Generally, the aircraft travels on land routes such as airport runways and taxiways before and after takeoff and landing. The pilots are informed and guided by the control system of the airport control center when driving the ground route of the aircraft. However, since the reliance on the guidance of the airport control center may be insufficient, pilots usually use the airplane There are many cases in which a ground route is learned beforehand and a ground route before and after takeoff and landing is prepared.

However, due to various reasons such as airport expansion, maintenance, and repair as well as emergency situations, the ground route of the airport may be changed temporarily or semi-permanently. At this time, if the information provided by the airport or the information provided by the pilot community can not be updated quickly, the pilot may be exposed to information that does not reflect the recent ground route change at the airport.

1 is a block diagram for explaining an aircraft operation support apparatus according to an embodiment. In one embodiment, the aircraft navigation support apparatus 100 may include a first database 110, a second database 120, an abnormal event detection unit 130, and an abnormal event processing unit 250.

Hereinafter, the proposed embodiment will be described focusing on the ground path running of the aircraft, but the embodiment should not be construed as limited to the limited application of the ground path running of the aircraft. For example, the embodiment can be used for flight support in an airplane in flight or an airplane being taken off or landing, and can also be applied to a device or a transportation device having a designated movement pattern other than an airplane.

In general, an aircraft pilot prepares for flight operations by studying in advance the runways and taxiways of the airports scheduled for takeoff or landing for safe flight. However, if an aircraft pilot receives information about an airport's ground path through an airport or other community for pre-flight learning, it is possible that the information provided does not accurately reflect the recent land route changes at the airport, After the learning, additional variations in the ground path may occur due to various causes.

On the other hand, by collecting movement trajectories of a plurality of user terminals and analyzing the movement paths of a plurality of aircraft accumulated in real time through the aircraft operation support apparatus 100 according to an embodiment, the ground path of the airport, It can be provided to the user terminal accurately and conveniently.

In one embodiment, reference trajectory data of the aircraft may be stored in the first database 110 of the aircraft navigation support apparatus 100. The reference trajectory data may include information about the trajectory of the aircraft while the aircraft is moving on the designated path. That is, the reference sign data may include information on the route designated by the aircraft to be moved during normal times when no emergency occurs.

Reference locus data may be generated and provided by, for example, an air traffic control center at an airport, and the format or transmission method of data may be adopted in any suitable manner. The reference trajectory data may include information about each of a plurality of paths through which the aircraft may move but may alternatively or additionally include information about one trajectory incorporating all possible physical traverses of the aircraft.

In one embodiment, movement trajectory data of a plurality of user terminals may be stored in the second database 120 of the aircraft operation support apparatus 100. A user terminal is a portable terminal having a communication function capable of connecting to a network, and may be any suitable dedicated device or a combined device. In a preferred embodiment, the user terminal may be a smartphone or tablet computer, and the aircraft navigation support device 100 may be a server providing services.

In one embodiment, the movement locus data of the user terminal may be generated through location tracking using, for example, a Global Positioning System (GPS) receiver included in the user terminal and stored in the local memory of the user terminal. The movement trajectory data of the user terminal stored in the local memory of the user terminal may be transmitted to the aircraft operation support apparatus 100 if the user terminal can access the network.

In one embodiment, the user may send some or all of the movement trajectory data stored in the local memory of the user terminal to the aircraft navigation support apparatus 100 to determine whether to share the movement trajectory data with other users. In general, it may not be important which user terminal's moving trajectory relates to when the moving trajectory data of the user terminal is used for validating the latest moving path. Accordingly, the moving locus data can be processed anonymously, but the information of the user terminal can be delivered to the aircraft operation support apparatus 100 and / or other users for service improvement or other necessity.

In one embodiment, the abnormal event detection unit 130 detects anomaly event (i.e., anomaly event) in the moving sign data based on the reference sign data stored in the first database 100 and the moving sign data of the plurality of user terminals stored in the second database 120 abnormal events can be detected.

Specifically, when the reference sign data includes information on the trajectory of the aircraft moving along the designated guide path of the airport, the abnormal event detection unit 130 detects the reference sign data and the reference sign data for each of the movement sign data of the plurality of user terminals. And identifies a case in which at least a part of the movement locus data is different from the reference locus data as an abnormal event. The similarity degree between two locus data can be determined when the matching between the moving locus data and the reference locus data is confirmed and the degree of similarity for determining whether to match or not can be set differently according to the matching accuracy required in design.

In one embodiment, when an anomaly event is detected, the anomaly event detector 130 may generate anomaly event information including time information on which the corresponding trajectory data is generated. The anomaly event may refer to a case where an aircraft has departed from a designated route, which includes not only when a particular aircraft leaves the route due to a mistake of the pilot or a malfunction of the apparatus, but also when the designated route is temporarily or semi-permanently changed . The abnormal event detection unit 130 may analyze the movement trajectory data of the accumulated user terminals to determine whether the detected abnormal event is a case where the specific airplane has deviated from the route or the designated route has been changed.

As a specific example, if an abnormal event occurs due to continuous movement trajectory data continuously following the movement trajectory data at the time when the anomaly event first occurred, it can be determined that the designated path has been changed. In this case, since it means that the real-time fluctuation of the designated path is not reflected in the reference trajectory data, it is preferable to provide the information of the changed path to the users and proceed the subsequent process of correcting the reference trajectory data.

In one embodiment, the anomaly event processing unit 140 may transmit the anomaly event to the user terminal so that the users receive information on the changed path in real time. In addition, the anomaly event processing unit 140 may transmit the anomaly event to the provider of the reference sign data (for example, the airport control center) to request the update of the reference sign data.

In one embodiment, a method of reducing the location sampling frequency of a user terminal under certain conditions may be considered to reduce the amount of data and power consumption when generating motion locator data at the user terminal.

For example, if the position of the user terminal is not changed for a long time, even if the position sampling frequency is decreased, the accuracy of the movement locus data is not greatly affected. Therefore, The location of the user terminal may be sampled. When the position of the user terminal starts to change, the position of the user terminal can be sampled according to the reference frequency again.

Likewise, even if at least one of the aircraft's heading, elevation and speed does not change for a predetermined time, the location sampling frequency may be reduced to store the location of the user terminal at a frequency that is less than the reference frequency. In this case, when the radar direction, altitude, and speed of the aircraft start to change, the position of the user terminal may be sampled again according to the reference frequency.

2 shows an exemplary airport runway and guideway for illustrating operation of an aircraft operation support apparatus according to an embodiment. Generally, the ground transportation routes of airplanes such as runways and induction routes have different shapes for each airport, and connection routes to places where airplanes such as hangars wait are also different from each other.

The runway and guideway shown in Fig. 2 illustratively show a general ground movement path for explanation purposes, and the embodiment is not limited by the form of such runway and guideway.

Specifically, the airport may include one or more runways 210, 220. Typically, around the runways 210 and 220, an induction passage is disposed for ground connection of the aircraft and for connection with other facilities in the airport. For example, an entrance taxiway, a parallel taxiway, a bypass taxiway, and a rapid exit taxiway may be arranged around the runway.

The reference trajectory data formed on the runway and the guide path and the movement trajectory data of the user terminal will now be described in more detail with reference to Figs. 3 to 5.

FIG. 3 is a view for explaining the operation of an aircraft operation support apparatus according to an embodiment. In FIG. 3, exemplary reference sign data 310, 320 are shown.

For example, the first reference locus data 310 may be a ground travel path designated by the airport control center for an aircraft to take off using the first runway 210. Also, the second reference sign data 320 may be a ground movement route designated by the airport control center for an airplane to land using the second runway 220.

The reference locus data 310, 320 may be provided by an airport control center or the like and may have the form of a trace of a set of single travel routes or an allowed travel route. The manner of storing and reading the reference locus data may be selected in any suitable manner.

It is often desirable that the reference trajectory data be updated with the latest information from the data provider, but in actual situations it often happens that the latest changes being applied to aircraft currently in take-off and landing at the airport are not reflected. In this case, communication with the airport control center can be informed about the change. However, if the pilot confirms the change in the ground travel route in advance or confirms it in real time and receives the guidance from the airport control center, It is expected that the operation will be possible.

4 is a view for explaining an operation of an aircraft operation support apparatus according to an embodiment. FIG. 4 shows movement trajectory data 410, 420 of an exemplary user terminal.

For example, the first movement sign data 410 and the second movement sign data 420 may be a movement trajectory of a user terminal carried by a pilot or the like aboard the aircraft taking off using the first runway 210 .

The movement trajectory data of the user terminal may be generated through location tracking using a GPS receiver included in the user terminal as described above with reference to FIG. In the environment where the user terminal can not access the network, the movement locator data is first stored in the local memory of the user terminal, and thereafter, the movement locator data of the user terminal in the environment where the user terminal can access the network To the collecting server.

4, the first moving sign data 410 can be matched with a part of the first reference sign data 310, but the second moving sign data 420 has a different trajectory than the reference sign data have. For example, the second movement sign data 420 may correspond to a case where a change in the ground movement path occurs due to a temporary change in the hangar of the aircraft. In this case, since the second movement locus data 420 does not include the reference locus data to be matched, it can be regarded as movement locus data for generating an abnormal event.

When an abnormal event is detected in a part of the collected movement trajectory data, it is determined whether or not it is an abnormal event that can be regarded as a variation of the ground path due to a continuous occurrence of an abnormal event occurring one time, To the pilot in operation or to the provider of the reference trajectory data.

5 is a view for explaining an operation of an aircraft operation support apparatus according to an embodiment. FIG. 5 illustrates an example of a function of a user, such as a pilot, in a user terminal to leave a note on an abnormal event.

For example, an interface may be provided that allows a user to leave a memo 520 for an anomaly event experienced at a particular location indicated by the location indicator 510. [ The memo 520 may be recorded together with the abnormal event occurrence date and time, and may be shared with other users and / or reference sign data providers according to the setting of the user.

In this way, the aircraft operation support device is capable of real-time abnormal event detection and information sharing through the user's memo, so that the pilot who is learning in advance about the ground route of the airport or the pilot who is currently operating the aircraft in the ground route of the same airport, Information can be provided, which can greatly contribute to the stability of aircraft operation.

Further, since the reference sign data can not be updated in a timely manner, the reference sign data provider can be prompted to update the reference sign data, thereby improving the safety of the aircraft operation.

FIG. 6 is a flowchart illustrating an aircraft operation support method according to an embodiment. The method of supporting an aircraft operation of Fig. 6 may be, for example, a method using an aircraft operation support apparatus shown in Fig.

At step 610, movement trajectory data of the user terminal may be collected. For example, the server can receive the mobile locus data generated by sampling the location of the user terminal periodically at a user terminal owned by a plurality of subscribers using the aviation service, and store the received locus locus data in a database. As described with reference to Figure 1, the sampling frequency of the user terminal may be variably set under certain requirements.

At step 620, reference trajectory data of the aircraft may be received. Reference trajectory data may include information about the trajectory of the aircraft while the aircraft is moving along the designated path, and is typically generated and provided by an air traffic control center or the like. The server may receive the reference locus data in any suitable manner and store it in the database.

In step 630, it is possible to detect an abnormal event in the moving locus data based on the moving locus data and the reference locus data. Specifically, it is possible to identify whether each of the movement trajectory data of the plurality of user terminals is matched with the reference trajectory data, and identify a case where at least a part of the movement trajectory data is different from the reference trajectory data, as an abnormal event. The similarity degree between two locus data can be determined when the matching between the moving locus data and the reference locus data is confirmed and the degree of similarity for determining whether to match or not can be set differently according to the matching accuracy required in design.

In step 640, the anomaly event may be communicated to at least one of the provider of the reference locus data and the user terminal. When the anomaly event is delivered to the provider of the reference sign data, it is possible to request the update of the reference sign data. When the abnormal event is transmitted to the user terminal, the users can receive the information of the changed path in real time.

As described above, according to the proposed method, it is possible to detect the occurrence of an abnormal event in the movement trajectory of the aircraft such as the ground movement path of the aircraft in real time, and to quickly improve the safety of the aircraft by feeding back to the user and the manager. In addition, by providing an interface for individual users to leave notes or share notes about anomalous events, a user such as a pilot can quickly identify comments on major changes, which can be of practical assistance to aircraft operation.
