[0063] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0064] It should be understood that in the embodiments of the present disclosure, the character " / " generally indicates that the objects associated with each other are in an "or" relationship. The terms "first", "second", etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0065] As the level of aircraft informatization and intelligence becomes higher and higher, the complexity of aircraft increases greatly, and the amount of data from aircraft flight tests increases significantly.

[0066] The current method of processing flight test data is: after the flight, the flight test data recorded by the onboard recorder is unloaded to the data server through professional unloading software, and provided to data processing personnel for data processing.

[0067] However, the current method of processing flight test data is time-consuming and affects the efficiency of flight tests.

[0068] For example, as the level of aircraft informatization and intelligence increases, the complexity of aircraft increases greatly, and the amount of flight test data of aircraft surges. The air-to-ground communication method used in aviation flight tests is: the test flight engineer informs the required flight mission parameters in advance, and the test engineer loads the configuration and extracts the parameters of the onboard equipment through traditional point-to-point telemetry communication. The current available frequency band for telemetry is the S band, and the bandwidth resources of the S band are tight, the transmission rate is limited, and the amount of air-to-ground transmission parameters is limited. When the flight mission parameters need to be added or changed again, it is necessary to repeatedly load the configuration and extract the onboard parameters, resulting in a waste of human resources and complex flight mission links, affecting the efficiency of flight implementation evaluation and the progress of the mission. In addition, the massive original flight mission parameters recorded in the flight mission need to adopt the mode of "manual disk delivery-data unloading-post-processing". There are many data transmission and processing links and a low degree of automation, resulting in large resource requirements and long data processing time, which has become a bottleneck restricting the improvement of the timeliness of flight data acquisition.

[0069] Under this background technology, the present disclosure provides a 5G air-to-ground network communication system based on flight tests, which can improve the degree of automation in obtaining flight mission parameters and improve the timeliness of obtaining flight mission parameters.

[0070] Figure 1 The schematic diagram of the principle of the 5G air-to-ground network communication system based on the flight test provided by the embodiment of the present disclosure. Figure 1 As shown, the above-mentioned 5G air-ground network communication system based on flight test may include an airborne terminal system and a ground terminal system, wherein the airborne terminal system includes an airborne data processing unit, a 5G terminal for aviation flight test, and an airborne 5G antenna, and the ground terminal system includes a flight test dedicated network, an air-ground network control platform, and a flight test data management platform.

[0071] The airborne data processing unit is connected to the 5G terminal for aviation flight test, the 5G terminal for aviation flight test is connected to the airborne 5G antenna, the test flight dedicated network is connected to the air-ground network control platform, and the air-ground network control platform is connected to the test flight data management platform. The 5G terminal for aviation flight test is used to send access requests to the test flight dedicated network. The test flight dedicated network is used to receive access requests sent by the 5G terminal for aviation flight test and establish an air-ground network communication link. The air-ground network control platform is used to send instruction information to the test flight data management platform, and the instruction information is used to instruct the test flight data management platform to send flight mission reservation information to the airborne data processing unit. The test flight data management platform is used to receive the instruction information sent by the air-ground network control platform, and send flight mission reservation information to the airborne data processing unit according to the instruction information. The flight mission reservation information includes basic aircraft information and pre-processing task information. The onboard data processing unit is used to receive the flight mission reservation information sent by the flight test data management platform, establish a flight-related subject parameter file based on the flight mission reservation information, obtain the flight mission parameters based on the flight-related subject parameter file, and send the flight mission parameters to the flight test data management platform through the 5G terminal for aviation flight test and the onboard 5G antenna. The flight test data management platform is used to receive the flight mission parameters sent by the onboard data processing unit.

[0072] Exemplarily, the above-mentioned 5G air-ground network communication system based on flight test can be an air-ground 5G network communication system for aviation flight test, the 5G terminal for aviation flight test can be an aviation flight test 5G terminal, the air-ground network control platform can be an air-ground 5G network control platform, and the air-ground network communication link can be an air-ground 5G network communication link. The 5G air-ground network communication system based on flight test may include an airborne terminal system and a ground terminal system, and the airborne terminal system and the ground terminal system can be connected through a 5G wireless network. Among them, the airborne terminal system includes an airborne data processing unit, a 5G terminal for aviation flight test, and an airborne 5G antenna, and the ground terminal system includes a test flight network, an air-ground network control platform, and a test flight data management platform. The airborne data processing unit, the 5G terminal for aviation flight test, and the airborne 5G antenna are connected in sequence, and the test flight network, the air-ground network control platform, and the test flight data management platform are connected in sequence. During the flight, the aircraft can use the 5G terminal for aviation flight test to send an access request to the flight test private network. After receiving the access request sent by the 5G terminal for aviation flight test, the flight test private network connects to the aircraft through the 5G wireless network, thereby establishing an air-to-ground 5G network communication link. At this time, the air-to-ground network control platform can inform the flight test data management platform that the 5G terminal for aviation flight test has been connected to the flight test private network through the control standard communication protocol, and can send flight mission reservation information to the airborne data processing unit. Among them, the control standard communication protocol of the air-to-ground 5G network control platform may include: header identifier, data header, data body, and tail identifier, defining the flight test 5G private network protocol header: 0x0001~0x0099, airborne processing and dump unit protocol header: 0x0101~0x0199, aviation flight test 5G terminal protocol header: 0x0201~0x0299, and flight test data reservation push platform protocol header: 0x0301~0x0399. After receiving the instruction information sent by the air-ground network control platform, the flight test data management platform can send the flight mission reservation information to the airborne data processing unit according to the instruction information, wherein the flight mission reservation information may include basic aircraft information and pre-processing task information. The basic aircraft information may include aircraft model information, aircraft test flight subject information, aircraft test system maintenance information, flight data attribute maintenance information, etc., wherein the flight data attribute maintenance information may include the attribution maintenance of information such as the aircraft model, subject supervisor, subject name, subject code, creation time, creator, and responsible unit. The pre-processing task information may include aircraft header file information, aircraft processing library information, aircraft processing subject information, pre-processing task initiation information, etc.After the onboard data processing unit receives the flight mission reservation information sent by the test flight data management platform, it can establish a flight-related subject parameter file based on the flight mission reservation information, and obtain the flight mission parameters of the aircraft based on the flight-related subject parameter file, and then transmit the flight mission parameters to the 5G terminal for aviation flight test. After the 5G terminal for aviation flight test receives the flight mission parameters, it sends the flight mission parameters to the test flight data management platform through the onboard 5G antenna connected to the 5G terminal for aviation flight test. The test flight data management platform can receive the flight mission parameters sent by the onboard data processing unit. After the flight mission parameters are transmitted, the onboard data processing unit can send a signal to the air-ground network control platform to inform the air-ground network control platform that the flight mission process has ended.

[0073] The disclosed embodiment proposes a 5G air-ground network communication system based on flight test, which may include an airborne terminal system and a ground terminal system, wherein the airborne terminal system includes an airborne data processing unit, a 5G terminal for aviation flight test, and an airborne 5G antenna, and the ground terminal system includes a dedicated flight test network, an air-ground network control platform, and a flight test data management platform. The airborne data processing unit is connected to the 5G terminal for aviation flight test, the 5G terminal for aviation flight test is connected to the airborne 5G antenna, the dedicated flight test network is connected to the air-ground network control platform, and the air-ground network control platform is connected to the flight test data management platform. Through the 5G air-ground network communication system based on flight test, it is possible to realize pre-flight mission parameter reservation, in-flight mission parameter extraction and solution and real-time communication, and high-speed wireless unloading of massive original parameters after flight, which can improve the degree of automation of obtaining flight mission parameters and improve the timeliness of obtaining flight mission parameters.

[0074] In some embodiments, the flight test dedicated network includes at least two ground base stations and an air-ground network management and control platform, which is also used to control the switching access between the 5G terminal used for aviation flight tests and the ground base station in the flight test dedicated network according to the received signal power and signal-to-noise ratio of the ground base station.

[0075] Exemplarily, the flight test dedicated network may include at least two ground base stations. The air-ground network control platform can control the 5G terminals used for aviation flight tests to switch after connecting to the ground base stations in the flight test dedicated network based on indicators such as the received signal power and signal-to-noise ratio of the ground base stations.

[0076] For example, taking the test flight dedicated network including base station 1, base station 2, base station 3, base station 4, base station 5, and base station 6 as an example, after the 5G terminal for aviation flight test of aircraft A sends an access request to the test flight dedicated network, base station 1 in the test flight dedicated network is wirelessly connected to aircraft A. During the continuous flight of aircraft A, the air-ground network control and management platform detects that the connection signal between base station 1 and aircraft A is weak, and the connection signal between base station 3 and aircraft A is the strongest based on the received signal power and signal-to-noise ratio of all base stations in the test flight dedicated network. At this time, the air-ground network control and management platform can send a signal to the 5G terminal for aviation flight test of aircraft A, informing the 5G terminal for aviation flight test of aircraft A to disconnect from base station 1 and establish a wireless connection with base station 3, thereby completing the switching access of the 5G terminal for aviation flight test from base station 1 to base station 3.

[0077] In this embodiment, the flight test network is limited to include at least two ground base stations, and the air-ground network control platform is also used to control the switching access between the 5G terminal for aviation flight test and the ground base station in the flight test network according to the received signal power and signal-to-noise ratio of the ground base station. The continuity and stability of the aircraft signal can be maintained, further ensuring the stability of data transmission.

[0078] In some embodiments, the air-ground network control platform is also used to monitor the working status of airborne data processing units, 5G terminals for aviation flight tests, and ground base stations in the flight test private network.

[0079] Illustratively, the air-ground network control and management platform can monitor the working status and fault display of airborne data processing units, 5G terminals for aviation flight tests, and ground base stations in the flight test dedicated network. It can also monitor and display aircraft information, flight-related subject parameters, transmission rates of air-ground network communication links and other information in real time. It can also control the restart, startup, shutdown and program upgrade of airborne data processing units, 5G terminals for aviation flight tests and other equipment.

[0080] This embodiment limits the air-ground network control platform to also monitor the working status of airborne data processing units, 5G terminals for aviation flight tests, and ground base stations in the flight test private network. It can monitor the working status of each device in real time, handle failures in a timely manner, and ensure the normal operation of the above-mentioned 5G air-ground network communication system based on flight tests.

[0081] In some embodiments, the air-ground network control platform is also used to determine the flight state of the aircraft based on the aircraft state parameters, and determine the working frequency band of the air-ground network communication link based on the flight state of the aircraft.

[0082] Exemplarily, the aircraft status parameters may include the aircraft landing gear status and the engine reverse thrust parameters. The air-ground network control platform may jointly determine the flight status of the aircraft based on the aircraft landing gear status and the engine reverse thrust parameters, and then determine the operating frequency band of the air-ground network communication link based on the determined flight status of the aircraft. The flight status of the aircraft may include flying and landing.

[0083] For example, the air-ground network control and management platform can extract the aircraft landing gear status and engine reverse thrust parameters to jointly determine the flight status of the aircraft. When it is determined that the flight status of the aircraft is in flight, the air-ground 5G network control and management platform can send a signal to inform the air-ground 5G network communication link to work in the 5G C band. At this time, the airborne data processing unit can transmit the parameters that can evaluate the flight performance of the aircraft in real time to the test flight data management platform through the air-ground 5G network communication link. When it is determined that the flight status of the aircraft has landed, the air-ground 5G network control and management platform can send a signal to inform the air-ground 5G network communication link to work in the 5G S+C band. At this time, the airborne data processing unit can transmit a large number of original flight mission parameters to the test flight data management platform through the air-ground 5G network communication link.

[0084] This embodiment defines that the air-ground network control platform is also used to determine the flight state of the aircraft according to the aircraft state parameters, and determines the working frequency band of the air-ground network communication link according to the flight state of the aircraft. The working frequency band of the network communication link can be switched according to the flight state of the aircraft, which alleviates the problems of tight frequency band resources and limited transmission rate, replaces the traditional telemetry communication mode, and reduces the difficulty of unloading the original parameters of massive flight missions.

[0085] In some embodiments, the flight mission parameters include a first parameter and a second parameter, the second parameter is an original parameter of the aircraft, and the onboard data processing unit is further used to convert the first parameter through a conversion algorithm to obtain a real-time evaluation parameter.

[0086] Exemplarily, the above conversion algorithm includes at least one of the following: linear, polynomial, hyperbola, parabola, point-to-segment conversion. The flight mission parameter may include a first parameter and a second parameter, wherein the first parameter is a parameter capable of evaluating the flight performance of the aircraft in real time, and the second parameter is an original parameter of the aircraft. During the flight of the aircraft, the onboard data processing unit converts the first parameter, i.e., the parameter capable of evaluating the flight performance of the aircraft in real time, to obtain a real-time evaluation parameter.

[0087] In this embodiment, the flight mission parameters are defined to include a first parameter and a second parameter, the second parameter being the original parameter of the aircraft, and the onboard data processing unit is further used to convert the first parameter through a conversion algorithm to obtain a real-time evaluation parameter. The real-time evaluation parameter can be obtained during the flight and transmitted to the flight test data management platform, thereby improving the automation level of obtaining the flight mission parameters and improving the timeliness of obtaining the flight mission parameters.
