Description

Technical Field

[0001] This invention relates to the field of computer software protection technology, specifically to a method for implementing a compensation function that accurately detects the inflation pressure of a high-flow-rate air pump. Background Technology

[0002] Generally, car tires use DC air pumps powered by high-flow DC power to inflate them. To test the air pump's output and inflation pressure during each tire inflation process, the electronic device is connected to a sealed container's air circuit. The pump is then manually operated to inflate, deflate, and time the air flow into the sealed container. The test results are then determined based on manually recorded data, facilitating tire inflation during operation.

[0003] However, during manual testing, the manual timing using timers such as stopwatches can easily cause large errors, especially when manually controlling the air pump to release air and timing simultaneously. Since the release of air is an instantaneous event, the human reaction speed is much slower than the speed at which the release event occurs, resulting in a large timing error. As a result, the number of defective electronic devices obtained is higher than the actual number of defective electronic devices, which leads to low test accuracy and reduced test efficiency.

[0004] Furthermore, during the process of inflating car tires, it is necessary to compensate for the air pressure to avoid large pressure differences among the four tires. Summary of the Invention

[0005] This invention provides a method and system for accurately compensating for the inflation pressure of a high-flow-rate air pump. It facilitates detection and compensation during tire inflation, preventing large pressure deviations caused by significant errors and reducing pressure variations among different tires. This addresses the issues mentioned in the background section regarding manual testing, where stopwatches and other timers can easily introduce large errors, especially when manually controlling the air pump to deflate and simultaneously timing. Since deflation is an instantaneous event, human reaction time is much slower than the deflation event, leading to significant timing errors. This results in a higher number of faulty electronic devices than the actual number, leading to low test accuracy and reduced testing efficiency. Furthermore, the invention emphasizes the need for pressure compensation during tire inflation to prevent large pressure deviations among the four tires.

[0006] This invention provides the following technical solution: a high-flow-rate air pump inflation pressure detection system, including a processor, wherein the processor includes a detection module and a compensation module;

[0007] The detection module includes a sampling unit, a refill air path, and a circulation detector path, which samples and detects during the intermittent periods when the DC air pump supplies air to the tire;

[0008] The compensation module is used to provide appropriate compensation for pressure deviations during the operation of the DC air pump.

[0009] As an optional solution for the method of accurately compensating for the inflation pressure detection of a large flow air pump as described in this invention, the processor further includes an inflation module, a stop module, and a leakage rate module.

[0010] The inflation module is used to inflate the tire during the intermittent periods when the DC air pump inflates the tire, and detects the pressure value through a pressure detector inside the sealed container during the inflation process.

[0011] The stop module is used to calculate the static air pressure value during the stop process in the intermittent air pumping process.

[0012] The leakage rate module is used to obtain the leakage rate during intermittent inflation.

[0013] As an optional solution for the method of realizing accurate compensation function of high flow air pump inflation pressure detection described in this invention, the compensation module includes a gas temperature difference compensation unit and a dynamic gas compensation compensation unit.

[0014] The gas temperature difference compensation unit can be calculated using the following flow rate equation:

[0015]

[0016] In the formula: q represents the volumetric flow rate of the gas being measured under operating conditions;

[0017] ρ represents the density of the gas being measured under operating conditions;

[0018] ΔP represents differential pressure;

[0019] K represents a coefficient, which includes the flow coefficient, expansion coefficient, pipe aperture coefficient, and temperature difference influence coefficient.

[0020] As an optional solution for the method of accurate compensation function for high-flow air pump inflation pressure detection described in this invention, the processor further includes a dynamic scanning module;

[0021] The dynamic scanning module is used to form a display page through LED digital tubes, and uses 3+9 IOs for time-division scanning to obtain the calibration air pressure value and linear compensation value.

[0022] As an optional solution for the method of accurate compensation function for high-flow air pump inflation pressure detection described in this invention, the detection module uses a pressure detector, which is used to detect the intermittent pressure value inside the container and store the pressure value.

[0023] The compensation module uses a pressure compensation regulator;

[0024] The air pump is connected to the sealed container, and the sealed container is electrically connected to the sampling unit, the refill air path, and the circulation detector path. The compensation regulator is electrically connected to the air pump.

[0025] A method for compensating the inflation pressure of a high-flow-rate air pump, wherein the compensation method is implemented through a dynamic air compensation unit, and includes the following steps:

[0026] S1. Accurate pressure is obtained based on static energy: At this time, the air pump is not pumping air and there is no flow difference in the pipe, so the product can accurately display the actual tire pressure.

[0027] S2, dynamic pressure detection and calculation of dynamic pressure difference;

[0028] S3, based on the dynamic air pressure difference, outputs pressure by using a pressure compensation regulator to adjust the air pump's air pressure difference.

[0029] As an optional solution for the method of accurately compensating for the inflation pressure detection of a large-flow air pump as described in this invention, the calculation of the dynamic air pressure difference is obtained through the following steps;

[0030] When the air pump is in motion, that is, during air pumping, the method of pumping for a period of time, pausing for 1 second, then pumping for a period of time, pausing for 1 second, and repeating this cycle is used.

[0031] Each time the tire stops, record the static tire pressure value a0 (a1, a2, a3, ..., an) at the moment of stopping. The difference between two adjacent static values ​​is the increase in tire pressure during this inflation period. In this way, a value b0 (b1, b2, b3, ..., bn) can be calculated as an average change over time during this period.

[0032] The expression for converting dynamic barometric pressure display values ​​is:

[0033] y = a n +b n-1

[0034] When the air pump starts pumping air, the dynamic air compensation unit will default to providing an average change value 'b'. After one stop-pump cycle, it will follow the formula y=a. n +b n-1 The formula calculates and displays the value;

[0035] Since the average change value given by the product at the beginning of each inflation is not applicable to every tire (due to size differences), the first inflation time will be 10 seconds. If the actual tire pressure is greater than 10 PSI after inflation, the inflation time for the second and subsequent inflations will be set to 40 seconds. If the actual tire pressure is less than 10 PSI after inflation, the inflation time will continue for 10 seconds until it exceeds 10 PSI.

[0036] As an optional solution for the method of accurately detecting the inflation pressure of a high-flow-rate air pump as described in this invention, the processor of the compensation module is used to execute the compensation method as described in claims 6-7 during the compensation method steps.

[0037] As an optional solution for the method of accurate compensation function for high-flow air pump inflation pressure detection described in this invention, the processor is used to perform air pump inflation pressure detection as described in claims 1 to 5 during the detection process of the detection system.

[0038] The present invention has the following beneficial effects:

[0039] 1. This invention relates to a method for accurately compensating for inflation pressure detection in a high-flow air pump. The detection module in the processor samples and detects the return air path and the circulation detection air path of the DC air pump during intermittent periods to obtain the airflow pressure value. By obtaining the intermittent air pump pressure value and the pressure difference during the intermittent inflation process, the static air pressure value and the difference between the active air pressure value are calculated, as well as the leakage rate. These coefficient values ​​are then used to achieve pressure compensation, which facilitates detection and compensation during tire inflation, avoids large errors that lead to large air pressure deviations, and reduces the situation of large pressure deviations between different tires of a car.

[0040] 2. The method for achieving accurate compensation function of high-flow air pump inflation pressure detection is achieved by using a gas temperature difference compensation unit. When the gas temperature difference is large, the gas value to be compensated can be calculated by an equation, which facilitates gas temperature difference compensation and reduces the large pressure deviation of the air pump caused by temperature difference.

[0041] 3. The method for implementing accurate compensation function for high-flow air pump inflation pressure detection: When the air pump starts pumping, the dynamic air compensation unit will default to providing an average change value 'b'. After one stop-and-pump cycle, it will adjust according to y=a... n +b n-1 The formula calculates and displays an average value for each inflation process, which helps to compensate for pressure deviations during tire inflation and ensures a more consistent inflation pressure.

[0044] 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.

[0045] Example 1

[0046] Generally, car tires use DC air pumps powered by high-flow DC power to inflate them. To test the air pump's output and inflation pressure during each tire inflation process, the electronic device is connected to a sealed container's air circuit. The pump is then manually operated to inflate, deflate, and time the air flow into the sealed container. The test results are then determined based on manually recorded data, facilitating tire inflation during operation.

[0047] However, during manual testing, the manual timing using timers such as stopwatches can easily cause large errors, especially when manually controlling the air pump to release air and timing simultaneously. Since the release of air is an instantaneous event, the human reaction speed is much slower than the speed at which the release event occurs, resulting in a large timing error. As a result, the number of defective electronic devices obtained is higher than the actual number of defective electronic devices, which leads to low test accuracy and reduced test efficiency.

[0048] Furthermore, during the process of inflating car tires, it is necessary to compensate for the air pressure to avoid large pressure differences among the four tires.

[0049] This invention provides the following technical solution: a high-flow-rate air pump inflation pressure detection system, please refer to... Figure 1 - Figure 2 The processor includes a detection module and a compensation module.

[0051] The compensation module is used to provide appropriate compensation for pressure deviations during the operation of the DC air pump.

[0052] The processor further includes an air pumping module, a stop module, and a leakage rate module.

[0053] The inflation module is used to inflate the tire during the intermittent periods when the DC air pump inflates the tire, and detects the pressure value through a pressure detector inside the sealed container during the inflation process.

[0054] The stop module is used to calculate the static air pressure value during the stop process in the intermittent air pumping process.

[0055] The leakage rate module is used to obtain the leakage rate during intermittent inflation.

[0056] In this embodiment, the detection module in the processor samples and detects the return air path and circulation detection air path of the DC air pump during intermittent periods to obtain the airflow pressure value. During the intermittent inflation process, the intermittent air pump pressure value is obtained, the pressure difference is obtained, the static air pressure value and the difference between the active pressure value are calculated, and the leakage rate is calculated. Then, the pressure compensation method is realized by detecting these coefficient values ​​through pressure detection. This method facilitates detection and compensation during the tire inflation process, avoids large errors that lead to large air pressure deviations, and reduces the situation of large pressure deviations between different tires of a car.

[0058] This embodiment is an improvement upon Embodiment 1. For details, please refer to [link / reference]. Figure 1 - Figure 2 The compensation module includes a gas temperature difference compensation unit and a dynamic gas compensation unit.

[0059] The gas temperature difference compensation unit can be calculated using the following flow rate equation:

[0060]

[0061] In the formula: q represents the volumetric flow rate of the gas being measured under operating conditions;

[0062] ρ represents the density of the gas being measured under operating conditions;

[0063] ΔP represents differential pressure;

[0064] K represents a coefficient, which includes the flow coefficient, expansion coefficient, pipe aperture coefficient, and temperature difference influence coefficient.

[0065] In this embodiment, the gas temperature difference compensation unit can calculate the gas value to be compensated by an equation when the gas temperature difference is large, which facilitates the compensation of gas temperature difference.

[0068] The dynamic scanning module is used to form a display page through LED digital tubes, and uses 3+9 IOs for time-division scanning to obtain the calibration air pressure value and linear compensation value.

[0069] The detection module uses a pressure detector, which is used to detect intermittent pressure values ​​inside the container and store the pressure values.

[0070] The compensation module uses a pressure compensation regulator;

[0071] The air pump is connected to the air circuit of the sealed container, and the sealed container is electrically connected to the sampling unit, the refill air circuit, and the circulation detector circuit. The compensation regulator is electrically connected to the air pump.

[0072] In this embodiment, the standard air pressure value and linear compensation value are obtained through the dynamic scanning module, which makes it easier for the display page to show the linear compensation status, allowing staff to make a more intuitive judgment through the display.

[0078] Wherein: the dynamic pressure difference value is obtained through the following steps;

[0079] When the air pump is in motion, that is, during air pumping, the method of pumping for a period of time, pausing for 1 second, then pumping for a period of time, pausing for 1 second, and repeating this cycle is used.

[0080] Each time the tire stops, record the static tire pressure value a0 (a1, a2, a3, ..., an) at the moment of stopping. The difference between two adjacent static values ​​is the increase in tire pressure during this inflation period. In this way, a value b0 (b1, b2, b3, ..., bn) can be calculated as an average change over time during this period.

[0081] The expression for converting dynamic barometric pressure display values ​​is:

[0082] y = an +b n-1

[0084] Since the average change value given by the product at the beginning of each inflation is not applicable to every tire (due to size differences), the first inflation time will be 10 seconds. If the actual tire pressure is greater than 10 PSI after inflation, the inflation time for the second and subsequent inflations will be set to 40 seconds. If the actual tire pressure is less than 10 PSI after inflation, the inflation time will continue for 10 seconds until it exceeds 10 PSI.

After one stop-pump cycle, it will follow the formula y=a. n +b n-1 The formula calculates and displays an average value for each inflation process, which helps to compensate for pressure deviations during tire inflation and ensures a more consistent inflation pressure.
