The embodiment of the invention provides a temperature detection method and terminal equipment, which can quickly and accurately detect the external environment temperature of a user and output a temperature value.

The terminal device according to the embodiment of the present invention may be a Mobile phone, a tablet Computer, a notebook Computer, a palm Computer, a vehicle-mounted terminal device, a wearable device, an Ultra-Mobile Personal Computer (UMPC), a netbook, or a Personal Digital Assistant (PDA). The wearable device may be a smart watch, a smart bracelet, a watch phone, a smart foot ring, a smart earring, a smart necklace, a smart headset, or the like, and the embodiment of the present invention is not limited.

An execution main body of the temperature detection method provided in the embodiment of the present invention may be the terminal device, or may also be a functional module and/or a functional entity that can implement the temperature detection method in the terminal device, and may be specifically determined according to actual use requirements, which is not limited in the embodiment of the present invention. The following takes a terminal device as an example to exemplarily explain the temperature detection method provided by the embodiment of the present invention.

The temperature detection method provided by the embodiment of the invention can be applied to the scene of temperature change caused by sudden change of the environment where the user is located.

Example one

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

101. and acquiring the reading values of the M sensors to obtain M first temperature values.

The terminal equipment is internally provided with M sensors, the distances between different sensors and the surface of the terminal equipment are different, and M is an integer greater than or equal to 3. At any moment, reading values of a first sensor, a second sensor, \ 8230and an Mth sensor are respectively obtained to obtain M first temperature values.

In the embodiment of the present invention, taking a terminal device as an example, as shown in fig. 1b, M sensors are disposed inside a terminal device 11, and because the surface of the terminal device is exposed to the air, the distance between each sensor and a surface 12 of the terminal device needs to be different, for example, only M sensors are disposed in a space inside the terminal device near a surface where a display 13 is located, and a certain distance exists between any two sensors, and the distance may be a fixed distance or a flexibly set distance. Reading values of a first sensor, a second sensor, \ 8230and an Mth sensor are respectively obtained at any moment so as to obtain M first temperature values at the moment.

However, facing the wearable device, since the wearable device may have a part of the surface contacting with the human body and not be exposed to the air, each sensor provided in the wearable device only needs to have a different distance from a certain plane where the display screen of the wearable device is located. Taking a telephone watch as an example, as shown in fig. 1c, M sensors are arranged inside the watch body 14 of the telephone watch, each sensor being at a different distance from the watch body's case 16 from the bottom plate 15 of the watch body to the middle region of the watch body's case 16, there being a certain distance between any two sensors. Reading values of a first sensor, a second sensor, \ 8230and an Mth sensor are respectively obtained at any moment so as to obtain M first temperature values at the moment.

Optionally, before obtaining the reading values of the M sensors, the terminal device may further detect whether the terminal device is in a wearing state, and if the terminal device is detected to be in the wearing state, perform steps 101 to 105 according to the sensor setting in fig. 1 c. If the terminal device is detected not to be in a wearing state, the temperature detection is carried out only by the sensor close to the surface where the display screen is located according to the sensor arrangement in fig. 1b, and the steps 101 to 105 are carried out.

102. And judging whether the M first temperature values and the distances between different sensors and the surface of the terminal equipment have a direct proportion relation or an inverse proportion relation.

In the embodiment of the invention, the relation between the temperature value and the distance between the sensor and the surface of the terminal device can be determined by the M first temperature values and the distances between the M sensors and the surface of the terminal device. In the M sensors, each sensor has a reading value, and the reading value of each sensor and the distance between each sensor and the surface of the terminal equipment are in one-to-one correspondence, and then the relationship between the reading value of each sensor and the distance between each sensor and the surface of the terminal equipment is determined.

It can be understood that when a user is in a fixed environment for a period of time, no heat flows inside the terminal device, the reading values of the plurality of sensors inside the terminal device should be the same, and when the user suddenly leaves the fixed environment and enters a new environment, the external environment temperature changes, which may 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 the sensor is to the external environment, the faster the temperature change speed will be; conversely, the farther the sensor is from the surface of the terminal device, the farther away from the environment, the slower the temperature change will be. It can therefore be stated that the reading of the sensor which is closer to the surface of the terminal changes more rapidly, i.e. the value changes more rapidly, whether the temperature of the environment increases or decreases.

103. If a direct proportion relation or an inverse proportion relation exists, a temperature parabolic curve is obtained by adopting least square fitting according to the M first temperature values.

If the M first temperature values and the distances between the different sensors and the surface of the terminal equipment have a direct proportional relationship or an inverse proportional relationship, it can be determined that the user leaves the fixed environment and enters a brand new environment with different temperatures. At the moment, curve fitting is carried out through a least square algorithm according to the M temperature values at the same moment, and a temperature parabolic curve can be obtained. The abscissa of the temperature parabolic curve is the distance between the sensor and the surface of the terminal device, and the ordinate of the temperature parabolic curve is the temperature value. Curve fitting is a data processing method for approximately depicting a curve composed of a plurality of discrete points and representing the functional relationship among the points by using a continuous curve.

In the embodiment of the invention, a plurality of data points p are obtained by acquiring the reading values of M sensors and associating the reading values with the distance between the sensor and the surface of the terminal equipment _i (x _i ，y _i ) Which isWhere i =1,2, \8230:, k (3 ≦ k ≦ M), and then approximate curves y = φ (x) for the k data points, in order to minimize the deviation between the approximate curves and each data point, a least squares method is required, which can determine a temperature parabolic curve according to the principle of minimum sum of squares of deviations and fitting of a polynomial.

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 parabolic curve of the temperature obtained by fitting needs to have the smallest difference with the temperature value of each data point as much as possible, so that the sum of squares of the difference between the ordinate value of each data point and the curve needs to be obtained, as shown in the following formula (2):

then, the partial derivative is calculated for the sum of squared differences, and the following formulas (3), (4), (5) and the like can be obtained:

then, the following formulas (6), (7) and (8) can be obtained by respectively simplifying the formulas (3), (4) and (5):

then, the equations (6), (7) and (8) are expressed in a matrix form, and the equation (9) can be obtained:

simplifying each matrix in equation (9) can result in equation (10):

i.e. X a = Y, so a = (X '× X-1 × X' × Y), which results in the coefficient matrix a, i.e. a ₀ ，a ₁ ，…，a _k The temperature parabolic curve can be obtained by substituting the value of (2) into the fitting polynomial (1).

104. And determining the vertex temperature value of the temperature parabolic curve as the environment temperature value.

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

If the user enters the environment with low temperature from the environment with high temperature, the temperature parabolic curve is a parabola which is firstly decreased and then increased, the opening is upward, as shown in fig. 1d, and the temperature value corresponding to the lowest point of the temperature parabolic curve can be determined as the ambient temperature value; if the user enters the environment with high temperature from the environment with low temperature, the temperature parabolic curve is a parabola which is increased and then decreased, the opening is downward, and as shown in fig. 1e, the temperature value corresponding to the highest point of the temperature parabolic curve can be determined as the ambient temperature value.

105. And outputting the ambient temperature value.

The embodiment of the invention provides a temperature detection method, which comprises the steps of obtaining a plurality of temperature values by obtaining reading values of a plurality of sensors arranged in terminal equipment at the same time, if a certain direct proportional relation or inverse proportional relation exists between the plurality of temperature values and the distance between the sensors and the surface of the terminal equipment, then showing that the current environment temperature of a user is changed to a certain degree, fitting a temperature parabolic curve according to the plurality of temperature values, determining the temperature value corresponding to the vertex of the curve as an environment temperature value, and finally outputting the environment temperature value. According to the technical scheme, after the current environment temperature of the user is detected to be changed to a certain degree, the reading value of the sensor does not need to be stable, the accurate environment temperature value can be quickly obtained by acquiring the reading values of the plurality of sensors at any moment, and the temperature of the current environment of the user is reminded.

As an optional implementation manner, the terminal device may further obtain the readings of M sensors at N times to obtain N × M first temperature values; obtaining a temperature parabolic curve according to the M first temperature values at each moment so as to obtain N temperature parabolic curves; respectively obtaining the vertex temperature value of each temperature parabolic curve to obtain N vertex temperature values; and taking the average value of the N vertex temperature values as an environment temperature value, and outputting the environment temperature value.

In this optional embodiment, the terminal device may obtain a plurality of temperature values at a plurality of times, and then average the temperature values corresponding to the vertexes determined at each time, so as to obtain the ambient temperature value. According to the scheme, the final environment temperature value is obtained by averaging a plurality of temperature values, so that the environment temperature can be detected more accurately, and the condition that the environment temperature value is inaccurate due to insufficient sensitivity of the sensor is avoided.

As an optional implementation manner, the terminal device may further obtain the schedule information of the user, and if it is detected that the body temperature of the user is increased and is higher than the normal body temperature range of the human body at the end time of the physical education session, it may be indicated that the user has just ended the physical education session, at this time, the readings of the M sensors may be obtained to obtain M first temperature values, and a temperature parabolic curve is obtained according to the M first temperature values, and a vertex temperature value of the temperature parabolic curve is determined as the environmental temperature value. And comparing the environment temperature value with a preset temperature value, and if the environment temperature value is lower than the preset temperature value, outputting a fourth prompt message to prompt a user that the current environment temperature is lower and a cold risk exists. Optionally, if the ambient temperature value is lower than the preset temperature value, the terminal device may further control the screen to send a red light warning to prompt the user.

Illustratively, the preset temperature value is a pre-stored temperature that is sensed by the user to be suitable (for example, it may be a temperature value lower than the normal body temperature of the human body), and the preset temperature value may be set by the terminal device according to the local geographical location of the user, the season, and user information (which may include a medical record of the user, a curriculum schedule, etc.), or may be set by the user.

For example: when the terminal device acquires that the temperature of a user on a certain day is 20 degrees when the user asks for illness and faking, which indicates that 20 degrees is relatively cold and unsuitable for the user, the preset temperature value can be prestored as 25 degrees.

For example: when the terminal device detects that the body temperature of the user is 39 degrees and exceeds the normal body temperature range of the human body at the end time 16 of the physical education course in the schedule, the terminal device can determine that the user just finishes the physical education course.

For example: according to the temperature detection method provided by the embodiment of the invention, 5 sensors arranged in the terminal equipment determine that the current environment temperature is 20 ℃ and is lower than 25 ℃, so that the user can be shown to enter a cooler air-conditioning room, at the moment, a prompt message of 'entering the cooler environment and being careful to catch a cold' can be output to prompt the user that the current environment temperature is lower, and the screen continuously flickers red light until the user leaves the environment with the temperature value of 20 ℃.

The embodiment can output a prompt or flash red light on a screen to prompt a user that the temperature of the environment is low when the user who just finished a physical class enters a cold environment. Generally speaking, children can enter the air-conditioned room as soon as possible after finishing a physical education course when the children are hot, but the children are prone to getting ill, the current environment temperature is detected timely, and a corresponding prompt is output when the temperature is low, so that the user can be prompted, and the user can be prevented from getting ill to a certain extent.

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

Example two

As shown in fig. 2, the temperature detection method provided in the embodiment of the present invention may further include the following steps:

201. and acquiring the reading values of the M sensors to obtain M first temperature values.

202. And judging whether the M first temperature values and the distances between different sensors and the surface of the terminal equipment have a direct proportion relation or an inverse proportion relation.

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 the first embodiment, which is not repeated herein.

203. And if the inverse proportional relation exists, determining the temperature rise of the environment where the terminal equipment is located.

If the reading value of the sensor closer to the surface of the terminal device is larger and the reading value of the sensor farther from the surface of the terminal device is smaller in the two adjacent sensors, it can be shown that the temperature value before the change of the two adjacent sensors is lower than the reading value of the sensor farther from the surface of the terminal device, and thus it can be shown that the reading values of the two sensors are becoming larger, that is, the temperature of the environment where the terminal device is located is rising.

Illustratively, if sensor a and sensor B are adjacent, sensor a is closer to the surface of the terminal device than sensor B, and if it is detected that the reading value of sensor a is 25 degrees and the reading value of sensor B is 20 degrees, and because the reading value of the sensor closer to the surface of the terminal device changes faster, it can be obtained that the reading value before the change of sensor a and sensor B is lower than 20 degrees, it indicates that the reading values of sensor a and sensor B are becoming larger, i.e. the temperature of the environment in which the terminal device is located is increasing.

In the embodiments of the present invention, adjacent may refer to contact or not contact. For example: the sensor a and the sensor B are adjacent to each other, which may mean that the sensor a and the sensor B are in contact arrangement inside the terminal device, and there is no space interval therebetween, or that there is a certain space interval between the sensor a and the sensor B, and there is no contact, but there is no other sensor disposed between the two sensors.

204. And outputting the first prompt message.

After determining that the temperature of the environment in which the terminal device is located is increased, a first prompt message for prompting the temperature increase of the environment in which the terminal device is located may be output.

205. And if the direct proportional relation exists, determining that the temperature of the environment where the terminal equipment is located is reduced.

If it is detected that 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 in the two adjacent sensors, it can be said that the temperature value before the change of the two adjacent sensors is higher than the reading value of the sensor farther from the surface of the terminal device, which can indicate that the reading values of the two sensors are becoming smaller, that is, the temperature of the environment where the terminal device is located is decreasing.

Illustratively, if sensor a and sensor B are adjacent, sensor a is closer to the surface of the terminal device than sensor B, if the reading value of sensor a is detected to be 20 degrees, the reading value of sensor B is 25 degrees, and since the reading value of the sensor closer to the surface of the terminal device changes faster, the reading value before the change of sensor a and sensor B can be obtained to be higher than 25 degrees, which indicates that the reading values of sensor a and sensor B are becoming smaller, i.e. the temperature of the environment in which the terminal device is located is decreasing.

206. And outputting the second prompting message.

After determining that the temperature of the environment in which the terminal device is located decreases, a second prompt message for prompting the temperature decrease of the environment in which the terminal device is located may be output.

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

208. And determining the vertex temperature value of the temperature parabolic curve as the environment temperature value.

209. And outputting the ambient temperature value.

In the embodiment of the present invention, for the description of steps 207 to 209, please refer to the detailed description of steps 102 to 104 in the first embodiment, and the details of the embodiment of the present invention are not repeated.

It should be noted that, in the embodiment of the present invention, steps 203 to 204 and steps 205 to 206 are two different cases of step 202, and do not occur at the same time. Steps 203 to 204 or steps 205 to 206 and steps 207 to 209 may occur simultaneously, or steps 203 to 204 or steps 205 to 206 may be performed first followed by steps 207 to 209, or steps 207 to 209 may be performed first followed by steps 203 to 204 or steps 205 to 206, and the embodiment of the present invention is not particularly limited.

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

The embodiment of the invention provides a temperature detection method, which can determine the relationship between a temperature value and the distance between a sensor and the surface of terminal equipment through temperature values obtained by a plurality of sensors arranged in the terminal equipment, can determine that the current environment temperature is reduced if the temperature value is in a direct proportion relationship, can determine that the current environment temperature is increased if the temperature value is in an inverse proportion relationship, and then outputs different prompt messages and environment temperature values according to different environment temperature changes.

EXAMPLE III

As shown in fig. 3, the temperature detection method provided in the embodiment of the present invention may further include the following steps:

301. and in a constant temperature environment, reading values of the M sensors are obtained to obtain M second temperature values.

When the terminal equipment keeps the starting state in the constant temperature environment, the reading values of the M sensors can be obtained, and M second temperature values can be obtained. The constant temperature environment may be a closed space with a constant temperature or a thermostat with a set temperature.

302. And calculating the temperature difference value of two adjacently arranged sensors to obtain M-1 first difference values.

And calculating the temperature difference between two adjacent sensors according to the M second temperature values, so as to obtain M-1 first difference values.

303. And if the M-1 first difference values are all smaller than the first preset value, acquiring the reading values of the M sensors to obtain M first temperature values.

In an ideal situation, the readings of the sensors should be equal in a constant temperature environment because the heat flow is balanced, i.e. the M first differences are all zero. However, in practical situations, considering that the sensitivity of the sensors and a part of air flowing in the internal space of the terminal device may cause a weak heat flow, when the M-1 first differences are not zero but are all smaller than the first preset value, the readings of the M sensors may be considered to be accurate. And then, reading values of the M sensors are obtained to obtain M first temperature values.

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

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

304. And if a second difference value in the M-1 first difference values is larger than or equal to a first preset value, calibrating the temperature values of all the sensors according to any second temperature value corresponding to the third difference value.

Wherein the third difference is any one difference other than the second difference among the M-1 first differences.

If at least one second difference value which is greater than or equal to the first preset value exists in the M-1 first difference values, it can be shown that at least one sensor reading corresponding to the second difference value is inaccurate, and calibration is needed at this time. And calibrating all the sensors according to the reading value of any one of the two sensors corresponding to the third difference value.

Illustratively, assuming that M is 5, the first preset value is 0.05 degrees. If 5 readings are obtained through the sensor in the terminal device, the reading of the sensor A is 25.50 degrees, the reading of the sensor B is 25.52 degrees, the reading of the sensor C is 25.59 degrees, the reading of the sensor D is 25.65 degrees, and the reading of the sensor E is 25.68 degrees. Then 4 first differences, 0.02 degrees, 0.07 degrees, 0.06 degrees, and 0.03 degrees can be calculated, wherein if two second differences, 0.07 degrees and 0.06 degrees, are greater than 0.05 degrees, calibration is required. In this case, the calibration may be performed by taking any one of the two third differences of 0.02 degree and 0.03 degree, for example, 0.02 degree. The readings of the two sensors a and B corresponding to the third difference of 0.02 degree are 25.50 degrees and 25.52 degrees, respectively, and the readings of the five sensors can be calibrated to be 25.50 degrees of the reading of the sensor a or 25.52 degrees of the reading of the sensor B. Similarly, the third difference 0.03 degree may be used for calibration, where the readings of the two sensors D and E corresponding to the third difference 0.03 degree are 25.65 degrees and 25.68 degrees, respectively, and then the readings of all the sensors are calibrated to be 25.65 degrees of the reading of the sensor D or 25.68 degrees of the reading of the sensor E.

305. And acquiring the reading values of the M sensors to obtain M first temperature values.

In the embodiment of the present invention, for the description of step 305, please refer to the detailed description of step 101 in the first embodiment, which is not repeated herein.

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

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

307. And if the absolute value of the fourth difference is greater than the second preset value, outputting third prompt information.

If the absolute value of the fourth difference is larger than the second preset value, the temperature of the external environment is changed greatly, and at the moment, third prompt information is output and used for prompting a user to increase or decrease clothes.

If the terminal device detects that the reading value of the sensor closest to the surface of the terminal device is larger than the reading value of the sensor farthest from the surface of the terminal device, and the difference value between the reading value and the reading value is larger than a second preset value, it can be said that the user enters a hotter environment from a cooler environment, and the environmental temperature difference is larger, at this moment, a third prompt message is output, and the user is advised to take some measures to cool; if the terminal device detects that the reading value of the sensor closest to the surface of the terminal device is smaller than the reading value of the sensor farthest from the surface of the terminal device, and the difference value between the reading value and the reading value is larger than the second preset value, it can be stated that the user enters a cooler environment from a hotter environment, the environment temperature difference is large, at this moment, a third prompt message is output, and the user is advised to take some measures to keep warm.

Illustratively, the second preset value is set according to the local four-season environmental temperature change and the acceptable temperature change value of the human body, and is assumed to be 8 degrees. When the reading value of the sensor A closest to the surface of the terminal equipment is 26 degrees, the reading value of the sensor B farthest from the surface of the terminal equipment is 36 degrees, the absolute value of the temperature difference between the reading value of the sensor A and the reading value of the sensor B is 10 degrees and is larger than 8 degrees, and the reading value of the sensor A is smaller than the reading value of the sensor B, the situation that a user possibly enters a cooler air-conditioned room from a warmer outdoor environment can be shown, and at the moment, the terminal equipment can output a prompt message to prompt the user that the current environment temperature is greatly increased.

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

309. And determining the vertex temperature value of the temperature parabolic curve as the environment temperature value.

310. And outputting the ambient temperature value.

In the embodiment of the present invention, for the descriptions of steps 308 to 310, please refer to the detailed descriptions of steps 102 to 104 in the first embodiment, which is not described again in the embodiment of the present invention.

It should be noted that, in the embodiment of the present invention, the

steps

303 and 304 to 305 are two different cases of the step 302, and do not occur at the same time. The steps 306 to 307 and the steps 308 to 310 may be performed simultaneously, or the steps 306 to 307 may be performed first and then the steps 308 to 310 may be performed, or the steps 308 to 310 may be performed first and then the steps 306 to 307 may be performed, and the embodiment of the present invention is not particularly limited.

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

And comparing the temperature value difference between the two sensors closest to and farthest from the surface of the terminal equipment, so that the change of the current environment temperature can be determined, and the user can be directly reminded whether the current environment temperature is increased or decreased.
