However, the existing system faces technical challenges in vibration and energy consumption management during vehicle driving. The vibration not only affects the oxygen generation efficiency, but also may shorten the service life of the oxygen generation equipment.

[0003] Therefore, how to realize the collaborative control of active vibration reduction and oxygen generation in the vehicle-mounted oxygen generation system to improve the stability and oxygen supply efficiency of the oxygen generation equipment, and optimize the energy consumption management is a technical problem to be solved at present.

[0005] In order to achieve the above purpose, the main technical scheme adopted by the present application includes: In a first aspect, the present application provides a vehicle-mounted oxygen generation system active vibration reduction and oxygen generation collaborative control method, the vehicle-mounted oxygen generation system comprising an oxygen generation equipment, the method comprising: real-time acquisition of the current altitude of the vehicle; determination of an oxygen supply amount adapted to the current altitude; determination of a vibration influence factor of the oxygen generation equipment based on the oxygen supply amount; determination of an active compensation force of the oxygen generation equipment according to the vibration influence factor, so as to perform active vibration reduction through the active compensation force.

[0006] The vehicle-mounted oxygen generation system active vibration reduction and oxygen generation collaborative control method provided by the present embodiment can determine the oxygen supply amount adapted to the altitude by real-time acquisition of the current altitude of the vehicle, so as to meet the physiological needs of passengers under different environmental conditions. Based on this oxygen supply amount, the system further calculates the vibration influence factor of the oxygen generation equipment to evaluate the running state of the equipment. Then, according to the vibration influence factor, the system determines the required active compensation force to realize active vibration reduction. This process enables the vehicle-mounted oxygen generation system to maintain equipment stability, improve oxygen supply efficiency, and optimize energy consumption management in complex environments, thereby providing users with a more comfortable and safe driving experience.

[0007] In one embodiment, the determining the oxygen supply amount adapted to the current altitude comprises: obtaining a target altitude input by a user; determining a current altitude difference according to a difference between the target altitude and the current altitude; determining an oxygen supply proportion increment matched with the current altitude difference; superimposing the oxygen supply proportion increment on a reference oxygen supply amount to obtain the oxygen supply amount.

[0008] The embodiment determines the current altitude difference by comparing the target altitude input by the user with the current altitude in real time. The dynamic feedback mechanism enables the system to quickly respond to environmental changes and adjust the oxygen supply amount accordingly. Next, by calculating the oxygen supply proportion increment matched with the altitude difference, the system precisely controls the delivery of oxygen to ensure the provision of appropriate oxygen concentration under different altitude conditions. In addition, superimposing the oxygen supply proportion increment on the reference oxygen supply amount, the final oxygen supply amount not only improves the comfort of the occupants, but also reduces energy consumption, achieving higher economy.

[0009] In one embodiment, the determining the vibration influence factor of the oxygen generating device based on the oxygen supply amount comprises: obtaining an oxygen supply threshold set for the oxygen generating device; determining a ratio between the oxygen supply amount and the oxygen supply threshold; determining the ratio as the vibration influence factor.

The amplitude control quantity is determined based on the vibration influence factor and the real-time vibration amplitude, so that the system can flexibly adjust the active compensation force under different vibration conditions to minimize the interference with the oxygen generating equipment. In this process, the calculation of the active compensation force further enhances the stability of the oxygen generating equipment, effectively reduces the vibration influence by actively applying an active compensation force in the opposite direction, and keeps the oxygen generating equipment in the best working state, thereby improving the oxygen supply efficiency. Therefore, the vehicle-mounted oxygen generating system realizes collaborative control of active vibration reduction and oxygen generation, improves the overall performance, and provides users with a more comfortable and efficient driving experience.

[0013] In one embodiment, the method further comprises: real-time acquisition of the current battery power of the vehicle; determining the oxygen generating power of the oxygen generating equipment according to the comparison result between the current battery power and the preset power threshold.

[0014] The embodiment realizes real-time acquisition of the current battery power of the vehicle to ensure that the system can accurately monitor the power supply state. The oxygen generating power of the oxygen generating equipment is dynamically adjusted according to the comparison result between the current battery power and the preset power threshold. This real-time monitoring and intelligent adjustment mechanism enables the system to flexibly respond under different power levels, ensuring maximum oxygen generating capacity when the power is sufficient to meet user needs, and reducing the oxygen generating power when the power is low to effectively protect the battery, prolong its service life, and optimize energy consumption management. This series of measures not only improves the stability of the oxygen generating system, but also ensures efficient use of energy, thereby improving the overall user experience.

[0015] In one embodiment, the determination of the oxygen generating power of the oxygen generating equipment according to the comparison result between the current battery power and the preset power threshold comprises: if the current battery power is less than or equal to the preset first power threshold, the oxygen generating power is determined to be zero; if the current battery power is greater than the preset first power threshold and less than or equal to the preset second power threshold, the oxygen generating power is determined based on the preset power threshold, the current battery power, and the rated power of the oxygen generating equipment; if the current battery power is greater than the preset second power threshold, the rated power is determined as the oxygen generating power.

[0016] The embodiment sets the oxygen production power to zero when the current battery power is lower than the preset first threshold value, to prevent over-discharge of the battery and protect the health of the battery; when the battery power is between the preset first threshold value and the preset second threshold value, the system dynamically calculates the oxygen production power according to the real-time power, to reasonably allocate energy and reduce unnecessary waste; when the battery power is higher than the preset second threshold value, the system can provide the rated power at full capacity, to fully utilize the remaining power. The cooperative control of active vibration reduction and oxygen production not only ensures stable operation of the system under different working conditions, but also optimizes energy consumption management and improves overall work efficiency, to provide users with a safer and more comfortable use experience.

[0018] The vehicle-mounted oxygen production system of the embodiment integrates key components such as an oil-free air compressor, an oxygen production device, an air compressor suction and discharge pipe, an air inlet filter, and an oxygen supply pipe, aiming to achieve efficient air treatment and stable oxygen supply. The oil-free air compressor sucks clean air through the air inlet filter and sends the compressed air into the oxygen production device through the air compressor suction and discharge pipe, ensuring the continuity and stability of air input. This design provides protection for the normal operation of the oxygen production device, allowing it to effectively separate oxygen and nitrogen using the vacuum pressure swing adsorption process (VPSA), so that oxygen can be flexibly supplied to users inside the vehicle through the oxygen supply pipe. At the same time, nitrogen is returned to the oil-free air compressor through the air compressor suction and discharge pipe and discharged through the nitrogen discharge silencer, which helps to optimize energy consumption management.

DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0026] With the improvement of people's requirements for health and quality of life, vehicle-mounted oxygen production systems have gradually become important equipment in scenarios such as highlands, long-distance travel, and special groups (such as patients with respiratory system diseases). These systems can effectively supplement oxygen inside the vehicle, improving the comfort and safety of passengers. However, existing vehicle-mounted oxygen production systems still face some technical challenges in practical application, especially in terms of vibration and energy consumption management.

[0027] During vehicle driving, vehicle-mounted devices are often affected by vibration due to factors such as road conditions and speed fluctuations. This vibration not only affects the working efficiency of the oxygen production equipment, but also can cause the service life of the equipment to be shortened.

[0028] Therefore, how to realize the collaborative control of active vibration reduction and oxygen production in a vehicle-mounted oxygen production system to improve the stability and oxygen supply efficiency of the oxygen production equipment, while optimizing energy consumption management is a technical problem that needs to be solved at present.

[0029] According to the embodiments of the present application, a vehicle-mounted oxygen production system active vibration reduction and oxygen production collaborative control method embodiment is provided. It should be noted that the steps shown in the flowchart of the drawings can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from here.

[0030] In this embodiment, a vehicle-mounted oxygen production system active vibration reduction and oxygen production collaborative control method is provided, Figure 1 A flowchart of a vehicle-mounted oxygen production system active vibration reduction and oxygen production collaborative control method provided by the embodiments of the present application is shown in FIG. 1. The vehicle-mounted oxygen production system includes an oxygen production equipment, such as Figure 1 As shown in the figure, the flow includes the following steps: Step S1, the current altitude of the vehicle is obtained in real time.

[0031] Specifically, through satellite signals, GPS can provide the precise position of the vehicle, including the current altitude.

[0032] Step S3, determine the oxygen supply amount adapted to the current altitude.

[0033] Specifically, the target altitude is obtained through the user interface and compared with the current altitude to determine the current altitude difference. The system can respond to environmental changes in real time and accurately calculate the oxygen supply ratio increment needed to increase, thereby effectively compensating for the oxygen thinning phenomenon caused by altitude increase. Specifically, by calculating the oxygen supply ratio increment and the final oxygen supply amount, it ensures that passengers can obtain appropriate oxygen concentration under different altitude conditions, which not only improves passenger comfort, but also optimizes energy consumption, enhances the economy and efficiency of the system.

[0034] Step S5, determine the vibration influence factor of the oxygen generating device based on the oxygen supply amount.

[0035] Specifically, by extracting the oxygen supply threshold set by the oxygen generating device, the ratio between the current oxygen supply amount and the threshold is calculated to obtain the vibration influence factor. This ratio serves as a key indicator, reflecting the operating state of the oxygen supply amount relative to the design limit of the device. By analyzing the vibration influence factor, the system can assess the potential impact of the oxygen supply amount on the vibration of the oxygen generating device, ensuring its efficient operation and reducing the failure rate.

[0036] Step S7, determine the active compensation force of the oxygen generating device according to the vibration influence factor, to actively dampen through the active compensation force.

[0037] Specifically, by monitoring the vibration amplitude and angular frequency of the vehicle in real time, the system ensures accurate understanding of the dynamic state of the vehicle. Based on the vibration influence factor and the obtained vibration amplitude, the system calculates the amplitude control amount, thereby flexibly adjusting the active compensation force to offset the impact of vibration on the oxygen generating device. When the oxygen supply amount increases and the vibration influence factor exceeds the threshold, the amplitude control amount is enhanced, improving the active damping capacity of the device; while the oxygen supply amount decreases, the amplitude control amount is reduced to avoid excessive energy consumption and maintain system stability. By applying an active compensation force in the opposite direction, the vibration impact is effectively reduced, keeping the oxygen generating device in an optimal working state. This active damping and oxygen generation synergistic control significantly improves the overall performance of the system, providing users with a more comfortable and efficient driving experience.

[0038] The embodiment provides a vehicle-mounted oxygen generation system active vibration reduction and oxygen generation collaborative control method, which acquires the current altitude of a vehicle in real time, so that the system can determine the oxygen supply amount suitable for the altitude, thereby meeting the physiological needs of passengers under different environmental conditions. Based on the oxygen supply amount, the system further calculates the vibration influence factor of the oxygen generation device to evaluate the operation state of the device. Subsequently, according to the vibration influence factor, the system determines the required active compensation force to realize active vibration reduction. This process enables the vehicle-mounted oxygen generation system to maintain the stability of the device under complex environments, improve the oxygen supply efficiency, and optimize energy consumption management, thereby providing users with a more comfortable and safe driving experience.

[0039] Figure 2 The flowchart of step S3 provided by the embodiment of the present application can include the following steps: Step S31, acquiring the target altitude input by a user.

[0040] Specifically, the target altitude is the altitude defined by the user that they hope to reach. The target altitude is received through a user interface (such as a touch screen, button, or voice input).

[0041] Step S33, determining the current altitude difference according to the difference between the target altitude and the current altitude.

[0042] Specifically, the difference between the target altitude and the current altitude is calculated to evaluate the increased oxygen supply amount, and the specific formula is: ΔH = H target -H current , where ΔH is the current altitude difference, H target is the target altitude, and H current is the current altitude.

[0043] Step S35, determining the oxygen supply proportion increment matched with the current altitude difference.

[0044] Specifically, the proportion of oxygen supply is adjusted according to the altitude difference to compensate for the oxygen thinning phenomenon caused by the increase in altitude. According to a pre-set model, the oxygen supply proportion increment O increment corresponding to the current altitude difference is calculated, and the specific formula is: O increment =k×△H, where k is a proportion coefficient obtained according to experimental data, representing the influence degree of altitude change on oxygen supply.

[0045] Step S37, superimposing the oxygen supply proportion increment and the reference oxygen supply amount to obtain the oxygen supply amount.

[0046] Specifically, the reference oxygen supply amount and the oxygen supply proportion increment are combined to obtain the final oxygen supply amount O output, ensuring that the user experiences sufficient oxygen at the target altitude, with the specific formula being: O output =O base ×O increment , where O base is the baseline oxygen supply. The baseline oxygen supply refers to the basic oxygen supply required by the human body under standard atmospheric conditions, obtained based on experimental data.

[0047] This embodiment determines the current altitude difference by comparing the target altitude input by the user with the current altitude in real time. This dynamic feedback mechanism enables the system to quickly respond to environmental changes and adjust the oxygen supply accordingly. Next, by calculating the oxygen supply proportion increment matched with the altitude difference, the system precisely controls the delivery of oxygen, ensuring appropriate oxygen concentration under different altitude conditions. Additionally, superimposing the oxygen supply proportion increment with the baseline oxygen supply, the final oxygen supply not only improves the comfort of the occupants but also reduces energy consumption, achieving higher economic efficiency.

[0048] Figure 3 The flowchart of step S5 provided by the embodiment of the present application can include the following steps: Step S51, obtain the oxygen supply threshold set by the oxygen production equipment.

[0049] Specifically, the set oxygen supply threshold is extracted from the oxygen production equipment. This threshold is determined by the design of the oxygen production equipment and is usually based on the working principle and performance limitations of the oxygen production equipment. The oxygen supply threshold O threshold is defined as the maximum oxygen supply that the oxygen production equipment can provide under normal operating conditions, in units of liters per minute.

[0050] Step S53, determine the ratio between the oxygen supply and the oxygen supply threshold.

[0051] Specifically, the ratio reflects the proportion of the current oxygen supply relative to the design limit of the oxygen production equipment. If the ratio is greater than 1, it means that the oxygen supply exceeds the oxygen supply threshold, which may cause the equipment to run overload or fail; if the ratio is less than 1, it indicates that the oxygen production equipment is running within a safe range. This ratio is a key indicator for evaluating system performance and safety, with the specific formula being: V impact =O output / O threshold .

[0052] Step S55, determine the ratio as the vibration influence factor.

[0053] Specifically, the ratio V impactThe vibration impact factor is determined. The vibration impact factor provides a quantitative indicator for the system, helping to assess the potential impact of the current oxygen supply on the vibration of the oxygen production equipment. When the oxygen supply is too high, the oxygen production equipment may generate more vibration due to excessive load, which not only affects the stability of the oxygen production equipment, but also may lead to a higher failure rate. Therefore, monitoring the vibration impact factor is crucial for maintaining the long-term health of the oxygen production equipment.

[0054] The embodiment calculates the ratio between the oxygen supply and the oxygen supply threshold, which provides real-time feedback to the system. The ratio is determined as the vibration impact factor, allowing the system to analyze the impact of vibration on the performance of the oxygen production equipment.

[0055] Figure 4 The flowchart of step S7 provided by the embodiment of the present application can include the following steps: Step S71, real-time acquisition of the vibration amplitude and angular frequency of the vehicle.

[0056] Specifically, the vibration of the vehicle during operation is monitored. The vibration amplitude reflects the intensity of external impact on the vehicle, while the angular frequency indicates the periodic characteristics of the vibration. Through real-time data acquisition, the system can obtain accurate vibration amplitude and angular frequency.

[0057] Step S73, determining the amplitude control quantity based on the vibration impact factor and the vibration amplitude.

[0058] Specifically, based on the vibration impact factor and the vibration amplitude, the system calculates the amplitude control quantity: D×A×V impact , where D is the gain coefficient of the electromagnetic / piezoelectric actuator, N•m -1 ; A is the vibration amplitude reference (given by the acceleration or displacement sensor), m or m•s -2 .

[0059] Step S75, determining the active compensation force for counteracting vibration according to the amplitude control quantity and the angular frequency.

[0060] Specifically, according to the amplitude control quantity and the angular frequency, the system calculates the active compensation force for counteracting vibration, F compensation (t)=-sin(ωt)×D×A×V impact , where F compensation (t) is the active compensation force, ω is the angular frequency, rad•s -1 .

[0061] When O output increases, V impact >1, the amplitude control quantity increases synchronously, and the active vibration reduction capability of the oxygen production equipment is enhanced; when Ooutput decrease, V impact <1, the amplitude control quantity is synchronously reduced, avoiding excessive energy consumption when oxygen is insufficient, while ensuring system stability; The negative sign in the formula indicates that the application direction of the active compensation force is opposite to the vibration direction (180° phase difference), realizing active damping.

[0062] In this embodiment, the vibration amplitude and angular frequency of the vehicle are obtained in real time, and the system can timely monitor the vehicle dynamics to ensure accurate understanding of the vibration state. Based on the vibration influence factor and the real-time vibration amplitude, the amplitude control quantity is determined, so that the system can flexibly adjust the active compensation force under different vibration conditions to minimize the interference to the oxygen generating equipment. In this process, the calculation of the active compensation force further enhances the stability of the oxygen generating equipment. By actively applying an active compensation force in the opposite direction, the vibration influence is effectively reduced, and the oxygen generating equipment is kept in the best working state, thereby improving the oxygen supply efficiency. Therefore, the vehicle-mounted oxygen generating system realizes the cooperative control of active vibration reduction and oxygen generation, improves the overall performance, and provides users with a more comfortable and efficient driving experience.

[0063] Figure 5 The flowchart provided by the embodiment of the present application for determining the oxygen generating power of the oxygen generating equipment can include the following steps: Step S2, the current battery power of the vehicle is obtained in real time.

[0064] Step S4, the oxygen generating power of the oxygen generating equipment is determined according to the comparison result between the current battery power and the preset power threshold.

[0065] In this embodiment, the current battery power of the vehicle is obtained in real time to ensure that the system can accurately monitor the power supply state. According to the comparison result between the current battery power and the preset power threshold, the oxygen generating power of the oxygen generating equipment is dynamically adjusted. This real-time monitoring and intelligent adjustment mechanism enables the system to flexibly respond under different power levels, ensuring maximum oxygen generating capacity when the power is sufficient to meet user demand, and correspondingly reducing the oxygen generating power when the power is low, thereby effectively protecting the battery, prolonging its service life, and optimizing energy consumption management. This series of measures not only improves the stability of the oxygen generating system, but also ensures efficient use of energy, thereby improving the overall user experience.

[0066] Figure 6 The flowchart of step S4 provided by the embodiment of the present application can include the following steps: Step S41, if the current battery power is less than or equal to the preset first power threshold, the oxygen generating power is determined to be zero.

[0067] Specifically, when the current battery power E current is less than or equal to the preset first power threshold Elow , the system sets the oxygen production power P O to zero. This measure aims to protect the battery from damage caused by deep discharge and ensure that the vehicle maintains basic functions and safety in a low battery state.

[0068] In step S43, if the current battery level is greater than the preset first battery level threshold and less than or equal to the preset second battery level threshold, the oxygen production power is determined based on the preset battery level threshold, the current battery level, and the rated power of the oxygen production device.

[0069] Specifically, when the current battery level E current is between the preset first battery level threshold E low and the preset second battery level threshold E high , the system dynamically calculates the oxygen production power according to the current battery level, the preset battery level threshold, and the rated power P max of the oxygen production device. The oxygen production power at this time can be determined by the following formula: P O =P max (1-E low / E current ). This ensures that the oxygen production power gradually decreases when the battery level is insufficient, extending the battery usage time while providing necessary oxygen production capacity within a certain range.

[0070] In step S45, if the current battery level is greater than the preset second battery level threshold, the rated power is determined as the oxygen production power.

[0071] Specifically, when the current battery level is greater than the preset second battery level threshold E high , the system determines the oxygen production power as the rated power P max . At this time, the system can fully utilize the remaining battery power, improve oxygen production efficiency, and meet higher oxygen demand.

[0072] This embodiment sets the oxygen production power to zero when the current battery level is lower than the preset first threshold to prevent battery over-discharge and protect its health. When the battery level is between the preset first threshold and the preset second threshold, the system dynamically calculates the oxygen production power according to the real-time battery level, thereby reasonably allocating energy and reducing unnecessary waste. When the battery level is higher than the preset second threshold, the system can provide the rated power at full capacity, fully utilizing the remaining battery power. This active damping and oxygen production coordination control not only ensures stable operation of the system under different working conditions, but also optimizes energy consumption management, improves overall work efficiency, and provides users with a safer and more comfortable user experience.

[0074] Specifically, the oil-free air compressor 1 is a four-cylinder oil-free air compressor. It sucks in air through the air inlet filter 4. While two cylinders are compressing, the other two cylinders are sucking in air. This design ensures the continuity and stability of air input. The compressed air is cooled by the radiator and fan, and then delivered to the oxygen generation device 2 through the air compressor suction and exhaust pipe 3.

Nitrogen is discharged through the nitrogen discharge silencer 6.

[0075] The vehicle-mounted oxygen generation system of the embodiment integrates key components such as the oil-free air compressor 1, the oxygen generation device 2, the air compressor suction and exhaust pipe 3, the air inlet filter 4, and the oxygen supply pipe 5, aiming to achieve efficient air processing and stable oxygen supply. The oil-free air compressor 1 sucks in clean air through the air inlet filter 4, compresses it, and then sends it to the oxygen generation device 2 through the air compressor suction and exhaust pipe 3, ensuring the continuity and stability of air input. This design provides protection for the normal operation of the oxygen generation device 2, allowing it to effectively separate oxygen and nitrogen using the vacuum pressure swing adsorption process (VPSA), so that oxygen can be flexibly supplied to users inside the vehicle through the oxygen supply pipe 5. At the same time, nitrogen is returned to the oil-free air compressor 1 through the air compressor suction and exhaust pipe 3 and discharged through the nitrogen discharge silencer 6, which helps to optimize energy consumption management.
