According to the scheme, the air conditioner is provided with the voice acquisition device, the air conditioner determines the position information of the user in the space where the air conditioner is located relative to the air conditioner, and therefore the sensitivity of the voice acquisition device is adjusted according to the position information; the larger the direct distance between the user and the air conditioner is, the higher the sensitivity of the voice acquisition device is, and the larger the angle between the direction of the user relative to the air conditioner and the voice acquisition direction of the voice acquisition device is, the higher the sensitivity is, so that the air conditioner can clearly capture the voice instruction sent by the user, and the accuracy of the voice recognition of the air conditioner is higher.
Based on the hardware architecture of the air conditioner, the embodiment of the control method of the air conditioner is provided.
Referring to fig. 2, fig. 2 is a first embodiment of a control method of an air conditioner according to the present invention, the control method of the air conditioner including the steps of:
step S10, determining the position information of a user relative to the air conditioner in the space where the air conditioner is located, wherein the position information comprises at least one of the distance between the user and the air conditioner and the direction of the user relative to the air conditioner;
in the present invention, the execution body is an air conditioner. The air conditioner is provided with a voice acquisition device which can be a microphone, and the sensitivity of voice recognition of the voice acquisition device is adjustable.
The air conditioner may determine location information of an indoor user relative to the air conditioner, the location information including a distance between the user and the air conditioner and a direction of the user relative to the air conditioner. The air conditioner can be provided with an infrared distance measuring device, and the air conditioner acquires the position information of the user relative to the air conditioner through an infrared distance measuring module.
The air conditioner can also be provided with an image acquisition device, the air conditioner acquires the position information of a user relative to the air conditioner through the image acquisition device, and the image acquisition device can be a camera. Specifically, when the user appears in the visual field of the image acquisition device, the image acquisition device acquires the image of the user, the frame of the head of the user is marked according to the image, and the distance and the angle between the user and the air conditioner can be calculated according to the position and the size of the frame of the head, wherein the angle is the included angle between the direction of the user relative to the air conditioner and the forward direction of the air conditioner. Referring to fig. 3, a bounding box is a square frame of the head of the user and has coordinates (x, y, w, h), where x, y are x-y coordinates of the target object (the target object is the head of the user) in the picture, and w, h are the length and width of the target object. According to the coordinates of the target object and the size information of the picture, the distance and the angle information of the target object from the air conditioner can be calculated, wherein the angle is calculated in the counter-clockwise direction of the depression angle, and the formula is as follows: angle 135- (x/w) × 90; x is the x-axis distance of the target object, w is the width of the picture, and the range of the visible angle is 45-135 degrees. The distance calculation formula is that x is 1/x; y ═ a × x + b; where a is the weight, b is the offset, and x is the width of the target object.
Step S20, adjusting the sensitivity of the voice collecting device according to the position information, wherein the distance and the sensitivity are in positive correlation, and the included angle between the direction of the user relative to the air conditioner and the voice collecting direction of the voice collecting device and the sensitivity are in positive correlation.
After the air conditioner determines the position information, the sensitivity of the voice collecting device can be adjusted according to the position information. Specifically, when the location information is a distance between the user and the air conditioner, the air conditioner determines the sensitivity according to the distance, a mapping relationship between the distance and the sensitivity, and the sensitivity is higher when the distance is larger. For example, at a distance of 1m, the sensitivity of the voice capture device is-44 dB; when the distance is 2m, the sensitivity of the voice acquisition device is-41 dB; when the distance is 3m, the sensitivity of the voice acquisition device is-38 dB; when the distance is 4m, the sensitivity of the voice acquisition device is-35 dB; at a distance of 5m, the sensitivity of the voice acquisition device is-32 dB.
When the position information is the direction of the user relative to the air conditioner, the direction is defined as the user direction, the air conditioner determines that the included angle between the user direction and the voice collecting direction of the voice collecting device is larger, and the sensitivity of the voice collecting device is larger. Of course, the sensitivity of the voice collecting device can also be directly determined by the distance and the direction of the user. For example, the distance between the user and the air conditioner is 2m, and if the included angle α between the user direction and the voice acquisition direction of the voice acquisition device is 0, the sensitivity is-41 dB; if alpha is 30 degrees, the sensitivity is-40 dB; if alpha is 60 degrees, the sensitivity is-38 dB; and if the alpha is 180 degrees, the sensitivity is the maximum sensitivity of the voice acquisition device.
It should be noted that the above is only an exemplary enumeration of the numerical relationship between the distance and the sensitivity, and the numerical relationship between α and the sensitivity, and those skilled in the art can flexibly set the sensitivity of the voice collecting device according to actual situations.
After the sensitivity of the voice acquisition device is adjusted, if a voice instruction sent by a user is detected, the air conditioner executes operation corresponding to the voice instruction.
In the technical scheme provided by the embodiment, the air conditioner is provided with a voice acquisition device, and the air conditioner determines the position information of a user in the space where the air conditioner is located relative to the air conditioner, so that the sensitivity of the voice acquisition device is adjusted according to the position information; the larger the direct distance between the user and the air conditioner is, the higher the sensitivity of the voice acquisition device is, and the larger the angle between the direction of the user relative to the air conditioner and the voice acquisition direction of the voice acquisition device is, the higher the sensitivity is, so that the air conditioner can clearly capture the voice instruction sent by the user, and the accuracy of the voice recognition of the air conditioner is higher.
Referring to fig. 4, fig. 4 is a second embodiment of the control method of the air conditioner according to the present invention, and based on the first embodiment, after step S10, the method further includes:
and step S30, controlling the rotation mechanism to rotate according to the position information so that the voice collecting surface of the voice collecting device faces the user, wherein the position information comprises the direction of the user relative to the air conditioner.
In this embodiment, the air conditioner is provided with a rotating mechanism connected with the voice collecting device, and the rotating mechanism can be a motor. The air conditioner controls the rotation of the voice acquisition surface of the voice acquisition device through the rotating structure. After the air conditioner determines the direction of a user relative to the air conditioner, namely the direction of the user, the direction of the user and the voice collecting direction of the voice collecting surface of the voice collecting device are determined, an included angle between the direction of the user and the voice collecting direction is further determined, and the rotating angle of the rotating mechanism can be determined according to the included angle.
After the rotation angle is determined, the motor can be controlled to rotate, so that the voice acquisition surface of the voice acquisition device faces the user, and voice information sent by the user is acquired.
It should be noted that after the voice collecting device is rotated, the sensitivity of the voice collecting device is only adjusted according to the distance between the user and the air conditioner.
In the technical scheme provided by the embodiment, the air conditioner controls the voice acquisition surface of the voice acquisition device to face the user according to the direction of the user relative to the air conditioner, and simultaneously adjusts the sensitivity of the voice acquisition device according to the distance between the user and the air conditioner, so that the voice instruction sent by the user can be more clearly captured.
Referring to fig. 5, fig. 5 is a third embodiment of the control method of the air conditioner according to the present invention, and based on the first or second embodiment, the step S20 includes:
step S21, determining the identity of the user and determining the habit volume value of the user according to the identity;
and step S22, adjusting the sensitivity of the voice acquisition device according to the habitual volume value and the position information.
In the present embodiment, images of the respective members in the family are stored in the air conditioner. The air conditioner collects the user image through the image collecting device, and further determines the identity of the user according to the stored image and the collected image. The air conditioner collects the sound of each member in a family and the volume of the sound in real time, and then habit volume information of each member is determined, wherein the habit volume information refers to a normal volume value in daily life of a user; of course, the air conditioner can directly record the volume of each member in the family, and then the recorded volume is used as the habitual volume.
The greater the habitual volume value, the less sensitive the voice capture device may be. And after the air conditioner determines the sensitivity of the voice acquisition device according to the position information, the air conditioner further corrects the determined sensitivity according to the habitual volume value, wherein the corrected sensitivity is the final sensitivity of the voice acquisition device. The air conditioner may calculate a difference between the habitual volume of the user and the preset volume, and decrease the determined sensitivity if the difference is a positive value, and increase the determined sensitivity if the difference is a negative value. For example, the distance between the user and the air conditioner is 1m, the sensitivity of the voice collecting device is-44 dB, and the preset volume is 25dB (decibel), if the habitual volume value of the user is 30dB, the sensitivity is reduced, and the reduced sensitivity is-45 dB.
In the technical scheme provided by this embodiment, the air conditioner determines the identity of the user, determines the habit volume information of the user according to the identity of the user, and then determines the sensitivity of the voice acquisition device according to the habit volume information and the position information, so that the air conditioner combines the volume condition of the user, flexibly sets the sensitivity of the voice acquisition device, and the intelligent degree of the air conditioner is high.
Referring to fig. 6, fig. 6 is a fourth embodiment of the control method of the air conditioner according to the present invention, and based on the first or second embodiment, the step S20 includes:
step S23, acquiring the user image acquired by the image acquisition device;
step S24, determining an included angle between the face orientation direction of the user and the voice acquisition direction of the voice acquisition device according to the image;
and step S25, adjusting the sensitivity of the voice acquisition device according to the included angle and the position information.
In the present embodiment, the air conditioner is provided with an image pickup device. After the air conditioner obtains the user image collected by the image collecting device, the air conditioner can determine the included angle between the face orientation direction of the user and the voice collecting direction of the voice collecting device according to the user image. Since the face orientation direction of the user represents the orientation direction of the mouth of the user, the greater the included angle between the face orientation direction and the voice collection direction of the voice collection device, the more blurred the voice of the user collected by the voice collection device. In this regard, after determining the sensitivity of the voice collecting device according to the position information, the air conditioner corrects the determined sensitivity according to an included angle between the face orientation direction of the user and the voice collecting direction of the voice collecting device, wherein the larger the included angle is, the larger the correction value is, and the correction value is positive. For example, the distance between the user and the air conditioner is 1m, the sensitivity of the voice collecting device is-44 dB, if the angle beta between the face-facing direction and the voice collecting direction of the voice collecting device is 0, the sensitivity is-44 dB, if beta is 30 degrees, the determined sensitivity is increased by-44 dB, and the increased sensitivity is-42 dB.
In the technical scheme provided by this embodiment, the air conditioner acquires the user image acquired by the image acquisition module, so as to determine an included angle between the face orientation direction of the user and the voice acquisition direction of the voice acquisition device according to the user image, and correct the sensitivity of the voice acquisition device determined by the position information according to the included angle, so that the air conditioner flexibly sets the sensitivity of the voice acquisition device according to the orientation of the mouth of the user relative to the air conditioner.
Referring to fig. 7, fig. 7 is a fifth embodiment of the control method of the air conditioner according to the present invention, and based on the first or second embodiment, the step S20 includes:
step S26, determining the environmental noise value of the position of the user;
and step S27, adjusting the sensitivity of the voice acquisition device according to the environment noise value and the position information.
In the present embodiment, the air conditioner is provided with an acoustic camera and an image pickup device. The air conditioner can determine the position of the user after acquiring the user image acquired by the image acquisition device, and the air conditioner controls the acoustic camera to calculate the environmental noise value of the position of the user, wherein the environmental noise value refers to the sound size except the user, for example, the position of the user contains a plurality of other users, and the other users are noise sources. When the air conditioner collects the environmental noise of the position where the user is located, prompt information can be output to enable the user to be in a silent state.
After the air conditioner determines the sensitivity of the voice acquisition device according to the position information, the determined sensitivity can be corrected according to the environmental noise value. The larger the value of the environmental noise is, the larger the noise at the position where the user is located is, and therefore, the sensitivity of the voice collecting device needs to be increased, that is, the value of the environmental noise is proportional to the correction value. For example, the distance between the user and the air conditioner is 1m, the sensitivity of the voice collecting device is-44 dB, if the value of the environmental noise is 20dB, the determined sensitivity is increased by-44 dB, and the increased sensitivity is-40 dB.
In the technical scheme provided by this embodiment, the air conditioner determines the environmental noise value of the location where the user is located, and corrects the sensitivity of the voice acquisition device determined by the location information according to the environmental noise value, so that the air conditioner flexibly sets the sensitivity of the voice acquisition device according to the environmental noise.
Referring to fig. 8, fig. 8 is a sixth embodiment of a method for controlling an air conditioner according to the present invention, and based on any one of the first to fifth embodiments, the method further includes:
step S40, acquiring the position of an environment noise source, and generating position suggestion information of voice output according to the position of the environment noise, wherein the position corresponding to the position suggestion information is different from the position of the environment noise;
and step S50, outputting the position suggestion information to allow the user to output a voice instruction at a position corresponding to the position suggestion information.
In the present embodiment, the air conditioner is provided with an acoustic camera. The air conditioner determines the location of each of the environmental noise sources in the room through the acoustic camera. For example, a family holds a birthday meeting, and there are multiple entertainment locations in the room, each of which may be considered an ambient noise source. When the noise value of the environmental noise source is larger than the preset noise value, and the user is in the environmental noise source, the air conditioner cannot accurately capture the voice command sent by the user. In this regard, after acquiring the position of the environmental noise source, the air conditioner generates position suggestion information of voice output according to the position of the environmental noise source, the position corresponding to the position suggestion information is different from the position of the environmental noise source, and the air conditioner outputs the position suggestion information so that the user can output a voice instruction at the position corresponding to the position suggestion information.
The air conditioner may display the position suggestion information in the form of an image, and specifically, the air conditioner may display positions corresponding to the sources of the environmental noise on the display screen, and the positions may be marked with red dots. The air conditioner can display a blue area, wherein the blue area is a position corresponding to the position suggestion information, namely the position suggestion information. To facilitate user understanding, a description of the red dot location and the blue area may be displayed on the display screen.
In the technical scheme provided by this embodiment, the air conditioner acquires the position of the ambient noise source, generates the position suggestion information of the voice output according to the position of the ambient noise source, and outputs the position suggestion information so that the user can output the voice instruction at the position corresponding to the position suggestion information, thereby enabling the air conditioner to clearly capture the voice instruction.
Referring to fig. 9, fig. 9 is a seventh embodiment of the control method of the air conditioner according to the present invention, and based on any one of the first to sixth embodiments, the step S10 includes:
step S11, when the target information is detected, obtaining location information of the user corresponding to the target information relative to the air conditioner, where the target information includes at least one of a preset action and a preset voice.
There may be a plurality of users in the space where the air conditioner is located. The air conditioner needs to determine a target user, and the sensitivity of the voice acquisition device is adjusted according to the position information of the target user relative to the air conditioner. The air conditioner stores preset actions and preset voice, the preset actions can be gestures, foot actions and the like, the preset voice can be preset music or recorded voice, the user can detect the actions or the output voice by the air conditioner, if the actions are the preset voice or the voice is the preset voice, the user can be judged to send a voice command, and at the moment, the air conditioner can adjust the sensitivity of the voice recognition device according to the position information of the user relative to the air conditioner. Through the mode, the problem that when a plurality of indoor users exist, the air conditioner cannot accurately adjust the sensitivity of the voice acquisition device is solved.
In the technical scheme provided by this embodiment, when the air conditioner detects the target information, the air conditioner acquires the position information of the user corresponding to the target information relative to the air conditioner, so that the air conditioner can know the user who wants to output the voice instruction in advance, and the sensitivity of the voice acquisition device can be accurately adjusted.
