[0002] Airborne Ka systems based on Ka / Ku airborne phased array antennas that integrate high and low orbits, or other satellite navigation and communication systems such as BeiDou, support different data transmission modes depending on the access conditions of different orbital satellites and channels. Different orbital satellites include those operating at different altitudes (high, medium, and low Earth orbits), and channels include those with and without rain attenuation, such as data stream mode, long field transmission length limited mode, and short field transmission length limited mode. Data stream mode is used when the link quality is good and can be used to transmit audio, video, and large files. Long field transmission length limited mode can be used for data transmission of longer bytes. Short field transmission length limited mode can be used for data transmission of shorter bytes.

[0003] Therefore, how to design the internal transmission mode of airborne equipment according to the channel environment and communication protocol working mode in order to efficiently support various avionics access equipment is a technical problem that technical personnel in this field need to solve.

[0025] If the airborne equipment is selecting the optimal data transmission mode for the first time, and if the current signal-to-noise ratio (SNR) is less than a first threshold, then the optimal data transmission mode is a long field transmission length restriction mode; if the current SNR is less than a second threshold, then the optimal data transmission mode is a short field transmission length restriction mode; if the current SNR is greater than or equal to the first threshold and / or the current SNR is greater than or equal to the second threshold, then the optimal data transmission mode is a data stream mode.

[0042] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] The terms "first," "second," "third," "fourth," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may include steps or units not listed.

[0044] After introducing the technical solutions of the embodiments of the present invention, the various non-limiting embodiments of this application will be described in detail below.

[0045] First see Figure 1 , Figure 1 This is a flowchart illustrating an airborne data information transmission method according to an embodiment of the present invention. The embodiment of the present invention may include the following:

[0046] S101: When the airborne avionics access signal is detected, obtain the transmission data information of the device to be accessed.

[0047] In this embodiment, the airborne avionics access signal is used to identify whether a device needs to be connected to the airborne equipment. For ease of description, the device that needs to be connected to the airborne equipment is referred to as the device to be connected. The transmitted data information includes all data and signals sent by the device to be connected to the airborne equipment. The transmitted data information includes the data to be transmitted and the data transmission mode required by the device to be connected; the transmitted data is the data sent by the device to be connected to the airborne equipment. The device to be connected and the airborne equipment can be connected via any of the following methods: wired Ethernet, WiFi, and Bluetooth.

[0048] S102: Determine the optimal data transmission mode currently supported by the airborne equipment based on the link quality test results.

[0049] The optimal data transmission mode in this embodiment refers to the data transmission mode supported by the airborne equipment under the current communication link. This is called the optimal data transmission mode. The data transmission mode can be a data stream mode, a long field transmission length limit mode, or a short field transmission length limit mode.

[0050] S103: Determine the transmission mode negotiation result based on the transmitted data information and the optimal data transmission mode, and feed back the transmission mode negotiation result to the device to be connected.

[0051] In this embodiment, the transmission mode negotiation result can be fed back in the form of preset rules. The transmission mode negotiation result can indicate the data transmission mode supported by the current airborne device and whether the data transmission mode supported by the current airborne device is the same as the data transmission mode supported by the device to be accessed. Those skilled in the art can flexibly choose according to the actual application scenario, which will not affect the implementation of this application. For example, if the optimal data transmission mode is the data stream mode, and the data transmission mode required by the device to be accessed is the data stream mode, then the number 1 is sent to the device to be accessed; if the data transmission mode required by the device to be accessed is the long field transmission length restriction mode, then the number 2 is sent to the device to be accessed. If the optimal data transmission mode is the long field transmission length restriction mode, and the data transmission mode required by the device to be accessed is the data stream mode, then the number 0 is sent to the device to be accessed; if the data transmission mode required by the device to be accessed is the long field transmission length restriction mode, then the number 1 is sent to the device to be accessed. The optimal data transmission mode is the short field transmission length limit mode. If the data transmission mode required by the device to be accessed is the data stream mode, then send the number 0 to the device to be accessed; if the data transmission mode required by the device to be accessed is the long field transmission length limit mode, then send the number 0 to the device to be accessed.

[0052] S104: Transmit the data to be accessed from the device using the data transmission mode corresponding to the data transmission mode negotiation result.

[0053] After determining the data transmission mode for the devices to be connected in the previous step, the corresponding data transmission mode implementation module is invoked to process the transmitted data. Furthermore, to facilitate sending the transmitted data to any target device, the transmitted data can be frequency-converted to obtain the corresponding base station signal or intermediate frequency signal.

[0054] In the technical solution provided by the embodiments of the present invention, the final data transmission mode is determined by the optimal data transmission mode supported by the current airborne equipment and the target data transmission mode required by the device to be accessed by the airborne equipment. This provides an internal transmission mode for airborne equipment that takes into account both the receiving link quality of the entire airborne equipment and the user's needs, thereby efficiently supporting various avionics access devices, improving the practicality of airborne equipment, and improving the user's data transmission efficiency.

[0055] It should be noted that there is no strict order of execution for the steps in this application. As long as they conform to a logical order, these steps can be executed simultaneously or in a certain preset order. Figure 1This is just an illustrative example and does not mean that this is the only possible execution order.

[0056] In the above embodiments, there is no limitation on how to perform step S103. This embodiment provides two parallel optional implementation methods, which may include the following steps:

[0057] If the transmitted data information includes data packets and emergency signals, the transmitted data and emergency signals of the device to be accessed are obtained by parsing the transmitted data information; the data transmission mode corresponding to the emergency signal is used as the result of the transmission mode negotiation. In this embodiment, the data transmission mode used for the emergency signal is specified in advance. When the emergency signal of the device to be accessed is received, the corresponding data transmission mode is directly used for data transmission, without being limited by the current communication link.

[0058] If the transmitted data information includes transmission data packets and transmission mode data packets, the transmission data to be accessed and the required target data transmission mode of the device are obtained by parsing the transmission data information; the transmission mode negotiation result is determined based on the target data transmission mode and the optimal data transmission mode.

[0059] This application provides different data transmission mode selection methods for different application scenarios, making airborne equipment more practical and improving the user experience.

[0060] The above embodiments do not limit how step S102 is performed. This embodiment provides two parallel optional implementation methods, which may include the following steps:

[0061] Optionally, as an alternative implementation method, the satellite network mode output by the currently accessed satellite link can be obtained; the data transmission mode adopted by the satellite network mode can be taken as the optimal data transmission mode.

[0062] As another implementation method parallel to the above embodiments, the current signal-to-noise ratio (SNR) and various preset threshold values ​​can also be obtained; it can be determined whether the airborne device is selecting the optimal data transmission mode for the first time; if the airborne device is selecting the optimal data transmission mode for the first time, and if the current SNR value is less than the first threshold value, then the optimal data transmission mode is the long field transmission length restriction mode; if the current SNR value is less than the second threshold value, then the optimal data transmission mode is the short field transmission length restriction mode; if the current SNR value is greater than or equal to the first threshold value and / or the second threshold value, then the optimal data transmission mode is the data stream mode; if the airborne device is not selecting the optimal data transmission mode for the first time, and if the current SNR value is less than the first threshold value or greater than the corrected second threshold value, then the optimal data transmission mode is the long field transmission length restriction mode; if the current SNR value is greater than the corrected first threshold value, then the optimal data transmission mode is the data stream mode; if the current SNR value is less than the second threshold value, then the optimal data transmission mode is the short field transmission length restriction mode.

[0063] In this embodiment, the optimal data transmission mode can be determined based on the output of the receive link quality detection module. The receive link quality detection module selects the satellite network mode based on the current access satellite link output. For example, the satellite network itself may be operating in three modes: data stream mode, long field transmission length limitation mode, and short field transmission length limitation mode. Of course, some satellite networks may not support data stream mode. The receive link quality detection module selects different modes based on the received signal-to-noise ratio (SNR) R: Initial selection: If R is below the threshold AdB, long field transmission length limitation mode is selected; if R is below the threshold BdB, short field transmission length limitation mode is selected; otherwise, data stream mode is selected. Non-initial selection: If R is below the threshold AdB, long field transmission length limitation mode is selected; if R is above A+a dB (a is a correction value, such as 1), data stream mode is selected; if R is below the threshold BdB, short field transmission length limitation mode is selected; if R is above B+a dB (a is a correction value), long field transmission length limitation mode is selected.

[0064] This application provides multiple methods for determining the optimal data transmission mode, making airborne equipment more practical and improving the user experience.

[0065] This invention also provides a corresponding apparatus for the airborne data transmission method, further enhancing the practicality of the method.

[0069] The transmission module 203 is used to transmit the data to be accessed from the device using the data transmission mode corresponding to the result of the transmission mode negotiation.

[0074] As another optional implementation method parallel to the above embodiments, the optimal mode determination unit may further be used to: obtain the current signal-to-noise ratio and each preset threshold; determine whether the airborne device is selecting the optimal data transmission mode for the first time; if the airborne device is selecting the optimal data transmission mode for the first time, and if the current signal-to-noise ratio value is less than the first threshold, then the optimal data transmission mode is the long field transmission length restriction mode; if the current signal-to-noise ratio value is less than the second threshold, then the optimal data transmission mode is the short field transmission length restriction mode; if the current signal-to-noise ratio value is greater than or equal to the first threshold and / or the second threshold, then the optimal data transmission mode is the data stream mode; if the airborne device is not selecting the optimal data transmission mode for the first time, and if the current signal-to-noise ratio value is less than the first threshold or greater than the corrected second threshold, then the optimal data transmission mode is the long field transmission length restriction mode; if the current signal-to-noise ratio value is greater than the corrected first threshold, then the optimal data transmission mode is the data stream mode; if the current signal-to-noise ratio value is less than the second threshold, then the optimal data transmission mode is the short field transmission length restriction mode.

[0082] The functions of each functional module of the electronic device in the embodiments of the present invention can be specifically implemented according to the methods in the above method embodiments. The specific implementation process can be referred to the relevant descriptions in the above method embodiments, which will not be repeated here.

[0083] As can be seen from the above, the embodiments of the present invention can efficiently support various avionics access devices.

[0084] It is understood that if the airborne data transmission method in the above embodiments is implemented as a software functional unit and sold or used as an independent product, it can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this application, in essence, or the part that contributes to the prior art, or all or part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and executes all or part of the steps of the methods in the various embodiments of this application. The aforementioned storage medium includes: USB flash drive, mobile hard drive, read-only memory (ROM), random access memory (RAM), electrically erasable programmable ROM, register, hard disk, multimedia card, card-type memory (e.g., SD or DX memory), magnetic memory, removable disk, CD-ROM, magnetic disk or optical disk, and other media capable of storing program code.

[0085] Based on this, embodiments of the present invention also provide a readable storage medium storing a computer program, wherein when the computer program is executed by a processor, the steps of the airborne data information transmission method of any of the above embodiments are as follows.

[0086] This invention also provides an airborne data information transmission system, please refer to [link / reference]. Figure 4 It may include:

[0087] The airborne data transmission system may include airborne equipment 41 and avionics access equipment 42. Avionics access equipment 42 is an airborne avionics access device, such as a tablet computer, cabin server, or any other device that connects to airborne equipment 41. Avionics access equipment 42 and airborne equipment 41 can be connected wirelessly or via wired connection, which does not affect the implementation of this application.

[0088] The airborne equipment includes an avionics access switching device, an avionics handshake processing module, a transmit data processing mode selection module, an optimal operating mode determination module, a receive link quality detection module, and a data transmission module. The avionics access switching device monitors whether the access port of the device has an airborne avionics access signal; it supports wired Ethernet, WiFi, and Bluetooth transmission. The avionics handshake processing module determines the transmission mode negotiation result based on the optimal data transmission mode sent by the optimal operating mode determination module and the transmission data information of the avionics access device, and sets an operating mode value that identifies the transmission mode negotiation result; it also feeds back the transmission mode negotiation result to the avionics access device. In other words, the avionics handshake processing module is used to negotiate the data transmission mode with the avionics access device. The transmit data processing mode selection module selects the appropriate data transmission module based on the operating mode value and the optimal operating mode to transmit the data transmitted by the avionics access device. The data transmission module includes a data stream mode processing module, a long field transmission length limitation mode processing module, and a short field transmission length limitation mode processing module. The long field transmission length limitation mode processing module supports packet transmission. The link quality detection module generates a link quality detection result based on the communication link information fed back by the receiving antenna. The optimal operating mode decision module is used to determine the optimal data transmission mode currently supported by the airborne equipment based on the link quality detection results output by the receive link quality detection module.

[0089] Furthermore, to improve the practicality of this system, the aforementioned device may also include a digital-to-intermediate radio frequency module, used to realize the frequency conversion processing of digital to base station signals and intermediate radio frequency, thereby sending the frequency-converted signal to the antenna for transmission outward through the antenna.

[0090] To enable those skilled in the art to more clearly understand the technical solution of this application, this application also incorporates... Figure 5 An illustrative example is provided, taking a tablet computer as the avionics access device and WiFi access as the avionics access adapter. Correspondingly, the airborne equipment is the airborne wireless transmission equipment, which may include the following:

[0091] When the airborne wireless transmission equipment is powered on, the avionics access adapter continuously monitors data on a specific WiFi port. The tablet sends two types of data packets: ordinary data packets, sent directly to the data transmission processing mode selection module; and handshake data packets, sent directly to the avionics handshake processing module. The avionics handshake processing module defaults to supporting the short-field transmission length restriction mode. This occurs when the tablet needs to send an emergency signal and the data is very short, eliminating the need for a handshake with the avionics handshake processing module; it directly sends ordinary data packets. The data transmission processing mode selection module reads the default value from the avionics handshake processing module and forwards the received ordinary data packets to the short-field transmission length restriction mode processing module for transmission. The short-field transmission length restriction mode processing module directly packages the data for transparent transmission. If the avionics handshake processing module receives a handshake data packet, it parses the desired transmission mode of the tablet. The processing method is as follows: the optimal working mode determination module outputs that the airborne wireless equipment supports data stream mode; if the tablet wants to support data stream mode, it sends the number 1 to the tablet; if the tablet wants to support long-field transmission length restriction mode, it sends the number 2 to the tablet. The optimal working mode determination module outputs that the airborne wireless equipment supports long-field transmission... In the transmission length limitation mode, if the tablet computer wants to support the data stream mode, it sends the number 0 to the tablet computer; if the tablet computer wants to support the long field transmission length limitation mode, it sends the number 1 to the tablet computer. The optimal operating mode decision module outputs that the airborne radio device supports the short field transmission length limitation mode. If the tablet computer wants to support the data stream mode, it sends the number 0 to the tablet computer; if the tablet computer wants to support the long field transmission length limitation mode, it sends the number 0 to the tablet computer. The data processing mode selection module reads the operating mode value of the avionics equipment handshake processing module and selects the data stream mode processing module, the long field transmission length limitation mode processing module, or the short field transmission length limitation mode processing module for data transmission.
