[0001] This invention relates to, but is not limited to, the field of distributed simulation verification technology, and specifically to a distributed simulation verification method and system for a semi-physical prototype system of an aviation platform. Background Technology

[0002] Distributed simulation is a computer network-based simulation technology with wide applications in fields such as transportation, chemical engineering, military, biology, and communications. However, current distributed simulation systems struggle to meet the functional performance testing requirements of hardware-in-the-loop (HIL) prototype systems for aerospace platforms. Furthermore, the accompanying digital simulation environments suffer from low data accuracy, making it difficult to construct high-precision red-blue team (RBF) adversarial environments for verifying HIL prototype systems.

[0003] This invention addresses the testing and verification of semi-physical prototype systems for aviation platforms by proposing a distributed simulation verification method. Based on a digital simulation environment and a guidance and control system, a distributed simulation verification environment is constructed, providing a foundation for the testing and verification of semi-physical prototype systems for aviation platforms. Summary of the Invention

[0004] The purpose of this invention is to address the functional performance testing problem of semi-physical prototype systems for aviation platforms. Based on these systems, a distributed simulation test verification method is proposed, enabling the functional performance of semi-physical prototype systems to be verified in a virtual-physical combined manner, thus providing support for the software and hardware development and upgrade of such systems.

[0006] A distributed simulation verification method for a semi-physical prototype system of an aerospace platform includes the following steps:

[0007] The semi-physical prototype system of the aviation platform to be verified, the guidance and control system, and the digital simulation environment are respectively connected to the distributed simulation environment;

[0008] The guidance and control system issues a self-test command to check whether the physical prototype system and digital simulation environment are properly connected to the distributed simulation environment.

[0009] When the semi-physical prototype system and digital simulation environment receive the self-test command, they send their own status information to the command and control system.

[0075] Given that existing verification methods for semi-physical prototype systems of aviation platforms are difficult to conduct functional performance testing quickly, this invention proposes a distributed simulation verification scheme that uses a combination of virtual and physical methods and is driven by scenario deduction to conduct functional performance verification of semi-physical prototype systems of aviation platforms.

[0076] The distributed simulation verification environment comprises a semi-physical prototype system of an airborne platform, a digital simulation environment, and a command and control system. The platforms and software are connected via a DDS data bus. The semi-physical prototype system serves as the object under test, used to test the functionality and performance of each subsystem of the airborne platform. It can also be used as a platform to test its collaborative formation capabilities with ground platforms. The digital simulation environment is used to construct virtual platform models and build simulation scenarios. The command and control system controls the simulation process and records simulation data for analysis and evaluation of the simulation's effectiveness.

[0077] Through the above technical solution, the present invention can test different aspects of the functional performance of the semi-physical prototype system of the aviation platform by setting different scenario scenarios, thereby achieving the goal of testing different avionics systems with only minor modifications to the test and verification environment, improving the efficiency of test and verification, and accelerating the development speed of equipment.

[0078] For example, to test the capabilities of an aviation platform in heterogeneous multi-aircraft formation flight, formation changes, path planning, and collaborative search, a complex terrain environment is used as the test environment. The mission process is designed, and the above-mentioned capabilities and other indicators are tested and verified based on the evolution of the aviation platform in completing the mission.

[0079] A typical mission scenario is a collaborative search and rescue operation by a heterogeneous multi-aircraft formation in an uncertain environment. Several targets to be rescued exist in an unknown area. A flight formation composed of heterogeneous multi-aircraft will head to the target area. The flight plan is based on information such as the area and shape of the target area and the capabilities of our aviation platforms. After receiving the mission, each aviation platform will fly along the designated route and use airborne radar, photoelectric and other sensors to search for the target in order to find the target to be rescued as soon as possible.

[0080] Due to weather conditions, several fishing boats went missing in a certain sea area. To locate the missing vessels and rescue the stranded personnel as soon as possible, a search and rescue operation was planned, consisting of multiple drones forming a flight formation to the target area. Upon receiving the distress report, ground control personnel arranged for the drone platforms to take off sequentially and assemble at the designated assembly area before flying in formation to the target area. En route, based on the area's size, shape, and the capabilities of the drone platforms in the formation, the lead aircraft planned the route, defining the search area and corresponding flight path for each platform and distributing the results to each platform. Upon receiving instructions, each platform broke away from the flight formation as it approached the target area and flew according to the instructions. During flight, the drone platforms activated their onboard radar and electro-optical sensors for detection. The radar and electro-optical processing subsystems processed the acquired data and transmitted the processed information to the mission processing software for analysis and identification, determining the location of the target to be rescued and transmitting the data back to the ground command center for subsequent rescue operations.

[0081] In this scenario, the tested object is the task processing software in the semi-physical prototype system of the aviation platform. The focus is on testing the search process, task allocation results, and robustness of the corresponding cooperative search algorithm. At the same time, the data processing function and navigation function of the radar processing subsystem and the optoelectronic processing subsystem are also verified.

[0082] In this scenario, there are three semi-physical prototype systems for the aviation platform: two types of manned aircraft platforms and one type of unmanned aircraft platform. The test platforms consist of digital simulation models of the two types of manned aircraft platforms, several maritime targets awaiting rescue, and a ground command center.

[0083] To achieve this preset scenario, each platform needs to be configured. Three semi-physical prototype systems for aviation platforms are constructed: two different manned aircraft and one unmanned aircraft. The parameters of the flight simulation subsystem are configured according to the differences in aircraft models to meet the flight characteristics of different aviation platforms. A new cooperative search algorithm is embedded into the task processing software of each platform, and other recording software, sensor, and external attachment simulation subsystems are configured according to the requirements of each platform. The flight simulation subsystem receives data from the digital simulation environment and other semi-physical prototype systems, and receives instructions from its own semi-physical prototype system, generates simulation stimuli in a specified format, and sends the generated stimuli to the designated subsystems.

[0084] In the digital simulation environment, digital simulation models of two types of manned aircraft platforms, a ground command center, and several targets awaiting rescue need to be constructed. For the manned aircraft platforms, a kinematic model needs to be configured, with flight characteristics closely resembling the flight simulation subsystem in the hardware-in-the-loop system; a fuel consumption model needs to be established to simulate the aircraft's fuel consumption process and limit its range; simultaneously, a communication model needs to be established to meet the communication needs with other aircraft in the formation, including communication equipment models, communication transmission channel models, communication quality models, and communication network models; radar sensor and optoelectronic sensor models need to be established, with radar sensors including transmitters, receivers, antennas, signal processing, resource scheduling, and tracking management components. For the ground command center model, its task processing model and communication model need to be established. For the targets awaiting rescue, a kinematic model needs to be set to simulate the irregular movement under the influence of ocean currents; its optical, acoustic, infrared, and radar characteristics need to be set to meet the sensor detection requirements; and an appearance model needs to be established to meet the visual display and optoelectronic sensor detection requirements of the hardware-in-the-loop system. After the platform model is built, behavior processors are constructed for each digital model in the digital simulation environment, including control handover and status information reporting, so that each platform can perform simulations according to preset behaviors.

[0085] After completing the above preparations, the scenario simulation process is controlled by the guidance and control system, and the status information, motion information, and communication information of each platform during the simulation are recorded to facilitate subsequent analysis and evaluation.

[0086] Therefore, the constructed distributed simulation verification environment enables rapid functional performance verification of the hardware-in-the-loop platform prototype system, accelerating equipment development. When upgrading airborne hardware or software, only the corresponding modules in the hardware-in-the-loop prototype system need to be upgraded or replaced, allowing verification using the original scenario. Simultaneously, modifications can be made to combat scenario examples to verify the robustness of the hardware-in-the-loop platform prototype system, which can be accomplished simply by modifying and adjusting the digital simulation environment. Similarly, based on the command and control system, test personnel can intuitively observe the entire simulation process, facilitating improvements to the experimental procedures and providing direct verification of the functionality of the hardware-in-the-loop platform prototype system.

[0087] Thus, the objective of this invention has been achieved.

[0088] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
