Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning equipment, and in particular to an air conditioning wind speed control method, device and air conditioner. Background Art

[0002] Air conditioners are essential equipment in indoor places. They can provide users with a comfortable living or working environment by controlling the indoor ambient temperature.

[0003] In the prior art, air conditioners usually use built-in centrifugal fans or cross-flow fans for blowing. The wind pressure of centrifugal fans is relatively large. When the air conditioner uses the built-in centrifugal fans for blowing, the blowing distance is relatively far, but the user's blowing feeling is strong, and the user's comfort experience is not good. Therefore, cross-flow fans with lower wind pressure are usually selected. Since the wind pressure is lower, the blowing distance is relatively short, which weakens the user's blowing feeling to a certain extent. In addition, the wind speed of traditional air conditioners is usually fixed, and in actual scenarios, the fixed wind speed air supply often does not match the behavior of individuals indoors, making it difficult to achieve the best temperature control effect, resulting in low efficiency in controlling the indoor ambient temperature. Summary of the invention

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments.

For example, the first object can be one or more.

[0047] It should be understood that the terms used in the present specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in the present invention, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0049] Figure 1 FIG. 1 is one of the flow charts of the air conditioning wind speed control method provided by the present invention. Figure 1 As shown, the air conditioning wind speed control method provided by the embodiment of the present invention is applied to an air conditioning indoor unit having an air supply device and multiple air outlets; the air supply device includes multiple cross-flow fans, each cross-flow fan corresponds to an air outlet, and the control method includes: step 101, when it is determined by a radar module that there is at least one human individual in motion in the indoor space, using the radar module to capture the moving speed and human-machine distance of the target human individual.

[0050] Wherein, the radar module is arranged in the indoor unit of the air conditioner. The target human individual is a human individual in motion in the indoor space.

[0051] It should be noted that the execution subject of the air conditioner wind speed control method provided in the embodiment of the present invention is an air conditioner wind speed control device.

[0052] The application scenario of the air conditioning wind speed control method provided by the embodiment of the present invention is that when the user activates the air conditioner, the movement posture of the individual when the individual is displaced relative to the air conditioning indoor unit is determined through the sensor data fed back in real time by the radar module, and the speed of one or more fans in the air supply device is adjusted so that the air supply after the adjusted wind speed matches the movement posture of the individual indoors.

[0053] The radar module periodically collects displacement information of all individuals in the room at specified time intervals, and sends the displacement information to the air conditioner wind speed control device. The embodiment of the present invention does not specifically limit the working cycle of the radar module.

[0054] Optionally, the radar module can perform collection operations in a default working cycle.

[0055] Optionally, the user can issue a cycle change instruction so that the radar module receives and responds to the instruction and changes the working cycle to the cycle indicated by the instruction to perform collection operations.

[0056] It should be noted that before step 101, the user needs to send an activation instruction through a transmission medium to activate the working mode of the air conditioner, so that the indoor unit of the air conditioner runs each cross-flow fan at the default wind speed of the mode, and the outdoor unit runs at the default frequency of the mode.

[0057] Optionally, the user can use the control device to transmit activation instructions through wireless communication between the control device and the air-conditioning system, so that the air-conditioning system initializes the working mode and starts the radar module.

[0058] Optionally, the user can issue an activation command through 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 the working mode, the air conditioner wind speed control device receives the real-time sensing position information collected by the radar module for each individual in the space where the air conditioner is located, to monitor the behavior of human individuals in the indoor space:

[0060] If the perceived position information of at least one individual changes over time during the observation period, it means that the individual is in motion. It is necessary to calculate the instantaneous moving speed of the individual relative to the air-conditioning indoor unit and the straight-line human-machine distance between the individual and the air-conditioning indoor 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 with time during the observation period, that is, all individuals are in a stationary state, it is necessary to continue to capture the movement of the individuals through the radar module until an individual is detected to have moved, and then track and monitor the individual. 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 air-conditioning indoor unit and the straight-line human-machine distance between the individual and the air-conditioning indoor unit are calculated.

[0062] The embodiment of the present invention does not specifically limit the type and quantity of radar sensing devices in the radar module.

[0063] Exemplarily, the radar module may include a laser radar, an infrared sensor, etc.

[0064] Optionally, since the horizontal detection range of the millimeter-wave radar can reach ±75°, the vertical detection range can reach ±40°, the maximum detection distance can reach 8 meters, the distance output accuracy can reach 0.1 meters, the angle output accuracy can reach 1°, and it does not involve privacy issues, is not affected by light, and its response speed is also faster.

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

[0066] Exemplarily, the radar module may include multiple sensor elements such as millimeter wave radar, lidar, infrared sensor, etc. The air-conditioning wind speed control device integrates the behavioral information collected by each sensor element to comprehensively depict the individual's real-time perception position.

[0067] Step 102: Based on the moving speed of the target human individual relative to the air-conditioning indoor unit and / or the human-machine distance, determine a target fan speed that matches the target human individual in the speed dimension and / or the distance dimension, so as to control the target crossflow fan to operate 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, and the air supply area of ​​the air conditioner indoor unit can be divided into multiple partitions according to the arrangement positions of the k air outlets.

[0070] For example, for a wall-mounted air conditioner with the indoor unit of the air conditioner fixed on the wall, the number of lateral distribution of air outlets is much larger than the number of longitudinal distribution, so the lateral distribution of the air outlets can be divided into multiple partitions vertically. When the target human individual walks to a certain partition, the cross-flow fan behind the air outlet corresponding to the partition can be used as the target cross-flow fan.

[0071] For example, if the indoor unit of the air conditioner is a cabinet-type air conditioner placed on the ground, the number of longitudinally distributed air outlets is much larger than the number of lateral distributions, so the lateral distribution of the air outlets can only divide into limited areas. When the target human individual is horizontally displaced relative to the indoor unit of the air conditioner, all cross-flow fans can be used as target cross-flow fans.

[0072] Specifically, in step 102, the air conditioning wind speed control device can use the mapping relationship between the moving speed of the target human individual relative to the air conditioning indoor unit and the fan speed, as well as 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 convert the target fan speed that matches in a single dimension or multiple dimensions, and control the target crossflow fan that matches the position of the target human individual in the indoor space to supply air to the partition where the individual is currently located at the target fan speed. Fan speeds other than the target fan speed can be maintained at the default speed value of the activated working mode.

[0073] It is understandable that after the target fan speed is calculated, all cross-flow fans may be operated at the target fan speed to increase the temperature regulation efficiency.

[0074] The embodiment of the present invention converts the target fan speed that matches the human individual in the speed dimension and / or distance dimension based on the movement speed and human-machine distance captured by the radar module of the human individual in motion, so as to adjust the speed of part or all of the crossflow fans of the air conditioner indoor unit. The air supply mode of the air conditioner can be adaptively adjusted according to the behavior and activities of the indoor individual, the control efficiency of the indoor ambient temperature can be improved, and the user's blowing experience can be optimized.

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

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

[0077] The first speed threshold is determined according to the speed at which a human individual moves in an indoor space.

[0078] It should be noted that the first speed threshold is determined according to the speed level of displacement of various human individuals in the indoor space. The first speed threshold is used to benchmark the instantaneous movement speed of human individuals in the indoor space to characterize the degree of movement of the individuals.

[0079] Specifically, in step 102, the air conditioner wind speed control device can use the mapping relationship between the moving speed of the target human individual relative to the air conditioner indoor unit and the fan speed to convert the target fan speed matched in the speed dimension. It is necessary to first perform a threshold judgment on the moving speed of the target human individual relative to the air conditioner indoor unit:

[0080] If the moving speed of the target human individual relative to the air-conditioning indoor unit is less than or equal to the first speed threshold, which means that the individual's exercise level is not intense, the moving speed is used to calculate the conversion ratio from the exercise level to the fan speed, and then the rated maximum speed of the cross-flow fan is multiplied by the conversion ratio from the exercise level to the fan speed to obtain the target fan speed.

[0081] If the moving speed of the target human individual relative to the indoor unit of the air conditioner is greater than the first speed threshold, which means that the individual's movement level is relatively intense, the wind speed of the cross-flow fan is directly increased to the rated maximum speed.

[0082] In the embodiment of the present invention, when the speed of the crossflow fan is adjusted in the speed dimension by using the moving speed captured by the radar module of the human individual in motion, the value of the target fan speed is determined by comparing the moving speed with the first speed threshold. The air-conditioning air supply mode is adaptively adjusted according to the behavior of the indoor individual in the speed dimension, the control efficiency of the indoor ambient temperature is improved, and the user's blowing experience is optimized.

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

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

[0085] The first distance threshold is determined according to the lift 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 at which various types of human individuals feel the air blowing of the air conditioner in the indoor space (i.e., determined by the head of the indoor unit of the air conditioner). The first distance threshold is used to benchmark the position of the human individual in the indoor space to represent the distance of the individual from the air conditioner.

[0087] Specifically, in step 102, the air conditioner wind speed control device can use the mapping relationship between the human-machine distance of the target human individual relative to the air conditioner indoor unit and the fan speed to convert the target fan speed matched in the distance dimension. It is necessary to first perform a threshold judgment on the human-machine distance of the target human individual relative to the air conditioner indoor unit:

[0088] If the human-machine distance of the target human individual relative to the air-conditioning indoor unit is less than or equal to the first distance threshold, it means that the air blowing distance when the air conditioner is running at the current default wind speed can radiate to the individual's location. Then, after using the human-machine distance to convert the conversion ratio from the distance to the fan speed, the rated maximum speed of the cross-flow fan is multiplied by the conversion ratio from the distance to the fan speed to obtain the target fan speed.

[0089] If the human-machine distance of the target human individual relative to the air-conditioning indoor unit is greater than the first distance threshold, which means that the air blowing distance of the air conditioner when running at the current default wind speed cannot radiate to the individual's location, the wind speed of the cross-flow fan is directly increased to the rated maximum speed.

[0090] In the embodiment of the present invention, when the radar module is used to capture the human-machine distance of a moving human individual to adjust the speed of the crossflow fan in the distance dimension, the target fan speed value is determined by comparing the interpersonal distance with the second speed threshold. The air supply mode of the air conditioner is adaptively adjusted according to the behavior of the indoor individual in the distance dimension, the control efficiency of the indoor ambient temperature is improved, and the user's blowing experience is optimized.

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

[0092] The second speed threshold is determined according to the speed at which a human individual moves in an indoor space.

[0093] It should be noted that the second speed threshold is determined according to the speed level of displacement of various human individuals in the indoor space. The second speed threshold is used to benchmark the instantaneous movement speed of human individuals in the indoor space to characterize the degree of movement of the individuals.

[0094] Exemplarily, the second speed threshold and the first speed threshold may be equal in value.

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

[0096] On the contrary, if the moving speed of the target human individual relative to the air-conditioning indoor unit is greater than the second speed threshold, the first fan speed is directly assigned to the rated maximum speed of the cross-flow fan.

[0097] When it is determined that the human-machine distance of the target human individual relative to the air-conditioning indoor unit is less than or equal to a second distance threshold, a second fan speed is determined based on the human-machine distance and a rated maximum speed of the cross-flow fan.

[0098] The second distance threshold is determined according to the lift 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 at which various types of human individuals feel the air blowing of the air conditioner in the indoor space (i.e., determined by the head of the indoor unit of the air conditioner). The second distance threshold is used to benchmark the position of the human individual in the indoor space to represent the distance of the individual from the air conditioner.

[0100] Exemplarily, the second distance threshold and the first distance threshold may be equal in value.

[0101] Specifically, in step 102, the air conditioning wind speed control device determines that the human-machine distance of the target human individual relative to the air conditioning indoor unit is less than or equal to the second distance threshold, which means that the blowing distance when the air conditioner is running at the current default wind speed can radiate to the individual's location. Then, after using the human-machine distance to convert the conversion ratio from the degree of distance to the fan speed, the rated maximum speed of the cross-flow fan is multiplied by the conversion ratio from the degree of distance to the fan speed to obtain the second fan speed.

[0102] On the contrary, if the human-machine distance of the target human individual relative to the air-conditioning 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 wind speed control device can fuse the first fan speed and the second fan speed in different dimensions to obtain a target fan speed under the influence of the speed dimension and the distance dimension.

[0105] The embodiment of the present invention does not specifically limit the method for fusing the fan speeds in different dimensions.

[0106] Exemplarily, corresponding weight values ​​may be allocated according to different degrees of influence on the fan speeds, so as to perform a weighted summation on the first fan speed and the second fan speed to obtain a target fan speed.

[0107] Exemplarily, the norms of the first fan speed and the second fan speed in two dimensions may be output as the target fan speed.

[0108] In the embodiment of the present invention, when the radar module is used to capture the moving speed and the human-machine distance of a moving human individual to adjust the speed of the crossflow fan in the speed dimension and the distance dimension respectively, the target fan speed is calculated by the first fan speed and the second fan speed converted in the two dimensions. The air supply mode of the air conditioner is adaptively adjusted according to the behavior activities of the indoor individual in the speed dimension and the distance dimension, the control efficiency of the indoor ambient temperature is improved, and the user's blowing experience is optimized.

[0109] Based on any of the above embodiments, the target fan speed is calculated as follows:

[0110]

[0111]

[0112]

[0113] Wherein, 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 air conditioner indoor unit; n max is the rated maximum speed of the cross-flow fan; A is a constant term; n2 is the second fan speed; s is the human-machine distance of the target human individual relative to the air-conditioning indoor unit; and L is the second distance threshold.

[0114] Specifically, the first fan speed in the speed dimension calculated by the air conditioning wind speed control device changes in a positive correlation with the human body movement speed. The higher the human body movement speed, the higher the first fan speed. The calculation formula is as follows:

[0115]

[0116] Wherein, n1 is the first fan speed. v is the moving speed of the target human individual relative to the air conditioner indoor unit. max is the rated maximum speed of the cross-flow fan. A is a constant term, and the embodiment of the present invention does not specifically limit the value of A.

[0117] Exemplarily, A may be a speed constant value, for example, A may be 150.

[0118] Exemplarily, A may be a rotation speed value converted from the first speed threshold to the rotation speed. For example, when the first speed threshold is 2 meters per second, A may be converted to 200 revolutions per second accordingly.

[0119] Next, the calculated second fan speed in the distance dimension changes in a positive correlation with the human-machine distance. The farther the human-machine distance is, the higher the second fan speed is. The calculation formula is as follows:

[0120]

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

[0122] Finally, the norm of the first fan speed n1 and the second fan speed n2 is calculated, and the calculation formula is as follows:

[0123]

[0124] Wherein, n is the target fan speed.

[0125] The embodiment of the present invention uses the radar module to convert the moving speed of a human individual in motion into a first fan speed that matches the speed dimension, and then uses the radar module to convert the human-machine distance of the human individual in motion into a second fan speed that matches the distance dimension, and calculates the target fan speed through the norm of the fan speed in the two dimensions. This achieves the effect of both the speed dimension and the distance dimension when adaptively adjusting the air supply mode of the air conditioner, improves the control efficiency of the indoor ambient temperature, and optimizes the user's blowing experience.

[0126] Based on any of the above embodiments, before using the radar module to capture the moving speed and human-machine distance of the target human individual, it also includes: scanning the height of the target human individual through the radar module to determine the swing range of the swing blade assembly.

[0127] Wherein, the swing blade assembly is arranged in the cavity of the air outlet to change the output wind direction of the cross-flow fan.

[0128] It should be noted that a group of horizontal swing blade assemblies are arranged in the accommodating cavity of each air outlet. The horizontal swing blade assembly includes a plurality of vertically arranged horizontal blades. The output wind direction of the cross-flow fan is changed to an up and down sweeping mode by the up and down swinging of the horizontal blades.

[0129] Specifically, before step 101, the air conditioning wind speed control device also uses a radar module to scan the human individuals in the room up and down to obtain the radar angle corresponding to the height direction of the sensing human body, and sets the area range corresponding to the radar angle as the swing range of the swing blade assembly.

[0130] In the process of controlling the lateral swing blade assembly to swing up and down within the wind swing range, the radar module is used to capture the moving speed of the target human individual and the distance between the human and the machine;

[0131] Specifically, the air conditioning wind speed control device controls the swing blade assembly to swing up and down within the obtained swing wind range. During the process of sweeping the wind up and down within the human height range, the radar module is used to capture the perceived position changes that occur within the cycle to calculate the movement speed and human-machine distance of the displaced target human individual.

[0132] Figure 2 FIG. 2 is a flow chart of the air conditioning wind speed control method provided by the present invention. Figure 2 As shown, a specific implementation method of an air conditioning wind speed control method is given:

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

[0134] (2) During the process of the cross-guide assembly sweeping up and down, the moving speed of the human individual that is displaced is captured by radar:

[0135] If the moving speed is less than or equal to 2m / s (i.e. the first speed threshold), use A first fan speed n1 that changes in positive correlation with the moving speed of the human body is calculated.

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

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

[0138] If the human-machine distance is less than or equal to the air conditioning head L (i.e., the first distance threshold), use A second fan speed n2 that changes in positive correlation with the human-machine distance is calculated.

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

[0140] (4) The final target fan speed of the crossflow fan is obtained by converting the two dimensions of speed and distance:

[0141]

[0142] Wherein, n is the target fan speed.

[0143] The embodiment of the present invention uses the radar module to convert the height range scanned by the human individual in motion into the swing range of the horizontal swing blade assembly, and activates the radar module to capture the movement of the human individual only when the horizontal swing blade assembly is controlled to sweep up and down using the swing range. The air supply mode of the air conditioner in the horizontal and vertical planes can be adaptively adjusted according to the actual body shape of the individual, thereby improving the control efficiency of the indoor ambient temperature and optimizing the user's blowing experience.

Figure 3 As shown, the air conditioner wind speed control device provided by the embodiment of the present invention includes a motion capture module 310 and a fan control module 320, wherein:

[0145] The motion capture module 310 is used to capture the moving speed and human-machine distance of the target human individual relative to the indoor unit of the air conditioner by using the radar module when it is determined through the radar module that there is at least one human individual in motion in the indoor space.

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

[0147] Among them, the radar module is arranged in the indoor unit of the air conditioner; the target human individual is a human individual in motion in the indoor space; and the target crossflow fan is a crossflow fan that matches the position of the target human individual in the indoor space.

[0148] Specifically, the motion capture module 310 and the fan control module 320 are electrically connected in sequence.

[0149] The motion capture module 310 receives the real-time sensing position information collected by the radar module for each individual in the air-conditioning space, and monitors the behavior of the individual in the indoor space:

[0150] If the perceived position information of at least one individual changes over time during the observation period, it means that the individual is in motion. It is necessary to calculate the instantaneous moving speed of the individual relative to the air-conditioning indoor unit and the straight-line human-machine distance between the individual and the air-conditioning indoor unit based on multiple sets of perceived position information of the individual during the observation period.

[0159] The first distance threshold is determined according to the lift of the indoor unit of the air conditioner.

[0160] Optionally, the fan control module 320 includes a first speed determining unit, a second speed determining unit and a third speed determining unit, wherein:

[0161] The first speed determination unit is used to determine a first fan speed based on the moving speed and the rated maximum speed of the cross-flow fan when it is determined that the moving speed of the target human individual relative to the air-conditioning indoor unit is less than or equal to a second speed threshold.

[0162] The second speed determination unit is used to determine the second fan speed based on the human-machine distance and the rated maximum speed of the cross-flow fan when it is determined that the human-machine distance of the target human individual relative to the air-conditioning indoor unit is less than or equal to a second distance threshold.

[0163] The third rotation speed determining unit is configured to determine the target fan rotation speed based on the first fan rotation speed and the second fan rotation speed.

[0164] The second speed threshold is determined according to the speed of a human individual when moving in the indoor space; and the second distance threshold is determined according to the lift of the indoor unit of the air conditioner.

[0165] Optionally, the target fan speed is calculated as follows:

[0166]

[0167]

[0168]

[0169] Wherein, 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 air conditioner indoor unit; n max is the rated maximum speed of the cross-flow fan; A is a constant term; n2 is the second fan speed; s is the human-machine distance of the target human individual relative to the air-conditioning indoor unit; and L is the second distance threshold.

[0170] Optionally, the device further comprises a wind swing range determination and radar capture module, wherein:

[0171] The wind swing range is determined to scan the height of the target human individual through the radar module to determine the wind swing range of the swing leaf assembly.

[0172] The radar capture module is used to capture the moving speed and human-machine distance of the target human individual by using the radar module during the process of controlling the lateral swing blade assembly to swing up and down within the wind swing range.

[0173] Wherein, the swing blade assembly is arranged in the cavity of the air outlet to change the output wind direction of the cross-flow fan.

[0174] The air conditioning wind speed control device provided in an embodiment of the present invention is used to execute the above-mentioned air conditioning wind speed control method of the present invention. Its implementation method is consistent with the implementation method of the air conditioning wind speed control method provided by the present invention, and can achieve the same beneficial effects, which will not be repeated here.

[0175] The embodiment of the present invention converts the target fan speed that matches the human individual in the speed dimension and / or distance dimension based on the movement speed and human-machine distance captured by the radar module of the human individual in motion, so as to adjust the speed of part or all of the crossflow fans of the air conditioner indoor unit.

[0176] Figure 4 Schematic diagram of the structure of the air conditioner provided by the present invention. Figure 4 As shown, the air conditioner provided in the embodiment of the present invention includes an indoor unit 410 and an outdoor unit 420, wherein the indoor unit 410 is provided with a control processor 411 and a radar module 412, and the radar module 412 is provided in the indoor unit 410.

The control processor 411 controls the radar module 412 to collect real-time sensing position information of each individual in the space where the air conditioner is located, so as to monitor the behavior activities of human individuals in the indoor space:

[0179] If the perceived position information of at least one individual changes over time during the observation period, it means that the individual is in motion. It is necessary to calculate the instantaneous moving speed of the individual relative to the air-conditioning indoor unit and the straight-line human-machine distance between the individual and the air-conditioning indoor 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 with time during the observation period, that is, all individuals are in a stationary state, it is necessary to continue to capture the movement of the individuals through the radar module until an individual is detected to have moved, and then track and monitor the individual. 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 air-conditioning indoor unit and the straight-line human-machine distance between the individual and the air-conditioning indoor unit are calculated.

[0181] The control processor 411 then uses the mapping relationship between the movement speed of the target human individual relative to the air-conditioning indoor unit and the fan speed, as well as 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 convert the target fan speed that matches in a single dimension or multiple dimensions, and controls the target cross-flow fan that matches the position of the target human individual in the indoor space to supply air to the partition where the individual is currently located at the target fan speed. Fan speeds other than the target fan speed can be maintained at the default speed value of the activated working mode.

[0185] The embodiment of the present invention converts the target fan speed that matches the human individual in the speed dimension and / or distance dimension based on the movement speed and human-machine distance captured by the radar module of the human individual in motion, so as to adjust the speed of part or all of the crossflow fans of the air conditioner indoor unit.
