Description

Technical Field

[0001] The invention relates to the field of building electromechanical pipeline installation, and in particular to a method and system for dividing the length of building electromechanical integrated pipeline modules. Background Art

[0002] With the rapid development of the construction industry, the installation quality and efficiency of building mechanical and electrical integrated pipelines play a vital role in the overall success of the project. Traditional mechanical and electrical pipeline installation methods usually rely on on-site measurements and manual operations. This method is not only time-consuming and labor-intensive, but also prone to installation errors and inconsistencies, which in turn affects the overall quality and aesthetics of the construction project. In order to improve construction efficiency and ensure high-quality installation, modular construction technology has gradually been widely used in the field of building mechanical and electrical.

[0003] The modular installation of building mechanical and electrical integrated pipelines has significant advantages. By prefabricating pipeline modules in the factory and installing them as a whole on the construction site, the accuracy and consistency of the installation can be significantly improved. In addition, modular design is highly flexible and customizable, and can be adjusted according to the specific needs of different buildings to meet various personalized design requirements. With the widespread application of modular construction, the degree of automation and intelligence in the construction process has also been improved, which not only reduces dependence on manual labor, but also optimizes resource utilization and spatial layout during the construction process.

[0004] However, the existing technology still has many shortcomings in the practical application of modular construction. First, the division of module length lacks systematicity and usually relies on empirical judgment. It lacks a scientific basis for division, which easily leads to unreasonable module division, thus affecting the overall construction efficiency. Secondly, the existing division method is not comprehensive enough when considering influencing factors, and often ignores key factors such as the actual situation of the construction site and the real-time cost of materials, making it difficult to meet the needs of complex projects. In addition, the existing technology lacks an effective intelligent optimization algorithm and cannot achieve the optimization of module division under a multi-factor environment, which limits the efficiency and quality of modular construction. Finally, the existing technology lacks an effective method for multi-objective evaluation, making it difficult to comprehensively evaluate the results of module division, which affects the judgment of the pros and cons of the division scheme.

[0005] Therefore, there is an urgent need for a method and system that can systematically and intelligently divide the length of building mechanical and electrical integrated pipeline modules to make up for the shortcomings of existing technologies and further improve the efficiency and quality of modular construction.

[0043] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0044] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0045] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0046] according to Figure 1 The embodiment of the present application provides a method for dividing the length of a building electromechanical integrated pipeline module, comprising the following steps:

[0047] Step 11, determine the key influencing factors of module division, and systematically sort out various influencing factors in the process of module division of building mechanical and electrical integrated pipelines through literature review, expert interviews and data research. Quantify these factors and apply them in the model to ensure the rationality and scientificity of module division.

[0048] Step 12, establish a mathematical model for the modular division of building mechanical and electrical integrated pipelines, and construct a mathematical model based on the analysis and quantification of influencing factors. The model comprehensively considers the costs and constraints of each stage of production, transportation and installation, and provides a theoretical basis for modular division.

[0049] Step 13: Collect and process relevant data, obtain the parameter data required for the model through standard planning, real-time material prices and on-site surveys of construction companies, organize and analyze these data, and convert them into input parameters of the model to ensure the accuracy of the model calculation.

[0050] Step 14, based on the improved genetic algorithm, the improved genetic algorithm is used to optimize the length of the pipeline module based on the above mathematical model. The algorithm gradually approaches the optimal solution through the steps of population initialization, fitness evaluation, selection, crossover, mutation and elite retention, thereby minimizing the cost of module division.

[0051] Step 15, evaluate the optimization results and make adjustments, evaluate the optimization results of the genetic algorithm, including construction cost, transportation cost, installation cost and their comprehensive indicators. If necessary, adjust the algorithm parameters or model input to further optimize the division results.

[0052] Step 16, output the final module division plan, generate the final division plan of the building mechanical and electrical integrated pipeline module based on the optimization results, and provide relevant construction guidance and suggestions for practical application.

[0053] according to Figure 2 The embodiment of the present application shows a building electromechanical integrated pipeline module length division system, which includes the following modules:

[0054] Pipeline information input module: used to input basic information of building mechanical and electrical pipelines, providing data support for subsequent division and optimization. This module is further subdivided into the following functions:

[0055] Pipeline selection function: This function allows users to automatically extract building mechanical and electrical pipeline information from the Revit model, or manually select specific pipelines for operation. Users can select pipeline type, length, location and other information through the interface according to project requirements.

[0056] ·Parameter input function: After selecting the pipeline, the system dynamically generates the corresponding parameter input box. The user can enter various parameters related to the pipeline, such as the diameter, length, load, etc. The input data will be recorded by the system for subsequent calculations and optimization.

[0057] Parameter management function: To improve flexibility, users can add or delete parameter input boxes in the interface as needed to ensure the integrity and flexibility of the input content. The system can update and manage parameters in real time to prevent repeated input or omissions.

[0058] Data submission and storage function: After all parameters are entered, the user submits the data to the system through the submit button. The system automatically collects all parameters and stores them in the database to ensure data security and convenience for subsequent calls.

[0059] The pipeline information input module first selects or manually specifies the pipeline through the user interface and provides the corresponding parameter input function. After the user submits the data, the system automatically stores and prepares it for subsequent support and hanger selection, module division and optimization calculation. It provides basic pipeline data support for the entire system and is the input source for optimization algorithms and subsequent module division. Through this module, the system can ensure accurate building mechanical and electrical pipeline data, which directly affects the calculation of supports and hangers, the division of BIM models and the rationality and accuracy of the final module division.

[0060] Support and hanger calculation and selection module: used to select appropriate support and hanger models according to the mechanical requirements of the building's electromechanical pipeline modules to ensure the stability and safety of the system. This module is further divided into the following functions:

[0061] Load calculation function: This function calculates the load of each layer of pipelines based on the input pipeline parameters, including the width of the bridge and the line load. The system will calculate the maximum bending moment of each layer of crossarms and the corresponding vertical force of the hanger according to the load type (such as uniform load or concentrated force). The system supports the standard support method of two columns. If the support is insufficient,

[0062] The system will automatically add a third column and use the hyperstatic method to calculate the stress conditions of the column.

[0063] ·Support and hanger selection function: The system selects the cross arm and column models that meet the mechanical requirements from the selection table based on the calculated cross arm bending moment and hanger force. The selection of supports and hangers is based on the mechanical design standards of the building, and gives priority to economy and safety. If two columns cannot bear the load, the system will automatically adjust the number of columns and reselect.

[0064] Strength verification function: After the support and hanger selection is completed, the system will perform strength verification to ensure that the selected crossarm and column models can meet the construction requirements under actual load conditions. The verification content includes physical parameters such as bending strength and tensile strength. If the verification result does not meet the specifications, the system will automatically adjust the selection parameters and re-select.

[0065] Result output function: After verification, the system will output the final selection results, including the cross arm bending moment, hanger force, and column quantity and model specifications of each layer of pipelines. The results generated by the system will be provided to the construction team to ensure that the design of the support and hanger meets the mechanical requirements of the project.

[0066] The support and hanger calculation and selection module first inputs basic parameters such as pipeline width and load, and the system automatically calculates the bending moment of the crossarm and the force of the hanger. Then, the system selects the appropriate crossarm and column through the selection table, and performs strength verification on the selection results. This module ensures that the selected support and hanger model can not only withstand the load of the pipeline, but also meet the safety requirements of the building structure. After the results are output, the construction party can install and layout the support and hanger according to the system's suggestions.

[0067] Length division optimization algorithm module for integrated pipeline modules: This module optimizes the length division of the building mechanical and electrical integrated pipeline modules through an improved genetic algorithm, ensuring that the division scheme meets the constraints of construction, transportation, support and hanger layout, and achieves cost minimization and construction efficiency maximization. This module is further subdivided into the following functions:

[0068] Population initialization:

[0069] In the initial stage of the genetic algorithm, the system will generate a set of random initial partitioning schemes, and each individual represents a possible module partitioning method. The length division of each individual must satisfy the total length constraint, that is:

[0070]

[0071] Where L i is the length of the i-th module, L is the total length of the pipeline, and n is the number of modules. standard An initial division is performed, and the remaining part is a non-standard length segment.

[0072] Fitness function evaluation:

[0073] The system evaluates the fitness of the partitioning scheme based on its cost. The fitness function includes various costs such as production, transportation, and hoisting. The specific formula is:

[0074] fitness=C production +C transport +C hoist +penalty

[0075] Among them C production is the production cost, C transport is the transportation cost, C hoist is the lifting cost, and the penalty item penalty is used to penalize unreasonable division (such as cutting at the tee position or too many non-standard lengths).

[0076] Select an operation:

[0077] According to the evaluation results of the fitness function, the system uses the Roulette Wheel Selection method to select individuals with higher fitness as parents. The probability of selection is proportional to the fitness of the individual, ensuring that individuals with higher fitness have a greater chance of being selected. The core formula of the selection operation is:

[0078]

[0079] where p i is the probability of individual i being selected, f(x i ) is the fitness value of individual i, and P is the population size.

[0080] Crossover operation:

[0081] The crossover operation generates new offspring individuals by exchanging some genes of two parent individuals. The selection of the crossover point is based on the length of the pipeline module. The crossover point needs to meet the minimum change requirement. The formula is as follows:

[0082]

[0083] Where k is a random number indicating the position of the crossover. The offspring are generated by combining the genes of the parents to ensure diversity.

[0084] Mutation operation:

[0085] The mutation operation introduces random changes in individual genes to increase the diversity of the population. For the module partitioning problem, the mutation operation will randomly change the length of some modules, and the mutation amount is an integer multiple of the minimum change amount. The formula is:

[0086] new_gene=gene+δ

[0087] Where δ is the variation range, which is randomly generated by standard normal distribution. The mutation operation helps prevent the population from falling into the local optimal solution and improves the global search capability.

[0088] Elite Retention:

[0089] In each generation of evolution, the system retains the individual with the highest current fitness and directly enters the next generation to avoid losing the optimal solution during the evolution process. The purpose of elite retention is to ensure that the algorithm does not degenerate during the iteration process and accelerate convergence to the global optimal solution.

[0090] The workflow of the integrated pipeline module length division optimization algorithm module is to first generate a population and initialize a set of random division schemes; then, the fitness function is used to evaluate the pros and cons of each scheme; then, the system selects the better scheme according to the fitness to perform crossover and mutation operations to generate a new scheme; finally, the elite retention mechanism is used to ensure that the optimal solution will not be lost, and the global optimal solution is approached by evolution generation by generation. The optimization results of this module can not only reduce construction costs, but also improve the efficiency of modular construction, ensure that the division scheme conforms to the actual working conditions, and provide three-dimensional visual construction guidance.

[0091] The BIM model segmentation module of the integrated pipeline module is used to segment the BIM model of the building mechanical and electrical integrated pipeline according to the optimal segmentation scheme generated by the genetic algorithm. The main functions of this module include automatic segmentation of the model, three-dimensional visualization display, and construction guidance after segmentation.

[0092] BIM model segmentation function:

[0093] The module will segment the integrated pipelines in the BIM model according to the module segmentation results output by the optimization algorithm. The segmentation operation will follow the length limit of the segmentation to ensure that the segmentation position will not be located at the tee or other key connection points. The segmentation results will be presented in a 3D visualization form, which is convenient for users to further verify and adjust the segmentation plan.

[0094] Visual display function:

[0095] The divided modules will be presented in different colors or marks in the BIM model to facilitate identification and operation by construction personnel.

[0096] Users can choose to display specific module parts through the interface, or view the overall effect of all segmented modules.

[0097] Construction guidance function:

[0098] Through the three-dimensional segmentation results generated by the system, the construction party can obtain specific construction plans and guidance information to ensure that the segmented modules can be effectively integrated into the actual construction process.

[0099] The logic of the module first obtains the module division scheme from the optimization algorithm, and then applies these divisions in the BIM model to generate the segmented modules and display them in three dimensions. The segmentation results can not only help the construction party to accurately understand the module location, but also guide the on-site construction process to ensure that the segmentation scheme is consistent with the actual construction conditions.

[0100] The connector layout module is used to automatically arrange the connectors between the building mechanical and electrical integrated pipeline modules to ensure stable connections between the modules. The main functions of this module include connector selection, automatic layout and model update.

[0101] Connector selection function:

[0102] Users can select the appropriate connector type through the interface, such as connectors for air ducts, water pipes, and cable trays. The system provides a variety of connector types for users to choose from, and recommends the most suitable connector model based on the type of pipeline module.

[0103] Automatic layout function:

[0104] After selecting the connector type, the system will automatically arrange the connectors between adjacent pipeline modules based on the module's geometric information. This function ensures that the connector layout meets mechanical requirements and avoids conflicts or repeated layouts.

[0105] Model update function:

[0106] After the layout is completed, the system will automatically update the BIM model to show the specific location and type of the connector. Users can view the layout results through the interface and manually adjust the layout of the connector when necessary.

[0107] Support and hanger arrangement module: It is used to arrange the supports and hangers for the modules separated from the BIM model segmentation module of the integrated pipeline module according to the results of the support and hanger selection and calculation modules. This module is further divided into the following functions:

[0108] Arrangement of supports and hangers:

[0109] This function automatically arranges supports and hangers in the BIM model based on the support and hanger selection and calculation results of the calculation module. The system will read the geometric information of the segmented pipeline module and select the appropriate support and hanger layout scheme based on the load requirements of the module. The position and number of supports and hangers arranged on each pipeline module are completely based on the calculated mechanical requirements to ensure the stability and safety of the support system. After the layout is completed, the system will update the BIM model to display the specific position and layout of the supports and hangers for users to conduct 3D visualization inspection.

[0110] ·3D visualization function:

[0111] In the BIM model, users can view each support and hanger arrangement through the 3D visualization function. The system will display the position and status of each support and hanger with different colors or logos to help users quickly identify potential problem areas or check the rationality of the arrangement.

[0112] The support and hanger layout module applies the results of the support and hanger selection and calculation modules to the actual BIM model to ensure that each segmented pipeline module can obtain accurate support. The system not only automatically completes the layout of the supports and hangers, but also ensures that the strength of the support system meets the design specifications through the verification function. At the same time, the 3D visualization display function enables users to more intuitively check and verify the layout results, thereby improving design efficiency and construction safety.

[0113] The module grouping and numbering module is used to batch group and number the divided pipeline modules to ensure that the subsequent management, transportation and construction can be carried out in an orderly manner. The main functions of this module include automatic grouping, numbering rule application, and naming and numbering result output.

[0114] Automatic grouping function:

[0115] The system automatically groups the same type of pipeline modules according to the segmentation results. During the grouping process, the system classifies the modules according to their location, type and size to ensure the consistency of the modules in each group.

[0116] Numbering rule application function:

[0117] Users can enter numbering rules through the interface, such as numbering prefixes, starting numbers, etc. The system will automatically number the elements in each module and group according to the rules defined by the user. The numbering rules are flexible and customizable to meet the needs of different projects.

[0118] Naming and numbering result output function:

[0119] After the numbering is completed, the system will generate a naming and numbering result report, showing the name and number information of each group and module. Users can export the results to Excel or other formats for subsequent construction management and tracking.

[0120] The logic of the modules is first automatically grouped according to the module type and location, and then each module is numbered according to the user-defined rules. After the numbering is completed, the system will store and export the naming and numbering results.

[0121] Performance calculation and evaluation module: This module is used to calculate the comprehensive performance indicators of the system based on the data of the building's mechanical and electrical integrated pipelines, and conduct multi-dimensional evaluations. The system automatically extracts the geometry, load, and support data of the pipelines, and evaluates the safety, durability, and economy of the support system through the built-in calculation model. The calculation results include various mechanical performance indicators (such as bending moment, shear force, tensile strength, etc.), as well as the overall performance of the support system. The module also provides an automated performance evaluation function to ensure that every part of the system meets the relevant standards during the design and construction process.

[0122] Engineering quantity statistics module: This module is responsible for counting the length, weight, cost and other engineering quantity data of the building's mechanical and electrical pipelines, generating detailed statistical reports, and supporting the export of data as Excel files for further analysis. Users can select the pipeline module to be counted through the interface, and summarize its various data (such as pipeline length, diameter, weight, material cost, etc.). The system provides statistical functions for a single module or multiple modules to help construction parties and designers better manage budgets and materials, and improve project management efficiency and accuracy.

[0123] according to Figure 3 The embodiment of the present application provides an implementation process of a building electromechanical integrated pipeline module length division system, which covers the following core links:

[0124] Step 31, before module division:

[0125] Before module division, the system obtains the core parameters of module division through various methods. Ensuring the accuracy and consistency of these parameters is the key to successful module division.

[0126] Step 311, BIM model extraction: Extract basic information related to the pipeline through the BIM model, including the total length of the pipeline integrated module, the coordinate position of the pipeline accessories, boundary information, and geometric parameters such as the width of the module. The automatic extraction function of the BIM model ensures the accuracy and precision of the module division data.

[0127] Step 312: Manual input by the user: The user can manually input parameters related to the genetic algorithm according to project requirements.

[0128] Such as the properties of the lifting machinery, the assembly cost of a single module, the size of the transport vehicle and the available space for on-site transportation.

[0129] These manually entered data ensure that the division model can fully adapt to the actual construction conditions.

[0130] Step 313, manual input + BIM model extraction + automatic conversion: Based on the combination of manual input and BIM model extraction, the system automatically calculates the maximum and minimum module lengths, the cost of single-section connectors, the impact range of pipe accessories, the weight per unit length of the module, and the single-section cutting cost. The automatic conversion function greatly improves the efficiency of data processing during the model division process.

[0131] Step 32, module length division:

[0132] Once the core parameters required for module partitioning are obtained, the system will enter the specific execution phase of length partitioning.

[0133] Step 321, support and hanger selection and verification: First, according to the input pipeline parameters, the system selects and verifies the support and hanger for each module to ensure that the support system can maintain stability and safety under actual load conditions.

[0134] This step is crucial because the selected supports will directly affect the layout and division of the modules.

[0135] Step 322, Genetic Algorithm Calculates Optimal Division Results: After completing the selection of the supports and hangers, the system calculates the optimal module division scheme through an improved genetic algorithm. The algorithm will find the best balance between efficiency and cost based on considerations of construction costs, transportation conditions, and installation restrictions.

[0136] Step 323, dividing the pipeline integrated BIM model according to the optimal division result: the system divides the integrated pipeline BIM model according to the calculated optimal division result. This division operation ensures the accuracy of the module division and provides a clear division basis for subsequent construction steps.

[0137] Step 33, after module division:

[0138] After completing the module division, the system needs to perform a series of processes such as grouping, numbering, connector arrangement and performance evaluation on the divided modules.

[0139] Step 331, manually adjusting the preliminary partitioning model: The partitioned BIM model may not take into account the actual situation on site in some places, and manual adjustment by professionals is required.

[0140] Step 332, grouping and numbering: The segmented BIM model will be automatically grouped and numbered into modules to facilitate subsequent management, transportation and construction. The grouping and numbering rules can be adjusted according to user needs to ensure that each module can be quickly identified at the construction site.

[0141] Step 333, arranging connectors and supports: Next, the system will automatically arrange the connectors and supports required for each module to ensure that the modules can be stably connected and meet the construction requirements.

[0142] Step 334, performance calculation and evaluation: The system will perform performance calculation on the pipeline system before and after the division, and evaluate the impact of the module division on the system performance, including the carrying capacity, stability, and overall operating efficiency of the system.

[0143] Step 335, engineering quantity statistics: Finally, the system counts the engineering quantity of each module and generates a detailed report. These data include the number, length, weight, cost, etc. of modules, which are used for production and construction guidance of pipeline integrated modules.

[0144] Through the above implementation process, the system can efficiently and accurately complete the module division of the building's mechanical and electrical integrated pipelines, ensure that the division plan meets the actual construction conditions, and provide reliable guidance and data support for module construction.
