Description

Technical Field

[0001] The present invention relates to the technical field of simulation training, and particularly relates to a communication simulation training method and system based on digital twin. Background Art

[0002] A communication simulation training system is a technical means that provides practical training for operators by simulating real communication devices, network environments, and operation processes. Its purpose is to enable operators to be familiar with the operation of communication devices, the process of network networking, and the ability to handle various communication scenarios (such as interference, faults, etc.) in a virtual or semi-physical environment, thereby improving the efficiency and accuracy in actual operations.

[0003] Currently, communication simulation training systems generally exist in two forms: full-physical simulation and full-virtual simulation. Full-physical simulation is based on all physical communication devices and interference machine devices, etc., to cooperate in communication simulation. The authenticity of the results obtained under a real communication environment is the strongest. However, the construction cost of the scenario is high, the controllability is poor, the flexibility in scenario setting and parameter adjustment is low, and it is difficult to collect data and reproduce faults. Once a fault occurs, it is very likely to damage external devices or even the entire physical environment, resulting in cost losses. Due to being limited by specific conditions, it also limits the scale and flexibility of training.

[0004] Although full-virtual simulation can reduce costs by simulating real communication environment scenarios through software, and the operation is more flexible with strong scalability, the operation of virtual device software lacks realism, is not as intuitive and has a high experience as operating actual equipment, which is likely to affect the enthusiasm of operators. At the same time, full-virtual simulation is limited by the accuracy of the model, and the simulation results are not as accurate as the actual situation. Summary of the Invention

Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the specification of this invention are only for the purpose of describing specific embodiments and are not intended to limit the invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0042] Embodiment 1

[0043] Please refer to Figure 1 , which shows the communication simulation training method based on digital twin in the first embodiment of the present invention, including steps S10 - S14.

[0044] Step S10, register a data display update message callback event through the three - dimensional situation display module and send it to the communication control module. The communication control module loads the formation file and notifies the trigger to call back to the three - dimensional situation display module;

[0045] Specifically, register a data display update message callback event through the three - dimensional situation display module and send it to the communication control module. The communication control module loads the formation file and displays the vehicle and equipment list information under the formation;

[0046] Notify the trigger to call back to the three - dimensional situation display module, and synchronously update and display the vehicle and equipment list information through the three - dimensional situation display module.

[0047] Among them, the three - dimensional situation display module is used to receive the data of the communication control module in real time through registering callback events for synchronous three - dimensional display, which is more intuitive. At the same time, the three - dimensional situation display module supports access to virtual reality devices to achieve an immersive experience, feel the communication simulation effect, and can maximize the learning and usage enthusiasm of operators.

[0048] It should be noted that registering callback events is a common programming pattern, usually used in asynchronous programming, event - driven programming, or handling operations triggered by certain specific conditions. The core idea of callback events is that when a certain event occurs, a pre - defined function (callback function) is automatically called to handle the event.

[0049] Step S11, operate the semi - physical communication equipment through the semi - physical communication equipment module, set the signal parameters required for communication, and report the signal parameters to the communication control module;

[0050] Among them, the hardware-in-the-loop communication equipment module is a hardware-in-the-loop communication equipment simulator, which is internally equipped with an embedded software system. Through the embedded software system, the menu for operating the hardware-in-the-loop communication equipment simulator is implemented, and the parameter information of the operation menu is reported. That is, the hardware-in-the-loop communication equipment is the hardware-in-the-loop communication equipment simulator, and an embedded software system is deployed internally to support data interaction.

[0051] Specifically, when the operator operates the hardware-in-the-loop communication equipment through the hardware-in-the-loop communication equipment module, sets the signal parameters required for communication, and reports the signal parameters to the communication control module, it is judged whether the reporting is successful;

[0052] If so, proceed to the next step;

[0053] If not, repeat the above steps of operating the hardware-in-the-loop communication equipment through the hardware-in-the-loop communication equipment module until the reporting is successful.

[0054] Among them, the hardware-in-the-loop communication equipment module is used to provide the hardware-in-the-loop communication equipment for specific operations in communication simulation training, allowing the operator to directly operate the corresponding hardware-in-the-loop communication equipment, which can improve the realism of the operation and the experience.

[0055] By way of example and not limitation, for example, a number of virtual vehicle nodes including a general communication vehicle, an intelligence vehicle, an access vehicle, a tracked battalion command vehicle, and a tracked company command vehicle can be constructed, covering a number of hardware-in-the-loop communication equipment including a VHF radio, a shortwave radio, a high-speed data radio, vehicle communication, a multi-functional telephone, area broadband, satellite communication, microwave, scatter, and a communication controller.

[0056] Step S12, the communication control module feeds back the networking status to the hardware-in-the-loop communication equipment module, matches and controls the networking, updates the networking status through the hardware-in-the-loop communication equipment module, and simulates the communication mode;

[0057] Specifically, based on the signal parameters, the communication control module feeds back the networking status to the hardware-in-the-loop communication equipment module, updates the networking status through the hardware-in-the-loop communication equipment module, and simulates the communication mode;

[0058] And notifies the trigger to call back to the 3D situation display module, and synchronously updates and displays the signal parameters through the 3D situation display module;

[0059] Then matches and controls the networking, notifies the trigger to call back to the 3D situation display module, and synchronously updates and displays the networking status through the 3D situation display module.

[0060] Among them, the communication mode includes a voice communication mode and a data communication mode.

[0061] Step S13: Simulate the electromagnetic interference environment through the electromagnetic environment module and feed the interference information back to the communication control module;

[0062] Step S14: The communication control module updates the networking information based on the interference information and feeds back the communication effect to the semi-physical communication equipment module to update the communication effect in the communication mode.

[0063] After the step where the communication control module updates the networking information based on the interference information and feeds back the communication effect to the semi-physical communication equipment module to update the communication effect in the communication mode, the following steps are further included:

[0064] The communication control module notifies the trigger to call back to the three-dimensional situation display module, and the three-dimensional situation display module synchronously updates and displays the networking information in the networking state.

[0065] Among them, the communication control module respectively receives the signal parameters of the semi-physical communication equipment module and the interference information of the electromagnetic environment module, controls the networking state of the communication equipment in the communication simulation training and the networking information in the networking state based on this information, and displays it through the three-dimensional situation display module.

[0066] In addition, operate the semi-physical communication equipment of the physical entity, virtually map the parameter information to the three-dimensional situation module, and realize real-time synchronization of virtual and real data through parameter information acquisition to realize the digital twin technology.

[0067] It should be noted that this method uses a combination of semi-physical communication equipment and virtual simulation. The semi-physical communication equipment is used to improve the operation and use fidelity, and other information such as the electromagnetic interference environment is flexibly configured using the virtual simulation method. At the same time, it combines the three-dimensional presentation method, which is more intuitive. It avoids the problem that the full-physical solution requires all physical objects, and the operation and configuration are not flexible enough; and the full-virtual simulation solution uses all virtual software simulations, and the operation and use are not realistic enough.

[0068] In addition, this method reduces the cost of the full-physical method, enables the operator to feel the fidelity of the operation of the semi-physical communication equipment to a great extent, and can flexibly and conveniently simulate and configure various types of communication scenarios and electromagnetic environment interference conditions, and can present the communication information of the whole system in a three-dimensional way in real-time synchronization, which is more intuitive and easier to improve the enthusiasm of the operator.

[0069] In summary, in the above embodiments of the present invention, the communication simulation training method based on digital twin uses semi-physical communication equipment through the semi-physical communication equipment module to improve the operational realism. The electromagnetic environment module uses virtual simulation to flexibly configure the scenario and electromagnetic interference environment, improving flexibility and accuracy. The communication control module receives the signal parameters of the semi-physical communication equipment module and the interference information of the electromagnetic environment module respectively, controls the networking state of the communication equipment in the communication simulation training and the networking information in the networking state based on this information, and displays it through the three-dimensional situation display module. Combining the three-dimensional presentation method, it is more intuitive, thus solving the technical problems of low flexibility in full-physical simulation and low accuracy in full-virtual simulation.

[0074] The electromagnetic environment module 200 is used to simulate the electromagnetic interference environment and feedback the interference information to the communication control module 300;

[0075] The communication control module 300 is used to receive the signal parameters and the interference information, obtain the networking information in the networking state, and notify and trigger a callback to the three-dimensional situation display module 400 to update the display.

[0076] In summary, in the above embodiments of the present invention, the communication simulation training system based on digital twin uses semi-physical communication equipment through the semi-physical communication equipment module to improve the operational realism.
