Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated construction, and more specifically, to an intelligent prefabricated construction design method and system. Background Art

[0002] One of the most critical steps in prefabricated construction is the assembly drawing splitting and output. Traditionally, designers manually split pipe segments within the model and added connecting flanges. They then sequentially divided the split components into individual component groups, annotated the component groups for machining accuracy, and then exported 2D machining drawings. A single prefabricated computer room typically consists of over 200 components. Due to the large number of components and the heavy workload of repetitive operations, the design splitting and outputting process is inefficient. The ability to efficiently and effectively split and output models built to 1:1 precision, thereby improving design and output capabilities and reducing design costs, is of far-reaching significance in the field of prefabricated construction. Summary of the Invention

[0003] The present invention aims to solve the technical problems existing in the prior art and provides an intelligent prefabricated construction design method and system.

[0004] According to a first aspect of the present invention, there is provided an intelligent prefabricated construction design method, comprising the following steps:

[0005] S1, identifying components of the building information model, splitting the building information model into multiple components according to preset logical judgment criteria during the identification process, and breaking and setting breakpoints at the split locations;

[0006] S2: number the components after splitting, obtain the views of each component and mark them accordingly, and finally generate a two-dimensional processing drawing.

[0007] Optionally, the building information model includes pipes, connectors, elbows, tees and valve components.

[0008] Optionally, the preset logic judgment criteria in S1 specifically include: selecting a section of pipeline, and successively determining whether it is a straight pipe, whether there is an elbow, whether it contains a tee, and whether it contains a valve component.

[0009] Optionally, the preset logic judgment criteria in S1 specifically include: determining once whether it is a straight pipe segment, and if so, breaking it into 8-meter segments at the end and adding a flange;

[0010] If the length of the straight pipe is less than 8 meters, a second determination is made to determine whether there is an elbow. If so, it is disconnected at 0.5 meters on one side of the elbow and a flange is added; if there is no elbow, a third determination is made to determine whether there is a tee. If so, it is disconnected at 0.5 meters on the tee branch and a flange is added; if there is no tee, a fourth determination is made to determine whether there is a valve component. If so, the flange on one side of the valve is used as the boundary as a section.

[0011] Optionally, when performing a secondary determination on whether there is an elbow, if there is, and there is a second elbow within 0.6 meters on both sides of the elbow, the second elbow is disconnected at 0.5 meters outside and a flange is added.

[0012] Optionally, when there is no elbow, three determinations are made to determine whether a tee exists. If so, and there are tees within 2 meters on both sides of the tee, the two tees are disconnected 0.5 meters outside and flanges are added.

[0013] Optionally, when there is no tee, four determinations are made as to whether a valve component exists. If so, and there is a second valve within 0.6 meters on both sides of the valve component, the second valve is used as the boundary, and the inner and outer sides are respectively regarded as a section.

[0014] Optionally, the obtaining of views of each component and the corresponding marking in S2 specifically includes: executing a first program command on the component with the identification number to generate a top view, a front view, a left view, and a three-dimensional view;

[0015] By identifiability of the component, run the second program command for each view in turn:

[0016] S21, starting from the starting end and identifying in sequence, marking each component once;

[0017] S22, label each identified component separately;

[0018] S23, where the elbow is marked with the center, and the valve components are marked with the flanges at both ends;

[0019] S24, use family tags to mark the names and sizes of each component.

[0020] According to a second aspect of the present invention, a system for implementing an intelligent prefabricated construction method is provided, comprising:

[0021] A splitting module is used to identify components of the building information model. By using preset logical judgment criteria, the building information model is split into multiple components during the identification process, and the components are disconnected and breakpoints are set at the split points.

[0022] The drawing output module is used to number the components after the splitting is completed, obtain the views of each component and mark them accordingly, and finally generate a two-dimensional processing drawing.

[0023] Beneficial Effects: The present invention provides an intelligent prefabricated construction design method and system, wherein the method includes S1, identifying components of a building information model, and using preset logical judgment criteria, splitting the building information model into multiple components during the identification process, breaking and setting breakpoints at the split locations; S2, numbering the components after splitting, obtaining views of each component and annotating them accordingly, and finally generating a two-dimensional processing drawing. This solution only requires the development of a simple instruction logic program to perform repetitive operations of intelligent splitting and drawing, reducing the design workload. It can effectively improve the efficiency of the design part of the prefabricated construction process, thereby improving design and drawing capabilities and reducing design costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 2 This is a flow chart of the drawing process of an intelligent prefabricated construction design method provided by the present invention. DETAILED DESCRIPTION

[0026] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0027] like Figure 1 and Figure 2 As shown, an intelligent prefabricated construction design method provided by the present invention includes the following steps:

[0028] S1, identifying components of the building information model, splitting the building information model into multiple components according to preset logical judgment criteria during the identification process, and breaking and setting breakpoints at the split locations;

[0029] S2: number the components after splitting, obtain the views of each component and mark them accordingly, and finally generate a two-dimensional processing drawing.

[0030] Technical feasibility analysis and experimental verification of the scheme:

[0031] (1) The process of establishing a BIM model is to combine pipes, connectors, elbows, tees, valve components, etc., that is, the software itself can identify the relevant components, and by adding relevant logical judgments, the entire model can be split.

[0032] (2) After splitting, the entire model is formed into several component groups. By adding auxiliary logic, the top view, front view, left view, and three-dimensional view are generated in the exported two-dimensional drawings, and the views are annotated in sequence. Since the software itself can identify the relevant components, only the annotation logic needs to be set to achieve annotation that meets the processing accuracy. Based on the above analysis, this technology is feasible.

[0033] The specific working principle is as follows:

[0034] (1) Building Information Model, hereinafter referred to as model, is formed by combining pipes, connectors, elbows, tees, valves, etc. The BIM software itself can identify the corresponding components, so the identification process is used to add logical judgment to split. For example, if a certain section of pipe is selected, the logical judgment is whether it is a straight pipe section. If it is, it is divided into 8-meter sections and a flange is added at the end. If not, a second judgment is made to see whether there is an elbow. If so, a flange is added 0.5 meters to the right of the elbow. If there is no elbow, a third judgment is made to see whether there is a tee. If so, the tee branch is disconnected and a flange is added 0.5 meters away. If there is no tee, a fourth judgment is made to see whether there is a valve component. If so, the flange on one side of the valve is used as the boundary as a section. And so on, the model is split.

[0035] A further solution involves performing a second check to determine if an elbow exists. If so, and there is a second elbow within 0.6 meters on either side of the elbow, a flange is added 0.5 meters outside the second elbow. If there is no elbow, a third check is performed to determine if a tee exists. If so, and there is a tee within 2 meters on either side of the tee, a flange is added 0.5 meters outside each of the two tees. If there is no tee, a fourth check is performed to determine if a valve component exists. If so, and there is a second valve within 0.6 meters on either side of the valve component, the second valve is used as the boundary, with the inner and outer sides each being considered as a section.

[0036] (2) After the split is completed, identify the breakpoints of the split, run the numbering program for the components at each breakpoint in turn, and obtain multiple numbered components. Then, run the program command on the identified numbered components to generate the top view, front view, left view, and three-dimensional view. Based on the identifiability of the components, run the program command on each view in turn:

[0037] 1. Take the starting end as the endpoint and identify them in sequence, marking each component once;

[0038] 2. Label each identified component separately;

[0039] 3. The center of the elbow is marked as the mark point, and the flanges at both ends of the valve parts are marked as the mark points;

[0040] 4. Use family tags to mark the names and sizes of each component, and finally run the export command to generate two-dimensional processing drawings.

[0041] This solution only requires the development of a simple instruction logic program to perform repetitive operations such as intelligent splitting and drawing, reducing the design workload. It can effectively improve the efficiency of the design part of the prefabricated construction process, thereby improving design and drawing capabilities and reducing design costs.
