Description

[0001] Aircraft Collision Prediction System [

The present invention relates to a system for predicting collision of an aircraft, and more particularly, to a system for monitoring movement of two or more aircraft and predicting collision of an aircraft using relative distance and velocity information of each airplane. Accordingly, the aircraft collision prediction system according to the present invention has the effect of predicting the collision probability of the aircraft faster and more reliably than the conventional one by reducing the amount of calculation required for predicting whether or not the aircraft collided.

Today, airplanes are widely used as one of the typical transportation means for automobiles, ships and the like. Such aircraft are widely used not only as transit vehicles for intercontinental or intercontinental transportation, but also as means of transport for long-distance transport.

The types of aircraft include a fixed wing system that uses a lift generated by running a fixed wing in the air, and a flywheel system that uses a lift generated by rotating a wing such as a propeller of a helicopter.

Most of the aircraft that are used as dual modes of transportation are configured to carry a large number of people or materials, and their size and volume are also very large. As a result, there is a problem that an aircraft in operation in the air is very difficult to turn in a fast direction.

Especially, the mechanical performance of the aircraft was developed to be close to perfection from the 80 's. However, preventing airborne collision with only a single decision by the pilot has its limits in various current and public situations. For this reason, it is required to study the aviation safety management plan which can improve the operational environment of the pilots as well as prevent airborne collision of the airborne control system and operate it integrally in order to prevent airborne collision.

Accordingly, the ATCS (Air Traffic Control System) controls the flight information of the aircraft. When a collision is predicted, the ATC sends a collision warning message and an up / down or left / right turning instruction message to the pilot Avoid airline collision.

However, such a system requires a large amount of computation to determine whether or not a collision occurred. Actually, on May 1, 2014, at the LA Airport in the United States, the computer of the Air Traffic Control Center computed to prevent collision between U2 high- There was a problem that the overhead system was paralyzed in the entire airport due to overload during the execution.

[0031] 2 shows only a main technical configuration of the control system 1 according to the present invention, and includes a transmission / reception unit for transmitting / receiving data information according to an embodiment or an application example, an input unit for acquiring additional input information from a user or the like, An output unit for outputting various calculation results, and the like.

The dangerous area setting unit 10 and the attention area setting unit 20 respectively set the areas within the danger distance and the caution distance as the dangerous area A and the attention area B based on the first aircraft 100, For this purpose, the dangerous area setting unit 10 and the attention area setting unit 20 may include a separate receiving unit (not shown) for receiving the positional information from the first airplane 100 to acquire the current position information of the first airplane 100, And the like.

In the present invention, the risk area A refers to a region having a substantially high risk of collision, and the attention area B indicates an area where the risk of collision is not higher than that of the danger area A, do. Therefore, as shown in FIG. 1, the danger zone A is set to be included in the attention zone B. That is, the danger distance for each aircraft is set to be smaller than the caution distance.

At this time, the danger distance and the caution distance for each aircraft can be set in advance by the manager or the like, and the value can be set differently according to the state information of the aircraft. Specifically, since each aircraft is different in size, serviceable speed, priority information, etc., the danger distance and the attention distance for each aircraft can be set differently based on the above-described information.

However, this is only a diagram for easy explanation, But is not limited thereto. In addition, those skilled in the art can understand that the present invention can be implemented in a modified form from a technical configuration of FIG. 1 and FIG. There will be.

The relative distance / speed calculating unit 30 calculates the relative distance / speed between the first aircraft 100 and the second aircraft 200 and the relative distance between the first aircraft 100 and the second aircraft 200, The relative speed of the second aircraft 200 relative to the second aircraft 200 is calculated. 1, the control system 1 monitors the movements of a plurality of aircraft, and when a particular aircraft enters (approaches) the attention area of the first aircraft 100, the first aircraft 100 100 and the second aircraft 200 and the relative speed of the second aircraft 200 with respect to the first aircraft 100 are calculated.

At this time, the relative distance / speed calculating unit 30 may calculate relative distance and relative speed information through various methods. For example, the relative distance / speed calculating unit 30 may calculate the relative distance of the airplane using the position information of each aircraft sensed through the separate radar equipment. Also, the relative distance / speed calculating unit 30 may calculate the relative speed of the airspeed by using the driving information received from each aircraft. Alternatively, the estimated speed information for each aircraft may be calculated based on the observed flight information for each aircraft to date, and the relative speed of the airline period may be calculated based on the estimated speed information.

In the aircraft collision prediction system 1 according to the present invention, various methods other than the above can be used to calculate the relative distance and speed of the air travel period, and the present invention is not limited to the above embodiment.

The collision predicting unit 40 predicts collision between the first aircraft 100 and the second aircraft 200 using the relative distance and relative speed information calculated by the relative distance / speed calculating unit 30 . The relative distance / speed calculation unit 30 calculates the relative distance / speed based on the calculated relative distance and relative speed information, and determines whether the direction information on the relative speed of the second airplane 200 is a dangerous area of the first airplane 100, It is possible to predict whether the first aircraft 100 and the second aircraft 200 collide with each other.

In other words, the aircraft collision prediction system 1 according to the present invention can predict the collision of an aircraft (for example, the second aircraft 200) in the attention area of a specific aircraft (e.g., the first aircraft 100) It is determined whether or not the other aircraft (for example, the second aircraft 200) is expected to pass through the dangerous area of the specific airplane (for example, the first airplane 100) based on the determination result, .

More specifically, the collision prediction unit 40 of the aircraft collision prediction system 1 estimates collision using the relative distance and relative speed information of the second aircraft 200 with respect to the first aircraft 100 The following calculation process can be performed.

First, the collision prediction unit 40 predicts a first line connecting the first aircraft 100 and the second aircraft 200 and a second line segment connecting the second aircraft 200 to the dangerous area of the first aircraft 100 Of the first aircraft 100 and the second line segment connecting the first aircraft 100 and the second aircraft 200 so that the relative distance between the first aircraft 100 and the second aircraft 200 and the relative distance between the first aircraft 100 and the second aircraft 200, 2 the stamp between the direction information on the relative speed of the aircraft 200 2 calculates the size of each (θ _r). Various methods can be applied to calculate the magnitudes of the first angle [theta] and the second angle [theta] _r . For example, the magnitudes of the first angle? And the second angle? _R may be calculated according to the following equations (1) and (2).

(Where _Rc is the critical distance for the first aircraft 100, _Rw is the attention distance, and the relative distance between the first aircraft 100 and the second aircraft 200 at present)

(Where r _AB is the relative distance of the first aircraft 100 to the second aircraft 200 and v _BA is the relative speed of the second aircraft 200 to the first aircraft 100)

The collision prediction unit 40 predicts the collision of the first aircraft 100 and the second aircraft 200 using the magnitude information of the first angle θ and the second angle θ _r obtained through various methods as described above, It is possible to judge whether or not there is a collision. For example, when the magnitude of the first angle? Is greater than the magnitude of the second angle? _R , the collision prediction unit 40 predicts that the second aircraft 200 is in dangerous area of the first aircraft 100 It is predicted that the possibility of collision is high. In contrast, when the magnitude of the first angle? Is less than the magnitude of the second angle? _R , the collision prediction unit 40 predicts that the second aircraft 200 is in dangerous area of the first aircraft 100 It can be predicted that the possibility of collision is low because it is predicted not to pass.

In the present invention, the relative distance / speed calculating unit 30 and the collision predicting unit 40 can operate at regular intervals when the second aircraft 200 is positioned within the attention area. Since the possibility of collision between the first aircraft 100 and the second aircraft 200 is predicted to some extent when the second aircraft 200 is located within the caution area based on the first aircraft 100, The system 1 (relative distance / speed calculating unit 30 and collision predicting unit 40) operates at regular intervals and can predict the collision probability of the first aircraft 100 and the second aircraft 200 at every cycle have. At this time, the period may be set in advance, and the period value may be set to decrease as the relative distance value between the first aircraft 100 and the second aircraft 200 decreases.

In another embodiment of the present invention, the collision prediction unit 40 predicts collision at various stages according to the driving information of the first aircraft 100 and the second airplane 200, The same response strategy can be presented. Hereinafter, the embodiment will be described in detail with reference to FIG.
