Description

AIRPORT PROVIDED WITH A SYSTEM FOR REPELLING BIRDS
The invention relates to an airport comprising a runway, in addition to a system for averting birds from the vicinity of the runway, wherein the system comprises bird detecting means and bird repelling means coupled thereto, wherein the bird detecting means are adapted to detect the presence of birds in different detection zones in the vicinity of the runway and to activate subject thereto bird repelling means which are directed at the relevant detection zone .
Where reference is made here to a runway of an airport, this must also be understood to mean any other object which must remain free of birds.
Such a system is described in US 5,450,063 for application at, among other locations, an airport. The detecting means herein consist of radar or microwave transmitters and receivers, and the bird repelling means can transmit diverse audiovisual signals. A problem in the known systems is that a small number of the birds are not sufficiently frightened, and that other birds can be frightened such that their powers of orientation are reduced and they do not know in which direction to fly. Particularly at airports this can lead to potentially dangerous situations which can result in damage to engines, delays, and even serious accidents.
The invention has for its object an inexpensive and/or efficient system for averting birds which reduces the chance of damage, accidents and/or delays at an airport.
According to the invention the detection zones in a first group lie for this purpose closer to the runway (or the object) than the detection zones in a second group, wherein the bird repelling means of the detection zones of the first group are adapted to generate a repelling signal other than the bird repelling means in the detection zones of the second group. The detection zones within a group herein preferably extend substantially parallel adjacently of each other on either side of the runway. In this way the birds first receive a repelling signal with less impact as they approach the runway. The birds are hereby warned. If however they do not react to the first repelling signal and continue to fly on, they are given a second repelling signal with more impact shortly thereafter. The birds will hereby perceive the unpleasant repelling signals as having increasing impact, and they will decide to turn back to where they came from. The average distance between the centre of the zones in the first group and the central axis of the runway- is preferably 0 m to 400 m, and the average distance between the centre of the zones in the second group and the central axis of the runway is preferably 300 to 700 m. The bird repelling means are preferably adapted such that the transmitted repelling signals are directed away from the runway.
In a first preferred embodiment the bird repelling means are adapted such that the intensity of the repelling signal in the detection zones in the second group is lower than the intensity of the repelling signal in the detection zones in the first group. In a particular embodiment the detection zones herein extend along the runway in more than two groups, wherein the intensity of the repelling signal decreases the greater the distance of the groups from the runway.
In a second embodiment the repelling signal of the bird repelling means in the detection zones in the second group is a type of signal other than the repelling signal of the bird repelling means in the detection zones in the first group. The repelling signals can for instance comprise a sound signal, a light signal, a gas cloud and/or a liquid mist.
The features of the first and second embodiments can also be combined, i.e. the signal in the second group is of a different type (i.e. of a less severe type) and has a lower intensity, whereby an additionally effective system can be obtained.
At least one detection zone further preferably extends in front of at least one end side of the runway, more preferably a plurality of detection zones belonging to different groups. The other detection zones are preferably elongate and herein each extend parallel to the runway.
In the preferred embodiment the bird detecting means comprise radar means. A particularly suitable device which can be used for this purpose is the BirdDeter™ bird deterring system from Vigilance Technologies (www.birddeter.com.au). The technical operation of such a detection system is described in more detail in international patent application WO 95/08126. Alternatives to radar detection means can consist of, among others, microwave detectors, vibration detectors, sound detectors or cameras. The bird detectors preferably comprise pairs of" transmitters and receivers which are each placed at an outer end of each elongate detection zone. The length of the detection zones can herein be 200 m to 800 m. The transmitters in nearby detection zones are preferably set to different transmission frequencies in order to prevent mutual disruptions and interference.
An alternative detection system is for instance the Passive EO Radar - Perimeter Defense System from Magna BSP, wherein an area around one point is observed stereoscopically using a video camera, the images of which are analysed for movement. According to the invention the detection zones are in that case defined in the observed area by means of software.
The invention further relates to a system for averting birds from the vicinity of a runway at an airport, wherein the system comprises birds detecting means and bird repelling means coupled thereto, wherein the bird detecting means are adapted to detect the presence of birds in different detection zones in the vicinity of the runway and to activate subject thereto bird repelling means which are directed at the relevant detection zone.
The invention further relates to a method for averting birds in the vicinity of a runway at an airport, wherein bird detecting means are coupled to bird repelling means, wherein the bird detecting means detect the presence of birds in different detection zones in the vicinity of the runway and activate subject thereto bird repelling means which are directed at the relevant detection zone.
The invention will be further elucidated on the basis of an exemplary embodiment as shown in the figure, in which a schematic perspective view of a runway with a system for averting birds is shown. According to the figure the system consists of two groups of detection zones 11L..24R, which are disposed on both sides parallel to runway 1. In the figure the runway 1 is divided in the length by means of auxiliary lines into sections designating the length of the detection zones. The first group comprises detection zones 11L..14L and 11R..14R. The second group comprises detection zones 21L..24L and 21R..24R. The first group of detection zones 11L..14R is disposed at about 200 metres distance from the central axis of runway 1. The second group of detection zones 21L..24R is disposed at about 500 metres distance from the central axis of runway 1.
A radar transmitter 2 and radar receiver 3 are disposed at the outer ends of each detection zone HL - 24R. Radar systems from for instance Vigilance Technologies provide such a radar detection zone over a length of up to 600 metres, wherein radar transmitter 2 and radar receiver 3 are placed at a height of 6 metres. This involves radar detection with waves in the 2.4 GHZ band. Placed close to receiver 3 of a detection zone is a transmitter 2 of a nearby- detection zone of the same group, which transmits to radar receiver 3 at the other end of that detection zone. Chains of detection zones are set up in this manner. Because the frequencies of radar transmitters 2 are different in nearby detection zones, mutual disruption can be prevented.
The detection of a bird 5 in a detection zone is realized via analysis of the received radar signal on the basis of pattern recognition using software. If there is a recognition on the basis of set parameters in the software program, repelling unit 4 is then activated automatically within 1 to 2 seconds, either via a cable or radiographically. The arrow at each repelling unit indicates the direction in which repelling must take place; this is directed towards the approaching bird 5 and away from the runway, and covers at least the whole detection zone. Repelling unit 4 can consist of a directional loudspeaker which can reproduce amplified sounds stored in a playback module (comprising a chip and a D/A convertor) . The sound can be the sound of a rifle-shot followed by the sounds of a frightened bird 5.
Repelling units 4 in the first group of detection zones 11L..14R can reproduce a more intense sound than repelling units 4 in second group 21L..24R in that the volume is increased or in that more rifle-shots with cries of fear are reproduced. The signals can also be of a different nature, for instance a moving green laser light, such as the TOM500 from the French company LORD Ingenierie (www. lord-ing. com/fr/actuproduits . htm) .
In this set-up it is the intention that a bird which is detected in the second group of detection zones is averted and kept away from runway 1 by activation of a repelling unit 4. Should this not happen, and bird 5 still flies on in the direction of the runway, bird 5 can then be detected in the first group of detection zones and there averted by a repelling unit 4.
The choice of different successive repelling signals which can go off depending on the detection position of the detected bird 5 relative to runway 1 makes it possible to keep birds 5 away from runway 1 in sequence and automatically as they approach closer to runway 1. By successively increasing or making more negative the intensity of the negative stimulus for bird 5 or the quality of the stimulus for bird 5, the deterrence can thus increase the closer the bird approaches runway 1. The chance of a bird 5 not flying close to or over runway 1 can hereby be increased.
