Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an aircraft type/aircraft position determination device that automatically determines the aircraft type and aircraft position at the start of cleaning using an aircraft cleaning system. The following methods were used to determine whether the aircraft was placed in a predetermined position or not.

(1) Navigation a) - Shine infrared light on the aircraft and judge based on the blocking situation.

(2) Shine infrared light on the aircraft and judge based on the reflection status.

(3) Judgment is made by pattern recognition of DI body projection.

In the case of (1), since the r+i distance between the infrared emitting side and the receiving side cannot be long, the emitting side device and the light receiving side device should be placed on both sides of the aircraft, and in the vicinity of the aircraft. The infrared light emitting/receiving device becomes an obstacle when transporting the equipment into and out of the equipment. Furthermore, it is not possible to confirm the model and fixed position with only one device facing each other, and it is necessary to install a pair of devices, and these devices themselves become a major obstacle.

In the case of (2), since the surface of the aircraft body is not 312 mm, a diffuse reflection type device (infrared emitting part and light receiving part are integrated) is used, but the allowable distance between this device and the reflecting object is the maximum. It is about 1.5 meters, and this device i:ff
i will be placed near the aircraft, and as in case (1), it will become an obstacle when carrying in and out of the aircraft.In addition, this device should be buried in the ground so that it does not become an obstacle when carrying in and out of the aircraft. Another method is possible, but there are problems with rain and dust.

In the case of (3), it is an indirect determination method and is inferior in reliability.

An object of the present invention is to automatically determine the model of an aircraft placed in an aircraft cleaning device, and to automatically determine whether the aircraft is placed in a predetermined position. The object of the present invention is to provide a determination device.

The feature of the present invention is that the aircraft is
A plurality of footboard switches are buried in the ground, and the aircraft type is determined based on the situation in which the airplane wheels step on these footboard switches, and whether the aircraft is in a fixed position or not is determined.

An embodiment of the present invention will be described below with reference to the drawings. 1st
The figure is a perspective view showing the aircraft cleaning equipment and its position In: In Figure 1, the cleaning area of the aircraft 1 is
The fuselage section is divided along the aircraft axis into a fuselage section before the main wing 2, an intermediate fuselage section that includes the upper surface of the main R2, a rear fuselage section that includes the tailboard 3, and an intermediate fuselage section that includes the lower surface of the main wing. On the other hand, each cleaning area divided into right and left sides is cleaned by each cleaning machine which is adapted to the respective shape.

The aircraft 1 is moved along the guideline 4 by a tug (not shown), etc., and comes to a stop at the 1'L neck of the crab. Both sides 1i of aircraft 1 (1st page fil

Figure 3 shows a plurality of footboard switches 21 buried in the aircraft cleaning equipment area corresponding to the positions of the wheels in Figure 2.
In particular, it shows the situation in which the footboard switch 21 is pressed down by the wheels of the aircraft type B. Points 81 to B4 indicate the wheel positions of machine rut 13, and I''! is the front wheel NB2 is the left rear wheel, B3 is the right rear wheel, I3 is the front wheel
4 indicates the position of the center rear wheel. If one or more of the footboard switches 21 (marked by diagonal lines) are pressed down on each of the front wheel, left rear wheel, center rear wheel, and right rear wheel, then the aircraft is considered to be in the correct position according to the logical judgment device. to decide. In addition, the wheel spacing and number of wheels are determined based on the on status of multiple treadle switches, and the model is determined.
Set the time.

FIGS. 4 and 5 show an example of a tread switch 2. This tread switch 21 includes a tread 23 whose foot is inserted into a recess 22a provided in a foundation 22, and
3, and the wheels of the aircraft are the tread plates 23.
When placed on the top, there is a switch 25 that turns on the switch, and a stopper 26 that prevents the tread plate 23 from descending excessively.
When the wheels of the aircraft are placed on the treadle switch 21, the treadle 23 sinks due to Mt, the limit switch 25 is activated, and it is determined that the wheels of the aircraft are placed on the treadle switch 21. Can be detected.

According to the present invention, it is possible to automatically determine the type of aircraft and the fixed position of the aircraft body without occupying the entire ground space, so there is no problem when carrying in and out of the aircraft.

Indeed, according to the present invention, it is possible to simultaneously determine the position and position of the aircraft using the same device.

Claims (1)

[Claims] A plurality of footboard switches are buried in the area where the aircraft is placed, and when the footboard switches are stepped on by the aircraft wheels, the type of the aircraft and whether or not the body is placed at a predetermined position are determined depending on the situation. Aircraft type/aircraft position determination device.
