Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0013] At present, the vehicle-mounted oxygen generating equipment mainly adopts physical oxygen generation, in-vehicle diffusion oxygen supply and portable oxygen generator. The in-vehicle diffusion oxygen supply technology mainly adopts pressure swing adsorption (PSA) principle as the core, and needs to rely on the vehicle-mounted power supply. When the vehicle encounters an emergency situation without power, it cannot be used. The portable oxygen generator as an emergency oxygen generating equipment can usually be equipped with a backup power supply, but the emergency oxygen generating equipment is insufficient in linkage with the in-vehicle diffusion oxygen supply equipment due to isolated use. If the situation of needing rescue occurs outdoors in a high-altitude area or a traffic underdeveloped area or the emergency situation of vehicle power failure occurs, the in-vehicle diffusion oxygen supply mode is difficult to meet the oxygen demand of the vehicle personnel.

[0014] Based on this, the vehicle-mounted oxygen supply system, control method and vehicle provided by the embodiments of the present application can alleviate the above problems in the related art.

[0015] In order to facilitate the understanding of the embodiments, first, a vehicle-mounted oxygen supply system disclosed by the embodiments of the present application is introduced in detail, referring to Figure 1 The vehicle-mounted oxygen supply system can include: an electronic control unit 1 of a vehicle and an environment perception module 50 connected with the electronic control unit 1, an oxygen outlet end of a vehicle-mounted oxygen generating equipment 2 connected with an oxygen supply terminal module 4 through a pipeline; the vehicle-mounted oxygen generating equipment 2 adopts a physical oxygen source, and an emergency oxygen generating equipment 3 adopts a physical oxygen source and / or a chemical oxygen source; the environment perception module 50 can be used to collect the in-vehicle and out-vehicle environment information of the vehicle; the electronic control unit 1 can be used to control the vehicle-mounted oxygen generating equipment 2 to supply oxygen through the oxygen supply terminal module 4 and / or control the emergency oxygen generating equipment 3 to supply oxygen based on the in-vehicle and out-vehicle environment information.

[0016] The vehicle-mounted oxygen supply system provided by the embodiment of the present application, the electronic control unit of the vehicle is connected with the environment perception module, the vehicle-mounted oxygen generating device, the emergency oxygen generating device and the oxygen supply terminal module respectively, the oxygen outlet end of the vehicle-mounted oxygen generating device is connected with the oxygen supply terminal module through a pipeline, the vehicle-mounted oxygen generating device adopts a physical oxygen source, the emergency oxygen generating device adopts a physical oxygen source and / or a chemical oxygen source, the vehicle's indoor and outdoor environment information collected by the environment perception module can be used by the electronic control unit to control the vehicle-mounted oxygen generating device to supply oxygen through the oxygen supply terminal module and / or control the emergency oxygen generating device to supply oxygen. By using the above vehicle-mounted oxygen supply system, the intelligent oxygen supply control strategy of different oxygen sources is integrated, the intelligent cooperation of the vehicle-mounted oxygen generating device and the emergency oxygen generating device is realized, the limitations of the existing vehicle-mounted oxygen supply system, such as unable to use in the case of power failure, oxygen consumption seriously exceeding the oxygen supply amount of the vehicle-mounted oxygen supply system and unable to supply oxygen in the plateau outdoor, etc. can be solved, so as to meet the user's multi-scenario demand.

[0017] As a possible implementation, referring to FIGS. 5 and 6, Figure 1 and Figure 2 The environment perception module 50 can include an indoor environment perception module 6 and an outdoor environment perception module 5, and the indoor and outdoor environment information can include the indoor environment information and the outdoor environment information of the vehicle. Based on this, the indoor environment perception module 6 can be used to collect the indoor environment information, wherein the indoor environment information can include the indoor oxygen concentration of the vehicle and the oxygen supply state information of the vehicle-mounted oxygen generating device 2; the outdoor environment perception module 5 can be used to collect the outdoor environment information, wherein the outdoor environment information can include the altitude of the location where the vehicle is located and at least one of the following information of the vehicle: outdoor temperature, outdoor humidity, outdoor atmospheric pressure, outdoor air quality; the electronic control unit 1 can also be used to: determine the altitude grade of the region where the vehicle is located based on the outdoor environment information; based on the altitude grade and the indoor environment information, control the vehicle-mounted oxygen generating device 2 to supply oxygen in a first oxygen supply mode through the oxygen supply terminal module 4 and / or control the emergency oxygen generating device 3 to supply oxygen in a second oxygen supply mode.

[0018] In actual application, a first mapping relationship between the altitude, the outdoor temperature, the outdoor humidity, the outdoor atmospheric pressure, the outdoor air quality and the altitude grade can be established in advance, so that after the electronic control unit 1 obtains the altitude (which can be collected by the altitude sensor installed outside the vehicle), the outdoor temperature (which can be collected by the temperature sensor installed outside the vehicle), the outdoor humidity (which can be collected by the humidity sensor installed outside the vehicle), the outdoor atmospheric pressure (which can be collected by the air pressure sensor installed outside the vehicle) and the outdoor air quality (which can be collected by the air quality sensor installed outside the vehicle) collected by the outdoor environment perception module 5, the altitude grade of the region where the vehicle is located can be determined by using the first mapping relationship.

[0019] In actual application, a second mapping relationship between the altitude, the outside temperature, the outside humidity, the outside atmospheric pressure and the outside air quality and the oxygen supply mode (including the diffused oxygen supply mode and the non-diffused oxygen supply mode) can be established in advance, so that the electronic control unit 1 can determine the first target oxygen supply mode required by the vehicle-mounted oxygen generating device 2 and the second target oxygen supply mode required by the emergency oxygen generating device 3 by using the second mapping relationship after obtaining the altitude, the outside temperature, the outside humidity, the outside atmospheric pressure and the outside air quality collected by the outside environment perception module 5, and then control the vehicle-mounted oxygen generating device 2 to supply oxygen in the target oxygen supply mode through the oxygen supply terminal module 4 and / or control the emergency oxygen generating device 3 to supply oxygen in the second target oxygen supply mode based on the altitude level and the in-vehicle environment information.

[0020] Exemplarily, referring to FIG. 1, Figure 2 As shown in FIG. 1, the altitude level can be divided into low altitude, high altitude and extremely high altitude, the in-vehicle environment information can further include oxygen supply state information of the vehicle-mounted oxygen generating device 2, the first oxygen supply mode can include the diffused oxygen supply mode and the non-diffused oxygen supply mode, and the oxygen supply state information can include the oxygen supply flow rate and the oxygen supply concentration of the vehicle-mounted oxygen generating device 2 in the non-diffused oxygen supply mode; the electronic control unit 1 can perform the following operations: Step A1, if it is determined based on the outside environment information that the vehicle is located in a low-altitude area or a high-altitude area, then based on the in-vehicle oxygen concentration and the oxygen supply state information, the vehicle-mounted oxygen generating device 2 is controlled to supply oxygen in the first oxygen supply mode through the oxygen supply terminal module 4.

[0021] Step A2, if it is determined based on the outside environment information that the vehicle is located in an extremely high-altitude area, then it is determined based on the altitude whether the in-vehicle oxygen concentration or the oxygen supply state information meets the oxygen consumption standard for the extremely high altitude.

[0022] In actual application, a third mapping relationship between the altitude, the in-vehicle oxygen concentration, the oxygen supply flow rate, the oxygen supply concentration and the oxygen consumption standard can be established in advance, so that the electronic control unit 1 can determine the oxygen consumption standard for the extremely high altitude by using the third mapping relationship after obtaining the altitude collected by the outside environment perception module 5 and the in-vehicle oxygen concentration, the oxygen supply flow rate and the oxygen supply concentration collected by the in-vehicle environment perception module 5, and then determine whether the in-vehicle oxygen concentration meets the oxygen consumption standard or whether the oxygen supply flow rate and the oxygen supply concentration meet the oxygen consumption standard.

[0023] Step A3, if the in-vehicle oxygen concentration or the oxygen supply state information meets the oxygen consumption standard for the extremely high altitude, then based on the in-vehicle oxygen concentration and the oxygen supply state information, the vehicle-mounted oxygen generating device 2 is controlled to supply oxygen in the first oxygen supply mode through the oxygen supply terminal module 4.

[0024] In the preceding example, on the basis that the electronic control unit 1 determines the first target oxygen supply mode to be adopted by the vehicle-mounted oxygen generating device 2 by using the second mapping relationship, the electronic control unit 1 further determines whether the in-vehicle oxygen concentration meets the oxygen use standard for extremely high altitudes or whether the oxygen supply flow rate and the oxygen supply concentration meet the oxygen use standard. At this time, the oxygen concentration (including the in-vehicle oxygen concentration and the oxygen supply concentration) and the oxygen flow rate (i.e., the oxygen supply flow rate) can be continuously monitored by the corresponding in-vehicle sensors installed inside the vehicle and fed back to the electronic control unit 1, and the electronic control unit 1 sends the first control instruction corresponding to the first target oxygen supply mode to the vehicle-mounted oxygen generating device 2 and the second control instruction corresponding to the first target oxygen supply mode to the oxygen supply terminal module 4 on the basis of the received oxygen concentration and oxygen flow rate, so as to control the vehicle-mounted oxygen generating device 2 to supply oxygen in the first target oxygen supply mode through the oxygen supply terminal module 4.

[0025] In step A4, if the in-vehicle oxygen concentration or the oxygen supply state information does not meet the oxygen use standard for extremely high altitudes, the current oxygen demand of the vehicle is determined on the basis of the in-vehicle oxygen concentration, the oxygen supply state information, and the oxygen use standard, and the vehicle-mounted oxygen generating device is controlled to supply oxygen in the first oxygen supply mode through the oxygen supply terminal module on the basis of the in-vehicle oxygen concentration and the oxygen supply state information, while the emergency oxygen generating device is controlled to supply oxygen in the second oxygen supply mode on the basis of the current oxygen demand.

[0026] In the preceding example, a fourth mapping relationship between the in-vehicle oxygen concentration, the oxygen supply flow rate, the oxygen supply concentration, the oxygen use standard, and the oxygen demand can be established in advance, so that the electronic control unit 1 can determine the current oxygen demand by using the fourth mapping relationship after obtaining the in-vehicle oxygen concentration, the oxygen supply flow rate, the oxygen supply concentration, and the oxygen use standard corresponding to the altitude level collected by the in-vehicle environment perception module 5. On the basis that the electronic control unit 1 determines that the in-vehicle oxygen concentration does not meet the oxygen use standard for extremely high altitudes or that the oxygen supply flow rate and the oxygen supply concentration do not meet the oxygen use standard by using the third mapping relationship, it is indicated that the emergency oxygen generating device 3 needs to be started to supply oxygen as a supplement to the vehicle-mounted oxygen generating device 2 to meet the oxygen use standard, and the electronic control unit 1 further determines the first target oxygen supply mode to be adopted by the vehicle-mounted oxygen generating device 2 and the second target oxygen supply mode to be adopted by the emergency oxygen generating device 3 by using the second mapping relationship. At this time, the continuously monitored oxygen concentration and oxygen flow rate can be fed back to the electronic control unit 1 by the corresponding in-vehicle sensors installed inside the vehicle, and the electronic control unit 1 sends the first control instruction corresponding to the first target oxygen supply mode to the vehicle-mounted oxygen generating device 2 and the second control instruction corresponding to the first target oxygen supply mode to the oxygen supply terminal module 4 on the basis of the received oxygen concentration and oxygen flow rate, while the electronic control unit 1 sends the third control instruction corresponding to the second target oxygen supply mode to the emergency oxygen generating device 3 on the basis of the determined current oxygen demand, so as to control the vehicle-mounted oxygen generating device 2 to supply oxygen in the first target oxygen supply mode through the oxygen supply terminal module 4 by using the first control instruction and the second control instruction, and control the emergency oxygen generating device 3 to supply oxygen in the second target oxygen supply mode by using the third control instruction.

[0027] As a possible implementation, the second oxygen supply mode can include a diffuse oxygen supply mode and a non-diffuse oxygen supply mode; the in-vehicle environment information can further include an in-vehicle carbon dioxide concentration of the vehicle; based on this, referring to Figure 1 and Figure 2 , the electronic control unit 1 can be further configured to: if the in-vehicle carbon dioxide concentration is higher than a preset concentration threshold, control the on-board oxygen generator 2 to supply oxygen in the first oxygen supply mode through the oxygen supply terminal module 4 based on the in-vehicle oxygen concentration and the oxygen supply state information, and control the emergency oxygen generator 3 to supply oxygen in the diffuse oxygen supply mode based on the in-vehicle carbon dioxide concentration.

[0028] Following the previous example, based on the oxygen supply of the on-board oxygen generator 2 through the oxygen supply terminal module 4, the continuously monitored oxygen concentration, oxygen flow and in-vehicle carbon dioxide concentration can be fed back to the electronic control unit 1 through the in-vehicle sensors installed inside the vehicle, and the electronic control unit 1 determines whether the received in-vehicle carbon dioxide concentration is higher than a preset concentration threshold. If the in-vehicle carbon dioxide concentration is higher than the preset concentration threshold, the electronic control unit 1 sends a fourth control instruction corresponding to the diffuse oxygen supply mode to the emergency oxygen generator 3 based on the in-vehicle carbon dioxide concentration, so as to control the emergency oxygen generator 3 to supply oxygen in the diffuse oxygen supply mode through the fourth control instruction.

[0029] As a possible implementation, referring to Figure 1 and Figure 2 , the emergency oxygen generator 3 can include different oxygen generation modules, and the oxygen generation modules can include at least one physical oxygen generation module using a physical oxygen source; based on this, the electronic control unit 1 can be further configured to: control the emergency oxygen generator to supply oxygen in the second oxygen supply mode through the target oxygen generation module based on the current oxygen demand.

[0030] Exemplarily, after determining the current oxygen demand, the electronic control unit 1 can perform the following steps a1 to a3: Step a1, if the sum of the maximum oxygen supply amounts of the first preset number of physical oxygen generation modules is greater than the current oxygen demand, the first preset number of physical oxygen generation modules are taken as the target oxygen generation module; wherein the first preset number is less than the total number of physical oxygen generation modules.

[0031] Step a2, if the sum of the maximum oxygen supply amounts of the first preset number of physical oxygen generation modules is not greater than the current oxygen demand, it is determined whether the sum of the maximum oxygen supply amounts of all physical oxygen generation modules is greater than the current oxygen demand.

[0032] Step a3, if the sum of the maximum oxygen supply amounts of all physical oxygen generation modules is greater than the current oxygen demand, all physical oxygen generation modules are taken as the target oxygen generation module.

[0033] Exemplarily, the oxygen production module can further include at least one chemical oxygen production module using a chemical oxygen source, and the electronic control unit 1 can further perform the following steps a4 to a6 after determining the current oxygen demand: Step a4, if the sum of the maximum oxygen supply amounts of all physical oxygen production modules is not greater than the current oxygen demand, sum the maximum oxygen supply amounts of all physical oxygen production modules and the maximum oxygen supply amounts of the second preset number of chemical oxygen production modules; wherein the second preset number is less than the total number of chemical oxygen production modules.

[0034] Step a5, if the sum is greater than the current oxygen demand, all physical oxygen production modules and the second preset number of chemical oxygen production modules are used as target oxygen production modules.

[0035] Step a6, if the sum is not greater than the current oxygen demand, all physical oxygen production modules and all chemical oxygen production modules are used as target oxygen production modules.

[0036] As a possible implementation, referring to Figure 1 and Figure 2 The electronic control unit 1 can also be used to: if it is determined based on the vehicle exterior environment information that the vehicle is in an extremely high altitude area, determine whether the in-vehicle oxygen concentration and oxygen supply state information meet the oxygen use standard for extremely high altitude based on the altitude and the number of in-vehicle oxygen users; if the in-vehicle oxygen concentration and oxygen supply state information meet the oxygen use standard for extremely high altitude, control the vehicle-mounted oxygen production device 2 to supply oxygen in the first oxygen supply mode through the oxygen supply terminal module 4 based on the in-vehicle oxygen concentration and oxygen supply state information; if the in-vehicle oxygen concentration and oxygen supply state information do not meet the oxygen use standard for extremely high altitude, update the current oxygen demand based on the in-vehicle oxygen concentration, oxygen supply state information and oxygen use standard, and control the vehicle-mounted oxygen production device 2 to supply oxygen in the first oxygen supply mode through the oxygen supply terminal module 4 based on the in-vehicle oxygen concentration and oxygen supply state information, while controlling the emergency oxygen production device 3 to supply oxygen in the second oxygen supply mode based on the updated oxygen demand.

[0037] For ease of understanding, the architecture and implementation of the above vehicle-mounted oxygen supply system are exemplarily described as follows with specific applications as examples.

[0038] Referring to Figure 2As shown, the vehicle-mounted oxygen supply system comprises: an electronic control unit 1 of a vehicle, and a vehicle-mounted oxygen generating device 2, an emergency oxygen generating device 3, an oxygen supply terminal module 4, an off-vehicle environment sensing module 5 and an in-vehicle environment sensing module 6 connected with the electronic control unit 1, the oxygen outlet of the vehicle-mounted oxygen generating device 2 is connected with the oxygen supply terminal module 4 through a pipeline; the electronic control unit 1 can intelligently adjust the oxygen supply amount and the oxygen supply mode by using a multi-modal fusion algorithm according to the sensor data collected by the off-vehicle environment sensing module 5 and the in-vehicle environment sensing module 6; the oxygen source of the vehicle-mounted oxygen generating device 2 uses but is not limited to a physical oxygen source (such as oxygen generation by using an air compressor combined with an oxygen concentrator); the oxygen source of the emergency oxygen generating device 3 uses but is not limited to a chemical oxygen source (such as chemical solid-state oxygen generation and chemical liquid-state oxygen generation) and / or a physical oxygen source (such as oxygen generation by using a portable oxygen generator), the emergency oxygen generating device 3 can be designed in a multi-module combination, and the oxygen supply amount of a single module meets the oxygen demand of the emergency rescue standard; the oxygen supply terminal module 4 comprises a proportional valve, an integrated oxygen outlet and the like, and provides the user with oxygen supply modes such as diffuse oxygen supply and nasal suction oxygen supply; the off-vehicle environment sensing module 5 can continuously monitor the off-vehicle temperature and humidity, altitude, off-vehicle atmospheric pressure, off-vehicle air quality and the like; the in-vehicle environment sensing module 6 can continuously monitor the in-vehicle oxygen concentration, the in-vehicle carbon dioxide concentration, the oxygen supply concentration and the oxygen supply flow rate of the oxygen generating device (i.e. the vehicle-mounted oxygen generating device 2 and / or the emergency oxygen generating device 3) and the like.

[0039] The off-vehicle environment sensing module 5 and the in-vehicle environment sensing module 6 each upload the collected sensor data to the electronic control unit 1, and the electronic control unit 1 calculates the in-vehicle user oxygen demand and starts the corresponding oxygen generating device to generate oxygen by using a multi-modal fusion algorithm. Specifically, the electronic control unit 1 can judge the oxygen demand by using a multi-sensor fusion algorithm (i.e. the multi-modal fusion algorithm at this time) and then send corresponding ECU instructions to the corresponding actuators (such as the vehicle-mounted oxygen generating device 2, the emergency oxygen generating device 3 and the oxygen supply terminal module 4) to intelligently switch the vehicle-mounted oxygen generating device 2 and the emergency oxygen generating device 3, and start different functions to meet the oxygen demand in different scenarios through the ECU instructions.

[0040] Referring to Figure 2 and Figure 3 As shown, the oxygen supply strategy of the vehicle-mounted oxygen supply system is as follows: Step 201, the user starts the vehicle-mounted oxygen supply system in the vehicle.

[0041] When the user starts the vehicle-mounted oxygen supply system in the vehicle, the vehicle sensing module (i.e. the off-vehicle environment sensing module 5 and the in-vehicle environment sensing module 6) monitors the in-vehicle and off-vehicle environment, collects the in-vehicle and off-vehicle environment information, and uploads the in-vehicle and off-vehicle environment information to the electronic control unit 1; Step 202, the system normally starts to use the vehicle-mounted oxygen generating device 2.

[0042] The vehicle exterior environment perception module 5 monitors that the vehicle is in a low altitude area, at this time the oxygen concentration in the low altitude area is relatively sufficient, and the health care is mainly used, and the personnel will not be oxygen deficient, but the oxygen can be supplemented for health, the vehicle interior environment perception module 6 monitors the oxygen concentration in the vehicle in real time, and the oxygen supply terminal module 4 is used to supply oxygen by the on-board oxygen generation equipment 2 when oxygen is needed, so as to maintain the constant oxygen-enriched environment in the vehicle.

[0043] Step 203, when the vehicle perception module monitors that the vehicle is in an extremely high altitude, the oxygen concentration in the vehicle and the nasal breathing oxygen supply information (including the nasal breathing oxygen supply concentration and the nasal breathing oxygen supply flow) of the on-board oxygen generation equipment 2 are monitored synchronously, and whether the oxygen concentration in the vehicle or the nasal breathing oxygen supply information meets the design standard is judged according to the altitude (that is, whether the oxygen concentration in the vehicle or the nasal breathing oxygen supply information meets the standard is judged according to the altitude).

[0044] When the vehicle is moving and the vehicle perception module monitors that the vehicle is in an extremely high altitude, whether the oxygen concentration in the vehicle meets the oxygen supplement standard of the extremely high altitude or whether the oxygen supply flow and the oxygen supply concentration of the nasal breathing oxygen supply of the on-board oxygen generation equipment 2 meet the oxygen supplement standard is judged according to the altitude.

[0045] When it is monitored that the oxygen concentration in the vehicle or the nasal breathing oxygen supply information meets the standard, step 204 is executed.

[0046] Step 204, the on-board oxygen generation equipment 2 is continuously used, and the oxygen concentration in the vehicle and the nasal breathing oxygen supply information are continuously monitored.

[0047] If the oxygen concentration in the vehicle meets the set corresponding oxygen supplement standard (that is, the oxygen supplement standard of the extremely high altitude) or the oxygen supply flow and the oxygen supply concentration of the nasal breathing oxygen supply of the on-board oxygen generation equipment 2 meet the oxygen supplement standard when the vehicle is in the extremely high altitude, the oxygen concentration and the oxygen flow are continuously monitored by the vehicle sensor and the data are fed back to the electronic control unit 1.

[0048] When it is monitored that the oxygen concentration in the vehicle or the nasal breathing oxygen supply information does not meet the standard, step 205 is executed.

[0049] Step 205, the system determines the oxygen deficiency amount, and according to the oxygen deficiency amount, the emergency oxygen generation equipment 3 is started to supply oxygen to supplement the required oxygen amount.

[0050] If the oxygen concentration in the vehicle cannot (or is difficult to) meet the set corresponding oxygen supplement standard or the oxygen supply flow and the oxygen supply concentration of the nasal breathing oxygen supply of the on-board oxygen generation equipment 2 cannot (or is difficult to) meet the oxygen supplement standard when the vehicle is in the extremely high altitude, the oxygen concentration and the oxygen flow monitored and fed back by the vehicle sensor are compared with the set corresponding oxygen supplement standard, the current oxygen requirement amount is calculated, and one or more modules of the emergency oxygen generation equipment 3 are called according to the current oxygen requirement amount as a supplement of the on-board oxygen generation equipment 2 and supply oxygen together with the on-board oxygen generation equipment 2 to meet the oxygen requirement demand when the vehicle is in the extremely high altitude.

[0051] The emergency oxygen generating device 3 is composed of multiple modules. The emergency oxygen generating device 3 can be used by a single module or multiple modules in series / parallel.

[0052] Generally, the vehicle-mounted oxygen generating device 2 does not have the problem of insufficient oxygen supply in medium-high altitude areas, but the vehicle-mounted oxygen generating device 2 in extremely high altitude areas may have the problem of oxygen concentration decrease and insufficient oxygen supply due to atmospheric pressure change and the limitation of physical oxygen generating principle. When the vehicle-mounted oxygen generating device 2 has insufficient oxygen supply, the current oxygen demand needs to be calculated. If it is calculated that a single module of the emergency oxygen generating device 3 can meet the oxygen supplement amount (i.e. the maximum oxygen supply amount of a single module is greater than the current oxygen demand), only a single module is activated for oxygen supply. If it is calculated that a single module of the emergency oxygen generating device 3 cannot meet the oxygen supplement amount (i.e. the maximum oxygen supply amount of a single module is not greater than the current oxygen demand), it means that multiple modules need to be used for oxygen supply, so multiple modules are activated for oxygen supply at the same time. In the case where the emergency oxygen generating device 3 includes both physical oxygen generating modules and chemical oxygen generating modules, the physical oxygen generating modules are preferentially used for oxygen supply, and the chemical oxygen generating modules are used for oxygen supply when the physical oxygen generating modules cannot be used for oxygen supply.

[0053] Step 206: When the number of people in the vehicle increases, whether the in-vehicle oxygen concentration and nose-breathing oxygen supply information meet the standards is monitored.

[0054] When it is monitored that the in-vehicle oxygen concentration and nose-breathing oxygen supply information meet the standards, steps 203 and 204 are performed.

[0055] When it is monitored that the in-vehicle oxygen concentration and nose-breathing oxygen supply information do not meet the standards, step 205 is performed.

[0056] When the vehicle is in an extremely high altitude area, nose breathing is usually used to efficiently supplement a large amount of oxygen; but when external personnel who need help enter the vehicle, the number of people using oxygen in the vehicle increases, and the oxygen concentration and oxygen flow need to be judged according to the number of people using oxygen in the vehicle and the altitude area where the vehicle is located to determine whether they meet the corresponding oxygen supplement standards.

[0057] If the number of people using oxygen in the vehicle increases but still meets the set oxygen use standards, the in-vehicle sensor continuously monitors the oxygen concentration and oxygen flow and feeds back the data to the electronic control unit 1 in real time.

[0058] In the case where the vehicle encounters extremely harsh working conditions (such as vehicle power failure), the vehicle-mounted oxygen generating device 2 cannot be used. At this time, if the user in the vehicle still needs to inhale oxygen, the emergency oxygen generating device 3 can be manually activated. The emergency oxygen generating device 3 can be used to diffuse oxygen through the vehicle pipeline, or the nose suction tube / oxygen mask can be directly connected to the emergency oxygen generating device 3 for oxygen inhalation.

[0059] In addition, when outdoor activities, operations or rescues are carried out in high-altitude / ultra-high-altitude areas, the emergency oxygen generating device 3 can be carried as a mobile oxygen source, and the number of carried modules can be selected according to the use.
