Embodiments of the present invention provide a temperature detection method and a terminal device, which can quickly and accurately detect the temperature of an external environment where a user is located and output a temperature value.

The following uses a terminal device as an example to illustrate the temperature detection method provided by the embodiment of the present invention.

The temperature detection method provided by the embodiment of the present invention can be applied to a scene where the user's environment changes suddenly, resulting in a temperature change.

Embodiment one

As shown in Figure 1a, an embodiment of the present invention provides a temperature detection method, which may include the following steps:

101. Acquire reading values of M sensors to obtain M first temperature values.

Wherein, M sensors are arranged inside the terminal device, and different sensors have different distances from the surface of the terminal device, where M is an integer greater than or equal to 3. At any moment, the reading values of the first sensor, the second sensor, ..., the Mth sensor are obtained respectively, so as to obtain M first temperature values.

In the embodiment of the present invention, the terminal device is taken as an example. As shown in FIG. The distances are different. As shown in the figure, only M sensors are set in the space near the surface of the display screen 13 inside the terminal device. There is a certain distance between any two sensors. The distance can be fixed or flexibly set. distance. At any moment, the reading values of the first sensor, the second sensor, .

But in the face of wearable devices, since part of the surface of the wearable device is in contact with the human body and will not be exposed to the air, each sensor set in the wearable device only needs to be connected to a certain area where the display screen of the wearable device is located. The distance between the planes may be different. Take the phone watch as an example, as shown in Figure 1c, M sensors are arranged inside the watch body 14 of the phone watch, from the bottom plate 15 of the watch body to the middle area of the watch case 16 of the watch body, each sensor is connected to the watch body of the watch body The distances of the watch case 16 are different, and there is a certain distance between any two sensors. At any moment, the reading values of the first sensor, the second sensor, .

Optionally, before obtaining the readings of the M sensors, the terminal device can also detect whether it is in the wearing state, and if it is detected that the terminal device is in the wearing state, then perform steps 101-105 according to the sensor settings in Figure 1c. If it is detected that the terminal device is not in the wearing state, according to the sensor setting in Fig. 1b, the temperature is detected only through the sensor close to the surface where the display screen is located, and steps 101-105 are performed.

102. Determine whether there is a direct proportional relationship or an inverse proportional relationship between the M first temperature values and the distances between different sensors and the surface of the terminal device.

In the embodiment of the present invention, by using the M first temperature values and the distances between the M sensors and the surface of the terminal device, the relationship between the temperature value and the distance between the sensors and the surface of the terminal device can be determined. Among the M sensors, each sensor will have a reading value. At this time, the reading value of each sensor and the distance between each sensor and the surface of the terminal device are one-to-one, and then the relationship between the two is determined.

It is understandable that when the user is in a fixed environment for a period of time, there will be no heat flow inside the terminal device. At this time, the reading values of multiple sensors inside the terminal device should be the same. When the user suddenly leaves the fixed environment and enters a When in a new environment, the temperature of the external environment will change, which will cause the reading values of the M sensors to change. It is conceivable that the closer the sensor is to the surface of the terminal device, the closer it is to the external environment, and the faster the temperature change will be; on the contrary, the farther the sensor is from the surface of the terminal device, the farther it is from the external environment, the temperature change will be faster The speed will also be slower. Therefore, it can be shown that no matter whether the temperature of the external environment increases or decreases, the reading value of the sensor closer to the surface of the terminal device will change faster, that is, the value of the change will be larger.

103. If there is a direct proportional relationship or an inverse proportional relationship, according to the M first temperature values, a temperature parabolic curve is obtained by fitting the least squares method.

If there is a direct proportional relationship or an inverse proportional relationship between the M first temperature values and the distances between different sensors and the surface of the terminal device, then it can be determined that the user has left the fixed environment and entered a new environment with a different temperature. At this time, a temperature parabolic curve can be obtained by performing curve fitting according to the M temperature values at the same time through the least squares algorithm. The abscissa of the temperature parabolic curve is the distance between the sensor and the surface of the terminal equipment, and the ordinate of the temperature parabolic curve is the temperature value. Among them, curve fitting is a data processing method that uses a continuous curve to approximately describe a curve composed of multiple discrete points that represents the functional relationship between each point.

In the embodiment of the present invention, by acquiring the reading values of M sensors, and correlating these reading values with the distance between the sensor and the surface of the terminal device, a plurality of data points p _i ( _xi , y _i ) are first obtained, where i=1 . To the least squares method, the least squares method can determine the temperature parabolic curve according to the principle of the smallest sum of squared deviations and fitting polynomials.

First, the fitting polynomial can be assumed to be the following formula (1):

y＝a ₀ +a ₁ x+…+a _k x ^k (1)

The temperature parabolic curve obtained by fitting needs to have the smallest difference with the temperature value of each data point, so it is necessary to obtain the sum of the squares of the difference between the ordinate value of each data point and this curve, as shown in the following formula (2):

Then calculate the partial derivative of the sum of squares of the differences, and the following formulas (3)(4)(5) can be obtained:

Then the formulas (3)(4)(5) are simplified respectively, and the following formulas (6)(7)(8) can be obtained:

Then formula (6)(7)(8) is expressed in matrix form, and formula (9) can be obtained:

Simplify each matrix in formula (9), and formula (10) can be obtained:

That is, X*A=Y, so A=(X′*X-1*X′*Y), so that the coefficient matrix A can be obtained, that is, the values of a ₀ , a ₁ ,…, a _k , which are brought into the fitting The temperature parabola can be obtained from polynomial (1).

104. Determine the apex temperature value of the temperature parabolic curve as the ambient temperature value.

The terminal device may use the temperature value corresponding to the apex of the temperature parabolic curve as the ambient temperature value.

Among them, if the user enters from a high-temperature environment to a low-temperature environment, the temperature parabolic curve is a parabola that first decreases and then increases, with the opening upward, as shown in Figure 1d, the lowest point of the temperature parabolic curve can be The temperature value corresponding to the point is determined as the ambient temperature value; if the user enters from a low-temperature environment to a high-temperature environment, then the temperature parabolic curve is a parabola that first increases and then decreases, with the opening downward, as shown in Figure 1e As shown, the temperature value corresponding to the highest point of the temperature parabolic curve can be determined as the ambient temperature value.

105. Output the ambient temperature value.

An embodiment of the present invention provides a temperature detection method. Multiple temperature values are obtained by obtaining the readings of multiple sensors installed inside the terminal device at the same time. If there is a gap between the multiple temperature values and the distance between the sensor and the surface of the terminal device A certain proportional relationship or inverse proportional relationship can indicate that the current ambient temperature of the user has changed to a certain extent. At this time, a temperature parabolic curve can be fitted according to multiple temperature values, and the temperature value corresponding to the apex of the curve can be determined as The ambient temperature value, and finally output the ambient temperature value. This technical solution can quickly obtain an accurate ambient temperature value by acquiring multiple sensor readings at any time after detecting that the current ambient temperature of the user has changed to a certain extent without waiting for the sensor reading to stabilize. , and remind the user of the current ambient temperature.

As an optional implementation, the terminal device can also obtain the readings of M sensors at N times to obtain N*M first temperature values; obtain a temperature parabolic curve according to the M first temperature values at each time, To obtain N temperature parabolic curves; respectively obtain the apex temperature value of each temperature parabolic curve to obtain N apex temperature values; take the average value of the N apex temperature values as the ambient temperature value, and output the ambient temperature value.

In this optional implementation manner, the terminal device may acquire multiple temperature values at multiple times, and then calculate an average value according to the temperature values corresponding to the vertices determined at each time, so as to obtain the ambient temperature value. This solution calculates the average value of multiple temperature values to obtain the final ambient temperature value, which can make the detection of the ambient temperature more accurate and avoid inaccurate environmental temperature values caused by insufficient sensitivity of the sensor.

As an optional implementation, the terminal device can also obtain the user's class schedule information. If it is detected that the user's body temperature has risen at the end of the physical education class and is higher than the normal body temperature range, it can be explained that the user has just finished. Physical education class, at this time, the reading values of M sensors can be obtained to obtain M first temperature values, and a temperature parabolic curve can be obtained according to the M first temperature values, and the temperature value at the apex of the temperature parabolic curve can be determined as the ambient temperature value. At this time, the above-mentioned ambient temperature value is compared with the preset temperature value. If the ambient temperature value is lower than the preset temperature value, a fourth prompt message is output to remind the user that the current ambient temperature is low and there is a risk of catching a cold. Optionally, if the ambient temperature value is lower than the preset temperature value, the terminal device can also control the screen to emit a red light warning to prompt the user.

Exemplarily, the preset temperature value is a pre-stored temperature that the user feels more comfortable (for example, it may be a certain temperature value lower than the normal body temperature of the human body). The season and user information (may include the user's sick leave record, class schedule, etc.) are comprehensively set, and can also be set by the user.

For example: the terminal device acquires that the temperature on the day when the user asks for sick leave is 20 degrees, indicating that 20 degrees is not suitable for the user, so the preset temperature value can be pre-stored as 25 degrees.

For example: when the terminal device detects that the user's body temperature is 39 degrees at 16:30 when the physical education class ends in the class schedule, which has exceeded the normal body temperature range of the human body, it can be determined that the user has just finished the physical education class.

For example: through the five sensors installed inside the terminal device, according to the temperature detection method provided in the embodiment of the present invention, when it is determined that the current ambient temperature is 20 degrees, if it is lower than 25 degrees, it can indicate that the user has entered a cooler air-conditioned room. At this time, the prompt message "You have entered a colder environment, be careful of catching a cold" can be output to remind the user that the current ambient temperature is low, and the screen keeps flashing red until the user leaves the environment with a temperature value of 20 degrees.

This embodiment can output a reminder or flash a red light on the screen to remind the user that the ambient temperature is low when it is detected that the user who has just finished a physical education class enters a colder environment. Generally speaking, children will enter the air-conditioned room as soon as possible when it is relatively hot after physical education, but this will easily get sick. Timely detection of the current ambient temperature and outputting corresponding reminders when the temperature is low can remind the user , so as to avoid users from getting sick to a certain extent.

It should be noted that the form of the prompt information in the embodiment of the present invention may include voice, text, animation or light flashing, etc., which can be set according to actual needs in actual implementation, and is not specifically limited in the embodiment of the present invention.

Embodiment two

As shown in Figure 2, the temperature detection method provided by the embodiment of the present invention may also include the following steps:

201. Acquire reading values of M sensors to obtain M first temperature values.

202. Determine whether there is a direct proportional relationship or an inverse proportional relationship between the M first temperature values and the distances between different sensors and the surface of the terminal device.

In the embodiment of the present invention, for the description of steps 201 to 202, please refer to the detailed description of steps 101 to 102 in Embodiment 1, which will not be repeated in this embodiment of the present invention.

203. If there is an inverse proportional relationship, determine that the temperature of the environment where the terminal device is located rises.

If it is detected that among two adjacent sensors, the reading value of the sensor closer to the surface of the terminal device is larger, and the reading value of the sensor farther away from the surface of the terminal device is smaller, it can indicate that the temperature of the two adjacent sensors before the change The value will be lower than the reading value of the sensor farther from the surface of the terminal device, which can indicate that the reading value of the two sensors is getting higher, that is, the temperature of the environment in which the terminal device is located is increasing.

For example, if sensor A is adjacent to sensor B, and sensor A is closer to the surface of the terminal device than sensor B, if it is detected that the reading value of sensor A is 25 degrees, the reading value of sensor B is 20 degrees, and because the distance from the terminal The reading value of the sensor closer to the surface of the device will change faster, so it can be obtained that the reading value of sensor A and sensor B will be lower than 20 degrees before the change, which means that the reading value of sensor A and sensor B is increasing, that is, the terminal device The temperature of your environment is rising.

In the embodiment of the present invention, adjacent may refer to contact or non-contact. For example, if sensor A is adjacent to sensor B, it may mean that sensor A and sensor B are placed in contact with each other inside the terminal device, and there is no space between them, or it may mean that there is a certain space between sensor A and sensor B. There is no contact, but no other sensors are placed between the two sensors.

204. Output the first prompt message.

After it is determined that the temperature of the environment where the terminal device is located rises, a first prompt message may be output, where the first prompt message is used to prompt that the temperature of the environment where the terminal device is located has increased.

205. If there is a direct proportional relationship, determine that the temperature of the environment where the terminal device is located decreases.

If it is detected that among two adjacent sensors, the reading value of the sensor farther from the surface of the terminal device is larger, and the reading value of the sensor closer to the surface of the terminal device is smaller, it can indicate that the temperature of the two adjacent sensors before the change The value will be higher than the reading value of the sensor farther from the surface of the terminal device, which can indicate that the reading value of the two sensors is getting smaller, that is, the temperature of the environment where the terminal device is located is decreasing.

For example, if sensor A is adjacent to sensor B, and sensor A is closer to the surface of the terminal device than sensor B, if it detects that the reading value of sensor A is 20 degrees, the reading value of sensor B is 25 degrees, and because the distance from the terminal The reading value of the sensor closer to the surface of the device will change faster, so it can be obtained that the reading value of sensor A and sensor B before the change will be higher than 25 degrees, which means that the reading value of sensor A and sensor B is getting smaller, that is, the terminal device The temperature of the environment is decreasing.

206. Output a second prompt message.

After it is determined that the temperature of the environment where the terminal device is located drops, a second prompt message may be output, where the second prompt message is used to prompt that the temperature of the environment where the terminal device is located has dropped.

207. Obtain a temperature parabolic curve according to the M first temperature values.

208. Determine the apex temperature value of the temperature parabolic curve as the ambient temperature value.

209. Output the ambient temperature value.

In the embodiment of the present invention, for the description of steps 207-209, please refer to the detailed description of steps 102-104 in Embodiment 1, which will not be repeated in this embodiment of the present invention.

It should be noted that, in the embodiment of the present invention, steps 203-204 and steps 205-206 are for two different situations of step 202, and will not appear at the same time. Steps 203 to 204 or steps 205 to 206 and steps 207 to 209 can occur simultaneously, or steps 203 to 204 or steps 205 to 206 can be performed first and then steps 207 to 209 can be performed, or steps 207 to 209 can be performed first Steps 203-204 or steps 205-206 are performed again, which is not specifically limited in this embodiment of the present invention.

Similarly, for the output of the first prompt message in step 204 or the output of the second prompt message in step 206 and the output of the ambient temperature value in step 209, the ambient temperature value and the first prompt message or the second prompt message can be output at the same time , or first output the first prompt message or the second prompt message and then output the ambient temperature value, or output the ambient temperature value first and then output the first prompt message or the second prompt message, which is not specifically limited in this embodiment of the present invention.

An embodiment of the present invention provides a temperature detection method. The temperature value obtained by multiple sensors installed inside the terminal device can determine the relationship between the temperature value and the distance between the sensor and the surface of the terminal device. If it is a proportional relationship, it can be determined The current ambient temperature is decreasing. If the relationship is inversely proportional, it can be determined that the current ambient temperature is increasing, and then output different prompt messages and ambient temperature values according to different ambient temperature changes. This technical solution can enable the user to understand the change of the ambient temperature more intuitively, and the detected ambient temperature value is more accurate, and not only the ambient temperature value but also the change of the ambient temperature can be output, which is more intuitive.

As an optional implementation, after fitting the temperature parabolic curve with the temperature value obtained by the sensor installed inside the terminal device and determining the current ambient temperature value, the terminal device can also obtain the average temperature value of the previous day, if the current If the absolute value of the difference between the ambient temperature value and the average temperature value of the previous day is greater than the preset temperature difference value, a prompt message can be sent to the associated guardian device to remind the guardian that the temperature of the user's current environment is different from yesterday's average temperature. The temperature has a relatively large change, which can prompt the guardian to pay attention to the user's clothing or travel situation.

Exemplarily, the preset temperature difference is set according to the local four-season ambient temperature change and the acceptable temperature change value of the human body, and is assumed to be 8 degrees. User A associates User A's mother's mobile phone as a guardian device in the terminal device. If User A's terminal device uses the temperature value obtained by the internal sensor to fit a temperature parabolic curve and determine that the current ambient temperature is 20 degrees , and detected that yesterday’s average temperature was 30 degrees, and today’s ambient temperature has dropped by 10 degrees.

Embodiment three

As shown in Figure 3, the temperature detection method provided by the embodiment of the present invention may also include the following steps:

301. In a constant temperature environment, acquire reading values of M sensors to obtain M second temperature values.

When the terminal device remains turned on and is in a constant temperature environment, reading values of M sensors can be obtained, and M second temperature values can be obtained. The above-mentioned constant temperature environment can be a closed space with constant temperature, or a constant temperature box with a set temperature.

302. Calculate temperature differences between two adjacent sensors to obtain M-1 first differences.

According to the M second temperature values, the temperature difference between two adjacent sensors is calculated, so that M−1 first differences can be obtained.

303. If the M-1 first difference values are all less than the first preset value, acquire the reading values of M sensors to obtain M first temperature values.

Ideally, in a constant temperature environment, due to the balance of heat flow, the reading values of each sensor should be equal, that is, the M first differences are all zero. However, in reality, considering the sensitivity of the sensor and some air flow in the internal space of the terminal device, it will cause weak heat flow, so when the first difference of M-1 is not zero but is less than the first preset value When , it can be considered that the readings of the M sensors are accurate. Then start to acquire the reading values of M sensors, and obtain M first temperature values.

Wherein, the first preset value is an extremely small value set by the terminal device according to objective factors such as the sensitivity of the built-in sensor and the air flow in the internal space of the terminal device, for example, 0.05 degrees, 0.08 degrees.

Exemplarily, assuming that M is 5, the first preset value is 0.05 degrees. If 5 readings can be obtained through the sensors inside the terminal device, the reading value of sensor A is 25.50 degrees, the reading value of sensor B is 25.51 degrees, the reading value of sensor C is 25.51 degrees, and the reading value of sensor D is 25.54 degrees , the reading value of sensor E is 25.56 degrees. Then, four first differences can be obtained through calculation, which are 0.01 degrees, 0 degrees, 0.03 degrees and 0.02 degrees, respectively, and these four first differences are all less than 0.05 degrees, so it can be determined that the five sensors are accurate.

304. If the second difference among the M-1 first differences is greater than or equal to the first preset value, calibrate the temperature values of all sensors according to any second temperature value corresponding to the third difference.

Wherein, the above-mentioned third difference value is any difference value other than the second difference value among the M-1 first difference values.

If there is at least one second difference greater than or equal to the first preset value among the M-1 first difference values, it may indicate that at least one sensor reading corresponding to the second difference value is inaccurate, and calibration is required at this time. All the sensors are calibrated according to the reading value of any one of the two sensors corresponding to the third difference.

Exemplarily, assuming that M is 5, the first preset value is 0.05 degrees. If 5 readings are obtained through the sensors inside the terminal device, the reading value of sensor A is 25.50 degrees, the reading value of sensor B is 25.52 degrees, the reading value of sensor C is 25.59 degrees, and the reading value of sensor D is 25.65 degrees, Sensor E reads 25.68 degrees. Then, four first differences can be obtained through calculation, which are 0.02 degrees, 0.07 degrees, 0.06 degrees, and 0.03 degrees, and two of the second differences, 0.07 degrees and 0.06 degrees, are greater than 0.05 degrees, and calibration is required. At this time, any one of the two third difference values of 0.02 degrees and 0.03 degrees can be used for calibration, taking 0.02 degrees as an example. The readings of the two sensors A and B corresponding to the third difference of 0.02 degrees are 25.50 degrees and 25.52 degrees respectively, then the readings of the five sensors can be calibrated to the reading value of sensor A at 25.50 degrees or the reading value of sensor B 25.52 degrees. Similarly, the third difference of 0.03 degrees can also be used for calibration. The readings of the D and E sensors corresponding to the third difference of 0.03 degrees are 25.65 degrees and 25.68 degrees respectively. At this time, the readings of all sensors are calibrated The reading value of sensor D is 25.65 degrees or the reading value of sensor E is 25.68 degrees.

305. Acquire reading values of M sensors to obtain M first temperature values.

In this embodiment of the present invention, for the description of step 305, please refer to the detailed description of step 101 in Embodiment 1, which will not be repeated in this embodiment of the present invention.

306. Calculate a fourth difference between the first target temperature value and the second target temperature value according to the M first temperature values.

Wherein, the first target temperature value is the reading value of the sensor closest to the surface of the terminal device, and the second target temperature value is the reading value of the sensor farthest from the surface of the terminal device. After the readings of the two sensors are obtained, a fourth difference between them is calculated.

307. If the absolute value of the fourth difference is greater than the second preset value, output third prompt information.

If the absolute value of the fourth difference is greater than the second preset value, it means that the temperature of the external environment has changed greatly. At this time, the third prompt message is output, and the third prompt message is used to prompt the user to add or remove clothes.

Wherein, if the terminal device detects that the reading value of the sensor closest to the surface of the terminal device is greater than the reading value of the sensor farthest from the surface of the terminal device, and the difference between the two is greater than the second preset value, it can be explained that the user is from When the colder environment enters into the hotter environment, and the ambient temperature difference is large, the third prompt message is output at this time, suggesting that the user can take some measures to cool down; if the terminal device detects the reading of the sensor closest to the surface of the terminal device If the value is less than the reading value of the sensor farthest from the surface of the terminal device, and the difference between the two is greater than the second preset value, it means that the user enters from a hotter environment to a cooler environment, and the ambient temperature difference is large , the third prompt message is output at this time, suggesting that the user can take some measures to keep warm.

Exemplarily, the second preset value is set according to the local four-season ambient temperature change and the acceptable temperature change value of the human body, and is assumed to be 8 degrees. When the reading value of sensor A closest to the surface of the terminal device is 26 degrees, and the reading value of sensor B farthest from the surface of the terminal device is 36 degrees, the absolute value of the temperature difference between the two is 10 degrees, greater than 8 degrees, The reading value of sensor A is smaller than the reading value of sensor B, so it can be explained that the user may enter a cooler air-conditioned room from a relatively hot outdoor environment. At this time, the terminal device will output a prompt message to remind the user that the current ambient temperature has greatly increased. increase.

308. Obtain a temperature parabolic curve according to the M first temperature values.

309. Determine the apex temperature value of the temperature parabolic curve as the ambient temperature value.

310. Output the ambient temperature value.

In the embodiment of the present invention, for the description of steps 308-310, please refer to the detailed description of steps 102-104 in Embodiment 1, which will not be repeated in this embodiment of the present invention.

It should be noted that, in the embodiment of the present invention, step 303 and steps 304 to 305 are for two different situations of step 302 and will not appear at the same time. Steps 306 to 307 and steps 308 to 310 can occur simultaneously, or steps 306 to 307 can be performed first and then steps 308 to 310 can be performed, or steps 308 to 310 can be performed first and then steps 306 to 307 can be performed. The present invention Examples are not specifically limited.

Similarly, for the output of the third prompt message in step 307 and the output of the ambient temperature value in step 310, the third prompt message and the ambient temperature value can be output at the same time, or the third prompt message can be output first and then the ambient temperature value can be output , or output the ambient temperature value first and then output the third prompt message, which is not specifically limited in this embodiment of the present invention.

The embodiment of the present invention provides a temperature detection method. Firstly, by obtaining the reading values of each sensor in a constant temperature environment, the difference between every two adjacent sensors is compared. If the difference is less than a certain value, it can indicate that the sensors are all Accurately, this can reduce the sensitivity of the sensor and the influence of the weak air flow inside the terminal device on the detected temperature value, so as to avoid the inaccurate environment temperature value obtained finally. And by comparing the temperature difference between the two sensors closest to and farthest from the surface of the terminal device, the change of the current ambient temperature can be determined, and the user can be directly reminded whether the current ambient temperature is rising or falling.
