DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the embedded aviation beacon according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 conceptually shows an embodiment of the embedded aviation marker light according to the present invention. This embedded aviation beacon is installed along a taxiway that guides an aircraft at an airport or the like.

Referring to FIG. 1, in the embedded aviation beacon of this embodiment, a lamp portion 11 is detachably attached to an upper portion of a main body portion 10. A part of the ramp portion 11 slightly projects from the ground surface GL, and the other portion is buried under the ground surface GL. A lamp chamber 11a is formed inside the lamp unit 11, and the lamp chamber 11a is provided in the lamp chamber 11a.
b is accommodated. The lamp 11b is composed of, for example, a tungsten halogen light bulb, and functions as an aviation sign lamp for giving information of passage permission to an aircraft on a taxi way by turning on or off. This lamp part 1
The No. 1 lamp 11b is supplied with power via a power line cable arranged in a conduit 30 arranged below the embedded aviation beacon lamp.

Two holes 1 are formed in the upper part 11c of the lamp part 11.
Optical fibers 14 and 15 are passed through the holes 12 and 13, respectively, and the ends of the optical fibers 14 and 15 open upward at the upper portion 11c of the lamp portion 11. As will be described later, one of the optical fibers 14 and 15 transmits infrared rays emitted from the infrared ray emitting section 21 (see FIG. 2) of the infrared sensor detecting section 20, and other optical fiber 14 transmits the infrared rays. The fiber 15 inputs infrared rays reflected by an object such as an aircraft passing above the embedded aviation beacon, and guides the infrared rays to the infrared light receiving section 22 of the infrared sensor detecting section 20. This optical fiber 14, 15
Passes through the lamp chamber 11 a of the lamp unit 11 and is connected to the infrared sensor detection unit 20.

The other end of the infrared sensor detecting section 20 is provided below the lamp section 11, and a heat insulating material 16 is interposed between the lamp section 11 and the infrared sensor detecting section 20. Here, the reason for interposing the heat insulating material 16 is that the temperature of the lamp section 11 becomes as high as about 800 degrees when the lamp section 11 is driven. Therefore, the infrared sensor detecting section 20 may be damaged or malfunction due to the temperature of the lamp section 11. This is to prevent it.

As will be described later, the infrared sensor detecting section 20 comprises an infrared emitting section 21 which emits infrared rays and outputs the infrared rays to the optical fiber 14, and an infrared receiving section 22 which receives the infrared rays output from the optical fiber 15. Therefore, an object such as an aircraft passing above the embedded aviation beacon is detected from the detection output of the infrared light receiving section 22.

The detection output of the infrared sensor detecting section 20 is transmitted to a center device (not shown) by power line communication using a power line cable arranged in the conduit 30.

By the way, not only aircraft but also various vehicles for transporting cargo etc. pass on the taxi way in which the embedded aviation beacon is buried. In this example,
With the infrared sensor built into the embedded aviation beacon,
Detecting the distance of the object passing through the top of this embedded aerial beacon from this embedded aerial beacon, based on this distance, whether the object passing through the top of this embedded aerial beacon is an aircraft, Or identify it as another vehicle.

That is, since the height of an aircraft is greatly different from that of various vehicles that carry cargo, the distance to an object passing above the embedded aviation beacon is detected from the output of the infrared sensor. As a result, it is possible to easily identify whether the object passing above the embedded aerial beacon light is an aircraft or another vehicle.

FIG. 2 shows this operation. In FIG. 2, reference numeral 40 denotes various vehicles for carrying cargo,
40 'indicates an aircraft.

First, it is assumed that the objects passing above the embedded aviation beacon light are various vehicles for carrying cargo or the like indicated by 40. In this case, the infrared light emitted from the infrared light emitting portion 21 of the infrared sensor detecting portion 20 passes through the optical fiber 14 and the hole 12 of the upper portion 11c of the lamp portion 11 and is projected upward. This infrared ray is reflected by various vehicles 40 that carry cargo and the like, and this reflected infrared ray is reflected by the upper portion 11c of the lamp section 11.
The light is input to the optical fiber 15 from the hole 13 and is guided to the infrared light receiving portion 22 of the infrared sensor detecting portion 20 through the optical fiber 15. The infrared light receiver 22 of the infrared sensor detector 20 detects the infrared light transmitted through the optical fiber 15. Then, the distance from the output of the infrared light receiving unit 22 to the object passing over the embedded aviation beacon is detected, whereby the object passing over the embedded aviation beacon emits cargo or the like. It is determined that the vehicle is a variety of vehicles 40 to be carried.

It is also assumed that the object passing above the embedded aerial beacon is an aircraft indicated by 40 '. In this case, the infrared ray emitted from the infrared ray emitting section 21 of the infrared sensor detecting section 20 passes through the optical fiber 14 and the hole 12 of the upper portion 11c of the lamp section 11, is projected upward, and is reflected by the aircraft 40 '. Then, the reflected infrared rays are input to the optical fiber 15 through the hole 13 in the upper portion 11c of the lamp portion 11, pass through the optical fiber 15, and are guided to the infrared light receiving portion 22 of the infrared sensor detecting portion 20. The infrared light receiver 22 of the infrared sensor detector 20 detects the infrared light transmitted through the optical fiber 15. And this infrared ray receiving section 2
The distance from the output of 2 to the object passing over the embedded aviation beacon is detected, and it is determined that the object passing over the embedded aviation beacon is the aircraft 40 '. .

In the above embodiment, the lamp chamber 11
When the lamp 11b inside the lamp a is broken, the lamp portion 11 is removed from the main body 10 and the lamp 11b inside the broken lamp chamber 11a is replaced. Here, if the optical fibers 14 and 15 between the lamp unit 11 and the infrared sensor detection unit 20 do not have slack, the lamp unit 11 cannot be removed from the main body unit 10. Therefore, in this embodiment, a predetermined slack is formed in the optical fibers 14 and 15 between the lamp section 11 and the infrared sensor detecting section 20, so that when the lamp 11b in the lamp chamber 11a is replaced, The main body 10 without cutting 14 and 15
The lamp portion 11 can be removed from the.

Further, in the above-mentioned embodiment, the infrared light emitting portion 21 of the infrared sensor is constructed to emit infrared light in the wavelength region containing less energy in the sunlight, whereby the object can be illuminated even in the sunlight. It is configured so that it can be reliably detected.

[0029]

As described above, according to the present invention,
Since an infrared sensor is incorporated in an embedded aviation beacon light buried in the ground along a taxiway that guides an aircraft, and the infrared sensor is configured to detect an aircraft passing above, a special protrusion from the ground It is possible to detect an aircraft traveling on a taxiway without installing equipment, and by using this detection output, collisions between aircraft traveling on a taxiway can be prevented without deploying a large number of guards.
