Technical Field

[0001] This application relates to the field of digital construction technology, and in particular to a method, apparatus, computer equipment, storage medium and computer program product for duct demolding applied to building information modeling. Background Technology

[0002] With the development of computer software technology, the technology of building information modeling using computers has emerged. Building information modeling uses various relevant information and data of a building project as the basis for building model creation, and it is now widely used in architecture, engineering, and civil engineering fields.

[0003] Before being used to assist in on-site construction, Building Information Modeling (BIM) requires ductwork dismantling. Traditionally, this is done by manually inputting the values ​​of the pipe components. However, this method is easily affected by factors such as the experience and condition of the personnel, making it difficult to ensure that the pipe components in the BIM are standard parts that are easy to manufacture in a factory. This results in a low accuracy rate for ductwork dismantling in current technologies. Summary of the Invention

[0015] Among the evaluation scores of the multiple candidate duct demolding schemes, the highest evaluation score is determined; the candidate duct demolding scheme corresponding to the highest evaluation score is identified as the candidate duct demolding scheme with the corresponding optimal evaluation result.

[0016] In one embodiment, the method further includes:

[0017] If any of the evaluation conditions in the basic evaluation conditions and the bonus evaluation conditions for duct formwork removal change, the target duct formwork removal scheme corresponding to the duct construction plan shall be re-determined based on the changed evaluation conditions.

[0018] In one embodiment, the method further includes:

[0019] Upon receiving feedback information regarding the target duct demolding scheme, the feedback information is recorded, and the target duct demolding scheme is updated based on the feedback information. Based on the updated target duct demolding scheme, the duct structure information in the initial building information model is adjusted to obtain the target building information model.

[0020] Secondly, this application also provides a duct demolding device for use in building information modeling. The device includes:

[0021] The information acquisition module is used to acquire the duct construction plan and the preset duct demolding evaluation conditions; the duct demolding evaluation conditions include the basic evaluation conditions for duct demolding and the bonus evaluation conditions for duct demolding.

[0022] The scheme formulation module is used to obtain multiple candidate duct formwork removal schemes that meet the basic evaluation conditions for duct formwork removal based on the duct construction plan.

[0023] The scheme evaluation module is used to obtain the evaluation results of each of the multiple candidate duct demolding schemes under the duct demolding bonus evaluation conditions;

[0024] The scheme selection module is used to select the candidate duct demolding scheme with the best evaluation result from the multiple candidate duct demolding schemes based on the evaluation results, and use it as the target duct demolding scheme corresponding to the duct construction plan.

[0031] The aforementioned method, apparatus, computer equipment, storage medium, and computer program products for duct formwork removal applied to Building Information Modeling (BIM) acquire duct construction plan drawings and preset duct formwork removal evaluation conditions, which include basic duct formwork removal evaluation conditions and bonus evaluation conditions. Based on the duct construction plan drawings, multiple candidate duct formwork removal schemes that meet the basic duct formwork removal evaluation conditions are obtained. The evaluation results of each of the multiple candidate duct formwork removal schemes are obtained under the bonus evaluation conditions. Based on the evaluation results, the candidate duct formwork removal scheme with the optimal evaluation result is selected from the multiple candidate duct formwork removal schemes as the target duct formwork removal scheme corresponding to the duct construction plan drawings. In this way, by initially screening duct demolding schemes based on the basic evaluation conditions for duct demolding, and then conducting a second screening of the candidate duct demolding schemes based on the bonus evaluation conditions for duct demolding, the requirements of the duct demolding evaluation conditions can be met to the greatest extent. This allows for the development of targeted duct demolding schemes that meet both mandatory conditions and the personalized needs of users, thereby avoiding the need to manually input the values ​​of pipe components and improving the accuracy of duct demolding.

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] In one embodiment, such as Figure 1 As shown, a method for duct demolding applied to building information modeling is provided. This embodiment illustrates the application of this method to a terminal. It can be understood that this method can also be applied to a server, and can also be applied to a system including a terminal and a server, and can be implemented through the interaction between the terminal and the server.

[0039] Among them, such as Figure 2 As shown, Building Information Modeling (BIM) uses various relevant information and data of a building project as the foundation for building model creation. It simulates the real-world information of a building through digital information, including three-dimensional geometric information such as the materials, performance, price, weight, location, and schedule of building components. This significantly improves efficiency and reduces risks throughout the entire construction process, supporting project lifecycle construction, operation, and management. It possesses five key characteristics: visualization, coordination, simulation, optimization, and the ability to generate drawings.

[0040] Demolding refers to breaking down a complete section of ductwork (a piping system used for air transport and distribution) into individual components, making them as easy as possible to prefabricate in a factory.

[0041] The terminal can be, but is not limited to, various personal computers, laptops, smartphones, tablets, etc.; the server can be a standalone server or a server cluster composed of multiple servers. In this embodiment, the method includes the following steps:

[0042] Step S101: Obtain the duct construction plan and the preset duct demolding evaluation conditions; the duct demolding evaluation conditions include the basic evaluation conditions for duct demolding and the bonus evaluation conditions for duct demolding.

[0043] Among them, the duct construction plan refers to the CAD (Computer Aided Drafting) drawings for duct construction.

[0044] The basic evaluation conditions for duct formwork removal include mandatory conditions and basic conditions. Mandatory conditions are the existing, promulgated, and mandatory provisions that must be met, such as the requirement that ducts must be fitted with sleeves when passing through fire compartments. Basic conditions are also relatively basic and must be followed. For example, during testing, it was found that when both the basic evaluation conditions and the bonus evaluation conditions for duct formwork removal in the evaluation framework are met simultaneously, the ductwork deviates too much from the original CAD drawings. For instance, the ductwork layout in a long corridor might, in order to meet the requirements, pass through walls to other rooms, making multiple turns before returning. While this is indeed the optimal solution, it fails to meet the requirements in terms of economy and aesthetics. Therefore, several instructions are combined into the "basic conditions" framework, requiring that the obtained duct formwork removal scheme does not deviate too much from the CAD drawings, while also taking into account economic factors. The original collision test is also included in this "basic conditions" framework, with avoiding collisions being one of the most basic requirements.

[0045] The evaluation criteria for duct demolding include a first bonus condition and a second bonus condition. The first bonus condition is a bonus item for multi-disciplinary cooperation, and it is better to meet it, but it is optional if it cannot be met. The second bonus condition is a command that the user wants to add, which can be customized. Generally, it has the lowest priority and can be met or not. If there are special needs, the priority can be increased.

[0046] Specifically, in response to a request to formulate a duct formwork removal plan for the building information model, the terminal obtains the corresponding duct construction plan and preset duct formwork removal evaluation conditions according to the request instruction.

[0047] Step S102: Based on the duct construction plan, obtain multiple candidate duct demolding schemes that meet the basic evaluation conditions for duct demolding.

[0048] Among them, the candidate duct demolition scheme refers to the duct demolition scheme that meets the basic evaluation conditions for duct demolition, but may not meet the evaluation conditions for bonus points in duct demolition. The final target duct demolition scheme is generated from the candidate duct demolition schemes.

[0049] Specifically, the terminal constructs an initial building information model corresponding to the duct construction plan, and then performs demolding processing on the constructed initial building information model according to the basic evaluation conditions for duct demolding, to obtain multiple candidate duct demolding schemes.

[0050] Step S103: Obtain the evaluation results of each of the multiple candidate duct demolding schemes under the duct demolding bonus evaluation conditions.

[0051] The evaluation result refers to the evaluation status of the candidate duct demolding schemes corresponding to the duct demolding bonus evaluation conditions. Its form of expression can be diversified, such as evaluation score, evaluation level, etc.

[0052] Specifically, the terminal analyzes the evaluation criteria for duct demolding bonus points. Based on the analysis results, it identifies the bonus items that meet the evaluation criteria for duct demolding bonus points among multiple candidate duct demolding schemes, and obtains the evaluation level information of the corresponding bonus items for each of the multiple candidate duct demolding schemes as the evaluation result.

[0053] For example, based on the analysis results of the duct demolding bonus evaluation criteria, the terminal identifies three candidate duct demolding schemes that meet the bonus evaluation criteria for duct demolding with 3, 8, and 5 bonus items respectively. Correspondingly, the evaluation level information for each of the three candidate duct demolding schemes for their respective bonus items is obtained as B, A, and B respectively. + The grade is used as the evaluation result.

[0054] Step S104: Based on the evaluation results, select the candidate duct demolding scheme with the best evaluation result from multiple candidate duct demolding schemes, and use it as the target duct demolding scheme corresponding to the duct construction plan.

[0055] Among them, the target duct formwork removal scheme refers to the final duct formwork removal scheme used to assist in the on-site duct construction.

[0056] Specifically, the terminal determines the highest evaluation level among the evaluation results of multiple candidate duct demolding schemes; and identifies the candidate duct demolding scheme corresponding to the highest evaluation level as the candidate duct demolding scheme with the best evaluation result, and as the target duct demolding scheme corresponding to the duct construction plan.

[0057] For example, if the evaluation levels for the corresponding bonus items of the three candidate duct demolding schemes are B, A, and B respectively... + If the evaluation level is A, then the candidate duct demolding scheme corresponding to level A is the candidate duct demolding scheme corresponding to the optimal evaluation result, that is, the target duct demolding scheme corresponding to the duct construction plan.

[0058] The aforementioned duct formwork removal method applied to Building Information Modeling (BIM) involves acquiring a duct construction plan and pre-set duct formwork removal evaluation conditions, including basic duct formwork removal evaluation conditions and bonus evaluation conditions. Based on the duct construction plan, multiple candidate duct formwork removal schemes that meet the basic duct formwork removal evaluation conditions are obtained. The evaluation results of each candidate duct formwork removal scheme under the bonus evaluation conditions are obtained. Based on the evaluation results, the candidate duct formwork removal scheme with the best evaluation result is selected from the multiple candidate duct formwork removal schemes and used as the target duct formwork removal scheme corresponding to the duct construction plan. In this way, by initially screening duct demolding schemes based on the basic evaluation conditions for duct demolding, and then conducting a second screening of the candidate duct demolding schemes based on the bonus evaluation conditions for duct demolding, the requirements of the duct demolding evaluation conditions can be met to the greatest extent. This allows for the development of targeted duct demolding schemes that meet both mandatory conditions and the personalized needs of users, thereby avoiding the need to manually input the values ​​of pipe components and improving the accuracy of duct demolding.

[0059] In one embodiment, step S102 above involves obtaining multiple candidate duct demolding schemes that meet the basic evaluation conditions for duct demolding based on the duct construction plan. Specifically, this includes: extracting duct structure information from the duct construction plan; constructing an initial building information model corresponding to the duct construction plan based on the duct structure information; and performing demolding processing on the initial building information model based on the basic evaluation conditions for duct demolding to obtain multiple candidate duct demolding schemes.

[0060] Among them, duct architecture information refers to the overall duct distribution and location information of the pipeline system used for air transport and distribution.

[0061] Specifically, the terminal extracts the distribution and location information of the ducts from the duct construction plan, summarizes it to form duct structure information, and constructs an initial building information model corresponding to the duct construction plan based on the duct structure information. Based on the standard of the basic evaluation conditions for duct demolding, the initial building information model is demolded to obtain multiple candidate duct demolding schemes that meet the basic evaluation conditions for duct demolding.

[0062] In this embodiment, an initial building information model corresponding to the duct construction plan is constructed based on the extracted duct structure information; then, the initial building information model is processed for demolding according to the basic evaluation conditions for duct demolding, resulting in multiple candidate duct demolding schemes; thus, candidate duct demolding schemes that meet the basic evaluation conditions for duct demolding can be effectively screened, and conditions are provided for further scheme screening.

[0063] In one embodiment, step S103 above involves obtaining the evaluation results of each of the multiple candidate duct demolding schemes under the duct demolding bonus evaluation conditions. Specifically, this includes: identifying the bonus items that meet the duct demolding bonus evaluation conditions among the multiple candidate duct demolding schemes; and obtaining the evaluation score information of the corresponding bonus items of each of the multiple candidate duct demolding schemes as the evaluation result.

[0064] Examples of bonus items that meet the criteria for bonus points in duct demolding evaluation include: checking whether there is maintenance space on the air valve; if there is maintenance space, bonus points are awarded, otherwise no bonus points are awarded.

[0065] Specifically, the terminal identifies and analyzes each candidate duct demolding scheme in turn according to the duct demolding bonus evaluation criteria, obtains the bonus items that meet the duct demolding bonus evaluation criteria for each candidate duct demolding scheme, obtains the evaluation score information of the corresponding bonus items for each candidate duct demolding scheme, and summarizes the evaluation results of multiple candidate duct demolding schemes.

[0066] For example, based on the analysis results of the duct demolding bonus evaluation conditions, the terminal identifies that the three candidate duct demolding schemes each have 3, 8, and 5 bonus items that meet the duct demolding bonus evaluation conditions, respectively. The corresponding evaluation level information for the bonus items of the three candidate duct demolding schemes is obtained as 30 points, 80 points, and 50 points, respectively, as the evaluation result.

[0067] In this embodiment, by obtaining the evaluation results of each of the multiple candidate duct demolding schemes under the duct demolding bonus evaluation conditions, the evaluation result information of each candidate duct demolding scheme can be accurately obtained, and reference information can be provided for further screening of schemes.

[0068] In one embodiment, step S104 above involves selecting the candidate duct demolding scheme with the best evaluation result from multiple candidate duct demolding schemes based on the evaluation results. Specifically, this includes: determining the highest evaluation score information from the evaluation score information of each of the multiple candidate duct demolding schemes; identifying the candidate duct demolding scheme corresponding to the highest evaluation score information as the candidate duct demolding scheme with the best evaluation result.

[0069] Specifically, the terminal compares the evaluation scores of multiple candidate duct demolding schemes to determine the highest evaluation score; it then identifies the candidate duct demolding scheme corresponding to the highest evaluation score as the candidate duct demolding scheme with the best evaluation result.

[0070] For example, if the evaluation level information of the corresponding bonus items for the three candidate duct demolition schemes is 30 points, 80 points and 50 points respectively, then the candidate duct demolition scheme with an evaluation level of 80 points is the candidate duct demolition scheme with the best evaluation result, that is, the target duct demolition scheme corresponding to the duct construction plan.

[0071] In this embodiment, the highest evaluation score is determined from the evaluation score information of each of the multiple candidate duct demolding schemes; the candidate duct demolding scheme corresponding to the highest evaluation score is identified as the candidate duct demolding scheme with the corresponding optimal evaluation result; thus, by referring to the objective indicator of the evaluation score information, the candidate duct demolding scheme with the corresponding optimal evaluation result is accurately identified.

[0072] In one embodiment, the method further includes the following step: when any evaluation condition changes between the basic evaluation condition for duct formwork removal and the bonus evaluation condition for duct formwork removal, the target duct formwork removal scheme corresponding to the duct construction plan is re-determined based on the changed evaluation condition.

[0073] The changed evaluation criteria include: changed basic evaluation criteria for duct demolding, changed bonus evaluation criteria for duct demolding, and simultaneous changes to both basic evaluation criteria and bonus evaluation criteria for duct demolding. For example, the user changed the bonus evaluation criteria for duct demolding from "whether there is maintenance space above the air valve" to "the duct layout should be aesthetically pleasing".

[0074] Specifically, the terminal identifies changes in the evaluation conditions for duct formwork removal. When any change is detected in either the basic evaluation conditions or the bonus evaluation conditions for duct formwork removal, the target duct formwork removal scheme corresponding to the duct construction plan is redefined based on the changed evaluation conditions.

[0075] In this embodiment, when any evaluation condition in the basic evaluation condition or the bonus evaluation condition for duct demolding changes, the target duct demolding scheme corresponding to the duct construction plan is re-determined based on the changed evaluation condition. This allows for flexible acquisition of different target duct demolding schemes according to actual changes, which helps improve the accuracy of duct demolding.

[0076] In one embodiment, the method further includes the following steps: upon receiving feedback information regarding the target duct demolding scheme, recording the feedback information and updating the target duct demolding scheme based on the feedback information; and adjusting the duct structure information in the initial building information model based on the updated target duct demolding scheme to obtain the target building information model.

[0077] The feedback information can be information that is manually reviewed after the target duct demolding plan is found to be incorrect, or information that is imported back after the user feels that there is a better plan and makes modifications.

[0078] Specifically, upon receiving feedback information regarding the target duct demolding scheme, the terminal records and analyzes the feedback information, and modifies and improves the target duct demolding scheme based on the analysis results. Based on the updated target duct demolding scheme, the duct structure information in the initial building information model is adjusted to obtain the target building information model.

[0079] In this embodiment, the target duct demolding scheme is updated based on feedback information, and then the duct structure information in the initial building information model is adjusted based on the updated target duct demolding scheme. This allows for flexible adjustment and improvement of the target duct demolding scheme based on valid information, thereby improving the accuracy of the target building information model.

[0080] In one embodiment, such as Figure 3 As shown, another method for duct demolding applied to Building Information Modeling is provided, which specifically includes the following steps:

[0081] Step S301: Obtain the duct construction plan and the preset duct demolding evaluation conditions; the duct demolding evaluation conditions include the basic evaluation conditions for duct demolding and the bonus evaluation conditions for duct demolding.

[0082] Step S302: Extract duct structure information from the duct construction plan; construct an initial building information model corresponding to the duct construction plan based on the duct structure information; perform demolding processing on the initial building information model according to the duct demolding basic evaluation conditions to obtain multiple candidate duct demolding schemes.

[0083] Step S303: Based on the duct demolding bonus evaluation criteria, identify the bonus items that meet the duct demolding bonus evaluation criteria among multiple candidate duct demolding schemes; obtain the evaluation score information of the corresponding bonus items for each of the multiple candidate duct demolding schemes as the evaluation result.

[0084] Step S304: Among the evaluation score information of multiple candidate duct demolding schemes, determine the highest evaluation score information; identify the candidate duct demolding scheme corresponding to the highest evaluation score information, and use it as the candidate duct demolding scheme with the corresponding optimal evaluation result, and use it as the target duct demolding scheme corresponding to the duct construction plan.

[0085] Step S305: When any evaluation condition changes between the basic evaluation conditions for duct formwork removal and the bonus evaluation conditions for duct formwork removal, the target duct formwork removal scheme corresponding to the duct construction plan is re-determined based on the changed evaluation conditions.

[0086] Step S306: Upon receiving feedback information regarding the target duct demolding scheme, record the feedback information and update the target duct demolding scheme based on the feedback information; adjust the duct structure information in the initial building information model based on the updated target duct demolding scheme to obtain the target building information model.

[0087] The duct demolding method applied to Building Information Modeling in this embodiment performs a preliminary screening of duct demolding schemes based on basic evaluation conditions, and then a secondary screening of the candidate duct demolding schemes based on bonus evaluation conditions. This method can maximize the satisfaction of the duct demolding evaluation conditions and can specifically formulate target duct demolding schemes that meet both mandatory conditions and user-specific needs. This avoids obtaining duct component values ​​through manual input and improves the accuracy of duct demolding.

[0088] To more clearly illustrate the duct demolding method for Building Information Modeling (BIM) provided in this application, a specific embodiment is given below. In one embodiment, this application also provides another duct demolding method for BIM, specifically including the following steps:

[0089] Step 1: Obtain the pre-set duct demolding evaluation conditions, which include basic duct demolding evaluation conditions and bonus evaluation conditions for duct demolding; wherein, the basic duct demolding evaluation conditions consist of mandatory conditions and basic conditions, and the bonus evaluation conditions for duct demolding consist of a first bonus condition and a second bonus condition.

[0090] Step 2: Set the concept of priority, so that the priorities from high to low are mandatory conditions, basic conditions, first bonus conditions and second bonus conditions.

[0091] Step 3: Follow the standards for duct demolding evaluation conditions. First, the mandatory conditions and basic conditions must be met. Second, calculate the comprehensive score of the first and second bonus conditions. Finally, select the highest-scoring scheme and output the target duct demolding scheme.

[0092] Step 4: After the target duct demolding plan is completed, if errors are found during manual review or if the user feels there is a better plan, it can be modified and imported back into the computer. The computer will modify the plan based on the feedback information to obtain the modified plan.

[0093] The beneficial effects of the above embodiments are as follows: (1) It saves a lot of time. The scoring framework mechanism solves the problem that multiple disciplines are difficult to consider comprehensively, and the demolding scheme produced will give priority to standard parts. (2) It improves economic efficiency and solves the problem that the test method is too one-sided. In the scoring framework mechanism, all schemes have been comprehensively considered and calculated. (3) It avoids obtaining the values ​​of pipe components by manual input and improves the accuracy of duct demolding.

[0094] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0095] Based on the same inventive concept, this application also provides a duct demolding device for building information models (BIM) to implement the aforementioned duct demolding method for BIM. The solution provided by this device is similar to the solution described in the above method. Therefore, the specific limitations of one or more embodiments of the duct demolding device for BIM provided below can be found in the limitations of the duct demolding method for BIM described above, and will not be repeated here.

[0096] In one embodiment, such as Figure 4 As shown, a duct demolding device for use in building information modeling is provided, comprising:

[0106] The modules in the aforementioned duct demolding device applied to Building Information Modeling (BIM) can be implemented entirely or partially through software, hardware, or a combination thereof. These modules can be embedded in or independent of the processor in a computer device, or stored in the computer device's memory as software, so that the processor can call and execute the corresponding operations of each module.
