Description

Technical Field

[0001] The present application relates to the technical field of avionics systems, and in particular to a method, device, equipment and storage medium for acquiring off-block time. Background Art

[0002] Block time is an important parameter for airlines to prepare flight plans. It is also an important indicator for evaluating the daily utilization rate of aircraft and the efficiency of air traffic control. It plays a very important role in instructing the dispatchers of the airport operation control center and the ground control personnel of the air traffic control center to grasp the use of parking spaces in real time. Among them, the off-block time is usually defined as the time it takes for an aircraft to be pushed out of the parking space. At present, in the actual flight support process, the block time is mainly obtained through the following methods:

[0003] In the early years, the off-block time was manually recorded by maintenance personnel in paper forms and then uploaded to other information systems (such as the A-CDM system). Later, it was improved to record in handheld electronic terminals and directly upload to other information systems. However, in actual application, due to the complexity of maintenance work and the lack of verification methods, delayed recording, erroneous recording or even non-recording often occurs, and the timeliness and accuracy are poor;

[0004] Aircraft equipped with the ACARS system will automatically send time information when the parking brake is retracted. However, in actual operation, the retraction of the parking brake does not mean that the aircraft has been pushed out of the parking stand, and cannot fully indicate the aircraft's use of the parking stand, so the accuracy is insufficient;

[0005] By installing a camera above the parking space, the parking space is image-recognized. When the aircraft is detected to have slid out of the parking space, the time is automatically recorded. However, the accuracy of image recognition will be significantly reduced at night and in poor visibility.

[0006] By installing sensors and communication modules on the wheel chocks, when the maintenance personnel move them, the wheel chock position is sent through the communication module and compared with the aircraft position to determine whether the aircraft is parked at the parking position. However, this type of method requires the construction of a corresponding ground network to receive the communication information of the wheel chocks, and also increases the complexity and cost of the wheel chocks, making it difficult to be widely used. Summary of the invention

[0043] S101, when it is detected that the parking brake of the aircraft is set to be released, determining whether the aircraft starts to be pushed out according to the ground speed information of the aircraft.

[0044] Because the parking brake needs to be set to OFF before the aircraft is pushed out of the parking position, the parking brake position is determined by real-time monitoring of the data of the onboard data bus. If it is in the OFF position, it is necessary to determine whether the aircraft has started to be pushed out based on the ground speed information of the aircraft; if it is in the ON position, it is continuously monitored whether the parking brake of the aircraft is set to be released.

[0045] Specifically, by monitoring the ground speed information of the aircraft in real time, it is determined whether the aircraft has started to push out. x >0m / s, it is confirmed that the machine is turned on and the push-out starts.

[0046] S102: If it is determined that the aircraft is pushed out, whether the aircraft is pushed out of the parking stand is determined based on the real-time position of the aircraft and the position information of the parking stand where the aircraft is located.

[0047] In this embodiment, before determining whether the aircraft is pushed out of the parking stand based on the real-time position of the aircraft and the position information of the parking stand where the aircraft is located, the method also includes: obtaining the real-time position of the aircraft; matching the real-time position of the aircraft with an airport database to determine the parking stand where the aircraft is located and the position of the parking stand, wherein the airport database stores the position information of each parking stand at the airport.

[0048] Specifically, this application obtains the position of the aircraft (longitude lon) in real time x , latitude lat x )、ground speed information(v x ), and timing information (t). Obtain aircraft identity information (registration number, flight number) as well as airport database data and flight plan (departure airport). Based on the location information, retrieve the parking position information of the departure airport from the airport database, determine the current aircraft parking position (Y), and the longitude of parking position Y (lon y ), latitude (lat y ).

[0049] In an optional embodiment provided in the present application, judging whether the aircraft is pushed out of the parking stand according to the real-time position of the aircraft and the position information of the parking stand where the aircraft is located includes:

[0050] S1021, calculating a relative position distance according to the real-time position of the aircraft and the position information of the parking space where the aircraft is located.

[0051] Specifically, this embodiment determines whether the aircraft is pushed out of the parking stand by calculating the distance Z between the position of the aircraft and the position of the parking stand in real time, such as calculating the relative position distance by the following formula:

[0052] Z=2r*arcsin(sqrt(sin^2((lat y -lat X ) / 2)+cos(latx)*cos(lat y )*sin^2((lon y -lon x ) / 2)));

[0053] Among them, Z is the relative position distance, lat X The latitude of the aircraft's real-time position, lat y is the latitude in the location information of the parking position, lon x is the longitude of the aircraft in real-time position, lon y The longitude in the location information of the parking position is r=6371 km.

[0054] S1022: If the relative position distance is greater than a preset value, determine that the aircraft is pushed out of the parking position.

[0055] S103: If the aircraft is pushed out of the parking stand, the timing information at this time is determined as the off-block time.

[0056] If the aircraft is pushed out of the parking stand, the timing information t at this time is recorded as the off-block time.

[0057] S104, sending the off-block time, registration number, and flight number of the aircraft to the ground information system via a Beidou short message.

[0058] The embodiment of the present invention provides a method for obtaining the off-block time. When it is detected that the parking brake of an aircraft is set to be released, it is determined whether the aircraft starts to push out according to the ground speed information of the aircraft; if it is determined that the aircraft pushes out, it is determined whether the aircraft pushes out of the parking stand according to the real-time position of the aircraft and the position information of the parking stand where the aircraft is located; if the aircraft pushes out of the parking stand, the timing information at this time is determined as the off-block time. Compared with the prior art that determines the off-block time by manual methods, the present application, on the one hand, obtains the aircraft position, ground speed information and timing information in real time by receiving and solving Beidou satellite navigation signals, and on the other hand, directly reads and monitors the aircraft data in real time through the airborne bus, and then determines the off-block time according to the relevant data of the aircraft (the ground speed information, real-time position and timing information of the aircraft). Therefore, the present application can improve the timeliness and accuracy of data collection, save manpower, reduce the difficulty of construction, and is not affected by night and other external weather conditions.

[0059] See also Figure 2 and Figure 3 , is a method for obtaining off-block time provided by an embodiment of the present invention, the method specifically comprising:

[0061] Step 2: The Beidou terminal obtains the aircraft identity information (registration number) by interconnecting with the airborne data bus.

[0062] Step 3: The Beidou terminal obtains airport database data by interconnecting with the airborne data bus.

[0063] Step 4: The Beidou terminal obtains flight plan data (departure airport, flight number) by interconnecting with the airborne data bus.

[0064] Step 5: Based on the location information, retrieve the parking position information of the departure airport from the airport database to determine the parking position (Y) where the current aircraft is located and the longitude (lon) of parking position Y. y ), latitude (lat y ).

[0065] Step 6: The parking brake needs to be set to OFF before the aircraft is pushed out of the parking position. Therefore, the parking brake position is determined by real-time monitoring of the data on the onboard data bus. If it is in the OFF position, proceed to step 7. If it is in the ON position, repeat step 6.

[0066] Step 7: Determine whether the aircraft has started to push out by monitoring the ground speed information in real time. x >0m / s, proceed to step 8. Otherwise, loop through step 7.

[0067] Step 8: By calculating the distance Z between the position of the aircraft and the position of the parking position in real time, determine whether the aircraft is pushed out of the parking position. The calculation formula is: Z = 2r*arcsin(sqrt(sin^2((lat y -lat X ) / 2)+cos(latx)*cos(lat y )*sin^2((lon y -lon x ) / 2))) Where r = 6371 km. If Z>40 m, proceed to step 9. Otherwise, loop through step 8.

[0068] Step 9: Record the timing information t at this time as the off-block time, and transmit it together with the aircraft identity information obtained in step 2 to the ground information system through the Beidou short message for data distribution.

[0069] The embodiment of the present invention provides a method for acquiring the off-block time. On the one hand, the aircraft position, ground speed information and timing information are acquired in real time by receiving and solving Beidou satellite navigation signals. On the other hand, the aircraft data is directly read and monitored in real time through an airborne bus. An algorithm based on multi-data source judgment is designed according to an actual workflow to complete the autonomous determination and collection of the aircraft's off-block time. Finally, the data is transmitted to a ground information system through a Beidou short message for data distribution. The method has the advantages of being timely, accurate, automated, not affected by external environments such as weather, low implementation difficulty, and easy to promote.
