[0002] Currently, with the rapid development of air conditioning technology, more and more air conditioners are being equipped with fresh air modules. For example, multi-split air conditioners installed in commercial spaces or other high-density areas need to be equipped with fresh air modules to introduce outdoor fresh air and adjust indoor air quality requirements. However, existing multi-split air conditioners in high-density areas cannot effectively adjust the fresh air volume in each air conditioning operating area, resulting in high fresh air load and energy consumption, as well as energy waste. This leads to poor energy-saving performance of the air conditioners and fails to meet the current energy-saving operation requirements of air conditioners. Summary of the Invention

[0003] This application provides an air conditioning control method, device, air conditioner, and storage medium, aiming to solve the technical problems of high fresh air load and energy consumption and poor energy-saving effect in existing multi-split fresh air air conditioners.

[0004] On one hand, embodiments of this application provide an air conditioning control method, which includes the following steps:

[0006] Image recognition is performed on the regional image stream to determine personnel information in each air-conditioning operating area of ​​the regional image stream;

[0007] Based on the personnel information, the target fresh air volume for each air-conditioned operating area is determined, and the target air conditioning unit is driven to adjust the air quality of the air-conditioned operating area according to the target fresh air volume.

[0009] Obtain the initial background image stream associated with the region image stream;

[0010] The background image stream is updated based on the region image stream to obtain an updated background image stream;

[0011] Based on the updated background image stream, image recognition is performed on the regional image stream to determine the personnel information of each air-conditioning operating area in the regional image stream.

[0012] In one possible implementation of this application, the step of updating the background image stream based on the region image stream to obtain an updated background image stream includes:

[0013] Acquire a first initial image and a second initial image from the region image stream, wherein the first initial image is background image information from the region image stream data acquired at the previous moment, and the second initial image is background image information from the region image stream data acquired at the current moment;

[0014] The first initial image is segmented to obtain a first background image, and the second initial image is segmented to obtain a second background image;

[0015] If the similarity between the first background image and the second background image is less than a preset similarity threshold, then the initial background image stream is updated based on the second initial image to obtain an updated background image stream.

[0016] In one possible implementation of this application, the step of performing image recognition on the regional image stream based on the updated background image stream to determine personnel information for each air-conditioning operating area in the regional image stream includes:

[0018] Image detection is performed on the target image features to obtain each candidate detection object in the target image features;

[0019] If the predicted human face probability of any of the candidate detection objects is greater than or equal to a preset probability threshold, then the candidate object is determined as the target human object.

[0020] The target personnel are located and identified to obtain personnel information for each air conditioning operating area. The personnel information includes the activity status information and location information of the target personnel.

[0021] In one possible implementation of this application, the step of locating and identifying the target personnel to obtain personnel information for each of the air conditioning operating areas includes:

[0022] The target person is located and identified to obtain the initial location information of the target person.

[0023] Calculate the location dwell time of the initial location information. If the location dwell time is greater than a preset time threshold, then set the initial location information as the object location information of the target person object.

[0024] By summarizing the activity status information and location information of each target person, the personnel information of each air-conditioning operating area is obtained.

[0029] If the number of target personnel in the air-conditioning operation area is greater than the first number threshold, the opening of the fresh air valve of the target air-conditioning unit corresponding to the air-conditioning operation area is increased according to the activity status information of each target personnel to obtain the target fresh air volume of the air-conditioning operation area.

[0030] If the number of target personnel in the air-conditioning operation area is less than the first number threshold, the opening of the fresh air valve of the target air-conditioning unit in the air-conditioning operation area is reduced according to the activity status information of each target personnel to obtain the target fresh air volume of the air-conditioning operation area.

[0032] If the number of target personnel in the personnel information corresponding to the air conditioning operating area is equal to the second number threshold, then the air conditioning operating area is determined as an unmanned operating area.

[0033] Close the fresh air valve in the unmanned operating area and drive the target air conditioning unit corresponding to the unmanned operating area to draw in the target fresh air for treatment in the unmanned operating area;

[0034] The target air conditioning unit is driven to use the target treated fresh air to regulate the air quality of other air-conditioned operating areas.

Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0055] Currently, with the rapid development of air conditioning technology, more and more air conditioners are being equipped with fresh air modules. For example, multi-split air conditioners installed in commercial spaces or other high-density areas need to be equipped with fresh air modules to introduce outdoor fresh air and adjust indoor air quality requirements. However, existing multi-split air conditioners in high-density areas cannot effectively adjust the fresh air volume in each air conditioning operating area, resulting in high fresh air load and energy consumption, as well as energy waste. This leads to poor energy-saving performance of the air conditioners and fails to meet the current energy-saving operation requirements of air conditioners.

[0056] Based on this, this application proposes an air conditioning control method, device, equipment, and computer-readable storage medium to solve the technical problems of high fresh air load and energy consumption and poor energy-saving effect in existing multi-split fresh air air conditioners.

[0057] The air conditioning control method in this embodiment of the invention is applied to an air conditioning control device, which is installed in an air conditioner. The air conditioner is provided with one or more processors, a memory, and one or more application programs. The one or more application programs are stored in the memory and configured to be executed by the processor to implement the air conditioning control method. The air conditioner can be a multi-split intelligent air conditioner, such as a portable air conditioner, a window air conditioner, a wall-mounted air conditioner, a floor-standing air conditioner, and a central air conditioner, etc.

[0058] like Figure 1 As shown, Figure 1 This is a schematic diagram of a scenario for an air conditioning control method according to an embodiment of the present application. The air conditioning control scenario in this embodiment includes an air conditioner 100 (the air conditioner 100 integrates an air conditioning control device), and the air conditioner 100 has a computer-readable storage medium corresponding to the air conditioning control method running in it to execute the steps of the air conditioning control method.

[0059] Understandable, Figure 1The air conditioner in the air conditioning control method scenario shown, or the device contained in the air conditioner, does not constitute a limitation on the embodiments of the present invention. That is, the number or type of air conditioner in the air conditioning control method scenario, or the number or type of device contained in each device, does not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0060] In this embodiment of the invention, the air conditioner 100 is mainly used to: respond to a multi-split air conditioner control request and collect a regional image stream of the air conditioner operating area corresponding to the target air conditioner unit;

[0061] Image recognition is performed on the regional image stream to determine personnel information in each air-conditioning operating area of ​​the regional image stream;

[0062] Based on the personnel information, the target fresh air volume for each air-conditioned operating area is determined, and the target air conditioning unit is driven to adjust the air quality of the air-conditioned operating area according to the target fresh air volume.

[0063] The air conditioner 100 in this embodiment of the invention can be a multi-split air conditioner with fresh air conditioning function, comprising at least one portable air conditioner, window air conditioner, wall-mounted air conditioner, and floor-standing air conditioner. Furthermore, the air conditioner can also be a central air conditioning system.

[0064] This application provides an air conditioning control method, apparatus, device, and computer-readable storage medium, which will be described in detail below.

[0065] It will be understood by those skilled in the art that Figure 1 The application environment shown is only one application scenario related to the solution of this application and does not constitute a limitation on the application scenario of this application. Other application environments may include more than one application scenario. Figure 1 The number of more or fewer air conditioners shown, or the air conditioning control network connections, for example Figure 1 Only one air conditioner is shown in the image. It is understood that the scenario of the air conditioning control method may also include one or more air conditioners, which is not limited here. The air conditioner 100 may also include a memory for storing image stream data and other data.

[0066] It should be noted that, Figure 1 The schematic diagram of the air conditioning control method shown is merely an example. The scenarios of the air conditioning control method described in the embodiments of the present invention are intended to more clearly illustrate the technical solutions of the embodiments of the present invention and do not constitute a limitation on the technical solutions provided in the embodiments of the present invention.

[0067] Based on the scenarios described above for air conditioning control methods, various embodiments of the air conditioning control method disclosed in this invention are proposed.

[0068] like Figure 2 As shown, Figure 2 This is a flowchart illustrating one embodiment of the air conditioning control method in this application. The air conditioning control method includes the following steps 201 to 203:

[0069] 201. Respond to the control request of the multi-split air conditioner and collect the regional image stream of the air conditioner operating area corresponding to the target air conditioner unit;

[0070] The air conditioning control method in this embodiment is applied to an air conditioner. The type and number of air conditioners are not specifically limited. That is, the air conditioner can be a multi-split fresh air air conditioner composed of multiple target air conditioning units with fresh air conditioning function (wherein, the target air conditioning unit can be any one or more of portable air conditioners, window air conditioners, wall-mounted air conditioners, cabinet air conditioners, and central air conditioners, etc.). In a specific embodiment, the air conditioner is a multi-split fresh air air conditioner.

[0071] Specifically, the air conditioner in this embodiment can install one or more indoor units in different building indoor areas, thereby achieving multi-split air conditioning to adjust different building indoor areas. These building indoor areas can be any building indoor area, such as residences, shopping malls, office buildings, and factories. For example, in one specific embodiment, the air conditioner can be installed in high-density buildings such as shopping malls. Each target air conditioning unit in the air conditioner corresponds to a specific area within the mall. Because shopping malls have high and fluctuating foot traffic, the air conditioner also needs to dynamically adjust the fresh air volume based on the personnel information in the air conditioning operation area corresponding to each target air conditioning unit, thereby reducing the fresh air load of the air conditioner and improving its fresh air utilization rate and energy-saving effect.

[0072] Specifically, during operation, the air conditioner responds to multi-split air conditioning control requests. These requests are operational instructions that drive the air conditioner to dynamically control fresh air based on the personnel information corresponding to each target air conditioning unit. Optionally, the triggering method for these control requests is not specifically limited here; that is, the request can be actively triggered by the user, for example, by clicking the fresh air control button on a remote control device connected to the air conditioner. Alternatively, the request can be automatically triggered by the air conditioner, for example, by a pre-set fresh air control process that automatically triggers the control requests within a preset time period.

[0073] Specifically, after receiving the control request from the multi-split air conditioning system, the air conditioner determines the corresponding operating area of ​​each target air conditioning unit and acquires a regional image stream of that operating area. This operating area is the indoor area where the target air conditioning unit performs air conditioning. Each target air conditioning unit corresponds to one operating area. The regional image stream is a video stream of the operating area captured by photographing the air conditioning unit while it is in operation.

[0074] Specifically, during operation, the air conditioner also uses target cameras to capture video images of the corresponding air-conditioning operating area of ​​each target air-conditioning unit, and sets this video image as a regional image stream for that air-conditioning operating area. This regional image stream can reflect information about human activity in that air-conditioning operating area (such as pedestrian traffic and activity status).

[0075] Optionally, the target camera can be a camera installed on the target air conditioning unit, or it can be a monitoring camera that communicates with the target air conditioning unit via an IoT communication link in the air conditioning operating area, using that monitoring camera as the target camera. The target camera can be any one or more of an infrared camera, a binocular camera, a depth camera, and a thermal imaging camera.

[0076] 202. Perform image recognition on the regional image stream to determine the personnel information of each air-conditioning operating area in the regional image stream;

[0077] Specifically, after acquiring the regional image stream of the air-conditioning operating area corresponding to each target air-conditioning unit, the air conditioner performs image recognition on the regional image stream to determine the personnel information of each air-conditioning operating area in the regional image stream. This personnel information consists of parameters characterizing the flow of people and their activity status within the air-conditioning operating area. This personnel information may include the activity status information and location information of the target personnel. The activity status information characterizes the current activity status of the target personnel; for example, it can be information about movement or stillness.

[0078] Specifically, after acquiring the regional image streams of each air-conditioning operating area, in order to improve the accuracy of image recognition and avoid result errors caused by scene changes, the air conditioner also generates an initial background image stream associated with the regional image stream from multiple images in the regional image stream.

[0079] Specifically, after acquiring the initial background image stream, the air conditioner updates the background image stream based on the regional image stream to obtain an updated background image stream. That is, the air conditioner acquires a first initial image and a second initial image from the regional image stream and updates the background of that regional image stream to obtain the regional image stream. Here, the first initial image is the scene image information from the regional image stream data acquired at the previous moment, and the second initial image is the scene image information from the regional image stream data acquired at the current moment. In other words, the scene background information represented by the first initial image is earlier than the background information represented by the second initial image.

[0080] Specifically, after acquiring the regional image streams of each air-conditioning operating area, the air conditioner performs background segmentation processing on these regional image streams to obtain a first background image and a second background image in the initial video stream. The first background image is a background image stream representing the historical background information of the initial video stream. The second background image is a background image stream representing the current background information of the initial video stream.

[0081] Specifically, after acquiring the first background image, the air conditioner initializes the first background image to obtain an initialized first background image. It then compares the first background image with the current second background image in the region image stream to obtain a comparison result. Based on the comparison result, it adjusts the region image stream to obtain the region image stream, thereby reducing the result error caused by scene changes.

[0082] Optionally, if the comparison result shows that the similarity between the first background image and the second background image is greater than or equal to a preset similarity threshold, then it is determined that the scene of the initial video stream has not changed, and there is no need to adjust the background image stream corresponding to the initial video stream.

[0083] Optionally, if the comparison result shows that the similarity between the first background image and the second background image is less than a preset similarity threshold, it is determined that the scene of the initial video stream has changed. In order to reduce the result error caused by the scene change, the air conditioner uses the second initial image to update the background of the initial background image stream to obtain an updated background image stream.

[0084] Specifically, after acquiring the updated background image stream, the air conditioner also uses the updated background image stream to perform image recognition on the image stream of that area, thereby determining the personnel information of each air-conditioning operating area in the image stream of that area.

[0085] Specifically, the air conditioner uses the updated background image stream to segment the image stream of the region, obtains the foreground image stream in the image stream of the region, and inputs the foreground image stream into a pre-set image recognition model for image recognition, thereby determining the object location information and activity status information of each target person in each air-conditioning operation area in the initial image stream, so as to determine the flow of people and the status of people in different air-conditioning operation areas, and then adjust the target fresh air volume of the air-conditioning operation area according to the flow of people and the status of people.

[0086] 203. Determine the target fresh air volume for each air-conditioned operating area based on the personnel information, and drive the target air conditioning unit to adjust the air quality of the air-conditioned operating area according to the target fresh air volume.

[0087] Specifically, after determining the personnel information of each air-conditioned operating area, the air conditioner also determines the target fresh air volume for each air-conditioned operating area based on the personnel information, and drives the target air conditioning unit to adjust the air quality of the air-conditioned operating area according to the target fresh air volume. That is, the air conditioner drives the target air conditioning unit to transmit fresh air to the air-conditioned operating area according to the target fresh air volume in order to adjust the air in the air-conditioned operating area and improve the regional comfort of the air-conditioned operating area.

[0088] Specifically, after the air conditioner obtains the personnel information of each air-conditioned operating area, it determines the number of target personnel in each air-conditioned operating area and the activity status information of each target personnel in the air-conditioned operating area based on the personnel information, and determines the target fresh air volume of the air-conditioned operating area based on the number of target personnel and activity status information.

[0089] Optionally, the air conditioner is pre-set with a first number threshold to detect the flow of people in the air-conditioned operating area, and the first number threshold is compared with the target number of people to determine the target fresh air volume for the air-conditioned operating area based on the comparison result. The first number threshold is the number threshold determined by the minimum fresh air volume required to meet the hygiene requirements of a commercial building.

[0090] Optionally, if the target number of people in the air-conditioned operating area is greater than a first number threshold, the air conditioner determines that the fresh air volume in the air-conditioned operating area needs to be increased, and increases the opening of the fresh air valve of the corresponding target air conditioning unit in the air-conditioned operating area according to the activity status information of each target person, to obtain the target fresh air volume for the air-conditioned operating area. That is, after determining that the target number of people in the air-conditioned operating area is greater than the first number threshold, the air conditioner further calculates the difference between the target number of people and the first number threshold, and corrects the difference according to the activity status information of each target person. If the activity status information is "away from activity", the air conditioner subtracts the number of people whose activity status information is "away from activity" from the difference to obtain the target number difference, and queries the preset control database to determine the fresh air volume corresponding to the target number difference. This fresh air volume is determined as the target fresh air volume for the air-conditioned operating area, and outdoor fresh air is introduced to adjust the air quality of the air-conditioned operating area according to this target fresh air volume.

[0091] Optionally, if the target number of people in the air-conditioned operating area is less than a first number threshold, the opening of the fresh air valve of the corresponding target air conditioning unit in the air-conditioned operating area is reduced according to the activity status information of each target person, to obtain the target fresh air volume for the air-conditioned operating area. That is, after determining that the target number of people in the air-conditioned operating area is less than the first number threshold, the air conditioner further calculates the difference between the target number of people and the first number threshold, and corrects the difference based on the activity status information of each target person. If the activity status information is "away from activity", the air conditioner subtracts the number of people whose activity status information is "away from activity" from the difference to obtain the target number difference, and queries the preset control database to determine the fresh air volume corresponding to the target number difference. This fresh air volume is then determined as the target fresh air volume for the air-conditioned operating area, and the air quality in the air-conditioned operating area is adjusted by reducing the introduction of outdoor fresh air according to this target fresh air volume.

[0092] Optionally, in other embodiments, the air conditioner can also directly determine the corresponding target fresh air volume based on the target number of people in the air-conditioned operating area, thereby reducing the calculation burden on the air conditioner.

[0093] Optionally, in other embodiments, when the number of target personnel in the air-conditioned operating area reaches the second number threshold, the air conditioner also performs an air back-suction operation on the air-conditioned operating area, thereby introducing the treated fresh air and cooled or heated air into other air-conditioned operating areas, thereby reducing the energy consumption and fresh air waste of the air conditioner.

[0094] In this embodiment, the air conditioner, in response to a multi-split air conditioner control request, acquires a regional image stream of the operating area corresponding to the target air conditioning unit; performs image recognition on the regional image stream to determine the personnel information of each air conditioning operating area in the regional image stream; determines the target fresh air volume for each air conditioning operating area based on the personnel information, and drives the target air conditioning unit to adjust the air quality of the air conditioning operating area according to the target fresh air volume. This achieves improved energy utilization of the air conditioner by dynamically adjusting the target fresh air volume of each air conditioning operating area based on the activity status of personnel in the corresponding air conditioning operating area, driving the target air conditioning unit to adjust the air quality of each air conditioning operating area according to the target fresh air volume, thereby reducing energy waste caused by the multi-split air conditioner when the fresh air mode is activated, and ultimately achieving better air conditioning energy-saving effects.

[0095] like Figure 3 As shown, Figure 3 This is a flowchart illustrating an embodiment of the air conditioning control method for determining personnel information in each air conditioning operating area provided in this application. Specifically, in this embodiment, the air conditioning control method further includes steps 301 to 304:

[0096] 301. Using a preset target extraction model, perform portrait feature extraction based on the updated background image stream and the region image stream to obtain target image features;

[0097] 302. Perform image detection on the target image features to obtain each candidate detection object in the target image features;

[0098] 303. If the predicted human image probability of any of the candidate detection objects is greater than or equal to a preset probability threshold, then the candidate object is determined as the target human object;

[0099] 304. Locate and identify the target personnel to obtain personnel information for each air conditioning operating area. The personnel information includes the activity status information and location information of the target personnel.

[0100] Based on the above embodiments, in this embodiment, after the air conditioner obtains the updated background image stream, it also uses the updated background image stream to perform image recognition on the regional image stream, thereby determining the personnel information of each air-conditioning operating area in the regional image stream.

[0101] Specifically, the air conditioner is pre-set with a target extraction model for feature extraction of the updated background image stream and the region image stream. The air conditioner inputs the updated background image stream and the region image stream into the target extraction model, and uses the target extraction model to extract human features based on the updated background image stream and the region image stream to obtain target image features. That is, after obtaining the updated background image stream, the target extraction model extracts the updated background features in the updated background image stream, and performs background segmentation on the region image stream based on the updated background features to obtain the foreground image stream of the region image stream. The target extraction model further extracts human features from the foreground image stream to obtain target image features, wherein the target image features are image feature information representing each object in the region image stream.

[0102] Specifically, after acquiring the target image features, the air conditioner performs image detection on the target image features to determine each candidate detection object in the target image features. The candidate detection objects are each candidate object that may be the target person or other object.

[0103] Optionally, if the predicted human image probability of any candidate detection object is greater than or equal to a preset probability threshold, then the candidate detection object is determined as the target person object. The preset probability threshold is similarity threshold information characterizing whether the candidate detection object is human. After acquiring the target person object in the air conditioning operating area, the air conditioner further performs location identification on the target person object to obtain personnel information for each air conditioning operating area. The personnel information includes the target person object's activity status information and object location information.

[0104] Optionally, the air conditioner performs location identification on the target person to obtain the target person's initial location information. Further, to determine the accuracy of this initial location information, the air conditioner calculates the duration of the initial location dwell time and compares this dwell time with a preset duration threshold to determine the validity of the initial location information.

[0105] Optionally, if the duration of stay at the location exceeds a preset duration threshold, the air conditioner determines that the initial location information is valid location information and sets the initial location information as the object location information of the target person.

[0106] Specifically, after acquiring the location information of target personnel in each air-conditioned operating area, the air conditioner further identifies the activity status information of the target personnel. That is, the air conditioner determines the activity intention of the target personnel based on several frames of image information in the area image stream, identifies the activity intention as the activity status information of the target personnel, and summarizes the activity status information and location information of each target personnel to obtain the personnel information for each air-conditioned operating area. Among them, the activity status information includes stationary status information and movement status information.

[0107] Specifically, after determining the personnel information of each air-conditioned operating area, the air conditioner also determines the target fresh air volume for each air-conditioned operating area based on the personnel information, and drives the target air conditioning unit to adjust the air quality of the air-conditioned operating area according to the target fresh air volume. That is, the air conditioner drives the target air conditioning unit to transmit fresh air to the air-conditioned operating area according to the target fresh air volume in order to adjust the air in the air-conditioned operating area and improve the regional comfort of the air-conditioned operating area.

[0108] In this embodiment, the air conditioner extracts human features based on the updated background image stream and the region image stream using a preset target extraction model to obtain target image features; image detection is performed on the target image features to obtain candidate detection objects; if the human prediction probability of any candidate detection object is greater than or equal to a preset probability threshold, the candidate detection object is identified as the target person object; the target person object is located and identified to obtain personnel information for each air conditioner operating area, including the activity status information and location information of the target person object. This achieves accurate identification of personnel information in each air conditioner operating area of ​​a multi-split fresh air air conditioner, providing a data foundation for subsequent dynamic adjustment of the fresh air volume in each air conditioner operating area.

[0109] like Figure 4 As shown, Figure 4 This is a flowchart illustrating an embodiment of the air conditioning control method for determining a target fresh air volume provided in this application. Specifically, in this embodiment, the air conditioning control method further includes steps 401 to 403:

[0110] 401. If the number of target personnel in the personnel information corresponding to the air conditioning operating area is equal to the second number threshold, then the air conditioning operating area is determined as an unmanned operating area;

[0111] 402. Close the fresh air valve in the unmanned operating area, and drive the target air conditioning unit corresponding to the unmanned operating area to draw in the target fresh air from the unmanned operating area;

[0112] 403. Drive the target air conditioning unit to use the target treated fresh air to adjust the air quality of other air-conditioned operating areas.

[0113] Based on the above embodiments, in this embodiment, when the number of target personnel in the air-conditioned operating area reaches the second number threshold, the air conditioner also performs an air back-suction operation on the air-conditioned operating area, thereby introducing treated fresh air and cooled or heated air into other air-conditioned operating areas, thus reducing the energy consumption and fresh air waste of the air conditioner. The second number threshold is 0.

[0114] Specifically, during operation, the air conditioner monitors the number of target personnel in the personnel information of each air-conditioned operating area in real time. When the number of target personnel in the personnel information corresponding to the air-conditioned operating area is equal to the second number threshold, the air conditioner determines that there are no personnel in the air-conditioned operating area and identifies the air-conditioned operating area as an unmanned operating area.

[0115] Optionally, in other embodiments, in order to improve control accuracy, the air conditioner further calculates the duration for which the number of target personnel equals a second personnel threshold. Only when the duration exceeds a preset duration threshold is the air conditioning operating area determined as an unmanned operating area, thereby avoiding misjudgment that could affect normal personnel activities.

[0116] Specifically, after determining that there is an unoccupied area, the air conditioner closes the fresh air valve in that area and shuts down the indoor cooling or heating functions. Since the air in the unoccupied area is already treated fresh air, to avoid wasting this treated fresh air, the air conditioner also drives the indoor fan of the corresponding target air conditioning unit in the unoccupied area to reverse. This allows the indoor fan to draw in the treated fresh air and deliver it into the target air duct. The target air conditioning unit then mixes this treated fresh air with the treated air in other air-conditioned areas, and uses the mixed air to regulate the air quality in the other air-conditioned areas. This reduces the fresh air energy consumption of other units and thus lowers overall air conditioning energy consumption.

[0117] In this embodiment, if the number of target personnel in the personnel information corresponding to the air-conditioned operating area is equal to a second personnel threshold, the air-conditioned operating area is determined to be an unoccupied operating area. The fresh air valve in the unoccupied operating area is closed, and the target air conditioning unit corresponding to the unoccupied operating area is driven to draw in the target treated fresh air from the unoccupied operating area. The target air conditioning unit is then driven to use the target treated fresh air to regulate the air quality of other air-conditioned operating areas. This achieves the transfer of the treated target fresh air from an unoccupied air-conditioned operating area to other occupied air-conditioned operating areas, thereby reducing the fresh air energy consumption of the air conditioner.

[0118] To better implement the air conditioning control method in the embodiments of this application, an air conditioning control device is also provided in the embodiments of this application, such as... Figure 5 As shown, Figure 5 This is a schematic diagram of the structure of the air conditioning control device provided in the embodiments of this application. Specifically, the air conditioning control device 500 includes:

[0119] The image acquisition module 501 is configured to respond to the control request of the multi-split air conditioner and acquire a regional image stream of the air conditioner operating area corresponding to the target air conditioner unit.

[0122] In one possible implementation of this embodiment, the air conditioning control device performs image recognition on the regional image stream to determine personnel information for each air-conditioned operating area in the regional image stream, including:

[0123] Obtain the initial background image stream associated with the region image stream;

[0124] The background image stream is updated based on the region image stream to obtain an updated background image stream;

[0125] Based on the updated background image stream, image recognition is performed on the regional image stream to determine the personnel information of each air-conditioning operating area in the regional image stream.

[0126] In one possible implementation of this embodiment, the air conditioning control device updates the background image stream based on the regional image stream to obtain an updated background image stream, including:

[0127] Acquire a first initial image and a second initial image from the region image stream, wherein the first initial image is background image information from the region image stream data acquired at the previous moment, and the second initial image is background image information from the region image stream data acquired at the current moment;

[0128] The first initial image is segmented to obtain a first background image, and the second initial image is segmented to obtain a second background image;

[0129] If the similarity between the first background image and the second background image is less than a preset similarity threshold, then the initial background image stream is updated based on the second initial image to obtain an updated background image stream.

[0130] In one possible implementation of this embodiment, the air conditioning control device performs image recognition on the regional image stream based on the updated background image stream to determine personnel information for each air conditioning operating area in the regional image stream, including:

[0132] Image detection is performed on the target image features to obtain each candidate detection object in the target image features;

[0133] If the predicted human face probability of any of the candidate detection objects is greater than or equal to a preset probability threshold, then the candidate object is determined as the target human object.

[0134] The target personnel are located and identified to obtain personnel information for each air conditioning operating area. The personnel information includes the activity status information and location information of the target personnel.

[0135] In one possible implementation of this embodiment, the air conditioning control device locates and identifies the target personnel to obtain personnel information for each of the air conditioning operating areas, including:

[0136] The target person is located and identified to obtain the initial location information of the target person.

[0137] Calculate the location dwell time of the initial location information. If the location dwell time is greater than a preset time threshold, then set the initial location information as the object location information of the target person object.

[0138] By summarizing the activity status information and location information of each target person, the personnel information of each air-conditioning operating area is obtained.

[0139] In one possible implementation of this embodiment, the air conditioning control device determines the target fresh air volume for each air-conditioned operating area based on the personnel information, including:

[0140] Based on the personnel information, determine the number of target personnel in each of the air conditioning operation areas and the activity status information of each target personnel;

[0141] The target fresh air volume for each air-conditioned operating area is determined based on the target number of personnel and the activity status information.

[0142] In one possible implementation of this embodiment, the air conditioning control device determines the target fresh air volume for each air conditioning operating area based on the target number of people and the object attribute information, including:

[0143] If the number of target personnel in the air-conditioning operation area is greater than the first number threshold, the opening of the fresh air valve of the target air-conditioning unit corresponding to the air-conditioning operation area is increased according to the activity status information of each target personnel to obtain the target fresh air volume of the air-conditioning operation area.

[0144] If the number of target personnel in the air-conditioning operation area is less than the first number threshold, the opening of the fresh air valve of the target air-conditioning unit in the air-conditioning operation area is reduced according to the activity status information of each target personnel to obtain the target fresh air volume of the air-conditioning operation area.

[0145] In one possible implementation of this embodiment, the air conditioning control device drives the target air conditioning unit to adjust the air quality of the air-conditioned operating area according to the target fresh air volume, including:

[0146] If the number of target personnel in the personnel information corresponding to the air conditioning operating area is equal to the second number threshold, then the air conditioning operating area is determined as an unmanned operating area.

[0147] Close the fresh air valve in the unmanned operating area and drive the target air conditioning unit corresponding to the unmanned operating area to draw in the target fresh air for treatment in the unmanned operating area;

[0148] The target air conditioning unit is driven to use the target treated fresh air to regulate the air quality of other air-conditioned operating areas.

This achieves improved energy utilization efficiency and reduced energy waste caused by the multi-split air conditioning unit when the fresh air mode is activated, thereby achieving better air conditioning energy-saving effects.
