Description

Technical Field

[0001] This invention relates to the field of airships, and in particular to an inflatable aerial platform and a method for launching it. Background Technology

[0002] In recent years, with the widespread application of aerostats in fields such as communication relay, meteorological monitoring, disaster early warning, and border patrol, their structural safety and emergency recovery capabilities have received increasing attention. Especially in complex high-altitude environments, large inflatable aerostats often face sudden localized damage caused by unpredictable factors such as severe airflow disturbances, collisions with external foreign objects, and material aging. Once a leak or damage occurs in any part of the platform structure, it can easily lead to a rapid imbalance in internal gas pressure, resulting in changes in platform attitude, a sudden drop in buoyancy, and even the risk of a catastrophic fall.

[0003] Traditional large airship platforms mostly adopt a single-chamber or a few large-chamber configuration, and their overall buoyancy relies on one or a few air chambers for support. Once a single air chamber leaks, it may cause the entire platform to become unstable. In addition, existing platforms rely heavily on a unified inflation and deflation control system for buoyancy adjustment and attitude control, lacking modular redundancy design, making it difficult to respond promptly and maintain overall balance in the event of partial failure.

[0004] Therefore, how to introduce higher buoyancy redundancy and attitude stabilization mechanisms during the platform structure design stage, and how to quickly restore platform stability when encountering local damage or extreme airflow interference, and avoid a chain reaction disaster of global fall caused by local failure, has become one of the key challenges in the current development of large-scale floating platform technology. Summary of the Invention

[0005] The purpose of this invention is to provide an inflatable aerial platform that has advantages such as high structural safety, good attitude stability, strong resistance to local damage, and high buoyancy control accuracy.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: An inflatable aerial platform, comprising: The main body of the platform has a ring-shaped structure with multiple sets of partitions inside, which divide the interior of the cabin into multiple symmetrically arranged air chambers, and each air chamber has an inflation / deflation port at a corresponding position. Auxiliary balancing chamber: It has a spherical structure. The auxiliary balancing chamber is located at a preset vertical distance from the main platform chamber. The auxiliary balancing chamber is connected to the main platform chamber via a balancing chamber cable. The auxiliary balancing chamber has an inflation / deflation port. The balance control system includes multiple sets of propellers symmetrically arranged on the central horizontal plane of the platform's main cabin, and a rope traction device connected to the platform's main cabin. The propellers and the rope traction device work together to level the attitude of the platform's main cabin.

[0007] Further settings: also include: The payload mounting system includes a pod suspended from the main platform cabin by a pod cable, and the pod has an installation foundation for mounting the mounted equipment; the mounted equipment includes an inflation / deflation device, an attitude sensor, a meteorological monitoring module, a power supply, a wireless communication module, and a network switch; the cable traction device includes at least an optoelectronic composite cable for transmitting power and data signals to the mounted equipment.

[0008] Further settings: The inflation / deflation device is located on the main body of the platform and has multiple devices adapted to each inflation / deflation port; each air chamber is equipped with a pressure sensor. It also includes a control terminal, which is equipped with a multi-channel air pressure regulation module. Based on the external environmental parameters obtained by the meteorological monitoring module and combined with the real-time pressure data of the air pressure sensor, the control terminal dynamically adjusts the internal pressure difference and inflation volume of each air chamber of the main platform cabin to dynamically adapt to environmental changes and maintain the buoyancy of the main platform cabin.

[0009] Further configuration: The propeller is rotatably connected to the main body of the platform, a propeller status sensor is installed, and it has a first direction of horizontal rotation and a second direction of vertical rotation.

[0010] The control terminal can, based on the rope tension data of the traction device and the tilt attitude of the platform main cabin, adjust the thrust vector and rotation direction of the propeller, as well as the traction speed and tension of the traction device, to achieve dynamic leveling of the platform main cabin's attitude, thereby maintaining the attitude of the platform main cabin and rapidly adapting to and compensating for airflow disturbances. The second direction of the propeller is used to provide horizontal thrust, while the first direction is used to adjust the pitch attitude. The control terminal automatically selects the propeller's rotation mode according to changes in the platform's attitude.

[0011] Further configuration: The rope retraction and release device includes: The main cable is connected to the center of the platform's main cabin; the main cable is an optical-electric composite cable. The outer ground anchoring rope is connected to the outer side of the platform's main cabin; The inner ground anchoring rope is connected to the inner side of the platform's main cabin; The winches are multiple, each corresponding to a main cable, an outer ground anchor rope, and an inner ground anchor rope. Each main cable, outer ground anchor rope, and inner ground anchor rope is equipped with a rope tension sensor.

[0012] Further features include: an anchoring vehicle equipped with a cable routing bracket; the winch for the main cable is located on the anchoring vehicle, and the main cable passes through the cable routing bracket.

[0013] Further features include a ground mooring system, which includes anchoring devices for berthing the main platform module and the auxiliary balancing module. The anchoring devices include anchoring supports for the main module and anchoring supports for the balancing module.

[0014] Another object of the present invention is to provide a method for launching an inflatable aerial platform, comprising the following steps: a) Deploy the main platform module on the ground, place it on the main module anchoring support, and inject gas into each air chamber sequentially or simultaneously until each air chamber of the main platform module is uniformly formed and has initial buoyancy. b) Deploy the auxiliary balancing capsule on the ground, place it on the balancing capsule anchor support, connect it to the main platform cabin via the balancing capsule cable, and inflate the auxiliary balancing capsule to provide additional buoyancy and maintain a vertical distance from the main platform cabin. c) Activate the rope traction device to control the winding and unwinding of the main cable, the outer ground anchoring rope and the inner ground anchoring rope, so that the main platform cabin rises from the ground; d) During the ascent of the main platform cabin, adjust the retrieval speed of the traction device and the thrust direction of the propeller to adjust the tilting attitude of the main platform cabin. e) Continuously control the cable retraction and propeller thrust until the main body of the platform reaches the target launch altitude and maintains that altitude.

[0015] Further configuration: The control process in steps c) to e) is implemented by the control terminal, including the following steps: f) During the ascent of the main platform cabin, the control terminal, through the multi-channel air pressure regulation module, dynamically adjusts the internal pressure difference and inflation volume of each air chamber of the main platform cabin based on the external environmental parameters obtained by the meteorological monitoring module and the real-time pressure data of the air pressure sensor, so as to dynamically adapt to environmental changes and maintain the buoyancy state of the main platform cabin. g) The control terminal, based on the rope tension data of the rope traction device, the tilt attitude of the platform main cabin, and the propeller status sensor data, adjusts the thrust vector and rotation direction of the propeller, as well as the retrieval speed and tension of the rope traction device, in order to achieve dynamic leveling of the attitude of the platform main cabin, thereby achieving attitude maintenance of the platform main cabin and rapid adaptive compensation to airflow disturbances. h) After the main body of the platform reaches the target launch altitude, the control terminal continuously monitors the attitude and buoyancy of the main body of the platform and automatically performs fine-tuning control to ensure stable flight of the platform.

[0016] In summary, the present invention has the following beneficial effects: First, in this invention, traditional spherical aerostats are difficult to control in the air, prone to tumbling and twisting; while large inflatable structures face the risk of overall failure when faced with localized damage. This invention, by designing the platform's main cabin as a ring structure and internally incorporating multiple sets of partitions to evenly divide it into symmetrically arranged air chambers, with each chamber having an independent inflation / deflation port, fundamentally changes the failure mode of traditional single-chamber structures. Through physical isolation between the air chambers, even if some chambers leak accidentally, the leakage range can be effectively limited, preventing damage from rapidly spreading to the entire cabin. This significantly reduces the risk of the platform falling due to uneven molding on one side or localized leakage, significantly improving the platform's redundancy safety and fault tolerance. Furthermore, the independent inflation / deflation ports, combined with the ring-shaped multi-partition design, allow for more precise air pressure distribution control during inflation, ensuring uniform molding and maintaining a precise preset geometry. This is crucial for resisting complex wind load disturbances at high altitudes and maintaining optimal aerodynamic shape.

[0017] Secondly, in this invention, by setting up an independent spherical auxiliary balancing chamber and establishing a reasonable vertical distance connection structure between it and the main chamber, a composite distribution of buoyancy is achieved. This layered structure in buoyancy space differs from the single-center buoyancy form of existing floating platforms. When the platform load changes or airflow disturbances occur, the auxiliary chamber can provide more uniform torque support, thereby improving the platform's center of gravity control capability and its ability to restore stability.

[0018] Third, this invention constructs a balance control system by combining a traction device with symmetrically arranged multiple propellers. This system employs a dual-layer attitude adjustment mechanism: coarse adjustment via the traction device and fine adjustment via the propellers. Unlike traditional control methods that rely solely on the tail fin or a single propeller, this system can perform large-angle corrections based on the platform's real-time deflection angle at high altitude through changes in ground cable tension. This, combined with the propeller thrust vector on the platform, achieves fine-tuned attitude leveling, thereby enhancing the platform's adaptive adjustment capabilities to sudden wind disturbances and load offsets. It can respond more flexibly and quickly to sudden airflow changes or load center of gravity shifts, effectively suppressing large-amplitude swaying and enhancing the platform's overall dynamic stability and balance adjustment response speed.

[0019] Fourth, traditional aerial platforms often face challenges in powering high-altitude work equipment and transmitting data: relying on onboard batteries limits endurance; using separate cables and data lines increases system complexity, weight, and aerodynamic drag. This invention highly integrates various onboard devices (including inflation / deflation devices, attitude sensors, weather monitoring modules, power supplies, wireless communication modules, network switches, etc.) within the pod, utilizing a photoelectric composite cable in the traction device as the carrier for power and data transmission. This ensures all onboard equipment receives a continuous and stable power supply, eliminating the need for frequent return trips for charging or battery replacements. Simultaneously, the high-bandwidth data channel provided by the photoelectric composite cable ensures real-time, continuous, and highly reliable transmission of all sensor data back to the ground control system. This is fundamental for platforms requiring precise environmental monitoring, real-time attitude adjustment, and complex task execution, significantly improving mission endurance and data acquisition capabilities.

[0020] Fifth, when large inflatable platforms are in the air, their internal gas state is highly susceptible to changes in external environmental parameters such as temperature and atmospheric pressure, leading to buoyancy loss, chamber deformation, or uneven internal stress. Traditional passive or simple threshold-controlled inflation and deflation methods are ineffective in addressing these issues. This invention addresses this by installing independent pressure sensors in each chamber and configuring a multi-channel pressure regulation module in the control terminal. Combined with external environmental parameters acquired by a meteorological monitoring module, the system dynamically adjusts the air chambers of the main cabin. This elevates the platform's management from simply maintaining air pressure to dynamic, adaptive buoyancy and structural morphology management. By acquiring internal air pressure and external environmental data, the control terminal can anticipate potential buoyancy loss or structural stress caused by sudden drops in temperature or increases in air pressure, and proactively and precisely adjust the inflation volume and internal pressure difference of each chamber to dynamically maintain the optimal buoyancy and structural morphology of the platform's main cabin. This not only ensures the platform's long-term stable loiter capability under various complex weather conditions but also avoids additional aerodynamic drag or structural fatigue caused by chamber deformation, thereby improving the platform's operational efficiency, reliability, and overall lifespan.

[0021] Sixth, traditional airship attitude control relies heavily on single or simple combinations of control methods, making it difficult to effectively cope with complex and ever-changing aerial environmental disturbances. In this invention: First, the propeller is rotatably connected to the platform's main cabin and has a first direction of horizontal rotation and a second direction of vertical rotation. This allows the propeller to provide multi-axial vector thrust, enabling not only vertical lift adjustments but also horizontal thrust to counteract lateral wind loads. Furthermore, precise control of pitch attitude is achieved through vertical adjustment, greatly expanding the flexibility and accuracy of attitude adjustment.

[0022] Secondly, the control terminal, as the core, can perform multi-sensor information fusion based on the rope tension data of the traction device, the tilt attitude of the platform's main cabin, and real-time data from the propeller status sensors. Based on this, the control terminal can intelligently adjust the propeller's thrust vector and rotation direction, as well as the traction speed and tension of the traction device. This collaborative control strategy, combining propellers and ropes and leveraging their complementary advantages, can effectively address the multi-dimensional coupled oscillations and nonlinear aerodynamic disturbances faced by large flexible tethered aerostats in wind fields such as gusts and eddies. Compared to traditional control methods, this system can achieve more precise dynamic leveling and rapid adaptive compensation for airflow disturbances, avoiding control lag or overshoot, thereby significantly improving the platform's attitude maintenance accuracy, anti-disturbance capability, and operational stability in harsh environments.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0027] This invention provides an inflatable aerial platform, such as... Figure 1 As shown, it includes the main platform cabin 100, the auxiliary balance cabin 200, and the balance control system.

[0028] Among them, such as Figure 1 and Figure 2 As shown, the platform's main cabin 100 has an overall annular structure, with multiple sets of partition plates 104 arranged along its circumference. The partition plates 104 evenly divide the internal space of the platform's main cabin 100 into multiple symmetrically arranged air chambers 105 to achieve balanced stress on the structure and stability during inflation. Each air chamber 105 has an independent inflation / deflation port 106 at a corresponding position for the inflation and deflation of gas, facilitating the zoned adjustment of the platform's buoyancy.

[0029] The auxiliary balancing chamber 200 is positioned above the main platform chamber 100, with a predetermined vertical distance between them to form a composite buoyancy structure. The auxiliary balancing chamber 200 has an overall spherical structure and is connected and fixed to the main platform chamber 100 via multiple sets of balancing chamber cables 201. Its body is equipped with inflation / deflation ports 202 for gas injection or release to assist in the stability adjustment of the main platform chamber 100 in the floating state.

[0030] The balance control system includes multiple propellers 110 and a rope traction device. The propellers 110 are symmetrically positioned at the center horizontal plane of the platform main cabin 100, providing multi-directional attitude adjustment thrust during the operation of the platform main cabin 100. The rope traction device is connected to different anchor points of the platform main cabin 100, achieving large-angle attitude leveling of the platform main cabin 100 by adjusting the tension and release of the ropes. The propellers 110 and the rope traction device work together to influence the attitude adjustment process of the platform main cabin 100, responding to airflow disturbances or load shifts during high-altitude operation, and achieving stable hovering and attitude maintenance of the platform main cabin 100.

[0031] like Figure 1 and Figure 3 As shown, the inflatable aerial platform also includes a payload loading system, which includes pods 300 mounted on the main platform cabin 100. The pods 300 are suspended from the inside of the main platform cabin 100 by multiple sets of pod cables 301, thus forming a stable loading structure. The pods 300 have mounting bases 302 inside for equipment installation, used to support various functional modules.

[0032] The gondola 300 can accommodate various mounted equipment 303, including an inflation / deflation device, attitude sensors, a meteorological monitoring module, a power module, a wireless communication module, and a network switch. Each functional module can be flexibly configured according to mission requirements. To ensure continuous power supply and information transmission for the mounted equipment 303, the traction device includes at least one photoelectric composite cable. This cable connects to the platform main cabin 100 and extends into the gondola 300, serving both as one of the load-bearing ropes for the platform main cabin 100 and providing power and data communication channels for the mounted equipment 303, enabling information interconnection and intelligent control of the high-altitude platform.

[0033] In this embodiment, a waterproof structure, such as a canopy or a sealed box structure, can be installed on the pod 300.

[0034] The inflatable aerial platform also includes a control terminal 500, which is electrically connected to the mounting equipment 303 that can be installed in the pod 300, and is used to realize the dynamic adjustment and stable control of the buoyancy state of the main platform cabin 100.

[0035] The inflation / deflation devices are installed inside the pod 300, and their number corresponds one-to-one with the multiple air chambers 105 inside the main platform cabin 100. They are connected to and adapted to the inflation / deflation ports 106 of each air chamber 105. Each air chamber 105 is equipped with a pressure sensor 107 to collect the internal pressure value of the air chamber 105 in real time, so as to reflect the current buoyancy state and gas distribution.

[0036] The control terminal 500 is electrically connected to the meteorological monitoring module, power system, and the aforementioned air pressure sensor 107 mounted on the platform. It contains a multi-channel air pressure regulation module 501. Based on external environmental parameters (including but not limited to wind speed, temperature, and atmospheric pressure) obtained by the meteorological monitoring module, and combined with real-time pressure data collected by the air pressure sensors 107 in each air chamber 105, the control terminal 500 dynamically adjusts the internal pressure difference and inflation volume of each air chamber 105 within the main body cabin 100 of the platform.

[0037] Through the coordinated operation of the above structure and control, the platform can achieve dynamic balance control of buoyancy when facing changes in the high-altitude environment, improve the adaptability of the platform structure in non-ideal environments such as pressure changes and wind disturbances, and ensure that the main body of the platform 100 always maintains a stable floating attitude and safe operation.

[0038] The propellers 110 in the inflatable aerial platform are rotatably connected to the central horizontal plane of the platform's main cabin 100, and are distributed along the symmetrical axis of the platform cabin. Each propeller 110 is equipped with a propeller status sensor for real-time monitoring of the propeller's operating status and rotational speed. The propellers 110 have bidirectional rotation capability, including a first direction of horizontal rotation and a second direction of vertical rotation, which are used to provide attitude adjustment thrust in different directions. The form of rotational connection of the propellers 110 is not limited; in this embodiment, it can be a universal ball joint connection or a hinged connection.

[0039] The inflatable aerial platform further includes a control terminal 500, which establishes communication connections with each propeller 110, propeller status sensors, attitude sensors, and traction devices. The control terminal 500 can comprehensively analyze the platform's current attitude deviation and stress state based on tilt attitude data collected from the attitude sensors of the platform's main cabin 100 and rope tension data obtained from the traction devices. This allows for coordinated control of the thrust vector magnitude, rotation direction, and mode switching of each propeller 110, while simultaneously adjusting the traction speed and tension distribution of the ropes in each traction device, achieving dynamic attitude leveling of the platform during operation. In this embodiment, the control terminal 500 can be a computer displaying data and equipped with a remote control for remote control based on the data displayed on the computer. Alternatively, it can be automatically controlled via a pre-programmed system.

[0040] The propeller 110 outputs horizontal thrust in the second rotation direction to counteract lateral disturbances or yaw, and generates vertical torque in the first rotation direction to adjust pitch attitude. The control terminal 500 can automatically determine and switch the operating modes of each propeller 110 based on the platform's current attitude change trend, forming an adaptive control strategy that actively responds to airflow disturbances, thereby improving the platform's attitude stability and rapid self-recovery capability in complex high-altitude wind fields.

[0041] like Figure 4 As shown, the rope traction device in the inflatable aerial platform is used to achieve attitude constraint and height adjustment of the platform. Its structure includes a main cable 102, an outer ground anchoring rope 101, an inner ground anchoring rope 103, and multiple winches 422.

[0042] The main cable 102 is connected to the bottom center of the platform main cabin 100 and is used to bear the main suspension and vertical traction functions of the platform main cabin 100. The main cable 102 adopts a photoelectric composite cable structure, which has both high mechanical load-bearing capacity and power transmission and data signal transmission functions, providing energy and communication paths for the platform and its mounted equipment 303.

[0043] The outer ground anchor rope 101 is connected to the outer periphery of the platform main cabin 100, and the inner ground anchor rope 103 is connected to the inner ring area of ​​the platform main cabin 100. The two work together to maintain the stability of the platform attitude and adjust the attitude by the difference in tension distribution.

[0044] To ensure independent control of each cable, the platform is equipped with multiple winches 422, which are respectively located at the connection ends of the main cable 102, the outer ground anchoring rope 101, and the inner ground anchoring rope 103. Each winch 422 has an automatic winding and unwinding function. Simultaneously, each cable is equipped with a rope tension sensor to monitor the rope's stress state in real time. Based on this tension data, the control terminal 500 can dynamically adjust the winding and unwinding strategies of the winches 422 to achieve platform attitude leveling, improved wind resistance, and safe mooring control during high-altitude operation.

[0045] like Figure 5 As shown, in this embodiment, each winch 422 is equipped with a counterweight 423. The counterweight 423 can be a water tank.

[0046] In this embodiment, the main cable 102 and the outer ground anchoring cable 101 are retained, while the inner ground anchoring cable 103 can be completely detached to further increase the elevation of the platform main cabin 100 and increase adaptability when necessary.

[0047] like Figure 6As shown, the inflatable aerial platform also includes an anchoring vehicle 420, which is used to provide ground support, winding, and power and communication guidance for the main cable 102.

[0048] Specifically, the anchor vehicle 420 is a movable ground support device, on which a cable routing bracket 421 is installed. The cable routing bracket 421 is used to guide and limit the main cable 102 passing through the anchor vehicle 420, preventing the main cable 102 from getting tangled, bent or accidentally deviating during operation, and ensuring stable and reliable signal and power transmission of the optical fiber composite cable.

[0049] The winch 422 of the main cable 102 is installed on the anchor vehicle 420 to drive the lifting and lowering movement of the main cable 102. Combined with the control strategy of the control terminal 500 for platform height and tension status, it enables precise lifting, hovering, and retrieval of the platform. The coordinated deployment of the anchor vehicle 420, cable support bracket 421, and winch 422 enhances the operational safety and maintenance convenience of the main cable 102, and improves the overall flexibility of the platform's ground support.

[0050] like Figure 7 , Figure 8 and Figure 9 As shown, the inflatable aerial platform also includes a ground tethering system, which is used to ensure stable fixation during docking, positioning, and maintenance operations before and after the platform takes off.

[0051] Specifically, the ground mooring system includes multiple mooring devices, corresponding to the main platform cabin 100 and the auxiliary balancing cabin 200, respectively. The mooring devices include a main cabin mooring support 400 and a balancing cabin mooring support 410. The main cabin mooring support 400 has an arc surface 401, and the balancing cabin mooring support 410 has a spherical surface 411. The main cabin mooring support 400 is positioned on the ground, with multiple supports surrounding the lower periphery of the main platform cabin 100 to reliably moor the main platform cabin 100 to the ground during inflation, maintenance, or static states. The balancing cabin mooring support 410 is correspondingly positioned outside the area formed by the main cabin mooring support 400, providing stable support for the auxiliary balancing cabin 200.

[0052] The aforementioned anchoring supports can be adapted to the platform structure dimensions, and buffer pads or flexible interfaces can be installed in the connection area to prevent damage to the platform structure due to rigid collisions during contact.

[0053] Through the above technical solutions, the platform's main cabin 100 achieves high stability control during takeoff, hovering, and operation. The control terminal 500 receives three-axis tilt information (such as pitch angle, roll angle, and yaw angle) from attitude sensors in real time to obtain the platform's current attitude status. At the same time, it collects tension sensor data from each cable to sense the force distribution in different directions and determine whether there is tilting or swaying caused by wind pressure, off-center load, or uneven cable tension.

[0054] When the platform tilts or experiences uneven stress, the control terminal 500 directly determines the direction and degree of attitude deviation based on tilt angle data and tension changes fed back by sensors. When attitude deviation occurs, the control terminal 500 coordinates the rotation direction and thrust of multiple propellers 110, wherein: The second direction of the propeller 110 is used to correct the platform's yaw or lateral drift, such as in response to disturbances like crosswinds or diagonal ascent. By controlling the propellers 110 on both sides of the symmetrical structure to output different thrusts, a lateral control force is generated, enabling the platform to correct its attitude in the horizontal direction.

[0055] The first direction of the propeller 110 is used to adjust the platform's pitch or roll attitude, such as to cope with forward or backward center of gravity shifts or longitudinal wind shear effects. This mode generates an attitude correction torque in the vertical direction by applying a reverse thrust difference between the front and rear propellers 110.

[0056] Meanwhile, based on the platform offset trend and response delay prediction, the control terminal 500 adjusts the winding and unwinding speed and tension distribution of each cable by the winch 422 while maintaining the stable operation of the propeller 110. For example, it may appropriately increase the winding and unwinding speed of the inner main cable 102 or relax the tension of the anchor rope on one side to help the platform achieve attitude correction and further prevent over-adjustment or sway accumulation.

[0057] This embodiment provides a method for launching an inflatable aerial platform, used to smoothly and safely release the platform from the ground to a predetermined aerial working height while maintaining its attitude stability and buoyancy balance. Before execution, the following site and equipment arrangements are required: I. Preparation and Ground Deployment Phase; Site Layout and Ground Protection: A protective membrane is laid on the ground of the pre-selected launch site to prevent wear and tear on the platform capsule during deployment and inflation. Multiple main cabin mooring supports 400 and balance cabin mooring supports 410 are arranged at predetermined locations within the site, and counterweights 423 are provided for each support to ensure its stability. To facilitate subsequent operations, adjacent mooring supports can be temporarily moved outwards by an appropriate distance.

[0058] Deploying the pods: Deploy the folded platform main cabin 100 and auxiliary balancing cabin 200 onto the ground protective membrane. Move the pod 300 to the center of the platform main cabin 100.

[0059] II. Inflation and System Integration Stage; Inflation and pre-connection of auxiliary balancing chamber 200: Connect the balancing chamber cable 201 of the auxiliary balancing chamber 200 to the winch 422 on the corresponding balancing chamber mooring support 410. Inflate the auxiliary balancing chamber 200 through its inflation / deflation port 202 until it reaches the preset initial buoyancy.

[0060] Platform main body 100 inflation and integration: The platform main body 100 is inflated using an inflation device through the inflation / deflation holes 106 corresponding to each air chamber 105 to ensure uniform molding. During inflation, the following system integration operations are performed simultaneously: Install multiple sets of propellers 110 to their preset positions on the main body of the platform and connect them to control and power cables.

[0061] The main cable 102, which is part of the traction device for launching and retracting the cable, passes under the main body of the platform 100 and connects to the equipment interface inside the pod 300.

[0062] Connect the outer ground anchor rope 101 and the inner ground anchor rope 103 to the corresponding ground winches 422 respectively, and connect the ground end of the main cable 102 to the winch 422 on the anchor vehicle 420.

[0063] After the main platform cabin 100 is inflated to the preset pressure difference, it is precisely moved and placed on the main cabin anchor support 400.

[0064] System connection: The inflated auxiliary balance chamber 200 is connected to the corresponding interface on the main platform chamber 100 via its balance chamber cable 201, and the winch 422 slowly lifts the auxiliary balance chamber 200 to form a preset vertical distance between it and the main platform chamber 100.

[0065] III. Equipment debugging phase before launch; Payload system test: Power on the pod 300 via the optical fiber composite cable, start the control terminal 500, and test the operation of each mounted device in the pod, including sensors for cabin air pressure, altitude, temperature, etc., as well as the automatic inflation and deflation device.

[0066] Balance control system test: Test the main control panel of the rope winding and releasing device, and verify the independent and group control functions of each winch 422, the direction and the accuracy of the rope tension sensor readings.

[0067] IV. Launch and Attitude Control Phase Initial Lifting: The rope traction device is activated, and the control terminal 500 or the central control console coordinates the operation of each winch 422, which are retracted and released in sequence: outer ground anchor rope 101, inner ground anchor rope 103, and main cable 102, so that the platform main cabin 100 rises smoothly and vertically from the main cabin anchor support 400. When the platform rises to the predetermined height, the anchor vehicle 420 drives under the platform.

[0068] If necessary, the platform is raised in stages and its attitude is adjusted: the platform continues to rise. When the height reaches the maximum length of the inner ground anchor rope 103, it is released from the ground winch 422, and the subsequent ascent and attitude control are completed by the outer ground anchor rope 101 and the main cable 102.

[0069] Intelligent collaborative control: The control terminal 500 operates continuously throughout the entire ascent process. Based on external environmental parameters acquired by the meteorological monitoring module and real-time data from the pressure sensor 107, it dynamically adjusts the internal pressure difference of each air chamber 105 through the multi-channel pressure control module 501 to dynamically adapt to environmental changes and maintain stable buoyancy. Based on rope tension data, platform tilt attitude, and propeller status sensor data, it coordinates the thrust vector and rotation direction of multiple propellers 110, and collaboratively controls the release and retraction speed and tension of the rope traction device to achieve dynamic leveling of the platform's attitude and quickly compensate for airflow disturbances.

[0070] For example, when the platform is hovering stably at a certain altitude, if the meteorological monitoring module detects that the ambient temperature drops rapidly from 20°C to 15°C, the control terminal 500 initiates calculations. Based on the principle of thermal expansion and contraction of gases, it determines that this temperature drop will cause the gas in all air chambers 105 to contract, resulting in a loss of approximately 2% buoyancy. To prevent the platform from descending as a result, the control terminal will automatically and evenly replenish a small amount of gas to all air chambers before the platform's actual altitude change occurs, until the data feedback from the internal pressure sensor 107 reaches the preset compensation value, thereby achieving dynamic adaptive compensation for environmental changes.

[0071] V. Platform Reclaim The recovery procedure is initiated by the control terminal 500 or the ground control console. The rope traction device begins to work in concert, and multiple winches 422 release the main cable 102 and the outer ground anchoring rope 101 synchronously at a controlled speed according to a preset control strategy. The attitude is maintained throughout the descent.

[0072] The platform continues to descend until it reaches the preset docking height. At this height, the end of the inner ground anchoring rope 103, which was previously detached during launch, can safely contact the corresponding winch 422 on the ground.

[0073] Reconnecting the cables: The operator reconnects the inner ground anchoring rope 103 to the corresponding winch 422. After the connection is completed, the descent and attitude stabilization of the platform are controlled collaboratively by the main cable 102, the inner ground anchoring rope 103, and the outer ground anchoring rope 101.

[0074] Anchor truck 420 departs: The platform continues to descend to a lower, safer height. At this point, the operator safely drives anchor truck 420, carrying the main cable winch 102, away from the area directly below the platform.

[0075] The control terminal 500 controls the retraction and extension speeds of all winches 422, guiding the main platform cabin 100 slowly towards the main cabin anchor bracket 400 on the ground, ultimately landing smoothly and settling firmly on multiple main cabin anchor brackets 400, completing the retrieval of the main body. After the main platform cabin 100 is secured, the cable below the auxiliary balance cabin 200 is connected to the winch 422 on the balance cabin anchor bracket 410. By tightening the cable, the auxiliary balance cabin 200 is slowly guided and retrieved onto its corresponding balance cabin anchor bracket 410.

[0076] After all the platforms have been safely moored to the ground anchorage, the subsequent dismantling work can be carried out, including: deflating the air chambers 105 of the main platform 100 and the auxiliary balance chamber 200; dismantling components such as the propeller 110 and pod 300 and the onboard equipment; removing all cables; and finally folding and storing the platform capsule.

[0077] The above embodiments are merely explanations of the present invention and are not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
