[0019] Figure 5 A schematic diagram illustrating data interaction between this invention and other systems in the program trainer; Detailed Implementation

[0020] like Figure 1 As shown, the present invention comprises ten modules: a high-precision timer, a UDP communication module, a command and control module, a simulation scheduling module, a flight simulation initialization and trim module, a flight simulation PFD display module, a flight simulation data display module, a control data acquisition module, an aircraft performance simulation model, and an aircraft electromechanical system simulation model.

[0021] Each module (excluding the aircraft performance simulation model and the aircraft electromechanical system simulation model) is encapsulated into a single software program, implemented using C++ and QT. Communication between modules is achieved through memory read / write or signal and slot functions, offering superior stability and operability compared to traditional UDP or TCP methods.

[0022] The guide control module is a simple UI human-computer interaction module, which completes initialization setting of the flight simulation platform when the instructor station system participates in debugging, simulation initialization, start, pause, and end setting. A UI interface diagram of the module is shown in Figure 2 ;

[0023] The guide control module sends initialization information to the simulation scheduling module and sends start, pause, and other signals to the high-precision timer module;

[0024] The high-precision timer module uses boost::chrono in the Boost library to implement a high-precision timer. After receiving the start signal sent by the guide control module, the high-precision timer module starts the technology and sends a signal to the simulation scheduling module every interval step time;

[0025] The high-precision timer module can realize the speed simulation of the simulator by setting the step length of the time signal sending;

[0026] The UDP communication module uses traditional UDP communication technology to receive signals from external systems such as the instructor station and the visual system, unpacks and writes into the simulation scheduling module, and further writes into the simulation model. At the same time, the simulation model signals are packaged and sent to external systems such as the visual system and the display system;

[0027] The control data acquisition module is divided into two sub-modules, namely the peripheral acquisition sub-module and the virtual input sub-module. The peripheral acquisition sub-module acquires the control signals of the joystick and the throttle station, and realizes the signal acquisition through the WinUSB USB acquisition library. The virtual input sub-module, as shown in Figure 3 , enters the input interface required by the flight simulation model through the UI interface. In addition, the input amount of the joystick and the throttle lever is displayed in the form of a progress bar, and the progress bar can also be directly dragged for control when there is no physical joystick and throttle;

[0028] The simulation scheduling module controls the simulation model by writing simulation initialization function sim_intial(), simulation start function sim_start(), simulation stop function sim_stop(), and simulation reset function sim_reset() functions;

[0029] The simulation scheduling module can schedule simulation models in the form of source code, dll, or FMU. The tool guide control module or the instructor station system inputs the model setting of the aircraft type to select the simulation model, and realizes the writing of the initialization data and input data of the simulation model and the reading of the output data of the simulation model;

[0030] The simulation scheduling module obtains the data of the simulation model and sends it to other modules and external systems as corresponding data excitation to realize the flight simulation function;

[0031] The flight simulation initialization trim module realizes the initialization trim of the airplane simulation model by writing a trim() function in C++, so that the airplane can fly steadily in the state specified by the instructor station.

[0032] The flight simulation PFD display module receives the airplane PFD information output by the simulation scheduling module, and displays the information in the form of a data list, as shown in Figure 4

[0033] The flight simulation data display module receives the airplane simulation data output by the simulation scheduling module, and displays the data in the form of a data list, as shown in Figure 4

[0034] The airplane performance simulation model realizes the flight dynamics simulation of the airplane, and is modeled by using C / C++ or other modeling tools, and is provided in the form of source code, dll or FMU for scheduling by the simulation scheduling module.

[0035] The integrated flight simulation platform stores flight performance simulation models of different types of airplanes, including civil aviation passenger airplanes, fighter jets, transport airplanes, helicopters, fixed-wing unmanned aerial vehicles and multi-rotor unmanned aerial vehicles, which are used as data excitation for different program training simulators.

[0036] The airplane electromechanical system simulation model is modeled according to the model characteristics of different program training simulators by using C / C++ or other modeling tools, and is provided in the form of source code, dll or FMU for scheduling by the simulation scheduling module.

[0037] The integrated flight simulation platform of the application interacts with the program training external system information, as shown in Figure 5 The dashed line in the figure indicates that the corresponding system connected by the dashed line can not participate in the joint simulation or debugging when the application is in use, and the platform can be independently run or jointly simulated with other one or more systems.

[0038] For airplane program training simulators and other simulators that do not require high flight performance data, the platform can provide data excitation to realize flight simulation.

[0039] The application can realize simulation data input and display through a UI interface, and solve the problem of lack of basic data input and data monitoring function in the debugging of a traditional flight simulation system.

[0040] When some subsystems of the airplane program training simulator do not have a debugging state, the application can provide data excitation and data response test for the subsystems required for debugging.​​
