Abstract

Method for automatically docking a passenger bridge (1, 2) to an airplane (5) door (3, 4) at an airport gate, wherein the airplane is brought to and stopped in a predetermined position by contact less measurement of the distance between the airplane and a fixed point and wherein a control computer (14) is adopted to control the movement of the passenger bridge and wherein a start signal (24) is required from a person after the person has established the correct type of airplane and version of the airplane type to enable the control computer to cause the passenger bridge to be moved for docking.

Claims

1. A method of automatically docking a passenger bridge or a goods handling bridge to a door of an airplane at an airport gate, comprising:

bringing the airplane (5) to a pre-determined position and stopped in said position by contactless measuring of a distance between the airplane and a fixed point;

indicating the distance on a display (6) mounted in front of a pilot of the airplane or on an airport structure (26);

causing the display (6) to show to the pilot the position of the airplane (5) relative to the airplane pre-determined position, and to show a type and a version of the type of airplane concerned;

activating said distance measuring and display functions by an airport installed data system (17); and

controlling movements of the passenger bridge with a control computer (14),

wherein subsequent to activation of a distance meter (13) for measuring said distance and of the display (6) for positioning an arriving airplane there is received from a person, a start signal (24),

said start signal received subsequent to having established that the correct type of airplane and the correct version of the airplane type has been set to enable the control computer (14) to cause the passenger bridge (1;

2) to be moved for docking with the airplane (5), provided that the airplane has stopped within a given pre-determined position interval, and

the distance meter (13) sends a signal to said control computer (14), which has access to data relating to the positions of the airplane doors on different airplane types and versions of airplane types, to guide movement of the passenger bridge (1;

2) to a position in which the cabin (15;

16) of the passenger bridge connects with the door (3;

4) of the airplane (5) in the absence of the influence of a driver.

2. The method according to claim 1, wherein said start signal (24) is sent from a control unit (25) received from a person who superintends the various airport gates, subsequent to the person having received an all-clear signal regarding the type of airplane concerned and the version of airplane type.

3. The method according to claim 2, wherein the start signal (21) sent by the pilot with the aid of a transmitter (22).

4. The method according to claim 2, wherein the display (6) shows the version of the type of airplane in addition to the airplane type to the pilot subsequent to activation of the distance meter (13) for measuring said distance and the display (6) for positioning of an incoming airplane, and in that when the pilot accepts the displayed type of airplane and the version of said airplane type, the pilot causes the airplane to move forwards to the pre-determined position, wherein movement of the airplane to said pre-determined position constitutes said start signal (24).

5. The method according to claim 1, wherein the start signal (21) is sent by the pilot with the aid of a transmitter (22).

6. The method according to claim 5, wherein the transmitter (22) is adapted to send one of radio waves and infrared light to a receiver (23) located in connection with one of the passenger bridge (1;

2) and said display (6).

7. The method according to claim 6, wherein the display (6) shows the version of the type of airplane in addition to the airplane type to the pilot subsequent to activation of the distance meter (13) for measuring said distance and the display (6) for positioning of an incoming airplane, and in that when the pilot accepts the displayed type of airplane and the version of said airplane type, the pilot causes the airplane to move forwards to the pre-determined position, wherein movement of the airplane to said pre-determined position constitutes said start signal (24).

8. The method according to claim 5, wherein the display (6) shows the version of the type of airplane in addition to the airplane type to the pilot subsequent to activation of the distance meter (13) for measuring said distance and the display (6) for positioning of an incoming airplane, and in that when the pilot accepts the displayed type of airplane and the version of said airplane type, the pilot causes the airplane to move forwards to the pre-determined position, wherein movement of the airplane to said pre-determined position constitutes said start signal (24).

9. The method according to claim 1, wherein the display (6) shows the version of the type of airplane in addition to the airplane type to the pilot subsequent to activation of the distance meter (13) for measuring said distance and the display (6) for positioning of an incoming airplane, and when the pilot accepts the displayed type of airplane and the version of said airplane type, the pilot causes the airplane to move forwards to the pre-determined position, wherein movement of the airplane to said pre-determined position constitutes said start signal (24).

10. The method according to claim 9, wherein information relating to an expected airplane type and version of said airplane type for activating said distance meter (13) and said display is taken from said data system (17).

11. The method according to claim 10, wherein information relating to an incoming airplane type and version of said airplane type for activating the distance meter (13) and the display (6) is read from a transponder (19) located in or on the airplane, with the aid of a reader (20) placed in connection with the display (6).

12. The method according to claim 9, wherein information relating to an incoming airplane type and version of said airplane type for activating the distance meter (13) and the display (6) is read from a transponder (19) located in one of in the airplane and on the airplane, with the aid of a reader (20) placed in connection with the display (6).

13. The method according to claim 1, wherein the distance meter (13) includes a device for sending and receiving electromagnetic pulses comprising one of a scanning laser (2) and a microwave system directed towards an area along a centre line (19) along which an airplane (5) is intended to move in an airplane positioning process and located in a position in front of a positioned airplane.

14. The method according to claim 1, wherein upon determining that one of type of airplane and version of the airplane type are incorrect, stopping the airplane at its current location.
