It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0030] Figure 2 FIG. 1 is a flow chart of a method for controlling oxygen concentration of an air conditioner according to an embodiment of the present application. Figure 2 As shown, the method comprises the following steps:

[0031] Step S201, detecting the oxygen concentration in a predetermined space, and when the oxygen concentration is less than a first preset threshold, obtaining a target oxygen concentration, and calculating a difference between the oxygen concentration and the target oxygen concentration to obtain a concentration difference;

[0032] Specifically, the air conditioning system continuously monitors the oxygen concentration level in the room (predetermined space) through the built-in oxygen concentration sensor. The detected oxygen concentration is compared with the set first preset threshold. The first preset threshold is usually a relatively comfortable value, such as 23.5%. A target oxygen concentration value is obtained, which is usually set to 20.9%, which is close to the level of natural oxygen concentration in the atmosphere. Next, the system will calculate the difference (ΔC) between the current indoor oxygen concentration and the target oxygen concentration. This difference will serve as an important basis for adjusting the oxygen production to achieve precise regulation of the indoor oxygen concentration.

[0033] Step S202, detecting the total number of people in the predetermined space, and determining a total oxygen consumption concentration according to the total number of people, wherein the total oxygen consumption concentration represents the total concentration of oxygen consumed by people in the predetermined space;

[0034] Specifically, the system monitors the predetermined space through a millimeter-wave radar sensor, which can capture tiny movements of the human body, such as breathing, heartbeats, or slight body movements, and uses this information to count how many people are in the room. Once the total number of people in the room is detected, the system will calculate the total amount of oxygen consumed by the personnel within a predetermined time (such as every hour). After determining the total oxygen consumption concentration, the system combines it with the indoor oxygen concentration monitored in real time to calculate the actual change value of the indoor oxygen concentration. This change value not only includes the decrease in oxygen concentration due to the breathing of the personnel, but may also take into account other factors, such as the introduction of the fresh air system, the degree of closure of the indoor environment, etc., which affect the oxygen concentration. Finally, based on the difference between the total oxygen consumption concentration and the current indoor oxygen concentration, the air conditioning system can intelligently adjust the output of its oxygen production module to ensure that the indoor oxygen concentration is maintained within the range most suitable for human health. For example, if the calculated total oxygen consumption concentration is significantly different from the current oxygen concentration, indicating that the indoor oxygen concentration has dropped significantly, the system will automatically increase the oxygen production; conversely, if the difference is not large, the system will maintain the existing oxygen production or appropriately reduce it to avoid excessive oxygen production. Through this series of intelligent control logic, the air conditioning system can not only dynamically adjust the oxygen supply according to the number of people in the room to ensure that the indoor environment is always healthy and comfortable, but also effectively reduce energy consumption and avoid potential safety hazards caused by excessive oxygen concentration. This method combines the advanced detection technology of millimeter-wave radar and the precise monitoring of oxygen concentration, reflecting the innovation and intelligent application of smart home devices in improving the quality of living environment.

[0035] Step S203, calculating the sum of the concentration difference and the total oxygen consumption concentration to obtain a total oxygen production concentration, and controlling the air conditioner to produce oxygen according to the total oxygen production concentration.

[0036] Specifically, the concentration difference (ΔC) is added to the total oxygen consumption concentration (assuming it is V', in units of concentration value) to obtain the total oxygen production concentration. This sum combines the immediate shortage and potential consumption of indoor oxygen concentration, provides a quantitative basis for accurately controlling the amount of oxygen produced, and then controls the air conditioner. In the specific implementation process, the above-mentioned first preset threshold can be set to 23.5%, the second preset threshold hereinafter can be set to 19.5%, the target oxygen concentration value can be set to 20.9%, and the third preset threshold hereinafter can be set to 25%.

[0037] Through this embodiment, the oxygen concentration in the predetermined space is detected, and when the oxygen concentration is less than the first preset threshold, the target oxygen concentration is obtained, and the difference between the oxygen concentration and the target oxygen concentration is calculated to obtain the concentration difference; the total number of people in the predetermined space is detected, and the total oxygen consumption concentration is determined according to the total number of people, and the total oxygen consumption concentration represents the total concentration of oxygen consumed by the people in the predetermined space; the sum of the concentration difference and the total oxygen consumption concentration is calculated to obtain the total oxygen production concentration, and the air conditioner is controlled to produce oxygen according to the total oxygen production concentration. Compared with the prior art, when the oxygen concentration reaches the preset concentration, the oxygen supply is stopped, and the oxygen production amount cannot be reasonably adjusted according to the indoor situation, the present application automatically controls the air conditioner to produce oxygen through the oxygen concentration in the predetermined space and the total number of people, and automatically adjusts the indoor oxygen concentration to maintain the indoor oxygen concentration within a comfortable range. Therefore, it can solve the problem that the oxygen production amount cannot be automatically and reasonably adjusted in the prior art, and achieve the purpose of maintaining the indoor oxygen concentration within an ideal comfortable range.

[0038] In the specific implementation process, the above step S201 calculates the difference between the oxygen concentration and the target oxygen concentration to obtain the concentration difference when the oxygen concentration is less than the first preset threshold value, which can be achieved by the following steps: step S2011: when the oxygen concentration is greater than or equal to the second preset threshold value and less than the first preset threshold value, calculate the difference between the oxygen concentration and the target oxygen concentration to obtain the first concentration difference, wherein the target oxygen concentration is greater than the second preset threshold value and less than the first preset threshold value; step S2012: when the oxygen concentration is less than the second preset threshold value, calculate the difference between the oxygen concentration and the target oxygen concentration to obtain the second concentration difference. By calculating the first concentration difference and the second concentration difference in segments, the air conditioner can adjust the oxygen production amount and oxygen production mode more intelligently and accurately, ensuring that the indoor oxygen concentration neither falls into an unhealthy state of hypoxia nor rises excessively to a level that may cause safety problems, thereby providing users with a continuously healthy and comfortable living environment.

[0039] Specifically, when the oxygen concentration is between the second preset threshold value (e.g., 19.5%) and the first preset threshold value (e.g., 23.5%), at this time, the indoor oxygen concentration may be lower than the target oxygen concentration (e.g., 20.9%), which means that although the indoor oxygen environment is not in a hypoxic crisis state, it still needs to be supplemented with an appropriate amount of oxygen to achieve an ideal comfort level. In this case, the first concentration difference is a negative value. The indoor oxygen concentration may also be higher than the target oxygen concentration (e.g., 20.9%). In this case, the first concentration difference is a positive value. When the oxygen concentration is less than the second preset threshold value (e.g., 19.5%), the second concentration difference is a negative value.

[0040] In some optional implementations, the above step S203 calculates the sum of the concentration difference and the total oxygen consumption concentration to obtain the total oxygen production concentration, and controls the air conditioner oxygen production according to the total oxygen production concentration, which can be achieved by the following steps: step S2031: when the oxygen concentration is greater than or equal to the second preset threshold and less than the first preset threshold, calculate the sum of the first concentration difference and the total oxygen consumption concentration to obtain the first total oxygen production concentration, and control the air conditioner oxygen production concentration to be the first total oxygen production concentration; step S2032: when the oxygen concentration is less than the second preset threshold, calculate the sum of the second concentration difference and the total oxygen consumption concentration to obtain the second total oxygen production concentration, and control the air conditioner oxygen production concentration to be the second total oxygen production concentration. The method adopts corresponding control logic in different oxygen concentration intervals to ensure that the air conditioner can adapt to various indoor environmental changes.

[0041] Specifically, when the indoor oxygen concentration is between the second preset threshold and the first preset threshold (for example, 19.5% ≤ oxygen concentration < 23.9%), the first concentration difference (ΔC1) is added to the total oxygen consumption concentration to obtain the first total oxygen production concentration (Q1). When the indoor oxygen concentration is less than the second preset threshold (for example, oxygen concentration < 19.5%), the second concentration difference (ΔC2) is added to the total oxygen consumption concentration to obtain the second total oxygen production concentration (Q2).

[0042] In some optional embodiments, the air conditioner includes a fresh air system and an oxygen production system, the fresh air system is used for air circulation in the predetermined space, and the oxygen production system is used to increase the oxygen concentration in the predetermined space, and the method further includes step S204: when the oxygen concentration is less than a second preset threshold, turning on the fresh air system and the oxygen production system, wherein the second preset threshold is less than the first preset threshold; step S205: when the oxygen concentration is greater than or equal to the second preset threshold and less than the first preset threshold, turning on the oxygen production system. In the above different situations, the method turns on different modes of the air conditioner to adapt to environments with different oxygen concentrations.

[0043] During the specific implementation process, when the indoor oxygen concentration is lower than the second preset threshold, in this case, due to the low indoor oxygen concentration, in order to quickly increase the indoor oxygen concentration to a healthier and more comfortable level, the system will turn on the fresh air system and the oxygen production system at the same time. The operation of the fresh air system helps to introduce outdoor oxygen-rich air, while the oxygen production system directly increases the indoor oxygen content. This dual-system simultaneous operation strategy can quickly improve indoor air quality, ensure that occupants get enough oxygen supply, and avoid the adverse effects of low oxygen environment on health.

[0044] When the indoor oxygen concentration is greater than or equal to the second preset threshold and less than the first preset threshold, the indoor oxygen concentration is already within a relatively comfortable range. In this case, the air conditioning system only turns on the oxygen production system because the indoor oxygen concentration has reached a relatively safe level and there is no need to quickly increase the oxygen content by introducing a large amount of fresh air. The separate operation of the oxygen production system can accurately supplement the required additional oxygen and avoid increased energy consumption or potential safety risks that may be caused by excessive oxygen supply. At the same time, this control method can more effectively manage indoor air quality and maintain it in the best state of human comfort.

[0045] In some optional embodiments, the air conditioner includes a fresh air system and an oxygen production system, the fresh air system is used for air circulation in the predetermined space, and the oxygen production system is used to increase the oxygen concentration in the predetermined space, and the method further includes step S206: when the oxygen concentration is greater than or equal to the first preset threshold and less than a third preset threshold, turning off the oxygen production system and turning on the fresh air system, wherein the third preset threshold is greater than the first preset threshold; step S207: when the oxygen concentration is greater than or equal to the third preset threshold, determining that the concentration is abnormal and turning off the air conditioner. In the above case, the method controls the air conditioner to turn on or off to avoid danger in the predetermined space.

[0046] In the specific implementation process, when the indoor oxygen concentration is greater than or equal to the first preset threshold and less than the third preset threshold, it indicates that the indoor oxygen content is relatively high and close to the level that may have an adverse effect on human health. The third preset threshold (for example, the third preset threshold is 25%) represents a higher safety threshold. When this threshold is exceeded, the indoor oxygen concentration poses a direct threat to safety. The oxygen concentration level between the first preset threshold and the third preset threshold, although higher than the upper limit of the comfort range, has not yet reached a dangerous level. At this time, the control strategy is to turn off the oxygen production system to avoid further increasing the oxygen concentration, and turn on the fresh air system to dilute the oxygen content in the indoor air by introducing outdoor fresh air, thereby reducing the oxygen concentration to a safer and healthier range. When the indoor oxygen concentration is greater than or equal to the third preset threshold, if the indoor oxygen concentration continues to rise and reaches or exceeds the third preset threshold, it indicates that the indoor environment is already in a very dangerous state. High concentrations of oxygen are not only harmful to health, but may also cause fires due to combustion-supporting effects. Therefore, the control system will execute the safety mechanism at this time, determine that the oxygen concentration is abnormal, and immediately shut down the entire air conditioner, including the oxygen production system and the fresh air system.

[0047] In some optional implementations, the above step S202 determines the total oxygen consumption concentration according to the total number of people, which can be achieved by the following steps: step S2021: obtaining individual oxygen consumption concentrations, wherein the individual oxygen consumption concentrations represent the oxygen concentrations consumed by each person per hour; step S2022: calculating the product of the individual oxygen consumption concentrations and the total number of people to obtain the total oxygen consumption concentration. The method calculates the total oxygen consumption concentration through the above steps, and accurately calculating the oxygen consumption of indoor personnel is one of the key steps to achieve dynamic balance and optimization.

[0048] Specifically, the oxygen consumption per adult per minute is about 0.35 liters, so the total oxygen consumption per hour for n people is: 0.35*60*n=21n (liters). The total oxygen consumption can be further converted into the total oxygen consumption concentration.

[0049] In some optional embodiments, the air conditioner further includes a millimeter wave radar, and the above step S202 detects the total number of people in the predetermined space, which can also be achieved by the following steps: step S2023: transmitting electromagnetic waves through the millimeter wave radar in the predetermined space, and receiving echo signals of the electromagnetic waves; step S2024: preprocessing the echo signals, and extracting features from the preprocessed echo signals to obtain human features, and identifying people on the echo signals according to the human features to obtain the total number of people in the predetermined space. The method accurately identifies the total number of people in the room through the millimeter wave radar to ensure accurate adjustment of the air conditioner.

[0050] In the specific implementation process, infrared sensors can also be used to detect the number of people. Multi-point measurement is required, that is, sensors are arranged in multiple areas, so as to detect the number of people from multiple angles and multiple positions; infrared sensors can be combined with other sensors or technologies to achieve accurate counting, such as ultrasonic sensors, cameras or image processing technologies, etc. More accurately, millimeter-wave radars are used, which can effectively and accurately count by emitting, reflecting, and receiving high-frequency electromagnetic waves, combined with advanced signal processing methods and machine learning algorithms. In static conditions, millimeter-wave radars can identify the presence of people by detecting tiny movements of the human body; in dynamic conditions, millimeter-wave radars can detect the movement of the human body to identify people. Clustering algorithms are used to count the number of people.

[0051] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for controlling the oxygen concentration of the air conditioner of the present application will be described in detail below in combination with specific embodiments.

[0070] Specifically, the air conditioning system continuously monitors the oxygen concentration level in the room (predetermined space) through the built-in oxygen concentration sensor. The detected oxygen concentration is compared with the set first preset threshold. The first preset threshold is usually a relatively comfortable value, such as 23.5%. A target oxygen concentration value is obtained, which is usually set to 20.9%, which is close to the level of natural oxygen concentration in the atmosphere. Next, the system will calculate the difference (ΔC) between the current indoor oxygen concentration and the target oxygen concentration. This difference will serve as an important basis for adjusting the oxygen production to achieve precise regulation of the indoor oxygen concentration.

[0071] A determination unit 20, configured to detect a total number of people in the predetermined space, and determine a total oxygen consumption concentration according to the total number of people, wherein the total oxygen consumption concentration represents a total concentration of oxygen consumed by people in the predetermined space;

[0072] Specifically, the system monitors the predetermined space through a millimeter-wave radar sensor, which can capture tiny movements of the human body, such as breathing, heartbeats, or slight body movements, and uses this information to count how many people are in the room. Once the total number of people in the room is detected, the system will calculate the total amount of oxygen consumed by the personnel within a predetermined time (such as every hour). After determining the total oxygen consumption concentration, the system combines it with the indoor oxygen concentration monitored in real time to calculate the actual change value of the indoor oxygen concentration. This change value not only includes the decrease in oxygen concentration due to the breathing of the personnel, but may also take into account other factors, such as the introduction of the fresh air system, the degree of closure of the indoor environment, etc., which affect the oxygen concentration. Finally, based on the difference between the total oxygen consumption concentration and the current indoor oxygen concentration, the air conditioning system can intelligently adjust the output of its oxygen production module to ensure that the indoor oxygen concentration is maintained within the range most suitable for human health. For example, if the calculated total oxygen consumption concentration is significantly different from the current oxygen concentration, indicating that the indoor oxygen concentration has dropped significantly, the system will automatically increase the oxygen production; conversely, if the difference is not large, the system will maintain the existing oxygen production or appropriately reduce it to avoid excessive oxygen production. Through this series of intelligent control logic, the air conditioning system can not only dynamically adjust the oxygen supply according to the number of people in the room to ensure that the indoor environment is always healthy and comfortable, but also effectively reduce energy consumption and avoid potential safety hazards caused by excessive oxygen concentration. This device combines the advanced detection technology of millimeter-wave radar and the precise monitoring of oxygen concentration, reflecting the innovation and intelligent application of smart home devices in improving the quality of living environment.

[0073] The control unit 30 is used to calculate the sum of the concentration difference and the total oxygen consumption concentration to obtain a total oxygen production concentration, and control the air conditioner to produce oxygen according to the total oxygen production concentration.

[0074] Specifically, the concentration difference (ΔC) is added to the total oxygen consumption concentration (assuming it is V', in units of concentration value) to obtain the total oxygen production concentration. This sum combines the immediate shortage and potential consumption of indoor oxygen concentration, provides a quantitative basis for accurately controlling the amount of oxygen produced, and then controls the air conditioner. In the specific implementation process, the above-mentioned first preset threshold can be set to 23.5%, the second preset threshold hereinafter can be set to 19.5%, the target oxygen concentration value can be set to 20.9%, and the third preset threshold hereinafter can be set to 25%.

[0075] Through this embodiment, the oxygen concentration in the predetermined space is detected, and when the oxygen concentration is less than the first preset threshold, the target oxygen concentration is obtained, and the difference between the oxygen concentration and the target oxygen concentration is calculated to obtain the concentration difference; the total number of people in the predetermined space is detected, and the total oxygen consumption concentration is determined according to the total number of people, and the total oxygen consumption concentration represents the total concentration of oxygen consumed by the people in the predetermined space; the sum of the concentration difference and the total oxygen consumption concentration is calculated to obtain the total oxygen production concentration, and the air conditioner is controlled to produce oxygen according to the total oxygen production concentration. Compared with the prior art, when the oxygen concentration reaches the preset concentration, the oxygen supply is stopped, and the oxygen production amount cannot be reasonably adjusted according to the indoor situation, the present application automatically controls the air conditioner to produce oxygen through the oxygen concentration in the predetermined space and the total number of people, and automatically adjusts the indoor oxygen concentration to maintain the indoor oxygen concentration within a comfortable range. Therefore, it can solve the problem that the oxygen production amount cannot be automatically and reasonably adjusted in the prior art, and achieve the purpose of maintaining the indoor oxygen concentration within an ideal comfortable range.

[0076] In the specific implementation process, the calculation unit includes a first calculation module and a second calculation module. The first calculation module is used to calculate the difference between the oxygen concentration and the target oxygen concentration when the oxygen concentration is greater than or equal to the second preset threshold and less than the first preset threshold, so as to obtain a first concentration difference, wherein the target oxygen concentration is greater than the second preset threshold and less than the first preset threshold; the second calculation module is used to calculate the difference between the oxygen concentration and the target oxygen concentration when the oxygen concentration is less than the second preset threshold, so as to obtain a second concentration difference. By calculating the first concentration difference and the second concentration difference in sections, the air conditioner can more intelligently and accurately adjust the oxygen production amount and oxygen production mode, ensuring that the indoor oxygen concentration neither falls into an unhealthy state of hypoxia nor rises excessively to a level that may cause safety problems, thereby providing users with a continuously healthy and comfortable living environment.

[0077] Specifically, when the oxygen concentration is between the second preset threshold value (e.g., 19.5%) and the first preset threshold value (e.g., 23.5%), at this time, the indoor oxygen concentration may be lower than the target oxygen concentration (e.g., 20.9%), which means that although the indoor oxygen environment is not in a hypoxic crisis state, it still needs to be supplemented with an appropriate amount of oxygen to achieve an ideal comfort level. In this case, the first concentration difference is a negative value. The indoor oxygen concentration may also be higher than the target oxygen concentration (e.g., 20.9%). In this case, the first concentration difference is a positive value. When the oxygen concentration is less than the second preset threshold value (e.g., 19.5%), the second concentration difference is a negative value.

[0078] In some optional embodiments, the control unit includes a first control module and a second control module. The first control module is used to calculate the sum of the first concentration difference and the total oxygen consumption concentration when the oxygen concentration is greater than or equal to the second preset threshold and less than the first preset threshold, obtain a first total oxygen production concentration, and control the oxygen production concentration of the air conditioner to be the first total oxygen production concentration; the second control module is used to calculate the sum of the second concentration difference and the total oxygen consumption concentration when the oxygen concentration is less than the second preset threshold, obtain a second total oxygen production concentration, and control the oxygen production concentration of the air conditioner to be the second total oxygen production concentration. The device adopts corresponding control logic in different oxygen concentration ranges to ensure that the air conditioner can adapt to various indoor environmental changes.

[0079] Specifically, when the indoor oxygen concentration is between the second preset threshold and the first preset threshold (for example, 19.5% ≤ oxygen concentration < 23.9%), the first concentration difference (ΔC1) is added to the total oxygen consumption concentration to obtain the first total oxygen production concentration (Q1). When the indoor oxygen concentration is less than the second preset threshold (for example, oxygen concentration < 19.5%), the second concentration difference (ΔC2) is added to the total oxygen consumption concentration to obtain the second total oxygen production concentration (Q2).

[0080] In some optional embodiments, the air conditioner includes a fresh air system and an oxygen production system, the fresh air system is used for air circulation in the predetermined space, and the oxygen production system is used to increase the oxygen concentration in the predetermined space. The device also includes a first opening unit and a second opening unit, the first opening unit is used to open the fresh air system and the oxygen production system when the oxygen concentration is less than a second preset threshold, wherein the second preset threshold is less than the first preset threshold; the second opening unit is used to open the oxygen production system when the oxygen concentration is greater than or equal to the second preset threshold and less than the first preset threshold. The device turns on different modes of the air conditioner in the above different situations to adapt to environments with different oxygen concentrations.

[0081] During the specific implementation process, when the indoor oxygen concentration is lower than the second preset threshold, in this case, due to the low indoor oxygen concentration, in order to quickly increase the indoor oxygen concentration to a healthier and more comfortable level, the system will turn on the fresh air system and the oxygen production system at the same time. The operation of the fresh air system helps to introduce outdoor oxygen-rich air, while the oxygen production system directly increases the indoor oxygen content. This dual-system simultaneous operation strategy can quickly improve indoor air quality, ensure that occupants get enough oxygen supply, and avoid the adverse effects of low oxygen environment on health.

[0082] When the indoor oxygen concentration is greater than or equal to the second preset threshold and less than the first preset threshold, the indoor oxygen concentration is already within a relatively comfortable range. In this case, the air conditioning system only turns on the oxygen production system because the indoor oxygen concentration has reached a relatively safe level and there is no need to quickly increase the oxygen content by introducing a large amount of fresh air. The separate operation of the oxygen production system can accurately supplement the required additional oxygen and avoid increased energy consumption or potential safety risks that may be caused by excessive oxygen supply. At the same time, this control method can more effectively manage indoor air quality and maintain it in the best state of human comfort.

[0083] In some optional embodiments, the air conditioner includes a fresh air system and an oxygen production system, the fresh air system is used for air circulation in the predetermined space, and the oxygen production system is used to increase the oxygen concentration in the predetermined space. The device also includes a third opening unit and a closing unit, the third opening unit is used to close the oxygen production system and open the fresh air system when the oxygen concentration is greater than or equal to the first preset threshold and less than a third preset threshold, wherein the third preset threshold is greater than the first preset threshold; the closing unit is used to determine that the concentration is abnormal and close the air conditioner when the oxygen concentration is greater than or equal to the third preset threshold. In the above case, the device controls the air conditioner to be turned on or off to avoid danger in the predetermined space.

[0084] In the specific implementation process, when the indoor oxygen concentration is greater than or equal to the first preset threshold and less than the third preset threshold, it indicates that the indoor oxygen content is relatively high and close to the level that may have an adverse effect on human health. The third preset threshold (for example, the third preset threshold is 25%) represents a higher safety threshold. When this threshold is exceeded, the indoor oxygen concentration poses a direct threat to safety. The oxygen concentration level between the first preset threshold and the third preset threshold, although higher than the upper limit of the comfort range, has not yet reached a dangerous level. At this time, the control strategy is to turn off the oxygen production system to avoid further increasing the oxygen concentration, and turn on the fresh air system to dilute the oxygen content in the indoor air by introducing outdoor fresh air, thereby reducing the oxygen concentration to a safer and healthier range. When the indoor oxygen concentration is greater than or equal to the third preset threshold, if the indoor oxygen concentration continues to rise and reaches or exceeds the third preset threshold, it indicates that the indoor environment is already in a very dangerous state. High concentrations of oxygen are not only harmful to health, but may also cause fires due to combustion-supporting effects. Therefore, the control system will execute the safety mechanism at this time, determine that the oxygen concentration is abnormal, and immediately shut down the entire air conditioner, including the oxygen production system and the fresh air system.

[0085] In some optional embodiments, the determination unit includes an acquisition module and a third calculation module, the acquisition module is used to acquire the individual oxygen consumption concentration, wherein the individual oxygen consumption concentration represents the oxygen concentration consumed by each person per hour; the third calculation module is used to calculate the product of the individual oxygen consumption concentration and the total number of people to obtain the total oxygen consumption concentration. The device calculates the total oxygen consumption concentration through the above steps, and accurately calculating the oxygen consumption of indoor personnel is one of the key steps to achieve dynamic balance and optimization.

[0086] Specifically, the oxygen consumption per adult per minute is about 0.35 liters, so the total oxygen consumption per hour for n people is: 0.35*60*n=21n (liters). The total oxygen consumption can be further converted into the total oxygen consumption concentration.

[0087] In some optional embodiments, the air conditioner further includes a millimeter wave radar, and the above-mentioned determination unit includes a receiving module and an identification module, the receiving module is used to transmit electromagnetic waves through the millimeter wave radar in the predetermined space and receive the echo signal of the electromagnetic wave; the identification module is used to pre-process the echo signal, and extract features from the pre-processed echo signal to obtain human features, and identify people on the echo signal according to the human features to obtain the total number of people in the predetermined space. The device accurately identifies the total number of people in the room through the millimeter wave radar to ensure accurate adjustment of the air conditioner.

[0088] In the specific implementation process, infrared sensors can also be used to detect the number of people. Multi-point measurement is required, that is, sensors are arranged in multiple areas, so as to detect the number of people from multiple angles and multiple positions; infrared sensors can be combined with other sensors or technologies to achieve accurate counting, such as ultrasonic sensors, cameras or image processing technologies, etc. More accurately, millimeter-wave radars are used, which can effectively and accurately count by emitting, reflecting, and receiving high-frequency electromagnetic waves, combined with advanced signal processing devices and machine learning algorithms. In static conditions, millimeter-wave radars can identify the presence of people by detecting tiny movements of the human body; in dynamic conditions, millimeter-wave radars can detect the movement of the human body to identify people. Clustering algorithms are used to count the number of people.

[0089] The control device for oxygen concentration of the air conditioner includes a processor and a memory. The calculation unit, the determination unit and the control unit are stored in the memory as program units, and the processor executes the program units stored in the memory to realize the corresponding functions. The modules are all located in the same processor; or, the modules are located in different processors in any combination.

[0090] The processor includes a kernel, which calls the corresponding program unit from the memory. One or more kernels can be set, and the indoor oxygen concentration can be maintained within the ideal comfortable range by adjusting the kernel parameters.

[0091] The memory may include non-permanent memory in a computer-readable medium, random access memory (RAM) and / or non-volatile memory, such as read-only memory (ROM) or flash RAM, and the memory includes at least one memory chip.

[0092] An embodiment of the present invention provides a computer-readable storage medium, wherein the computer-readable storage medium includes a stored program, wherein when the program is executed, the device where the computer-readable storage medium is located is controlled to execute the method for controlling the oxygen concentration of the air conditioner.

[0093] Specifically, the method for controlling the oxygen concentration of the air conditioner includes:

[0094] Step S201, detecting the oxygen concentration in a predetermined space, and when the oxygen concentration is less than a first preset threshold, obtaining a target oxygen concentration, and calculating a difference between the oxygen concentration and the target oxygen concentration to obtain a concentration difference;

[0095] Specifically, the air conditioning system continuously monitors the oxygen concentration level in the room (predetermined space) through the built-in oxygen concentration sensor. The detected oxygen concentration is compared with the set first preset threshold. The first preset threshold is usually a relatively comfortable value, such as 23.5%. A target oxygen concentration value is obtained, which is usually set to 20.9%, which is close to the level of natural oxygen concentration in the atmosphere. Next, the system will calculate the difference (ΔC) between the current indoor oxygen concentration and the target oxygen concentration. This difference will serve as an important basis for adjusting the oxygen production to achieve precise regulation of the indoor oxygen concentration.

[0096] Step S202, detecting the total number of people in the predetermined space, and determining a total oxygen consumption concentration according to the total number of people, wherein the total oxygen consumption concentration represents the total concentration of oxygen consumed by people in the predetermined space;

Once the total number of people in the room is detected, the system will calculate the total amount of oxygen consumed by the personnel within a predetermined time (such as every hour). After determining the total oxygen consumption concentration, the system combines it with the indoor oxygen concentration monitored in real time to calculate the actual change value of the indoor oxygen concentration. This change value not only includes the decrease in oxygen concentration due to the breathing of the personnel, but may also take into account other factors, such as the introduction of the fresh air system, the degree of closure of the indoor environment, etc., which affect the oxygen concentration. Finally, based on the difference between the total oxygen consumption concentration and the current indoor oxygen concentration, the air conditioning system can intelligently adjust the output of its oxygen production module to ensure that the indoor oxygen concentration is maintained within the range most suitable for human health. For example, if the calculated total oxygen consumption concentration is significantly different from the current oxygen concentration, indicating that the indoor oxygen concentration has dropped significantly, the system will automatically increase the oxygen production; conversely, if the difference is not large, the system will maintain the existing oxygen production or appropriately reduce it to avoid excessive oxygen production.

[0098] Step S203, calculating the sum of the concentration difference and the total oxygen consumption concentration to obtain a total oxygen production concentration, and controlling the air conditioner to produce oxygen according to the total oxygen production concentration.

[0099] Specifically, the concentration difference (ΔC) is added to the total oxygen consumption concentration (assuming it is V', in units of concentration value) to obtain the total oxygen production concentration. This sum combines the immediate shortage and potential consumption of indoor oxygen concentration, provides a quantitative basis for accurately controlling the amount of oxygen produced, and then controls the air conditioner. In the specific implementation process, the above-mentioned first preset threshold can be set to 23.5%, the second preset threshold hereinafter can be set to 19.5%, the target oxygen concentration value can be set to 20.9%, and the third preset threshold hereinafter can be set to 25%.
