DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is an overall view of this embodiment. The helicopter 1 and the landing target position of the ship 3 are connected by an induction cable 2 having a built-in electric wire. Wired information can be transmitted between the helicopter side and the ship side via an electric wire built in the induction cable 2.

FIG. 2 is a block diagram of the device A on the helicopter side. The helicopter 1 is equipped with a cable winder 7, an input / output interface 4, a cable length detection device 5, and an autopilot device 6. The cable winder 7 keeps the tension of the induction cable 2 at a predetermined value by winding and feeding it. The input / output interface 4 transmits / receives information to / from a ship-side device, which will be described later, through an electric wire built in the induction cable 2, and also transmits information to the automatic control device 6. The cable length detection device 5 detects the length of the lowered cable by the rotation of the cable winder 7 and sends it to the input / output interface 4. The automatic control device 6 controls the airframe by inputting a control command signal, which will be described later, sent from the device on the ship side through the input / output interface 4.

FIG. 3 is a block diagram of the apparatus B on the ship side. The boat 3 is provided with a cable inclination detection device 10, an input / output interface 9, and an arithmetic processing device 11. The cable inclination detection device 10 includes a connector portion 10a connected to the induction cable 2 and a connector angle detection portion 10b, detects the inclination of the connector portion 10a connected to the induction cable 2, and outputs the signal to the arithmetic processing device 11. I am supposed to send it. The connector portion 10a is electrically connected to the electric wire in the induction cable 2 and the input / output interface 9. Therefore, the input / output interface 9
Exchanges information with the helicopter-side device and the arithmetic processing device 11 through the guide cable 2 and the connector portion 10a of the cable inclination detection device 10. The total calculation processing 11 is the cable inclination detecting device 1
The signal of the inclination of the induction cable detected by 0, and the signal of the length of the induction cable transmitted through the electric wire in the induction cable 2 detected by the cable length detection device 5 on the helicopter side and the connector portion 10a are input. As a value, helicopter 1
And the relative position of the ship 3 is calculated, and a steering command signal of the helicopter that causes the guide cable 2 to be vertical according to the relative position is output.

In the present embodiment, the cable hoist 7 on the helicopter side tensions the induction cable 2 connected between the helicopter 1 and the planned landing position of the ship 3 to a predetermined tension. As a result, the cable length detected by the cable length detection device 5 and the cable inclination detected by the cable inclination detection device 10 are accurately detected.

As shown in FIG. 4, the signal of the length of the induction cable detected by the cable length detecting device 5 is processed through the input / output interface 4, the electric wire in the induction cable 2 and the input / output interface 9. To device 11,
The signal of the inclination of the induction cable detected by the cable inclination detection device 10 is input to the arithmetic processing device 11, and the arithmetic processing device 11 calculates the relative position between the helicopter 1 and the ship 3 based on the both signals. , And calculates and outputs a control command signal 12 of the helicopter 1 such that the guide cable 2 becomes vertical in accordance with the relative position. This signal is transmitted to the helicopter-side autopilot device 6 via the input / output interface 9, the electric wire in the induction cable 2, and the input / output interface 4.

In this way, the helicopter 1 automatically moves the guide cable 2 to the vertical position, that is, the helicopter 1
Is guided to a state in which it is positioned vertically above the target landing position and descends, so that the ship can be safely and efficiently landed on the ship 3.

In the above embodiment, the arithmetic processing unit 1
The pilot command signal 12 of No. 1 is transmitted to the helicopter side automatic pilot device 6 to automatically pilot the helicopter 1. However, the pilot command signal is appropriately transmitted to the helicopter side for display, and the pilot command is based on this. Can also control the helicopter. Further, although the cable inclination detecting device 10 is provided on the ship side in the above-described embodiment, it may be provided on the helicopter side.

[0016]

Industrial Applicability The present invention automatically detects the relative positions of a vertically take-off and landing aircraft and a ship, instead of the conventional method in which a pilot landes, by guiding a guide member wirelessly. And because the guide cable connected to the target landing position of the ship is transmitted to the aircraft side with a vertical control command signal, the aircraft can be guided and landed efficiently and safely, and It is possible to reduce the workload of the pilot.

Further, since the signal transmission between the aircraft capable of vertical takeoff and landing and the ship is performed by wire by the electric wire built in the induction cable, reliable landing guidance can be performed. Furthermore, by performing the signal processing by the arithmetic processing unit on the ship side, it is possible to reduce the weight increase of the aircraft.
