[0002] Air-ribbed membrane structures are composed of multiple gas-filled columns assembled together. Once inflated, these columns maintain a certain shape and rigidity, serving as part of the supporting structure. Due to their flexibility and mobility, they are widely used in large stadiums, exhibition halls, temporary warehouses, and other fields. Their modular design facilitates transportation and allows for rapid assembly and disassembly.
[0003] Air-ribbed membrane structures consist of multiple air columns, and changes in their internal pressure difference directly affect the stability and safety of the air-supported membrane structure. Currently, commonly used air supply and control methods have the following problems:

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0024] like Figure 1-3 As shown: Example
[0025] The intelligent control system 1 is based on a PLC control system and includes sensors for wind speed, temperature, and humidity. The PLC collects data from these sensors and controls the start / stop of fan A2, the opening / closing of branch main electric valves 1 / 2 / 3, and the opening / closing of the electric pressure relief valve according to logic to maintain the air-finned membrane structure within its normal operating pressure range. Fan A2 uses a variable frequency soft start to ensure smooth operation. The system employs an HMI (Human-Machine Interface) for easy monitoring of system operation status by on-site personnel (e.g., ...). Figure 3 ).
[0026] Gas supply device ( Figure 2(It) includes a fan A2 for supplying gas, the air inlet of the fan A2 is connected to a filter A1, the air outlet of the fan A2 is connected to the inlet end of a check valve A3, the outlet end of the check valve A3 is connected to a main air bag A5 for gas collection and shunt through a connection port A4, a pressure relief electric valve A6 is provided on the main air bag A5, the air outlet of the main air bag A5 is connected to a branch main pipe electric valve, one end of a branch main pipe electric valve A8 is connected to one end of a three-way joint A9, a pressure measuring pipe lock A10 is connected to the middle position of the three-way joint A9, the pressure measuring pipe lock A10 is connected to a pressure sensor A11, and the other end of the three-way joint A9 is connected to the interface 1 of a branch main pipe 4 through a first pipeline 11.
[0027] A number of branch main pipe air outlets are provided on the branch main pipe 4, the branch main pipe air outlet 6 is connected to the air inlet of an air column 2 through an air column 2 hose, adjacent air columns 2 are connected to different branch main pipes, a total of 3 branch main pipes are provided in the air film structure, and the air columns 2 that connect the branch main pipe two 7 / 3 to both ends of the same branch main pipe 4 as an air wall are connected to different branch main pipes.
[0028] This distributed gas supply connection can control the opening / closing of the branch main pipe electric valve through an intelligent control system 1 to self-check which part has problems, can automatically cut off the impact of the problematic part on the overall structure, and can also more effectively and accurately analyze the fault point to facilitate the customer to handle it in time.
[0029] The distributed modular gas supply connection ensures that the damage of the branch main pipe or the air column 2 will not have a great impact on the entire membrane structure, ensures the stability of the structure, and also meets the requirements of product standardization design.
[0030] The pressure sensor is connected to the input side of the PLC of the intelligent control system 1 through a signal line.
[0031] The pressure measuring pipe 9 is laid on the top of the branch main pipe in a downward drooping shape through an air pipe lock, a three-way joint and a first pipeline, and the drooping position is < 1 / 5 of the height of the main pipe, so as to avoid the internal water vapor of the main pipe from entering the inside of the pressure measuring pipe 9 and causing the pressure signal to fail. This measure can protect the pressure measuring pipe 9, prevent the pressure measuring pipe 9 from falling off, and ensure the accuracy of the monitoring signal of the intelligent control system 1.
[0032] Logic function (air replenishment):
[0033] The branch main pipe electric valves A8 / 2 / 3 are normally open, the P1 / P2 / P3 pressure difference range is normal, and when P1 / P2 / P3 < the lower pressure limit --> the fan A2 starts to replenish air at the average pressure; <000008
[0036] Three activations or P1 / P2 / P3 <pressure limit---> frequent alarm activation---> main airbag A5 / branch main pipe / air column 2 leak:
[0037] Self-check and analyze for leaks:
[0038] ②-①, close the electric valve 2 / 3, and analyze the pressure changes of P1 / P2 / P3:
[0039] a. P1 value varies greatly, while the P2 / P3 pressure values are within the normal pressure differential.
[0040] If branch main A has a minor air leak, then fan A2 will frequently start to replenish air; if there is a major air leak (fan A2 replenishing air < lower limit), then electric valve 1 will be shut off; the same applies to P2 / P3.
[0041] b. P1 / P2 / P3 pressure values show no significant change and are within the normal range ----> Main airbag A5 leaks; P1 / P2 / P3 < lower pressure limit, fan A2 starts, electric valves 1 / 2 / 3 open, pressure > upper pressure, electric...
[0042] When valves 1 / 2 / 3 are closed, fan A2 stops.
[0043] Electric valves 1 / 2 / 3 are normally open; the differential pressure range of P1 / P2 / P3 is abnormal.
[0044] ① If the pressure difference range of P2 / P3 is normal, and P1>P2 / P3---->electric valve 1 is abnormal or pressure measuring tube 91 is abnormal;
[0045] ②The pressure difference between P2 and P3 is within the normal range, P1 <p2 p3---->Manometer 9A abnormal / Leakage in the main branch pipe A
[0046] ---> Fan A2 starts to supply air for compensation,
[0047] At a certain time, the lower pressure limit < P1 < the upper pressure limit ---> Fan A2 stops ---> Leakage in the main branch pipe 1 - 4 / Air column 2 in the branch
[0048] P1 continues to drop for a certain time ---> Leakage in the main branch pipe 1 - 4 ---> Electric valves 2 / 3 close ---> Fan A2 continuously supplies air for compensation (during the compensation process, the pressure values of P2 / P3 < (lower limit + a certain value), and the electric valves 2 / 3 open for air compensation)
[0049] The same applies to P2 / P3;
[0050] Logic function (exhaust):
[0051] ① The pressure differences of P1 / P2 / P3 are normal,
[0052] At a certain time, the pressure > exhaust pressure ---> Relief valve failure -- Emergency handling of the failure
[0053] ② The pressure differences of P1 / P2 / P3 are abnormal,
[0054] Assume P1 > exhaust pressure, P2 / P3 are within the normal range, P1 manometer abnormal / Electric valve failure, exhaust according to the pressure values of P2 / P3, electric valve failure - Manually pull out the quick - connect joint for exhaust;
[0055] The same applies to P2 / P3.
[0056] In the present utility model, unless otherwise clearly specified and defined, for example, it can be fixedly connected, detachably connected, or integrated; it can be mechanically connected or electrically connected; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0057] The above is the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
