Title: Arrival information providing method, server and display device

Description:
TECHNICAL FIELD 
     Example embodiments relate to an arrival information providing method and server, and a display device. 
     BACKGROUND ART 
     An airplane may arrive at a destination behind an expected arrival time because the airplane may be grounded or delayed due to adverse weather conditions or congested traffic around an airport. Thus, a person who waits for a passenger of the airplane to meet the passenger at an arrival exit gate of the airport may need to wait an arrival of the passenger even after the expected arrival time of the airplane. 
     After the arrival of the airplane, the person may need to wait for the passenger to arrive at the arrival exit gate for about 30 minutes or more than 2 hours. Thus, there may be a wide variation in waiting time. In addition, the person may not estimate an accurate time at which the passenger is to arrive at the arrival exit gate based on the arrival time of the airplane, and thus the person may experience inconvenience because the person needs to wait at the arrival exit gate until the passenger arrives at the arrival exit gate. 
     An airplane arrival announcing device may provide information about an airline, a flight number, an expected airplane arrival time on schedule, a point of departure, and an arrival time of the airplane at which the airplane lands, and information as to whether the airplane arrives at an airport, or is delayed or canceled. 
     However, a person who waits for a passenger of an airplane to meet the passenger may not obtain sufficient information only from the airplane arrival announcing device, and also not move to another place until the passenger appears at an arrival exit gate of an airport at which the airplane arrives. In addition, the person may waste time by waiting until the passenger appears at the arrival exit gate. 
     Furthermore, for example, in a case that a person who goes to an airport to pick up a guest for an important business task is out of an arrival exit gate of the airport for a short time for some personal errands and, meanwhile, the guest comes out the arrival exit gate, and thus the person and the guest miss each other and do not meet each other, the person may sustain a serious loss in business. 
     Thus, there is a desire for a service model that may provide arrival information of an airplane and a passenger of the airplane to an airport user or a person who goes to the airport to pick up and wait for the passenger at an airport at which the airplane is to arrive.

     BEST MODE FOR CARRYING OUT THE INVENTION 
     Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present disclosure by referring to the figures. 
       FIG. 1  is a flowchart illustrating an arrival information providing method according to an example embodiment. 
     The arrival information providing method to be performed by an arrival information providing server may be divided into the following operations. 
     In operation S 101 , the arrival information providing server receives airplane information from an airplane information managing server of an airport at which an airplane is to arrive. 
     The airplane information managing server may be at least one of a flight information server, an air control server, or a ground control server. The airplane information managing server may manage an airplane flight number, airplane location information, and estimated location information including airplane landing at an airport, and an apron of the airport apron at which the airplane is parked. 
     The flight information server may be connected to a database configured to collect airplane flight information, and used to manage daily flight information of each airplane. In addition, the flight information server may interwork with airport facilities to control airport equipment. 
     The air control server may be connected to an air traffic control radar to transmit and receive airplane information. The air control server may support a safe flight or navigation of an airplane both in the air and on the ground. In addition, the air control server may maintain desirable air traffic, and support an airfield control task, an access control task, and an airway control task based on a task range and a characteristic of each step of flight. 
     The ground control server may be connected to a ground traffic control radar to transmit and receive airplane information. In addition, the ground control server, which is an integrated ground control system configured to detect, guide, and control airplanes and various support vehicles moving on runways or taxiways using radars and light controllers installed at an airport, may support a safe flight or navigation of an airplane. 
     In operation S 102 , the arrival information providing server determines an actual airplane arrival time at which the airplane is to arrive at an apron of the airport. 
     Here, the actual airplane arrival time at which the airplane arrives at the apron may be determined using a landing time of the airplane at which the airplane lands on a runway of the airport and a time used for the airplane to move from the runway to the apron. 
     The time used for the airplane to move from the runway to the apron may be determined based on at least one of an apron allocation time for the airplane or an estimated airplane movement time used for the airplane to move from the runway to the apron. 
     In operation S 103 , the arrival information providing server calculates a passenger movement time from the actual airplane arrival time to a time at which a passenger of the airplane arrives at an arrival exit gate of the airport. 
     In operation S 104 , the arrival information providing server determines an expected passenger arrival time based on the actual airplane arrival time and the passenger movement time. 
     The expected passenger arrival time may be determined based on sensor information received from a sensor located on a passenger movement route from the apron at which the airplane is parked to the arrival exit gate of the airport. 
     The sensor information may include passenger image information obtained by capturing a passenger image using an image capturer located on the passenger movement route. The sensor information may also include passenger identification information obtained by reading a passport, an identification card, a boarding pass, and an identification tag of the passenger. 
     The passenger movement route may include at least one of the apron, an entry gate, a quarantine station, an immigration checkpoint, a carousel, a customs inspection station, or an escalator. 
     In a case that the apron at which the airplane is parked is connected to a boarding bridge, the expected passenger arrival time may be determined based on length information of the boarding bridge. In addition, in a case that the apron at which the airplane is parked is a remote area, the expected passenger arrival time may be determined based on distance information associated with a distance from the remote area to an airport terminal. 
     In addition, the expected passenger arrival time from a current point in time may be determined based on a previously calculated expected arrival time used for the passenger to move from the apron to the arrival exit gate. For example, in a case that the arrival information providing server receives failure occurrence information from a sensor at the airport, the expected passenger arrival time may be determined using a previously calculated average passenger movement time used for a passenger to move from an apron identical to the apron at which the airplane is parked to an arrival exit gate identical to the arrival exit gate of the airport. 
     In operation S 105 , the arrival information providing server provides the actual airplane arrival time and the expected passenger arrival time to an arrival information providing display device. 
     According to an example embodiment, guidance information or advertisement information may also be provided to the arrival information providing display device. 
     For example, based on a preset period and area, the arrival information providing display device may be supported to display an airplane location image, a passenger location image, and the guidance information or the advertisement information. 
     According to an example embodiment, the arrival information providing method to be performed by the arrival information providing server may further include the following operations. 
     First, the arrival information providing server receives airplane location information from the airplane information managing server. 
     Subsequently, the arrival information providing server provides the airplane location image including the airplane location information to the arrival information providing display device. 
     The airplane location information may include location information of the airplane located in the air near the airport. In addition, the airplane location information may include realtime location information of the airplane located on the ground of the airport including the runway or a gate of the airport. 
     According to an example embodiment, the arrival information providing method to be performed by the arrival information providing server may further include the following operations. 
     First, the arrival information providing server receives passenger location information from the sensor located on the passenger movement route from the apron at which the airplane is parked to the arrival exit gate of the airport. 
     Subsequently, the arrival information providing server provides the passenger location image including the passenger location information to the arrival information providing display device. 
       FIG. 2  is a conceptual diagram illustrating an entire arrival information providing system according to an example embodiment. 
     Referring to  FIG. 2 , an entire arrival information providing system includes a flight information server  210 , an air control server  220 , and a ground control server  230 , which are an airplane information managing server, and an arrival information providing server  240  and an arrival information providing display device  250 . 
     As necessary, the airplane information managing server may include one or a plurality of the flight information server  210 , the air control server  220 , and the ground control server  230 . Also, the airplane information managing server may be a server configured to include airplane information and manage the information using a database. However, the airplane information managing server is not limited to the example server described in the foregoing. 
     The flight information server  210 , the air control server  220 , and the ground control server  230  may communicate with the arrival information providing server  240  through wired or wireless communication. The arrival information providing server  240  may receive airplane information from the flight information server  210 , the air control server  220 , and the ground control server  230 . 
     The airplane information received from the flight information server  210  may include, for example, a daily schedule of each airplane, an expected arrival time on the schedule, a flight number, an airline, and a point of departure. In addition, the airplane information received from the air control server  220  and the ground control server  230  may include, for example, a current location, a velocity, a speed, and an altitude of an airplane. However, the airplane information is not limited to the examples described in the foregoing. 
     In addition, the arrival information providing server  240  and the arrival information providing display device  250  may communicate with each other, and the arrival information providing display device  250  may receive arrival information from the arrival information providing server  240 . The arrival information providing display device  250  may receive, as the arrival information, an expected airplane arrival time and an expected passenger arrival time and display a changed time or a passenger appearing time, or a passenger out time. However, examples are not limited thereto. 
       FIG. 3  is a diagram illustrating an example of arrival information displayed on a display of an arrival information providing display device according to an example embodiment. 
     An arrival information providing display device may be a display board indicating an expected airplane arrival time for each flight number. The arrival information providing display device may be installed inside or outside an airport, but not limited thereto. 
     Referring to  FIG. 3 , the arrival information providing display device may receive, in real time, information from an arrival information providing server and display the received information. A portion of the information displayed by the arrival information providing display device may be information received from another server. 
     The arrival information providing display device may receive, from the arrival information providing server, information about an actual airplane arrival time at which an airplane arrives at an apron of an airport, and display the information about the actual airplane arrival time as a changed time, or a new time  310 . 
     The arrival information providing server may compare the expected airplane arrival time on schedule and the actual airplane arrival time and transmit, to the arrival information providing display device, information as to whether the airplane arrives or is delayed. The arrival information providing display device may display, in a remarks field  320  for each flight number, the information as to whether the airplane arrives or is delayed as information obtained through the comparing. 
     In addition, the arrival information providing display device may display, in a passenger out field  330 , an expected time at which a passenger of the airplane actually comes out of an arrival exit gate of the airport, which is determined by the arrival information providing server. As necessary, the arrival information providing display device may display, in the passenger out field  330 , a time at which a first passenger of the airplane actually comes out of the arrival exit gate. 
       FIG. 4  is a diagram illustrating an example of a location image and arrival information displayed on a display of an arrival information providing display device according to an example embodiment. 
     According to an example embodiment, an arrival information providing display device may display divided information in each field. Here, a plurality of fields may be provided, but the number of the fields is not limited to a certain number. For example, the arrival information providing display device may simultaneously display an airplane location that is received from an air control server, an airplane location for each flight number that is received from a ground control server, and a passenger location based on sensor information of a sensor located on a passenger movement route from an apron of an airport at which an airplane is parked to an arrival exit gate of the airport. In addition, as necessary, the arrival information providing display device may simultaneously display an airplane location for each flight number, a passenger location for each flight number, an expected arrival time for each flight number, a changed time or a new time, and a passenger out time. Here, the new time may be an actual airplane arrival time at which an airplane arrives at an apron of an airport. The expected arrival time may be an arrival time for each flight number based on flight information of each airplane. In addition, the arrival information providing display device may also display, in separate fields for each flight number, a location of the airplane located in the air before landing, a location of the airplane located at the apron after landing, and a location of a passenger of the airplane after the airplane is parked. 
     As shown in  410 , the arrival information providing display device may display, for each flight number, the airplane location that is obtained from an arrival information providing server after being received from the air control server, along with an illustration including a map including an airport or an area of the airport. Here, the displayed image may be an image received by the arrival information providing display device from the arrival information providing server. As necessary, the arrival information providing display device may store, in a memory, the illustration including the map including the airport or the area of the airport. In addition, the arrival information providing display device may receive, in real time from the arrival information providing server, the airplane location that is obtained from the arrival information providing server after being received from the air control server, and display the received airplane location for each flight number. Here, based on a distance between the received airplane location and the airport, the arrival information providing display device may display airplane sizes differently for each flight number. For example, as illustrated, the arrival information providing display device displays a flight KL1123 airplane, which is closest to the airport, to be of a relatively larger size. Conversely, the arrival information providing display device displays a flight KE1123 airplane, which is farthest from the airport, to be of a relatively smaller size. In addition, as shown in  440 , the arrival information providing display device may change and display, in real time, an airplane location that matches a flight number corresponding to a passenger out time being displayed. 
     As shown in  420 , the arrival information providing display device may display the airplane location for each flight number that is obtained from the arrival information providing server after being received from the ground control server, along with an image or an illustration of a runway at the airport on which the airplane lands or moves and an apron of the airport at which the airplane is parked. Here, the displayed image may be an image received by the arrival information providing display device from the arrival information providing server. 
     As shown in  430 , the arrival information providing display device may display a passenger location based on sensor information received from a sensor located on a passenger movement route from an apron at which each of airplanes  431  and  432  is parked to an arrival exit gate of the airport. 
     For example, as illustrated, the arrival information providing display device displays a location of a passenger of the airplane  431  using a flight number KE1231 of the airplane  431 . In addition, the arrival information providing display device displays a location of the passenger of the airplane  431  at a carousel using the flight number KE1231. As necessary, the arrival information providing display device may display locations of passengers of the airplanes  431  and  432  using a plurality of flight numbers. For example, the arrival information providing display device displays a location of a passenger of the airplane  432  using a flight number OZ1506 of the airplane  432 . Here, the location of the passenger of the airplane  432  may be one point in at least one of the apron, an entry gate, a quarantine station, an immigration checkpoint, a carousel, a customs inspection station, or an escalator. 
     The arrival information providing display device may receive, in real time, an image including passenger location information from the arrival information providing server. In addition, the arrival information providing display device may display the passenger location information using an average speed based on a preset passenger movement route that is transmitted, in real time, from the arrival information providing server. As necessary, the arrival information providing display device may display a passenger location for each flight number based on a passenger location received, in real time, from the arrival information providing server. For example, in a case that a passenger location obtained, in real time, from the arrival information providing server, is closest to the arrival exit gate on the passenger movement route, the obtained passenger location may be displayed as the passenger location for each flight number. Also, in a case that a passenger location obtained, in real time, from the arrival information providing server, is farthest from the arrival exit gate on the passenger movement route, the obtained passenger location may be displayed as the passenger location for each flight number. 
     The arrival information providing display device may display time information associated with a time at which the passenger of the airplane arrives. In addition, as shown in  440 , the arrival information providing display device may display a passenger out time determined based on the sensor information received from the sensor located on the passenger movement route from the apron to the arrival exit gate. 
     As shown in  441 , the time information may change in real time, or be maintained the same for three to five seconds. The arrival information providing display device may display same information in real time for three to five seconds. However, examples are not limited thereto. 
     As necessary, the arrival information providing display device may display information that guides an airport user around the airport, and display an advertisement. In addition, the arrival information providing display device may receive such guidance information or advertisement information from the arrival information providing server, and display an airplane location image, a passenger location image, and the guidance information or the advertisement information based on a preset period and area. 
     For example, the arrival information providing display device may simultaneously display a first airplane location image illustrated in  410 , a second airplane location image illustrated in  420 , and a first passenger location image illustrated in  430 , at regular time intervals. 
     In addition, the arrival information providing display device may display the guidance information or the advertisement information in place of one or two images of the first airplane location image illustrated in  410 , the second airplane location image illustrated in  420 , and the first passenger location image illustrated in  430 . Here, the arrival information providing display device may sequentially change information displayed in each field and display the sequentially changing information in each field. 
     For example, the arrival information providing display device may display the advertisement information in place of the first airplane location image illustrated in  410  and the second airplane location image illustrated in  420 . In addition, in a next time interval, the arrival information providing display device may display the advertisement information in place of the second airplane location image illustrated in  420  and the first passenger location image illustrated in  430 . 
       FIG. 5  is a diagram illustrating an example of an airplane location image based on an apron of an airport according to an example embodiment. 
     In a case of an airplane  510  being parked at an apron of an airport connected to a boarding bridge, an actual arrival time of the airplane  510  may be a time at which the airplane  510  arrives at the apron connected to the boarding bridge. Here, passenger location information may correspond to one point on a passenger movement route from the boarding bridge to an arrival exit gate of the airport. 
     An arrival information providing server may determine an expected passenger arrival time using length information of the boarding bridge. 
     In a case of an airplane  520  being parked at a remote apron of the airport, an actual arrival time of the airplane  520  may be a time at which the airplane  520  arrives at the remote apron. In such a case, since a passenger of the airplane  520  needs to move to an airport terminal by an airport shuttle bus, passenger location information may correspond to one point on a passenger movement route from the remote apron to the arrival exit gate of the airport. 
     Here, the arrival information providing server may determine an expected passenger arrival time using distance information associated with a distance from the remote apron to the airport terminal. 
     In addition, the arrival information providing server may determine the expected passenger arrival time based on a number of passengers of the airplane  520  and an average passenger number of each airport shuttle bus. 
       FIG. 6  is a diagram illustrating an example of a passenger location image based on a passenger movement route according to an example embodiment. 
     Referring to  FIG. 6 , a passenger movement route  610  includes at least one of an apron, an entry gate, a quarantine station  620 , an immigration checkpoint  630 , a carousel  640 , a customs inspection station  650 , or an escalator. 
     An arrival information providing server may determine a location of a passenger of an airplane based on sensor information received from a sensor located on a passenger movement route from an apron of an airport at which the airplane is parked to an arrival exit gate of the airport. 
     The sensor information may be identification information using a bar code or a radio frequency identification (RFID) that is read from a boarding pass of the passenger of the airplane or an additionally given identification tag. The sensor information may be information that is recognized, in a contact or noncontact method, from the boarding pass or the identification tag by a recognizer installed in each place on the passenger movement route. In addition, the sensor information including a time recognized from the boarding pass or the identification tag by such an additional recognizer in contact or noncontact method may be transferred, in real time, to the arrival information providing server. The time transferred to the arrival information providing server may be used for the arrival information providing server to calculate an accurate passenger out time. 
     In addition, referring to  FIG. 6 , a movement line is formed in order of the entry gate, the quarantine station  620 , the immigration checkpoint  630 , the carousel  640 , and the customs inspection station  650  based on a location of the apron. 
     The arrival information providing server may calculate an average passenger movement time using passenger image information obtained by capturing an image using an image capturer on a passenger movement route from the quarantine station  620  to the immigration checkpoint  630  and image-capturing time information associated with a time at which the image is captured. 
     For example, for a period of time from a time at which a first airplane among 20 airplanes arrives at an apron of an airport to a time at which a last airplane among the 20 airplanes arrives at the apron, information obtained by capturing images using an image capturer at the quarantine station  620  and an image capturer at the immigration checkpoint  630  may be used. In addition, in a case that image capturers capture approximately 40,000 passengers, the arrival information providing server may calculate an average movement time of the passengers using image information of each of the passengers and image-capturing time information of each of the passengers. For example, when the average movement time used for the passengers to move from the quarantine station  620  to the immigration checkpoint  630  is 43 seconds, the arrival information providing server may determine, to be 43 seconds, a passenger movement time to be used for the passengers to move along the passenger movement route from the quarantine station  620  to the immigration checkpoint  630  of a passenger location image. 
     In addition, the arrival information providing server may provide the arrival information providing display device with a passenger location on the passenger movement route based on the calculated average movement time of the passengers. Further, the arrival information providing server may generate, as an image, the passenger location on the passenger movement route and provide the generated image to the arrival information providing display device. 
       FIG. 7  is a diagram illustrating an entire arrival information providing system including an arrival information providing server according to an example embodiment.

As necessary, the passenger location image may be provided using a time calculated in real time corresponding to the route from the apron to the arrival exit gate. For example, the arrival information providing server  740  may obtain a first sensing time at which a passenger of a flight A or a passport of the passenger of the flight A is sensed by a first sensor, and a second sensing time at which the passenger of the flight A or the passport of the passenger of the flight A is sensed by a second sensor. Here, the arrival information providing server  740  may calculate, in real time, a movement speed of the passenger in a section from the first sensor to the section sensor using a distance between the first sensor and the second sensor on a preset route and a difference between the first sensing time and the second sensing time. As necessary, the arrival information providing server  740  may calculate movement speeds of passengers and calculate, in real time, an average movement speed of the passengers. In addition, the arrival information providing server  740  may determine a location of the passenger based on the average movement speed, and provide the determined location of the passenger as an image.

     The airplane arrival time determiner  910  may receive airplane information from an airplane information managing server of an airport at which an airplane is to arrive, and determine an actual airplane arrival time at which the airplane arrives at an apron of the airport. The airplane information managing server may be at least one of a flight information server, an air control server, or a ground control server. The airplane information managing server may manage, for example, an airplane flight number, airplane location information, and information about an expected location of an airplane at which the airplane is to land and to be parked. 
     The flight information server may be connected to the database configured to collect airplane flight information, and used to manage daily flight information of each airplane. In addition, the flight information server may interwork with airport facilities to control airport equipment. 
     The air control server may be connected to an air traffic control radar to transmit and receive the airplane information. The air control server may support a safe flight or navigation of an airplane both in the air and on the ground. In addition, the air control server may maintain desirable air traffic, and support an airfield control task, an access control task, and an airway control task based on a task range and a characteristic for each flight step. 
     The ground control server may be connected to a ground traffic control radar to transmit and receive the airplane information. The ground control server may be an integrated ground control system configured to detect, guide, and control airplanes and various support vehicles that move on a runway and a taxiway of an airport using radars and light controllers that are installed at the airport, and may support a safe flight and navigation of the airplanes. 
     The airplane information may include a location-based sensing time for each flight number that is received from sensors and radars at the airport managed by the airplane information managing server. As necessary, the airplane information may include a flight number, a current speed, an altitude, a schedule, and cycle information of the airplane, and an apron allocation time for the airplane, which is obtained by or stored in the airplane information managing server. The airplane arrival time determiner  910  may determine the actual airplane arrival time at which the airplane arrives at the apron of the airport using a landing time at which the airplane lands on a runway of the airport and a time used for the airplane to move from the runway to the apron. 
     The time used for the airplane to move from the runway to the apron may be determined based on at least one of an apron allocation time for the airplane or an estimated airplane movement time used for the airplane to move from the runway to the apron. 
     The passenger arrival time determiner  920  may calculate a passenger movement time from the actual airplane arrival time to a time at which a passenger of the airplane arrives at an arrival exit gate of the airport. In addition, the passenger arrival time determiner  920  may determine an expected passenger arrival time based on the actual airplane arrival time and the passenger movement time. 
     The passenger arrival time determiner  920  may determine the expected passenger arrival time based on sensor information received from a sensor located on a passenger movement route from the apron at which the airplane is parked to the arrival exit gate of the airport. 
     The sensor information may include passenger image information that is obtained by capturing an image using an image capturer located on the passenger movement route. In addition, the sensor information may include passenger identification information obtained by reading a passport, an identification card, a boarding pass, and an identification tag of the passenger.

     In a case that the apron at which the airplane is parked is connected to a boarding bridge, the passenger arrival time determiner  920  may determine the expected passenger arrival time based on length information of the boarding bridge. In addition, in a case that the apron at which the airplane is parked is a remote area, the passenger arrival time determiner  920  may determine the expected passenger arrival time based on distance information associated with a distance from the remote area to an airport terminal. 
     In addition, the passenger arrival time determiner  920  may determine the expected passenger arrival time from a current point in time based on a previously calculated expected passenger arrival time used for the passenger to move from the apron to the arrival exit gate. In a case that failure occurrence information is received from a sensor at the airport, the passenger arrival time determiner  920  may determine the expected passenger arrival time using a previously calculated average passenger movement time used for passengers to move from an apron identical to the apron at which the airplane is parked to an arrival exit gate identical to the arrival exit gate of the airport. 
     The arrival time transmitter  930  may transmit, to an arrival information providing display device, the actual airplane arrival time at which the airplane arrives at the apron and the expected passenger arrival time.
