Description

Technical Field

[0001] This invention relates to the field of information technology, and in particular to a nuclear power plant equipment information auxiliary query and location system. Background Technology

[0002] Nuclear power plants are characterized by a wide variety of equipment, small size, complex distribution, and high environmental radiation intensity. On-site equipment inspection work at nuclear power plants faces challenges such as difficulty in confirming locations, unfamiliar routes, and high environmental doses.

[0003] Nuclear power plants typically rely on consulting drawings, forms, or conventional information systems to confirm equipment and on-site information. These methods suffer from low efficiency, fragmented information, and lack of intuitiveness, and can also pose industrial safety risks such as high radiation exposure. With the development of virtual simulation technology, information systems based on 3D models have matured and are widely used in smart cities, collaborative design, and industrial management. These systems offer advantages such as ease of use, intuitive visuals, and convenient maintenance. Therefore, research and product development based on 3D models can be conducted to address the problems currently faced by on-site personnel at nuclear power plants in their daily work, including equipment retrieval, assisted positioning, and information management. Summary of the Invention

[0010] The path navigation module is used for inspection path planning and route demonstration of the 3D model;

[0011] The information display module is used to query and display relevant production information of nuclear power plants in the 3D model. It provides an information query menu, retrieves operation and maintenance work orders, radiation hotspots and radiation zones through external data interfaces and local database queries, and marks the information in the corresponding positions of the 3D model in a graphical way.

[0012] The data maintenance module is a stand-alone client software module used for data modification and maintenance, and supports updating and publishing the modified 3D model and data to the server.

[0016] The global roaming submodule uses the mouse and keyboard to control the viewing angle of the 3D scene, allowing users to view the layout of the 3D model factory and the distribution of equipment from any angle and direction. It also supports quick selection of areas and switching of viewing angles via the navigation map.

[0017] The interactive roaming submodule switches to the third-person perspective of the virtual character, uses the mouse and keyboard to control the virtual character to enter the 3D model factory content, simulates character movement, and views the surrounding environment and facilities from an observation perspective consistent with the real scale.

[0018] The automatic roaming submodule provides a preset automatic roaming route. After the user selects a route in the menu, the roaming will automatically follow the preset route. The automatic roaming supports viewpoint switching and angle adjustment, making it easy to view key areas in the path.

[0019] Preferably, the query and location module includes three sub-modules: regional query, system query, and device query.

[0020] The area query submodule provides a relevant interface menu, allowing users to query spatial area dimensions based on the progressive relationship between units, plants, elevations, and rooms. The 3D model displays and locates the corresponding area model according to the query conditions, and supports quick area selection via navigation map.

Attached Figure Description

[0041] Figure 1 This is a structural diagram of a nuclear power plant equipment information auxiliary query and location system. Detailed Implementation

[0042] To further understand the present invention, embodiments of the present invention are described below in conjunction with examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the present invention, and not for limiting the present invention.

[0043] Embodiments of the present invention disclose a nuclear power plant equipment information auxiliary query and location system, such as... Figure 1 As shown, it includes a 3D model module, a scene loading module, a virtual roaming module, a query and location module, a path navigation module, an information display module, and a data maintenance module.

[0044] The 3D model module utilizes 3DMAX software. The civil engineering of the plant is modeled based on the architectural floor plans, meticulously establishing precise dimensions of the civil structure according to CAD format drawings. Each system's reference piping isometric diagrams, logic diagrams, and layout diagrams are modeled separately, and then integrated with the civil engineering model. Local adjustments and matching are completed. After system civil engineering integration, additional pipe, cable, cable tray, instrument, and through-hole component models are added based on on-site 3D laser scan point cloud data to make the model layout more realistic. Material textures are applied to the model, and, where necessary, normal maps and shadow maps are applied to the civil engineering and large equipment piping to improve model quality. The model scope includes the nuclear island plant civil engineering structure model and the main system equipment piping models. The model's dimensions, plant structure, equipment layout, and object naming are consistent with reality.

[0047] The scene loading module imports the 3D model into the 3D engine, develops a lightweight model algorithm, compresses the imported 3D model data and simplifies the mesh to form a lightweight model suitable for the simulation environment. After processing, the model is published to a high-performance server. When a user's browser needs to access the 3D model, the server first sends a 3D service request to the management service. The management service creates a rendering service and sends the rendering service connection information to the front end. Then, the front-end browser accesses the assigned rendering service and realizes the operation and display of the 3D scene by sending commands and receiving displays. The cloud rendering engine adopts an efficient command transmission mechanism and uses the JavaScript language to encapsulate the underlying functional interfaces, which can be seamlessly integrated into web-based business systems, allowing users to access 3D models and related business functions through a browser.

[0048] The virtual roaming module uses related interactive functions to change the viewing perspective of the 3D model, allowing users to view the layout of the 3D model factory and the distribution of equipment from the desired perspective and route. The module provides roaming interaction methods such as perspective operation or navigation map guidance, and can also select a preset path for automatic roaming. The module includes three sub-modules: global roaming, interactive roaming, and automatic roaming.
