[0046] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below in combination with the drawings in the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0047] In recent years, the implementation of the RECAT-CN system has achieved some results, and further reduces the interval standard. However, the increasing traffic flow, more complex arrival and departure operation modes and other influencing factors reduce the airport departure efficiency and the workload of controllers, and a new system is urgently needed to reduce the workload of controllers and give the optimal solution of the aircraft departure interval.

[0048] In the original system, the following problems are found to be improved: 1. The original system still mainly relies on the experience of controllers to manage the departure interval of aircraft. Although there is a standard for the departure interval, due to the complexity of airport work and the limitation of human resources, controllers cannot control the departure interval within a small interval standard. If the reaction is not timely, it will cause air traffic accidents. On the other hand, the existing system cannot provide all the required information that affects the departure interval for controllers, so the minimum departure interval standard has little effect on interval management. 2. The current departure interval system only supports single runway departure interval management in a single operation mode, and cannot configure multiple operation modes for multi-runway coordinated departure interval management. This requires controllers to additionally consider the interval requirements when multiple runways are independently operated, which reduces the refinement level of interval management, and controllers still need to perform interval allocation according to the existing standard, which cannot improve the efficiency of airport operation. Long-term monitoring reduces work efficiency and increases the burden of controllers. 3. There is a lack of prediction function. The decision of departure based on a single safety interval is often different from the actual situation. If the prediction function is realized, the departure interval and the predicted departure time of each aircraft are obtained, and the controllers dynamically allocate the departure interval of each aircraft according to the system suggestion to further reduce the subsequent aircraft departure interval to the minimum interval standard, thereby maximizing the efficiency of airport operation.

[0049] Due to the above problems in the current interval management system, it is difficult to improve the efficiency of airport departure. The increasing demand for refined allocation of departure interval and the traditional allocation method have become the main contradiction restricting the improvement of airport operation efficiency.

[0050] In order to solve the problems in the prior art, the present application provides a method for decision-making of departure interval of a departure flight, so as to improve the efficiency of aircraft departure. The method for decision-making of departure interval of a departure flight will be described as follows, Figure 1 、 Figure 2As shown, including but not limited to the following steps:

[0051] Step 110, obtaining the departure procedure parameters and departure strategy parameters of the aircraft to be departed; wherein the departure procedure parameters are obtained through radar monitoring, flight planning system and aircraft communication system, and the departure strategy parameters are obtained through user input.

[0052] In step 110, obtaining the departure procedure parameters and departure strategy parameters of the aircraft to be departed is a key step to ensure the safe and orderly takeoff of the aircraft. The departure procedure parameters include some time data before departure such as push-out time, taxi time, waiting time, and information such as aircraft model, performance and weather information, traffic flow, etc., which are obtained through radar monitoring, flight planning system and aircraft communication system. The departure strategy parameters refer to the takeoff strategy formulated under specific circumstances, such as takeoff sequence adjustment under special weather conditions or priority takeoff of specific flights, or optimization strategies such as minimizing delay and maximizing fuel efficiency, which are obtained through user input to meet the flexible adjustment needs in actual situations and ensure efficient operation of the takeoff process.

[0053] Step 120, inputting the departure procedure parameters and the departure strategy parameters into the queue sorting model to obtain the departure queue information of the aircraft to be departed; the queue sorting model is used to determine the departure order of the aircraft to be departed according to the departure procedure parameters and the departure strategy parameters.

[0054] In step 120, the departure procedure parameters and the departure strategy parameters need to be input into the queue sorting model to obtain the departure queue information of the aircraft to be departed, to ensure orderly departure according to the specified procedure and strategy. The queue sorting model is learned based on historical departure data of the aircraft, can predict the preliminary sorting order, and has dynamic adjustment ability and real-time adaptability; can dynamically adjust the sorting order of the aircraft according to the real-time changing conditions and information, support multi-objective optimization such as minimizing delay and maximizing fuel efficiency. At the same time, it also supports optimization adjustment according to dynamic parameters such as airport traffic and weather conditions, to improve the overall efficiency and safety of the departure sorting.

[0055] Step 130, determining the takeoff interval of the target aircraft according to the departure procedure parameters and the departure queue information.

[0056] The departure procedure parameters include flight plan, airport route, take-off interval standard and the like. According to the parameters, the departure time point and take-off sequence of the target aircraft are determined. The departure queue information includes the sequencing order and the expected departure time of the aircrafts to be departed. According to the information, the position of the target aircraft in the queue and the expected take-off time are determined. In combination with the position of the target aircraft in the queue and the expected take-off time, and the take-off interval standard in the departure procedure parameters, the take-off interval of the target aircraft from the previous aircraft is calculated. The calculation of the take-off interval takes into account safety and operational efficiency, to ensure sufficient time interval between the aircrafts. Preferably, the take-off interval of the target aircraft is dynamically adjusted according to real-time conditions and dynamic parameters (such as weather, airport traffic and the like). Dynamic adjustment can help optimize the take-off process and improve overall efficiency and safety.

[0057] The method for determining the take-off interval of the departure flight provided by the application obtains the departure procedure parameters of the aircraft to be departed through radar monitoring, a flight planning system and an aircraft communication system, and then inputs the departure strategy parameters input by a user. The departure procedure parameters and the departure strategy parameters are input into a queue sequencing model to obtain the departure queue information of the aircraft to be departed. Then, the take-off interval of the target aircraft is determined according to the departure procedure parameters and the departure queue information. By integrating the refined multiple departure operation modes, the departure aircraft queue is optimized according to the departure runway, the departure procedure and the expected departure time, and the take-off interval, the flight speed, the wind speed and the aircraft performance are comprehensively utilized to make a prediction of the take-off interval and the expected take-off time of each aircraft by relying on numerical methods, thereby solving the problem that the existing system lacks fine monitoring and prediction functions for the take-off interval.

[0058] As a further optional embodiment, the departure strategy parameters include weight adjustment parameters and strategy adjustment parameters.

[0059] The weight adjustment parameters are used to adjust the weight of the sequencing factors of the queue sequencing model.

[0060] The strategy adjustment parameters are used to adjust the sequencing strategy of the queue sequencing model.

[0061] In this embodiment, the weight adjustment parameters are used to adjust the weight of the sequencing factors in the queue sequencing model. By adjusting the weight, the importance of different factors can be dynamically adjusted to adapt to the departure requirements under different conditions. For example, the importance of the flight plan can be adjusted according to real-time conditions to better adapt to changes in airport traffic and the like.

[0062] Policy adjustment parameters: used to adjust the ranking strategy of the queue ranking model. By adjusting the ranking strategy, the ranking order of the aircraft can be flexibly adjusted according to different departure requirements and real-time conditions. For example, the ranking strategy can be adjusted during high traffic periods to prioritize high-efficiency flights for takeoff to maximize the operational efficiency of the airport. This embodiment can dynamically adjust the ranking order of the aircraft according to real-time changing conditions and information, support multi-objective optimization such as minimizing delay and maximizing fuel efficiency, and support dynamic parameter optimization of airport traffic, weather conditions, etc. to improve the overall efficiency and safety of the departure ranking.

[0063] As a further optional embodiment, the queue ranking model is obtained by the following steps:

[0064] Building a queue ranking target;

[0065] Obtaining historical ranking data;

[0066] Feature extraction is performed on the historical ranking data to obtain historical ranking vectors;

[0067] According to the queue ranking target and the historical ranking vector, a machine learning model is trained to obtain a queue ranking model.

[0068] In this embodiment, the construction of the queue ranking model can be carried out according to the following steps:

[0069] Problem definition: determine multiple ranking targets, including minimizing delay, maximizing fuel efficiency, etc.

[0070] Data preparation: collect and prepare the aircraft historical ranking data set, including departure procedure parameters and departure queue information.

[0071] Feature engineering: select and construct features for the ranking model. Extract useful information from the original data, convert data formats and create new ranking features such as flight plans, airport routes, etc.

[0072] Model training: train the model using multiple ranking targets, such as integrated multi-objective optimization algorithms or multi-objective ranking models.

[0073] Model tuning: modify feature selection and model parameters according to real-time input data to improve the accuracy and generalization ability of the model.

[0074] Model deployment: integrate the model into an application or service, receive new data in real time and generate aircraft departure ranking results to support real-time aircraft departure management.

[0075] As a further optional embodiment, the step of inputting the departure procedure parameters and the departure strategy parameters into a queue sorting model to obtain the departure queue information of the aircraft to be departed is specifically as follows:

[0076] inputting the departure procedure parameters and the departure strategy parameters into a queue sorting model;

[0077] obtaining the departure queue information of the aircraft to be departed when a target function of the queue sorting model converges, the target function of the queue sorting model being as follows:

[0078]

[0079] wherein n represents the total number of aircrafts to be departed at present; a0 represents the departure time of the aircraft just taking off; t0 represents the departure time of the flight currently on the runway; ti represents the departure time of the i-th aircraft to be departed; and t n represents the departure time of the last aircraft on the departure runway.

[0080] In this embodiment, a target function of the total value of departure time consumption of the aircrafts to be departed is established to meet the minimum delay priority. The target function is as follows:

[0081]

[0082] Generally, all adjacent departure aircrafts need to meet a specific departure interval, which includes a release interval and a wake interval. Meanwhile, in order to meet the minimum total value of departure time consumption, the aircrafts will take off continuously without special circumstances, and the target function will be further revised as follows:

[0083]

[0084] σ i，i+1 = max(X i，i+1 y i，i+1 )

[0085] wherein σ i,i+1 is the minimum time interval between the i-th aircraft and the i+1-th aircraft, x i,i+1 is the release interval, and y i,i+1 is the wake interval.

[0086] As a further optional embodiment, the departure queue information includes a departure interval time and departure sorting information, and the step of determining a take-off interval of a target aircraft according to the departure procedure parameters and the departure queue information specifically includes:

[0087] determining the departure procedure parameters and the departure interval time corresponding to the target aircraft according to the departure sorting information;

[0088] determining a preceding aircraft departure trajectory according to the departure procedure parameters and the departure separation time;

[0089] determining a take-off separation of the target aircraft according to the preceding aircraft departure trajectory.

[0090] In this embodiment, the safe take-off separation and the reasonable take-off separation are generated according to the wake separation of the paired aircraft type and the aircraft performance model, and the aircraft departure speed profile is also introduced. Specifically, given two parameters in the speed distribution v(x) of the aircraft departure process, the position x1, the final position x2 and the movement time T, the third parameter can be solved. Let the required departure separation be S i , the required take-off separation be S j , the ground speed distribution of the preceding aircraft and the following aircraft be v f (x), v b (x), the real-time position of the preceding aircraft be x f1 , the real-time position of the following aircraft be x b1 , the preceding aircraft satisfy the take-off separation of the following aircraft, the position of the preceding aircraft be x f2 =S j , and the position of the following aircraft be x b2 . It is easy to obtain:

[0091] S i =x f1 -x b1

[0092] S l =x f2 -x b2 =x f1 -x b1 -x b2

[0093] The ideal trajectory prediction calculation method of the preceding aircraft departure is as follows:

[0094] According to the take-off separation of the following aircraft and the aircraft departure speed distribution, the flight time of the preceding aircraft can be calculated:

[0095]

[0096] wherein n is an integer constant.

[0097] According to the isochronism, the distance of the preceding aircraft flying after T time is:

[0098]

[0099] The ideal departure trajectory prediction system predicts the ideal position of the preceding aircraft on the departure procedure based on the preceding aircraft's departure procedure and flight distance. Each trajectory signal predicts an ideal position. Based on the digitized departure procedure and aircraft performance model, the system extracts the aircraft's four-dimensional trajectory data and uses time slicing to predict the aircraft's ideal trajectory on the departure procedure.

[0100] For two aircraft following each other before and after departure, the estimated takeoff interval between the two aircraft can be calculated based on their speed distribution and actual positions.

[0101] The required takeoff interval S for the following aircraft is known j , the real-time position of the preceding aircraft x f1 , the real-time position of the rear aircraft x b1 , then the real-time interval between the two machines is S r for:

[0102] S r =|x f1 -S j -x b1 |

[0103] The estimated takeoff intervals are:

[0104] S y =x f1 -S r

[0105] Using the formula:

[0106] T y =V b (S y )-V b (s r )

[0107] The feature of the estimated takeoff interval prompt is that the estimated takeoff interval in distance form can be converted into the estimated takeoff interval in time form, where V(x) is the original function of v(x).

[0108] By the formula:

[0109]

[0110] Right now:

[0111] T i =V f (x b1 )-V f (x b1 -s r )

[0112] As a further optional embodiment, after the step of determining the takeoff interval of the target aircraft based on the departure procedure parameters and the departure queue information, the decision-making method further includes:

[0113] When the takeoff interval is less than a preset threshold, interval warning information is generated, and the interval warning information is used to remind the user.

[0114] In this embodiment, when the predicted takeoff interval is less than the required takeoff interval threshold, that is:

[0115] S y ≤S j

[0116] An interval warning message is generated.

[0117] As a further optional embodiment, after the step of determining the takeoff interval of the target aircraft based on the departure procedure parameters and the departure queue information, the decision-making method further includes:

[0118] Determine a take-off time for a subsequent aircraft based on the take-off interval and the departure queue information.

[0119] Specifically, the estimated takeoff time of the subsequent aircraft is calculated based on the takeoff interval and the estimated takeoff time of the preceding aircraft. The calculation of the takeoff interval must take into account safety spacing and airport operational efficiency to ensure sufficient time between aircraft. The calculated estimated takeoff time of the subsequent aircraft is updated in the departure queue information. Based on the updated departure queue information, the takeoff time of the following aircraft is determined. The takeoff time of the following aircraft must take into account the takeoff time and takeoff interval of the preceding aircraft to ensure safe spacing between aircraft.

[0120] The following describes the decision-making device for the departure interval of departing flights provided by the present invention.
