Description

Technical Field

[0001] This invention relates to the field of radar surveillance technology, and in particular to an aircraft surveillance system, method, device, and storage medium. Background Technology

[0002] Currently, my country's main aircraft surveillance methods include: primary surveillance radar, secondary surveillance radar, surface surveillance radar, ground-based ADS-B OUT, and ADS-C. Primary surveillance radar can only detect objects but cannot identify them (is the object an aircraft? What is its identification code?), and it cannot determine the aircraft's altitude. Secondary surveillance radar can obtain the distance, speed, aircraft identification code, and altitude between the aircraft and the radar; however, it cannot be used to monitor aircraft in areas where radar cannot be deployed, such as oceans or remote land areas. Surface surveillance radar is difficult to fully cover all parking positions in the terminal due to obstruction and interference from airport buildings, moving aircraft, and engineering vehicles. Ground-based ADS-B OUT requires ground stations and cannot be used to monitor aircraft in areas where ground stations cannot be deployed. ADS-C provides aircraft surveillance services based on the ACARS network. However, ACARS network data transmission costs are high, and aircraft surveillance requires frequent information exchange between the aircraft and the ground monitoring center, which significantly increases the operating costs of the aircraft. Furthermore, the altitude information provided by secondary surveillance radar, and the position and speed information provided by ADS-B OUT and ADS-C, do not originate from these systems themselves; they require data from other airborne systems to provide surveillance services.

[0003] In summary, how to achieve accurate dynamic monitoring, accurately identify the identification code information of the monitored aircraft, and enable real-time monitoring of aircraft in all BeiDou coverage areas are technical problems that need to be solved in this field. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide an aircraft monitoring system, method, device, and storage medium capable of accurate dynamic monitoring, accurate identification of the identification code information of the monitored aircraft, and real-time monitoring of aircraft in all BeiDou coverage areas.

[0017] Optionally, the airborne BeiDou module includes:

[0018] The command acquisition unit is used to acquire the positioning command based on RDSS service sent by the aircraft monitoring user terminal from the Beidou short message ground-to-air forwarding database through the aircraft monitoring service center and according to the aircraft identification information.

[0019] The location message sending unit is used to obtain the current location of the aircraft based on the positioning command and generate a corresponding current location short message, and send the current location short message to the aircraft monitoring service center.

[0020] Optionally, the airborne BeiDou module includes:

[0021] The information acquisition unit is used to acquire the aircraft identification information set by the user terminal through the preset human-machine interface in the airborne Beidou module and the communication address of the aircraft monitoring service center.

[0022] The message sending trigger unit is used to trigger the monitoring message sending function when it receives the message sending trigger condition set through the preset human-machine interface and / or the message sending trigger event set through Beidou short message.

[0023] Optionally, the aircraft surveillance system further includes:

[0024] Airborne equipment used to send identification information from aviation identification information to the airborne Beidou module.

[0025] Secondly, this application discloses an aircraft surveillance method, including:

[0026] The airborne Beidou module sends registration information, including aircraft identification information and the Beidou short message communication address of the airborne Beidou module, to the aircraft surveillance service center.

[0027] The aircraft surveillance service center communicates with the airborne BeiDou module via BeiDou short message communication based on the BeiDou short message communication address, obtains the surveillance messages sent by the airborne BeiDou module, and authenticates and authorizes the aircraft surveillance user terminal that sends and receives surveillance messages.

[0028] Once the aircraft monitoring user terminal passes authentication and authorization, it gains the authority to send monitoring messages through the aviation monitoring service center and to send control commands to the airborne BeiDou module of the target aircraft.

The aircraft surveillance user terminal is used to obtain the authority to send surveillance messages through the aircraft surveillance service center and to send control commands to the airborne BeiDou module of the target aircraft. As can be seen, the constructed aircraft surveillance system enables dynamic real-time monitoring and message feedback of aircraft. The airborne BeiDou module generates corresponding registration information to obtain monitoring permissions from the aircraft surveillance service center. Upon confirmation of the request from the air surveillance service center, a monitoring message about the monitored aircraft is immediately sent to the center in real time. Then, the air surveillance service center and the aircraft surveillance user terminal re-authenticate and verify the request to ensure the user terminal is authorized. The system also extracts the request from the user terminal regarding the target aircraft and sends the corresponding monitoring message to the user terminal. By using the BeiDou short message service to send the aircraft surveillance message, all-weather, high-precision dynamic monitoring of aircraft is achieved. The BeiDou time synchronization function ensures that the airborne BeiDou unit and the aircraft surveillance user terminal use a unified time reference, i.e., BeiDou time, enabling more accurate monitoring.

[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0040] Currently, my country's main aircraft surveillance methods include: primary surveillance radar, secondary surveillance radar, surface surveillance radar, ground-based ADS-B OUT, and ADS-C. Primary surveillance radar can only detect objects but cannot identify them (is the object an aircraft? What is its identification code?), and it cannot determine the aircraft's altitude. Secondary surveillance radar can obtain the distance, speed, aircraft identification code, and altitude between the aircraft and the radar; however, it cannot be used to monitor aircraft in areas where radar cannot be deployed, such as oceans or remote land areas. Surface surveillance radar is difficult to fully cover all parking positions in the terminal due to obstruction and interference from airport buildings, moving aircraft, and engineering vehicles. Ground-based ADS-B OUT requires ground stations and cannot be used to monitor aircraft in areas where ground stations cannot be deployed. ADS-C provides aircraft surveillance services based on the ACARS network. However, ACARS network data transmission costs are high, and aircraft surveillance requires frequent information exchange between the aircraft and the ground monitoring center, which significantly increases the operating costs of the aircraft. Furthermore, the altitude information provided by secondary surveillance radar, and the position and speed information provided by ADS-B OUT and ADS-C, do not originate from these systems themselves; they require data from other airborne systems to provide surveillance services.

[0041] To this end, the present invention provides an aircraft monitoring scheme that can achieve accurate dynamic monitoring, accurately identify the identification code information of the monitored aircraft, and perform real-time monitoring of aircraft in all BeiDou coverage areas.

[0042] Reference Figure 1 As shown in the figure, an embodiment of the present invention discloses an aircraft surveillance system, which includes: an airborne Beidou module 11, an aircraft surveillance service center 12, and an aircraft surveillance user terminal 13, wherein,

[0043] The airborne Beidou module 11 is used to send registration information containing aircraft identification information and the Beidou short message communication address of the airborne Beidou module 11 to the aircraft surveillance service center 12.

[0044] The aircraft surveillance service center 12 is used to receive the registration information, and to communicate with the airborne Beidou module 11 via Beidou short message according to the Beidou short message communication address, to obtain the surveillance message sent by the airborne Beidou module 11, and to authenticate and authorize the aircraft surveillance user terminal 13 that sends and receives the surveillance message request.

[0045] The aircraft monitoring user terminal 13 is used to obtain the monitoring messages sent through the aviation monitoring service center 12 and to send control commands to the airborne Beidou module of the target aircraft.

[0046] The aircraft surveillance system also includes:

[0047] Airborne equipment 14 is used to send identification information from aviation identification information to the airborne Beidou module.

[0048] It is understood that the airborne BeiDou module 11 includes: a startup unit 111, used to send registration information containing aircraft identification information and the BeiDou short message communication address of the airborne BeiDou module 11 to the aircraft surveillance service center 12 when sending startup information to the BeiDou short message center station; specifically, the startup unit 111 sends the corresponding startup information to the BeiDou short message center station to start the airborne BeiDou module 11, so that the powered-on airborne BeiDou module 11 can send registration information containing aircraft identification information and its own BeiDou short message communication address to the aircraft surveillance service center 12, for providing the aircraft surveillance service center 12 with its own BeiDou short message communication address and the aircraft information monitored by the BeiDou short message communication card in the airborne BeiDou module 11. It should be noted that at least one BeiDou short message communication card is installed in the airborne BeiDou module 11. Generally, multiple BeiDou short message communication cards are installed for two-way air-to-ground communication with the aircraft surveillance service center 12. The content of the aircraft identification information can be set by the user through the HMI or obtained from other airborne equipment 14.

[0049] It is understood that the shutdown unit 112 is used to send cancellation registration information to the aircraft surveillance service center 12 when sending shutdown information to the Beidou short message center station; specifically, the shutdown unit 112 can send the corresponding shutdown information to the Beidou short message center station when the airborne Beidou module 11 is shut down, and at the same time send the corresponding cancellation registration information to the aircraft surveillance service center 12.

[0050] It is understood that the update unit 113 is used to resend the updated registration information to the aircraft surveillance service center when the registration information is detected to be updated. Specifically, when the update unit 113 detects that the airborne Beidou module 11 is in a state of not being turned off, that is, in a normal operating state, if the aircraft identification information or Beidou card number has changed, the airborne Beidou unit will resend the registration information to the Beidou aircraft surveillance service center; specifically, if the airborne Beidou module 12 detects a change in the aircraft identification information or Beidou card number during normal operation, it updates the original registration information and resends the updated registration information containing the new aircraft identification information or the new Beidou card number to the aircraft surveillance service center 12.

[0051] It is understood that the airborne BeiDou module 11 includes: an instruction acquisition unit 114, used to obtain a positioning command based on RDSS service sent by the aircraft monitoring user terminal from the BeiDou short message ground-to-air forwarding database through the aircraft monitoring service center and according to the aircraft identification information; specifically, the instruction acquisition module 14 in the airborne BeiDou module 11 obtains the positioning command based on RDSS service sent by the aircraft monitoring user terminal to the target aircraft in the aircraft identification information from the BeiDou short message ground-to-air forwarding database maintained by the aircraft monitoring service center. It should be noted that the positioning command based on RDSS service is the current location information of the airborne BeiDou module 11 after the instruction acquisition unit 114 obtains the sent positioning command and obtains its own RDSS service.

[0052] It is understood that the position message sending unit 115 is used to obtain the current position of the aircraft based on the positioning command and generate a corresponding current position short message, and send the current position short message to the aircraft surveillance service center. Specifically, after the airborne Beidou module 11 obtains the Beidou short message rapid positioning command sent by the aircraft surveillance service center 12 from the Beidou short message ground-to-air forwarding database, the Beidou module 11 records that it uses the Beidou RDSS service to quickly obtain the current position of the target aircraft and feeds it back to the aircraft surveillance service center 12 via Beidou short message. Generally speaking, the airborne Beidou module 11 has Beidou RNSS and RDSS functions. When the Beidou RNSS service is available, the current position of the target aircraft obtained through the RNSS service is fed back to the aircraft surveillance service center 12; while the Beidou RDSS service obtains its own current position and sends the corresponding position message on demand, that is, it can only be sent after receiving the corresponding positioning command based on the RDSS service. As can be seen, based on the BeiDou RDSS function, the aircraft monitoring user terminal 13 sends a position query command to the airborne BeiDou module 11 through the ground monitoring center to quickly locate the aircraft's position. Correspondingly, since the airborne BeiDou module 11 has both navigation, positioning, and communication functions, it does not need to rely on other avionics systems to provide aircraft status information. In addition, using the BeiDou time synchronization function, the airborne BeiDou module 11 and the ground monitoring system use a unified time reference, namely BeiDou time, to achieve more accurate monitoring.

[0053] It is understood that the aircraft surveillance service center 12 is used to maintain the BeiDou short message ground-to-air forwarding database, and can send commands and requests sent by the aircraft surveillance user terminal to the airborne BeiDou unit through BeiDou short messages according to the aircraft identification information; and maintain the BeiDou short message air-to-ground forwarding database, and can forward aircraft surveillance messages to specific aircraft surveillance user terminals according to the aircraft identification information. In addition, the Aircraft Surveillance Service Center 12 is used to receive registration information sent from the airborne Beidou module 11, and to obtain aircraft identification information and Beidou short message communication address from the registration information. It is used to send or receive relevant Beidou short messages to or from the Beidou short message communication address via Beidou short message. At the same time, the Aircraft Surveillance Service Center 12 can also communicate with multiple aircraft surveillance user terminals through the ground network. As a Beidou short message air-to-ground communication gateway and a Beidou surveillance message distribution center, it can forward the surveillance messages sent by the Beidou module 11 to the aircraft surveillance user terminals 13 that have passed the authentication and authorization of the Aircraft Surveillance Service Center 12. Since the Aircraft Surveillance Service Center 12 is equipped with multiple Beidou short message communication cards, it has the ability to conduct two-way air-to-ground communication with multiple airborne Beidou modules 11. As a result, the aircraft surveillance service center 12 may collect surveillance messages from multiple aircraft at the same time. Therefore, it is necessary to authenticate and authorize the aircraft surveillance user terminal 13 that has applied to receive surveillance messages to determine whether the aircraft surveillance user terminal 13 is an authorized aircraft surveillance user terminal, so as to avoid obtaining surveillance messages from aircraft that should not be obtained.

[0054] It is understood that the aircraft monitoring user terminal 13 communicates with the aircraft monitoring service center 12 via a ground network, logs into the BeiDou aircraft monitoring service center, and obtains permission to receive BeiDou monitoring messages for the target aircraft. The number of target aircraft can be one or more. After obtaining the corresponding BeiDou monitoring message receiving permission, it can receive monitoring messages about the target aircraft forwarded by the aircraft monitoring service center 12, process and display the received monitoring messages, and the specific operations may include, but are not limited to: real-time location display of the target aircraft, location prediction of the target aircraft, and trajectory recording of the target aircraft.

[0055] Therefore, this application discloses an aircraft surveillance system, which includes: an airborne BeiDou module, an aircraft surveillance service center, and an aircraft surveillance user terminal. The airborne BeiDou module is used to send registration information containing aircraft identification information and the BeiDou short message communication address of the airborne BeiDou module to the aircraft surveillance service center. The aircraft surveillance service center is used to receive the registration information, conduct BeiDou short message communication with the airborne BeiDou module according to the BeiDou short message communication address, obtain surveillance messages sent by the airborne BeiDou module, and authenticate and authorize the aircraft surveillance user terminal that sends and receives surveillance message requests. The aircraft surveillance user terminal is used to obtain the authority to send surveillance messages through the aircraft surveillance service center and to send control commands to the airborne BeiDou module of the target aircraft. As can be seen, the constructed aircraft surveillance system enables dynamic real-time monitoring and message feedback of aircraft. The airborne BeiDou module generates corresponding registration information to obtain monitoring permissions from the aircraft surveillance service center. Upon confirmation of the request from the air surveillance service center, a monitoring message about the monitored aircraft is immediately sent to the center in real time. Then, the air surveillance service center and the aircraft surveillance user terminal re-authenticate and verify the request to ensure the user terminal is authorized. The system also extracts the request from the user terminal regarding the target aircraft and sends the corresponding monitoring message to the user terminal. By using the BeiDou short message service to send the aircraft surveillance message, all-weather, high-precision dynamic monitoring of aircraft is achieved. The BeiDou time synchronization function ensures that the airborne BeiDou unit and the aircraft surveillance user terminal use a unified time reference, i.e., BeiDou time, enabling more accurate monitoring.

[0056] Reference Figure 2 As shown, this embodiment of the invention discloses a specific aircraft monitoring system. Compared with the previous embodiment, this embodiment further explains and optimizes the technical solution. Specifically:

[0057] It is understood that the aircraft surveillance service center 12 also includes: a dynamic selection unit, used to dynamically select one of the multiple Beidou short message cards installed in the Beidou aircraft surveillance service that meets the message sending interval limit when the Beidou short message service has a limit on the sending interval of the surveillance message, and send a short message to the airborne Beidou module 11. The sending interval of the surveillance message of the civilian communication card is generally 60 seconds.

[0058] The interval command forwarding unit is used to receive a command sent by the aircraft monitoring user terminal 13 specifying the transmission interval of a certain aircraft monitoring message, and then forward the monitoring message transmission interval command to the airborne Beidou module 11 via Beidou short message.

[0059] The request forwarding unit is used to receive the aircraft monitoring message request triggered by the subscription event sent by the aircraft monitoring user terminal 13, and then forward the aircraft monitoring message request triggered by the subscription event to the airborne Beidou module 11 via Beidou short message.

[0060] It is understood that the aircraft monitoring user terminal 13 includes a periodic setting unit 131, used to send periodic BeiDou short messages representing the set sending period to the airborne BeiDou module through the aircraft monitoring service center. It should be noted that firstly, control permissions for the airborne BeiDou module 11 of the target aircraft must be obtained. Specifically, this requires logging into the aircraft monitoring service center 12 and obtaining authentication and authorization from the air monitoring service center to gain control permissions for the airborne BeiDou module 11. Specifically, after obtaining the corresponding permissions, the time interval for the airborne BeiDou module 11 to send monitoring messages can be set; after obtaining the corresponding permissions, a subscription event to trigger the airborne BeiDou module 11 to send monitoring messages can be set; after obtaining the corresponding permissions, the airborne BeiDou module 11 can be commanded to perform rapid positioning and report the positioning results via BeiDou short messages; after obtaining the corresponding permissions, the emergency working mode of the airborne BeiDou module 11 can be set / cleared.

[0061] It is understood that the airborne BeiDou module 11 includes a message sending unit 116, used to parse the periodic BeiDou short messages to obtain the sending period, and send a monitoring message containing aircraft identification information and aircraft status information to the aircraft surveillance service center 12 based on the sending period. Specifically, since the initial period for sending monitoring messages by the airborne BeiDou module 11 is a default value, the aircraft surveillance user terminal 13 can change the period by sending BeiDou short messages through the aircraft surveillance service center. However, it should be noted that the changed period is not lower than the minimum sending interval supported by the BeiDou short message card. The changed period is used to periodically send monitoring messages to the BeiDou aircraft surveillance service center. The monitoring messages contain aircraft identification information and aircraft status information, such as longitude, latitude, altitude, speed, and timestamp.

[0062] It is understood that the airborne BeiDou module 11 includes: an information acquisition unit 117, used to acquire aircraft identification information and the communication address of the aircraft monitoring service center set by the user terminal through the preset human-machine interface in the airborne BeiDou module 11; and a message sending trigger unit 118, used to trigger the monitoring message sending function when a message sending trigger condition set through the preset human-machine interface is received, and / or a message sending trigger event set through BeiDou short messages is received. It is understood that the information acquisition unit 117 enables the user terminal to set the corresponding aircraft identification information and the communication address of the aircraft monitoring service center through the HMI interface set in the airborne BeiDou module 11. The airborne BeiDou module 11 supports event-triggered monitoring message sending functions, such as excessively rapid climb / descent rate, deviation from the flight path, exceeding / below a specified altitude, etc. Users can set climb / descent rate, flight path information, altitude limits, etc. through the HMI interface, or they can send BeiDou short messages to set these parameters. Specifically, it can be configured to send monitoring messages when the climb / descent rate is exceeded, when the flight path is deviated from, and when the altitude is above or below a specified altitude.

[0063] Onboard users can set the airborne BeiDou module 11 to emergency operating mode via the HMI interface. In emergency operating mode, the airborne BeiDou module 11 transmits aircraft status information using the minimum transmission interval supported by the BeiDou short message card. Users can also clear the emergency operating mode of the airborne BeiDou unit using the HMI interface. The BeiDou short message communication address of the Aircraft Surveillance Service Center 12 can be set by the user via the HMI interface, or by the Aircraft Surveillance Service Center 12 sending a short message to the airborne BeiDou module 11.

[0064] Therefore, it can be seen that the airborne Beidou module 11 supports ground-based modification of the periodic monitoring message transmission cycle via Beidou short messages, enabling adjustment of the airborne Beidou module 11's monitoring message transmission cycle to better meet the needs of the user end. In addition, the airborne Beidou module 11 supports ground-based modification of event-triggered messages via Beidou short messages and supports setting the airborne Beidou module 11 to emergency mode. The aforementioned triggering events and emergency mode settings of the airborne Beidou module 11 further allow users on both the user end and the airborne end to adjust the monitoring of the aircraft according to actual needs, thus ensuring a better user experience.

[0065] Reference Figure 3 As shown, this embodiment of the invention also discloses an aircraft monitoring method, including:

[0066] Step S11: The airborne Beidou module sends registration information, including aircraft identification information and the Beidou short message communication address of the airborne Beidou module, to the aircraft surveillance service center.

[0067] In this embodiment, the airborne BeiDou module sends a corresponding registration request to the Aircraft Surveillance Service Center. Through this registration request, the airborne BeiDou module can provide the Aircraft Surveillance Service Center with the identification information of all current aircraft, as well as the BeiDou short message communication address of the airborne BeiDou module.

[0068] Step S12: The aircraft surveillance service center communicates with the airborne Beidou module via Beidou short message communication based on the Beidou short message communication address, obtains the surveillance message sent by the airborne Beidou module, and authenticates and authorizes the aircraft surveillance user terminal that sends and receives the surveillance message request.

[0069] In this embodiment, BeiDou short message communication is performed between the BeiDou module and the BeiDou short message communication address to obtain monitoring messages sent by the airborne BeiDou module. Simultaneously, the obtained monitoring messages are forwarded to authorized aircraft monitoring user terminals. The aircraft monitoring service center can also perform corresponding authentication and authorization for the aircraft monitoring user terminals. Correspondingly, the air monitoring service center can receive corresponding request instructions sent by authenticated and authorized aircraft monitoring user terminals, and can choose whether to forward monitoring messages to the aircraft monitoring user terminals based on these instructions, or send control instructions sent by the aircraft monitoring user terminals to the airborne BeiDou module of the corresponding target aircraft via BeiDou short message.

[0070] Step S13: After the aircraft monitoring user terminal passes authentication and authorization, it obtains the authority to send monitoring messages through the aviation monitoring service center and to send control commands to the airborne Beidou module of the target aircraft.

[0071] In this embodiment, after the aircraft monitoring user terminal passes the authentication and authorization of the aircraft monitoring service center, it obtains the monitoring messages forwarded by the aircraft monitoring service center and sends corresponding control requests to the airborne Beidou module through the aircraft monitoring service center.

[0072] Therefore, this application discloses the following: sending registration information containing aircraft identification information and the BeiDou short message communication address of the airborne BeiDou module to the aircraft surveillance service center; receiving the registration information and communicating with the airborne BeiDou module via BeiDou short message according to the BeiDou short message communication address to obtain surveillance messages sent by the airborne BeiDou module; authenticating and authorizing the aircraft surveillance user terminal that sends and receives surveillance messages; and obtaining the authority to send surveillance messages through the aircraft surveillance service center and to send control commands to the airborne BeiDou module of the target aircraft. As can be seen, the constructed aircraft surveillance system enables dynamic real-time monitoring and message feedback of aircraft. The airborne BeiDou module generates corresponding registration information to obtain monitoring permissions from the aircraft surveillance service center. Upon confirmation of the request from the air surveillance service center, a monitoring message about the monitored aircraft is immediately sent to the center in real time. Then, the air surveillance service center and the aircraft surveillance user terminal re-authenticate and verify the request to ensure the user terminal is authorized. The system also extracts the request from the user terminal regarding the target aircraft and sends the corresponding monitoring message to the user terminal. By using the BeiDou short message service to send the aircraft surveillance message, all-weather, high-precision dynamic monitoring of aircraft is achieved. The BeiDou time synchronization function ensures that the airborne BeiDou unit and the aircraft surveillance user terminal use a unified time reference, i.e., BeiDou time, enabling more accurate monitoring.
