the second temperature sensor 23 measures the ambient temperature of the finger. At this time, for the calculation of the human body temperature, the measured values of the first temperature sensor 22 and the second temperature sensor 23, as well as the heart rate value measured by the electrocardiogram sensor 25, the sweat information measured by the sweat sensor 26, and the acceleration information collected by the inertial sensor 21, are substituted into the multiple regression equation of Mode 1 for calculation and monitoring;

[0055] Mode 2: The temperature detection ring is worn normally at the root of the finger. Move the hand so that the second temperature sensor 23 of the temperature detection ring directly contacts the forehead, palm or armpit. At this time, for the calculation of the human body temperature, the second temperature sensor 23, as well as the heart rate value measured by the electrocardiogram sensor 25 and the acceleration information collected by the inertial sensor 21, are substituted into the multiple regression equation of Mode 2 for calculation and monitoring.

[0056] Preferably, in the above detection method of a temperature detection ring, in Mode 2, the measured temperature and the measurement time are stored in the FLASH memory 35. The multiple regression equation of Mode 1 can perform coefficient update self-learning according to the historical temperature values measured in Mode 2 stored in the FLASH memory 35.

[0057] The expression of the multiple linear regression model is shown in Equation (1). Each regression coefficient and random error term in Equation (1) are obtained by performing multiple linear regression analysis on the data obtained by the sensor module 2 and the temperature data measured by the ear temperature by the multiple linear regression model; the multiple linear regression model obtains the continuous body temperature by using Equation (1) according to the input multiple physiological parameters.

[0058] Y = a 0 + a 1 X 1 + a 2 X 2 +…+ a k X k + b (1)

[0059] Among them, Y represents the predicted temperature value, X1, X2...XK respectively represent different physiological parameters, a0 is the constant term, a1, a2...ak respectively represent the regression coefficients, and b represents the random error term.

[0060] In Mode 1, X1 represents the temperature T1 measured by the first temperature sensor 22, X2 represents the temperature T2 measured by the second temperature sensor 23, X3 represents the heart rate, and X4 represents the skin conductance. At this time, the multiple regression equation of Mode 1 is obtained.

[0061] In Mode 2, X1 represents the temperature T2 measured by the second temperature sensor 23, X2 represents the heart rate, and X3 represents the skin conductance. At this time, the multiple regression equation of Mode 2 is obtained.

[0062] In the above temperature measurement method, the temperature measured in Mode 2 and the measurement time are stored in the FLASH memory 35. The multiple regression equation of Mode 1 can perform coefficient update self-learning based on the historical temperature values measured in Mode 2 stored in the FLASH memory 35. During the update process, under the premise of the minimum sum of squared errors, the least squares method is used to solve for the parameters. Specifically as follows:

[0063] Let X i =(x 1 , x 2 , …, x i )′, a=(a 1 , a 2 , …, a i )′, e i =(a 0 +b 1 , a 0 +b 2 , …, a 0 +b i )

[0064] Then, Y = X i ′a + e i . During the process of updating the coefficients, the saved data obtained from the multiple regression equation of Mode 2 is updated to the calibration Y sequence, so that a new optimized regression coefficient matrix a can be obtained.

[0065] The temperature detection solution of the embodiment of the present invention can realize the storage of personal long-term historical data and the optimization of the coefficients of the personal temperature monitoring model through historical data. When it is found that the measured temperature exceeds the set threshold, or the trend of the continuously monitored data for 24 hours deviates from the trend of the continuously monitored data for 30 days of the individual by more than a certain threshold, the ring sends a warning message to the remote terminal device.

[0066] Perform feature analysis on the sensor data to determine whether it is a preset action. If so, perform action classification. If not, re-collect multi-dimensional data. The temperature, acceleration, and heart rate parameters detected by the sensor module 2 can be used as control signals for gesture control of the intelligent terminal. According to the classification of gesture actions, external intelligent terminals such as air conditioners and fans can be controlled. For example, when the temperature measured by the first temperature sensor exceeds 37°C, the temperature measured by the second temperature sensor 23 exceeds 32°C, and the heart rate exceeds 90 BPM, by sliding the hand wearing the ring from top to bottom three times, the change feature of the Z axis can be extracted from the acceleration feature, realizing the function of lowering the preset temperature of the air conditioner by 1 degree Celsius or increasing the fan speed. The above functions need to be realized in cooperation with the smart home system.

[0067] The main processor 31 in the main control and data processing module 3 in the embodiments of the present invention may, but is not limited to, be a minimum system module supporting embedded system development produced by Texas Instruments (Ti) or Nordic, such as 2540 of Ti or nRF52832, etc.

(ADI), MAX86150 of Maxim Integrated Products, Inc., etc., or may also be analog circuits built with discrete resistors, capacitors, and operational amplifiers. The first temperature sensor 22 and the second temperature sensor 23 may be LMT70 of TI, T1001 of Huapu, etc. The GPS chip may be selected as MT2503D.
