[0001] The present invention relates to the technical field of digital delivery, and in particular to a method and device for digital delivery of a pumped storage power station. Background Art

[0002] In recent years, with the construction practice of large-scale pumped-storage power stations, a full industrial chain development system has basically been formed from planning and design to operation and maintenance, and a large number of engineering documents have been generated at each stage.

[0003] Due to the incompatibility between design software, the data formats generated by different software are incompatible, resulting in the inability to share and transfer data backwards, resulting in data islands. At the same time, during the project handover process, there is a large amount of unstructured data, which is difficult to use, and easily leads to partial data loss or insufficient data utilization. Summary of the invention

[0004] In view of this, the present invention provides a method and device for digital delivery of a pumped-storage power station to solve the problem of low utilization rate of engineering project information of a pumped-storage power station, which causes waste of engineering data resources.

[0005] In a first aspect, the present invention provides a method for digital delivery of a pumped storage power station, the method comprising:

[0006] Obtain the design data of the pumped-storage power station, and build a BIM 3D model of the pumped-storage power station based on the design data of the pumped-storage power station;

[0007] Analyze the BIM 3D model of the pumped storage power station to obtain the engineering object data of the pumped storage power station;

[0008] Define the engineering information database of the pumped storage power station and build the deliverable template based on the engineering information database;

[0009] Use the deliverables template to sort out the project object data of the pumped storage power station and obtain the project deliverables list;

[0010] The project deliverables list is reviewed and the pumped storage power station is digitally delivered based on the review results.

[0011] The present embodiment provides a method for digital delivery of a pumped-storage power station.

[0066] Specifically, for different deliverables, define the work items that need to be checked, configure the content of each inspection item to be checked, and configure the corresponding data quality indicators.

[0070] The present embodiment provides a method for digital delivery of a pumped-storage power station. The method constructs a BIM three-dimensional model of the pumped-storage power station through the design data of the pumped-storage power station, parses the BIM three-dimensional model of the pumped-storage power station, obtains the engineering object data of the pumped-storage power station, and then, based on the engineering object data of the pumped-storage power station, organizes the engineering object data of the pumped-storage power station using a deliverable template to obtain a list of engineering deliverables, thereby realizing the digitization of the delivery process of the pumped-storage power station, making full use of the visualization and transferability characteristics of the BIM three-dimensional model data, improving the delivery efficiency of the pumped-storage power station and the utilization rate of the engineering project information of the pumped-storage power station, reducing delivery information errors, and improving the quality of the delivery data of the pumped-storage power station by reviewing the list of engineering deliverables.

[0071] In this embodiment, a pumped storage power station digital delivery method is provided, which can be used for the above-mentioned electronic equipment. Figure 2is a flow chart of a method for digital delivery of a pumped storage power station according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:

[0072] Step S201, obtain the design data of the pumped storage power station, and construct a BIM three-dimensional model of the pumped storage power station based on the design data of the pumped storage power station. Figure 1 Step S101 of the illustrated embodiment will not be described in detail here.

[0073] Specifically, the above step S201 includes:

[0074] Step S2011, constructing an initial three-dimensional model based on the design data of the pumped-storage power station.

[0075] Specifically, according to the project design requirements and BIM application standards of the pumped-storage power station, an engineering BIM application planning scheme is generated. Combined with the land area information, civil engineering conditions, unified coordinate origin, equipment specification list, equipment appearance and interface data, equipment inspection and maintenance space requirements and other information obtained in the early stage of the project, a preliminary design of the pumped-storage power station is carried out to generate a power station design model (i.e., the initial three-dimensional model).

[0076] Step S2012: perform collision detection on the initial three-dimensional model, and optimize the initial three-dimensional model according to the collision detection result.

[0077] Specifically, the initial three-dimensional model is analyzed, and collision problems in the model are eliminated through collision detection between single or multiple disciplines, and coordination and communication are carried out to deepen the model. Among them, collision detection mainly uses BIM technology to verify the rationality of the distribution design of different professional models. In the actual implementation process, the collision can be divided into hard collision and gap collision. Hard collision refers to the overlap or intersection of the three-dimensional models of the project in space. This kind of situation often occurs between structural beams, air-conditioning pipes and water supply and drainage pipes; gap collision means that the distance between the three-dimensional models of the project is less than the set tolerance, which affects the construction or fails to meet specific requirements. Collision detection is mainly for safety, construction convenience and other considerations. There are minimum spacing requirements between the same profession, and there are also minimum spacing requirements between different professions. It is also necessary to check whether the pipeline equipment blocks the sockets and switches installed on the wall.

[0078] Furthermore, the step of performing collision detection on the initial three-dimensional model includes: reviewing and modifying the initial three-dimensional model; using a physical engine to perform entity collision, extension collision, procedural collision and other detections on the initial three-dimensional model, detecting various types of collisions and outputting the results, and generating a collision detection report; then modifying and optimizing the initial three-dimensional model according to the collision report; repeating the above steps until there is no collision in the initial three-dimensional model.

[0079] Furthermore, the initial three-dimensional model may be subjected to collision detection using an axis-aligned bounding box or a bounding sphere.

[0080] Step S2013, eliminating fragments from the optimized initial three-dimensional model to obtain a BIM three-dimensional model of the pumped-storage power station.

[0081] Specifically, when optimizing the matching and eliminating fragments of the initial 3D model that has passed the collision detection, the useless components, information, viewports, linked files, and imported files in the initial 3D model are preliminarily cleaned up. For more detailed cleaning work, professionals can manually check the model and delete unnecessary elements.

[0082] Furthermore, the internal space of the project is optimized and designed, and virtual simulation roaming is carried out using BIM software such as Revit, Navisworks, SketchUp, etc., to browse and inspect the internal layout of the entire pumped-storage power station, to identify other design risks that were missed in the design process, optimize the BIM design of the entire project, and improve the design quality.

[0083] Step S202: parse the BIM 3D model of the pumped storage power station to obtain the engineering object data of the pumped storage power station. Figure 1 Step S102 of the illustrated embodiment will not be described in detail here.

[0084] Step S203: define the engineering information database of the pumped storage power station and construct a deliverable template based on the engineering information database. Figure 1 Step S103 of the illustrated embodiment will not be described in detail here.

[0085] Step S204: Use the deliverables template to sort out the project data of the pumped storage power station to obtain a project deliverables list. Figure 1 Step S104 of the illustrated embodiment will not be described in detail here.

[0086] Step S205: Review the project delivery list and deliver the pumped storage power station digitally based on the review results. Figure 1 Step S105 of the illustrated embodiment will not be described in detail here.

[0087] The present embodiment provides a method for digital delivery of a pumped-storage power station. An initial three-dimensional model is constructed through the design data of the pumped-storage power station. Collision detection and fragmentation elimination are performed on the initial three-dimensional model, so that the BIM three-dimensional model of the pumped-storage power station is more accurate, thereby ensuring the authenticity and accuracy of the data in the digital delivery process of the pumped-storage power station and reducing the error rate of the delivery information.

[0088] In this embodiment, a pumped storage power station digital delivery method is provided, which can be used for the above-mentioned electronic equipment. Figure 3 is a flow chart of a method for digital delivery of a pumped storage power station according to an embodiment of the present invention. Figure 3 As shown, the process includes the following steps:

[0089] Step S301, obtain the design data of the pumped storage power station, and build a BIM three-dimensional model of the pumped storage power station based on the design data of the pumped storage power station. Figure 2 Step S201 of the illustrated embodiment will not be described in detail here.

[0090] Step S302: parse the BIM three-dimensional model of the pumped-storage power station to obtain engineering object data of the pumped-storage power station.

[0091] Specifically, the above step S302 includes:

[0092] Step S3021, generating a two-dimensional drawing based on the BIM three-dimensional model of the pumped-storage power station.

[0093] Specifically, according to the BIM three-dimensional model of the pumped-storage power station, the plane, system and drawing integrity are checked, and two-dimensional drawings of engineering buildings, structures, equipment, etc. are issued. The specific steps include: adding the line type, line width and color of the drawings in the project information of the pumped-storage power station; establishing a drawing template, adding project information and related parameters; uniformly setting up axis grid elevations and project reference points; adding model construction codes and importing them into the material library, adding the required legends for facade materials; establishing plane drawing requirements applicable to different view templates; adding annotation symbols and annotation styles required for two-dimensional drawings; arranging the plane, elevation, section and large-scale drawings neatly into the drawings and outputting them in PDF or DWG format.

[0094] Step S3022: Perform lightweight analysis on the BIM three-dimensional model of the pumped-storage power station to obtain a lightweight model.

[0095] Specifically, lightweight analysis refers to processing the BIM three-dimensional model of the pumped-storage power station to reduce its storage space and computing resources, thereby improving processing speed and system performance, meeting different scenarios and needs, and optimizing user experience; lightweight analysis of the BIM three-dimensional model of the pumped-storage power station includes: coordinate conversion of the three-dimensional BIM model in a unified format into a three-dimensional coordinate system supported by the system; optimizing the three-dimensional model, reducing and optimizing it through technical means such as triangle simplification, texture optimization, and LOD (Levels of Detail) to obtain an optimized three-dimensional model, namely a lightweight model; among them, lightweight analysis supports BIM format files such as dgn and rvt.

[0096] In some optional implementations, the above step S3022 includes:

[0097] Step a1, coordinate transformation of the BIM three-dimensional model of the pumped storage power station to obtain a three-dimensional coordinate model.

[0098] Specifically, the coordinate transformation of the three-dimensional BIM model in a unified format includes: four-parameter transformation and seven-parameter transformation; among them, the four-parameter transformation is applicable to the transformation between different coordinate systems of the same ellipsoid. By calculating the difference in longitude and latitude of two control points, four transformation parameters (two translation parameters, one rotation parameter, and one scale factor) are obtained to realize the transformation between different coordinate systems; the seven-parameter transformation is applicable to the transformation between different coordinate systems of different ellipsoids (such as WGS84, CGCS2000). By calculating the difference in longitude and latitude of three control points, seven transformation parameters (three translation parameters, three rotation parameters, and one scale factor) are obtained to realize the transformation between different coordinate systems.

[0099] Step a2, optimizing the three-dimensional coordinate model to obtain a lightweight model.

[0100] Specifically, the optimization processing of the three-dimensional coordinate model includes reducing and optimizing the three-dimensional coordinate model by using technical means such as triangle simplification, texture optimization, and LOD.

[0101] Furthermore, triangle simplification is to remove redundant vertices and related triangles generated in the process of model lightweighting according to a certain vertex thinning algorithm, thereby simplifying the triangle mesh.

[0102] Furthermore, texture optimization includes texture compression, parametric texture mapping and texture merging, wherein texture compression uses image compression formats such as JPEG and PNG to compress textures or uses hardware-accelerated texture compression formats supported by GPUs (Graphics Processing Units) such as ETC (Ericsson TextureCompression, a format for texture compression) and ASTC (Adaptive Scalable TextureCompression) to convert high-precision texture images into low-precision texture images; parametric texture mapping divides the generated three-dimensional model surface into several areas and maps them to the texture coordinate system, and selects different parameters for different areas for mapping and optimization; texture merging is to merge multiple small texture images in the generated three-dimensional BIM model into a large texture image, reduce the number of textures, and use the UV coordinate system (two-dimensional image coordinate system) for mapping and rendering.

[0103] Furthermore, LOD technology generates a series of simplified versions (LOD levels) of different precision for the model, and selects the appropriate LOD level for rendering as needed. The three-dimensional lightweight engine automatically generates different levels of LOD based on the imported three-dimensional BIM model according to different screen sizes and the quadtree edge collapse algorithm.

[0104] Step S3023, based on the two-dimensional drawings, use the lightweight model to obtain the pumped storage power station engineering object data.

[0105] Specifically, the two-dimensional drawing is input into the lightweight model to extract the engineering object data of the pumped storage power station; the engineering object data information includes any one or more combinations of engineering object data, engineering object attribute data, document object data and drawing object data.

[0106] Step S303: Define the engineering information database of the pumped storage power station and build a deliverable template based on the engineering information database. Figure 2 Step S203 of the illustrated embodiment will not be described in detail here.

[0107] Step S304: Use the deliverables template to sort out the pumped storage power station project object data to obtain a project deliverables list. Figure 2 Step S204 of the illustrated embodiment will not be described in detail here.

[0108] Step S305: Review the project delivery list and deliver the pumped storage power station digitally based on the review results. Figure 2 Step S205 of the illustrated embodiment will not be described in detail here.

[0109] This embodiment provides a method for digital delivery of a pumped-storage power station. Through BIM forward design, a BIM three-dimensional model of the pumped-storage power station can be constructed based on the design data of the pumped-storage power station, and then a two-dimensional drawing is generated based on the BIM three-dimensional model of the pumped-storage power station, thereby ensuring the authenticity of the data in the engineering drawings, ensuring the high quality of the drawings, greatly shortening the time for drawing review and handover, reducing the time invested by designers in the project, and performing lightweight analysis on the BIM three-dimensional model of the pumped-storage power station to obtain a lightweight model, and using the lightweight model to obtain the engineering object data of the pumped-storage power station, further accelerating the digital delivery speed of the pumped-storage power station while ensuring the reliability of the delivered power station data.
