Description

Oxygen concentration adjustment method, control system, vehicle and storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 24, 2024, with application number 202410101963.4 and application name “Oxygen Concentration Adjustment Method, Control System, Vehicle and Storage Medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of signal control technology, and in particular to an oxygen concentration adjustment method, a control system, a vehicle, and a storage medium. Background Art

[0003] Different oxygen concentrations in the air have varying effects on the human body.

Neither of these methods allows for flexible adjustment of the ambient oxygen concentration to meet human needs.

[0050] The present application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts in the drawings or descriptions are numbered the same. Implementations not shown or described in the drawings are known to those of ordinary skill in the art. In the description of this application, the terms "first," "second," etc. are used solely to distinguish descriptions and are not to be construed as indicating or implying relative importance.

[0051] Please refer to Figures 1 to 4. The present application provides an oxygen concentration adjustment method, which can be applied to a control system 100, and each step of the method can be executed or implemented by the control system 100. Among them, the control system 100 can be deployed in a vehicle with a cabin, such as a car or a train. Of course, the control system 100 can also be deployed in other scenarios where hypoxia exists. For example, the control system 100 can be deployed in scenarios such as cabins and rooms at high altitudes to adjust the oxygen concentration in the corresponding space environment. It is understandable that the method and the control system 100 can be applied in a variety of environments where there is a risk of hypoxia, and there is no specific limitation on the application scenarios of the method and the control system 100.

[0052] In this embodiment, the control system 100 may include a processor and a memory. The memory stores a computer program, and when the computer program is executed by the processor, the control system 100 can perform the corresponding steps of the following oxygen concentration adjustment method.

[0053] 2 , in the control system 100 , the processor and the memory may be integrated into one body to serve as the controller 110 ; alternatively, the processor and the memory may be independent modules that exist independently of each other.

[0054] In this embodiment, the control system 100 may further include a sensor assembly for collecting oxygen concentration information in the target space. The sensor assembly may include a first oxygen sensor 120 for collecting oxygen concentration information in the target space. The sensor assembly may also include a second oxygen sensor 130 for collecting oxygen concentration information outside the target space (i.e., the external environment).

[0055] The control system 100 may also include an oxygen source 140. The oxygen source 140 may be, but is not limited to, an oxygen storage container containing oxygen or an oxygen generator for producing oxygen. As an example, the oxygen storage container may be an oxygen tank or oxygen cylinder. The oxygen generator may be a nitrogen-oxygen separation device or other device capable of generating oxygen. The oxygen source 140 is equipped with a solenoid valve to enable the controller 110 to start and stop the oxygen supply.

[0056] The oxygen supply line of the oxygen source device 140 can be directly connected to the target space to achieve independent oxygen supply to the target space. Alternatively, the oxygen supply line of the oxygen source device 140 can be connected to the indoor air supply line of the air conditioner 160 in the target space, with the indoor air supply line of the air conditioner 160 and the oxygen supply line cooperating to achieve oxygen supply. In this application, there is no specific limitation on the method of connecting the oxygen source device 140 to the target space.

[0057] It should be noted that the target space is a space where oxygen concentration adjustment is required. For example, the target space can be a car cabin, a room, etc., and can be flexibly determined according to actual conditions.

[0058] 3 , the control system 100 may further include a communication module 170. The communication module 170 may be used to implement wireless network communication and / or wired network communication.

[0059] When the control system 100 is deployed on a vehicle, the communication module 170 can be an onboard T-BOX. The communication module 170 can be used to establish a communication connection between the control system 100 and external devices such as user terminals and servers for data exchange. The controller 110 can be a domain controller, a thermal management controller, or other controller with control functions on the vehicle, eliminating the need for a separate controller. Alternatively, the user terminal can be a smartphone, tablet computer, or the like.

[0060] In this embodiment, the control system 100 can also communicate data with the display screen 150 (such as a vehicle-mounted display screen) and an alarm module (such as a vehicle speaker, horn, etc.).

[0061] Referring to FIG. 1 again, the oxygen concentration adjustment method may include the following steps:

[0062] Step 110, collecting an oxygen concentration signal corresponding to the target space;

[0063] Step 120, determining whether the oxygen concentration signal satisfies a preset condition for adjusting the oxygen concentration in the target space;

[0064] Step 130: When the oxygen concentration signal satisfies the preset condition, based on a control strategy corresponding to the oxygen concentration signal, the air conditioner in the target space is controlled to operate in an external circulation mode or the oxygen source device is controlled to operate so that the oxygen concentration in the target space is within a first preset concentration range representing safety.

[0065] The following is a detailed description of the steps of the oxygen concentration adjustment method:

[0066] In this embodiment, the sensor assembly in the control system 100 can be used to collect an oxygen concentration signal. The oxygen concentration signal can include both the oxygen concentration inside and outside the target space, or only the oxygen concentration inside the target space. For example, in the first scenario, if the sensor assembly includes both the first oxygen sensor 120 and the second oxygen sensor 130, the oxygen concentration inside the target space and the oxygen concentration outside the target space can be collected separately. In the second scenario, if the sensor assembly only includes the first oxygen sensor 120, the oxygen concentration inside the target space can be collected. For these two scenarios, the oxygen concentration adjustment methods for these two scenarios will be described below.

[0067] As an optional embodiment, in the first scenario, the sensor assembly includes both the first oxygen sensor 120 and the second oxygen sensor 130. Step 110, collecting the oxygen concentration signal corresponding to the target space, may include:

[0068] The first oxygen concentration in the target space is collected by the first oxygen sensor 120 , and the second oxygen concentration outside the target space is collected by the second oxygen concentration sensor to obtain the oxygen concentration signal.

[0069] In step 120, the preset conditions can be flexibly set according to actual conditions. For example, determining whether the oxygen concentration signal satisfies the preset conditions for adjusting the oxygen concentration in the target space may include:

[0070] When the first oxygen concentration is less than the second oxygen concentration, and the second oxygen concentration is within a second preset concentration range indicating safety, determining that the oxygen concentration signal meets the preset condition;

[0071] When both the first oxygen concentration and the second oxygen concentration are less than a first designated concentration, it is determined that the oxygen concentration signal meets the preset condition, wherein the first designated concentration is a value within the first preset concentration range.

[0072] Referring to Figure 4 , when the oxygen concentration in the air is between 19.5% and 23.9%, it meets the needs of human survival. When the oxygen concentration is lower than 19.5% or higher than 23.9%, it will have a negative impact on the body. Based on this, the first preset concentration range can be 19.5% to 23.9%, or a sub-range within the range of 19.5% to 23.9%.

[0073] The first preset concentration range may include a second preset concentration range, and the second preset concentration range may be the same as the first preset concentration range, or a subrange of the first preset concentration range. As an example, the second preset concentration range may be 21% to 23%.

[0074] As an example, the first specified concentration can be the minimum value in the first preset concentration range, such as 19.5%; or slightly greater than the minimum value in the first preset concentration range, such as 20%. The first specified concentration can be flexibly set based on the first preset concentration range and is not specifically limited here.

[0075] Accordingly, step 130, based on a control strategy corresponding to the oxygen concentration signal, controls the air conditioner in the target space to operate in an external circulation mode or controls the oxygen source device to operate, including:

[0076] When the first oxygen concentration is less than the second oxygen concentration and the second oxygen concentration is within the first preset concentration range, controlling the air conditioner to operate in the external circulation mode;

[0077] When both the first oxygen concentration and the second oxygen concentration are less than the first specified concentration, the oxygen source device is controlled to operate, or the air conditioner is controlled to operate in an internal circulation mode and the oxygen source device is controlled to operate to supply oxygen to the target space.

[0078] Understandably, the control strategy in step 130 aims to maintain the oxygen concentration in the target space within the first pre-read concentration range. This control strategy can be flexibly configured based on actual circumstances. For example, if the oxygen concentration in the external environment is higher than that in the target space, the air conditioner 160 in the target space can be controlled to operate in an external circulation mode, thereby delivering external air into the target space to adjust the oxygen concentration in the target space and prevent the oxygen concentration from being too low. It should be noted that the air conditioner 160 can be replaced with a fan.

[0079] When both the first oxygen concentration and the second oxygen concentration are less than the first specified concentration (for example, 19.5%), it means that the oxygen concentrations of the outside world and the target space are both low. At this time, it is necessary to control the operation of the oxygen source device 140 to supply oxygen to the target space, thereby increasing the oxygen concentration in the target space. Of course, during the oxygen supply period of the oxygen source device 140, the air conditioner 160 can also operate in an internal circulation mode to mix the oxygen concentration in the target space evenly and prevent the provided oxygen from being lost to the outside world. In this way, adaptive adjustment of the oxygen concentration in the target space can be achieved, and a safe and healthy breathing environment can be provided for personnel.

[0080] It should be noted that to prevent excessive oxygen concentration in the target space, the oxygen generator will cease operation when the oxygen concentration in the target space reaches a second specified concentration. The second specified concentration is greater than or equal to the first specified concentration and less than or equal to the maximum value in the first preset concentration range. As an example, the first specified concentration may be 19.5%, and the second specified concentration may be 21%.

[0081] As an optional embodiment, if the second oxygen sensor 130 in the control system 100 is not functioning properly but the first oxygen sensor 120 is functioning properly, or if the sensor assembly only includes the first oxygen sensor 120 that is functioning properly, in such a case, step 110 of collecting the oxygen concentration signal corresponding to the target space may include:

[0082] The first oxygen concentration in the target space is collected by the first oxygen sensor 120 to obtain the oxygen concentration signal.

[0083] Accordingly, step 120, determining whether the oxygen concentration signal satisfies a preset condition for adjusting the oxygen concentration in the target space, may include:

[0084] and determining whether the first oxygen concentration is within a first preset concentration range, wherein if the first oxygen concentration is within the first preset concentration range, it indicates that the oxygen concentration signal meets the preset condition; if the first oxygen concentration is not within the first preset concentration range, it indicates that the oxygen concentration signal does not meet the preset condition.

[0085] Accordingly, step 130, based on the control strategy corresponding to the oxygen concentration signal, controlling the air conditioner 160 in the target space to operate in an external circulation mode or controlling the oxygen source device 140 to operate, may include:

[0086] controlling the air conditioner 160 to operate in an external circulation mode based on a first control strategy corresponding to the first oxygen concentration; and controlling the oxygen source device 140 to operate to deliver oxygen to the target space if the oxygen concentration in the target space is not within the first preset concentration range after the air conditioner 160 operates in the external circulation mode for a preset period of time;

[0087] Alternatively, based on a second control strategy corresponding to the first oxygen concentration, the oxygen source device 140 is controlled to operate so as to deliver oxygen to the target space.

[0088] It is understandable that if the sensing component in the control system 100 only includes the first oxygen sensor 120 that can operate normally, and does not include the second oxygen sensor 130, the hardware cost of the control system 100 can be reduced. Based on this, when the above-mentioned preset conditions are met, during the period of adjusting the oxygen concentration of the target space, the air conditioner 160 can be controlled to operate in an external circulation mode to input air from the external environment into the target space. After the air conditioner 160 operates in an external circulation mode for a period of time (that is, a preset time, which can be flexibly set according to actual conditions, usually a shorter time, such as 1 minute), if the oxygen concentration of the target space is still not within the first preset concentration range, at this time, the oxygen source device 140 is controlled to operate to supply oxygen to the target space, thereby increasing the oxygen concentration; if the oxygen concentration of the target space is within the first preset concentration range, the air conditioner 160 can be controlled to continue to operate in an external circulation mode for a period of time or directly stop running.

[0089] Of course, when the above-mentioned preset conditions are met, the operation of the oxygen supply equipment can also be directly controlled to directly increase the oxygen concentration in the target space, which is conducive to quickly adjusting the oxygen concentration.

[0090] Based on the above design, if the vehicle is traveling in a plateau area, the control system 100 is deployed behind the vehicle. The control system 100 can be used to replenish the oxygen in the passenger compartment to ensure that the oxygen concentration in the passenger compartment is within the optimal range suitable for the human body, thereby ensuring the driving safety and riding safety of the driver and passengers.

[0091] As an optional implementation, the method may further include:

[0092] When the oxygen source device 140 is running, when the oxygen concentration in the target space is greater than a second specified concentration, the oxygen source device 140 is controlled to stop running, wherein the second specified concentration is greater than or equal to the first specified concentration and less than or equal to the maximum value in the first preset concentration range, and the first specified concentration is a value in the first preset concentration range.

[0093] In this embodiment, to prevent excessive oxygen concentration in the target space and reduce system energy consumption, the oxygen source device 140 can be controlled to stop operating, thereby stopping oxygen supply, when the oxygen concentration in the target space is detected to be greater than a second specified concentration. The second specified concentration can be flexibly set based on actual conditions. For example, the second specified concentration can be 23.9%.

[0094] As an optional implementation, the method may further include:

[0095] The real-time oxygen concentration collected from the target space is sent to the display screen 150 and / or the server, wherein the display screen 150 is used to display the real-time oxygen concentration, and the server is used to send the real-time oxygen concentration to the user terminal when receiving a query request from the user terminal.

[0096] As an example, when the method is applied to a vehicle, the first oxygen sensor 120 can collect the real-time oxygen concentration in the vehicle (or cabin). The control system 100 can send the real-time oxygen concentration to the vehicle display screen, and the vehicle display screen can directly and synchronously display the real-time oxygen concentration. In addition, the control system 100 can send the real-time oxygen concentration to the server through the communication module 170. The user can view the real-time oxygen concentration in the current vehicle from the server through the corresponding APP (Application) in the smartphone. In this way, the control system 100 can be linked with the vehicle display screen and the user terminal.

[0097] As an optional implementation, the method may further include:

[0098] When the real-time oxygen concentration collected from the target space is not within the first preset concentration range, an alarm signal is sent to the alarm module and / or the user terminal, so that the alarm module and / or the user terminal sends an alarm prompt based on the alarm signal.

[0099] In this embodiment, the alarm module can be a vehicle horn, onboard display, or the like, and can issue an alarm through one or more means, such as sound, light, or a pop-up window. Using the alarm module and user terminal, the driver and passengers can be dynamically informed of the oxygen concentration in the passenger compartment to ensure driving safety.

[0100] As an optional implementation, the method may further include:

[0101] Receiving an operation instruction input by a user through a local input module or a user terminal;

[0102] Respond to the operation instruction.

[0103] As an example, the local input module can be a touch-enabled onboard display screen on a vehicle. Users can input operating instructions to the control system 100 via the onboard display screen or a user terminal. The operation content corresponding to the operating instruction can be flexibly set based on actual conditions, thus facilitating manual operation by the user. The operating instruction is used to:

[0104] Cancel the alarm;

[0105] Alternatively, when the oxygen concentration in the target space is greater than the minimum value of the first preset concentration range, the oxygen source device 140 is turned off; that is, when the oxygen concentration is less than or equal to the minimum value of the first preset concentration range, the control system 100 does not respond to the operation instruction to avoid safety risks caused by turning off the oxygen source device 140 when the oxygen concentration is low;

[0106] Or when the oxygen concentration in the target space is less than the maximum value in the first preset concentration range, the oxygen source device 140 is turned on, that is, when the oxygen concentration is greater than or equal to the maximum value in the first preset concentration range, the control system 100 does not respond to the operation instruction to avoid turning on the oxygen source device 140 when the oxygen concentration is high and causing safety risks.

[0107] The following is an example of the implementation process of the method based on a vehicle scenario, where the control system 100 is provided with a first (in-vehicle) oxygen sensor and a second (out-vehicle) oxygen sensor, as follows:

[0108] In the vehicle, the controller 110 in the control system 100 receives the in-vehicle oxygen concentration signal and the out-vehicle oxygen concentration signal collected by the in-vehicle oxygen sensor and the out-vehicle oxygen sensor respectively, and controls the HVAC and nitrogen-oxygen separation equipment based on the received oxygen concentration signal. The communication method between each sensor and the controller 110 can be CAN / LIN or wireless communication. The controller 110 drives the HVAC and nitrogen-oxygen separation equipment through hard wire / CAN / LIN or wireless communication. The nitrogen-oxygen separation equipment can filter the air outside the vehicle to obtain oxygen and nitrogen. Oxygen is used to be input into the vehicle, and nitrogen is discharged to the outside. The controller 110 communicates with the vehicle display screen through CAN / CANFD / Ethernet and other methods. The controller 110 can communicate with the server and user terminal through a wireless network.

[0109] The in-vehicle oxygen sensor detects the in-vehicle oxygen concentration M1, while the out-vehicle oxygen sensor detects the out-vehicle oxygen concentration M2. Controller 110 receives the oxygen concentration signals. When M1 is less than M2, and M2 is within the range of 19.5% to 23.9%, controller 110 adjusts the HVAC operating mode to external circulation until M1 and M2 are equal. If M2 is less than the minimum standard value of 19.5%, and M1 is less than the minimum standard value of 19.5%, controller 110 adjusts the HVAC operating mode to internal circulation and activates the vehicle's nitrogen oxide separation device. When the in-vehicle oxygen concentration M1 is within the range of 19.5% to 23.9%, controller 110 sends a signal to shut down the nitrogen oxide separation device.

[0110] In addition, the user can read the in-vehicle oxygen concentration M1 through the user terminal. Based on the received oxygen concentration signal, the controller 110 autonomously turns the nitrogen and oxygen separation device on or off through the user terminal. The user can use the user terminal to read the in-vehicle oxygen concentration data in real time. When the in-vehicle oxygen concentration M1 exceeds 23.9%, the user terminal issues an alarm, notifying the user of the excessive oxygen concentration and confirming whether to shut down the nitrogen and oxygen separation device. The user can choose to shut down the in-vehicle system or not.

[0111] If the user chooses not to turn off the nitrogen and oxygen separation equipment, the controller 110 will send out an alarm signal and display it on the vehicle display screen to remind the driver that the oxygen concentration in the car exceeds the standard, and remind the user to open the window or turn off the nitrogen and oxygen separation equipment to reduce the oxygen concentration in the car and ensure the user's safe use of the car.

[0112] In this embodiment, the processor may be an integrated circuit chip having signal processing capabilities. The above-mentioned processor may be a general-purpose processor. For example, the processor may be a central processing unit (CPU), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, a discrete gate or transistor logic device, or a discrete hardware component, and may implement or execute the various methods, steps, and logic block diagrams disclosed in the embodiments of the present application.

[0113] The memory may be, but is not limited to, a random access memory, a read-only memory, a programmable read-only memory, an erasable programmable read-only memory, an electrically erasable programmable read-only memory, etc. In this embodiment, the memory may be used to store a first preset concentration range, a second preset concentration range, a first designated concentration, a second designated concentration, etc. Of course, the memory may also be used to store a program, and the processor executes the program after receiving an execution instruction.
