[Problems to be solved by the invention]

However, according to the parking position display device with the above configuration, a large number of sensors as described above must be buried below the road surface of the approach road along the course of the aircraft entering the apron spot, and Not only is a complicated control circuit device required, but a great deal of maintenance and inspection work is always required in order to maintain these normal operations.

The present invention was devised in view of the above problems, and changes the visual emission color of the aircraft distance information at a predetermined distance interval for the pilot of the aircraft entering a specific apron spot. It is configured to display optically with an indicator light composed of multiple light emitters,
Eliminates multiple sensors and devices such as complicated control circuits that were buried under the road surface along the approach road, and has a low failure rate, as well as maintenance and inspection work. It is an object of the present invention to propose a parking position display method and device which can be simplified.

[Means for solving problems]

The parking position display method and device according to the present invention emit two different colored light beams that are divided into left and right or up and down with the optical axis as a center, and each light beam from one light beam region to another light beam at a predetermined distance. By arranging a plurality of indicator lights whose visual emission color changes by moving within the area in a vertical direction on one display panel, the plurality of displays corresponding to the change in the approach distance of the aircraft approaching the display panel Visualize the light as the light emission color changes sequentially from below to above and display the distance information to guide the aircraft to a predetermined parking position, and the aircraft pattern displayed in the approximate center of the display panel. The direction of the aircraft is displayed by visual parallax with respect to the direction guidance rod to correct the displacement of the aircraft. And the inner or upper light beam of one indicator light is displayed in red, for example, the outer or lower light beam of each of the other display lights is displayed in green, and the inner or upper light beam is displayed in yellow, for example. The pilots of the aircraft approaching the panel visually recognize the light emitted from the indicator light as it changes from green to yellow, or from yellow to red, etc., and the change in the visible emission color shortens the separation distance to the parking position. Is configured as an optical distance information, and a device therefor is embodied.

In addition, a directional guidance rod is projected on the front surface of the display panel to display the directional information of the aircraft by visually observing the aircraft pilot approaching the display panel with respect to the aircraft pattern displayed in the substantially central portion of the display panel. We are taking the steps of configuring.

〔Example〕

Embodiments of a parking position display method according to the present invention and a specific device for implementing the method will be described below with reference to the drawings.

1 to 3 show a first embodiment of a parking position display method according to the present invention.

That is, in the present invention, the display panel 1 to be described later has a visual height of a pilot aboard a standard aircraft, for example, 4.
It will be installed around 0m. The display panel 1 has a structure in which a plurality of pairs of display lamps 3 and 3 are arranged on the display panel 2 in a pair of left and right, and each pair of display lamps corresponds to a shortening change in the distance D to the aircraft. 3, 3 are sequentially arranged from the lower side to the upper side, and the respective optical axes L are formed so as to form a directivity angle α with respect to the approach center line a of the aircraft, and the directivity of each pair of the indicator lights 3, 3 is the above-mentioned directivity. The angle α is sequentially given an angle difference as shown in Table (1). Therefore, the optical axes L, L of the pair of left and right indicator lights 3, 3 intersect on the approach center line a. In this embodiment, the pair of indicator lights 3,
3 The mutual arrangement interval is 30 cm from the approach center line a, that is, 60
cm intervals are formed.

Thus, the indicator lamp 3 used in the present invention comprises a light emitter 11 constituted by an optical system as shown in FIG. 3, and the light emitter 11 is a focal portion of the parabolic reflecting mirror 12. The light source bulb 13 is carried by the lens 14, the lens 14 from which spherical aberration and chromatic aberration have been removed is arranged in front of it, and between the parabolic reflecting mirror 12 and the lens 14, the optical axis L of the light source bulb 13 is centered. The filter 15 is provided with different colors. The vertical and horizontal dimensions and the arrangement position of the filter 15 are determined by the focal length F of the lens 14 and the diameter of the lens 14, and the design can be changed as desired. The light emitter 11 according to the present embodiment is configured by the above optical system, and forms the inner light beam A'and the lower light beam B'which have different visible light emission colors by the colors A and B of the filter 15, respectively. Is. Therefore, when the pilot eye P is in the outer light beam A'region, the emission color of A'is visible, and when it is in the inner light beam B'region, the emission color of B'is visible. For a pilot passing across the light beams A'and B ', it functions to change the visible emission color by changing the distance, that is, by approaching the display panel 1. Further, the light emitters 11 are arranged at the rear portions of the pair of left and right display windows 4 and 4 formed on the display panel 2 of the display board 1, and the left and right pairs are displayed on the display panel 2 in plural pairs in the vertical direction. The lamps 3 and 3 will be configured.

FIG. 4 shows an example of a method of displaying the visible emission color of the indicator lamps 3, 3 which changes in accordance with the change in the distance D with respect to the display board 1, and in the display board 1 according to the present embodiment. Is the parking position, that is, the stop line is 0 m
In order to display distance information indicating the aircraft approach situation at intervals of 5 m to 5 m to 10 m, a total of 10 display lamps 3a to 3e are formed on the display panel 2, one pair each on the left and right, and a total of 10 display lamps 3a to 3e. An emergency indicator lamp 5 that is turned on by an operation of a monitor is formed in the central portion of the uppermost part of the upper part 2. In addition, an aircraft pattern 7 that is illuminated in yellow or the like is displayed in a substantially central portion of the display panel 2, and a direction guidance rod 8 protrudingly arranged in front of the aircraft pattern 7 is displayed.
It is configured such that the positional deviation of the aircraft on which the viewer, that is, the pilot who is the viewer is on board, can be displayed as direction information by the visual parallax. In this embodiment, among the above-mentioned indicator lamps 3a to 3e, the four pairs of indicator lamps 3a to 3d from the bottom are stop position warning indicator lamps, and the outer light beam A is green and the inner light beam B is yellow. The pair of indicator lamps 3e located at the uppermost stage is a stop position indicator lamp, and the outer light beam A has a yellow color and the inner light beam B has a red light emission color. It is composed of 11.

Thus, when the aircraft lands on the runway and enters the apron spot, the pilot confirms its position by the designated spot number display, and further by the flashlight 6 mounted on the upper part of the display panel 1 according to the present invention. Know the parking position of your aircraft. After that, the vehicle advances along the guidance line of the taxiway apron to directly face the apron spot. At this time, the direction guidance rod 8 adjusts the displacement of the vehicle itself. That is,
When the direction guidance rod 8 is viewed as shown in (a), the aircraft is on the right side of the guide line, and therefore, the direction is corrected to the left side, and when viewed as shown in (b), My aircraft is on the left side of the guidance line and I have to correct the direction to the right. At the time of the above-mentioned guidance, all the indicator lights 3a to 3e on the display panel 2 are turned on by the operation of an observer, the indicator lights 3a to 3d serving as the stop position advance notice indicators are green, and the stop positions are also indicated. The indicator light 3e, which is an indicator light, is visually recognized with a visible emission color of yellow. This visible emission color does not change when the aircraft is at a separation distance D of 45 m or more (C).
When the aircraft enters the 35m line, the pair of indicator lights 3a at the bottom changes to a visible yellow emission color, and thereafter, every 10m, the pair of indicators 3b to 3d are visually recognized as a yellow visible emission color. When reaches the parking position, the visible emission color of the pair of uppermost indicator lights 3e is visually recognized as red and stops. The emergency indicator light 4 formed in the central portion of the uppermost part of the display panel 2 is turned on by an operation of a supervisor in the event of an emergency such as overrun and stops the progress of the aircraft, and is internally illuminated with a red emission color. Is. In this embodiment, as described above, since the optical axes L, L of the pair of left and right indicator lights 3, 3 form the directivity angle α so as to intersect with each other on the approach center line a, the aircraft is When it deviates from the approach center line a, the visible light emission colors of the left and right indicator lights 3 and 3 are visually recognized differently, and it also functions as a display of direction information of the aircraft.

FIG. 5 and FIG. 6 show a second embodiment relating to the parking position display direction according to the present invention, which emits two different kinds of colored light rays which are divided in the vertical direction and each has a predetermined separation distance. In the above, the distance information is displayed by a plurality of display lamps arranged in the vertical direction in which the visible light emission color is changed by moving from one light beam area to another light beam area.

In this embodiment, the display panel 1 is installed at a position lower than the visual height H'of the pilot, that is, the pilot eye P. For example, the visual height H'of the pilot eye P is 5 for a specific model. When the height is 0.4 m, it is desirable to set the installation height H to around 4.0 m. In this case, the mounting pitch of each of the plurality of indicator lights 3 and 3 arranged on the display panel constituting the display panel 1 causes a step h as shown in FIG. This is negligible because the parallax is small. Thus, assuming that the respective indicator lights 3 and 3 are installed at 4.0 m, the angle β of the optical axis L formed by the respective indicator lights 3 and 3 corresponding to the distance D to the aircraft is , Appendix
As shown in (2), it is necessary to form the angle difference as shown in the table with respect to the optical axis L of each of the indicator lamps 3 and 3. Further, the angle β of the optical axis L formed by each of the above-mentioned indicator lamps 3, 3 becomes larger as shown in Table (3) when the pilot eye P is higher, for example, 8.7 m. . That is, when the installation height H of the display board 1 is fixed to 4.0 m, the depression angle β of the optical axis L formed by the display lamp is 4 at a distance of 20 m from the display board 1 depending on the aircraft model. It must be adjusted in the range of 0.000 to 13.22 °. Therefore, in the present embodiment, the optical axis L of each of the indicator lamps 3 and 3 can be adjusted in the vertical direction by using a conventionally known actuator which is appropriately driven by an external signal.

FIG. 7 shows an embodiment relating to an apparatus for carrying out the parking position display method according to the present invention. The display panel 2 formed on the front surface of the display board 1 as described above has a pair of left and right upper and lower parts. Five pairs in the direction, that is, four pairs from the bottom constitute the indicator lamps 3a, 3a to 3d, 3d which are the stop position warning indicator lamps, and the uppermost pair are the indicator lamps 3e and 3e which are the stopper position indicator lamps. An emergency indicator light 5 is located at the center of the top of panel 2.
Is provided. These displays etc. 3a, 3a to 3e,
3e, it is necessary to form an appropriate arrangement interval in order to avoid the light immersion phenomenon caused by lighting of the vertically adjacent indicator lights,
In relation to the vertical length of the display panel 1, for example, each indicator light 3a,
When the inner dimensions of the display windows 4 and 4 of 3a to 3e and 3e are about 80 mm, it is preferable that the distance between the optical axes L of the respective indicator lights 3a, 3a to 3e and 3e is about 170 mm.
This arrangement interval can be appropriately changed depending on the size of the vertical length of the display board 1 and the size of the display windows 4 and 4 of the respective indicator lights 3a, 3a to 3e, 3e, and is limited to the above embodiment. Of course not.

Reference numeral 7 denotes an aircraft pattern formed by a recurrence reflection tape or the like on the receding surface 2a formed in the substantially central portion of the display panel 2, and in the present embodiment, is an externally illuminated type, that is, a plurality of elements arranged in front of the receding surface 2a. It can be illuminated by the light source 9.
Further, it is the same as the conventional one that the directional guidance rod 8 is provided on the front of the aircraft pattern 7 so as to project from the display panel 2. However, in this embodiment, the direction guidance rod 8 also serves as a light-shielding plate of the light source 9, and the direction guidance rod 8 is directed on the aircraft pattern 7 due to the difference in brightness from the direction guidance rod 8 located on the aircraft pattern 7. It is designed to form the silhouette of the guidance rod 8.

FIG. 8 shows another embodiment relating to a method of constructing the aircraft pattern 7 and the direction guidance rod 8, and the display panel 2
An aircraft pattern 7 made of a colored translucent plate such as yellow is arranged on the top, and a light source (not shown) arranged inside the display panel 2 is turned on to illuminate from the inside. . In addition, the direction guidance rod 8 is also illuminated by green light or the like by an internally illuminating light source, like the aircraft pattern 7. Therefore, it is constructed so that it can be used not only day and night but also in response to various weather conditions and installation conditions. It is needless to say that a publicly known illumination method such as a lightning type, a light projecting type, or an LED type can be appropriately applied to each of the above internal illumination light sources.

In the housing forming the display panel 1, the display window 4 formed in the display panel 2 is positioned on the rear surface of the display panel 1, and the display window 4 is arranged in the same manner as shown in FIG.
It goes without saying that it accommodates the light emitter 11 formed of the optical system shown in the figure.

Further, in carrying out the second method according to the present invention,
In order to respond to the height of the pilot eye P depending on the size of the aircraft approaching the apron spot,
As shown in FIG. 9, it is also possible to support it by a well-known lifting device 10 such as a cylinder, and to vertically move it by the operation of a monitor.

〔The invention's effect〕

Since the parking position display method and the device therefor according to the present invention are configured as described above, the pilot is not required to embed a sensor below the road surface of the approach road or various facilities such as a complicated control circuit. It is possible to reliably guide the aircraft to the parking position by visually checking the optical distance information and direction information, and not only facilitate maintenance and inspections, but also contribute to cost reduction. , Which has an excellent effect.
