[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0028] In the related technology, the scheme of controlling the air conditioner through voice purely uses voice recognition technology to detect the sound signal. In this technical solution, in a noisy environment, the sound signal in the space is random, and a certain sound segment will appear. If it happens to match the command word for controlling the air conditioner, the air conditioner system misjudges that the user issued a voice control command, thus causing the air conditioner to malfunction.
[0029] In order to solve the above problems, the present invention proposes an air conditioner control method and system. The method and system for controlling an air conditioner according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
[0030] figure 1 is a flowchart of an air conditioner control method according to an embodiment of the present invention. like figure 1 As shown, the control method of the air conditioner in the embodiment of the present invention includes the following steps:
[0031] S1. Detect whether there is a user in the room where the air conditioner is located.
[0032] In one embodiment of the present invention, a camera is used to detect whether there is a user in the room where the air conditioner is located.
[0033] Specifically, the camera may monitor the room where the air conditioner is located to determine whether there is a user in the room.
[0034] S2, if there is a user, start the voice recognition function of the air conditioner.
[0035] Specifically, if it is detected that there is a user in the room where the air conditioner is located, the voice recognition function of the air conditioner is activated to reduce the impact on the voice recognition function when there is no one in the room but the surrounding environment is noisy, thereby preventing no one in the room The air conditioner malfunctions when there is a person.
[0036] In one embodiment of the present invention, after the user exists, it further includes: further obtaining the user's status, and judging whether the user's status meets the preset requirements, and if the preset requirements are met, then activating the voice recognition function of the air conditioner.
[0037] In one embodiment of the present invention, the state of the user is the user's face image information and the user's face orientation information.
[0038] In one embodiment of the present invention, judging whether the user's state meets the preset requirements specifically includes: identifying the user's face image information; if the user is a legal user, further judging whether the user's face orientation information is facing the air conditioner device; if yes, it is determined that the preset requirements are met.
[0039] Specifically, after it is judged that there is a user in the room where the air conditioner is located, the user information can be further judged, for example, the face image information of the user in the room is obtained through a camera, and the face image information is recognized to judge Whether it is a legitimate user, so as to ensure the security of air conditioning control. If it is a legitimate user, it is further judged whether the user's face is facing the air conditioner, if so, it is judged that the preset requirement is met, and then the voice recognition function of the air conditioner is started. For example, when the user is chatting in the room, and the user's face is not facing the air conditioner, then the voice recognition function of the air conditioner is not activated, which can avoid the user's chat content containing corresponding control instructions for the air conditioner. wrong control.
[0040] Further, after the voice recognition function of the air conditioner is activated, the user can be reminded that the voice recognition function has been activated through an indicator light or sound on the panel of the air conditioner, so as to inform the user that the air conditioner can be controlled by voice.
[0041] In one embodiment of the present invention, the user's state is the user's gesture information, and judging whether the user's state meets the preset requirements specifically includes: judging whether the user's gesture information is a preset gesture; if so, judging that the preset requirements are met .
[0042]It should be noted that when judging whether the user's state meets the preset requirements, there are three judging conditions above, namely: 1) whether the user's face image information is legal, 2) whether the user's face orientation information is facing the air conditioner device and 3) whether the user's gesture information is a preset gesture. When concretely implementing the control method of the air conditioner proposed by the present invention, these three conditions can be used alone, for example, when only judging that the user is a legitimate user, it can be judged that the user's state meets the preset requirements; it is also possible to combine the three conditions Combined use, for example, when 1) and 2) are met at the same time, or 1) and 3) are met at the same time, or 2) and 3) are met at the same time, it is judged that the user's status meets the preset requirements, of course, 1) can also be met at the same time , 2) and 3), it is determined that the user's status meets the preset requirements. How to use it depends on the specific situation.
[0043] S3, receiving voice information of the user, and generating a control instruction according to the voice information.
[0044] Specifically, after the voice recognition function of the air conditioner is activated, it receives voice information of the user and recognizes the voice information of the user to generate a control instruction.
[0045] S4, controlling the air conditioner according to the control instruction.
[0046] Specifically, the air conditioner is controlled according to the control instruction to complete the functions required by the user.
[0047] In one embodiment of the present invention, it also includes: turning off the voice recognition function of the air conditioner according to any one of the user's voice command, timing time and counting times.
[0048] Specifically, the user can actively close the current round of voice interaction through command words (that is, voice commands), for example, the command word "exit voice recognition" can be used to turn off the voice recognition function. Timeout and counting methods can also be used. For example, the timeout method is to set a time parameter t, and exit the current round of interaction when no valid voice is received within t seconds. The counting method is to set a count n, and exit the current round of interaction after n results are recognized. After exiting the current round of interaction, return to step S1.
[0049] In another embodiment of the present invention, in step S1, an infrared sensor may also be used to detect whether there is a user in the room where the air conditioner is located.
[0050] The control method of the air conditioner in the embodiment of the present invention first detects whether there is a user in the room where the air conditioner is located. If there is a user, the voice recognition function of the air conditioner is turned on. Human-hour air conditioner malfunctions, which improves user experience.
[0051] In order to realize the above embodiments, the present invention also proposes a control system for an air conditioner.
[0052] figure 2 is a block diagram of a control system of an air conditioner according to an embodiment of the present invention. like figure 2 As shown, the air conditioner control system according to the embodiment of the present invention includes: a user detection device 10 , a voice recognition device 20 and a control device 30 .
[0053] The user detection device 10 is used to detect whether there is a user in the room where the air conditioner is located.
[0054] In one embodiment of the present invention, the user detection device 10 includes a camera, and the user detection device 10 detects whether there is a user in the room where the air conditioner is located through the camera.
[0055] The voice recognition device 20 is used for receiving voice information of the user, and generating control instructions according to the voice information.
[0056] Specifically, the speech recognition device 20 recognizes the user's speech information to generate a control command, and outputs the control command to the control device 30 .
[0057] The control device 30 is connected to the user detection device 10 and the voice recognition device 20 respectively. The control device 30 is used to control and activate the voice recognition device 20 when there is a user in the room where the air conditioner is located, and to control the air conditioner according to the control instructions.
[0058] Specifically, when the user detection device 10 detects that there is a user in the room where the air conditioner is located, the control device 30 controls and activates the voice recognition device 20, so as to reduce the impact on the voice recognition function when there is no one in the room but the surrounding environment is noisy. influence, thereby preventing the air conditioner from malfunctioning when there is no one in the room.
[0059] In an embodiment of the present invention, the user detection device 10 is also used to further obtain the user's status after detecting the presence of the user, and judge whether the user's status meets the preset requirements; the control device 30 is specifically used to meet the preset requirements. The speech recognition device 20 is activated when required.
[0060] In an embodiment of the present invention, the state of the user is the user's face image information and the user's face orientation information.
[0061] In one embodiment of the present invention, the user detection device 10 judges whether the user's state meets the preset requirements specifically: identifying the user's face image information, and if the user is a legal user, further judging whether the user's face orientation information is is facing the air conditioner, if yes, it is determined that the preset requirements are met.
[0062] Specifically, after the user detection device 10 detects that there is a user in the room where the air conditioner is located, the user's information can be further detected through the camera. For example, the face image information of the user in the room is obtained through the camera, and the face image information is recognized to determine whether the user is a legitimate user, thereby ensuring the safety of the air conditioner control. If it is a legitimate user, it is further judged whether the user's face is facing the air conditioner, and if so, the user detection device 10 judges that the preset requirements are met, and the control device 30 then controls and starts the voice recognition device 20 . For example, when the user is chatting in the room, and the user's face is not facing the air conditioner, then the voice recognition device 20 is not activated, which can avoid miscontrolling the air conditioner when the user's chat content contains a corresponding control instruction for the air conditioner. .
[0063] In one embodiment of the present invention, the state of the user is the user's gesture information, and the user detection device 10 judges whether the user's state meets the preset requirements, specifically: judging whether the user's gesture information is a preset gesture, if so, then Meet preset requirements.
[0064] It should be noted that when the user detection device 10 judges whether the user's state meets the preset requirements, there are three judgment conditions mentioned above, namely: 1) whether the user's face image information is legal, and 2) whether the user's face orientation information is legal. is facing the air conditioner and 3) whether the gesture information of the user is a preset gesture. In specific implementation, these three conditions can be used alone, for example, it can be judged that the user's status meets the preset requirements when only judging that the user is a legitimate user; the three conditions can also be used in combination, for example, satisfying 1) at the same time and 2), or both 1) and 3) or both 2) and 3), it is judged that the user's status meets the preset requirements, of course, it can also be judged when 1), 2) and 3) are satisfied at the same time The user's status meets the preset requirements. How to use it depends on the specific situation.
[0065] Further, after the control device 30 controls the voice recognition device 20 to start, it can control the indicator light on the panel of the air conditioner or sound to prompt the user that the voice recognition function is turned on, so as to inform the user that the air conditioner can be controlled by voice.
[0066] In an embodiment of the present invention, the control device 30 is also used for: shutting down the speech recognition device 20 according to any one of the user's voice instruction, timing time and counting times.
[0067] Specifically, the user can actively close the current round of voice interaction through command words (ie, voice instructions), for example, the user can use the command word "exit voice recognition" to turn off the voice recognition function. The control device 30 can also use timeout and counting methods. For example, the timeout method is to set a time parameter t, and exit the current round of interaction when no valid voice is received within t seconds, that is, control the voice recognition device 20 to turn off. The counting method is to set a count n, and exit the current round of interaction after n results are recognized.
[0068] In another embodiment of the present invention, the user detection device 10 includes an infrared sensor, and the user detection device 10 detects whether there is a user in the room where the air conditioner is located through the infrared sensor.
[0069] In the control system of the air conditioner in the embodiment of the present invention, the user detection device detects whether there is a user in the room where the air conditioner is located. If there is a user, the control device controls to start the voice recognition device. If there is no user, it does not open, thereby preventing the room The air conditioner malfunctions when there is no one in the room, which improves the user experience.
