[0037] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0038] The following combination Figures 1-4 The present invention describes an air conditioner control method, an air conditioner control device, and an electronic device.

[0039] The air conditioner control method according to the embodiment of the present invention may be executed by a processor. In some embodiments, the execution entity may also be a server. The execution entity of the air conditioner control method according to the embodiment of the present invention is not limited herein. The air conditioner control method according to the embodiment of the present invention is described below using a processor as an example.

[0040] like Figure 1 As shown, the air conditioner control method according to the embodiment of the present invention mainly includes step 110 , step 120 and step 130 .

[0041] Step 110 , when the target sound information is identified, infrared detection is performed on each target object in the target area to obtain a detection result.

[0042] It should be noted that the target area may be the coverage area when the air conditioner is in a working state, or the target area may also be the area where the air conditioner is installed.

[0043] There may be multiple target objects in the target area. When adjusting the working mode of the air conditioner, the overall status of the multiple target objects needs to be considered.

[0044] It is understandable that the target sound information may be a specific sound segment, and may include text information or may not include text information.

[0045] The target sound information can be collected by a microphone. The microphone can be directly installed on the indoor unit or outdoor unit of the air conditioner. Of course, in some embodiments, the microphone can also be installed at a certain position within the target area. There is no limitation on the installation position of the microphone.

[0046] The microphone can continuously collect ambient sounds, and perform simple filtering and noise reduction on the collected sound signals to generate an audio data stream.

[0047] It should be noted that the microphone is communicatively connected to the processor, and the microphone can send the collected audio data stream to the processor, and the processor can identify and process the collected audio data stream.

[0048] For example, in a classroom scenario, the target sound information may be the bell information for classes, the target area may be the classroom where the air conditioner is installed, and the target objects may be the students and teachers in the classroom.

[0049] In this case, infrared detection can be performed on each teacher and student in the classroom when the get out of class bell is recognized.

[0050] In some embodiments, if the target sound information does not include text information, the target sound information can be a get out of class bell set to pure music. In the process of identifying the get out of class bell, the target sound information can be identified by matching the spectrogram.

[0051] For example, the collected audio data stream may be subjected to Fourier transform processing to obtain a target spectrogram corresponding to the audio data stream, and then the target spectrogram may be compared with spectrograms in a pre-set spectrogram library.

[0052] If it is determined that there is a spectrogram in the spectrogram library that matches the generated target spectrogram, it can be determined that the target sound information has been recognized. It should be noted that the spectrogram library includes spectrograms corresponding to the bell sounds stored in advance.

[0053] In other embodiments, if the target sound information is a get out of class bell, the target sound information can be a get out of class reminder voice with text information or a song ring with lyrics. In the process of recognizing the get out of class bell, the target sound information can be recognized by using a corpus recognition method.

[0054] For example, corpus information from the collected audio data stream can be extracted and identified. When the target corpus is identified in the corpus information, it can be determined that the target sound information has been identified. It should be noted that the target corpus is the corpus associated with the target sound information in the collected audio data stream, and the target corpus can be the text included in the get out of class bell.

[0055] In other embodiments, the target sound information may also include multiple voices. That is, when multiple people are detected speaking simultaneously, the target sound information may be determined to have been recognized. Of course, the target sound information may also be other information, and the form and content of the target sound information are not limited herein.

[0056] In a classroom scenario, when the get out of class bell is recognized, infrared detection is performed on the teachers and students in the classroom to obtain the detection results.

[0057] It should be noted that performing infrared detection on each target object in the target area to obtain the detection result specifically includes collecting a thermal image of the target area. After collecting the thermal image, the comprehensive status of all target objects in the target area can be obtained by analyzing the thermal image.

[0058] In some embodiments, an infrared sensor can be used to capture the thermal image of the target area. In other embodiments, an infrared camera can be used to capture the thermal image of the target area. Of course, in other embodiments, other devices can be used to capture the thermal image of the target area. There is no restriction on the type of thermal image capture device.

[0059] The following describes the air conditioner control method according to an embodiment of the present invention by taking an infrared camera as an example.

[0060] In some embodiments, the infrared camera can be installed in the indoor unit of the air conditioner. Of course, in other embodiments, the infrared camera can also be installed at other locations within the target area. There is no restriction on the installation location of the infrared camera.

[0061] It is understandable that the infrared camera can emit infrared rays to each target object in the target area. The infrared rays irradiated to each target object are diffusely reflected and then received by the infrared camera to form a thermal image.

[0062] It should be noted that the infrared camera is connected to the processor for communication, and the infrared camera can send the collected thermal images to the processor in real time for image processing, thereby determining the detection results.

[0063] In some embodiments, when processing thermal images, a multi-target detection algorithm may be used to detect target objects in the thermal images. The multi-target detection algorithm may include a Deformable Parts Model (DPM) target detection algorithm, Faster R-CNN (Fast Region Convolutional Neural Networks), a Single Shot Multi Box Detector (SSD), or a YOLO (You Only Look Once) algorithm, among others. The type of image processing algorithm used for thermal images is not limited.

[0064] In some embodiments, multiple thermal images can be collected within a target time period and image processing can be performed on each thermal image. Based on the image processing results, the number of all target objects in each thermal image and the location information of each target object can be obtained. The image processing results of the multiple thermal images can then be analyzed to obtain the infrared detection results.

[0065] It can be understood that the detection result includes the quantity change and position change information of the target objects in the target area within the target time period.

[0066] Step 120: Determine the comprehensive status of all target objects in the target area based on the detection results.

[0067] It is understood that the comprehensive status of all target objects is associated with the number and position of all target objects. The comprehensive status is used to reflect the overall status of all target objects in the target area.

[0068] For example, in a classroom scenario, the target area may be the classroom, and the target objects may be the teachers and students in the classroom.

[0069] During class, all students sit in their seats and keep their positions relatively unchanged, and students will not leave the classroom. That is, the detection result is that the number and positions of all students in the classroom will remain relatively unchanged.

[0070] During get out of class breaks, some students will leave their seats and the classroom, the number of all students in the classroom will change, and the positions of some students will also change. That is, the detection result is a state where the number of all students in the classroom and the positions of at least some students will change.

[0071] In this case, infrared detection can be performed on all teachers and students in the classroom to obtain detection results, and then the comprehensive status of all students in the classroom during class and after class can be determined as two completely different states.

[0072] For another example, in a conference scenario, the target area may be the conference venue, and each target object may be a participant.

[0073] During the speaker's speech, other participants in the venue will stay in their seats and keep their positions relatively unchanged, and the number of all participants in the venue will remain unchanged. That is, the detection result is that the number and positions of all participants in the venue will remain relatively unchanged.

[0074] During the meeting discussion, all participants in the venue will not leave the venue, but will adjust their seats for discussion and communication. That is, the detection result is a state in which the positions of at least some of the participants in the venue will change.

[0075] In this case, infrared detection can be performed on all participants in the venue to obtain detection results, and then the comprehensive states of all participants in the venue during the speaker's speech and during the conference discussion can be determined as two completely different states.

[0076] Step 130: Determine the operating mode of the air conditioner based on the comprehensive status.

[0077] In the target area, when the comprehensive states of all target objects are different, different operating modes of the air conditioner can be determined according to the different comprehensive states.

[0078] It is understandable that when the comprehensive states of all target objects are different, different air-conditioning working modes are applicable to the target area.

[0079] For example, during a class in a classroom or a speaker's presentation in a conference, a relatively quiet environment is required to ensure that students and participants can hear the teacher or speaker clearly. In this case, the air conditioner should be set to a quieter mode.

[0080] In other words, during breaks and meetings, you don't need to worry too much about air conditioning noise. In these situations, students and attendees are quite active, and classroom doors are easily opened, which can lead to insufficient air conditioning performance and the need to increase cooling or heating. In these cases, the air conditioner should be set to a more efficient mode.

[0081] It is understandable that the comprehensive status of each target object can be determined based on the infrared detection results, and the air conditioner can be adjusted according to the working mode corresponding to the different comprehensive statuses.

[0082] In some embodiments, the working modes of the air conditioner corresponding to different comprehensive states in different scenarios can be stored in the memory in the form of a mapping table, and the processor can directly call and read the information in the mapping table to determine the working mode of the air conditioner.

[0083] Of course, in some other scenarios, the correspondence between the comprehensive status of each target object and the air-conditioning working mode can be set according to actual conditions. There is no restriction on the specific working mode matched by different comprehensive statuses.

[0084] In this embodiment, when target sound information is recognized, infrared detection is performed on each target object in the target area, so that the comprehensive status of each target object can be determined more accurately.

[0085] For example, if the teacher is staying late or an exam is in progress, if the bell rings but all students remain seated, the air conditioning needs of all students in the classroom will remain unchanged. By performing infrared detection on each student, the status of each student can be more accurately determined, and the overall status of all students can be more accurately determined.

[0086] For example, during a meeting, if the speaker's target voice message, "Start discussion," is recognized, but all attendees remain seated, discussing with their neighbors, without relocating, and the demand for air conditioning remains unchanged, the system can more accurately determine the location of each attendee and their overall status.

[0087] According to the air conditioner control method of an embodiment of the present invention, by performing infrared detection on each target object when the target sound information is identified, a more accurate comprehensive status of all targets can be obtained, and then a more accurate air conditioning usage demand of all target objects can be determined, so that the appropriate air conditioning working mode can be automatically determined to improve the user experience.

[0088] In some embodiments, step 120 mainly includes step 1201 and step 1202 .

[0089] 1201 : Determine a change in the number of target objects in a target area within a target time period based on the detection result.

[0090] It is understandable that multiple thermal images may be collected within a target time period, and image processing may be performed on each thermal image.

[0091] The target time period can be set to suit specific scenarios. In a classroom setting, the target time period can be set to 1-3 minutes. For example, the target time period can be 2 minutes long. The target time period starts when the bell rings for class or the end of get out of class.

[0092] In this case, image recognition can be performed on the thermal images collected at the start and end of the target time period, respectively, to obtain infrared detection results, and to determine the first number and the second number of target objects at the two moments, respectively.

[0093] After obtaining the first number and the second number of target quantities at two moments, a quantity change can be calculated, and the quantity change can be used as the quantity change of target objects in the target area within the target time period.

[0094] 1202. When the quantity change is greater than a first preset value, determine that the comprehensive state is the first state.

[0095] It should be noted that the first preset value is a manually set value, which can be set according to different scenarios and stored in the memory.

[0096] In a classroom scenario, considering that teachers may have more freedom in their behavior and that individual students may encounter unexpected events, the first preset value may be set to 1.

[0097] In the first state, when the bell is recognized, a large number of students leave the classroom. In this case, it can be determined that the students are in the end-of-get out of class state.

[0098] In this embodiment, by determining the quantity changes of all target objects, the comprehensive status of all target objects can be determined more accurately, thereby facilitating the determination of the working mode of the air conditioner.

[0099] In other embodiments, in step 1201: after determining the change in the number of target objects in the target area within the target time period based on the detection results, the air conditioner control method of the embodiment of the present invention further includes: when the change in the number is less than or equal to the first preset value, determining that the comprehensive state is the second state.

[0100] In this embodiment, the number of all target objects in the target area does not substantially change, and it can be determined that all target objects are in the second state in this case.

[0101] In the classroom scenario, when the bell is recognized, the change in quantity is 0, which means that there are no students leaving the classroom. In this case, it can be determined that the students are in class.

[0102] In this embodiment, by determining the quantity change of multiple target objects, the comprehensive status of all target objects can be determined more accurately, thereby facilitating the determination of the working mode of the air conditioner.

[0103] Similarly, in this embodiment, by determining the quantity change of all target objects, the comprehensive status of all target objects can be determined more accurately, thereby facilitating the determination of the working mode of the air conditioner.

[0104] In some embodiments, in step 1201: after determining the change in the number of target objects in the target area within the target time period based on the detection results, the air conditioner control method of the embodiment of the present invention further includes: determining a third number when the change is less than or equal to a first preset value.

[0105] In some scenarios, such as in a classroom, students are doing recess activities in the classroom; in another example, in a meeting, participants are having discussions in the meeting room.

[0106] In the above scenario, students will not leave the classroom and participants will not leave the venue. However, the students and participants will be more active and the demand for air conditioning will also change. Therefore, it is necessary to accurately identify the comprehensive status of all target objects in similar scenarios.

[0107] In this embodiment, by further analyzing the displacement of each target object, a more accurate comprehensive status of all target objects can be obtained.

[0108] In some embodiments, when processing a thermal image, a detection algorithm can be used to identify the human body heat source of a target object, construct a coordinate system on the thermal image, and obtain the upper, lower, left, and right coordinates of the human body heat source. Based on the relative relationship between the upper, lower, left, and right coordinates of the human body heat source, the same target object can be identified at different locations.

[0109] When calculating the displacement of the target object, the average position coordinates of the target object can be determined based on the average values of the upper coordinates, lower coordinates, left coordinates and right coordinates of the human body heat source, and then the displacement of the target object can be obtained by analyzing the change in the average position coordinates.

[0110] It can be understood that the second preset value is set in advance according to different scenarios, and the second preset value can be stored in the memory.

[0111] In this embodiment, the displacement of each target object is analyzed to obtain the number of target objects whose displacement within the target area is greater than the second preset value within the target time period, that is, the third number.

[0112] When the third number is greater than the second preset value, the comprehensive state is determined to be the first state. In a classroom scenario, the first preset value may be set to 2, considering that the teacher may have more freedom of behavior and that individual students may encounter unexpected events.

[0113] In this case, the number of target objects whose positions have changed is relatively large. In a classroom scenario, it can be determined that many students have changed positions, indicating that they are in the end of get out of class. In a meeting scenario, it can be determined that the participants are in a free discussion state.

[0114] In some embodiments, after determining the third number of target objects whose positions have changed within the target area within the target time period, the air conditioner control method of an embodiment of the present invention further includes: when the third number is less than or equal to a second preset value, determining that the state of the target area is the second state.

[0115] In this case, the number of target objects whose positions have changed is relatively small. In a classroom scenario, it can be determined that almost no students have changed positions, indicating that the students are in class. In a conference scenario, it can be determined that the participants are listening to a lecture.

[0116] According to the control method of the air conditioner according to the embodiment of the present invention, by further analyzing the displacement of each target object, the comprehensive status of all target objects can be obtained more accurately, and then the working mode of the air conditioner can be matched more accurately, thereby improving the user experience.

[0117] The control device of the air conditioner provided by the present invention is described below. The control device of the air conditioner described below and the control method of the air conditioner described above can be referred to each other.

[0118] The air conditioner control device according to the embodiment of the present invention includes a first processing module 310 , a second processing module 320 , and a third processing module 330 .

[0119] The first processing module 310 is used to perform infrared detection on each target object in the target area when the target sound information is recognized to obtain a detection result;

[0120] The second processing module 320 is used to determine the comprehensive status of all target objects in the target area based on the detection results;

[0121] The third processing module 330 is used to determine the operating mode of the air conditioner based on the comprehensive status.

[0122] According to the control device of the air conditioner according to an embodiment of the present invention, by performing infrared detection on each target object when the target sound information is identified, a more accurate comprehensive status of all targets can be obtained, and then a more accurate air conditioning usage demand of all target objects can be determined, so that the appropriate air conditioning working mode can be automatically determined to improve the user experience.

[0123] In some embodiments, the second processing module 320 is further used to determine the change in the number of target objects in the target area within the target time period based on the detection results; when the change in the number is greater than a first preset value, determine that the comprehensive state is the first state.

[0124] In some embodiments, the second processing module 320 is further configured to determine that the comprehensive state is the second state when the quantity change is less than or equal to the first preset value.

[0125] In some embodiments, the second processing module 320 is also used to determine a third number when the change amount is less than or equal to the first preset value, and the third number is the number of target objects with a displacement greater than the second preset value in the target area within the target time period; when the third number is greater than the second preset value, the comprehensive state is determined to be the first state.

[0126] In some embodiments, the second processing module 320 is further configured to determine that the comprehensive state is the second state when the third number is less than or equal to the second preset value.

[0127] An embodiment of the present invention also provides an air conditioner, which includes an indoor unit, an outdoor unit, and a processor and a memory arranged in the indoor unit or the outdoor unit; and also includes a program or instruction stored in the memory and runnable on the processor, and when the program or instruction is executed by the processor, the control method of the air conditioner as described above is executed.

[0128] The air conditioner provided according to an embodiment of the present invention can obtain a more accurate comprehensive status of all targets by performing infrared detection on each target object when the target sound information is identified, and then can determine a more accurate air conditioning usage demand of all target objects, thereby automatically determining the appropriate air conditioning working mode and improving the user experience.

[0129] In some embodiments, the working mode of the air conditioner includes at least a first working mode and a second working mode; the first working mode includes at least one of a left and right swing air on mode, an up and down sweep air on mode, and a mode in which the air conditioner compressor operates at a first frequency; the second working mode includes at least one of a left and right swing air off mode, an up and down sweep air off mode, and a mode in which the air conditioner compressor operates at a second frequency; the second frequency is less than the first frequency.

[0130] It is understandable that when the working state of the air conditioner includes the left and right swing air mode and the up and down sweep air mode, the air conditioner makes a louder noise, but it can accelerate the indoor air flow and the working effect of the air conditioner will be better.

[0131] In other words, when the working state of the air conditioner includes the left and right swing air closing mode and the up and down sweep air closing mode, the noise of the air conditioner is relatively small and the air conditioner also has a corresponding working effect.

[0132] In some embodiments, the working mode of the air conditioner is determined in the following manner: when the comprehensive state of all target objects in the target area is the first state, the working mode of the air conditioner is determined to be the first working mode; when the comprehensive state is the second state, the working mode of the air conditioner is determined to be the second working mode.

[0133] In some embodiments, the air conditioner is set to have a normal operating frequency of T, with a frequency unit of Hertz (HZ), and a normal outdoor unit fan blade speed of S, with a speed unit of revolutions per minute. The following describes the air conditioner of the present invention in detail using a classroom scenario as an example.

[0134] In the cooling state, when it is determined that the get out of class is over, that is, the student's comprehensive state is the first state, the compressor is turned on to increase the frequency. The frequency after the increase is T+6HZ, and the increase speed is 1HZ / 10 seconds. The increase will be completed after 1 minute, and then the fan blades are turned on to increase the speed. The speed is S+200 rpm, and the left and right swing winds are turned on at the same time, and the up and down swing winds are adjusted to fixed upward blowing.

[0135] When it is determined that the student is in the class state, that is, the comprehensive state of the student is the second state, the compressor is turned on to reduce the frequency. The frequency after reduction is T HZ, and the frequency reduction speed is 1HZ / 10 seconds. The frequency reduction is completed after 1 minute. At the same time, the fan blades return to the speed of S revolutions / minute, and the left and right swing and up and down swing are turned off.

[0136] In the heating state, when it is determined that the get out of class is over, that is, the student's comprehensive state is the first state, the compressor is turned on to increase the frequency. The frequency after the increase is T+6HZ, and the increase speed is 1HZ / 10 seconds. The increase will be completed after 1 minute, and then the fan blades are turned on to increase the speed. The speed is S+100 rpm, and the left and right swing winds are turned on at the same time, and the up and down swing winds are adjusted to fixed downward blowing.

[0137] When it is determined that the student is in the class state, that is, the comprehensive state of the student is the second state, the fan blades are first restored to a speed of S rpm, the left and right swing and up and down swing functions are turned off, and the compressor is turned on for frequency reduction.
