TECHNICAL FIELD

[0001] The present application relates to the technical field of electronics, and in particular to a control method and device of a gas charging and discharging equipment, a vehicle and a readable storage medium. BACKGROUND

[0002] The gas charging and discharging equipment of the vehicle can be inflated by a gas charging element and store the inflated gas, or be deflated by a gas discharging element to provide gas to other equipment of the vehicle.

[0003] It is found in practice that if the shell of the gas charging and discharging equipment bears too large pressure, the joint between the gas charging and discharging equipment and other equipment (such as the gas charging connection port of the motor) will be damaged, thereby causing poor air tightness of the gas charging and discharging equipment and reducing the service life of the gas charging and discharging equipment. At the same time, if the shell of the gas charging and discharging equipment bears too small pressure, the amount of gas stored in the gas charging and discharging equipment is reduced, which will affect the gas supply efficiency of the gas charging and discharging equipment. SUMMARY

[0008] In a possible implementation, the determining that the gas charging and discharging device is in a stable state when the amount of gas stored in the gas charging and discharging device is a preset stable storage amount when the external environment pressure is a standard atmospheric pressure includes: charging and discharging the gas charging and discharging device to adjust the gas pressure in the gas charging and discharging device when the external environment pressure of the gas charging and discharging device is a standard atmospheric pressure; and determining that the amount of gas stored in the gas charging and discharging device is a preset stable storage amount and that the gas charging and discharging device is in a stable state when the adjusted gas pressure in the gas charging and discharging device is equal to a preset standard borne pressure.

[0009] In a possible implementation, the determining the expected borne pressure of the gas charging and discharging device according to the expected borne pressure range, the current borne pressure, and the initial gas pressure includes: searching for a standard borne pressure of the gas charging and discharging device according to the expected borne pressure range; obtaining a ratio between the standard borne pressure and the current borne pressure; and determining a product between the ratio and the initial gas pressure as the expected borne pressure of the gas charging and discharging device.

[0010] In a possible implementation, the charging and discharging the gas charging and discharging device according to the expected borne pressure and the initial gas pressure to adjust the current borne pressure of the shell of the gas charging and discharging device so that the adjusted current borne pressure belongs to the expected borne pressure range includes: charging the gas charging and discharging device to reduce the current borne pressure of the gas charging and discharging device so that the reduced current borne pressure belongs to the expected borne pressure range when the initial gas pressure is less than the expected borne pressure; and discharging the gas charging and discharging device to increase the current borne pressure of the gas charging and discharging device so that the increased current borne pressure belongs to the expected borne pressure range when the initial gas pressure is greater than the expected borne pressure.

[0011] In a possible implementation, the charging the gas charging and discharging device when the initial gas pressure is less than the expected borne pressure includes: controlling a motor connected to a gas charging port of the gas charging and discharging device to operate to charge the gas charging and discharging device when the initial gas pressure is less than the expected borne pressure.

[0012] In a possible implementation, when the initial air pressure is greater than the expected bearing air pressure, the gas charging and discharging device is discharged, including: when the initial air pressure is greater than the expected bearing air pressure, controlling the electromagnetic valve connected with the gas discharging port of the gas charging and discharging device to operate to discharge the gas charging and discharging device.

[0013] In a second aspect, the present application also provides a control device of a gas charging and discharging device, the device comprising:

[0014] a pressure obtaining module, configured to obtain a current bearing pressure of a shell of the gas charging and discharging device;

[0015] an air pressure determining module, configured to, when the current bearing pressure of the gas charging and discharging device does not belong to the expected bearing pressure range, determine an expected bearing air pressure of the shell of the gas charging and discharging device according to the expected bearing pressure range, the current bearing pressure and an initial air pressure;

[0016] a gas charging and discharging module, configured to charge and discharge the gas charging and discharging device according to the expected bearing air pressure and the initial air pressure, to adjust the current bearing pressure of the shell of the gas charging and discharging device, so that the adjusted current bearing pressure belongs to the expected bearing pressure range.

When the current bearing pressure of the gas charging and discharging device is not within the expected bearing pressure range, it indicates that the current bearing pressure of the gas charging and discharging device is too large or too small. The expected bearing pressure range refers to the bearing pressure range of the gas charging and discharging device shell when the gas charging and discharging device has high gas supply efficiency and good air tightness. Further, the control device can obtain the initial air pressure inside the gas charging and discharging device, and dynamically determine the expected bearing air pressure of the gas charging and discharging device shell according to the initial air pressure, the expected bearing pressure range, and the current bearing pressure. Further, the gas charging and discharging device is charged and discharged according to the expected bearing air pressure and the initial air pressure of the gas charging and discharging device to adjust the current bearing pressure of the gas charging and discharging device shell, so that the adjusted current bearing pressure is within the expected bearing pressure range. This can avoid the bearing pressure of the gas charging and discharging device shell being too large or too small, thereby ensuring the good air tightness and gas supply efficiency of the gas charging and discharging device and prolonging the service life of the gas charging and discharging device. At the same time, the surface bearing pressure of the gas charging and discharging device shell (i.e. the current bearing pressure) is used as the relationship point (i.e. the contact point) between the internal and external air pressures, i.e. the surface bearing pressure reflects the relationship between the internal air pressure of the gas charging and discharging device and the external environmental air pressure, and the surface bearing pressure is used as a control variable to control the bearing pressure of the gas charging and discharging device shell to be maintained within the expected bearing pressure range, thereby improving the control accuracy of the gas charging and discharging device. It is not necessary to measure the external environmental air pressure, thereby avoiding the problem of low control accuracy of the control method based on a single environmental air pressure.

[0030] 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 labor fall within the scope of protection of the present application.

[0031] The following will be described in detail respectively.

[0032] The terms “first”, “second”, “third”, and “fourth” and the like in the specification and claims of the present application and the drawings 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 that includes a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or units inherent to the process, method, product or device.

[0033] Reference to “an embodiment” in this text means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor does it necessarily refer to a separate or alternative embodiment in isolation from other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] It should be understood that the inflation and deflation device refers to a device with inflation and deflation functions. For example, in some application scenarios, the inflation and deflation device can be a gas pump in a vehicle. The vehicle can inflate the gas pump through a motor, and the gas pump stores the inflated gas. The vehicle can also deflate the gas pump through a solenoid valve to provide the stored gas in the gas pump to the gas-consuming equipment of the vehicle for use, and at the same time, the excess gas in the gas pump can be discharged to avoid excessive gas pressure in the inflation and deflation device.

[0035] In some possible embodiments, the inflation and deflation device can include a variable-volume container or a fixed-volume inflation and deflation device. When the inflation and deflation device is a variable-volume container, the volume of the inflation and deflation device can change because the shell of the variable-volume container can deform. When the inflation and deflation device is a fixed-volume inflation and deflation device, the volume of the inflation and deflation device does not change because the shell of the fixed-volume inflation and deflation device cannot deform.

[0036] It should be noted that the control method provided in the present application can be applied to the use scenario of the inflation and deflation device being the fixed-volume inflation and deflation device described above. For ease of understanding, the inflation and deflation device described in the following content of the present application is a fixed-volume inflation and deflation device, which is referred to as an inflation and deflation device for short.

[0037] In some possible embodiments, as known from the above, the inflation and deflation device can be used to store gas. Generally, in order to ensure stable gas storage, the amount of gas stored in the inflation and deflation device should not exceed the rated maximum amount of the device. When too much gas is inflated, the gas pressure in the inflation and deflation device rises too much, which can cause the inflation and deflation device shell to bear too much pressure, thereby affecting the stability of the inflation and deflation device. At the same time, because the shell of the inflation and deflation device does not deform with the change of the internal gas pressure, when the inflation and deflation device shell bears too much pressure, the various junctions (for example, the junctions of the inflation pipeline and the device body) of the inflation and deflation device shell can be irreversibly damaged in a high-pressure environment, thereby adversely affecting the gas tightness of the inflation and deflation device. Further, the shell of the inflation and deflation device bears a large pressure for a long time, which can also reduce the service life of the inflation and deflation device.

[0038] 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, and meanwhile, the pressure bearing capacity of the shell of the gas charging and discharging device is greater, resulting in that 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, and meanwhile, the pressure bearing capacity of the shell of the gas charging and discharging device is smaller, resulting in that the gas supply efficiency of the gas charging and discharging device is lower.

[0039] Generally, when the pressure bearing capacity of the shell of the gas charging and discharging device is too great, the air tightness of the gas charging and discharging device is affected, resulting in that the service life of the gas charging and discharging device is reduced. When the pressure bearing capacity of the shell of the gas charging and discharging device is too small, it indicates that 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.

[0040] To solve the problem, the embodiment of the present application provides a control method of a gas charging and discharging device, which can ensure the good air tightness and gas supply efficiency of the gas charging and discharging device while the gas charging and discharging device is stably working, and prolong the service life of the gas charging and discharging device.

[0041] 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 pressure bearing capacity of the gas charging and discharging device, and is specifically described as follows. Please refer to Figure 1 , Figure 1 A system architecture schematic diagram is provided for the embodiment of the present application. As shown in Figure 1 , 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.

[0042] 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 1 . Specifically, Figure 1The control device shown can detect and control the current pressure of the inflation / deflation equipment in real time. For example, when the internal pressure of the inflation / deflation equipment changes, causing a change in the current pressure of the equipment shell, the control device can detect whether the current pressure of the inflation / deflation equipment is within the expected pressure range. If the current pressure is not within the expected pressure range, the control device can adjust the current pressure of the inflation / deflation equipment to ensure that the adjusted current pressure is within the expected pressure range, thus guaranteeing that the current pressure of the inflation / deflation equipment is within a reasonable pressure bearing range.

[0043] For further details, please refer to Figure 2 , Figure 2 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 1 The control device shown is used to perform the operation, such as Figure 2 As shown, the control method may include at least the following steps S101-S103.

[0044] Step S101: Obtain the current pressure that the housing of the inflation / deflation device can withstand.

[0045] In some feasible implementations, the current pressure borne by the charging / discharging device housing refers to the resultant force exerted on the housing by the pressure difference between the external ambient air pressure and the internal air pressure of the charging / discharging device. When the external ambient air pressure or the internal air pressure changes, the pressure difference between the inside and outside of the charging / discharging device (i.e., the pressure difference between the external ambient air pressure and the internal air pressure) changes, thereby affecting the current pressure borne by the charging / discharging device housing. Therefore, in this application embodiment, the current pressure borne by the charging / discharging device housing can be used as the link between the two variables of external ambient air pressure and internal air pressure. When both the external ambient air pressure and the internal air pressure of the charging / discharging device change, resulting in a change in the pressure difference between the inside and outside of the charging / discharging device housing, the current pressure borne by the charging / discharging device housing can be detected and controlled to adjust the pressure difference between the inside and outside of the charging / discharging device, i.e., the current pressure borne by the housing.

[0046] For example, when the vehicle enters a high-altitude area, the external environment air pressure of the gas charging and discharging device (e.g., the air pump described above) of the vehicle decreases due to the low atmospheric pressure in the high-altitude area. Meanwhile, if the gas charging and discharging device supplies gas to the gas using device, the decrease of the internal gas also causes the internal air pressure of the gas charging and discharging device to decrease, that is, the external environment air pressure and the internal air pressure of the gas charging and discharging device both change. Since the pressure difference between the external environment air pressure and the internal air pressure of the gas charging and discharging device affects the current bearing pressure of the shell of the gas charging and discharging device, the control device of the embodiment of the present application can adjust the current bearing pressure of the gas charging and discharging device when the external environment air pressure and the internal air pressure of the gas charging and discharging device both change by detecting the current bearing pressure of the shell of the gas charging and discharging device, so as to ensure that the current bearing pressure of the gas charging and discharging device is not too large or too small.

[0047] In general, the control device in the embodiment of the present application can detect and control the current bearing pressure of the shell of the gas charging and discharging device by taking the current bearing pressure of the shell of the gas charging and discharging device as the contact point of the external environment air pressure and the internal air pressure of the gas charging and discharging device without identifying the external environment air pressure, and further adjust the current bearing pressure of the shell of the gas charging and discharging device when the current bearing pressure of the shell of the gas charging and discharging device is too large or too small.

[0048] In some possible implementations, the control device of the embodiment of the present application can be connected with the air pressure sensor and the pressure sensor in the shell of the gas charging and discharging device respectively, so as to detect the air pressure in the shell of the gas charging and discharging device in real time through the air pressure sensor and detect the bearing pressure of the shell of the gas charging and discharging device in real time through the pressure sensor. It can be understood that the control device of the embodiment of the present application can detect the bearing pressure of the shell of the gas charging and discharging device in real time through the pressure sensor. In some application scenarios, the control device of the embodiment of the present application can determine the bearing pressure of the shell of the gas charging and discharging device detected at the current time as the current bearing pressure.

[0049] In step S102, when the current bearing pressure of the shell of the gas charging and discharging device does not belong to the expected bearing pressure range, the expected bearing air pressure of the shell of the gas charging and discharging device is determined according to the expected bearing pressure range, the current bearing pressure and the initial air pressure.

[0050] In some possible implementation manners, in order to ensure that the current bearing pressure of the gas charging and discharging device shell is not too large or too small, the control device can obtain an expected bearing pressure range of the gas charging and discharging device shell in advance, and detect and control the bearing pressure of the gas charging and discharging device shell in real time according to the expected bearing pressure range, so as to ensure that the bearing pressure of the shell is maintained in the expected bearing pressure range in different working environments (for example, a working environment in which the external environment air pressure changes due to altitude change, or a working environment in which the internal air pressure changes due to external force factors). The expected bearing pressure range refers to a bearing pressure range of the gas charging and discharging device shell when the gas charging and discharging device has a relatively high gas supply efficiency and a relatively good air tightness.

[0051] In some possible implementation manners, when the gas charging and discharging device is a volume-fixed gas charging and discharging device, the control device can obtain an expected bearing pressure range of the gas charging and discharging device shell when the gas charging and discharging device works in a stable state in advance. Specifically, because the pressure bearing performance of the gas charging and discharging device shell does not change with the change of the working environment, the expected bearing pressure range of the gas charging and discharging device is the same in different working environments. Therefore, the control device can obtain the expected bearing pressure range when the gas charging and discharging device works in a stable state in advance, so as to detect and control the current bearing pressure of the gas charging and discharging device shell in different working environments according to the expected bearing pressure range. Specifically, the embodiments of the present application explain the specific implementation manners of obtaining the expected bearing pressure range when the gas charging and discharging device works in a stable state in the following content.

[0052] In some possible implementation manners, in the case that the gas charging and discharging device is a volume-fixed gas charging and discharging device, the gas charging and discharging device working in a stable state means that the current bearing pressure of the gas charging and discharging device shell is equal to a preset standard bearing pressure. That is to say, the control device in the embodiments of the present application can determine that the gas charging and discharging device works in a stable state when the bearing pressure of the gas charging and discharging device shell is equal to the standard bearing pressure. Further, the control device can obtain the current bearing pressure of the gas charging and discharging device shell at this time, and obtain the expected bearing pressure range of the gas charging and discharging device shell according to the current bearing pressure.

[0053] In some possible implementation manners, the embodiments of the present application can obtain the expected bearing pressure range of the gas charging and discharging device shell when the gas charging and discharging device works in a stable state according to the steps shown in Figure 3 For ease of understanding, the embodiments of the present application are described by taking the control device as an example, that is, each step of the control method provided by the embodiments of the present application can be executed by the control device shown in Figure 3 For ease of understanding, the embodiments of the present application are described by taking the control device as an example, that is, each step of the control method provided by the embodiments of the present application can be executed by the control device shown in Figure 1 For ease of understanding, the embodiments of the present application are described by taking the control device as an example, that is, each step of the control method provided by the embodiments of the present application can be executed by the control device shown in Figure 3 , Figure 3 For ease of understanding, the embodiments of the present application are described by taking the control device as an example, that is, each step of the control method provided by the embodiments of the present application can be executed by the control device shown inFigure 3 As shown, the control method can at least include the following steps S201-S205.

[0054] Step S201, when the external environment air pressure of the gas charging and discharging device is standard atmospheric pressure, the gas charging and discharging device is charged and discharged to adjust the air pressure inside the gas charging and discharging device.

[0055] In some possible implementation manners, it can be known from the above that, in the embodiments of the present application, the control device can determine that the gas charging and discharging device works in a stable state by detecting that the current bearing pressure of the shell of the gas charging and discharging device is equal to the standard bearing pressure, and then obtain the expected bearing pressure range when the gas charging and discharging device works in the stable state. Therefore, the control device can obtain the standard bearing pressure of the gas charging and discharging device before obtaining the expected bearing pressure range, so as to determine whether the gas charging and discharging device works in the stable state according to the standard bearing pressure. The standard bearing pressure of the gas charging and discharging device can be understood as the current bearing pressure of the shell of the gas charging and discharging device corresponding to the best airtightness and the highest gas supply efficiency of the gas charging and discharging device.

[0056] It can be understood that, as known from the above, the current bearing pressure of the shell of the gas charging and discharging device is related to the size of the external environment air pressure and the internal air pressure. That is to say, in different working environments, when the current bearing pressure of the shell of the gas charging and discharging device is the standard bearing pressure, the size of the internal air pressure of the gas charging and discharging device is related to the working environment. For example, in some application scenarios, when the gas charging and discharging device is in a high-altitude area, the external environment air pressure is low. At this time, in order to reduce the pressure difference between the inside and outside of the gas charging and discharging device, make the current bearing pressure of the shell of the gas charging and discharging device equal to the standard bearing pressure, the internal air pressure of the gas charging and discharging device will also decrease under the influence of the external environment air pressure. It can be understood that, in the case that the volume of the gas charging and discharging device is fixed, the decrease of the internal air pressure means that the amount of gas stored in the gas charging and discharging device decreases, thereby causing that, when the current bearing pressure of the shell of the gas charging and discharging device is equal to the standard bearing pressure, the amount of gas stored in the gas charging and discharging device does not reach the stable storage amount of the device, affecting the gas supply efficiency.

[0057] In some possible implementation manners, in order to avoid the influence of the change of the external environment air pressure on the standard bearing pressure of the gas charging and discharging device, and to ensure that the internal storage gas can reach the stable storage amount of the device when the bearing pressure of the gas charging and discharging device shell is the standard bearing pressure, the control device in the embodiment of the present application can determine the current bearing pressure of the gas charging and discharging device shell as the standard bearing pressure when it is detected that the external environment air pressure of the gas charging and discharging device is the standard atmospheric pressure and the internal air pressure is equal to the standard bearing air pressure. The standard bearing air pressure can be understood as the air pressure in the gas charging and discharging device when the external environment air pressure is the standard atmospheric pressure and the gas charging and discharging device stores the stable storage amount of the device.

[0058] That is, the control device in the embodiment of the present application can determine the resultant force of the pressure difference between the standard atmospheric pressure and the standard bearing air pressure acting on the gas charging and discharging device shell as the standard bearing pressure of the gas charging and discharging device when the external environment air pressure of the gas charging and discharging device is the standard atmospheric pressure and the internal air pressure is the standard bearing air pressure. The control device can ensure the gas supply efficiency of the gas charging and discharging device by making the internal air pressure of the gas charging and discharging device the standard bearing air pressure while accurately obtaining the standard bearing pressure.

[0059] In some possible implementation manners, the control device in the embodiment of the present application can be connected with the air pressure sensor and the pressure sensor in the gas charging and discharging device respectively, to detect the air pressure in the gas charging and discharging device in real time through the air pressure sensor and detect the current bearing pressure of the gas charging and discharging device shell in real time through the pressure sensor.

[0060] Specifically, the control device in the embodiment of the present application can adjust the air pressure in the gas charging and discharging device by charging and discharging the gas charging and discharging device when the external environment air pressure of the gas charging and discharging device is the standard atmospheric pressure.

[0061] Step S202: When the adjusted air pressure in the gas charging and discharging device is equal to the preset standard bearing air pressure, the amount of the gas stored in the gas charging and discharging device is the preset stable storage amount, and it is determined that the gas charging and discharging device works in a stable state.

[0062] In some possible implementation, as can be seen from the above, the standard bearing pressure of the gas charging and discharging device shell is the same in different working environments. Therefore, in various different working environments, the control device can determine that the gas charging and discharging device is in a stable state by detecting that the current bearing pressure of the gas charging and discharging device shell detected by the pressure sensor is equal to the standard bearing pressure in real time. It can be understood that, in the process of charging and discharging the gas charging and discharging device, the internal gas pressure of the gas charging and discharging device is detected in real time by the gas pressure sensor, and the charging and discharging of the gas charging and discharging device is stopped when the internal gas pressure is equal to the preset standard bearing gas pressure. It can be understood that, at this time, the amount of gas stored in the gas charging and discharging device is equal to the stable storage amount of the device, and thus it can be determined that the gas charging and discharging device is in a stable state.

[0063] In step S203, the bearing pressure of the shell when the gas charging and discharging device is in a stable state is determined as the standard bearing pressure.

[0064] In some possible implementation, as can be seen from the above, when the internal gas pressure of the gas charging and discharging device is the standard bearing gas pressure and the external environmental gas pressure is the standard atmospheric pressure, the amount of gas stored in the gas charging and discharging device is the preset stable storage amount, and the gas charging and discharging device is in a stable state. The control device of the embodiment of the present application can determine the current bearing pressure of the gas charging and discharging device shell under the action of the internal and external gas pressures at this time as the standard bearing pressure of the gas charging and discharging device.

[0065] Specifically, the control device of the embodiment of the present application can stop charging and discharging the gas charging and discharging device when the internal gas pressure of the gas charging and discharging device detected by the gas pressure sensor in real time is equal to the standard bearing gas pressure. Then, the control device obtains the current bearing pressure of the shell of the gas charging and discharging device when the internal gas pressure is equal to the standard bearing gas pressure by the pressure sensor, and determines the current bearing pressure as the standard bearing pressure of the gas charging and discharging device.

[0066] It should be understood that, as can be seen from the above, the pressure-bearing performance of the gas charging and discharging device shell does not change with the change of the working environment, and therefore, when the working environment of the gas charging and discharging device changes or is affected by external force, the standard bearing pressure of the gas charging and discharging device does not change. That is to say, even if the gas charging and discharging device works in a high-altitude area or the shell is deformed under the action of external force, the stable storage amount of the gas charging and discharging device will change, but since the maximum pressure that can be borne by each joint of the gas charging and discharging device shell does not change, the standard bearing pressure of the gas charging and discharging device remains the same in different working environments. Similarly, the expected bearing pressure range of the gas charging and discharging device can be obtained according to the standard bearing pressure, and therefore, the expected bearing pressure range of the gas charging and discharging device remains the same in different working environments.

[0067] In general, the control device of the embodiment of the present application can detect and control the current bearing pressure of the shell of the inflation and deflation device under different working environments based on the standard bearing pressure and the expected bearing pressure range of the inflation and deflation device when the inflation and deflation device works in a stable state.

[0068] In step S204, the maximum expected bearing pressure and the minimum expected bearing pressure of the inflation and deflation device are obtained according to the standard bearing pressure.

[0069] In some possible implementations, after the control device of the embodiment of the present application obtains the standard bearing pressure of the inflation and deflation device according to the above content, the control device can further obtain the maximum expected bearing pressure and the minimum expected bearing pressure of the inflation and deflation device according to the standard bearing pressure.

[0070] It should be explained that, after the control device of the embodiment of the present application obtains the standard bearing pressure of the inflation and deflation device, if the inflation and deflation device is directly detected and controlled according to the standard bearing pressure, as long as the current bearing pressure of the shell of the inflation and deflation device is not equal to the standard bearing pressure, the bearing pressure of the shell of the inflation and deflation device needs to be adjusted until the current bearing pressure of the shell of the inflation and deflation device is equal to the standard bearing pressure. However, in actual applications, the current bearing pressure of the shell of the inflation and deflation device frequently fluctuates. Therefore, in order to avoid frequent adjustment of the inflation and deflation device due to the slight fluctuation of the current bearing pressure of the shell, the control device of the embodiment of the present application can further obtain the maximum expected bearing pressure and the minimum expected bearing pressure of the inflation and deflation device according to the standard bearing pressure after obtaining the standard bearing pressure of the inflation and deflation device according to the above content. When the current bearing pressure of the shell of the inflation and deflation device is less than the maximum expected bearing pressure and greater than the minimum expected bearing pressure, the inflation and deflation device can maintain a relatively high gas supply efficiency and a relatively good air tightness.

[0071] Therefore, when the current bearing pressure of the shell of the inflation and deflation device fluctuates, as long as the current bearing pressure of the shell after the fluctuation is less than the maximum expected bearing pressure of the inflation and deflation device and less than the minimum expected bearing pressure, it can be determined that the shell of the inflation and deflation device is still in a reasonable bearing pressure range, and the air tightness and the gas supply efficiency of the inflation and deflation device will not be adversely affected, and no adjustment needs to be performed.

[0072] For ease of understanding, the embodiments of the present application are exemplified in the following. Specifically, it is assumed that the standard bearing pressure of the inflation and deflation equipment is A, and the maximum deviation value of the standard bearing pressure is a. The maximum deviation value of the standard bearing pressure refers to the maximum value of the deviation value of the current bearing pressure of the inflation and deflation equipment shell from the standard bearing pressure. It can be understood that when the deviation value of the current bearing pressure of the inflation and deflation equipment shell from the standard bearing pressure is less than a, the shell of the inflation and deflation equipment is in a reasonable pressure bearing range, and will not adversely affect the air tightness and gas supply efficiency of the inflation and deflation equipment, so adjustment can not be performed. On the contrary, when the deviation value of the current bearing pressure of the inflation and deflation equipment shell from the standard bearing pressure is greater than a, the current bearing pressure of the inflation and deflation equipment shell is too large, which will adversely affect the air tightness and gas supply efficiency of the inflation and deflation equipment, so adjustment is needed.

[0073] It can be seen that the embodiments of the present application can obtain the maximum expected bearing pressure and the minimum expected bearing pressure of the inflation and deflation equipment according to the standard bearing pressure A of the inflation and deflation equipment and the maximum deviation value a of the standard bearing pressure. Specifically, the control device can obtain the maximum expected bearing pressure A+a of the inflation and deflation equipment, and obtain the minimum expected bearing pressure A-a of the inflation and deflation equipment.

[0074] It can be understood that the embodiments of the present application can adjust the maximum deviation value of the standard bearing pressure according to the needs of the actual application scene, for example, the maximum expected bearing pressure of the inflation and deflation equipment can be A+a, and the minimum standard bearing pressure of the inflation and deflation equipment can be A-b, a and b can be the same or different values, which are not limited in the embodiments of the present application.

[0075] Step S205, determining the expected bearing pressure range of the inflation and deflation equipment shell according to the maximum expected bearing pressure and the minimum expected bearing pressure.

[0076] In some possible embodiments, after obtaining the maximum expected bearing pressure and the minimum expected bearing pressure based on the standard bearing pressure of the inflation and deflation equipment, the control device of the embodiments of the present application can take the maximum expected bearing pressure and the minimum expected bearing pressure as the maximum value and the minimum value of the expected bearing pressure range to determine the expected bearing pressure range of the inflation and deflation equipment shell. When adjusting the current bearing pressure of the inflation and deflation equipment shell through the expected bearing pressure range of the inflation and deflation equipment, the control device can avoid frequent adjustment of the inflation and deflation equipment within the tolerance range of the current bearing pressure (i.e. the expected bearing pressure range), thereby reducing the negative impact on the service life of the inflation and deflation equipment.

[0077] For example, according to the above description, assuming that the standard bearing pressure of the inflation and deflation device is A, and the maximum deviation value of the standard bearing pressure is a, the maximum expected bearing pressure of the inflation and deflation device can be A+a, and the minimum expected bearing pressure of the inflation and deflation device can be A-a. At this time, the control device of the embodiment of the application can determine that the expected bearing pressure range of the inflation and deflation device is A+a~A-a.

[0078] It can be understood that when the current bearing pressure of the inflation and deflation device shell is less than the above-mentioned maximum expected bearing pressure and greater than the above-mentioned minimum expected bearing pressure, it indicates that the current bearing pressure of the inflation and deflation device shell at this time is within a reasonable pressure bearing range, that is, the current bearing pressure of the inflation and deflation device shell is not too large or too small, which ensures the good air tightness and gas supply efficiency of the inflation and deflation device.

[0079] In some possible implementations, when the current bearing pressure of the inflation and deflation device shell belongs to the above-mentioned expected bearing pressure range, it can be determined that the shell of the inflation and deflation device is in a reasonable pressure bearing range, which will not adversely affect the air tightness and gas supply efficiency of the inflation and deflation device, and therefore the control device does not need to adjust the current bearing pressure of the inflation and deflation device shell. On the contrary, when the current bearing pressure of the inflation and deflation device shell does not belong to the above-mentioned expected bearing pressure range, it can be determined that the current bearing pressure of the inflation and deflation device shell is too large or too small, which affects the air tightness and gas supply efficiency of the inflation and deflation device, and therefore the control device needs to adjust the bearing pressure of the inflation and deflation device shell.

[0080] In some possible implementations, since the current bearing pressure of the inflation and deflation device shell is related to the internal gas pressure of the inflation and deflation device and the external environmental gas pressure, the current bearing pressure of the inflation and deflation device shell can be adjusted to be within the above-mentioned expected bearing pressure range by adjusting the internal gas pressure of the inflation and deflation device, so as to ensure the good air tightness and gas supply efficiency of the inflation and deflation device. Therefore, the control device of the embodiment of the application can obtain the initial gas pressure inside the inflation and deflation device, and adjust the current bearing pressure of the inflation and deflation device according to the initial gas pressure inside the inflation and deflation device. The initial gas pressure inside the inflation and deflation device can be understood as the internal gas pressure of the inflation and deflation device before adjustment.

[0081] In some possible implementations, the control device of the embodiment of the application can obtain the initial gas pressure inside the inflation and deflation device through the above-mentioned gas pressure sensor.

[0082] It needs to be explained that in the case of a fixed-volume inflation and deflation device, the initial gas pressure inside the inflation and deflation device and the internal pressure of the initial gas pressure acting on the shell of the inflation and deflation device are in a linear proportional relationship. Specifically, the linear proportional relationship between the initial gas pressure of the inflation and deflation device and the internal pressure can be represented by the following formula (1):

[0083]

[0084] Wherein, P represents the internal gas pressure of the inflation and deflation device, i.e. the initial gas pressure mentioned above; F represents the internal pressure of the inflation and deflation device shell, i.e. the pressure of the initial gas pressure acting on the shell; S represents the surface area of the contact surface inside the inflation and deflation device.

[0085] Further, in the case that the external environment gas pressure of the inflation and deflation device is constant, the greater the initial gas pressure inside the inflation and deflation device, the greater the current bearing pressure of the inflation and deflation device shell, and the current bearing pressure of the inflation and deflation device shell and the initial gas pressure of the inflation and deflation device also present a linear proportional relationship. Thus, in the case that the inflation and deflation device is a fixed volume inflation and deflation device, the initial gas pressure of the inflation and deflation device and the current bearing pressure of the inflation and deflation device shell present a linear proportional relationship.

[0086] For ease of understanding, the embodiments of the present application are illustrated by way of example in conjunction with Figure 4 the relationship diagram shown in FIG. 1. Please refer to Figure 4 , Figure 4 the pressure-pressure relationship diagram of the control method of the inflation and deflation device provided by the embodiments of the present application. As shown in Figure 4 , under the standard atmospheric pressure, the relationship between the initial gas pressure P inside the inflation and deflation device and the current bearing pressure F of the shell is shown as a straight line L1. With the linear increase of the initial gas pressure P inside the inflation and deflation device, the current bearing pressure F of the inflation and deflation device shell also linearly increases. Thus, the initial gas pressure P inside the inflation and deflation device and the current bearing pressure F of the inflation and deflation device shell are in a one-to-one corresponding relationship. That is, when the initial gas pressure P inside the inflation and deflation device is different, the corresponding current bearing pressure F of the inflation and deflation device shell is also different.

[0087] Thus, the control device of the embodiments of the present application can adjust the initial gas pressure of the inflation and deflation device to the initial gas pressure corresponding to the standard bearing pressure, so as to make the current bearing pressure of the inflation and deflation device shell equal to the standard bearing pressure. Further, the control device of the embodiments of the present application determines the initial gas pressure of the inflation and deflation device corresponding to the standard bearing pressure of the inflation and deflation device in a linear relationship as the expected bearing gas pressure of the inflation and deflation device.

[0088] It can be understood that the expected bearing gas pressure of the inflation and deflation device is used to represent the size of the initial gas pressure inside the inflation and deflation device corresponding to the standard bearing pressure of the inflation and deflation device shell when the current bearing pressure of the inflation and deflation device shell is equal to the standard bearing pressure in a certain working environment. For example, as shown in Figure 4 , when the standard bearing pressure of the inflation and deflation device is f, according to the linear relationship L1, the corresponding initial gas pressure of the inflation and deflation device can be calculated as Pe1, i.e. the expected bearing gas pressure of the inflation and deflation device is Pe1.

[0089] It can be understood that, as the initial air pressure of the inflation and deflation device has a linear correlation with the current bearing pressure of the inflation and deflation device shell, the control device can adjust the initial air pressure of the inflation and deflation device to the expected bearing air pressure corresponding to the standard bearing pressure, so that the current bearing pressure of the inflation and deflation device shell is equal to the standard bearing pressure. To this end, the control device of the embodiment of the application can obtain the expected bearing air pressure of the inflation and deflation device before adjusting the bearing pressure of the inflation and deflation device shell.

[0090] In some application scenarios, the expected bearing air pressure of the inflation and deflation device can change with the change of the external environment air pressure. For example, when the inflation and deflation device is in a high altitude area, the decrease of the external atmospheric pressure can cause the expected bearing air pressure of the inflation and deflation device to decrease. For example, as shown in FIG. 1, when the inflation and deflation device is in a standard atmospheric pressure, the relationship between the initial air pressure P inside the inflation and deflation device and the current bearing pressure F of the shell is shown as a straight line L1, and the expected bearing air pressure of the inflation and deflation device is Pe1. When the inflation and deflation device is in a high altitude area, the relationship between the initial air pressure P inside the inflation and deflation device and the current bearing pressure F of the shell is shown as a straight line L2, and at this time, the expected bearing air pressure of the inflation and deflation device is reduced from Pe1 to Pe2. When the inflation and deflation device is affected by external force and the external environment air pressure does not change, the expected bearing air pressure of the inflation and deflation device remains the expected bearing air pressure Pe1 in the standard atmospheric pressure, and the relationship between the initial air pressure P inside the inflation and deflation device and the current bearing pressure F of the shell is shown as a straight line L1. Figure 4

[0091] In some possible embodiments, in order to obtain the changed expected bearing air pressure of the inflation and deflation device when the working environment changes, the control device of the embodiment of the application can detect the inflation and deflation device in real time to adjust the initial air pressure of the inflation and deflation device according to the changed expected bearing air pressure of the inflation and deflation device.

[0092] Specifically, when the inflation and deflation device is a fixed volume inflation and deflation device, the relationship between the initial air pressure inside the inflation and deflation device and the current bearing pressure of the inflation and deflation device shell can be represented by the following formula (2):

[0093]

[0094] Wherein, P n represents the initial air pressure inside the inflation and deflation device; f n represents the current bearing pressure of the inflation and deflation device shell; P e represents the expected bearing air pressure of the inflation and deflation device; f represents the standard bearing pressure of the inflation and deflation device.

[0095] ​It is understood that the control device in this application embodiment can obtain the standard withstand pressure f in advance, and obtain the initial air pressure P inside the inflation / deflation device through the aforementioned air pressure sensor. n The current pressure f of the inflation / deflation device housing is obtained through the aforementioned pressure sensor. n Furthermore, the control device in this embodiment can obtain the standard withstand pressure f and the current withstand pressure f of the inflation / deflation device. n The ratio between and the ratio With the expected air pressure P n The product between The expected pressure P to be withstandd by the inflation / deflation equipment is determined. e .

[0096] In some feasible implementations, when the control device in the embodiments of this application obtains the expected pressure range that the inflation / deflation device can withstand, further, since each expected pressure range can correspond to a standard pressure, the control device can find the standard pressure that the inflation / deflation device can withstand by searching the expected pressure range.

[0097] In some feasible implementations, the control device of this application embodiment can also obtain two endpoint values ​​of the expected pressure range, namely the maximum expected pressure and the minimum expected pressure, and determine the average value of the maximum expected pressure and the minimum expected pressure as the standard pressure that the inflation / deflation device can withstand by calculating the average value of the maximum expected pressure and the minimum expected pressure.

[0098] In summary, the control device of this application embodiment can obtain the expected pressure that the inflation / deflation device can withstand after the working environment of the inflation / deflation device changes, by acquiring the initial pressure, current withstand pressure, and standard withstand pressure of the inflation / deflation device at this time, and then determine the expected withstand pressure of the inflation / deflation device based on the correspondence between the expected withstand pressure and the standard withstand pressure inside the inflation / deflation device (e.g., Figure 4 The L1 or L2 in the formula adjusts the initial air pressure inside the inflation / deflation device to the desired pressure, thereby adjusting the current pressure of the inflation / deflation device housing to the standard pressure, thus regulating the current pressure of the inflation / deflation device housing.

[0099] Step S103: Inflate or deflate the inflation / deflation device according to the expected pressure and the initial pressure to adjust the current pressure of the device shell so that the adjusted current pressure is within the expected pressure range.

[0100] In some feasible implementations, as explained above, the expected pressure that the inflation / deflation device can withstand and the standard pressure that the device's housing can withstand are in a one-to-one correspondence under the same working environment. That is, under a certain working environment, when the initial pressure inside the inflation / deflation device equals the expected pressure it can withstand under that working environment, the pressure that the device's housing can withstand is equal to the standard pressure. Therefore, in this embodiment, after obtaining the expected pressure that the inflation / deflation device can withstand, the current pressure that the device's housing can withstand can be adjusted to be equal to the standard pressure by adjusting the initial pressure inside the inflation / deflation device to the expected pressure.

[0101] In some feasible implementations, embodiments of this application can use an external motor and solenoid valve to inflate and deflate the inflation / deflation device, thereby adjusting the initial internal pressure to the desired withstand pressure. For details, please refer to... Figure 5 , Figure 5 This is a schematic diagram of the inflation / deflation device provided in an embodiment of this application. Figure 5 As shown, the inflation / deflation device includes the aforementioned pressure sensor and gas pressure sensor. The 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 inflation / deflation. Furthermore, the device can also be connected to an external gas-consuming device and supply gas to that device.

[0102] It is understandable that when the initial air pressure is lower than the expected bearing pressure, it indicates that the initial air pressure inside the inflation / deflation device is low, resulting in low air supply efficiency. Therefore, it is necessary to increase the initial air pressure of the inflation / deflation device. In this embodiment, an external motor can be controlled to inflate the inflation / deflation device, thereby increasing the initial air pressure inside the device and simultaneously reducing the current bearing pressure. Furthermore, this embodiment uses the aforementioned pressure sensor to detect the initial air pressure inside the inflation / deflation device during the inflation process, and controls the motor to stop inflation when the internal air pressure equals the expected bearing pressure. It is understood that when the internal air pressure of the inflation / deflation device equals the expected bearing pressure, the corresponding current bearing pressure of the inflation / deflation device equals the expected bearing pressure, i.e., it falls within the expected bearing pressure range.

[0103] In other words, in this embodiment of the application, when the initial air pressure is less than the expected bearing air pressure, the motor is controlled to inflate the inflation / deflation device, thereby increasing the initial air pressure inside the inflation / deflation device to the expected bearing air pressure. This increases the current bearing pressure of the inflation / deflation device shell to the range of the expected bearing pressure, ensuring good air supply efficiency of the inflation / deflation device.

[0104] It can be understood that when the initial air pressure is greater than the expected bearing air pressure, the initial air pressure inside the inflating and deflating device is greater, resulting in that the inflating and deflating device bears greater pressure, and thus the initial air pressure of the inflating and deflating device needs to be reduced. The embodiment of the present application can reduce the initial air pressure inside the inflating and deflating device by controlling the external electromagnetic valve to deflate the inflating and deflating device, so as to reduce the current bearing pressure of the inflating and deflating device. At the same time, the embodiment of the present application detects the initial air pressure inside the inflating and deflating device during deflation by the above-mentioned air pressure sensor, and controls the electromagnetic valve to stop deflation when the internal air pressure of the inflating and deflating device is equal to the expected bearing air pressure. It can be understood that in the case that the internal air pressure of the inflating and deflating device is equal to the expected bearing air pressure, the current bearing pressure of the inflating and deflating device is equal to the expected bearing pressure, that is, it belongs to the expected bearing pressure range.

[0105] That is, when the initial air pressure is greater than the expected bearing air pressure, the embodiment of the present application deflates the inflating and deflating device by controlling the electromagnetic valve, so that the initial air pressure inside the inflating and deflating device is reduced to the expected bearing air pressure, thereby reducing the current bearing pressure of the inflating and deflating device to the expected bearing pressure range, and ensuring the good air tightness of the inflating and deflating device.

[0106] In some possible implementations, the inflating and deflating device in the embodiment of the present application can also be inflated and deflated by other inflation units (i.e., the above-mentioned motor) and deflation units (i.e., the above-mentioned electromagnetic valve), and the embodiment of the present application does not make any limitation.

[0107] For the convenience of understanding, the embodiment of the present application will be illustrated in the following content Figure 4 For the convenience of understanding, the embodiment of the present application will be illustrated in the following content Figure 4 , it is assumed that the expected bearing air pressure of the inflating and deflating device is Pe1 when the external environment air pressure is the standard atmospheric pressure, and the corresponding standard bearing pressure is f, and the current bearing pressure of the inflating and deflating device is f. When the inflating and deflating device enters a high-altitude area, due to the decrease of the external environment air pressure, the current bearing pressure of the inflating and deflating device shell is increased from f to fn1, and the expected bearing air pressure of the inflating and deflating device is reduced from Pe1 to Pe2, at this time, the relationship between the initial air pressure P inside the inflating and deflating device and the current bearing pressure F of the shell is shown as a straight line L2. In order to maintain the current bearing pressure of the inflating and deflating device shell within the expected bearing pressure range f1-f2 (f1 is the maximum expected bearing pressure, and f2 is the minimum expected bearing pressure), the control device of the embodiment of the present application can deflate the inflating and deflating device, so that the initial air pressure inside the inflating and deflating device after deflation is reduced from Pe1 to the expected bearing air pressure Pe2. From the above content, since the relationship between the initial air pressure P inside the inflating and deflating device and the current bearing pressure F of the shell is shown as a straight line L2, it is a one-to-one correspondence, and thus when the initial air pressure inside the inflating and deflating device is equal to the expected bearing air pressure Pe2, the current bearing pressure of the inflating and deflating device is equal to the expected bearing pressure, that is, it belongs to the expected bearing pressure range f1-f2.Figure 4 As shown, the current pressure that the corresponding inflation / deflation equipment housing can withstand is equal to the standard pressure f, thereby achieving the adjustment of the current pressure that the inflation / deflation equipment housing can withstand.

[0108] In some application scenarios, such as Figure 4 As shown, assuming the external ambient pressure is standard atmospheric pressure, the expected pressure the inflation / deflation device can withstand is Pe1, the corresponding standard pressure is f, and the current pressure the inflation / deflation device can withstand is f. When an external force causes deformation of the device's casing, the initial pressure Pe1 inside the device increases to Pn, and the current pressure the casing can withstand increases from f to fn2. At this time, the expected pressure the inflation / deflation device can withstand remains Pe1. To maintain the current pressure the casing can withstand within the expected pressure range f1 to f2, the control device in this embodiment can deflate the device, reducing the initial pressure inside from Pn to the expected pressure Pe1. Simultaneously, since the relationship between the initial pressure P inside the device and the current pressure F of the casing is shown by line L1, which is a one-to-one correspondence, when the initial pressure inside the device equals the expected pressure Pe1, as... Figure 4 As shown, the current pressure that the corresponding inflation / deflation device housing can withstand is equal to the standard pressure f, thereby achieving the adjustment of the current pressure that the inflation / deflation device housing can withstand.

[0109] In some application scenarios, assuming the inflation / deflation device has an expected withstand pressure of Pe1 when the external ambient pressure is standard atmospheric pressure, and the corresponding standard withstand pressure is f, and the current withstand pressure of the inflation / deflation device is f. When the inflation / deflation device is affected by external forces and is located at a high altitude, due to the change in the external ambient pressure, the expected withstand pressure of the inflation / deflation device decreases from the expected withstand pressure Pe1 under the aforementioned standard atmospheric pressure to Pe2. The relationship between the initial internal pressure P of the inflation / deflation device and the withstand pressure F of the shell is shown as a straight line L2. At the same time, under the influence of high altitude and external forces, the initial internal pressure of the inflation / deflation device increases from Pe1 to Pn, and the current withstand pressure of the shell increases from f to fn3. In order to maintain the current withstand pressure of the inflation / deflation device shell within the expected withstand pressure range f1 to f2, the control device of this application embodiment can deflate the inflation / deflation device, so that the initial internal pressure of the inflation / deflation device after deflation decreases from Pn to the expected withstand pressure Pe2. From the above, since the relationship between the initial pressure P inside the inflation / deflation device and the current pressure F that the shell can withstand is shown by the straight line L2, which is a one-to-one correspondence, when the initial pressure inside the inflation / deflation device is equal to the desired pressure Pe2, as shown by the straight line L2, Figure 4As shown, the current pressure that the corresponding inflation / deflation device housing can withstand is equal to the standard pressure f, thereby achieving the adjustment of the current pressure that the inflation / deflation device housing can withstand.

[0110] In some feasible implementations, the control device of this application embodiment can pause or continue adjusting the inflation / deflation device according to the following steps. For details, please refer to... Figure 6 , Figure 6 This is another schematic flowchart illustrating the control method for the inflation / deflation device provided in an embodiment of this application. For example... Figure 6 As shown, the control method includes at least the following steps S301-S306. Specifically, in this embodiment, steps S301-S303 are used to obtain the expected and initial pressures of the inflation / deflation device, and the device is inflated / deflated based on these pressures to adjust the current pressure on the device housing. Then, steps S304-S306 determine whether to pause or continue adjusting the inflation / deflation device.

[0111] It should be noted that the specific implementation of steps S301-S303 above, which involves obtaining the expected and initial pressures of the inflation / deflation equipment and inflating / deflation based on these pressures, can be found in the specific implementation of steps S101-S103, and will not be repeated here. Furthermore, the determination of whether to pause or continue adjusting the inflation / deflation equipment may include the following steps:

[0112] Step S304: When the internal air pressure of the inflation / deflation device is detected to reach the expected pressure, the pressure that the housing of the inflation / deflation device can withstand is tested.

[0113] In some feasible implementations, when the control device of this application inflates or deflates the inflation / deflation device according to the expected pressure and the initial pressure to adjust the current pressure bearing capacity of the inflation / deflation device housing, as described above, when the pressure sensor detects that the internal pressure of the inflation / deflation device has reached the expected pressure, the control motor or solenoid valve stops the inflation / deflation process. At this time, if the external environment remains unchanged and the inflation / deflation device is not affected by external forces, then when the internal pressure of the inflation / deflation device equals the expected pressure, the current pressure bearing capacity of the inflation / deflation device housing is equal to the standard pressure bearing capacity. That is, the current pressure bearing capacity of the inflation / deflation device housing falls within the expected pressure bearing capacity range, and the pressure bearing capacity of the inflation / deflation device housing is reasonable, without adversely affecting the airtightness and gas supply efficiency of the inflation / deflation device.

[0114] It needs to be explained that, in the process of inflating and deflating the inflating and deflating device according to the expected bearing air pressure and the initial air pressure, if the external environment changes or the inflating and deflating device is affected by external force, the expected bearing air pressure of the inflating and deflating device will change. However, the initial air pressure inside the inflating and deflating device is still adjusted to the expected bearing air pressure before the change in the inflating and deflating process. It can be understood that, since the expected bearing air pressure of the inflating and deflating device has changed at this time, the expected bearing air pressure before the change no longer corresponds to the standard bearing pressure of the inflating and deflating device. Therefore, when the initial air pressure inside the inflating and deflating device is adjusted to the expected bearing air pressure before the change, the current bearing pressure of the inflating and deflating shell is not equal to the standard bearing pressure, that is, the current bearing pressure of the inflating and deflating device shell is not within the above-mentioned expected bearing pressure range, and the bearing pressure of the inflating and deflating device shell is too large or too small, which has an adverse effect on the air tightness and gas supply efficiency of the inflating and deflating device.

[0115] In some possible implementations, as can be known from the above, in the process of inflating and deflating the inflating and deflating device according to the expected bearing air pressure and the initial air pressure, if the external environment changes or the inflating and deflating device is affected by external force, the expected bearing air pressure of the inflating and deflating device will change. In order to update the expected bearing air pressure of the inflating and deflating device in time after the expected bearing air pressure of the inflating and deflating device changes, and to re-adjust the initial air pressure inside the inflating and deflating device, the control device of the present application can continue to detect the bearing pressure of the inflating and deflating device shell after pausing the inflation and deflation of the inflating and deflating device.

[0116] It can be understood that, after the control device detects the bearing pressure of the inflating and deflating device shell, if the bearing pressure of the inflating and deflating device shell belongs to the above-mentioned expected bearing pressure range of the inflating and deflating device, it indicates that the bearing pressure of the inflating and deflating device shell is reasonable, and will not have an adverse effect on the air tightness and gas supply efficiency of the inflating and deflating device, and re-adjustment is not needed. On the contrary, if the bearing pressure of the inflating and deflating device shell does not belong to the above-mentioned expected bearing pressure range of the inflating and deflating device, it indicates that the expected bearing air pressure of the inflating and deflating device has changed, resulting in that the bearing pressure of the inflating and deflating device shell is too large or too small, which has an adverse effect on the air tightness and gas supply efficiency of the inflating and deflating device, and re-adjustment is needed.

[0117] Step S305, when it is detected that the bearing pressure of the inflating and deflating device shell changes, the changed bearing pressure of the inflating and deflating device shell is obtained.

[0118] In some possible implementation manners, when the control device detects that the bearing pressure of the gas charging and discharging device shell changes, the bearing pressure of the gas charging and discharging device shell needs to be re-adjusted. Further, as known from the foregoing, before the bearing pressure of the gas charging and discharging device shell is re-adjusted, the expected bearing air pressure of the gas charging and discharging device at this time (that is, the changed expected bearing air pressure) can be obtained, so as to re-adjust the gas charging and discharging device according to the changed expected bearing air pressure.

[0119] Specifically, the control device in the embodiment of the present application can obtain the changed expected bearing air pressure of the gas charging and discharging device according to the changed bearing pressure of the gas charging and discharging device, the initial air pressure in the gas charging and discharging device, and the standard bearing pressure. For specific implementation manners, reference can be made to the specific implementation manners of step S102, which will not be repeated here.

[0120] Step S306, continue to charge and discharge the gas charging and discharging device according to the changed bearing pressure, so as to adjust the changed bearing pressure of the gas charging and discharging device shell, so that the adjusted bearing pressure belongs to the expected bearing pressure range.

[0121] In some possible implementation manners, after the control device in the embodiment of the present application obtains the changed expected bearing air pressure of the gas charging and discharging device according to the changed bearing pressure of the gas charging and discharging device shell, the initial air pressure in the gas charging and discharging device, and the standard bearing pressure, further, the control device can continue to charge and discharge the gas charging and discharging device according to the changed expected bearing air pressure of the gas charging and discharging device and the initial air pressure in the gas charging and discharging device, so as to adjust the changed bearing pressure of the gas charging and discharging device shell, so that the adjusted bearing pressure belongs to the expected bearing pressure range.

[0122] Specifically, for specific implementation manners in which the control device in the embodiment of the present application continues to charge and discharge the gas charging and discharging device according to the changed expected bearing air pressure and the initial air pressure in the gas charging and discharging device, reference can be made to the specific implementation manners of step S103, which will not be repeated here.

[0123] In some possible implementation manners, for the convenience of understanding, the control method for the gas charging and discharging device provided in the embodiment of the present application will be illustrated below in combination with Figure 7 Specifically, reference can be made to Figure 7 , Figure 7 Another flowchart of the control method for the gas charging and discharging device provided in the embodiment of the present application. Figure 7The control method shown includes at least the following steps S401-S408. In this embodiment, the control device obtains the expected pressure range of the charging / discharging device housing in step S401, and obtains the current pressure of the charging / discharging device housing in step S402. Further, it can determine whether the current pressure of the charging / discharging device falls within the expected pressure range in step S403. It is understood that if the current pressure of the charging / discharging device falls within the expected pressure range, it indicates that the pressure resistance of the charging / discharging device housing is reasonable and will not adversely affect the airtightness and gas supply efficiency of the charging / discharging device. In this embodiment, the control device completes the adjustment of the charging / discharging device in step S408. If the current pressure of the charging / discharging device does not fall within the expected pressure range, it indicates that the pressure resistance of the charging / discharging device housing is too high or too low, which will adversely affect the airtightness and gas supply efficiency of the charging / discharging device. In this case, the control device needs to adjust the charging / discharging device.

[0124] Specifically, such as Figure 7 As shown, when the current pressure of the inflation / deflation device is not within the expected pressure range, the control device of this embodiment obtains the initial pressure and the expected pressure inside the inflation / deflation device through step S404. Further, in step S405, it is determined whether the initial pressure is greater than the expected pressure. If the initial pressure is greater than the expected pressure, the control device of this embodiment deflates the inflation / deflation device through step S406 to reduce the current pressure on the device's casing and ensure good airtightness. Conversely, if the initial pressure is less than the expected pressure, the control device of this embodiment inflates the inflation / deflation device through step S407 to increase the current pressure on the device's casing and ensure good gas supply efficiency.

[0125] It should be noted that the specific implementation of steps S401-S408 for adjusting the current pressure of the inflation / deflation device can be found in the specific implementation of steps S101-S103, and will not be repeated here in the embodiments of this application.

[0126] Understandably, after the control equipment inflates or deflates the inflation / deflation device based on the expected and initial pressures to adjust its current pressure tolerance, it further determines whether the adjusted current pressure tolerance falls within the expected pressure tolerance range. If the adjusted current pressure tolerance falls within the expected pressure tolerance range, the adjustment of the inflation / deflation device is completed. Conversely, if the adjusted current pressure tolerance falls outside the expected pressure tolerance range, such as... Figure 7As shown, the adjustment of the inflation and deflation device is continued according to the above steps until the adjusted current bearing pressure belongs to the expected bearing pressure range, and the adjustment of the inflation and deflation device is completed.

[0127] In the present application, when the inflation and deflation device is a fixed-volume inflation and deflation device, the control device can pre-acquire the expected bearing pressure range of the inflation and deflation device shell when the inflation and deflation device works in a stable state, which refers to the bearing pressure range of the inflation and deflation device shell when the inflation and deflation device has a relatively high gas supply efficiency and a relatively good air tightness. Further, the control device can continuously detect the bearing pressure of the inflation and deflation device shell in real time to obtain the current bearing pressure of the inflation and deflation device shell. When the current bearing pressure of the inflation and deflation device does not belong to the expected bearing pressure range, it indicates that the current bearing pressure of the inflation and deflation device is too large or too small. At this time, the control device can acquire the initial gas pressure inside the inflation and deflation device, and dynamically determine the expected bearing gas pressure of the inflation and deflation device shell according to the initial gas pressure, the expected bearing pressure range and the current bearing pressure. Further, the inflation and deflation of the inflation and deflation device is performed according to the expected bearing gas pressure and the initial gas pressure of the inflation and deflation device to adjust the current bearing pressure of the inflation and deflation device shell, so that the adjusted current bearing pressure belongs to the expected bearing pressure range. In this way, it can be avoided that the bearing pressure of the inflation and deflation device shell is too large or too small, so as to ensure the good air tightness and gas supply efficiency of the inflation and deflation device and prolong the service life of the inflation and deflation device. At the same time, the surface bearing pressure of the inflation and deflation device shell (i.e. the current bearing pressure) is taken as the relationship point (i.e. the contact point) between the internal and external gas pressures, i.e. the surface bearing pressure reflects the relationship between the internal gas pressure of the inflation and deflation device and the external environmental gas pressure, and the surface bearing pressure is taken as the control variable to control the bearing pressure of the inflation and deflation device shell to maintain in the expected bearing pressure range, thereby improving the control accuracy of the inflation and deflation device. It is not necessary to measure the external environmental gas pressure, and the problem of low control accuracy of the control mode based on a single environmental gas pressure can be avoided.
