Furthermore, traditional methods fail to provide an immersive training experience. Operators often struggle to respond to emergencies in actual operations due to a lack of realism, further reducing the practicality and safety of training. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the present invention more apparent, the following will provide a clear and complete description of the technical solutions of the present invention in conjunction with the accompanying drawings. It should be understood that the description is only a portion of the present invention, not all of it. The components of the present invention generally described and illustrated in the drawings herein may be arranged and designed in a variety of different configurations.

[0045] like Figure 1 As shown, the present invention provides one embodiment: a method for constructing and integrating a virtual simulation system of a hydropower station, the method comprising the steps of:

[0046] Draw simulation system algorithm icons based on Microsoft Visio tools and generate EMF format files;

[0047] Define the simulation system algorithm properties based on the PIcon tool and generate TAB format files;

[0048] Write simulation system algorithms based on Compaq Visual Fortran tools and compile them into DLL dynamic library files;

[0049] Combine EMF format files, TAB format files, and DLL dynamic library files, and use the algorithm model of the algorithm library to build system models such as the hydropower station's oil, water, and gas system, main electrical wiring, excitation system, and GIS switch station. Through algorithm parameter debugging, the corresponding displayed values ​​are made to conform to the actual values ​​on site at the power station.

[0050] After completing the construction of the simulation system, the communication program SIM2HMI and the simulation data transmission program Modsvr are used to enable IO interaction between the simulation project and the VR project version;

[0051] The completed simulation system is embedded into the VR device integrated with the hydropower station VR scene to complete the configuration.

[0052] In this embodiment, the specific steps are as follows: Step 1: Use Microsoft Visio to draw the simulation system algorithm icon and save it in .emf format. Step 2: Use the PIcon tool included with the simulation platform to define the simulation system algorithm properties and save them in tab format. Step 3: Use Compaq Visual Fortran software to write the simulation system algorithm and compile it into a .dll dynamic library file. Step 4: Build a simulation system environment identical to a real DCS system.

[0053] Start the simulation project, open the trainer model system, start the communication program SIM2HMI, and the simulation data transmission program Modsvr, and keep the simulation background stable and normal during the data transmission process;

[0054] Open the Steam platform, start SteamVR, and turn on the corresponding controllers and helmets to establish a wireless connection with the locator;

[0055] Open the simulated VR version of the 3D project on the PC. After starting it, you can see the corresponding 3D scene in the VR helmet. At the same time, you can see the virtualized left and right gloves of the corresponding left and right handles in your field of view.

[0056] like Figure 2 As shown, in step 1 of this embodiment, the simulation system algorithm icon is drawn based on the Microsoft Visio tool, and an EMF format file is generated, which is specifically:

[0057] Start Microsoft Visio, select the built-in basic block diagram template, and create a blank VSD file;

[0058] Draw an icon for the blank VSD file according to the preset standard, and define the algorithm name and input and output pins on the icon;

[0059] Save the completed icon as an EMF format file and output it.

[0060] In practice, the steps for creating a simulation system algorithm icon are as follows: Step 1.1: Launch Microsoft Visio, select the Basic Block Diagram template, and create a blank VSD file. Step 1.2: Refer to the DCS manufacturer's "Control Algorithm Reference Manual" or "Function Code Manual" and use Microsoft Visio to draw an identical icon. Define the algorithm name and input and output pins on the icon. Step 1.3: Save the drawn icon as an enhanced metafile (.emf format).

[0061] In step 2 of this embodiment, the simulation system algorithm attributes are defined based on the PIcon tool, and a TAB format file is generated, which is specifically:

[0062] Create a new TAB file using the PIcon tool;

[0063] Add the algorithm to the TAB file, including the algorithm name, EMF format file name, input, output and coefficient order;

[0064] Output TAB format file.

[0065] In practice, the steps for creating a tab file are as follows: Step 2.1: Use the platform's built-in PIcon.exe tool to create a new tab file. Step 2.2: Add the algorithm to the tab file. The algorithm file includes the algorithm name, the icon name corresponding to the algorithm name, the input, output, coefficient order, etc.

[0066] In step 3 of this embodiment, the simulation system algorithm is written based on the Compaq Visual Fortran tool and compiled into a DLL dynamic library file, which is specifically:

[0067] Create a new workspace using Compaq Visual Fortran;

[0068] Create a dynamic link library project in the workspace;

[0069] Creating and compiling a new algorithm file in a dynamic link library project, wherein the algorithm file corresponds to the algorithm properties of the simulation system;

[0070] Verify whether the algorithm file compilation is correct. If correct, encapsulate all algorithm files in the dynamic link library project to form a DLL dynamic library file.

[0071] In practice, the steps for generating a DLL file are as follows: Step 3.1: Create a new workspace using Compaq Visual Fortran (VF) software. Step 3.2: Create a Dynamic Link Library (DL) project within the workspace. Step 3.3: Create a new algorithm file (in .for format) within the project. Step 3.4: After the single .for file is compiled correctly, compile all the files in the entire project into a single .dll file.

[0072] In step 4 of this embodiment, the EMF format file, the TAB format file and the DLL dynamic library file are combined and configured to complete the construction of the simulation system, which is specifically as follows:

[0073] Build the project based on thermal power simulation platform;

[0074] Type the EMF format file into the Icon folder of the project directory, and type the TAB format file and DLL dynamic library file into the ALG folder of the project directory;

[0075] Configure the Giss.ini file in the project directory, and add the paths of EMF format files, TAB format files, and DLL dynamic library files to complete the construction of the simulation system.

[0076] During implementation, the simulation system was built as follows: Step 4.1: Create a new project using the CSSP-2000 thermal power simulation platform software. Step 4.2: Copy the emf file from Step 1 to the Icon folder in the project directory. Step 4.3: Copy the tab file from Step 2 and the dll file from Step 3 to the ALG folder in the project directory. Step 4.4: Configure the Giss.ini file in the project directory to externalize the control system algorithm into the simulation platform.

[0077] In a further implementation of this embodiment, the construction process of the hydropower station VR scene is as follows:

[0078] Create a virtual scene of a hydropower station using the Blender 3D modeling tool;

[0079] Import the virtual scene model of the hydropower station into the VR development platform, adjust the project parameters, and complete the construction of the hydropower station VR scene.

[0080] The VR development platform is provided with a corresponding calling script according to the simulation system, so as to run the corresponding simulation system algorithm by calling the script according to the operation instructions input by the user in the VR device.

[0081] The VR development platform is equipped with multiple perspective modes, including first-person, third-person, and bird's-eye views. Corresponding camera settings are created for each perspective mode, and perspective conversion logic is established. In the visual user interface, the perspective conversion function is bound to the left-hand handle disc button. Users can trigger the perspective mode switch by long-pressing the button (for example, 0.5 seconds), and the switch is smoothed with a short, gradual transition, thereby reducing dizziness and the risk of spatial dislocation. The call script is integrated with the perspective conversion button to ensure seamless collaboration with other function scripts after switching perspectives.

[0082] After entering the VR scene, you can see the three-dimensional scene through the VR helmet, and see the left and right hand images virtualized by the handles in front of your field of view. The user can walk freely and rotate the view within the locator range. When the positioning range is limited and the vertical view needs to be adjusted, you can touch the upper or lower part of the left handle to move up or down; if you need to switch between the first-person and third-person (or bird's-eye) perspectives, you can long press the left handle disc button to complete the conversion. By clicking the disc button on the right handle, the right-hand laser beam is activated (SphereCast can be used to improve accuracy); after the beam intersects with the ground, short press the trigger button to achieve teleportation-style rapid movement, and add an auxiliary aperture indicator at the landing point to improve movement accuracy. When the laser beam falls on an operable device, the beam color changes from green to yellow. At this time, clicking the trigger button again can perform operations on the device and send corresponding instructions to the simulation model. To improve operational feedback and safety, it is recommended to use sound effects or controller vibration prompts when switching perspectives, moving, or operating the device, and set prompt information for communication anomalies to ensure stable data interaction between the VR scene and the simulation system.

[0084] memory for storing computer programs;

[0085] The processor is used to implement the steps of the method for constructing and integrating a virtual simulation system of a hydropower station when executing the computer program.
