[0032] like Figure 2 As shown, the embodiment of the present invention provides an airborne terminal air-to-ground automated data rapid and secure transmission system, including the following program modules:

[0033] Air-ground communication link establishment module 101: The air-ground communication link establishment module 101 is used to detect the air-ground status of the air-ground communication equipment on the aircraft. When the aircraft is on the ground, the air-ground communication preset configuration is loaded to establish a physical and logical link with the airline operation system (i.e., the ground operation system).

[0034] Air-ground communication link security detection module 102: The air-ground communication link security detection module 102 is used to detect the security of the established physical and logical links, and perform security checks on the link status, link protocol and link data content. When the link status, link protocol and link data content exceed the safety switch threshold within a certain duration, the air-ground communication link disconnection module is called to close the logical link and physical link, shut down the equipment operation, and ensure that the data transmission link is always safe.

[0035] Aircraft information registration module 103: The aircraft information registration module 103 transmits aircraft information to the airline operating system through the physical link and logical link established by the air-ground communication link establishment module, indicating to the airline operating system which route the aircraft to which the data is transmitted is operating (i.e., the aircraft's unique identity information), so that the airline operating system can conduct data operation analysis and reporting on this aircraft.

[0036] Air-ground data transmission handshake module 104: The air-ground data transmission handshake module 104 is used to provide the airline operation system with information on airborne data transmission and determine the type, size, transmission mechanism, verification method, etc. of the transmission data file.

[0037] Air-to-ground data transmission module 105: The air-to-ground data transmission module 105 is used to carry out data transmission with the airline operation system, and transmit the onboard data to the airline operation system quickly and safely.

[0038] The air-to-ground data transmission termination module 106 is used to indicate to the airline operation system that the airborne data transmission is completed or an abnormality has occurred and the transmission process needs to be terminated.

[0039] Air-to-ground communication link disconnection module 107: The air-to-ground communication link disconnection module 107 is used to disconnect the logical and physical links and shut down the equipment operation.

[0040] like Figure 1 As shown, the present invention also provides a method for rapid and safe transmission of air-to-ground automated data on an airborne end, comprising the following steps:

[0041] S101. Detect the air-ground status switch of the air-ground communication device on the aircraft. When the physical signal of the air-ground status switch is in the ground state, load the preset air-ground communication configuration and establish a communication link with the ground operation system. The communication link includes a physical link and a logical link.

[0042] S102. Acquire the unique identity information of the aircraft during operation from the airborne system, encapsulate the unique identity information of the aircraft into an aircraft registration message according to the airborne air-to-ground data transmission protocol, and send the aircraft registration message to the ground operation system;

[0043] S103. Obtain relevant information of the data file to be transmitted on the aircraft, and encapsulate the relevant information into an air-to-ground data transmission task command according to the airborne air-to-ground data transmission protocol, and send the air-to-ground data transmission task command to the ground operation system; wherein the relevant information includes the type, size, transmission mechanism and verification method of the data file;

[0044] S104. Transmitting the airborne data corresponding to the air-to-ground data transmission task command to the ground operation system; when the airborne data transmission is completed or a transmission abnormality occurs, sending a data termination command to the ground operation system to terminate the data transmission process;

[0045] S105. Disconnect the communication link and shut down the device operation.

[0046] In some embodiments, a method for rapid and secure airborne space-ground automated data transmission in this embodiment specifically includes the following steps:

[0047] 1.1. The air-ground communication link establishment module detects the physical signal of the air-ground status switch. When the physical signal of the air-ground switch is in the ground state, the air-ground communication link establishment module starts to work, starts the air-ground communication link physical interface, and establishes the physical link; the air-ground communication link establishment module detects the connectivity of the logical link with the airline operation system. If the logical link is not connected, it continues to detect and reports the logical link disconnection status to the air-ground communication link security detection module; if the logical link is connected, the air-ground communication link establishment module conducts a secure encrypted link negotiation with the airline operation system. After the negotiation is successful, it reports the air-ground communication link security status to the air-ground communication link security detection module. The detection module reports the availability status of the logical link; if the negotiation is unsuccessful, the negotiation continues and the encryption link unavailability status is reported to the air-ground communication link security detection module; when the encryption link negotiation is successful, the air-ground communication link establishment module conducts data transmission link negotiation with the airline operation system. After the negotiation is successful, the air-ground communication link establishment module reports the availability status of the data transmission link to the air-ground communication link security detection module, and the data transmission link can be used to start automatic data transmission between air and ground; if the negotiation is unsuccessful, the air-ground communication link establishment module reports the unavailability status of the data transmission link to the air-ground communication link security detection module.

[0048] 1.2. After the air-to-ground communication link establishment module in 1.1 establishes an available data transmission link, the aircraft information registration module starts to work. The aircraft information registration module obtains the aircraft's unique identity information during operation from the airborne system, and encapsulates the aircraft's unique identity information into an aircraft registration message according to the airborne air-to-ground data transmission protocol, and sends the message to the airline operation system; after receiving the aircraft registration message, the airline operation system returns the aircraft registration response information to the airborne air-to-ground automated data rapid and secure transmission system; after receiving the aircraft registration response message, the airborne air-to-ground automated data rapid and secure transmission system calls the air-to-ground communication link security detection module to perform a security check on the link and data content. If the security check passes, subsequent actions are allowed. If the security check fails, the link is started to be counted for security thresholds. When the link security threshold statistics (i.e., the number of detections within a set time period) exceeds the preset security threshold, the air-to-ground communication link disassembly module is called to work.

[0049] When the security check is passed and the aircraft registration response message indicates that the registration is successful, the data transmission handshake module starts working.

[0050] 1.3. The air-ground data transmission handshake module starts to work. The air-ground data transmission handshake module obtains the data file to be transmitted on the aircraft, and encapsulates it into an air-ground data transmission task command according to the airborne air-ground data transmission protocol, and sends the air-ground data transmission task command to the airline operation system; after the airline operation system receives the air-ground data transmission task command, it parses the air-ground data transmission task command according to the airborne air-ground data transmission protocol, and returns the air-ground data transmission task response command to the aircraft. When the aircraft receives the air-ground data transmission task response command, the air-ground communication link security detection module is called to perform a security check on the link and data content. If the security check passes, subsequent actions are allowed. If the security check fails, the link is started to perform security threshold statistics. When the link security threshold statistics exceed the preset security threshold, the air-ground communication link disassembly module is called to work. When the air-ground data transmission handshake module encapsulates the air-ground data transmission handshake command according to the air-ground data transmission protocol, the airline operation system returns the air-ground data transmission handshake response command after receiving the air-ground data transmission handshake command. After the handshake is successful, the data transmission process begins.

[0051] Among them, when the security check is passed, the air-ground data transmission handshake module parses the air-ground data transmission task response command. When the air-ground data transmission task response command contains the status of the file to be transmitted, the air-ground data transmission handshake module decides whether to retransmit, retransmit or delete the same file on the machine according to the transmission file information contained in the response message.

[0052] 1.4. The air-to-ground data transmission module starts to send data to the airline operating system. Since the data transmission link adopts a reliable and secure transmission mechanism, the airline operating system does not need to send a data response confirmation package during the data transmission process. The air-to-ground data transmission module jumps to 1.3 after completing the transmission of a file to be transmitted; when all files to be transmitted on the aircraft are completed, it jumps to 1.5. When the data transmission link is detected to be interrupted during the transmission process, a link detection command is sent to the airline operating system. When the link detection passes, 1.2 is executed. If the link detection exceeds the threshold and fails, 1.6 is executed.

[0053] 1.5. When all files to be transmitted on board are transferred, the air-to-ground data transmission termination module sends a data termination command to the airline operation system. When the airline operation system receives the data termination command, it indicates that all onboard data has been transferred.

[0054] 1.6. When the safety threshold is exceeded or all files on board are transferred, in order to reduce the time window for malicious attacks on the aircraft by the ground, the air-ground data link disassembly module closes the data transmission link, the data encryption link, and the physical link.

[0055] The embodiment of the present invention provides an airborne end air-to-ground automated data rapid and secure transmission system and method. The system and method can rapidly and securely transmit onboard aircraft data to an airline operation and maintenance system when the aircraft is transferred, and the transmission rate can reach 80% of the actual available bandwidth, achieving good application effects.

[0056] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
