It relates to a method and apparatus for automatically generating a trajectory-based aircraft traffic management message that can be utilized as a system.

Existing air route traffic control is based on the flight plan submitted by the controller in advance and the current status information such as track showing information such as the current position and speed of the aircraft in real time, and judges the safety of the aircraft and the efficiency of the traffic flow. The situation is giving control orders.

In such air route traffic control, as a control order made under the subjective judgment of human beings, there were many tactical instructions mainly for a short-term from the present, while the overall flow of aircraft traffic and the entire flight cycle. Consideration was not easily made.

In recent years, due to the development of aviation surveillance/communication/navigation technology, it is now possible to exchange more accurate and various types of aircraft information with ground controllers.

In the tracking of the trajectory, the generation unit 110 considers the speed/altitude at which the aircraft is flying, the surrounding weather/climate change, altitude, air density, etc., and information provided from the aircraft on the trend line of the trajectory of the past flight. By predicting the trajectory that the aircraft will fly using, the trajectory can be tracked.

According to an embodiment, the generation unit 110 provides flight intent information including an EPP (Expended Projected Profile) and a speed schedule, and ADS-C (Automatic Dependent Surveillance-Contract) communication. Can be received from the aircraft through.

In addition, the scheduling unit 120 schedules an operation plan of the plurality of aircraft on the air route by using the first trajectory information. The scheduling unit 120 may compare the trajectory information generated for a plurality of aircrafts using a common air route, and may adjust a schedule for each aircraft in consideration of the risk of collision between the plurality of aircraft.

In the scheduling of the flight plan, the scheduling unit 120 may schedule the flight plan while considering that the generated first trajectory information does not overlap each other within a certain time interval, between a plurality of aircraft.

If the first trajectory information overlaps each other, the scheduling unit 120 considers the priority for each aircraft (e.g., a priority for an aircraft with a high speed, a priority for an aircraft with a large number of passengers). You can schedule a flight plan that adjusts the aircraft's speed, altitude, and transit points.

The processing unit 130 creates a control message related to the scheduled flight plan and provides it to each of the plurality of aircraft. That is, the processing unit 130 may serve to create a control message by texting the flight plan, and transmit it to the aircraft so that it is displayed on the information display terminal in the aircraft.

The control message may be a detail of information transmitted through a data communication network between an aircraft and an air traffic facility (a route control station, an access control station, etc.), and in the present invention, it may be created by reflecting a flight plan according to an estimation of the trajectory of the aircraft. This information can also be provided to the controller so that the controller can reflect this and decide whether to apply the control instructions directly to the aircraft.

According to an embodiment, the processing unit 130 creates a flight path in consideration of at least one of a location, altitude, speed, and arrival time for the aircraft, and includes it in the control message, and provides it to the aircraft. I can. That is, the processing unit 130 may determine the most desirable flight path by estimating the trajectory from the trajectory according to the past flight of a specific aircraft, and provide this as a control message to the aircraft.

The monitoring unit 140 may monitor a degree of proximity between the plurality of aircraft on the air route using the first trajectory information. That is, the monitoring unit 140 may observe the proximity degree between aircraft that are close to each other according to the first trajectory information.

Thereafter, the processing unit 130 may select a dangerous aircraft in which the monitored proximity degree reaches a set risk value, among the plurality of aircraft, and create a warning message, and provide the selected dangerous aircraft. That is, the processing unit 130 may select an airspace where a collision risk is expected because the proximity degree is too small, as a dangerous aircraft, and transmit a related warning message.

The warning message includes information on the speed and direction of flight of other aircraft approaching the dangerous aircraft, the predicted collision time, and the predicted impulse point, and also includes a countermeasure (speed reduction, altitude reduction, etc.) for collision avoidance. I can.

According to an embodiment, the automatic message generating apparatus 100 of the present invention may perform a function of warning about an aircraft that deviates from a pre-planned route.

To this end, the automatic message generating apparatus 100 of the present invention may be configured to further include a collection unit 150. The collection unit 150 may collect flight track information and setting information applied to scheduling from the flight information manager. That is, the collection unit 150 may function to receive information on scheduling settings. Here, the aviation information manager may be a means for registering and managing various types of information on a scheduled flight or an in-flight aircraft, and the collection unit 150 may serve to receive flight track information on a route of the aircraft.

Thereafter, the processing unit 130 selects an aircraft in which the position of the aircraft according to the first trajectory information is out of the range selected from the position of the aircraft according to the flight track information and does not match, as a dangerous aircraft, and generates a warning message. It can be prepared and provided to the selected dangerous aircraft.

According to an embodiment, the message automatic generating device 100 of the present invention may provide a message for stably controlling the unmanned aerial vehicle by determining whether an unmanned aerial vehicle such as a drone can collide with another aircraft.

To this end, the apparatus 100 for automatically generating a message according to the present invention may be configured to further include a search unit 160. If the aircraft is an unmanned aerial vehicle, the search unit 160 retrieves, from an aviation information database, at least one of polygonal boundary point information, altitude range information, and occupancy time information, about the airspace area in which the unmanned aerial vehicle flies. You can search. That is, the search unit 160 may play a role of searching for region information of a three-dimensional space in which the unmanned aerial vehicle is flying.

In addition, if the aircraft is a manned aircraft, the search unit 160 may check EPP, speed schedule, etc. provided through ADS-C or search for information on a trajectory including generated trajectory information and scheduling results.

The boundary point information may refer to information on an arbitrary point in a three-dimensional space designated for the unmanned aerial vehicle to pass through, and the altitude range information is the maximum height that the unmanned aerial vehicle can reach and the minimum height that must be maintained at least for stability. Can refer to information. In addition, the occupancy time may refer to information on an allowable time for a specific unmanned aerial vehicle to maintain flight in a corresponding three-dimensional space.

Thereafter, the processing unit 130 may determine whether the unmanned aerial vehicle is stable with other aircraft using the area information. That is, the processing unit 130 may determine the possibility of a collision with another aircraft that is already flying within the area in which the unmanned aerial vehicle is flying, or with another aircraft that is approaching into the area.

The processing unit 130 may create a control message for controlling the unmanned aerial vehicle according to a result of determining stability with other aircraft and provide it to the unmanned aerial vehicle. Through this, the unmanned aerial vehicle can provide an environment in which it can fly while securing stability within a specific area.

According to an embodiment, the message automatic generating device 100 of the present invention estimates a trajectory according to the change for a specific aircraft requesting a flight change, compares it with the trajectory of other aircraft, and makes the change when there is no possibility of collision. You can allow it.

To this end, when a flight change request is received from an aircraft, the generation unit 110 may generate second trajectory information by estimating a trajectory for the arbitrary aircraft. That is, the generation unit 110 may play a role of newly generating trajectory information in consideration of a route to be changed for any aircraft requiring route adjustment.

It is possible to provide a method and an apparatus for automatically generating a.

In addition, according to an embodiment of the present invention, for an aircraft that has requested a change in flight path due to climate change, etc., by estimating the trajectory of the corresponding aircraft and predicting the risk of collision with other aircraft, a stable flight path change is possible. It is possible to provide a method and apparatus for automatically generating an aircraft traffic management message based on a trajectory to be achieved.

2 is a flowchart for processing a trajectory-based navigation (TBO) service according to the present invention.

Currently, it is in the stage of establishing an operating concept for trajectory based operations (TBO) around the world, and identifying/development of available technologies. However, until now, the research is limited to the operation method using the trajectory information, and there has not been established on the concept of the control operation for the entire trajectory of the aircraft and the system that automatically generates the control message by applying it.

The automatic message generation device of the present invention automatically generates and provides the trajectory-based control information as a Controller Pilot Data Link Communication (CPDLC) message through scheduling/monitoring by predicting the entire trajectory of an aircraft flying in the airway area in real time. .

In order to clarify the operational concept of a method of providing a trajectory-based control service, a flow chart of a service processing method from service start to end is established in FIG. 2.

As shown in Fig. 2, in each sequence, data and processing methods exchanged between the control system and the aircraft are included.

First, when the initiation of the invention occurs in Action 1, in Action 2, the message automatic generating device of the present invention and the trajectory of the aircraft are synchronized (Synchronization). Here, the trajectory synchronization means matching the flight trajectory that the aircraft intends to fly with the trajectory predicted on the ground, and may refer to a process for matching the trajectories with the utmost precision.

If synchronization is normally performed in Action 2 and a separate change procedure is not required, in Action 3, a clearance procedure can be generated, so that a continuous monitoring operation for the aircraft can be performed in Action 7 (Conformance Monitoring). .

If it is determined that the change is necessary during the flight permitted in Action 3, the permission for the change is requested again in Action 6 (Request Clearance), and it returns to Action 2.

If synchronization is normally performed in Action 2 and it is determined that a separate change procedure is necessary, trajectory negotiation can be performed in Actions 4 and 5 (Trajectory Negotiation). That is, in Action 4, it is possible to negotiate the path of the aircraft (Path Negotiation), and in Action 5, it is possible to perform the negotiation for time (Time Negotiation). When the negotiation is completed, it returns to Action 2 to synchronize the changed trajectory.

In Action 8, as the trajectory-based control service is normally terminated, the trajectory-based navigation (TBO) service processing is terminated (Termination).

In addition, if a normal procedure is not performed in Action 3 or 8, after'Service Out', it can return to Action 6 (Request Clearance).

Accordingly, the apparatus for automatically generating a message according to the present invention can predict a trajectory in the ground control system according to the identified operation concept, and automatically generate and provide a control message through scheduling and monitoring in an automated manner.

3 is a diagram illustrating a software configuration and main data relationships according to the present invention.

The control instruction can be transmitted and received through a CPDLC method based on a standardized message format. Among them, if a message type capable of expressing an aircraft path such as Message ID “UM83R” is used, in the present invention, the control instruction is more extensive and It can be expressed in various forms of flight. At this time, “UM83R” refers to the CPDLC message ID described in RTCA DO-351 (Interoperability Requirements Standard for Baseline 2 ATS Data Communications, Baseline 2 Interop Standard, Initial release, 2014.3.18), and the message ID or format is different. You can also choose to use it.

Since this has a standardized data format, it may be applicable by directly inputting the flight instruction to the FMS (Flight Management System) that controls the flight of the aircraft without the pilot directly inputting the flight instruction.

Therefore, according to the present invention, it is possible to request and permit a more complex and various types of control.

When complex navigation with an unmanned aerial vehicle is possible, the trajectory information of the unmanned aerial vehicle is expressed as an area for automatic control processing, so that the control process can be carried out in consideration of the complex environment in which the unmanned aerial vehicle and the manned vehicle are combined to navigate.

As shown in Figure 3, the software, Codec (310), Flightinfo Manager (320), Trajectory Predictor (340), Scheduler (360), Monitor (370), consisting of five CSU (Computer Software Unit). I can.

Codec 310 may encode and decode'Flight Plan, Track, ADS-C DM/UM, CPDLC DM/UM, Message to CWP', etc. according to a defined protocol format.

The Flightinfo Manager 320 may update and manage each information for each aircraft.

Trajectory Predictor 340 may implement a trajectory of an aircraft based on EPP for each aircraft, track, etc. in the Flightinfo DB 330. The implemented trajectory information may be stored/managed in the “Trajectory DB 350”.

The scheduler 360 and the monitor 370 may process scheduling and monitoring information necessary for control, respectively, using the trajectory information.

If necessary, the Flightinfo Manager 320 may generate a control message and transmit the control message to the outside through the Codec 310.

In order to create a precise trajectory, flight intent information including EPP, speed schedule, etc. can be received as a 1:1 information request and response with the aircraft through ADS-C communication.

The message for control instruction uses a standardized format in CPDLC Uplink Message (UM). In particular, if you use “UM 83R” to change the route for all flight sections, various types of flight routes can be expressed by combining information such as location, altitude, speed, and arrival time. Accordingly, according to the present invention, it is possible to improve the situation awareness of the pilot's control instruction by providing information on the entire flight path rather than a temporary path change.

In one embodiment, the pilot may request permission for a flight change in real time according to bad weather, emergency situations, economic effects, and preferences, which may be transmitted in the form of a CPDLC Downlink Message (DM). In particular, in the case of requesting permission for the entire path, in the present invention, Message ID “DM 24” or the like may be used.

When such a request is made, the control system can predict the revised trajectory to determine whether there is a problem, and provide the result through the CPDLC UM.

In addition, responses and negotiations for control between the control system and the pilot can be handled through CPDLC UM/DM.

In the case of an unmanned aerial vehicle, it is also possible to perform a control service for a specific area other than a route.It is a method of determining whether or not stability with other aircraft is provided by providing polygonal boundary points, altitude range, and occupancy time information to the unmanned aerial vehicle. This can be done by issuing and monitoring flight permits.

In addition, the control system can provide the control result to the controller, if necessary, in the form of advice information that the controller can refer to. Here, the provided information may include a control message or trajectory prediction information.
