Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a guidance device that guides an aircraft so that it stops at a predetermined position with an apron in an airfield.

[0002]

[Prior Art]

 Generally, in an aerodrome, an aircraft is parked in an apron for passengers getting on and off, refueling, inspection of equipment, etc., but at this time, the aircraft is guided to a predetermined stop position and accurately stopped. There is a need. When an occupant (or a worker) in the passenger compartment visually checks and stops the aircraft, it is confirmed that the loop coil embedded in the ground corresponding to the stop position of the apron and the magnetic field change in the loop coil. When a detector for detection and an indicator that is installed in a place visible from the passenger compartment of the aircraft and that displays the lighting etc. by the detection signal of the above detector are provided, and the wheel of the aircraft comes on the loop coil, It is known that a detector detects a change in the magnetic field associated therewith and operates the display based on the detection signal.

[0003]

[Problems to be solved by the device]

 However, since this conventional method is a method that detects changes in the magnetic field due to the presence or absence of wheels, a complicated circuit is required for the detector that detects changes in the magnetic field, and the wheels are positioned directly above the loop coil. The magnetic field changes even a little away from the detection range, and there is a wide range of detection accuracy, making accurate detection difficult and unsatisfactory in terms of reliability.

The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to accurately detect arrival of wheels of an aircraft guided by the above apron with a simple configuration. , To improve the stopping accuracy of the aircraft and improve its reliability.

[0005]

[Means for Solving the Problems]

 In order to achieve this object, in the invention of claim 1, a member is provided which is immersed in the ground when the wheels of the aircraft are ridden, and the proximity switch detects the immersion operation of the member.

Specifically, the present invention provides a detector for detecting arrival of wheels of an aircraft on an apron as a guidance device for guiding the aircraft to travel at an apron in an airfield so as to stop the aircraft at a predetermined stop position. , This detector has a seat plate that is open to the ground of an apron and is inserted into a groove of a size in which the wheels of an aircraft cannot be retracted, and a biasing force that pushes this seat plate out of the groove. Urging means, a moving member connected to the lower portion of the seat plate, and a groove disposed in the groove, and outputs a signal when the moving member approaches due to the seat plate being retracted into the groove. And a proximity switch.

[0007]

[Action]

 With the above structure, in the device of claim 1, in the normal state, the seat plate projects from the ground of the apron, but when the wheel of the aircraft to be stopped rides on the seat plate, the seat plate has a groove. Immerse yourself in. Along with this immersing operation, the moving member connected to the seat plate moves downward and approaches the proximity switch, and the proximity switch outputs a signal when the moving member approaches. In this way, the proximity switch detects the approaching motion of the seat plate and the moving member due to the pressure of the wheel, and the arrival of the wheel is determined based on the ON / OFF signal of this switch. The detection can be performed with high accuracy and accuracy, and the reliability can be improved.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings.

FIG. 3 shows an overall configuration of an aircraft guidance system according to an embodiment of the present invention, where Ap is an apron for an airfield, and a straight guide line Lg for guiding the aircraft Ac is provided on the ground of the apron Ap. A stop line Ls orthogonal to the line Lg and a caution line Lc (caution line) are drawn. The stop line Ls is a short line because it positions the stop position of, for example, the front wheel W of the aircraft Ac guided along the guide line Lg. The caution line Lc is for notifying the occupant (or the worker) of the aircraft Ac that he / she is approaching the stop position before reaching the stop line Ls, and has the same length as the stop line Ls. It is drawn.

The position where the guide line Lg intersects the stop line Ls is a front and rear stop position of the aircraft Ac, and the position where the guide line Lg intersects the caution line Lc is a caution position. The stop position and the caution position The detectors 1 and 2 for detecting the arrival of the wheels W at the respective positions are installed in each of them. The detectors 1 and 2 have the same configuration, and the detector 1 at the stop position will be described here. That is, as shown in an enlarged detail in FIG. 1, a bottomed rectangular groove 3 having a length of, for example, about 1 m is formed along the stop line Ls on the ground at the stop position, and the width d ( The length along the guide line L g) is such that the wheels W of the aircraft Ac cannot be immersed (see FIG. 2). A seat plate 4 having an outer shape slightly smaller than the opening of the square groove 3 is fitted in the upper part of the square groove 3 so as to be retractable. On the other hand, a square tubular frame 5 extending along the square groove 3 is fixed to the inner bottom portion of the square groove 3, and a plurality of (for example, three) shaft insertion holes 6, 6, are formed on the upper wall of the frame 5. Are formed at equal intervals in the length direction. .. which are slidably inserted into the shaft insertion holes 6, 6, ... Of the frame 5 are integrally fixed to the lower portion of the seat plate 4. Between the lower surface of the seat plate 4 and the upper surface of the frame 5, coil springs 8 located around the upper side of the frame 5 on each shaft 7 are compressed, and the springs 8 allow the seat plate 4 to move. An urging means for urging the ridge in the direction of projecting from the square groove 3 (upward) is configured.

Further, on the upper surface of the bottom wall of the frame 5, proximity switches 21, 21, ... Are attached at positions just below the shaft insertion holes 6, 6 ,. As shown in FIG. 2, each of the proximity switches 21 moves when the wheel W of the aircraft Ac rides on the seat plate 4 so that the seat plate 4 sinks into the square groove 3 and the lower end of the shaft 7 approaches. Then, it detects that and outputs a signal.

Again, as shown in FIG. 3, the outputs of the proximity switches 21 of the detectors 1 and 2 at the stop position and the attention position are both connected to the control board 22. Further, in front of the guide line Lg, an indicator 23 for indicating by lighting a colored lamp or the like is provided upright toward the aircraft Ac on the guide line Lg. This indicator 23 is connected to the control board 22. When the wheels W of the aircraft Ac guided along the guide line Lg arrive at the caution position or the stop position, the signals of the proximity switch 21 of the detectors 2 and 1 for detecting the situation are output to the control board 22. The control board 22 controls the display 23 to that effect.

In the normal state, as shown in FIG. 1, the seat plate 4 in each of the detectors 1 and 2 is caused by the biasing force of the spring 8 so that the seat groove 4 of the apron Ap has a rectangular groove. It projects above 3 from the ground, each proximity switch 21 does not output a detection signal, and the display 23 is not operated.

In this state, when the aircraft Ac is guided forward along the guide line Lg of the apron Ap and its front wheels W get on the seat plate 4 of the detector 2 at the attention position, as shown in FIG. The seat plate 4 is pushed down against the urging force of the spring 8 and is immersed in the square groove 3. With the retracting operation of the seat plate 4, the shaft 7 connected to the seat plate 4 moves downward and its lower end approaches the proximity switch 21, and the proximity switch 21 outputs a detection signal when the shaft 7 approaches. To do. In response to the detection signal from the detection switch 21, the control board 22 outputs a display signal to the display device 23, and, for example, a yellow lamp lights up on the display device 23 and a display indicating "caution" is displayed. By looking at the display of this "caution", the occupant (or the worker) can know that the aircraft Ac is approaching the stop position, and can perform operations such as deceleration.

At this time, since the seat plate 4 is long in the direction orthogonal to the guide line Lg and a plurality of proximity switches 21, 21, ... Are arranged at intervals in the length direction, the wheel W is guided. Even if it is slightly deviated from the line Lg, one of the proximity switches 21 performs the detection operation, which can be performed more reliably than the arrival of the wheel W.

After this, when the aircraft Ac further advances and the front wheels W ride on the seat plate 4 of the detector 1 in the stop position, the seat plate 4 is pushed down against the biasing force of the spring 8 and the corners are pushed down. Immerse in the groove 3. Along with this immersing operation of the seat plate 4, the same movement as described above is performed, and the proximity switch 21 outputs a detection signal. By the operation of the control board 22 which receives the detection signal from the detection switch 21, for example, a red lamp is lit on the display 23 to display “stop”, and by seeing this “stop” display, The occupant (or the worker) may immediately stop the aircraft Ac, which accurately stops the aircraft Ac at the stop position.

Therefore, in this embodiment, since the proximity switch 21 detects the approaching motion of the seat plate 4 and the shaft 7 due to the pressure of the wheel W, a complicated circuit is required to detect the arrival of the wheel W of the aircraft Ac. Is unnecessary. In addition, the detection can be performed with high accuracy and accuracy, and the accuracy of stopping the aircraft Ac at the stop position can be increased and the reliability can be improved.

[0018]

[Effect of the device]

 As described above, according to the invention of claim 1, when the aircraft is guided to stop at the predetermined position of the apron on the airfield, a groove is formed in the ground at the predetermined position of the apron and the seat plate is formed inside the groove. The seat is installed so that it can be retracted, and a moving member is connected to the seat so as to move together.A proximity switch is provided to detect the approach of this moving member. By performing the detection, a complicated circuit is not required to detect the arrival of the wheels of the aircraft guided to travel, and the detection can be performed accurately, which in turn enhances the stopping accuracy of the aircraft. The reliability can be improved.
