[0001] This application relates to the field of vehicle technology, and in particular to a method and device for active vibration reduction and coordinated oxygen production control of an on-board oxygen generation system. Background Technology

[0002] As people's demands for health and quality of life increase, in-vehicle oxygen generation systems are gradually becoming important equipment in high-altitude areas, long-distance travel, and for specific groups of people. They can effectively replenish the oxygen inside the vehicle and improve passenger comfort and safety. However, existing systems face technical challenges in application, such as vibration and energy consumption management. Vibration during vehicle operation not only affects oxygen generation efficiency but may also shorten the lifespan of the oxygen generation equipment.

[0003] Therefore, how to achieve coordinated control of active vibration reduction and oxygen production in vehicle-mounted oxygen production systems to improve the stability of oxygen production equipment and oxygen supply efficiency, while optimizing energy consumption management, is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides a method and device for coordinated control of active vibration reduction and oxygen production in a vehicle-mounted oxygen production system. This method achieves coordinated control of active vibration reduction and oxygen production in the vehicle-mounted oxygen production system, thereby improving the stability of the oxygen production equipment and the oxygen supply efficiency, while also optimizing energy consumption management.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] In a first aspect, embodiments of this application provide a method for coordinated control of active vibration reduction and oxygen generation in a vehicle-mounted oxygen generation system, wherein the vehicle-mounted oxygen generation system includes an oxygen generation device, and the method includes:

[0007] Real-time acquisition of the vehicle's current altitude;

[0008] Determine the appropriate oxygen supply for the current altitude;

[0009] The vibration impact factor of the oxygen generating equipment is determined based on the oxygen supply volume.

[0010] Based on the vibration influence factor, the active compensation force of the oxygen generating equipment is determined so as to actively reduce vibration through the active compensation force.

[0011] This embodiment provides a method for active vibration reduction and coordinated oxygen production control of an on-board oxygen generation system. By acquiring the vehicle's current altitude in real time, the system can determine the appropriate oxygen supply for that altitude, thereby meeting the physiological needs of occupants under different environmental conditions. Based on this oxygen supply, the system further calculates the vibration impact factor of the oxygen generation equipment to assess its operating status. Subsequently, based on this vibration impact factor, the system determines the required active compensation force to achieve active vibration reduction. This process enables the on-board oxygen generation system to maintain equipment stability in complex environments, improve oxygen supply efficiency, and optimize energy consumption management, thus providing users with a more comfortable and safer driving experience.

[0012] In one implementation, determining the oxygen supply appropriate for the current altitude includes:

[0013] Get the target altitude input by the user;

[0014] The current altitude difference is determined based on the difference between the target altitude and the current altitude.

[0015] Determine the oxygen supply ratio increment that matches the current altitude difference;

[0016] The oxygen supply ratio increment is added to the baseline oxygen supply to obtain the oxygen supply amount.

[0017] In this embodiment, the system obtains the target altitude input by the user in real time and compares it with the current altitude to determine the current altitude difference. 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 ratio increment matched to the altitude difference, the system precisely controls oxygen delivery to ensure an appropriate oxygen concentration under different altitude conditions. Furthermore, by superimposing the oxygen supply ratio increment with the baseline oxygen supply, the final oxygen supply not only improves passenger comfort but also reduces energy consumption, achieving greater economic efficiency.

[0018] In one embodiment, determining the vibration impact factor of the oxygen generating equipment based on the oxygen supply includes:

[0019] Obtain the oxygen supply threshold set by the oxygen generator;

[0020] Determine the ratio between the oxygen supply amount and the oxygen supply threshold;

[0021] The ratio is determined as the vibration influence factor.

[0022] This embodiment obtains a set oxygen supply threshold and calculates the ratio between the oxygen supply amount and the oxygen supply threshold. This ratio provides real-time feedback to the system. The ratio is determined as the vibration impact factor, enabling the system to analyze the impact of vibration on the performance of the oxygen generating equipment.

[0023] In one embodiment, determining the active compensation force of the oxygen generating equipment based on the vibration influence factor includes:

[0024] The vibration amplitude and angular frequency of the vehicle are acquired in real time.

[0025] Based on the vibration influence factor and the vibration amplitude, determine the amplitude control value;

[0026] Based on the amplitude control value and the angular frequency, an active compensation force is determined to counteract the vibration.

[0027] This embodiment acquires the vehicle's vibration amplitude and angular frequency in real time, enabling the system to monitor vehicle dynamics promptly and ensure an accurate understanding of the vibration status. Based on the vibration influence factor and real-time vibration amplitude, the system determines the amplitude control value, allowing for flexible adjustment of the active compensation force under different vibration conditions to minimize interference with the oxygen generator. During this process, the calculation of the active compensation force further enhances the stability of the oxygen generator. By actively applying an active compensation force in the opposite direction, the impact of vibration is effectively mitigated, and the oxygen generator is kept in optimal operating condition, thereby improving oxygen supply efficiency. Therefore, the onboard oxygen generator system achieves coordinated control of active vibration reduction and oxygen generation, improving overall performance and providing users with a more comfortable and efficient driving experience.

[0028] In one embodiment, the method further includes:

[0029] Get the vehicle's current battery level in real time;

[0030] The oxygen production power of the oxygen generator is determined based on the comparison between the current battery level and the preset battery level threshold.

[0031] This embodiment acquires the vehicle's current battery level in real time to ensure accurate monitoring of the power status. Based on a comparison between the current battery level and a preset power threshold, the oxygen generator's output power is dynamically adjusted. This real-time monitoring and intelligent adjustment mechanism allows the system to flexibly respond to different battery levels, ensuring maximum oxygen production capacity when the battery is fully charged to meet user needs; while reducing output power when the battery is low, effectively protecting the battery, extending its lifespan, and optimizing energy management. These measures not only improve the stability of the oxygen generator system but also ensure efficient energy utilization, thereby enhancing the overall user experience.

[0032] In one embodiment, determining the oxygen production power of the oxygen generator based on a comparison between the current battery level and a preset battery level threshold includes:

[0033] If the current battery level is less than or equal to the preset first battery level threshold, then the oxygen production power is determined to be zero.

[0034] If the current battery power is greater than the preset first power threshold, and the current battery power is less than or equal to the preset second power threshold, then the oxygen production power is determined based on the preset power threshold, the current battery power, and the rated power of the oxygen generator.

[0035] If the current battery charge is greater than the preset second charge threshold, then the rated power is determined as the oxygen production power.

[0036] This embodiment sets the oxygen production power to zero when the current battery level is below a preset first threshold to prevent over-discharge and protect the battery's health. When the battery level is between the preset first and second thresholds, the system dynamically calculates the oxygen production power based on the real-time battery level, thereby rationally allocating energy and reducing unnecessary waste. When the battery level is above the preset second threshold, the system can provide full rated power to make full use of the remaining electrical energy. This coordinated control of active vibration reduction and oxygen production not only ensures the stable operation of the system under different operating conditions but also optimizes energy consumption management, improves overall work efficiency, and provides users with a safer and more comfortable user experience.

[0037] In one embodiment, the vehicle-mounted oxygen generation system further includes an oil-free air compressor, an air compressor suction and discharge pipe, an intake filter, and an oxygen supply pipe;

[0038] The oil-free air compressor and the oxygen generator are connected through the air compressor's suction and discharge pipes. The oil-free air compressor is used to draw in air through the air intake filter and compress the air to send it into the oxygen generator through the air compressor's suction and discharge pipes.

[0039] The outlet of the oxygen generator is connected to the oxygen supply pipe. The oxygen generator is used to receive the air and adsorb and desorb the air to obtain oxygen and nitrogen. The oxygen is supplied to the vehicle interior through the oxygen supply pipe, and the nitrogen is output to the oil-free air compressor through the air compressor suction and discharge pipe and discharged through the nitrogen exhaust silencer connected to the oil-free air compressor.

[0040] This embodiment of the vehicle-mounted oxygen generation system integrates key components such as an oil-free air compressor, oxygen generator, air compressor intake and exhaust pipes, intake filter, and oxygen supply pipes, aiming to achieve efficient air handling and a stable oxygen supply. The oil-free air compressor draws in clean air through the intake filter, compresses it, and delivers it to the oxygen generator through the intake and exhaust pipes, ensuring a continuous and stable air input. This design guarantees the normal operation of the oxygen generator, allowing it to effectively separate oxygen and nitrogen using vacuum pressure swing adsorption (VPSA) technology, thus flexibly supplying oxygen to users inside the vehicle through the oxygen supply pipes. Simultaneously, nitrogen returns to the oil-free air compressor through the intake and exhaust pipes and is discharged through a nitrogen exhaust silencer, contributing to optimized energy management.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] As people's demands for health and quality of life increase, in-vehicle oxygen generation systems are gradually becoming important equipment in scenarios such as high altitudes, long-distance travel, and for special groups (such as patients with respiratory diseases). These systems can effectively replenish the oxygen inside the vehicle, improving passenger comfort and safety. However, existing in-vehicle oxygen generation systems still face some technical challenges in practical applications, especially in terms of vibration and energy consumption management.

[0063] During vehicle operation, onboard equipment is often subjected to vibrations due to changes in road conditions and speed fluctuations. This vibration not only affects the working efficiency of the oxygen generator but may also shorten its lifespan.

[0064] Therefore, how to achieve coordinated control of active vibration reduction and oxygen production in vehicle-mounted oxygen production systems to improve the stability of oxygen production equipment and oxygen supply efficiency, while optimizing energy consumption management, is a technical problem that urgently needs to be solved.

[0065] According to an embodiment of this application, an embodiment of an active vibration reduction and oxygen production coordinated control method for an on-board oxygen production system is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0066] This embodiment provides a method for coordinated control of active vibration reduction and oxygen production in a vehicle-mounted oxygen generation system. Figure 1 This is a flowchart illustrating a method for coordinated control of active vibration reduction and oxygen generation in an on-board oxygen generation system, as provided in this application embodiment. The on-board oxygen generation system includes an oxygen generation device, such as... Figure 1 As shown, the process includes the following steps:

[0067] Step S1: Obtain the current altitude of the vehicle in real time.

[0068] Specifically, GPS can provide a vehicle's precise location, including its current altitude, via satellite signals.

[0069] Step S3: Determine the oxygen supply appropriate for the current altitude.

[0070] Specifically, the target altitude is obtained through the user interface and compared with the current altitude to determine the current altitude difference. It can respond to environmental changes in real time, accurately calculating the required increase in oxygen supply ratio, thereby effectively compensating for oxygen depletion caused by altitude increase. Specifically, by calculating the oxygen supply ratio increment and the final oxygen supply amount, it ensures that occupants receive a suitable oxygen concentration under different altitude conditions. This not only improves passenger comfort but also optimizes energy consumption, enhancing the system's economy and efficiency.

[0071] Step S5: Determine the vibration impact factor of the oxygen generating equipment based on the oxygen supply.

[0072] Specifically, by extracting the oxygen supply threshold set by the oxygen generator, the ratio between the current oxygen supply and that threshold is calculated to obtain the vibration impact factor. This ratio, as a key indicator, reflects the operating state of the oxygen supply relative to the equipment's design limits. By analyzing the vibration impact factor, the system can assess the potential impact of the oxygen supply on the vibration of the oxygen generator, ensuring its efficient operation and reducing the failure rate.

[0073] Step S7: Determine the active compensation force of the oxygen generating equipment based on the vibration influence factor, so as to actively reduce vibration through the active compensation force.

[0074] Specifically, by monitoring the vehicle's vibration amplitude and angular frequency in real time, the system ensures an accurate understanding of the vehicle's dynamic state. Based on the vibration impact factor and the acquired vibration amplitude, the system calculates an amplitude control value, thereby flexibly adjusting the active compensation force to counteract the impact of vibration on the oxygen generator. When the oxygen supply increases and the vibration impact factor exceeds a threshold, the amplitude control value is increased, enhancing the equipment's active vibration damping capability; conversely, when the oxygen supply decreases, the amplitude control value is decreased to avoid excessive energy consumption and maintain system stability. By applying active compensation forces in opposite directions, the impact of vibration is effectively mitigated, keeping the oxygen generator in optimal operating condition. This synergistic control of active vibration damping and oxygen generation significantly improves the overall system performance, providing users with a more comfortable and efficient driving experience.

[0075] This embodiment provides a method for active vibration reduction and coordinated oxygen production control of an on-board oxygen generation system. By acquiring the vehicle's current altitude in real time, the system can determine the appropriate oxygen supply for that altitude, thereby meeting the physiological needs of occupants under different environmental conditions. Based on this oxygen supply, the system further calculates the vibration impact factor of the oxygen generation equipment to assess its operating status. Subsequently, based on this vibration impact factor, the system determines the required active compensation force to achieve active vibration reduction. This process enables the on-board oxygen generation system to maintain equipment stability in complex environments, improve oxygen supply efficiency, and optimize energy consumption management, thus providing users with a more comfortable and safer driving experience.

[0076] Figure 2 The flowchart for step S3 provided in the embodiments of this application may include the following steps:

[0077] Step S31: Obtain the target altitude input by the user.

[0078] Specifically, the target altitude is the altitude that the user defines they wish to reach. The target altitude is received through a user interface such as a touchscreen, button, or voice input.

[0079] Step S33: Determine the current altitude difference based on the difference between the target altitude and the current altitude.

[0080] Specifically, the difference between the target altitude and the current altitude is calculated to assess the required increase in oxygen supply. The specific formula is: ΔH = H target -H current Where △H is the current altitude difference, H target For the target altitude, H current This is the current altitude.

[0081] Step S35: Determine the oxygen supply ratio increment that matches the current altitude difference.

[0082] Specifically, the oxygen supply ratio is adjusted according to altitude differences to compensate for the oxygen depletion caused by increased altitude. Based on a pre-set model, the increment O of the oxygen supply ratio corresponding to the current altitude difference is calculated. increment The specific formula is: O increment =k×△H, where k is a proportionality coefficient derived from experimental data, representing the degree of influence of altitude change on oxygen supply.

[0083] Step S37: The oxygen supply ratio increment is added to the baseline oxygen supply to obtain the oxygen supply amount.

[0084] Specifically, the baseline oxygen supply is combined with the incremental increase in the oxygen supply ratio to obtain the final oxygen supply O. output To ensure users feel sufficient oxygen at the target altitude, the specific formula is: O output =O base ×O increment , of which O base The baseline oxygen supply refers to the basic amount of oxygen required by the human body under standard atmospheric conditions, derived from experimental data.

[0085] In this embodiment, the system obtains the target altitude input by the user in real time and compares it with the current altitude to determine the current altitude difference. 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 ratio increment matched to the altitude difference, the system precisely controls oxygen delivery to ensure an appropriate oxygen concentration under different altitude conditions. Furthermore, by superimposing the oxygen supply ratio increment with the baseline oxygen supply, the final oxygen supply not only improves passenger comfort but also reduces energy consumption, achieving greater economic efficiency.

[0086] Figure 3 The flowchart for step S5 provided in the embodiments of this application may include the following steps:

[0087] Step S51: Obtain the oxygen supply threshold set by the oxygen generator.

[0088] Specifically, a set oxygen supply threshold is extracted from the oxygen generator. This threshold is determined by the design of the oxygen generator, typically based on its operating principles and performance limitations. Oxygen Supply Threshold O threshold The maximum oxygen supply that an oxygen generator can provide under normal operating conditions is defined, in liters per minute.

[0089] Step S53: Determine the ratio between the oxygen supply amount and the oxygen supply threshold.

[0090] Specifically, the ratio reflects the proportion of the current oxygen supply relative to the design limit of the oxygen generator. If the ratio is greater than 1, it indicates that the oxygen supply exceeds the oxygen supply threshold, which may lead to equipment overload or malfunction; if the ratio is less than 1, it indicates that the oxygen generator is operating within a safe range. This ratio is a key indicator for evaluating system performance and safety, and the specific calculation formula is: V impact =O output / O threshold .

[0091] Step S55: Determine the ratio as the vibration influence factor.

[0092] Specifically, the ratio V impact The vibration impact factor was identified. This 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 generator. When the oxygen supply is too high, the oxygen generator may experience increased vibration due to overload, which not only affects its stability but may also lead to a higher failure rate. Therefore, monitoring the vibration impact factor is crucial for maintaining the long-term health of the oxygen generator.

[0093] This embodiment obtains a set oxygen supply threshold and calculates the ratio between the oxygen supply amount and the oxygen supply threshold. This ratio provides real-time feedback to the system. The ratio is determined as the vibration impact factor, enabling the system to analyze the impact of vibration on the performance of the oxygen generating equipment.

[0094] Figure 4 The flowchart for step S7 provided in the embodiments of this application may include the following steps:

[0095] Step S71: Real-time acquisition of vehicle vibration amplitude and angular frequency.

[0096] Specifically, the system monitors the vibration of the vehicle during operation. Vibration amplitude reflects the intensity of external impacts on the vehicle, while angular frequency indicates the periodicity of the vibration. Through real-time data acquisition, the system can obtain accurate vibration amplitude and angular frequency.

[0097] Step S73: Determine the amplitude control amount based on the vibration influence factor and vibration amplitude.

[0098] Specifically, based on the vibration influence factor and vibration amplitude, the system calculates the amplitude control quantity: D×A×V impact Where D is the gain coefficient of the electromagnetic / piezoelectric actuator, in N•m -1 A is the vibration amplitude reference (given by an acceleration or displacement sensor), in m or m•s. -2 .

[0099] Step S75: Determine the active compensation force to counteract the vibration based on the amplitude control amount and angular frequency.

[0100] Specifically, based on the amplitude control value and angular frequency, the system calculates the active compensation force F used to counteract the vibration. compensation (t)=-sin(ωt)×D×A×V impact , of which F compensation (t) represents the active compensation force, and ω represents the angular frequency in rad•s. -1 .

[0101] When O output Increase, V impact >1. The amplitude control quantity increases synchronously, and the active vibration reduction capability of the oxygen generation equipment is enhanced;

[0102] When O output Decrease, V impact <1, the amplitude control quantity is reduced synchronously to avoid excessive energy consumption when oxygen is insufficient, while ensuring system stability;

[0103] The negative sign in the formula indicates that the direction of the active compensation force is opposite to the direction of vibration (180° phase difference), thus achieving active damping.

[0104] This embodiment acquires the vehicle's vibration amplitude and angular frequency in real time, enabling the system to monitor vehicle dynamics promptly and ensure an accurate understanding of the vibration status. Based on the vibration influence factor and real-time vibration amplitude, the system determines the amplitude control value, allowing for flexible adjustment of the active compensation force under different vibration conditions to minimize interference with the oxygen generator. During this process, the calculation of the active compensation force further enhances the stability of the oxygen generator. By actively applying an active compensation force in the opposite direction, the impact of vibration is effectively mitigated, and the oxygen generator is kept in optimal operating condition, thereby improving oxygen supply efficiency. Therefore, the onboard oxygen generator system achieves coordinated control of active vibration reduction and oxygen generation, improving overall performance and providing users with a more comfortable and efficient driving experience.

[0105] Figure 5 The flowchart for determining the oxygen production power of an oxygen generator provided in this application embodiment may include the following steps:

[0106] Step S2: Obtain the vehicle's current battery level in real time.

[0107] Step S4: Determine the oxygen production power of the oxygen generator based on the comparison between the current battery power and the preset power threshold.

[0108] This embodiment acquires the vehicle's current battery level in real time to ensure accurate monitoring of the power status. Based on a comparison between the current battery level and a preset power threshold, the oxygen generator's output power is dynamically adjusted. This real-time monitoring and intelligent adjustment mechanism allows the system to flexibly respond to different battery levels, ensuring maximum oxygen production capacity when the battery is fully charged to meet user needs; while reducing output power when the battery is low, effectively protecting the battery, extending its lifespan, and optimizing energy management. These measures not only improve the stability of the oxygen generator system but also ensure efficient energy utilization, thereby enhancing the overall user experience.

[0109] Figure 6 The flowchart for step S4 provided in the embodiments of this application may include the following steps:

[0110] Step S41: If the current battery power is less than or equal to a preset first power threshold, then the oxygen production power is determined to be zero.

[0111] Specifically, when the current battery charge E current Less than or equal to the preset first power threshold E low The system will increase the oxygen production power P O Set to zero. This measure is designed to protect the battery from damage caused by deep discharge and to ensure that the vehicle maintains basic functionality and safety when the battery is low.

[0112] Step S43: If the current battery power is greater than a preset first power threshold and the current battery power is less than or equal to a preset second power threshold, then determine the oxygen generation power based on the preset power threshold, the current battery power, and the rated power of the oxygen generator.

[0113] Specifically, when the current battery charge E current Given the preset first power threshold E low and preset second power threshold E high During this period, the system determines the current battery level, the preset battery threshold, and the rated power P of the oxygen generator. max The oxygen production capacity is dynamically calculated. The oxygen production capacity at this point can be determined using the following formula: P O =P max (1-E low / E current This ensures that when the battery is low, the oxygen production power will gradually decrease to extend battery life, while still providing the necessary oxygen production capacity within a certain range.

[0114] Step S45: If the current battery power is greater than the preset second power threshold, then the rated power is determined as the oxygen production power.

[0115] Specifically, when the current battery level is greater than a preset second battery level threshold E high At that time, the system determines the oxygen production power to be the rated power P. max At this point, the system can make full use of the remaining battery power to improve oxygen production efficiency and meet higher oxygen demands.

[0116] This embodiment sets the oxygen production power to zero when the current battery level is below a preset first threshold to prevent over-discharge and protect the battery's health. When the battery level is between the preset first and second thresholds, the system dynamically calculates the oxygen production power based on the real-time battery level, thereby rationally allocating energy and reducing unnecessary waste. When the battery level is above the preset second threshold, the system can provide full rated power to make full use of the remaining electrical energy. This coordinated control of active vibration reduction and oxygen production not only ensures the stable operation of the system under different operating conditions but also optimizes energy consumption management, improves overall work efficiency, and provides users with a safer and more comfortable user experience.

[0120] Specifically, the oil-free air compressor 1 is a four-cylinder oil-free air compressor. It draws in air through the intake filter 4, and while two cylinders compress the air, the other two cylinders simultaneously draw in air. This design ensures a continuous and stable air supply. The compressed air is cooled by a cooling duct and fan, and then delivered to the oxygen generator 2 through the compressor's intake and exhaust pipes 3.

This design guarantees the normal operation of the oxygen generator 2, allowing it to effectively separate oxygen and nitrogen using vacuum pressure swing adsorption (VPSA) technology, thereby flexibly supplying oxygen to users inside the vehicle through the oxygen supply pipe 5. Simultaneously, nitrogen returns to the oil-free air compressor 1 through the air compressor intake / exhaust pipe 3 and is discharged through the nitrogen exhaust silencer 6, helping to optimize energy consumption management.
