[0034] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] In a preferred embodiment, reference Figure 1 The implementation and verification MOCK-UP method based on three-dimensional virtual reality in this embodiment includes the following steps:

[0036] S1. Obtain external scanning information by scanning the physical cabinet with a laser scanner, generate a three-dimensional real cabinet based on the external scanning information, establish a three-dimensional virtual model based on the internal structural drawings of the cabinet, and build a three-dimensional simulation cabinet from the three-dimensional real cabinet and the three-dimensional virtual model.

[0037] Specifically, to ensure that the established 3D model is consistent with the real rack, this embodiment uses a laser scanner to scan the exterior of the physical rack to obtain external scan information, and generates a 3D real rack based on the external scan information. This 3D real rack is consistent with the real rack in shape and size, thereby ensuring the reliability of subsequent simulation verification. For the internal structure of the rack, internal structural drawings are obtained, and a 3D virtual model is created using 3D modeling software based on these drawings. The virtual internal structure corresponding to the 3D virtual model is then placed inside the 3D real rack to create a 3D simulation rack.

[0038] S2. Based on the component information knowledge base of the cabinet, establish a three-dimensional simulation model of the three-dimensional components inside the cabinet. Based on the terminal information knowledge base of the cabinet, establish a three-dimensional terminal model on the three-dimensional component model. Based on the cable information knowledge base of the cabinet, establish a three-dimensional cable model.

[0039] Specifically, the 3D simulation cabinet already includes the cabinet shell and internal structure. Further refinement is needed to include the internal components and cables to achieve complete 3D virtualization of the real cabinet. First, a component information knowledge base is acquired, containing relevant information about the internal components, such as model number, structure, and interfaces. A 3D component model is then built based on this knowledge base. Second, a terminal information knowledge base is acquired, containing information about each port of the components. A 3D terminal model is then built on top of the 3D component model. Third, a cable information knowledge base is acquired, containing information about all types of cables used in the cabinet, including power cables and signal transmission lines. A 3D cable model is then built based on this knowledge base.

[0040] S3. Use 3D simulation cabinet, 3D component model, 3D terminal model and 3D cable model to dynamically simulate the disassembly and assembly of cabinet and cables.

[0041] Specifically, after establishing 3D simulation models of the cabinet, components, terminals, and cables, these models are combined into a unified 3D system, achieving complete 3D simulation of the cabinet. Utilizing the detachable and animated features of 3D models, the cabinet, component, terminal, and cable models are used to dynamically simulate cabinet assembly and disassembly, as well as cable assembly and disassembly. In other words, staff can directly operate these models to practice cabinet assembly and disassembly, making training more comprehensive and intuitive, significantly enhancing the quality of staff training.

[0042] This embodiment uses virtual reality technology to simulate the cabinet, making the construction drills more realistic and accurate, and improving the training quality of construction personnel.

[0043] refer to Figure 2 Some embodiments of the MOCK-UP method for implementation and verification based on three-dimensional virtual reality also include the following steps:

[0044] S4. Obtain the rack code and cable termination data. Generate corresponding graphic codes based on the cable codes in the rack code and cable termination data. Set the construction animation corresponding to each graphic code and store the construction animation to the server. The construction animation is simulated by a 3D simulation rack, 3D component model, 3D terminal model and 3D cable model. The graphic codes are used to fix the physical cables and physical rack.

[0045] Specifically, during the rack assembly / disassembly process, a large number of cables need to be disconnected and reconnected. Existing technology relies on matching rack codes on the rack with cable codes on the cables, referring to paper termination documentation. This process doesn't allow staff to visually observe the disconnection / reconnection process, hindering training. This embodiment uses 3D simulation models of the rack, components, terminals, and cables to generate construction animations for each interface and cable group within each rack. These animations include disconnection and connection processes, allowing staff to intuitively understand the installation process. Furthermore, rack codes and cable termination data are acquired, and corresponding graphic codes are generated based on the cable codes. These graphic codes are printed and affixed to the physical cables and racks. Additionally, construction animations are set for each graphic code, i.e., construction animations corresponding to rack codes and cable codes are created. These animations, along with the correspondence between graphic codes and construction animations, are stored on a server. Optionally, the graphic codes can be barcodes or QR codes.

[0046] S5: The smart mobile terminal scans the graphic code to obtain and display the construction animation corresponding to the graphic code.

[0047] Specifically, during construction, when cables need to be spliced ​​or disconnected, workers can use a smart mobile terminal to scan a graphic code. After parsing the graphic code, the smart mobile terminal retrieves the corresponding construction animation from the server. The construction animation is then displayed on the smart mobile terminal, allowing workers to directly view it and follow the instructions to splice or disconnect cables. Alternatively, smartphones and tablets can be used as smart mobile terminals, which connect to the server via a wireless network, such as WiFi or cellular network.

[0048] This embodiment produces construction videos for each set of interfaces and cables. Staff can scan the graphic code to watch the construction animation, which can improve the accuracy and efficiency of construction.

[0049] In some embodiments of the MOCK-UP method based on 3D virtual reality for implementation and verification, considering that cabinet construction-related data in nuclear power plants is mostly stored in the system in the form of image files or PDF files, OCR text recognition technology can be used to recognize the cabinet codes and cable termination data in the image files and / or PDF files when obtaining cabinet codes and cable termination data. This embodiment uses OCR text recognition technology to recognize cabinet codes and cable termination data in image files and PDF files, achieving automatic data extraction and significantly reducing labor costs.

[0050] In some embodiments of the MOCK-UP method based on 3D virtual reality for implementation and verification, risks discovered during construction drills can be recorded, generating risk warning information; or risk warning information can be set based on past construction experience, with each graphic code corresponding to a construction animation and risk warning information, which are then stored on a server. Correspondingly, during construction, when cables need to be spliced ​​or disconnected, workers can use a smart mobile terminal to scan the graphic code. After parsing the graphic code, the smart mobile terminal retrieves the corresponding construction animation and risk warning information from the server. The construction animation and risk warning information are displayed on the smart mobile terminal, allowing workers to directly view them and follow the instructions in the animation to splice or disconnect cables, while also paying attention to risk avoidance, thus improving construction safety and quality. This embodiment can simultaneously provide construction animation and risk warning information through graphic codes, guiding workers during construction and helping them avoid risks in advance, thereby improving construction safety and quality.

[0051] In some embodiments of the MOCK-UP method for implementation and verification based on 3D virtual reality, reference is made to... Figure 3 After scanning the graphic code on a smart mobile terminal, the following steps are also included:

[0052] S6. The intelligent mobile terminal uploads the rack code and cable code corresponding to the graphic code to the server in real time. The server records the rack code and cable code in real time and obtains the real-time construction progress based on the completed rack code and cable code.

[0053] Specifically, to monitor real-time construction progress, after scanning the graphic code on a smart mobile terminal, a construction animation and risk warning information are displayed on the terminal. If workers complete the construction according to the animation, the smart mobile terminal uploads the corresponding rack and cable codes to the server in real time. The server records the rack and cable codes in real time. Since the total number of rack and cable codes is known, the real-time construction progress can be obtained based on the completed rack and cable codes. During construction, the project schedule and on-site wiring quality can be dynamically and precisely controlled based on the percentage of wiring completed each day.

[0054] This embodiment enables staff to monitor the construction progress in real time, achieving refined construction.

[0055] refer to Figure 4 Some embodiments of the MOCK-UP method for implementation and verification based on three-dimensional virtual reality also include the following steps:

[0056] S11. Obtain the building scanning information by scanning the actual nuclear power plant building with a laser scanner, and build a three-dimensional building model based on the building scanning information.

[0057] Specifically, cabinet replacement also includes cabinet relocation, which involves moving the existing cabinet out of the nuclear power plant building and moving the new cabinet into the building. To simulate the cabinet relocation in and out of the building using 3D simulation, a 3D model of the nuclear power plant building is needed. In this embodiment, a laser scanner is used to scan the actual nuclear power plant building to obtain the scan information, and a 3D model of the building is then created based on this information. Because laser scanners have high precision, the 3D model of the building created from the scan information is essentially consistent with the actual nuclear power plant building and can accurately reflect the real building information.

[0058] S12. Select the rack migration route in the 3D factory model, and use the 3D simulation rack to move along the rack migration route in the 3D factory model to simulate the rack migration process.

[0059] Specifically, after establishing a 3D factory model, a rack migration route is selected based on the dimensions of the 3D factory model and the dimensions of the 3D simulation rack, or based on experience. Optionally, one or more rack migration routes can be selected. After selecting a rack migration route in the 3D factory model, the 3D simulation rack moves along the rack migration route in the 3D factory model to simulate the rack migration process. In this embodiment, after selecting a rack migration route, the 3D simulation rack will automatically move according to the rack migration route, that is, automatically move from one end of the rack migration route to the other end, to simulate the rack migration process and verify whether the selected rack migration paths meet the requirements.

[0060] This embodiment establishes a three-dimensional plant model consistent with the actual nuclear power plant building, and realizes the migration route simulation of the three-dimensional simulation cabinet to verify the cabinet migration path in advance and ensure that subsequent construction can proceed smoothly.

[0061] refer to Figure 5 Some embodiments of the MOCK-UP method for implementation and verification based on three-dimensional virtual reality also include the following steps:

[0062] S13. During the simulated cabinet migration process, monitor the distance between the edge of the 3D simulation cabinet and the 3D factory model. When the distance is less than the preset distance, generate construction warning information and save the construction warning information and the location of the risk point to the cabinet migration route of the 3D factory model.

[0063] Specifically, after selecting a rack migration route in the 3D factory model, a 3D simulation rack moves along this route to simulate the rack migration process. During the simulated migration, the distance between the edge of the 3D simulation rack and the 3D factory model is monitored to determine if this distance is less than a preset distance. This preset distance is a safe distance to avoid collisions between the rack and the factory or other equipment. If the distance is greater than the preset distance, it means the rack will not collide with the factory or other equipment during the movement. If the distance is less than the preset distance, it indicates a risk of collision, so a construction warning is generated when the distance is less than the preset distance. This warning information and the location of the risk point are saved to the rack migration route in the 3D factory model. It is understandable that, since the dimensions of the 3D factory model and the 3D simulation cabinet are known, during the migration of the simulated cabinet, the distance between the edge of the 3D simulation cabinet and the 3D factory model is automatically monitored. When the distance is less than the preset distance, a construction warning message is automatically generated, and the construction warning message and the location of the risk point are automatically saved to the cabinet migration route of the 3D factory model. This process is fully automated, realizing the automation of the simulated cabinet migration.

[0064] This embodiment automatically identifies and records risk points during the simulated cabinet migration process, thus automating the simulated cabinet migration. It also saves the location of risk points, which can guide staff during training and construction, improving training effectiveness and reducing construction risks.

[0065] refer to Figure 6 Some embodiments of the MOCK-UP method for implementation and verification based on three-dimensional virtual reality also include the following steps:

[0066] S14. The actual rack movement position is synchronized to the 3D factory model in real time, and construction warning information is displayed when construction reaches a risk point. Specifically, during construction, the actual rack movement position is synchronized to the 3D factory model in real time. The model checks if there are any saved risk points at the current location of the actual rack. If so, a construction warning message is displayed when construction reaches a risk point, reminding workers to pay extra attention to avoid collisions. This embodiment can display risk point locations during actual construction, prompting workers to pay extra attention, which can effectively reduce construction risks.
