Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a boarding bridge control device and a boarding bridge including the same.
[0002]
[Prior art]
  Conventionally, a boarding bridge is known as a boarding / alighting device for an aircraft. A boarding bridge is a tunnel-like passage that can be extended and retracted and installed in an airport terminal building. When getting on and off, the cab at the tip of the boarding bridge is attached to an aircraft door, and passengers pass through the internal passage. To get on and off the aircraft.
[0003]
  Here, a limit switch is provided on the bumper at the tip of the cab of the boarding bridge. The limit switch is a switch configured to stop the traveling operation of the boarding bridge that is controlled and moved by an electric method when it comes into contact with the aircraft. Therefore, when the limit switch touches the aircraft, the boarding bridge that was moving stops and cannot move further.
[0004]
[Problems to be solved by the invention]
  However, since the limit switch is provided on the bumper, the bumper contacts the aircraft almost simultaneously with the contact of the limit switch with the aircraft. Therefore, if the operator does not operate the boarding bridge while always keeping the distance from the aircraft in mind, there is a risk of causing the boarding bridge to collide with the aircraft.
[0005]
  The present invention has been made in view of this point, and an object of the present invention is to provide a technique for safely mounting a boarding bridge to an aircraft.
[0006]
[Means for Solving the Problems]
  A boarding bridge control device according to the present invention detects a contact state between an aircraft and a cab that is provided at one end of a boarding bridge that connects an airport building and an alighting / alighting part of an aircraft and is detachably attached to the alighting / alighting part. Boarding comprising: one or more contact detection means; and a speed control means for controlling the speed of movement of the boarding bridge and stopping the boarding bridge when the contact state is detected by the contact detection means. A control device for a bridge, comprising: distance detection means for detecting a distance between the cab and the aircraft; and determination for determining whether or not the distance detected by the distance detection means is equal to or less than a preset set value. Means andIf the contact state is detected by the contact detection unit before the determination unit determines that the distance detected by the distance detection unit is equal to or less than the set value, the distance detection unit and the contact detection unit Warning means to notify that one or both of theThe speed control means decelerates the boarding bridge when it is determined by the determination means that the distance detected by the distance detection means is equal to or less than the set value.
[0007]
  Here, the contact state refers to a state where the cab and the aircraft are in contact with each other, or a state where the cab and the aircraft are close enough to be considered to be substantially in contact with each other.
[0008]
  According to the present invention, when the determination means determines that the distance between the cab and the aircraft detected by the distance detection means is equal to or less than a preset set value, the speed control means reduces the traveling speed. Therefore, since the traveling speed is automatically reduced before the boarding bridge is mounted on the aircraft, the possibility of the cab colliding with the aircraft is reduced. Therefore, the boarding bridge can be safely mounted on the aircraft even if it is not a skilled operator.
[0009]
  By the way, when the boarding bridge is moving at high speed, there is a higher possibility that the cab will collide with the aircraft than when the boarding bridge is moving at low speed.
[0010]
  Here, according to the present invention, even when the boarding bridge is moving at a high speed, the speed control means decelerates the traveling speed when the determination means determines that the distance is equal to or less than the set value. Thereby, even if the boarding bridge is moving at a high speed, the traveling speed is reduced before the boarding bridge is attached to the aircraft. Therefore, according to the present invention, when the boarding bridge is moving at a low speed, the boarding bridge can be safely attached to the aircraft even when the boarding bridge is moving at a high speed.
[0011]
  By the way, the set value is larger than the value of the distance between the cab and the aircraft when the cab and the aircraft are in contact with each other. Therefore, it is determined that the distance between the cab and the aircraft detected by the distance detecting unit is equal to or less than the set value by the determining unit than the contact detecting unit detects the contact state between the cab and the aircraft. It ’s the first thing. Therefore, if the contact state is detected by the contact detection unit before it is determined by the determination unit that the distance detected by the distance detection unit is equal to or less than the set value, the distance detection unit and the contact detection unit Either one or both may be out of order.
[0012]
  Here, according to the present invention, if the contact state is detected by the contact detection means before the distance detected by the distance detection means is determined to be less than or equal to the set value by the determination means, the warning means Informs that one or both of the distance detecting means and the contact detecting means is out of order. Therefore, according to the present invention, any of the distance detection means and the contact detection means It is possible to know that one or both of them has failed.
[0013]
  The present invention further includes a plurality of distance detection means, and the speed control means detects a distance detected by any one of the plurality of distance detection means below the set value by the determination means. When it is determined that the boarding bridge has been reached, the boarding bridge is decelerated.
[0014]
  By the way, the attitude of the cab can be changed with respect to the aircraft, and the fuselage of the aircraft is streamlined. Accordingly, the distance between the cab and the aircraft has different values depending on the installation position of the distance detecting means. Therefore, when the distance detecting means is singular, the distance detected by the distance detecting means may be different from the actual distance.
[0015]
  Here, according to the present invention, since the distance is detected by a plurality of distance detection means, the distance can be detected more accurately than in the case where the distance detection means is single. As a result, it is possible to reliably reduce the traveling speed before mounting the boarding bridge on the aircraft. Therefore, according to the present invention, the boarding bridge can be more safely attached to the aircraft.
[0016]
  A boarding bridge according to the present invention includes any one of the above-described boarding bridge controllers.
[0017]
【The invention's effect】
  According to the present invention, when the determination unit determines that the distance detected by the distance detection unit is equal to or less than a preset set value, the speed control unit automatically reduces the traveling speed. Accordingly, since the traveling speed is reduced before the boarding bridge is mounted on the aircraft, the boarding bridge can be safely mounted on the aircraft.
[0018]

[0023]
  The frame 21 is provided with a first detection unit 25 and a second detection unit 27.
[0024]
  As shown in FIGS. 4, 5, and 6, the first detection unit 25 is connected to the first distance detection distance sensor 29 that detects the distance between the communication unit 9 b of the cab 9 and the aircraft 13, and the cab 9.

The first distance detection distance sensor 29 and the first contact detection distance sensor 31 are infrared sensors. The first distance detection distance sensor 29 can also serve as a contact detection distance sensor. From the viewpoint of the function of the distance sensor, the first distance detection distance sensor 29 and the first contact detection distance sensor 29 can be used. It is preferable to provide the distance sensor 31 separately.
[0025]
  The second detection unit 27 has substantially the same configuration as the first detection unit 25. That is, the second detection unit 27 is provided with an infrared second distance detection distance sensor and a second contact detection distance sensor. The contact detection means is constituted by a first contact detection distance sensor 31 and a second contact detection distance sensor, and the distance detection means is constituted by a first distance detection distance sensor 29 and a second distance detection distance sensor. Yes.
[0026]
  An operation panel 37 as shown in FIG. 7 is provided inside the cab 9. The operation panel 37 includes an operation lever 39 for operating the driving wheel 17, an operation lever 39 for monitoring the driving wheel 17 and its surroundings, in addition to an operation switch for operating the lifting and lowering of the tunnel portion 7 and the rotation of the cab 9. One of the touch panel graphic display 41 with a monitor TV, the first distance detection distance sensor 29, the second distance detection distance sensor, the first contact detection distance sensor 31, and the second contact detection distance sensor has failed. A warning lamp 43 that blinks occasionally is provided. One of the first distance detection distance sensor 29, the second distance detection distance sensor, the first contact detection distance sensor 31, and the second contact detection distance sensor fails in the touch panel graphic display 41 with a monitor TV. Error message is displayed. The warning means includes a touch panel graphic display 41 with a monitor TV and a warning lamp 43.
[0027]
  The operation lever 39 is formed by a lever-like input device (joystick) having multi-directional degrees of freedom, and is configured to be tiltable in an arbitrary direction. When the operator pushes down the operation lever 39, the drive wheel 17 is It rotates until its direction matches the tilting direction of the operation lever 39, and then travels straight in that direction. A potentiometer, which will be described later, is connected to the operation lever 39, and analog data relating to the tilt direction and the tilt depth of the lever is digitized and processed by A / D conversion.
[0028]
  As shown in FIG. 8, the operation command transmission unit 45 that transmits the operation of the operation lever 39 to the drive wheel 17 includes a potentiometer 47 that detects the tilt direction angle and the tilt depth of the operation lever 39, and the actual operation of the operation lever 39. Calculating unit 49 for calculating a tilt direction angle (the tilt direction angle is synchronized with the traveling direction angle), a first distance detecting distance sensor 29, a second distance detecting distance sensor, and a first contact detecting distance sensor 31; Based on the detection result of the second contact detection distance sensor, a determination unit 51 that determines whether or not the distance between the communication unit 9b of the cab 9 and the aircraft 13 has reached a preset setting value; And a drive unit 53 that drives running and rotation. The drive unit 53 controls the speed of movement of the boarding bridge 1, that is, the cab 9, and when one of the first contact detection distance sensor 31 and the second contact detection distance sensor described later becomes Yes. The boarding bridge 1, that is, the cab 9 is stopped. Note that the determination unit is configured by the determination unit 51, and the speed control unit is configured by the drive unit 53.
[0029]
  The calculation unit 49 calculates the tilt direction angle of the operation lever 39 with respect to the operation panel 37 based on the signal from the potentiometer 47 and calculates the target rotation angle of the drive wheel 17. The drive unit 53 rotates the drive wheel 17 so that the rotation angle of the drive wheel 17 becomes the target rotation angle. And the drive part 53 will stop rotation, if the said rotation angle and the said target rotation angle become equal, and drive the driving wheel 17 after that. In the present embodiment, the traveling speed of the drive wheel 17 is set so that the normal rotation speed of the drive wheel 17 is 20 Hz. Here, as a matter of course, the traveling speed may be changed according to the tilting depth of the operating lever 39 so that the traveling speed becomes faster as the tilting depth of the operating lever 39 is deeper.
[0030]
  Based on the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor, the determination unit 51 reduces the distance between the communication unit 9b of the cab 9 and the aircraft 13 to a preset value or less. It is determined whether or not. Here, the set value can be changed, and in the present embodiment, the set value is set to 0.5 m in advance. When both of the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor are No, the drive unit 53 keeps the rotational speed of the drive wheels 17 at 20 Hz. On the other hand, when any one of the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor becomes Yes, the drive unit 53 reduces the rotation speed of the drive wheel 17 from 20 Hz. In this embodiment, the drive part 53 reduces the rotation speed of the drive wheel 17 to 6 Hz.
[0031]
  Further, the determination unit 51 sets the distance between the communication unit 9b of the cab 9 and the aircraft 13 to a preset value based on the detection results of the first contact detection distance sensor 31 and the second contact detection distance sensor. It is determined whether or not. Here, it is preferable that the set value is substantially 0. In the present embodiment, the set value is set to 0.1 m in advance. When both the determination results of the first contact detection distance sensor 31 and the second contact detection distance sensor are No, the drive unit 53 maintains the rotational speed of the drive wheel 17 as it is. On the other hand, when one of the first contact detection distance sensor 31 and the second contact detection distance sensor becomes Yes, the drive unit 53 reduces the rotation speed of the drive wheel 17 to 0 Hz.
[0032]
  Here, the process of attaching the cab 9 of the boarding bridge 1 to the door 13a of the aircraft 13 using the boarding bridge control apparatus according to the present embodiment will be described. Here, it is assumed that the boarding bridge 1 is in a standby position (solid boarding bridge) as shown in FIG.
[0033]
  First, an operator who has boarded the cab 9 visually grasps the position of the door 13a of the aircraft 13 when moving from the standby position of the boarding bridge 1 to the mounting position (a two-dot chain line boarding bridge), and then performs an operation. The lever 39 is pushed down in the direction of the door 13a. By operating the operation lever 39, the driving wheel 17 rotates on the spot until the traveling direction thereof matches the tilting direction of the operation lever 39. Thereafter, the drive wheel 17 travels straight toward the tilt direction at a rotation speed of 20 Hz. At this time, the heights of the tunnel portion 7 and the cab 9 are appropriately adjusted by the operator according to the position of the door 13 a of the aircraft 13.
[0034]
  Here, when the drive wheel 17 is linearly moved to the mounting position, the determination unit 51 determines whether or not the communication unit 9b of the cab 9 is based on the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor. It is determined whether the distance between the aircraft 13 and the aircraft 13 has become 0.5 m or less. At the same time, based on the detection results of the first contact detection distance sensor 31 and the second contact detection distance sensor, the determination unit 51 determines whether the distance between the communication unit 9b of the cab 9 and the aircraft 13 is 0.1 m. Judging. When the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor and the first contact detection distance sensor 31 and the second contact detection distance sensor are all No, the drive unit 53 keeps the rotation speed of the drive wheel 17 at 20 Hz.
[0035]
  Next, when the drive shaft 17 moves linearly toward the mounting position, one or both of the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor become Yes. Sometimes, the drive unit 53 reduces the rotational speed of the drive wheel 17 from 20 Hz to 6 Hz. When one of the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor becomes Yes, the detection result of the other distance detection distance sensor is also one of the distance detection distance sensors. It is Yes slightly after the distance sensor.
[0036]
  Next, when the driving wheel 17 is further linearly moved toward the mounting position, one or both of the detection results of the first contact detection distance sensor 31 and the second contact detection distance sensor become Yes. When this occurs, the drive unit 53 reduces the rotational speed of the drive wheel 17 from 6 Hz to 0 Hz. When one of the detection results of the first contact detection distance sensor 31 and the second contact detection distance sensor becomes Yes, the detection result of the other contact detection distance sensor is also detected by one of the contacts. It is Yes with a slight delay from the working distance sensor. Thereby, the linear movement of the drive wheel 17 is completed, and the boarding bridge 1 reaches the mounting position as shown in FIG. Thus, the mounting of the boarding bridge 1 to the aircraft 13 is completed.
[0037]
  According to the present embodiment, when one or both of the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor become Yes, the drive unit 53 rotates the rotational speed of the drive wheel 17. Is reduced from 20 Hz to 6 Hz. Therefore, before the boarding bridge 1 is mounted on the aircraft 13, the rotational speed of the drive wheels 17 is reduced to 6 Hz, so that the possibility that the boarding bridge 1 collides with the aircraft 13 is reduced. Therefore, the boarding bridge 1 can be safely attached to the aircraft 13.
[0038]
  Further, when one or both of the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor become Yes, the drive unit 53 reduces the rotation speed of the drive wheel 17 to 6 Hz. . Thereby, whatever the value of the rotation speed of the drive wheel 17, the drive part 53 reduces the rotation speed of the drive wheel 17 to 6 Hz. Therefore, the boarding bridge 1 can be safely mounted on the aircraft 13 no matter what the rotational speed of the drive wheels 17 is.
[0039]
  Since the set value can be changed from 0.5 m, the boarding bridge control device according to the present embodiment can be used for mounting various boarding bridges 1 on the aircraft 13.
[0040]
  By the way, the cab 9 is configured to be movable up and down and to be rotatable forward and backward about the vertical axis with respect to the second tunnel 7b, and the fuselage of the aircraft 13 is streamlined. Therefore, the distance between the communication portion 9b of the cab 9 and the aircraft 13 has different values depending on the installation position of the distance detection sensor on the frame 21. Therefore, when there is a single distance detection sensor, the distance detected by the distance detection sensor may be different from the actual distance.
[0041]
  Here, according to the present embodiment, since the distance between the communication portion 9b of the cab 9 and the aircraft 13 is detected by the first distance detection distance sensor 29 and the second distance detection distance sensor, the distance detection distance sensor. The distance can be accurately detected as compared with the case where the number is. Therefore, it is possible to reliably reduce the rotational speed of the drive wheels 17 by the drive unit 53 before the boarding bridge 1 is attached to the aircraft 13. Therefore, the boarding bridge 1 can be mounted on the aircraft 13 more safely.
[0042]
  (Embodiment 2)
  The boarding bridge 1 according to the present embodiment has substantially the same configuration as the boarding bridge 1 of the first embodiment.
[0043]

Here, it is assumed that the boarding bridge 1 is in a standby position (solid boarding bridge) as shown in FIG.
[0044]
  First, the operator who gets into the cab 9 pushes down the operation lever 39 in the direction of the door 13a. By operating the operation lever 39, the driving wheel 17 rotates on the spot until the traveling direction thereof matches the tilting direction of the operation lever 39. Thereafter, the drive wheel 17 travels straight toward the tilt direction at a rotation speed of 20 Hz.
[0045]
  Next, when the drive wheel 17 is moving linearly toward the mounting position, the first distance detection distance sensor 29 and the second distance detection distance sensor are both No. When one or both of the first contact detection distance sensor 31 and the second contact detection distance sensor becomes Yes, the warning lamp 43 of the operation panel 37 blinks and at the same time, the touch panel graphic display 41 with the monitor TV is displayed. Error message is displayed.
[0046]
  According to the present embodiment, the warning lamp 43 of the operation panel 37 blinks and an error message is displayed on the touch panel graphic display 41 with a monitor TV, so that the operator can detect the first distance detection distance sensor. 29, it can be known that any one of the second distance detection distance sensor, the first contact detection distance sensor 31, and the second contact detection distance sensor has failed.
[0047]
  (Embodiment 3)

[0048]
  Here, the process of attaching the cab 9 of the boarding bridge 1 to the door 13a of the aircraft 13 using the boarding bridge control apparatus according to the present embodiment will be described. Here, it is assumed that the boarding bridge 1 is in a standby position (solid boarding bridge) as shown in FIG.
[0049]
  First, the operator who gets into the cab 9 pushes down the operation lever 39 in the direction of the door 13a. By operating the operation lever 39, the driving wheel 17 rotates on the spot until the traveling direction thereof matches the tilting direction of the operation lever 39. Thereafter, the drive wheel 17 travels straight toward the tilt direction at a rotation speed of 20 Hz.
[0050]
  Next, when the detection result of the first distance detection distance sensor 29 is Yes when the drive wheel 17 is linearly moving toward the mounting position, the drive unit 53 determines the rotation speed of the drive wheel 17. Decrease from 20 Hz to 6 Hz.
[0051]
  Next, when the drive wheel 17 further moves linearly toward the mounting position and one or both of the first contact detection distance sensor 31 and the second contact detection distance sensor become Yes, the drive unit 53. Decreases the rotational speed of the drive wheel 17 from 6 Hz to 0 Hz. When one of the detection results of the first contact detection distance sensor 31 and the second contact detection distance sensor becomes Yes, the detection result of the other contact detection distance sensor is also used for one of the contact detections. It is Yes slightly after the distance sensor. Thereby, the linear movement of the drive wheel 17 is completed, and the boarding bridge 1 reaches the mounting position as shown in FIG. Thus, the mounting of the boarding bridge 1 to the aircraft 13 is completed. At this time, if the detection result of the second distance detection distance sensor is still No, the warning lamp 43 blinks.
[0052]
  According to the present embodiment, the warning lamp 43 of the operation panel 37 blinks, so that the operator can know that the second distance detection distance sensor has failed.
[0053]
