Referring to fig. 2, an embodiment of a control method of an air supply system according to the present application is provided. In this embodiment, the air supply system control method includes:
step S10, when a user is not located in the coverage area of the air outlet of the air conditioner, controlling the air conditioner to supply air towards the area where the air supply device in the coverage area is located;
the coverage area of the air outlet of the air conditioner refers to the largest area covered by the air blown out from the air outlet of the air conditioner. That is, the air blown out from the air outlet of the air conditioner does not exist in other areas outside the air outlet coverage area of the air conditioner in the air supply system working space, i.e. the air outlet of the air conditioner does not blow to the current position of the user in a natural state.
The user is not located within the coverage area, i.e. the user is located outside the coverage area. Specifically, scene characteristic data (for example, scene image data, sound data, infrared detection data and the like) in a space where the air supply system is located can be collected through the detection module, whether the scene characteristic data comprises corresponding characteristic information of a user outside an air outlet coverage area of the air conditioner or not is analyzed, and if the scene characteristic data comprises the corresponding characteristic information, the user outside the air outlet coverage area of the air conditioner can be judged; if the air conditioner is not included, the user can be judged to be located in the air outlet coverage area of the air conditioner or located outside the air supply system working space. In addition, when the target user is located outside the air-conditioner air-out coverage area, the target user can also send a setting instruction to the control device by itself, when the setting instruction is detected, the target user can be considered to be located in the air-conditioner air-out coverage area, and when the setting instruction is not detected, the target user can be considered to be located outside the air-conditioner air-out coverage area. The user may be a designated user, or may be any user in the working space of the air supply system.
When the air supply device is positioned in the coverage area, the air guide component arranged at the air outlet in the air conditioner can be controlled to adjust the air guide angle so that the air outlet direction of the air conditioner faces the area where the air supply device is positioned, and the air blown out from the air outlet of the air conditioner can reach the area where the air supply device is positioned. The air supply device can be placed in the coverage area by a user, and can be controlled to move into the coverage area by a control instruction. In order to ensure the effectiveness of the air supply device in adjusting the air outlet of the air conditioner, when a user is not located in the air outlet coverage area of the air conditioner, judging whether the air supply device is located at a target position in the coverage area, and when the air supply device is located at the target position, executing the step of controlling the air conditioner to supply air towards the area where the air supply device in the coverage area is located; otherwise, a prompt message is sent to enable the user to place the air supply device at the target position or control the movable air supply device to move to the target position.
Specifically, the step of controlling the air conditioner to supply air to the area where the air supply device in the coverage area is located includes: and controlling the air conditioner to supply air towards a first target position in the coverage area. The method comprises the steps of defining a straight line where the air supply device and the air conditioner are located as a datum line, defining the straight line where the first target position and the air conditioner are located as a first straight line, wherein an included angle between the datum line and the first straight line is larger than 0, and the first target position is located in the coverage range of air outlet of the air supply device. Here, through the control of the mode to the first target position air supply of air conditioner, can make the air conditioner be the air-out of certain contained angle and blow to the coverage of air supply arrangement air-out for air supply arrangement, but not directly blow to air supply arrangement along the datum line to guarantee that the air-out of air conditioner can have abundant large area of contact with the wind that air supply arrangement blown out after reaching first target position, guarantee that more amount of wind that the air conditioner blown out can blow to the region outside the coverage area under the drive effect of air-out of air supply arrangement, thereby improve air supply arrangement to the regulation effect that enlarges the air-out scope of air conditioner. In order to further improve the adjusting effect of the air supply device, the specific size of the included angle between the datum line and the first straight line can be determined according to the air supply parameters (such as air volume, air speed and the like) of the air supply device and the air supply parameters (such as air volume, air speed and the like) of the air conditioner. The larger the air supply parameters are, the larger the included angle is, so that the air outlet of the air conditioner and the air outlet of the air supply device can be fully mixed, and the mixed air can be effectively regulated and controlled after being blown out of the coverage area.
And step S20, controlling the air supply device to supply air to the area where the user is located, so that the air outlet of the air conditioner is mixed with the air outlet of the air supply device and then is blown to the area where the user is located.
The user can be in the area by detecting the instruction input by the user (such as the air conditioner is in the living room, the user can input corresponding instructions when the user is in a dining room communicated with the living room, and the like), and the area where the user is determined based on the instruction. In addition, the area where the user is located can also be obtained according to the analysis of the scene characteristic data. For example, the location area of the user relative to the air supply device may be obtained by analysis based on data collected by a position detection module, such as an infrared module, a sound source positioning module, a camera, etc., provided on the air supply device or the air conditioner. After the area where the user is located is determined, the air outlet direction of the air supply device facing the area where the user is located is taken as a target air outlet direction, and the operation of the air guide component in the air supply device is controlled according to the target air outlet direction, so that the air blown out from the air outlet can be blown to the area where the user is located. Here, the air blown out by the air conditioner can reach the area where the user is located and then be mixed with the air outlet of the air supply device, and the mixed air is blown to the area where the user is located together under the disturbance of the air supply device on the air flow.
Besides the air outlet direction, other air outlet parameters (such as wind speed, air quantity and the like) of the air supply device can be determined according to the air outlet parameters (such as wind speed, air quantity and the like) of the air conditioner, so that the air supply device can effectively adjust the air outlet of the air conditioner.
Specifically, referring to fig. 3, the arrow indicates the direction of the air outlet, and the area within the fan-shaped dashed box indicates the area of coverage of the air outlet of the air conditioner. The air conditioner 1 and the air supply device 2 are arranged in the direction of a certain included angle to supply air to the front of the air outlet of the air supply device 2, the air blown out from the air outlet of the air supply device 2 is mixed with the air which is sent to the front of the air outlet of the air supply device 2 by the air conditioner 1, and the mixed air is blown to the region 3 of the target together under the pushing action of the air flow of the air supply device 2. The straight line a is the reference line, the straight line b is the first straight line, and the included angle alpha between the two lines a and b is more than 0 degree.
According to the air supply system control method provided by the embodiment of the application, when a user is found to be located outside the air outlet coverage area of the air conditioner, the air conditioner supplies air to the area where the air supply device located inside the air outlet coverage area of the air conditioner is located, and the air supply device supplies air to the position where the user is located, so that the air outlet of the air conditioner and the air outlet of the air supply device are mixed and then blown to the area where the user is located, the air outlet regulation and control effect of the air conditioner is not limited to the periphery of the air conditioner any more through the matched air supply of the air conditioner and the air supply device, and under the relay air supply effect of the air supply device, the regulation and control effect of the air outlet of the air conditioner on the air can be transferred to a larger range, so that the user far away from the air conditioner can obviously feel cold air or hot air, the air conditioner can regulate and control the air nearby the user rapidly, and the user comfort is improved.
Further, based on the above embodiment, another embodiment of the air supply system control method of the present application is provided. In this embodiment, referring to fig. 4, in step S10, before the step of controlling the air conditioner to supply air to the area where the air supply device in the coverage area is located, the method further includes:
step S101, when a user is not located in the coverage area of the air outlet of the air conditioner, acquiring the current air outlet parameter of the air conditioner and the position parameter of the user;
the current air outlet parameters of the air conditioner comprise the air outlet speed, the air outlet quantity and the like. The location parameter may specifically include a characteristic parameter of the location of the user relative to the air conditioner.
The current air outlet parameters of the air conditioner can be obtained by acquiring data detected by a sensor arranged in an air outlet or an air outlet duct of the air conditioner, and also can be obtained by acquiring control parameters of an air outlet regulating and controlling component (such as a fan and an air guide piece) of the air conditioner. The position parameters can be obtained by analyzing data acquired by a position detection module (such as an infrared module, a sound source positioning module, a camera and the like) arranged on the air conditioner.
Step S102, in the coverage area, determining a second target position according to the air outlet parameter and the position parameter;
different air outlet parameters and different position parameters correspond to different second target positions. Specifically, a target direction of the air supply device relative to the air conditioner and a target distance of the air supply device relative to the air conditioner can be determined according to the position parameter and the air outlet parameter, and a position corresponding to the target direction and the target distance is determined as a second target position. Specifically, the air outlet coverage area of the air conditioner can be divided into two areas based on the connection line of the air conditioner and the area where the user is located, and the area, close to the side of the area where the user is located, of the two areas is taken as the target area. In addition, different air outlet parameters correspond to different target distances. For example, the greater the wind speed or the wind output, the greater the target distance. And selecting a direction in the target area as a target direction, and taking a position which is at a target distance from the air conditioner in the target direction as a second target position. Further, the second target position can be determined by combining the air outlet parameter, the position parameter and the air supply parameter of the air supply device, and specifically, the air supply distance of the air supply device relative to the area where the user is located is determined according to the air supply parameter of the air supply device. If the wind speed or the wind quantity of the air supply parameter is larger, the air supply distance is larger, and a second target position is determined in the target area based on the air supply distance and the target distance, so that the distance between the air supply device and the air conditioner and the area where the user is located after the air supply device moves to the second target position can be the target distance and the air supply distance respectively, and the air supply device can effectively transmit the air outlet regulation and control function of the air conditioner to the area where the user is located, and the user comfort is further improved.
Step S103, judging whether the air supply device is positioned at a second target position;
if yes, step S11 is executed, and if no, step S104 is executed and then step S11 is executed.
Step S11, controlling the air conditioner to blow air towards the area where the air blowing device in the coverage area is located;
step S104, controlling the air supply device to move to the second target position.
Here, the air blowing device is specifically a movable apparatus. And sending an instruction about the second target position to the air supply device, so that the air supply device executes the instruction after receiving the instruction and moves to the second target position.
In this embodiment, because there is a certain difference in the actual air outlet coverage area of the air conditioner due to the difference in the air outlet parameters, the second target position of the air supply device in the coverage area is determined by combining the air outlet parameters of the air conditioner and the position parameters of the user, so that the air supply device is ensured to be located at the position to control the air conditioner to supply air to the air supply device, the current air outlet of the air conditioner is ensured to reach the position of the air supply device, and the effectiveness of the air supply device for transmitting the air outlet regulation and control function of the air conditioner to the position of the user is ensured, so that the rapid regulation and control of the air nearby the user are ensured, and the improvement of the user comfort is realized.
Further, based on any one of the above embodiments, another embodiment of the air supply system control method of the present application is provided. In this embodiment, referring to fig. 5, before step S10, the method further includes:
step S01, obtaining a panoramic image in an action space of an air supply system; the panoramic image includes an image of the covered area and an area outside the covered area;
the panoramic image can be generated based on image data acquired by a camera carried by the air supply system, and can also be obtained by directly acquiring the image data acquired by indoor monitoring equipment and the like outside the air supply system.
Step S02, identifying a first image corresponding to an area outside the coverage area in the panoramic image;
specifically, the scene information in the panoramic image can be identified, and when the image information corresponding to the feature object in the coverage area is identified, the area can be considered as a second image corresponding to the coverage area, and the images except the second image in the panoramic image are taken as the first image. In addition, a second image corresponding to the covered region in the panoramic image and a first image corresponding to a region other than the covered region may be identified based on a position of the panoramic image with respect to the covered region or the uncovered region.
Step S03, judging whether the first image comprises an image of a user or not;
if so, executing step S04; if the image is not included, whether a second image corresponding to the coverage area in the panoramic image includes an image of the user or not can be further identified, and if the second image includes the image of the user, the user is determined to be located in the coverage area of the air conditioner; and if the second image does not comprise the image of the user, determining that the user is positioned outside the working space of the air supply system.
When the user is a designated user, the image of the user can be acquired based on the identity information, the type and the like of the user, whether the image information matched with the acquired image exists in the first image or not is judged, and if the image information matched with the acquired image exists in the first image, the image of the user is judged to be included in the first image; if the image does not exist, the first image is judged to not include the image of the user. In addition, the user can be any user in the space, based on the user, the user can judge whether the human body is identified by carrying out human body identification on the first image, the identified human body can take the person corresponding to the human body image as the user, and the first image comprises the image of the user; and if the human body is not recognized, judging that the first image does not comprise the image of the user.
Step S04, determining that the user is not located in the coverage area.
Because the position of the user in the space is generally collected through the image module carried by the air conditioner, the shooting range of the camera is limited, and the user far away from the air conditioner cannot identify the position of the user, in the embodiment, the panoramic image of the acting space of the air supply system effectively identifies the position of the user far away from the air conditioner and located outside the air outlet coverage range of the air conditioner, so that the air supply system can adapt to the position of the remote user to timely adjust the air supply mode, the user can feel the air outlet regulation and control effect of the air conditioner even if far away from the air conditioner, and the comfort of the user is ensured.
Specifically, in this embodiment, step S01 includes:
step S011, acquiring a first scene image and a second scene image; the first scene image is collected by a first camera carried by the air conditioner, the second scene image is collected by a second camera carried by the air guiding device air supply device, the first scene image comprises an image of the coverage area of the air outlet area, and the second scene image comprises an image of an area outside the coverage area of the air outlet area;
referring to fig. 6, a region a represents an image acquisition range of a first camera, and a region B represents an image acquisition range of a second camera. The image acquisition range of the first camera can be suitable for setting the size of the coverage area of the air outlet of the air conditioner, the image acquisition range of the first camera is adopted to characterize the coverage area, and a user can be considered to be in the coverage area when the user is in the area A; the user is outside the area a, and the user can be considered to be outside the overlay user. The first camera captures all scenes within the image acquisition range to form a first scene image, and the second camera captures all scenes within the image acquisition range to form a second scene image.
In order to ensure effective and accurate splicing of the first scene image and the second scene image, the obtained panoramic image can accurately reflect the actual situation in the space, whether the air supply device is located at the set position or not can be judged before the second scene image is obtained, the air supply device is located at the set position to obtain second camera acquisition data as the second scene image, otherwise, the air supply device is controlled to move to the set position to obtain the second camera acquisition data as the second scene image. The setting position is specifically a position where the first scene image and the second scene image can have partially identical image information, that is, when the air supply position is located at the setting position, the second scene image includes an image of a partial coverage area and an image of an area other than the coverage area (for example, an image corresponding to an overlapping area D of a A, B area in fig. 6). The setting position can be determined specifically according to the image acquisition range of the first camera and the image acquisition range of the second camera. For example, in fig. 6, the position of the blower 2 is a set position, the distance between the blower 2 and the air conditioner 1 is defined as S1, the size of the image capturing range of the first camera mounted on the air conditioner 1 between the blower 2 and the air conditioner 1 is represented by the length of S2, the size of the image capturing range of the second camera mounted on the blower 2 between the blower 2 and the air conditioner 1 is represented by the length of S3, and the set position needs to satisfy S1< s2+s3.
Step S012, stitching the first scene image and the second scene image to form the panoramic image.
In this embodiment, an overlapping region having the same image information in the first scene image and the second scene image is identified; extracting first image characteristic parameters corresponding to the overlapping region from the first scene image, and extracting second image characteristic parameters corresponding to the overlapping region from the second scene image; registering the first image characteristic parameters and the second image characteristic parameters (for example, performing characteristic matching by adopting a SIFT algorithm and the like) to obtain a transformation relation; and splicing the first scene image and the second scene image based on the transformation relation to obtain the panoramic image. Here, the range of the overlapping area in the first scene image and the second scene image may be determined in combination with the relative position (e.g., the relative distance) between the air conditioner and the air supply device, the image acquisition range of the first camera (e.g., the distance from the camera to the wall), the image acquisition range of the second camera (e.g., the distance from the camera to the wall), and so on.
In other embodiments, the first scene image and the second scene image may not have overlapping areas, and the first scene image and the second scene image may be stitched by using virtually generated images based on the positions of the two cameras.
In the step S02, the image corresponding to the first scene image in the panoramic image may be used as the second image corresponding to the coverage area, and the other images except the image corresponding to the first scene image in the panoramic image may be used as the first images except the coverage area.
According to the embodiment, the panoramic image is formed by splicing the scene images collected by the air conditioner in the air supply system and the camera carried by the air supply device, so that the effective identification of the user far away from the air conditioner can be realized without the assistance of equipment outside the air supply system, and the air supply system is ensured to meet the comfort requirement of the user far away from the air conditioner.
Further, if the area outside the coverage area in the working space of the air supply system is larger, the scene image acquired by the air supply device at one position may not contain all or most of the scene information of the area outside the coverage area, based on this, in order to ensure that the actual position of the user far from the air conditioner can be accurately known, in the process of acquiring the second scene image, the air supply device can be controlled to move in the area outside the coverage area, and when the air supply device moves in the area outside the coverage area, more than one sub-image is acquired; the sub-images are images acquired by the second camera when the air supply device moves to different positions; and splicing the sub-images to form the second scene image.
In particular, the blower may be controlled to move in more than one set position outside the coverage area. One of the setting positions is a reference position, the distance between the reference position and the air conditioner needs to satisfy the relation of S1< S2+ S3, and the distance between any two adjacent setting positions can be determined by analogy with the relation of the distance between the reference position and the air conditioner. For example, the set positions include a first position, a second position, and a third position, the first position being less distant from the air conditioner than the second position. The distance between the first position and the air conditioner satisfies S1< S2+S3; the distance S4 between the second position and the first position satisfies s4< s5+s6, where S5 is the range size of the image acquisition range between the first position and the second position when the second camera mounted on the air supply device is at the first position, and S6 is the range size of the image acquisition range between the first position and the second position when the second camera mounted on the air supply device is at the second position; the distance S7 between the third position and the second position satisfies s7< s8+s9, where S8 is the range size of the image capturing range between the second position and the third position when the second camera mounted on the blower is in the second position, and S9 is the range size of the image capturing range between the second position and the third position when the second camera mounted on the blower is in the third position. And when the air supply device moves to each set position, acquiring image data acquired by the second camera to obtain a sub-image. The sub-images may be spliced by analogy with reference to the above-mentioned manner of splicing between the first scene image and the second scene image, which is not described herein.
