Description

Technical Field

[0001] The present invention relates to the technical field of computer-aided design, and in particular to a cable laying design method in a substation based on BIM technology. Background Art

[0002] The traditional design method used by the power industry in the design process of conventional cable laying requires designers to first plan the cable path, try to draw horizontal straight cable segments to verify whether the bending radius of the cable laying can be met, and verify the feasibility and rationality of the planned path. If there is a collision problem, re-planning and modification are required.

[0003] When using BIM technology for cable laying design, designers need to plan each cable path, draw the three-dimensional curve of the cable path, and perform three-dimensional curve lofting to achieve cable entity modeling.

[0004] The traditional design method has problems such as inconsistent design, rough cable path planning, no visualization of cable path planning, and unintuitive design results. At the current stage, when BIM technology is used for design, it is necessary to plan each cable path separately and perform physical modeling separately, which makes the cable laying design operation difficult and cumbersome, and the design efficiency is low.

[0005] Therefore, how to solve the problem of separately planning and modeling individual cable paths during cable laying design using BIM technology in the prior art has become a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] In view of the above-mentioned defects of the prior art, the present invention provides a cable laying design method in a substation based on BIM technology, and its purpose is to solve the problem that in the prior art, during the cable laying design process using BIM technology, separate planning and modeling of separate cable paths are required.

[0007] To achieve the above object, the present invention discloses a cable laying design method in a substation based on BIM technology, and adopts BIM software Revit software to perform the following steps:

[0008] Step 1: Stent planning;

[0009] Step 2: Cable arrangement;

[0010] Step 3: Device connection and entry and exit settings;

[0011] Step 4: Standardize settings.

[0012] Preferably, the bracket planning includes cable bracket parameter settings and bracket path parameter settings. According to the cable bracket parameters and bracket path parameters input by the designer, the design of the cable bracket path planning is realized, and cable brackets are generated in batches. The cables are batch modeled by fitting the three-dimensional curve of the cable path points.

[0013] Preferably, the cable arrangement includes a path support selection function, a cable selection function, an automatic / manual cable arrangement function and a cable generation function;

[0014] The path bracket selection function plans the cables passing through the brackets selected by the designer in batches according to the brackets selected by the designer in batches;

[0015] The cable selection function automatically retrieves the corresponding voltage level and diameter parameters from the database according to the cable model set by the designer. When the cable model set by the designer is not in the library, it is manually added by the designer;

[0016] The automatic / manual cable arrangement function has automatic and manual modes to realize batch arrangement of cables;

[0017] The cable generation function realizes cable path generation according to the inputs of the designer in the path bracket selection function, the cable selection function and the automatic / manual cable arrangement function.

[0018] More preferably, when using the automatic / manual cable arrangement function, the designer first arranges the cables in batches using the automatic method, and then adjusts individual cables by the manual method to optimize the effect of the batch arrangement of cables.

[0019] Preferably, in step 3, the cable layer integrated layout module realizes the connection function from the cable path to the device or to the opening. The designer selects the planned cable path and connects the cable corresponding to the path to any desired device or opening.

[0020] More preferably, in step 4, the cable layer integrated layout module corresponds to the standardization of design elements, and the design elements including the generated brackets and cables are standardized according to the standards, so that the finished design meets the delivery standards.

[0021] Beneficial effects of the present invention:

[0022] The application of the present invention can solve the problem in the prior art that in the process of cable laying design using BIM technology, separate cable paths need to be planned and modeled separately.

[0035] Example

[0036] like Figures 1 to 11 As shown in the figure, the cable laying design method in the substation based on BIM technology uses the BIM software Revit to perform the following steps:

[0037] Step 1: Stent planning;

[0038] Step 2: Cable arrangement;

[0039] Step 3: Device connection and entry and exit settings;

[0040] Step 4: Standardize settings.

[0041] The use of this patented technology in the commonly used BIM software Revit can realize the batch planning, modeling and design of cables on the same plane of the substation. The design effect satisfies the visualization and accuracy of the design results. At the same time, there is no need for manual modeling, which greatly reduces the difficulty of operating BIM technology in the substation design process and improves the design efficiency.

[0042] In some embodiments, the bracket planning includes cable bracket parameter settings and bracket path parameter settings. According to the cable bracket parameters and bracket path parameters input by the designer, the design of the cable bracket path is planned, and cable brackets are generated in batches. The cables are batch modeled by fitting three-dimensional curves of the cable path points.

[0043] In actual applications, bracket planning includes two major functions: cable bracket parameter setting and bracket path parameter setting. Designers first plan the cable bracket parameters, then set the bracket path parameters, and implement the planning of the cable bracket path. The bracket planning function will generate cable brackets in batches based on the bracket parameters and path parameters set in the layout.

[0044] The present invention combines the advantages of traditional cable laying design methods and BIM design methods, and realizes batch planning of cable paths accurately to hole positions in a BIM environment, and realizes batch modeling of cables by fitting three-dimensional curves of cable path points.

[0045] In some embodiments, the cable arrangement includes a path support selection function, a cable selection function, an automatic / manual cable arrangement function, and a cable generation function;

[0046] The path bracket selection function selects brackets in batches according to the designer, and the planning designer selects the cables passing through the brackets in batches;

[0047] The cable selection function automatically retrieves the corresponding voltage level and diameter parameters from the database according to the cable model set by the designer. If the cable model set by the designer is not in the library, it will be added manually by the designer.

[0048] Automatic / manual cable arrangement function has automatic and manual modes to realize batch arrangement of cables;

[0049] In actual applications, the order of bulk cable arrangement is to first plan the cable laying path - generate cable racks based on this path - and then arrange the cables in batches through the racks.

[0050] The cable generation function generates cable paths based on the designer's input in the path bracket selection function, cable selection function and automatic / manual cable arrangement function.

[0051] In some embodiments, when using the automatic / manual cable routing function, the designer first routes cables in batches automatically, and then manually adjusts individual cables to optimize the effect of the batch routing.

[0052] In some embodiments, in step 3, the cable layer integrated layout module realizes the function of connecting the cable path to the device or to the opening. According to the designer's selection of the planned cable path, the cable corresponding to the path is connected to any desired device or opening.

[0053] In some embodiments, in step 4, the cable layer integrated layout module corresponds to the standardization of design elements, and standardizes the design elements including the generated brackets and cables according to the standards, so that the finished design meets the delivery standards.

[0054] In actual applications, the cable layer integrated layout module provides the function of standardizing corresponding design elements. By using this function, designers can standardize the design elements such as brackets and cables generated by each functional module according to the "Relevant Requirements in the State Grid Shanghai Digital Delivery Standard", so that the finished design meets the delivery standards and improves the design quality.

[0055] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
