Description

Technical Field

[0001] The present invention relates to the technical field of construction devices, and in particular to a modular multi-sensor fusion dynamic leveling construction support device and a method for using the device. Background Art

[0002] Existing construction lifting devices and support systems suffer from numerous deficiencies in complex working conditions, limiting their effectiveness. This is particularly true for applications requiring precise height and angle control, such as installing experimental equipment and floor-to-ceiling windows. Existing installation equipment suffers from the following issues: 1. Inadequate pressure monitoring and adjustment capabilities. Existing solutions typically rely on single pressure sensors or simple load detection, making it difficult to monitor pressure distribution uniformity in real time, unable to identify local overloads or force imbalances, and lacking dynamic pressure adaptive compensation mechanisms. 2. Lack of tilting and attitude adjustment capabilities. Existing lifting devices only support vertical lifting and cannot achieve platform tilt or local height fine-tuning. This is especially true on unevenly applied foundations, where uneven force can easily cause the platform to tilt, requiring manual leveling. 3. Weak safety protection and threshold alarm mechanisms. Existing technologies primarily rely on mechanical protection or post-failure braking, providing no early warning of pressure overload risks and lacking intelligent alarm functionality with adjustable thresholds. 4. Inadequate modularity and collaborative control capabilities. Existing devices are mostly standalone devices, making it difficult for multiple units to work together. They also suffer from poor scalability and adaptability to different scenarios. Deployment relies on fixed structures, making them difficult to quickly disassemble and assemble or flexibly adapt to complex construction environments. 5. Limited dynamic response speed and accuracy. Existing technologies rely on mechanical transmission adjustment, resulting in high latency and difficulty responding to sudden load changes. Furthermore, accuracy relies on a single sensor, without integrating multi-sensor data to eliminate errors. These issues make it difficult for existing technologies to meet the precise support and height adjustment requirements in complex construction environments, especially in precision installation environments.

DETAILED DESCRIPTION

[0016] Example 1 Combine Figures 1 to 9As shown, this embodiment provides a modular multi-sensor fusion dynamic leveling construction support device, and the technical solution is as follows: it includes: at least one support unit, the support unit includes: a base 1, which is used to support the installation ground and is provided with a base plate 2; an air supply assembly, which is arranged in the base 1, and is used to supply air to the air spring assembly; the air spring assembly includes a plurality of air springs 11 arranged on the top surface of the base plate 2, and each air spring 11 is connected to the air supply assembly; a pressure top plate 3, which is arranged on the top of the air spring assembly and is hinged to the air spring assembly through a universal ball joint, and is used to support the target body to be installed; a sensor assembly, including a pressure sensor 15 arranged on the top surface of the pressure top plate 3, and an inclination sensor assembly arranged on the pressure top plate 3 to monitor the pressure The inclination angle of the top plate 3, the displacement sensor assembly arranged on the top surface of the base plate 2 to monitor the lifting height of the pressure top plate 3, and the laser ranging assembly arranged on the bottom surface of the base plate 2 to monitor the horizontality of the base 1; a control system connecting the sensor assembly and the air supply assembly, which is configured to control the air intake and air collection volume of each air spring 11 in the air spring assembly according to the control instructions to adjust the height and / or inclination angle of the pressure top plate 3; and the control system is configured to preset the height and / or inclination angle of the pressure top plate 3, and receive the detection signal of the sensor assembly, so as to automatically adjust the height of the air spring assembly and then adjust the pressure top plate 3 to restore to the preset height and inclination angle according to the detection signal when the pressure top plate 3 changes in height or angle beyond the preset range.

[0017] Combine Figures 1 to 6 As shown, in this embodiment, the support unit comprises a base plate 2 and a pressure-bearing top plate 3, with an air spring assembly between them providing a flexible connection. The air supply assembly is connected to the air springs 11 via pipelines, and the sensor assembly includes various detection devices, including pressure, inclination, displacement, and laser ranging. After receiving sensor signals, the control system dynamically adjusts the air pressure in each air spring 11 to achieve leveling of the pressure-bearing top plate 3.

[0018] The air spring assembly is a device that uses compressed air to achieve elastic support. Specifically, it can be implemented using a rubber airbag structure, with each airbag independently connected to an air supply line. A universal ball joint is a connection mechanism that allows three-dimensional rotation. Specifically, it can be 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-shifted laser sensor, used to establish a reference horizontal plane. The proportional solenoid valve 9 is a control valve that precisely adjusts flow. Specifically, it can be implemented using an electromagnetic actuator with position feedback, enabling precise control of air pressure. When the pressure-bearing top plate 3 tilts, the inclination sensor 13 detects angular deviation, and the displacement sensor 12 simultaneously monitors the height change of each support point. The control system calculates the target air pressure for each air spring 11 based on 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 horizontality of the base 1 and triggers overall height compensation when the foundation settles. The pressure sensor 15 provides real-time feedback on load distribution. When a local overload is detected, the control system automatically increases the spring pressure in the corresponding area to compensate for the balance.

[0019] Millisecond-level dynamic compensation of air pressure is achieved through air spring assemblies, and combined with multi-dimensional sensor data fusion, height deviation and angular offset can be corrected simultaneously. Through the combined measurement of displacement sensor 12, laser ranging and inclination sensor 13, a three-dimensional posture monitoring system is constructed, and 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 achieved. Multiple sensors work together to sense changes in support status in real time, and the air pressure regulation system quickly responds to compensation instructions to effectively maintain the stability of the pressure platform. When encountering foundation settlement or sudden load changes, the system automatically performs compensation actions to avoid construction interruptions caused by manual intervention. The modular design supports multi-unit collaborative operations and can flexibly adapt to the needs of construction scenarios of different scales.

[0020] Combine 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 located within a base 1 and air tanks 5 located on either side of the air compressor 4. Each air tank 5 is equipped with two sets of ventilation pipes connected to the air springs 11. Each set of ventilation pipes is equipped with a proportional solenoid valve 9 connected to the control system to control the air intake and output of the air springs 11. The micro air compressor 4 is located in the center below the base 1 and is equipped with a silencer to enable dynamic air supply. The air tanks 5 are symmetrically located on either side of the air compressor 4, with a safety valve 8 located between them. The proportional solenoid valves 9 precisely adjust the air pressure of each air spring 11 according to control instructions and can also provide emergency pressure relief. The solenoid valves can quickly reduce the air pressure in the air springs 11 to a safe level. In energy-saving mode, the air supply switches to the air tanks 5 during standby, reducing the frequency of air compressor startup and shutdown.

[0021] Among them, the square distribution means that the four air springs 11 are arranged in the four corner areas of the pressure top plate 3 in a rectangular symmetrical form. Specifically, it can be achieved by a square or rectangular layout, and the support stability is improved by symmetrical distribution. The universal ball joint 10 refers to a connection structure that allows the pressure top plate 3 and the air spring 11 to swing at multiple angles. Specifically, it can be achieved by a hinged device with a spherical bearing. The hinged structure compensates for the angular deviation (±15°) when the pressure top plate 3 is tilted. The proportional solenoid valve 9 refers to a valve that can proportionally adjust the gas flow. Specifically, it can be achieved by a valve core structure driven by an electromagnetic coil. The inflation and deflation rate of the air spring 11 is controlled by adjusting the valve opening. The silencer refers to a sound insulation structure used to reduce the operating noise of the air compressor. Specifically, it can be achieved by wrapping the outer shell with sound-absorbing cotton. The sound insulation design reduces noise pollution during equipment operation.

[0022] Specifically, four air springs 11 are arranged in a square pattern, 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 for angular compensation when the pressure-bearing top plate 3 tilts. An air compressor 4 and an air reservoir 5 are integrated within the base 1. The air reservoirs 5 are symmetrically located on either side of the air compressor 4, supplying air to the two air springs 11 on the same side through two sets of ventilation pipes. The proportional solenoid valve 9 in each ventilation pipe is independently controlled by the control system, adjusting the valve opening to inflate or deflate the air springs 11. The air springs 11 are provided with an air inlet 17 and an air outlet 18, each connected to the ventilation pipe for intake and collection, respectively. This arrangement ensures that each air spring 11 has the same airflow path, ensuring consistent air intake timing and preventing the effects of varying intake velocities. The miniature air compressor 4 is located at the bottom center of the base 1 and is enclosed in a soundproofing hood to reduce operating noise. When dynamic air pressure adjustment is required, the control system calculates the target pressure based on sensor data and precisely controls the inflation and deflation of each air spring 11 via 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 air storage tank 5, reducing the number of starts and stops of the air compressor 4 and thus reducing energy consumption.

[0023] Through four independently controlled air springs 11 and a universal hinge structure, the pressure top plate 3 can be compensated for the tilt angle, and at the same time, the coordinated control of the air tank 5 and the proportional solenoid valve 9 is utilized to achieve rapid response and precise distribution of air pressure. In addition, 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 the safety of the system under overload conditions. This solution solves the problems of uneven pressure distribution, dynamic adjustment delay and excessive energy consumption in the existing technology. The symmetrical layout and independent control of the four air springs 11 realize the local height fine-tuning of the pressure top plate 3 to ensure uniform pressure distribution; the cooperation of the proportional solenoid valve 9 and the air tank 5 improves the air pressure regulation accuracy and response speed; the silencer and energy-saving mode reduce the equipment operation noise and energy consumption; the emergency pressure relief function can quickly reduce the air pressure in the event of overload to avoid structural damage.

[0024] Combine Figures 1 to 6As shown, in this embodiment, leveling feet 7 are installed between the air supply assembly and the base 1 to facilitate initial adjustment. Leveling feet 7 are adjustable support structures installed at the base 1. Specifically, they can be implemented using mechanical anchor bolts with a threaded rod, a support plate, and a locking nut. The relative height between the support plate and the base 1 can be adjusted by rotating the threaded rod. Alternatively, a motor can be used to control the threaded rod for electronic adjustment, further enhancing automation and providing more precise adjustment. This structure allows for manual or electronic adjustment of the base 1's local height during initial installation to compensate for ground unevenness. Here, the leveling feet 7 are installed at the ends of four support legs 6 at the base 1, each equipped with an independent adjustment mechanism. During installation, the operator rotates the threaded rod of the leveling feet 7 based on ground height data fed back by the laser ranging assembly to bring the support plate into contact with the ground and adjust the overall level of the base 1. For example, if there is a local depression in the ground, the leveling feet 7 at the corresponding location can extend the length of the threaded rod to maintain the base 1 level. After the initial adjustment is completed, the locking nut is secured to prevent the support plate from moving. 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 should be noted that when adjusting the leveling foot 7, the horizontality or required angle of the base 1 can be adjusted according to the real-time monitoring data of the laser ranging sensor 14. The present solution can complete the height compensation with millimeter-level accuracy through the continuous adjustment mechanism of the threaded rod, shortening the installation preparation time and solving the problem of low efficiency and insufficient accuracy of the initial leveling of the base 1 in the prior art. The independent adjustment function of the leveling foot 7 enables the device to quickly adapt to complex ground conditions. For example, a stable reference plane can still be established on a slope with an inclination of more than 5°. At the same time, this structure reduces the subsequent adjustment amount of the air spring assembly, avoids frequent air pressure adjustments due to excessive initial errors, and thus extends the service life of the air supply assembly.

[0025] 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. The pressure-bearing top plate 3 is made of a 1 meter x 1 meter high-strength aluminum alloy plate with a thickness of 20 mm and an anodized surface. The load-bearing capacity is not less than 10 tons per square meter.

[0026] The pressure sensor 15 can be implemented using a piezoelectric or strain gauge sensor. By arranging multiple points at the connection points of the air spring 11 and the center of the top plate, it can collect pressure distribution data in real time. High-strength aluminum alloy plates refer to load-bearing structural components made of aluminum alloy materials. Specifically, 6061-T6 aluminum alloy plates can be used. Anodizing can improve surface hardness and corrosion resistance. The 20 mm thick plate design can meet high load-bearing requirements. Four pressure sensors 15 are installed on the top surface of the pressure-bearing top plate 3 at the positions corresponding to the air springs 11 to monitor load changes at each support point. Another pressure sensor 15 is arranged above the center area of the top plate to detect the overall force balance. The control system generates a pressure distribution heat map by receiving signals from the five pressure sensors 15. Combined with the data from the inclination sensor 13, it dynamically calculates the air pressure value required to adjust each air spring 11. When it is detected that the local pressure exceeds the preset threshold, the air spring 11 in the corresponding area can be immediately triggered to perform pressure compensation to prevent structural deformation caused by uneven force. 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 changes in the stress state of each area of the roof in real time. Combined with the control system, dynamic pressure compensation is implemented, effectively resolving the blind spot issue in pressure monitoring in existing technologies. This network enables real-time monitoring of the pressure distribution across the entire pressure-bearing roof 3, accurately identifying local overloads or stress imbalances and promptly eliminating safety hazards by dynamically adjusting the air pressure in 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 operating conditions.

[0027] The displacement sensor assembly is installed at the four corners of the base plate 2 to monitor the spatial posture of the pressure-bearing top plate 3 in real time. Specifically, displacement sensors 12 are placed 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 height changes of the pressure-bearing top plate 3 above the corresponding position. A three-dimensional spatial coordinate system is constructed using the inclination sensor 13, the laser ranging sensor 14, and the displacement sensors 12 to detect the relative displacement of the pressure-bearing top plate 3 and the base 1.

[0028] Among them, the displacement sensor 12 refers to a device that detects the vertical displacement change of the pressure top plate 3 by non-contact measurement. Specifically, it can be implemented by using a laser displacement sensor 12 or a magnetostrictive displacement sensor 12. By being arranged on the outside of the air spring 11, the real-time height change of each support point can be independently monitored. A dual-axis MEMS inclinometer is provided on the bottom surface of the pressure top plate 3. The multi-point layout of the inclination sensors 13 at the four corners and the center can eliminate the single-point measurement error. The three-dimensional spatial coordinate system refers to a stereo positioning model established by the fusion of spatial data of the inclination sensor 13, the laser ranging sensor 14 and the displacement sensor 12. Specifically, a coordinate transformation algorithm can be used to map the multi-sensor data into a unified coordinate system for accurately calculating the relative displacement relationship between the pressure top plate 3 and the base 1.

[0029] In this embodiment, four displacement sensors 12 are symmetrically arranged in 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 obtain the height change data of the corresponding support point. The dual-axis MEMS inclinometers installed at the four corners and the 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 ranging sensor 14, the displacement sensor 12, and the inclination sensor 13 are processed by the coordinate conversion algorithm to generate three-dimensional spatial coordinate parameters including XY plane displacement and Z-axis height, providing an accurate displacement compensation reference for the control system. Through the spatial layout of multiple sensors and data fusion, the compound displacement error caused by foundation settlement or load offset can be eliminated, and the analysis capability of complex deformation is improved compared with the conventional single-point detection method. It effectively solves the problems of uneven pressure distribution monitoring and insufficient posture adjustment accuracy in the existing technology. Multi-point displacement detection and three-dimensional coordinate modeling can accurately identify local overload areas. 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 be maintained under conditions of uneven soft and hard foundations or sudden load changes.

[0030] This application further proposes that the base 1 also includes a plurality of support legs 6 connected to the base plate 2. Each support leg 6 is provided with a leveling foot 7 for preliminary height adjustment on the installation surface. The support legs 6 are rigid structural components connecting the base plate 2 to the installation surface. Specifically, they can be implemented using retractable screws or hydraulic struts, and are used to transfer the load of the base 1 to the ground and provide stable support.

[0031] During installation, the height of each support leg 6 is independently adjusted by rotating the threaded structure of the leveling foot 7, bringing the base plate 2 to a predetermined horizontal reference. For example, on unevenly soft and hard installation surfaces, differentiated height compensation adjustments can be made for each support leg 6 to ensure the overall levelness of the base plate 2, providing an initial reference plane for subsequent dynamic leveling of the air spring assembly. This adjustment process can be performed manually with a manual knob, or automatically using an electric drive mechanism in conjunction with a spirit level.

[0032] Combine Figures 8 and 9 As shown, in this embodiment, each support unit is provided with a unit data interface 16, which is connected to the control system and can be connected to multiple support units to form a support device with multiple groups of support units working together. Here, the multiple support units can be distributed in a dispersed manner or assembled in a centralized manner as needed. Regardless of the method, the coordination is achieved through the unit data interface 16.

[0033] The unit data interface 16 is a standardized interface for data transmission and communication between multiple support units. Specifically, this can be implemented using RS485, CAN bus, or Ethernet interfaces. By defining a unified communication protocol, data exchange and command transmission between units are achieved. A collaborative support device is a modular support system formed by interconnecting multiple support units via the unit data interface 16. Specifically, this can be implemented using a master-slave control architecture or a distributed control architecture, ensuring synchronized execution of control commands and real-time sharing of status information from each support unit.

[0034] The unit data interface 16 is integrated into the control system, and the control system of each support unit is equipped with this interface. When multiple support units need to be combined, each unit is connected to the unit data interface 16 via wired or wireless means, so that the sensor data and control instructions of multiple support units can be aggregated into the central control system. For example, when carrying a large target object, after multiple support units are interconnected through the interface, the central control system can uniformly calculate the target air pressure value of each air spring 11 based on the inclination, displacement, and pressure data uploaded by each unit and issue adjustment instructions to achieve multi-unit collaborative leveling. Furthermore, when the number of support units changes, the unit data interface 16 can automatically identify the newly added or removed units and dynamically adjust the communication protocol parameters to ensure the real-time and reliability of the collaborative control. By building a multi-unit interconnected system through the unit data interface 16, the load-bearing area and adjustment capacity of the support device can be flexibly expanded according to actual needs. For example, when it is necessary to cover a large installation area, the existing technology requires a customized integral support structure, while the present 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 issues of insufficient modularity and collaborative control capabilities of existing support devices, enabling rapid networking and unified control of multiple support units. For example, when installing an extra-long glass curtain wall, multiple support units can be interconnected via interfaces, allowing the height and inclination of each unit to be adjusted synchronously based on the curvature of the curtain wall, ensuring even force distribution and avoiding the risk of deformation due to local overload. Furthermore, this solution reduces equipment deployment costs in complex construction scenarios, allowing users to flexibly increase or decrease the number of support units based on actual needs without the need to repeatedly purchase specialized equipment.

[0035] For example, in one embodiment, different numbers of support units can be spliced together to form a modular support device of corresponding specifications to accommodate different installation requirements. In the assembled modular support device, each unit base 1 undergoes preliminary leveling calibration using leveling feet 7. The control system automatically optimizes the adjustment priority of each unit's air spring 11 based on data from the laser ranging component and inclination sensor 13. This modular splicing mechanism allows the support device to be expanded or reduced as needed while maintaining the coordinated leveling function between the units, significantly improving deployment flexibility and environmental adaptability.

[0036] Example 2 The present embodiment provides a method for using a 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 7 to preliminarily adjust the horizontality of the base 1 according to the detection data of the laser range sensor 14 component; when multiple support unit combinations are provided, the multiple support units are preliminarily connected to the control system through the unit data interface 16; placing the target on the pressure plate of the support unit, and using the air spring component to fine-tune the height and tilt angle of the pressure top plate 3 according to the set height and angle; the sensor component monitors the height change and tilt angle of the pressure top plate 3 in real time. Changes; when the height changes, the control system controls the air supply assembly to synchronously supply or collect air into the air spring assembly to adjust the support unit to a preset height in real time; when the tilt angle changes, the control system controls the air supply assembly to supply or collect air into part of the air spring assembly through calculation to adjust the support unit to a preset tilt angle in real time; when the height change or the tilt angle change reaches 80% of the first preset threshold, the control system issues a first-level alarm and automatically adjusts the air pressure distribution; when the height change or the 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 second-level alarm.

[0037] Furthermore, when the multiple laser ranging sensors 14, tilt sensors 13, and pressure sensors 15 perform monitoring: when the laser ranging sensors 14 and tilt sensors 13 detect data changes, while the monitoring data of the displacement sensor 12 does not change, it is determined that the cause is local ground collapse. At this time, if the value change detected by the laser ranging sensor 14 is within the height adjustment range of the air spring, the air spring can be used to adjust the height to restore the predetermined installation angle. If the value change detected by the laser ranging sensor 14 is outside the height adjustment range of the air spring, the height needs to be adjusted using the leveling feet. When the data detected by the laser ranging sensor 14 does not change, while the tilt sensors 13 and displacement sensors 12 detect data changes, it is determined that only the local height or angle change of the pressure-bearing top plate has occurred. The height change is restored by adjusting the height of the corresponding air springs. The corresponding air springs here can be adjusted by a single air spring or multiple air springs. When the data detected by the laser ranging sensor 14 and tilt sensor 13 does not change, but the data of the displacement sensor 12 changes, it is determined that the entire height of the pressure-bearing top plate has changed, and all air springs are controlled to restore the height.

[0038] In this embodiment, the system can generate a pressure distribution thermodynamic map and inclination data based on the data from the sensor assembly, dynamically calculate the target air pressure value of each air spring 11 through the control system, and control the solenoid valve opening through the PID algorithm. The pressure distribution thermodynamic map refers to the force data of different areas of the pressure-bearing top plate 3 collected by the pressure sensor 15 and the generation of a visual pressure distribution map. Specifically, this can be achieved by using a matrix array of pressure sensors 15 combined with a data processing algorithm to identify local overload or force imbalance areas. The PID algorithm refers to a proportional-integral-differential control algorithm, which can be implemented specifically through embedded controller programming. It is used to dynamically adjust the solenoid valve opening according to the sensor feedback signal to achieve precise air pressure control.

[0039] After the support unit is placed on the mounting surface, the laser rangefinder 14 first checks the horizontality of the base 1, and preliminary leveling is achieved through manual or automatic adjustment of the leveling feet 7. When multiple support units are used in combination, the unit data interface 16 connects them to the same control system, forming a collaborative working network. After the target object is placed on the pressure-bearing top plate 3, the air springs 11 are inflated and deflated according to the preset height and angle, bringing the top plate to the initial set position. During operation, the pressure sensor 15 generates a real-time pressure distribution thermogram, the inclination sensor 13 monitors changes in the top plate's posture, and the displacement sensor 12 detects height deviation. The control system integrates the multi-sensor data and dynamically adjusts the air pressure of each air spring 11 using a PID algorithm. When the height or inclination angle is detected to deviate 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 operations. If the deviation reaches 80% of the first preset threshold, the system triggers a level 1 alarm and automatically redistributes the air pressure. If it reaches 100% of the first preset threshold, the air pressure in the control spring assembly is locked and a level 2 alarm is triggered to prevent structural damage.

[0040] By integrating laser ranging, pressure distribution thermal map and tilt sensor 13 data, combined with PID algorithm to achieve closed-loop control, it can automatically identify and compensate for force imbalance, and realize multi-unit coordination through unit data interface 16, which significantly improves the adjustment accuracy and response speed. It solves the problems of insufficient pressure monitoring and adjustment capabilities, lack of tilt lifting function, weak safety alarm mechanism and poor collaborative control capabilities in the prior art. Through dynamic calculation of air pressure distribution and graded early warning mechanism, precise control of the height and tilt angle of the pressure top plate 3 is achieved, avoiding the risk of local overload, and improving the scene adaptability and scalability of the construction support device through modular design. It should be understood that: the above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. All technical solutions under the concept of the present invention belong to the protection scope of the present invention.
