Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to an air conditioning fan speed control method, device and air conditioner. Background Technology

[0002] Air conditioners are essential equipment in indoor spaces. They can control the indoor temperature to provide users with a comfortable living or working environment.

[0003] In existing technologies, air conditioners typically rely on built-in centrifugal or cross-flow fans for airflow. Centrifugal fans have higher air pressure, allowing for a relatively long airflow distance when used in air conditioners, but resulting in a stronger draft and poor user comfort. Therefore, cross-flow fans with lower air pressure are usually chosen, as their airflow distance is shorter, reducing the draft to some extent. Furthermore, traditional air conditioners typically deliver air at a fixed speed. In real-world scenarios, a fixed airflow speed often doesn't match the activities of individuals indoors, making it difficult to achieve optimal temperature control and resulting in low efficiency in regulating indoor temperature. Summary of the Invention

[0004] This invention provides an air conditioning fan speed control method, device, and air conditioner to solve the problem of low temperature control efficiency caused by the mismatch between fixed fan speed and the behavior of individuals indoors in the prior art.

[0005] This invention provides an air conditioning fan speed control method, applied to an indoor air conditioning unit having an air supply device and multiple air outlets; the air supply device includes multiple cross-flow fans, each cross-flow fan corresponding to one air outlet, and the control method includes:

[0006] When the radar module determines that there is at least one human being in motion in the indoor space, the radar module is used to capture the moving speed of the target human being relative to the indoor air conditioning unit and the distance between the human and the unit.

[0007] Based on the moving speed and / or distance between the target human individual and the indoor unit of the air conditioner, determine the target fan speed that matches the target human individual in the speed dimension and / or distance dimension, so as to at least control the target cross-flow fan to operate at the target fan speed;

[0008] The radar module is installed in the indoor unit of the air conditioner; the target human individual is a human individual in motion in the indoor space; the target cross-flow fan is a cross-flow fan matched with the position of the target human individual in the indoor space.

[0010] If the moving speed of the target human individual relative to the indoor unit of the air conditioner is less than or equal to the first speed threshold, the target fan speed is determined based on the moving speed and the rated maximum speed of the cross-flow fan.

[0011] If the target human individual moves at a speed greater than a first speed threshold relative to the indoor unit of the air conditioner, then the target fan speed is set to the rated maximum speed of the cross-flow fan.

[0012] The first speed threshold is determined based on the speed at which a human individual moves within an indoor space.

[0015] If the distance between the target human individual and the air conditioner indoor unit is greater than a first distance threshold, then the target fan speed is set to the rated maximum speed of the cross-flow fan;

[0016] The first distance threshold is determined based on the head of the indoor unit of the air conditioner.

[0017] According to an air conditioning fan speed control method provided by the present invention, the step of determining a target fan speed that matches the target human individual in the speed and distance dimensions based on the moving speed of the target human individual relative to the indoor unit of the air conditioner and the distance between the human and the unit includes:

[0018] If the moving speed of the target human individual relative to the indoor unit of the air conditioner is less than or equal to the second speed threshold, then the first fan speed is determined based on the moving speed and the rated maximum speed of the cross-flow fan.

[0019] If the distance between the target human individual and the air conditioner indoor unit is determined to be less than or equal to the second distance threshold, then the second fan speed is determined based on the human-machine distance and the rated maximum speed of the cross-flow fan.

[0021] The second speed threshold is determined based on the speed at which a human being moves within an indoor space; the second distance threshold is determined based on the head of the indoor air conditioning unit.

[0022] According to an air conditioning fan speed control method provided by the present invention, the calculation formula for the target fan speed is as follows:

[0030] The yaw blade assembly is disposed within the cavity of the air outlet to change the output airflow direction of the cross-flow fan.

[0031] The present invention also provides an air conditioning fan speed control device, comprising:

[0032] The motion capture module is used to capture the moving speed and distance between the target human individual and the indoor air conditioning unit when the radar module determines that at least one human individual is in motion in the indoor space.

[0033] The fan control module is used to determine the target fan speed that matches the target human individual in the speed dimension and / or distance dimension based on the moving speed and / or distance of the target human individual relative to the indoor unit of the air conditioner, so as to control the target cross-flow fan to run at the target fan speed;

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.

[0047] 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.

[0048] 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.

[0049] Figure 1 This is one of the flowcharts illustrating the air conditioning fan speed control method provided by this invention. For example... Figure 1 As shown, the air conditioning fan speed control method provided in this embodiment of the invention is applied to an indoor air conditioning unit with an air supply device and multiple air outlets; the air supply device includes multiple cross-flow fans, each cross-flow fan corresponding to an air outlet, and the control method includes: step 101, when it is determined by the radar module that at least one human individual is in motion in the indoor space, the radar module is used to capture the movement speed of the target human individual and the distance between the human and the machine.

[0050] The radar module is installed in the indoor unit of an air conditioner. The target human individual is a human individual in motion within the indoor space.

[0051] It should be noted that the air conditioning fan speed control method provided in this embodiment of the invention is executed by an air conditioning fan speed control device.

[0052] The application scenario of the air conditioning fan speed control method provided in this embodiment of the invention is as follows: when a user activates the air conditioner, the motion state of an individual relative to the indoor unit of the air conditioner is determined by the real-time feedback of sensor data from the radar module. The speed of one or more fans in the air supply device is adjusted so that the air supply after the fan speed is adjusted matches the motion state of the individual in the room.

[0053] The radar module periodically collects displacement information of all individuals in the room at specified time intervals, and sends this displacement information to the air conditioning fan speed 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 working mode, so that the indoor unit of the air conditioner runs each cross-flow fan at the default fan speed of the mode, while the outdoor unit runs 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 air conditioner fan speed control device receives real-time sensing location information collected by the radar module for each individual in the space where the air conditioner is located, in order to monitor the behavior and activities of individuals in the indoor space:

[0060] If at least one individual's perceived position information changes over time during the observation period, indicating that the individual is in motion, then it is necessary to calculate the individual's instantaneous moving speed relative to the indoor air conditioner unit, as well as the straight-line human-machine distance between the individual and the indoor air conditioner unit, based on multiple sets of perceived position information of the individual during the observation period.

[0061] If the perceived position information of each individual does not change over time during the observation period, it means that all individuals are in a stationary state. In this case, it is necessary to continue to capture the movement of the individuals through the radar module until an individual is detected to have moved. Then, the individual is tracked and monitored. Based on the multiple sets of perceived position information of the individual during the observation period, the instantaneous moving speed of the individual relative to the indoor air conditioner unit and the straight-line human-machine distance between the individual and the indoor air conditioner unit are calculated.

[0062] In this embodiment of the invention, the type and number of radar sensing devices in the radar module are not specifically limited.

[0063] For example, a radar module may include a lidar, an infrared sensor, etc.

[0064] 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.

[0065] Therefore, the air conditioning fan speed control device uses the individual location information collected in real time by the millimeter-wave radar as the perceived location of the individual user.

[0066] For example, the radar module may include multiple sensing elements such as millimeter-wave radar, lidar, and infrared sensors. The air conditioning fan speed control device integrates the behavioral information collected by each sensing element to comprehensively depict the individual's real-time perceived location.

[0067] Step 102: Based on the moving speed and / or distance between the target human individual and the indoor unit of the air conditioner, determine the target fan speed that matches the target human individual in the speed dimension and / or distance dimension, so as to control the target cross-flow fan to run at the target fan speed.

[0068] The target cross-flow fan is a cross-flow fan that matches the position of the target human individual in the indoor space.

[0069] It should be noted that the k cross-flow fans in the air supply device can blow out cold air, hot air or natural air through their corresponding air outlets. According to the arrangement of the k air outlets, the air supply area of ​​the indoor unit of the air conditioner can be divided into multiple zones.

[0070] For example, in a wall-mounted air conditioner where the indoor unit is fixed to the wall, the number of horizontally distributed air outlets is much greater than the number of vertically distributed air outlets. Therefore, multiple zones can be vertically divided in the horizontal distribution of air outlets. When a target human individual walks to a certain zone, the cross-flow fan behind the air outlet corresponding to that zone can be used as the target cross-flow fan.

[0071] For example, in a floor-standing air conditioner where the indoor unit is placed on the ground, the number of air outlets distributed vertically is much greater than the number distributed horizontally. Therefore, the number of zones that can be divided by the horizontal distribution of air outlets is limited. When the target human individual moves horizontally relative to the indoor unit of the air conditioner, all cross-flow fans can be used as the target cross-flow fans.

[0072] Specifically, in step 102, the air conditioning fan speed control device can use the mapping relationship between the moving speed of the target human individual relative to the indoor unit of the air conditioner and the fan speed, as well as the mapping relationship between the human-machine distance of the target human individual relative to the indoor unit of the air conditioner and the fan speed, to calculate the target fan speed matched in a single dimension or multiple dimensions, and control the target cross-flow fan matched with the position of the target human individual in the indoor space to deliver air to the zone where the individual is currently located at the target fan speed. The speeds of other fans besides the target fan speed can be maintained at the default speed value of the activated working mode.

[0073] Understandably, after calculating the target fan speed, all cross-flow fans can be run at the target fan speed to accelerate temperature regulation efficiency.

[0074] This invention, based on radar modules capturing the movement speed and distance of a human in motion, calculates a target fan speed that matches the human's speed and / or distance in the speed and / or distance dimensions. This allows the indoor air conditioning unit to adjust the speed of some or all of its cross-flow fans. This enables adaptive adjustment of the air conditioning's airflow mode based on the behavior of individuals indoors, improving the efficiency of indoor temperature control and optimizing the user's airflow experience.

[0075] Based on any of the above embodiments, determining the target fan speed that matches the target human individual in the speed dimension based on the moving speed of the target human individual relative to the air conditioner indoor unit includes: if the moving speed of the target human individual relative to the air conditioner indoor unit is less than or equal to a first speed threshold, then determining the target fan speed based on the moving speed and the rated maximum speed of the cross-flow fan.

[0076] If the target human individual moves at a speed greater than a first speed threshold relative to the indoor unit of the air conditioner, then the target fan speed is set to the rated maximum speed of the cross-flow fan.

[0077] The first speed threshold is determined based on the speed at which a human individual moves within an indoor space.

[0078] It should be noted that the first velocity threshold is determined based on the velocity levels of various human individuals displaced within an indoor space. The first velocity threshold is used to benchmark the instantaneous movement velocity of human individuals within an indoor space, thus characterizing the degree of individual movement.

[0079] Specifically, in step 102, the air conditioning fan speed control device can use the mapping relationship between the moving speed of the target human individual relative to the indoor unit of the air conditioner and the fan speed to calculate the target fan speed that matches the speed dimension. When doing so, it is necessary to first perform a threshold judgment on the moving speed of the target human individual relative to the indoor unit of the air conditioner.

[0080] If the movement speed of the target human individual relative to the indoor unit of the air conditioner is less than or equal to the first speed threshold, it means that the individual's movement is not intense. Then, the conversion ratio from movement level to fan speed is calculated using the movement speed. Finally, the rated maximum speed of the cross-flow fan is multiplied by the conversion ratio from movement level to fan speed to obtain the target fan speed.

[0081] If the target human individual moves at a speed greater than the first speed threshold relative to the indoor unit of the air conditioner, indicating that the individual's movement is relatively intense, the speed of the cross-flow fan will be directly increased to the rated maximum speed.

[0082] In this embodiment of the invention, when adjusting the rotational speed of a cross-flow fan based on the movement speed captured by a human individual in motion using a radar module, the target fan speed is determined by comparing the movement speed with a first speed threshold. This enables adaptive adjustment of the air conditioning airflow mode based on the indoor individual's behavior in the speed dimension, improving the efficiency of indoor temperature control and optimizing the user's airflow experience.

[0083] Based on any of the above embodiments, determining the target fan speed that matches the target human individual in the speed dimension based on the human-machine distance between the target human individual and the air conditioner indoor unit includes: if the human-machine distance between the target human individual and the air conditioner indoor unit is less than or equal to a first distance threshold, then determining the target fan speed based on the human-machine distance and the rated maximum speed of the cross-flow fan.

[0084] If the distance between the target human individual and the air conditioner indoor unit is greater than a first distance threshold, then the target fan speed is set to the rated maximum speed of the cross-flow fan.

[0085] The first distance threshold is determined based on the head of the indoor unit of the air conditioner.

[0086] It should be noted that the first distance threshold is determined based on the farthest distance that various human individuals can feel the air conditioning blowing in an indoor space (i.e., the head of the indoor unit of the air conditioner). The first distance threshold is used to benchmark the position of human individuals in an indoor space to characterize the distance between an individual and the air conditioner.

[0087] Specifically, in step 102, the air conditioning fan speed control device can use the mapping relationship between the human-machine distance of the target human individual relative to the air conditioning indoor unit and the fan speed to calculate the target fan speed that matches the distance dimension. When doing so, it is necessary to first perform a threshold judgment on the human-machine distance of the target human individual relative to the air conditioning indoor unit.

[0088] If the distance between the target human individual and the indoor unit of the air conditioner is less than or equal to the first distance threshold, it means that the airflow distance of the air conditioner running at the current default fan speed can reach the individual's location. Then, the conversion ratio from distance to fan speed is calculated using the distance between the human and the air conditioner. Finally, the rated maximum speed of the cross-flow fan is multiplied by the conversion ratio from distance to fan speed to obtain the target fan speed.

[0089] If the distance between the target human individual and the indoor unit of the air conditioner is greater than the first distance threshold, it means that the airflow distance of the air conditioner running at the current default fan speed cannot reach the individual's location. In this case, the fan speed of the cross-flow fan will be directly increased to the rated maximum speed.

[0090] In this embodiment of the invention, when adjusting the rotational speed of a cross-flow fan based on the human-machine distance captured by a radar module for a moving individual, the target fan speed is determined by comparing the interpersonal distance and a second speed threshold. This enables adaptive adjustment of the air conditioning airflow mode based on the indoor individual's behavior in the distance dimension, improving the efficiency of indoor temperature control and optimizing the user's airflow experience.

[0091] Based on any of the above embodiments, determining the target fan speed that matches the target human individual in the speed and distance dimensions based on the moving speed of the target human individual relative to the air conditioner indoor unit and the human-machine distance includes: if it is determined that the moving speed of the target human individual relative to the air conditioner indoor unit is less than or equal to a second speed threshold, then determining a first fan speed based on the moving speed and the rated maximum speed of the cross-flow fan.

[0092] The second velocity threshold is determined based on the velocity of a human individual when displacing within an indoor space.

[0093] It should be noted that the second velocity threshold is determined based on the velocity levels of various human individuals displaced within an indoor space. The second velocity threshold is used to calibrate the instantaneous movement velocity of human individuals within an indoor space, thus characterizing the degree of individual movement.

[0094] For example, the second speed threshold and the first speed threshold can be equal.

[0095] Specifically, in step 102, when the air conditioning fan speed control device determines that the moving speed of the target human individual relative to the indoor unit of the air conditioner is less than or equal to the second speed threshold, it means that the individual's movement is not intense. Then, it calculates the conversion ratio from the movement level to the fan speed using the moving speed, and then multiplies the rated maximum speed of the cross-flow fan with the conversion ratio from the movement level to the fan speed to obtain the first fan speed.

[0096] Conversely, if the target human individual's movement speed relative to the air conditioner's indoor unit is greater than the second speed threshold, then the first fan speed is directly assigned to the rated maximum speed of the cross-flow fan.

[0097] If the distance between the target human individual and the indoor unit of the air conditioner is determined to be less than or equal to a second distance threshold, then the second fan speed is determined based on the human-machine distance and the rated maximum speed of the cross-flow fan.

[0098] The second distance threshold is determined based on the head of the indoor unit of the air conditioner.

[0099] It should be noted that the second distance threshold is determined based on the farthest distance that various human individuals can feel the air conditioning blowing in an indoor space (i.e., the head of the indoor unit of the air conditioner). The second distance threshold is used to align with the position of human individuals in an indoor space, thus characterizing the distance between an individual and the air conditioner.

[0100] For example, the second distance threshold and the first distance threshold can be equal.

[0101] Specifically, in step 102, when the air conditioning fan speed control device determines that the distance between the target human individual and the indoor unit of the air conditioner is less than or equal to the second distance threshold, that is, when the air conditioner is running at the current default fan speed, the air blowing distance can reach the location of the individual. Then, the conversion ratio from distance to fan speed is calculated using the distance between the human and the unit. Finally, the rated maximum speed of the cross-flow fan is multiplied by the conversion ratio from distance to fan speed to obtain the second fan speed.

[0102] Conversely, if the distance between the target human individual and the air conditioner indoor unit is greater than the second distance threshold, the second fan speed is directly assigned to the rated maximum speed of the cross-flow fan.

[0103] The target fan speed is determined based on the first fan speed and the second fan speed.

[0104] Specifically, the air conditioning fan speed control device can fuse the first fan speed and the second fan speed under different dimensions to obtain the target fan speed under the combined influence of the speed dimension and the distance dimension.

[0105] In this embodiment of the invention, the method of fusing fan speeds under different dimensions is not specifically limited.

[0106] For example, corresponding weight values ​​can be assigned to the different degrees of influence of the fan speed, so as to perform a weighted summation of the first fan speed and the second fan speed to obtain the target fan speed.

[0107] For example, the norms obtained from the first fan speed and the second fan speed in two dimensions can be used as the target fan speed output.

[0108] In this embodiment of the invention, when adjusting the rotational speed of a cross-flow fan in both speed and distance dimensions using radar modules to capture the movement speed and distance of a human being in motion, the target fan speed is calculated using the first and second fan speeds derived from these two dimensions. This enables adaptive adjustment of the air conditioning's airflow mode based on the indoor individual's behavior in both speed and distance dimensions, improving the efficiency of indoor temperature control and optimizing the user's airflow experience.

[0109] Based on any of the above embodiments, the formula for calculating the target fan speed is:

[0110]

[0111]

[0112]

[0113] Where n is the target fan speed; n1 is the first fan speed; v is the moving speed of the target human individual relative to the indoor unit of the air conditioner; n max The rated maximum speed of the cross-flow fan is denoted as A; a constant term is denoted as n2; the second fan speed is denoted as s; the human-machine distance between the target human individual and the indoor unit of the air conditioner is denoted as L; and the second distance threshold is denoted as L.

[0114] Specifically, the speed of the first fan calculated by the air conditioner fan speed control device in the speed dimension changes positively with the human body's movement speed; the higher the human body's movement speed, the higher the speed of the first fan. The calculation formula is as follows:

[0115]

[0116] Where n1 is the rotational speed of the first fan, and v is the moving speed of the target human individual relative to the indoor unit of the air conditioner. max This is the rated maximum speed of the cross-flow fan. A is a constant term, and the value of A is not specifically limited in this embodiment of the invention.

[0117] For example, A can be a constant value for rotational speed, such as 150.

[0118] For example, A can be the rotational speed value converted from the first speed threshold to the rotational speed. For instance, when the first speed threshold is 2 meters per second, A can be converted to 200 revolutions per second.

[0119] Next, the calculated second fan speed in the distance dimension is positively correlated with the distance between the user and the machine; the greater the distance, the higher the second fan speed. The calculation formula is as follows:

[0120]

[0121] Where n2 is the second fan speed. s is the human-machine distance between the target human individual and the indoor unit of the air conditioner. L is the second distance threshold.

[0122] Finally, the norm of the first fan speed n1 and the second fan speed n2 is calculated using the following formula:

[0123]

[0124] Where n is the target fan speed.

[0125] This invention utilizes a radar module to calculate a first fan speed matching the speed dimension based on the movement speed of a moving human individual. Then, it uses the radar module to calculate a second fan speed matching the distance dimension based on the human-machine distance captured by the moving human individual. The target fan speed is calculated using the norms of the fan speeds in both dimensions. This achieves adaptive adjustment of the air conditioning airflow mode while considering the influence of both speed and distance dimensions, improving the efficiency of indoor temperature control and optimizing the user's airflow experience.

[0126] Based on any of the above embodiments, before using the radar module to capture the moving speed and distance between the target human individual and the human, the method further includes: scanning the height of the target human individual using the radar module to determine the sway range of the sway blade assembly.

[0127] The yaw blade assembly is disposed within the cavity of the air outlet to change the output airflow direction of the cross-flow fan.

[0128] It should be noted that each air outlet cavity is equipped with a set of horizontal blade assembly, which includes multiple vertically arranged horizontal blades. By swinging the horizontal blades up and down, the output air direction of the cross-flow fan is changed to an up-and-down sweeping mode.

[0129] Specifically, before step 101, the air conditioning fan speed control device also scans the human individuals in the room from top to bottom using a radar module to obtain the radar angle corresponding to the height direction of the human body, and sets the area corresponding to the radar angle as the swing range of the sway blade assembly.

[0130] During the process of controlling the yaw blade assembly to swing up and down within the swing range, the radar module is used to capture the movement speed and distance between the target human individual and the human.

[0131] Specifically, the air conditioning fan speed control device controls the horizontal sway blade assembly to swing up and down within the obtained sway range. During the up and down sweeping process within the height range of the human body, the radar module captures the perceived position changes that occur within the cycle, so as to calculate the moving speed of the target human individual and the distance between the human and the machine.

[0132] Figure 2 This is the second flowchart illustrating the air conditioning fan speed control method provided by this invention. For example... Figure 2 As shown, a specific implementation method for air conditioner fan speed control is given:

[0133] (1) Initialize the millimeter-wave air conditioning radar to sense the radar angle corresponding to the height direction of the human body and control the horizontal guide plate assembly to swing freely within the radar angle.

[0134] (2) During the up-and-down sweeping process of the horizontal guide plate assembly, the movement speed of the human individual undergoing displacement is captured by radar:

[0135] If the moving speed is less than or equal to 2 m / s (i.e., the first speed threshold), use The first fan speed n1, which changes positively with the human body's movement speed, was calculated.

[0136] If the moving speed is greater than 2m / s (i.e., the first speed threshold), then the first fan speed n1 is directly assigned the value n. max .

[0137] (3) During the up-and-down sweeping process of the horizontal guide plate assembly, the human-machine distance of the displaced human individual is captured by radar:

[0138] If the distance between the human and the machine is less than or equal to the air conditioner head L (i.e., the first distance threshold), then utilize The second fan speed n2, which changes positively with the distance between the human and the machine, was calculated.

[0139] If the distance between the human and the machine is greater than the air conditioner head L, then the second fan speed n2 is directly assigned the value n. max .

[0140] (4) The final target fan speed of the cross-flow fan is obtained by combining the two dimensions of speed and distance:

[0141]

[0142] Where n is the target fan speed.

[0143] This invention utilizes a radar module to calculate the oscillation range of the horizontal sway blade assembly based on the height range scanned by a moving human individual. The radar module is only activated to capture the human individual's movement during the vertical oscillation process controlled by this oscillation range. This allows the air conditioner to adaptively adjust its airflow mode in both horizontal and vertical planes according to the individual's actual body posture, improving the efficiency of indoor temperature control and optimizing the user's airflow experience.

[0145] The motion capture module 310 is used to capture the moving speed and distance of the target human individual relative to the indoor unit of the air conditioner when the radar module determines that at least one human individual is in motion in the indoor space.

[0146] The fan control module 320 is used to determine the target fan speed that matches the target human individual in the speed dimension and / or distance dimension based on the moving speed and / or human-machine distance of the target human individual relative to the indoor unit of the air conditioner, so as to control the target cross-flow fan to run at the target fan speed.

[0166]

[0167]

[0168]

[0169] Where n is the target fan speed; n1 is the first fan speed; v is the moving speed of the target human individual relative to the indoor unit of the air conditioner; n max The rated maximum speed of the cross-flow fan is denoted as A; a constant term is denoted as n2; the second fan speed is denoted as s; the human-machine distance between the target human individual and the indoor unit of the air conditioner is denoted as L; and the second distance threshold is denoted as L.

[0170] Optionally, the device also includes a sway range determination and radar acquisition module, wherein:

[0171] The sway range determination is used to scan the height of the target human individual using the radar module to determine the sway range of the sway blade assembly.

[0174] The air conditioning fan speed control device provided in this embodiment of the invention is used to execute the air conditioning fan speed control method described above. Its implementation method is the same as that of the air conditioning fan speed control method provided by this invention, and it can achieve the same beneficial effects. It will not be described again here.

[0175] This invention, based on radar modules capturing the movement speed and distance of a human in motion, calculates a target fan speed that matches the human's speed and / or distance in the speed and / or distance dimensions. This allows the indoor air conditioning unit to adjust the speed of some or all of its cross-flow fans. This enables adaptive adjustment of the air conditioning's airflow mode based on the behavior of individuals indoors, improving the efficiency of indoor temperature control and optimizing the user's airflow experience.

[0176] 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 provided in this embodiment of the invention includes an indoor unit 410 and an outdoor unit 420. The indoor unit 410 is equipped with a control processor 411 and a radar module 412, with the radar module 412 disposed within the indoor unit 410. It also includes a memory and programs or instructions stored in the memory and executable on the control processor 411. When the control processor 411 executes the program or instructions, it performs the air conditioner fan speed control method described in any of the preceding embodiments.

[0178] Specifically, the air conditioner includes an indoor unit 410 and an outdoor unit 420 connected by coils, and a radar module 412 is embedded in the indoor unit 410. The control processor 411 controls the radar module 412 to collect real-time sensing location information of each individual in the space where the air conditioner is located, in order to monitor the behavior and activities of individuals in the indoor space.

[0179] If at least one individual's perceived position information changes over time during the observation period, indicating that the individual is in motion, then it is necessary to calculate the individual's instantaneous moving speed relative to the indoor air conditioner unit, as well as the straight-line human-machine distance between the individual and the indoor air conditioner unit, based on multiple sets of perceived position information of the individual during the observation period.

[0180] If the perceived position information of each individual does not change over time during the observation period, it means that all individuals are in a stationary state. In this case, it is necessary to continue to capture the movement of the individuals through the radar module until an individual is detected to have moved. Then, the individual is tracked and monitored. Based on the multiple sets of perceived position information of the individual during the observation period, the instantaneous moving speed of the individual relative to the indoor air conditioner unit and the straight-line human-machine distance between the individual and the indoor air conditioner unit are calculated.

[0181] The control processor 411 then uses the mapping relationship between the moving speed of the target human individual relative to the indoor unit of the air conditioner and the fan speed, as well as the mapping relationship between the human-machine distance of the target human individual relative to the indoor unit of the air conditioner and the fan speed, to calculate the target fan speed matched in a single dimension or multiple dimensions, and controls the target cross-flow fan matched to the position of the target human individual in the indoor space to deliver air to the zone where the individual is currently located at the target fan speed.

[0184] For example, the radar module 412 can also be embedded in the display screen of the indoor unit 410.

[0185] This invention, based on radar modules capturing the movement speed and distance of a human in motion, calculates a target fan speed that matches the human's speed and / or distance in the speed and / or distance dimensions. This allows the indoor air conditioning unit to adjust the speed of some or all of its cross-flow fans. This enables adaptive adjustment of the air conditioning's airflow mode based on the behavior of individuals indoors, improving the efficiency of indoor temperature control and optimizing the user's airflow experience.
