Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and more specifically, to a modular multi-sensor fusion dynamic leveling construction support device and its usage method. Background Technology

[0002] Existing construction lifting devices and support systems have several shortcomings under complex working conditions, limiting their application effectiveness. Especially in situations requiring precise height and angle control, such as the installation of experimental equipment and floor-to-ceiling windows, existing installation equipment suffers from the following problems: 1. Insufficient pressure monitoring and adjustment capabilities. Existing solutions typically rely on a single pressure sensor or simple load detection, making it difficult to monitor the uniformity of pressure distribution in real time, unable to identify local overloads or stress imbalances, and lacking a dynamic pressure adaptive compensation mechanism. 2. Lack of tilting and attitude adjustment functions. Existing lifting devices only support vertical lifting and cannot achieve platform tilting or local height fine-tuning. Particularly on foundations with uneven hardness, uneven stress can easily cause the platform to tilt, requiring manual intervention for leveling. 3. Weak safety protection and threshold alarm mechanisms. Existing technologies mainly rely on mechanical protection or post-event braking, unable to provide early warning of pressure over-limit risks, and lack intelligent alarm functions with adjustable thresholds. 4. Insufficient modular and collaborative control capabilities. Existing devices are mostly single-unit equipment, making it difficult for multiple units to work collaboratively. They have poor scalability and scenario adaptability, deployment relies on fixed structures, and are difficult to quickly disassemble or flexibly adapt to complex construction environments. 5. Limited dynamic response speed and accuracy. Existing technologies rely on mechanical transmission for adjustment, resulting in high latency and difficulty in coping with sudden load changes. Furthermore, their accuracy depends on a single sensor, failing to integrate data from multiple sensors to eliminate errors. These issues make it difficult for existing technologies to meet the precise support and height adjustment requirements in complex construction environments, particularly in precision installation environments. Summary of the Invention

[0003] The purpose of this application is to provide a modular multi-sensor fusion dynamic leveling construction support device and its usage method, which has the advantages of achieving high-precision dynamic leveling, real-time monitoring of support status, automatic restoration of preset posture, and modular expansion capability.

[0004] This application provides a modular multi-sensor fusion dynamic leveling construction support device, the technical solution of which is as follows: It includes at least one support unit, the support unit comprising: a base for supporting on the installation ground, having a base plate thereon; an air supply assembly disposed within the base for supplying air to an air spring assembly; an air spring assembly comprising a plurality of air springs arranged on the top surface of the base plate, each air spring being connected to the air supply assembly; a pressure-bearing top plate disposed on the top of the air spring assembly and hinged to the air spring assembly via a universal ball joint, for supporting the target body to be installed; and a sensor assembly comprising an tilt sensor assembly disposed on the pressure-bearing top plate to monitor the tilt angle of the pressure-bearing top plate, and a sensor assembly disposed on the base plate... The system includes a displacement sensor assembly on the top surface of the base plate to monitor the lifting height of the pressure plate, and a laser rangefinder assembly on the bottom surface of the base plate to monitor the levelness of the base. A control system, connected to the sensor assembly and the air supply assembly, is configured to control the air intake and exhaust volume of each air spring in the air spring assembly according to control commands, thereby adjusting the height and / or tilt angle of the pressure plate. The control system is also configured to preset the height and / or tilt angle of the pressure plate and receive detection signals from the sensor assembly. Based on the detection signals, when the pressure plate experiences a height or angle change exceeding the preset range, the system automatically adjusts the height of the air spring assembly to restore the pressure plate to the preset height and tilt angle.

[0005] Furthermore, this application also proposes that the air spring assembly includes four air springs arranged in a square shape below the pressure-bearing top plate, and the top of each air spring is hinged to the pressure-bearing top plate through a universal ball joint; the air supply assembly includes an air compressor installed in the base and air storage tanks distributed on both sides of the air compressor, each air storage tank is provided with two sets of air pipes connected to the air springs, and each set of air pipes is provided with a proportional solenoid valve connected to the control system to control the air intake and exhaust volume of the air springs.

[0006] Furthermore, this application also proposes that the gas supply component and the bottom of the base are provided with leveling feet to achieve initial adjustment.

[0007] Furthermore, this application also proposes that a plurality of pressure sensors are arranged on the pressure-bearing top plate, the pressure sensors being distributed at the pressure-bearing top plate corresponding to the air spring position and at the center of the pressure-bearing top plate.

[0008] Furthermore, this application also proposes that the displacement sensor assembly includes four displacement sensors, each disposed on the outside of one of the air springs to monitor the change in the lifting height of the pressure plate above the corresponding position.

[0009] Furthermore, this application also proposes that the base further includes several support feet connecting the base plate, each support foot being provided with a leveling foot for initial height adjustment on the installation ground.

[0010] Furthermore, this application also proposes that it includes a unit data interface, which is connected to the control system and can be connected to multiple support units to form a support device in which multiple sets of support units work together.

[0011] Furthermore, this application proposes that the support unit is configured in several groups, and each group of support units is connected to the control system through a unit data interface, and the control system coordinates the control of multiple groups of support units.

[0012] Furthermore, this application also proposes to form a combined support device of corresponding specifications by splicing different numbers of support units to adapt to different installation requirements.

[0013] Furthermore, this application also proposes a method for using the aforementioned modular multi-sensor fusion dynamic leveling construction support device, comprising the following steps: placing the support unit on the installation plane, and adjusting the leveling feet to initially adjust the levelness of the base based on the detection data from the laser ranging sensor assembly; when multiple support units are combined, connecting the multiple support units to the control system in advance via the unit data interface; placing the target object on the pressure plate of the support unit, and finely adjusting the height and / or tilt angle of the pressure plate using an air spring assembly according to the set height and angle; and the sensor assembly monitoring the height change and tilt angle of the pressure plate in real time. When the height changes, the control system controls the air supply component to synchronously supply or depress air into the air spring assembly to adjust the support unit's return to the preset height in real time. When the tilt angle changes, the control system calculates and controls the air supply component to supply or depress air into part of the air spring assembly to adjust the support unit's return to the preset tilt angle in real time. When the height change or tilt angle change reaches 80% of the first preset threshold, the control system issues a level one alarm and automatically adjusts the air pressure distribution. When the height change or tilt angle change reaches 100% of the first preset threshold, the air spring assembly locks the current air pressure, and the control system issues a level two alarm.

[0014] As can be seen from the above, the modular multi-sensor fusion dynamic leveling construction support device and its usage method provided in this application achieve automatic leveling and attitude maintenance of the construction support device through the coordinated work of multi-sensor fusion monitoring, air spring dynamic leveling and intelligent control system. It has high-precision dynamic leveling, real-time status monitoring, multi-unit collaborative control and safety early warning functions, and effectively solves the problems of low adjustment accuracy, slow response and poor scalability of traditional devices.

[0025] Example 1

[0026] Combination Figures 1 to 9As shown, this embodiment provides a modular multi-sensor fusion dynamic leveling construction support device. The technical solution is as follows: It includes at least one support unit, which includes: a base 1 for supporting on the installation ground, and a base plate 2 thereon; an air supply component, disposed in the base 1, for supplying air to the air spring assembly; an air spring assembly, including a plurality of air springs 11 arranged on the top surface of the base plate 2, each air spring 11 being connected to the air supply component; a pressure-bearing top plate 3, disposed on the top of the air spring assembly and hinged to the air spring assembly via a universal ball joint, for supporting the target body to be installed; and a sensor assembly, including a pressure sensor 15 disposed on the top surface of the pressure-bearing top plate 3 and an tilt sensor assembly disposed on the pressure-bearing top plate 3 to monitor the pressure. The system includes a tilt angle of the top plate 3, a displacement sensor assembly installed on the top surface of the base plate 2 to monitor the lifting height of the pressure-bearing top plate 3, and a laser rangefinder assembly installed on the bottom surface of the base plate 2 to monitor the levelness of the base 1; a control system connected to the sensor assembly and the air supply assembly, configured to control the air intake and air intake of each air spring 11 in the air spring assembly according to control commands to adjust the height and / or tilt angle of the pressure-bearing top plate 3; and the control system is configured to preset the height and / or tilt angle of the pressure-bearing top plate 3, and receive the detection signal from the sensor assembly, so as to automatically adjust the height of the air spring assembly and adjust the pressure-bearing top plate 3 to restore it to the preset height and tilt angle when the pressure-bearing top plate 3 undergoes a height change or angle change that exceeds the preset range according to the detection signal.

[0027] Combination Figures 1 to 6 As shown, in this embodiment, the support unit includes a base plate 2 and a pressure-bearing top plate 3, which are flexibly connected by an air spring assembly. The air supply assembly is connected to the air springs 11 via pipelines, and the sensor assembly includes various detection devices such as pressure, tilt angle, displacement, and laser ranging. After receiving the sensor signals, the control system dynamically levels the pressure-bearing top plate 3 by adjusting the air pressure of each air spring 11.

[0028] The air spring assembly refers to a device that uses compressed air to achieve elastic support, specifically implemented using a rubber airbag structure, with each airbag independently connected to an air supply pipeline. The universal ball joint is a connection mechanism that allows three-dimensional rotation, specifically implemented using a metal joint with a ball-and-socket structure, ensuring effective force transmission when the pressure-bearing top plate 3 tilts. The laser ranging assembly is a non-contact distance measurement device, specifically implemented using a phase-type laser sensor, used to establish a reference horizontal plane. The proportional solenoid valve 9 is a control valve that can precisely adjust the flow rate, specifically implemented using an electromagnetic actuator with position feedback, achieving precise air pressure control. When the pressure-bearing top plate 3 tilts, the tilt sensor 13 detects the angle deviation, and the displacement sensor 12 simultaneously monitors the height changes of each support point. The control system calculates the target air pressure value of each air spring 11 according to preset parameters and achieves air pressure compensation by adjusting the opening of the solenoid valve in the corresponding pipeline. The laser ranging assembly continuously monitors the horizontal state of the base 1, triggering overall height compensation when the foundation settles. The pressure sensor 15 provides real-time feedback on the load distribution; when local overload is detected, the control system automatically increases the spring air pressure in the corresponding area for balance compensation.

[0029] Millisecond-level dynamic compensation of air pressure is achieved through an air spring assembly. Combined with multi-dimensional sensor data fusion, it can simultaneously correct height deviation and angle offset. A three-dimensional attitude monitoring system is constructed through the combined measurement of displacement sensor 12, laser rangefinder, and tilt sensor 13. Furthermore, by setting pressure sensors 15 at key support points, structural failure caused by local overload can be prevented; intelligent dynamic leveling of the construction support device is realized. Multi-sensor collaborative operation can perceive changes in support status in real time, and the air pressure regulation system responds quickly to compensation commands, effectively maintaining the stability of the pressure-bearing platform. When encountering foundation settlement or sudden load changes, the system automatically executes compensation actions, avoiding construction interruptions caused by manual intervention. The modular design supports multi-unit collaborative operation and can flexibly adapt to the needs of construction scenarios of different scales.

[0030] Combination Figures 1 to 6As shown, in this embodiment, the air spring assembly includes four air springs 11 arranged in a square shape below the pressure-bearing top plate 3. The top of each air spring 11 is hinged to the pressure-bearing top plate 3 via a universal ball joint 10. The air supply assembly includes an air compressor 4 installed in the base 1 and air storage tanks 5 distributed on both sides of the air compressor 4. Each air storage tank 5 is provided with two sets of ventilation pipes connected to the air springs 11, and each set of ventilation pipes is provided with a proportional solenoid valve 9 connected to the control system to control the air intake and exhaust volume of the air springs 11. The miniature air compressor 4 is located in the center below the base 1 and is equipped with a silencer cover, enabling dynamic air supply. The air storage tanks 5 are symmetrically arranged on both sides of the air compressor 4, and a safety valve 8 is provided between them. According to the control command, the proportional solenoid valve 9 precisely adjusts the air pressure of each air spring 11; and can realize emergency pressure relief. The air pressure of the air spring 11 can be quickly reduced to a safe value using the solenoid valve. In energy-saving mode, the air supply is switched to the air storage tank 5 during standby, reducing the start-stop frequency of the air compressor.

[0031] The square distribution refers to the four air springs 11 arranged symmetrically in a rectangular pattern at the four corners of the pressure-bearing top plate 3. This can be achieved using a square or rectangular layout, and the symmetrical distribution improves support stability. The universal ball joint 10 is a connection structure that allows the pressure-bearing top plate 3 and the air springs 11 to swing at multiple angles. This can be achieved using a hinge device with a spherical bearing, which compensates for angular deviations (±15°) when the pressure-bearing top plate 3 is tilted. The proportional solenoid valve 9 is a valve that can proportionally adjust the gas flow rate. This can be achieved using a valve core structure driven by an electromagnetic coil, controlling the charging and discharging rate of the air springs 11 by adjusting the valve opening. The silencer is a soundproof structure used to reduce the operating noise of the air compressor. This can be achieved by wrapping the outer shell with sound-absorbing cotton, reducing noise pollution during equipment operation through sound insulation design.

[0032] Specifically, four air springs 11 are arranged in a square, located below the four corners of the pressure-bearing top plate 3. Each air spring 11 is connected to the pressure-bearing top plate 3 via a universal ball joint 10, allowing the pressure-bearing top plate 3 to compensate for angles when tilted. An air compressor 4 and an air tank 5 are integrated inside the base 1. The air tanks 5 are symmetrically distributed on both sides of the air compressor 4, supplying air to two air springs 11 on the same side via two sets of ventilation pipes. The proportional solenoid valve 9 of each ventilation pipe is independently controlled by the control system, adjusting the valve opening to inflate or de-inflate the air springs 11. Each air spring 11 has an inlet 17 and an outlet 18, connected to the ventilation pipes for intake and exhaust, respectively. This arrangement ensures that each air spring 11 has the same travel distance, guaranteeing consistent intake timing and preventing the effects of different intake speeds. The miniature air compressor 4 is located at the center of the bottom of the base 1, encased in a soundproof cover to reduce operating noise. When dynamic air pressure adjustment is required, the control system calculates the target air pressure value based on sensor data and precisely controls the inflation and deflation of each air spring 11 via the proportional solenoid valve 9. In an emergency, the solenoid valve can quickly open to release the internal air pressure of the air spring 11 to a safe threshold. In standby mode, the air supply system switches to the air tank 5 supply mode, reducing the number of start-stop cycles of the air compressor 4 to lower energy consumption.

[0033] Four independently controlled air springs 11, connected by a universal hinge structure, enable the pressure-bearing top plate 3 to compensate for tilt angles. Simultaneously, the coordinated control of the air tank 5 and the proportional solenoid valve 9 achieves rapid pressure response and precise distribution. Furthermore, the combination of the air tank 5 and the energy-saving mode effectively reduces the operating frequency of the air compressor, while the emergency pressure relief function improves system safety under overload conditions. This solution solves the problems of uneven pressure distribution, dynamic adjustment delay, and excessive energy consumption in existing technologies. The symmetrical layout and independent control of the four air springs 11 enable local height fine-tuning of the pressure-bearing top plate 3, ensuring uniform pressure distribution; the cooperation between the proportional solenoid valve 9 and the air tank 5 improves pressure regulation accuracy and response speed; the silencer and energy-saving mode reduce equipment operating noise and energy consumption; and the emergency pressure relief function can quickly reduce air pressure under overload conditions, preventing structural damage.

[0034] Combination Figures 1 to 6As shown, in this embodiment, leveling feet 7 are also provided at the bottom of the air supply component and the base 1 to achieve initial adjustment. Leveling feet 7 refer to adjustable support structures installed at the bottom of the base 1. Specifically, they can be implemented using mechanical anchor bolts with threaded rods, support plates, and locking nuts. The relative height between the support plate and the base 1 is changed by rotating the threaded rod, or electric adjustment can be achieved by setting a motor to control the threaded rod, thereby further improving the level of automation and making the adjustment more precise. This structure allows for manual or electric adjustment of the local height of the base 1 during the initial installation of the device, thereby compensating for uneven ground. Here, the leveling feet 7 are installed at the ends of the four support legs 6 at the bottom of the base 1, each leg equipped with an independent adjustment mechanism. During installation, the operator, based on the ground height data fed back by the laser ranging component, rotates the threaded rod of the leveling feet 7 to make the support plate contact the ground and adjust the overall levelness of the base 1. For example, when there is a local depression in the ground, the leveling feet 7 at the corresponding position can extend the length of the threaded rod to keep the base 1 level. After the initial adjustment is completed, the locking nut is fixed to prevent displacement of the support plate. This process provides a basic horizontal reference for the subsequent automatic leveling of the air spring 11, reducing the initial error of the dynamic adjustment system. It is important to note that when adjusting the leveling feet 7, the levelness or required angle of the base 1 can be adjusted based on real-time monitoring data from the laser rangefinder 14. This solution, through a continuous adjustment mechanism using a threaded rod, can achieve millimeter-level height compensation, shortening installation preparation time and solving the problems of low initial leveling efficiency and insufficient accuracy of the base 1 in existing technologies. The independent adjustment function of the leveling feet 7 allows the device to quickly adapt to complex ground conditions, such as establishing a stable reference plane on slopes exceeding 5°. Simultaneously, this structure reduces the subsequent adjustment amount of the air spring assembly, avoiding frequent air pressure adjustments due to excessive initial errors, thereby extending the service life of the air supply assembly.

[0035] In this embodiment, several pressure sensors 15 are arranged on the pressure-bearing top plate 3. The pressure sensors 15 are distributed above the pressure-bearing top plate 3 corresponding to the installation position of the air spring 11 and at the center of the pressure-bearing top plate 3. Here, the pressure-bearing top plate 3 is made of 1 meter × 1 meter high-strength aluminum alloy plate with a thickness of 20 mm. The surface is anodized and has a load-bearing capacity of not less than 10 tons per square meter.

[0036] The pressure sensors 15 can be implemented using piezoelectric or strain gauge sensors. Multiple sensors are positioned at the connection points of the air springs 11 and the center of the top plate to collect pressure distribution data in real time. The high-strength aluminum alloy plate refers to the load-bearing structural component made of aluminum alloy material, specifically 6061-T6 aluminum alloy sheet. Anodizing treatment improves surface hardness and corrosion resistance, and the 20mm thick sheet design meets high load-bearing requirements. Four pressure sensors 15 are installed on the top surface of the pressure-bearing top plate 3 corresponding to the air springs 11 to monitor load changes at each support point. Another pressure sensor 15 is positioned above the center area of ​​the top plate to detect the overall force balance. The control system generates a pressure distribution heatmap by receiving signals from the five pressure sensors 15 and, combined with data from the tilt sensor 13, dynamically calculates the required air pressure adjustment for each air spring 11. When a local pressure exceeds a preset threshold, the corresponding air spring 11 is immediately triggered for air pressure compensation to prevent structural deformation caused by uneven stress. By installing multiple sets of pressure sensors 15 at key support points and in the central area, a distributed pressure monitoring network is constructed. This network can capture real-time changes in the stress state of various areas of the roof slab, and combined with the control system, achieve dynamic pressure compensation, effectively solving the problem of pressure monitoring blind spots in existing technologies. Real-time monitoring of the pressure distribution across the entire bearing roof slab 3 is achieved, enabling accurate identification of local overloads or stress imbalances. Safety hazards can be promptly eliminated by dynamically adjusting the air pressure of the air springs 11. The combination of multi-point pressure detection and central area monitoring significantly improves the system's adaptability to asymmetric loads, ensuring stable support performance even under complex working conditions.

[0037] The displacement sensor assembly is installed at the four corners of the base plate 2 to monitor the spatial attitude of the pressure-bearing top plate 3 in real time. Specifically, displacement sensors 12 are arranged at the four corners of the top surface of the base plate 2; each displacement sensor 12 is positioned outside one of the air springs 11 to monitor the change in the lifting height of the pressure-bearing top plate 3 above the corresponding position. A three-dimensional spatial coordinate system is constructed using tilt sensor 13, laser rangefinder sensor 14, and displacement sensors 12 to detect the relative displacement between the pressure-bearing top plate 3 and the base 1.

[0038] The displacement sensor 12 is a device that detects the vertical displacement change of the pressure-bearing roof plate 3 through a non-contact measurement method. Specifically, it can be implemented using a laser displacement sensor 12 or a magnetostrictive displacement sensor 12. By being arranged outside the air spring 11, it can independently monitor the real-time height change of each support point. A dual-axis MEMS inclinometer is installed on the bottom surface of the pressure-bearing roof plate 3. The single-point measurement error can be eliminated by using inclinometer sensors 13 at the four corners and the center. The three-dimensional spatial coordinate system refers to the stereo positioning model established by fusing the spatial data of the inclinometer sensor 13, the laser rangefinder sensor 14, and the displacement sensor 12. Specifically, a coordinate transformation algorithm can be used to map the multi-sensor data to a unified coordinate system for accurately calculating the relative displacement relationship between the pressure-bearing roof plate 3 and the base 1.

[0039] In this embodiment, four displacement sensors 12 are symmetrically arranged at the four corners of the top surface of the base plate 2. Each sensor corresponds to the outer position of the air spring 11 and can independently acquire the height change data of the corresponding support point. Dual-axis MEMS inclinometers installed at the four corners and center of the bottom surface of the pressure-bearing top plate 3 form a five-point detection network, which analyzes the spatial tilt angle of the platform in real time through multi-channel data acquisition. The data collected by the laser rangefinder 14, displacement sensors 12, and inclinometer 13 are processed by a coordinate transformation algorithm to generate three-dimensional spatial coordinate parameters containing XY plane displacement and Z-axis height, providing a precise displacement compensation benchmark for the control system. Through multi-sensor spatial layout and data fusion, composite displacement errors caused by foundation settlement or load offset can be eliminated, improving the analytical capability for complex deformations compared to conventional single-point detection methods. This effectively solves the problems of uneven pressure distribution monitoring and insufficient attitude adjustment accuracy in existing technologies. Multi-point displacement detection and three-dimensional coordinate modeling can accurately identify local overload areas, and the dual-axis inclinometer network can capture the spatial tilt state of the platform in real time, providing high-precision feedback data for dynamic leveling, ensuring that the preset support posture can still be maintained under conditions of uneven foundation or sudden load changes.

[0040] This application further proposes that the base 1 also includes several support legs 6 connecting the base plate 2, and each support leg 6 is provided with a leveling foot 7 for initial height adjustment on the installation ground. The support legs 6 are rigid structural components connecting the base plate 2 to the installation ground, and can be implemented using telescopic screws or hydraulic support structures, used to transfer the load of the base 1 to the ground and form stable support.

[0041] During the installation phase, the height of each support leg 6 can be independently adjusted by rotating the threaded structure of the leveling feet 7, ensuring that the base plate 2 reaches a preset horizontal reference. For example, in installation conditions with uneven ground, differentiated height compensation adjustments can be made for different support legs 6 to ensure that the base plate 2 is level overall, providing an initial reference plane for the subsequent dynamic leveling of the air spring assembly. This adjustment process can be completed manually by operating a knob, or automated initial adjustment can be achieved through an electric drive mechanism in conjunction with a level.

[0042] Combination Figures 8 to 9 As shown in this embodiment, each support unit is equipped with a unit data interface 16. The unit data interface 16 is connected to the control system and can connect with multiple support units to form a support device with multiple sets of support units working together. Here, the multiple support units can be distributed separately or assembled in a concentrated manner as needed. Regardless of the method, they can work together through the unit data interface 16.

[0043] Unit data interface 16 refers to a standardized interface used to realize data transmission and communication between multiple support units. Specifically, it can be implemented using RS485, CAN bus, or Ethernet interface. A unified communication protocol is defined to achieve data interaction and command transmission between units. The support device for support unit collaboration refers to a combined support system formed by interconnecting multiple support units through unit data interface 16. Specifically, it can be implemented using a master-slave control architecture or a distributed control architecture to ensure synchronous execution of control commands and real-time sharing of status information among the support units.

[0044] The unit data interface 16 is integrated into the control system, and each support unit's control system is equipped with this interface. When multiple support units need to be combined, each unit connects to the unit data interface 16 via wired or wireless means, allowing sensor data and control commands from multiple support units to be aggregated to the central control system. For example, when supporting a large target, after multiple support units are interconnected through the interface, the central control system can calculate the target air pressure value of each air spring 11 based on the tilt angle, displacement, and pressure data uploaded by each unit and issue adjustment commands to achieve multi-unit coordinated leveling. Furthermore, when the number of support units changes, the unit data interface 16 can automatically identify newly added or removed units and dynamically adjust communication protocol parameters to ensure the real-time performance and reliability of coordinated control. By constructing a multi-unit interconnected system through the unit data interface 16, the load-bearing area and adjustment capability of the support device can be flexibly expanded according to actual needs. For example, when covering a large installation area, existing technologies require customized integral support structures, while this application only requires connecting multiple standard support units through the interface for rapid deployment, significantly improving construction efficiency and scenario adaptability. This solution addresses the shortcomings of existing support systems in terms of modularity and collaborative control capabilities, enabling rapid networking and unified control of multiple support units. For example, when installing ultra-long glass curtain walls, multiple support units, interconnected via interfaces, can synchronously adjust the height and tilt angle of each unit according to the curvature of the curtain wall, ensuring uniform stress distribution and avoiding the risk of deformation due to localized overload. Furthermore, this solution reduces equipment deployment costs in complex construction scenarios, allowing users to flexibly increase or decrease the number of support units according to actual needs without the need to repeatedly purchase specialized equipment.

[0045] For example, in one embodiment, different numbers of support units can be spliced ​​together to form a combined support device of corresponding specifications to adapt to different installation requirements. In the spliced ​​combined support device, the base 1 of each unit is initially leveled by the leveling feet 7, and the control system automatically optimizes the adjustment priority of the air springs 11 of each unit based on the data from the laser ranging component and the tilt sensor 13. Through the modular splicing mechanism, the support device can be expanded or reduced as needed, while maintaining the coordinated leveling function between each unit, which significantly improves deployment flexibility and environmental adaptability.

[0046] Example 2

[0047] This embodiment provides a method for using a modular multi-sensor fusion dynamic leveling construction support device, including the following steps: placing the support unit on the installation plane; adjusting the leveling feet 7 to initially adjust the levelness of the base 1 based on the detection data from the laser rangefinder sensor 14 component; when multiple support units are combined, connecting them to the control system beforehand via the unit data interface 16; placing the target object on the pressure plate of the support unit; and fine-tuning the height and tilt angle of the pressure plate 3 using an air spring assembly according to the set height and angle; and real-time monitoring of the height change and tilt angle of the pressure plate 3 by the sensor assembly. When the height changes, the control system controls the air supply component to synchronously supply or depress air into the air spring assembly to adjust the support unit's return to the preset height in real time. When the tilt angle changes, the control system calculates and controls the air supply component to supply or depress air into part of the air spring assembly to adjust the support unit's return to the preset tilt angle in real time. When the height change or tilt angle change reaches 80% of the first preset threshold, the control system issues a level one alarm and automatically adjusts the air pressure distribution. When the height change or tilt angle change reaches 100% of the first preset threshold, the air spring assembly locks the current air pressure, and the control system issues a level two alarm.

[0048] Furthermore, when multiple laser rangefinders 14, tilt sensors 13, and pressure sensors 15 are monitoring: when laser rangefinders 14 and tilt sensors 13 detect data changes, but the data monitored by displacement sensors 12 remains unchanged, it is determined that the subsidence is caused by local ground collapse. In this case, if the value change detected by laser rangefinders 14 is within the height adjustment range of the air springs, the height can be adjusted using the air springs to restore the predetermined installation angle. If the value change detected by laser rangefinders 14 is outside the height adjustment range of the air springs, the height needs to be adjusted by leveling the feet. When the data detected by laser rangefinders 14 remains unchanged, but the data detected by tilt sensors 13 and displacement sensors 12 changes, it is determined that only the bearing plate has experienced a local height or angle change, and the height of the corresponding air springs is adjusted to restore the angle. Here, the corresponding air springs can be adjusted by one or more air springs. When the data detected by laser rangefinders 14 and tilt sensors 13 remain unchanged, but the data detected by displacement sensors 12 changes, it is determined that the overall height of the bearing plate has changed, and all air springs are controlled to restore the height.

[0049] In this embodiment, the system can generate a pressure distribution heatmap and tilt angle data based on the data from the sensor components, and dynamically calculate the target air pressure value for each air spring 11 through the control system. The opening degree of the solenoid valve is controlled by a PID algorithm. The pressure distribution heatmap refers to the visualization of the pressure distribution map generated by collecting stress data from different areas of the pressure-bearing top plate 3 using pressure sensors 15. Specifically, it can be implemented using a matrix array of pressure sensors 15 combined with data processing algorithms to identify areas of local overload or stress imbalance. The PID algorithm refers to a proportional-integral-derivative control algorithm, which can be implemented through embedded controller programming. It is used to dynamically adjust the opening degree of the solenoid valve based on sensor feedback signals to achieve precise air pressure control.

[0050] After the support unit is placed on the mounting surface, the laser rangefinder 14 first detects the levelness of the base 1, and completes the initial leveling by manually or automatically adjusting the leveling feet 7. When multiple support units are used in combination, the unit data interface 16 connects them to the same control system to form a collaborative working network. After the target body is placed on the pressure-bearing top plate 3, the air springs 11 inflate and deflate according to the preset height and angle to bring the top plate to the initial set position. During operation, the pressure sensor 15 generates a pressure distribution heat map in real time, the tilt sensor 13 monitors the changes in the attitude of the top plate, and the displacement sensor 12 detects the height deviation. The control system integrates the data from multiple sensors and dynamically adjusts the air pressure of each air spring 11 through a PID algorithm. When the height or tilt angle deviates from the preset range, the control system calculates the required air pressure adjustment and controls the proportional solenoid valve 9 to perform the inflation and deflation operation. If the deviation reaches 80% of the first preset threshold, the system triggers a first-level alarm and automatically redistributes the air pressure; if it reaches 100% of the first preset threshold, the air pressure of the control spring assembly is locked and a second-level alarm is triggered to prevent structural damage.

[0051] By integrating data from laser ranging, pressure distribution heatmaps, and tilt sensor 13, and combining this with a PID algorithm to achieve closed-loop control, closed-loop control can be achieved. This automatically identifies and compensates for force imbalances. Simultaneously, multi-unit collaboration is realized through unit data interface 16, significantly improving adjustment accuracy and response speed. This solves the problems of insufficient pressure monitoring and adjustment capabilities, lack of tilting and lifting functions, weak safety alarm mechanisms, and poor collaborative control capabilities in existing technologies. Through dynamic calculation of air pressure distribution and a graded early warning mechanism, precise control of the height and tilt angle of the pressure-bearing roof 3 is achieved, avoiding the risk of local overload. Furthermore, modular design enhances the adaptability and scalability of the construction support device.
