Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boarding bridge controller and a boarding bridge including the same.

[0002]

2. Description of the Related Art Conventionally, as a boarding / alighting device for aircraft,
The boarding bridge is known. A boarding bridge is a tunnel-like passage that is installed in an airport terminal building and can be expanded and contracted and rotated. To get on and off the aircraft.

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 which is controlled and moved by an electrical method when the aircraft touches the aircraft.
Therefore, if the limit switch touches the aircraft,
The boarding bridge that was in motion stops and cannot proceed any further.

[0004]

However, since the limit switch is provided on the bumper, almost simultaneously with the contact of the limit switch with the aircraft, the bumper also comes into contact 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.

The present invention has been made in view of the above points, and an object thereof is to provide a technique for safely mounting a boarding bridge on an aircraft.

[0006]

A control device for a boarding bridge according to the present invention is provided at one end of a boarding bridge connecting an airport building and a boarding / alighting section of an aircraft, and is detachably attached to the boarding / alighting section. One or more contact detection means for detecting the contact state between the aircraft and the aircraft, and the speed of movement of the boarding bridge are controlled, and the boarding bridge is activated when the contact state is detected by the contact detection means. A control device for a boarding bridge comprising speed control means for stopping the distance detection means for detecting the distance between the cab and the aircraft, and the distance detected by the distance detection means is set to a preset value or less. The speed control means detects the distance by the distance detection means. When distances is determined to equal to or less than the set value by said judging means is for decelerating the boarding bridge.

Here, the contact state means 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.

According to the present invention, the speed control means decelerates the traveling speed when the determination means determines that the distance between the cab and the aircraft detected by the distance detection means becomes equal to or less than a preset set value. . Therefore, since the traveling speed is automatically reduced before the boarding bridge is mounted on the aircraft, the cab is less likely to collide with the aircraft. Therefore, the boarding bridge can be safely attached to the aircraft even if not a skilled operator.

By the way, when the boarding bridge is moving at high speed, the cab is more likely to collide with the aircraft than when the boarding bridge is moving at low speed.

According to the present invention, even if the boarding bridge is moving at a high speed, the speed control means reduces the traveling speed when the determining means determines that the distance is equal to or less than the set value. . As a result, even if the boarding bridge is moving at high speed, the traveling speed is reduced before the boarding bridge is attached to the aircraft. Therefore, according to the present invention, it is possible to mount the boarding bridge on the aircraft safely even when the boarding bridge is moving at a low speed as well as when the boarding bridge is moving at a high speed.

The present invention further comprises a plurality of distance detecting means, wherein the speed control means is one of the plurality of distance detecting means.
The boarding bridge is decelerated when the distance detected by any one of the distance detecting means is determined to be equal to or less than the set value by the determining means.

By the way, the cab can change its attitude with respect to the aircraft, and the body of the aircraft has a streamlined shape. Therefore, the distance between the cab and the aircraft has different values depending on the installation position of the distance detecting means. Therefore, when the number of the distance detecting means is one, the distance detected by the distance detecting means may be different from the actual distance.

According to the present invention, since the distances are detected by the plurality of distance detecting means, the distance can be detected more accurately than in the case where the distance detecting means is single. As a result, the traveling speed can be surely reduced before the boarding bridge is mounted on the aircraft. Therefore, according to the present invention, the boarding bridge can be mounted on the aircraft more safely.

According to the present invention, further, when the contact state is detected by the contact detection means before the distance detected by the distance detection means is determined to be equal to or less than the set value by the determination means, the distance detection is performed. A warning means is provided to inform that one or both of the means and the contact detection means are out of order.

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 means is equal to or less than the set value by the determining means, than when the contact detecting means detects the contact state between the cab and the aircraft. That is the future. Therefore, if the contact state is detected by the contact detection unit before the distance detected by the distance detection unit is determined to be equal to or less than the set value by the determination unit, the distance detection unit and the contact detection unit are detected. Either one or both may be out of order.

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 equal to or less than 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 are out of order. Therefore, according to the present invention, it is possible to know that either one or both of the distance detecting unit and the contact detecting unit is out of order.

A boarding bridge according to the present invention comprises any one of the above-mentioned boarding bridge control devices.

[0018]

According to the present invention, the speed control means automatically reduces the traveling speed when the determination means determines that the distance detected by the distance detection means becomes less than or equal to a preset set value. . Therefore, 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.

Further, the first distance detecting distance sensor 29 can also serve as a contact detecting distance sensor, but from the functional viewpoint of the distance sensor, the first distance detecting distance sensor 29 and the first contact detecting distance sensor It is preferable to provide the distance sensor 31 separately.

The second detecting section 27 has substantially the same structure as the first detecting section 25. That is, the second detection unit 27 is provided with an infrared type second distance detecting distance sensor and a second contact detecting distance sensor. The contact detection means is composed of a first contact detection distance sensor 31 and a second contact detection distance sensor, and the distance detection means is composed of a first distance detection distance sensor 29 and a second distance detection distance sensor. There is.

An operation panel 37 as shown in FIG. 7 is provided inside the cab 9. On the operation panel 37,
In addition to the operation switches for operating the raising and lowering of the tunnel portion 7 and the rotation of the cab 9, an operation lever 39 for operating the drive wheels 17, and a touch panel graphic display with a monitor TV for monitoring the drive wheels 17 and the periphery thereof. Vessel 41,
A warning lamp 43 is provided which blinks when any one of the first distance detecting distance sensor 29, the second distance detecting distance sensor, the first contact detecting distance sensor 31, and the second contact detecting distance sensor fails. Has been. Any one of the first distance detecting distance sensor 29, the second distance detecting distance sensor, the first contact detecting distance sensor 31, and the second contact detecting distance sensor is malfunctioning in the touch panel graphic display 41 with monitor TV. Error message is displayed. The warning means is composed of a touch panel graphic display 41 with a monitor TV and a warning lamp 43.

The operating lever 39 is formed by a lever-shaped input device (joystick) having multiple degrees of freedom and is tiltable in any direction. When the operator pushes down the operating lever 39, the operating lever 39 is driven. The wheel 17 is rotated 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 tilting direction and the tilting depth of the lever are digitized by A / D conversion and processed.

As shown in FIG. 8, the operation command transmission portion 45 for transmitting the operation of the operation lever 39 to the drive wheels 17 includes a potentiometer 47 for detecting the tilt direction angle and the tilt depth of the operation lever 39, and an operation lever. A calculation unit 49 that calculates the actual tilt direction angle of 39 (the tilt direction angle is synchronized with the traveling direction angle), the first distance detection distance sensor 29, the second distance detection distance sensor, and the first contact detection distance. 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 set value based on the detection results of the sensor 31 and the second contact detection distance sensor; Drive unit 5 that drives the traveling and rotation of wheels 17.
3 and 3. The drive unit 53 controls the moving speed of the boarding bridge 1, that is, the cab 9, and also includes a first contact detection distance sensor 31 and a second contact detection distance sensor 31 described later.
When either one of the distance sensors for contact detection becomes Yes, the boarding bridge 1, that is, the cab 9
Is to stop. The determining means is the determining unit 51.
And the speed control means is constituted by the drive unit 53.

The calculation unit 49 calculates the angle of the tilt direction 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 unit 53 stops rotating when the rotation angle becomes equal to the target rotation angle, and then drives the drive wheels 17. In the present embodiment, the traveling speed of the drive wheels 17 is set so that the normal rotation speed of the drive wheels 17 is 20 Hz. Here, the operating lever 39 is set so that the traveling speed becomes faster as the tilting depth of the operating lever 39 becomes deeper.
Needless to say, the traveling speed may be changed according to the tilting depth.

The determination unit 51 sets a preset value for the distance between the communication unit 9b of the cab 9 and the aircraft 13 based on the detection results of the first distance detection distance sensor 29 and the second distance detection distance sensor. It is determined whether or not the following. 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 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 rotation speed of the drive wheels 17 at 20 Hz. On the other hand, when one of the detection results of the first distance detecting distance sensor 29 and the second distance detecting distance sensor is Yes, the drive unit 53 reduces the rotation speed of the drive wheel 17 from 20 Hz. In the present embodiment, the drive unit 53 reduces the rotation speed of the drive wheels 17 to 6 Hz.

Further, the determination section 51 presets the distance between the contact section 9b of the cab 9 and the aircraft 13 based on the detection results of the first contact detection distance sensor 31 and the second contact detection distance sensor. It is determined whether the set value has been reached. Here, it is preferable that the above-mentioned set value takes a value of almost 0,
In the present embodiment, the set value is set to 0.1 m in advance. Then, the first contact detection distance sensor 31
If both the determination results of the second contact detection distance sensor are No, the drive unit 53 keeps the rotation speed of the drive wheel 17 as it is. On the other hand, one of the first contact detection distance sensor 31 and the second contact detection distance sensor is Y.
When it becomes es, the drive unit 53 reduces the rotation speed of the drive wheels 17 to 0 Hz.

Now, a process of attaching the cab 9 of the boarding bridge 1 to the door 13a of the aircraft 13 by using the boarding bridge controller according to the present embodiment will be described. Here, it is assumed that the boarding bridge 1 is in the standby position (solid boarding bridge) as shown in FIG.

First, the operator who gets into 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 (boarding bridge of two-dot chain line), then,
The operation lever 39 is pushed down toward the door 13a. By operating the operation lever 39, the drive wheel 17 rotates on the spot until the traveling direction matches the tilting direction of the operation lever 39. After that, the drive wheels 17 travel straight in the tilting direction at a rotation speed of 20 Hz. At this time, the elevation heights of the tunnel portion 7 and the cab 9 are appropriately adjusted by the operator according to the position of the door 13a of the aircraft 13.

Here, when the drive wheel 17 is linearly moving to the mounting position, the determining unit 51 causes the cab 9 to move based on the detection results of the first distance detecting distance sensor 29 and the second distance detecting distance sensor. It is determined whether or not the distance between the contact portion 9b 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 contact portion 9b of the cab 9 and the aircraft 13 is 0.1 m. Is being determined. Then, the first distance detecting distance sensor 29, the second distance detecting distance sensor, and the first
If both the detection results of the contact detection distance sensor 31 and the second contact detection distance sensor are No, the drive unit 53
Keeps the rotational speed of the drive wheel 17 at 20 Hz.

Next, when the drive shaft 17 is linearly moving toward the mounting position, the first distance detecting distance sensor 29 is detected.
When either or both of the detection results of the second distance detection distance sensor are Yes, the drive unit 53 reduces the rotation speed of the drive wheel 17 from 20 Hz to 6 Hz. Note that when one of the detection results of the first distance detecting distance sensor 29 and the second distance detecting distance sensor is Yes, the detection result of the other distance detecting distance sensor is also one of the distance detecting distance sensors. Yes, a little later than the distance sensor.

Next, when the drive wheel 17 is further linearly moving toward the mounting position, one or both of the detection results of the first contact detecting distance sensor 31 and the second contact detecting distance sensor are detected. When the result is Yes, the drive unit 53 reduces the rotation speed of the drive wheels 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 is Yes, the detection result of the other contact detection distance sensor is also one of the contact detection results. Ye, slightly behind the working distance sensor
It has become s. As a result, the linear movement of the drive wheels 17 is completed, and the boarding bridge 1 reaches the mounting position as shown in FIG. From the above, the boarding bridge 1
The mounting on the aircraft 13 is completed.

According to this embodiment, when either or both of the detection results of the first distance detecting distance sensor 29 and the second distance detecting distance sensor become Yes, the drive unit 53 causes the drive wheel 17 to move. The rotation speed of is reduced from 20 Hz to 6 Hz. Therefore, the aircraft 13 of the boarding bridge 1
Since the number of rotations of the drive wheels 17 is reduced to 6 Hz before being mounted on the vehicle, the risk of the boarding bridge 1 colliding with the aircraft 13 is reduced. Therefore, the boarding bridge 1 can be safely attached to the aircraft 13.

When either or both of the detection results of the first distance detecting distance sensor 29 and the second distance detecting distance sensor are Yes, the drive unit 53 causes the drive wheel 1 to move.
The rotation speed of 7 is reduced to 6 Hz. As a result, the drive unit 53 reduces the rotation speed of the drive wheel 17 to 6 Hz regardless of the rotation speed of the drive wheel 17. Therefore,
No matter what value the rotational speed of the drive wheel 17 is,
The boarding bridge 1 can be safely attached to the aircraft 13.

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 a wide variety of boarding bridges 1 on the aircraft 13. .

By the way, the cab 9 is vertically movable and rotatable forward and backward about the vertical axis with respect to the second tunnel 7b, and the body of the aircraft 13 has a streamlined shape.
Therefore, the distance between the connecting 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 the number of sensors for distance detection is singular, the distance detected by the sensor for distance detection may be different from the actual distance.

According to this embodiment, the distance between the connecting portion 9b of the cab 9 and the aircraft 13 is detected by the first distance detecting distance sensor 29 and the second distance detecting distance sensor. The above distance can be detected more accurately than in the case where a single working distance sensor is used. Therefore, the reduction of the rotation speed of the drive wheels 17 by the drive unit 53
This can be surely performed before mounting the boarding bridge 1 on the aircraft 13. Therefore, the boarding bridge 1 can be mounted on the aircraft 13 more safely.

(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.

Now, a process of attaching the cab 9 of the boarding bridge 1 to the door 13a of the aircraft 13 by using the boarding bridge control device according to this embodiment will be described. Here, it is assumed that the boarding bridge 1 is in the standby position (solid boarding bridge) as shown in FIG.

First, the operator who gets into the cab 9 pushes down the operation lever 39 toward the door 13a. By operating the operation lever 39, the drive wheel 17 rotates on the spot until the traveling direction matches the tilting direction of the operation lever 39. After that, the drive wheels 17 travel straight in the tilting direction at a rotation speed of 20 Hz.

Next, when the drive wheel 17 is linearly moving toward the mounting position, the first distance detecting distance sensor 29 is detected.
Despite the detection results of both the second distance detection distance sensor and No, either or both of the first contact detection distance sensor 31 and the second contact detection distance sensor are Yes.
When s is reached, the warning lamp 43 of the operation panel 37 blinks and at the same time, an error message is displayed on the touch panel graphic display 41 with monitor TV.

According to this 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 monitor TV, so that the operator can detect the first distance. It is possible to know that any one of the working distance sensor 29, the second distance detecting distance sensor, the first contact detecting distance sensor 31, and the second contact detecting distance sensor is out of order.

(Embodiment 3) The boarding bridge 1 according to this embodiment has substantially the same configuration as the boarding bridge 1 of the first embodiment.

Now, a process of mounting the cab 9 of the boarding bridge 1 on the door 13a of the aircraft 13 using the boarding bridge control device according to this embodiment will be described. Here, it is assumed that the boarding bridge 1 is in the standby position (solid boarding bridge) as shown in FIG.

First, the operator who gets into the cab 9 pushes down the operation lever 39 toward the door 13a. By operating the operation lever 39, the drive wheel 17 rotates on the spot until the traveling direction matches the tilting direction of the operation lever 39. After that, the drive wheels 17 travel straight in the tilting direction at a rotation speed of 20 Hz.

Next, when the drive wheel 17 is linearly moving toward the mounting position, the first distance detecting distance sensor 29 is detected.
When the detection result of is Yes, the drive unit 53 reduces the rotation speed of the drive wheels 17 from 20 Hz to 6 Hz.

Next, the driving wheel 17 further linearly moves toward the mounting position, and the first contact detecting distance sensor 31 and the second contact detecting distance sensor 31 are moved.
Either or both of the distance sensors for contact detection are Yes
When it becomes, the drive unit 53 changes the rotation speed of the drive wheels 17 to 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 is Yes, the detection result of the other contact detection distance sensor is also one of the contact detection distance sensors. Yes, a little later than the distance sensor. As a result, the linear movement of the drive wheels 17 is completed, and the boarding bridge 1 reaches the mounting position as shown in FIG. As described above, the mounting of the boarding bridge 1 on the aircraft 13 is completed. At this time, if the detection result of the second distance detecting distance sensor is still No, the warning lamp 43 blinks.

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 detecting distance sensor is out of order.

In the present embodiment, it was possible to know that the second distance detecting distance sensor is out of order, but naturally it is necessary to know that the first distance detecting distance sensor 29 is out of order. You can also
