All other embodiments obtained by the person of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the protection scope of the present invention.
In one embodiment, as shown in fig. 1, a method for non-contact measurement of body temperature is provided, which comprises the following steps 101-104:
s101, measuring the target body temperature of the target person through a thermometer.
In this embodiment, the thermometer may be used for remote body temperature measurement, which may be measuring the body temperature of a target person at a distance of 1 meter from the target person.
And S102, obtaining the distance between the thermometer and the target person and the value of the current environmental factor.
In this embodiment, a distance sensor is installed on the thermometer to measure the distance between the thermometer and the target person, so as to calculate the distance compensation value, and the temperature is decreased with the distance when measuring the temperature.
In this embodiment, the value of current environmental factor includes ambient temperature and ambient relative humidity, is equipped with temperature and humidity sensor on the clinical thermometer, because the distance of measuring is far away, the ambient temperature and the ambient relative humidity of current environment can influence, and temperature and humidity sensor is used for measuring the ambient temperature and the ambient relative humidity of current environment to be convenient for calculate first temperature compensation value and humidity compensation value.
S103, calculating a temperature compensation coefficient according to the target body temperature, the distance and the value of the current environmental factor.
In this embodiment, the distance compensation value CD ═ 1+ (distance × 0.006) can be calculated according to the following formula, where CD represents the distance compensation value and distance represents the distance measured by the distance sensor.
In this embodiment, the first temperature compensation value CV1 may be calculated as (25-TA) × 0.01 according to the following formula, where CV1 represents the first temperature compensation value, and TA represents the ambient temperature measured by the temperature and humidity sensor in the current environment.
In this embodiment, the humidity compensation value CRh ═ RH × 0.0001 may be calculated according to the following formula, where CRh represents the humidity compensation value, and RH represents the environmental relative humidity measured by the temperature and humidity sensor in the current environment.
In this embodiment, the second temperature value CV2 ═ 0.01 (TO-25/2) ×, where CV2 represents the second temperature compensation value and TO represents the target body temperature measured by the target person, may be calculated according TO the following formula.
In this embodiment, the temperature compensation coefficient is calculated according to the target body temperature, the distance, and the value of the current environmental factor, and the temperature compensation coefficient Csum ═ CD + CV1+ CV2+ CRh may be calculated according to the following formula, where Csum represents the calculated temperature compensation coefficient, CD represents the distance compensation value, CV1 represents the first temperature compensation value, CV2 represents the second temperature compensation value, distance represents the distance between the thermometer and the target person, and CRh represents the humidity compensation value.
In this embodiment, the temperature compensation coefficient may also be expressed as Csum ═ TO-25/2 × (0.01 + (25-TA) × 0.01+1+ (distance × (0.006) + RH × (0.0001), where Csum represents the calculated temperature compensation coefficient, TO represents the target body temperature of the target person, TA represents the ambient temperature, distance represents the distance between the thermometer and the target person, and RH represents the ambient relative humidity.
And S104, calculating to obtain the real body temperature of the target person according to the temperature compensation coefficient and the target body temperature.
In this embodiment, the real body temperature of the target person is calculated according TO the temperature compensation coefficient and the target body temperature, and the real body temperature TB ═ TO × Csum of the target person may be calculated according TO the following formula, where TB represents the calculated real body temperature of the target person, TO represents the target body temperature measured by the target person, and Csum represents the calculated temperature compensation coefficient.
Specifically, as shown in fig. 2, measuring the target body temperature of the target person by the thermometer may include the following steps 201 to 203:
s201, simultaneously collecting a plurality of sample body temperatures of the face of a target person through an infrared sensor;
s202, judging whether the number of the sample body temperatures reaches a preset value or not, if not, re-collecting a plurality of sample body temperatures of the target person until the number of the collected sample body temperatures reaches the preset value;
and S203, if the sample body temperature reaches a preset value, determining a target body temperature according to a preset rule and the plurality of sample body temperatures.
For the step 201, in this embodiment, the simultaneous acquisition is that the user turns on the thermometer once to acquire a plurality of body temperatures simultaneously in a short time. The acquired body temperatures are analyzed to obtain a plurality of sample body temperatures, and then the target body temperature is analyzed from the plurality of sample body temperatures.
For understanding, further, the step of simultaneously acquiring a plurality of sample body temperatures of the face of the target person by the infrared sensor may include the following one or two modes:
as shown in fig. 3, the first method includes the following steps 301 to 304:
s301, simultaneously acquiring a plurality of body temperatures of the same region of the face of a target person through an infrared sensor;
s302, judging whether the body temperatures are in a preset interval or not;
s303, if the body temperature is within a preset interval, determining the body temperature within the preset interval as the sample body temperature;
and S304, if the body temperature is not in the preset interval, processing according to a preset flow.
For the above steps 301 and 302, a body temperature of an area of the human face may be obtained by using an MLX90614 infrared sensor, and whether the body temperature is within a preset interval is determined, if so, the body temperature is determined as a sample body temperature, the collected body temperatures are analyzed one by one, and whether the body temperatures are within the preset interval is continuously determined.
For example, 5 body temperatures of a certain area of the face of the target person are collected simultaneously, whether the 5 body temperatures are within a preset interval is judged, optionally, the preset interval can be set to be 35-40 degrees, the target person generally has low fever, high fever or normal body temperature within the range, and whether the collected 5 body temperatures are within the preset interval is judged one by one.
For the step 303, the body temperature within the preset interval is determined as the sample body temperature, and if the acquired 5 body temperatures are within the preset interval, all the 5 body temperatures can be determined as the sample body temperature.
In step 304, the body temperature that is not within the preset interval is processed according to a preset flow, for example, the body temperature measured at 34 ° can be determined as abnormal body temperature, and the processing can be directly discarded.
It should be noted that the number of samples and the body temperature are only used to describe the embodiment more clearly, and the embodiment does not limit this.
As shown in fig. 4, the second method includes the following steps 305 to 307:
s305, simultaneously collecting a plurality of body temperatures of different areas of the face of a target person;
s306, acquiring the body temperature in a preset interval from the body temperatures in the different areas;
and S307, determining the highest body temperature obtained in the preset interval as the sample body temperature.
For the above step 305, an MLX90621 infrared sensor may be used to obtain a 4 × 16 infrared matrix, that is, 64 body temperatures of different areas of the face of the target person are obtained, 64 individual temperatures are collected for multiple times, and 5 × 64 individual temperature data are obtained when 64 individual temperatures are collected once, for example, 5 times, and the multiple body temperatures are analyzed one by one.
For the step 306, the body temperature in the preset interval is obtained from the body temperatures in the different areas, for example, the MLX90621 infrared sensor can obtain 64 individual temperature data which are read at one time, and obtain a plurality of body temperatures in the preset interval from the 64 individual temperature data. For example, the normal body temperature of a person is set within the interval of 35-40, the body temperature within the interval is obtained from the 64 body temperatures, and other body temperatures which do not meet the interval are discarded.
In step 307, the highest body temperature obtained in the preset section is determined as the sample body temperature for the plurality of body temperatures in the preset section. If the 64 individual temperature ranges meet the 60 body temperatures in the preset range, then the 60 individual temperature ranges with the highest body temperature is judged, and the highest body temperature is determined as the sample body temperature.
It should be noted that the number of samples and the body temperature are only used to describe the embodiment more clearly, and the embodiment does not limit this.
For the step 202, it is determined whether the number of the sample body temperatures reaches a preset value, when the number of the sample body temperatures is smaller than the preset value, that is, the number of the sample body temperatures does not reach the preset value, a plurality of sample body temperatures of the target person are collected again until the number of the collected sample body temperatures reaches the preset value, for example, 5 sample body temperatures are needed, when 5 body temperatures are read at the same time, it is determined whether 5 sample body temperatures are reached, if not 5, the read body temperatures are given up, and the reading of the body temperatures is restarted for 5 times until 5 sample body temperatures are continuously read for 5 times and reached.
It can be understood that in the process of determining the body temperature of the sample, the body temperature does not conform to the preset interval, and the body temperature collected for 5 times is not necessarily all the body temperature of the sample, and if the number of the body temperatures of the sample is less than the number of times of collection, the calculation of the body temperature is abandoned, and the collection is restarted.
It should be noted that the number of samples is only used to describe the embodiment more clearly, and the embodiment does not limit this.
For the step 203, when the number of the sample body temperatures reaches a preset value, the target body temperature is determined according to a preset rule and a plurality of the sample body temperatures, specifically, as shown in fig. 5, the step of determining the target body temperature according to the preset rule and the plurality of the sample body temperatures in the step 203 may include the following steps 401 to 403:
s401, calculating the difference value between every two of the body temperatures of the plurality of samples;
s402, determining the sample body temperatures with the body temperatures closest to the body temperatures in the preset number according to the difference;
and S403, calculating the average value of the sample body temperatures of the preset number to obtain the target body temperature.
As for the step 401, it can be understood that differences are calculated between every two sample body temperatures, if there are 5 sample body temperatures, differences are respectively calculated between every two sample body temperatures of 5 sample body temperatures, and the closest sample body temperatures can be calculated according to the differences.
For the above steps 402 and 403, for example, after obtaining the difference between each two of the plurality of sample body temperatures, if 3 final sample body temperatures are preset, selecting 3 closest sample body temperatures from the 5 sample body temperatures according to the plurality of differences, and averaging the 3 sample body temperatures to obtain the final target body temperature of the target person.
It should be noted that the number of samples and the preset number are only used for describing the embodiment more clearly, and the embodiment does not limit this.
In a preferred embodiment of the invention, through face recognition, multiple times of historical temperatures of target personnel can be recorded and stored for the target personnel, and it can be understood that one thermometer is not only used by one person, but also the temperatures of different target personnel can be respectively recorded and stored through face recognition.
Specifically, in another preferred embodiment of the present invention, the infrared sensor with the model number of MLX90614 is used to simultaneously acquire a plurality of body temperatures of the same area of the face of the target person, and the MLX90614 sensor can measure the temperature of one point of the face of the target person, and then analyze the plurality of simultaneously acquired temperatures. Or a plurality of body temperatures of different areas of the face of the target person are simultaneously acquired through an MLX90621 infrared sensor, the MLX90621 can measure 64-point temperatures of the face of the target person, the 64-point temperatures are a 4 x 16 infrared temperature matrix, and then the temperatures are analyzed.
Specifically, considering that the normal body temperature of each person is different, after the real body temperature of the target person is measured, as shown in fig. 6, the method may further include:
s501, obtaining a plurality of real body temperatures of a target person within a preset time period;
s502, determining a normal body temperature threshold of a target person according to the real body temperatures;
s503, measuring and calculating the current real body temperature of the target person, and comparing the current real body temperature with the normal body temperature threshold value;
s504, when the current real body temperature is lower than the minimum value of the normal body temperature threshold value, judging that the body temperature of the target person is lower;
s505, when the current real body temperature is within the normal body temperature threshold range, judging that the body temperature of the target person is normal;
s506, when the current real body temperature is higher than the maximum value of the normal body temperature threshold value, judging that the body temperature of the target person is higher.
For the above step 501, it is known that the body temperature of each person is different, for example, the body temperature of the pregnant woman is higher, the body temperature of the infant, the juvenile, the adult, and the elderly is different, and the normal body temperature of the female and the male is different. Even if each person has a different body temperature per day, for example, the body temperature of a person may be slightly lower in the morning and slightly higher in the afternoon. In view of the above, it is necessary to measure the normal body temperature threshold of the target person.
In a specific application scenario, the target person may measure the body temperature of the target person irregularly, and after the real body temperature is obtained through each measurement, the body temperature obtained through each measurement is recorded, so that the normal body temperature threshold of the target person can be measured subsequently. When the target person carries out the next body temperature measurement, a plurality of real body temperature data recorded in the previous time within a certain time are read out, and the time can be set by the target person or can be specified by the system.
For the step 502, it can be understood that different faces are obtained according to the face recognition, and the temperatures of different target persons may respectively correspond to the respective faces, so that for different target persons, the temperature measured by the same thermometer by multiple persons has no influence on the history of the target persons, and also has no influence on the calculation of the normal body temperature threshold of the target persons.
For the above step 503, the real body temperature obtained by the current measurement is compared with the normal body temperature threshold, for example, the real body temperature obtained by each measurement is recorded in the database, the target body temperature with the time closest to the current time is read from the database 100 times at each time of starting the thermometer, the average temperature is calculated, assuming that the average temperature of the target person is 36.8 °, the normal body temperature threshold can be determined to be 36.6 ° -37.1 °, the temperature can be floated by 0.3 ° up and down, and the real body temperature obtained by the current measurement is compared with the normal body temperature threshold.
For the above steps 504-506, after the normal body temperature threshold of the target person is obtained through measurement, one of normal body temperature, low body temperature and high body temperature of the target person is determined according to the normal body temperature threshold. For example, when the normal body temperature threshold of the person a obtained by measurement is 37 ° to 37.5 °, and the current measured real body temperature is 36.5 °, the current measured real body temperature is compared with the normal body temperature threshold, so that the body temperature is known to be low, and when the current measured target body temperature is 37.2 °, the current measured real body temperature is compared with the normal body temperature threshold, so that the body temperature is known to be normal, and when the current measured real body temperature is 38 °, the current measured real body temperature is compared with the normal body temperature threshold, so that the body temperature is known to be high.
It should be noted that the above temperature is only used for describing the embodiment more clearly, and the embodiment does not limit this.
In a further preferred embodiment of the present invention, a speaker having a sound producing function, such as a speaker, is mounted on the thermometer, so that the measurement result can be directly reported by voice. For example, the thermometer is started, the body temperature value is directly displayed, the body temperature detection result is broadcasted in a voice mode, the results of normal body temperature, low body temperature or high body temperature and the like are informed to target people, and the use of people with visual disorder is facilitated.
In another preferred embodiment of the invention, the thermometer is provided with a function key, and a target person only needs to press the key to complete a series of operations such as starting up, measuring the body temperature, shutting down and the like, so that the thermometer is convenient for old people to use.
Firstly, measuring the target body temperature of a target person by the thermometer; then, obtaining the distance between the thermometer and the target person and the value of the current environmental factor; secondly, calculating a temperature compensation coefficient according to the distance and the value of the current environmental factor; and finally, calculating to obtain the real body temperature of the target person according to the temperature compensation coefficient and the target body temperature. Therefore, the invention can realize the remote measurement of the real body temperature of the target person by compensating the measured target body temperature, the measured distance and the measured environmental factors.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
In one embodiment, a device for measuring body temperature in a non-contact manner is provided, and the device for measuring body temperature in a non-contact manner corresponds to the method for measuring body temperature in a non-contact manner in the above embodiments.
