Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of large outdoor tents, and in particular to a form control method, device, equipment and medium for a large outdoor tent. BACKGROUND

[0002] In the prior art, in order to balance the convenience of construction and structural strength, the main structure of a large outdoor tent is usually composed of a metal support frame and a tent cloth, and is assembled by connecting members such as bolts, pins and clamps. After the large outdoor tent is constructed, when the large outdoor tent is used for a long time in an outdoor environment, its structure is inevitably significantly affected by the ambient temperature.

[0003] Specifically, the air pressure of the inflatable cloth top of the large outdoor tent increases with the increase of temperature and decreases with the decrease of temperature. When the air pressure of the inflatable cloth top increases with the increase of temperature, the form of the inflatable cloth top expands. Conversely, when the air pressure of the inflatable cloth top decreases with the decrease of temperature, the form of the inflatable cloth top shrinks, which easily causes the main structure of the large outdoor tent to lose stability and thus lose most of its carrying capacity.

[0004] The above-mentioned form change of the inflatable cloth top caused by temperature change not only reduces the reliability of the large outdoor tent after assembly, but also fundamentally weakens the structural stability and long-term safety margin of the tent, which has significant hidden dangers. SUMMARY

[0005] Therefore, the present application aims to provide a form control method for a large outdoor tent, which can adjust the running posture of the inflatable cloth top by pressurizing and depressurizing the inflatable cloth top according to different temperature values when the inflatable cloth top is irradiated by sunlight, so as to improve the structural stability of the large outdoor tent.

[0061] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0062] Reference Figure 9 , Figure 10 and Figure 11The large outdoor tent house comprises a control module 100, a collection module 200, an air pressure adjusting module 300, a support frame module 400 and an inflatable cloth top 500. The inflatable cloth top 500 is covered on the upper part of the site by the support frame module 400. The control module 100 is connected with the collection module 200 and the air pressure adjusting module 300 respectively. The air pressure adjusting module 300 is connected with the support frame module 400. The inflatable cloth top 500 is connected with the air pressure adjusting module 300.

[0063] It should be noted that the inflatable cloth top 500 is supported and fixed by the support frame module 400 and is wholly covered on the upper space of the target site to form the main enclosure structure of the large outdoor tent house. The collection module 200 is used to obtain the temperature data of the large outdoor tent house and the air pressure data of the inflatable cloth top 500. The air pressure adjusting is used to adjust the air pressure of the inflatable cloth top 500 to assist the support frame module 400 to maintain the structural stability of the large outdoor tent house.

[0064] Further, when the inflatable cloth top 500 is directly irradiated by sunlight or is in a high-temperature environment, the internal air pressure of the inflatable cloth top 500 is increased to cause the inflatable cloth top 500 to appear thermal expansion deformation. When the inflatable cloth top 500 is in a low-temperature environment, the internal air pressure of the inflatable cloth top 500 is reduced to cause the inflatable cloth top 500 to appear cold contraction. Therefore, in this embodiment, when the internal temperature of the large outdoor tent house is high, the air pressure of the inflatable cloth top 500 is reduced by the air pressure adjusting module 300 to reduce the lateral pressure of the inflatable cloth top 500 on the support frame. At the same time, the temperature is partially blocked by the inflatable cloth top 500 to offset the strength decrease of the support frame module 400 caused by high temperature.

[0065] When the internal temperature of the large outdoor tent house is low, the air pressure of the inflatable cloth top 500 is increased to keep the inflatable cloth top 500 in a certain expansion to assist the inflatable cloth top 500 to be supported and to disperse the local stress of the support frame module 400 to avoid the load of the support frame module 400 to be too concentrated. The dynamic balance of the temperature, the air pressure and the supporting force of the large outdoor tent house is achieved to avoid the structural fatigue caused by long-term extreme temperature, thereby significantly improving the safety performance and the service life of the large outdoor tent house.

[0066] The support frame module 400 comprises a plurality of support columns 410 and a plurality of pipes 420. The support columns 410 and the inflatable cloth top 500 are connected by the pipes 420. The air pressure adjusting module 300 comprises an air pipe 310, a switch unit 320 and a pressure adjusting unit 330. The air pipe 310 is connected with the inflatable cloth top 500 by the pipes 420. The switch unit 320 and the pressure adjusting unit 330 are connected with the control module 100. The pressure adjusting unit 330 comprises a wind valve 331, a ball valve 332, a differential pressure transmitter 333 and a pressure switch 334. The pressure switch 334 is connected with the differential pressure transmitter 333. The differential pressure transmitter 333 is connected with the wind valve 331 and the ball valve 332 respectively.

[0067] It should be noted that the pipeline 420 is used to accurately transmit the gas output by the gas pressure regulating unit to the inflatable cloth top 500, or to discharge the excess gas in the inflatable cloth top 500 through the pipeline 420, so as to realize the regulation of the internal gas pressure of the inflatable cloth top 500. In addition, the pipeline 420 is arranged in dependence on the support column 410, which can effectively enhance the connection stability between the support columns 410, reduce the shaking of a single support column 410 caused by lateral force (such as wind force or thrust of the inflatable cloth top 500), and thus improve the overall anti-deformation capability of the support frame module 400.

[0068] The switch unit 320 is used to receive pressure regulation instructions, and quickly open or close the gas pressure passage. When it is necessary to regulate the gas pressure of the inflatable cloth top 500, the switch unit 320 is opened, so that the gas can enter the inflatable cloth top 500. When the gas pressure of the inflatable cloth top 500 reaches the target value, the switch unit 320 is closed, so as to prevent abnormal change of the gas pressure of the inflatable cloth top 500.

[0069] The differential pressure transmitter 333 is used to detect the difference between the internal gas pressure of the inflatable cloth top 500 and the external environment gas pressure in real time, and convert the differential pressure data into an electrical signal and transmit it to the control module 100. The control module 100 determines whether the current gas pressure of the inflatable cloth top 500 meets the target value (for example, the target differential pressure is 800 Pa, and if the actual detection is 300 Pa, it means that the gas pressure is insufficient) according to the data, so as to provide data basis for subsequent regulation. At the same time, the change of the gas pressure in the gas pipe 310 can be detected, so as to indirectly judge whether the gas pressure transmission is normal (for example, blockage of the gas pipe 310 will cause abnormal differential pressure).

[0070] The acquisition module 200 includes a pressure acquisition unit, a first temperature acquisition unit and a second temperature acquisition unit. The pressure acquisition unit, the first temperature acquisition unit and the second temperature acquisition unit are connected with the control module 100. The pressure acquisition unit is arranged in the inflatable cloth top 500. The first temperature acquisition unit is arranged outside the large outdoor tent. The second temperature acquisition unit is arranged inside the large outdoor tent. The large outdoor tent is further provided with a temperature regulation module, which is connected with the control module 100.

[0071] It should be noted that the pressure acquisition unit is arranged in a wrinkle-free part of the inflatable cloth top 500, so as to avoid the influence of air flow disturbance on accuracy. The pressure acquisition unit is used to acquire the gas pressure value in the inflatable cloth top 500 in real time. The first temperature acquisition unit is arranged outside the large outdoor tent, and is used to acquire the real-time temperature value of the environment in which the tent is located. The second temperature acquisition unit is arranged inside the large outdoor tent, and is used to acquire the temperature value of the internal space of the large outdoor tent in real time.

[0072] Referring to Figure 1 , Figure 1For the overall flowchart of the form control method of the large outdoor tent, the form control method of the large outdoor tent includes but is not limited to the following steps:

[0073] Step S11, the acquisition module acquires the real-time temperature value of the environment where the large outdoor tent is located and a plurality of second real-time temperature values of the inflatable cloth top at different illumination angles;

[0074] It should be noted that the temperature state of the large outdoor tent is directly affected by the seasonal climate conditions of the region due to long-term exposure to the outdoor open environment: on the one hand, the replacement of seasons in different regions will bring significant differences in light intensity (such as strong light direct in summer and weak light radiation in winter), and the difference in absorption of light energy directly leads to rapid fluctuations in the temperature of the tent surface and the interior; on the other hand, the seasonal change of environmental temperature (such as the daytime temperature can reach above 35℃ in high temperature season, and the nighttime temperature can drop to below -10℃ in low temperature season), further aggravating the dynamic adjustment of the overall temperature of the tent. The above two factors superimposed make it difficult for the real-time temperature value of the large outdoor tent to remain stable, showing dynamic changes with regional seasons, day and night periods. The continuous fluctuation of temperature will directly act on the support frame module and the inflatable cloth top of the tent. Therefore, the acquisition module of the present embodiment acquires the real-time temperature value of the environment where the large outdoor tent is located and a plurality of second real-time temperature values of the inflatable cloth top at different illumination angles.

[0075] Step S12, confirming the inflation state of the inflatable cloth top according to the first real-time temperature value and the second real-time temperature value;

[0076] Step S13, obtaining the current air pressure value of the inflatable cloth top, and generating a pressure adjustment signal when the current air pressure value is not in the preset first pressure interval;

[0077] Step S14, the air pressure adjustment module responds to the pressure adjustment signal to control the air pressure adjustment module to perform pressure relief operation and pressure increasing operation on the inflatable cloth top to adjust the form of the inflatable cloth top;

[0078] Step S15, when the form of the inflatable cloth top is adjusted to the preset form, the form adaptive control of the inflatable cloth top is completed.

[0079] It should be noted that in the actual operation of the large outdoor tent, the form change of the inflatable cloth top will directly act on the support frame module, and when the first real-time temperature value and the second real-time temperature value increase or decrease the air pressure of the inflatable cloth top, it will cause the support frame module and the inflatable cloth top to deform. In order to effectively avoid the deformation problem of the inflatable cloth top, the acquisition module of the present embodiment continuously monitors the first real-time temperature value of the environment where the large outdoor tent is located and a plurality of second real-time temperature values of the inflatable cloth top at different illumination angles, and generates a corresponding pressure adjustment signal based on the current air pressure value of the inflatable cloth top:

[0080] When the air-supported fabric canopy is in the inflated state, a pressure adjustment signal is generated. The air pressure adjustment module performs a pressure relief operation on the air-supported fabric canopy according to the pressure adjustment signal. The pressure relief can reduce the lateral pressure of the air-supported fabric canopy on the support frame, provide space for the expansion of the support frame, and avoid deformation of the connecting device caused by excessive extrusion stress.

[0081] When the air-supported fabric canopy module is in the deflated state, a pressure adjustment signal is generated. The air pressure adjustment module performs a pressure increase operation on the air-supported fabric canopy according to the pressure adjustment signal. The pressure increase can keep the air-supported fabric canopy fully inflated, assist in supporting the air-supported fabric canopy, and disperse the local stress of the support frame module, avoiding loosening of the structure of the support frame module.

[0082] At the same time, the attitude adjustment of the air-supported fabric canopy can indirectly buffer the internal temperature of the large outdoor tent (such as increasing the tension when the air-supported fabric canopy is inflated, reducing the internal temperature caused by direct sunlight; and retaining a certain air layer when the air-supported fabric canopy is moderately deflated, reducing heat loss in a low-temperature environment), assisting in maintaining the stability of the ambient temperature of the support frame module, and reducing the repeated effects of temperature fluctuations on the connecting device; and the air-supported fabric canopy can form uniform support on the air-supported fabric canopy through adaptive air pressure adjustment, avoiding insufficient local support caused by problems of the connecting device, and ultimately significantly improving the structural safety and reliability of the large outdoor tent in long-term outdoor use.

[0083] It should be noted that the direct sunlight can increase the temperature in the air-supported fabric canopy, thereby increasing the current air pressure value of the air-supported fabric canopy in different areas. In the present embodiment, multiple air-supported fabric canopies are provided, and the air pressure adjustment module controls the air pressure adjustment of different air-supported fabric canopies, thereby adjusting the operating attitude of the air-supported fabric canopy. By adjusting the air pressure of different air-supported fabric canopies, the air pressure of the air-supported fabric canopy is ultimately balanced, so that the air-supported fabric canopy assists in supporting the support frame module, further improving the safety of the large outdoor tent, and reducing the effect of temperature on the support frame module.

[0084] In addition, in an embodiment, referring to Figure 2 , in Figure 1 the step S14 of the embodiment shown, the pressure relief operation and the pressure increase operation of the air-supported fabric canopy by the control air pressure adjustment module further includes the following steps:

[0085] Step S21, when the current air pressure value is lower than the lower limit value of the first pressure interval, a pressure increase instruction is generated, and when the current air pressure value is higher than the upper limit value of the first pressure interval, a pressure decrease instruction is generated;

[0086] Step S22, control the switch unit to be turned on to establish an air pressure path from the air-supported fabric canopy through the pipeline, the switch unit to the pressure adjustment unit;

[0087] Step S23, the pressure regulating unit responds to the pressure increasing instruction and the pressure decreasing instruction to perform a pressurization operation or a pressure relief operation on the inflatable cloth top through the air pressure passage until the current air pressure value is in the first pressure interval.

[0088] It should be noted that the current air pressure value in the inflatable cloth top is obtained in real time by the acquisition module, and the control module compares and judges in combination with the preset first pressure interval, which can timely identify whether the internal pressure of the inflatable cloth top deviates from the safe and effective range, thereby ensuring the timeliness of the pressure regulation of the inflatable cloth top, effectively avoiding safety risks such as rupture and excessive expansion of the inflatable cloth top due to excessively high pressure, and problems such as functional failure of the inflatable cloth top due to excessively low pressure, and significantly improving the safety and reliability of the large outdoor tent.

[0089] Further, the switch unit is selectively opened to establish the air pressure passage in the embodiment, and the connection between the inflatable cloth top and the pressure regulating unit is only conducted when adjustment is needed, which can reduce invalid energy consumption and air pressure interference in a non-adjustment state. At the same time, the pressure regulating unit performs pressurization or pressure relief operation according to the pressure increasing instruction and the pressure decreasing instruction until the pressure of the inflatable cloth top returns to the first pressure interval. This mechanism can effectively avoid the problems of overshoot or insufficient regulation caused by fixed amount regulation, improve the accuracy and efficiency of the internal pressure control of the inflatable cloth top, and ensure that the inflatable cloth top is always in a pressure state that meets the functional requirements.

[0090] In addition, in an embodiment, referring to Figure 3 In Figure 2 In step S24 of the embodiment shown, the pressurization operation or the pressure relief operation on the inflatable cloth top through the air pressure passage further includes the following steps:

[0091] Step S31, the differential pressure transmitter monitors the first pressure value and the second pressure value at both ends of the air pressure passage in real time, and generates a differential pressure signal according to the first pressure value and the second pressure value;

[0092] Step S32, the pressure switch generates a first valve body control instruction of the air valve and a second valve body control instruction of the ball valve according to the differential pressure signal;

[0093] Step S33, according to the first valve body control instruction and the second valve body control instruction, the air valve and the ball valve are driven to regulate the air pressure of the inflatable cloth top to control the operating state of the inflatable cloth top.

[0094] It should be noted that one end of the air pressure passage communicates with the inside of the inflatable tent top, and the other end communicates with the outside of the inflatable tent top. This structure determines that there is an air pressure difference between the two ends of the air pressure passage when the inflatable tent top is in an inflated state. Based on this, the first pressure value (inside the inflatable tent top) and the second pressure value (outside the inflatable tent top) of the air pressure passage are collected in real time by the differential pressure transmitter, and a differential pressure signal is generated according to the two values, which is used as the core basis for judging whether the pressure of the inflatable tent top is abnormal, and provides data support for subsequent accurate adjustment of the pressure of the inflatable tent top.

[0095] Further, for the execution link of pressure regulation, the system adopts a cooperative control mode: after the air valve is started in response to the first valve body control instruction, it can actively supplement gas to the inside of the inflatable tent top, thereby quickly completing the pressurization operation of the inflatable tent top; the ball valve is started in response to the second valve body control instruction, and the opening degree of the ball valve is controlled to realize the directional discharge of the gas in the inflatable tent top. Through the cooperation of the pressurization and pressure relief actions of the air valve and the ball valve, the pressure of the inflatable tent top can be flexibly adjusted, and the deployment, maintenance or folding of the inflatable tent top can be accurately controlled, so that the inflatable tent top always meets the use requirements.

[0096] In addition, in an embodiment, referring to Figure 4 , in Figure 3 , the step S33 of the embodiment shown comprises the following steps:

[0097] Step S41, acquiring the real-time pressure value of the inflatable tent top;

[0098] Step S42, when the real-time pressure value is lower than the preset first pressure interval, starting the air valve to perform a pressurization operation on the inflatable tent top according to the first valve body control instruction, so that air is injected into the inflatable tent top, and the inflatable tent top is kept inflated;

[0099] Step S43, when the real-time pressure value is higher than the first pressure interval, starting the ball valve to perform a pressure relief operation on the inflatable tent top according to the second valve body control instruction, to discharge the excess air in the inflatable tent top, so that the inflatable tent top runs stably.

[0100] It should be noted that the real-time pressure value of the inflatable tent top is acquired by the acquisition module, and the first pressure interval of the inflatable tent top is preset according to the use scene of the large outdoor tent. For example, when the large outdoor tent is in autumn and the diurnal temperature difference is 10-15℃, the first pressure interval is set to 0.3-0.5MPa, and when the real-time pressure value of the inflatable tent top is lower than 0.3MPa, intervention is needed.

[0101] It should be noted that the air valve is connected with an external air source (such as an air compressor), and the ball valve is installed at the exhaust port of the inflatable roof. When the real-time pressure value is lower than the lower limit value of the first pressure interval, the control module generates a pressure adjustment instruction, and the pressure adjustment unit generates a first valve body control instruction and drives the air valve to open, so that the external gas enters the inflatable roof through the pipeline, performs a pressurization operation, and gradually increases the pressure in the inflatable roof. When the real-time pressure value is higher than the upper limit value of the first pressure interval, the control module generates a pressure adjustment instruction, and the pressure adjustment unit generates a second valve body control instruction and drives the ball valve to open, so that the gas in the inflatable roof is discharged through the exhaust port, performs a pressure relief operation, and gradually reduces the pressure in the inflatable roof. When the real-time pressure value is within the first pressure interval, no action is performed, and the system continues to monitor the pressure of the inflatable roof.

[0102] In addition, in an embodiment, with reference to Figure 5 , in Figure 1 In step S14 of the embodiment shown, the air pressure adjustment module, in response to the pressure adjustment signal, further includes the following steps:

[0103] In step S51, the pressure acquisition unit synchronously acquires the internal air pressure data of the inflatable roof at a first preset period;

[0104] In step S52, the first temperature acquisition unit synchronously acquires the first real-time temperature value at a second preset period, and the second temperature acquisition unit synchronously acquires the internal temperature value at a third preset period;

[0105] In step S53, the control module compares the air pressure data with the preset average air pressure range of the inflatable roof, and when the air pressure data is within the average air pressure range, generates a pressure adjustment signal according to the state of the support frame module;

[0106] In step S54, the difference between the first real-time temperature value and the internal temperature value is calculated, and the difference is compared with the preset second temperature interval, and when the difference is within the second temperature interval, a pressure adjustment signal is generated according to the state of the support frame module.

[0107] It should be noted that in an outdoor environment, wind, human activity, snow and other factors can easily cause the air pressure of the inflatable roof to fluctuate. For example, strong winds can compress the local inflatable roof, causing the internal air pressure to rise sharply; the area where people concentrate and stay may cause the air pressure of the inflatable roof to drop due to increased load.

[0108] In this embodiment, the pressure acquisition unit synchronously acquires the internal air pressure data of the inflatable roof at a first preset period, ensuring that the above-mentioned air pressure changes are captured in time. The control module compares the acquired real-time air pressure data with the preset average air pressure range, and generates a corresponding adjustment signal in combination with the current state of the support frame module:

[0109] When the real-time air pressure data is higher than the upper limit of the average air pressure range, or the support frame module is in a thermal expansion state, a pressure adjustment signal is generated to reduce the air pressure of the air-supported roof by a pressure relief (deflation) operation to avoid the air pressure being too high to cause the air-supported roof to burst or the support structure to deform.

[0110] When the real-time air pressure data is lower than the lower limit of the average air pressure range, or the support frame module is in a cold contraction state, a pressure adjustment signal is generated to increase the air pressure of the air-supported roof by a pressure increase (inflation) operation to ensure that the air-supported roof maintains sufficient support force to prevent the tent form from collapsing or wrinkling.

[0111] The first temperature acquisition unit synchronously acquires the real-time temperature of the environment in which the large outdoor tent is located at a second preset period, and the second temperature acquisition unit synchronously acquires the internal temperature value inside the large outdoor tent at a third preset period. The control module calculates the difference between the two types of temperatures to determine the influence of temperature change on the air pressure of the air-supported roof. For example, when exposed to high temperature, the internal temperature of the tent is much higher than the real-time temperature of the environment due to heat accumulation, causing the gas in the air-supported roof to expand and the air pressure to rise. In a low-temperature environment, the internal gas contracts, and the internal temperature may be lower than the real-time temperature of the environment, causing the air pressure of the air-supported roof to drop.

[0112] When the difference between the two types of temperatures is in a preset second temperature interval (i.e., the temperature difference has a significant impact on the air pressure in the air-supported roof), the control module generates a pressure adjustment signal in combination with the state of the support frame module to perform targeted operations on the air-supported roof.

[0113] When the difference between the two types of temperatures is in a preset second temperature interval (i.e., the temperature difference has a significant impact on the air pressure of the air-supported roof), the control module generates a pressure adjustment signal in combination with the state of the support frame module to perform targeted operations on the air-supported roof.

[0114] If the temperature difference causes the air pressure of the air-supported roof to be too high (e.g., high-temperature gas expansion), or space needs to be released for the thermal expansion of the support frame, a first adjustment signal is generated to avoid structural risks by pressure relief.

[0115] If the temperature difference causes the air pressure of the air-supported roof to be too low (e.g., low-temperature gas contraction), or additional support is needed for the cold contraction of the support frame, a second adjustment signal is generated to maintain the support force by increasing the pressure.

[0116] When the air pressure fluctuation caused by the temperature difference is complex, two types of adjustment signals can be generated simultaneously to ensure that the air pressure of the air-supported roof is stable within a safe range through fine pressure increase and pressure relief.

[0117] In addition, in an embodiment, with reference to Figure 6 In Figure 1 the step S11 of the embodiment shown, after the acquisition module acquires the real-time temperature value of the environment in which the large outdoor tent is located, the following steps are further included:

[0118] In step S61, the control module acquires seasonal information and light intensity information of the region where the large outdoor tent is located, and generates a plurality of third temperature intervals according to the seasonal information and the light intensity information;

[0119] In step S62, when the internal temperature value is not in the preset third temperature interval, the control module generates a third adjustment signal;

[0120] In step S63, the temperature adjustment module responds to the third adjustment signal to adjust the internal temperature value until the internal temperature value is in the second temperature interval.

[0121] It should be noted that the seasonal change (such as high temperature in summer and severe cold in winter) of the region where the large outdoor tent is located and the light intensity fluctuation (such as midday sun and cloudy weak light) will directly cause the internal temperature of the tent to change differently. The internal temperature may rapidly rise to above 40℃ under strong light in summer, and the internal temperature may decrease to below 0℃ under weak light in winter. If a fixed temperature interval is used for adjustment, problems such as adjustment lag or excessive adjustment may occur. The control module acquires the seasonal information and the light intensity information to generate a plurality of third temperature intervals adapted to different scenes (for example, the third temperature interval is set to 25-30℃ under strong light in summer, the third temperature interval is set to 15-20℃ under weak light in winter, and the third temperature interval is set to 20-25℃ on cloudy days in spring and autumn), and realizes dynamic adaptation of temperature adjustment. Without manual switching of the temperature threshold, the temperature adjustment adjusts the internal temperature value according to the third adjustment signal, automatically matches the optimal interval according to the real-time season and light, avoids the internal heat caused by the fixed interval being too high in summer or the internal cold caused by the fixed interval being too low in winter, and greatly improves the comfort of personnel activities in the tent.

[0122] By way of example, the air conditioning module in the embodiment includes but is not limited to an air conditioner, a heating device, a refrigeration device, and the like, as long as it can adjust the internal temperature of the large outdoor tent, and the embodiment is not specifically limited.

[0123] In addition, in an embodiment, with reference to Figure 7 In Figure 1 In step S12 of the embodiment shown, the inflation state of the inflatable tent top is determined according to the first real-time temperature value and the second real-time temperature value, and the following steps are further included:

[0124] In step S71, when the first real-time temperature value is lower than the second real-time temperature value, and the current air pressure value shows an upward trend, it is determined that the inflatable tent top is in an inflation state;

[0125] In step S72, when the first real-time temperature value is lower than the second real-time temperature value, and the current air pressure value shows a downward trend, it is determined that the inflatable tent top is in a deflation state;

[0126] Step S73: When the first real-time temperature value and the second real-time temperature value are within the preset temperature range and the current air pressure value remains stable, it is determined that the inflatable cloth top is in a stable state.

[0127] Step S74: Obtain the steady-state pressure value of the inflatable fabric top when it is in a stable state, and query the calibrated pressure-volume relationship data based on the steady-state pressure value and the second real-time temperature value to confirm the expansion state of the inflatable fabric top.

[0128] It should be noted that the air pressure changes of the inflatable roof may originate from its own active inflation / deflation adjustments, or be passively affected by the thermal expansion and contraction of the ambient temperature. By introducing a comparison between a first real-time temperature value and a second real-time temperature value, the precondition for the temperature difference is defined: the air pressure trend is only linked to the shape state when the first real-time temperature is lower than the second real-time temperature. This eliminates interference from passive air pressure increases caused by temperature rises and passive air pressure decreases caused by temperature drops, ensuring a strong correlation between air pressure changes and the active expansion / contraction of the inflatable roof, thus improving the accuracy of state recognition.

[0129] A stable state is determined and the steady-state pressure value of the inflatable tent is collected only when the first and second real-time temperature values ​​are within preset ranges and the air pressure inside the inflatable tent is stable, thus avoiding data distortion caused by air pressure fluctuations. During the expansion and contraction phases of the inflatable tent, real-time monitoring of temperature and air pressure trends quickly identifies abnormal states (such as excessive inflation or tent leakage if the temperature is below the preset range but the air pressure continues to rise; or a sudden drop in air pressure if the temperature is normal, which may indicate tent damage). Alarms are triggered promptly, or adaptive adjustments are made (such as stopping inflation or initiating pressurization), preventing safety accidents such as tent collapse due to excessive expansion or contraction. Using the first and second real-time temperature values ​​as prerequisites for steady-state determination adapts to dynamic changes in outdoor temperature, ensuring that benchmark data is collected only when the ambient temperature is relatively stable, thus improving the reliability of determinations in complex temperature environments.

[0130] Furthermore, this embodiment, through strong air pressure trend and steady-state detailed judgment, not only takes into account the real-time dynamic adjustment of the inflatable roof shape, but also ensures the stability of the steady-state operation of the inflatable roof, so that the inflatable roof shape adaptive system can cope with the variability of the outdoor environment and avoid judgment failure or adjustment misoperation caused by environmental interference.
