DETAILED DESCRIPTION

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] However, the current method of processing flight test data is time-consuming and affects the efficiency of flight tests.

[0037] 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. Taking the C919 large passenger aircraft test flight as an example, during the test flight, more than tens of thousands of parameters need to be collected, and each flight has about hundreds of gigabytes (GB) of test record data. The current processing method for flight test data is the "manual disk delivery-data unloading-post-processing" mode, that is, after the flight, the flight test data recorded by the onboard recorder is unloaded to the data server through professional unloading software and bit stream analysis is performed as needed, and then provided to the data processing personnel for data preprocessing and secondary processing. However, the current processing method of flight test data will cause long data unloading processing time, restrict the timeliness of data acquisition in the subject, and affect the efficiency of flight tests.

[0038] 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.

[0039] 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.

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 the flight, and transmit the first flight test data to the first 5G frequency band communication unit.

The second 5G frequency band communication unit may be a 5G N41 communication unit, which may 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 inspection. 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 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, and the first 5G frequency band communication unit and the second 5G frequency band communication unit can provide a wireless network transmission channel for the 5G terminal for aviation flight tests.

The first RF front-end circuit is used to perform power amplification processing on the third flight test data processed by the first RF transceiver, and transmit the processed third flight test data to the ground control platform through the 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 link connections for each 5G communication unit, the physical air interface link connection between the four airborne test data and the ground control platform can be finally realized. Compared with the single air interface link connection, the actual business carrying capacity of the 5G terminal for aviation flight test is greatly improved, and the efficiency of processing and transmitting flight test data is further improved.

[0050] 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.

[0051] Exemplarily, the first 5G band communication unit can control the second 5G band communication unit to obtain the channel and link management of the flight test data of the airborne dump unit from the airborne flight data processing unit. The first 5G band communication unit can control the second 5G band communication unit to turn on, turn off and reset, query the working status of the second 5G band communication unit, and when the first 5G band communication unit detects that the data transmission of the second 5G band communication unit is abnormal, the second 5G band communication unit can be restored to normal operation by controlling the first 5G band communication unit to turn on, turn 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 according to the total data packet capacity M of the first flight test data, 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 according to 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 is transmitted to the second 5G band communication unit.

[0052] For example, when the total data packet capacity M is obtained according to 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 according to 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.

[0053] This embodiment defines the first communication processor, which is specifically used to calculate the theoretical transmission rate ratio of the first 5G band communication unit and the second 5G band communication unit according to 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; determine the allocation vector ratio according to 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 rate of data transmission can be further improved.

[0054] In some embodiments, the first communication processor is also used to obtain 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; and 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.

[0055] 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 to 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.

[0056] 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.

[0057] In some embodiments, the first communication processor is further used to monitor the transmission status of the third flight test data and store a transmission log of the third flight test data.

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 channels of airborne 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, and further improves the efficiency of processing and transmitting flight test data.

[0064] In some embodiments, the second communication processor is further used to monitor the transmission status of the second flight test data and store a transmission log of the second flight test data.

[0065] Exemplarily, 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.

[0074] 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.

[0075] For example, the combined use of carrier aggregation CA technology, multi-antenna MIMO technology and multi-order modulation technology and technological breakthroughs can be designed to achieve high-speed, high-bandwidth anti-interference transmission. The carrier aggregation bandwidth is designed to be 400MHz, and the maximum number of carriers supported is 4, which are 2 N41 carriers and 2 N79 carriers. Design uplink and downlink dual streams (2*2 MIMO), including the first airborne 5G antenna is an airborne 5G antenna with two frequency bands of N41 and N79, and the first airborne 5G antenna is an airborne 5G antenna with two frequency bands of N41 and N79.

Take the example of a 5G terminal for aviation flight test sending flight test data of an airborne dump unit to a ground control platform, where the flight test data can include network packet data, bus data, and optical fiber data. The 5G terminal used in aviation flight tests obtains the flight test data of the airborne dump unit through the 10 Gigabit Ethernet port of the airborne 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 the airborne wired data through the 5G SUB6G air interface link, realizing high-speed transmission of large-capacity test data.

[0076] In this embodiment, the first flight test data recorded by the aircraft during the flight is obtained by the airborne flight data processing unit, and the first flight test data is transmitted to the first 5G frequency band communication unit connected to the airborne flight data processing unit, and then the first flight test data is divided into the second flight test data and the third flight test data by the first 5G frequency band communication unit according to the dynamic data volume allocation mechanism of gradient acceleration, and the second flight test data is transmitted to the second 5G frequency band communication unit connected to the first 5G frequency band communication unit, and 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, and 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.

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 channels of 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.

[0088] In an exemplary embodiment, the present disclosure also provides an airborne data transmission system for implementing the above-mentioned airborne data transmission method.

[0089] Figure 5 The schematic diagram of the principle of the airborne data transmission system provided by the embodiment of the present disclosure is as follows. Figure 5 As shown, the system may include a 5G terminal for aviation flight testing, an airborne dump unit, and a ground control platform.

Among them, the 5G terminal for aviation flight test is connected to the airborne dump unit through optical fiber.

[0091] For example, after the 5G terminal for aviation flight test obtains the flight test data from the airborne 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 test and the airborne dump unit. The ground control platform can monitor the dumping and transmission of flight test data, the equipment status and service status of the 5G terminal for aviation flight test. When an abnormality occurs, the ground control platform can control the 5G terminal for aviation flight test by sending control instructions.

[0092] For example, assume that the 5G terminal for aviation flight test of test aircraft A establishes a connection with the ground 5G base station after rapid network registration and access authentication. When the test aircraft lands on the runway and taxis, the 5G terminal for aviation flight test quickly registers the network and requests access; after the ground 5G base station is authenticated and accessed, the 5G terminal for aviation flight test obtains the test data of the airborne dump unit through the 10G network port of the 10G Ethernet processing unit; then distributes the diverted data to 5G communication processor 1 and 5G communication processor 2 respectively through the PCIE3.0 port, and 5G communication processors 1 and 2 digitally modulate the data stream and send it 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 stream; finally, the modulated analog signal is sent to the 5G communication RF front-end circuit for power amplification, and sent to the ground control platform through the antenna, realizing high-speed transmission of large-capacity test data.

[0093] This embodiment proposes a data transmission system, which can include a 5G terminal for aviation flight test, an airborne dump unit and a ground control platform. The airborne dump unit is connected to the 5G terminal for aviation flight test; the airborne dump unit is used to send flight test data to the 5G terminal for aviation flight test; the 5G terminal for aviation flight test 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 test. The airborne data transmission method can be implemented through the airborne data transmission system, and by designing the air interface link communication of 5G SUB6G to comply with the 3GPP Rel-15 radio protocol and communicate with the mobile network operator infrastructure, the same ground control platform can be mounted with multiple 5G terminals for aviation flight test. Parallel services of data services, and under the same network topology, the ground network can simultaneously monitor and control the equipment status and service status of multiple 5G terminals for aviation flight test, which is conducive to the intelligent and efficient transmission and management of test flight data.
