Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helicopter collision prevention warning method and apparatus, and more particularly, to a method in which a plurality of laser range finders are provided on an airframe, and other machines intrude into the detection range of each laser range finder. The present invention relates to a novel improvement for displaying information in real time so that a collision can be prevented.

[0002]

2. Description of the Related Art Conventionally, as a helicopter collision prevention and warning method which has been used, as a general method, a measurement distance is not particularly provided, and confirmation is performed by visual inspection of a pilot. As an advanced and expensive system, recognition by radar or wireless communication (intercommunication between aircrafts) is considered.

[0003]

The conventional helicopter anti-collision warning method is configured as described above.
The following issues existed. That is, in the case of visual observation by a pilot, it is possible to confirm the front, but it is difficult to confirm below, above, and behind, and it is also difficult in the case of fog. Also, in the case of radar radio, it is difficult to measure in all directions, and it is difficult to ensure high security.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. In particular, a plurality of laser range finders are provided on a body of a machine, and other machines that have entered the detection distance range of each laser range finder. It is an object of the present invention to provide a helicopter collision prevention warning method and apparatus that can prevent a collision by displaying information on other aircraft in real time.

[0005]

A helicopter collision prevention and alerting method according to the present invention is provided with a plurality of laser range finders on a helicopter body, and information of other machines intruding within the detection range of each of the laser range finders. Is displayed on a display unit provided in the aircraft, and the display unit displays the flight direction of the other aircraft, the distance between the aircraft and the other aircraft, and an alarm sound. It is a way to warn. Further, the helicopter collision prevention warning device according to the present invention includes a plurality of laser range finders provided in the body of the helicopter, and other machine information of other machines that are provided in the inside of the fuselage and have entered the detection distance of each laser range finder. Is displayed on the display unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of a helicopter collision prevention warning method and apparatus according to the present invention will be described below with reference to the drawings. In FIG. 1, a helicopter is indicated by reference numeral 1, and a plurality of first to fourth laser range finders 3, 3 are provided on a body 2 of the helicopter 1.
4, 5, and 6 are provided. Although the contents of each of the laser range finders 3 to 6 are not shown, another machine (not shown) which is a target in a predetermined detection angle range θ _{1 to} θ ₄ scanning method using a known laser beam. Can be detected, and when there is another machine, the reflected light of the laser beam is received and converted into an electric signal, and the display unit 7 provided in the cockpit of the body 2 is provided.
Are displayed in real time as shown in FIG.

Each of the laser range finders 3 to 6 is
As shown in Figure 1, the bottom 2a of the body 2, the front 2b, respectively provided on the top portion 2c and tail 2d, the respective detection range theta ₁ through? ₄ of the laser range finder 3-6, body 2 outside of all It is configured to cover the range.
Actually, laser range finders are also provided at both side positions of the body 2 so as to be able to detect both side portions.

The detection data detected by each of the laser range finders 3 to 6 is taken into the security control device 10, subjected to data processing and displayed on the display unit 7. In this case, as shown in FIG. 2, the position of the other device 2A with respect to the airframe 2 (own device) is within a detection distance range (θ _{1 to} θ ₄ ) when viewed from above and from the rear side. The status of the other aircraft 2A that has entered the vehicle, such as the flight direction, the distance between the aircraft 2 and the other aircraft 2A, and the like, can be displayed by a light display or an audible alarm when dangerous. The display state of the display unit 7 is configured so that the state of the body 2 from all directions can be displayed by a command.

[0009]

The helicopter collision prevention warning method and apparatus according to the present invention are configured as described above, and the following effects can be obtained. That is, by using a plurality of laser range finders provided on the aircraft, data in all directions of the aircraft can be obtained in real time, and a safe flight can be obtained. Further, the data can be visually confirmed by the display unit.
