Description

Technical Field

[0001] The present application relates to the technical field of air film pressurization, and in particular to an inflation pressurization control method, system, and medium for a double-layer air film system. Background Art

[0002] An air dome structure uses a special membrane material as its outer shell, coupled with intelligent electromechanical equipment to inflate and pressurize the interior of the shell, thereby supporting the shell and creating a large internal storage space. To improve the spatial environment of the air dome structure, the outer shell is designed with a double membrane. This double membrane defines a sandwich area, which acts as a supporting rib, providing physical protection for the air dome structure and regulating the spatial environment.

[0003] At present, the air membrane structure with a double-layer membrane uses a fan to inflate and pressurize the interior of the air membrane structure and the interlayer area. Since the internal environment of the air membrane structure is affected by various factors, the air pressure changes frequently, making the air pressure in the interlayer area unstable. The fan is prone to over-pressurize or under-pressurize the interlayer area, affecting the spatial physical properties and structural safety of the air membrane structure, which is not conducive to the effective and safe operation of the air membrane. Summary of the Invention

[0004] In response to the shortcomings in the existing technology, this application provides an inflation and pressurization control method for a double-layer air membrane system. By comparing the air pressure in the interlayer area and the air pressure in the large space inside the double-layer air membrane system, the inflation pressure state of the double-layer air membrane is adjusted based on the air pressure comparison relationship, thereby adjusting and optimizing the physical environment inside the air membrane.

[0005] Based on the above-mentioned inflation and pressurization control method of the double-layer air membrane system, a double-layer air membrane system and a computer-readable storage medium are also proposed.

[0006] A first aspect of the present application provides an inflation and pressurization control method for a double-layer air membrane system, which is applied to the double-layer air membrane system. The double-layer air membrane system includes a substrate, an outer membrane installed on the substrate and defining an internal space together with the substrate, an inner membrane provided on the inner side of the outer membrane and defining a sandwich unit together with the outer membrane, a fan assembly for inflating and pressurizing the sandwich unit, and a valve assembly connecting the sandwich unit to the outside world. The inflation and pressurization control method for the double-layer air membrane system includes the following steps:

[0007] Determine the operating state of the double-layer air film system, the operating state including an active control state and an automatic control state; if in the active control state, obtain an active control instruction, and control the working state of the fan assembly and / or the valve assembly based on the active control instruction; if in the automatic control state, obtain the air pressure information and temperature information of the double-layer air film system, and control the working state of the fan assembly and / or the valve assembly based on the air pressure information and the temperature information; wherein, the working state includes an open state and a closed state.

[0008] Through the above technical solution, after obtaining the operating status information of the double-layer air membrane system, it is determined whether it is in an active control state or an automatic control state. In the active control state, the operator mainly controls the fan assembly and valve assembly according to actual production needs. In the automatic control state, the identification module, judgment module and control module of the double-layer air membrane system cooperate with each other, and automatically control the actions of the fan assembly and valve assembly based on the air pressure information and temperature information of the double-layer air membrane system; through the cooperation of the two control methods, the controllability of the inflation and pressurization of the double-layer air membrane system is ensured. Among them, the automatic control mode automatically monitors the internal space air pressure, internal space temperature and interlayer unit air pressure, which improves the accuracy of inflation and pressurization, thereby improving the safety of the use of the double-layer air membrane system.

[0009] In some embodiments, after the step of determining the operating status of the double-layer air membrane system, the step also includes: identifying the connection status of the double-layer air membrane system and the remote control end; if it is in a non-remote connection state, controlling the fan assembly and the valve assembly to the closed state; if it is in a remote connection state, performing subsequent control steps based on the operating status.

[0010] Through the above technical solution, the double-layer air film system needs to first determine whether it is connected to the remote control terminal, and decide whether to perform subsequent inflation and pressurization steps based on the judgment result. When the double-layer air film system is connected to the remote control terminal, it means that there is an operator to monitor it. If an emergency occurs in the double-layer air film system, the operator can adjust the working status of the fan assembly and / or valve assembly in time, thereby improving the fault tolerance of the double-layer air film system and further improving safety.

[0011] In some embodiments, the air pressure information includes the first air pressure of the internal space and the second air pressure of the interlayer unit. The controlling the working state of the fan assembly and / or the valve assembly based on the air pressure information and the temperature information includes the steps of: judging whether the second air pressure is greater than or equal to the first air pressure; if the second air pressure is greater than or equal to the first air pressure, or the second air pressure is less than the first air pressure and the absolute value of the second air pressure minus the first air pressure is less than the error preset value, judging that the air pressure information is normal and proceeding to the next step; if the second air pressure is less than the first air pressure and the absolute value of the second air pressure minus the first air pressure is greater than the error preset value, judging that the air pressure information is wrong and returning to the previous step; judging whether the first air pressure is higher than the pressure limit preset value; if the first air pressure is greater than or equal to the pressure limit preset value, controlling the fan assembly to the closed state; if the first air pressure is less than the pressure limit preset value, controlling the working state of the fan assembly and / or the valve assembly based on the difference between the second air pressure and the first air pressure.

[0012] Through the above technical solution, under normal circumstances, after the double-layer air membrane system is formed, the second air pressure is greater than or equal to the first air pressure; when the second air pressure is less than the first air pressure and the absolute difference exceeds the error value of the sensor, it proves that the sensor is not installed in place or is out of the detection area, and the data detected by the sensor is incorrect. By comparing the size relationship between the second air pressure and the first air pressure, the sensor failure can be checked in time to ensure the accuracy of the data, thereby ensuring the accuracy of the subsequent control steps, and avoiding irreversible losses in the inflation and pressurization process of the double-layer air membrane system due to inaccurate data; in addition, when the second air pressure is pressurized to a certain pressure, the connection between the air ribs in the sandwich unit will burst, causing damage to the air ribs. Since the second air pressure is greater than or equal to the first air pressure under normal circumstances as mentioned above, when it is detected that the first air pressure exceeds the preset pressure limit value, it is necessary to shut down the fan assembly in time to avoid the second air pressure increasing to the extent that the air ribs will burst, thereby improving the safety of the sandwich unit being inflated and pressurized again.

[0013] In some embodiments, the control of the working state of the fan assembly and / or the valve assembly based on the difference between the second air pressure and the first air pressure includes the steps of: judging the size relationship between the difference and the first preset value, the second preset value, and the third preset value; if the difference is less than or equal to the first preset value, controlling the fan assembly to the open state, and returning to the step of "judging whether the second air pressure is greater than or equal to the first air pressure"; if the difference is greater than the first preset value and less than the second preset value, controlling the fan assembly to maintain the current working state, and returning to the step of "judging whether the second air pressure is greater than or equal to the first air pressure"; if the difference is greater than or equal to the second preset value and less than the third preset value, controlling the fan assembly and the valve assembly to both be in the closed state; if the difference is greater than or equal to the third preset value, controlling the valve assembly to the open state, and returning to the step of "judging whether the second air pressure is greater than or equal to the first air pressure".

[0014] Through the above technical solution, under normal circumstances, after the double-layer air membrane system is formed, the second air pressure is greater than or equal to the first air pressure; when the difference between the second air pressure and the first air pressure is less than or equal to the first preset value, it means that the air pressure of the sandwich unit is insufficient to achieve the supporting effect, and the fan assembly needs to be turned on to inflate and pressurize the sandwich unit. After the fan assembly is turned on, the process returns to the above steps to cycle; when the difference is greater than the first preset value and less than the second preset value, it means that the air pressure of the sandwich unit is still insufficient to achieve the supporting effect, and the fan assembly is kept turned on, and the inflation and pressurization are continued, and the process returns to the above steps to continue the cycle; When the difference is greater than or equal to the second preset value and less than the third preset value, it means that the air pressure of the interlayer unit has a supporting effect, and the fan assembly is closed. If the valve assembly is in the open state, the valve assembly is closed at the same time to maintain the pressure of the interlayer unit; when the difference is greater than or equal to the third preset value, it means that the air pressure of the interlayer unit exceeds the safety value, and the valve assembly needs to be opened for pressure relief, and the above steps are returned to the cycle; the inflation and pressurization timing of the fan assembly and the exhaust and pressure relief timing of the valve assembly are controlled, which effectively avoids the problem of excessive or insufficient inflation and pressurization of the interlayer unit, and further improves safety.

[0015] In some embodiments, controlling the working state of the fan assembly and / or the valve assembly based on the air pressure information and the temperature information also includes the steps of: determining whether the temperature of the internal space is greater than a preset temperature; if the temperature is greater than the preset temperature, controlling the valve assembly to the open state, and returning to the step of "determining whether the second air pressure is greater than or equal to the first air pressure"; if the temperature is less than or equal to the preset temperature, controlling the valve assembly to the closed state.

[0016] Through the above technical solution, when the temperature of the internal space is greater than the preset temperature, it means that the internal space needs to be cooled, and the exhaust is cooled by opening the valve assembly; when the temperature of the internal space is less than or equal to the preset temperature, it means that the temperature of the internal space has dropped to an appropriate range, and the valve assembly needs to be closed to avoid excessive pressure relief of the interlayer unit; by detecting the temperature of the internal space and controlling the working state of the valve assembly, the temperature control of the double-layer air film system is achieved. Since temperature affects air pressure, lowering the temperature further improves the accuracy of air pressure control.

[0017] In some embodiments, controlling the valve component to be in the open state has a higher priority than controlling the valve component to be in the closed state.

[0018] Through the above technical solution, the pressure relief and temperature reduction of the interlayer unit can be achieved in time, thereby avoiding excessive pressurization of the interlayer unit or excessive temperature of the internal space, thereby improving safety.

[0019] In some embodiments, before the step of determining the operating status of the double-layer air membrane system, the step is also included: determining whether the internal space is in an inflated and pressurized state; if it is in an inflated and pressurized state, executing the subsequent steps; if it is in a non-inflated and pressurized state, looping the previous step until it is identified that the double-layer air membrane system is in an inflated and pressurized state, and executing the subsequent steps.

[0020] Through the above technical solution, it is prioritized to determine whether the double-layer air membrane system needs to be inflated and pressurized again. Since the double-layer air membrane system only needs to turn on the fan assembly during the initial inflation and pressurization, and inflate and pressurize to a predetermined air pressure value, if this process uses the complete control method of this application, the efficiency of the initial inflation and pressurization will be reduced to a certain extent. For this reason, the above technical solution effectively improves the inflation and pressurization efficiency of the double-layer air membrane system.

[0021] The second aspect embodiment of the present application provides a double-layer air membrane system, which is used to implement the control method of the double-layer air membrane system of the first aspect embodiment of the present application. The double-layer air membrane system also includes: a substrate; an outer membrane, which is arranged on the substrate and together with the substrate defines an internal space; an inner membrane, which is arranged on the side of the outer membrane close to the internal space and together with the outer membrane defines a sandwich unit; a fan assembly, which is used to inflate and pressurize the sandwich unit; a valve assembly, which is used to connect the sandwich unit with the outside world; and a control assembly, which is used to obtain the air pressure information and the temperature information of the double-layer air membrane system, and control the working status of the fan assembly and the valve assembly based on the air pressure information and the temperature information.

[0022] The above technical solution can solve the technical problems of the first embodiment of the present application and has all its beneficial effects, which will not be repeated here.

[0023] In some embodiments, the interlayer unit has at least one, and the interlayer unit has at least one air rib. When it contains at least two or more air ribs, the air ribs are interconnected; the fan assembly includes at least one fan, and at least one air supply pipe for connecting the fan and the interlayer unit; the valve assembly includes an exhaust valve; wherein, the fan can supply air to the interlayer unit through the air supply pipe, and the exhaust valve can discharge the gas in the interlayer unit.

[0024] Through the above technical solution, the fan can be set in the internal space or outside the air membrane structure, so that multiple fans can supply air to multiple mezzanine units through one air supply pipe; or multiple fans can supply air to multiple mezzanine units through air supply pipes respectively; effectively improving the air supply efficiency.

[0025] The third embodiment of the present application provides a computer-readable storage medium storing computer-executable instructions, wherein the computer-executable instructions are used to execute the control method of the double-layer air film system of the first embodiment of the present application.

[0026] The above technical solution can solve the technical problems of the first embodiment of the present application and has all its beneficial effects, which will not be repeated here.

[0027] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1 To the attached Figure 3 A double-layer air membrane system according to an embodiment of the second aspect of the present application is described.

[0040] Reference Figure 1 and Figure 2 As shown, the double-layer air membrane system of this embodiment includes a base 1, an outer membrane 2 installed on the base 1 and defining an internal space 3 together with the base 1, an inner membrane 4 arranged on the inner side of the outer membrane 2 and defining a sandwich unit 5 together with the outer membrane 2, a fan assembly 6 for inflating and pressurizing the sandwich unit 5, and a valve assembly 9 for connecting the sandwich unit 5 with the outside world.

[0041] It is understood that the base 1 is a supporting structure made of concrete or composite materials. The edge of the outer membrane 2 is mounted on the base 1 and fixed by fasteners such as bolts. The outer membrane 2, the bottom surface, and the base 1 surround an internal space 3 for storage and other purposes. The inner membrane 4 is arranged on the side of the outer membrane 2 close to the internal space 3. The inner membrane 4 has multiple pieces and is fixed to the outer membrane 2 to form multiple sandwich units 5. The sandwich units 5 are air-ribbed structures with a supporting function, wherein each sandwich unit 5 is further divided into multiple air ribs, and the multiple air ribs of each sandwich unit 5 are connected. The fan assembly 6 includes a fan 8 and an air supply pipe 7, and the valve assembly 9 includes an exhaust valve 11.

[0042] It is understandable that if Figure 1As shown, the fan assembly 6 includes a fan 8 and an air supply pipe 7. The fan 8 is connected to the air supply pipe 7. The air supply pipe 7 has multiple air outlets, and the air outlets are connected to the interlayer units 5. After the fan 8 is started, it supplies air to the air supply pipe 7, and then supplies air to the multiple interlayer units 5. For example, in some embodiments, the fan assembly 6 may include multiple fans 8 and an air supply pipe 7. The multiple fans form a fan module. The fan module is connected to the air supply pipe 7. The air supply pipe 7 is connected to the multiple interlayer units 5 through the multiple air outlets. For another example, in some embodiments, the fan assembly 6 may include multiple fans 8 and an air supply pipe 7. The multiple fans 8 are connected in parallel to the air supply pipe 7. The multiple fans 8 supply air to different positions of the air supply pipe 7, and then supply air to the multiple interlayer units 5 through the multiple air outlets. For another example, in some embodiments, the fan assembly 6 may include multiple fans 8 and multiple air supply pipes 7, and the multiple fans 8 supply air to the multiple interlayer units 5 through the multiple air supply pipes 7, that is, the number of fans 8, air supply pipes 7, and interlayer units corresponds to each other. For another example, in some embodiments, the fan assembly 6 includes one fan 8 and multiple air supply pipes 7, and the multiple air supply pipes 7 are connected in parallel to the fan 8. The air supply pipes 7 can correspond to the number of interlayer units 5, or one air supply pipe 7 corresponds to multiple interlayer units 5, or one interlayer unit 5 corresponds to multiple air supply pipes 7. In addition to the embodiments listed above, the number of fans 8 and the number of air supply pipes 7 can also be set according to actual production needs.

[0043] It is understandable that if Figure 1 As shown, there are multiple exhaust valves 11, corresponding to the number of sandwich units 5. Each sandwich unit 5 is exhausted through an exhaust valve 11. For example, in some embodiments, one exhaust valve 11 can connect to two or more sandwich units 5 through a pipeline. For another example, in some embodiments, one sandwich unit 5 can be equipped with multiple exhaust valves 11. In addition to the embodiments listed above, the relationship between the number of exhaust valves 11 and sandwich units 5 can also be set according to actual production requirements.

[0044] It should be noted that internal space 3 is also equipped with an exhaust structure and an air inflation device. Air is supplied to internal space 3 by its own air inflation device, which is normally kept open. When blower 8 is operating, it delivers air to air supply pipe 7, which controls air inlet valve 10 and exhaust valve 11 to inflate, maintain pressure, or exhaust and release pressure in interlayer unit 5.

[0045] It should be noted that the valve assembly 9 can be opened in two states: fully open and partially open. For example, if the interlayer unit 5 needs to be ventilated quickly, the valve assembly 9 can be fully opened to facilitate rapid exchange of air within the interlayer unit 5. When the interlayer unit 5 is in the process of ventilating or has completed ventilating, the valve assembly 9 can adaptively adjust its opening according to the actual air pressure environment.

[0046] It should be noted that in some specific embodiments, each interlayer unit 5 may be provided with only one or two air ribs, without limitation. When two or more air ribs are provided, the air ribs within the same interlayer unit 5 may or may not be connected. If they are not connected, the number of inlet valves 10 and exhaust valves 11 may be increased to facilitate inflation and exhaust of the air ribs. Furthermore, the interlayer units 5 may also be provided with interconnections, depending on actual production requirements.

[0047] Reference Figure 3 As shown, the double-layer air film system of this embodiment further includes a control component 12. The control component 12 includes multiple types of sensors 13, a memory 14, a processor 15, and a control program stored in the memory 14 and executable on the processor 15. The processor 15 executes the control program to implement the control method of the first embodiment of the present application.

[0048] It will be appreciated that sensor 13 is used to obtain information about the air pressure and temperature of the double-layer air membrane system. For example, the first air pressure of interior space 3, the second air pressure of interlayer unit 5, and the temperature of interior space 3. Processor 15 analyzes this information acquired by sensor 13 based on a control program and, based on the analysis results, outputs control instructions to control the operation of fan assembly 6 and valve assembly 9. Analysis of the information acquired by sensor 13 includes, but is not limited to, determining the operating status of the double-layer air membrane system, determining the working status of fan assembly 6 and valve assembly 9, and comparing the air pressure and temperature information with preset data.

[0049] It should be noted that the memory 14, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs, such as the inflation and pressurization control method for a double-layer air membrane system according to the first embodiment of the present application. The processor 15 retrieves the control program stored in the memory 14 and executes it, thereby implementing the inflation and pressurization control method for a double-layer air membrane system according to the first embodiment of the present application.

[0050] In addition, the memory 14 may include a program storage area and a data storage area, wherein the program storage area may store an operating system and application programs required for at least one function; the data storage area may store data required to execute the inflation and pressurization control method of the double-layer air membrane system of the first embodiment of the present application, etc. In addition, the memory 14 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, or other non-volatile solid-state storage device. In some specific embodiments, the memory 14 may optionally include a memory remotely located relative to the processor 15, and these remote memories may be connected to the terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0051] in addition, Figure 3 The control assembly 12 shown in the figure does not constitute a limitation on the operation of the control assembly 12, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0052] The following is combined with Figure 4 To the attached Figure 10 The inflation and pressurization control method of a double-layer air membrane system according to the first embodiment of the present application is described.

[0053] Reference Figure 4 As shown, in order to improve the precise control of the fan assembly 6 and the valve assembly 9 during the inflation and pressurization process and avoid overcharging or undercharging of the air pressure, the inflation and pressurization control method of this embodiment includes but is not limited to the following steps:

[0054] S1. Determine the operating state of the double-layer air film system, which includes an active control state and a passive control state;

[0055] S2. If in the active control state, obtain an active control instruction, and control the working state of the fan assembly 6 and / or the valve assembly 9 based on the active control instruction;

[0056] S3. If in the passive control state, obtain the air pressure information and temperature information of the double-layer air film system, and control the working state of the fan component 6 and / or valve component 9 based on the air pressure information and temperature information, wherein the working state includes the open state and the closed state.

[0057] It can be understood that, for step S1 and step S2, the operator manually issues control instructions in the active control state. For example, the operator inputs instructions to open the fan assembly 6 and the valve assembly 9 from the control terminal, and the control assembly 12 transmits the control instructions to the fan assembly 6 and the valve assembly 9, and the fan assembly 6 switches to the open state and the valve assembly 9 switches to the open state.

[0058] It can be understood that for step S1 and step S3, in the passive control state, the control component 12 controls the action of the fan component 6 and / or the valve component 9 based on the control program. For example, the sensor 13 obtains the first air pressure of the internal space 3 and the second air pressure of the mezzanine space, and transmits the first air pressure and the second air pressure to the memory 14. The processor 15 determines that the double-layer air membrane system needs to be inflated and pressurized based on the first air pressure information and the second air pressure information of the memory 14. The processor 15 outputs an instruction to open the fan component 6 to the fan component 6 and outputs an instruction to close the valve component 9 to the valve component 9. The fan component 6 switches to the open state and the valve component 9 switches to the closed state.

[0059] Active and passive control work together to enhance the controllability of the double-layer air membrane system. In automatic control mode, the double-layer air membrane system automatically monitors the air pressure in the internal space 3 and the interlayer unit 5, improving inflation accuracy and preventing over- or under-inflation of the internal space 3 and interlayer unit 5, thus preventing damage to the double-layer membrane system and improving safety.

[0060] Reference Figure 5 As shown, in order to avoid unmanned operation when an emergency occurs in the double-layer air film system in the passive control state, after determining the operating state of the fan assembly 6, this embodiment also includes but is not limited to the following steps:

[0061] S4, identifying the connection status between the double-layer air film system and the remote control terminal;

[0062] S5. If it is in a non-remote connection state, control the fan assembly 6 and the valve assembly 9 to be in a closed state. If it is in a remote connection state, perform subsequent control steps based on the operating state.

[0063] It is understandable that when the double-layer air film system detects that it is not connected to a remote terminal, it indicates that the double-layer air film system cannot be safely monitored in this state. For example, if the first air pressure and temperature of the internal space 3 are too high, the second air pressure of the interlayer unit 5 is too low, and the air ribs of the interlayer unit 5 are not inflated, the heat exchange efficiency is low (i.e., the heat dissipation efficiency of the air flowing through the air ribs is low). If the fan assembly 6 and valve assembly 9 continue to operate without a remote terminal, it is easy to cause the double-layer air film system to fail. Determining whether the double-layer air film system is connected to a remote terminal (i.e., whether it is being monitored) before performing subsequent inflation and pressurization operations is safer. Connecting to a remote terminal allows operators to respond to emergencies promptly.

[0064] Reference Figure 6 As shown, this embodiment provides a specific implementation method for controlling the fan assembly 6 and / or the valve assembly 9 based on air pressure information and temperature information, wherein the air pressure information includes the first air pressure of the internal space 3 and the second air pressure of the sandwich unit 5. The above specific implementation method includes but is not limited to the following steps:

[0065] S300, determining whether the second air pressure is greater than or equal to the first air pressure;

[0066] S301: If the second air pressure is greater than or equal to the first air pressure, or if the second air pressure is less than the first air pressure and the absolute value of the second air pressure minus the first air pressure is less than the preset error value, determine that the air pressure information is normal and proceed to the next step;

[0067] S302: If the second air pressure is lower than the first air pressure and the absolute value of the second air pressure minus the first air pressure is greater than the preset error value, it is determined that the air pressure information is incorrect, and the process returns to the previous step.

[0068] S310, determining whether the first air pressure is higher than a preset pressure limit value;

[0069] S311, if the first air pressure is greater than or equal to the preset pressure limit value, control the fan assembly 6 to be in a closed state;

[0070] S312: If the first air pressure is less than the preset pressure limit value, control the working state of the fan assembly 6 and / or the valve assembly 9 based on the difference between the second air pressure and the first air pressure.

[0071] It is understood that in steps S300, S301, and S302, after the double-layer air membrane system is formed, the second air pressure is normally greater than or equal to the first air pressure, allowing the sandwich unit 5 to expand against the air pressure in the internal space 3. If the second air pressure is less than the first air pressure and the absolute difference exceeds the sensor's error (i.e., the preset error), the air pressure information obtained by the sensor is inaccurate, for example, due to the sensor being improperly installed or out of the detection area, resulting in the second air pressure being lower than the first. By comparing the first and second air pressures, a sensor fault can be roughly assessed.

[0072] For example, if the preset error value is set to 10Pa, when the absolute value of the second air pressure minus the first air pressure is greater than 10Pa, it indicates that the air pressure information obtained by sensor 13 has a large error and sensor 13 needs to be replaced. If an error in the air pressure information is detected, the system returns to the previous step and repeatedly determines the difference between the first and second air pressures until the detected air pressure information meets the error range. Only then will the next step be performed. This allows for timely warning information to be issued after determining that the air pressure information has an error, facilitating maintenance by the operator and ensuring the accuracy of subsequent control steps.

[0073] It should be noted that the preset error value is set based on actual production requirements. Specifically, if the difference between the first and second air pressures is too large, it will affect the logical judgment of subsequent steps in the control method and reduce the accuracy of the judgment. Therefore, an error judgment value is set in advance. For example, the preset error value can also be set to 30Pa, 40Pa, 50Pa, etc.

[0074] It is understandable that, in steps S310, S311, and S312, when the second air pressure is increased to a certain level, the connections between the air ribs within the interlayer unit 5 will burst, causing damage to the double-layer air membrane system. Since the second air pressure is normally greater than or equal to the first air pressure, when it is detected that the first air pressure exceeds the preset pressure limit value, the fan assembly 6 needs to be promptly shut down to prevent the second air pressure from increasing to a level that would damage the double-layer air membrane system, thereby improving the safety of re-inflation and pressurization of the interlayer unit 5. For example, the preset pressure limit value can be 400Pa. When the first pressure is greater than or equal to 400Pa, the fan assembly 6 needs to be promptly shut down or maintained in a closed state, and the internal space 3 needs to be properly vented and depressurized. When the first pressure is less than 400Pa, the subsequent re-inflation and pressurization control steps will be performed.

[0075] Reference Figure 7 As shown, this embodiment provides a specific implementation method for controlling the working state of the fan assembly 6 and / or the valve assembly 9 based on the difference between the second air pressure and the first air pressure, including but not limited to the following steps:

[0076] S6. Determine the magnitude relationship between the difference value and the first preset value, the second preset value, and the third preset value;

[0077] S610: If the difference is less than or equal to the first preset value, the fan assembly 6 is controlled to be in the on state, and the process returns to the step of "determining whether the second air pressure is greater than or equal to the first air pressure";

[0078] S620: If the difference is greater than the first preset value and less than the second preset value, the fan assembly 6 is controlled to maintain the current working state, and the process returns to the step of "determining whether the second air pressure is greater than or equal to the first air pressure";

[0079] S630: If the difference is greater than or equal to the second preset value and less than the third preset value, the fan assembly 6 and the valve assembly 9 are controlled to be in a closed state;

[0080] S640: If the difference is greater than or equal to the third preset value, the valve assembly 9 is controlled to be in the open state, and the process returns to the step of “determining whether the second air pressure is greater than or equal to the first air pressure”.

[0081] It can be understood that in the initial state of the double-layer air membrane system, the inflation device of the internal space 3 is continuously inflated, and the first air pressure of the internal space 3 tends to be stable. However, due to the influence of external wind force, internal temperature, etc., the first air pressure of the internal space 3 will fluctuate, thereby affecting the second air pressure of the interlayer unit 5. Therefore, the interlayer unit 5 needs to be pressurized twice or multiple times, and the above steps S6 to S640 are executed each time the pressurization process is completed.

[0082] As mentioned above, after the double-layer air membrane system is formed, the second air pressure is greater than or equal to the first air pressure. For example, during a complete inflation and pressurization process, if the difference between the second air pressure and the first air pressure detected for the first time is less than or equal to the first preset value, it indicates that the air pressure in the interlayer unit 5 is too low to provide support. At this time, the fan assembly 6 needs to be turned on to inflate and pressurize the interlayer unit 5. After the fan assembly 6 is turned on, the process returns to the step of "determining the relationship between the difference and the first preset value, the second preset value, and the third preset value" or the previous step and the cycle continues. If the difference is greater than the first preset value and less than the second preset value for the second time, it indicates that the pressure in the interlayer unit 5 is still insufficient. The fan assembly 6 needs to be kept on and inflation and pressurization continues. The process returns to the step of "determining the relationship between the difference and the first preset value, the second preset value, and the third preset value" or the previous step and the cycle continues. If the difference is greater than or equal to the second preset value and less than the third preset value for the third time, it indicates that the interlayer unit 5 has provided support and the air pressure is sufficient. At this time, the fan assembly 6 needs to be turned off to maintain the pressure, completing the inflation and pressurization process.

[0083] It should be noted that, taking the above-mentioned complete inflation and pressurization process as an example, if the difference detected for the third time is greater than the third preset value, it means that the air pressure of the interlayer unit 5 is over-inflated, and it is necessary to open the valve assembly 9 for appropriate exhaust and pressure relief. The process returns to the step of "determining the relationship between the difference and the first preset value, the second preset value, and the third preset value" or the previous step to loop until the difference is greater than or equal to the second preset value and less than the third preset value. At this time, the fan assembly 6 and the valve assembly 9 are closed to maintain pressure, thus completing the inflation and pressurization process. Controlling the inflation and pressurization timing of the fan assembly 6 and the exhaust and pressure relief timing of the valve assembly 9 effectively avoids the problem of excessive or insufficient inflation and pressurization of the interlayer unit, further improving safety.

[0084] Other permutations and combinations will not be described again here.

[0085] Reference Figure 8 As shown, this embodiment also provides another specific implementation method for controlling the working state of the fan assembly 6 and / or the valve assembly 9 based on air pressure information and temperature information, including but not limited to the following steps:

[0086] S8, determining whether the temperature of the internal space 3 is greater than a preset temperature;

[0087] S810: If the temperature is greater than the preset temperature, the valve assembly 9 is controlled to be in the open state, and the process returns to the step of "determining whether the second air pressure is greater than or equal to the first air pressure";

[0088] S820: If the temperature is less than or equal to the preset temperature, control the valve assembly 9 to be in a closed state.

[0089] It can be understood that during a single inflation and pressurization process, when the temperature of the internal space 3 is too high and requires heat exchange and cooling through ventilation, steps S8 to S820 are executed. When the temperature of the internal space 3 is greater than the preset temperature, indicating that the internal space 3 needs to be cooled, the valve assembly 9 is opened to exhaust and cool the air, and then the process returns to the step of "determining whether the second air pressure is greater than or equal to the first air pressure" or the previous step to cycle. After a certain period of exhaust, the second air pressure of the interlayer unit will decrease. When the cycle detection process detects that the air pressure conditions for opening the fan assembly 6 are met, the fan assembly 6 can automatically open and cooperate with the valve assembly 9 to exhaust and cool the air. When the temperature is detected to be less than or equal to the preset temperature, the valve assembly 9 is closed.

[0090] It should be noted that the fan assembly 6 and valve assembly 9 are independently controlled, and the priority of controlling the valve assembly 9 to be open is higher than the priority of controlling the valve assembly 9 to be closed. This design allows for timely pressure relief and cooling of the sandwich unit 5, preventing over-pressurization of the sandwich unit 5 or excessive internal temperature, thereby improving safety.

[0091] Reference Figure 9 Before executing step S1, the following steps are also included but not limited to:

[0092] S100, determining whether the double-layer air membrane system is in an inflated and pressurized state;

[0093] S110: If the device is in the inflation and pressurization state, execute the subsequent steps;

[0094] S120: If the system is in a non-inflated and pressurized state, the previous step is executed in a loop until the double-layer air membrane system is identified as being in an inflated and pressurized state, and the subsequent steps are executed.

[0095] It is understandable that prioritizing the determination of whether the double-layer air film system requires further inflation and pressurization (e.g., secondary or tertiary inflation) can effectively improve the inflation and pressurization efficiency of the double-layer air film system. The reason is as follows: During initial inflation and pressurization, the double-layer air film system only needs to activate the fan assembly 6 and inflate and pressurize to a predetermined pressure. It does not require the full control method described in the above embodiment. Therefore, determining the applicable scope first can improve efficiency.

[0096] The third aspect of the present application provides a computer-readable storage medium storing a computer program. The computer program is processed to execute the inflation and pressurization control method of the double-layer air membrane system of the above embodiment.
