[0038] The following description of exemplary embodiments of the present disclosure is provided in conjunction with the accompanying drawings, which include various details of the embodiments of the present disclosure to facilitate understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize 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.

[0039] It should be understood that in the various embodiments of the present disclosure, the character " / " generally indicates an "or" relationship between the preceding and following related objects. The terms "first," "second," etc. are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features.

[0040] As the level of aircraft informationization and intelligence becomes higher and higher, the complexity of aircraft increases greatly, and the amount of data from aircraft flight tests increases substantially.

[0041] The current method of processing flight test data is to provide the equipment storing flight test data on the test aircraft to data processing personnel for data transmission and processing.

[0042] However, the current method of processing flight test data is time-consuming and affects the efficiency of flight tests.

[0043] For example, as aircraft become increasingly information-based and intelligent, their complexity has dramatically increased, leading to a surge in the volume of flight test data. For example, during the C919 large passenger aircraft test flight, over tens of thousands of parameters are collected, resulting in hundreds of gigabytes (GB) of test data recorded per flight. The current approach to processing flight test data is a "manual upload-data offload-post-processing" model. This involves offloading flight test data from onboard recorders to a data server after the flight, using specialized offload software for bitstream analysis as needed. The data is then provided to data processors for pre-processing and secondary processing. However, this current approach to processing flight test data results in lengthy data offload processing times, hindering the timeliness of data acquisition for research projects and impacting flight test efficiency.

[0044] Against this background technology, the present disclosure provides a 5G terminal for aviation flight tests, which can reduce the time for processing flight test data, increase the transmission rate of flight test data, and thus improve the efficiency of flight tests.

[0045] In an exemplary embodiment, the 5G terminal for aviation flight testing provided by the present disclosure can be used to transmit flight test data of an aircraft.

[0046] Figure 1This is a schematic diagram of the principle of a 5G terminal for aviation flight testing provided in an embodiment of the present disclosure. Figure 1 As shown, the 5G terminal for aviation flight testing may include: a power management unit, an airborne flight data processing unit, a first 5G frequency band communication unit, and a second 5G frequency band communication unit.

[0047] The power management unit is connected to the onboard flight data processing unit, the first 5G frequency band communication unit, and the second 5G frequency band communication unit respectively. The onboard flight data processing unit is connected to the onboard dump unit and the first 5G frequency band communication unit respectively. The first 5G frequency band communication unit is connected to the second 5G frequency band communication unit. Among them, the first 5G frequency band communication unit is a dedicated communication unit, and the second 5G frequency band communication unit is a public communication unit.

[0048] The power management unit is used to receive an onboard 28V power supply and supply power to the onboard flight data processing unit, the first 5G frequency band communication unit, and the second 5G frequency band communication unit, respectively, to power the 5G terminal used for aviation flight tests. The power management unit may include anti-reverse connection, anti-surge, and voltage filtering module designs. The onboard flight data processing unit is used to obtain the first flight test data recorded by the aircraft during flight and transmit the first flight test data to the first 5G frequency band communication unit. The first flight test data includes second flight test data and third flight test data. The first 5G frequency band communication unit is used to split the first flight test data into second flight test data and third flight test data based on the data volume of the first flight test data, and transmit the second flight test data to the second 5G frequency band communication unit. The first 5G frequency band communication unit is also used to process the third flight test data and transmit the processed third flight test data to the ground control platform. The second 5G frequency band communication unit is used to process the second flight test data and transmit the processed second flight test data to the ground control platform.

[0049] Exemplarily, the 5G terminal for aviation flight testing is installed on an aircraft and may include an onboard flight data processing unit, a first 5G frequency band communication unit, and a second 5G frequency band communication unit. The onboard flight data processing unit may be a 10 Gigabit Ethernet onboard flight data processing unit, and the first 5G frequency band communication unit may be a 5G N79 communication unit, which can be used for high-bandwidth, low-latency scenarios such as rapid unloading of flight tests. The second 5G frequency band communication unit may be a 5G N41 communication unit, which can be used for low-latency, wide-internet of things scenarios such as remote support for maintenance, smart takeoff lines, and aircraft surface stress and damage inspections. It can also be understood that the first 5G frequency band communication unit is a dedicated communication unit, and the second 5G frequency band communication unit is a public communication unit. The onboard flight data processing unit is externally connected to the onboard dump unit on the aircraft, supports the 10 Gigabit Ethernet interface protocol, and internally supports the PCIE 1.0 / 2.0 / 3.0 interface protocol for service connection with the 5G N41 communication unit and the 5G N79 communication unit. It can serve as a local wired input and output channel for data transmission of 5G terminals used in aviation flight tests. The onboard flight data processing unit is internally connected to the first 5G frequency band communication unit. The first 5G frequency band communication unit is connected to the second 5G frequency band communication unit. The first 5G frequency band communication unit and the second 5G frequency band communication unit can provide a wireless network transmission channel for 5G terminals used in aviation flight tests. It can also be understood that the 5G N41 communication unit and the 5G N79 communication unit provide a wireless network transmission channel for 5G terminals used in aviation flight tests, support communication with mobile network operator infrastructure via the 3GPP Rel-15 radio protocol, support 5G SUB 6G N41 uplink dual-stream data transmission, and support 5G SA networking.

[0050] For example, the onboard flight data processing unit can obtain first flight test data recorded by the aircraft during flight and transmit the obtained first flight test data to the first 5G frequency band communication unit. The first flight test data may include test parameters of the avionics system, engine system, and airborne system throughout the flight test, monitoring status and control instructions of onboard sensors, recorders, switches, acquisition cards, transmitters, etc., fault characteristic parameters from aircraft maintenance inspections, and surface stress parameters of the entire aircraft. After receiving the first flight test data from the onboard flight data processing unit, the first 5G frequency band communication unit can divert the first flight test data according to the dynamic data volume allocation mechanism of gradient acceleration. First, the allocation vectors corresponding to the first flight test data of the first 5G frequency band communication unit and the second 5G frequency band communication unit are determined respectively. The allocation vector ratio of the first 5G frequency band communication unit and the second 5G frequency band communication unit is obtained based on the allocation vectors. Then, the first flight test data is split into second flight test data and third flight test data based on the allocation vector ratio, and the second flight test data is transmitted to the second 5G frequency band communication unit. The second flight test data may include test parameters of the avionics system, engine system, and airborne system during the entire flight test process in the first flight test data. The first 5G frequency band communication unit may also process the third flight test data and transmit the processed third flight test data to the ground control platform. The third flight test data may include monitoring status and control instructions of airborne sensors, recorders, switches, acquisition cards, transmitters, etc. in the first flight test data, fault characteristic parameters of aircraft maintenance inspection, and surface stress parameters of the entire aircraft. The second 5G frequency band communication unit may process the second flight test data and transmit the processed second flight test data to the ground control platform.

By adopting a dual-module structure consisting of a first 5G frequency band communication unit and a second 5G frequency band communication unit, the processing time of flight test data is reduced, significantly improving the transmission rate of large-capacity flight test data, thereby enhancing flight test efficiency. Furthermore, each 5G communication unit can be designed with two physical air interface links, ultimately achieving a four-way physical air interface link connection between onboard flight test data and the ground control platform. Compared to a single air interface link connection, this greatly improves the actual service carrying capacity of 5G terminals used in aviation flight tests.

[0052] In some embodiments, such as Figure 1 As shown, the above-mentioned first 5G frequency band communication unit includes: a first communication power management module, a first communication processor, a first RF transceiver, a first RF front-end circuit, and a first airborne 5G antenna.

The received flight test data can be processed and sent to the ground control platform. At the same time, by designing two physical air interface links for each 5G communication unit, it is ultimately possible to achieve a physical air interface link connection between four airborne test data channels and the ground control platform. Compared to a single air interface link connection, this greatly enhances the actual service carrying capacity of 5G terminals used in aviation flight tests and further improves the efficiency of processing and transmitting flight test data.

[0056] In some embodiments, the first communication processor is specifically used to: calculate the theoretical transmission rate ratio of the first 5G frequency band communication unit and the second 5G frequency band communication unit based on the total data packet capacity M of the first flight test data and the uplink time slot ratio of the first 5G frequency band communication unit and the second 5G frequency band communication unit; determine the allocation vector ratio according to the theoretical transmission rate ratio, and divert the first flight test data into the second flight test data and the third flight test data according to the allocation vector ratio.

[0057] Exemplarily, the first 5G band communication unit can control the second 5G band communication unit to obtain the channel and link management of the onboard dump unit flight test data from the onboard flight data processing unit. The first 5G band communication unit can control the second 5G band communication unit to turn on, off, and reset, and query the working status of the second 5G band communication unit. When the first 5G band communication unit detects that the data transmission of the second 5G band communication unit is abnormal, it can restore the normal operation of the second 5G band communication unit by controlling the first 5G band communication unit to turn on, off, and reset. The first 5G band communication unit can also calculate the theoretical transmission rate ratio of the first 5G band communication unit and the second 5G band communication unit based on the total data packet capacity M of the first flight test data and the uplink time slot ratio of the first 5G band communication unit and the second 5G band communication unit, and then determine the allocation vector ratio based on the theoretical transmission rate ratio, and divide the first flight test data into the second flight test data and the third flight test data according to the allocation vector ratio. The first 5G band communication unit can also detect whether the second flight test data has been transmitted to the second 5G band communication unit.

[0058] For example, when the total data packet capacity M is obtained based on the first flight test data, and the theoretical transmission rate ratio is calculated as 750Mbps:250Mbps based on the uplink time slot ratio of the first communication unit and the second communication unit, the allocation vector ratio can be determined to be 3:1 based on the theoretical transmission rate ratio, and the first flight test data can be divided into the second flight test data and the third flight test data at a ratio of 3:1.

[0059] This embodiment defines a first communication processor specifically configured to calculate the theoretical transmission rate ratio between the first 5G band communication unit and the second 5G band communication unit based on the total data packet capacity M of the first flight test data and the uplink time slot ratio between the first 5G band communication unit and the second 5G band communication unit; determine an allocation vector ratio based on the theoretical transmission rate ratio; and split the first flight test data into the second flight test data and the third flight test data based on the allocation vector ratio. This can further improve the data transmission rate.

[0060] In some embodiments, the first communication processor is further used to obtain the actual transmission rates of the first 5G frequency band communication unit and the second 5G frequency band communication unit within a preset period; determine the actual transmission rate ratio of the first 5G frequency band communication unit and the second 5G frequency band communication unit based on the actual transmission rate; and update the allocation vector ratio corresponding to the second flight test data and the third flight test data based on the actual transmission rate ratio.

[0061] Exemplarily, polling sampling can be performed according to a preset period T to obtain the actual transmission rates v1 and v2 of the first 5G frequency band communication unit and the second 5G frequency band communication unit, and then the updated allocation ratio vector v1 / v2 is calculated at time T. The ratio of the second flight test data and the third flight test data can be dynamically adjusted according to the ratio of v1 / v2 until the transmission of the first flight test data is completed.

[0062] This embodiment limits the first communication processor and is also used to obtain the actual transmission rates of the first 5G frequency band communication unit and the second 5G frequency band communication unit within a preset period; determine the actual transmission rate ratio of the first 5G frequency band communication unit and the second 5G frequency band communication unit according to the actual transmission rate; update the allocation vector ratio corresponding to the second flight test data and the third flight test data according to the actual transmission rate ratio, which can ensure the continuity of data transmission between the first 5G frequency band communication unit and the second 5G frequency band communication unit, avoid the first 5G frequency band communication unit or the second 5G frequency band communication unit being idle, and further improve the efficiency of data transmission.

[0063] In some embodiments, the first communication processor is further configured to monitor a transmission status of the third flight test data and store a transmission log of the third flight test data.

[0064] Exemplarily, the first communication processor can monitor the transmission status of the third flight test data, such as monitoring whether the transmission rate of the third flight test data meets the preset standards, monitoring whether the various modules used to process the third flight test data are operating normally, and at the same time, can also store the transmission log of the third flight test data.

[0065] This embodiment limits the first communication processor to monitor the transmission status of the third flight test data and store the transmission log of the third flight test data. This ensures that the transmission log can be queried when a fault occurs to quickly locate the cause and location of the fault, ensure the normal transmission of the flight test data, and reduce the impact of equipment failure on data transmission.

[0066] In some embodiments, the second 5G frequency band communication unit includes: a second communication power management module, a second communication processor, a second RF transceiver, a second RF front-end circuit, and a second airborne 5G antenna.

[0067] The second communication power management module is respectively connected to the power management unit, the second communication processor, the second RF transceiver, and the second RF front-end circuit. The second communication processor is connected to the second RF transceiver, the second RF transceiver is connected to the second RF front-end circuit, and the second RF front-end circuit is connected to the second airborne 5G antenna. The second communication power management module respectively supplies power to the second communication processor, the second RF transceiver, and the second RF front-end circuit to power the second 5G frequency band communication unit. The second communication processor is used to digitally modulate the second flight test data and transmit the processed second flight test data to the second RF transceiver. The second RF transceiver is used to perform digital-to-analog conversion and frequency shift modulation on the second flight test data processed by the second communication processor. The second RF front-end circuit is used to power amplify the third flight test data processed by the second RF transceiver and transmit the processed second flight test data to the ground control platform via the second airborne 5G antenna.

[0068] Exemplarily, the second 5G frequency band communication unit may be a 5G N41 communication unit, which may include a first communication power management module, a second communication processor, a second radio frequency transceiver (RF transceiver), a second RF front-end circuit, and a second airborne 5G antenna. The second communication power management module may be a second 5G communication power management module, the second communication processor may be a second 5G communication processor, the second RF transceiver may be a second 5G communication RF transceiver, the second RF front-end circuit may be a second 5G communication RF front-end circuit, and the second airborne 5G antenna may be a 4.9G antenna, which may include two 4.9G antennas. The specific processing method of the second 5G frequency band communication unit for the second flight test data can refer to the processing method of the first 5G frequency band communication unit for the third flight test data and is not further described here.

[0069] This embodiment defines a second 5G frequency band communication unit as comprising a second communication power management module, a second communication processor, a second RF transceiver, a second RF front-end circuit, and a second airborne 5G antenna. The second communication power management module is respectively connected to the power management unit, the second communication processor, the second RF transceiver, and the second RF front-end circuit. The second communication processor is connected to the second RF transceiver, the second RF transceiver is connected to the second RF front-end circuit, and the second RF front-end circuit is connected to the second airborne 5G antenna. The second communication power management module supplies power to the second communication processor, the second RF transceiver, and the second RF front-end circuit to power the second 5G frequency band communication unit. The second communication processor is configured to digitally modulate the second flight test data and transmit the processed second flight test data to the second RF transceiver. The second RF transceiver is configured to perform digital-to-analog conversion and frequency shift modulation on the second flight test data processed by the second communication processor. The second RF front-end circuit is configured to power amplify the third flight test data processed by the second RF transceiver and transmit the processed second flight test data to a ground control platform via the second airborne 5G antenna. The received flight test data can be processed and sent to the ground control platform. At the same time, by designing two physical air interface link connections for each 5G communication unit, it is ultimately possible to achieve a physical air interface link connection between four-way airborne test data and the ground control platform. Compared with a single-way air interface link connection, this greatly improves the actual business carrying capacity of 5G terminals used in aviation flight tests, and further improves the efficiency of processing and transmitting flight test data.

[0070] In some embodiments, the second communication processor is further configured to monitor a transmission status of the second flight test data and store a transmission log of the second flight test data.

[0071] For example, the specific manner in which the second communication processor monitors the transmission status of the second flight test data and stores the transmission log of the second flight test data can refer to the specific manner in which the first communication processor monitors the transmission status of the third flight test data and stores the transmission log of the third flight test data, which will not be repeated here.

[0072] This embodiment limits the second communication processor to monitor the transmission status of the second flight test data and store the transmission log of the second flight test data. This ensures that the transmission log can be queried when a fault occurs to quickly locate the cause and location of the fault, ensure the normal transmission of the flight test data, and reduce the impact of equipment failure on data transmission.

[0073] In an exemplary embodiment, the present disclosure also provides an airborne data transmission method, which can be applied to the above-mentioned 5G terminal for aviation flight testing.

[0074] For example, the execution entity of the airborne data transmission method may be a computer or server, or other devices with data processing capabilities (for example, a 5G terminal for aviation flight testing), or a data processing chip or data processor on aircraft equipment. The execution entity of this method is not limited herein.

[0075] Figure 2 Schematic diagram of the flow of the airborne data transmission method provided by the embodiment of the present disclosure. Figure 2 As shown, the method may include S201-S204.

[0076] S201. Acquire first flight test data recorded by an aircraft during flight through an onboard flight data processing unit, and transmit the first flight test data to a first 5G frequency band communication unit connected to the onboard flight data processing unit.

[0077] The first flight test data includes the second flight test data and the third flight test data.

[0078] S202. Acquire first flight test data through the first 5G frequency band communication unit, and determine the allocation vectors of the first 5G frequency band communication unit and the second 5G frequency band communication unit corresponding to the first flight test data according to the dynamic data volume allocation mechanism of gradient acceleration, obtain the allocation vector ratio of the first 5G frequency band communication unit and the second 5G frequency band communication unit, split the first flight test data into second flight test data and third flight test data according to the allocation vector ratio, and transmit the second flight test data to the second 5G frequency band communication unit.

[0079] S203. Process the third flight test data through the first 5G frequency band communication unit, and transmit the processed third flight test data to the ground control platform.

[0080] S204. Process the second flight test data through the second 5G frequency band communication unit, and transmit the processed second flight test data to the ground control platform.

[0081] For example, a design can combine carrier aggregation (CA) technology, multi-antenna MIMO technology, and multi-level modulation technology to achieve high-speed, high-bandwidth, and interference-resistant transmission. The carrier aggregation bandwidth is designed to be 400MHz, supporting a maximum of four carriers: two N41 carriers and two N79 carriers. A dual-stream uplink and downlink (2x2 MIMO) system is designed, with the first airborne 5G antenna supporting both the N41 and N79 frequency bands. The multi-level modulation scheme can include uplink and downlink modulation, including 16QAM, 64QAM, and 256QAM. For example, a 5G terminal in aviation flight testing transmits flight test data from an airborne dump unit to a ground control platform. This flight test data can include network packet data, bus data, and optical fiber data. The 5G terminal used in aviation flight tests obtains flight test data from the airborne dump unit through the 10 Gigabit Ethernet port of the onboard flight data processing unit, and distributes the diverted data to 5G communication processor 1 and 5G communication processor 2 through the PCIE3.0 port. The 5G communication processor digitally modulates the data stream and sends it to the 5G communication RF transceiver. The 5G communication RF transceiver converts the data stream into digital-to-analog and then performs frequency shift modulation. The modulated analog signal is sent to the 5G communication RF front-end circuit for power amplification and finally sent to the ground control platform through the antenna, completing the transmission of airborne wired data through the 5G SUB6G air interface link, realizing high-speed transmission of large-capacity test data.

[0082] In this embodiment, the onboard flight data processing unit obtains first flight test data recorded by the aircraft during flight, and transmits the first flight test data to a first 5G frequency band communication unit connected to the onboard flight data processing unit. The first flight test data is then split into second flight test data and third flight test data by the first 5G frequency band communication unit according to a dynamic data volume allocation mechanism of gradient acceleration, and the second flight test data is transmitted to a second 5G frequency band communication unit connected to the first 5G frequency band communication unit. Finally, the third flight test data is processed by the first 5G frequency band communication unit and the processed third flight test data is transmitted to the ground control platform. The second flight test data is processed by the second 5G frequency band communication unit and the processed second flight test data is transmitted to the ground control platform. By adopting a dual-module structure of the first 5G frequency band communication unit and the second 5G frequency band communication unit, the time for processing flight test data is reduced, the transmission rate of large-capacity flight test data is greatly improved, and the efficiency of flight testing is improved. At the same time, each 5G communication unit can be designed with two physical air interface link connections, ultimately realizing the physical air interface link connection between four-way airborne flight test data and the ground control platform. Compared with a single air interface link connection, it greatly improves the actual business carrying capacity of 5G terminals used in aviation flight tests.

[0093] For example, Figure 3For the processing process of the third flight test data by the first 5G frequency band communication unit, the specific implementation method and beneficial effects can be referred to the above description of the first 5G frequency band communication unit, which will not be repeated here. Figure 4 For the processing process of the second flight test data by the second 5G frequency band communication unit, the specific implementation method and beneficial effects can be referred to the above description of the second 5G frequency band communication unit, which will not be repeated here.

[0094] In an exemplary embodiment, the present disclosure further provides an airborne data transmission system for implementing the above-mentioned airborne data transmission method.

[0095] Figure 5 This is a schematic diagram of the principle of the airborne data transmission system provided by the embodiment of the present disclosure. Figure 5 As shown, the system can include a 5G terminal for aviation flight testing, an airborne dump unit, and a ground control platform.

[0096] The onboard dump unit is connected to a 5G terminal for aviation flight testing. The onboard dump unit is used to send flight test data to the 5G terminal for aviation flight testing. The 5G terminal for aviation flight testing is used to receive flight test data sent by the onboard dump unit and send the flight test data to the ground control platform. The ground control platform is used to receive flight test data sent by the 5G terminal for aviation flight testing. The 5G terminal for aviation flight testing and the onboard dump unit are connected via optical fiber.

[0097] For example, after the 5G terminal for aviation flight testing obtains flight test data from the onboard dump unit, it processes the obtained flight test data and then sends the processed flight test data to the ground control platform. At the same time, the ground control platform can also transmit data to the 5G terminal for aviation flight testing and the onboard dump unit. The ground control platform can monitor the dumping and transmission of flight test data, the device status and service status of the 5G terminal for aviation flight testing, and when an abnormality occurs, the ground control platform can control the 5G terminal for aviation flight testing by sending control commands.

[0098] For example, assume that the 5G terminal for aviation flight testing on test aircraft A establishes a connection with a ground-based 5G base station after undergoing rapid network registration and access authentication. As the test aircraft lands on the runway and taxis, the 5G terminal quickly registers and requests access. After authentication and access through the ground-based 5G base station, the 5G terminal accesses test data from the onboard dump unit via the 10 Gigabit Ethernet port of the 10 Gigabit Ethernet processing unit. The offloaded data is then distributed via the PCIE 3.0 port to 5G communication processors 1 and 2, respectively. 5G communication processors 1 and 2 digitally modulate the data streams and send them to 5G communication RF transceivers 1 and 2. 5G communication RF transceivers 1 and 2 perform DA conversion and frequency shift modulation on the data streams. Finally, the modulated analog signal is sent to the 5G communication RF front-end circuit for power amplification and then transmitted via the antenna to the ground control platform, enabling high-speed transmission of large-capacity test data.

[0099] This embodiment proposes a data transmission system, which can include a 5G terminal for aviation flight testing, an airborne dump unit, and a ground control platform. The airborne dump unit is connected to the 5G terminal for aviation flight testing; the airborne dump unit is used to send flight test data to the 5G terminal for aviation flight testing; the 5G terminal for aviation flight testing is used to receive the flight test data sent by the airborne dump unit and send the flight test data to the ground control platform; the ground control platform is used to receive the flight test data sent by the 5G terminal for aviation flight testing. The airborne data transmission method can be implemented through the airborne data transmission system, and by designing the 5G SUB6G air interface link communication to comply with the 3GPP Rel-15 radio protocol to communicate with the mobile network operator infrastructure, the same ground control platform can be mounted with multiple 5G terminals for aviation flight testing for parallel data services, and under the same network topology, the ground network can simultaneously monitor and control the device status and service status of multiple 5G terminals for aviation flight testing, which is conducive to the intelligent and efficient transmission and management of test flight data.
