Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to an automatic landing position measuring device applied to a helicopter automatic landing or ship landing system.

[Conventional technology]

Conventionally, there is no automatic landing position measurement device applicable to automatic landing or landing of a helicopter or the like during flight.

[Problem that the invention seeks to solve]

Landing a helicopter in the air, especially on a swaying ship ring, is difficult, and automatic piloting is not currently available.

An object of the present invention is to provide an automatic landing position measurement device that enables accurate measurement of a landing point from a helicopter or the like in the air, and also enables automatic piloting of a soft landing taking into consideration the fluctuation of the first landing point. With the goal.

[Means for solving problems]

For this purpose, the automatic landing position measuring device of the present invention specifies the point at which a helicopter or the like should land using a laser irradiator on the ground, and includes a gimbal movable seeker installed on the aircraft side that searches for this landing point. The aircraft is characterized by a distance-measuring laser unit that accurately measures the distance between the landing point and the aircraft.

[Effect]

According to the above-described automatic landing position measuring device of the present invention, the distance between the aircraft and the landing position can be automatically measured by the distance measuring laser section attached to the gimbal movable seeker that automatically points to one landing position.

〔Example〕

The automatic landing position measuring device as an embodiment of the present invention will be explained below with reference to the drawings. Fig. 1 is a block diagram showing the entire nine devices. It consists of a side mounting device B. The helipad equipment A consists of a light scattering reflector 1 placed approximately in the center of the landing position of the helipad, and a laser irradiator 2 installed at the end of the helipad to irradiate the light with laser light. The light scattering reflector 1 has a characteristic of receiving and diffusely reflecting the laser light from the laser irradiator 2.

The laser irradiator 2 has a built-in high-power laser transmitter such as a YAG laser.

The body-side attachment device B is composed of a gimbal movable seeker and a ranging laser section 4, and the gimbal movable seeker is composed of a seeker section 3 and a servo section 5.

The servo section 5 has a gimbal movable mechanism that can sufficiently direct the seeker section 3 to the landing position.

Referring to FIG. 2, the gimbal movable seeker detects the laser beam from the light scattering reflector 1, and sends a command from the seeker section 3 to the reservo section 5 so that the seeker section 3 directs the laser beam. The servo unit 5 receives this control signal and drives the gimbal.

The seeker section 3 is directed to the laser beam. A laser transceiver with a built-in distance measuring register drives the range counter 42 and sends out a distance signal. Azimuth detector 52. The depression angle detector 52 is attached to the gimbal of the servo section 5 and sends out azimuth and depression angle signals.

That is, according to an embodiment of the automatic landing position measuring device of the present invention.

(1) A laser oscillator is installed near the helipad, and a laser beam is directed from it to a diffused reflection plate installed in the center of the helipad.

(2) A movable gimbal seeker is installed at the bottom of the helicopter to automatically point toward the diffused reflector at the center of the helipad in (1) above.

This measures the azimuth and depression angle from the seeker to the diffused reflector, that is, from the aircraft to the helipad.

(3) At the same time, the distance measuring laser section attached to the seeker in alignment with the pointing direction measures the diffuse reflector position, that is, the distance from the nine aircraft to the center of the helipad.

〔Effect of the invention〕

According to the automatic landing position measuring device of the present invention as described above in detail, the distance, azimuth, and elevation angle from the helicopter to the landing position can be freely measured with the simple configuration shown in the claims. This has become possible by incorporating automatic landing or automatic landing functions into the maneuvering system, which had previously been hindered from practical application due to the inability to measure these functions.
