[0002] Under the policy guidance of green and low-carbon transformation and industrial upgrading in the construction industry, prefabricated buildings, with their core advantages such as standardized production, prefabricated construction, controllable construction period, and low resource consumption, have become an important direction for the high-quality development of the construction industry. Their construction process covers multiple core links, including prefabricated component production, transportation, stacking, hoisting, and installation. The technical control effect of each link directly affects the overall structural safety, functionality, and construction benefits of the project. Among these, the transportation and hoisting of prefabricated components, as a key link between prefabricated component production and on-site installation, directly determines the construction quality and progress speed of prefabricated buildings through its operational efficiency, accuracy, and safety. Currently, this link still faces many technical bottlenecks and management loopholes, seriously restricting the large-scale and high-quality development of the prefabricated building industry.

[0003] For example, the utility model patent with authorization announcement number CN222007009U discloses a lifting device for precast concrete components of assembled buildings. This solution includes longitudinal beams, transverse beams, upper lifting lugs, and movable lifting lugs. Two longitudinal beams and two transverse beams are provided.

Four upper lifting lugs are provided, each fixedly connected to one of the four corners of the upper surface of the "#" structure. Each transverse beam has at least two movable lifting lugs that can be adjusted and fixed in position on the transverse beam. This utility model has strong applicability, a wide lifting range, low safety risk, convenient installation, simple operation, and easy disassembly. It can be reused, saving costs. This utility model can be spliced ​​in two or more parts, solving problems such as limited lifting range, low lifting efficiency, and high safety risk, effectively reducing damage to precast components during transportation, secondary transfer, and lifting. The utility model patent with authorization announcement number CN216863365U discloses a prefabricated component hoisting equipment that is convenient for transportation and unloading and has high hoisting accuracy. It includes an installation frame, movable blocks, an anti-slip mechanism, and a steel wire connecting rope. The installation frame is connected to a crane via an auxiliary connecting rope. The installation frame includes two horizontal bars and two vertical bars. Four movable blocks are fitted around the outside of each of the two horizontal bars.

[0004] The aforementioned patent provides a hoisting device for prefabricated components of prefabricated buildings. However, in practice, the weight of prefabricated components is often uneven on both sides. During hoisting, the weight imbalance can easily lead to the failure of the prefabricated components to be hoisted. The existing hoisting devices cannot monitor the status of the prefabricated components during the hoisting process, nor can they adjust the device when problems are detected during the hoisting of the prefabricated components. This is not conducive to the stable hoisting of the prefabricated components by the hoisting device. Summary of the Invention

[0014] According to a second aspect of the present invention, the present invention provides an integrated management and control method for intelligent transportation and hoisting of prefabricated components for prefabricated buildings, the specific steps of which are as follows: S100. Transfer the prefabricated components to the transport equipment and support them stably with the prefabricated component bracket. Then transport the prefabricated components to the assembly site using the transport equipment. S200: The lifting beam is connected to the lifting equipment through the first lifting lug at the top, and the system is started by operating the control panel on the side of the lifting beam. S300: Reliably connect the bottom hook of the wire rope to the preset lifting point of the precast component, drive the servo motor of the drive component to drive the drive screw to rotate, and then drive the adjustment frame to move along the length of the lifting beam to complete the preset initial balance position of the hoisting.

When the industrial camera of the S530 detects that the prefabricated component is tilted, swaying, or there is an obstacle in the hoisting path, it determines that the posture is abnormal or the path is risky.

[0028] like Figure 11As shown, this embodiment provides an integrated intelligent transportation and hoisting management method for prefabricated building components. It utilizes the intelligent transportation and hoisting device for prefabricated building components described in Embodiment 1 to achieve intelligent management of the entire process from transportation to hoisting of prefabricated components. Initially, the prefabricated components are transferred to dedicated transportation equipment. Prefabricated component supports are used to stably support the components, preventing collisions or displacement during transportation. Subsequently, the prefabricated components are safely transported to the prefabricated building assembly site using the transportation equipment, completing the preliminary transportation preparation work.

[0029] Upon arrival at the assembly site, the lifting beam 1 of the intelligent transport and hoisting device for prefabricated building components is reliably connected to the external hoisting equipment via the first lifting lug 12 and the first lifting hole 13 at the top center. The operator operates the control panel 14 on the side of the lifting beam 1 to start the entire system. At this time, the MCU control module inside the lifting beam 1 drives the power supply module to work. The lithium battery in the power supply module supplies power to the dual-axis tilt sensor, tension sensor 5, and industrial camera 7. The charging unit, together with the charging slot 11, can replenish the lithium battery when the power is insufficient. The data acquisition module synchronously collects the initial attitude data of the dual-axis tilt sensor and the no-load tension data of the tension sensor 5. The industrial camera 7 completes the initial image acquisition of the hoisting area. Subsequently, the status evaluation module performs a comprehensive self-check on the communication status of each component of the device, the validity of sensor data, and the stability of the power supply voltage. If an abnormality is detected, the alarm module immediately issues an audible and visual alarm and locates the faulty module, prompting on-site personnel to repair it. After the self-check is normal, the device enters the standby mode.

[0030] After the device completes its self-test, the hook 42 at the bottom of the wire rope 4 is precisely and reliably connected to the preset lifting point of the precast component. The operator manually inputs key parameters such as the weight, size, and center of gravity of the precast component into the MCU control module inside the lifting beam 1 through the control panel 14. The system automatically calculates the theoretical balance position, the rated tension threshold of the wire rope 4, and the safe range of the tilt angle based on the input parameters. Then, the servo motor 31 in the drive assembly 3 starts, driving the drive screw 32 to rotate. Through the cooperation between the drive screw 32 and the threaded hole 24 of the guide block 23 of the adjustment frame 2, the adjustment frame 2 is moved along the length of the lifting beam 1, accurately completing the preset initial balance position for lifting and ensuring that the device is under balanced force before lifting.

[0031] After the initial equilibrium position is preset, the external lifting equipment slowly lifts the intelligent transport and hoisting device for prefabricated building components, driving the prefabricated components to be lifted smoothly. During the hoisting process, the data acquisition module collects three types of core data in real time: real-time tension data of the wire rope 4 monitored by the tension sensor 5, lateral and longitudinal tilt angle data of the lifting beam 1 monitored by the dual-axis tilt sensor, and image data of the prefabricated component posture and the hoisting area environment captured by the industrial camera 7 at an angle. All collected data are transmitted in real time to the MCU control module inside the lifting beam 1 and the remote control terminal via the communication module for real-time monitoring. At the same time, the industrial camera 7 extracts the contour and installation reference features of the prefabricated component through the edge detection algorithm, and calculates the posture deviation of the prefabricated component in real time by combining template matching technology. The deviation accuracy can be controlled within ±5mm, providing data support for precise alignment.

[0032] During data acquisition, the status assessment module integrates tension data, tilt angle data, and image data in real time to comprehensively determine the hoisting status of the precast components. If the data collected by the tension sensor 5 exceeds the preset rated tension threshold, the system determines that there is an overload risk, and the alarm module immediately issues an alarm signal. At the same time, the adjustment control module controls the external hoisting equipment to decelerate, and the drive component 3 fine-tunes the position of the adjustment frame 2 to distribute the force on the wire rope 4 and avoid overload hazards. If the data collected by the dual-axis tilt angle sensor exceeds the preset tilt angle safety range, the system determines that there is an imbalance state. The adjustment control module automatically drives the corresponding end servo motor 31 to move the adjustment frame 2 and dynamically adjust the force balance of the lifting beam 1 until the tilt angle returns to the safe range. If the industrial camera 7 detects that the precast components are tilted, swaying, or there are obstacles in the hoisting path, the system determines that there is an abnormal posture or path risk. The alarm module issues a warning and simultaneously displays the abnormal image on the remote terminal to guide on-site personnel to intervene in a timely manner and ensure hoisting safety.

[0033] After the prefabricated component is hoisted to the installation position, the industrial camera 7 continuously collects images of the installation point in real time. The MCU control module inside the lifting beam 1, based on image recognition technology, accurately compares the positional deviation between the prefabricated component and the installation benchmark, and outputs fine-tuning instructions in the horizontal and vertical directions. The drive component 3 works in coordination with the external lifting equipment to complete the precise horizontal and vertical alignment of the prefabricated component. After alignment, the external lifting equipment slowly lowers the prefabricated component until it falls smoothly into the installation position. After the prefabricated component is fixed and secured by the connector, the connection between the bottom hook 42 of the wire rope 4 and the prefabricated component is released. The operator triggers the system reset command through the control panel 14. The dual-axis tilt sensor, tension sensor 5, and industrial camera 7 stop working, and the intelligent transportation and hoisting device for prefabricated building components returns to the initial state, completing a single hoisting operation.

[0034] After a single hoisting operation is completed, the MCU control module inside the hoisting beam 1 automatically stores all data from the entire hoisting process, including device operating parameters, sensor monitoring data, image information from industrial camera 7, and abnormal alarm records. Subsequently, all data is uploaded to the management and control platform for archiving via the communication module, facilitating subsequent traceability and analysis. The system also automatically generates an operation report and tracks the operating time and number of abnormalities of easily worn components such as tension sensor 5 and industrial camera 7. When the data reaches a preset threshold, a maintenance prompt is issued to remind on-site personnel to maintain and replace components in a timely manner, ensuring the long-term stable operation of the intelligent transportation and hoisting device for prefabricated building components and adapting to the hoisting needs of multiple batches and specifications of prefabricated components.

[0035] In summary, compared with existing technologies, this application incorporates a dual-axis tilt sensor on the lifting beam 1. This sensor monitors the beam's state in real time, and when tilting occurs, the drive assembly 3 adjusts the position of the adjusting frame 2 to balance the load and ensure stable lifting. A tension sensor 5 is installed on the wire rope 4 to measure its real-time tension, preventing it from exceeding its load capacity and causing accidents, thus ensuring sufficient safety during lifting. A mounting frame 6 and an industrial camera 7 are installed on one side of the lifting beam 1. The camera allows for visual monitoring of the prefabricated component lifting process, facilitating timely alarms in case of accidents. This solution is simple in structure, widely applicable, and can lift various prefabricated components while monitoring the lifting status to ensure safety. Furthermore, this lifting device is compatible with various lifting equipment, making it very convenient to use.

The specific steps of this integrated management and control method are as follows: S100. Transfer the prefabricated components to the transport equipment and support them stably with the prefabricated component bracket. Then transport the prefabricated components to the assembly site using the transport equipment. S200, the lifting beam (1) is connected to the lifting equipment through the first lifting lug (12) at the top, and the system is started by operating the control panel (14) on the side of the lifting beam (1); S300, Reliably connect the bottom hook (42) of the wire rope (4) to the preset lifting point of the precast component, drive the servo motor (31) of the drive assembly (3) to drive the drive screw (32) to rotate, thereby driving the adjustment frame (2) to move along the length of the lifting beam (1) to complete the preset initial balance position of the hoisting; S400, lifting equipment hoisting device, drives the precast components to be lifted; data acquisition module collects three types of data in real time and synchronously.

After the prefabricated component is transported to the installation position, the industrial camera (7) collects images of the installation point in real time. The MCU control module compares the positional deviation between the prefabricated component and the installation reference based on image recognition technology and outputs fine-tuning instructions. The drive component (3) works with the lifting equipment to complete the precise horizontal and vertical alignment of the prefabricated component.

When the data from the dual-axis tilt sensor exceeds the safe tilt angle range, the S520 determines that it is in an unbalanced state. The adjustment control module automatically drives the corresponding end servo motor (31) to move the adjustment frame (2) to adjust the load balance of the lifting beam (1) until the tilt angle returns to the safe range. When the industrial camera (7) of S530 detects that the prefabricated component is tilted, swaying, or there is an obstacle in the hoisting path, it determines that the posture is abnormal or the path is risky. The alarm module issues a warning and simultaneously displays the abnormal image on the remote terminal to guide the on-site personnel to intervene.
