For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0037] The present invention provides a control method for oxygen production equipment, which may be an oxygen production equipment on an air conditioner.

[0038] Figure 1 1 is a schematic diagram of an embodiment of a method for controlling an oxygen production device provided by the present invention.

[0039] like Figure 1 As shown, according to one embodiment of the present invention, the control method at least includes step S110, step S120, step S130 and step S140.

[0040] Step S110 , collecting user attributes and physiological parameters of the current user in the space and the current environmental parameters of the space.

[0041] Physiological parameters may specifically include at least one of heart rate, pulse, and metabolic rate. User attributes may specifically include at least one of gender, age, and body type. Body type may be, for example, calculated using a body mass index (BMI) based on height and weight according to a preset formula. Different environments may specifically include at least one of seasonal environments, climatic environments, and geographical environments. Different environments may be represented by environmental parameters. Environmental parameters may specifically include oxygen concentration, and at least one of air temperature, air humidity, air flow rate, and pollutant concentration.

[0042] Step S120 , based on the collected user attributes, physiological parameters and environmental parameters, and according to a pre-established oxygen concentration comfort model, determines the oxygen concentration comfort value of the current user.

[0043] The oxygen concentration comfort model is a pre-established oxygen concentration comfort model for users with different user attributes under different environmental parameters. The collected user attributes, physiological parameters, and environmental parameters are input into the oxygen concentration comfort model to output the oxygen concentration comfort value of the current user.

[0044] Figure 2 A flowchart diagram showing a specific embodiment of the steps of establishing an oxygen concentration comfort model for users with different user attributes under different environmental parameters according to the present invention.

[0045] like Figure 2 As shown, the steps of establishing the oxygen concentration comfort model may specifically include steps S1 to S2:

[0046] Step S1 : collecting physiological parameters and oxygen concentration comfort feedback information of users with different user attributes under different environmental parameters.

[0047] In one specific embodiment, an oxygen concentration comfort experiment is conducted to collect physiological parameters and oxygen concentration comfort feedback information from users with different user attributes under different environmental parameters. For example, users with different user attributes (gender, age, and body type) are selected as subjects, and different test environments (seasonal, climatic, geographical, etc.) are used. The oxygen concentration comfort experiment collects physiological parameters and oxygen concentration comfort feedback information from users with different user attributes under different environmental parameters.

[0048] Specifically, through the oxygen concentration comfort experiment, the physiological parameters of the subjects, the environmental parameters in the experiment, and the oxygen concentration comfort feedback of the subjects are collected to establish an individual difference oxygen concentration comfort sample library. During the oxygen concentration comfort experiment, the physiological parameters, environmental parameters and oxygen concentration comfort feedback information of the subjects are collected at preset intervals. The oxygen concentration comfort feedback information may specifically include air quality somatosensory feedback information and breathing comfort feedback information. During the oxygen concentration comfort experiment, the oxygen concentration in the experimental environment can be changed at preset intervals to obtain the oxygen concentration comfort feedback information of the subjects under different oxygen concentrations.

[0049] In a specific embodiment, oxygen concentration comfort feedback information of users with different user attributes under different environmental parameters and different oxygen concentrations can be collected through a questionnaire. Figure 3 An example of an oxygen concentration comfort experiment questionnaire is shown in FIG. Figure 3As shown, the main content filled in the questionnaire includes the subject's personal information (i.e. user attribute information, such as gender, age, height, weight) and the current subject's oxygen concentration comfort feedback information, including air quality somatosensory feedback, breathing comfort feedback, etc. For example, air quality somatosensory feedback can be set to 7 levels of indicators, representing the subject's somatosensory indoor air quality, with values ​​of -3, -2, -1, 0, 1, 2, and 3, corresponding to very bad, very bad, bad, moderate, good, very good, and very good states, respectively. Breathing comfort feedback can be set to 4 levels of indicators, representing the subject's comfort level when breathing, with values ​​of 0, 1, 2, and 3, corresponding to very uncomfortable, uncomfortable, comfortable, and very comfortable states, respectively.

[0050] Step S2: establishing an oxygen concentration comfort model based on the collected physiological parameters and oxygen concentration comfort feedback information of the users with different user attributes under different environmental parameters.

[0051] Specifically, user attributes, physiological parameters and environmental parameters are used as input parameters, and oxygen concentration comfort feedback information is used as output parameters to perform model training, and obtain oxygen concentration comfort models for users with different user attributes under different environmental parameters.

[0052] Through experimental design and questionnaires, a large amount of oxygen concentration comfort data was obtained. After statistical analysis of the experimental data, a machine learning algorithm was used to train the data and establish a model for individual oxygen concentration comfort. The collected user attributes, physiological parameters, and environmental parameters were input into the oxygen concentration comfort model to output the current user's oxygen concentration comfort value.

[0053] Step S130: determining a current target oxygen concentration according to the determined oxygen concentration comfort value of the current user.

[0054] In a specific embodiment, determining the current target oxygen concentration based on the determined oxygen concentration comfort value of the current user includes the following situations:

[0055] 1) If the current user's oxygen concentration comfort value is less than a first threshold, the current target oxygen concentration is determined to be the upper limit of the oxygen concentration range that can be set by the oxygen generator.

[0056] That is, the target oxygen concentration is Y, and the oxygen generator can set the upper limit of the oxygen concentration range to Ymax, then Y = Ymax. For example, the first threshold is -2.5, that is, when the oxygen concentration comfort value S < -2.5, the target oxygen concentration is Y = Ymax.

[0057] 2) If the current user's oxygen concentration comfort value is greater than or equal to the first threshold and less than the second threshold, determining a current target oxygen concentration based on the last determined target oxygen concentration, the set target oxygen concentration change rate corresponding to the current user's oxygen concentration comfort value, and the current user's oxygen concentration comfort value. The last determined target oxygen concentration is the target oxygen concentration last determined based on the user's oxygen concentration comfort value, i.e., the target oxygen concentration last determined when the steps of the method of the present invention were performed.

[0058] The current target oxygen concentration Y is equal to the target oxygen concentration Y0 determined last time plus the product of the set target oxygen concentration change rate KL and the difference between the current user's oxygen concentration comfort value and the second threshold value, that is, Y=Y0+K L ×(S-S2). When the current user's oxygen concentration comfort value is in different oxygen concentration comfort value intervals, different target oxygen concentration change rates are set. When the current user's oxygen concentration comfort value is greater than or equal to the first threshold and less than the second threshold, it is in the poor air quality sensation interval, and the target oxygen concentration change rate K is set. L For example, the first threshold S1 is -2.5, the second threshold S2 is -0.5, and the oxygen concentration comfort value range is -2.5≤S<-0.5, which is in the poor air quality range. The corresponding target oxygen concentration change rate K is set. L , then Y=Y0+K L ×(S+0.5).

[0059] When the current user's oxygen concentration comfort value is greater than or equal to the first threshold and less than the second threshold, the set target oxygen concentration change rate is equal to the slope of a coordinate system with the oxygen concentration comfort as the horizontal axis and the target oxygen concentration as the vertical axis, from a point determined by the upper limit value Ymax of the settable oxygen concentration range of the oxygen concentrator and the minimum value of the oxygen concentration comfort in this interval to a point determined by the last determined target oxygen concentration Y0 and the maximum value of the oxygen concentration comfort in this interval.

[0060] Figure 4 A schematic diagram of the coordinate system of the target oxygen concentration and the current user's oxygen concentration comfort value is shown. Figure 4 As shown, the horizontal axis represents the oxygen concentration comfort level S, and the vertical axis represents the target oxygen concentration Y. For example, when the oxygen concentration comfort level is in the range of -2.5 ≤ S < -0.5, the target oxygen concentration change rate is set as the slope from the point defined by the upper limit of the oxygen concentration range settable by the oxygen generator, Ymax, and the minimum oxygen concentration comfort level in that range, -2.5, to the point defined by the last determined target oxygen concentration, Y0, and the maximum oxygen concentration comfort level in that range, -0.5. In other words, this is the slope of the line whose horizontal axis is in the range of -2.5 ≤ S < -0.5.

[0061] 3) If the current user's oxygen concentration comfort value is greater than or equal to the second threshold and less than the third threshold, the current target oxygen concentration is determined to be equal to the previously determined target oxygen concentration. That is, if the oxygen concentration comfort value is within this oxygen concentration comfort value range, there is no need to adjust the target oxygen concentration; the previously determined target oxygen concentration can be maintained.

[0062] That is, if the target oxygen concentration is Y and the last determined target oxygen concentration is Y0, then Y = Y0. For example, if the second threshold is -0.5 and the third threshold is 0.5, when -0.5 ≤ S < 0.5, there is no need to adjust the target oxygen concentration; the last determined target oxygen concentration can be maintained.

[0063] 4) If the current user's oxygen concentration comfort value is greater than or equal to the third threshold and less than the fourth threshold, the current target oxygen concentration is determined based on the last determined target oxygen concentration, the set target oxygen concentration change rate corresponding to the current user's oxygen concentration comfort value, and the current user's oxygen concentration comfort value.

[0064] The current target oxygen concentration Y is equal to the target oxygen concentration Y0 determined last time plus the product of the set target oxygen concentration change rate KH and the difference between the current user's oxygen concentration comfort value and the third threshold value, that is, Y=Y0+K H ×(S-S3). When the current user's oxygen concentration comfort value is in different oxygen concentration comfort value intervals, different target oxygen concentration change rates are set. When the current user's oxygen concentration comfort value is greater than or equal to the third threshold and less than the fourth threshold, it is in the air quality feeling good interval, and the corresponding target oxygen concentration change rate K is set. H For example, the third threshold S3 is 0.5, the fourth threshold S4 is 2.5, and the oxygen concentration comfort value range is 0.5≤S<2.5, which is in the good air quality range. The corresponding target oxygen concentration change rate K is set. H , then Y=Y0+K H ×(S-0.5).

[0065] The current user's oxygen concentration comfort value is greater than or equal to the third threshold and less than the fourth threshold. The set target oxygen concentration change rate is equal to the slope of a coordinate system with oxygen concentration comfort as the horizontal axis and target oxygen concentration as the vertical axis, from a point determined by a lower limit value Ymin of the settable oxygen concentration range of the oxygen generator and the maximum value of the oxygen concentration comfort in the interval to a point determined by a previously determined target oxygen concentration Y0 and the minimum value of the oxygen concentration comfort in the interval.

[0066] Figure 4 A schematic diagram of the coordinate system of the target oxygen concentration and the current user's oxygen concentration comfort value is shown. Figure 4As shown, the horizontal axis represents the oxygen concentration comfort level S, and the vertical axis represents the target oxygen concentration Y. For example, when the oxygen concentration comfort level is in the range of 0.5 ≤ S < 2.5, the target oxygen concentration change rate is set to the slope from the point defined by the lower limit of the oxygen concentration range (Ymin) of the oxygen generator and the maximum oxygen concentration comfort level (2.5) in that range to the point defined by the previously determined target oxygen concentration (Y0) and the minimum oxygen concentration comfort level (0.5) in that range. In other words, this is the slope of the line whose horizontal axis is in the range of 0.5 ≤ S < 2.5.

[0067] 5) If the current user's oxygen concentration comfort value is greater than or equal to the fourth threshold, the current target oxygen concentration is determined to be the lower limit of the oxygen concentration range that can be set by the oxygen generator.

[0068] That is, the target oxygen concentration is Y, and the oxygen production equipment can set the lower limit of the oxygen concentration range to Ymin, that is, Y = Ymin. For example, the fourth threshold is 2.5, when S ≥ 2.5, the target oxygen concentration Y = Ymin.

[0069] According to the above embodiment, the current target oxygen concentration is determined according to whether the current user's oxygen concentration comfort value is in different comfort intervals, so that the target oxygen concentration suitable for the current user can be determined more accurately.

[0070] In a specific example, the first threshold is -2.5, the second threshold is -0.5, the third threshold is 0.5, and the fourth threshold is 2.5. The target oxygen concentration can be determined using the following formula:

[0071]

[0072] Among them, Y is the target oxygen concentration, Y0 is the oxygen concentration setting value obtained by the last calculation, Ymax is the upper limit of the oxygen concentration range that can be set by the air-conditioning oxygen generator, Ymin is the lower limit of the oxygen concentration range that can be set by the air-conditioning oxygen generator, and S is the oxygen concentration comfort value of the current user determined by the oxygen concentration comfort model (the higher S is, the more comfortable the current oxygen concentration is for the current user). When S is 0, it is considered that the current oxygen concentration is already in a relatively comfortable state for the current user).

[0073] K L Represents the rate of change of the set target oxygen concentration corresponding to the interval of poor air quality sensation (oxygen concentration comfort value -2.5≤S<-0.5), which is equal to the slope from the point determined by Ymax and the minimum value of oxygen concentration comfort in this interval (-2.5) to the point determined by Y0 and the maximum value of oxygen concentration comfort in this interval (-0.5) in the coordinate system with oxygen concentration comfort as the horizontal axis and target oxygen concentration as the vertical axis. K HThis represents the rate of change of the target oxygen concentration for the range with good air quality sensation (the range where oxygen concentration comfort value is 0.5 ≤ S < 2.5). It is equal to the slope from the point determined by Ymin and the maximum oxygen concentration comfort value (2.5) in the coordinate system with oxygen concentration comfort value as the horizontal axis and target oxygen concentration as the vertical axis to the point determined by Y0 and the minimum oxygen concentration comfort value (0.5) in the range. It should be noted that when S is in the range of -0.5 to 0.5, there is no need to adjust the target oxygen concentration; the last target oxygen concentration can be maintained.

[0074] Step S140: Controlling the operation of the oxygen production equipment according to the determined current target oxygen concentration.

[0075] Specifically, the target operating time and target operating power required for the oxygen production equipment to achieve the current target oxygen concentration in the space are determined; and the oxygen production equipment is controlled to operate according to the determined target operating time and target operating power.

[0076] Among them, different target oxygen concentrations correspond to different target operating times and target operating powers. The target operating time and target operating power required by the oxygen production equipment corresponding to the current target oxygen concentration can be determined based on the pre-set correspondence between the target oxygen concentration, the target operating time, and the target operating power. For example, a database of operating time and operating power can be pre-constructed, in which target operating times and target operating powers corresponding to multiple target oxygen concentrations are pre-stored. The target oxygen concentration is matched with the multiple target oxygen concentrations in the database, and the time and power corresponding to the successfully matched target oxygen concentration are determined as the target operating time and target operating power. The oxygen production equipment is controlled to operate at the target operating time and target operating power, so that the oxygen concentration in the space can be adjusted to the target oxygen concentration as soon as possible.

[0077] Figure 5 1 is a schematic diagram of another embodiment of the control method for the oxygen production equipment provided by the present invention.

[0078] like Figure 5 As shown, according to one embodiment of the present invention, the control method further includes step S150 and step S160.

[0079] Step S150: After controlling the oxygen production equipment to operate for a preset time according to the determined current target oxygen concentration, the oxygen concentration of the space is obtained.

[0080] Step S160, determining whether the oxygen concentration in the space is less than the current target oxygen concentration, if so, controlling the oxygen production equipment to continue operating, if not, controlling the oxygen production equipment to shut down.

[0081] Specifically, after controlling the oxygen production equipment to run for a preset time according to the target oxygen concentration, the oxygen concentration of the space can be detected by an oxygen detection module (such as an oxygen concentration sensor). If the oxygen concentration in the space is less than the target oxygen concentration, it means that the running time of the oxygen production equipment is not long enough and is not enough to meet the needs of the user. At this time, the oxygen production equipment is controlled to continue running. The indoor oxygen concentration is increased by the operation of the oxygen production equipment to reach the target oxygen concentration. After the oxygen production equipment is controlled to continue running, the indoor oxygen concentration is continued to be monitored in order to better adjust the indoor air quality. If the oxygen concentration in the space is greater than or equal to the target oxygen concentration, it means that the indoor oxygen concentration is sufficient and can meet the needs of the user. At this time, the oxygen production equipment is controlled to stop running.

[0082] According to the above-mentioned embodiment, whether the oxygen production equipment should continue to operate is determined based on the oxygen concentration in the space, which can save energy.

[0097] The present invention provides a control device for oxygen production equipment, which may be specifically an oxygen production equipment on an air conditioner.

[0098] Figure 8 FIG. 1 is a structural block diagram of an embodiment of the control device of the oxygen production equipment provided by the present invention. Figure 8 As shown, the control device 100 includes: a collection unit 110 , a first determination unit 120 , a second determination unit 130 and a control unit 140 .

[0099] The collecting unit 110 is used to collect user attributes and physiological parameters of the current user in the space and the current environmental parameters of the space.

[0100] Physiological parameters may specifically include at least one of heart rate, pulse, and metabolic rate. User attributes may specifically include at least one of gender, age, and body type. Body type may be, for example, calculated using a body mass index (BMI) based on height and weight according to a preset formula. Different environments may specifically include at least one of seasonal environments, climatic environments, and geographical environments. Different environments may be represented by environmental parameters. Environmental parameters may specifically include oxygen concentration, and at least one of air temperature, air humidity, air flow rate, and pollutant concentration.

[0101] The first determining unit 120 is configured to determine the oxygen concentration comfort value of the current user based on the user attributes, physiological parameters, and environmental parameters collected by the collecting unit 110 and according to a pre-established oxygen concentration comfort model.

[0102] The oxygen concentration comfort model is a pre-established oxygen concentration comfort model for users with different user attributes under different environmental parameters. The collected user attributes, physiological parameters, and environmental parameters are input into the oxygen concentration comfort model to output the oxygen concentration comfort value for the current user.

[0103] Accordingly, the apparatus 100 further includes: an establishing unit (not shown) for establishing an oxygen concentration comfort model for users with different user attributes under different environmental parameters. Figure 2 A flowchart diagram showing a specific embodiment of the steps of establishing an oxygen concentration comfort model for users with different user attributes under different environmental parameters according to the present invention.

[0104] like Figure 2 The steps of establishing the oxygen concentration comfort model may specifically include steps S1 and S2:

[0105] Step S1 : collecting physiological parameters and oxygen concentration comfort feedback information of users with different user attributes under different environmental parameters.

[0106] In one specific embodiment, an oxygen concentration comfort experiment is conducted to collect physiological parameters and oxygen concentration comfort feedback information from users with different user attributes under different environmental parameters. For example, users with different user attributes (gender, age, and body type) are selected as subjects, and different test environments (seasonal, climatic, geographical, etc.) are used. The oxygen concentration comfort experiment collects physiological parameters and oxygen concentration comfort feedback information from users with different user attributes under different environmental parameters.

[0107] Specifically, through the oxygen concentration comfort experiment, the physiological parameters of the subjects, the environmental parameters in the experiment, and the oxygen concentration comfort feedback of the subjects are collected to establish an individual difference oxygen concentration comfort sample library. During the oxygen concentration comfort experiment, the physiological parameters, environmental parameters and oxygen concentration comfort feedback information of the subjects are collected at preset intervals. The oxygen concentration comfort feedback information may specifically include air quality somatosensory feedback information and breathing comfort feedback information. During the oxygen concentration comfort experiment, the oxygen concentration in the experimental environment can be changed at preset intervals to obtain the oxygen concentration comfort feedback information of the subjects under different oxygen concentrations.

[0108] In a specific embodiment, oxygen concentration comfort feedback information of users with different user attributes under different environmental parameters and different oxygen concentrations can be collected through a questionnaire. Figure 3 An example of an oxygen concentration comfort experiment questionnaire is shown in FIG. Figure 3As shown, the main content filled in the questionnaire includes the subject's personal information (i.e. user attribute information, such as gender, age, height, weight) and the current subject's oxygen concentration comfort feedback information, including air quality somatosensory feedback, breathing comfort feedback, etc. For example, air quality somatosensory feedback can be set to 7 levels of indicators, representing the subject's somatosensory indoor air quality, with values ​​of -3, -2, -1, 0, 1, 2, and 3, corresponding to very bad, very bad, bad, moderate, good, very good, and very good states, respectively. Breathing comfort feedback can be set to 4 levels of indicators, representing the subject's comfort level when breathing, with values ​​of 0, 1, 2, and 3, corresponding to very uncomfortable, uncomfortable, comfortable, and very comfortable states, respectively.

[0109] Step S2: establishing an oxygen concentration comfort model based on the collected physiological parameters and oxygen concentration comfort feedback information of the users with different user attributes under different environmental parameters.

[0110] Specifically, user attributes, physiological parameters and environmental parameters are used as input parameters, and oxygen concentration comfort feedback information is used as output parameters to perform model training, and obtain oxygen concentration comfort models for users with different user attributes under different environmental parameters.

[0111] Through experimental design and questionnaires, a large amount of oxygen concentration comfort data was obtained. After statistical analysis of the experimental data, a machine learning algorithm was used to train the data and establish a model for individual oxygen concentration comfort. The collected user attributes, physiological parameters, and environmental parameters were input into the oxygen concentration comfort model to output the current user's oxygen concentration comfort value.

[0112] The second determining unit 130 is configured to determine a current target oxygen concentration according to the oxygen concentration comfort value of the current user determined by the first determining unit 120 .

[0113] In a specific embodiment, the second determining unit 130 determines the current target oxygen concentration according to the determined oxygen concentration comfort value of the current user, including the following situations:

[0114] 1) If the current user's oxygen concentration comfort value is less than a first threshold, the current target oxygen concentration is determined to be the upper limit of the oxygen concentration range that can be set by the oxygen generator.

[0115] That is, the target oxygen concentration is Y, and the oxygen generator can set the upper limit of the oxygen concentration range to Ymax, then Y = Ymax. For example, the first threshold is -2.5, that is, when the oxygen concentration comfort value S < -2.5, the target oxygen concentration is Y = Ymax.

[0116] 2) If the current user's oxygen concentration comfort value is greater than or equal to the first threshold and less than the second threshold, a current target oxygen concentration is determined based on the last determined target oxygen concentration, the set target oxygen concentration change rate corresponding to the current user's oxygen concentration comfort value, and the current user's oxygen concentration comfort value. The last determined target oxygen concentration is the target oxygen concentration last determined based on the user's oxygen concentration comfort value, i.e., the target oxygen concentration last determined when the function of the apparatus of the present invention was last executed.

[0117] The current target oxygen concentration Y is equal to the target oxygen concentration Y0 determined last time plus the product of the set target oxygen concentration change rate KL and the difference between the current user's oxygen concentration comfort value and the second threshold value, that is, Y=Y0+K L ×(S-S2). When the current user's oxygen concentration comfort value is in different oxygen concentration comfort value intervals, different target oxygen concentration change rates are set. When the current user's oxygen concentration comfort value is greater than or equal to the first threshold and less than the second threshold, it is in the poor air quality sensation interval, and the target oxygen concentration change rate K is set. L For example, the first threshold S1 is -2.5, the second threshold S2 is -0.5, and the oxygen concentration comfort value range is -2.5≤S<-0.5, which is in the poor air quality range. The corresponding target oxygen concentration change rate K is set. L , then Y=Y0+K L ×(S+0.5).

[0118] When the current user's oxygen concentration comfort value is greater than or equal to the first threshold and less than the second threshold, the set target oxygen concentration change rate is equal to the slope of a coordinate system with the oxygen concentration comfort as the horizontal axis and the target oxygen concentration as the vertical axis, from a point determined by the upper limit value Ymax of the settable oxygen concentration range of the oxygen concentrator and the minimum value of the oxygen concentration comfort in this interval to a point determined by the last determined target oxygen concentration Y0 and the maximum value of the oxygen concentration comfort in this interval.

[0119] Figure 4 A schematic diagram of the coordinate system of the target oxygen concentration and the current user's oxygen concentration comfort value is shown. Figure 4 As shown, the horizontal axis represents the oxygen concentration comfort level S, and the vertical axis represents the target oxygen concentration Y. For example, when the oxygen concentration comfort level is in the range of -2.5 ≤ S < -0.5, the target oxygen concentration change rate is set as the slope from the point defined by the upper limit of the oxygen concentration range settable by the oxygen generator, Ymax, and the minimum oxygen concentration comfort level in that range, -2.5, to the point defined by the last determined target oxygen concentration, Y0, and the maximum oxygen concentration comfort level in that range, -0.5. In other words, this is the slope of the line whose horizontal axis is in the range of -2.5 ≤ S < -0.5.

[0120] 3) If the current user's oxygen concentration comfort value is greater than or equal to the second threshold and less than the third threshold, the current target oxygen concentration is determined to be equal to the previously determined target oxygen concentration. That is, if the oxygen concentration comfort value is within this oxygen concentration comfort value range, there is no need to adjust the target oxygen concentration; the previously determined target oxygen concentration can be maintained.

[0121] That is, if the target oxygen concentration is Y and the last determined target oxygen concentration is Y0, then Y = Y0. For example, if the second threshold is -0.5 and the third threshold is 0.5, when -0.5 ≤ S < 0.5, there is no need to adjust the target oxygen concentration; the last determined target oxygen concentration can be maintained.

[0122] 4) If the current user's oxygen concentration comfort value is greater than or equal to the third threshold and less than the fourth threshold, the current target oxygen concentration is determined based on the last determined target oxygen concentration, the set target oxygen concentration change rate corresponding to the current user's oxygen concentration comfort value, and the current user's oxygen concentration comfort value.

[0123] The current target oxygen concentration Y is equal to the target oxygen concentration Y0 determined last time plus the product of the set target oxygen concentration change rate KH and the difference between the current user's oxygen concentration comfort value and the third threshold value, that is, Y=Y0+K H ×(S-S3). When the current user's oxygen concentration comfort value is in different oxygen concentration comfort value intervals, different target oxygen concentration change rates are set. When the current user's oxygen concentration comfort value is greater than or equal to the third threshold and less than the fourth threshold, it is in a good air quality feeling interval, corresponding to the set target oxygen concentration change rate KH. For example, when the third threshold S3 is 0.5, the fourth threshold S4 is 2.5, and the oxygen concentration comfort value interval is 0.5≤S<2.5, it is in a good air quality feeling interval, corresponding to the set target oxygen concentration change rate K H , then Y=Y0+K H ×(S-0.5).

[0124] The current user's oxygen concentration comfort value is greater than or equal to the third threshold and less than the fourth threshold. The set target oxygen concentration change rate is equal to the slope of a coordinate system with oxygen concentration comfort as the horizontal axis and target oxygen concentration as the vertical axis, from a point determined by a lower limit value Ymin of the settable oxygen concentration range of the oxygen generator and the maximum value of the oxygen concentration comfort in the interval to a point determined by a previously determined target oxygen concentration Y0 and the minimum value of the oxygen concentration comfort in the interval.

[0125] Figure 4 A schematic diagram of the coordinate system of the target oxygen concentration and the current user's oxygen concentration comfort value is shown. Figure 4As shown, the horizontal axis represents the oxygen concentration comfort level S, and the vertical axis represents the target oxygen concentration Y. For example, when the oxygen concentration comfort level is in the range of 0.5 ≤ S < 2.5, the target oxygen concentration change rate is set to the slope from the point defined by the lower limit of the oxygen concentration range (Ymin) of the oxygen generator and the maximum oxygen concentration comfort level (2.5) in that range to the point defined by the previously determined target oxygen concentration (Y0) and the minimum oxygen concentration comfort level (0.5) in that range. In other words, this is the slope of the line whose horizontal axis is in the range of 0.5 ≤ S < 2.5.

[0126] 5) If the current user's oxygen concentration comfort value is greater than or equal to the fourth threshold, the current target oxygen concentration is determined to be the lower limit of the oxygen concentration range that can be set by the oxygen generator.

[0127] That is, the target oxygen concentration is Y, and the oxygen production equipment can set the lower limit of the oxygen concentration range to Ymin, that is, Y = Ymin. For example, the fourth threshold is 2.5, when S ≥ 2.5, the target oxygen concentration Y = Ymin.

[0128] According to the above embodiment, the current target oxygen concentration is determined according to the current user's oxygen concentration comfort value being in different comfort intervals, which can more accurately determine the target oxygen concentration suitable for the current user.

[0129] The control unit 140 is configured to control the operation of the oxygen production equipment according to the current target oxygen concentration determined by the second determining unit 140 .

[0130] Specifically, the control unit controls the operation of the oxygen generator according to the current target oxygen concentration determined by the second determination unit, including: determining a target operating time and a target operating power required for the oxygen generator to achieve the current target oxygen concentration in the space; and controlling the oxygen generator to operate according to the determined target operating time and target operating power.

[0131] Among them, different target oxygen concentrations correspond to different target operating times and target operating powers. The target operating time and target operating power required by the oxygen production equipment corresponding to the current target oxygen concentration can be determined based on the pre-set correspondence between the target oxygen concentration, the target operating time, and the target operating power. For example, a database of operating time and operating power can be pre-constructed, in which target operating times and target operating powers corresponding to multiple target oxygen concentrations are pre-stored. The target oxygen concentration is matched with the multiple target oxygen concentrations in the database, and the time and power corresponding to the successfully matched target oxygen concentration are determined as the target operating time and target operating power. The oxygen production equipment is controlled to operate at the target operating time and target operating power, so that the oxygen concentration in the space can be adjusted to the target oxygen concentration as soon as possible.

[0132] Figure 9 FIG. 1 is a structural block diagram of another embodiment of the control device for the oxygen production equipment provided by the present invention. Figure 9 As shown, based on the above embodiment, according to another embodiment of the present invention, the control device 100 further includes: an acquisition unit 150.

[0133] The acquisition unit 150 is configured to acquire the oxygen concentration of the space after the oxygen generator is controlled to operate for a preset time according to the current target oxygen concentration determined by the second determination unit 130. The control unit is further configured to determine whether the oxygen concentration in the space is less than the current target oxygen concentration; if so, control the oxygen generator to continue operating; if not, control the oxygen generator to shut down.

[0134] Specifically, after controlling the oxygen production equipment to run for a preset time according to the target oxygen concentration, the oxygen concentration of the space can be detected by an oxygen detection module (such as an oxygen concentration sensor). If the oxygen concentration in the space is less than the target oxygen concentration, it means that the running time of the oxygen production equipment is not long enough and is not enough to meet the needs of the user. At this time, the oxygen production equipment is controlled to continue running. The indoor oxygen concentration is increased by the operation of the oxygen production equipment to reach the target oxygen concentration. After the oxygen production equipment is controlled to continue running, the indoor oxygen concentration is continued to be monitored in order to better adjust the indoor air quality. If the oxygen concentration in the space is greater than or equal to the target oxygen concentration, it means that the indoor oxygen concentration is sufficient and can meet the needs of the user. At this time, the oxygen production equipment is controlled to stop running.

Based on the individual differentiated comfort experience and guided by human comfort, it realizes adaptive control of the operation of air-conditioning oxygen production equipment to meet the user's oxygen concentration comfort needs.
