[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0043] It should be noted that with the development of the automotive industry and the increasing demand for healthy travel, on-board oxygen generation technology has gradually become an important research direction for automotive comfort configuration. When driving in plateau areas or in a closed cabin environment for a long time, although the oxygen content in the air remains at 20.9%, the oxygen partial pressure decreases due to the decrease in atmospheric pressure, and the actual oxygen intake of the human body decreases, which can easily cause altitude sickness or fatigue driving symptoms. Therefore, new vehicles are equipped with on-board oxygen generation systems to ensure the human body's oxygen intake. However, the on-board oxygen generation systems in related technologies cannot achieve intelligent control and have the problem of high energy consumption.

[0044] To address the above-mentioned issues, embodiments of the present invention provide a vehicle-mounted oxygen production control method, device, vehicle-mounted oxygen production system, and electronic equipment. By controlling the start or stop of oxygen production based on an oxygen supply demand value determined based on environmental conditions and passenger conditions, oxygen production can be ensured to be performed only when there is an oxygen supply demand, thereby significantly reducing energy consumption.

[0045] Figure 1 This is a flow chart of a vehicle-mounted oxygen production control method provided by an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0046] Step 101: Obtain the oxygen partial pressure in the cockpit, the altitude of the environment, and the blood oxygen saturation of the passengers in the cockpit.

[0047] In some embodiments, the oxygen partial pressure in the cockpit can be obtained by an oxygen sensor installed in the vehicle. The altitude of the environment refers to the altitude of the environment in which the vehicle is located, and can be obtained by components such as accelerometers and gyroscopes installed in the vehicle. The blood oxygen saturation of passengers in the cockpit can be obtained by a blood oxygen detector installed in the vehicle. For example, a blood oxygen detector that detects by finger pressing can be installed on the side of the seat to detect the blood oxygen saturation of the passengers.

[0048] In some embodiments, step 101 may be executed after receiving a passenger's trigger operation to turn on the oxygen supply, wherein the trigger operation to turn on the oxygen supply may be triggered by a button, a touch screen click, a voice interaction trigger, or the like. Usually, in vehicles equipped with an on-board oxygen supply system, when a passenger turns on the oxygen supply switch, the on-board oxygen supply system starts to supply oxygen. However, there may be cases where a passenger accidentally touches the oxygen supply switch, or forgets to turn it off after turning it on, which will cause a waste of oxygen supply from the on-board oxygen supply system and increase the energy consumption of the on-board oxygen supply system. The present invention can realize intelligent control of oxygen production through the control process of steps 101 to 103, thereby avoiding waste of oxygen supply and reducing the energy consumption of the on-board oxygen supply system.

[0049] Step 102: Determine the oxygen supply requirement based on the oxygen partial pressure, altitude, and blood oxygen saturation.

[0050] As altitude increases, atmospheric pressure decreases, leading to a decrease in the ambient oxygen partial pressure. This decrease in ambient oxygen partial pressure reduces alveolar diffusion, resulting in a decrease in alveolar oxygen partial pressure and arterial oxygen partial pressure. Blood oxygen saturation reflects the ratio of hemoglobin to oxygen, which is affected by arterial oxygen partial pressure. Therefore, oxygen partial pressure, altitude, and blood oxygen saturation are all related to the passenger's current oxygen intake. If oxygen intake decreases, the vehicle's onboard oxygen supply system will be required.

[0051] In some embodiments, the oxygen demand value is used to represent the degree of oxygen demand in the cockpit. If the oxygen demand value is high, it indicates that the oxygen intake of the passengers in the cockpit is low and additional oxygen supply is required to meet the passengers' oxygen intake. If the oxygen demand value is low, it indicates that the oxygen intake of the passengers in the cockpit can meet the human body's oxygen intake needs and no additional oxygen supply is required.

[0052] As a possible implementation process, determining the oxygen demand value based on oxygen partial pressure, altitude, and blood oxygen saturation may include: determining the current passenger's oxygen intake based on the oxygen partial pressure, altitude, and blood oxygen saturation; obtaining the oxygen demand value based on a preset oxygen input baseline value and the current passenger's oxygen intake. For example, a first correspondence between altitude and oxygen intake, a second correspondence between oxygen partial pressure and oxygen intake, and a third correspondence between blood oxygen saturation and oxygen intake may be pre-established; determining a first oxygen intake corresponding to the current oxygen partial pressure based on the second correspondence; determining a second oxygen intake corresponding to the current altitude based on the first correspondence; determining a third oxygen intake corresponding to the current blood oxygen saturation based on the third correspondence; performing a weighted sum calculation on the first, second, and third oxygen intakes, and determining the calculated result as the current passenger's oxygen intake; and determining the oxygen demand value as the difference between the preset oxygen intake baseline value and the current passenger's oxygen intake. This embodiment establishes a mapping relationship between altitude, oxygen partial pressure, blood oxygen saturation and oxygen intake, and compares it with the baseline value after weighted summation. This can comprehensively reflect the influence of multiple factors, avoid misjudgment of a single parameter, and improve the accuracy of the demand value. Furthermore, based on the difference between the current passenger's oxygen intake and the preset oxygen intake baseline value as the oxygen supply demand value, the deviation between the passenger's actual oxygen intake and the baseline value can be directly quantified, achieving close coupling with the passenger's physiological parameters, thereby more intuitively reflecting the passenger's physical condition and providing a reference basis for subsequent control of the oxygen production module.

[0053] As another possible implementation, determining the oxygen demand value based on oxygen partial pressure, altitude, and blood oxygen saturation can include: pre-establishing a first relationship table between oxygen partial pressure, altitude, and arterial partial pressure, and a second relationship table between human arterial partial pressure, human blood oxygen saturation, and oxygen demand values; determining the corresponding arterial partial pressure for the oxygen partial pressure in the cockpit and the altitude of the environment based on the first relationship table; and determining the corresponding oxygen demand value for the passenger's blood oxygen saturation and the obtained arterial partial pressure based on the second relationship table. This embodiment establishes two relationship tables: the first relationship table converts environmental parameters (oxygen partial pressure, altitude) into physiological indicators, namely arterial partial pressure; the second relationship table combines arterial partial pressure and blood oxygen saturation to output the demand value. Compared to the previous embodiment, this avoids the problem of weighted coefficient adjustment, simplifies the calculation process, and reduces the complexity of real-time calculations through a hierarchical table lookup, thereby reducing the requirements for vehicle hardware performance.

[0054] Step 103: Based on the oxygen supply demand value, the oxygen production module is controlled to start or stop oxygen production.

[0055] Since the oxygen demand value is used to represent the degree of oxygen demand for passengers in the cockpit, it can be determined whether the cockpit needs oxygen production by an oxygen production module based on the oxygen demand value. The oxygen production module can be a component used to produce oxygen in the vehicle's oxygen production system.

[0056] In some embodiments, the process of controlling the oxygen production module to start or stop oxygen production based on the oxygen demand value may include: if the oxygen demand value is greater than or equal to a demand threshold, controlling the oxygen production module to start oxygen production; if the oxygen demand value is less than the demand threshold, controlling the oxygen production module to stop oxygen production. The demand threshold may be pre-set based on actual scenarios.

[0057] In some embodiments of the present invention, the oxygen production module may include an air compressor and an oxygen concentrator, wherein the compressor is used to pressurize the external air, and the oxygen concentrator is used to produce oxygen based on the pressurized air through molecular sieve adsorption technology. When the oxygen supply demand value is greater than or equal to the demand threshold, the air compressor is controlled to turn on, and when the oxygen supply demand value is less than the demand threshold, the air compressor is controlled to turn off. The air compressor in the oxygen production module can be a vehicle air suspension compressor, that is, shared with the vehicle air suspension compressor, which can not only optimize the pipeline layout, reduce pressure loss, and improve the gas source utilization rate, but also save space and reduce costs, and also improve reliability.

[0058] According to an embodiment of the present invention, the vehicle-mounted oxygen production control method obtains the oxygen partial pressure in the cockpit, the altitude of the environment, and the blood oxygen saturation of the passengers in the cockpit; determines the oxygen demand value based on the oxygen partial pressure, altitude, and blood oxygen saturation; and controls the oxygen production module to start or stop oxygen production based on the oxygen demand value. By controlling the start and stop of the oxygen production module based on the oxygen demand value, the present invention can avoid the waste caused by starting the oxygen production module when oxygen supply is not needed, thereby significantly reducing the energy consumption of vehicle-mounted oxygen production.

[0059] Figure 2 This is a flow chart of another on-vehicle oxygen production control method provided by an embodiment of the present invention. Figure 2 As shown, based on the above embodiment, Figure 1 The implementation process of step 102 may include the following steps:

[0060] Step 201: Determine a first oxygen supply demand value based on the oxygen partial pressure and an oxygen partial pressure reference value.

[0061] In some embodiments, the oxygen partial pressure reference value may be an oxygen partial pressure that can meet the normal oxygen intake of the human body, such as the oxygen partial pressure under standard atmospheric pressure. Based on the oxygen partial pressure and the oxygen partial pressure reference value, the implementation process of determining the first oxygen supply demand value may include: determining the oxygen partial pressure difference between the oxygen partial pressure reference value and the oxygen partial pressure in the cockpit; multiplying the oxygen partial pressure difference by a preset proportional coefficient to obtain the first oxygen supply demand value. This embodiment directly reflects the physical quantity of the missing oxygen partial pressure by multiplying the deviation between the oxygen partial pressure reference value and the measured value of the oxygen partial pressure (i.e., the oxygen partial pressure in the cockpit) by the proportional coefficient. The result obtained can intuitively represent the calculation result, which is convenient for connecting with the subsequent oxygen supply control. Furthermore, the preset proportional coefficient can be adjusted in combination with the actual application scenario to meet the application needs of different scenarios, improve the matching degree between the oxygen production control process and the actual scenario, and improve the oxygen production effect.

[0062] In other embodiments, determining the first oxygen supply requirement based on the oxygen partial pressure and the oxygen partial pressure baseline may include: determining a first ratio of the oxygen partial pressure in the cockpit to the oxygen partial pressure baseline; and determining the first oxygen supply requirement based on the first ratio. As an example, the difference between 1 and the first ratio may be determined as the first oxygen supply requirement, as shown in the following formula (1).

[0063]

[0064] Among them, Q1 is the first oxygen supply demand value; is the oxygen partial pressure in the cockpit; is the oxygen partial pressure baseline value. This embodiment calculates the oxygen partial pressure in the cockpit and the oxygen partial pressure baseline value, normalizes the oxygen partial pressure in the cockpit, and obtains a relative ratio. The difference between 1 and the obtained ratio is used as the first oxygen supply demand value. Through dimensionless processing, Q1 can directly represent the percentage of hypoxia, facilitating weighted evaluation and improving the compatibility of multi-dimensional data sources.

[0065] Step 202: Determine a second oxygen supply requirement value based on the altitude and the altitude reference value.

[0066] In some embodiments, the altitude reference value may be a pre-set altitude at which normal human oxygen intake is achieved without additional oxygen supply. Determining the second oxygen demand value based on the altitude and the altitude reference value may include: determining the difference between the altitude of the environment and the altitude reference value; and multiplying the difference by a preset change in oxygen demand per unit altitude to obtain the second oxygen demand value.

[0067] In other embodiments, the altitude reference value may be the altitude change corresponding to the unit oxygen demand value, that is, the altitude change corresponding to each increase in the unit oxygen demand value. For example, for every 5000m increase in altitude, the oxygen demand value is increased by one unit, and the altitude reference value is 5000m. Based on the altitude and the altitude reference value, the implementation process of determining the second oxygen demand value may include: determining a second ratio of the altitude of the environment to the altitude reference value, and determining the second ratio as the second oxygen demand value. For example, as shown in the following formula (2), the altitude reference value is 5000m, the altitude of the current environment is 2500m, and the second oxygen demand value is 0.5.

[0068]

[0069] Where Q2 is the second oxygen supply demand value; H is the altitude of the environment; H ′ The altitude reference value.

[0070] Step 203: Determine a third oxygen supply demand value based on the blood oxygen saturation and the blood oxygen saturation baseline value.

[0071] The blood oxygen saturation reference value may be the blood oxygen saturation of a human body under normal circumstances. For example, under normal circumstances, the blood oxygen saturation of a human body should be above 98%, and the blood oxygen saturation reference value may be 98%.

[0072] In some embodiments, the process of determining the third oxygen supply demand value based on the blood oxygen saturation and the blood oxygen saturation baseline value may include: determining the difference between the blood oxygen saturation baseline value and the passenger's blood oxygen saturation; and multiplying the difference by a preset proportional coefficient to determine the third oxygen supply demand value.

[0073] In other embodiments, determining the third oxygen demand value based on the blood oxygen saturation and the blood oxygen saturation baseline value may include: determining a third ratio of the passenger's blood oxygen saturation to the blood oxygen saturation baseline value; and determining the third oxygen demand value based on the third ratio. As an example, as shown in the following formula (3), the difference obtained by subtracting the third ratio from 1 may be determined as the third oxygen demand value.

[0074]

[0075] Among them, Q3 is the third oxygen supply demand value; The passenger's blood oxygen saturation; It is the baseline value of blood oxygen saturation.

[0076] It should be noted that in the aforementioned calculation process, the first oxygen demand value and the third oxygen demand value are both the results obtained by subtracting the corresponding ratio from 1. This calculation allows Q1 and Q3 to directly quantify the degree to which the current state deviates from the ideal value. The larger the value of the result, the more urgent the demand, thereby directly representing the oxygen demand state based on the results of Q1 and Q3. The reason why Q2 is not calculated by subtracting 1 is that the baseline value of the altitude is essentially the critical altitude for triggering oxygen supply. Formula (2) converts the altitude into a relative altitude coefficient (i.e., a ratio). Since the degree of hypoxia in the plateau increases monotonically with altitude, Q2 itself already expresses the intensity of oxygen demand. Subtracting it will reverse the physical meaning. Therefore, when calculating Q2, there is no need to subtract it from 1. Based on this, the results of Q1, Q2, and Q3 can all intuitively represent the intensity of oxygen demand, thereby meeting the requirements of subsequent calculation of oxygen demand values.

[0077] Step 204: Determine an oxygen supply requirement value based on the first oxygen supply requirement value, the second oxygen supply requirement value, and the third oxygen supply requirement value.

[0078] In some embodiments, the average of the first oxygen demand value, the second oxygen demand value, and the third oxygen demand value may be used as the oxygen demand value.

[0079] Because oxygen partial pressure, altitude, and blood oxygen saturation may have different impacts on the oxygen demand value, in some embodiments, weight coefficients for the first oxygen demand value, the second oxygen demand value, and the third oxygen demand value may be pre-set based on actual needs. Determining the oxygen demand value based on the first oxygen demand value, the second oxygen demand value, and the third oxygen demand value may include performing a weighted sum calculation on the first oxygen demand value, the second oxygen demand value, and the third oxygen demand value, and determining the oxygen demand value based on the calculation result.

[0080] According to the on-board oxygen production control method of an embodiment of the present invention, an oxygen supply demand value is obtained by combining a first oxygen supply demand value determined by oxygen partial pressure, a second oxygen supply demand value determined by altitude, and a third oxygen supply demand value determined by blood oxygen saturation. The obtained oxygen supply demand value is made more consistent with the current scenario, thereby improving the accuracy of on-board oxygen production control.

[0081] Figure 3 A flow chart of another on-vehicle oxygen production control method provided by an embodiment of the present invention. Figure 3 As shown, the method may include the following steps:

[0082] Step 301: Obtain the oxygen partial pressure in the cockpit, the altitude of the environment, and the blood oxygen saturation of the passengers in the cockpit.

[0083] Step 302: Determine the oxygen supply requirement based on the oxygen partial pressure, altitude, and blood oxygen saturation.

[0084] Step 303: Based on the oxygen supply demand value, the oxygen production module is controlled to start or stop oxygen production.

[0085] In step 304 , if the oxygen production module starts to produce oxygen, a target oxygen supply mode is determined, and the produced oxygen is supplied to the cockpit through the target oxygen supply mode.

[0086] In some embodiments, after the oxygen production module starts to produce oxygen, the produced oxygen can be supplied to the cockpit through the oxygen supply channel to provide additional oxygen for passengers.

[0087] However, in different scenarios, passengers' demand for oxygen varies. For example, if a passenger has severe altitude sickness, he or she needs to inhale a higher concentration of oxygen to adjust the physical discomfort as soon as possible. If the oxygen demand is not high, the passenger does not need to inhale a high concentration of oxygen.

[0088] In order to take into account different oxygen supply scenarios, the target oxygen supply mode can be determined first, and then the target oxygen supply mode can be used to supply the produced oxygen to the cockpit. Among them, the cockpit can support multiple oxygen supply modes, each of which can supply oxygen at different concentrations. For example, the cockpit can be equipped with different oxygen supply channels, including diffuse oxygen supply channels and oxygen mask supply channels. The oxygen supply modes can include oxygen mask oxygen supply mode (oxygen concentration ≥ 90%) and diffuse oxygen supply mode (oxygen concentration ≤ 23.5%). In the oxygen mask mode, oxygen is supplied to passengers through the oxygen mask channel, and in the diffuse oxygen supply mode, oxygen is supplied to the cockpit through the diffuse oxygen supply channel.

[0089] In some embodiments, the target oxygen supply mode can be determined based on one or more indicators: oxygen partial pressure in the cockpit, altitude, or passenger's blood oxygen saturation. As an example, the cockpit is equipped with two oxygen supply modes, including a first oxygen supply mode and a second oxygen supply mode, where the oxygen concentration supplied by the first oxygen supply mode is greater than the oxygen concentration supplied by the second oxygen supply mode; if the altitude is greater than or equal to an altitude threshold, the target oxygen supply mode is determined to be the first oxygen supply mode; if the altitude is less than the altitude threshold, the target oxygen supply mode is determined to be the second oxygen supply mode.

[0090] As a possible implementation method, the cockpit is equipped with a diffusion oxygen supply channel and a nasal oxygen supply channel. The diffusion oxygen supply channel includes an oxygen supply pipe and a diffusion air outlet. Oxygen is transported to the diffusion air outlet through the oxygen supply pipe, and the diffusion air outlet evenly distributes the oxygen (the peak oxygen concentration is 23.5%). Among them, the diffusion air outlet can be an air-conditioning outlet in the cockpit. The nasal oxygen supply channel may include an oxygen supply pipe and a nasal oxygen outlet. Oxygen is transported to the nasal oxygen outlet through the oxygen supply pipe, and the nasal oxygen outlet provides oxygen with a concentration of ≥90%. The diffusion oxygen supply mode supplies oxygen through the diffusion oxygen supply channel, and the nasal oxygen supply mode supplies oxygen through the nasal oxygen supply channel.

[0091] In the above scenario, the implementation method of determining the target oxygen supply mode may include: if the blood oxygen saturation is less than or equal to the blood oxygen saturation threshold, determining the target oxygen supply mode as the nasal oxygen supply mode. The nasal oxygen supply mode has a more targeted oxygen supply process and can directly act on passengers with low blood oxygen saturation, thereby providing centralized and efficient oxygen supply to passengers with low blood oxygen saturation and effectively ensuring the life safety of passengers; if the blood oxygen saturation is greater than the blood oxygen saturation threshold, determining the target oxygen supply mode as the diffuse oxygen supply mode. At this time, the passenger's blood oxygen saturation can meet the life safety needs. The use of the diffuse oxygen supply mode can improve the overall oxygen supply in the cockpit. The oxygen level in the human body helps to improve the riding experience and health status of all passengers in the cockpit. The blood oxygen saturation threshold can be set based on actual needs, such as 85%. Of course, it is understandable that other blood oxygen saturation thresholds can be further set, such as 90%. Based on this, when the passenger's blood oxygen saturation is higher than 90%, it means that the passenger's own condition is not affected by environmental factors such as high altitude, and there is no need for the vehicle to provide oxygen to the cockpit separately. In this case, in order to effectively reduce the energy consumption of the oxygen production process, the oxygen production module can be controlled to enter standby mode and oxygen production can be suspended.

[0092] As an example, when the oxygen supply button in the cockpit is triggered, the oxygen supply demand value is determined based on the oxygen partial pressure in the cockpit, the altitude of the environment and the passenger's blood oxygen saturation. If the oxygen supply demand value is greater than or equal to the demand threshold, the oxygen production module is controlled to start oxygen production; after starting oxygen production, if the passenger's blood oxygen saturation is less than or equal to 85%, the vehicle speaker is controlled to issue a voice prompt "The current oxygen supply mode is nasal oxygen supply mode", and oxygen is supplied to the cockpit through the nasal oxygen supply channel; if the passenger's blood oxygen saturation is greater than 85%, the vehicle speaker is controlled to issue a voice prompt "The current oxygen supply mode is diffuse oxygen supply mode", and oxygen is supplied to the cockpit through the diffuse oxygen supply channel.

[0093] In some embodiments, the number of target oxygen supply modes can also be multiple. For example, there are three passengers in the cockpit at present, and the oxygen supply demand value can be calculated based on the lowest value of the blood oxygen saturation of each of the three passengers. If the cockpit is equipped with two nasal oxygen supply channels and one diffuse oxygen supply channel, after starting oxygen production, the blood oxygen saturation of each passenger can be compared with the blood oxygen saturation threshold. If the blood oxygen saturation of two of the passengers is less than or equal to the blood oxygen saturation threshold, and the blood oxygen saturation of the other passenger is greater than the blood oxygen saturation threshold, then the target oxygen supply mode is the diffuse oxygen supply mode + nasal oxygen supply mode, and the generated oxygen is supplied to the passengers whose blood oxygen saturation is less than or equal to the blood oxygen saturation threshold through two nasal oxygen supply channels, and to the passengers whose blood oxygen saturation is greater than the blood oxygen saturation threshold through one diffuse oxygen supply channel. If the blood oxygen saturation of each passenger is greater than the blood oxygen saturation threshold, the target oxygen supply mode is the diffusion oxygen supply mode, and the generated oxygen is supplied to the cockpit only through the diffusion oxygen supply channel; if the blood oxygen saturation of only one passenger is less than or equal to the blood oxygen saturation threshold, the target oxygen supply mode is the diffusion oxygen supply mode + nasal oxygen supply mode, and the generated oxygen is supplied to the passengers whose blood oxygen saturation is less than or equal to the blood oxygen saturation threshold through one nasal oxygen supply channel, and supplied to the cockpit through one diffusion oxygen supply channel, and oxygen is supplied to the other two passengers whose blood oxygen saturation is greater than the blood oxygen saturation threshold.

[0094] It should be noted that in actual application scenarios, the determined target oxygen supply mode can remind passengers through voice or other means in the car, the oxygen supply of the target oxygen supply mode can be automatically triggered, or the passengers can decide whether to trigger the oxygen supply of the target oxygen supply mode.

[0095] According to the vehicle-mounted oxygen production control method of an embodiment of the present invention, after starting oxygen production, the target oxygen supply mode that matches the current actual situation can be determined first, and the produced oxygen can be supplied to the cockpit through the target oxygen supply mode. By automatically switching different oxygen supply modes, the oxygen supply needs in different scenarios can be met.

[0096] In order to implement the above embodiment, the present invention also provides a vehicle-mounted oxygen production control device.

[0097] Figure 4 This is a schematic diagram of the structure of a vehicle-mounted oxygen production control device provided by an embodiment of the present invention. Figure 4 As shown, the device may include: an acquisition module 410 , a first determination module 420 and a control module 430 .

[0106] As a possible implementation manner, the first determining module 420 is further configured to:

[0107] The first oxygen supply requirement value, the second oxygen supply requirement value, and the third oxygen supply requirement value are weightedly summed and calculated, and the oxygen supply requirement value is determined based on the calculation result.

[0108] In some embodiments, the control module 430 is specifically configured to:

[0109] If the oxygen supply demand value is greater than or equal to the demand threshold, controlling the oxygen production module to start oxygen production;

[0110] If the oxygen supply demand value is less than the demand threshold, the oxygen production module is controlled to stop oxygen production.

[0111] In some embodiments, the apparatus further comprises:

[0112] The second determining module 440 is configured to determine a target oxygen supply mode if the oxygen production module starts to produce oxygen, and supply the produced oxygen into the cockpit through the target oxygen supply mode.

[0113] As a possible implementation, the cockpit is equipped with a diffuse oxygen supply channel and a nasal oxygen supply channel; the second determining module 440 is further configured to:

[0114] If the blood oxygen saturation is less than or equal to the blood oxygen saturation threshold, determining that the target oxygen supply mode is the nasal breathing oxygen supply mode;

[0115] If the blood oxygen saturation is greater than the blood oxygen saturation threshold, it is determined that the target oxygen supply mode is the diffusion oxygen supply mode.

[0116] In some embodiments, the compressor in the oxygen production module is a vehicle air suspension compressor.

[0117] According to an embodiment of the present invention, the on-board oxygen production control device obtains the oxygen partial pressure in the cockpit, the altitude of the environment, and the blood oxygen saturation of the passengers in the cockpit; determines the oxygen demand value based on the oxygen partial pressure, altitude, and blood oxygen saturation; and controls the oxygen production module to start or stop oxygen production based on the oxygen demand value. By controlling the start and stop of the oxygen production module based on the oxygen demand value, the present invention can avoid the waste caused by starting the oxygen production module when oxygen supply is not needed, thereby significantly reducing the energy consumption of on-board oxygen production.

[0118] It should be noted that the explanations in the above embodiment of the vehicle-mounted oxygen production control method are also applicable to the vehicle-mounted oxygen production control device in the embodiment of the present invention, and will not be repeated here.

[0119] In order to implement the above embodiment, the present invention also provides a vehicle-mounted oxygen production system.

[0120] Figure 5 This is a structural diagram of a vehicle-mounted oxygen production system provided by an embodiment of the present invention. Figure 5 As shown, the vehicle-mounted oxygen production system includes an oxygen production module 510, an oxygen supply module 520, and a control module 530. The oxygen production module 510 is configured to produce oxygen from external air; the oxygen supply module 520 is connected to the oxygen production module 510 and is configured to supply the oxygen produced by the oxygen production module to the cockpit; and the control module 530 is connected to the oxygen production module 510 and may also be connected to the oxygen supply module 520 to execute the vehicle-mounted oxygen production control method described in the above embodiments.

[0121] In some embodiments, the oxygen production module 510 may include an air source processing unit and a PSA oxygen production unit. The air source processing unit includes a dust removal filter, an air compressor and a condenser. The dust removal filter is connected to the air compressor, and the air compressor is connected to the condenser. Among them, the air compressor can be an air suspension compressor, that is, shared with the vehicle air suspension compressor, which can not only optimize the pipeline layout, reduce pressure loss, and improve the utilization rate of the air source, but also save space and reduce costs, and also improve reliability. The PSA oxygen production unit includes a solenoid valve group, a molecular sieve tower (Tower A) and a molecular sieve tower (Tower B). The solenoid valve group is used to control the adsorption / desorption cycle and is connected to Tower A and Tower B respectively.

[0122] As a possible implementation, the oxygen supply module 520 may include an oxygen storage tank, a diffusion oxygen supply channel and a nasal oxygen supply channel. The oxygen storage tank is connected to the diffusion oxygen supply channel and the nasal oxygen supply channel respectively. Among them, the diffusion outlet corresponding to the diffusion oxygen supply channel can be an air-conditioning outlet in the cockpit, and the nasal oxygen outlet corresponding to the nasal oxygen supply channel can be a dedicated oxygen mask. The number of nasal oxygen supply channels can be multiple. The peak oxygen concentration supplied by the diffusion oxygen supply channel is 23.5%, and the flow rate is 3-5L / min. The oxygen concentration supplied by the nasal oxygen supply channel is ≥90%, and the flow rate is 1-3L / min. The oxygen storage tank is used to buffer pressure fluctuations.

[0123] In some embodiments, the vehicle-mounted oxygen supply system may further include an oxygen sensor for detecting the oxygen partial pressure in the cockpit. The control module 530 is connected to the oxygen sensor and the CAN bus. The CAN bus can input the altitude detected by the vehicle-mounted detection device and the passenger's blood oxygen saturation into the control module 530, and can also send the operation instructions issued by the passenger based on the user interface to the control module 530. The control module 530 executes the vehicle-mounted oxygen production control method in the above embodiment based on the received data. The control module 530 can be connected to the air compressor, the solenoid valve group, and the nasal oxygen supply channel and the diffused oxygen supply channel.

[0124] As a possible implementation method, the molecular sieve tower in the PSA oxygen production unit adopts a dual-tower pressure swing adsorption method, which specifically includes: (1) adsorption stage (0-5s), compressed air enters tower A, the molecular sieve adsorbs nitrogen, oxygen passes through, and tower B desorbs and regenerates at the same time; (2) equalization stage (5-7s), the high-pressure gas of tower A is partially introduced into tower B to balance the pressure of the two towers to 0.35MPa; (3) desorption stage (7-12s), tower A is depressurized to 0.15MPa, and the adsorbed nitrogen is discharged through the muffler; (4) switching stage (12-15s), the roles of the two towers are exchanged, and the solenoid valve group switches the direction of the gas path.

[0125] In some embodiments, to reduce cockpit noise, the PSA oxygen generator unit in oxygen generator module 510 is positioned ≥ 2.5 meters from the cockpit. The solenoid valve assembly is centrally located on a silicone shock-absorbing platform, and the molecular sieve tower is positioned with a low center of gravity. The trunk air compressor is seismically isolated using the vehicle's longitudinal beams and floor interlayer, allowing the original vehicle's hydraulic shock-absorbing brackets to be reused. The oxygen delivery pipe adopts a corrugated structure, with pipe clamps installed every 500 mm for damping, and Helmholtz silencers installed at key points.

[0126] In the vehicle-mounted oxygen generation system provided by an embodiment of the present invention, the control module can control the start and stop of the oxygen generation module based on the oxygen supply demand value, significantly reducing the energy consumption of the vehicle-mounted oxygen generation system. The oxygen supply module provides diffuse oxygen supply channels and nasal oxygen supply channels. The control module controls the oxygen supply module to adopt the appropriate oxygen supply mode based on the actual scenario to meet the oxygen supply needs in different scenarios.
