Method for automated handling a passenger boarding bridge
The invention refers to a method for automated handling a passenger boarding bridge.
Nowadays the docking of the passenger boarding bridge (PBB) to an aircraft is performed manually. An operator is using a joystick, giving immediate operation signals to the drive means. This kind of docking is time consuming and requires an operator. In case the operator is still busy at another PBB, the docking is delayed, which leads to costly delays in ground handling of aircrafts. Consequently, the market requires a possibility of automatic docking, in which no fully trained and certified operator is needed through the complete docking procedure anymore.
A camera based automatic docking is disclosed in WO 2017/198605 Al . To detect a door contour, a line of windows is detected. A door contour is searched at a position adjacent to the line of windows. Based on the detected door an automatic movement of the PBB is initiated, to get the PBB in alignment with the door of the aircraft.
German patent application 10 2018 211 492.7 discloses a method for automated docking a passenger boarding bridge to an aircraft.
German patent application 10 2018 215 519.4 discloses a method for detecting the aircraft door status, i.e. whether the door is closed or not closed.
German patent application 10 2018 212 530.9 discloses a method for automated undocking a passenger boarding bridge from an aircraft.
The term automated handling is to be understood as generic term covering terms automated docking and automated undocking.
It is the object to improve the procedures in connection with the automated handling of a passenger boarding bridge. The object of the invention is solved by a method according to the main claims; embodiments are disclosed in the subclaims and the description.
Within the scope of the application an operator is meant to be a person located at the airport and operating or supervising the function of the passenger boarding bridge. The operator is not a member of the aircraft crew.
The invention is explained in more detail by means of the figure, the figures show: fig. 1 a top view on an aircraft and a passenger boarding bridge;
fig. 2 sections through the aircraft and the passenger boarding bridge during the inventive method;
fig. 3 frontal views on the passenger boarding bridge during the inventive method;
fig. 4 top views into the bridgehead of the during the inventive method;
fig. 5 a structure diagram of the main components of the passenger boarding bridge fig. 6 a perspective view on a floor system of the passenger boarding bridge.
Figure 1 shows a passenger boarding bridge 10 which is to be docked to or undocked from an aircraft 1 in an automated docking procedure (e.g. disclosed in PCT/EPPCT/EP2019/063906) or undocking procedure (e.g. disclosed in patent application PCT/EP2019/066963). The passenger boarding bridge 1 has a tunnel 11 which can be telescoped. During docking a bridgehead 13 is to be aligned with an aircraft door 3 of the aircraft 1. A drive system 12 is provided for moving the passenger boarding bridge, i.e. for changing the position of the bridgehead 13. For more background information reference is made to the aforementioned applications, the content of which is incorporated herein by reference.
The bridgehead 13 can be moved by means of the drive means 12 into a docking position which is shown in figures 2a and 2b. Here an approaching edge 44 of a floor bumper 43 is aligned to the fuselage 2 in a manner, that passengers can safely step over from a floor 41 of the bridgehead 13 through the open aircraft door 3 into the aircraft 1. In the docking position the approaching edge 44 may contact the fuselage 2 or there may be a small gap between the approaching edge and the fuselage. A PBB position signal A20 indicating that the PBB 10 is in the docking position (figures 2a, 2b) or alternatively in a retracted position (not shown).
The bridgehead 13 is equipped with a canopy 50, having a canopy roof 53, a canopy bumper 51 and a canopy drive 52. The canopy drive 52 is adapted to move the canopy roof 53 and the bumper 51 between a contact position (figure 2b) and a retracted position (figure 2a). In the contact position the bumper 51 overlaps, in some embodiments contacts, the aircraft fuselage 2 so that passengers are protected from rain; in the retracted position, bumper 51 is distant to the aircraft fuselage 2 (figure 2a). During docking the canopy 50 may still be in the retracted position when the bridgehead already has reached it’s docking position. As soon as the movement of the bridgehead 13 is finished a movement of the canopy 50 into the contact position can be started. A canopy sensor 54 can detect any contact between the bumper 51 and the fuselage 2 for providing a canopy status signal A50. Figure 3 shows the bridgehead in front view. A bridgehead interior 14 is defined by the bridgehead floor 41, side walls 23 and a cabin roof 19. A shutter 60 is provided to close a passage for passengers between the tunnel 11 and the bridgehead 13 for safety reasons. The shutter 60 can be closed (figure 3a) or opened (figure 3b). A shutter status signal A60 is provided by the shutter 60 indicating the closed or open status. The shutter 60 can be a rolling shutter as illustrated in figure 3 or usual door provided with a horizontal opening / closing mechanism.
Within the bridgehead there is provided a signaling device 90, in this particular embodiment a signaling lamp 90. The signaling device 90 is adapted to provide a door opening allowance to the aircraft crew. This can be a provided in the form of an, in particular visual, indication, whether the crew is allowed to open the aircraft door or not. A crew member can identify the status of the signaling device in particular through a window in the fuselage. If the signaling device indicates allowance for door opening (in particular a green light as shown in figure 3b), the crew may open the door. As long as the signaling device indicates, that the door must not be opened (in particular a red light as shown in figure 3a) the crew is not allowed to open the door. During undocking the signaling device can switch from door opening allowance status to door opening not allowance status. Then crew has to close the door.
Figure 4 shows the functionality of a leveling system 80, in particular a safety leveling system from a top view perspective on to the floor 41 of the bridgehead 13. Here the leveling system 80 comprises a safety shoe 81, which can be placed between the aircraft door 3 and the floor 41 of the bridgehead 13. The safety shoe 81 is a sensors detecting unintended lowering of the aircraft door 3 relative to the floor 41. In figure 4a the PBB 10 is still in a retracted position. The leveling system 80 is in an inactive state. In figure 4b the PBB 10 is in the docking position, since fuselage 3 is contacting (small gap possible) the approaching edge 44 of the bridgehead 13. The leveling system is still inactive in figure 4b. In particular the safety shoe 81 is still outside of a swivel area of the door 3, when the PBB 10 is in docking position.
After the aircraft door 3 is opened (figure 4c) the leveling system 80 is activated, in particular by employing a positioning actuator 82. In particular the safety shoe 81 is put between the aircraft door 3 and the bridgehead floor 41 (figure 4d). KR 2013 0050565 A discloses a system for positioning a safety shoe.
In figures 4a and 4b the aircraft door 3 is closed. The door status can be detected by an aircraft door status detection system 70 in particular having a camera 71. An exemplary embodiment is described in patent application PCT/EP2019/071307. The door status detection system 70 issues an aircraft door status signal A70, which can be either“closed” or“open”. Not before the aircraft door status signal A70 changes from“closed” to“open” the safety shoe 81 is placed under the opened aircraft door 3 as shown in figure 4d.
Figure 6 shows a floor system 40. The floor system comprises the floor 41 of the bridgehead 13 and the floor bumper 44 with the approaching edge 43. Figure 6 shows the floor system in a standby shape. Here the floor 41 is oriented parallel to the bridgehead 13 and the bumper 43 is retracted. The floor system 40 issues signal A40, that it is the a standby shape.
For providing a perfect alignment with the aircrafts fuselage (not shown) the shape of the floor system can be varied. In particular the angular orientation of the floor with respect to the bridgehead can be changed by means of a rotational actuator 42a. The curvature of the bumper 44 can be varied by means of bumper actuators. A respective example of a bumper, which curvature can be varied by actuators, is disclosed in EP 3 495 276 Al .
Sensors 42, 42b are provided to determine the shape of the floor system. The values provided by the sensors are used to issue the floor shape signal A40.
Figure 5 shows schematically the units of the boarding system. A central control unit 110 is provided for controlling the functions of devices of the PBB. The control unit 110 receives the following signals:
- the PBB position signal A20,
- the floor shape signal A40,
- the canopy status signal A50,
- the shutter status signal A60,
- the aircraft door status signal A70 and
- the leveling system status signal A80.
The control unit 110 provides the following instructions:

- an instruction C40 to the floor actuators 12 to change the shape of the floor system 40,
- an instruction C50 to change status of canopy,
- an instruction C60 to change the status of the shutter,
- an instruction C70 to check the door status,
- an instruction C80 to change the status of the leveling system.
When docking is finished, the control unit provides a’’ready for passengers entering the boarding bridge” signal R1 to an operator. The’’ready for passengers entering the boarding bridge” signal R1 is indicated via a human-machine-interface HMI, in particular via an optical or acoustical signal. The control unit 110 provides further a door opening allowance DOA, which is output by the signaling means 90 to the aircraft crew in particular in the form of a green light (see figure 3b).
When boarding is finished and the PBB is prepared so that the door can be closed the control unit provides a ready for door closing signal R2 to an operator. The ready for door closing signal R2 is indicated via a man machine interface HMI, in particular via an optical or acoustical signal. The control unit 110 further withdraws the door opening allowance DOA, which is output by the signaling means 90 to the aircraft crew, in particular in the form of a red light (see figure 3a).
