Description

Technical Field

[0001] This invention relates to the field of air conditioning control technology, specifically to an air conditioning control method, device, air conditioner, and storage medium. Background Technology

[0002] Air conditioners require a relatively enclosed indoor space to operate effectively and achieve optimal temperature control. However, when the space is enclosed, poor air circulation leads to a decrease in indoor oxygen levels, causing discomfort such as chest tightness for users. While some air conditioners incorporate a fresh air module to introduce fresh outdoor air and increase oxygen levels, excessive introduction of outdoor air reduces the air conditioner's temperature control effectiveness and overall comfort. Therefore, air conditioning does not necessarily provide high levels of comfort. Summary of the Invention

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, in the description of the embodiments of the present invention, the terms "first," "second," etc., are only used for distinguishing descriptions and should not be construed as indicating or implying relative importance. Therefore, features defined with "first" or "second" may explicitly or implicitly include one or more features. In the description of the embodiments of the present invention, "multiple" means two or more, unless otherwise explicitly specified.

[0047] This invention provides an air conditioning control method, apparatus, air conditioner, and computer-readable storage medium.

[0048] Specifically, this embodiment will be described from the perspective of the air conditioner control device, which can be integrated into the air conditioner. That is, the air conditioner control method of this embodiment can be executed by the air conditioner.

[0049] The following detailed description is provided in conjunction with the accompanying drawings. In this embodiment, an air conditioner is used as the executing entity. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments. Although a logical order is shown in the flowcharts, in some cases, the steps shown or described may be performed in a different order than that shown in the accompanying drawings.

[0050] According to the background art description of the present invention, an air conditioner is equipped with a fresh air module, which can introduce fresh outdoor air into the room, thereby increasing the indoor oxygen content. However, excessive introduction of outdoor air reduces the air conditioner's temperature regulation effect and also reduces indoor comfort. Therefore, the comfort of the air conditioner is not high.

[0051] To address the above problems, this invention discloses a method for controlling an air conditioner. Please refer to [reference needed]. Figure 1 The specific flow of the air conditioner control method can be summarized in steps S10 to S40, wherein:

[0052] Step S10: Obtain the biometric information and movement status of the target object in the indoor environment where the air conditioner is located, as well as the indoor oxygen content and outdoor oxygen content;

[0053] In this embodiment, the air conditioner consists of an indoor unit and an outdoor unit. The indoor unit is located in the indoor environment, which is the space where the air conditioner operates. Therefore, the operation of the air conditioner will affect the indoor environment. The target object is located in the indoor environment and can sense changes in the indoor environment, thus affecting the target object. The target object can be a user, a pet, or other living organism capable of sensing changes in the indoor environment. Therefore, the target object in the indoor environment possesses biological characteristics, including age, height, weight, and gender. The data corresponding to these biological characteristics constitutes the biometric information. The biometric information can be obtained through a terminal application associated with the air conditioner, acquiring the biometric information input by the user, or through the air conditioner's imaging device, acquiring images of the target object in the indoor environment, and obtaining the target object's biometric information based on the images. Since the target object possesses certain biometric information, it also has a certain degree of mobility. The movement state of the target object can be acquired, and the movement state can characterize the intensity of the target object's movement.

[0054] In this embodiment, an oxygen detection device can be installed in both the indoor and outdoor units of the air conditioner. The oxygen detection device can be an oxygen sensor chip, etc. The oxygen detection device on the indoor unit can detect the indoor oxygen content in real time, and the oxygen detection device on the outdoor unit can detect the outdoor oxygen content in real time.

[0055] In this embodiment, after the air conditioner has been running for a preset time, that is, after the indoor environment has been in a closed state for a long time and the indoor oxygen content has decreased, step S10 is executed to obtain the biological characteristics and movement status of the target object in the indoor environment at the current moment, as well as the indoor oxygen content and outdoor oxygen content.

[0056] Step S20: Determine the indoor oxygen demand based on the biometric information and the movement status;

[0057] In this embodiment, different biometric information of the target object leads to different oxygen requirements. The oxygen content that makes the target object feel comfortable is related to the target object's age, height, weight, gender, etc., with different biometric information resulting in different oxygen needs. The target object's movement state is mostly changed by spontaneous activities, such as sleeping, lying down, or running. Different movement states require different oxygen levels; for example, high-intensity exercise like running requires more oxygen, while low-intensity exercise like sleeping or lying down requires less. Therefore, the target object's biometric information and movement state information can determine the target object's oxygen requirement, and thus determine the indoor oxygen demand of the indoor environment where the target object is located. Based on mapping relationships or calculation formulas, the biometric information and movement state can be processed to obtain the indoor oxygen demand.

[0058] Step S30: Determine the target fresh air volume of the fresh air module based on the indoor oxygen content, outdoor oxygen content, and indoor oxygen demand;

[0059] In this embodiment, based on the indoor oxygen content and indoor oxygen demand, the oxygen difference required to achieve a suitable indoor environment for the target object can be determined. The oxygen difference represents the amount of oxygen that is lacking indoors and needs to be introduced. This oxygen can be introduced from the outdoor environment. The outdoor oxygen content is determined, and the target fresh air volume needs to be introduced based on the current outdoor oxygen content to make up for the lack of oxygen indoors. Furthermore, the spatial volume of the indoor environment can be obtained to calculate the target fresh air volume more accurately.

[0060] It should be noted that indoor oxygen content, outdoor oxygen content, and indoor oxygen demand can all refer to the oxygen concentration per unit volume.

[0061] Step S40: Control the operation of the fresh air module according to the target fresh air volume.

[0062] In this embodiment, the air conditioner includes a fresh air module, which includes a fan. By controlling the fan to rotate, fresh outdoor air can be introduced into the room. The air introduced by the fresh air module is called fresh air. The fresh air volume represents the amount of air introduced into the room from the outside by the fresh air module. The fresh air volume introduced by the fresh air module can be adjusted by controlling the fan speed or the operating time of the fresh air module. In this way, the operation of the fresh air module can be controlled according to the target fresh air volume so that the fresh air module can introduce fresh air from the outside that meets the target fresh air volume, so that the oxygen content in the indoor environment reaches the indoor oxygen demand suitable for the target object.

[0063] In the technical solution disclosed in this embodiment, the biometric information and movement status of the target object in the indoor environment where the air conditioner is located, as well as the indoor and outdoor oxygen levels, are obtained; the indoor oxygen demand is determined based on the biometric information and movement status; the target fresh air volume of the fresh air module is determined based on the indoor oxygen level, outdoor oxygen level, and indoor oxygen demand; and the operation of the fresh air module is controlled based on the target fresh air volume. By obtaining the biometric information and movement status of the target object in the indoor environment, the appropriate indoor oxygen demand for the target object is determined, and the target fresh air volume that the fresh air module needs to introduce from the outside is determined based on the indoor oxygen level, outdoor oxygen level, and indoor demand. This accurately increases the indoor oxygen level to a concentration suitable for the target object's activities without excessively introducing fresh air, which would reduce the temperature control effect of the air conditioner and improve the comfort of the air conditioner.

[0064] Further, step S20 includes:

[0065] The biometric information is input into a preset data processing model to obtain the raw oxygen demand;

[0066] Based on the described motion state and the preset correspondence, the oxygen demand compensation coefficient is determined;

[0067] The indoor oxygen demand is determined based on the oxygen demand compensation coefficient and the original oxygen demand.

[0068] In this embodiment, biometric information is the main factor determining the oxygen demand of the target object. The difference in oxygen demand caused by different biometric information is greater than the difference in oxygen demand caused by different exercise states. Therefore, the original oxygen demand corresponding to the target object can be determined first based on the biometric information as the base for calculating the indoor oxygen demand. Then, the oxygen demand compensation coefficient is determined in combination with the exercise state of the target object to compensate for the original oxygen demand, thereby determining the suitable indoor oxygen demand for the target object and the target object's current exercise state.

[0069] Specifically, biometric information is multi-dimensional data, which may include information such as age, height, weight, gender, and species. Processing this information can be achieved using a pre-defined data processing model to improve accuracy and efficiency. This data processing model is pre-trained on multiple training samples to find the correlation between multi-dimensional biometric information and raw oxygen demand (ROD). The training samples include multiple different biometric information items labeled with ORD. The current biometric information is input into the trained data processing model, which then predicts the ROD of the target object based on the biometric information. Optionally, the data processing model can employ the KNN algorithm. For a new sample to be classified (i.e., the currently input biometric information), it finds the K closest training samples. Based on the labels of these K samples, a regression problem is used to determine the predicted value of the sample to be classified. During the model training phase, the training set is used to build the KNN model, and then the test set is used to evaluate the model's performance and generalization ability.

[0070] After processing biometric information using a data processing model, the raw oxygen demand (ROD) of the target object is obtained. Based on the movement state and a preset correspondence between movement state and oxygen demand compensation coefficient, the oxygen demand compensation coefficient corresponding to the raw ORD is determined. The preset correspondence can be:

[0071] motion state Oxygen demand compensation coefficient Static or bed rest 1.2 Light activity or light exercise 1.375 Moderate activity or moderate exercise 1.55 High activity or high-intensity exercise 1.725 Extreme activity or very high-intensity exercise 1.9

[0072] The oxygen demand compensation coefficient is an adjustment coefficient determined based on the exercise state to adjust the original oxygen demand. The original oxygen demand is linearly processed based on the oxygen demand compensation coefficient to obtain the determined indoor oxygen demand. It should be noted that because the oxygen content is slightly higher than the actual oxygen demand of the target object, the oxygen demand compensation coefficient in the table above is set relatively high. Based on the exercise state, the oxygen demand compensation coefficient can be fine-tuned according to needs; this embodiment does not impose any restrictions on this.

[0073] By processing biometric information through a pre-set data processing model, the original oxygen demand of the target object can be accurately and efficiently determined. Then, by combining the target object's movement state, an oxygen demand compensation coefficient can be determined to compensate for the original oxygen demand, resulting in an indoor oxygen demand that is more suitable for the target object and its current movement state. This allows the fresh air module to introduce a more appropriate amount of fresh air, further improving the comfort of the air conditioning.

[0074] Furthermore, before inputting the biometric information into a preset data processing model to obtain the raw oxygen demand, the process further includes:

[0075] Obtain the operation feedback information of the fresh air module corresponding to the same model of the air conditioner in the target area corresponding to the air conditioner;

[0076] The target oxygen demand of the target air conditioner corresponding to the target object is determined based on the operational feedback information.

[0077] Based on the biometric information of the target object corresponding to the target air conditioner and the target oxygen demand, the initial data processing model is updated to obtain the data processing model.

[0078] In this embodiment, the training samples used to train the data processing model can come from other target air conditioners of the same model in the same region where the current air conditioner is located. There are several target air conditioners, and several data points can be collected accordingly. The oxygen demand of the target objects corresponding to the target air conditioners in the same region tends to be the same. The target air conditioners involved in this embodiment are of the same model and also have a fresh air module. The operational feedback information of the target objects corresponding to the target air conditioners on the corresponding fresh air module is obtained. The operational feedback information is the feedback of the target objects on the operation effect of the fresh air module. For example, if the target object feels dizzy when the fresh air module is running at a target fresh air volume of XX, it indicates that the indoor oxygen demand corresponding to the target object is too low. Therefore, the indoor oxygen demand can be increased to obtain the target oxygen demand. In this way, the operational feedback information can determine the target oxygen demand of the target object corresponding to the target air conditioner. Based on the biometric information of the target objects corresponding to several target air conditioners of the same model, and the target demand of the target objects, the data processing model is further trained to update the initial data processing model and obtain the data processing model. Based on the data processing model, the original oxygen demand of the target objects in the indoor environment where the air conditioner is located can be determined more accurately, thereby improving the accuracy of the target fresh air volume and improving the comfort of the air conditioner.

[0079] Further, step S40 includes:

[0080] Obtain outdoor and indoor ambient temperatures;

[0081] The fan speed of the fresh air module is determined based on the temperature difference between the outdoor ambient temperature and the set temperature.

[0082] The operating time of the fresh air module is determined based on the fan speed and the target fresh air volume, and the operation of the fresh air module is controlled based on the operating time and the fan speed.

[0083] In this embodiment, when the fresh air conditioner introduces fresh air, the indoor ambient temperature will fluctuate. This fluctuation is related to the indoor-outdoor temperature difference and the amount of fresh air introduced by the fresh air module per unit time. The greater the indoor temperature difference and the greater the amount of fresh air introduced by the fresh air module per unit time, the greater the fluctuation in indoor ambient temperature, leading to a decrease in indoor comfort. Therefore, after determining the target fresh air volume to be introduced by the fresh air module, the outdoor and indoor ambient temperatures are obtained. Based on the temperature difference between the outdoor and indoor ambient temperatures, the maximum fresh air volume introduced by the fresh air module per unit time that is unlikely to cause fluctuations in the indoor ambient temperature is determined. The fresh air volume introduced by the fresh air module per unit time is related to the fan speed of the fresh air module. The higher the fan speed, the greater the fresh air volume introduced by the fresh air module per unit time. Since the correspondence between the fan speed of the fresh air module and the temperature difference between the outdoor and indoor ambient temperatures can be determined in advance, the fan speed corresponding to the current temperature difference between the outdoor and indoor ambient temperatures is determined based on this relationship. Based on the determined fan speed and target fresh air volume, the operating time of the fresh air module is determined. The calculation formula can be: Operating time = Target fresh air volume / K·Fan speed, where K is the conversion coefficient between fan speed and the fresh air volume introduced by the fresh air module per unit time. Then, the fan speed of the fresh air module is controlled to rotate until the operating time is reached. After the operating time is reached, the fresh air module can be shut down.

[0084] By determining the appropriate fan speed for the fresh air module based on the temperature difference between the outdoor and indoor environments, excessive indoor temperature fluctuations can be avoided. Furthermore, the fresh air module can be operated according to the fan speed and operating time to introduce fresh air that meets the target volume while avoiding indoor temperature fluctuations, thereby further improving the comfort of the air conditioning.

[0085] Optionally, refer to Figure 2 Based on any of the above embodiments, in another embodiment of the air conditioner control method of the present invention, step S10 includes:

[0086] Step S11: Acquire indoor images using a camera;

[0087] In this embodiment, the indoor unit of the air conditioner also includes a camera device, which captures images of the indoor environment to obtain indoor images. If the indoor environment includes a target object, images of the target object are also captured.

[0088] Step S12: Input the indoor image into the image recognition model to determine the identity information and corresponding posture information in the indoor image;

[0089] In this embodiment, an indoor image is input into an image recognition model, which includes a first recognition module and a second recognition module. The first recognition module identifies whether the indoor image contains an image of a target object. If not, it inputs a result indicating no target object, eliminating the need to control the fresh air module and thus saving energy. If the target object is present, it inputs the image features corresponding to the target object's image into the second recognition module. The second recognition module identifies the target object's posture based on the image features, obtaining the target object's posture information and identity information.

[0090] Step S13: Determine the motion state based on the heart rate information corresponding to the posture information and the identity information.

[0091] In this embodiment, the current posture of the target object can be determined based on posture information. The target object's posture varies depending on its movement state; for example, when the target object is running, it adopts a standing posture, while when it is lying down, it adopts a sitting posture. In addition to posture information, the target object's heart rate information also needs to be obtained based on its corresponding identity information. The heart rate information differs depending on the target user's movement state; a higher heart rate indicates potentially greater exercise intensity, while a lower heart rate indicates potentially less intense exercise. Combining heart rate and posture information allows for a more accurate determination of the target object's movement state, avoiding misjudgments based solely on posture or heart rate information in special circumstances.

[0092] Optionally, obtaining the target object's heart rate information based on the target object's identity information can be achieved by obtaining the connection information of the smart device worn by the target object corresponding to the identity information, including the connection account and connection code, and establishing a communication connection with the smart device worn by the target object based on the connection information. The smart device is a device worn by the target object that can collect the target object's heart rate, such as a smartwatch. The heart rate information of the target object collected by the smart device is then obtained based on the communication connection.

[0093] In the technical solution disclosed in this embodiment, an indoor image is acquired using a camera; the indoor image is input into an image recognition model to determine the identity information and posture information of the target object in the indoor image; and the motion state is determined based on the posture information and the heart rate information corresponding to the identity information. In this way, the identity information and posture information of the target object can be quickly determined from the indoor image, and the corresponding heart rate information can be obtained based on the identity information as the target object's heart rate information. Combining the heart rate information and posture information allows for a more accurate determination of the target object's motion state, thereby more accurately determining the indoor oxygen demand and further improving the comfort of the air conditioning.

[0094] Optionally, refer to Figure 3Based on any of the above embodiments, in another embodiment of the air conditioner control method of the present invention, step S20 further includes:

[0095] Step S21: If there are multiple target objects in the indoor environment, obtain the historical operation frequency and historical operation type of each target object on the fresh air module;

[0096] In this embodiment, if there are multiple target objects in the indoor environment where the air conditioner is located, it is necessary to set an appropriate indoor oxygen demand based on the oxygen demand of these target objects to better balance the oxygen needs of each target object and the temperature control needs of the indoor environment. Each target object can control various modules of the air conditioner through its own air conditioner control program, including the control of the fresh air conditioning. For example, user A can log in to the air conditioner control program through a smart terminal to log in to the account corresponding to their identity information to control the air conditioner, and user B can also log in to the air conditioner control program through a smart terminal to log in to the account corresponding to their identity information. In this way, the control information of different target objects on the air conditioner can be obtained. Among them, the historical control information of each target object on the fresh air module of the air conditioner in the current indoor environment is obtained, including the historical operation frequency and historical operation type of the fresh air module. When the historical operation frequency is high, it indicates that the target object is not satisfied with the self-operation of the fresh air module. Conversely, when the historical operation frequency is low, it indicates that the target object is satisfied with the self-operation of the fresh air module. The fresh air module operates with the target fresh air volume calculated during the historical operation process, which can meet its oxygen demand. The operation priority of target objects with low historical operation frequency can be set higher to better meet the oxygen demand of these target objects. Historical operation types indicate the types of control commands issued by the target object to the fresh air model. If the historical operation type is not an adjustment of the fan speed or running time of the fresh air module, that is, not an adjustment of the target fresh air volume, such as adjusting the humidity of the fresh air input to the fresh air module, it indicates that the target object is highly satisfied with the fresh air module operating at the target fresh air volume. The operation priority of the target object with this type of historical operation type can be set higher to better meet the oxygen demand of this target object.

[0097] Step S22: Determine the operation priority corresponding to each target object based on the historical operation frequency and the historical operation type;

[0098] In this embodiment, both historical operation frequency and historical operation type can be used as the basis for setting the operation priority of the target object. In this way, the operation priority of each target object can be determined by combining the historical operation frequency and historical operation type of each target object. This multi-dimensional setting of operation priority can better meet the needs of each target object.

[0099] Step S23: Determine the indoor oxygen demand based on the operation priority corresponding to each target object, the biological characteristic information of each target object, and the movement state.

[0100] In this embodiment, the operation priority can represent the target object's satisfaction with the fresh air module. A higher operation priority indicates greater satisfaction with the module's automatic operation, leading to a more satisfactory automatically determined oxygen demand for the target object, thus better aligning with their oxygen requirements. Based on the biological characteristics and movement status of each target object, their oxygen demand can be determined. The top n target objects are ranked according to their operation priority, and the indoor oxygen demand is determined based on their oxygen demand. Alternatively, the operation weight for each target object can be determined based on its operation priority, and the oxygen demand of each target object can be weighted according to its operation weight, with the weighted result used as the indoor oxygen demand.

[0101] In the technical solution disclosed in this embodiment, if there are multiple target objects in the indoor environment where the air conditioner is located, the operation priority of each target object can be determined according to the historical operation frequency and historical operation type of the target object to the fresh air module. Then, combined with the biological characteristic information and movement state of each target object, an indoor oxygen demand that can balance the oxygen demand of each target object and the temperature regulation demand of the indoor environment can be set to further improve the comfort of the air conditioner.

[0102] Optionally, based on any of the above embodiments, in another embodiment of the air conditioner control method of the present invention, before step S30, the method further includes:

[0103] Step S50: If the outdoor oxygen content is less than the indoor oxygen demand, then determine the oxygen production capacity of the oxygen generating module based on the indoor oxygen demand and the outdoor oxygen content.

[0104] Step S60: Control the operation of the oxygen generation module according to the oxygen generation capacity.

[0105] In this embodiment, the oxygen difference is first determined based on the indoor oxygen content and the indoor oxygen demand. Then, the target fresh air volume of the fresh air module is determined based on the outdoor oxygen content. However, since oxygen concentration does not increase out of thin air, the indoor oxygen content is at most equal to the outdoor oxygen content. Introducing fresh air will not increase the indoor oxygen content. Therefore, the air conditioner can also include an oxygen generating module. If the outdoor oxygen content is less than the indoor oxygen demand, the oxygen supply of the oxygen generating module can be determined based on the oxygen difference between the indoor oxygen demand and the outdoor oxygen content. This allows the oxygen generating module to supply oxygen to the indoor environment, so that the oxygen content in the indoor environment reaches a comfortable level, reducing the operation of the fresh air module and ensuring the temperature control effect of the air conditioner.

[0106] Optionally, due to the high cost of oxygen production, the oxygen production module and the fresh air module can operate synchronously. If the outdoor oxygen content is less than the indoor oxygen demand, the oxygen production capacity of the oxygen production module is determined based on the indoor oxygen demand and the outdoor oxygen content. Then, the target fresh air volume of the fresh air module is determined based on the oxygen difference between the outdoor and indoor oxygen contents. The oxygen production equipment is then controlled based on this oxygen production capacity, and the fresh air module is controlled based on the target fresh air volume. This synchronous operation of the oxygen production equipment and the fresh air module can reduce oxygen production costs, improve oxygenation efficiency, and further enhance the comfort of the air conditioning system.

[0107] This embodiment also provides an air conditioner control device, which can be specifically integrated into the air conditioner. For example, such as... Figure 4 As shown, the control device for the air conditioner may include:

[0108] The acquisition unit 1001 is used to acquire the biometric information and movement status of the target object in the indoor environment where the air conditioner is located, as well as the indoor oxygen content and outdoor oxygen content.

[0109] The first determining unit 1002 is used to determine the indoor oxygen demand based on the biological characteristic information and the movement state;

[0110] The second determining unit 1003 is used to determine the target fresh air volume of the fresh air module based on the indoor oxygen content, outdoor oxygen content and indoor oxygen demand;

[0111] Control unit 1004 is used to control the operation of the fresh air module according to the target fresh air volume.

[0112] Optionally, the first determining unit 1002 is further configured to input the biometric information into a preset data processing model to obtain the raw oxygen demand;

[0113] Based on the described motion state and the preset correspondence, the oxygen demand compensation coefficient is determined;

[0114] The indoor oxygen demand is determined based on the oxygen demand compensation coefficient and the original oxygen demand.

[0115] Optionally, the first determining unit 1002 is further configured to obtain the operation feedback information of the fresh air module corresponding to the same model of the target air conditioner in the target area corresponding to the air conditioner;

[0116] The target oxygen demand of the target air conditioner corresponding to the target object is determined based on the operational feedback information.

[0117] Based on the biometric information of the target object corresponding to the target air conditioner and the target oxygen demand, the initial data processing model is updated to obtain the data processing model.

[0118] Optionally, the acquisition unit 1001 is also used to acquire indoor images via the imaging device;

[0119] The indoor image is input into an image recognition model to determine the identity and posture information of the target object in the indoor image;

[0120] The movement state is determined based on the heart rate information corresponding to the posture information and the identity information.

[0121] Optionally, the first determining unit 1002 is further configured to, if there are multiple target objects in the indoor environment, obtain the historical operation frequency and historical operation type of each target object on the fresh air module;

[0122] Based on the historical operation frequency and the historical operation type, determine the operation priority corresponding to each target object;

[0123] The indoor oxygen demand is determined based on the operation priority corresponding to each target object, the biometric information of each target object, and the motion state.

[0124] Optionally, the control unit 1004 is further configured to control the operation of the fresh air module according to the target fresh air volume, including:

[0125] Obtain outdoor and indoor ambient temperatures;

[0126] The fan speed of the fresh air module is determined based on the temperature difference between the outdoor ambient temperature and the indoor ambient temperature.

[0127] The operating time of the fresh air module is determined based on the fan speed and the target fresh air volume, and the operation of the fresh air module is controlled based on the operating time and the fan speed.

[0128] Optionally, before determining the target fresh air volume of the fresh air module based on the indoor oxygen content, outdoor oxygen content, and indoor oxygen demand, the control unit 1004 further includes:

[0129] If the outdoor oxygen content is less than the indoor oxygen demand, then the oxygen production capacity of the oxygen generating module is determined based on the indoor oxygen demand and the outdoor oxygen content.

[0130] The oxygen generation module is controlled to operate according to the oxygen production capacity.

[0131] In this embodiment, the biometric information and movement status of the target object in the indoor environment where the air conditioner is located, as well as the indoor and outdoor oxygen levels, are acquired. The indoor oxygen demand is determined based on the biometric information and movement status. The target fresh air volume of the fresh air module is determined based on the indoor oxygen level, outdoor oxygen level, and indoor oxygen demand. The operation of the fresh air module is controlled based on the target fresh air volume. By acquiring the biometric information and movement status of the target object in the indoor environment, the appropriate indoor oxygen demand for the target object is determined. The target fresh air volume that the fresh air module needs to introduce from the outside is then determined based on the indoor oxygen level, outdoor oxygen level, and indoor demand. This precisely increases the indoor oxygen level to a concentration suitable for the target object's activity without excessively introducing fresh air, which could reduce the air conditioner's temperature control effect and improve comfort.

Those skilled in the art will understand that the air conditioner structure shown in the figure does not constitute a limitation on the air conditioner, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0133] The processor 1101 is the control center of the air conditioner 1100. It connects various parts of the air conditioner 1100 via various interfaces and lines. By running or loading software programs and / or units stored in the memory 1102, and by calling data stored in the memory 1102, it executes various functions of the air conditioner 1100 and processes data, thereby performing overall monitoring of the air conditioner 1100. The processor 1101 can be a CPU, GPU, network processor (NP), etc., and can implement or execute the methods, steps, and logic diagrams disclosed in the embodiments of this invention.

[0134] In this embodiment of the invention, the processor 1101 in the air conditioner 1100 loads the instructions corresponding to the processes of one or more application programs into the memory 1102 according to the following steps, and the processor 1101 runs the application programs stored in the memory 1102 to realize various functions, such as:

[0135] Obtain the biometric information and movement status of the target object in the indoor environment where the air conditioner is located, as well as the indoor oxygen content and outdoor oxygen content;

[0136] Indoor oxygen demand is determined based on the biometric information and the movement status.

[0140] Optional, such as Figure 5 As shown, the air conditioner 1100 also includes: a touch screen display 1103, a radio frequency circuit 1104, an audio circuit 1105, an input unit 1106, and a power supply 1107. The processor 1101 is electrically connected to the touch screen display 1103, the radio frequency circuit 1104, the audio circuit 1105, the input unit 1106, and the power supply 1107. Those skilled in the art will understand that... Figure 5 The air conditioning structure shown does not constitute a limitation on the air conditioning system and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0141] The touch display screen 1103 can be used to display a graphical user interface (GUI) and receive operation commands generated by the user interacting with the GUI. The touch display screen 1103 may include a display panel and a touch panel. The display panel can be used to display information input by the user or information provided to the user, as well as various GUIs of the air conditioner. These GUIs can be composed of graphics, text, icons, video, and any combination thereof. Optionally, the display panel can be configured using a liquid crystal display (LCD), organic light-emitting diode (OLED), or other similar technologies. The touch panel can be used to collect touch operations performed by the user on or near it (such as operations performed by the user using a finger, stylus, or any suitable object or accessory on or near the touch panel), and generate corresponding operation commands, which then execute the corresponding program. Optionally, the touch panel may include a touch detection device and a touch controller. The touch detection device detects the user's touch location and the signal generated by the touch operation, transmitting the signal to the touch controller. The touch controller receives touch information from the touch detection device, converts it into touch point coordinates, and sends it to the processor 1101. It can also receive and execute commands from the processor 1101. The touch panel can cover the display panel. When the touch panel detects a touch operation on or near it, it transmits the information to the processor 1101 to determine the type of touch event. Subsequently, the processor 1101 provides corresponding visual output on the display panel based on the type of touch event. In this embodiment, the touch panel and the display panel can be integrated into the touch display screen 1103 to achieve input and output functions. However, in some embodiments, the touch panel and the touch display screen 1103 can be used as two independent components to achieve input and output functions. That is, the touch display screen 1103 can also be used as part of the input unit 1106 to achieve input functions.

[0143] Audio circuit 1105 can be used to provide an audio interface between the user and the air conditioner via a speaker and a microphone. Audio circuit 1105 can convert received audio data into electrical signals and transmit them to the speaker, where the speaker converts them into sound signals for output. Conversely, the microphone converts collected sound signals into electrical signals, which are then received by audio circuit 1105, converted back into audio data, and then processed by processor 1101 before being transmitted via radio frequency circuit 1104 to, for example, another air conditioner, or output to memory 1102 for further processing. Audio circuit 1105 may also include an earphone jack to provide communication between external headphones and the air conditioner.
