[0031] The aircraft communication control device generally sets up a radio station between the aircraft and the ground control center to realize the control of the flight state of the aircraft, and the radio station of the existing aircraft communication control device is difficult to work normally in the case of signal interference, thereby causing certain safety hazards to the flight of the aircraft. To this end, the embodiments of the present application provide a redundant radio station communication control device and a flight system to solve the above problems.

[0032] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. The following examples and features in the examples can be combined with each other without conflict.

[0033] Please refer to Figure 1 , Figure 1 The structure schematic block diagram of the redundant radio station communication control device 100 provided by the embodiments of the present application is shown in the figure, and the redundant radio station communication control device 100 provided by the embodiments of the present application is used to control the flight state of the aircraft, as shown in the figure, the redundant radio station communication control device 100 includes a communication switching board 110, a rocker module 120, a plurality of groups of communication stations 130 and a switch module 140; wherein the communication frequency bands used by each communication station 130 are different from each other, and the rocker module 120, the communication station 130 and the switch module 140 are all in communication connection with the communication switching board 110. Figure 1

[0034] Among them, "redundancy" refers to the fact that a system, component or part of a system can exceed the minimum requirement or additional capacity required by the actual need. In the field of communication, redundancy can be explained as the redundancy of signals, which refers to the additional measures or redundant parts in the system for fault tolerance and stability. When the signal is disturbed or noisy, redundancy can help reduce the failure rate of signal reception, thereby improving the efficiency and reliability of communication.

[0035] The redundant radio station communication control device 100 provided by the embodiments of the present application sets a plurality of communication stations 130 with different communication frequency bands for the redundant radio station communication control device 100, so that when the communication station 130 in the working state is disturbed by the signal, other communication stations 130 can continue to realize the normal communication between the aircraft and the ground, thereby improving the safety of the flight of the aircraft.

[0036] As shown in Figure 2 ​As shown, in some embodiments, the excess degree radio communication control device 100 further comprises a controller 150 with display function, the controller 150 is in communication connection with the communication adapter 110, and the controller 150 is used to display the flight state of the aircraft based on the control parameter information of the joystick module 120.

[0037] The controller 150 can be any one of a notebook computer, a desktop computer, a tablet computer, a mobile phone or a wearable device.

[0038] In this embodiment, by providing the controller 150 for the excess degree radio communication control device 100, the staff or user can know the flight state of the aircraft in real time on the ground through the controller 150, so as to facilitate the staff or user to control the flight state of the aircraft more accurately, thereby improving the safety of the aircraft during flight.

[0039] In some embodiments, the method for displaying the flight state of the aircraft based on the control parameter information of the joystick module 120 by the controller 150 comprises the following steps:

[0040] Obtaining the control parameter information of the joystick module 120, and obtaining the flight state of the aircraft based on a preset flight state prediction model and the control parameter information;

[0041] Displaying the flight state of the aircraft to the user.

[0042] In some embodiments, the training method of the flight state prediction model comprises:

[0043] Obtaining an initial training sample set, the initial training sample set comprising a plurality of mapping relationships, the mapping relationship being a mapping relationship between a real flight state of an aircraft and control parameter information corresponding to the real flight state, the control parameter information comprising a plurality of control parameters;

[0044] Based on the initial training sample set, a discrete distribution graph is constructed between the real flight state and each control parameter;

[0045] Based on all the discrete distribution graphs, the weight corresponding to each control parameter is determined;

[0046] Based on the weight corresponding to each control parameter, the control parameters in the training sample set are labeled to obtain a training sample set;

[0047] Based on the training sample set, a preset initial flight state prediction model is trained to obtain the flight state prediction model.

[0048] For example, the weight corresponding to each control parameter based on all the discrete distribution graphs can be realized in the following way:

[0049] determine a dispersion degree of each of the discrete distribution maps based on a preset image analysis model;

[0050] arrange each of the dispersion degrees from high to low in sequence to obtain a dispersion degree ranking table, and determine a weight corresponding to each of the parameters based on the dispersion degree ranking table.

[0051] Exemplarily, the preset initial flight state prediction model is trained based on the training sample set to obtain the flight state prediction model, which can be realized in the following manner:

[0052] The training sample set is divided into a training set, a test set and a correction set, and the training set includes multiple training samples;

[0053] Each of the initial flight state prediction models is trained based on each of the training sets to obtain multiple first intermediate flight state prediction models;

[0054] Each of the first intermediate flight state prediction models is detected by using the test set to obtain a prediction accuracy of each of the first intermediate flight state prediction models;

[0055] Each of the accuracies is compared with a preset accuracy, and when the accuracy is greater than the preset accuracy, the first intermediate flight state prediction model corresponding to the accuracy is determined as a second intermediate flight state prediction model;

[0056] Model parameters of all the second intermediate flight state prediction models are fused and calculated to obtain fused model parameters, and a third intermediate flight state prediction model is obtained based on the fused model parameters;

[0059] A prediction loss function of the third intermediate flight state prediction model is obtained based on the prediction flight state-real flight state mapping table;

[0060] The third intermediate flight state prediction model is corrected based on the prediction loss function to obtain the flight state prediction model.

[0061] The training method of the flight state prediction model provided in the embodiment can improve the training speed of the flight state prediction model by taking the weight corresponding to each control parameter as a consideration factor in the process of training the flight state prediction model based on the training sample set, and reasonably selecting each control parameter in the training data set.
