[0002] As people's living standards continue to improve, their standards for quality of life are also rising, and air conditioners have become an indispensable household appliance. Current air conditioners generally use temperature sensors, humidity sensors, and infrared sensors to detect the environment or people in the room, determining whether someone is in the room and whether the temperature distribution is uniform, thereby adjusting the operating mode or airflow accordingly.
[0003] However, infrared sensors can only detect the presence or movement of a human body, but cannot accurately identify the body's location and movement status. They are also easily affected by obstructions, making them unsuitable for complex home environments. Millimeter-wave radar, with its high sensitivity, strong anti-obstruction capabilities, and micro-motion detection advantages, is gradually being applied to the sensing and control of smart homes. In the air conditioning field, its initial functions are mostly focused on "occupant / unoccupied" detection and basic anti-direct-blow airflow, such as switching the airflow direction when a person is detected approaching; the comfort of the airflow still needs improvement.

[0017] Please see Figure 1 , Figure 1 This is a flowchart illustrating an air supply control method for an air conditioner according to an embodiment of the present invention. The air supply control method for the air conditioner will be described in detail below. Figure 1 As shown, the method includes the following steps S110-S120.
[0018] S110. Obtain human activity status information, and perform human status recognition based on the human activity status information to obtain human status recognition result. In this embodiment of the invention, human activity status information is acquired, including personnel information, number of personnel, distance to the human body, azimuth angle of the human body, and speed of the human body. Specifically, a millimeter-wave radar module is used to acquire the human activity status information. The millimeter-wave radar module mainly consists of three parts: a radio frequency front-end, a signal processing unit, and an antenna array. The radio frequency front-end adopts monolithic microwave integrated circuit technology and integrates core components such as a voltage-controlled oscillator, a phase-locked loop, a power amplifier, a low-noise amplifier, and a mixer, operating in the 24GHz or 77GHz frequency band. The antenna array adopts a multi-transmitter, multi-receiver configuration, forming a spatial array through multiple receiving antennas to provide phase difference information for angle measurement. The signal processing unit, based on a high-performance microcontroller or a dedicated digital signal processor, is responsible for digital processing and algorithm calculation of the echo signal.
[0019] It should be noted that in this embodiment, the measurement of human body distance is based on Frequency Modulated Continuous Wave (FMCW) technology. The millimeter-wave radar module transmits a millimeter-wave signal (chirp signal) with a frequency that varies linearly with time. When the signal encounters a human body, it is reflected back. The transmitted and received signals are mixed by a mixer to generate an intermediate frequency (IF) signal (difference frequency signal). The frequency of the IF signal is proportional to the distance. By analyzing the spectrum of this signal using Fast Fourier Transform (FFT), the distance d between the human body and the millimeter-wave radar module can be calculated, which is the human body distance.
[0020] The azimuth angle of the human body is calculated using the phase difference principle of a multi-receiver antenna array. When a millimeter-wave signal arrives at multiple receiving antennas from different directions, the echo signal will generate a phase difference due to the spatial position difference between the antennas. By calculating the phase difference Δφ between different receiving antennas on the same distance unit, and combining it with the operating wavelength λ and the antenna spacing Δd, the azimuth angle θ of the human body can be calculated according to formula (1). Understandably, the more antennas there are, the higher the angular resolution.
[0021] (1) The calculation process of human body velocity is as follows: When the human body moves relative to the millimeter-wave radar module, the frequency of the reflected echo will generate a Doppler frequency shift f_D, which is proportional to the human body velocity v. By performing FFT processing on the echo signal of multiple Chirp cycles along the slow time dimension on a fixed distance cell, the Doppler frequency f_D is obtained, and the human body velocity v can be calculated according to formula (2).
[0022] (2) It should also be noted that in this embodiment, personnel information and the number of personnel can be obtained through point cloud clustering algorithms. The millimeter-wave radar module has all-weather operation capability, unaffected by environmental factors such as light, temperature, and smoke. It can penetrate non-metallic materials such as clothing and curtains for detection, while not collecting any image information, fundamentally protecting user privacy. The module is small in size and has low power consumption, making it suitable for embedded installation. In this embodiment, the millimeter-wave radar module is installed above the air outlet, with a tilt angle set at 2–8° to balance coverage range and avoid airflow interference.
[0023] In this embodiment, such as Figure 2 As shown, step S110 specifically includes steps S111-S113: S111. Set the personnel status to unmanned or manned based on the personnel information; S112. Set the human body's operating state to a moving state or a stationary state according to the human body's speed; S113. Set the orientation of the human body according to the human body azimuth angle.
[0024] In this embodiment of the invention, the human body state recognition result includes the person's state, the person's running state, and the person's orientation. Specifically, step S113 includes: if the absolute value of the person's orientation angle is not greater than a first orientation angle threshold, then the person's orientation is set to the front of the person; if the absolute value of the person's orientation angle is greater than the first orientation angle threshold and less than a second orientation angle threshold, then the person's orientation is set to the side of the person; if the absolute value of the person's orientation angle is not less than the second orientation angle threshold, then the person's orientation is set to the back of the person. It should be noted that, in this embodiment, if the person information indicates the presence of a person, then the person's state is set to a present state; if the person information indicates the absence of a person, then the person's state is set to an unoccupied state; if the person's speed is greater than or equal to a preset speed, then the person's running state is set to a moving state; if the person's speed is less than the preset speed, then the person's running state is set to a stationary state. It should also be noted that in this embodiment, the first orientation angle threshold is 30° and the second orientation angle threshold is 150°. Understandably, assuming the human body orientation angle is θ, if |θ|≤30°, the human body orientation is set to the front of the human body; if |θ|≥150°, the human body orientation is set to the back of the human body; if 30°<|θ|<150°, the human body orientation is set to the side of the human body.
[0025] S120. Generate air supply control parameters based on the human body state recognition result and the human body activity state information, and control the air conditioner to adjust the air supply according to the air supply control parameters.
[0026] In this embodiment of the invention, the air supply control parameters include the operating mode, the offset angle of the air guide angle, and the wind speed; such as Figure 3 As shown, step S120 specifically includes steps S121-S122: S121, if the personnel status is "unmanned" and the duration of the unmanned status is not less than a preset duration, then the operating mode is set to energy-saving mode and the wind speed is set to low speed; S122, if the personnel status is "manned", then the offset angle of the air guide angle and the wind speed are set according to the number of personnel, the distance between the human bodies, the orientation of the human bodies, and the movement state of the human bodies. Specifically, when the personnel status is determined to be "unmanned", a delayed energy-saving mechanism will be activated. The duration of the unmanned status is recorded. If the duration is less than the preset duration (e.g., 3-5 minutes), the existing air supply mode is temporarily maintained to prevent frequent mode switching caused by the short-term departure of personnel; if the duration of the unmanned status reaches or exceeds the preset duration, it is confirmed to be unmanned, the operating mode is set to energy-saving mode, and the wind speed is adjusted to low speed (e.g., 1.0 m / s). At the same time, the air guide plate can be controlled to return to the center position to maintain basic air circulation and reduce energy consumption. When the personnel status is determined to be "manned", the personalized comfort air supply control logic is entered. The air supply control parameters are set based on the comprehensive real-time acquisition of multi-dimensional human activity status information.
[0027] In one embodiment, such as this embodiment, as Figure 4As shown, step S122 specifically includes steps S1221-S1225: S1221, if the human body's movement state is the stationary state, then the human body distance is compared with a preset distance interval, wherein the preset distance interval includes a first preset distance interval, a second preset distance interval, and a third preset distance interval; S1222, if the human body distance is within the first preset distance interval and the human body is facing forward, then the offset angle of the wind guide angle is set to a first angle offset interval, and the wind speed is set to a first preset wind speed interval; S1223, if the human body distance is within the second preset distance interval and the human body is facing sideways, then... S1224. If the distance of the human body is within the first preset distance range and the human body is facing away from the body, then the offset angle of the wind guide angle is set to the third angle offset range and the wind speed is set to the third preset wind speed range; S1225. If the human body is in a moving state and there are multiple people, then a weight is calculated based on the human body speed and the detected dwell time of each moving person, and the offset angle of the wind guide angle is set to point towards the moving person with the largest weight, and the wind speed is set to a reduced preset wind speed value. Specifically, when the human body is stationary, the offset angle of the wind guide angle is set based on the comparison result between the human body distance and the preset distance range, combined with the human body orientation information. Specifically, the preset distance range is usually divided into three ranges: the first preset distance range (e.g., 0-1.5 meters), the second preset distance range (e.g., 1.5-3.0 meters), and the third preset distance range (e.g., above 3.0 meters). If the distance to the person is within the first preset distance range and the person is facing forward, the guide angle is set to the first angle offset range (e.g., +15 to +20°) to direct the cold air upwards toward the ceiling, avoiding direct airflow onto the person. Simultaneously, the wind speed is set to the first preset wind speed range (e.g., 1.0-1.5 m / s). If the distance to the person is within the second preset distance range and the person is facing to the side, the guide angle is set to the second angle offset range (e.g., +5 to +10°) to achieve lateral airflow, and the wind speed is set to the second preset wind speed range (e.g., 1.5-2.0 m / s). If the distance to the person is within the first preset distance range and the person is facing backwards, the guide angle is set to the third angle offset range (e.g., 0° to -5°) to direct the cold air downwards toward the ground, achieving indirect airflow through ground reflection, and the wind speed is set to the third preset wind speed range (e.g., 0.8-1.2 m / s).
[0028] Furthermore, if the human body is in a moving state and multiple people are detected, the air delivery weight for each moving person is calculated. The weight calculation is based on the human body's speed *v* and the detected dwell time *t*, typically using the weighted formula *w_i = a·v_i + b·t_i*, where *a* and *b* are weighting coefficients (e.g., *a* = 0.3, *b* = 0.7). The air guide angle is set to point towards the moving person with the highest weight, ensuring the primary user receives the best air delivery effect. Simultaneously, considering that the human body's airflow demand is relatively low during movement, the wind speed is reduced by a preset value (e.g., by 1-2 fan speeds) to avoid discomfort caused by excessive airflow. This dynamic weight allocation mechanism achieves an intelligent air delivery effect that "follows the person's movement," prioritizing the primary user's needs in multi-user scenarios while also considering the comfort of other users, effectively improving the accuracy and comfort of the air conditioning's air delivery.
[0029] It should be noted that, in this embodiment, for ease of understanding, Figure 5 It shows the air supply path when people are stationary and when they are moving. Figure 6 This demonstrates that occupied area A receives priority air supply, while unoccupied area receives low-speed air supply. Figure 7 It demonstrates the relationship between the distance to the human body, wind speed, and the offset angle of the wind guide angle.
[0030] Figure 8 A flowchart illustrating an air supply control method for an air conditioner according to another embodiment of the present invention is shown below. Figure 8 As shown, in this embodiment, the method includes steps S110-S130. That is, in this embodiment, the method further includes step S130 after step S120 in the above embodiment.
[0031] S130. Collect actual air supply parameters, compare the actual air supply parameters with the air supply control parameters to obtain a comparison result, and correct the air supply adjustment of the air conditioner according to the comparison result.
[0032] In this embodiment of the invention, the feedback correction mechanism is a key element in ensuring the accuracy and comfort of air supply in the air conditioning air supply control system. This mechanism continuously compares the actual air supply parameters (such as the actual air supply angle of the air guide vane and the actual wind speed of the fan) monitored by sensors in real time with the air supply control parameters (including air supply angle and wind speed) generated by the main control module to obtain a comparison result (i.e., a deviation value). Corrections are then made based on the comparison result. For example, if the deviation between the actual air supply angle and the actual air supply angle exceeds a preset threshold (e.g., 2°), or the wind speed deviation exceeds a preset wind speed deviation value (e.g., 0.3 m / s), a correction signal is generated. This signal drives the actuators (such as the servo motor of the air guide vane and the speed controller of the fan) to make fine adjustments, gradually reducing the gap between the actual air supply parameters and the air supply control parameters.
[0033] It should be noted that in this embodiment, during the air supply adjustment process, by setting a hysteresis range for state judgment (e.g., the distance d between the human body entering the gentle breeze mode is <1.3 meters, and the distance d between the human body exiting the gentle breeze mode is >1.7 meters) and by limiting the speed of the actuator's action rate (e.g., the angular velocity of the air guide plate is ≤3° / s), frequent jumps or sudden changes in air supply mode, air direction, and wind speed near the critical point are effectively avoided. This ensures smooth air direction conversion and gentle wind speed changes, fundamentally eliminating the discomfort and noise caused by frequent adjustments or overshooting actions, providing users with a stable, quiet, and comfortable environment. Mechanical limits and overcurrent protection can directly prevent hardware damage; when the radar signal sent by the millimeter-wave radar module is continuously abnormal, it automatically switches to a safe mode (air guide plate returns to center, wind speed is reduced), ensuring that the air conditioner can still operate in the most conservative and safest way when the sensing fails, greatly reducing the risk of misjudgment or malfunction. It should also be noted that in this embodiment, the air conditioner is also equipped with a night mode. In night mode, by limiting the maximum operating parameters (such as fan speed), the number of times the motor starts and stops and runs at high speed is actively reduced. This not only directly reduces nighttime energy consumption, but more importantly, it significantly reduces the noise generated by mechanical movements, avoiding disturbing the user's sleep and achieving a balance between energy saving and quiet operation.

[0037] In some embodiments, such as this one, the generation control unit 202 is specifically used for: If the personnel status is the unmanned status and the duration of the unmanned status is not less than the preset duration, then the operating mode is set to energy-saving mode and the wind speed is set to low speed. If the personnel status is "occupied", then the offset angle of the wind guide angle and the wind speed are set according to the number of personnel, the distance between the human bodies, the orientation of the human bodies, and the movement status of the human bodies.
[0038] In some embodiments, such as this one, the generation control unit 202 is further configured to: If the human body is in the stationary state, the distance between the human body and a preset distance interval is compared with the preset distance interval, wherein the preset distance interval includes a first preset distance interval, a second preset distance interval, and a third preset distance interval.
