AIRPORT PROVIDED WITH A BIRD REJECTING SYSTEM

The invention relates to an airport comprising a take-off / landing runway, as well as a system for chasing away birds from the vicinity of the take-off / landing runway, wherein the system comprises bird detection means and bird defenses coupled thereto, wherein the bird detection means are adapted to the presence of 15 to detect birds in different detection fields in the vicinity of the take-off / landing strip and, in dependence on this, to activate bird-repelling means directed at the relevant detection field.

20 Where reference is made here to an airport runway / runway, any other object that must remain free of birds must also be understood.

; Such a system is for use at, inter alia, an airport described in US 5,450,063. The detection means here consist of radar or microwave transmitters and receivers, and the bird defense means can emit various audiovisual signals. A problem with the known systems is that a small part of the birds is not sufficiently quenched, and that another part of the birds can be quenched such that their orientation capacity diminishes and they do not know in which direction they must fly. Particularly at airports, this can lead to potentially dangerous situations, which can result in engine damage, delays, and even serious accidents.

The invention contemplates an inexpensive and / or efficient system for dispelling birds that reduces the risk of damage, accidents and / or delays at an airport.

To that end, according to the invention, the detection fields in a first group are closer to the take-off / landing strip (or the object) than the detection fields in a second group, wherein the bird defense means of the detection fields of the first group are adapted to emit a different immune signal than the bird repellants in the detection fields of the second group. The bird defense means are arranged such that the intensity of the immune signal in the detection fields in the second group is lower than the intensity of the immune signal in the detection fields in the first group. In a special embodiment, the detection fields here extend in more than two groups along the runway, the intensity of the defense signal decreasing as the groups lie at a greater distance from the runway. The detection fields within a group here preferably extend substantially parallel to each other on either side of the take-off / landing runway. When approaching the runway, the birds first receive a less intense immune signal in this way. The birds are thereby alarmed. However, if they do not respond to the first defense signal and continue to fly, they will receive a second more intense defense signal a little later. As a result, the birds will have the experience that the unpleasant immune signals are getting stronger, and 3 they will decide to return to where they came from.

The average distance between the center of the fields in the first group and the center line of the runway is preferably 0 m to 400 m, and the average distance between the center of the fields in the second group and the center line of the runway is preferably 300 to 700 m.

The bird defense means are preferably arranged such that the transmitted immune signals are directed away from the runway.

In a second embodiment, the defense signal of the bird defense means in the detection fields in the second group is a different signal than the defense signal of the bird defense means in the detection fields in the first group. The immune signals may, for example, comprise a sound signal, a light signal, a gas cloud and / or a liquid spray.

20

The characteristics of the first and second embodiments can also be combined, that is to say that the signal in the second group is of a different type (ie of a less intense type) and has a lower intensity, whereby an extra effective system can be obtained .

At least one detection field furthermore preferably extends for at least one end face of the runway, more preferably several detection fields belonging to 30 different groups. The remaining detection fields are preferably elongated and each extends parallel to the runway.

4

In the preferred embodiment, the bird detection means comprise radar means. A particularly suitable device that can be used for this is the BirdDeter ™ bird chase system from Vigilance Technologies (www.birddeter.com.au). The technical operation of such a detection system is described in more detail in the international patent application WO 95/08126. Alternatives to radar detection means may include microwave detectors, vibration detectors, sound detectors or cameras. The bird detectors preferably comprise pairs of transmitters and receivers that are each placed at one end of each elongated detection field. The length of the detection fields can be 200 m to 800 m. The transmitters in nearby detection fields are preferably set to 15 different transmission frequencies in order to prevent mutual interference and interference.

An alternative detection system is, for example, the Passive EO Radar - Perimeter Defense system from Magna BSP, where an area around one point is observed stereoscopically with a video camera whose images are analyzed for motion. In that case, the detection fields according to the invention are defined by software in the observed area.

25

The invention further relates to a system for dispelling birds from the vicinity of a runway at an airport, the system comprising bird detection means and bird defense means coupled thereto, wherein the bird detection means are adapted to detect the presence of birds in different detection fields. detect the proximity of the take-off / landing runway and, depending on it, activate bird defense means 5 which are aimed at the relevant detection field.

The invention furthermore relates to a method for dispelling birds in the vicinity of a runway at an airport, wherein bird detection means are coupled to bird defense means, wherein the bird detection means detect the presence of birds in different detection fields in the vicinity of the take-off detecting runway and, in dependence thereof, activating bird defense means directed at the relevant detection field.

The invention will be further elucidated on the basis of an exemplary embodiment shown in the figure, in which a schematic perspective view of a runway with a system for chasing birds is shown.

According to the figure, the system consists of two groups of detection fields 11L, 24 R, which are arranged parallel to the runway 1 on both sides. In the figure, the runway 1 is divided into sections by means of guide lines that indicate the length of the detection fields. The first group comprises the detection fields 11L..14L and 11R..14R. The second group comprises the detection fields 21L..24L and 21R..24R. The first group of detection fields 11L..14R is arranged approximately 200 meters away from the center line of the runway 1. The second group of detection fields 21L..24R is arranged at approximately 500 meters distance from the center line of the runway 1.

A radar transmitter 2 and radar receiver 3 are arranged at the ends of each detection field 11L-24R. Radar systems from, for example, Vigilance Technologies provide such a radar detection field over a length of up to 600 meters, wherein the radar transmitter 2 and the radar receiver 3 are placed at a height of 6 meters. This is about radar detection with waves in the 2.4 GHZ band. Near receiver 3 of a detection field, a transmitter 2 of a neighboring detection field of the same group is placed, which transmits to radar receiver 3 at the other end of that detection field. This is how chains of detection fields are set up. Because the frequencies of the radar transmitters 2 differ in neighboring detection fields 10, mutual interference can be prevented.

The detection of a bird 5 in a detection field is realized via analysis of the received radar signal on the basis of software pattern recognition. If there is a recognition on the basis of parameters set in the software program, the defense unit 4 is automatically activated either via a cable or radiographically within 1 to 2 seconds. The arrow at each defense unit 4 indicates in which direction the defense should take place; 20 which is directed towards the approaching bird 5 and away from the runway and covers at least the entire detection field. The defense unit 4 may consist of a directional loudspeaker capable of reproducing amplified sounds stored in a playback module (including a chip and a D / A converter).

25 The sound can be the sound of a gunshot followed by the sounds of fear from a bird 5.

The defense units 4 in the first group of detection fields 11L, 14R can reproduce a more intensive sound than the defense units 4 in the second group 21L, 24R, because the volume has been increased or because more gunshots with fear cries are being displayed. The signals may also be of a different nature, for example a moving green laser light, such as 7 the TOM500 from the French company LORD Ingenierie (www.lord-ina.com/fr/actuproduits.htm).

In this arrangement, it is intended that a bird that is detected in the second group of detection fields is driven away by the activation of a defense unit 4 and kept away from the runway 1. If that does not happen and the bird 5 still flies further towards the runway, then the bird 5 can then be detected in the first group of detection fields 10 and be driven away there by a defense unit 4.

The choice of different, consecutive immune signals that can depend on the detection position of the observed bird 5 relative to the runway 1 makes it possible to keep birds 5 away from the runway 1 sequentially and automatically as they approach the runway 1. By successively increasing or increasing the intensity of the negative stimulus for the bird 5 or the quality of the stimulus for the bird 5, the deterrence can thus increase as the bird approaches the runway 1. In this way the chance that a bird 5 does not fly near or over the runway 1 can thus be increased.
