Description

Technical Field

[0001] This invention relates to the field of aircraft technology, and in particular to a backup tuning system, method, computer-readable storage medium, and computer device. Background Technology

[0002] In the aviation field, a radio navigation system refers to a system that uses radio navigation stations and airborne radio navigation equipment to guide an aircraft safely to its destination along a prescribed route. It mainly includes Automatic Direction Finder (ADF), Distance Measuring Equipment (DME), Very High Frequency Omnidirectional Range (VOR), Instrument Landing System (ILS) / Given Ground Landing System (GLS) / Stellar-Based Landing System (SLS), and others. All of these radio navigation devices need to be tuned to the same frequency as the ground navigation stations to function properly. For operational safety reasons, airworthiness regulations require civil aircraft to be equipped with two independent radio navigation systems for redundancy and backup.

[0003] Currently, the main tuning function of radio navigation systems is generally achieved through the Flight Controller System (FMS). The main tuning of the FMS can be divided into VOR and ADF tuning, and simultaneously tuning of the left or right ILS / GLS / SLS. Figure 1 This is an example of the FMS master tuning method or system for a conventional aircraft radio navigation system.

[0004] Typically, FMS master tuning failures take two forms. Failure type 1 is a failure before entering the central network, such as... Figure 3 As shown, this is called FMS manifestation type 1 fault, including faults such as FMS main function failure and FMS-central network link failure; Fault type 2 is: faults after entering the central network and before completing tuning, such as... Figure 3 As shown, this is known as FMS manifestation type 2 failure, including issues such as tuning data routing errors and link failures between the central network and radio navigation equipment. Both types of failures will cause the FMS primary tuning function to fail, thus preventing the flight crew from receiving effective flight guidance. Currently, backup tuning is typically used to address the aforementioned problems with the FMS primary tuning function failure.

[0005] However, existing systems for backup tuning of radio navigation have various defects and shortcomings. For example, Figure 2 This is an example of a system for backup tuning of the radio navigation system of a conventional aircraft. In this backup tuning design, the backup tuning function is performed only on the left-side radio navigation equipment via the left-side tuning control panel (TCP), while the right-side radio navigation equipment, including ADF, DME, VOR, and ILS / GLS / SLS, is not designed with backup tuning functionality.

[0006] More seriously, when the FMS primary tuning function is functioning correctly, if the crew operates the left-side tuning control panel to perform backup tuning of the left-side radio navigation equipment, the operating frequency of the left-side radio navigation equipment will change accordingly, while the operating frequency of the right-side radio navigation equipment will remain at the FMS primary tuning frequency. Therefore, this backup tuning method or system will cause the operating frequencies of the left and right ILS to be inconsistent. This inconsistency will ultimately result in different approach and landing warnings on the left and right primary displays (PFDs) observed by the pilot and first officer, which will greatly mislead the flight crew. Moreover, especially during the critical flight phase of approach and landing, this misleading situation poses a catastrophic risk, potentially leading to a crash and loss of life. Furthermore, the current FMS primary tuning function cannot guarantee the highest priority of human intervention.

[0007] In view of this, it is necessary to develop a new backup tuning system, method, computer-readable storage medium, and computer device to solve the above problems. Summary of the Invention

[0008] Embodiments of this application provide a backup tuning system, method, computer-readable storage medium, and computer device to solve the technical problems in the prior art where backup tuning methods result in inconsistent operating frequencies on different sides and cannot guarantee the highest priority of human control.

[0011] The main tuning unit includes a first main tuning subunit and a second main tuning subunit;

[0012] A backup tuning unit includes a first tuning control board and a second tuning control board. Both the first and second tuning control boards have a manual backup tuning mode. The manual backup tuning mode of the first and second tuning control boards has a higher priority than the main tuning of the first and second main tuning subunits. The first tuning control board is used to read the main tuning status data of the first main tuning subunit to determine whether the first main tuning subunit is faulty. The second tuning control board is used to read the main tuning status data of the second main tuning subunit to determine whether the second main tuning subunit is faulty.

[0013] An execution unit, comprising a radio navigation device; a first tuning control board or a second tuning control board for performing backup tuning of the radio navigation device; either the first tuning control board or the second tuning control board for performing backup tuning of the radio navigation device; and the first tuning control board for performing synchronous backup tuning with the second tuning control board.

[0014] In addition to one or more of the features disclosed above, or alternatively, a transmission unit is also included, which is connected between the first tuning control board and the second tuning control board to enable the first tuning control board and the second tuning control board to perform synchronous backup tuning.

[0015] In addition to one or more of the features disclosed above, or alternatively, the backup tuning unit includes a backup tuning port that is active.

[0016] In addition to one or more of the features disclosed above, or alternatively, the backup tuning unit includes a multi-function keyboard area for inputting and displaying the target backup tuning frequency.

[0017] In addition to one or more of the features disclosed above, or as an alternative, the transmission unit includes a first transmission medium and a second transmission medium, the first transmission medium being connected between the first tuning control board and the second tuning control board for data output; the first transmission medium is a cable or a network.

[0018] The second transmission medium is used by the first tuning control board to monitor the main tuning state of the first main tuning subunit, and the second transmission medium is used by the second tuning control board to monitor the main tuning state of the second main tuning subunit.

[0019] On the other hand, a backup tuning method is further disclosed, which includes the following steps:

[0020] (1) The first tuning control board monitors the main tuning state of the first main tuning subunit, and the second tuning control board monitors the main tuning state of the second main tuning subunit.

[0021] (2) Determine whether the main tuning state of the first main tuning subunit and the main tuning state of the second main tuning subunit are both in fault condition; if yes, proceed to the next step (3); if no, determine whether the first tuning control board or the second tuning control board has entered the manual backup tuning mode; if yes, the first tuning control board or the second tuning control board performs manual backup tuning and proceeds to the next step (3); if no, the first main tuning subunit and the second main tuning subunit perform main tuning.

[0022] (3) Either the first tuning control board or the second tuning control board performs backup tuning for the radio navigation device, and the first tuning control board and the second tuning control board perform synchronous backup tuning.

[0023] In addition to one or more of the features and / or steps disclosed above, or as an alternative, the backup tuning ports of both the first tuning control board and the second tuning control board are enabled.

[0024] In addition to one or more of the features and / or steps disclosed above, or as an alternative, before performing backup tuning on the radio navigation device, the target backup tuning frequency of the first tuning control board is manually input and the target backup tuning frequency is synchronized to the second tuning control board; or, the target backup tuning frequency of the second tuning control board is manually input and the target backup tuning frequency is synchronized to the first tuning control board.

[0025] On the other hand, a computer device is further disclosed, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method.

[0026] On the other hand, a computer-readable storage medium is further disclosed, on which a computer program is stored, which, when executed by a processor, implements the steps of the method.

[0027] One of the above technical solutions has the following advantages or beneficial effects: When the main tuning function of the main tuning unit fails, the backup tuning function can accurately and efficiently control the radio navigation system, enabling the aircraft to receive timely navigation guidance. This avoids the traditional tuning method where the operating frequency of radio equipment on one side is inconsistent with that on the other side due to backup tuning. It provides unified approach and landing prompts for the same radio navigation equipment operating frequency on the left and right main displays observed by the pilot and co-pilot. Especially during the critical flight phase of approach and landing, this significantly improves the aircraft's safety margin and reduces the probability of accidents. Furthermore, the manual backup tuning mode of the first and second tuning control boards has a higher priority than the main tuning of the first and second main tuning subunits, ensuring the highest priority level for manual operation.

[0039] Reference Figure 3 , Figure 3This is a schematic diagram of a system for backup tuning in radio navigation, which can implement embodiments of the present invention. The system for backup tuning in radio navigation provided in this application includes a main tuning unit 100, a backup tuning unit 200, an execution unit 300, and a transmission unit 400.

[0040] The main tuning unit 100 specifically includes a first main tuning subunit 110 and a second main tuning subunit 120, which are used for main tuning. The backup tuning unit 200 includes a first tuning control board 210 and a second tuning control board 220. Both the first tuning control board 210 and the second tuning control board 220 have a manual backup tuning mode. The manual backup tuning mode of the first tuning control board 210 and the second tuning control board 220 has a higher priority than the main tuning of the first main tuning subunit 110 and the second main tuning subunit 120. Furthermore, the first tuning control board 210 is used to input the backup tuning frequency and to periodically read the main tuning status data of the first main tuning subunit 110. The first tuning control board 210 is used to determine whether the first main tuning subunit 110 is in a fault state. The second tuning control board 220 is used to input the backup tuning frequency and to periodically read the main tuning status data of the second main tuning subunit 120. The second tuning control board 220 is used to determine whether the second main tuning subunit 120 is in a fault state.

[0041] The execution unit 300 includes a radio navigation device 310; either the first tuning control board 210 or the second tuning control board 220 is used to perform backup tuning of the radio navigation device 310; and the first tuning control board 210 is used to perform synchronous backup tuning with the second tuning control board 220.

[0042] Specifically, the execution unit 300 includes a radio navigation device 310 located at a first position and a radio navigation device 310 located at a second position. When the first tuning control board 210 detects that the first main tuning subunit 110 is in a fault state, or when the second tuning control board 220 detects that the second main tuning subunit 120 is in a fault state, the first tuning control board 210 performs backup tuning on the radio navigation device 310 located at the first position, and synchronizes the backup tuning data to the second tuning control board 220; or the second tuning control board 220 performs backup tuning on the radio navigation device 310 located at the second position, and synchronizes the backup tuning data to the first tuning control board 210. The radio navigation device 310 includes ADF, DME, VOR, and ILS / GLS / SLS related equipment, and is the target terminal for backup tuning.

[0043] Specifically, the backup tuning unit 200 includes a backup tuning port, that is, both the first tuning control board 210 and the second tuning control board 220 include a backup tuning port, which is in an active state.

[0044] Furthermore, the backup tuning unit 200 includes a multi-function keyboard area for inputting and displaying the target backup tuning frequency of the first tuning control board 210, or for inputting and displaying the target backup tuning frequency of the second tuning control board 220. Additionally, the backup tuning unit 200 can support input and display at the thousandths level of frequency.

[0045] It should be noted that the transmission unit 400 of the backup tuning system in the radio navigation equipment of this application is connected between the first tuning control board 210 and the second tuning control board 220 to realize synchronous backup tuning of the first tuning control board 210 and the second tuning control board 220. Specifically, the transmission unit 400 includes a central network 410, a first transmission medium and a second transmission medium. The central network 410 is connected between the main tuning unit 100 and the execution unit 300. The first transmission medium is connected between the first tuning control board 210 and the second tuning control board 220 to realize data transmission between the first tuning control board 210 and the second tuning control board 220. The first transmission medium is a cable or a network. The second transmission medium is used by the first tuning control board 210 to monitor the main tuning state of the first main tuning subunit 110, and by the second tuning control board 220 to monitor the main tuning state of the second main tuning subunit 120.

[0046] The backup tuning system for radio navigation equipment proposed in this application uses a first tuning control board 210 to periodically read the main tuning status data of the first main tuning subunit 110 and a second tuning control board 220 to periodically read the main tuning status data of the second main tuning subunit 120, and determines whether the two FMS, namely the first main tuning subunit 110 and the second main tuning subunit 120, are in a fault state. If both FMS main tuning is in a fault state, the backup tuning function is executed. The first tuning control board 210 and the second tuning control board 220 are interconnected through a transmission medium, thereby synchronizing the tuning data. That is, when either the first tuning control board 210 or the second tuning control board 220 performs backup tuning on a radio navigation device 310 at a corresponding location, the tuning data will be automatically synchronized to the interconnected first tuning control board 210 or the second tuning control board 220 to complete the backup tuning operation of the other radio navigation device 310, that is, to maintain the consistency of the backup tuning frequencies of the radio navigation devices 310 on both sides.

[0047] See Figure 4 , Figure 4The present application provides a schematic flowchart for backup tuning in radio navigation, which is an embodiment of the present application. The present application also provides a backup tuning method for radio navigation, the backup tuning method comprising the following steps:

[0048] (1) The first tuning control board 210 monitors the main tuning state of the first main tuning subunit 110, and the second tuning control board 220 monitors the main tuning state of the second main tuning subunit 120.

[0049] That is, the first tuning control board 210 and the second tuning control board 220 periodically monitor the main tuning fault status of the main tuning unit 100;

[0050] (2) Determine whether the first main tuning subunit 110 and the second main tuning subunit 120 are faulty; if yes, proceed to the next step (3); if no, determine whether the first tuning control board 210 or the second tuning control board 220 has entered the manual backup tuning mode; if yes, the first tuning control board 210 or the second tuning control board 220 performs manual backup tuning and proceeds to the next step (3); if no, the first main tuning subunit 110 and the second main tuning subunit 120 perform main tuning.

[0051] (3) Either the first tuning control board 210 or the second tuning control board 220 performs backup tuning for the radio navigation device 310, and the first tuning control board 210 and the second tuning control board 220 perform synchronous backup tuning.

[0052] In this step (3), before performing backup tuning on the radio navigation device 310, the target backup tuning frequency of the first tuning control board 210 is manually input and synchronized to the second tuning control board 220; or, the target backup tuning frequency of the second tuning control board 220 is manually input and synchronized to the first tuning control board 210.

[0053] The first tuning control board 210 and the second tuning control board 220 are always in an active state, and the backup tuning ports of the first tuning control board 210 and the second tuning control board 220 are both set to an active state.

[0054] This application also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method described therein.

[0055] This application also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method.

[0056] In the backup tuning system, method, computer device, and computer-readable storage medium for radio navigation equipment proposed in this application, the tuning status data of the main tuning unit 100 is periodically monitored by the first tuning control board 210 and the second tuning control board 220. When the first main tuning subunit 110 and the second main tuning subunit 120 are found to be in a fault state, the tuning data manually input in the backup tuning mode of either the first tuning control board 210 or the second tuning control board 220 is first synchronized with the tuning data of the other interconnected first tuning control board 210 or second tuning control board 220. Then, the two tuning data are respectively transmitted through the backup tuning interface on the radio navigation equipment 310 at the corresponding position to realize the backup tuning of the radio navigation equipment 310 at the corresponding position. This backup tuning method, when a main tuning function failure is detected in the main tuning unit 100, can achieve backup tuning of both sets of radio navigation equipment 310 by synchronously backing up the tuning data of either the first tuning control board 210 or the second tuning control board 220 of the backup tuning unit 200. This backup tuning method effectively avoids prioritizing the FMS tuning frequency when the FMS main tuning function is normal, thus obtaining more accurate navigation guidance; it also avoids the traditional tuning method where backup tuning leads to inconsistent operating frequencies of the left and right radio navigation equipment. It provides unified approach and landing prompts with the same radio navigation equipment operating frequency on the left and right main displays (PFDs) observed by the pilot and co-pilot, which greatly improves aircraft safety margin and reduces the probability of accidents, especially during critical flight phases of approach and landing. Furthermore, the manual backup tuning mode of the first tuning control board 210 and the second tuning control board 220 has a higher priority than the main tuning of the first main tuning subunit 110 and the second main tuning subunit 120, ensuring the highest priority level for manual operation.

[0057] The backup tuning system, method, computer-readable storage medium, and computer device provided in the embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the above embodiments are only for the purpose of helping to understand the technical solutions and core ideas of this application. Those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
