TECHNICAL FIELD

[0001] The present application relates to the field of air conditioning technology, in particular to a control method of a guide vane structure, a guide vane structure and an air conditioner. BACKGROUND

[0002] The prior art vertical air conditioner cannot identify and locate the static or dynamic target (such as the position of the human body) in the air supply area of the air conditioner when automatically supplying air, resulting in blind air supply direction and often causing cold air or hot air to directly blow on the target. Directly blowing cold air on the human body will cause discomfort, such as headache, joint pain, etc.; directly blowing hot air on the human body will cause dry skin, a burning sensation, and other adverse experiences. This not only reduces user comfort, but also may have a potential impact on health.

[0003] The infrared pyroelectric sensor (PIR) or the single-function camera scheme used in the prior art vertical air conditioner has three major core shortcomings due to its inherent technical limitations: (1) Low detection accuracy, unable to reliably identify stationary users and difficult to obtain accurate coordinate information of the human body; (2) Single function, lack of continuous tracking ability for multiple target dynamic human bodies, unable to provide data support for precise air supply; (3) Rough control strategy, only macroscopic direction deflection can be achieved, unable to generate and execute an optimal air supply path that can accurately bypass the human body, resulting in limited user experience improvement.

[0004] The core technical problem to be solved by the present application is how to enable the vertical air conditioner to real-time and accurately identify and track the target position in the air supply area, and intelligently control the movement of the air blade to automatically avoid direct blowing on the target, achieve comfortable air supply effect, and at the same time ensure effective regulation of indoor temperature.

[0032] The following will be described in detail Figure 1 A control method of an air deflector structure is described. The control method of the air deflector structure comprises the following steps: S1, acquiring an image and determining a preset target; S2, dividing the image into a plurality of air supply areas; S3, identifying the preset target in the plurality of air supply areas, and determining the air supply area where the preset target is located as a target area, and excluding the target area from the plurality of air supply areas to form a designated air supply area; S4, controlling the swing angle of the air deflector body 1 to match the designated air supply area.

[0033] Specifically, in step S1, the image of the area in front of the air conditioner is acquired by the image acquisition module 2, which preferably adopts a camera, which can be one or more, installed on the top of the air conditioner and / or the middle of the air conditioner. The preset target is specified by human, which can be a person, a pet or a computer case, etc. The preset target is confirmed by image recognition technology, and the swing of the air deflector body 1 is controlled based on the mapping algorithm of the control instruction recognized by the image recognition technology.

[0034] It can be understood that, in order to ensure real-time tracking of the target for air supply, in step S1, real-time image acquisition can be used to realize real-time control of the air deflector body 1 to track the target for blowing, which has the tracking function.

[0035] The mapping algorithm from image recognition to control instruction can be summarized in four steps: 1) image acquisition and preprocessing (mainly involving steps S1 and S3); 2) target detection and pixel coordinate extraction (mainly involving steps S2 and S3); 3) mapping of image pixel coordinates to world coordinates (mainly involving steps S2 and S3); 4) calculation of world coordinates to deflector steering angle (mainly involving step S4).

[0036] First step: image acquisition and target detection (from image to pixel coordinate) Image acquisition: a wide-angle camera integrated on the top of the air conditioner acquires RGB images at a fixed frame rate.

[0037] Preprocessing: the image is preprocessed as follows: distortion correction: correct the image edge distortion caused by the wide-angle lens to ensure coordinate accuracy; white balance / brightness normalization: improve the recognition robustness under different lighting conditions.

[0038] Target detection and pixel coordinate extraction: the present application adopts a lightweight deep learning target detection algorithm based on the YOLO (You Only Look Once) v5 / v7-tiny architecture. Taking the preset target as a human body as an example, the algorithm is optimized and trained for this specific target. After the algorithm infers each frame of image, it will output the bounding box of all detected human bodies in the image; the pixel coordinates (u, v) of the bottom center point of each human body bounding box are taken as the key point representing the position of the human body (the reason for choosing the bottom center point is that it is closest to the foot position of the human body, which can most accurately reflect the projection point of the human body on the ground).

[0039] Example: assuming the image resolution is 1920 1080, the algorithm detects a person, and the pixel coordinates of the bottom center point of the bounding box are (u, v) = (800, 900).

[0040] Second step: coordinate system definition and unification In order to realize accurate mapping, three coordinate systems need to be defined first, and their conversion relationship is determined through calibration.

[0041] Image pixel coordinate system (O p -uv): the origin O p (0,0) is at the top left corner of the image, the u-axis is to the right, and the v-axis is downward. This is the coordinate system for obtaining the human body coordinates (u, v). Camera coordinate system (O c -XYZ): the origin O c is the optical center of the camera; the Z-axis coincides with the optical axis and points forward; the X and Y axes are parallel to the u and v axes of the image coordinate system. World coordinate system (O w- XYZ): To simplify the calculation, the world coordinate system is unified with the air conditioner body; the definition is as follows: the origin O w Set the center point of the air conditioner outlet plane; the Z axis is parallel to the ground and points to the front of the air conditioner; the X axis is parallel to the ground and points to the left side of the air conditioner; the Y axis is perpendicular to the ground and points upward. The rotation angle of the deflector can be directly defined in this world coordinate system.

[0042] Third step: mapping of image pixel coordinates to world coordinates (core conversion) This conversion needs to be completed through camera calibration. Calibration is a one-time, pre-manufacturing step to determine the camera's intrinsic matrix K and extrinsic matrix [R|t].

[0043] 1. Camera intrinsic matrix K: describes the imaging geometry characteristics inside the camera, including focal length (f x ,f y ) and principal point coordinates (C x ,C y ). Obtained by calibration board calibration.

[0044] 3. Coordinate conversion formula: Pixel coordinates (u, v) are converted to world coordinates (X w , Y w , Z w ), which is a 2D to 3D conversion that requires a constraint condition. Make a reasonable assumption: people stand on the ground, that is, the Y w =0 of the foot point of the human body (because the world origin is at the height of the air conditioner outlet, the ground height is a known negative value, for simplicity, Y w =0 can be translated to make the ground Y w =0).

[0045] The conversion process mainly includes two steps: conversion from image pixel coordinates (u, v) to coordinates in the camera coordinate system (X c , Y c , Z c ); conversion from the camera coordinate system to the world coordinate system (X w , Y w , Z w ).

[0046] Pixel coordinates to camera coordinates (direction) conversion formula: [X c , Y c , Z c ] ^ T = Z c where K is the intrinsic matrix of the camera, containing the focal length and principal point; intrinsic matrix K is a 3x3 upper triangular matrix. This formula converts pixel coordinates (u, v) to a ray in the camera coordinate system, whose direction is represented by (X c ,Y c ,Z c ), but at this time Z c is unknown. In fact, a normalized direction vector is obtained, but further conversion to the world coordinate system is required.

[0047] The conversion formula from camera coordinates to world coordinates: [X c ,Y c ,Z c ,1] ^ In the formula, [R|t] is the extrinsic matrix of the camera, where R is a 3x3 rotation matrix and t is a 3x1 translation vector. This formula converts a point (X w ,Y w ,Z w ) in the world coordinate system to the camera coordinate system.

[0048] Since the height of the ground in the world coordinate system is known (i.e. Y w = 0, here it is assumed that the origin of the world coordinate system is at the air outlet, and the ground height is negative, but the ground can be made Y w = 0 by translation), the two conversions can be combined and the constraint Y w = 0 can be used to solve for X w and Z w in the world coordinate system.

[0049] Fourth step: calculation of the deflector turning angle from the world coordinates; after obtaining the world coordinates X w ,Z w , the horizontal deflection angle θ is calculated: θ = arctan(X w / Z w ).

[0050] The final calculated target angle θ will be converted to the number of pulses required by the stepper motor. For example: a commonly used stepper motor requires one pulse per 1.8°, so the number of pulses required for the rotation angle θ is Pulses = θ / 1.8. The main controller (MCU) drives the horizontal stepper motor to rotate accurately to θ by outputting PWM pulses of a specific number and frequency.

[0051] Through the above mapping algorithm, the swing angle of the deflector body 1 can be accurately adjusted.

[0052] Specifically, in step S2, the acquired image is divided into multiple air supply areas by image segmentation processing technology, and the number of air supply areas can be designed based on the environment and / or the configuration of the air conditioner. In this embodiment, the air conditioner is a vertical air conditioner, and the image is divided into four air supply areas in the horizontal direction, i.e., the leftmost, left, right, and rightmost air supply areas.

[0053] Specifically, in step S3, the preset target is identified in the four air supply areas by image recognition technology, and the air supply area where the preset target is located is determined as a target area. The target area is excluded from the multiple air supply areas to form a designated air supply area. If there is no preset target in the four air supply areas, the original air supply mode is maintained (generally not closed to avoid condensation of the guide plate); if there is a preset target in the four air supply areas, the guide vane body 1 is opened with a small opening degree and outputs soft wind to ensure that the airflow avoids directly blowing on the user. In this step, the air supply area where the preset target is identified is defined as the target area, the target area is excluded from the air supply area, and the remaining area is defined as the designated air supply area. The designated air supply area contains the preset target, and air is supplied in the designated air supply area to avoid directly blowing on the preset target.

[0054] Specifically, in step S4, the swing angle of the guide vane body 1 is adjusted according to the determined designated air supply area, and the angle of the guide vane body 1 is adjusted to avoid the air conditioner wind directly blowing on the preset target.

[0055] The control method of the guide vane structure provided by the present application comprises the following steps: S1, acquiring an image and determining a preset target; S2, dividing the image into multiple air supply areas; S3, identifying the preset target in the multiple air supply areas, and determining the air supply area where the preset target is located as a target area. The target area is excluded from the multiple air supply areas to form a designated air supply area; S4, controlling the swing angle of the guide vane body 1 to match the designated air supply area. The control method of the guide vane structure provided by the present application acquires the image in front of the air conditioner, divides the image into multiple air supply areas, detects the preset target in the multiple air supply areas, excludes the target area where the preset target is located from the air supply area to form a designated air supply area, and controls the guide vane body 1 to swing to the designated air supply area to avoid directly blowing wind on the specific target. The present application dynamically calculates and performs the avoidance action (such as stopping, deflecting, and finding the optimal air supply path) of the guide vane based on real-time visual information, realizes the active and accurate "wind avoiding people blowing" comfortable effect, fundamentally eliminates the phenomenon of cold and hot wind directly blowing on the human body, and improves the user experience.

[0056] In one of the embodiments of the present application, the S3 specifically comprises: determining the designated air supply area as an area far away from the target area. In this embodiment, air is supplied in the air supply area far away from the preset target, preferably, in order to avoid supplying air to the preset target, air is supplied to the area farthest from the air supply area where the preset target is located in principle.

[0057] In one of the embodiments of the present application, the S3 specifically comprises: if the air supply area where the preset target is located covers the whole air supply area, the S4 specifically comprises: controlling the air deflector body 1 to swing to the minimum opening position.

[0058] In the above embodiment, if the preset target appears in the whole air supply area, direct blowing cannot be completely avoided by excluding the air supply mode of the preset target, therefore, the swing angle of the air deflector body 1 is opened to the minimum, so that the direct blowing of the air flow to the preset target is reduced to the maximum in the soft air mode.

[0059] In one of the embodiments of the present application, the S2 specifically comprises: S21, dividing the image into a plurality of horizontally arranged air supply areas; and the S4 specifically comprises: S41, dividing the swing area of the air deflector body 1 into a plurality of horizontally arranged swing angles, and controlling the swing angle of the air deflector body 1 to match the designated air supply area.

[0060] In the above embodiment, the step S21 divides the image into a plurality of horizontally arranged air supply areas, which is particularly suitable for adjusting the air direction of the vertical air conditioner, and has good effect on avoiding direct blowing when the preset target is located at different horizontal positions; for the side air outlet mode of the vertical air conditioner, the step S41 can ensure that the air deflector body 1 accurately swings into the air supply area without the preset target.

[0061] In one of the embodiments of the present application, the S41 specifically comprises: S411, controlling the swing angle of the air deflector body 1 far away from the target area to match the designated air supply area; and S412, controlling the air deflector body 1 close to the target area to swing to the minimum opening position.

[0062] In the above embodiment, in step S411, the specified air supply area is the area not containing the preset target, and the air supply to the specified air supply area is achieved by controlling the swing angle of the air deflector body 1 away from the target area; in step S412, the swing angle of the air deflector body 1 close to the target area is controlled to open to the minimum, so as to reduce the direct blowing of the air flow to the preset target. For example, the preset target appears in the leftmost air supply area of the image, and according to the above embodiment, it is determined that the air supply area away from the leftmost end is the specified air supply area, that is, the rightmost air supply area is the actual air supply area after determination, the right air deflector body 1 is controlled to open to the opening degree matching the actual air supply area (which can be the opening degree of blowing to the right side and the rightmost side), and the left air deflector body 1 is controlled to open to the minimum opening degree. In the above embodiment, the air deflector body 1 close to the target area is not closed and opens to the minimum opening degree position, which on the one hand reduces the direct blowing of the air flow to the preset target, and on the other hand avoids the condensation of the air deflector body 1. Different swing control logics are designed for the air deflector bodies located at different positions in this embodiment, so as to accurately control the air flow to avoid direct blowing.

[0063] In one of the embodiments of the present application, the S41 specifically includes: if the target area involves multiple continuous air supply areas and is close to multiple air deflector bodies 1 at the same time, the multiple air deflector bodies 1 close to the target area are controlled to swing to the maximum opening degree position, so as to form a surrounding air around the target area.

[0064] In the above embodiment, if the preset target involves multiple continuous air supply areas and is close to multiple air deflector bodies 1 at the same time, the multiple air deflector bodies 1 are controlled to open to the maximum opening degree, so as to form a surrounding air around the target area, thereby effectively avoiding the direct blowing to the preset target. For example, the preset target appears in the left and right areas of the image, and it is determined that the leftmost and rightmost ends are the specified air supply areas, and the left and right air deflector bodies 1 are controlled to open to the maximum opening degree, so as to form a surrounding air around the preset target and avoid the direct blowing to the preset target. For another example, the preset target appears in the leftmost, left and right areas of the image, which involves three continuous air supply areas, but is mainly close to the left air deflector body 1, therefore, the swing angle of the right air deflector body 1 is controlled to match the specified air supply area, and the left air deflector body 1 is controlled to swing to the minimum opening degree position. In this embodiment, in order to reduce the direct blowing effect when there are multiple preset targets, the swing angle of the air deflector body is adjusted to form a surrounding air around the target.

[0065] In one of the embodiments of the present application, the S41 specifically comprises: matching the swing angle of the air deflector body 1 in the horizontal direction to the specified air supply area, and matching the swing angle of the air deflector body 1 in the height direction to the horizontal or the minimum opening position. This embodiment mainly relates to the horizontal swing air deflector adjustment, and is particularly suitable for the left and right air outlet vertical air conditioner. It should be understood that the swing angle of the air deflector body 1 is matched to the specified air supply area, which means that the air deflector body 1 should be adjusted to adjust the air direction to the specified air supply area, and one or more air deflector bodies 1 need to be adjusted to the specified air supply area for multiple preset targets to avoid direct blowing to the preset target as much as possible. For the air deflector adjustment in the height direction, the adjustment is also carried out according to the principle of avoiding direct blowing to the preset target, and the minimum opening degree is opened to avoid frost.

[0066] In one of the embodiments of the present application, the S2 specifically comprises: dividing the image into four horizontally arranged air supply areas. The S4 specifically comprises: dividing the swing area of the air deflector body 1 into first, second, third, fourth and fifth swing angles arranged horizontally, and the angle value ranges of the first, second, third, fourth and fifth swing angles from the closed position of the air deflector are 15°-25°, 25°-35°, 50°-60°, 90°-100° and 100°-110°, respectively. Preferably, the first, second, third, fourth and fifth swing angles from the closed position of the air deflector are 20°, 30°, 55°, 95° and 105°, respectively, and the maximum opening angle is 108°.

[0067] In one of the embodiments of the present application, the S3 specifically comprises: pre-processing the obtained image, and determining the air supply area where the preset target is located and the specified air supply area through a target detection algorithm; and the S4 specifically comprises: S401, establishing the coordinate system of the obtained image and the coordinate system of the air conditioner; S402, corresponding the coordinate system of the image to the coordinate system of the air conditioner, and mapping the image coordinates to the coordinate system of the air conditioner; and S403, adjusting the swing angle of the air deflector body 1 according to the position of the specified air supply area in the coordinate system of the air conditioner. This embodiment provides a mapping algorithm from image recognition to control instruction, and realizes accurate adjustment of the swing angle of the air deflector body.

[0068] In the above embodiments, the image preprocessing and target detection algorithm in step S3 are described in detail in the first step of the image recognition to control command mapping algorithm above; steps S401 to S403 have been described in detail in the second to fourth steps of the image recognition to control command mapping algorithm above (S401 and S402 correspond to the second and third steps, and S403 corresponds to the fourth step), and will not be repeated here.

[0069] This invention provides a specific control method for an air guide plate structure, using a vertical air conditioner, such as...
