Description

Technical Field

[0001] This invention belongs to the field of building engineering technology, and specifically relates to a prefabricated component production management system. Background Technology

[0002] As a core component of prefabricated buildings, the production efficiency and management precision of prefabricated components directly determine the project quality and construction cycle. With the acceleration of building industrialization, BIM (Building Information Modeling) technology has been widely applied to the design and production of prefabricated components. By integrating information such as component geometric parameters and material properties through digital modeling, it provides data support for factory production and promotes the transformation of the construction industry from traditional extensive management to a refined collaborative model.

[0003] However, the application of BIM models in existing technologies is mostly limited to the design phase, lacking sufficient coordination with production execution and on-site installation. On the one hand, modifications to the design model are difficult to be fed back to the production process in real time, easily leading to a disconnect between component production and on-site needs due to information lag, resulting in rework or resource waste. On the other hand, interference detection during component installation is mostly limited to static spatial conflict analysis, lacking dynamic collision warnings caused by construction sequence (such as installation order and schedule deviations), and the visualization of interference results is low, making it difficult to guide production adjustments. In addition, the production traceability of prefabricated components relies heavily on manual records, resulting in a broken data chain throughout the entire lifecycle, making it impossible to achieve full traceability from raw material arrival to installation and acceptance. This leads to pain points in prefabricated component production management, such as delayed response, inefficient coordination, and insufficient risk control, making it difficult to meet the needs of modern prefabricated buildings for rapid iteration and precise control.

[0004] Therefore, the present invention proposes a prefabricated component production management system to at least partially solve the above-mentioned problems. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides a prefabricated component production management system, which solves the problems of isolated response mechanisms and lack of real-time collaboration mechanisms and dynamic optimization strategies when modifying building information.

[0006] The objective of this invention can be achieved through the following technical solution: a precast component production management system, comprising: a BIM model integration module for integrating BIM models, wherein the BIM model integration module is associated with the production schedule plan and receives actual production progress data in real time, and can also extract the geometric parameters, material properties and connection node information of the components to generate initial production data; The scene matching module is used to pre-import the installation scene of the BIM model, in which the original BIM model storage unit is arranged to simulate the actual installation environment; the scene matching module is also used to combine the actual production progress data to detect the temporal interference and spatial interference between the BIM model and the original BIM model storage unit at different construction stages, and determine the interference location and degree. The BIM model integration module is also used to parametrically modify the original BIM model stored in the unit basic components that constitute the BIM model according to the interference location, interference degree and production progress deviation, and regenerate optimized production data that adapts to the production progress. The production monitoring module is used to associate the prefabricated components produced with the original BIM model base components by generating unique electronic tags, thereby achieving full lifecycle traceability.

[0007] As a preferred technical solution of the present invention, the BIM model integration module is equipped with a version control unit for recording the iteration history of the BIM model. The version control unit supports incremental updates and parallel comparison of multiple versions, and can associate the production data and progress deviation records of the corresponding version to ensure that model changes are traceable.

[0008] As a preferred technical solution of the present invention, the BIM model integration module digitizes the geometric parameters, material properties and connection nodes of the components in the model into production data, and can dynamically update the cost budget according to the fluctuation of material market prices.

[0009] As a preferred technical solution of the present invention, the interference detection results of the scene matching module generate a three-dimensional heat map. The heat map uses color gradients to represent the degree of interference, and the heat map can be superimposed to display the progress nodes of the corresponding construction stage.

[0010] As a preferred technical solution of the present invention, the temporal interference analysis of the scene matching module supports hypothesis and verification simulation. That is, after inputting different installation sequence schemes, the system automatically calculates the interference probability and the impact on the construction period of each scheme and outputs the optimal installation sequence suggestion.

[0011] As a preferred embodiment of the present invention, the production monitoring module includes a production management sub-module, which is used to intelligently allocate the repair priority of prefabricated components, warehouse transfer paths, and re-production schedules based on optimized production data.

[0012] As a preferred technical solution of the present invention, the production monitoring module further includes a real-time feedback submodule, which is used to collect and visualize equipment operating parameters, quality inspection data and progress deviations in the production process in real time.

[0013] As a preferred technical solution of the present invention, the electronic tag of the production monitoring module is also associated with raw material traceability information and production process records, and the entire process data of the component from raw materials to finished products can be viewed by scanning the code.

[0014] The beneficial effects of this invention are as follows: End-to-end collaborative optimization: The BIM model integration module is linked to the schedule plan, dynamically extracts data to generate and optimize production data, breaks down information barriers between design and production, and adapts to schedule deviations; the scenario matching module detects interference during the construction phase, combines simulation output solutions to ensure installation collaboration, and reduces rework.

[0015] Precise cost and quality control: The model integration module updates the cost budget based on market fluctuations to help control costs; the production monitoring module collects production data in real time and displays it visually to facilitate quality and progress supervision; electronic tags link information throughout the entire process to achieve full lifecycle traceability of components and improve management transparency and credibility.

[0016] Intelligent decision support: The version control unit ensures traceability of model changes and provides data support for decision-making; the simulation function of scenario matching and the intelligent allocation of production management sub-modules assist in efficient decision-making, improve the efficiency and scientific nature of production management, and promote the development of prefabricated component production towards refinement and intelligence.

Detailed Implementation

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0020] Example 1 This embodiment provides a precast component production management system applicable to the entire production management of precast concrete slabs, steel beams, and other components in prefabricated buildings. Precast components are building components prefabricated in factories or specific locations outside the construction site and then transported to the construction site for installation. These components include various types such as concrete, steel structures, and wood. While the widespread use of precast components can shorten construction cycles, improve project quality, and reduce construction costs, precast component production management faces numerous challenges, such as unreasonable production planning and inefficient resource allocation, leading to reduced production efficiency and project delays. Existing Building Information Modeling (BIM) technologies are mostly concentrated in the design phase, with relatively isolated response mechanisms to changes in building information, lacking real-time collaboration mechanisms and dynamic optimization strategies. This situation results in inefficient production management, failing to meet the demands of the modern construction industry for rapid response and efficient collaboration.

[0021] For the above issues, please refer to Figure 1 This invention provides a prefabricated component production management system, which specifically includes the following: The BIM model integration module, serving as the core hub for design data in the prefabricated component management system, is linked to the production schedule of the project management platform, receiving real-time progress data from the production line. Simultaneously, it extracts geometric parameters, material properties, and connection node information of components from the BIM model, automatically generating initial production data to provide precise guidance for component production. When the scene matching module reports interference issues, this module can also make targeted modifications to the basic components of the BIM model based on the interference, re-outputting production data to ensure the timeliness and accuracy of system data and prevent a disconnect between production and design.

[0022] The scene matching module pre-imports installation scenarios containing the original BIM model's stored units, constructing a highly realistic virtual construction environment to comprehensively simulate actual installation conditions. Combining actual production progress data, it dynamically detects dual interference between the new BIM model and the original BIM model's stored units at different construction stages: identifying dimensional conflicts (spatial interference) between components through a geometric collision algorithm, simulating installation sequence and collisions caused by overlapping processes (temporal interference) based on the schedule plan, accurately locating interference points and assessing the degree of interference, providing a basis for component modification.

[0023] It should be noted that the spatial interference detection of the scene matching module adopts a geometric collision algorithm. Through mesh modeling, boundary box collision detection, and precise geometric comparison, it quantifies the volume ratio or minimum distance of the overlapping area to assess the degree of interference. The temporal interference detection uses a process simulation algorithm based on the time axis to construct a process time axis model, iteratively calculates the real-time position of the components according to the time step, and combines priority weights to detect spatial overlap within the time window. The two types of algorithms are linked through a data interface to jointly generate a comprehensive report containing the three-dimensional coordinates of the interference parts, time nodes, and degree assessment. This provides accurate input for the parametric modification of the BIM model integration module and ensures the real-time performance and accuracy of interference detection.

[0024] The production monitoring module acts as an intelligent supervisor of the production process. It generates unique electronic tags (integrating RFID chips and QR codes) for prefabricated components, linking them to the IDs of the corresponding basic components stored in the original BIM model. This enables full lifecycle traceability from "raw material arrival - factory production - warehousing and transportation - on-site installation." Simultaneously, it monitors production progress, equipment status, and quality inspection data in real time. Any anomalies trigger immediate alarms and feedback for timely adjustments. Furthermore, based on actual production conditions, it can rationally allocate component repair, relocation, and re-production, optimizing resource allocation and improving production efficiency and product quality.

[0025] Example 2 Please see Figure 1-2 This embodiment provides supplementary explanations of the detailed functions of each module in the system: The BIM model integration module features version control and cost linkage. The BIM module is equipped with a version control unit that records the iteration history of the BIM model through incremental updates, supports parallel comparison of multiple versions, and can link production data and schedule deviation records for corresponding versions, enabling full-process traceability of model changes. Simultaneously, this module digitizes the geometric parameters, material properties, and connection nodes of components in the model into production data and can connect to a building materials market price database. When the prices of main materials such as steel bars and cement fluctuate beyond a preset threshold, the cost budget is automatically updated, forming a data closed loop from design to production. This ensures accurate matching between precast component production and design intent, aiding in cost control.

[0026] The scene matching module's visualization and simulation functions, after detecting interference between the BIM model and the original BIM model's stored units, visualize the interference data to generate an intuitive 3D heatmap. The system assigns different color gradients based on quantitative indicators such as the volume ratio and spatial overlap of the interfering parts: red indicates severe interference (potentially significantly inconsistent with the BIM model), yellow indicates moderate interference (some degree of spatial conflict requiring adjustment of prefabricated components), and green indicates minor interference (minor potential interference with minimal overall impact). This intuitive visualization allows engineers to quickly locate interference points and assess their severity, providing a clear and efficient basis for subsequent modifications to prefabricated components and adjustments to construction plans.

[0027] Meanwhile, the temporal interference analysis of the scene matching module supports hypothesis and verification simulation. Based on the time dimension information of the BIM model, it dynamically correlates the construction schedule with the spatial location data of components. Using the timeline as a guide, it simulates the hoisting, installation, and splicing processes of components at each stage according to the construction procedures and schedule. After the user inputs multiple installation sequence schemes, the system calculates and displays the spatial position of the components at different times in real time by setting time intervals (such as by day, week, or specific construction nodes). It accurately analyzes the spatial relationship between the components and surrounding structures, equipment, and other components, automatically calculates the interference probability of each scheme and its impact on the overall construction period, and outputs the optimal installation sequence suggestion. Once it is found that the movement trajectory or final position of a component in a certain construction stage may collide with the existing structure, the system will trigger an early warning mechanism, specifying the time node of the collision, the components involved, and the possible impact, helping the construction party to adjust the construction sequence in advance and reduce delays and rework.

[0028] The intelligent management functions of the production monitoring module specifically include the following module information: Production Management Submodule: This module leverages the interconnected data between components and the BIM model to construct an intelligent scheduling system. Based on optimized production data, it prioritizes the repair of substandard components according to the critical path priority principle (e.g., prioritizing components that affect subsequent processes). It optimizes transport routes using a shortest path algorithm based on real-time warehouse inventory and on-site demand (reducing transportation time). It automatically inserts scrapped components into the re-production schedule (e.g., inserting them into the next day's pouring plan), simultaneously adjusting production resource allocation to ensure timely and accurate delivery of components to the construction site.

[0029] Real-time feedback submodule: Through sensors and data acquisition terminals deployed at various stages of the production line, information such as production parameters (e.g., concrete mixing temperature, mold vibration frequency), equipment status, and quality inspection results are collected in milliseconds. Once abnormal data or production bottlenecks occur (e.g., dimensional deviations, insufficient strength), the system immediately feeds back warning information and detailed data to management personnel, technical personnel, and frontline operators through multiple channels, including audible and visual alarms, mobile app push notifications, and enterprise management system pop-ups. Simultaneously, it coordinates with the production management submodule to quickly adjust production strategies, achieving closed-loop management of the entire process from problem discovery to resolution, ensuring the efficient and stable operation of the precast component production process based on the modified BIM model.

[0030] Extended functions of electronic tags: Tag information is dynamically updated with the production process, and can be linked to raw material traceability information (such as supplier qualifications and factory inspection reports) and production process records (such as operators and equipment numbers). By scanning the code, you can view the entire process data of the component from raw materials to finished products, which meets the needs of project acceptance traceability.

[0031] In summary, this invention constructs a digital management system covering the entire process of prefabricated component "design-production-installation" through the collaborative operation of a BIM model integration module, a scene matching module, and a production monitoring module. This system innovatively links the BIM model with production progress and on-site installation scenarios, solving the problem of insufficient design-production collaboration through temporal and spatial dual interference detection and parametric modification; it enhances the intuitiveness of interference warnings and decision-making efficiency by leveraging 3D heatmap visualization and installation sequence simulation; and it breaks through the limitations of traditional manual recording by enabling full lifecycle traceability through electronic tags, ensuring data traceability.

[0032] This system, through refined functions such as version control, cost linkage, and intelligent scheduling, achieves precise and intelligent management and control of prefabricated component production, effectively reducing rework rates, optimizing resource allocation, and improving project quality. It provides technical support for the efficient construction of prefabricated buildings and has significant engineering application value and promotion prospects.
