Description
Technical Field

Background
The common body temperature measuring methods include contact temperature measurement and non-contact temperature measurement. The traditional contact type temperature measurement technology generally adopts a mercury thermometer or an electronic thermometer, and is placed in the armpit, the oral cavity and other places for measuring the body temperature. The non-contact temperature measurement generally adopts an infrared forehead temperature gun or an infrared thermal imaging technology, measures forehead temperature in a non-contact mode, and then converts the forehead temperature into body temperature according to an empirical formula.
In general, contact thermometry measures the axillary temperature to be lower than the body's core temperature, approximately 36.7 on average for normal persons, the rectal temperature to be closest to the core temperature of 37.4 degrees, and the oral cavity to be approximately 37.1 degrees. By the contact temperature measurement of the plurality of places, the real temperature can be obtained without compensation. As the body temperature of an individual is deviated, the clinical axillary temperature is generally higher than 37.3 ℃ to diagnose fever. The precision and the reliability of contact temperature measurement are higher, when the operation is good, the influence of environment, individuals and the like is not easy to receive, the commonly used contact thermometer can generally meet the temperature measurement deviation of 0.1 degree, and the contact thermometer has the advantages of high temperature measurement precision, good reliability and low price. However, the conventional contact temperature measurement also has the disadvantages, such as slow temperature measurement, and the like, and the use scenes are limited due to the unchangeable parts such as the need of disinfection when different individuals are used.
Non-contact temperature measurement generally comprises an infrared forehead temperature gun suitable for short distance and single person and a thermal imaging temperature measurement system suitable for long distance and multiple persons. The infrared forehead temperature gun calculates the surface temperature of the forehead by acquiring the infrared energy radiated by the forehead of a person. Usually, the measurement distance is 1-10cm, and because the forehead temperature is measured and has a certain deviation from the body core temperature, the forehead temperature is generally converted into the body internal temperature according to empirical data, and the precision is also affected at the moment. A thermal imaging temperature measurement system generally adopts an infrared thermal imaging array sensor and can measure the temperature of a plurality of people within a certain range. The method comprises the steps of obtaining infrared energy radiated by a plurality of persons, generally selecting a forehead area of the person, calculating the temperature, and converting the temperature into the internal temperature of a body according to the temperature of the forehead. Because the thermal imaging technology is used for measuring in a long distance, the temperature measurement technology is generally more easily influenced by the environment, the temperature measurement precision is generally 2 degrees, and the precision of 0.5 degree can be achieved after the temperature range is accurately adjusted.
Through the analysis, the contact type temperature measurement is inconvenient to use and long in temperature measurement time in the current temperature measurement scheme, the non-contact type temperature measurement is low in precision although the temperature measurement is rapid, the existing temperature measurement is generally single measurement, the personal real-time measurement cannot be followed, and the requirement for real-time temperature measurement cannot be met. Particularly, for sick individuals and in the prevention of infectious diseases, the system is expected to carry out real-time body temperature test on the individuals generally, and early warning is carried out at the first time when abnormal body temperature occurs, so that the individuals and groups can be treated more timely, and risks are reduced.

Detailed Description
Various wearable real-time body temperature measurement solutions appear at present, and the wearable real-time body temperature measurement solutions mainly comprise an electronic temperature measurement patch, an electronic temperature measurement band and several forms of temperature measurement bracelets.
Electronic temperature measurement pastes can paste personnel armpit or chest usually, adopts stickness material to adhere to human surface, obtains human body surface temperature through contact thermistor, then transmits APP on the cell-phone through wireless mode with the data of gathering. Because the electronic temperature measuring paste is generally attached to the key position and covered by the clothes, a more accurate temperature measuring result can be obtained. But is inconvenient in that the general working life is short and the installation and measurement are inconvenient.
The electronic temperature measuring belt is similar to the electronic temperature measuring paste, but the attachment mode is changed into a belt for fixing, and the belt can be fixed in the forehead, the armpit or the chest, and the surface temperature of the human body can be obtained through the contact resistor. The electronic temperature measuring belt is inconvenient to carry or use in formal occasions due to large volume.
The temperature measuring bracelet is in a bracelet shape, is worn on the wrist of a human body, obtains the surface temperature of the wrist and then obtains the body temperature through a series of conversion. Compared with the former two forms, the temperature measuring bracelet is easy to wear, is beautiful and convenient, is suitable for long-term wearing detection and is easily accepted by personnel. However, the temperature measuring bracelet has the problems that compared with the temperature measuring modes, the temperature at the wrist is greatly influenced by the environment, and the temperature measuring module is difficult to obtain accurate and reliable results in the temperature measuring bracelet to measure the body temperature.
Aiming at the problems of inconvenience, real-time checking and low accuracy of body temperature measurement in the prior art, the temperature measurement bracelet provided by the embodiment of the invention can be worn on the wrist of a user as shown in fig. 1, and comprises a bracelet body 1 and a bracelet band 2, wherein the bracelet body comprises: a temperature measuring component 11 and a main board 12; wherein the content of the first and second substances,
the temperature measuring component 11 is used for measuring the skin temperature of the wrist and the ambient temperature around the wrist;
if only the temperature at the wrist is measured, different contraction rates of skin blood vessels can be caused due to the fact that the temperature of the trunk at the far end of the human body is at different ring temperatures, so that the temperature of the wrist cannot directly correspond to the body temperature. Therefore, only the correction is carried out according to the wrist temperature, or the local weather temperature is adopted for compensation, the ambient temperature around the wrist is ignored, and the ambient temperature around the wrist is the main reason for influencing the skin vasoconstriction.
The temperature of the surrounding environment of the wrist is usually affected by the temperature of the local environment, the wearing mode of the individual and the wearing mode of the bracelet, therefore, in the step, the temperature of the skin of the wrist and the temperature of the surrounding environment of the wrist are measured simultaneously by the temperature measuring component, and the body temperature is comprehensively determined by the two temperatures.
The main board 12 is configured to combine the wrist skin temperature and the wrist ambient temperature according to a preset temperature algorithm to obtain a final body temperature.
Alternatively, referring to the cross-sectional view of fig. 2, the thermometric assembly 11, comprises: a first temperature measuring resistor 111 and a second temperature measuring resistor 112; wherein the content of the first and second substances,
the first temperature measuring resistor 111 is located on the outer surface of the bracelet body and used for measuring the ambient temperature around the wrist when the temperature measuring bracelet is in a wearing state;
the second temperature measuring resistor 112 is located on the inner surface of the bracelet body, and when the temperature measuring bracelet is in a wearing state, the temperature measuring resistor is tightly attached to the wrist and used for measuring the skin temperature of the wrist.
The temperature measuring resistor is characterized in that the resistance value of the resistor changes when the temperature of the resistor is different, so that the temperature of the resistor can be calculated reversely according to the change of the resistance value of the resistor.
Optionally, the temperature measuring assembly further includes: a first metal sheet 113 and a second metal sheet 114; wherein the content of the first and second substances,
the first metal sheet 113 is exposed on the outer surface of the bracelet body, covers the upper surface of the first temperature measuring resistor 111 through heat conducting silica gel, and is used for conducting environmental heat to the first temperature measuring resistor 111;
the second metal sheet 114 is exposed on the inner surface of the bracelet body, and covers the upper surface of the second temperature measuring resistor 112 through heat-conducting silica gel, so that the skin heat is conducted to the second temperature measuring resistor 112.
Here, the metal sheet can provide a large contact surface, while also providing low thermal resistance with the surface to be measured and maintaining low thermal resistance with the temperature measuring resistor. This is because the temperature measuring resistor is usually small in volume, so that the contact area with various surfaces is small, the thermal resistance is large, the test is slow, and the contact surface is not easy to control. After the temperature measuring resistor and a metal sheet are bonded through the heat-conducting silica gel, a better temperature sampling surface can be provided, the resistance of the temperature measuring resistor on the measured surface is reduced, and a better temperature measuring effect is obtained.
Optionally, the temperature measuring assembly further includes a thermal resistance material 10, and the main board 12 is located between the first temperature measuring resistor 111 and the second temperature measuring resistor 112, and is separated from the first temperature measuring resistor 111 and the second temperature measuring resistor 112 by the thermal resistance material 10.
Here, the heat blocking material between the temperature measuring resistor and the main board 12 is mainly used for reducing the influence of heat generated by the main board on the temperature measuring resistor when the bracelet body works, and reducing the calculation difficulty. The purposes of high internal thermal resistance and low thermal resistance of the temperature measuring resistor and the measured object can be realized through the heat-resistant material and the metal sheet, and a better temperature measuring effect is obtained.
The main board 12 is specifically configured to:
acquiring a first correction coefficient and a second correction coefficient; the first correction coefficient and the second correction coefficient are obtained by acquiring the wrist temperature and the body temperature of a healthy person at a first standard environment temperature and fitting data;
obtaining the final body temperature according to the formula T-T0 + (T-T1). times.a + b; wherein T is the body temperature, T0 is the wrist skin temperature, T1 is the ambient temperature around the wrist, T is the first standard ambient temperature, a is the first correction coefficient, b is the second correction coefficient. For example, here the first standard ambient temperature t may be chosen to be 25 degrees celsius.
Here, it should be understood that the number of the obtained correction coefficients may be set as required by the temperature measurement accuracy requirement, for example, three correction coefficients may also be used, and when three correction coefficients a, b, and c are used, the final body temperature may be obtained by the formula T0+ (T-T1) ^2 a + (T-T1) b + c, where ^2 represents the square; t is body temperature, T0 is wrist skin temperature, T1 is wrist surrounding environment temperature, T is first standard environment temperature, and a, b and c are three correction coefficients; therefore, by analogy, when four correction coefficients are used, the formula is T-T0 + (T-T1) ^3 × a + (T-T1) ^2 × b + (T-T1) × c + d … …, so that the more correction coefficients are, the more accurate the finally obtained body temperature is, and in actual use, the two correction coefficients can meet most temperature measurement requirements.
Further, the main board 12 may further include various key chips, such as a main control chip, a temperature measurement amplifying circuit, a networking module, a power supply module, and the like, which are not shown in fig. 2, and provide calculation and control functions of a related algorithm, and serve as a main mounting structure body to fix various devices.
The motherboard may also include a networking module (not shown in FIG. 2) through which relevant information can be obtained from a network or other platform. The temperature measurement amplifying circuit amplifies the change of the thermistor, so that more accurate resistance measurement is obtained. In the actual scale deployment process, general temperature measurement bracelet can obtain networking data, through connecting methods such as mobile operator or bluetooth/wiFi, can obtain more accurate temperature measurement result according to the regional or individual correction parameter that the networking was issued, can avoid the deviation that individual difference brought, makes whole scheme adaptability stronger.
Further, referring to fig. 2, the temperature measuring bracelet may further include a battery 13 and a charging interface 14, which are used for providing necessary power supply and meeting the use requirement of the bracelet.
Furthermore, the temperature measuring bracelet can also comprise a screen key 15 which is mainly used for providing an exchange result for a user, and is used for the user to obtain a body temperature measuring result and perform corresponding interaction.
