Description

Technical Field

[0001] This invention relates to the field of vehicle equipment technology, and in particular to a general vehicle emergency auxiliary air supply system. Background Technology

[0002] Vehicle air pressure systems are a crucial component of modern trucks, buses, and some special-purpose vehicles, widely used in braking systems, clutch booster systems, suspension systems, and various pneumatic auxiliary equipment. Normal vehicle starting and operation often rely on sufficient compressed air reserves in the air pressure system. Especially after a vehicle has been parked for a period of time, due to minor leaks in the system or changes in ambient temperature, the air pressure in the reservoir may drop to a level where the parking brake cannot be released, preventing the vehicle from starting. Furthermore, in field operations, long-distance transportation, or emergency rescue scenarios, tire leaks and damage to air circuit components are frequent occurrences, necessitating an emergency device that can quickly and independently provide compressed air. Currently, various portable air pumps exist on the market, mainly divided into two categories: vehicle-mounted 12V / 24V DC air pumps and independent engine-driven air compressors. However, most existing products are single-function, primarily designed for tire inflation, and cannot simultaneously meet the diverse needs of rapidly inflating large vehicle air reservoirs and providing a continuous air supply for pneumatic tools. Although some high-end models are equipped with onboard air compressors, their inflation speed is relatively slow, and if the vehicle cannot start due to insufficient air pressure, the original compressor will also not work, creating a contradictory situation of "air is required to start, but starting requires air".

[0003] Existing portable air pumps typically contain only a simple pressure switch that stops operating when the output air pressure reaches a user-preset threshold. This control method has significant drawbacks: First, to control costs, these air pumps generally use low-precision pressure sensors, resulting in a large error between the detected value and the actual pressure. This leads to a discrepancy between the actual inflation pressure and the user's desired pressure, affecting inflation performance and even posing safety hazards. For example, when inflating tires, over-inflation may cause a tire blowout, while under-inflation may affect driving performance. Second, existing air pumps lack learning and adaptive capabilities. They cannot compensate for sensor errors or system characteristics based on data accumulated from multiple inflations of the same device (such as tires or air tanks in the same vehicle). The stopping pressure for each inflation relies on a fixed preset value or manual setting by the user, making it difficult to improve control accuracy. Third, existing devices generally lack self-diagnostic functions. When leaks occur in the air circuit or connections are not properly connected, they cannot be identified and alarmed in time, causing the air compressor to run ineffectively for extended periods, wasting energy and potentially damaging the equipment. Furthermore, in terms of multi-functional integration, existing products often only provide a simple inflation interface, lacking multi-output control and mode switching functions for different loads (such as large-capacity air tanks, high-pressure tires, and pneumatic tools), making it difficult to meet the diverse air supply needs of general-purpose vehicles in emergency and routine maintenance. Therefore, developing a general-purpose vehicle emergency air supply module that integrates intelligent pressure control, historical data self-learning, fault diagnosis, and multi-functional output is of great significance for improving vehicle emergency self-rescue capabilities and routine maintenance efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a general-purpose vehicle emergency auxiliary air supply system to solve the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following solution: This invention provides a general vehicle emergency auxiliary air supply system, comprising: An air compression unit, which is a miniature air compressor driven by a DC motor, is used to generate compressed air; An air storage unit, which is a high-pressure air storage tank, is connected to the air outlet of the air compression unit and is used to store the compressed air. A pressure detection unit, comprising at least one pressure sensor, wherein the pressure sensor is disposed in the output gas path of the gas storage unit, for real-time detection of gas pressure and generation of pressure signal; The control unit is electrically connected to the air compression unit and the pressure detection unit. The control unit includes a processor and a memory. The memory stores computer instructions and historical inflation data. The processor executes the computer instructions to control the start or stop of the air compression unit. The historical inflation data stored in the control unit's memory includes multiple sets of inflation records. Each set of inflation records includes at least the starting pressure at the start of inflation, the ending pressure at the end of inflation, the inflation duration, the accuracy parameters of the pressure sensor in the pressure detection unit, and the stopping pressure when inflation actually stops. The control unit is also configured to determine whether an air leak has occurred in the air path based on the pressure values ​​detected by the pressure detection unit at at least two different time points after the air compression unit stops working, and to generate an alarm signal when a leak is detected. The control unit is also configured to dynamically set a leakage threshold based on the actual volume of the air storage unit. Furthermore, the control unit is configured to predict and output the remaining inflation time during inflation based on the current pressure of the air storage unit, the target pressure, and the average output flow rate of the air compression unit. An output interface unit, which is connected to the gas storage unit, includes at least one quick-connect connector for connecting an external device to be filled.

[0006] Preferably, the DC motor is powered by a voltage of 24V.

[0007] Preferably, the storage pressure of the high-pressure gas storage tank is greater than or equal to 900 kPa.

[0008] Preferably, it further includes a pressure gauge, which is installed in the output gas path of the gas storage unit.

[0009] Preferably, it further includes a mode selection switch, which is electrically connected to the control unit and is used to select multiple working modes, including at least: tire inflation mode, vehicle air tank inflation mode, and pneumatic tool air supply mode; the control unit retrieves a preset pressure range corresponding to the working mode selected by the mode selection switch from the memory.

[0010] Preferably, the output interface unit further includes a multi-way valve group, which is controlled by the control unit and is used to selectively distribute the compressed air in the air storage unit to one or more of the quick-connect couplings.

[0011] Preferably, the air compression unit, air storage unit, pressure detection unit, control unit, and output interface unit are integrated and installed in a portable frame, which is provided with a power interface for connecting to an external vehicle power supply.

[0012] The present invention also provides a method for controlling the inflation of an emergency auxiliary air supply system for general-purpose vehicles, comprising the following steps: S1. In response to the inflation start command, the current inflation pressure is obtained in real time through the pressure detection unit; S2. Read multiple historical inflation data for the same inflation device from the memory; S3. Input the multiple historical inflation data into a preset pressure compensation model to calculate the target stopping pressure for this inflation. The pressure compensation model is constructed based on a machine learning algorithm. Its input parameters include the starting pressure, ending pressure, inflation time, sensor accuracy, and stopping pressure in the historical inflation data. The output is the compensated target stopping pressure. S4. Compare the current inflation pressure with the target stop pressure in real time; S5. When the current inflation pressure reaches the target stop pressure, control the air compression unit to stop working, and store the inflation data of this inflation process as a new inflation record in the memory to update the historical inflation data.

[0013] Preferably, it also includes a leak self-diagnosis step: After the air compression unit stops working, the pressure detection unit acquires the data at the first time point. The first pressure value detected and at the second time point The second pressure value detected The rate of change of pressure per unit time is calculated using the following formula: ; If the absolute value of the pressure change rate is greater than a preset leakage threshold, it is determined that a gas leak has occurred, and an alarm signal is generated.

[0014] Preferably, the leakage threshold is dynamically set using the following formula: ; in, Based on the basic leakage threshold, This refers to the actual volume of the gas storage unit. For reference volume, This is a preset adjustment coefficient.

[0015] The present invention achieves the following beneficial technical effects compared to the prior art: This invention provides a universal vehicle emergency auxiliary air supply system. By integrating an air compression unit, an air storage unit, a pressure detection unit, a control unit, and an output interface unit, it forms a compact and fully functional emergency air supply system. Utilizing historical inflation data stored in the control unit, combined with a pressure compensation model based on machine learning algorithms, the system can dynamically calculate a more accurate target stopping pressure based on data accumulated during multiple inflations of the same device, such as starting pressure, ending pressure, inflation time, and sensor accuracy. This effectively offsets measurement errors caused by low-cost pressure sensors, ensuring that each inflation accurately reaches the user's desired pressure value, significantly improving inflation quality and safety. Simultaneously, through a leak self-diagnosis logic, the system automatically detects the rate of change in air circuit pressure after inflation stops and compares it with a leak threshold dynamically set according to the air storage unit volume. This timely and accurate identification of leak faults and alarms prevent energy waste and equipment damage caused by ineffective air compressor operation. In addition, the system's built-in mode selection switch and multi-way valve group enable it to flexibly switch between various working modes such as tire, air tank, and pneumatic tools. Through integrated design, it achieves portability and plug-and-play functionality. Drivers can easily operate it using the original vehicle battery. It effectively solves various emergency problems such as vehicles being unable to start the parking brake due to insufficient air pressure, tire leaks in the wild, and temporary air extraction for pneumatic tools. It also extends to routine maintenance applications such as painting and dust removal, greatly improving the vehicle's emergency self-rescue capabilities and overall protection efficiency.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The purpose of this invention is to provide a general vehicle emergency auxiliary air supply system to solve the technical problems of low control accuracy, lack of adaptive capability and fault diagnosis function of portable air filling equipment in the prior art, and difficulty in meeting diverse air demand.

[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: Figure 1 This is a schematic diagram of a general-purpose vehicle emergency auxiliary air supply system provided by the present invention. Figure 1 As shown, this invention provides a universal vehicle emergency auxiliary air supply system, including an air compression unit, an air storage unit, a pressure detection unit, a control unit, and an output interface unit. The air compression unit is a miniature air compressor driven by a DC motor, used to generate compressed air. In a preferred embodiment, the DC motor is powered by 24V, allowing direct connection to the vehicle battery for power, eliminating the need for additional power equipment, making it particularly suitable for field emergency scenarios. The air storage unit is a high-pressure air tank connected to the outlet of the air compression unit, used to store the compressed air generated by the air compression unit. In a preferred embodiment, the high-pressure air tank is designed to have a storage pressure greater than or equal to 900kPa, which can meet the air pressure requirements of most vehicle tires, air cylinders, and pneumatic tools.

[0024] The pressure detection unit includes at least one pressure sensor, which is installed in the output gas path of the gas storage unit to detect the gas pressure in the output gas path in real time and generate a corresponding pressure signal. In this embodiment, the pressure sensor uses an industrial-grade pressure sensing element. Although a medium-precision level is selected to control costs, high-precision pressure control can still be achieved through algorithm compensation by the subsequent control unit. To further facilitate intuitive observation by the user, as another preferred embodiment, the system may also include a pressure gauge, which is also installed in the output gas path of the gas storage unit to mechanically display the current pressure, serving as a redundant backup for electronic detection.

[0025] The control unit is the core component for achieving intelligent control in this invention. It is electrically connected to the air compression unit and the pressure detection unit. Specifically, the control unit includes a processor and a memory. The memory stores computer instructions and historical inflation data. The processor executes these computer instructions to control the start or stop of the air compression unit. In this embodiment, the construction of historical inflation data plays a crucial role. The historical inflation data stored in the memory includes multiple sets of inflation records. Each set of inflation records contains at least the following information: the initial pressure at the start of inflation, the termination pressure at the end of inflation, the inflation duration of the current inflation process, the accuracy parameters of the pressure sensor in the pressure detection unit, and the actual stopping pressure when inflation stops during the current inflation process. This data provides the foundation for subsequent pressure compensation and adaptive learning.

[0026] The control unit is also equipped with several intelligent functions. First, after the air compressor unit stops operating, the control unit determines whether a leak has occurred in the air path based on the pressure values ​​detected by the pressure detection unit at at least two different time points, and generates an alarm signal if a leak is detected. Specifically, the control unit obtains the pressure values ​​detected by the pressure detection unit at the first time point... The first pressure value detected and at the second time point The second pressure value detected ; The formula for calculating the rate of change of pressure per unit time is: ; If the absolute value of the pressure change rate exceeds a preset leakage threshold, a gas leak is detected, and an alarm signal is generated, prompting the user to check the interface connection or the integrity of the gas path. Secondly, considering that different types of gas storage units have different volumes, using a fixed leakage threshold might lead to minor leaks in large-volume gas tanks being overlooked, or temperature fluctuations in small-volume gas tanks being misjudged as leaks. Therefore, the control unit is also configured to dynamically set this leakage threshold based on the actual volume of the gas storage unit. Specifically, the leakage threshold is dynamically set using the following formula: ; in, Based on the basic leakage threshold, This refers to the actual volume of the gas storage unit. For reference volume, This is a preset adjustment coefficient. By introducing a volume correction term, the formula enables the leak detection threshold to adapt to different specifications of gas storage tanks, avoiding false or false detections due to volume differences, and improving the accuracy and reliability of fault diagnosis.

[0027] In addition, the control unit is configured to predict and output the remaining inflation time during the inflation process based on the current pressure of the air storage unit, the target pressure, and the average output flow rate of the air compression unit. This function, although not explicitly stated in... Figure 1 While shown separately, its implementation relies on the processor's statistical analysis and real-time calculation of historical inflation data in memory, providing users with a clear expectation of waiting time and improving the user experience.

[0028] The output interface unit communicates with the air storage unit and includes at least one quick-connect fitting for connecting an external device to be inflated. In a preferred embodiment, the system also includes a mode selection switch electrically connected to the control unit for selecting multiple operating modes. These operating modes include at least: tire inflation mode, vehicle air tank inflation mode, and pneumatic tool air supply mode. The control unit retrieves a preset pressure range corresponding to the selected operating mode from its memory to ensure safe and efficient inflation under different loads. To further expand functionality, the output interface unit also includes a multi-way valve assembly controlled by the control unit for selectively distributing compressed air from the air storage unit to one or more of the quick-connect fittings. This allows the system to connect multiple devices to be inflated simultaneously or to quickly switch between different devices without repeatedly plugging and unplugging fittings.

[0029] To achieve portability and plug-and-play functionality, the air compression unit, air storage unit, pressure detection unit, control unit, and output interface unit are integrated into a portable frame, which includes a power interface for connecting to an external vehicle power source. This integrated design makes the entire system small and lightweight, easy to carry in a vehicle, and can be operated independently by the driver in emergencies without the need for specialized tools or an additional power source.

[0030] Example 2: The present invention also provides a charging control method for the aforementioned general vehicle emergency auxiliary air supply system, which is implemented by a processor in a control unit executing computer instructions stored in a memory. The method includes the following steps: The first step is to respond to the inflation start command by acquiring the current inflation pressure in real time through the pressure detection unit. The inflation start command can be triggered by the user through a mode selection switch or a separate start button. The system then enters the inflation working state, and the pressure sensor begins to continuously monitor the pressure value of the output air path.

[0031] The second step involves reading multiple historical inflation data sets for the same device to be inflated from the memory. Identification of the "same device to be inflated" can be achieved either by the user manually selecting the mode and confirming the device type, or by creating independent data storage areas for different devices in the memory. The read historical inflation data includes multiple sets of inflation records, each containing information such as starting pressure, ending pressure, inflation duration, sensor accuracy, and stopping pressure.

[0032] The third step involves inputting multiple historical inflation data points into a pre-defined pressure compensation model to calculate the target stopping pressure for the current inflation. This pressure compensation model is built based on machine learning algorithms, specifically backpropagation (BP) neural networks. The model's input parameters include the starting pressure, ending pressure, inflation duration, sensor accuracy, and stopping pressure from the historical inflation data. The output is the compensated target stopping pressure. In practical applications, the BP neural network uses an error backpropagation algorithm to dynamically adjust the weight matrix of each layer based on the difference between the actual stopping pressure after each inflation and the pre-defined standard pressure, thereby optimizing the calculation accuracy of the target stopping pressure for subsequent inflations. As the number of inflations increases, the accumulated historical data becomes more abundant, the model's compensation effect improves, and the calculation of the target stopping pressure becomes more accurate, effectively offsetting the measurement errors caused by the low-cost pressure sensor.

[0033] The fourth step involves real-time comparison between the current inflation pressure and the target stopping pressure. The control unit continuously compares the pressure values ​​detected by the pressure sensor in real time with the target stopping pressure calculated in the third step.

[0034] Fifth, when the current inflation pressure reaches the target stop pressure, the air compression unit is controlled to stop working, and the inflation data during this inflation process is stored in the memory as a new inflation record, updating the historical inflation data. This step achieves closed-loop data updates, expanding the historical database after each inflation and providing more samples for pressure compensation in the next inflation, forming a virtuous cycle of self-learning and self-optimization.

[0035] In a preferred embodiment, the inflation control method of the present invention further includes a leak self-diagnosis step. This step is executed after the air compression unit stops working, specifically: acquiring a first pressure value detected by the pressure detection unit at a first time point and a second pressure value detected at a second time point; then calculating the pressure change rate per unit time according to the aforementioned formula; if the absolute value of the pressure change rate is greater than a preset leak threshold, it is determined that a leak has occurred in the air circuit, and an alarm signal is generated. The setting of the leak threshold has been detailed above and will not be repeated here. Through this self-diagnosis step, the system can promptly detect and prompt the user to handle leak problems, avoiding ineffective operation of the air compressor and energy waste caused by leaks, while also protecting the equipment from damage caused by prolonged idling.

[0036] In summary, the universal vehicle emergency auxiliary air supply system and its control method provided by this invention achieve high precision, adaptability, and multi-functionality through integrated optimization of hardware structure and innovative design of control algorithms. This system not only solves the problems of low control precision and lack of fault diagnosis capabilities in existing air filling equipment, but also meets the diverse needs of vehicle emergency scenarios through mode switching and multi-output, demonstrating significant technological advancement and practical value.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
