BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below in detail with reference to the drawings. The present invention is not limited to this embodiment.

FIG. 1 is a diagram showing a schematic configuration of a remote control system according to an embodiment of the present invention. This remote control system 100 includes an approach angle indicator light 2 installed at a heliport.
01, landing area illumination light 202, position indicator light 203, boundary light 204, boundary light-attached land area illumination light 205, boundary guidance light 206, position indicator light 207 (hereinafter collectively referred to as "heliport illumination light fixture 200"). ), A heliport lighting control panel 300 that controls lighting and extinguishing of the heliport illumination lamp 200, and a control signal that controls lighting and extinguishing of the heliport illumination lamp 200, and sends a control signal to the heliport lighting control panel 300. The VHF reception control device 400 for sending and the aviation radio transmission / reception by the pilot operation, which is mounted on the helicopter 500, transmits a control signal for controlling the turning on / off of the heliport lighting fixture 200 on the radio wave of the aviation radio. VHF transceiver device for aircraft station.

The heliport illuminating lamp 200 is appropriately arranged in the heliport. The approach angle indicator light 201 is an auxiliary light for safely and smoothly guiding the landing of low speed and high angle approach, which is a characteristic of the helicopter 500. The approach angle indicator lamp 201 emits light of three colors, for example, when the approach angle is too low when it is red, when the approach angle is too high when it is yellow, and when it is blue. Indicates that the vehicle is approaching at a safe approach angle.

The landing area illumination lamp 202 is an illumination for illuminating the landing surface itself having a narrow helipad so that the heliport can be visually recognized from the sky even at night. The landing area illumination lights 202 are appropriately arranged along the four corners of the square landing surface and along the edges of the square, and have sufficient illuminance for the pilot to visually recognize from the sky at night. Further, since the illuminance of the landing area illumination lamp 202 is high, it is dazzling when viewed directly. Therefore, an eaves portion is attached so that the light beam itself is not directly visible to the pilot.

The position indicator lamp 203 is a small-sized lamp for blinking the display so that the pilot can see the heliport reliably.

Similar to the landing area lighting 202, the boundary lights 204 are appropriately arranged along the four corners of the square landing surface and along the edges of the square, and the edges are surely visible to the pilot to reduce the burden of approaching the landing. It is a lighting to reduce the minimum.

The boundary light-attached land area illumination light 205 is an illumination in which the landing area illumination light 202 and the boundary light 204 are integrated, and the boundary light 204 is provided on the upper side of the landing area illumination light 202. It has been configured.

Similar to the landing area illumination light 202, the boundary guidance lights 206 are lights that are appropriately arranged along the four corners of the square landing surface and along the edges of the square, and indicate the approaching / leaving direction. There is also a type in which the boundary guidance light 206 is directly embedded in the landing surface.

The position indicator lamp 207, like the position indicator lamp 203, is a small illumination for blinking the display so that the heliport can be visually recognized by the pilot.

The heliport lighting control panel 300 is a control panel that realizes a function as remote control means for controlling the controlled object when the received radio wave contains a control signal, and is transmitted from the helicopter 500 side. The heliport illumination lamp 200 is controlled to be turned on and off according to the control signal as described later.

The VHF reception control device 400 is a reception control means for receiving a radio wave carrying a control signal for controlling a control target transmitted from a VHF transmission / reception device for an aircraft station, which will be described later, mounted on the helicopter 500. A radio wave carrying a control signal transmitted from the side is received and sent to the heliport lighting control panel 300.

In addition, VHF [Very Hi
gh Frequency] band radio waves are used. In the present invention, 118 to 121.4 and 121.6 to 1 according to the Radio Law.
Radio waves in the frequency band of 35.975 Mz are used. On the other hand, UHF band radio waves are used in military aviation radio, but either case may be used.

The reception frequency is preferably, for example, a frequency used by a control tower that communicates when taking off and landing on a heliport. If you set the frequency like this,
When the pilot operating the helicopter 500 makes contact with the control tower at the time of landing, it becomes possible to appropriately perform the lighting operation of the heliport illumination lamp 200 before the contact is started, during the contact, and after the contact.

For example, as will be described later, if a press talk switch, which will be described later, is clicked five times as a trigger, if it is set as lighting control of the lighting fixture 200, the pilot will communicate with the control tower and the heliport lighting fixture. It becomes possible to light 200.

The helicopter 500 is equipped with a VHF transceiver device for an aircraft station, which will be described later, which is operated by a press talk switch, which will be described later. VH for this aircraft station
The F transmitter / receiver is a device that communicates with the controller by aviation radio during takeoff and landing. In the embodiment of the present invention, in particular, the takeoff and landing of heliports and runways is carried on radio waves in the frequency band for aircraft stations. It is a device capable of transmitting a control signal for controlling a controlled object such as an illumination lamp installed in a facility.

Further, this VHF transceiver for aircraft station has a press talk switch, as will be described later. This press talk switch is interlocked with the pressing of a button button (not shown) attached to the tip of the control stick, etc., when the button (not shown) is pushed up when it is off, the aviation radio reception state is shown when it is on. It is a switch for setting the transmission state in the depressed state. When transmitting voice over aviation radio, the pilot speaks with the press talk switch turned on.

In particular, in the VHF transmitter / receiver for an aircraft station according to the embodiment of the present invention, as will be described later in detail, turning on / off of the heliport illuminating lamp 200 is controlled by using ON / OFF of the press talk switch. The control signal for performing is input and transmitted.

That is, the pilot on board the helicopter 500 quickly turns the press talk switch on and off within a few seconds to quickly switch the VHF transceiver for aircraft station between the receiving state and the transmitting state, and press the press talk switch. The control state is commanded by the number of pulse waves generated at the moment of turning on. This pulse wave is generated as a radio wave because it is generated when the VHF transceiver for aircraft station is in the transmitting state.

When the VHF reception control device 400 receives the radio wave transmitted from the helicopter 500 side, the number of pulse waves for several seconds is counted as described later, and if the number is a predetermined number, Since it is a control signal, the heliport lighting control panel 300 is operated to turn on or off the heliport lighting fixture 200.

Since all the heliport lighting fixtures 200 are lights necessary for takeoff and landing, they are not normally illuminated selectively, but they are not limited to ordinary applications and may be selectively illuminated or extinguished. For example, only the landing area illumination lamp 202 is turned on to be used as an outside light while the helicopter is already landing. If the number of pulse waves in this case is defined as 6, the pilot can remotely operate the helicopter 500 by clicking the press talk switch 6 times.

Further, the time when the heliport lighting fixture 200 is turned on is measured, and when a preset time (for example, 15 minutes) has elapsed, the heliport lighting fixture 2
It is preferable to turn off 00. Helicopter 50
Time may be measured from the time 0 takes off from the heliport. In this case, a sensor for detecting the takeoff of the helicopter 500 is installed in the heliport.

The DC conversion amplifier 409 includes a detector 40
The low frequency voltage output from 6 is converted into a DC voltage and output to the counter control circuit 410. As described in detail above, the counter control circuit 410 counts the pulse wave of the DC voltage and outputs the lighting signal or the extinguishing signal as the control signal to the lighting / extinguishing control circuit 301.

As a result of counting the pulse waves, the counter control circuit 410 determines that the lighting signal is a predetermined number (for example, 5), and turns on the RY 411 to send the lighting signal to the lighting / extinguishing control circuit 301. Further, as a result of counting the pulse waves, when a predetermined number (for example, three) of the pulse waves are determined to be the extinguishing signal, the RY 412 is turned on, and the extinguishing signal is sent to the lighting / extinction control circuit 301.

The figure explaining operation | movement when 0 lands. (D)
FIG. 7 shows a diagram for explaining the operation when the helicopter 500 takes off from the heliport H.

(A) When landing on the heliport H, when the helicopter 500 comes over the heliport (in the radio range), the pilot transmits a control signal for turning on / off the press talk switch 602 to turn on the illumination.

(B) The VHF reception control device 400 receives the radio wave transmitted from the helicopter 500 side, and causes the heliport illumination control panel 300 to turn on the heliport illumination lamp 200. This allows the pilot to enter the heliport H aiming for the light of the heliport illumination lamp 200.

(C) The pilot is a helicopter 500
Land on Heliport H. At this time, since the heliport lighting fixture 200 is lit, it is possible to land safely and reliably.

(D) When taking off from the heliport H, the helicopter 500 is taken off, and the pilot transmits a control signal to turn on / off the press talk switch 602 to turn off the illumination. The electric wave transmitted from the side is received, and the heliport lighting control panel 300 turns off the heliport lighting fixture 200.

Finally, the procedure performed by the pilot will be described. FIG. 6 is a flow chart for explaining the procedure for turning on / off the illumination performed by the pilot in the embodiment of the present invention.

The pilot first sets the transmission frequency to the reception frequency of the heliport to land (step S1),
The press talk switch 602 is operated to click five times, for example, for five seconds (steps S2, 3).

Then, it is confirmed that the heliport illuminating lamp 200 has been turned on (step S4), and the landing is performed while confirming the safety (step S5). After that, the heliport lighting fixture 200 is automatically turned off after a lapse of a predetermined time (for example, after 15 minutes) (step S6).

On the other hand, when it is desired to turn off the light at the time of takeoff or after some work, for example, a control signal for continuously lighting the light may be transmitted. For example, the press talk switch 602 is operated and clicked twice within 5 seconds.
In this case, the heliport lighting control panel 300 may be set to continue lighting when there are two pulse waves within 5 seconds.

Then, at the time of takeoff or when it is desired to turn off the light immediately (step S6), the pilot first sets the transmission frequency to the reception frequency of the heliport (step S7),
The press talk switch 602 is operated and, for example, clicked three times within 5 seconds (steps S8, 9). Then, it is confirmed that the heliport illuminating lamp 200 is turned off, and the process ends (step S10).

Therefore, according to the above-described embodiment, the pilot can easily remotely control the lighting of the illuminating lamp, which reduces the burden on the operator of the heliport, and the unmanned heliport. Even at night, you can take off and land.

In the above-mentioned embodiment, the lighting / lighting-off of the helicopter lighting equipment has been described. However, the lighting / lighting-out of the runway lighting equipment can be processed by the same configuration as that of the heliport lighting system. .

Further, in the above-described embodiment, the case where the control target is the lighting system in which the control target is the illumination lamp is remote-controlled, but the present invention is not limited to this. For example, the control target is a fence surrounding the heliport, and the fence is collapsed. It may be controlled to stand up.

For example, when a helicopter is not landing on a heliport, there is a helicopter in which a fence is set up to prevent people and other objects from entering. In particular,
The helipad installed on the roof of the building has a small site,
In the past, a fence was set up at the very end of the helipad so that the heliport worker could knock down the fence when the helicopter landed to ensure landing safety. Also in this case, according to the remote operation method and the remote operation control device of the present invention, the pilot can operate the trigger to fly down the fence during flight.

Note that the same processing as in the case of the above-described illumination lamp may be performed, and the fall / inversion of the fence may be the control target instead of turning on / off the illumination lamp. Further, in the above-described embodiment, the case where the heliport illumination lamp 200 is turned on has been described as the case of night, but the present invention is not limited to this, and may be turned on when necessary. For example, there may be weather that requires lighting.
