Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, for example to a method and device for obtaining calories, an air conditioner and a storage medium. BACKGROUND

[0002] At present, with the development of science and technology, users pay more and more attention to their own health. Wearable devices with physiological monitoring emerge as the times require, for example, smart watches, smart bracelets and smart pillows. Taking a smart watch as an example, when a user wears a smart watch, the smart watch can monitor the user's heart rate, electrocardiogram, sleep curve and calorie consumption in real time. The user can know his or her own physical condition by checking the aforementioned monitoring data, and then make a movement plan according to the physical condition. The calorie consumption can indirectly reflect the energy consumption of the user, so the user has a high requirement for the accuracy of the calculation of the calories.

[0003] In the related art, a method for calculating calories is to obtain personal information and movement data of a wearer of a wearable device, detect whether the wearable device is in a training mode, obtain a detection result, if the detection result represents that the wearable device is in the training mode, input the personal information and a heart rate value into a first calculation model, and calculate a calorie consumption value of the wearer. If the detection result represents that the wearable device is not in the training mode, when a movement level corresponding to a change amount of an acceleration value is greater than a first preset value and a heart rate level corresponding to the heart rate value is less than 1, it is judged whether a step count is less than a third preset value, when the step count is less than the third preset value, the personal information and an acceleration cumulative value are input into a second calculation model, and the calorie consumption value of the wearer is calculated. If the step count is greater than or equal to the third preset value, the personal information, the acceleration cumulative value and a movement speed are input into the second calculation model, and the calorie consumption value of the wearer is calculated.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0005] In the above-mentioned calorie consumption value calculation method, when the heart rate level corresponding to the heart rate value is less than 1, the calorie consumption of the wearer is calculated according to the acceleration cumulative value or the acceleration cumulative value and the movement speed and a preset calculation model. Since the synchronization between the movement acceleration and / or the movement speed and the heart rate fluctuation of the user is low, the above-mentioned calorie consumption value calculation method has low accuracy.

[0030] In the embodiments of the present disclosure, the smart home appliance refers to a home appliance product formed by introducing microprocessors, sensor technology, network communication technology into home appliances, having the characteristics of intelligent control, intelligent sensing and intelligent application. The operation process of the smart home appliance often depends on the application and processing of modern technologies such as the Internet of Things, the Internet and electronic chips. For example, the smart home appliance can realize remote control and management of the smart home appliance by connecting electronic devices.

[0031] In the embodiments of the present disclosure, the terminal device refers to an electronic device with wireless connection function. The terminal device can be connected to the Internet and communicate with the smart home appliance as described above, or can directly communicate with the smart home appliance as described above through Bluetooth, wifi and the like. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a built-in vehicle device in a hovercar, or any combination thereof. The mobile device may, for example, include a mobile phone, a smart home device, a wearable device, a smart mobile device, a virtual reality device, or any combination thereof, wherein the wearable device may, for example, include a smart watch, a smart bracelet, a pedometer, and the like.

[0032] In combination with Figure 1 As shown in the drawings, the present disclosure provides a method for obtaining calories, comprising:

[0033] S01, the air conditioner obtains the current heart rate information and the breathing frequency of the target user. The current heart rate information is detected and generated by the heart rate monitoring device associated with the air conditioner. The breathing frequency is detected and generated by the breathing frequency detection device associated with the air conditioner.

[0034] S02, the air conditioner determines the compensation strategy of the heart rate information according to the continuous state of the current heart rate information and the breathing frequency, and obtains the target heart rate information according to the compensation strategy.

[0035] S03, the air conditioner determines the calories of the target user according to the calorie estimation model corresponding to the target heart rate information.

[0036] By using the method for obtaining the calories provided in the embodiments of the present disclosure, since the respiration frequency and the heart rate information have strong synchronicity, the method determines the compensation strategy of the heart rate information and obtains the target heart rate information according to the continuous state of the current heart rate information and the respiration frequency, so that the actual heart rate value of the target user can be determined more accurately. The calorie consumption value obtained by inputting the target heart rate information into the calorie estimation model has high accuracy.

[0037] At the same time, it is learned from experiments that the acquisition difficulty of the heart rate information is higher than that of the respiration frequency. Moreover, the power consumption of the corresponding device when acquiring the heart rate information is higher than that when acquiring the respiration frequency. Therefore, using the respiration frequency to compensate the information can save the device power consumption.

[0038] It should be noted that the change trend of the respiration frequency and the heart rate information of the target user is roughly consistent. Therefore, when the respiration frequency obtained by the air conditioner increases, the air conditioner sends a control instruction to the heart rate monitoring device to increase the sampling frequency of the heart rate detection. In this way, the heart rate information can be accurately obtained, and the accuracy of the heart rate information capture is improved. As an example, when the respiration frequency of the target user increases from 12 BPM to 16 BPM, the air conditioner sends a control instruction to the smart watch, and the smart watch updates the original sampling frequency from 20 Hz to 100 Hz after receiving the control instruction. Wherein, BPM represents the unit of the heart rate information, which is beats per minute.

[0039] Optionally, in combination with Figure 2 As shown in the figure, the air conditioner determines the compensation strategy of the heart rate information and obtains the target heart rate information according to the current continuous state of the heart rate information and the respiration frequency, including:

[0040] S11, the air conditioner determines the target compensation coefficient according to the rising and falling state of the respiration frequency when the continuous state indicates that the current heart rate information is discontinuous.

[0041] In this step, the current heart rate information is discontinuous, indicating that the heart rate is intermittently lost. At this time, the air conditioner needs to compensate the heart rate information. Since the rising and falling state of the respiration frequency is roughly consistent with the rising and falling state of the heart rate information, the rising and falling state of the heart rate information can be learned by the rising and falling state interval of the respiration frequency, and the corresponding target compensation coefficient is determined.

[0042] S12, the air conditioner multiplies the current heart rate information and the target compensation coefficient to obtain the target heart rate information.

[0043] In this way, the rising and falling of the heart rate information is obtained by the rising and falling state of the breathing frequency, and the target compensation coefficient corresponding to the rising and falling state of the breathing frequency is determined. Then, the following compensation strategy is obtained, and the current heart rate information and the target compensation coefficient are multiplied, so that the target heart rate information is obtained more accurately, thereby providing effective data support for subsequent calorie calculation.

[0044] Optionally, in combination with Figure 3 As shown in the figure, the air conditioner determines the target compensation coefficient according to the rising and falling state of the breathing frequency, including:

[0045] S21, the air conditioner obtains the rising and falling state of the breathing frequency in a first preset time period.

[0046] S22, the air conditioner determines the first compensation coefficient as the target compensation coefficient in the case that the rising and falling state represents that the breathing frequency increases.

[0047] S23, the air conditioner determines the second compensation coefficient as the target compensation coefficient in the case that the rising and falling state represents that the breathing frequency decreases.

[0048] Wherein, the first compensation coefficient is greater than 1, and the second compensation coefficient is less than 1.

[0049] In this way, when the rising and falling state of the breathing frequency represents that the breathing frequency increases, the estimated heart rate information is also in the rising state, so the first compensation coefficient greater than 1 is determined as the target compensation coefficient. When the rising and falling state of the breathing frequency represents that the breathing frequency decreases, the estimated heart rate information is also in the falling state, so the first compensation coefficient less than 1 is determined as the target compensation coefficient.

[0050] Specifically, the first compensation coefficient is greater than 1 and less than or equal to 1.2, and the second compensation coefficient is less than 1 and less than or equal to 0.85. For example, the first compensation coefficient is 1.15 or 1.2. The second compensation coefficient is 0.9 or 0.95.

[0051] It should be noted that when the breathing frequency is in a maintaining state in the first preset time period, it indicates that the target user's breathing is in a relatively stable state, and correspondingly, the estimated heart rate information is also relatively stable. At this time, the target compensation coefficient can be determined as 1, or the target compensation coefficient can be determined as a coefficient value close to 1, for example, 1.02 or 1.05.

[0052] Optionally, the current heart rate information is determined to be discontinuous in the following manner:

[0053] No heart rate information is received in a second preset time period.

[0054] In this way, when the target user wears the smart watch to monitor the heart rate, there is a case that the smart watch is not correctly worn or is temporarily taken off due to a decrease in tightness of wearing, and at this time, the air conditioner cannot receive the heart rate information from the smart watch, so it can be determined that the current heart rate information is discontinuous.

[0055] As an example, the second preset time period is 2 minutes, the air conditioner only receives the heart rate information in the first minute within 2 minutes, and the heart rate information required after 1 minute is not successfully received. At this time, the air conditioner can determine that the current heart rate information is discontinuous, and the heart rate compensation processing is performed by using the breathing frequency.

[0056] In combination Figure 4 The embodiment of the present disclosure provides a method for obtaining calories, comprising:

[0057] S31, the air conditioner obtains the current heart rate information and the breathing frequency of the target user.

[0058] S32, the air conditioner determines the compensation strategy of the heart rate information according to the continuous state of the current heart rate information and the breathing frequency, and obtains the target heart rate information according to the compensation strategy.

[0059] S33, the air conditioner obtains the current movement speed of the user and the first calorie estimation model corresponding to the target heart rate information when the current heart rate information is greater than the lower limit threshold of heart rate.

[0060] S34, the air conditioner inputs the current movement speed and the target heart rate information into the first calorie estimation model corresponding to the target heart rate information to determine the calories of the target user.

[0061] By using the method for obtaining calories provided by the embodiment of the present disclosure, when the current heart rate information is greater than the lower limit threshold of heart rate, it indicates that the reliability of the current heart rate information is high. The air conditioner obtains the current movement speed of the user and inputs it and the target heart rate information into the first calorie estimation model corresponding to the target heart rate information to calculate the calories, so as to accurately obtain the calorie consumption value of the target user.

[0062] As an example, the first calorie estimation model uses the following Meeus model:

[0063]

[0064] Wherein, respectively represent the movement speed, the target heart rate information and the calories corresponding to the first calorie estimation model. The unit of movement speed is meter / second.

[0065] Since the Meeus model has a range of application limit for heart rate information, when the Meeus model is used to calculate the calories, the lower limit threshold of heart rate is set to 60 BPM.

[0066] In combination Figure 5 As shown in the embodiments of the present disclosure, a method for obtaining calories is provided, comprising:

[0067] S41, the air conditioner obtains current heart rate information and breathing frequency of a target user.

[0068] S42, the air conditioner determines a compensation strategy of the heart rate information according to the continuous state of the current heart rate information and the breathing frequency, and obtains target heart rate information according to the compensation strategy.

[0069] S43, the air conditioner obtains current movement speed of the user in the case that the current heart rate information is less than or equal to a lower limit threshold of heart rate.

[0070] S44, the air conditioner inputs the current movement speed to a second calorie estimation model corresponding to the target heart rate information, and determines calories of the target user.

[0071] By using the method for obtaining calories provided by the embodiments of the present disclosure, when the target user moves in place or performs a movement with small movement amplitude and / or small movement intensity in the room, the current heart rate information value is usually small, specifically, the current heart rate information is less than or equal to the lower limit threshold of heart rate. If the first calorie estimation model is used to calculate the calories, the accuracy of the obtained calorie consumption is low. At this time, the second calorie estimation model corresponding to the target heart rate information is used, that is, only the current movement speed is used to obtain the calories of the target user, so that the calorie consumption value of the target user under low intensity movement is accurately obtained.

[0072] As an example, the second calorie model uses the following Meeus model:

[0073]

[0074] wherein, represents the calories corresponding to the second calorie model. The meaning of is as described above.

[0075] The embodiments of the present disclosure also provide an air conditioner, comprising a breathing frequency detection device and a controller. The breathing frequency detection device is used to obtain the breathing frequency of a target user. The controller is used to obtain current heart rate information and breathing frequency of the target user, the current heart rate information is generated by a heart rate monitoring device associated with the air conditioner, and a compensation strategy of the heart rate information is determined according to the continuous state of the current heart rate information and the breathing frequency, and target heart rate information is obtained according to the compensation strategy, and the calories of the target user are determined according to a calorie estimation model corresponding to the target heart rate information.

[0076] By using the air conditioner provided by the embodiments of the present disclosure, the accuracy of the calculation of the calorie consumption value can be improved.

[0077] Optionally, the respiration frequency detection device can be a millimeter wave radar, which receives the feedback signal sent by the user and generates the respiration frequency of the user after signal processing of the detection signal sent by the millimeter wave radar. The respiration frequency detection device can also be obtained by using thermal imaging technology. For example, the respiration frequency detection device obtains a visible light image and a thermal image, analyzes the foregoing images, obtains temperature information of the user's respiration area through the visible light image and the thermal image with a matching relationship, and determines the respiration frequency of the user according to the temperature information. The specific implementation of the respiration frequency detection device in the present disclosure can not be specifically limited.
