The invention provides an external air guide device of an air conditioner, which can be installed on the air conditioner. External air ducting includes: a motor and a transmission;
fig. 1 is a schematic structural view of a transmission according to an embodiment of the present invention. As shown in fig. 1, the transmission device includes: the motor connecting shaft 1, the transmission rod 2 and the air deflector 3; the air deflector 3 is an air deflector on an air conditioner installed on the transmission device, namely the original air deflector of the air conditioner. The air deflector 3 is rotatably connected to an air outlet of an air conditioner through a first rotating shaft, and a first end of the transmission rod 2 is pivotally connected to the air deflector 3 through a second rotating shaft 4. Specifically, the air deflector 3 has a fixing clip 41 thereon, and the fixing clip 41 of the air deflector 3 is pivotally connected to the first end of the transmission rod 2 through the second rotating shaft 4. The transmission rod 2 is connected with the motor linkage shaft 1; the motor linkage shaft 1 is connected with the motor and can rotate at any angle, and the angle of the air deflector 3 can be controlled by the driving of the motor.
Optionally, the transmission rod 2 penetrates through the motor linkage shaft 1 through an interface 5 arranged on the motor linkage shaft 1, so as to be movably connected with the motor linkage shaft 1. The transmission rod 2 is not fixedly connected with the interface 5 of the motor linkage shaft 1, but a clearance is reserved, and the transmission rod 2 can move back and forth (along the length direction).
Preferably, the external air ducting of air conditioner still includes: image acquisition device and controlling means. The image acquisition device is used for acquiring an environment image of the environment; and the control device is used for controlling the transmission device according to the environment image acquired by the image acquisition device. The image acquisition device may be, for example, a camera; the control device may be, for example, an MCU (micro processing unit). The control device is connected with the image acquisition device to control the image device to acquire the environment image; the control device is connected with the motor, and drives the motor linkage shaft 1 by controlling the motor, so that the angle of the air deflector is controlled, and the effect of adjusting the air outlet angle is achieved.

When the motor linkage shaft 1 rotates anticlockwise, the first end (the fixing clamp) of the transmission rod 2 swings leftwards, and the air deflector 3 is guided to swing leftwards. In the process of swinging from right air outlet to positive air outlet, the transmission rod 2 moves towards the outside of the paper surface relative to the motor linkage shaft 1; in the process of swinging from positive air outlet to left air outlet, the transmission rod 2 moves towards the paper surface relative to the motor linkage shaft 1.
The external air guide device of the air conditioner can be arranged on the air conditioner, for example, a cabinet air conditioner is arranged right below an air outlet and is fastened by a plastic fixing clamping belt. The hanging machine is arranged on the side surface and fixed on the wall by screws.
Fig. 2 is a block diagram of a specific implementation of the control device according to an embodiment of the invention. The control device 100 includes: an acquisition unit 110, a recognition unit 120, a determination unit 130 and a control unit 140.
The acquisition unit 110 is used for acquiring an environment image of an environment through the image acquisition device. For example, the MCU controls the image capturing device to capture an environment image of the environment in which the image capturing device is located.
The recognition unit 120 is configured to recognize recognition matrix coordinates of the user in the environment image through a cascade of files trained in advance for recognizing the user in the image.
The pre-training of the cascade files for identifying the user in the image may specifically include: acquiring an image containing an environmental background but not an identification object as a negative sample; generating an image containing a background and an identification object as a positive sample based on the negative sample; and performing haar classifier training on the positive sample through a cascade training function to obtain a cascade file for identifying the user in the image.
The negative sample is an image that includes only a background and no recognition object, and may be collected in advance, and the positive sample is an image generated by a function that includes both a background and a recognition object, which is a user, that is, a human body. Alternatively, the program of the present invention is written in python. The positive samples can be generated by OpenCV _ createsamples tool in OpenCV library, and the positive samples are direct superposition of the negative samples and the recognition objects — that is, the pictures of the recognition objects are scaled to a certain scale and then directly superposed (e.g., "pasted") on the negative samples. The present invention is not limited to the python language, as other languages are possible for writing programs and ultimately generating positive sample libraries. And then, performing haar classifier training on the positive sample through a cascade training function to obtain a cascade file for identifying the user in the image.
The recognition unit 120 may recognize the recognition matrix coordinates of the user in the environment image through the pre-trained cascade file for recognizing the user in the image. Optionally, when the control device is an MCU, the trained cascade file is stored in a memory connected to the MCU. Thus, when performing the identification of the matrix coordinates of the user, the identification unit 120 fetches the cascade file from the memory connected to the MCU to identify the matrix coordinates of the user in the captured environment image.
The determining unit 130 is configured to determine a location of the corresponding user in the environment according to the identification matrix coordinates of the users in the environment image.
The recognition matrix is the minimum matrix enveloping the recognition object after the image recognition, namely the minimum matrix containing the user, and the minimum matrix for 'framing' the user can be obtained after the recognition is successful. After the identification unit 120 identifies the identification matrix coordinates of the user, the determining unit 130 may derive the location of the user in the environment according to the identification matrix coordinates.
Fig. 3 is a flowchart of identifying matrix coordinates of a user according to an embodiment of the present invention. As shown in fig. 3, first, negative sample (negative sample) collection is performed, then, a recognition object (for example, a user image) is collected, a positive sample (positive sample) is generated according to the collected negative sample and the recognition object, the number of network layers is set, cascade training (cascade training) is performed to obtain a cascade file (cascade.
The control unit 140 is adapted to control the actuators in dependence of the determined location of the respective user in the environment.
Specifically, the control unit 140 controls the transmission device by combining the position of the user and the preset air outlet mode, so as to adjust the air outlet of the air conditioner. For example, the rotation angle of the motor linkage shaft is calculated according to the position of the user and a preset air outlet mode. Optionally, the preset air outlet mode includes a following user air outlet mode, a user air outlet avoiding mode and/or an intermittent air sweeping mode. The preset air outlet mode can be preset by a user. For example, a user sets an air outlet mode through a control panel of the external air guide device of the air conditioner.
The control unit 140 controls the driving device according to the determined position of the corresponding user in the environment, including:
(1) and under the mode of following the air outlet of the user, the air outlet direction of the air conditioner is opposite to the user by controlling the transmission device.
When more than two users exist in the environment, the air outlet direction of the air conditioner is switched between the more than two users by controlling the transmission device. For example, in the following user wind mode, the MCU (the recognition unit 120 and the determination unit 130) recognizes the user position at regular intervals, and (the control unit 140) controls the transmission such that the wind direction of the air conditioner is directed toward the user. When multiple users are present, the air deflector is controlled to swing among the multiple users.
(2) And under the mode of avoiding the air outlet of the user, controlling the transmission device to swing the air deflector in an unmanned range.
For example, in the air-out direction mode, the MCU (the identification unit 120 and the determination unit 130) identifies the position of the user at intervals, (the control unit 140) and controls the air guide plate to swing within an unmanned range so that the air-out direction of the air conditioner avoids the user.
(3) And in the intermittent wind sweeping mode, the transmission device is controlled to intermittently sweep wind for the user.
For example, when the intermittent wind sweeping mode is applied to a single user, the user position is identified, and the intermittent wind sweeping mode swings left and right within a certain angle range by taking the user position as a center. When the intermittent sweeping mode is applied to the condition of a plurality of users, the effect of the intermittent sweeping mode is similar to that of the air-out mode following the users in the condition of a plurality of users.
For example, in the intermittent wind sweeping mode, the MCU (the identification unit 120 and the determination unit 130) identifies the user position once every certain time, and the control unit 140 performs intermittent wind sweeping on the user.
Optionally, when the user moves, the identification matrix coordinates of the user also change in real time, and after the MCU identifies the change of the position of the user, the motor is controlled again, so that the rotation angle of the motor linkage shaft is changed, and the air outlet angle is adjusted in real time.
Fig. 4 is a schematic control flow diagram of an external air guiding device of an air conditioner according to an embodiment of the present invention.
As shown in fig. 4, the camera collects the environment image, the MCU analyzes the environment image collected by the camera, identifies the user in the environment, generates the position information, outputs the command to control the motor, controls the air deflector through the transmission device (mechanically drives) according to the preset air outlet mode (for example, the air outlet mode preset by the user through the control panel), and adjusts the air outlet angle to achieve the purpose of intelligent air outlet.
At present, most of air conditioners with intelligent air-out strategies on the market are a whole set of new air conditioners, that is, if a user wants to enjoy intelligent air-out, an additional new air conditioner needs to be purchased. The external air guide device of the air conditioner can be installed on the existing air conditioner without an intelligent air outlet function, and realizes intelligent air outlet with multiple air outlet modes, so that the cost of a user is greatly saved, and the external air guide device of the air conditioner has wide applicability.
The invention also provides a control method for the external air guide device of any one of the air conditioners. The control method can be implemented in the control device of the external air guide device of the air conditioner. The control device is for example an MCU (micro control unit).
Fig. 5 is a schematic method diagram illustrating an embodiment of a method for controlling an external air guiding device of an air conditioner according to the present invention.
As shown in fig. 5, according to an embodiment of the present invention, the control method includes at least step S110, step S120, step S130, and step S140.
Step S110, an environment image of the environment is acquired.
Specifically, an image acquisition device of the external air guide device of the air conditioner is used for acquiring an environment image of the environment. For example, the MCU controls the image capturing device to capture an environment image of the environment in which the image capturing device is located.
And step S120, identifying the identification matrix coordinates of the user in the environment image through a pre-trained cascade file for identifying the user in the image.
The pre-training of the cascade file for identifying the user in the image may specifically include: acquiring an image containing an environmental background but not an identification object as a negative sample; generating an image containing a background and an identification object as a positive sample based on the negative sample; and performing haar classifier training on the positive sample through a cascade training function to obtain a cascade file for identifying the user in the image.
The negative sample is an image that includes only a background and no recognition object, and may be collected in advance, and the positive sample is an image generated by a function that includes both a background and a recognition object, which is a user, that is, a human body. Alternatively, the program of the present invention is written in python. The positive samples can be generated by OpenCV _ createsamples tool in OpenCV library, and the positive samples are direct superposition of the negative samples and the recognition objects — that is, the pictures of the recognition objects are scaled to a certain scale and then directly superposed (e.g., "pasted") on the negative samples. The present invention is not limited to the python language, as other languages are possible for writing programs and ultimately generating positive sample libraries. And then, performing haar classifier training on the positive sample through a cascade training function to obtain a cascade file for identifying the user in the image.
Through the pre-trained cascade file for identifying the user in the image, the identification matrix coordinates of the user in the environment image can be identified. Optionally, when the control device is an MCU, the trained cascade file is stored in a memory connected to the MCU. Therefore, when the identification of the matrix coordinates of the user is executed, the cascade file is called from a memory connected with the MCU so as to identify the matrix coordinates of the user in the acquired environment image.
Step S130, determining the position of the corresponding user in the environment according to the identification matrix coordinates of the user in the environment image.
The recognition matrix is the minimum matrix enveloping the recognition object after the image recognition, namely the minimum matrix containing the user, and the minimum matrix for 'framing' the user can be obtained after the recognition is successful. After the identification matrix coordinates of the user are obtained through identification, the position of the user in the environment can be obtained according to the identification matrix coordinates.
And step S140, controlling the transmission device according to the determined position of the corresponding user in the environment.
Specifically, the transmission device is controlled by combining the position of the user and a preset air outlet mode, so that air outlet adjustment of the air conditioner is achieved. For example, the rotation angle of the motor linkage shaft is calculated according to the position of the user and a preset air outlet mode. Optionally, the preset air outlet mode includes a following user air outlet mode, a user air outlet avoiding mode and/or an intermittent air sweeping mode. The preset air outlet mode can be preset by a user. For example, a user sets an air outlet mode through a control panel of the external air guide device of the air conditioner.
Controlling the transmission device according to the determined position of the corresponding user in the environment, specifically, the controlling may include:
(1) and under the mode of following the air outlet of the user, the air outlet direction of the air conditioner is opposite to the user by controlling the transmission device.
When more than two users exist in the environment, the air outlet direction of the air conditioner is switched between the more than two users by controlling the transmission device. For example, in the following user wind mode, the MCU (the recognition unit 120 and the determination unit 130) recognizes the user position at regular intervals, and (the control unit 140) controls the transmission such that the wind direction of the air conditioner is directed toward the user. When multiple users are present, the air deflector is controlled to swing among the multiple users.
(2) And under the mode of avoiding the air outlet of the user, controlling the transmission device to swing the air deflector in an unmanned range.
For example, in the air-out direction mode, the MCU (the identification unit 120 and the determination unit 130) identifies the position of the user at intervals, (the control unit 140) and controls the air guide plate to swing within an unmanned range so that the air-out direction of the air conditioner avoids the user.
(3) And in the intermittent wind sweeping mode, the transmission device is controlled to intermittently sweep wind for the user.
For example, in the intermittent wind sweeping mode, the MCU (the identification unit 120 and the determination unit 130) identifies the user position once every certain time, and the control unit 140 performs intermittent wind sweeping on the user.
