Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a flowchart of a temperature measurement method according to an embodiment of the present disclosure.
The specific steps may include:
s101: if the wrist-lifting action of the wrist-worn device wearer is detected, acquiring the alternative environment temperature acquired by the first temperature sensor according to a preset period;
wherein, this embodiment can be applied to wrist and wear equipment, and wrist wears equipment and can include intelligent bracelet, intelligent wrist-watch etc.. The wrist-worn equipment can comprise a motion detection device, and whether a wrist-lifting action exists for a wearer of the wrist-worn equipment is judged according to a motion signal collected by the motion detection device. Specifically, the motion detection device can include acceleration sensor and gyroscope, and this embodiment can judge whether the wearer lifts the wrist according to the acceleration signal that acceleration sensor gathered and the angular velocity signal that the gyroscope gathered.
After detecting the wrist lifting action of the wrist wearing device wearer, the alternative environment temperature collected by the first temperature sensor can be acquired according to a preset period. First temperature sensor in this embodiment can be contact temperature sensor for gather wrist-worn equipment's equipment casing temperature, equipment casing can be the great material of coefficient of heat conductivity (like metal copper, stainless steel etc.) manufacturing, consequently when wrist-worn equipment is in the stable environment of a certain temperature for a long time, wrist-worn equipment's equipment casing temperature is the same with the temperature of environment of being located. The present embodiment may use the device case temperature collected by the first temperature sensor as the alternative ambient temperature.
S102: determining a target time period according to the change trend of the alternative environment temperature;
the wrist-mounted device is usually worn on the wrist part, so that the wrist-mounted device is located inside the sleeves when the wearer does not lift the wrist, and the wrist-mounted device is exposed to the external environment from inside the sleeves when the wearer lifts the wrist, so that the alternative environment temperature detected by the first temperature sensor when the wearer lifts the sleeves will change. For example, in an environment of 40 degrees celsius, the alternative ambient temperature will exhibit an increasing trend of change after the wearer lifts his wrist; in an environment of-20 degrees celsius, the alternative ambient temperature will exhibit a decreasing trend of change after the wearer lifts his wrist. After the wrist is lifted, the alternative environment temperature approaches the temperature of the environment where the wrist-worn device is located no matter the alternative environment temperature is increased or decreased, and finally the trend of change is stable.
The target time period is determined according to the change trend of the alternative environment temperature, the change trend of the alternative environment temperature corresponding to the target time period is not an increasing trend or a decreasing trend, and the time span of the target time period is larger than or equal to the preset time length. The target time period is a time period when the alternative environment temperature is equal to the temperature of the environment where the wrist-worn device is located. The definition of the incremental trend in this embodiment may be: the alternative environment temperature detected after each time in the target time period is higher than the alternative environment temperature detected before; the definition of the decreasing trend in this embodiment may be: each later detected alternate ambient temperature within the target time period is lower than the previously detected alternate ambient temperature. The value of the corresponding candidate ambient temperature for the target time period may be a plurality of discrete temperature values. The definition of the incremental trend in this embodiment may also be: and the variation trend of the fitting curve of all the alternative environment temperatures in the target time period along with the time variation is within a preset interval.
S103: and determining the actual environment temperature according to the alternative environment temperature corresponding to the target time period.
After the target time period in which the candidate environment temperature is stable is determined, the present embodiment may determine the actual environment temperature according to the candidate environment temperature corresponding to the target time period. In determining the actual ambient temperature, excessive or insufficient ambient temperature may be removed in order to reduce measurement errors.
On the basis that obtains actual ambient temperature, user's body surface temperature that the second temperature sensor that this embodiment can utilize wrist-worn equipment gathered to revise user's body surface temperature according to actual ambient temperature, obtain user's actual body temperature. The second temperature sensor can be thermopile temperature sensor (a non-contact temperature sensor), can utilize thermopile temperature sensor to measure user's body surface temperature, because user's body surface temperature often receives ambient temperature's influence, consequently this embodiment revises user body surface temperature according to actual ambient temperature and obtains user's actual body temperature (like oral cavity temperature, armpit temperature or rectum temperature etc.), and then carries out accurate evaluation to user's physiological conditions according to user's actual body temperature.
In the embodiment, after the wrist-lifting action of the wrist-worn device wearer is detected, the alternative environment temperature collected by the first temperature sensor is obtained for multiple times according to the preset period, and if the temperature in the sleeve of the wearer is different from the external environment, the change trend of the alternative environment temperature collected by the first temperature sensor after the wrist of the wearer is lifted is a gradual increase rate or a gradual decrease. In this embodiment, a target time period in which the time span is greater than or equal to the preset time length and the change trend is not increasing or decreasing is selected according to the change trend of the candidate temperature, that is, the candidate ambient temperature collected by the first temperature sensor in the target time period changes smoothly and approaches to the real ambient temperature, and further, the actual ambient temperature may be determined according to the candidate ambient temperature corresponding to the target time period. According to the wrist-worn equipment measuring method and device, the error of measuring the ambient temperature when the wrist-worn equipment is exposed to the external environment from the interior of the sleeve can be eliminated, and the accuracy of measuring the ambient temperature is improved.
As a further introduction to the corresponding embodiment in fig. 1, after obtaining the alternative ambient temperature in the target time period, the process of determining the actual ambient temperature according to the alternative ambient temperature corresponding to the target time period may include: removing the invalid alternative environment temperature from the alternative environment temperatures corresponding to the target time period to obtain an effective alternative environment temperature; and taking the average value of the effective alternative environment temperatures as the actual environment temperature. The invalid alternative environment temperature is the alternative environment temperature corresponding to the target time period in which the absolute value of the difference between the invalid alternative environment temperature and the temperature median is greater than the preset temperature difference, and the temperature median is the median of all the alternative environment temperatures in the target time period.
Referring to fig. 2, fig. 2 is a flowchart of a method for analyzing a candidate ambient temperature trend provided in an embodiment of the present application, where the embodiment further describes S102 in the embodiment corresponding to fig. 1, and a further implementation may be obtained by combining the embodiment with the embodiment corresponding to fig. 1, where the embodiment may include the following steps:
s201: determining the number of acquired alternative ambient temperatures;
the obtained alternative environment temperature may be the alternative environment temperature obtained by the first temperature sensor according to a preset period after the wrist raising motion is detected, an initial value of the number of the obtained alternative environment temperatures is 0, and 1 is added to the number of the obtained alternative environment temperatures every preset period.
S202: if the number of the acquired alternative environment temperatures is larger than the preset number, adding the acquired alternative environment temperatures to a temperature value set, and clearing the number of the acquired alternative environment temperatures;
before this step, an operation of judging that the number of the acquired alternative ambient temperatures is greater than a preset number may exist, and if the number of the acquired alternative ambient temperatures is greater than the preset number, the acquired alternative ambient temperatures are added to the temperature value set so as to analyze a change trend of all the alternative ambient temperatures in the temperature value set along with time. The present embodiment may zero the number of acquired candidate ambient temperatures while adding the acquired candidate ambient temperatures to the temperature value set, so as to record the number of newly acquired candidate ambient temperatures.
S203: judging whether the trend of the alternative environment temperature in the temperature value set changing along with the time is an increasing trend or a decreasing trend; if so, clearing the alternative environment temperatures in the temperature value set, and entering a step of determining the number of the acquired alternative environment temperatures; if not, entering S204;
s204: and taking the time period corresponding to the alternative environment temperature in the temperature value set as a target time period.
After the candidate environment temperatures in the temperature value set are determined to increase or decrease with time, this embodiment indicates that the candidate environment temperatures in the temperature value set at this time have not reached a steady state and cannot reflect the real environment temperature, and the candidate environment temperatures in the temperature value set may be cleared, and the step of determining the number of the acquired candidate environment temperatures in S201 may be performed again. If the alternative environment temperature in the temperature value set is judged to be increased or decreased along with the time, the alternative environment temperature in the temperature value set at the moment is shown to be in a stable state, the alternative environment temperature in the temperature set can reflect the real environment temperature, and the time period corresponding to the alternative environment temperature in the temperature value set at the moment can be used as the target time period. It is understood that the number of the alternative ambient temperatures in the temperature set should be greater than the number of the ambient temperatures by a preset number, and the preset number is equal to the number of the preset periods included in the preset time period in the embodiment corresponding to fig. 1.
As a further introduction to the corresponding embodiment of fig. 2, after determining that the trend of the alternative ambient temperature over time within the set of temperature values is an increasing trend or a decreasing trend, a prompt message indicating that the current ambient temperature measurement has an error may also be generated. Specifically, can vibrate or report the prompt tone through wrist-worn equipment in this embodiment and remind the user that there is the error in the current ambient temperature measurement.
Referring to fig. 3, fig. 3 is a flowchart of another method for analyzing alternative ambient temperature trends according to an embodiment of the present application, where this embodiment further describes S102 in the embodiment corresponding to fig. 1, and a further implementation may be obtained by combining this embodiment with the embodiment corresponding to fig. 1, where this embodiment may include the following steps:
s301: determining a period statistical parameter;
the period statistical parameter mentioned in this embodiment is information describing a period number of continuous discrete (non-increasing or decreasing) alternative environment temperatures acquired according to a preset period after the wrist raising motion is detected, and an initial value of the period statistical parameter is 2;
s302: judging whether the trend of the change of the alternative environment temperature along with the time collected in the (i-2) th period, the (i-1) th period and the (i) th period is an increasing trend or a decreasing trend; if yes, entering S303; if not, entering S304;
in the embodiment, at least three periods of acquired alternative environment temperatures are needed to determine whether the trend of the random time change of the alternative environment temperatures is an increasing trend or a decreasing trend, i is a period number, i is greater than 2, the ith period is the current period, and the alternative environment temperature acquired in the 1 st period is the alternative environment temperature acquired by the first temperature sensor at the wrist lifting moment.
S303: performing a preset operation on the value of the period statistical parameter;
based on determining whether the trend of the alternative environment temperature collected in the (i-2) th cycle, the (i-1) th cycle and the (i) th cycle along with the change of the time is an increasing trend or a decreasing trend, the current value of the cycle statistical parameter can be reduced by one (namely, the cycle number of the continuous discrete alternative environment temperature is reduced by one), and if the current value of the cycle statistical parameter is 2, the current value can be kept unchanged. Specifically, the preset operation performed on the value of the period statistic parameter in this embodiment may include: and judging whether the current value of the period statistical parameter is greater than 2, if so, subtracting 1 from the value of the period statistical parameter, and if so, keeping the current value of the period statistical parameter unchanged.
S304: adding 1 to the value of the period statistical parameter;
the step is established on the basis that the trend of the change of the alternative environment temperature along with the time collected in the (i-2) th cycle, the (i-1) th cycle and the (i) th cycle is determined not to be an increasing trend or a decreasing trend, and the current value of the cycle statistical parameter can be added with one, namely the cycle number of the continuous discrete alternative environment temperature is added with 1. The larger the value of the period statistical parameter is, the more the alternative environment temperature approaches the true environment temperature.
S305: judging whether the value of the period statistical parameter is greater than or equal to a reference value N; if yes, entering S306; if not, adding 1 to the value of i and entering S302;
s306: and taking the time period corresponding to the current period and N-1 periods before the current period as a target time period.
Before the step, an operation of judging whether the value of the period statistical parameter is greater than or equal to the reference value N may also exist, and if the value of the period statistical parameter is greater than or equal to the reference value N, the time periods corresponding to the current period and N-1 periods before the current period are taken as the target time periods.
The implementation process of the above embodiment is described below by using a specific example, if the alternative environment temperature of the 1 st cycle is 30 degrees celsius and the alternative environment temperature of the 2 nd cycle is 32 degrees celsius, at this time, if the alternative environment temperature of the 3 rd cycle is detected to be 31 degrees celsius, the value of the cycle statistical parameter is updated to be 3, and at this time, if the alternative environment temperature of the 3 rd cycle is detected to be 33 degrees celsius, the value of the cycle statistical parameter is 2. If the alternative environment temperature of the 5 th cycle is 30 degrees celsius, the alternative environment temperature of the 6 th cycle is 32 degrees celsius, and the value of the cycle statistical parameter in the 6 th cycle is 4, at this time, if the alternative environment temperature of the 7 th cycle is 31 degrees celsius, the value of the cycle statistical parameter is updated to 3, the value of the reference value N is 5, at this time, if the alternative environment temperature of the 7 th cycle is 33 degrees celsius, the value of the cycle statistical parameter is updated to 3, at this time, if the alternative environment temperature of the 7 th cycle is 31 degrees celsius, the value of the cycle statistical parameter is updated to 5, and the time period corresponding to the 3 rd cycle to the 7 th cycle is taken as the target time period.

Wherein the temperature mean T0 at the time of wrist lifting may be a temperature reading of the first contact temperature sensor. Detecting a lift in a motion state detection moduleThe wrist action state is started, the wearable device is in the ascending motion state until the wearable device is static (at the moment, a user aligns a receiving window of a thermopile sensor of the wearable device to the forehead), and n temperature readings are obtained within the period T1, wherein T is the period a1 ,T a2 ,T a3 ,T a4 ,…,T an . If the above-mentioned T a1 ,T a2 ,T a3 ,T a4 ,…,T an The readings show an increasing or decreasing trend, the microprocessor reminds the user that the accurate ambient temperature is not obtained at the moment in a certain mode (such as vibration, image display or sound playing) and needs the user to keep the wearable device exposed in the air environment, and the microprocessor continues to obtain the temperature readings of the contact temperature sensor at intervals of delta T until n temperature readings, T 'are obtained again in time T2' a1 ,T’ a2 ,T’ a3 ,T’ a4 ,…,T’ an .

If there are only a few k discrete differences from the median in the readings above, the absolute value is greater than Δ T m0.5 The data of (2) can be discarded as invalid data. Averaging the remaining readings to obtain an ambient temperature average (i.e., the actual ambient temperature mentioned above), the ambient temperature average T a ＝(T’ a1 +T’ a2 +T’ a3 +T’ a4 +…+T’ an ) And (n-k) as ambient temperature for subsequent data processing.
After the motion state detection module detects that the wearable device is static and obtains the ambient temperature mean value, the microprocessor continuously reads the readings T of the thermopile temperature sensor for m times f1 ,T f2 ,T f3 ,T f4 ,…,T fm . The microprocessor utilizes the environment temperature mean value T obtained by the steps a And readings T of m thermopile temperature sensors f1 ,T f2 ,T f3 ,T f4 ,…,T fm Calculating to obtain the body temperature T of the human body through a certain environment temperature compensation algorithm b1 ,T b2 ,T b3 ,T b4 ,…,T bm 。
