[0045] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0046] like Figure 1 As shown, this invention proposes a simulation calculation method for sound propagation loss based on intelligent agents, including:
[0047] Build a private large model;
[0048] To obtain user needs, based on adaptive terrain feature extraction technology and coding capabilities, the semantic analysis capabilities of the private large model are used to analyze user needs and obtain historical spatiotemporal data and key parameters of the specified sea area.
[0049] Based on historical spatiotemporal data and key parameters of the designated sea area, and using a dynamic model fusion algorithm, the corresponding encapsulated agent is invoked to complete the simulation calculation of acoustic propagation loss; the agent includes one or more physical models for underwater acoustic propagation calculation.
[0050] Obtain simulation calculation results, call the ocean acoustics knowledge base to generate loss suggestions, and visualize the calculation results;
[0051] The working principle of the above technical solution is as follows: In complex seabed topography, the propagation path of sound waves is affected by factors such as seabed topographic undulation, seabed sediment thickness, and seabed substrate type. This application provides a sound propagation loss simulation calculation method based on an intelligent agent, which can provide regional customized sound propagation loss calculation, simulation, and suggestion generation. Through dynamic model fusion algorithm and adaptive terrain feature extraction and encoding technology, the dialogue content or requirements input by the user are given to a large model for semantic analysis. Then, the most suitable agent is called to perform sound propagation loss calculation simulation. The terrain feature extraction technology identifies the elevation changes and complex areas of the terrain. Then, the encoding technology is used to transform these features into key parameters in the sound wave propagation model. The simulation model can more realistically simulate the propagation path and loss of sound waves in the actual environment, improving the accuracy and reliability of the simulation. Finally, the entire calculation simulation process is integrated to build a user-friendly software interface, improving the efficiency of user calculation simulation needs.
[0052] Specifically, this application mainly integrates three aspects: large-scale model with sound propagation loss calculation, marine and underwater acoustic knowledge base construction, and suggestion generation and data query. It also completes a computational simulation model for simulating sound propagation loss, which mainly implements the following three aspects:
[0053] 1. Sound propagation loss calculation: It can perform customized calculation simulations for specific regions based on user requirements. For a specified region, it can call data from the database and select the most suitable agent to calculate the sound propagation loss.
[0054] 2. Construction of marine acoustic knowledge base: This means that it can perform semantic analysis and understanding based on imported historical underwater acoustic data and existing underwater acoustic knowledge, and use it as a knowledge base to achieve simple answers to relevant questions;
[0055] 3. Suggestion generation and data query: This involves integrating the calculated data with the content of the local knowledge base to generate suggestions and perform data analysis. It also includes analyzing dialogues or questions, comparing them with information in the local text and database, using the semantic analysis capabilities of the large model to understand the user's statements, transmitting them to the system, and integrating and outputting relevant results according to the user's requirements.
[0056] To achieve the regional customization requirements for sound propagation loss calculation in the above-mentioned computational simulation model, dynamic model fusion algorithms and adaptive terrain feature extraction and encoding techniques are needed:
[0057] Dynamic model fusion algorithm: After the user input dialogue content or request is given to a large model for semantic analysis, the most suitable agent is called to perform sound propagation loss calculation simulation.
[0058] Adaptive terrain feature extraction and coding technology: This involves identifying terrain elevation changes and complex areas through terrain feature extraction technology, and then using coding technology to transform these features into parameters in the sound wave propagation model. This enables the simulation model to more realistically simulate the propagation path and loss of sound waves in the actual environment, thereby improving the accuracy and reliability of the simulation.
[0059] After optimizing the agent, the main steps for calculating underwater acoustic propagation loss include:
[0060] The physical model of underwater acoustic propagation is constructed. By combining the physical model of underwater acoustic propagation with real-time sound velocity profiles and detailed seabed topographic data, an intelligent model for calculating sound propagation loss is trained.
[0061] Semantic analysis and agent scheduling leverage the semantic analysis capabilities of large models to understand users' actual needs and operations, locate parameters in a specified sea area, find historical data in a specified spatiotemporal domain, call the encapsulated intelligent agent, and select the most suitable physical model for calculation to meet the current requirements.
[0062] Results visualization and suggestion generation: The model output results are visualized by calling graphics libraries such as Matplotlib, and suggestions are generated by integrating the learning capabilities of the large model with the knowledge base of ocean acoustics.
[0063] Furthermore, the main steps for calculating underwater acoustic propagation loss described above can be broken down as follows:
[0064] Based on some acoustic models, several physical models are pre-set and provided for large models to learn and call;
[0065] Analyze the questions or needs raised by users, and use the semantic analysis capabilities of the large model to understand them. If the user lacks sufficient parameters, prompt the user to add parameters (such as selecting the region, query time, etc.).
[0066] Based on parameters such as the area selected by the user and the query time, a physical acoustic model suitable for the current calculation needs is called after comprehensive analysis.
[0067] Based on the model calculation results, corresponding acoustically related result diagrams such as sound propagation loss diagrams and sound field distribution diagrams are generated.
[0068] Finally, based on the images and calculation results, and integrating relevant information from the industry knowledge base, the simulation results are comprehensively analyzed, and a recommendation report is generated, such as... Figure 2 As shown;
[0069] For complex, multi-faceted problems, it is even possible to combine the knowledge from large models with the results of database queries to generate the final answer.
[0070] The beneficial effects of the above technical solution are as follows: Based on a fundamental large-scale model, this solution integrates multiple computational physics models for underwater acoustic propagation and manages the raw data and calculation results, enabling customized simulation and analysis of sound wave propagation loss in different sea areas. This method can efficiently identify and call appropriate computational physics models for underwater acoustic propagation, processing various data types such as measurement point data, text, and files. Through a deep learning large-scale model, the system automatically identifies and extracts key parameters for underwater acoustic propagation calculations, providing high-precision calculation results. Furthermore, the system built based on this method has a unified query interface and real-time monitoring functions, significantly improving user information query efficiency and supporting various application scenarios such as scientific research and engineering design.
