Description

Technical Field

[0002] Cleanrooms, as core production environments in high-tech industries such as pharmaceuticals, electronics, and biotechnology, require highly specialized and complex design and construction. Traditional cleanroom design primarily relies on two-dimensional drawings and discrete professional software, resulting in fragmented information across disciplines and hindering precise collaboration. This often leads to spatial conflicts and rework. Furthermore, cleanrooms involve a wide variety of functional components, including process equipment, air supply and return systems, and enclosure structures, with complex interface standards. Verification of process compliance and environmental performance is often delayed during the design phase, frequently revealing defects only in the later stages of construction, causing delays and cost overruns.

[0003] With the development of Building Information Modeling (BIM) technology, its advantages in integration, visualization, and parametric design throughout the building lifecycle are gradually being applied to the design of high-precision industrial facilities such as cleanrooms. However, existing BIM applications mostly focus on general building structures and lack dedicated component libraries and design processes to support the modular, standardized, and high-cleanliness requirements specific to cleanrooms, making it difficult to achieve integrated modeling and optimization of the physical structure and process function system of cleanrooms.

[0020] See Figure 1 and Figure 2 The BIM-based cleanroom modular design management system 10 includes a component library module 110, a modeling module 120, a collaborative detection module 130, a model update module 140, a simulation optimization module 150, and an output module 160.

[0021] The component library module 110 is used to establish a parametric family library containing standardized functional components for cleanrooms in the BIM platform; wherein, the standardized functional components are used to constitute the physical structure and process function system of the cleanroom.

[0022] BIM (Building Information Modeling) refers to an information model that integrates the geometric information, functional attributes, and lifecycle management data of a building project into a three-dimensional model using digital technology. Cleanrooms are enclosed spaces that strictly control environmental parameters such as airborne particles, temperature, humidity, pressure, and airflow organization to meet specific process production or experimental requirements; they are commonly found in industries such as pharmaceuticals, electronics, and biotechnology. Standardized functional components refer to predefined cleanroom building units with defined dimensions, materials, performance parameters, and interface types, such as air supply units, return air grilles, wall panels, and process equipment interfaces, used to construct the physical structure and functional system of the cleanroom. Parametric family libraries refer to a collection of components established in the BIM platform containing a series of adjustable parameters. Each component (family) has associated attributes such as dimensions, performance, and connection methods, allowing users to quickly generate component instances of different specifications by modifying parameters.

[0023] Modeling module 120 is used to visualize the assembly and layout of standardized functional components in the BIM platform based on a parametric family library, generating an initial cleanroom model.

[0024] The initial cleanroom model refers to the preliminary three-dimensional model generated in the BIM platform based on a parametric family library through visual assembly and layout operations, reflecting the spatial arrangement and component composition of the cleanroom.

[0025] The collaborative detection module 130 is used to integrate the initial cleanroom model with the pre-established BIM model and perform collision detection to obtain the detection results.

[0026] BIM model refers to a pre-built building information model that includes information on building structure, mechanical and electrical pipelines, HVAC systems, and other professional aspects, used for collaborative analysis and integration with cleanroom model. Collision detection refers to the analysis of whether two or more components have geometric overlap or insufficient spacing in three-dimensional space through algorithms, including two types: hard collision (entity intersection) and soft gap (insufficient safety distance).

[0027] The model update module 140 is used to generate conflict correction instructions based on the detection results and update the initial cleanroom model according to the conflict correction instructions.

[0028] Among them, conflict correction instructions refer to the modification measures automatically generated or suggested by the system based on the collision detection results, such as adjusting the position of components, changing the type of components, and modifying the interface method, which are used to resolve the conflict problems existing in the model.

[0029] The simulation optimization module 150 is used to simulate and analyze the environmental performance parameters of the updated initial cleanroom model and generate optimization suggestions.

[0030] Among them, environmental performance parameters refer to key indicators that affect the operation of cleanrooms, including airflow organization, temperature and humidity distribution, differential pressure control, cleanliness level, and noise level.

[0031] The output module 160 is used to adjust the cleanroom model based on optimization suggestions to obtain the final cleanroom model, and generate engineering data based on the final cleanroom model.

[0032] Among them, engineering data refers to the set of data derived from the final cleanroom model that can be used for construction, procurement, operation and maintenance, such as construction drawings, bill of materials, assembly instructions, performance reports, etc.

[0033] In this embodiment, by constructing an integrated BIM platform and a standardized functional component library, the entire process of cleanroom digital management, from modular design, collaborative testing, conflict correction to performance simulation and data output, is realized. The system supports parametric rapid modeling, multi-disciplinary model integration, and automatic clash detection, effectively avoiding design conflicts and construction rework; through environmental performance simulation and optimization suggestions, it improves the compliance and operational efficiency of cleanroom processes; and finally, it outputs engineering data that can be directly used for construction and operation and maintenance, significantly improving design efficiency.

[0034] In one embodiment of this specification, the modeling module 120 includes: The parameter input unit 121 is used to receive the design parameters of the cleanroom input by the user; Among them, design parameters refer to the initial conditions input by the user to define the basic requirements and specifications of the cleanroom, which typically include, but are not limited to: cleanliness level (such as ISO Class), room dimensions (length, width, height), temperature and humidity range, pressure difference requirements, process equipment layout requirements, personnel and material flow, and other key design inputs.

[0035] The scheme generation unit 122 is used to select corresponding standardized functional components from the parametric family library based on design parameters and generate multiple candidate layout schemes. Among them, candidate layout schemes refer to multiple possible three-dimensional spatial arrangement schemes of the cleanroom generated by the system based on the user-input design parameters, automatically selecting applicable standardized functional components from a parametric family library. These schemes differ in terms of component combination, space utilization, and process organization.

[0036] The performance pre-evaluation unit 123 is used to perform performance evaluation on each candidate layout scheme and obtain each evaluation result; In this context, performance evaluation refers to the preliminary analysis and calculation of each candidate layout scheme during the modeling phase to predict its potential ability to meet design requirements. Evaluation content may include: space utilization, preliminary rationality of airflow organization, accessibility of key equipment, and degree of module standardization, with outputs being quantitative or hierarchical evaluation results.

[0037] The scheme selection unit 124 is used to select the preferred scheme that meets the preset rules from the evaluation results, and load the preferred scheme into a three-dimensional layout model in the BIM platform; Among them, preset rules refer to a series of logical conditions or standards pre-stored in the system for automatic screening and decision-making. These rules may be based on design specifications (such as cleanroom design standards), best practices, cost constraints, or user preferences (such as prioritizing equipment maintenance space). The 3D layout model refers to an interactive 3D visualization model formed after the selected optimal solutions are instantiated and loaded on the BIM platform.

[0038] The model generation unit 125 is used to receive the three-dimensional layout model selected by the user in the BIM platform and solidify it into an initial cleanroom model.

[0039] Among them, "solidification" refers to the process by which the system formally establishes the geometric information, component attributes, and interrelationships of a model as the initial cleanroom model after the user confirms and selects one from multiple 3D layout models.

[0040] In this embodiment, not only is the efficiency and diversity of solution generation significantly improved, but also, through the pre-performance evaluation stage, obviously unreasonable solutions are eliminated in the early design phase, guiding the design towards compliance and optimization.

[0041] In one embodiment of this specification, the collaborative detection module 130 includes: The model integration unit 131 is used to spatially align and fuse the initial cleanroom model with the pre-established BIM model in a unified coordinate system to obtain an integrated model; Spatial alignment refers to the process of accurately locating and matching the initial cleanroom model to the physical spatial position defined by a pre-established BIM model (such as a building structure model) through geometric transformations such as translation and rotation within a unified coordinate system. Data fusion refers to the process of merging and associating the data (including geometric information, attribute information, and relational information) of the two independent models after spatial alignment to create a unified and complete integrated model that includes cleanroom components and existing building / facility components.

[0042] The collision detection unit 132 is used to perform hard collision detection and soft clearance inspection based on the integrated model and output the detection results; the detection results include the collision location, collision type and minimum safe clearance deviation.

[0043] Hard collision detection refers to detecting whether two or more physical components in the model intersect, intrude, or overlap in three-dimensional space. Examples include ducts penetrating beams and equipment colliding with structural columns. Soft clearance detection refers to detecting whether the actual spatial distance between two components in the model is less than the minimum allowable distance (preset minimum safety clearance) that must be reserved for safety, construction, operation, or maintenance of that type of component. Examples include the width of maintenance passages, filter replacement space, and equipment heat dissipation distance. Insufficient clearance, although not a physical overlap, can still affect functionality.

[0044] In this embodiment, hard collision detection and soft gap inspection can systematically identify two key conflicts: physical geometric interference and insufficient functional safety clearance. The system outputs structured detection results including conflict location, type, and quantified deviation. This mechanism achieves deep integration of cross-disciplinary design data and early, accurate conflict diagnosis, exposing potential construction obstacles and operational hazards at the design stage. This significantly improves the accuracy and efficiency of collaborative design for complex cleanroom projects, thus avoiding on-site rework.

[0045] In one embodiment of this specification, hard collision detection and soft gap inspection are performed based on an integrated model, and the detection results are output, including: Geometric overlap is determined between standardized functional components in the integrated model and engineering BIM components in the BIM model. If there is an overlap, it is marked as a hard collision, and the location of the overlap and the type of component involved are recorded. Among them, geometric overlap judgment refers to the calculation process in three-dimensional space to determine whether there is a conflict between entities by calculating and analyzing whether the boundaries, volumes, or surfaces of two or more components intrude or intersect with each other. Engineering BIM components refer to the constituent elements of other engineering disciplines such as architecture, structure, HVAC, water supply and drainage, and electrical systems contained in the pre-established BIM model, such as beams, columns, air ducts, water pipes, and cable trays.

[0046] Determine the shortest spatial distance between component pairs in the integrated model. If the shortest spatial distance is less than the preset minimum safety distance corresponding to the component pair, mark it as a soft gap conflict and record the conflict location, actual distance value and corresponding preset minimum safety distance.

[0047] Among them, soft gap conflict refers to the situation where two components do not overlap physically, but their actual spatial distance is less than the minimum allowable distance (preset minimum safety distance) that is required for the specific type of component to meet the installation, operation, maintenance or safety requirements.

[0048] In this embodiment, by refining the conflict type into hard collision and soft gap conflict, and recording their spatial location, involved components and specific spacing deviation values ​​respectively, the system output detection results are upgraded from qualitative judgment to accurate diagnostic reports containing quantitative data, which effectively improves the reliability of the transformation of the design model into a buildable and operable entity.

[0049] In one embodiment of this specification, geometric overlap determination is performed between standardized functional components in the integrated model and engineering BIM components in the BIM model, including: Standardized functional components and engineering BIM components are converted into boundary representation models or voxel mesh models, respectively. Boundary Representation Model (B-Rep model) is a 3D geometric representation method that defines the precise shape and size of an object by describing the faces (planes or curved surfaces), edges, and vertices that constitute the object's boundary, as well as their topological relationships. Its characteristic is its ability to accurately represent the surface details of complex geometries. Voxel mesh model is a representation method that discretizes 3D space into a set of uniform small cubes (voxels). Each voxel is marked as occupied or unoccupied, and the shape and volume of an object are approximated by combinations of voxels. Its characteristics include a regular data structure, facilitating fast spatial queries and Boolean operations.

[0050] Based on the boundary representation model or voxel mesh model, determine whether there is a three-dimensional spatial overlap between each standardized functional component and each engineering BIM component.

[0051] Among them, the three-dimensional spatial overlap judgment is based on the transformed geometric model (B-Rep or voxel mesh), and uses computational geometry or image processing algorithms to detect whether two objects share a volume or spatial region in the three-dimensional coordinate system.

[0052] In this embodiment, a robust low-level collision detection capability is provided to adapt to different accuracy and performance requirements, ensuring the accuracy and reliability of hard collision recognition.

[0053] In one embodiment of this specification, determining the shortest spatial distance between component pairs in an integrated model includes: Identify component pairs in the integrated model and determine the corresponding distance verification direction based on the functional type of each component pair; wherein, component pairs include adjacent standardized functional components, standardized functional components and engineering BIM components, and standardized functional components and building envelope interfaces; In this context, "component pair" refers to two specific components selected for pairwise relationship analysis during collision or gap detection. "Functional type" refers to the specific role a component plays within the cleanroom system or the subsystem category it belongs to, such as air supply, return air, enclosure, process equipment interfaces, or support structures. The functional type of a component determines the spatial relationship characteristics it needs to maintain with surrounding components. "Distance check direction" refers to the predefined or calculated spatial vector direction used to measure and evaluate the shortest spatial distance between a specific component pair during soft gap checks. This direction is typically perpendicular to the component surface or functional interface where operational or safety space needs to be reserved.

[0054] For each pair of components, determine the projected spacing or normal spacing of the pair of components in three-dimensional space along its corresponding distance verification direction; The projection spacing refers to the distance between two projected areas measured along the distance verification direction when one component is projected onto the plane containing another component or a plane perpendicular to that direction. The normal spacing refers to the distance between two components measured along the normal direction (i.e., perpendicular to the surface) of the component surface at their closest point.

[0055] The projection spacing or normal spacing is taken as the shortest spatial distance between the component pairs.

[0056] In this embodiment, soft gap inspection is no longer a simple global minimum distance calculation, but a directional spatial relationship verification closely related to the actual installation, operation and maintenance requirements of the component. This significantly improves the engineering rationality and practicality of the gap inspection, ensuring that the reserved space truly serves the functional realization and operation and maintenance needs.

[0057] In one embodiment of this specification, the corresponding distance verification direction is determined according to the functional type of each component pair, including at least one of the following: If the component pair includes an air supply component, the vertical upward direction will be determined as the distance verification direction, which is used to verify the hoisting and filter replacement space above the air supply component; If the component pair includes return air components or ground support components, the vertical downward direction will be determined as the distance verification direction, which is used to verify the load-bearing capacity or drainage space of the structure below. If the component pair includes wall panels and pipeline engineering BIM components, the horizontal lateral direction will be determined as the distance verification direction to verify the sealant application width and maintenance access on the outside of the wall panels. If the component involves the interface component of the process equipment and adjacent components, the distance verification direction is determined according to the preset maintenance opening orientation of the interface component of the process equipment.

[0058] Among them, air supply components refer to the functional units in a cleanroom air handling system responsible for delivering filtered and regulated air into the room, such as HEPA / ULPA filter diffusers and fan filter units (FFUs). Space is usually reserved above them for hoisting, filter replacement, and maintenance. Return air components refer to the units in a cleanroom air handling system responsible for returning indoor air to the handling equipment, such as return air grilles and return air walls. The structural load-bearing capacity, airflow channels, and possible drainage requirements must be considered below them. Ground support components refer to the bases and brackets used to support equipment, floors, or structures within the cleanroom. Their installation must ensure sufficient structural load-bearing space and possible space for pipeline avoidance. Enclosure wall panels refer to the sheet metal components that constitute the sealed enclosure structure of the cleanroom. Space is often reserved on the outside for applying sealant, laying pipelines, or setting up maintenance access. Piping engineering BIM components refer to linear laying facilities such as air ducts, water pipes, cable trays, and process piping represented in the BIM model. Process equipment interface components refer to the standardized interface parts reserved on process equipment (such as reactors, filling machines, etc.) in clean rooms for connecting media, power, or signals. Their orientation determines the direction of maintenance and operation. Maintenance opening orientation refers to the direction of openings or accessible surfaces on process equipment designed for inspection, replacement of parts, or routine operation.

[0059] In this embodiment, the soft gap inspection can be closely integrated with the actual physical constraints and operation and maintenance requirements of the cleanroom project, which significantly improves the accuracy and pertinence of the system’s automatic gap compliance verification. This ensures that every reserved space has a clear functional meaning, thereby eliminating construction difficulties or operation and maintenance obstacles caused by insufficient operating space in advance during the virtual design stage, and enhancing the constructability and maintainability of the design results.

[0060] In one embodiment of this specification, the model update module 140 is further configured to: Based on the conflict type in the detection results, the corresponding conflict correction instructions are matched from the preset correction rule library; the correction rule library stores displacement tolerances, replacement schemes and interface adjustment strategies for different standardized functional components. Execute the matching conflict correction instruction.

[0061] Among these, "conflict type" refers to the specific problem category identified in collision detection and soft clearance inspection, such as hard collision, soft clearance conflict (upward direction, difference from the required value X mm), etc. This type is usually associated with a specific component category and spatial relationship. "Correction rule base" refers to a predefined, structured knowledge base or database that stores a set of standardized solutions or correction strategies for different types of conflicts. "Displacement tolerance" refers to the maximum range or degrees of freedom allowed for positional adjustments (such as translation or rotation) of a certain type or specific standardized functional component when resolving conflicts; exceeding this range may affect system functionality or installation. "Alternative solutions" refers to the list of alternative functional component models provided by the system when repositioning cannot resolve conflicts, offering different specifications (such as smaller sizes), interface types, or installation methods. "Interface adjustment strategy" refers to modification schemes for the connection relationships between components, such as changing connector models, modifying connection angles, adjusting the routing and port positions of pipes or lines, etc.

[0062] In this embodiment, the system can generate targeted conflict correction instructions that conform to engineering practice based on the root causes of different conflicts (physical interference or insufficient functional spacing) and the characteristics of the components involved. This greatly improves the efficiency and quality of design iteration, reduces human error, and ensures the consistency and compliance of the correction scheme.

[0063] In one embodiment of this specification, the simulation optimization module 150 includes: The simulation environment configuration unit 151 is used to configure the simulation conditions and evaluation indicators for the performance simulation of the updated cleanroom model. The simulated operating conditions refer to a set of boundary conditions and operating parameters preset for simulation calculations, used to simulate the operation of a cleanroom under specific actual or standard conditions. Examples include: different outdoor weather conditions, indoor equipment heat generation, personnel activity, filter resistance changes, and different air supply modes. Evaluation indicators refer to a series of key parameter standards or target values ​​used to quantitatively assess whether the cleanroom's environmental performance meets standards. These are typically derived from design specifications, owner requirements, or process requirements, such as: temperature range, humidity range, cleanliness level (particle concentration), pressure gradient (pressure difference), airflow velocity uniformity, and self-cleaning time for specific measuring points or areas.

[0064] The simulation calculation unit 152 is used to simulate the environmental performance of the cleanroom model based on simulated operating conditions and obtain simulation results. Environmental performance simulation refers to the process of predicting and calculating the distribution and changes of environmental parameters such as airflow organization, temperature field, humidity field, and pollutant concentration field inside a cleanroom using numerical simulation techniques such as computational fluid dynamics (CFD) based on physical laws (mass, momentum, energy conservation, etc.) and mathematical models. Simulation results refer to the data set output after the environmental performance simulation calculation is completed, which includes the detailed distribution and calculation results of various physical fields (such as velocity, temperature, pressure, and concentration) at various spatial locations in the cleanroom model under the set simulation conditions.

[0065] The optimization suggestion unit 153 is used to compare the simulation results with the evaluation indicators and generate corresponding optimization suggestions based on the comparison results.

[0066] In this embodiment, the overall environmental performance of the cleanroom is predicted and visualized in a virtual environment. By automatically comparing it with preset target indicators, design defects or potential non-compliance areas are identified, and targeted optimization suggestions are generated. This significantly improves the scientificity and reliability of cleanroom design in meeting the requirements of complex process environments, and avoids the risk of rework or low operational efficiency caused by airflow, temperature and humidity, and cleanliness not meeting the requirements from the source.

[0067] In one embodiment of this specification, the output module 160 includes: The model adjustment unit 161 is used to adjust the cleanroom model based on optimization suggestions to obtain the final cleanroom model; Model format unit 162 is used to perform format conversion of the final cleanroom model to adapt it to downstream applications; Downstream applications refer to various engineering activities that directly utilize the final model data after the engineering design phase. These mainly include construction (such as prefabrication and on-site assembly guidance), procurement (such as quantity surveying and bill of materials generation), and operation and maintenance management (such as facility management and space management). Format conversion refers to the process of exporting or converting the final cleanroom model containing complete information from the BIM platform into specific file formats (such as IFC, DWG, NWC, PDF 3D, etc.) according to the data interface requirements of different downstream application software or systems, to ensure data transferability and usability.

[0068] The model output unit 163 is used to generate construction drawings based on the converted model data.

[0069] Construction drawings refer to two-dimensional or three-dimensional drawing documents (such as floor plans, elevations, sections, and details) generated based on the final cleanroom model through automatic annotation, sectioning, view arrangement, and drawing layout, which conform to engineering drawing specifications and output standards. They are used to guide on-site construction and installation.

[0070] In this embodiment, a seamless connection and data-driven approach were achieved from virtual design optimization to physical construction implementation, thereby improving the overall project delivery efficiency and construction quality.

[0071] Based on the same general inventive concept, this invention also protects a BIM-based modular design and management method for cleanrooms, such as... Figure 3 As shown, Figure 3 This is a flowchart illustrating the BIM-based modular design management method for cleanrooms provided in this embodiment of the invention.

The BIM-based modular design management method for cleanrooms can be applied to any of the BIM-based modular design management systems described in the above embodiments.

[0072] The BIM-based modular design management method for cleanrooms includes the following steps.

[0073] Step 301: Establish a parametric family library containing standardized functional components for cleanrooms in the BIM platform; wherein, the standardized functional components are used to constitute the physical structure and process function system of the cleanroom.

[0074] Step 302: Based on the parametric family library, perform visual assembly and layout of standardized functional components in the BIM platform to generate an initial cleanroom model.

[0075] Step 303: Integrate the initial cleanroom model with the pre-established BIM model and perform collision detection to obtain the detection results.

[0076] Step 304: Generate conflict correction instructions based on the detection results, and update the initial cleanroom model according to the conflict correction instructions.

[0077] Step 305: Perform environmental performance parameter simulation analysis on the updated initial cleanroom model and generate optimization suggestions.
