Description

Technical Field

[0001] The present invention relates to the field of air conditioning technology, and more specifically, to an air conditioning control method based on millimeter wave radar, an air conditioner applying the air conditioning control method based on millimeter wave radar, and a computer-readable storage medium applying the air conditioning control method based on millimeter wave radar. Background Art

[0002] With the acceleration of modern life and the development of science and technology, people pay more and more attention to the comfort and health of their living environment. Traditional air-conditioning control systems mainly rely on environmental parameters such as temperature and humidity, and cannot be adjusted intelligently according to the actual physiological state of the human body. In recent years, millimeter-wave radar technology has shown broad application prospects in the fields of medical health, smart home, etc. due to its high precision, non-contact monitoring and strong penetration ability.

[0003] In an existing air conditioning control method, during the operation of the air conditioner, the user's breathing frequency is monitored by using a millimeter-wave radar, and the corresponding operating parameters are determined according to the user's breathing frequency and the user's preset reference frequency, so as to control the air conditioner to operate according to the operating parameters, improve the fit between the operating status of the air conditioner and the user's physical condition and activity status, and more accurately and intelligently implement parameter adjustment that varies from person to person, thereby improving the user experience. However, this solution only uses the breathing frequency to adjust the operating parameters of the air conditioner, with fewer reference parameters, and the comfort of air conditioning adjustment is poor. In another air conditioning control method, the breathing frequency and heart rate of people in the space environment are detected by a millimeter-wave radar, and the type of people in the space environment is determined according to the characteristics of the breathing frequency and heart rate, and the corresponding control mode is selected according to the type of people, so as to realize intelligent control of the air conditioner. However, it is difficult for the millimeter-wave radar to detect the heart rate, and the heart rate is affected by many factors and fluctuates greatly. The accuracy of using the heart rate for air conditioning adjustment is poor.

[0004] Therefore, it is necessary to consider a more optimized air-conditioning control method based on millimeter-wave radar. Summary of the invention

[0005] The first object of the present invention is to provide an air conditioning control method based on millimeter wave radar that can accurately identify different breathing states and improve the accuracy and reliability of monitoring.

[0006] The second object of the present invention is to provide an air conditioner that can accurately identify different breathing states and improve the accuracy and reliability of monitoring.

[0007] The third object of the present invention is to provide a computer-readable storage medium that can accurately identify different respiratory states and improve the accuracy and reliability of monitoring.

[0008] In order to achieve the above-mentioned first purpose, the air-conditioning control method based on millimeter-wave radar provided by the present invention includes: obtaining the current breathing frequency and current breathing amplitude of the target user through the millimeter-wave radar; confirming the current breathing state of the target user according to the current breathing frequency and current breathing amplitude; and adjusting the operating state of the air conditioner according to the current breathing state.

[0009] It can be seen from the above scheme that the air conditioning control method based on millimeter wave radar of the present invention adopts breathing frequency and amplitude as the control parameters of air conditioning regulation, and it is relatively easy for millimeter wave radar to obtain breathing data. And the breathing frequency and amplitude can directly reflect the human body's demand for cold and heat, and air comfort. By obtaining the user's breathing frequency and amplitude in real time, different breathing states can be accurately identified, so as to confirm the breathing state in real time, and then realize the real-time dynamic adjustment of the air conditioning operation state, and improve the accuracy and reliability of monitoring.

[0010] In a further scheme, the step of confirming the current breathing state of the target user based on the current breathing frequency and the current breathing amplitude includes: if the current breathing frequency is less than the first preset breathing frequency and the current breathing amplitude is less than the first preset amplitude, the current breathing state is in a shallow and slow breathing state; if the current breathing frequency is less than the first preset breathing frequency and the current breathing amplitude is greater than the second preset amplitude, the current breathing state is in a shallow and fast breathing state; if the current breathing frequency is greater than or equal to the first preset breathing frequency and less than or equal to the second preset breathing frequency, and the current breathing amplitude is greater than or equal to the first preset amplitude and less than or equal to the second preset amplitude, the current breathing state is in a normal state; if the current breathing frequency is greater than the second preset breathing frequency and the current breathing amplitude is less than the first preset amplitude, the current breathing state is in a deep and slow breathing state; if the current breathing frequency is greater than the second preset breathing frequency and the current breathing amplitude is greater than the second preset amplitude, the current breathing state is in a deep and fast breathing state.

[0011] It can be seen that by setting different preset values ​​for the breathing frequency and breathing amplitude, and combining various states such as shallow and slow breathing, shallow and fast breathing, normal breathing, deep and slow breathing, deep and fast breathing, etc., through precise breathing state judgment, the air conditioner can adjust the operating state more accurately.

[0012] In a further solution, the step of adjusting the operating state of the air conditioner according to the current breathing state includes: adjusting at least one of the following parameters of the air conditioner according to the current breathing state: target temperature, windshield, and fresh air switch state.

[0013] It can be seen that by adjusting the target temperature, windshield and fresh air switch status of the air conditioner, multi-dimensional adjustments can be made to optimize the indoor environment in all aspects, accurately meet the user's needs for temperature, wind speed and air quality under different breathing states, and significantly improve the user's comfort.

[0014] In a further scheme, the step of adjusting the operating state of the air conditioner according to the current breathing state includes: if the current breathing state is in a slow breathing state, the target temperature is controlled to increase gradually until the target temperature is greater than or equal to a preset temperature upper limit value, and the slow breathing state includes a shallow slow breathing state and a deep slow breathing state; if the current breathing state is in a normal state, the target temperature maintains the current temperature; if the current breathing state is in a fast breathing state, the target temperature is controlled to decrease gradually until the target temperature is less than or equal to a preset temperature lower limit value, and the fast breathing state includes a shallow fast breathing state and a deep fast breathing state.

[0015] It can be seen that dynamically adjusting the target temperature according to the breathing state fully takes into account the different temperature requirements that the human body may have under different breathing states. The temperature gradually rises in the slow breathing state, gradually cools down in the fast breathing state, and maintains the current temperature in the normal state. This adjustment method fits the relationship between the human physiological state and temperature perception, providing users with a more humane and comfortable temperature environment. Slow breathing may suggest that the user is in a state of relative relaxation or a slight drop in body temperature. At this time, gradually increasing the temperature can help maintain physical comfort; fast breathing may indicate that the user feels hot, and gradually lowering the temperature can relieve discomfort in time. Through this precise matching, the physical burden caused by temperature discomfort is avoided, and the user's comfort and health experience are improved.

[0016] In a further scheme, the step of controlling the target temperature to gradually increase includes: if the current breathing state is in a shallow and slow breathing state, then controlling the target temperature to increase by a first preset temperature amplitude at every first preset time interval; if the current breathing state is in a deep and slow breathing state, then controlling the target temperature to increase by a second preset temperature amplitude at every second preset time interval, wherein the second preset temperature amplitude is smaller than the first preset temperature amplitude.

[0017] It can be seen that shallow and slow breathing and deep and slow breathing reflect different degrees of relaxation or low metabolic state. In the state of shallow and slow breathing, the human body may consume relatively more calories. By increasing the first preset temperature amplitude at each interval of the first preset time, the temperature is increased at a relatively fast rate, which can meet the human body's need for a warm environment in a timely manner. Deep and slow breathing usually means that the human body is in a deeper state of relaxation and the heat consumption is slower. At this time, increasing the second preset temperature amplitude by a smaller amount at each interval of the second preset time can avoid causing discomfort to the human body due to excessive temperature increase, and accurately adapt to the physiological needs of the human body under different breathing states.

[0018] In a further scheme, the step of controlling the target temperature to gradually decrease includes: if the current breathing state is in a shallow and rapid breathing state, then controlling the target temperature to decrease by a third preset temperature amplitude at every third preset time interval; if the current breathing state is in a deep and rapid breathing state, then controlling the target temperature to decrease by a fourth preset temperature amplitude at every fourth preset time interval, wherein the third preset temperature amplitude is smaller than the fourth preset temperature amplitude.

[0019] It can be seen that shallow and rapid breathing and deep and rapid breathing reflect different degrees of stress or overheating in the human body. The human body may only feel slightly uncomfortable during shallow and rapid breathing. Reducing the third preset temperature amplitude at each third preset time interval can reduce the temperature in a relatively gentle manner, which can avoid excessive stimulation to the body caused by cooling too quickly. Deep and rapid breathing indicates that the human body is in a relatively hot or stressed state. At this time, reducing the fourth preset temperature amplitude by a larger amount at each fourth preset time interval can reduce the ambient temperature faster, meet the body's urgent need for coolness, and accurately match the physiological needs of the human body under different breathing states.

[0020] In a further scheme, the step of adjusting the operating state of the air conditioner according to the current breathing state also includes: if the current breathing state is in a shallow and slow breathing state, the windshield of the indoor fan of the air conditioner is controlled to reduce the first preset gear amplitude based on the current windshield; if the current breathing state is in a deep and slow breathing state, the windshield of the indoor fan of the air conditioner is controlled to reduce the second preset gear amplitude based on the current windshield, wherein the second preset gear amplitude is smaller than the first preset gear amplitude; if the current breathing state is in a normal state, the windshield of the indoor fan of the air conditioner is controlled to maintain the current windshield; if the current breathing state is in a shallow and fast breathing state, the windshield of the indoor fan of the air conditioner is controlled to increase the third preset gear amplitude based on the current windshield; if the current breathing state is in a deep and fast breathing state, the windshield of the indoor fan of the air conditioner is controlled to increase the fourth preset gear amplitude based on the current windshield, wherein the third preset gear amplitude is smaller than the fourth preset gear amplitude.

[0021] It can be seen that shallow and slow breathing and deep and slow breathing usually mean that the human body is in a relatively relaxed state. At this time, lowering the fan windshield can reduce the impact of air flow on the human body and avoid affecting the relaxation state due to strong airflow interference. Different reduction ranges are set for shallow and slow breathing and deep and slow breathing. The reduction range is smaller during deep and slow breathing, because people in deep and slow breathing may be more sensitive to environmental changes. Such fine adjustment is more in line with the human body's needs for the environment during deep relaxation. Shallow and fast breathing and deep and fast breathing reflect that the human body may be in different degrees of dryness and heat. Appropriately increasing the windshield during shallow and fast breathing can bring a certain amount of air flow to help dissipate heat and relieve slight dryness and heat; increasing the windshield more significantly during deep and fast breathing can accelerate air flow, quickly take away the body's heat, and meet the body's need for coolness in a hot state. Through this differentiated adjustment, the human body's needs for wind speed at different degrees of heat sensation can be accurately matched.

[0022] In a further scheme, the step of adjusting the operating state of the air conditioner according to the current breathing state also includes: if the current breathing state is in a shallow and slow breathing state, a deep and slow breathing state, or a normal state, closing the fresh air duct; if the current breathing state is in a shallow and fast breathing state or a deep and fast breathing state, opening the fresh air duct.

[0023] It can be seen that when the user is in a state of shallow slow, deep slow or normal breathing, it indicates that the indoor environment is relatively comfortable and the human body does not urgently need changes in air quality. At this time, closing the fresh air channel can reduce unnecessary energy loss. However, shallow fast or deep fast breathing may indicate that the indoor air is not good or the human body's metabolism is accelerated and the demand for fresh air increases. Opening the fresh air channel can timely introduce fresh air, expel stale air, improve air quality, and meet the human body's demand for air quality in different states.

[0024] In order to achieve the second purpose of the present invention, the present invention provides an air conditioner including a processor and a memory, the memory stores a computer program, and when the computer program is executed by the processor, the steps of the above-mentioned air conditioning control method based on millimeter wave radar are implemented.

[0025] In order to achieve the third purpose of the present invention, the present invention provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a controller, the steps of the above-mentioned air conditioning control method based on millimeter wave radar are implemented.

[0027] Figure 2 It is a flow chart of an embodiment of an air conditioning control method based on millimeter wave radar of the present invention.

[0028] The present invention is further described below in conjunction with the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0029] The air conditioning control method based on millimeter wave radar of the present invention is a computer program applied to the air conditioner, which is used to adjust the operating state of the air conditioner. Figure 1 As shown, the air conditioner includes a main controller 1 and a millimeter wave radar 2. The millimeter wave radar 2 is used to obtain the breathing state of the human body in the physical space where the air conditioner is located, and the main controller 1 is used to control the operating state of the air conditioner according to the breathing state.

[0030] Air conditioning control method embodiment based on millimeter wave radar:

[0031] See also Figure 2In this embodiment, when the air conditioning control method based on the millimeter wave radar is working, step S1 is first executed to obtain the current breathing frequency and current breathing amplitude of the target user through the millimeter wave radar. When the air conditioner is in operation, in order to improve the user experience, it is necessary to obtain the user's breathing state so as to adjust the operation state of the air conditioner according to the user's breathing state. Therefore, the raw data is obtained by the millimeter wave radar, and then the breathing frequency and breathing amplitude are extracted by FFT (Fast Fourier Transform) and filtering technology. This is a well-known technology for those skilled in the art and will not be repeated here.

[0032] After obtaining the current breathing frequency and current breathing amplitude of the target user, step S2 is executed to confirm the current breathing state of the target user according to the current breathing frequency and current breathing amplitude. The breathing frequency and amplitude can directly reflect the human body's needs for heat and cold and air comfort. In order to achieve personalized control of the air conditioner, it is necessary to confirm the current breathing state of the target user according to the breathing frequency and amplitude to adjust the operating state of the air conditioner. Different users have different breathing states in different scenarios. The air conditioner is adjusted accordingly to meet the personalized needs of the user and improve the user's comfort experience.

[0033] In this embodiment, the step of confirming the current breathing state of the target user according to the current breathing frequency and the current breathing amplitude includes: if the current breathing frequency is less than the first preset breathing frequency and the current breathing amplitude is less than the first preset amplitude, the current breathing state is in a shallow and slow breathing state; if the current breathing frequency is less than the first preset breathing frequency and the current breathing amplitude is greater than the second preset amplitude, the current breathing state is in a shallow and fast breathing state; if the current breathing frequency is greater than or equal to the first preset breathing frequency and less than or equal to the second preset breathing frequency, the current breathing amplitude is greater than or equal to the first preset amplitude and less than or equal to the second preset amplitude, the current breathing state is in a normal state; if the current breathing frequency is greater than the second preset breathing frequency and the current breathing amplitude is less than the first preset amplitude, the current breathing state is in a deep and slow breathing state; if the current breathing frequency is greater than the second preset breathing frequency and the current breathing amplitude is greater than the second preset amplitude, the current breathing state is in a deep and fast breathing state. Among them, the first preset breathing frequency, the second preset breathing frequency, the first preset amplitude and the second preset amplitude can be preset according to experimental data, for example, the first preset breathing frequency is 12 times / minute, the second preset breathing frequency is 20 times / minute, the first preset amplitude is 0.5 cm, and the second preset amplitude is 1.5 cm.

[0034] By setting different preset values ​​for breathing frequency and breathing amplitude, various states such as shallow and slow breathing, shallow and fast breathing, normal breathing, deep and slow breathing, and deep and fast breathing are combined accordingly. The shallow and slow breathing state indicates that the user is in deep relaxation, early sleep, or relatively weak physical condition. The shallow and fast breathing state may be that the user has just done a little exercise and the body has not yet completely calmed down, or is in a state of mild anxiety or tension, resulting in a large increase in the breathing frequency although the breathing frequency has not increased significantly. The normal state indicates that the user's physical state is relatively stable and is in a normal state of activity or rest. The deep and slow breathing state may occur when the user is doing specific relaxation activities such as deep meditation and yoga. The breathing frequency is accelerated but the amplitude is small, and the body is in a special state of relaxation and regulation. The deep and fast breathing state means that the user has just experienced strenuous exercise, or the body is in a state of stress, such as emotional excitement, illness and fever, etc. The body needs to meet the oxygen demand by speeding up and deepening breathing. Through accurate breathing state judgment, the air conditioner can adjust the operating state more accurately.

[0035] After confirming the current breathing state of the target user, step S3 is executed to adjust the operating state of the air conditioner according to the current breathing state. The breathing state is an intuitive physiological feedback of the human body to the comfort of the surrounding environment. The breathing states of different users in the same environment may be different, and the breathing states of the same user at different times and activities may also be different. Adjusting the air conditioner based on the breathing state can achieve personalized indoor environment control and meet the unique needs of each user at a specific moment.

[0036] In this embodiment, the step of adjusting the operating state of the air conditioner according to the current breathing state includes: adjusting at least one of the following parameters of the air conditioner according to the current breathing state: target temperature, windshield, and fresh air switch state. By adjusting the target temperature, windshield, and fresh air switch state of the air conditioner, multi-dimensional adjustments can be made to optimize the indoor environment in all directions, accurately meet the user's needs for temperature, wind speed, and air quality under different breathing states, and significantly improve the user's comfort.

[0037] In this embodiment, the step of adjusting the operating state of the air conditioner according to the current breathing state includes: if the current breathing state is in a slow breathing state, the target temperature is controlled to increase gradually until the target temperature is greater than or equal to the preset temperature upper limit; if the current breathing state is in a normal state, the target temperature is maintained at the current temperature; if the current breathing state is in a fast breathing state, the target temperature is controlled to decrease gradually until the target temperature is less than or equal to the preset temperature lower limit. Among them, the preset temperature upper limit is the target temperature value plus 1°C, and the preset temperature lower limit is the target temperature value minus 1°C. The target temperature is dynamically adjusted according to the breathing state, taking into full account the different temperature requirements that the human body may have under different breathing states. The temperature is gradually increased in the slow breathing state, gradually decreased in the fast breathing state, and the current temperature is maintained in the normal state. This adjustment method fits the relationship between the physiological state of the human body and the temperature perception, and provides users with a more humane and comfortable temperature environment. Slow breathing may indicate that the user is in a relatively relaxed state or the body temperature is slightly reduced. At this time, gradually increasing the temperature helps to maintain physical comfort; fast breathing may indicate that the user feels hot, and gradually reducing the temperature can relieve discomfort in time. Through this precise matching, the physical burden caused by temperature discomfort is avoided, and the user's comfort and health experience are improved.

[0038] In this embodiment, the step of gradually increasing the target temperature includes: if the current breathing state is in a shallow and slow breathing state, the target temperature is controlled to increase by a first preset temperature amplitude every first preset time interval; if the current breathing state is in a deep and slow breathing state, the target temperature is controlled to increase by a second preset temperature amplitude every second preset time interval, wherein the second preset temperature amplitude is less than the first preset temperature amplitude. The first preset time interval, the second preset time interval, the first preset temperature amplitude and the second preset temperature amplitude can all be pre-set according to experimental data. For example, the first preset time interval and the second preset time interval are both 10 minutes, the first preset temperature amplitude is 0.2°C, and the second preset temperature amplitude is 0.1°C. Shallow and slow breathing and deep and slow breathing reflect different degrees of relaxation or low metabolic state. In the shallow and slow breathing state, the heat consumption of the human body may be relatively large. The first preset temperature amplitude is increased every first preset time interval, and the temperature is increased at a relatively fast rate, which can meet the human body's demand for a warm environment in a timely manner. Deep and slow breathing usually means that the human body is in a deeper state of relaxation and heat consumption is slower. At this time, increasing the temperature by a smaller second preset temperature amplitude every second preset time interval can avoid causing discomfort to the human body due to excessive temperature increase, and accurately adapt to the physiological needs of the human body under different breathing states.

[0039] In this embodiment, the step of gradually reducing the target temperature includes: if the current breathing state is in a shallow and fast breathing state, the target temperature is controlled to reduce the third preset temperature amplitude every third preset time interval; if the current breathing state is in a deep and fast breathing state, the target temperature is controlled to reduce the fourth preset temperature amplitude every fourth preset time interval, wherein the third preset temperature amplitude is less than the fourth preset temperature amplitude. The third preset time, the fourth preset time, the third preset temperature amplitude, the fourth preset temperature amplitude and the preset temperature upper limit can all be preset according to experimental data. For example, the third preset time and the fourth preset time are both 10 minutes, the third preset temperature amplitude is 0.2°C, and the fourth preset temperature amplitude is 0.1°C. Shallow and fast breathing and deep and fast breathing reflect different degrees of stress or overheating of the human body. The human body may only be slightly uncomfortable during shallow and fast breathing. Reducing the third preset temperature amplitude every third preset time interval can reduce the temperature in a relatively mild manner, which can avoid excessive stimulation to the body caused by excessive cooling. Deep and rapid breathing indicates that the human body is in a relatively hot or stressed state. At this time, reducing the fourth preset temperature by a larger amplitude every fourth preset time interval can reduce the ambient temperature more quickly, meet the body's urgent need for coolness, and accurately match the physiological needs of the human body under different breathing states.

[0040] In this embodiment, the step of adjusting the operating state of the air conditioner according to the current breathing state also includes: if the current breathing state is in a shallow and slow breathing state, the windshield of the indoor fan of the air conditioner is controlled to reduce the first preset gear amplitude based on the current windshield; if the current breathing state is in a deep and slow breathing state, the windshield of the indoor fan of the air conditioner is controlled to reduce the second preset gear amplitude based on the current windshield, wherein the second preset gear amplitude is smaller than the first preset gear amplitude; if the current breathing state is in a normal state, the windshield of the indoor fan of the air conditioner is controlled to maintain the current windshield; if the current breathing state is in a shallow and fast breathing state, the windshield of the indoor fan of the air conditioner is controlled to increase the third preset gear amplitude based on the current windshield; if the current breathing state is in a deep and fast breathing state, the windshield of the indoor fan of the air conditioner is controlled to increase the fourth preset gear amplitude based on the current windshield, wherein the third preset gear amplitude is smaller than the fourth preset gear amplitude. The first preset gear amplitude, the second preset gear amplitude, the third preset gear amplitude and the fourth preset gear amplitude can be pre-set according to experimental data, the first preset gear amplitude and the fourth preset gear amplitude are both two gears, and the second preset gear amplitude and the third preset gear amplitude are both one gear.

[0041] Shallow and slow breathing and deep and slow breathing usually mean that the human body is in a relatively relaxed state. At this time, lowering the fan windshield can reduce the impact of air flow on the human body and avoid affecting the relaxation state due to strong airflow interference. Different reduction ranges are set for shallow and slow breathing and deep and slow breathing. The reduction range is smaller during deep and slow breathing, because people in deep and slow breathing may be more sensitive to environmental changes. Such fine adjustment is more in line with the human body's needs for the environment during deep relaxation. Shallow and fast breathing and deep and fast breathing reflect that the human body may be in different degrees of dryness and heat. Appropriately increasing the windshield during shallow and fast breathing can bring a certain amount of air flow to help dissipate heat and relieve slight dryness and heat; increasing the windshield more significantly during deep and fast breathing can accelerate air flow, quickly take away the body's heat, and meet the body's need for coolness in a hot state. Through this differentiated adjustment, the human body's needs for wind speed at different degrees of heat sensation can be accurately matched.

[0042] In this embodiment, the step of adjusting the operating state of the air conditioner according to the current breathing state also includes: if the current breathing state is in a shallow and slow breathing state, a deep and slow breathing state, or a normal state, then the fresh air duct is closed; if the current breathing state is in a shallow and fast breathing state or a deep and fast breathing state, then the fresh air duct is opened. When the user is in a shallow and slow, deep and slow, or normal breathing state, it indicates that the indoor environment is relatively comfortable and the human body's demand for air quality changes is not urgent. At this time, closing the fresh air duct can reduce unnecessary energy loss. However, a shallow and fast or deep and fast breathing state may indicate that the indoor air is not good or that the human body's metabolism is accelerated and the demand for fresh air increases. Opening the fresh air duct can introduce fresh air in time, expel turbid air, improve air quality, and meet the human body's demand for air quality in different states.

[0043] From the above, it can be seen that the air conditioning control method based on millimeter wave radar of the present invention adopts breathing frequency and amplitude as the control parameters of air conditioning regulation, and it is relatively easy for millimeter wave radar to obtain breathing data. And the breathing frequency and amplitude can directly reflect the human body's demand for cold and heat, and air comfort. By obtaining the user's breathing frequency and amplitude in real time, different breathing states can be accurately identified, so as to confirm the breathing state in real time, and then realize the real-time dynamic adjustment of the air conditioning operation state, and improve the accuracy and reliability of monitoring.
