Detailed Description
The core of the application lies in providing an intelligent bracelet and a comfortable judgement method of heat and device to improve the accuracy to user's temperature travelling comfort judgement result effectively, thereby ensure the rationality of the ambient temperature that the user is located, ensure that the user is healthy.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and 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.
The embodiment of the application discloses a thermal comfort judgment method, which mainly comprises the following steps as shown in figure 1:
s101: receiving a detection value of a human physiological parameter of a target object sent by a sensor; the human physiological parameters include heart rate and skin impedance.
Specifically, the thermal comfort determination method provided by the present application does not directly collect temperature data of a target object and perform determination in combination with a uniform temperature setting range as in the prior art, but performs determination based on human physiological parameters such as heart rate and skin impedance that can represent physiological activity states of an organism.
It should be noted that, in order to ensure the accuracy of the thermal comfort determination result, the present application specifically combines the heart rate and the skin impedance detection value for determination. Wherein, the heart rate is the beating number of times of heart in unit interval, and the beating of heart is the energy source that maintains each item life activity, and the heart rate also directly relates to human comfort to have close relation with the temperature: when the temperature rises, the metabolism speed of the human body is accelerated, and the heart rate rises; when the temperature is lowered, the metabolism speed of the human body is slowed down, and the heart rate is lowered.
Skin impedance is a parameter directly related to skin water and oil content, and like heart rate, skin impedance is also affected by temperature: when the temperature rises, the metabolism speed of skin cells is increased, the water and sweat as metabolites are increased, and the skin impedance is reduced; when the temperature drops, the metabolism speed of skin cells is reduced, the water and sweat as metabolites are reduced, and the skin impedance is increased.
Both heart rate and skin impedance are directly related to the comfort of the human body: when the heart rate is too fast, a human body can feel shortness of breath and heart overload; when the heart rate is too slow, the human body feels weak qi; too high skin impedance usually reflects more sweating, at which time the body feels "hotter"; too low skin impedance generally reflects a slow metabolism, at which the human body feels "cooler". Therefore, the heart rate and the skin impedance can be used as the physiological state of the target object to the current temperature to reflect whether the target object feels comfortable to the current temperature.
The heart rate can be detected by a heart rate sensor; the skin impedance may in particular be detected by a corresponding skin impedance sensor. Generally, the skin impedance sensor detects an equivalent impedance value of the skin based on electrical signals such as a test voltage, so as to obtain the skin impedance, and accurately reflect the metabolic state of skin cells. Further, the thermal comfort judgment method provided by the application can be applied to an intelligent bracelet, and the intelligent bracelet can integrate a heart rate sensor and a skin impedance sensor.
S102: and acquiring a reasonable value range of the human physiological parameters.
S103: and judging whether the current temperature is in the comfortable temperature range of the target object or not according to the comparison result of the detection value and the reasonable value range.
Specifically, after the detection values of the heart rate and the skin impedance are obtained, the respective detection values can be respectively compared according to the respective corresponding reasonable value ranges of the heart rate and the skin impedance, so as to determine whether the target object feels comfortable at the current temperature according to the specific conditions of the heart rate and the skin impedance, that is, determine whether the current temperature is within the comfortable temperature range of the target object.
It should be noted that besides the parameters closely related to temperature, such as heart rate and skin impedance, the person skilled in the art may add other physiological parameters related to temperature, such as blood oxygen concentration, blood flow velocity, etc., which is not limited in this application.
According to the thermal comfort judgment method, the detection value of the human physiological parameter of the target object sent by the sensor is received; the human physiological parameters comprise heart rate and skin impedance; acquiring a reasonable value range of the human physiological parameters; therefore, whether the current temperature is within the comfortable temperature range of the target object or not is judged according to the comparison result of the detection value and the reasonable value range. Therefore, the method and the device have the advantages that the physiological parameters such as the heart rate and the skin impedance are utilized to directly reflect the comfort level of the human body, indirect detection of the current temperature is achieved, the condition that different target objects are set with fixed temperature threshold ranges is avoided, the method and the device are effectively suitable for the conditions that different target objects have different temperature tolerance degrees, the accuracy of a judgment result is improved, the rationality of the environment temperature where a user is located can be ensured, and the health of the user is guaranteed.
On the basis of the above contents, as a preferred embodiment, the method for determining whether the current temperature is within the comfortable temperature range of the target object according to the comparison result between the detection value and the reasonable value range includes:
if the heart rate detection value is higher than the upper limit value of the reasonable heart rate value range and the skin impedance detection value is lower than the lower limit value of the reasonable skin impedance value range, judging that the current temperature is higher than the comfortable temperature range of the target object;
and if the heart rate detection value is lower than the lower limit value of the reasonable heart rate value range and the skin impedance detection value is higher than the upper limit value of the reasonable skin impedance value range, judging that the current temperature is lower than the comfortable temperature range of the target object.
Specifically, considering that the heart rate is increased when the patient is frightened, the skin impedance after bathing is reduced, and the like, in order to improve the accuracy of the determination result and eliminate the false detection condition, the present embodiment can perform the thermal comfort determination by combining the heart rate and the skin impedance at the same time: that is, only when the heart rate detection value is high and the skin impedance detection value is low, it is determined that the current temperature is higher than (the upper limit temperature of) the comfortable temperature range of the target subject; and determining that the current temperature is lower than (the lower limit temperature of) the comfortable temperature range of the target subject only when the heart rate detection value is low and the skin impedance detection value is high.
As another preferred embodiment, the method for determining thermal comfort according to the present application, wherein the determining whether the current temperature is within the comfortable temperature range of the target object according to the comparison result between the detection value and the reasonable value range includes:
calculating a first relative error between the heart rate detection value and a central value of a heart rate reasonable value range;
calculating a second relative error between the skin impedance detection value and a central value of a reasonable value range of the skin impedance;
according to δ ═ α1·δ1+α2·δ2Calculating a comprehensive error delta; wherein, delta1Is a first relative error; delta2Is the second relative error; alpha is alpha1More than 0 is a first preset weight; alpha is alpha2If the weight is less than 0, the second preset weight is obtained;
if the comprehensive error is larger than a preset positive threshold, judging that the current temperature is higher than the comfortable temperature range of the target object;
and if the comprehensive error is smaller than the preset negative threshold, judging that the current temperature is lower than the comfortable temperature range of the target object.
Specifically, considering that the heart rate and the skin impedance of different people may reflect different degrees of temperature changes, for example, when the temperature of some groups (for example, people with weak heart and lung functions) changes, the heart rate changes obviously but the skin impedance changes insignificantly, and when the temperature of some groups (for example, people with strong heart and lung functions) changes, the heart rate changes insignificantly but the skin impedance changes obviously, in order to further improve the judgment accuracy, the method and the device can also perform weighted calculation on the comparison result of the heart rate and the skin impedance, that is, according to the first relative error δ1And a second relative error delta2And obtaining the comprehensive error delta, and further performing thermal comfort judgment according to the comprehensive error delta. Among them, there are:
δ1＝(c-c0)/c0；
δ2＝(r-r0)/r0；
c is a heart rate detection value; c. C0The heart rate is the central value of the reasonable value range of the heart rate; r is a skin impedance detection value; r is0The central value of the reasonable value range of the skin impedance.
It is noted that the change of the skin impedance is directly related to the change of the temperature due to the positive correlation between the heart rate and the temperatureTo change the negative correlation, and therefore, the first relative error delta1Corresponding first preset weight alpha1Set to a positive value and will deviate from the second relative error delta2Corresponding second preset weight alpha2Set to a negative value. Therefore, when the temperature is higher, the combined error delta should be larger than a certain positive threshold value theoretically; when the temperature is lower, the combined error delta is negative theoretically and is smaller than a certain negative threshold value. The reasonable preset positive threshold value and the preset negative threshold value can be set by the person skilled in the art according to the actual situation.
On the basis of the above contents, as a preferred embodiment, the method for judging thermal comfort, which is provided by the application, for obtaining the reasonable value range of the human physiological parameter includes:
receiving an input ideal value of a human physiological parameter;
and determining a reasonable value range according to the ideal value and the preset fluctuation error.
Specifically, the present embodiment further adds a setting function for a reasonable value range of the human physiological parameter, that is, the user inputs an ideal value of the human physiological parameter of the target object, and determines the reasonable value range by taking the ideal value as a center of the interval and a preset fluctuation error as a radius of the interval.
For the smart band, the ideal value of the human physiological parameter input by the user can be received through an input device such as a key or a touch screen.
On the basis of the above, as a preferred embodiment, before determining the reasonable value range according to the ideal value and the preset fluctuation error, the method further includes:
acquiring the gender of a target object;
and determining a corresponding preset fluctuation error according to the gender of the target object.
Specifically, considering that there are differences in physiology between men and women, the fat content in the subcutaneous and cell of women is generally higher than that in men, so that different preset fluctuation errors can be adopted according to sex to determine the reasonable value range of human physiological parameters.
On the basis of the above, as a preferred embodiment, the method for determining thermal comfort further includes, after determining that the current temperature is not within the comfort temperature range of the target object:
and generating and outputting a warning instruction to the warning device.
Specifically, after the comfort level of the target object for the current temperature is determined to be poor, warning can be performed through the warning device so as to inform a guardian and the like in time. Further, in the application scenario of the smart band, the alarm device recommends but is not limited to any one or any combination of a buzzer, a vibrator, and an indicator light.
It is easily understood that the skilled person can further set two warning devices to warn that the current temperature is higher than the comfortable temperature range and the current temperature is lower than the comfortable temperature range, respectively.
On the basis of the above, as a preferred embodiment, the method for determining thermal comfort further includes, after determining that the current temperature is not within the comfort temperature range of the target object:
and sending the generated adjusting instruction to a temperature control system by using a wireless communication module.
Specifically, in this embodiment, an adjustment instruction may be further sent to the temperature control system based on the determination result, so as to automatically implement timely adjustment of the temperature, and ensure that the temperature is within the comfortable temperature range of the target object. The temperature control system can be used for controlling equipment such as an air conditioner, a fan, a humidifier and the like, and the adjusting instruction can be specific to environmental parameters such as temperature, humidity, wind speed, wind direction and the like. The wireless communication module can be specifically a WIFI module, a Bluetooth module and the like.
