[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0027] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0028] Oxygen production equipment: refers to equipment that uses air compressors and molecular sieves to separate oxygen and nitrogen in the air to obtain air with a high oxygen concentration.

[0029] As introduced in the background technology, in the prior art, a parking air conditioner is installed on a car, but the narrow space inside the car can easily cause hypoxia. To solve the above problem, the embodiments of the present application provide a parking air conditioner, a parking air conditioner control method, a parking air conditioner control device and an air conditioning system.

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0031] The present application provides a parking air conditioner, such as Figure 1 and Figure 2 As shown, including:

[0032] An air conditioner body, the air conditioner body comprising an external unit 10 and an internal unit 11, the external unit being located outside the vehicle, and the internal unit being located inside the cab of the vehicle;

[0033] The oxygen generator 12 is installed on the external unit. The outlet 13 of the oxygen delivery pipe of the oxygen generator is located on the side of the air outlet of the internal unit. The oxygen generator is used to produce oxygen and deliver the oxygen to the cab of the vehicle through the oxygen delivery pipe.

[0034] Through this embodiment, the air conditioner is combined with the oxygen generator, and the outlet of the oxygen delivery pipe is designed on the side of the air outlet of the interior unit to better diffuse oxygen into the car, which greatly improves the air quality in the car and makes people rest more comfortably and at ease in the car without worrying about hypoxia.

[0035] Specifically, the air conditioner is combined with the oxygen generator, and the oxygen generator is designed on the external unit of the air conditioner to better isolate the noise of the oxygen compressor and ensure a quiet environment in the cab. The outlet of the oxygen delivery pipe is designed on the side of the air outlet of the internal unit to better diffuse oxygen into the car.

[0036] Specifically, the parking air conditioner is combined with oxygen generator to regulate the air in the car and ensure the oxygen content in the air, while ensuring a quiet environment inside the car. This solves the problem of people being prone to hypoxia when turning on the air conditioner to rest in the car, making it more comfortable and reassuring for people to rest in the car.

[0037] Specifically, by integrating the oxygen generator onto the parking air conditioner and combining the sensors on the equipment with the control program, intelligent control can be achieved, which can adjust the temperature of the vehicle environment and ensure the stability of the oxygen concentration in the vehicle, allowing people to rest comfortably and safely in the vehicle. At the same time, the oxygen generator can avoid frequent start and stop problems due to fluctuations in oxygen concentration, thereby increasing the service life of the oxygen generator.

[0038] Specifically, the oxygen production equipment can be designed to be placed on the outer unit housing and on a common housing with the air conditioner outer unit, and the oxygen outlet can be designed to be on the left side of the inner unit air outlet.

[0039] Specifically, the air conditioner body refers to the core component of the entire air conditioning system, including cooling or heating equipment, and is usually composed of two major parts: the outdoor unit and the indoor unit. The outdoor unit usually contains the compressor, condenser and other main components, which are responsible for processing the high-temperature and high-pressure refrigerant in the air conditioning system; the indoor unit contains the evaporator, fan, etc., which is responsible for blowing the processed air into the room.

[0040] Specifically, the external unit is installed outside the vehicle, which can be the roof, rear or any suitable location to ensure that the noise generated during the oxygen production process is isolated outside the cab, providing a quiet driving environment. The internal unit is located inside the cab and directly delivers treated air to the interior of the vehicle.

[0041] Specifically, oxygen generator is a device that can separate oxygen from the air, usually including key components such as air compressor and molecular sieve. The oxygen generator mentioned here is installed on the external unit of the air conditioning system, taking advantage of the layout of the air conditioning system and avoiding the noise problem that may be caused by installing it directly in the cab.

[0042] Specifically, the oxygen delivery pipe is a pipe connecting the oxygen generator and the air conditioner indoor unit, used to transmit the oxygen produced by the oxygen generator. The outlet is designed on the side of the indoor unit's air outlet. The purpose of this is to ensure that the oxygen can be evenly diffused throughout the cab, rather than blowing directly to the passengers, causing the problem of excessive local oxygen concentration. It is also conducive to the mixing of oxygen and the air in the cab, improving the uniformity of oxygen distribution.

[0043] Specifically, the oxygen produced by the oxygen generator is ultimately transported to the interior of the vehicle's cab to increase the oxygen concentration in the vehicle, providing the driver and passengers with a healthier and more comfortable breathing environment.

[0044] In addition, in order to further improve the diffusion efficiency of oxygen in the cab, a more complex oxygen delivery pipeline system can be designed, such as using a porous diffuser or a specially shaped air duct to enhance the mixing effect of oxygen and air.

[0045] In addition, the oxygen production equipment is designed to be more modular and portable, so that it can be easily installed and disassembled, and is convenient for use in different vehicle models or scenarios.

[0046] In a specific implementation process, the parking air conditioner further includes an oxygen concentration sensor, which is located on the interior unit and is used to detect the oxygen concentration inside the cab of the vehicle.

[0047] In this solution, the oxygen concentration sensor is a device that can detect and measure the oxygen content in the environment. The oxygen concentration sensor is designed and installed on the air conditioner, so that the sensor can detect the oxygen concentration inside the cab most directly and accurately. It can monitor the oxygen level in the cab in real time to ensure the real-time and accuracy of the data.

[0048] Specifically, the oxygen concentration sensor can provide real-time feedback on changes in oxygen content in the cab, which is crucial to ensuring the health and safety of the occupants. In the confined space of a vehicle, especially when the parking air conditioner is running for a long time, the oxygen concentration may drop, causing fatigue, hypoxia, and even life-threatening conditions for the occupants. Through real-time monitoring by sensors, the working status of the oxygen generator can be adjusted in time to maintain a suitable oxygen concentration environment.

[0049] Specifically, combined with the feedback data from the oxygen concentration sensor, the oxygen generator can intelligently adjust its working mode. When it detects that the oxygen concentration is lower than the set safety or health threshold, the oxygen generator will automatically increase the oxygen production efficiency to quickly increase the oxygen level in the car; when the oxygen concentration reaches or exceeds the threshold, the oxygen generator can reduce the oxygen production efficiency or even stop working to avoid safety hazards caused by excessive oxygen concentration (such as oxygen poisoning or fire risk).

[0050] Specifically, through the intelligent control of the oxygen concentration sensor, the over-operation of the oxygen generator can be avoided, thereby saving energy and reducing unnecessary resource consumption. In actual use, this intelligent control can optimize the operating efficiency of the oxygen generator, extend the service life of the equipment, and reduce energy waste.

[0051] Specifically, traditional oxygen generators may start and stop frequently due to slight fluctuations in oxygen concentration, which not only affects the service life of the equipment, but may also generate noise and increase energy consumption. Through the linkage control of oxygen concentration sensors and oxygen generators, smoother oxygen concentration management can be achieved, avoiding frequent start and stop of equipment, improving user experience, and also improving equipment stability.

[0052] Specifically, the oxygen concentration sensor can not only detect oxygen concentration, but also monitor whether there is an abnormal heat source. If an abnormal increase in temperature is detected in the cab, it can trigger the shutdown mechanism of the oxygen generator to prevent potential fire or explosion risks, thereby further enhancing the safety performance of the system.

[0053] Specifically, when the air conditioner is turned on, the outdoor oxygen production equipment starts to operate and begins to produce oxygen. The air with high oxygen concentration is transported into the room through pipes. The processed oxygen is evenly mixed into the indoor air under the blowing action of the indoor unit to ensure the stability of the oxygen concentration in the car. The stepless adjustment and coordinated control logic of the oxygen production equipment can avoid the problem of frequent start and stop of the oxygen production equipment due to fluctuations in oxygen concentration.

[0054] The method embodiments provided in the embodiments of the present application can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 3 FIG. 1 is a hardware structure block diagram of a mobile terminal for a parking air conditioner control method according to an embodiment of the present invention. Figure 3 As shown, the mobile terminal may include one or more ( Figure 3 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 104 for storing data, wherein the mobile terminal may also include a transmission device 106 and an input / output device 108 for communication functions. It can be understood by those skilled in the art that Figure 3 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 3 More or fewer components as shown, or with Figure 3 Different configurations are shown.

[0055] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the display method of device information in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the above method is implemented. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories can be connected to the mobile terminal via a network. Examples of the above-mentioned network include but are not limited to the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof. The transmission device 106 is used to receive or send data via a network. The above-mentioned specific examples of the network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0056] In this embodiment, a method for controlling a parking air conditioner running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0057] Figure 4 FIG. 1 is a flow chart of a method for controlling a parking air conditioner according to an embodiment of the present application. Figure 4 As shown, the method comprises the following steps:

[0058] Step S401, obtaining the oxygen concentration inside the cab of the vehicle;

[0059] Specifically, the oxygen concentration sensor is used to collect oxygen concentration data in the cab. This step is the basis for subsequent intelligent control, ensuring that oxygen content information in the cab environment can be obtained in real time. By monitoring oxygen concentration in real time through sensors, changes in oxygen levels in the cab can be detected in a timely manner, which is crucial to ensuring the health and safety of people in the car.

[0060] Step S402, controlling the oxygen production equipment to operate according to the oxygen concentration.

[0061] Specifically, after obtaining the oxygen concentration data in the cab, the working state of the oxygen generator is determined based on this data. If the oxygen concentration is lower than the preset safety threshold, the oxygen generator will increase its working intensity and speed up the oxygen production rate; conversely, if the oxygen concentration is sufficient or higher than the threshold, the oxygen generator will reduce its working intensity or stop working to avoid excessive oxygen concentration.

[0062] By intelligently adjusting the working state of the oxygen generator according to the oxygen concentration, the oxygen concentration in the cab can be maintained within a safe and comfortable range, avoiding insufficient or excessive oxygen. This approach of dynamically adjusting the power of the oxygen generator can effectively avoid excessive work of the equipment and reduce unnecessary energy consumption. It can also extend the service life of the oxygen generator and reduce the wear and tear on the equipment caused by frequent starting and stopping. The control logic also takes into account the risk of preventing oxygen poisoning and fire. When the oxygen concentration is too high or an abnormal heat source is detected, the oxygen generator will automatically shut down to ensure the overall safety of the air conditioner. Through intelligent control, users do not need to make manual adjustments, and will automatically respond to changes in oxygen concentration in the cab, improving convenience and comfort of use.

[0063] Through this embodiment, by obtaining the oxygen concentration data in the cab in real time and intelligently adjusting the working mode of the oxygen generator according to the data, accurate control of the oxygen concentration in the cab is achieved. This control method can not only ensure the health and safety of the occupants, but also improve the energy efficiency of the air conditioner, extend the service life of the equipment, and optimize the user experience.

[0064] Specifically, the present application proposes an oxygen-generating parking air conditioner, which combines the oxygen-generating equipment with the parking air conditioner, which can not only ensure the temperature regulation in the car but also ensure the appropriate oxygen concentration in the car to prevent people in the car from hypoxia or oxygen poisoning. At the same time, through the stepless adjustment and coordinated control logic of the oxygen-generating equipment, the problem of frequent start and stop of the oxygen-generating equipment due to fluctuations in oxygen concentration can be avoided.

[0065] Specifically, the solution of the present application effectively combines the temperature regulation of the parking air conditioner and the oxygen regulation in the car, greatly improving the air quality in the car, making people more comfortable and assured to rest in the car without worrying about the problem of hypoxia. At the same time, it avoids the problem of frequent start and stop of the oxygen generator due to fluctuations in oxygen concentration, and increases the service life of the oxygen generator.

[0066] Specifically, an oxygen concentration detection sensor is designed on the air conditioner to monitor the changes in oxygen concentration in the car. The oxygen generator is designed to be infinitely adjustable, and different oxygen production efficiencies can be selected according to the number of people and the rate of change of oxygen concentration in the car. The relevant oxygen production mode is automatically selected according to different situations in the car, and intelligent control is achieved to ensure the stability of oxygen. It solves the problem of oxygen supply in the car for different people and the problem of unstable oxygen in the car, while avoiding the problem of frequent start and stop of oxygen generators due to fluctuations in oxygen concentration, increasing the service life of oxygen generators, and realizing intelligent adjustment and ensuring the oxygen concentration in the car.

[0067] In addition, different oxygen production efficiencies can be selected according to the number of people in the car, which is an important part of the intelligent control of the oxygen production system in the parking air conditioner. The realization of this function can ensure that the oxygen concentration in the car is maintained at an appropriate and safe level under different number of people, avoiding oxygen waste or problems of too high or too low oxygen concentration.

[0068] Install occupancy sensors inside the vehicle, such as infrared sensors, pressure sensors, or camera-based facial recognition technology. These sensors can monitor the changes in the number of people in the vehicle in real time and transmit data to the control system, which adjusts the efficiency of the oxygen generator according to the number of people. For example, when the number of people increases, the oxygen generation efficiency is automatically increased to ensure sufficient oxygen supply; when the number of people decreases, the oxygen generation efficiency is reduced accordingly to avoid excess oxygen.

[0069] Using machine learning algorithms, the air conditioning system can learn the changing patterns of the number of people in the vehicle usage mode, predict the future number of people, adjust the oxygen production efficiency in advance, and provide a more personalized and comfortable user experience. Develop a learning algorithm based on historical data to predict future personnel needs by analyzing the vehicle usage (such as time, location, driving mode, etc.) and the changing patterns of the number of people in the car. Adjust the operating status of the oxygen production equipment in advance according to the prediction results to ensure that the oxygen concentration is always stable within the ideal range.

[0070] In a specific implementation process, the operation of the oxygen production equipment is controlled according to the oxygen concentration, which can be achieved through the following steps: calculating the difference between the oxygen concentration and the preset oxygen concentration to obtain a first calculation result; calculating the quotient of the first calculation result and the preset oxygen concentration to obtain a second calculation result; and controlling the operation of the oxygen production equipment according to the size of the first calculation result and the size of the second calculation result.

[0071] In this solution, the difference and deviation percentage obtained through mathematical calculation can be used to fine-tune the control of oxygen concentration, avoiding the concentration instability problem that may be caused by simple "on" or "off" control. The oxygen production efficiency is dynamically adjusted according to the gap between the oxygen concentration and the target value, ensuring a quick response when the oxygen concentration needs to be increased, and timely reducing the power when the oxygen concentration approaches or reaches the target, avoiding waste of resources.

[0072] Specifically, the current oxygen concentration in the cab is measured first, and then compared with the preset oxygen concentration value. The difference (first calculation result) represents the gap between the current oxygen concentration and the target concentration, which is the key basis for judging whether the working state of the oxygen generator needs to be adjusted.

[0073] For example, if the preset oxygen concentration is 21% and the currently measured oxygen concentration is 19%, the first calculated result is a difference of -2%.

[0074] After obtaining the difference, the calculation is continued, and the second calculation result in the form of a percentage is obtained by dividing the difference by the preset oxygen concentration. This calculation result can more intuitively reflect the degree of deviation of the current oxygen concentration from the target concentration and is an important control variable.

[0075] This ratio reflects the degree to which the current oxygen concentration deviates from the preset value. Continuing with the above example, we will get -2% / 21% ≈ -9.5%.

[0076] The adjustment strategy of the oxygen generator is determined based on the calculated difference and deviation percentage. When the first calculation result (i.e., the difference) is large, the oxygen generator can be adjusted to a higher power to quickly increase the oxygen concentration; when the second calculation result (deviation percentage) is large, it means that the current oxygen concentration is far below the target value, and the oxygen generator can be operated at full load. On the contrary, if the first calculation result is small, it means that the oxygen concentration is close to the target value, which will reduce the power of the oxygen generator to avoid excessive oxygen concentration; if the second calculation result is small, the oxygen generator can maintain a lower or current power operation to keep the oxygen concentration stable.

[0077] In some embodiments, the oxygen production equipment is controlled to operate according to the size of the first calculation result and the size of the second calculation result, which can be specifically achieved through the following steps: when the first calculation result is greater than or equal to the difference threshold, and the second calculation result is greater than or equal to the first percentage threshold, the oxygen production equipment is controlled to stop operating; when the first calculation result is less than the difference threshold, and the second calculation result is less than or equal to the second percentage threshold, the oxygen production equipment is controlled to operate at maximum power, wherein the first percentage threshold is greater than the second percentage threshold.

[0078] In this solution, by setting the difference threshold and percentage threshold, the oxygen concentration in the cab can be controlled more accurately to ensure that it is neither too low nor too high, and is maintained within a safe and comfortable range. When the oxygen concentration in the cab is low, running the oxygen generator at maximum power can quickly increase the oxygen concentration, quickly respond to the body's demand for oxygen, and avoid the body's hypoxia. The oxygen generator automatically stops working when the oxygen concentration reaches or exceeds the target value, avoiding unnecessary energy waste. At the same time, when the oxygen concentration is low but the deviation is not large, the maximum power operation is only started when necessary, achieving a more efficient and energy-saving operation mode.

[0079] Specifically, when the difference between the current oxygen concentration and the target preset oxygen concentration (the first calculation result) exceeds the set difference threshold, and the ratio of this difference to the preset oxygen concentration (the second calculation result) exceeds the first percentage threshold, the oxygen generator will be controlled to stop working. This indicates that the current oxygen concentration in the cab has not only reached or exceeded the target value, but also exceeded the target value to a large extent. At this time, stopping the oxygen generator can avoid excessive oxygen concentration and prevent safety problems such as oxygen poisoning or fire.

[0080] On the contrary, if the difference between the oxygen concentration and the target value is less than the difference threshold, and the ratio of this difference to the preset oxygen concentration is less than or equal to the second percentage threshold, it means that the current oxygen concentration is lower than the target value and the degree of deviation from the target value is not large, but the oxygen concentration needs to be increased quickly to meet the preset safety and health standards. At this time, controlling the oxygen generator to operate at maximum power can quickly increase the oxygen concentration to meet the human body's demand for oxygen.

[0081] Assume that the preset oxygen concentration is 21%, the difference threshold is ±2%, the first percentage threshold is 10%, and the second percentage threshold is 5%.

[0082] The oxygen concentration sensor monitors the oxygen concentration in the cab in real time. Assuming that the current oxygen concentration is 22.5%, the first calculation result is 1.5% (1.5% higher than the preset value), and the second calculation result is 1.5% / 21%≈7.14%, which exceeds the first percentage threshold (10%).

[0083] Since the current oxygen concentration is high and the ratio of the deviation to the preset oxygen concentration exceeds the first percentage threshold, the oxygen production equipment will be controlled to stop working to prevent safety hazards caused by excessive oxygen concentration, such as oxygen poisoning or fire risks.

[0084] If the current oxygen concentration is 20.5%, the first calculation result is -0.5% (0.5% lower than the preset value), and the second calculation result is 0.5% / 21%≈2.38%, which is less than the second percentage threshold (5%). In this case, it is judged that the oxygen concentration in the cab is slightly low but the deviation is not large. To ensure the health of personnel, the oxygen generator will be controlled to operate at maximum power to quickly increase the oxygen concentration to the preset level to meet the human body's demand for oxygen.

[0085] During the subsequent operation process, the changes in oxygen concentration will be continuously monitored. If the oxygen concentration is found to be close to the preset value or reaches the second percentage threshold, the oxygen generator will automatically reduce the power to maintain the stability of the oxygen concentration and avoid unnecessary energy waste and excessive use of equipment.

[0086] In a specific implementation process, the oxygen production equipment is controlled to operate according to the oxygen concentration through the following steps: when the second calculation result is less than the first percentage threshold and the second calculation result is greater than the second percentage threshold, the rate of change of the oxygen concentration is obtained, wherein the rate of change is the speed of change of the oxygen concentration within the target time; and the oxygen production equipment is controlled to operate according to the rate of change.

[0087] In this solution, by continuously monitoring the oxygen concentration and calculating its rate of change, the working state of the oxygen generator can be adjusted in a timely manner to ensure that the oxygen concentration is maintained within the preset health and safety range and to avoid problems with excessively high or low concentrations. The rate of change can be used to quickly identify the trend of oxygen concentration fluctuations and adjust the power of the oxygen generator in a timely manner to respond more quickly to changes in oxygen concentration and maintain the stability of the oxygen environment in the cab.

[0088] Specifically, the oxygen concentration sensor continuously monitors the oxygen concentration and records its changes over time. When it is determined that the ratio between the current oxygen concentration and the preset oxygen concentration (the second calculation result) is less than the first percentage threshold (which usually means that the oxygen concentration is close to the preset value but there is still a slight deviation), and this ratio is greater than the second percentage threshold (indicating that the oxygen concentration deviates less and is within an adjustable range), the rate of change of the oxygen concentration will be calculated. The rate of change refers to the speed at which the oxygen concentration changes over a period of time (target duration). It reflects the fluctuation trend of the oxygen concentration over time and is an important basis for dynamically adjusting the working state of the oxygen production equipment.

[0089] The obtained oxygen concentration change rate is used to intelligently control the working state of the oxygen generator. If the change rate shows that the oxygen concentration is slowly rising, the working efficiency of the oxygen generator can be reduced to keep the oxygen concentration stable and avoid excessive concentration. Conversely, if the change rate shows that the oxygen concentration is slowly decreasing, the operating efficiency of the oxygen generator will be improved to compensate for the decrease in oxygen concentration. This control strategy can ensure that the oxygen concentration always fluctuates stably around the preset value, avoiding safety and comfort issues caused by large fluctuations.

[0090] For example, the preset oxygen concentration is set to 21%, the first percentage threshold is set to 5%, the second percentage threshold is set to 1%, and the target duration is set to 5 minutes.

[0091] Assuming that the current oxygen concentration monitored is 21.2%, the second calculation result is 21.2% / 21%-100%≈0.95%, that is, 0.95%, which is less than the first percentage threshold (5%) but greater than the second percentage threshold (1%), indicating that the oxygen concentration is slightly higher than the preset value, but the degree of deviation is within a controllable range.

[0092] In the past 5 minutes, if the oxygen concentration increased from 21.1% to 21.2%, the rate of change is (21.2%-21.1%) / 5 minutes=0.02% / minute, which indicates that the oxygen concentration is rising slowly.

[0093] Based on the change rate of 0.02% / minute, it is judged that the rising trend of oxygen concentration does not require high-intensity output of the oxygen generator. Therefore, the working efficiency of the oxygen generator will be automatically reduced, and the amount of oxygen produced will be reduced to prevent the oxygen concentration from further increasing beyond the safe range.

[0094] Assume that at a certain moment, the oxygen concentration drops to 20.9%, and the rate of change is (20.9%-21.2%) / 5 minutes=-0.06% / minute, which indicates that the oxygen concentration is slowly decreasing.

[0095] When the trend of decreasing oxygen concentration is identified, the output power of the oxygen generator will be automatically increased according to the rate of change to ensure that the oxygen concentration will not continue to drop below the preset health and safety level.

[0096] The rate of change of oxygen concentration will be continuously monitored, and the working status of the oxygen production equipment will be dynamically adjusted according to the positive or negative and size of the rate of change to ensure that the oxygen concentration is stable within the preset health and safety range.

[0097] In some embodiments, the operation of the oxygen production equipment is controlled according to the above-mentioned change rate, which can be specifically achieved through the following steps: when the above-mentioned change rate is greater than the change threshold, the output power of the above-mentioned oxygen production equipment is reduced; when the above-mentioned change rate is equal to the above-mentioned change threshold, the above-mentioned oxygen production equipment is controlled to maintain the current output power and continue to operate; when the above-mentioned change rate is less than the above-mentioned change threshold, the output power of the above-mentioned oxygen production equipment is increased.

[0098] In this solution, by real-time monitoring of the rate of change of oxygen concentration and intelligently adjusting the output power of the oxygen generator accordingly, the oxygen concentration in the cab can be accurately controlled to ensure that it is maintained within a safe and healthy standard range, avoiding the risks of excessively high or low concentrations. The operating efficiency of the oxygen generator is dynamically adjusted according to the actual changes in oxygen concentration to avoid unnecessary energy waste. When the oxygen concentration is close to the target value, the working intensity of the oxygen generator is reduced to achieve energy-saving operation and improve the overall energy utilization efficiency. This intelligent control strategy ensures the stability of oxygen concentration and provides a more comfortable and safe driving environment. Users can automatically adapt to environmental changes without manual adjustment, which improves ease of use and satisfaction.

[0099] When the rate of change of the monitored oxygen concentration (i.e., the speed at which the oxygen concentration changes over time) exceeds the preset change threshold, it means that the oxygen concentration is rising at a faster rate. In order to prevent the oxygen concentration from being too high, the output power of the oxygen generator will be reduced to reduce the production of oxygen, thereby avoiding potential health risks (such as oxygen poisoning) and safety issues (such as fire).

[0100] If the rate of change is equal to the change threshold, it indicates that the increase rate of oxygen concentration is just within the preset control range, and the output power of the oxygen generator does not need to be adjusted. The oxygen generator will be controlled to maintain the current output power and continue to operate to maintain a stable upward trend of oxygen concentration.

[0101] When the rate of change is lower than the change threshold, it is judged that the oxygen concentration is rising too slowly or is decreasing, which means that the oxygen concentration in the cab is lower than the preset health standard. In order to increase the oxygen concentration to a safe and healthy level, the output power of the oxygen generator will be increased to increase the oxygen production rate.

[0102] During the specific implementation process, after controlling the oxygen production equipment to work according to the oxygen concentration, the method further includes the following steps: obtaining the ambient temperature inside the cab of the vehicle; when the ambient temperature is greater than or equal to a temperature threshold, controlling the oxygen production equipment to stop working and generating an alarm message.

[0103] In this solution, by setting a temperature threshold and monitoring the temperature inside the cab, the oxygen generator can be automatically shut down when the temperature inside the cab is too high, effectively preventing potential safety hazards such as fire and protecting the lives and property of drivers and passengers. High temperature environments have an adverse effect on the normal operation of oxygen generators and may even damage the equipment. When the ambient temperature exceeds the safety threshold, the oxygen generator is automatically stopped to prevent the equipment from working under unsuitable conditions, which helps to extend the service life of the equipment and reduce maintenance costs. Generating alarm information can not only remind users that the current temperature inside the cab is abnormal, but also guide users to take corresponding cooling measures, such as turning on the air conditioning cooling mode, opening windows for ventilation, etc., which improves the user interactivity and safety of the system.

[0104] The built-in temperature sensor monitors the temperature in the cab in real time to ensure that environmental changes inside the cab can be grasped in a timely manner. The temperature threshold is a safety setting value used to determine whether the temperature in the cab is too high. The setting of this threshold is usually based on safety standards and the working environment restrictions of the equipment. For example, oxygen production equipment may not work properly in a high temperature environment, or a high temperature and oxygen-rich environment will increase the risk of fire.

[0105] When the ambient temperature inside the cab is detected to be greater than or equal to the temperature threshold, two actions are performed:

[0106] Control the oxygen generator to stop working: In order to avoid the safety risks that may be caused by the oxygen generator working in a high temperature environment, the oxygen generator will be automatically shut down to stop the production of oxygen.

[0107] Generate alarm information: In order to remind the user that the temperature inside the cab is too high, an alarm message will be generated and sent to prompt the user to take measures to reduce the temperature and ensure a safe environment in the cab.

[0108] For example, the temperature threshold inside the cab is set at 35°C (degrees Celsius), which is based on considerations of human comfort and safe operation of the oxygen production equipment.

[0109] Assume that on a hot summer day, the parking air conditioning system is turned on and the ambient temperature inside the cab gradually rises. The temperature sensor in the system detects that the current temperature inside the cab is 35°C.

[0110] Since the ambient temperature has reached the set temperature threshold, the parking air conditioning system takes immediate action according to the control strategy:

[0111] Oxygen generator stops working: Automatically shut down the oxygen generator and stop the production of oxygen to avoid the risk of fire caused by high temperature and oxygen-rich environment.

[0112] Generation and sending of alarm information: Alarm information is generated at the same time, and a warning message is displayed on the vehicle's display screen: "The temperature inside the cab is too high, please take cooling measures." It is accompanied by a sound alarm to remind people in the cab of the current temperature conditions, prompting them to take action to lower the temperature, such as turning on the air conditioning's cooling mode, opening windows for ventilation, or temporarily leaving the cab.

[0113] The user turns on the cooling mode of the air conditioner according to the alarm message, and detects that the temperature inside the cab begins to drop. When the temperature drops to a safe level (for example, 30°C), the oxygen generator is automatically restarted to resume oxygen production, and the alarm message is stopped.

[0114] Specifically, this solution can detect whether there is an abnormal heat source in the car. If the temperature of the heat source exceeds the set threshold, the oxygen production will be shut down to prevent fire.

[0115] Specifically, when the air conditioner is turned on, the sensor on the air conditioner starts to collect the temperature and air quality of the outdoor environment. The specific logic is as follows: Figure 5 As shown, the oxygen concentration p in the car and the program set concentration p1, ⊿p = p-p1. The rate of change of oxygen concentration during the detection period is set to β, and β>0 is set to positive change, that is, the trend of increasing oxygen concentration in the air, and the larger β is, the faster the oxygen concentration increases. β<0 is set to negative change, that is, the trend of decreasing oxygen concentration in the air, and the smaller β is, the faster the decrease rate is. When ⊿p>0 and ⊿p / p1>10%, the oxygen generator stops running and is in standby mode. When ⊿p<0 and ⊿p / p1<-10%, the oxygen generator is running at full load, and the oxygen production efficiency is the highest at this time.

[0116] When 10%>⊿p / p1>-10%, the following control logic is followed. When β>0, the output power of the oxygen generator decreases, the speed of the air compressor decreases, and the output pressure is reduced to slow down the oxygen production speed. The larger β is, the lower the output power of the oxygen generator is, and the slower the oxygen production efficiency is. When β<0, the output power of the oxygen generator increases, the speed of the air compressor increases, and the output pressure increases the oxygen production efficiency. The smaller β is, the greater the output power of the oxygen generator is, and the faster the oxygen production efficiency is. When β=0, the oxygen generator maintains the current output power and oxygen production efficiency. The β value is linearly inversely proportional to the output power and oxygen production efficiency of the oxygen generator. Ensure that the oxygen concentration in the car is not too high to cause oxygen poisoning, nor too low to cause hypoxia, and remain within a comfortable range. At the same time, the oxygen generator maintains good output power and good oxygen production efficiency to avoid frequent start and stop of the device, and increase the service life of the oxygen generator.

[0117] At the same time, the program designs a heat source temperature threshold W. When there is an abnormal heat source W1 in the environment and W1≥W, the control directly shuts down and issues an alarm. When W1<W (it can be considered that there is no abnormal heat source), the oxygen production module executes the above control program.

[0118] In addition, the compressor in this application can also complete the entire automatic cleaning process at normal working frequency.

[0119] In summary, the solution of the present application solves the problem of loud noise in the cab caused by the oxygen production module being installed on the indoor unit, solves the problem of people being prone to hypoxia when resting in a car with the air conditioner on, solves the problem of oxygen supply to different people in the car, solves the problem of unstable oxygen in the car, solves the problem of frequent starting and stopping of oxygen production equipment due to fluctuations in oxygen concentration in a small space in the car, and solves the problem of fire prone to occur due to the oxygen-rich environment in the car.

[0120] The embodiment of the present application also provides a control device for a parking air conditioner. It should be noted that the control device for the parking air conditioner in the embodiment of the present application can be used to execute the control method for the parking air conditioner provided in the embodiment of the present application. The device is used to implement the above-mentioned embodiments and preferred implementation modes, and the descriptions that have been made will not be repeated. As used below, the term "module" can implement a combination of software and / or hardware for a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0121] The following is an introduction to the control device of the parking air conditioner provided in the embodiment of the present application.

[0122] Figure 6 is a structural block diagram of a control device for a parking air conditioner according to an embodiment of the present application. Figure 6 As shown, the device comprises:

[0123] A first acquisition unit 100 is used to acquire the oxygen concentration inside the driving compartment of the vehicle;

[0124] The first control unit 200 is used to control the operation of the oxygen production equipment according to the oxygen concentration.

[0125] Through this embodiment, by obtaining the oxygen concentration data in the cab in real time and intelligently adjusting the working mode of the oxygen generator according to the data, accurate control of the oxygen concentration in the cab is achieved. This control method can not only ensure the health and safety of the occupants, but also improve the energy efficiency of the air conditioner, extend the service life of the equipment, and optimize the user experience.

[0126] In the specific implementation process, the first control unit includes a first calculation module, a second calculation module and a first control module. The first calculation module is used to calculate the difference between the above-mentioned oxygen concentration and the preset oxygen concentration to obtain a first calculation result; the second calculation module is used to calculate the quotient of the above-mentioned first calculation result and the above-mentioned preset oxygen concentration to obtain a second calculation result; the first control module is used to control the operation of the above-mentioned oxygen production equipment according to the size of the above-mentioned first calculation result and the size of the above-mentioned second calculation result.

[0127] In this solution, the difference and deviation percentage obtained through mathematical calculation can be used to fine-tune the control of oxygen concentration, avoiding the concentration instability problem that may be caused by simple "on" or "off" control. The oxygen production efficiency is dynamically adjusted according to the gap between the oxygen concentration and the target value, ensuring a quick response when the oxygen concentration needs to be increased, and timely reducing the power when the oxygen concentration approaches or reaches the target, avoiding waste of resources.

[0128] In some embodiments, the first control module includes a first control submodule and a second control submodule, the first control submodule is used to control the oxygen production equipment to stop working when the first calculation result is greater than or equal to the difference threshold, and the second calculation result is greater than or equal to the first percentage threshold; the second control submodule is used to control the oxygen production equipment to operate at maximum power when the first calculation result is less than the difference threshold, and the second calculation result is less than or equal to the second percentage threshold, wherein the first percentage threshold is greater than the second percentage threshold.

[0129] In this solution, by setting the difference threshold and percentage threshold, the oxygen concentration in the cab can be controlled more accurately to ensure that it is neither too low nor too high, and is maintained within a safe and comfortable range. When the oxygen concentration in the cab is low, running the oxygen generator at maximum power can quickly increase the oxygen concentration, quickly respond to the body's demand for oxygen, and avoid the body's hypoxia. The oxygen generator automatically stops working when the oxygen concentration reaches or exceeds the target value, avoiding unnecessary energy waste. At the same time, when the oxygen concentration is low but the deviation is not large, the maximum power operation is only started when necessary, achieving a more efficient and energy-saving operation mode.

[0130] During the specific implementation process, the first control unit includes an acquisition module and a second control module. The acquisition module is used to obtain the change rate of the above-mentioned oxygen concentration when the above-mentioned second calculation result is less than the first percentage threshold and the above-mentioned second calculation result is greater than the second percentage threshold, wherein the above-mentioned change rate is the change speed of the above-mentioned oxygen concentration within the target time length; the second control module is used to control the operation of the above-mentioned oxygen production equipment according to the above-mentioned change rate.

[0131] In this solution, by continuously monitoring the oxygen concentration and calculating its rate of change, the working state of the oxygen generator can be adjusted in a timely manner to ensure that the oxygen concentration is maintained within the preset health and safety range and to avoid problems with excessively high or low concentrations. The rate of change can be used to quickly identify the trend of oxygen concentration fluctuations and adjust the power of the oxygen generator in a timely manner to respond more quickly to changes in oxygen concentration and maintain the stability of the oxygen environment in the cab.

[0132] In some embodiments, the second control module includes a third control submodule, a fourth control submodule and a fifth control submodule. The third control submodule is used to reduce the output power of the above-mentioned oxygen production equipment when the above-mentioned change rate is greater than the change threshold; the fourth control submodule is used to control the above-mentioned oxygen production equipment to maintain the current output power and continue to operate when the above-mentioned change rate is equal to the above-mentioned change threshold; the fifth control submodule is used to increase the output power of the above-mentioned oxygen production equipment when the above-mentioned change rate is less than the above-mentioned change threshold.

[0133] In this solution, by real-time monitoring of the rate of change of oxygen concentration and intelligently adjusting the output power of the oxygen generator accordingly, the oxygen concentration in the cab can be accurately controlled to ensure that it is maintained within a safe and healthy standard range, avoiding the risks of excessively high or low concentrations. The operating efficiency of the oxygen generator is dynamically adjusted according to the actual changes in oxygen concentration to avoid unnecessary energy waste. When the oxygen concentration is close to the target value, the working intensity of the oxygen generator is reduced to achieve energy-saving operation and improve the overall energy utilization efficiency. This intelligent control strategy ensures the stability of oxygen concentration and provides a more comfortable and safe driving environment. Users can automatically adapt to environmental changes without manual adjustment, which improves ease of use and satisfaction.

[0134] During the specific implementation process, the above-mentioned device also includes a second acquisition unit and a second control unit. The second acquisition unit is used to obtain the ambient temperature inside the above-mentioned cab of the above-mentioned vehicle after controlling the above-mentioned oxygen production equipment to work according to the above-mentioned oxygen concentration; the second control unit is used to control the above-mentioned oxygen production equipment to stop working and generate alarm information when the above-mentioned ambient temperature is greater than or equal to the temperature threshold.

[0135] In this solution, by setting a temperature threshold and monitoring the temperature inside the cab, the oxygen generator can be automatically shut down when the temperature inside the cab is too high, effectively preventing potential safety hazards such as fire and protecting the lives and property of drivers and passengers. High temperature environments have an adverse effect on the normal operation of oxygen generators and may even damage the equipment. When the ambient temperature exceeds the safety threshold, the oxygen generator is automatically stopped to prevent the equipment from working under unsuitable conditions, which helps to extend the service life of the equipment and reduce maintenance costs. Generating alarm information can not only remind users that the current temperature inside the cab is abnormal, but also guide users to take corresponding cooling measures, such as turning on the air conditioning cooling mode, opening windows for ventilation, etc., which improves the user interactivity and safety of the system.
