If the weight of the cable and the drone is controlled to be placed on the pipe, the weight of the cable and the drone can be distributed to the pipe, and the drone can be easily hovered.
It is conceivable to use a wired or wireless communication means, but in the following embodiment, a case where a wired cable is used will be described.

[First transmission equipment system: FIG. 1]
The first transmission equipment system (first transmission equipment system) according to the embodiment of the present invention will be described with reference to FIG. FIG. 1 is a schematic view of a first transmission equipment system.
First, the broadcasting business transmission system according to the embodiment of the present invention is basically composed of a transmitting device (wireless relay station) and a receiving device.
The receiving device is the same as the conventional configuration.
The transmission device is composed of the first transmission equipment system described below.

As shown in FIG. 1, the first transmission equipment system includes an FPU control unit 11, an FPU head 12, an FPU dedicated cable 13 for connecting both, a drone 15 equipped with the FPU head 12, and a flight of the drone 15. Basically, it has a controller (radio control) 16 for controlling the above.

[Each part of the first transmission equipment system]
Each part of the first transmission equipment system will be specifically described.
The FPU control unit 11 and the FPU head 12 have the same configuration as the conventional one.
The FPU dedicated cable 13 is an IF cable as in the conventional case, and supplies power to the FPU head 12 and transmits a video signal.

The drone 15 includes a control unit and a battery (BATT) 15a. The power supply of the battery 15a drives the flight fan.
Then, the control unit is connected to the wireless unit, sends and receives operation signals from the controller 16, and controls the driving fan.
That is, the flight of the drone 15 is controlled by operating the controller 16.

In particular, in the first transmission equipment system, the drone 15 is mounted with the FPU head 12 and controlled to be stationary at a specific height.
The FPU control unit 11 controls the FPU head 12 so as to scan the direction of the receiving device, and when the position information of the receiving device is acquired from the receiving device, the FPU control unit 11 outputs the position information to the control unit of the drone 15 and the FPU head 12 The control unit may control the flight of the drone 15 so that is directed to the receiving head 22 of the receiving device.

Further, the drone 15 is provided with a camera, and the image taken by the camera can be confirmed on the display screen of the display unit of the controller 16. Then, the shooting direction of the camera and the direction of the FPU head 12 are the same.
As a result, when the flight of the drone 15 is controlled so that the receiving head 22 of the receiving device photographed by the camera is located at the center of the display screen of the controller 16, that direction becomes an appropriate direction for radiating the beam. In addition, this operation may be automated by using the image recognition technique of the receiving device.

In the first transmission equipment system, the controller 16 is operated to lift the drone 15 to an arbitrary height so that the FPU head 12 is stationary at a specific height. Therefore, the FPU head is lifted to an arbitrary height. Can be stopped.

[Second transmission equipment system: Fig. 2]
Next, the second transmission equipment system (second transmission equipment system) according to the embodiment of the present invention will be described with reference to FIG. FIG. 2 is a schematic view of the second transmission equipment system.
The receiving device is the same as the receiving device of the first transmission equipment system. The transmission device is composed of a second transmission equipment system.
As shown in FIG. 2, the second transmission equipment system includes an FPU control unit 11, an FPU head 12, an FPU dedicated cable 13, a drone 15, a drone control and power supply unit (FAN control + BATT) 17, and a power supply. It basically has a cable 18 and an insulating pipe 19 that can be connected.

Here, since the FPU control unit 11 and the FPU head 12 in the second transmission equipment system are the same as those in the first transmission equipment system, other configurations will be described.
The FPU dedicated cable 13 connects the FPU control unit 11 and the FPU head 12, transmits signals, supplies power to the FPU head 12, and is housed in the pipe 19.

The drone 15 includes a battery in the first transmission equipment system, but in the second transmission equipment system, the power of the drone 15 is supplied from the drone control and the power supply unit 17.
The drone control and power supply unit 17 is installed on the ground and is connected to the drone 15 via a power cable 18.
A signal line for controlling the drone 15 is attached to the power cable 18. The power cable 18 is also housed in the pipe 19.

The pipe 19 is a lightweight and extendable insulating pipe.
Further, one end of the pipe 19 has a diameter smaller than the diameter of the main body, and the portion having the smaller diameter is connected to the other end of the other pipe 19. Then, by connecting the pipes 19 in the vertical direction, the connected pipes 19 are made independent.
Further, since the FPU dedicated cable 13 and the power supply cable 18 are housed in the pipe 19, the FPU dedicated cable 13 is previously connected to the plurality of pipes 19 so as to have a height equal to or higher than the target height. Pass the power cable 18 through.

A slit may be formed in the vertical direction of the side surface of the pipe 18, and the cable may be inserted through the slit. If the cable is inserted into the slit, the required number of pipes 19 can be connected at any time while raising the drone 15.
However, the pipe 19 without a slit has higher strength than the pipe 19 with a slit.

Further, in order to reduce the weight of the cable, it is conceivable that either the FPU dedicated cable 13 or the power supply cable 18 is a bare wire.
Further, when both the FPU dedicated cable 13 and the power supply cable 18 are bare wires, the two pipes are made to stand on their own, and the FPU dedicated cable 13 and the power supply cable 18 are stored separately in each pipe. May be good.
Further, a wall for vertically dividing the inside of the pipe 19 may be formed to separate the internal space, and both cables may be bare wires.

In the operation of the second transmission equipment system, the FPU head 12, the drone 15, the FPU control unit 11, and the drone are operated by passing the FPU dedicated cable 13 and the power cable 18 through the pipe 19 with the unconnected pipe 19 laid down. Connect to the control and power supply unit 17.

While flying the drone 15 over the sky with the controller 16, insert the pipe 19 from below and connect it so that it becomes independent in the vertical direction, and when the drone 15 reaches the target height, the lowest pipe 19 is placed on the ground. Fix it to the pedestal.
Then, the flight of the drone 15 is controlled, the tip of the uppermost pipe 19 is held by the seating portion of the drone 15, the flight of the drone 15 is controlled so that the connecting pipe 19 stands upright, and the drone 15 is moved to the maximum. The drone 15 is made to fly statically at that position while being placed on the tip of the upper pipe 19.
Although the FPU head 12 is shown on the pipe 19 in FIG. 2, the seated portion of the drone 15 is actually mounted on the pipe 19.

[Control in the second transmission equipment system: Fig. 3]
Here, FIG. 3 shows how the connected pipes 19 bend in the wind. FIG. 3 is a schematic view showing a state in which the pipe of the second transmission equipment system is bent.
The wind from the left in FIG. 3 causes the tips of the drone 15 and the pipe 19 to bend to the right. In that case, by controlling the drone 15 to move to the left, the deflection of the pipe 19 can be corrected and the connecting pipe 19 can be made upright.

In this way, in the second transmission equipment system, by placing the drone 15 on the pipe 19, the loads of the FPU dedicated cable 13, the power cable 18, and the drone 15 can be distributed to the connected pipe 19. Therefore, the weight of the cable is not applied only to the drone 15, and the drone 15 can be easily made to fly stationary, and the power consumption can be further suppressed.
Further, even a small drone having a small generated buoyancy can be realized as a device because the pipe 19 supports the weight of the FPU head 12 and the like.
Furthermore, it is also useful to distribute the propulsive force of the drone not in the generated buoyancy direction (vertical to the ground) but in the front-back and left-right directions.

[Drone seating structure: Fig. 4]
Next, the seating structure of the drone 15 will be described with reference to FIG. FIG. 4 is a cross-sectional explanatory view showing the seating structure of the drone.
As shown in FIG. 4, the seating portion provided on the bottom surface of the drone 15 is a hemispherical recess 15b that covers the tip portion 19a corresponding to the diameter of the tip portion 19a of the pipe 19.
Since the tip 19a of the pipe 19 is inserted into the recess 15b of the seating portion and held, the drone 15 can fly horizontally while staying on the tip 19a of the pipe 19. Then, the drone 15 is moved in the horizontal direction to control the pipe 19 so as to be straight and self-supporting in the vertical direction.

Although not shown, a hole for penetrating the cable is formed in the center of the recess 15b of the seating portion, and the FPU dedicated cable 13 and the power supply cable 18 require each cable through the through hole. It is designed to be connected to the part.

Further, a shock absorbing member such as a coil spring may be formed at the uppermost portion or the seating portion of the pipe 19 to suppress a sudden fluctuation of the load of the drone 15.

[Pedestal structure of pipe: Fig. 5]
Next, the pedestal structure of the pipe 19 will be described with reference to FIG. FIG. 5 is a schematic view showing the pedestal structure of the pipe.
The pedestal 3 is formed with a notch 33 in which a part of the side surface is notched in the central direction. Then, a protruding portion 31 is formed on the upper surface of the pedestal 3 so that the pipe 19 is inserted and becomes independent, and the protruding portion 31 is also formed with a slit-shaped slit portion 32 corresponding to the cutout portion 33.

The FPU dedicated cable 13 is housed in the pipe 19, and when the pipe 19 is set on the pedestal 3, the FPU dedicated cable 13 passes through the slit portion 32 and the notch portion 33, and the notch portion 33 is used for the FPU only. Try to pull out the cable 13.

Specifically, while raising the drone 15, the pipes 19 are vertically connected and installed on the pedestal 3. When adjusting the length of the connected pipe 19, the pipe 19 set on the pedestal 3 is lifted and the pipe 19 is removed, or the next pipe 19 is connected and installed on the pedestal 3 again.
In the example of FIG. 5, the FPU dedicated cable 13 has been described, but the power cable 18 is also installed in the same manner.

The difference from the second transmission equipment system of FIG. 2 is that only the FPU dedicated cable 13 is housed in the pipe 19 and the FPU control unit 11 and the FPU head 12 are connected to each other.

Further, the drone 15 is equipped with a battery 15a as in the first transmission equipment system, a wireless unit connected to the control unit of the drone 15 receives an operation signal from the controller 16, and the control unit operates the operation signal. The drone 15 is flown by controlling the fan according to the signal.

In the first application example in the second transmission equipment system, the weight of the cable is only the FPU dedicated cable 13, and the weight applied to the drone 15 and the pipe 19 is lightened.
Further, since the drone 15 is configured to include the battery 15a, the FPU head 12 can be easily attached by using a general drone.
Further, by mounting the drone 15 on the pipe 19, the power consumption of the battery 15a can be suppressed, and the flight time of the drone 15 can be extended.
