[0010] In a possible implementation, the deflating the inflating and deflating device according to the first initial air pressure to obtain the current deflating efficiency of the inflating and deflating device includes: deflating the inflating and deflating device when the air pressure inside the inflating and deflating device is the first initial air pressure; obtaining a second deflating air pressure inside the inflating and deflating device when the deflating time length of the inflating and deflating device is a preset second deflating time length; and determining the current deflating efficiency of the inflating and deflating device according to the second deflating time length and the second deflating air pressure.

Further, the control device can perform gas charging and discharging on the gas charging and discharging device to adjust the current gas charging and discharging efficiency of the gas charging and discharging device, so that the adjusted current gas charging and discharging efficiency belongs to the expected gas charging and discharging efficiency range, and then the volume of the gas charging and discharging device is controlled within a reasonable range, so as to avoid the volume of the gas charging and discharging device being too large or too small, and ensure the normal operation of the gas charging and discharging device.

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0030] The following will be described in detail respectively.

[0031] The terms “first”, “second”, “third”, and “fourth” and the like in the description, claims, and drawings of the present application are used to distinguish different objects, and are not used to describe a particular order. In addition, the terms “include” and “have” and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device including a series of steps or modules is not limited to the listed steps or modules, but can optionally include steps or modules not listed, or can optionally include other steps or modules inherent to the process, method, product, or device.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] It should be understood that a deflation device refers to a device with deflation functions. For example, in some applications, a deflation device can be an air pump in a vehicle. The vehicle can use a motor to inflate the air pump, which then stores the inflated gas. The vehicle can also use a solenoid valve to deflate the air pump, providing the stored gas to the vehicle's air-using devices. Simultaneously, it can release excess gas from the pump, preventing excessive pressure buildup inside the deflation device.

[0034] In some feasible implementations, the inflation / deflation device may include a variable-volume inflation / deflation device or a fixed-volume container. When the inflation / deflation device is a variable-volume device, its shell can deform, allowing the volume of the device to change. Conversely, when the inflation / deflation device is a fixed-volume container, its shell cannot deform, thus its volume remains unchanged.

[0035] It should be noted that the control method provided in this application can be applied to scenarios where the inflation / deflation device is the aforementioned variable volume inflation / deflation device. For ease of understanding, the inflation / deflation device described in the following content will be referred to as a variable volume inflation / deflation device, i.e., it will be described as an inflation / deflation device for short.

[0036] In some feasible implementations, embodiments of this application can use an external motor and solenoid valve to charge and deflate the gas charging and deflation device. The charging and deflation device can store the charged gas or supply the stored gas to external gas-consuming devices. For details, please refer to... Figure 1 , Figure 1 This is a schematic diagram of the inflation / deflation device provided in an embodiment of this application. Figure 1 As shown, the inflation / deflation device is connected to an external motor and solenoid valve. The motor can charge the device with gas, and the solenoid valve can release gas from the device, thus performing the inflation / deflation process. The device can also be connected to external gas-consuming equipment and supply gas to that equipment. Furthermore, as... Figure 1As shown, the embodiment of the present application can also detect the air pressure inside the gas charging and discharging device through the air pressure sensor, and detect the bearing pressure of the gas charging and discharging device shell through the pressure sensor. The bearing pressure of the gas charging and discharging device shell can be understood as the resultant force formed by the pressure difference between the air pressure (external air pressure) of the working environment of the gas charging and discharging device and the internal air pressure on the shell. That is, the difference between the pressure of the external air pressure acting on the shell of the gas charging and discharging device and the pressure of the internal air pressure acting on the shell of the gas charging and discharging device is the bearing pressure of the shell of the gas charging and discharging device.

[0037] It can be understood that, in the process of charging the gas charging and discharging device by the motor, as the amount of gas inside the gas charging and discharging device increases, the air pressure inside the gas charging and discharging device can be detected by the air pressure sensor to increase, and at the same time, the bearing pressure of the gas charging and discharging device shell can be detected by the pressure sensor to increase. Since the gas charging and discharging device is a variable-volume gas charging and discharging device, when the bearing pressure of the gas charging and discharging device gradually increases, the volume of the gas charging and discharging device also gradually increases. The deformation amount (i.e. the change amount of the volume) of the shell of the gas charging and discharging device is limited, so when the deformation amount of the shell of the gas charging and discharging device reaches the maximum deformation amount, the volume of the gas charging and discharging device no longer increases and remains a fixed volume. That is, as the amount of gas charged in the gas charging and discharging device increases, the bearing pressure of the gas charging and discharging device gradually increases, and the volume of the gas charging and discharging device gradually increases until it is maintained in a maximum volume state.

[0038] In some possible embodiments, in order to ensure stable storage of gas, the amount of gas stored inside the gas charging and discharging device should not exceed the rated maximum amount of the device. Specifically, when excessive gas is charged, since the gas charging and discharging device is a variable-volume gas charging and discharging device, the air pressure inside the gas charging and discharging device rises too much, which can cause excessive deformation of the shell of the gas charging and discharging device, and even irreversible deformation, affecting the stability of the gas charging and discharging device. At the same time, when the shell of the gas charging and discharging device is excessively deformed, the irreversible damage will occur at each joint (such as the joint of the gas charging pipeline and the device body) of the shell of the gas charging and discharging device, which will further adversely affect the air tightness of the gas charging and discharging device and reduce the service life of the gas charging and discharging device.

[0039] In some possible implementation manners, in order to ensure the gas supply efficiency of the gas charging and discharging device, the gas stored in the gas charging and discharging device is not less than a stable storage amount of the gas charging and discharging device. Specifically, the stable storage amount of the gas charging and discharging device can be understood as a rated value of the gas storage amount of the gas charging and discharging device, and when the gas charging and discharging device stores the stable storage amount of the gas, it means that the gas supply efficiency and the air tightness of the gas charging and discharging device are in the best state. The gas supply efficiency of the gas charging and discharging device can be understood as the amount of gas that the gas charging and discharging device can provide to an external gas using device in a unit of time. The gas supply efficiency of the gas charging and discharging device is related to the amount of gas stored in the gas charging and discharging device. When the amount of gas stored in the gas charging and discharging device is greater, the gas pressure in the gas charging and discharging device is greater, the volume of the gas charging and discharging device is greater, and the gas supply efficiency of the gas charging and discharging device is higher. Conversely, when the amount of gas stored in the gas charging and discharging device is smaller, the gas pressure in the gas charging and discharging device is smaller, the volume of the gas charging and discharging device is greater, and the gas supply efficiency of the gas charging and discharging device is lower.

[0040] Generally, when the volume of the gas charging and discharging device is too large, the excessive deformation of the shell affects the air tightness of the gas charging and discharging device, thereby reducing the service life of the gas charging and discharging device. When the volume of the gas charging and discharging device is too small, the amount of gas stored in the gas charging and discharging device is insufficient, and the insufficient amount of stored gas affects the gas supply efficiency of the gas charging and discharging device.

[0041] To solve the above problems, the embodiment of the present application provides a control method of a gas charging and discharging device, which can maintain the volume of the gas charging and discharging device within a reasonable range, ensure the air tightness and the gas supply efficiency of the gas charging and discharging device, and prolong the service life of the gas charging and discharging device.

[0042] The control method of the gas charging and discharging device provided by the embodiment of the present application is applicable to real-time detection and control of the current gas charging and discharging efficiency of the gas charging and discharging device, which is specifically described by the following embodiments. Figure 2 , Figure 2 A system architecture schematic diagram is provided for the embodiment of the present application. As shown in Figure 2 , the system architecture can include a gas charging and discharging device and a control device. The control device can be a smart terminal device such as a palm computer, a smart phone, a notebook computer, a desktop computer, a tablet computer, a mobile Internet device, a smart computer, a smart vehicle, but is not limited thereto.

[0043] It can be understood that the control method of the gas charging and discharging device provided by the embodiment of the present application can be executed by the control device as shown in Figure 2 . Specifically, Figure 2The control device shown can detect and control the current inflation / deflation efficiency of the inflation / deflation equipment in real time. For example, when the pressure difference between the inside and outside of the inflation / deflation equipment changes, causing a change in the volume of the equipment, the control device can detect whether the current inflation / deflation efficiency is within the desired range. If the current efficiency is not within the desired range, the control device will adjust the efficiency to ensure it falls within the desired range, thus keeping the volume of the equipment within a reasonable range.

[0044] For further details, please refer to Figure 3 , Figure 3 This is a schematic flowchart illustrating a control method for a gas filling / discharging device provided in an embodiment of this application. For ease of understanding, this embodiment uses the aforementioned control device as an example for explanation; that is, each step of the control method provided in this embodiment can be... Figure 2 The control device shown is used to perform the operation, such as Figure 3 As shown, the control method may include at least the following steps S101-S102.

[0045] Step S101: When a change in the volume of the inflation / deflation device is detected, the inflation / deflation device is inflated or deflated to obtain the current inflation / deflation efficiency of the inflation / deflation device.

[0046] In some feasible implementations, the current inflation / deflation efficiency of the inflation / deflation device refers to the inflation / deflation efficiency corresponding to the device in its current volume state. Specifically, the inflation / deflation efficiency refers to the change in internal air pressure of the inflation / deflation device per unit time during inflation / deflation. It can be understood that a higher current inflation / deflation efficiency indicates a greater change in internal air pressure per unit time during inflation / deflation, and vice versa.

[0047] It should be explained that when the inflation / deflation device is a volume-variable inflation / deflation device, the current inflation / deflation efficiency is related to the volume of the device. The larger the volume of the device, the lower the corresponding current inflation / deflation efficiency, and vice versa.

[0048] In some application scenarios, the current inflation / deflation efficiency of the inflation / deflation device is related to the pressure difference between the external environment pressure and the internal pressure of the inflation / deflation device. When the external environment pressure or the internal pressure of the inflation / deflation device changes, the pressure difference between the internal and external of the inflation / deflation device (i.e., the pressure difference between the external environment pressure and the internal pressure) changes. Further, the resultant force of the pressure difference between the internal and external of the inflation / deflation device on the shell changes the volume of the inflation / deflation device. As known from the above, the volume of the inflation / deflation device is related to the current inflation / deflation efficiency of the inflation / deflation device. Therefore, when the volume of the inflation / deflation device changes due to the change of the pressure difference between the internal and external of the inflation / deflation device, the current inflation / deflation efficiency of the inflation / deflation device is also affected by the change of the pressure difference between the internal and external of the inflation / deflation device. Therefore, the current inflation / deflation efficiency of the inflation / deflation device can be used as the contact point of the two variables of the external environment pressure and the internal pressure, and when the volume of the inflation / deflation device changes due to the changes of the external environment pressure and the internal pressure, the current inflation / deflation efficiency of the inflation / deflation device is detected and controlled to adjust the volume of the inflation / deflation device.

[0049] For example, when the vehicle enters a high-altitude area, the external environment pressure of the inflation / deflation device (e.g., the air pump) of the vehicle decreases due to the decrease of the atmospheric pressure in the high-altitude area. At the same time, if the inflation / deflation device supplies gas to the gas-consuming device, the decrease of the internal gas also decreases the internal pressure of the inflation / deflation device, that is, the external environment pressure and the internal pressure of the inflation / deflation device change. Since the pressure difference between the external environment pressure and the internal pressure of the inflation / deflation device affects the volume of the inflation / deflation device, and further affects the current inflation / deflation efficiency of the inflation / deflation device. Therefore, the control device of the embodiment of the present application can detect the current inflation / deflation efficiency of the inflation / deflation device, and adjust the current inflation / deflation efficiency of the inflation / deflation device when the external environment pressure and the internal pressure of the inflation / deflation device change, so that the current inflation / deflation efficiency of the inflation / deflation device is not too large or too small, and further the volume of the inflation / deflation device is maintained within a reasonable range, that is, the volume of the inflation / deflation device is not too large or too small.

[0050] In summary, the control device in the embodiment of the present application can detect and control the current inflation / deflation efficiency of the inflation / deflation device by taking the current inflation / deflation efficiency of the inflation / deflation device as the contact point of the two variables of the external environment pressure and the internal pressure without identifying the external environment pressure. Further, the current inflation / deflation efficiency of the inflation / deflation device is adjusted when the current inflation / deflation efficiency of the inflation / deflation device is too large or too small, so as to adjust the volume of the inflation / deflation device.

[0051] In some possible implementations, as known from the above, the control device of the embodiment of the present application can determine the volume of the inflation / deflation device according to the current inflation / deflation efficiency of the inflation / deflation device by obtaining the current inflation / deflation efficiency of the inflation / deflation device. Specifically, please refer toFigure 4 , Figure 4 A pressure-time relationship diagram of the control method of the inflation and deflation equipment provided by the embodiment of the present application. As shown in Figure 4 , the inflation and deflation equipment can be inflated according to the time sequence from point A to point B. During the inflation process, the pressure change in the inflation and deflation equipment is shown in Figure 4 from point A to point B. First, when the inflation and deflation equipment is not inflated, the pressure P in the inflation and deflation equipment is 0 (corresponding to point A in Figure 4 ), at this time, the inflation and deflation equipment does not deform, that is, the volume of the inflation and deflation equipment does not change. Further, the inflation and deflation equipment is inflated from point A, and during the inflation process, the pressure P in the inflation and deflation equipment starts to increase and then decreases after reaching the maximum value Pmax. It can be understood that during the inflation process of the inflation and deflation equipment, the deformation amount of the inflation and deflation equipment increases, that is, the volume of the inflation and deflation equipment always increases. After the inflation of the inflation and deflation equipment for a period of time until the deformation amount of the inflation and deflation equipment reaches the maximum deformation amount (corresponding to point B in Figure 4 ), the volume of the inflation and deflation equipment maintains the maximum volume state (that is, the volume state corresponding to the maximum deformation amount) unchanged. As can be seen, during the inflation process from point A to point B, the pressure in the inflation and deflation equipment first increases and then decreases, while the deformation amount of the inflation and deflation equipment increases from 0 to the maximum deformation amount.

[0052] In some possible implementation manners, the inflation and deflation equipment can be deflated according to the time sequence from point B to point A, and during the deflation process, the pressure change in the inflation and deflation equipment is shown in Figure 4 from point B to point A. First, when the inflation and deflation equipment is not deflated, the pressure in the inflation and deflation equipment is P1 (corresponding to point B in Figure 4 ), at this time, the deformation amount of the inflation and deflation equipment reaches the maximum deformation amount, that is, the inflation and deflation equipment is in the maximum volume state. Further, the inflation and deflation equipment is deflated from point B, and during the deflation process, the pressure P1 in the inflation and deflation equipment starts to increase and then decreases after reaching the maximum value Pmax. It can be understood that during the deflation process of the inflation and deflation equipment, the deformation amount of the inflation and deflation equipment decreases, that is, the volume of the inflation and deflation equipment always decreases. After the deflation of the inflation and deflation equipment for a period of time until the deformation amount of the inflation and deflation equipment is 0 (corresponding to point A in Figure 4 ), that is, the inflation and deflation equipment does not deform. As can be seen, during the deflation process from point B to point A, the pressure in the inflation and deflation equipment first increases and then decreases, while the deformation amount of the inflation and deflation equipment decreases from the maximum deformation amount to 0.

[0053] In some feasible implementations, as can be seen from the above, during the inflation or deflation process of the inflation / deflation device, when the volumes of the inflation / deflation devices are different (corresponding to...) Figure 4 Different inflation times (T) correspond to different increases or decreases in air pressure. That is, different volumes of the inflation / deflation device correspond to different pressure changes. Therefore, the control device in this embodiment can determine the volume of the inflation / deflation device at a given moment based on its current inflation / deflation efficiency. Here, the current inflation / deflation efficiency can be understood as the pressure change within the inflation / deflation device per unit time during inflation / deflation.

[0054] For ease of understanding, the embodiments of this application are illustrated in the following examples. For example, as Figure 4 As shown, when the inflation / deflation device is inflated to point C1, let's assume the device's volume is V1. If inflation continues within a unit of time, the device's pressure increases. If deflation occurs within a unit of time, the device's pressure decreases. In other words, with a volume of V1, the change in internal pressure during inflation / deflation is greater than zero. Therefore, when the device's volume is V1, its current inflation / deflation efficiency is greater than zero.

[0055] For example, such as Figure 5 As shown, when the inflation / deflation device is inflated to point C2, assuming the volume of the device is V2, if inflation continues within a unit of time, the pressure inside the device decreases. If deflation occurs within a unit of time, the pressure inside the device increases. In other words, with a volume of V2, the change in internal pressure during inflation / deflation within a unit of time is less than 0. Therefore, when the volume of the device is V2, the current inflation / deflation efficiency is less than 0.

[0056] As can be understood from the above, when the volume of the inflation / deflation equipment is different, the current inflation / deflation efficiency of the corresponding equipment is also different, and the larger the volume of the inflation / deflation equipment, the lower the current inflation / deflation efficiency. Therefore, the embodiments of this application can determine the corresponding volume of the inflation / deflation equipment based on its current inflation / deflation efficiency when a change in the volume of the inflation / deflation equipment is detected, thereby detecting and controlling the volume of the inflation / deflation equipment, keeping it within a reasonable range, thus ensuring good airtightness and gas supply efficiency of the inflation / deflation equipment, and extending its service life.

[0057] In some feasible implementations, as can be seen from the above, the control device of this application embodiment can obtain the current inflation / deflation efficiency of the inflation / deflation device based on the internal pressure of the inflation / deflation device before adjustment (e.g., the second initial pressure), the inflation or deflation time of the inflation / deflation device, and the internal pressure of the inflation / deflation device after inflation / deflation. Therefore, the control device of this application embodiment can obtain the current inflation / deflation efficiency of the inflation / deflation device in the current volume state by first obtaining the internal pressure of the inflation / deflation device in the current volume state, and then inflating / deflation the inflation / deflation device based on the internal pressure.

[0058] For some feasible implementation methods, please refer to Figure 5 , Figure 5 This is another schematic flowchart illustrating the control method for the inflation / deflation device provided in an embodiment of this application. Figure 1 The control method shown includes at least the following steps S201-S203. In this embodiment, the current charging / discharging efficiency of the charging / discharging device is obtained through steps S201-S203. Further, the implementation of obtaining the current charging / discharging efficiency of the charging / discharging device may include the following steps:

[0059] Step S201: Obtain the first initial air pressure inside the inflation / deflation device.

[0060] Specifically, the control device in this application embodiment can detect the volume of the inflation / deflation device in real time, and when a change in the volume of the inflation / deflation device is detected, it can... Figure 6 The pressure sensor shown acquires the initial pressure inside the inflation / deflation device. This initial pressure can be understood as the internal pressure of the inflation / deflation device before any adjustments are made.

[0061] In some feasible implementations, as can be seen from the above, the control device of this application embodiment can charge or deflate the charging or deflation device when the internal air pressure of the charging or deflation device is the first initial air pressure, so as to obtain the current charging or deflation efficiency of the charging or deflation device.

[0062] In some feasible implementations, the current inflation / deflation efficiency of the inflation / deflation device can include both the current inflation efficiency and the current deflation efficiency. The current inflation efficiency of the inflation / deflation device can be understood as the pressure change after inflation per unit time for the device in its current volume state. The current deflation efficiency of the inflation / deflation device can be understood as the pressure change after deflation per unit time for the device in its current volume state. In other words, the control device in this application embodiment can determine the current inflation / deflation efficiency by acquiring the current inflation efficiency and the current deflation efficiency of the inflation / deflation device.

[0063] In step S202, the inflating and deflating equipment is inflated according to the first initial air pressure to obtain a current inflation efficiency of the inflating and deflating equipment.

[0064] In some possible embodiments, the control device of the present application can increase or decrease the internal air pressure of the inflating and deflating equipment from the first initial air pressure to a preset first inflation air pressure by inflating the inflating and deflating equipment to obtain the current inflation efficiency of the inflating and deflating equipment. Specifically, the control device of the present application can inflate the inflating and deflating equipment when the air pressure in the inflating and deflating equipment is equal to the first initial air pressure, and pause the inflation when the internal air pressure of the inflating and deflating equipment is detected by the air pressure sensor to change from the first initial air pressure to the preset first inflation air pressure. At the same time, the control device obtains a first inflation time length occupied by the change of the internal air pressure of the inflating and deflating equipment from the first initial air pressure to the first inflation air pressure. The first inflation air pressure can be understood as the internal air pressure of the inflating and deflating equipment after inflation, and the first inflation time length can be understood as the inflation time length of the inflating and deflating equipment from the first initial air pressure to the first inflation air pressure. It can be understood that the control device of the present application can determine the current inflation efficiency of the inflating and deflating equipment according to the first initial air pressure, the first inflation air pressure and the first inflation time length.

[0065] For ease of understanding, the present application is illustrated in the following content. Please refer to Figure 6 , Figure 6 Another air pressure-time relationship diagram of the control method of the inflating and deflating equipment provided by the present application is provided. The control device of the present application can obtain the internal air pressure of the inflating and deflating equipment as the first initial air pressure Pn1 by the air pressure sensor when the inflating and deflating equipment corresponds to the point Ay in Figure 6 Further, the control device inflates the inflating and deflating equipment when the internal air pressure of the inflating and deflating equipment is the first initial air pressure Pn1, and pauses the inflation when the internal air pressure of the inflating and deflating equipment is detected by the air pressure sensor to be equal to the preset first inflation air pressure Pn2, and determines that the inflation time length of the internal air pressure of the inflating and deflating equipment from the first initial air pressure Pn1 to the first inflation air pressure Pn2 is the first inflation time length t1, so that the current inflation efficiency of the inflating and deflating equipment at the point Ay can be obtained.

[0066] In some possible implementation manners, the control device of the embodiment of the present application can obtain the current inflation efficiency of the inflation and deflation device by inflating the inflation and deflation device for a preset second inflation duration. Specifically, the control device of the embodiment of the present application can inflate the inflation and deflation device when the internal air pressure of the inflation and deflation device is equal to the first initial air pressure, and suspend the inflation when the inflation duration is equal to the preset second inflation duration. Meanwhile, the control device detects the internal air pressure of the inflation and deflation device at this time as the second inflation air pressure through the air pressure sensor. The second inflation duration can be understood as the preset inflation duration of the inflation and deflation device, and the second inflation air pressure can be understood as the internal air pressure of the inflation and deflation device after the inflation for the second inflation duration. It can be understood that the control device of the embodiment of the present application can determine the current inflation efficiency of the inflation and deflation device according to the first initial air pressure, the second inflation air pressure and the second inflation duration.

[0067] For ease of understanding, the embodiment of the present application is illustrated in the following content. The control device of the embodiment of the present application can obtain the internal air pressure of the inflation and deflation device as the first initial air pressure Pn1 through the air pressure sensor. Further, the control device inflates the inflation and deflation device when the internal air pressure of the inflation and deflation device is the first initial air pressure Pn1, and suspends the inflation when the inflation duration is equal to the preset second inflation duration tc1. Meanwhile, the control device detects the internal air pressure of the inflation and deflation device at this time as the second inflation air pressure Pc1 through the air pressure sensor, and then the current inflation efficiency of the inflation and deflation device can be obtained.

[0068] In step S203, the inflation and deflation device is deflated according to the first initial air pressure to obtain the current deflation efficiency of the inflation and deflation device.

[0069] In some possible implementation manners, the control device of the embodiment of the present application can obtain the current deflation efficiency of the inflation and deflation device by deflating the inflation and deflation device to change the internal air pressure of the inflation and deflation device from the first initial air pressure to the preset first deflation air pressure. Specifically, the control device of the embodiment of the present application can deflate the inflation and deflation device when the internal air pressure of the inflation and deflation device is equal to the first initial air pressure, and suspend the deflation when the internal air pressure of the inflation and deflation device is changed from the first initial air pressure to the preset first deflation air pressure through the air pressure sensor. Meanwhile, the control device obtains the first deflation duration occupied by the change of the internal air pressure of the inflation and deflation device from the first initial air pressure to the first deflation air pressure. The first deflation air pressure can be understood as the internal air pressure of the inflation and deflation device after the deflation, and the first deflation duration can be understood as the deflation duration of the inflation and deflation device from the first initial air pressure to the first inflation air pressure. It can be understood that the control device of the embodiment of the present application can determine the current inflation efficiency of the inflation and deflation device according to the first initial air pressure, the first deflation air pressure and the first deflation duration.

[0070] For ease of understanding, the embodiments of the present application are illustrated in the following. Please refer to Figure 6 The control device of the embodiments of the present application can obtain the internal air pressure of the inflation and deflation device as the first initial air pressure Pn1 through the air pressure sensor when the inflation and deflation device corresponds to Figure 6 Further, when the internal air pressure of the inflation and deflation device is the first initial air pressure Pn1, the control device deflates the inflation and deflation device, and suspends deflation when the internal air pressure of the inflation and deflation device detected by the air pressure sensor is equal to the preset first deflation air pressure Pn3. The control device determines that the deflation time length corresponding to the increase of the internal air pressure of the inflation and deflation device from the first initial air pressure Pn1 to the first deflation air pressure Pn3 is the first deflation time length t2, and thus the current deflation efficiency of the inflation and deflation device at the point Ay can be obtained.

[0071] In some possible embodiments, the control device of the embodiments of the present application can obtain the current deflation efficiency of the inflation and deflation device by deflating the inflation and deflation device for a preset second deflation time length. Specifically, when the internal air pressure of the inflation and deflation device is equal to the first initial air pressure, the control device deflates the inflation and deflation device, and suspends deflation when the deflation time length is equal to the preset second deflation time length. Meanwhile, the control device detects the internal air pressure of the inflation and deflation device at this time as the second deflation air pressure through the air pressure sensor. The second deflation time length can be understood as the preset deflation time length of the inflation and deflation device, and the second deflation air pressure can be understood as the internal air pressure of the inflation and deflation device after deflation for the second deflation time length. It can be understood that the control device of the embodiments of the present application can determine the current deflation efficiency of the inflation and deflation device according to the first initial air pressure, the second deflation air pressure and the second deflation time length.

[0072] For ease of understanding, the embodiments of the present application are illustrated in the following. The control device of the embodiments of the present application can obtain the internal air pressure of the inflation and deflation device as the first initial air pressure Pn1 through the air pressure sensor. Further, when the internal air pressure of the inflation and deflation device is the first initial air pressure Pn1, the control device deflates the inflation and deflation device, and suspends deflation when the deflation time length is equal to the preset second deflation time length tc2. Meanwhile, the control device detects the internal air pressure of the inflation and deflation device at this time as the second deflation air pressure Pc2 through the air pressure sensor, and thus the current deflation efficiency of the inflation and deflation device can be obtained.

[0073] In step S102, when the current inflation and deflation efficiency does not belong to the expected inflation and deflation efficiency range, the inflation and deflation device is inflated and deflated to adjust the current inflation and deflation efficiency, so that the adjusted current inflation and deflation efficiency belongs to the expected inflation and deflation efficiency range.

[0074] In some possible implementation manners, after obtaining the current inflation and deflation efficiency of the inflation and deflation device, the control device of the embodiment of the present application can determine whether the volume of the inflation and deflation device is too large or too small through the current inflation and deflation efficiency of the inflation and deflation device, and then determine whether to adjust the current inflation and deflation efficiency of the inflation and deflation device.

[0075] It should be explained that in actual application, the volume (or deformation amount) of the inflation and deflation device frequently fluctuates, causing the current inflation and deflation efficiency of the inflation and deflation device to fluctuate. In order to avoid frequent adjustment of the inflation and deflation device due to slight fluctuation of the current inflation and deflation efficiency, the control device of the embodiment of the present application can determine that the volume of the inflation and deflation device is too large or too small when the current inflation and deflation efficiency of the inflation and deflation device does not belong to the expected inflation and deflation efficiency range of the inflation and deflation device, and the inflation and deflation of the inflation and deflation device needs to be performed to adjust the current inflation and deflation efficiency, so that the adjusted current inflation and deflation efficiency belongs to the expected inflation and deflation efficiency range. The expected inflation and deflation efficiency range refers to the inflation and deflation efficiency range corresponding to the inflation and deflation device when the volume of the inflation and deflation device is controlled within a reasonable range. It can be understood that when the current inflation and deflation efficiency of the inflation and deflation device belongs to the expected inflation and deflation efficiency range of the inflation and deflation device, it can be determined that the volume of the inflation and deflation device is within a reasonable range, and the air tightness and gas supply efficiency of the inflation and deflation device will not be adversely affected, and thus adjustment can not be performed.

[0076] That is, the control device of the present application can not adjust the inflation and deflation device when the current inflation and deflation efficiency of the inflation and deflation device belongs to the expected inflation and deflation efficiency range, so that the current inflation and deflation efficiency of the inflation and deflation device has a tolerance range, thereby reducing the number of adjustments when the deformation amount of the inflation and deflation device changes slightly, and having high applicability.

[0077] In some possible implementation manners, when the inflation and deflation device is a volume-variable inflation and deflation device, the control device in the embodiment of the present application can obtain the expected inflation and deflation efficiency range of the inflation and deflation device when the inflation and deflation device works in a stable state in advance, so as to determine whether the volume of the inflation and deflation device is too large or too small by detecting whether the current inflation and deflation efficiency of the inflation and deflation device belongs to the expected inflation and deflation efficiency range when the volume of the inflation and deflation device changes.

[0078] In some possible implementation manners, the control device can first acquire the expected inflation and deflation efficiency range of the inflation and deflation device when the inflation and deflation device works in the stable state, and then detect and adjust the current inflation and deflation efficiency of the inflation and deflation device according to the expected inflation and deflation efficiency range, so as to ensure that the current inflation and deflation efficiency of the inflation and deflation device is within the expected inflation and deflation efficiency range in different working environments (for example, a working environment in which the external air pressure changes due to the change of altitude, or a working environment in which the shell deforms due to external force, or a working environment in which the inflation and deflation device supplies air to the air-consuming device). The inflation and deflation device working in the stable state means that the volume of the inflation and deflation device is equal to the preset stable volume. When the volume of the inflation and deflation device is equal to the preset stable volume, the volume of the inflation and deflation device is neither too large nor too small, and the air tightness and air supply efficiency of the inflation and deflation device can reach the best state. It can be understood that the expected inflation and deflation efficiency range can be understood as the tolerance range of the current inflation and deflation efficiency of the inflation and deflation device when the volume of the inflation and deflation device is controlled within a reasonable range. When the current inflation and deflation efficiency of the inflation and deflation device is within the expected inflation and deflation efficiency range, it indicates that the volume of the inflation and deflation device is neither too large nor too small, and the inflation and deflation device has good air tightness and air supply efficiency.

[0079] In general, the control device of the embodiment of the present application can determine that the inflation and deflation device works in the stable state when the volume of the inflation and deflation device is equal to the preset stable volume, and then acquire the current inflation and deflation efficiency of the inflation and deflation device at this time, so as to acquire the expected inflation and deflation efficiency range of the inflation and deflation device according to the current inflation and deflation efficiency.

[0080] In some possible implementation manners, as can be known from the above, the deformation amount of the shell of the inflation and deflation device (that is, the volume of the inflation and deflation device) is related to the size of the external air pressure and the internal air pressure. For example, in some application scenarios, when the inflation and deflation device is in a high-altitude area, the external air pressure is low. At this time, in order to make the volume of the inflation and deflation device equal to the preset stable volume, the air pressure in the inflation and deflation device also needs to be reduced under the influence of the external air pressure. It can be understood that the reduction of the internal air pressure means that the amount of gas stored in the inflation and deflation device is reduced, which in turn causes the amount of gas stored in the inflation and deflation device to be less than the stable storage amount of the device, affecting the air supply efficiency.

[0081] It can be understood that, in order to avoid the influence of the change of the external air pressure on the determination of whether the inflation and deflation device works in the stable state, and in order to ensure that the internal stored gas can reach the stable storage amount of the device when the volume of the inflation and deflation device is the preset stable volume, the control device of the embodiment of the present application can determine that the volume of the inflation and deflation device is the preset stable volume when the external environment air pressure of the inflation and deflation device is the standard atmospheric pressure and the amount of internal stored gas is the preset stable storage amount, and then determine that the inflation and deflation device works in the stable state.

[0082] In some possible implementation manners, after determining that the inflation and deflation device works in the stable state, the inflation and deflation device can obtain the expected inflation efficiency and the expected deflation efficiency of the inflation and deflation device at this time, so as to determine the inflation and deflation efficiency of the inflation and deflation device according to the expected inflation efficiency and the expected deflation efficiency of the inflation and deflation device when the inflation and deflation device works in the stable state, and further determine the above-mentioned expected inflation and deflation efficiency range. Specifically, the inflation and deflation device can obtain the expected inflation efficiency and the expected deflation efficiency of the inflation and deflation device when the inflation and deflation device works in the stable state according to the following content.

[0083] Specifically, please refer to Figure 6 It can be understood that when the external air pressure is equal to the standard atmospheric pressure, it is assumed that the volume of the inflation and deflation device is equal to the preset stable volume, at this time, the inflation and deflation device corresponds to the Ax point shown in Figure 6 That is, the Ax point shown in Figure 6 corresponds to the inflation and deflation device working in the stable state.

[0084] In some possible implementation manners, the inflation and deflation device can obtain the air pressure in the inflation and deflation device as the second initial air pressure Pb1 when the inflation and deflation device works in the stable state. And on the basis of the air pressure in the inflation and deflation device being the second initial air pressure Pb1, the inflation and deflation device is inflated for a unit time td1, and the expected inflation efficiency of the inflation and deflation device is determined according to the air pressure in the inflation and deflation device after inflation and the second initial air pressure Pb1. It can be understood that the expected inflation efficiency is the air pressure change amount of the inflation and deflation device in a unit time when the inflation and deflation device works in the stable state.

[0085] For example, as shown in Figure 6 , when the air pressure in the inflation and deflation device is the second initial air pressure Pb1, it is assumed that after the inflation and deflation device is inflated for a unit time td1, the air pressure in the inflation and deflation device increases from Pb1 to Pb2, then the expected inflation efficiency of the inflation and deflation device can be determined as

[0086] In some possible implementation manners, on the basis of the air pressure in the inflation and deflation device being the second initial air pressure Pb1, the inflation and deflation device is inflated, so that the air pressure in the inflation and deflation device increases from the second initial air pressure Pb1 to Pa1, and the expected inflation efficiency of the inflation and deflation device is determined according to the inflation time of the inflation and deflation device.

[0087] For example, when the air pressure in the inflation and deflation device is the second initial air pressure Pb1, it is assumed that the inflation time of the inflation and deflation device is ta1 when the air pressure in the inflation and deflation device is increased from the second initial air pressure Pb1 to Pa1 through inflation, then the expected inflation efficiency of the inflation and deflation device can be determined as

[0088] In some possible implementation manners, the embodiment of the present application can determine the expected deflation efficiency of the inflation / deflation device on the basis of the internal air pressure of the inflation / deflation device being the second initial air pressure Pb1, deflating the inflation / deflation device in a unit time td2, and the internal air pressure of the inflation / deflation device after deflation and the second initial air pressure Pb1. The expected deflation efficiency can be understood as the air pressure change amount of the inflation / deflation device in a unit time when the inflation / deflation device works in a stable state.

[0089] For example, as shown in FIG. 3, when the internal air pressure of the inflation / deflation device is the second initial air pressure Pb1, it is assumed that the internal air pressure of the inflation / deflation device is reduced from Pb1 to Pb3 after deflation of the inflation / deflation device in a unit time td2, and the expected deflation efficiency of the inflation / deflation device can be determined as Figure 6

[0090] In some possible implementation manners, the embodiment of the present application can determine the expected deflation efficiency of the inflation / deflation device on the basis of the internal air pressure of the inflation / deflation device being the second initial air pressure Pb1, deflating the inflation / deflation device, reducing the internal air pressure of the inflation / deflation device from the second initial air pressure Pb1 to Pa2, and the deflation time of the inflation / deflation device.

[0091] For example, when the internal air pressure of the inflation / deflation device is the second initial air pressure Pb1, it is assumed that the internal air pressure of the inflation / deflation device is reduced from the second initial air pressure Pb1 to Pa2 by deflation, and the deflation time of the inflation / deflation device is ta2, and the expected deflation efficiency of the inflation / deflation device can be determined as

[0092] In general, the embodiment of the present application can determine the expected inflation efficiency or the expected deflation efficiency of the inflation / deflation device on the basis of the internal air pressure of the inflation / deflation device being the second initial air pressure Pb1, inflating and deflating the inflation / deflation device when the inflation / deflation device works in a stable state, and the internal air pressure of the inflation / deflation device after inflation / deflation, the second initial air pressure Pb1, and the inflation time or the deflation time.

[0093] ​In some possible embodiments, when the inflation and deflation device is inflated and deflated, the inflation and deflation device has a smaller change in air pressure when inflated to the same volume than when deflated to the same volume. That is, when the volume of the inflation and deflation device is equal to the stable volume, the expected inflation efficiency obtained by inflating the inflation and deflation device is smaller than the expected deflation efficiency obtained by deflating the inflation and deflation device. Further, the expected inflation efficiency can be taken as the minimum value of the expected inflation and deflation efficiency range, and the expected deflation efficiency can be taken as the maximum value of the expected inflation and deflation efficiency range, to generate the expected inflation and deflation efficiency range of the inflation and deflation device.

[0094] For example, according to the above content, the expected inflation efficiency a1 and the expected deflation efficiency a2 of the inflation and deflation device are obtained. Since the expected inflation efficiency a1 is smaller than the expected deflation efficiency a2, the expected inflation and deflation efficiency range of the inflation and deflation device can be a1 to a2.

[0095] It can be understood that when the current inflation and deflation efficiency of the inflation and deflation device belongs to the expected inflation and deflation efficiency range a1 to a2, the volume of the inflation and deflation device is within the tolerance range of the preset stable volume, that is, the volume of the inflation and deflation device is not too large or too small, and the air tightness and gas supply efficiency of the inflation and deflation device can be ensured. Therefore, the current inflation and deflation efficiency of the inflation and deflation device can be detected to determine whether the volume of the inflation and deflation device is too large or too small, and the inflation and deflation device can be adjusted when the volume of the inflation and deflation device is too large or too small, so that the inflation and deflation efficiency of the adjusted inflation and deflation device belongs to the expected inflation and deflation efficiency range, thereby ensuring that the volume of the inflation and deflation device is controlled within a reasonable range.

[0096] In some possible embodiments, the current inflation and deflation efficiency of the inflation and deflation device includes a current inflation efficiency and a current deflation efficiency. After the control device obtains the current inflation efficiency and the current deflation efficiency of the inflation and deflation device, the current inflation efficiency and the current deflation efficiency of the inflation and deflation device can be further determined to belong to the expected inflation and deflation efficiency range, to determine whether the volume of the inflation and deflation device is too large or too small. When the current inflation efficiency and the current deflation efficiency of the inflation and deflation device do not belong to the expected inflation and deflation efficiency range, the inflation and deflation device can be adjusted, so that the current inflation and deflation efficiency of the adjusted inflation and deflation device belongs to the expected inflation and deflation efficiency range, thereby controlling the volume of the inflation and deflation device within a reasonable range.

[0097] In some possible implementation manners, the control device of the embodiment of the present application can compare the current inflation efficiency and the current deflation efficiency of the inflation and deflation device with the maximum value and the minimum value of the expected inflation and deflation efficiency range to determine whether the current inflation efficiency and the current deflation efficiency of the inflation and deflation device belong to the expected inflation and deflation efficiency range.

[0098] It can be understood that, according to the above, the control device of the embodiment of the present application can obtain the expected inflation and deflation efficiency range according to the expected deflation efficiency and the expected inflation efficiency of the inflation and deflation device, and the expected deflation efficiency of the inflation and deflation device is greater than the expected inflation efficiency. Therefore, the maximum value of the expected inflation and deflation efficiency range is the expected deflation efficiency of the inflation and deflation device, and the minimum value of the expected inflation and deflation efficiency range is the expected inflation efficiency of the inflation and deflation device. That is, the control device of the embodiment of the present application can compare the current inflation efficiency and the current deflation efficiency of the inflation and deflation device with the expected deflation efficiency and the expected inflation efficiency to determine whether the current inflation efficiency and the current deflation efficiency of the inflation and deflation device belong to the expected inflation and deflation efficiency range.

[0099] In some possible implementation manners, when the current inflation efficiency and the current deflation efficiency of the inflation and deflation device are both greater than the expected deflation efficiency, since the expected deflation efficiency is the maximum value of the expected inflation and deflation efficiency range, it can be determined that the current inflation efficiency and the current deflation efficiency of the inflation and deflation device do not belong to the expected inflation and deflation efficiency range, and the control device needs to adjust the inflation and deflation device. It should be explained that, according to the above, when the volume of the inflation and deflation device is different, the current inflation and deflation efficiency of the corresponding inflation and deflation device is different, and the smaller the volume of the inflation and deflation device is, the greater the current inflation and deflation efficiency of the corresponding inflation and deflation device is. That is, the smaller the volume of the inflation and deflation device is, the greater the current inflation efficiency or the current deflation efficiency of the inflation and deflation device is.

[0100] Therefore, when the current inflation efficiency and the current deflation efficiency of the inflation and deflation device are both greater than the expected deflation efficiency, it indicates that the volume of the inflation and deflation device is smaller than the preset stable volume. It can be understood that, in the case that the volume of the inflation and deflation device is smaller than the preset stable volume, the deformation amount of the inflation and deflation device is too small, which will adversely affect the gas supply efficiency of the inflation and deflation device. Therefore, the control device of the embodiment of the present application can inflate the inflation and deflation device to increase the volume of the inflation and deflation device, so as to reduce the current inflation and deflation efficiency of the inflation and deflation device, so that the reduced current inflation and deflation efficiency belongs to the expected inflation and deflation efficiency range, so that the volume of the inflation and deflation device is controlled within a reasonable range.

[0101] In some possible implementation manners, when the current inflation efficiency and the current deflation efficiency of the inflation and deflation device are both less than the expected inflation efficiency, since the expected inflation efficiency is the minimum value of the above-mentioned expected inflation and deflation efficiency range, it can be determined that the current inflation efficiency and the current deflation efficiency of the inflation and deflation device do not belong to the expected inflation and deflation efficiency range, and the inflation and deflation device needs to be adjusted. It can be known from the above that the current inflation and deflation efficiency of the corresponding inflation and deflation device is different when the volume of the inflation and deflation device is different, and the current inflation and deflation efficiency of the corresponding inflation and deflation device is smaller when the volume of the inflation and deflation device is larger. That is, the volume of the inflation and deflation device is larger when the current inflation efficiency or the current deflation efficiency of the inflation and deflation device is smaller.

[0102] Therefore, when the current inflation efficiency and the current deflation efficiency of the inflation and deflation device are both less than the expected inflation efficiency, it indicates that the volume of the inflation and deflation device is larger than the preset stable volume. It can be understood that, when the volume of the inflation and deflation device is larger than the preset stable volume, the volume of the inflation and deflation device is too large, which will have an adverse effect on the air tightness of the inflation and deflation device. Therefore, the control device of the embodiment of the present application can deflate the inflation and deflation device to reduce the volume of the inflation and deflation device, so as to increase the current inflation and deflation efficiency of the inflation and deflation device, so that the increased current inflation and deflation efficiency belongs to the expected inflation and deflation efficiency range, so that the volume of the inflation and deflation device is controlled within a reasonable range.

[0103] In some possible implementation manners, it can be known from the above that, in order to avoid frequent adjustment of the inflation and deflation device, the control device of the embodiment of the present application can determine that the current inflation efficiency of the inflation and deflation device belongs to the expected inflation and deflation efficiency range when the current inflation efficiency or the current deflation efficiency of the inflation and deflation device belongs to the above-mentioned expected inflation and deflation efficiency range. At this time, the volume of the inflation and deflation device is within a reasonable deformation range, and the deformation amount will not be too large or too small, which can ensure good air tightness and gas supply efficiency, and thus adjustment is not needed.

[0104] Specifically, when the current inflation efficiency of the inflation and deflation device is greater than the expected inflation efficiency and less than the expected deflation efficiency, it can be determined that the current inflation efficiency of the inflation and deflation device belongs to the expected inflation and deflation efficiency range, and the control device does not need to adjust the inflation and deflation device at this time.

[0105] Specifically, when the current deflation efficiency of the inflation and deflation device is greater than the expected inflation efficiency and less than the expected deflation efficiency, it can be determined that the current deflation efficiency of the inflation and deflation device belongs to the expected inflation and deflation efficiency range, and the control device does not need to adjust the inflation and deflation device at this time.

[0106] In some possible implementation manners, for ease of understanding, the embodiment of the present application is exemplarily described in the following content in combination with Figure 6 Specifically, please refer to Figure 6Assuming the external ambient pressure is standard atmospheric pressure, the corresponding pressure of the inflation / deflation equipment is... Figure 6 Given point Ax in the diagram, and the expected inflation efficiency of the inflation / deflation device being a1 and the expected deflation efficiency being a2, the expected inflation / deflation efficiency range of the device can be determined to be a1 to a2. When external forces cause deformation of the device's casing, the volume of the device changes, and the internal air pressure changes. At this time, the corresponding... Figure 7 Point Ay in the equation, and the current inflation efficiency of the inflation / deflation device is an1, and the current deflation efficiency is an2.

[0107] In order to maintain the current inflation / deflation efficiency of the inflation / deflation device within the expected inflation / deflation efficiency range, the control device of this application embodiment can deflate the inflation / deflation device so that the current inflation / deflation efficiency of the inflation / deflation device after deflation is within the expected inflation / deflation efficiency range of a1 to a2. It can be understood that when the current inflation / deflation efficiency of the inflation / deflation device is within the expected inflation / deflation efficiency range, the volume of the inflation / deflation device is maintained within a reasonable range.

[0108] In some feasible implementations, for ease of understanding, the embodiments of this application are combined with the following content. Figure 7 Examples will be provided. For details, please refer to [link / reference]. Figure 7 , Figure 7 This is another schematic flowchart illustrating the control method for the inflation / deflation device provided in an embodiment of this application. Figure 7 The control method shown includes at least the following steps S401-S408. In this embodiment, the control device obtains the desired inflation / deflation efficiency range of the inflation / deflation device in step S401, and obtains the first initial pressure of the inflation / deflation device in step S402. Further, in step S403, the device is inflated / deflated according to the first initial pressure to obtain the current inflation / deflation efficiency. Then, in step S404, the control device determines whether the current inflation / deflation efficiency falls within the desired range and decides whether to adjust it. If the current inflation / deflation efficiency falls within the desired range, it indicates that the volume of the device is within a reasonable range and will not adversely affect the airtightness and gas supply efficiency. The control device then completes the adjustment of the device in step S408. If the current inflation / deflation efficiency of the inflation / deflation equipment is not within the expected inflation / deflation efficiency range, it indicates that the volume of the inflation / deflation equipment is too large or too small, which will have an adverse effect on the airtightness and gas supply efficiency of the inflation / deflation equipment, and adjustment is required.

[0109] Specifically, such as Figure 7As shown, in the case that the current inflation and deflation efficiency of the inflation and deflation device does not belong to the expected inflation and deflation efficiency range, the control device of the embodiment of the application judges whether the current inflation and deflation efficiency is greater than the expected inflation and deflation efficiency range through step S404, and in the case that the current inflation and deflation efficiency is greater than the expected inflation and deflation efficiency range, the control device of the embodiment of the application inflates the inflation and deflation device through step S406 to reduce the current inflation and deflation efficiency of the inflation and deflation device; and in the case that the current inflation and deflation efficiency is less than the expected inflation and deflation efficiency range, the control device of the embodiment of the application deflates the inflation and deflation device through step S407 to increase the current inflation and deflation efficiency of the inflation and deflation device.

[0110] It should be noted that the specific implementation of steps S401-S408 for adjusting the current inflation and deflation efficiency of the inflation and deflation device can refer to the specific implementation of steps S101-S102, which will not be repeated here.

[0111] It can be understood that after the control device inflates and deflates the inflation and deflation device based on the size of the current inflation and deflation efficiency and the expected inflation and deflation efficiency range to adjust the current inflation and deflation efficiency of the inflation and deflation device, further, it can be judged whether the adjusted current inflation and deflation efficiency belongs to the expected inflation and deflation efficiency range, and in the case that the adjusted current inflation and deflation efficiency belongs to the expected inflation and deflation efficiency range, the adjustment of the inflation and deflation device is completed. Figures 1 to 7 As shown, the adjustment of the inflation and deflation device is continued according to the above steps until the adjusted current inflation and deflation efficiency belongs to the expected inflation and deflation efficiency range, so that the volume of the inflation and deflation device is controlled within a reasonable range, and the adjustment of the inflation and deflation device is completed.

[0112] In this application, when the inflation / deflation device is a volume-variable inflation / deflation device, the control device can pre-obtain the expected inflation / deflation efficiency range of the device when it is operating in a stable state. This expected inflation / deflation efficiency range refers to the range of inflation / deflation efficiency corresponding to the device when its volume is within a reasonable range. Furthermore, when the volume of the inflation / deflation device changes, the control device can obtain a first initial pressure inside the device and inflate / deflate it according to this first initial pressure to obtain the current inflation / deflation efficiency. When the current inflation / deflation efficiency does not fall within the expected inflation / deflation efficiency range, it indicates that the device's volume is too large or too small. In this case, the control device can inflate / deflate the device to adjust its current inflation / deflation efficiency so that the adjusted efficiency falls within the expected range, thus controlling the device's volume within a reasonable range. This avoids the device becoming too large or too small and ensures its normal operation. For example, it can avoid the problems of excessively large charging / discharging equipment, which leads to poor airtightness and a short service life. Simultaneously, it can avoid the problem of excessively small charging / discharging equipment, which results in low gas supply efficiency. Furthermore, by using the current charging / discharging efficiency of the equipment as a relationship point between internal and external air pressures (i.e., a reference point), reflecting the relationship between the internal air pressure and the external ambient air pressure, and reflecting the volume change of the equipment, this current charging / discharging efficiency can be controlled as a variable to maintain it within the desired range. This is equivalent to maintaining the charging / discharging volume within a reasonable range, improving the accuracy of equipment control. It also eliminates the need to measure external ambient air pressure, avoiding the low accuracy of control methods based solely on ambient air pressure.
