[0060] The technical solution adopted in this embodiment is that the underwater hybrid simulation experiment system adopts a hierarchical design, including a business application layer, a business support layer, and a basic software layer. The business support layer and the business application layer are connected through a platform control agent, and each layer adopts a modular design to reduce coupling and improve scalability. Based on the business support layer, a graphical human-computer interaction environment is directly provided to users; the business support layer mainly includes a simulation deduction platform and a situation rendering engine supported by two data, a simulation model library and a visualization resource library, and provides a platform control agent to respond to external control instructions and data interaction; the basic software support layer includes the basic system library and the network communication library and database management system support used within the system. The business application layer includes modules such as scenario editing, data playback, comprehensive situation display, hybrid experiment simulation, and performance evaluation for specific applications.

[0061] The business application layer is used to perform pure digital simulation or hybrid simulation on the business according to the business needs of the user, store the data of the deduction process, and display the results of the deduction; the business application layer is customized according to the business needs of the user, provides a graphical human-computer interaction interface, calls the functions of the business support layer by binding the platform control adapter, and completes the assumption editing module, data return module, comprehensive situation display module, hybrid experiment simulation module and effectiveness evaluation module;

[0064] The pure digital simulation mode is an underwater hybrid simulation experiment simulation system that supports users to configure simulation scenarios, perform underwater simulation deductions, and record and playback data through the system without the need for physical equipment for testing.

[0065] The hybrid simulation mode is that the underwater hybrid simulation experiment simulation system supports the access of physical equipment. Therefore, a hybrid simulation module is constructed to complete the interaction with the physical equipment by constructing a shadow model. Among them, when the participating physical equipment is connected, the flag of the shadow model is set to valid; when there is no participating physical equipment, the flag of the shadow model is set to invalid. When the participating physical equipment is connected, the system replaces the simulation calculation by receiving the experimental data of the participating physical equipment during the simulation process. At the same time, the digital simulation method is used to simulate the test equipment, and the experimental data of the participating equipment is combined for simulation deduction to generate incentive data to provide the required situation data for the participating equipment.

It provides the import of models loaded in the situation interface and the addition of content such as color, lighting, and shadows. It supports the rendering and visualization of special effects such as wind, rain, thunder, lightning, and snow.

[0072] The platform control adapter is a customized development for the technical support of the project system in terms of network communication, simulation operation control, data storage, etc., to achieve the bridge between the business support layer and the business layer module. The platform control adapter mainly includes three parts: data storage access adapter, data storage communication adapter, and operation control response adapter.

[0073] The basic software layer is used to develop various business demand function modules on the business support layer. The basic software support layer is the bottom-level technical support of the entire software architecture, which has nothing to do with the business functions of this system. The business support layer is mainly developed and implemented based on this basis.

[0074] The basic software layer includes an OSG three-dimensional scene module, a QT interface library, a network communication library, a database management system and a supporting system library; the OSG three-dimensional scene module is used for simulation and visualization, and provides scene management and graphics rendering optimization for the development of graphics and images; the QT interface library is used for interface development and management, and provides a variety of templates to support rapid development; the network communication library is used for network communication between various modules of the system, integrating and encapsulating commonly used communication methods; the database management system is used for the management of various types of data generated by the system, including the addition, deletion, modification and query of data; the supporting system library is used to support the software to run on the operating system and provide the necessary environment for the normal operation of the software.

Figure 2 As shown, the simulation deduction platform obtains the assumption data and the basic parameter information of the platform related to the assumption from the database.
