[0047] Figure 3 It is a structural schematic diagram of the air conditioner provided by the present invention. DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Figure 1 FIG. 1 is a flow chart of the air conditioner sleep assistance control method provided by the present invention. Figure 1 As shown, the air-conditioning auxiliary sleep control method provided by the embodiment of the present invention includes: step 101, obtaining current scene information based on human body posture information fed back by the radar module.

[0050] It should be noted that the execution subject of the auxiliary sleep control method of the air conditioner provided in the embodiment of the present invention is the auxiliary sleep control device of the air conditioner.

[0051] The application scenario of the air-conditioning auxiliary sleep control method provided by the embodiment of the present invention is that after the user activates the default working mode of the air-conditioning system (such as cooling mode, heating mode, etc.), the scene information fed back in real time by the radar module is used to determine the individual type in the space where the air-conditioning is located, and based on the fed-back human heart rate information, the sleeping state of each individual user in the room is monitored, and the air outlet temperature of the air-conditioning is adaptively adjusted based on the principle of caring for vulnerable groups.

[0052] The radar module periodically collects heart rate information of all individuals in the room at a specified time interval, and sends the heart rate information to the auxiliary sleep control device of the air conditioner. The embodiment of the present invention does not specifically limit the working cycle of the radar module.

[0053] Optionally, the radar module can perform collection operations in a default working cycle.

[0054] Optionally, the user can issue a cycle change instruction so that the radar module accepts and responds to the instruction and changes the working cycle to the cycle indicated by the instruction to perform collection operations.

[0055] It should be noted that before step 101, the user needs to send an activation instruction through a transmission medium to activate the working mode of the air conditioner, so that the indoor unit of the air conditioner runs at the default wind speed of the mode and the outdoor unit runs at the default frequency of the mode.

[0056] Optionally, the user may transmit an activation instruction through the control device by wireless communication between the control device and the air conditioner, so that the air conditioning system initializes the working mode.

[0057] Optionally, the user may issue an activation command through voice interaction, and the air conditioner receives the activation command and initializes the working mode after performing voice recognition.

[0058] Specifically, in step 101, the auxiliary sleep control device of the air conditioner must first receive the human posture information fed back by the radar module, perform contour recognition and feature extraction, and use the body features recognized for each individual in the room and the features of the currently performed actions as the current scene information.

[0059] Among them, physical characteristics can characterize the body shape and stature of an individual, and physical characteristics are used to distinguish whether an individual is a child or an adult.

[0060] Motion features can characterize the current posture of an individual, and motion features are used to distinguish whether an individual is in a sleeping state.

[0061] The embodiment of the present invention does not specifically limit the type and quantity of radar sensing devices in the radar module.

[0062] Exemplarily, the radar module may include a laser radar, an infrared sensor, etc.

[0063] Optionally, since the horizontal detection range of the millimeter-wave radar can reach ±75°, the vertical detection range can reach ±40°, the detection distance can reach 8 meters, the distance output accuracy can reach 0.1 meters, the angle output accuracy can reach 1°, and it does not involve privacy issues, is not affected by light, and its response speed is also fast. Therefore, the auxiliary sleep control device of the air conditioner uses the heart rate information collected by the millimeter-wave radar in real time as the current heart rate of the individual user.

[0064] Exemplarily, the radar module may include multiple sensor elements such as millimeter wave radar, lidar, infrared sensor, etc. The air conditioning and dehumidification control device uses the heart rate data collected by each sensor element to add and average the heart rate data to represent the current heart rate information.

[0065] Step 102: When it is determined that the current scene information shows that the individuals present in the room include at least one first target individual, and any first target individual is lying flat, a first heart rate change curve of each first target individual is obtained based on the heart rate information of each individual monitored by the radar module.

[0066] It should be noted that the first target individual refers to an individual whose physical characteristics are consistent with those of infants and young children.

[0067] Specifically, in step 102, the auxiliary sleep control device of the air conditioner analyzes the body shape characteristics and movement characteristics of each individual in the current scene information. If the analysis result is that there are one or more first target individuals in a lying state, it means that there are infants and young children in the current room who have a tendency to sleep, then the heart rate monitoring function of the radar module is activated. When the air conditioner is running in the activated working mode, the auxiliary sleep control device of the air conditioner receives the heart rate information collected by the radar module for each individual in the room in real time, and extracts the real-time heart rate information and collection time of each first target individual to construct a first heart rate change curve corresponding to the first target individual.

[0068] If the analysis result shows that all individuals in the space, including all the first target individuals, are not in a lying position, it means that no user in the room has a tendency to sleep. The air conditioner maintains its current working mode and uses the heart rate monitoring function of the radar module to determine whether each individual in the space is within the normal heart rate range. If not, a warning will be issued.

[0069] Step 103: When it is determined that any first heart rate variation curve meets the first state, control the air conditioner to switch to the sleep mode.

[0070] Among them, the first state is that the heart rate information is in a stage downward trend in the current monitoring period, and the decrease in the first time period is greater than or equal to the first preset threshold, the decrease in the second time period is greater than or equal to the second preset threshold, and the first preset threshold is greater than the second preset threshold.

[0071] It should be noted that heart rate refers to the number of heartbeats per minute. The heart rate of a normal person in a quiet state is generally 60-100 beats / minute. After activities, anger, excitement, fever, drinking coffee, strong tea and other factors will cause the heart rate to increase. When a person is sleeping, the heart rate will also change to a certain extent. In light sleep, it is about 64 to 84 beats per minute, and in deep sleep, it is only about 45 to 50 beats per minute.

[0072] The first state refers to the heart rate information collected by the radar module in multiple continuous working cycles in the current monitoring cycle, which decreases in stages with the increase of collection time, that is, gradually from light sleep to deep sleep. The decrease in heart rate information in light sleep still has a certain volatility, but the heart rate in deep sleep is relatively flat.

[0073] Therefore, it is necessary to set the first preset threshold and the second preset threshold regarding the heart rate drop in advance according to the heart rate variation characteristics of light sleep and deep sleep.

[0074] Among them, the first preset threshold is greater than the second preset threshold, indicating that in the first time period of the current monitoring cycle, the heart rate decrease is greater than or equal to the first preset threshold, indicating that the individual has entered the initial stage of light sleep, and as time goes by, the heart rate in the second time period tends to be stable, that is, the decrease is greater than or equal to the second preset threshold, indicating that the individual has entered the final stage of deep sleep. The embodiment of the present invention does not specifically limit the values ​​of the first preset threshold and the second preset threshold.

[0075] Exemplarily, the first preset threshold may be set to 20 times, and the second preset threshold may be set to 5 times, so as to avoid misjudgment caused by a sudden disease outbreak corresponding to a sudden drop in the user's individual heart rate.

[0076] Specifically, in step 103, the auxiliary sleep control device of the air conditioner analyzes the first heart rate change curves of all the first target individuals. When it is determined that there is at least one first heart rate change curve whose change trend conforms to the first state, that is, there is at least one infant in the current indoor space who is in a sleeping state, the air conditioner is controlled to switch from the current working mode to the sleep mode to operate.

[0077] Step 104: Based on the first current heart rate, the first inflection point, and the second inflection point in the first heart rate change curve, control the air conditioner to adjust the air outlet temperature in the sleep mode.

[0078] The first inflection point is determined based on the heart rate information in the first time period, and the second inflection point is determined based on the heart rate information in the second time period.

[0079] It should be noted that the first inflection point is an inflection point determined by a curve corresponding to the first time period in the first heart rate change curve that conforms to the first state, so as to represent the critical heart rate value when the infant enters light sleep.

[0080] The second inflection point is an inflection point determined by a curve corresponding to the second time period in the first heart rate change curve that conforms to the first state, so as to represent the critical heart rate value when the infant enters deep sleep.

[0081] Specifically, in step 104, the auxiliary sleep control device of the air conditioner extracts the first current heart rate, the first inflection point and the second inflection point in the current monitoring cycle from the first heart rate change curve that conforms to the first state, and determines the degree of sleep state of the individual infant, so as to control the air conditioner to adaptively adjust the air outlet temperature in the sleep mode.

[0082] The number of the first heart rate change curves that conform to the first state may be one or more, that is, there may be one or more infants and young children in a sleeping state in the current indoor space.

[0083] Optionally, when the number of first heart rate change curves that conform to the first state is only one, the first current heart rate, the first inflection point and the second inflection point are extracted from the first heart rate change curve to determine the degree of sleep state of the individual infant or child, so as to adjust the operating frequency of the outdoor unit so that the air outlet temperature of the indoor unit can be maintained in a range suitable for the sleep state.

[0084] Optionally, when there are multiple first heart rate change curves that conform to the first state, the respective first current heart rates are extracted from the multiple different first heart rate change curves corresponding to the multiple first target individuals, and the weighted average is used as the current heart rate of the infant group, and the maximum value is selected from the first inflection points of the multiple different first heart rate change curves as the first inflection point of the group. Similarly, the second inflection point of the group is integrated, and the current heart rate, first inflection point and second inflection point of the group are used to judge the average level of the sleep state of multiple infants and young children, so as to adjust the operating frequency of the outdoor unit so that the air outlet temperature of the indoor unit can be maintained in a range suitable for the sleep state.

[0085] The embodiment of the present invention depicts the current scene information based on the human posture information fed back by the radar module, and monitors the change trend of the heart rate information of the first target individual through the current scene information, and decides to adjust the air outlet temperature through the first current heart rate, the first inflection point and the second inflection point in the first heart rate change curve. It realizes the identification of the user types included in the group and the corresponding action intentions according to the actual scene. When it is determined that there are infants and young children in the group, the principle of giving priority to the vulnerable group is adopted, and the air outlet temperature in the sleep mode is adjusted according to the changes in the heart rate of infants and young children, thereby improving the control accuracy of the room temperature and enhancing the user experience.

[0086] Based on any of the above embodiments, based on the first current heart rate, the first inflection point and the second inflection point in the first heart rate change curve, the air conditioner is controlled to adjust the air outlet temperature in the sleep mode, including: determining the first sleep coefficient based on the first current heart rate, the heart rate value corresponding to the first inflection point and the heart rate value corresponding to the second inflection point.

[0087] Specifically, in step 104, the auxiliary sleep control device of the air conditioner extracts the heart rate value P1 corresponding to the first inflection point from the two curves corresponding to the first time period and the second time period in the first heart rate change curve. light , and the heart rate value P1 corresponding to the second inflection point deep Then the first current heart rate P1 and the heart rate value P1 corresponding to the first inflection point are light The heart rate value P1 corresponding to the second inflection point deep , use the corresponding mathematical model to calculate and obtain the first sleep coefficient.

[0088] The embodiment of the present invention does not specifically limit the mathematical model for calculating the first sleep coefficient.

[0089] Preferably, the mathematical model of the first sleep coefficient is the ratio of the sleep state corresponding to the first current heart rate to deep sleep or light sleep, and its calculation formula is as follows:

[0090]

[0091] Among them, C1 is the first sleep coefficient, and the value range of C1 is [0,1]. It can be seen that if C1 is 0, it means that the sleep state corresponding to the first current heart rate is in deep sleep, and the closer to 0, the closer to deep sleep; if C1 is 1, it means that the sleep state corresponding to the first current heart rate is in light sleep, and the closer to 1, the closer to light sleep.

[0092] Based on the first sleep coefficient and the outdoor temperature, a first target air outlet temperature is determined so that the air conditioner can adjust the air outlet temperature in the sleep mode to the first target air outlet temperature.

[0093] Specifically, the auxiliary sleep control device of the air conditioner uses the outdoor temperature collected in real time by a temperature sensor installed outdoors as a benchmark, and makes adaptive adjustments based on the sleep level indicated by the first sleep coefficient to obtain the first target air outlet temperature, and sends control instructions to both the indoor and outdoor units of the air conditioner.

[0094] The indoor unit and the outdoor unit receive and respond to the control instructions, drive each component to operate, and under the joint action of the two, the initial air outlet temperature in the sleep mode is adjusted to the first target air outlet temperature and continues to operate.

[0095] The embodiment of the present invention does not specifically limit the calculation method of the first target air outlet temperature.

[0096] Optionally, the first target air outlet temperature T1 is calculated as follows:

[0097] T1=t1-(a+b*C1)

[0098] Wherein, t1 is the outdoor temperature, a and b are both temperature adjustment coefficients, and the embodiment of the present invention does not specifically limit the values ​​of a and b.

[0099] Exemplarily, a can be set to 3, and b can be set to 2, that is, the first target air outlet temperature can be reduced by 3°C-5°C with the outdoor temperature as a reference.

[0100] In the sleep mode corresponding to infants, if the infant is in deep sleep (C1 is 0), the outlet temperature is adjusted to 3°C lower than the outdoor temperature. When the infant is in light sleep (C1 is 1), the outlet temperature is adjusted to 5°C lower than the outdoor temperature.

[0101] The embodiment of the present invention performs corresponding calculations based on the heart rate value corresponding to the first inflection point and the heart rate value corresponding to the second inflection point in combination with the first current heart rate to obtain a first sleep coefficient, obtains a first target air outlet temperature through the first sleep coefficient in combination with the outdoor temperature, and adjusts the air outlet temperature to the first target air outlet temperature under the joint action of the indoor unit and the outdoor unit. This achieves quantitative adjustment of the air outlet temperature in the infant's sleep mode according to the infant's actual heart rate in the sleep state when there are infants and young children indoors, thereby improving the control accuracy and efficiency of the air outlet temperature, while also taking into account energy efficiency savings and optimizing user experience.

[0102] On the basis of any of the above embodiments, after obtaining the current scene information based on the human posture information fed back by the radar module, it also includes: when it is determined that the current scene information is that all individuals in the room are second target individuals, and any second target individual is lying flat, based on the heart rate information of each individual monitored by the radar module, obtaining a second heart rate change curve for each individual.

[0103] It should be noted that the second target individual refers to an individual whose physical characteristics conform to those of an adult.

[0104] Specifically, after step 101, the auxiliary sleep control device of the air conditioner analyzes the body shape characteristics and movement characteristics of each individual in the current scene information. If the analysis result is that all individuals are second target individuals and at least one second target individual is in a lying state, it means that there are no infants and young children in the current room and at least one adult individual has a tendency to sleep. Then, the heart rate monitoring function of the radar module is activated. When the air conditioner is running in the activated working mode, the auxiliary sleep control device of the air conditioner receives the heart rate information collected by the radar module for each individual in the room in real time, and constructs a second heart rate change curve corresponding to the second target individual according to the real-time heart rate information and collection time of each second target individual.

[0105] If the analysis result shows that all individuals in the space are the second target individuals and are not lying flat, it means that there are no infants or young children in the room and no adult individuals have a tendency to sleep. The air conditioner maintains its current working mode and uses the heart rate monitoring function of the radar module to determine whether each individual in the space is within the normal heart rate range. If not, a warning will be issued.

[0106] When it is determined that any second heart rate variation curve conforms to the first state, the air conditioner is controlled to switch to the sleep mode.

[0107] Among them, the first state is that the heart rate information is in a stage downward trend in the current monitoring period, and the decrease in the first time period is greater than or equal to the first preset threshold, the decrease in the second time period is greater than or equal to the second preset threshold, and the first preset threshold is greater than the second preset threshold.

[0108] Specifically, the auxiliary sleep control device of the air conditioner analyzes the second heart rate change curves of all second target individuals. When it is determined that there is at least one second heart rate change curve whose change trend conforms to the first state, that is, there are no infants or young children in the current indoor space, and there is at least one adult in a sleeping state, the air conditioner is controlled to switch from the current working mode to the sleep mode to operate.

[0109] Based on the second current heart rate, the third inflection point, and the fourth inflection point in the second heart rate change curve, controlling the air conditioner to adjust the air outlet temperature in the sleep mode;

[0110] The third inflection point is determined based on the heart rate information in the first time period, and the fourth inflection point is determined based on the heart rate information in the second time period.

[0111] It should be noted that the third inflection point is an inflection point determined by a curve corresponding to the first time period in the second heart rate change curve that conforms to the first state, so as to represent the critical heart rate value when an adult enters light sleep.

[0112] The fourth inflection point is an inflection point determined by a curve section corresponding to the second time period in the second heart rate change curve that conforms to the first state, to represent the critical heart rate value when an adult enters deep sleep.

[0113] Specifically, the auxiliary sleep control device of the air conditioner extracts the second current heart rate, the third inflection point and the fourth inflection point in the current monitoring cycle from the second heart rate change curve that conforms to the first state, and determines the degree of sleep state of the adult individual, so as to control the air conditioner to adaptively adjust the air outlet temperature in the sleep mode.

[0114] The number of the second heart rate change curves that conform to the first state may be one or more, that is, when there are no infants or young children in the current indoor space, there are one or more adult individuals in a sleeping state.

[0115] Optionally, when the number of second heart rate change curves that conform to the first state is only one, the second current heart rate, the third inflection point and the fourth inflection point are extracted from the second heart rate change curve to determine the degree of sleep state of the adult individual, so as to adjust the operating frequency of the outdoor unit so that the air outlet temperature of the indoor unit can be maintained in a range suitable for the sleep state.

[0116] Optionally, in the case that there are multiple second heart rate change curves that conform to the first state, the respective second current heart rates are extracted from the multiple different second heart rate change curves corresponding to the multiple second target individuals, and the weighted average is taken as the current heart rate of the adult group, and the maximum value is selected from the third inflection points of the multiple different second heart rate change curves as the third inflection point of the group. Similarly, the fourth inflection point of the group is integrated, and the current heart rate, third inflection point and fourth inflection point of the group are used to judge the average level of the sleep status of multiple adult individuals, so as to adjust the operating frequency of the outdoor unit so that the air outlet temperature of the indoor unit can be maintained in a range suitable for the sleep state.

[0117] The embodiment of the present invention depicts the current scene information based on the human posture information fed back by the radar module, and monitors the change trend of the heart rate information of the second target individual through the current scene information. The second current heart rate, the third inflection point and the fourth inflection point in the acquired second heart rate change curve are used to decide to adjust the air outlet temperature. The user types and corresponding action intentions included in the group are identified according to the actual scene. When it is determined that there are no infants in the group, the air outlet temperature in the sleep mode is adjusted directly according to the heart rate changes of adults, thereby improving the control accuracy of the room temperature and enhancing the user experience.

[0118] Based on any of the above embodiments, controlling the air conditioner to adjust the air outlet temperature in the sleep mode based on the second current heart rate, the third inflection point, and the fourth inflection point in the second heart rate change curve includes:

[0119] A second sleep coefficient is determined based on the second current heart rate, the heart rate value corresponding to the third inflection point, and the heart rate value corresponding to the fourth inflection point.

[0120] Specifically, the auxiliary sleep control device of the air conditioner uses the two curves corresponding to the first period and the second period in the second heart rate change curve to extract the heart rate value corresponding to the third inflection point respectively. And the heart rate value P2 corresponding to the fourth inflection point deep Then the second current heart rate P2 and the heart rate value corresponding to the third inflection point are The heart rate value P2 corresponding to the fourth inflection point deep , use the corresponding mathematical model to calculate and obtain the second sleep coefficient.

[0121] The embodiment of the present invention does not specifically limit the mathematical model for calculating the second sleep coefficient.

[0122] Preferably, the mathematical model of the second sleep coefficient is the ratio of the sleep state corresponding to the second current heart rate to deep sleep or light sleep, and its calculation formula is as follows:

[0123]

[0124] Among them, C2 is the second sleep coefficient, and the value range of C2 is [0,1]. It can be seen that if C1 is closer to 0, the sleep state is closer to deep sleep, and the closer it is to 1, the sleep state is closer to light sleep.

[0125] Based on the second sleep coefficient and the set temperature, a second target air outlet temperature is determined so that the air conditioner can adjust the air outlet temperature in the sleep mode to the second target air outlet temperature.

[0126] The set temperature is the temperature setting value in the sleep mode.

[0127] It should be noted that the set temperature refers to the set value of the indoor temperature in the sleep mode, and its value can be the default temperature of the sleep mode, or it can be the temperature set by the user through the control device. The embodiment of the present invention does not make specific limitations on this.

[0128] Specifically, the auxiliary sleep control device of the air conditioner uses the set temperature in the pre-indicated sleep mode as a reference, performs adaptive adjustment based on the sleep degree indicated by the second sleep coefficient, obtains the second target air outlet temperature, and sends control instructions to both the indoor unit and the outdoor unit of the air conditioner.

[0129] The indoor unit and the outdoor unit receive and respond to the control instructions, drive each component to operate, and under the joint action of the two, the initial air outlet temperature in the sleep mode is adjusted to the second target air outlet temperature and continues to operate.

[0130] The embodiment of the present invention does not specifically limit the calculation method of the second target air outlet temperature.

[0131] Optionally, the second target air outlet temperature T2 is calculated as follows:

[0132] T2=t2-(a+b*C2)

[0133] Wherein, t2 is the set temperature, a and b are both temperature adjustment coefficients, and the embodiment of the present invention does not specifically limit the values ​​of a and b.

[0134] Exemplarily, a can be set to 3, and b can be set to 2, that is, the second target air outlet temperature can be reduced by 3°C-5°C with the set temperature as a reference.

[0135] In the sleep mode corresponding to adults, if the adult is in deep sleep (C2 is 0), the air outlet temperature is adjusted to 3°C lower than the set temperature. When the adult is in light sleep (C2 is 1), the air outlet temperature is adjusted to 5°C lower than the set temperature.

[0136] The embodiment of the present invention performs corresponding calculations based on the heart rate value corresponding to the third inflection point and the heart rate value corresponding to the fourth inflection point in combination with the second current heart rate to obtain a second sleep coefficient, obtains a second target air outlet temperature through the second sleep coefficient in combination with the set temperature, and adjusts the air outlet temperature to the second target air outlet temperature under the joint action of the indoor unit and the outdoor unit. This achieves quantitative adjustment of the air outlet temperature in the adult sleep mode according to the actual heart rate of the adults in the sleep state when all the individuals indoors are adults, thereby improving the control accuracy and efficiency of the air outlet temperature, while also taking into account energy efficiency and saving, and optimizing the user experience.

[0137] Based on any of the above embodiments, after controlling the air conditioner to switch to the sleep mode, it also includes: continuing to obtain a first heart rate change curve of each first target individual based on the heart rate information monitored by the radar module.

[0138] Specifically, after step 103, the auxiliary sleep control device of the air conditioner receives the heart rate information continuously monitored by the radar module on each first target individual, and uses it as the heart rate information at the next moment to update the first heart rate change curve.

[0139] When it is determined that all the first heart rate variation curves conform to the second state, the air conditioner is controlled to exit the sleep mode.

[0140] Among them, the second state is that the heart rate information is in an upward trend in the current monitoring period, and the increase is greater than or equal to the first preset threshold.

[0141] It should be noted that the second state means that in the current monitoring cycle, the heart rate information collected by the radar module in multiple consecutive working cycles increases with the increase of collection time, and the increase in the heart rate information is greater than or equal to the first preset threshold.

[0142] Specifically, the air conditioner's auxiliary sleep control device analyzes the heart rate change curves of all individuals updated in real time. If there is a first heart rate change curve among many curves, and it is determined that the change trends of all first heart rate change curves are consistent with the second state, it means that there are infants and young children in the current indoor space, and all infants and young children are in a wakeful state. Then the air conditioner is controlled to exit the infant sleep mode and operate in the original working mode.

[0143] It can be understood that if there is only a second heart rate change curve among many heart rate curves, and it is determined that the change trends of all second heart rate change curves are consistent with the second state, it means that there are no infants and young children in the current indoor space, and all existing adult individuals are in a wakeful state, then the air conditioner is controlled to exit the adult sleep mode and operate in the original working mode.

[0144] The embodiment of the present invention monitors the heart rate of the first target individual in real time based on the radar module, updates the first heart rate change curve, and when it is determined that all the first heart rate change curves conform to the second state, decides to control the air conditioner to exit the sleep mode. When there are infants and young children in the room, the awakening state analysis is carried out according to the heart rate changes of the individual infants and young children, and the working mode of the air conditioner is switched adaptively, so that all infants and young children can receive the fresh air volume in the original working mode after waking up, thereby improving the control accuracy of the room temperature and enhancing the user experience.

[0145] Based on any of the above embodiments, when it is determined that any first heart rate variation curve conforms to the first state, it also includes: generating a first display voltage signal to control the brightness emitted by the light emitting array to gradually decrease to 0 within a preset time.

[0146] It should be noted that the light array refers to a component that is fixedly arranged with at least one light emitting element in a predetermined arrangement. For example, the light array can be a light strip around the air outlet of the indoor unit to achieve a light perception change in the sleep mode of the indoor unit to assist sleep.

[0147] Specifically, in step 103, when it is determined that there is a first target individual in the space and the changing trend of its first heart rate change curve conforms to the first state, the air conditioner is controlled to switch from the current working mode to the infant sleep mode, and a first display voltage signal is generated and sent to the light-emitting array.

[0148] The light emitting array receives and responds to the first display voltage signal, gradually reducing its own brightness within a preset time period until it is turned off (ie, the brightness is 0).

[0149] The embodiment of the present invention does not specifically limit the value of the preset duration.

[0150] Exemplarily, based on historical experience data, the preset duration is set to 10 minutes.

[0151] It can be understood that when it is determined that all individuals in the space are second target individuals and the changing trend of the second heart rate change curve of any second target individual conforms to the first state, while controlling the air conditioner to switch from the current working mode to the adult sleep mode, the first voltage signal can also be used to gradually extinguish the light array, and the initial self-brightness before extinguishing can be higher than that of the infant sleep mode.

[0152] The embodiment of the present invention controls the light array to perform a light perception from bright to extinguished in the sleep mode while deciding to control the air conditioner to start the sleep mode through the first display voltage signal. This achieves that when the working mode of the air conditioner is switched to the sleep mode, the light perception gradually fades, thereby helping the user maintain a high sleep quality and improving the user experience.

[0153] Based on any of the above embodiments, when it is determined that all first heart rate change curves conform to the second state, it also includes: generating a second display voltage signal to control the brightness emitted by the light emitting array to gradually increase from 0 within a preset time.

[0154] Specifically, when it is determined that there is a first target individual in the space and the change trends of the first heart rate change curves of all the first target individuals conform to the second state, the air conditioner is controlled to switch from the infant sleep mode to the original working mode, and a second display voltage signal is generated and sent to the light-emitting array.

[0155] The light emitting array receives and responds to the second display voltage signal, and gradually increases its own brightness from off (ie, brightness is 0) to bright within a preset time period.

[0156] It can be understood that when it is determined that all individuals in the space are second target individuals and the changing trends of the second heart rate change curves of all second target individuals conform to the second state, while controlling the air conditioner to switch from the adult sleep mode to the original working mode, the second voltage signal can also be used to gradually brighten the light-emitting array, and the final brightness after brightening can be higher than that of the infant sleep mode.

[0157] The embodiment of the present invention controls the light array to change from off to bright light sense along with the wake-up mode through the second display voltage signal while making a decision to control the air conditioner to exit the sleep mode. This realizes that when the sleep mode of the air conditioner is switched to the original working mode, the light sense gradually becomes stronger, thereby helping the user maintain a high level of wakefulness and improving the user experience.

[0158] Based on any of the above embodiments, after the heart rate information is monitored by the radar module, it also includes: when the heart rate information exceeds a preset healthy range, an alarm and distress message is sent to the relevant remote terminal user through the application gateway.

[0159] The healthy range refers to the interval range determined in advance based on the upper and lower limits of the normal heart rate of the human body. For example, the healthy range can be [60, 150).

[0160] Specifically, while the radar module is monitoring the heart rate information of each individual in real time, the auxiliary sleep control device of the air conditioner compares the current heart rate information with the healthy range, and the results are divided into two types: comparison success and comparison failure.

[0161] Among them, a successful comparison means that the current heart rate information of all individuals in the space is within a healthy range, which means that all individuals are normal and healthy. Then, we can continue to judge the sleep level of each individual based on their heart rate information, and use this as the basis for adjusting the air outlet temperature in sleep mode.

[0162] Comparison failure means that the current heart rate information of any individual in the space is less than the lower limit of the healthy range or greater than the upper limit of the healthy range, which means that there is an individual in an abnormal and critical situation. In this case, it is necessary to use the application gateway to send an alarm and distress message to the user of the registered remote terminal.

[0163] The embodiment of the present invention does not specifically limit the process of performing remote alarm.

[0164] Optionally, according to the sub-interval in which the current heart rate information that exceeds the healthy range is located, the alarm information corresponding to the sub-interval is determined, and the alarm information is sent to the remote terminal through the gateway.

[0165] For example, the interval range that is smaller than the lower limit of the healthy range can be divided in advance to obtain at least two sub-intervals, namely [0, 40) and [40, 60) and at the same time, the interval range that is larger than the upper limit of the healthy range can be divided to obtain at least two sub-intervals, namely [150, 160) and [160, 180) as well.

[0166] If the heart rate information is between [0, 40) for more than two consecutive times, the individual is considered to have sinus bradycardia, and if the heart rate information is between [160, 180) for more than two consecutive times, the individual is considered to have sinus tachycardia. The alarm information for the above two situations includes but is not limited to text information, sound and light information, etc., to remind the family members of the user of the remote terminal that the situation is urgent and trigger a one-click call for help.

[0167] If the heart rate information is between [40, 60) for more than two consecutive times, it is determined that the individual's heart rate is low, and if the heart rate information is between [150, 160) for more than two consecutive times, it is determined that the individual's heart rate is high. The alarm information for the above two situations includes but is not limited to text information, sound and light information, etc., to remind the user of the remote terminal that the family members are at risk of disease and to remind them to seek medical examination.

[0168] When monitoring the heart rate of an individual indoors, the embodiment of the present invention sends an alarm and help message to the relevant remote terminal user through a preset health range decision. It can determine whether the individual indoors has a sudden loss of consciousness with symptoms of abnormal heart rate based on the heart rate of the individual, and send an alarm and help message to the relevant mobile terminal user through the application gateway so that timely rescue can be provided.

[0169] Figure 2 FIG. 1 is a schematic diagram of the structure of the auxiliary sleep control device for the air conditioner provided by the present invention. Figure 2 As shown, the auxiliary sleep control device of the air conditioner provided in the embodiment of the present invention includes a scene perception module 210, a heart rate monitoring module 220, a mode switching module 230 and a first control module 240, wherein:

[0170] The scene perception module 210 is used to obtain current scene information based on the human posture information fed back by the radar module.

[0171] The heart rate monitoring module 220 is used to obtain a first heart rate change curve of each first target individual based on the heart rate information of each individual monitored by the radar module when it is determined that the current scene information shows that the individuals existing in the room include at least one first target individual and any first target individual is lying flat.

[0172] The mode switching module 230 is used to control the air conditioner to switch to the sleep mode when it is determined that any first heart rate variation curve meets the first state.

[0173] The first control module 240 is used to control the air conditioner to adjust the air outlet temperature in the sleep mode based on the first current heart rate, the first inflection point and the second inflection point in the first heart rate change curve.

[0174] The first state is that the heart rate information is in a phased downward trend in the current monitoring period, and the decrease in the first period is greater than or equal to the first preset threshold, the decrease in the second period is greater than or equal to the second preset threshold, and the first preset threshold is greater than the second preset threshold. The first inflection point is determined based on the heart rate information in the first period, and the second inflection point is determined based on the heart rate information in the second period.

[0175] Specifically, the scene perception module 210, the heart rate monitoring module 220, the mode switching module 230 and the first control module 240 are electrically connected in sequence.

[0176] The scene perception module 210 first receives the human posture information fed back by the radar module, performs contour recognition and feature extraction, and uses the recognized shape features of each individual in the room and the features of the currently executed action as the current scene information.

[0177] The heart rate monitoring module 220 analyzes the body shape and movement characteristics of each individual in the current scene information. If the analysis result shows that there are one or more first target individuals in a lying state, it means that there are infants and young children in the room who have a tendency to sleep. Then the heart rate monitoring function of the radar module is activated. When the air conditioner is running in the activated working mode, the auxiliary sleep control device of the air conditioner receives the heart rate information collected by the radar module for each individual in the room in real time, and extracts the real-time heart rate information and collection time of each first target individual to construct a first heart rate change curve corresponding to the first target individual.

[0178] If the analysis result shows that all individuals in the space, including all the first target individuals, are not in a lying position, it means that no user in the room has a tendency to sleep. The air conditioner maintains its current working mode and uses the heart rate monitoring function of the radar module to determine whether each individual in the space is within the normal heart rate range. If not, a warning will be issued.

[0179] The mode switching module 230 analyzes the first heart rate change curves of all first target individuals. When it is determined that there is at least one first heart rate change curve whose change trend conforms to the first state, that is, there is at least one infant in the current indoor space who is sleeping, the air conditioner is controlled to switch from the current working mode to the sleeping mode.

[0180] The first control module 240 extracts the first current heart rate, the first inflection point and the second inflection point in the current monitoring period from the first heart rate change curve that conforms to the first state, and determines the degree of sleep state of the individual infant or child, so as to control the air conditioner to adaptively adjust the air outlet temperature in the sleep mode.

[0183] The first control unit is used to determine a first target air outlet temperature based on a first sleep coefficient and an outdoor temperature, so that the air conditioner can adjust the air outlet temperature in the sleep mode to the first target air outlet temperature.

[0184] Optionally, the device includes a heart rate monitoring module 220 and a mode switching module 230, and also includes a second control module, wherein:

[0185] The heart rate monitoring module 220 is also used to obtain the second heart rate change curve of each individual based on the heart rate information of each individual monitored by the radar module when it is determined that the current scene information is that all individuals in the room are second target individuals and any second target individual is lying flat.

[0186] The mode switching module 230 is further configured to control the air conditioner to switch to the sleep mode when it is determined that any second heart rate variation curve conforms to the first state.

[0187] The second control module is used to control the air conditioner to adjust the air outlet temperature in the sleep mode based on the second current heart rate, the third inflection point and the fourth inflection point in the second heart rate change curve.

[0188] Among them, the first state is that the heart rate information is in a stage downward trend in the current monitoring period, and the decrease in the first time period is greater than or equal to the first preset threshold, the decrease in the second time period is greater than or equal to the second preset threshold, and the first preset threshold is greater than the second preset threshold; the third inflection point is determined based on the heart rate information in the first time period, and the fourth inflection point is determined based on the heart rate information in the second time period.

[0189] Optionally, the second control module includes a second sleep characterization unit and a second control unit, wherein:

[0190] The second sleep characterization unit is used to determine a second sleep coefficient based on the second current heart rate, the heart rate value corresponding to the third inflection point, and the heart rate value corresponding to the fourth inflection point.

[0191] The second control unit is used to determine a second target air outlet temperature based on a second sleep coefficient and a set temperature, so that the air conditioner adjusts the air outlet temperature in the sleep mode to the second target air outlet temperature.

[0192] The set temperature is the temperature setting value in the sleep mode.

[0193] Optionally, the auxiliary sleep control device of the air conditioner further includes a curve updating module and a third control module, wherein:

[0194] The curve updating module is used to continue to obtain the first heart rate change curve of each first target individual based on the heart rate information monitored by the radar module.

[0195] The third control module is used to control the air conditioner to exit the sleep mode when it is determined that all the first heart rate change curves conform to the second state.

[0196] Among them, the second state is that the heart rate information is in an upward trend in the current monitoring period, and the increase is greater than or equal to the first preset threshold.

[0197] Optionally, the first control module 340 further includes a first light control unit, wherein:

[0198] The first light control unit is used to generate a first display voltage signal to control the brightness of the light emitting array to gradually decrease to 0 within a preset time period.

[0199] Optionally, the third control module further includes a second lighting control unit, wherein:

[0200] The second light control unit is used to generate a second display voltage signal to control the brightness of the light emitting array to gradually increase from 0 within a preset time period.

[0201] Optionally, the device further comprises a remote alarm module, wherein:

[0202] The remote alarm module is used to send alarm and distress information to relevant remote terminal users through the application gateway when the heart rate information exceeds the preset healthy range.

[0203] The auxiliary sleep control device for an air conditioner provided in an embodiment of the present invention is used to execute the auxiliary sleep control method for the air conditioner mentioned above in the present invention. Its implementation method is consistent with the implementation method of the auxiliary sleep control method for the air conditioner provided by the present invention, and can achieve the same beneficial effects, which will not be repeated here.

[0204] The embodiment of the present invention depicts the current scene information based on the human posture information fed back by the radar module, and monitors the change trend of the heart rate information of the first target individual through the current scene information, and decides to adjust the air outlet temperature through the first current heart rate, the first inflection point and the second inflection point in the first heart rate change curve. It realizes the identification of the user types included in the group and the corresponding action intentions according to the actual scene. When it is determined that there are infants and young children in the group, the principle of giving priority to the vulnerable group is adopted, and the air outlet temperature in the sleep mode is adjusted according to the changes in the heart rate of infants and young children, thereby improving the control accuracy of the room temperature and enhancing the user experience.

[0208] It is also necessary to set one or more radar modules 312 on the surface of the indoor unit 310 at the non-air outlet to collect the heart rate of individual users in the room in real time for real-time monitoring, and feed it back to the control processor 311 for logical judgment of wind speed control.

[0209] Preferably, the radar module 312 is composed of a millimeter wave radar, and a strip-shaped light array is arranged around the air outlet of the indoor unit 310.
