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

[0055] At present, with the rapid development of air conditioning technology, more and more air conditioners are beginning to be equipped with fresh air modules. For example, multi-split air conditioners installed in commercial places or other places with high population density need to be equipped with fresh air modules to introduce outdoor fresh air to adjust indoor air quality requirements. However, the existing multi-split air conditioners in places with high population density cannot properly adjust the fresh air volume of each air conditioning operation area, resulting in high fresh air load and energy consumption, and energy waste, which makes the energy-saving effect of the air conditioner poor and cannot meet the existing energy-saving operation requirements of the air conditioner.

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

[0057] The air conditioning control method in the embodiment of the present invention is applied to an air conditioning control device, which is arranged in an air conditioner. The air conditioner is provided with one or more processors, a memory, and one or more applications, wherein the one or more applications are stored in the memory and configured to be executed by the processor to implement the air conditioning control method; wherein the air conditioner can be a multi-split intelligent air conditioner, such as a mobile air conditioner, a window air conditioner, a wall air conditioner, a cabinet air conditioner, a central air conditioner, and the like.

[0058] like Figure 1 As shown, Figure 1 This is a scene diagram of the air-conditioning control method of an embodiment of the present application. The air-conditioning control scene in the embodiment of the present invention includes an air conditioner 100 (an air-conditioning control device is integrated in the air conditioner 100), and a computer-readable storage medium corresponding to the air-conditioning control method is running in the air conditioner 100 to execute the steps of the air-conditioning control method.

[0059] Understandably, Figure 1The air conditioner in the air conditioning control method scenario shown, or the devices included in the air conditioner, does not constitute a limitation on the embodiments of the present invention, that is, the number of air conditioner devices and types of devices included in the air conditioning control method scenario, or the number of devices and types of devices included in each device, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be regarded as equivalent replacements or derivatives of the technical solution claimed to be protected in the embodiments of the present invention.

[0060] The air conditioner 100 in the embodiment of the present invention is mainly used to: respond to a multi-split air conditioner control request and collect a regional image stream corresponding to the air conditioner operation area of ​​the target air conditioner unit;

[0061] Performing image recognition on the regional image stream to determine personnel information of each air-conditioning operation area in the regional image stream;

[0062] The target fresh air volume of each air-conditioning operation area is determined according to the personnel information, and the target air-conditioning unit is driven to adjust the air quality of the air-conditioning operation area according to the target fresh air volume.

[0063] The air conditioner 100 in the embodiment of the present invention may be a multi-split air conditioner with a fresh air conditioning function, which includes at least one mobile air conditioner, a window air conditioner, a wall air conditioner, a cabinet air conditioner, and other intelligent air conditioners. In addition, the air conditioner may also be a central air conditioner.

[0064] The embodiments of the present application provide an air conditioning control method, apparatus, device, and computer-readable storage medium, which are described in detail below.

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

[0066] It should be noted that Figure 1 The scene diagram of the air-conditioning control method shown is only an example. The scene of the air-conditioning control method described in the embodiment of the present invention is to more clearly illustrate the technical solution of the embodiment of the present invention, and does not constitute a limitation on the technical solution provided by the embodiment of the present invention.

[0067] Based on the scenario of the above air-conditioning control method, various embodiments of the air-conditioning control method disclosed in the present invention are proposed.

[0068] like Figure 2 As shown, Figure 2 This is a flow chart of an embodiment of an air conditioning control method in an embodiment of the present application. The air conditioning control method includes the following steps 201 to 203:

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

[0070] The air conditioning control method in this embodiment is applied to air conditioners, and 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 adjustment function (wherein the target air-conditioning unit can be any one or more of mobile 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 set one or more indoor units in different indoor areas of the building, so as to achieve multi-connection adjustment of different indoor areas of the building. The indoor area of ​​the building can be any indoor area of ​​a building such as a residence, a shopping mall, an office building, and a factory. For example, in a specific embodiment, the air conditioner can be set in a high-density crowd building such as a shopping mall, wherein each target air-conditioning unit in the air conditioner is correspondingly set in a shopping mall area of ​​the mall, and because the flow of people in the shopping mall building is large and the flow of people varies greatly, the air conditioner also needs to dynamically adjust the fresh air volume according to 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 the fresh air utilization rate and energy-saving effect of the air conditioner.

[0072] Specifically, during operation, the air conditioner responds to a multi-connection air conditioning control request, wherein the multi-connection air conditioning control request is an operation instruction for driving the air conditioner to perform dynamic fresh air control according to the personnel information corresponding to each target air conditioning unit in the air conditioner. Optionally, the triggering method of the multi-connection air conditioning control request is not specifically limited here, that is, the multi-connection air conditioning control request can be actively triggered by the user, for example, the user actively triggers the multi-connection control request by clicking a fresh air control button set on a remote control device that is connected to the air conditioner for communication. In addition, the multi-connection control request can also be automatically triggered by the air conditioner, for example, the fresh air control process is pre-set in the air conditioner, and the multi-connection control request is automatically triggered within a preset time period.

[0073] Specifically, after receiving the multi-connected air conditioning control request, the air conditioner determines the air conditioning operation area corresponding to each target air conditioning unit of the air conditioner, and collects the regional image stream of the air conditioning operation area corresponding to the target air conditioning unit. The air conditioning operation area is the indoor area where the target air conditioning unit performs air conditioning. Each target air conditioning unit corresponds to an air conditioning operation area. The regional image stream is a video stream of the air conditioning operation area obtained by shooting the air conditioning operation area when the target air conditioning unit is in operation.

[0074] Specifically, during the operation of the air conditioner, the target camera is used to collect video images of the air-conditioning operation area corresponding to each target air-conditioning unit, and the video images are set as the regional image stream of the air-conditioning operation area. The regional image stream can reflect the personnel activity information (such as personnel flow and personnel activity status, etc.) in the air-conditioning operation area.

[0075] Optionally, the target camera may be a camera installed in the target air conditioning unit, or the target air conditioning unit may communicate with a surveillance camera in the air conditioning operation area through an Internet of Things communication link, and the surveillance camera may be used as the target camera. The target camera may 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 personnel information of each air-conditioning operation area in the regional image stream;

[0077] Specifically, after the air conditioner obtains the regional image stream corresponding to the air conditioning operation area of ​​each target air conditioning unit, it also performs image recognition on the regional image stream, thereby determining the personnel information of each air conditioning operation area in the regional image stream. The personnel information is parameter information characterizing the flow of people and the activity status of people in the air conditioning operation area. The personnel information may include the activity status information and object location information of the target person object. The activity status information is information characterizing the current activity status of the target person object, for example, the activity status information may be moving status information and stationary status information, etc.

[0078] Specifically, after the air conditioner obtains the regional image stream of each air-conditioning operation 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 for multiple images in the regional image stream.

[0079] Specifically, after acquiring the initial background image stream, the air conditioner also performs background update on the background image stream according to the regional image stream to obtain an updated background image stream. That is, the air conditioner acquires the first initial image and the second initial image in the regional image stream to perform background update on the regional image stream, thereby obtaining the regional image stream. Among them, the first initial image is the scene image information in the regional image stream data acquired at the previous moment, and the second initial image is the scene image information of the regional image stream data acquired at the current moment. That is, 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 the air conditioner obtains the regional image stream of each air-conditioning operation area, it performs background segmentation processing on the regional image stream to obtain a first background image in the initial video stream 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 also initializes the first background image to obtain the initialized first background image, and compares the first background image with the current second background image of the regional image stream to obtain a comparison result, and adjusts the regional image stream according to the comparison result to obtain the regional image stream, thereby reducing the result error caused by scene changes.

[0082] Optionally, if the comparison result is that the similarity between the first background image and the second background image is greater than or equal to a preset similarity threshold, 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 is 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 regional image stream, thereby determining the personnel information of each air-conditioning operation area in the regional image stream.

[0085] Specifically, the air conditioner uses the updated background image stream to perform image segmentation on the image stream of the area, obtains the foreground image stream in the image stream of the area, and inputs the foreground image stream into a preset image recognition model for image recognition, thereby determining the object position information and activity status information of each target person object 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 a target fresh air volume for each air-conditioning operation area according to the personnel information, and drive the target air-conditioning unit to adjust the air quality of the air-conditioning operation area according to the target fresh air volume.

[0087] Specifically, after determining the personnel information of each air-conditioning operation area, the air conditioner also determines the target fresh air volume of each air-conditioning operation area according to the personnel information, and drives the target air-conditioning unit to adjust the air quality of the air-conditioning operation 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-conditioning operation area according to the target fresh air volume, so as to perform air conditioning on the air-conditioning operation area and improve the regional comfort of the air-conditioning operation area.

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

[0089] Optionally, the air conditioner is pre-set with a first threshold for detecting the flow of people in the air conditioner operation area, and the first threshold is compared with the target number of people, and the target fresh air volume of the air conditioner operation area is determined according to the comparison result. The first threshold is a threshold for the number of people determined by the minimum fresh air volume that characterizes the commercial building to meet the hygiene requirements of the personnel.

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

[0091] Optionally, if the target number of people in the air-conditioning operation area is less than the first number threshold, the fresh air valve opening of the target air-conditioning unit corresponding to the air-conditioning operation area is reduced according to the activity status information of each target person object, so as to obtain the target fresh air volume of the air-conditioning operation area. That is, after determining that the target number of people in the air-conditioning operation 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 according to the activity status information of each target person object. If the activity status information is leaving the active state, the air conditioner subtracts the number of people whose activity status information is leaving the active state from the difference, obtains the target number difference, and queries the preset control database to determine the fresh air volume corresponding to the target number difference, and determines the fresh air volume as the target fresh air volume of the air-conditioning operation area, and reduces the introduction of outdoor fresh air according to the target fresh air volume to adjust the air quality of the air-conditioning operation area.

[0092] Optionally, in other embodiments, the air conditioner can also directly determine the corresponding target fresh air volume according to the target number of people in the air-conditioning operation area, thereby reducing the calculation burden of the air conditioner.

[0093] Optionally, in other embodiments, when the target number of people in the air-conditioning operation area reaches a second number threshold, the air conditioner also performs an air backdraft operation on the air-conditioning operation area, thereby introducing processed fresh air and refrigerated air or heated air into other air-conditioning operation areas, thereby reducing the energy consumption of the air conditioner and the waste of fresh air.

[0094] In this embodiment, the air conditioner collects the regional image stream of the air-conditioning operation area corresponding to the target air-conditioning unit by responding to the multi-split air-conditioning control request; performs image recognition on the regional image stream to determine the personnel information of each air-conditioning operation area in the regional image stream; determines the target fresh air volume of each air-conditioning operation area according to the personnel information, and drives the target air-conditioning unit to adjust the air quality of the air-conditioning operation area according to the target fresh air volume. By dynamically adjusting the target fresh air volume of each air-conditioning operation area according to the activity status of the personnel in the air-conditioning operation area corresponding to the air-conditioning unit, driving the target air-conditioning unit to adjust the air quality in each air-conditioning operation area according to the target fresh air volume, the energy utilization rate of the air conditioner is improved, and the energy waste caused by the multi-split air conditioner when the fresh air mode is turned on is reduced, thereby achieving a better air-conditioning energy-saving effect.

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

[0096] 301. Extracting portrait features based on the updated background image stream and the regional image stream using a preset target extraction model to obtain target image features;

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

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

[0099] 304. Position and identify the target person object to obtain personnel information of each air-conditioning operation area, where the personnel information includes activity status information and object location information of the target person object.

[0100] Based on the above embodiments, in this embodiment, after acquiring the updated background image stream, the air conditioner 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 operation area in the regional image stream.

[0101] Specifically, a target extraction model for extracting features from an updated background image stream and a regional image stream is pre-set in the air conditioner. The air conditioner inputs the updated background image stream and the regional image stream into the target extraction model, and utilizes the target extraction model to extract portrait features based on the updated background image stream and the regional image stream to obtain target image features. That is, after acquiring 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 regional image stream based on the updated background features to obtain a foreground image stream of the regional image stream. The target extraction model further performs portrait feature extraction on the foreground image stream to obtain target image features, wherein the target image features are image feature information characterizing each object in the regional image stream.

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

[0103] Optionally, if the predicted probability of a portrait of any of the candidate detection objects is greater than or equal to a preset probability threshold, the candidate detection object is determined as a target person object. The preset probability threshold is similarity threshold information that characterizes whether the candidate detection object is a human being. After acquiring the target person object in the air-conditioning operation area, the air conditioner further locates and identifies the target person object to obtain the personnel information of each of the air-conditioning operation areas, and the personnel information includes the activity status information and object location information of the target person object.

[0104] Optionally, the air conditioner locates and identifies the target person object to obtain the initial position information of the target person object. Further, in order to determine the accuracy of the initial position information, the air conditioner also calculates the position stay time of the initial position information, and compares the position stay time with a preset time threshold, thereby determining the validity of the initial position information.

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

[0106] Specifically, after obtaining the object position information of the target person object in each air-conditioning operation area, the air conditioner further identifies the activity state information of the target person object, that is, the air conditioner determines the activity intention of the target person object based on the image information of several frames in the regional image stream, determines the activity intention as the activity state information of the target person object, and summarizes the activity state information and object position information of each target person object to obtain the personnel information of each air-conditioning operation area. The activity state information includes the stay state information and the movement state information.

[0107] Specifically, after determining the personnel information of each air-conditioning operation area, the air conditioner also determines the target fresh air volume of each air-conditioning operation area according to the personnel information, and drives the target air-conditioning unit to adjust the air quality of the air-conditioning operation 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-conditioning operation area according to the target fresh air volume, so as to perform air conditioning on the air-conditioning operation area and improve the regional comfort of the air-conditioning operation area.

[0108] In this embodiment, the air conditioner extracts portrait features based on the updated background image stream and the regional image stream by using a preset target extraction model to obtain target image features; performs image detection on the target image features to obtain each candidate detection object in the target image features; if the portrait prediction probability of any candidate detection object is greater than or equal to a preset probability threshold, the candidate detection object is determined as a target person object; locates and identifies the target person object to obtain personnel information in each air conditioning operation area, and the personnel information includes the activity status information and object location information of the target person object. Accurately identify the personnel information of each air conditioning operation area in a multi-split fresh air air conditioner, and provide a data basis for the subsequent dynamic adjustment of the fresh air volume in each air conditioning operation area.

[0109] like Figure 4 As shown, Figure 4 This is a flow chart of an embodiment of determining the target fresh air volume in the air conditioning control method provided in the embodiment of the present 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 operation area is equal to a second number threshold, the air-conditioning operation area is determined as an unmanned operation area;

[0111] 402. Close the fresh air valve in the unmanned operation area, and drive the target air conditioning unit corresponding to the unmanned operation area to absorb the target processed fresh air in the unmanned operation area;

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

[0113] Based on the above embodiment, in this embodiment, when the number of target people in the air-conditioning operation area reaches the second number threshold, the air-conditioning device also performs an air back-suction operation on the air-conditioning operation area, thereby introducing the processed fresh air and the refrigerated air or the heated air into other air-conditioning operation areas, thereby reducing the energy consumption of the air-conditioning device and the waste of fresh air. 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-conditioning operation area in real time. When the number of target personnel in the personnel information corresponding to the air-conditioning operation area is equal to the second number threshold, the air conditioner determines that there are no people in the air-conditioning operation area and determines the air-conditioning operation area as an unmanned operation area.

[0115] Optionally, in other embodiments, in order to improve control accuracy, the air conditioner further calculates the duration that the target number of people is equal to the second number threshold, and only when the duration exceeds the preset duration threshold is the air conditioner operation area determined as an unmanned operation area, thereby avoiding misjudgment affecting the normal activities of people.

[0116] Specifically, after the air conditioner determines that there is an unmanned operating area, the air conditioner closes the fresh air valve in the unmanned operating area, as well as the indoor cooling or indoor heating function in the unmanned operating area. Since the air in the unmanned operating area at this time is the target processed fresh air that has been processed, in order to avoid wasting this part of the target processed fresh air, the air conditioner also drives the indoor fan of the target air-conditioning unit corresponding to the unmanned operating area to reverse the setting, so that the indoor fan is used to absorb the target processed fresh air and send it to the target air duct, and drives the target air-conditioning unit to use the target processed fresh air to mix it with the processed air in other air-conditioning operating areas, and uses the mixed air to adjust the air quality of other air-conditioning operating areas, thereby driving the target air-conditioning unit to use the target processed fresh air to adjust the air quality of other air-conditioning operating areas, so as to reduce the fresh air energy consumption of other units, thereby reducing air conditioning energy consumption.

[0117] In this embodiment, when the air conditioner determines that the number of target personnel in the personnel information corresponding to the air-conditioning operation area is equal to the second number threshold, the air-conditioning operation area is determined as an unmanned operation area; the fresh air valve in the unmanned operation area is closed, and the target air-conditioning unit corresponding to the unmanned operation area is driven to absorb the target processed fresh air in the unmanned operation area; the target air-conditioning unit is driven to use the target processed fresh air to adjust the air quality of other air-conditioning operation areas. When the air-conditioning operation area is in an unmanned state, the processed target processed fresh air in the area is transmitted to other air-conditioning operation areas with people, thereby reducing the fresh air energy consumption of the air conditioner.
