[0075] In view of the fact that the existing verification methods for semi-physical prototype systems of aviation platforms are difficult to carry out functional performance tests quickly, the present invention proposes a distributed simulation verification scheme, which adopts a combination of virtual and real methods and is driven by scenario deduction to carry out functional performance verification of semi-physical prototype systems of aviation platforms.

[0076] The distributed simulation verification environment consists of an aviation platform semi-physical prototype system, a digital simulation environment, and a command and control system. Each platform and software is connected through a DDS data bus. The aviation platform semi-physical prototype system is the object to be tested. It can be used to test the functions and performance of each subsystem of the aviation platform. The aviation platform can also be used as a carrier to test its collaborative formation capabilities with the ground platform. The digital simulation environment is used to build a virtual platform model and a simulation deduction plot. The command and control system is used to control the simulation process and record simulation data for analysis and evaluation of the simulation effect.

[0077] Through the above technical scheme, the present invention can test the functional performance of different aspects of the semi-physical prototype system of the aviation platform by setting different storyline deduction scenarios, so as to achieve the purpose of testing different avionics systems after only minor modifications to the test verification environment, thereby improving the efficiency of test verification and accelerating the development of equipment.

[0078] For example, in order to test the aviation platform's capabilities of heterogeneous multi-aircraft formation flying, formation change, path planning, and collaborative search, a complex terrain environment is used as the test environment, and the mission process is designed. According to the evolution of the aviation platform's process in completing the mission, the above-mentioned capabilities and other indicators are tested and verified.

[0079] A typical mission scenario is based on the collaborative search and rescue of a heterogeneous multi-aircraft formation in an uncertain environment. For several rescue targets in an unknown area, a flight formation composed of heterogeneous multi-aircraft will head to the target area and make plans based on information such as the area, shape, and capabilities of our aviation platforms. After receiving the mission, each aviation platform will fly along the designated route and search for the target using airborne radar, optoelectronic and other sensors in order to find the rescue target as early as possible.

[0080] Due to weather factors, several fishing boats were lost in a certain sea area. In order to find the missing boats as soon as possible and rescue the trapped people, it is planned that a flight formation composed of multiple drones will go to the target sea area for search and rescue. After receiving the danger report, the ground terminal commander arranges the aviation platforms to take off in sequence, and after the assembly is completed in the assembly area, the formation flies to the target sea area. On the way, according to the area, shape and capabilities of the aviation platforms in the formation, the lead aircraft will plan the path, divide the search range of each aviation platform and the corresponding flight route, and distribute the results to each platform. After receiving the command, each platform will leave the flight formation when approaching the target area and fly according to the command. During the flight, the aviation platform turns on the airborne radar, optoelectronics and other sensors for detection, and the radar processing subsystem and optoelectronic processing subsystem process the acquired data and transmit the processed information to the task processing software for analysis and identification, determine the location of the target to be rescued, and transmit the data back to the ground command center, which will carry out subsequent rescue activities.

[0081] In this scenario, the object under test 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 collaborative search algorithm. At the same time, the data processing function and navigation function of the radar processing subsystem and optoelectronic processing subsystem are also verified.

[0082] In this scenario, there are three sets of semi-physical prototype systems for aviation platforms, including two types of manned platforms and one type of unmanned aerial vehicle platform. The accompanying test platforms are digital simulation models corresponding to the two types of manned platforms, several offshore rescue targets and a ground command center.

[0083] To realize this preset scenario, each platform needs to be configured. Construct three types of semi-physical prototype systems for aviation platforms, including two different types of manned aircraft and one type of unmanned aircraft. Configure the parameters of the flight simulation subsystem according to the differences in aircraft models to meet the flight characteristics of different aviation platforms; embed the new collaborative search algorithm into the task processing software of each platform, and configure other recording software and sensors, external load simulation subsystems, etc. 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 specified subsystem.

[0084] In the digital simulation environment, it is necessary to build digital simulation models of two types of manned aircraft platforms, ground command centers and several rescue targets. For manned aircraft platforms, it is necessary to configure the kinematic model of the platform, whose flight characteristics are close to the flight simulation subsystem in the semi-physical prototype system; establish a fuel consumption model to simulate the fuel consumption process of the aircraft and limit the aircraft's range; at the same time, establish a communication model to meet the needs of communication with other aircraft in the formation, including communication equipment model, communication transmission channel model, communication quality model and communication network model; establish radar sensor and photoelectric sensor models, radar sensors include transmitters, receivers, antennas, signal processing, resource scheduling, tracking management and other components. For the ground command center model, it is necessary to establish its task processing model and communication model. For the rescue target, set its kinematic model to simulate the irregular movement under the action of sea currents; set its optical characteristics, acoustic characteristics, infrared characteristics and radar characteristics to meet the needs of sensor detection; establish the appearance model of the target to meet the needs of visual display and photoelectric sensor detection of the semi-physical prototype system. After completing the platform model construction, in the digital simulation environment, a behavior processor is built for each digital model, including control transfer, status information reporting, etc., so that each platform can perform deductions according to the preset behavior.

[0085] After completing the above preparations, the command and control system controls the scenario simulation process and records the status information, motion information, communication information, etc. of each platform during the simulation process to facilitate subsequent analysis and evaluation work.

[0086] Therefore, through the constructed distributed simulation verification environment, the functional performance verification of the semi-physical prototype system of the aviation platform can be carried out more quickly, which can speed up the development of equipment. When it is necessary to modify and upgrade a certain airborne hardware and software, it is only necessary to upgrade and replace the corresponding modules in the semi-physical prototype system, and the original scene can be used for verification. At the same time, modifications can be made to combat scenario cases to verify the robustness of the semi-physical prototype system of the aviation platform, and this can be done only by modifying and adjusting the digital simulation environment. Similarly, based on the guidance and control system, the test personnel can intuitively observe the entire simulation process, which is convenient for improving the experimental process, and can also intuitively verify the functionality of the semi-physical prototype system of the aviation platform.

[0087] So far, the purpose of the present invention has been achieved.

[0088] The above are only 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 in the protection scope of the present invention.
