Description
Technical Field
[0001] The present invention relates to the technical field of intelligent construction, and particularly to a BIM-based intelligent construction method and system for multi-functional pavers. Background Art
[0002] As a core link in the development of transportation infrastructure, road construction plays a key role in enhancing regional economic vitality and residents' travel experience. As an indispensable equipment in road construction, pavers are mainly used for paving asphalt or concrete pavements, and their construction quality directly affects the flatness, slope and durability of roads. During the paving process, traditional operation methods rely on manual adjustment and manual measurement, which not only increases the labor intensity but also easily generates human errors.
[0003] In recent years, with the rapid development of BIM (Building Information Modeling) technology, its applications in construction, roads and infrastructure construction have gradually increased. Through digital and three-dimensional modeling, BIM technology provides an integrated and visual construction management platform. BIM can model and simulate all aspects of engineering projects, optimize designs, and anticipate potential problems during construction in advance, thereby improving the efficiency and accuracy of construction.
[0004] The application of BIM technology usually depends on the cooperation and data sharing among various departments and teams. However, during the implementation of traditional BIM systems, data updates are often lagged, especially at the construction site. During the construction process, design plans and actual situations often deviate, and these deviations often cannot be immediately fed back and updated in traditional BIM systems. This results in information islands between design documents and actual construction situations, increasing construction errors and the difficulty of adjustment. Summary of the Invention
[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, an object of the present invention is to propose a BIM-based intelligent construction method and system for multi-functional pavers, aiming to solve the problems of traditional paver construction relying on manual labor with large errors, and inaccurate construction caused by the lagging data update of the BIM system. By integrating BIM technology and intelligent control of pavers, real-time monitoring, automatic adjustment and optimization of the construction process are achieved, improving construction quality and efficiency.
[0006] To solve the above problems, the present invention provides a BIM-based intelligent construction method for multi-functional pavers, including the following steps: S1: Create a BIM three-dimensional model of the road, collect road geometric data, environmental data and material data through the BIM three-dimensional modeling module, and generate a BIM model including road geometric shapes, material specifications, hierarchical structures and construction steps; S2: Conduct road surface testing, using the road surface testing module to collect road surface thickness, strength, smoothness and performance indicators, including compressive strength and durability, to provide a data basis for subsequent design; S3: Optimize pavement design. Based on the detection data of S2, the pavement design module performs data processing and analysis to generate optimized construction design and construction plan, including construction steps, material specifications and construction methods. S4: Generate and transmit the construction plan, and send the optimized plan from S3 to the construction site through the server and remote data transmission module to guide the construction preparation; S5: Construction simulation and execution. First, the construction process is virtually simulated through the construction simulation module to identify risks. Then, the paving operation is actually executed. The paver obtains spatial posture information in real time through sensors, compares it with the BIM model, and automatically adjusts its position through the hydraulic system. S6: Road surface performance assessment. After construction is completed, the actual road surface performance indicators are evaluated through the road surface performance assessment module, and the results are fed back to S3 for iterative optimization to form a closed-loop control.
[0007] Preferably, in step S1, detailed road data is imported into BIM modeling software. Using a geographic information system and architectural design tools, a 3D road model matching the real environment is generated. Then, the objective function is set to minimize the curvature change of the road curve, with the curvature function being k(s), where s is a parameter of the path. The curvature k(s) can be expressed by the following formula: in, Represents the geometric curve of the road path in the longitudinal direction. and They are The first and second derivatives.
[0008] Preferably, S5 further includes the following sub-steps: S51: Spatial attitude comparison and control. The system acquires real-time spatial attitude information of the paver through integrated sensors, including the angle and position of each component of the paver. The system compares the above information with the pre-set construction design documents in the BIM model and analyzes the deviation. If the deviation exceeds the set threshold, the system will automatically make adjustments. S52: The control unit works in conjunction with the hydraulic system. The comparison results are transmitted to the system control unit, which then drives the hydraulic cylinders via hydraulic valves to adjust the paver's traction boom based on the comparison results. Specifically, the hydraulic cylinders generate a certain amount of displacement, changing the positions of the paver's left and right traction points, thereby causing the screed to move vertically in the corresponding direction. This adjustment process changes the paver's slope and elevation to ensure that the laying of the fill material meets the design requirements. S53: Meeting construction design requirements, through the above control, the system can accurately adjust various parameters of the paver to ensure that the changes in slope and elevation during road construction conform to the design plan; it improves paving accuracy, reduces human operation errors, and improves the level of intelligent construction. S54: Real-time monitoring and adjustment. During construction, the system continuously monitors the working status and construction progress of the paver and makes fine adjustments based on real-time feedback. If mechanical failure or unexpected changes in the external environment occur, the system will automatically make adjustments or issue an alarm to ensure the accuracy and reliability of the construction process.
[0009] Preferably, in S51, spatial attitude comparison and position error calculation are required. The spatial attitude information of the paver is acquired in real time through sensors. This attitude information is compared with the BIM model in the design documents to determine if there are any deviations, and the ideal attitude of the paver is set as... and The actual posture is and The attitude error can be calculated using the following formula: in, This indicates the deviation of the paver's angle. This indicates the height deviation of the screed; the above error reflects the degree of deviation between the paver and the design requirements. After calculating the error, the system makes adjustments.
[0010] Preferably, during hydraulic system control and position adjustment in S52, the paver's hydraulic system is used to precisely control the position of the traction boom, thereby adjusting the height of the screed. Assuming the length of the paver's traction boom is L, the vertical displacement of the screed... Displacement of the traction boom The relationships between them can be calculated using geometric relationships; This is the actual angle of the traction boom. The ideal angle is represented by the formula above, which indicates that the angle of the traction boom is adjusted via the hydraulic system, thereby controlling the vertical height of the ironing board. The required displacement can be precisely calculated using this formula. This, in turn, drives the hydraulic cylinder to make adjustments.
[0011] Preferably, during the real-time monitoring and adjustment process in S54, after calculating the position error and adjustment amount, the hydraulic control system controls the precise displacement of the traction boom through the oil cylinder. The actual position after each adjustment is compared with the target position. If there is a deviation, the system will continue to fine-tune according to the set control algorithm. The proportional-integral-derivative (PID) control algorithm is used to dynamically adjust the system control accuracy. Error compensation and adjustment are achieved through the following formula: in, For control signals, Error value (position error) ), These are proportional, integral, and derivative gains, respectively. The control system adjusts the output of the hydraulic system according to changes in error, ensuring that the paver corrects itself in real time and maintains the target posture during construction.
[0012] An intelligent construction system used in a BIM-based intelligent construction method for multi-functional pavers includes: The BIM 3D modeling module is used to create and optimize road BIM models; The road surface detection module is used to detect road surface data and performance indicators. The road surface design module is used to process test data and generate construction plans; The construction simulation module is used to virtually simulate the construction process. The remote data transmission module is used to transmit the construction plan to the construction site; Road construction module, including a paver, for performing paving operations; The construction supervision module is used to monitor construction data in real time. The server is used to coordinate the data flow between modules and control the construction process. The road surface performance assessment module is used to evaluate construction quality. The database is used to store BIM models, inspection data, construction plans, and monitoring data. The modules are integrated through a server to achieve closed-loop intelligent control from BIM modeling, inspection, design, simulation, construction to supervision.
[0013] The advantages of this invention compared to the prior art are: 1. This invention utilizes a BIM-based intelligent construction system for multi-functional pavers used in road expansion. Combining spatial posture comparison with a hydraulic automatic adjustment mechanism, it enables precise control of each operational step of the paver during construction. By acquiring the paver's spatial posture information in real time and comparing it with the BIM model in the design documents, the system can promptly detect posture deviations and automatically adjust the paver's working state via the hydraulic system. This technology not only improves construction accuracy but also reduces manual intervention and human error, ensuring the precision of each construction step. By continuously adjusting the paver's angle and position, it ensures that the slope and elevation of the paving material meet design requirements, thereby significantly improving the level of intelligent construction and execution accuracy. 2. This invention utilizes a construction simulation module, enabling virtual simulation before construction to identify potential risks and optimize construction paths and steps. This technology facilitates information sharing, linkage, and collaboration, improving construction efficiency and reducing resource waste. During actual construction, the system monitors the paver's status in real time, ensuring each step meets design requirements and avoiding deviations caused by external environmental changes or mechanical failures.
[0014] 3. This invention combines PID control algorithm and precise hydraulic system regulation, ensuring that each operational step of the paver can quickly respond to the actual needs of the construction process through real-time feedback and target adjustment. This feedback mechanism effectively avoids the accumulation of errors during construction, ensuring the accuracy and stability of the construction. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] This invention discloses a BIM-based intelligent construction system for multi-functional pavers, comprising a BIM 3D modeling module, a pavement detection module, a pavement design module, a construction simulation module, a remote data transmission module, a pavement construction module, a construction supervision module, a server, a pavement performance evaluation module, and a database.

This invention enables the simulation of road expansion construction using BIM technology, continuously updating the design plan based on actual construction conditions until the construction meets performance requirements, resulting in a highly intelligent construction system with high accuracy and reliability and minimal error. The present invention provides a BIM-based intelligent construction method for multi-functional pavers, comprising: S1: Create a BIM 3D model Use the BIM 3D modeling module to create a complete BIM model of the road expansion. The BIM model includes detailed data such as the road expansion's geometry, material specifications, hierarchical structure, and construction steps. The BIM model is the foundation of the entire system, and all subsequent work depends on it. In the process of creating a BIM 3D model, it is first necessary to accurately define and construct the geometry, construction materials, hierarchical structure and construction steps of the road expansion. When creating a BIM model, it is necessary to collect detailed data on existing roads, including road geometry (road width, length, slope, thickness, curvature), performance data of existing materials (soil strength, base layer material properties, etc.), and environmental data of the road expansion area, such as climate conditions, traffic flow and road surface usage. Detailed road data is imported into BIM modeling software, and existing Geographic Information System (GIS) and architectural design tools are used to generate a 3D road expansion model that matches the real-world environment. This model not only includes the road's spatial geometry but also incorporates preset material selection and construction methods, forming a visualized virtual construction environment. By optimizing the design path, abrupt changes in curvature values are reduced, thereby ensuring road comfort and driving safety. The objective function is set as minimizing the curvature change of the road curve. Assuming the curvature function is k(s), where s is the path parameter, the curvature k(s) can be expressed by the following formula: in, Represents the geometric curve of the road path in the longitudinal direction. and They are The first and second derivatives are used. By minimizing the change in the curvature formula mentioned above, the smoothness of the road path is optimized, ensuring a smoother road during use after expansion. In the modeling process, the curvature optimization formula ensures that the geometry of the expanded road meets safety and comfort requirements. Through the above formula, the curvature change of the road is precisely controlled, avoiding overly sharp curves or unsuitable slopes, thereby improving driving safety and comfort.
[0021] S2: Conduct road surface inspection The road surface testing module collects various data about existing roads, including pavement thickness, strength, and smoothness, to obtain road performance indicators, including compressive strength and durability. This testing data provides a foundation for subsequent pavement design optimization.
[0022] S3: Optimized road surface design Based on data obtained from the pavement inspection module, the pavement design module is used for data processing and analysis. Through evaluation and analysis of the existing road performance, the pavement design is optimized. This process ensures that the design scheme meets the actual usage requirements after road expansion. The optimized design scheme includes detailed construction steps, material specifications, and construction methods. S4: Generate construction plan The optimized design plan is transmitted to the server and then sent to the construction site via a remote data transmission module. Construction personnel prepare the necessary materials and equipment according to the system-generated construction plan, ensuring the construction process proceeds as designed.
[0023] S5: Construction Simulation and Execution Before construction, a construction simulation module is used to virtually simulate the construction process, ensuring that no unforeseen problems arise during construction. Simulated operations enable information sharing and coordination, reducing resource waste and improving construction efficiency and safety, while also ensuring that no unforeseen issues occur. Construction simulation ensures that each step meets design requirements and identifies potential construction risks in advance. During actual construction, the system dynamically adjusts the paver's working status by comparing its spatial posture information with the design documents in real time. This includes the following steps: S51: Spatial Attitude Comparison and Control The system acquires real-time spatial attitude information of the paver through integrated sensors, including the angles and positions of various paver components. This information is compared with the pre-set construction design documents in the BIM model to analyze deviations. If the deviation exceeds a set threshold, the system automatically makes adjustments.
[0024] S52: Control unit works in conjunction with hydraulic system The comparison results are transmitted to the system control unit, which, based on the results, drives the hydraulic cylinders via hydraulic valves to adjust the paver's traction boom. Specifically, the hydraulic cylinders generate a certain amount of displacement, changing the positions of the paver's left and right traction points, thereby causing the screed to move vertically in the corresponding direction. This adjustment process changes the paver's slope and elevation, ensuring that the paving material is laid according to design requirements.
[0025] S53: Meets construction design requirements Through the aforementioned controls, the system can precisely adjust various parameters of the paver, ensuring that changes in slope and elevation during road construction conform to the design plan. This improves paving accuracy, reduces human error, and enhances the level of intelligent construction.
[0026] S54: Real-time monitoring and adjustment During construction, the system continuously monitors the paver's working status and construction progress, and makes fine adjustments based on real-time feedback. In case of unexpected situations (such as mechanical failure or changes in the external environment), the system will automatically adjust or issue an alarm to ensure the accuracy and reliability of the construction process.
[0027] During paver construction, a combination of spatial posture comparison and hydraulic automatic adjustment mechanisms is used to precisely control each operation step, ensuring that the road slope and elevation meet design requirements. Specific methods include the following: S500, Spatial Attitude Comparison and Position Error Calculation The paver's spatial posture information (including the angles and positions of various parts) is acquired in real time by sensors. This information is compared with the BIM model in the design documents to determine if there are any deviations, and the ideal posture of the paver is set. and The actual posture is and The attitude error can be calculated using the following formula: in, This indicates the deviation of the paver's angle. This indicates the height deviation of the screed. The above errors reflect the degree of deviation between the paver and design requirements. After calculating the error, the system makes adjustments. S501, Hydraulic System Control and Position Adjustment The paver's hydraulic system is used to precisely control the position of the traction boom, thereby adjusting the height of the screed. In practical applications, there is a certain relationship between the displacement of the traction boom and the vertical displacement of the screed. Assuming the length of the paver's traction boom is L, the vertical displacement of the screed... Displacement of the traction boom The relationships between them can be calculated using geometric relationships; This is the actual angle of the traction boom. This represents the ideal angle. The formula above indicates how the angle of the traction boom is adjusted via the hydraulic system, thereby controlling the vertical height of the ironing board. This formula allows for the precise calculation of the required adjustment displacement. This, in turn, drives the hydraulic cylinder to make adjustments.
[0028] S502, Target Adjustment and Feedback Control After calculating the position error and adjustment amount, the hydraulic control system controls the precise displacement of the traction boom via hydraulic cylinders. Because construction is affected by external factors (such as changes in soil conditions and mechanical deviations), a real-time feedback mechanism is crucial for the adjustment process. The actual position after each adjustment is compared with the target position; if a deviation exists, the system will continue to fine-tune according to the set control algorithm. The proportional-integral-derivative (PID) control algorithm dynamically adjusts the system's control precision, and error compensation and adjustment are achieved through the following formula: in, For control signals, Error value (position error) ), These are proportional, integral, and derivative gains, respectively. The control system adjusts the output of the hydraulic system according to changes in error to ensure that the paver corrects itself in real time and maintains the target posture during construction. Assuming that the ideal angle of the paver's boom is during construction... The actual angle is The length of the traction boom is L=5m. The calculated vertical displacement error of the screed is: Based on the above calculations, the system will automatically adjust the hydraulic cylinders, change the position of the traction boom, and correct the height of the screed to meet design requirements. The hydraulic control system will further fine-tune the system using a PID control algorithm based on the aforementioned error values to ensure that the error is minimized and ultimately achieves the required design accuracy.
[0029] By combining spatial posture comparison with a hydraulic automatic adjustment mechanism, the paver can precisely control the execution of each operational step, ensuring that the road's slope and elevation meet design requirements during construction. Utilizing error calculation formulas, geometric adjustment formulas, and PID control algorithms, the system can calculate and dynamically adjust the paver's position and posture in real time, ensuring the accuracy and stability of each construction stage. Through this precise control method, the system effectively improves the automation level of construction, reduces human error, and ensures construction quality.
[0030] Finally, any aspects not fully described in this invention utilize existing mature products and technologies.
