Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to a radar-based air conditioning swing control method, device, and air conditioner. Background Technology

[0002] With the general improvement of people's living standards, air conditioners of various types and functions have entered all walks of life and ordinary households, creating a comfortable temperature and humidity environment for people. Existing technologies are also beginning to apply radar sensing systems to the air conditioning field, making air conditioners more intelligent and improving people's quality of life.

[0003] Existing air conditioners can monitor users' sleep status in a room in real time using radar, such as location and heart rate, and make corresponding intelligent adjustments based on the detected data. However, because users in a space are mobile and have different needs, existing technology cannot accurately determine the actual state and needs of users at different times. It can only adjust the air conditioner's state based on perceived environmental information. For example, when a user gets up at night, the radar can detect that the user has left sleep, so it will increase the current operating mode, which will make the user feel uncomfortable. Therefore, the accuracy of existing air conditioners based on radar perception for regulation is poor, resulting in low user comfort. Summary of the Invention

[0004] This invention provides a radar-based air conditioning swing control method, device, and air conditioner to solve the problem of poor control accuracy caused by the simple swing control logic in the prior art.

[0005] This invention provides a radar-based air conditioning swing control method, comprising:

[0006] Based on the contour information of each user individual monitored by the radar module, the behavioral status information of each user individual is obtained.

[0007] If the target user's behavior state is determined to be lying down, the indoor light intensity collected by the light-sensing module in the space where the air conditioner is located is obtained; wherein, the target user is any one of the users currently present in the room;

[0008] When the indoor light intensity is determined to be greater than the first preset threshold, the first sway blade assembly is controlled to point towards the lying position of the target user to provide fixed air supply, and the second sway blade assembly is controlled to swing freely to perform air sweeping.

[0009] The first swaying blade assembly is a swaying blade assembly whose swaying blade arrangement direction is perpendicular to the lying direction of the target user individual; the second swaying blade assembly is a swaying blade assembly other than the first swaying blade assembly; the swaying blade assembly includes a horizontal swaying blade assembly and a vertical swaying blade assembly.

[0010] According to a radar-based air conditioning swing control method provided by the present invention, when the indoor light intensity is determined to be greater than a first preset threshold, the method controls a first swing blade assembly to point towards the lying position of the target user individual for fixed air supply, and controls a second swing blade assembly to swing freely for sweeping air supply, comprising:

[0011] If the difference between the first endpoint position and the second endpoint position of the target user individual in the air conditioning coordinate system in the Y-axis direction is less than or equal to the second preset threshold, the first swing blade assembly is set as a horizontal swing blade assembly and the second swing blade assembly is set as a vertical swing blade assembly.

[0012] Based on the first endpoint position and the second endpoint position, a first execution angle is determined for pointing to the supine position of the target user individual;

[0013] During the process of controlling the vertical sway blade assembly to swing left and right, the horizontal sway blade assembly stops swinging up and down when it is determined that the horizontal sway blade assembly has moved to the first execution angle.

[0014] The air conditioning coordinate system is established with the horizontal line where the indoor unit of the air conditioner is located in the horizontal plane as the X-axis and the horizontal line perpendicular to the indoor unit of the air conditioner as the Y-axis; the first endpoint position and the second endpoint position are the position coordinates of the outline of the target user individual at the left and right boundaries in the horizontal direction, respectively.

[0015] According to a radar-based air conditioning swing control method provided by the present invention, when the indoor light intensity is determined to be greater than a first preset threshold, the method controls a first swing blade assembly to point towards the lying position of the target user individual for fixed air supply, and controls a second swing blade assembly to swing freely for sweeping air supply, comprising:

[0016] If the difference between the third endpoint position and the fourth endpoint position of the target user individual in the air conditioning coordinate system in the X-axis direction is less than or equal to a third preset threshold, the first swing blade assembly is set as a vertical swing blade assembly and the second swing blade assembly is set as a horizontal swing blade assembly.

[0017] Based on the third endpoint position and the fourth endpoint position, a second execution angle is determined for pointing to the supine position of the target user individual;

[0018] During the process of controlling the horizontal sway blade assembly to swing up and down, the vertical sway blade assembly stops swinging left and right when it is determined that the vertical sway blade assembly has moved to the second execution angle.

[0019] The air conditioning coordinate system is established with the horizontal line where the indoor unit of the air conditioner is located in the horizontal plane as the X-axis and the horizontal line perpendicular to the indoor unit of the air conditioner as the Y-axis; the third endpoint position and the fourth endpoint position are the position coordinates of the outline of the target user individual at the upper and lower boundaries in the vertical direction, respectively.

[0020] According to a radar-based air conditioning swing control method provided by the present invention, the method for obtaining behavioral state information of each user based on the contour information of each individual monitored by the radar module includes:

[0021] When it is determined from the radar module that at least one user exists indoors, the first contour length and the second contour length are determined based on the contour information of each user.

[0022] If the length of the first contour is greater than the length of the second contour, then the behavior state information is set to the vertical state.

[0023] If the length of the first contour is less than or equal to the length of the second contour, then the behavior state information is set to the lying-flat state;

[0024] Wherein, the first contour length is the length information of the user's individual contour in the Z-axis direction of the air conditioning coordinate system; the second contour length is the length information of the user's individual contour in the X-axis direction of the air conditioning coordinate system.

[0025] According to a radar-based air conditioning swing control method provided by the present invention, before obtaining the behavioral state information of each user individual based on the contour information of each user individual monitored by the radar module, the method further includes:

[0026] When the radar module determines that there are no individual users indoors, the duration of the indoor unoccupied state is calculated.

[0027] When the duration of the indoor unoccupied state reaches the target level, the indoor air conditioner unit is controlled to operate in the energy-saving mode corresponding to the target level until the maximum level is reached and the indoor air conditioner unit is turned off.

[0028] The target levels include multiple levels with increasing durations for indoor unoccupied conditions; the operating power of each level decreases in the corresponding energy-saving mode.

[0029] According to a radar-based air conditioning swing control method provided by the present invention, after acquiring the indoor light intensity collected by the light sensing module of the space where the air conditioner is located, the method further includes:

[0030] When the indoor light intensity is determined to be less than or equal to the first preset threshold, the sleep mode is activated, and the horizontal sway blade assembly is controlled to swing up and down, while the vertical sway blade assembly is controlled to swing left and right.

[0031] The present invention also provides a radar-based air conditioning swing control device, comprising:

[0032] The behavior analysis module is used to obtain the behavior status information of each user based on the contour information of each user monitored by the radar module.

[0033] The light monitoring module is used to acquire the indoor light intensity collected by the light sensing module in the space where the air conditioner is located when the behavior state information of the target user individual is determined to be lying down; wherein, the target user individual is any one of the users currently included in the room;

[0034] The control module is used to control the first swaying blade assembly to point to the lying position of the target user individual for fixed air supply when the indoor light sensitivity is determined to be greater than the first preset threshold, and to control the second swaying blade assembly to swing freely for sweeping air.

[0035] Wherein, the first swaying blade assembly is a swaying blade assembly in which the swaying blade arrangement direction is perpendicular to the lying direction of the target user individual; the second swaying blade assembly is a swaying blade assembly other than the first swaying blade assembly; the swaying blade assembly includes a horizontal swaying blade assembly and a vertical swaying blade assembly; the target user individual is any one of the user individuals currently included in the room.

[0036] The present invention also provides an air conditioner, including an indoor unit and an outdoor unit. The indoor unit is provided with a control processor, a light sensor module, and a radar module. The light sensor module is integrated into the display panel of the indoor unit. The radar module is disposed on the surface of the housing of the indoor unit. The air conditioner also includes a memory and a program or instructions stored in the memory and executable on the control processor. When the program or instructions are executed by the control processor, they perform the radar-based air conditioner swing control method as described above.

[0037] The radar module includes a millimeter-wave radar.

[0040] The radar-based air conditioning swing control method, device, and air conditioner provided by this invention, when the radar module detects that at least one user is lying down, and the light sensor module collects the current indoor light intensity, and the objective environment is determined to be daytime through threshold comparison using the indoor light intensity, decides to adjust the swing mode of the indoor unit. This means that the swing blade assembly with its blades arranged perpendicular to the lying direction of the user directs airflow towards that user, while the other blade assembly swings freely. This achieves the analysis of individual user behavior and objective environment to determine the user's intentions and adaptively adjusts the indoor unit's swing mode, improving swing control accuracy and optimizing the user experience while considering individual user differences and group needs.

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more.

[0048] It should be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. As used herein, unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the” are intended to include the plural forms.

[0049] The terms “comprising” and “including” indicate the presence of the described feature, whole, step, operation, element and / or component, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components and / or collections thereof.

[0050] Figure 1 This is one of the flowcharts illustrating the radar-based air conditioning swing control method provided by the present invention. For example... Figure 1 As shown, the radar-based air conditioning swing control method provided in this embodiment of the invention includes: step 101, obtaining the behavioral state information of each user based on the contour information of each user monitored by the radar module.

[0051] It should be noted that the execution subject of the radar-based air conditioning swing control method provided in this embodiment of the invention is a radar-based air conditioning swing control device.

[0052] The application scenario of the radar-based air conditioning swing control method provided in this embodiment of the invention is that when a user activates the air conditioner, the user's individual behavior state is determined by the contour information fed back in real time by the radar module, and the air supply mode is adjusted in combination with the indoor light level.

[0053] The radar module periodically monitors all individual users in the room at specified time intervals and sends the contour information of each user to the radar-based air conditioning swing control device. This embodiment of the invention does not specifically limit the working cycle of the radar module.

[0054] Optionally, the radar module can perform data acquisition operations at the default duty cycle.

[0055] Optionally, the user can issue a cycle change command, causing the radar module to receive and respond to the command, changing the working cycle to the cycle indicated by the command for data acquisition.

[0056] It should be noted that before step 101, the user needs to send an activation command through the transmission medium to activate the air conditioner's operating mode, so that the indoor unit of the air conditioner operates at the default fan speed of the mode, while the outdoor unit operates at the default frequency of the mode.

[0057] Optionally, the user can transmit activation commands through the control device and the air conditioning system via wireless communication, so that the air conditioning system initializes its working mode and starts the radar module.

[0058] Optionally, the user can issue an activation command via voice interaction. The air conditioning system receives the activation command, performs voice recognition, initializes the working mode, and starts the radar module.

[0059] Specifically, in step 101, after the air conditioner starts its working mode, the radar-based air conditioner swing control device controls the receiving radar module to collect the contour information of each user in the space where the air conditioner is located in real time, and analyzes the behavior action model of each user under the current contour to obtain the current behavior status information of each user.

[0060] The embodiments of the present invention do not specifically limit the type and number of radar sensing devices in the radar module.

[0061] For example, a radar module may include a lidar, an infrared sensor, etc.

[0062] Optionally, millimeter-wave radar has a horizontal detection range of ±75°, a vertical detection range of ±40°, a detection range of up to 8 meters, a distance output accuracy of 0.1 meters, an angle output accuracy of 1°, and does not involve privacy issues, is not affected by light, and has a fast response speed.

[0063] Therefore, the radar-based air conditioning swing control device can analyze the user's individual behavioral state based on the user's individual profile information collected in real time by the millimeter-wave radar.

[0064] For example, the radar module may include multiple sensing elements such as millimeter-wave radar, lidar, and infrared sensors. The radar-based air conditioning swing control device integrates the contour information collected by each sensing element to comprehensively depict the real-time behavior of the individual user.

[0065] For example, millimeter-wave radar can be used to collect the contour information of individual users. Based on the mapping relationship between contour information and behavior based on a large amount of prior data, the behavior corresponding to the current contour shape of the individual user can be directly obtained.

[0066] Step 102: If the target user's behavior status is determined to be lying down, obtain the indoor light intensity collected by the light sensing module in the space where the air conditioner is located.

[0067] The target user individual is any one of the user individuals currently present in the room.

[0068] Specifically, in step 102, the radar-based air conditioning swing control device analyzes the behavioral status information of all individual users. If it is determined that the behavioral status information of at least one individual user points to a lying position, it means that at least one individual user in the current indoor space has a tendency to sleep. After identifying this individual user as the target individual user, the device receives the indoor light intensity sensed by the light sensing module deployed on the indoor unit of the air conditioner, and uses this as a criterion for adaptively adjusting the air supply mode for the target individual user.

[0069] Step 103: When it is determined that the indoor light sensitivity is greater than the first preset threshold, control the first sway blade assembly to point to the lying position of the target user individual for fixed air supply, and control the second sway blade assembly to swing freely for sweeping air.

[0070] The first oscillating vane assembly is one in which the vane arrangement direction is perpendicular to the lying direction of the target user. The second oscillating vane assembly is any other oscillating vane assembly besides the first one. The oscillating vane assembly includes a horizontal oscillating vane assembly and a vertical oscillating vane assembly.

[0071] It should be noted that the indoor unit of the air conditioner has a sway blade assembly inside the air outlet cavity for air guidance. Based on the arrangement of the blades, it can be divided into vertically arranged horizontal sway blade assemblies, which oscillate vertically during operation, and horizontally arranged vertical sway blade assemblies, which oscillate horizontally during operation.

[0072] It should be noted that the first preset threshold refers to the threshold for setting the indoor light sensitivity.

[0073] The first preset threshold is used to measure the indoor light sensitivity. When the indoor light sensitivity is greater than the threshold, it indicates that the current objective environment is daytime. Conversely, it indicates that it is nighttime, or that the indoor space blocks most of the outdoor light during the day. The embodiment of the present invention does not specifically limit the value of the first preset threshold.

[0074] For example, the first preset threshold can be a numerical value, such as 50 lumens (lm).

[0075] Specifically, in step 103, the radar-based air conditioning swing control device compares the current indoor light intensity with a first preset threshold:

[0076] If the current indoor light intensity is greater than the first preset threshold, it indicates that the target user tends to have short-term or light sleep during the day. In this case, under the current working mode (cooling or heating), the first oscillating blade assembly perpendicular to the target user's lying position should be fixed to deliver airflow towards the target user's lying position, while the remaining second oscillating blade assembly should continue to deliver airflow freely. This approach fails to consider both directional airflow to allow the user to quickly feel the optimal body temperature and avoiding the harm to the human body caused by continuous directional airflow through partial spatial airflow disturbance when the user is in a light sleep state.

[0077] In this embodiment of the invention, when the radar module detects that at least one user is lying down, and the light sensor module collects the current indoor light intensity, and the objective environment is determined to be daytime through threshold comparison using the indoor light intensity, the system decides to adjust the indoor unit's swing mode. This involves arranging the arbiter blades perpendicular to the user's lying position to direct airflow towards that user, while allowing the other arbiter blades to swing freely. This achieves the analysis of individual user behavior and the objective environment to determine the user's intentions and adaptively adjusts the indoor unit's swing mode. It improves the control accuracy of the swing mode while considering individual user differences and group needs, thus optimizing the user experience.

[0078] Based on any of the above embodiments, when it is determined that the indoor light sensitivity is greater than a first preset threshold, the first sway blade assembly is controlled to point to the lying position of the target user individual for fixed air supply, and the second sway blade assembly is controlled to swing freely for sweeping air, including: when it is determined that the difference between the first endpoint position and the second endpoint position of the target user individual in the air conditioning coordinate system in the Y-axis direction is less than or equal to a second preset threshold, the first sway blade assembly is set as a horizontal sway blade assembly, and the second sway blade assembly is set as a vertical sway blade assembly.

[0079] The air conditioning coordinate system is established with the horizontal line where the indoor unit of the air conditioner is located in the horizontal plane as the X-axis and the horizontal line perpendicular to the indoor unit of the air conditioner as the Y-axis; the first endpoint position and the second endpoint position are the position coordinates of the outline of the target user individual at the left and right boundaries in the horizontal direction, respectively.

[0080] It should be noted that the air conditioning coordinate system takes the position of the center of mass of the indoor unit of the air conditioner in the indoor space as the origin, and the horizontal line where the indoor unit is located as the X-axis. The direction to the left of the origin is defined as the positive direction of the X-axis, and the direction to the right of the origin is defined as the negative direction of the X-axis. The vertical blade assembly of the air conditioner swings left and right between the positive and negative directions of the X-axis.

[0081] The Y-axis is defined as the straight line passing through the origin and perpendicular to the X-axis in the horizontal plane where the X-axis is located, and the Z-axis is defined as the vertical line passing through the origin and perpendicular to the XY plane. The direction vertically upward from the origin is defined as the positive direction of the Z-axis, and the direction vertically downward is defined as the negative direction of the Z-axis. The air conditioner's oscillating blade assembly oscillates up and down between the positive and negative directions of the Z-axis.

[0082] It should be noted that the second preset threshold refers to the threshold set for the difference in coordinate values ​​of the boundary endpoints on the Y-axis.

[0083] The second preset threshold is used to compare the difference between the first endpoint position and the second endpoint position in the Y-axis direction. The closer the difference is to the threshold, the closer the lying direction of the target user is to the horizontal direction corresponding to the X-axis. The embodiment of the present invention does not specifically limit the value of the second preset threshold.

[0084] For example, the second preset threshold can be a numerical value, such as 0.

[0085] For example, the second preset threshold can also be an interval, set with reference to the acceptable deviation range of the X-axis.

[0086] Specifically, in step 103, the radar-based air conditioning swing control device extracts the position coordinates of the left and right boundaries in the horizontal direction from the contour information corresponding to the target user individual in a lying position, and uses them as the first endpoint position and the second endpoint position respectively, and calculates the difference between the Y-axis coordinate values ​​of the first endpoint position and the second endpoint position.

[0087] If the difference between the two is less than or equal to the second preset threshold, it means that the target user's lying direction is horizontal or close to horizontal. In this case, the first swing blade component is set as a vertically arranged horizontal swing blade component, and the second swing blade component is set as a vertical swing blade component accordingly.

[0088] Conversely, if the target user's lying direction is vertical, then the first swing blade component is set as a horizontally arranged vertical swing blade component, and the second swing blade component is set as a horizontal swing blade component accordingly.

[0089] Based on the first endpoint position and the second endpoint position, a first execution angle is determined for pointing to the supine position of the target user individual.

[0090] Specifically, the radar-based air conditioning swing control device uses the difference in coordinate values ​​of the first and second endpoint positions of the target user individual on the X and Z axes to locate the target user individual, and calculates the angle value of the sway blade assembly relative to the XY plane based on the position of the target user individual as the first execution angle for aligning with the target user individual.

[0091] During the process of controlling the vertical sway blade assembly to swing left and right, the horizontal sway blade assembly stops swinging up and down when it is determined that the horizontal sway blade assembly has moved to the first execution angle.

[0092] Specifically, after the radar-based air conditioning swing control device sets the first and second swing blade components, it drives the vertical swing blade component to swing left and right, and at the same time drives the horizontal swing blade component to swing up and down, until the horizontal swing blade component moves to the calculated first execution angle, then stops swinging in the up and down direction and performs fixed air supply.

[0093] In this embodiment of the invention, based on the first and second endpoint positions of the user's individual silhouette on the left and right boundaries, when the target user is lying horizontally parallel to the air conditioner, the first swing blade assembly is set as a horizontal swing blade assembly, and the second swing blade assembly is set as a vertical swing blade assembly. The calculated first execution angle controls the horizontal swing blade assembly to provide directional airflow, while the vertical swing blade assembly swings freely. This achieves the goal of prioritizing the needs of users who can comfortably rest in a horizontal lying position during the daytime in a group environment, while adapting the indoor unit's swing mode accordingly. It improves the swing control accuracy and optimizes the user experience while considering both individual user differences and group needs.

[0094] Based on any of the above embodiments, when it is determined that the indoor light sensitivity is greater than a first preset threshold, the first sway blade assembly is controlled to point to the lying position of the target user individual for fixed air supply, and the second sway blade assembly is controlled to swing freely for sweeping air, including: when it is determined that the difference between the third endpoint position and the fourth endpoint position of the target user individual in the air conditioning coordinate system in the X-axis direction is less than or equal to a third preset threshold, the first sway blade assembly is set as a vertical sway blade assembly, and the second sway blade assembly is set as a horizontal sway blade assembly.

[0095] The air conditioning coordinate system is established with the horizontal line where the indoor unit of the air conditioner is located in the horizontal plane as the X-axis and the horizontal line perpendicular to the indoor unit of the air conditioner as the Y-axis; the third endpoint position and the fourth endpoint position are the position coordinates of the outline of the target user individual at the upper and lower boundaries in the vertical direction, respectively.

[0096] It should be noted that the third preset threshold refers to the threshold set for the difference in coordinate values ​​of the boundary endpoints on the X-axis.

[0097] The third preset threshold is used to compare the difference between the third endpoint position and the fourth endpoint position in the X-axis direction. The closer the difference is to the threshold, the closer the lying direction of the target user is to the vertical direction corresponding to the Y-axis. The embodiment of the present invention does not specifically limit the value of the third preset threshold.

[0098] For example, the third preset threshold can be set in the same way as the second preset threshold.

[0099] Specifically, in step 103, the radar-based air conditioning swing control device extracts the position coordinates of the upper and lower boundaries in the vertical direction from the contour information corresponding to the target user individual in a lying position, and uses them as the third endpoint position and the fourth endpoint position respectively, and calculates the difference between the X-axis coordinate values ​​of the third endpoint position and the fourth endpoint position.

[0100] If the difference between the two is less than or equal to the third preset threshold, it means that the target user's lying direction is vertical or close to vertical. In this case, the first swing blade component is set as a horizontally arranged vertical swing blade component, and the second swing blade component is set as a horizontal swing blade component accordingly.

[0101] Conversely, if the target user is lying horizontally, the first swing blade component is set as a vertically arranged horizontal swing blade component, and the second swing blade component is set as a vertical swing blade component accordingly.

[0102] Based on the third endpoint position and the fourth endpoint position, a second execution angle is determined for pointing to the supine position of the target user individual.

[0103] Specifically, the radar-based air conditioning swing control device uses the difference in coordinate values ​​of the third and fourth endpoint positions of the target user individual on the Y and Z axes to locate the target user individual, and calculates the angle value of the sway blade assembly relative to the YZ plane based on the position of the target user individual as the second execution angle for aligning with the target user individual.

[0104] During the process of controlling the horizontal sway blade assembly to swing up and down, the horizontal sway blade assembly stops swinging left and right when it is determined that the vertical sway blade assembly has moved to the second execution angle.

[0105] Specifically, after the radar-based air conditioning swing control device sets the first and second swing blade components, it drives the horizontal swing blade component to swing up and down while also driving the vertical swing blade component to swing left and right until the vertical swing blade component moves to the calculated second execution angle, at which point the swinging in the left and right directions stops and fixed air supply is performed.

[0106] In this embodiment of the invention, based on the third and fourth endpoint positions of the user's individual profile at the upper and lower boundaries, when the target user is lying vertically perpendicular to the air conditioner, the first swing blade assembly is set as a vertical swing blade assembly, and the second swing blade assembly is set as a horizontal swing blade assembly. The calculated second execution angle controls the vertical swing blade assembly to provide directional airflow, while the horizontal swing blade assembly swings freely. This achieves the goal of prioritizing the needs of users who can comfortably rest in a vertically lying posture during the daytime in a group environment, while adapting the indoor unit's swing mode accordingly. It improves the swing control accuracy and optimizes the user experience while considering both individual user differences and group needs.

[0107] Based on any of the above embodiments, the step of obtaining behavioral state information of each user individual based on the contour information of each user individual monitored by the radar module includes: when it is determined from the radar module that at least one user individual exists indoors, determining a first contour length and a second contour length based on the contour information of each user individual.

[0108] Wherein, the first contour length is the length information of the user's individual contour in the Z-axis direction of the air conditioning coordinate system. The second contour length is the length information of the user's individual contour in the X-axis direction of the air conditioning coordinate system.

[0109] Specifically, in step 101, the radar-based air conditioning swing control device drives the radar module to perform human body perception. When it is determined that there is at least one user in the current room, the contour length information extracted from the contour information of each user in the Z-axis direction is used as the first contour length, and the contour width information extracted in the X-axis direction is used as the second contour length, so as to characterize the body volume of the human torso in the longitudinal and transverse dimensions.

[0110] If the length of the first contour is greater than the length of the second contour, then the behavior state information is set to the vertical state.

[0111] Specifically, the radar-based air conditioning swing control device compares the length of the first contour and the length of the second contour. If the length of the first contour is greater than the length of the second contour, it means that the body length in the longitudinal direction is longer than the body length in the lateral direction. In this case, the user's current behavioral state information is regarded as the vertical state, which includes standing and sitting states.

[0112] If the length of the first contour is less than or equal to the length of the second contour, the behavior state information is set to the lying-flat state.

[0113] Specifically, if the radar-based air conditioning swing control device determines that the length of the first contour is not greater than the length of the second contour, that is, the body length of the torso is longer in the horizontal direction than in the vertical direction, then the user's current behavioral state information will be regarded as a lying state.

[0114] In this embodiment of the invention, when at least one user is detected indoors by a radar module, the behavioral state information of the user is determined by utilizing the relationship between the lengths of the first and second contours extracted in the horizontal and vertical directions from the contour information of each user. This enables comprehensive posture analysis based on the lengths of the user's contour in both the horizontal and vertical dimensions, improving the accuracy of behavior analysis.

[0115] Based on any of the above embodiments, before obtaining the behavioral status information of each user individual based on the contour information of each user individual monitored by the radar module, the method further includes: when it is determined by the radar module that there are no user individuals in the room, calculating the duration of the unmanned state in the room.

[0116] Specifically, the radar-based air conditioning swing control device drives the radar module to detect human presence. When it is determined that there are no individual users in the room, the system calculates the duration of the room being unoccupied up to the current moment.

[0117] When the duration of the indoor unoccupied state reaches the target level, the indoor unit of the air conditioner is controlled to operate in the energy-saving mode corresponding to the target level until the maximum level is reached and the indoor unit of the air conditioner is shut down.

[0118] The target levels include multiple levels with increasing durations for unoccupied indoor environments. The operating power of each progressively increasing level in its corresponding energy-saving mode decreases.

[0119] It should be noted that before step 101, at least two consecutive duration intervals need to be defined between the upper and lower limits of the duration of the indoor unoccupied state in order to quantify different duration levels.

[0120] Accordingly, based on the set N duration levels, the operating power of the indoor unit also needs to be divided into N target levels.

[0121] Wherein, N is an integer greater than or equal to 1, and the present invention does not specifically limit the division of the target gear.

[0122] For example, a radar-based air conditioning swing control device can divide the indoor unoccupied state into multiple time intervals between the upper and lower limits. The target power level corresponding to each interval also decreases sequentially with the same operating power interval value, corresponding to different energy-saving modes.

[0123] For example, a radar-based air conditioning swing control device can customize multiple duration intervals between the upper and lower limits of the duration of indoor unoccupied conditions. Correspondingly, the proportion of the operating power corresponding to the target setting in the rated power range is the same as the proportion of the sub-interval corresponding to the target setting in the total range formed by the upper and lower duration limits.

[0124] Specifically, the radar-based air conditioning swing control device uses the time interval corresponding to the duration of the indoor unoccupied state as the target level and controls the indoor air conditioning unit to operate in the energy-saving mode corresponding to the target level.

[0125] If the duration of the indoor unit being unoccupied continues to increase to the maximum setting corresponding to the last duration interval, the indoor unit of the air conditioner will be turned off.

[0126] In this embodiment of the invention, the method of classifying the energy-saving modes corresponding to different levels is not specifically limited.

[0127] For example, when the indoor environment is unoccupied for 10 minutes, the system enters the default energy-saving mode. For every additional 2 minutes thereafter, the fan motor reduces its power by 20% from its original level, until the air conditioner stops operating after 20 minutes.

[0128] In this embodiment of the invention, when the radar module detects that no individual user is present indoors, the indoor unit of the air conditioner is controlled to operate in the energy-saving mode corresponding to the target setting based on the duration of the unoccupied state. This achieves energy savings by gradually reducing the operating frequency of the air conditioner as the duration of unoccupied indoor time increases.

[0129] Based on any of the above embodiments, after obtaining the indoor light intensity collected by the light sensing module in the space where the air conditioner is located, the method further includes: when it is determined that the indoor light intensity is less than or equal to a first preset threshold, starting the sleep mode, and controlling the horizontal sway blade assembly to swing up and down while also controlling the vertical sway blade assembly to swing left and right.

[0130] Specifically, after step 102, if the radar-based air conditioning swing control device determines that the current indoor light intensity is less than or equal to the first preset threshold, it indicates that the target user's sleep tends to be long-term sleep or deep sleep in the objective environment. Therefore, it is necessary to maintain the cooling or heating operation while still in sleep mode, so that the horizontal swing blade assembly and the vertical swing blade assembly swing back and forth within their respective swing ranges.

[0131] For example, Figure 2 This is the second flowchart illustrating the radar-based air conditioning swing control method provided by this invention. Figure 2As shown in the figure, this invention provides a specific implementation method for an air conditioning swing control method based on radar:

[0132] (1) After the air conditioner is turned on, the signal of people in the room is collected by millimeter-wave radar. If no one is present, proceed to step (2). If no one is present, proceed to step (3).

[0133] (2) If no one is in the room for 10 minutes, the default energy-saving mode will be entered. If the fan motor runs at 80% power for 12 minutes, at 60% power for 14 minutes, and so on until the air conditioner stops running when the time is increased to 20 minutes.

[0134] (3) Compare the vertical length (first contour length) of the human body with the horizontal length (greater than the second contour length). If the vertical length is greater than the horizontal length, then the person is standing and proceed to step (4). Conversely, if the vertical length is less than the horizontal length, then the person is lying down and proceed to step (5).

[0135] (4) If all users are standing, the original working mode will be used.

[0136] (5) Detect the light sensitivity in the room. If the light sensitivity is less than 50lm, proceed to step (6); otherwise, proceed to step (7).

[0137] (6) If the light sensitivity is less than 50lm, it is determined that the objective environment is not daytime. Based on the sleep mode, both the horizontal guide plate and the vertical swing blade are allowed to swing freely.

[0138] (7) If the light sensitivity is not less than 50lm, the objective environment is determined to be daytime, and the lying direction is determined by the individual outline information of the user in a lying position.

[0139] (8) If the lying position is parallel to the horizontal line of the air conditioner, the horizontal guide plate will lock the person's position, and the vertical blades will swing freely. Conversely, if the lying position is perpendicular to the horizontal line of the air conditioner, the vertical blades will lock the person's position, and the horizontal guide plate will swing freely.

[0140] In this embodiment of the invention, when the radar module detects that at least one user is lying down, and the light sensor module collects the current indoor light level, and the objective environment is determined to be outside of daytime by threshold comparison using the indoor light level, a decision is made to activate sleep mode and implement free airflow. This achieves the goal of increasing airflow disturbance in the space through free airflow in both vertical and horizontal dimensions when the group's need is to rest deeply in a lying position outside of daytime. This avoids the health hazards caused by direct airflow while the user is sleeping, thus optimizing the user experience.

[0141] Figure 3This is a schematic diagram of the radar-based air conditioning swing control device provided by the present invention. Based on any of the above embodiments, such as... Figure 3 As shown, the device includes a behavior analysis module 310, a light intensity monitoring module 320, and a control module 330, wherein:

[0142] The behavior analysis module 310 is used to obtain the behavior status information of each user based on the contour information of each user monitored by the radar module.

[0143] The light monitoring module 320 is used to obtain the indoor light intensity collected by the light sensing module in the space where the air conditioner is located when the behavior status information of the target user is determined to be lying down.

[0144] The control module 330 is used to control the first swaying blade assembly to point to the lying position of the target user individual for fixed air supply when it is determined that the indoor light sensitivity is greater than the first preset threshold, and to control the second swaying blade assembly to swing freely for sweeping air.

[0145] The first sway vane assembly is a sway vane assembly whose sway vane arrangement direction is perpendicular to the lying direction of the target user individual. The second sway vane assembly is a sway vane assembly other than the first sway vane assembly. The sway vane assembly includes horizontal sway vane assemblies and vertical sway vane assemblies. The target user individual is any one of the users currently present in the room.

[0146] Specifically, the behavior analysis module 310, the light intensity monitoring module 320, and the control module 330 are electrically connected in sequence.

[0147] The behavior analysis module 310 receives the contour information of each user in the space where the air conditioner is located in real time from the radar module, and analyzes the behavior action model of each user under the current contour to obtain the current behavior status information of each user.

[0148] The light monitoring module 320 analyzes the behavioral status information of all individual users. If it is determined that the behavioral status information of at least one individual user points to a lying position, it means that at least one individual user in the current indoor space has a tendency to sleep. After identifying this individual user as the target individual user, the module receives the indoor light intensity sensed by the light sensing module deployed on the indoor unit of the air conditioner. This information is used as a criterion for adaptively adjusting the air supply mode for the target individual user.

[0149] The control module 330 compares the current indoor light level with a first preset threshold:

[0150] If the current indoor light intensity is greater than the first preset threshold, it indicates that the target user tends to have short-term or light sleep during the day. In this case, under the current working mode (cooling or heating), the first oscillating blade assembly perpendicular to the target user's lying position should be fixed to deliver airflow towards the target user's lying position, while the remaining second oscillating blade assembly should continue to deliver airflow freely. This approach fails to consider both directional airflow to allow the user to quickly feel the optimal body temperature and avoiding the harm to the human body caused by continuous directional airflow through partial spatial airflow disturbance when the user is in a light sleep state.

[0151] Optionally, the control module 330 includes a first component partitioning unit, a first execution angle determination unit, and a first control unit, wherein:

[0152] The first component division unit is used to set the first swing blade component as a horizontal swing blade component and the second swing blade component as a vertical swing blade component when the difference between the first endpoint position and the second endpoint position of the target user individual in the air conditioning coordinate system in the Y-axis direction is less than or equal to a second preset threshold.

[0153] The first execution angle determination unit is used to determine a first execution angle for pointing to the lying position of the target user individual based on the first endpoint position and the second endpoint position.

[0154] The first control unit is used to stop the vertical swinging of the horizontal swinging blade assembly when it is determined that the horizontal swinging blade assembly has moved to the first execution angle during the process of controlling the vertical swinging blade assembly to swing left and right.

[0155] The air conditioning coordinate system is established with the horizontal line where the indoor unit of the air conditioner is located in the horizontal plane as the X-axis and the horizontal line perpendicular to the indoor unit as the Y-axis. The first endpoint position and the second endpoint position are the position coordinates of the left and right boundaries of the outline of the target user individual in the horizontal direction, respectively.

[0156] Optionally, the control module 330 includes a second component partitioning unit, a second execution angle determination unit, and a second control unit, wherein:

[0157] The second component division unit is used to set the first swing blade component as a vertical swing blade component and the second swing blade component as a horizontal swing blade component when the difference between the third endpoint position and the fourth endpoint position of the target user individual in the air conditioning coordinate system in the X-axis direction is less than or equal to a third preset threshold.

[0158] The second execution angle determination unit is used to determine a second execution angle for pointing to the lying position of the target user individual based on the third endpoint position and the fourth endpoint position.

[0159] The second control unit is used to stop the left-right swinging of the vertical sway blade assembly when it is determined that the vertical sway blade assembly has moved to the second execution angle during the process of controlling the horizontal sway blade assembly to swing up and down.

[0160] The air conditioning coordinate system is established with the horizontal line where the indoor unit of the air conditioner is located in the horizontal plane as the X-axis and the line perpendicular to the horizontal line where the indoor unit is located as the Y-axis. The third endpoint position and the fourth endpoint position are the position coordinates of the upper and lower boundaries of the outline of the target user individual in the vertical direction, respectively.

[0161] Optionally, the behavior analysis module 310 includes a contour extraction unit and a behavior analysis unit, wherein:

[0162] The contour extraction unit is used to determine a first contour length and a second contour length based on the contour information of each user individual when the radar module determines that at least one user individual exists indoors.

[0163] The behavior analysis unit is used to set the behavior state information to vertical if the length of the first contour is greater than the length of the second contour.

[0164] If the length of the first contour is less than or equal to the length of the second contour, the behavior state information is set to the lying-flat state.

[0165] Wherein, the first contour length is the length information of the user's individual contour in the Z-axis direction of the air conditioning coordinate system. The second contour length is the length information of the user's individual contour in the X-axis direction of the air conditioning coordinate system.

[0166] Optionally, the behavior analysis module 310 also includes an unmanned status monitoring unit and an energy-saving control unit, wherein:

[0167] The unmanned status monitoring unit is used to calculate the duration of the unmanned status indoors when the radar module determines that there are no individual users indoors.

[0168] The energy-saving control unit is used to control the indoor air conditioner to operate in an energy-saving mode corresponding to the target level when the duration of the indoor unoccupied state reaches the target level, until the maximum level is reached and the indoor air conditioner is shut down.

[0169] The target levels include multiple levels with increasing durations for unoccupied indoor environments. The operating power of each progressively increasing level in its corresponding energy-saving mode decreases.

[0170] Optionally, the control module 330 is also used to activate the sleep mode when it is determined that the indoor light intensity is less than or equal to a first preset threshold, and to control the horizontal sway blade assembly to swing up and down while also controlling the vertical sway blade assembly to swing left and right.

[0171] The radar-based air conditioning swing control device provided in this embodiment of the invention is used to execute the radar-based air conditioning swing control method of the present invention. Its implementation method is the same as that of the radar-based air conditioning swing control method provided in this invention, and it can achieve the same beneficial effects, so it will not be described again here.

[0172] In this embodiment of the invention, when the radar module detects that at least one user is lying down, and the light sensor module collects the current indoor light intensity, and the objective environment is determined to be daytime through threshold comparison using the indoor light intensity, the system decides to adjust the indoor unit's swing mode. This involves arranging the arbiter blades perpendicular to the user's lying position to direct airflow towards that user, while allowing the other arbiter blades to swing freely. This achieves the analysis of individual user behavior and the objective environment to determine the user's intentions and adaptively adjusts the indoor unit's swing mode. It improves the control accuracy of the swing mode while considering individual user differences and group needs, thus optimizing the user experience.

[0173] Figure 4 This is a structural schematic diagram of the air conditioner provided by the present invention. Based on any of the above embodiments, such as... Figure 4 As shown, the air conditioner includes an indoor unit 410 and an outdoor unit 420. The indoor unit 410 houses a control processor 411, a light sensor module 412, and a radar module 413. The light sensor module 412 is integrated into the display panel of the indoor unit 410. The radar module 413 is disposed on the surface of the housing of the indoor unit 410. The air conditioner also includes a memory and programs or instructions stored in the memory that can run on the control processor 411. When executed by the control processor 411, the program or instructions perform the radar-based air conditioning swing control method described above.

[0174] The radar module 413 includes a millimeter-wave radar.

[0175] Specifically, the air conditioner includes an indoor unit 410 and an outdoor unit 420. A light-sensing module 412 is integrated on the display panel of the indoor unit 410, and a radar module 413 is embedded on the surface of the indoor unit 410's casing. When the control processor 411 detects the behavioral state information corresponding to each user's current profile based on the radar module 413 and confirms that the user is lying down, it collects the indoor light intensity of the space where the air conditioner is located through the light-sensing module. If the current indoor light intensity is greater than a first preset threshold, it indicates that the target user tends to have short-term or light sleep during the day. In this case, under the current operating mode (cooling or heating), the first louver assembly perpendicular to the target user's lying direction is controlled to deliver airflow towards the target user's lying position, while the remaining second louver assembly continues to deliver airflow freely. This approach fails to consider both directional airflow to allow the user to quickly feel the optimal body temperature and avoiding the harm caused by continuous directional airflow through partial spatial airflow disturbance, even in a user's light sleep state.

[0176] If the current indoor light intensity is less than or equal to the first preset threshold, it indicates that the target user's sleep pattern in the objective environment tends to be long-term sleep or deep sleep. Therefore, cooling or heating operations are required while still maintaining sleep mode, so that the horizontal and vertical oscillating blade components can swing back and forth within their respective swing ranges.

[0177] In this embodiment of the invention, when the radar module detects that at least one user is lying down, and the light sensor module collects the current indoor light intensity, and the objective environment is determined to be daytime through threshold comparison using the indoor light intensity, the system decides to adjust the indoor unit's swing mode. This involves arranging the arbiter blades perpendicular to the user's lying position to direct airflow towards that user, while allowing the other arbiter blades to swing freely. This achieves the analysis of individual user behavior and the objective environment to determine the user's intentions and adaptively adjusts the indoor unit's swing mode. It improves the control accuracy of the swing mode while considering individual user differences and group needs, thus optimizing the user experience.
