Definitions

  • the present invention relates to surveillance of zones where, for ex ⁇ ample, aeroplanes are moving, preferably by means of laser radar or corresponding means to inform a control station or an operator about what is happening in the surveyed zone and/or to give information to an automatical control or docking system.
  • Aeroplanes moving at airports can find a wrong way, resulting in seri ⁇ ous consequences.
  • a method according to the present inven ⁇ tion it is possible to define the type and the position of aeroplanes at a distance and automatically, said aeroplanes being located in front of a scanner. By comparing this with what should be there, an alarm can be transmitted at an error situation.
  • the object of the present invention is to identify and permit an auto ⁇ matical supervision of how an aeroplane is directed, and also to be able to be used to determine a required path for its motion.
  • a scanner preferably of the laser radar type with a measuring beam which is sweepable over the zone, is brought measure different parameters in the surrounding and give information to a supervising station or an operator about what is happening in the surveyed zone or to give information to an automati ⁇ cal control or docking system.
  • the measuring beam of the scanner also be used to send information to receivers that are fixed or movably arranged in the nearness of the detection device, or to let its own receiver be used to receive information from other transmitters which are fixed or movably arranged.
  • the method according to the invention can be used to let the measur ⁇ ing beam sweep along the object present in the measuring zone and, through its shape, define if it is an aeroplane, and, by regarding dis ⁇ tance variations and shapes, decide how the latter is oriented, in what direction its nose is pointing, what type of aeroplane it is, distinguish it from similar models, and to have a possibility to compare the detected information with accessible information about the aeroplane which is supposed to be at the relevant place, and at an excessive signature difference, transmit a signal and then, possibly, relate this to a co ⁇ ordinate or matrix system.
  • a preferable embodiment of the invention is to let the measuring beam sweep across the undercarriage of the aeroplane and thereby define the position of the contact points of the undercarriage and the ground, and from that compute in what direction the nose of the aeroplane is pointing, as well as identify the aeroplane type from the positions of the undercarriages in relation to each other.
  • a way of simplifying the determination of the identity and position of the aeroplane is to provide every plane with a barcode arranged at the aeroplane in the shape of lines or surfaces of alternating high and low reflecting structure and giving strong signal replies as they are brought to be red by the scanner. This can be further amplified as said high reflecting surfaces are provided with retro-reflecting material or colour.
  • Another method is to let the scanner, with a narrow measure lobe, detect an aeroplane nose and thereby guide the measuring beam to fixed positions according to a fixed or variable matrix pattern which is single or double axled and search the shortest distance.
  • a problem during trailing and backing of aeroplane is that the nose wheel can be hurt at an excessive turn ⁇ ing.
  • the present invention can inhibit this by seeing to that said infor- mation is brought to guide aeroplanes during trailing and backing in such a way that a desired path is followed and that the motion is stopped at too large deviation from desired position, and that the nose wheel is correctly guided.
  • a way of increasing the precision is to let the scanner compute as well as detect known reference points along the motion and correlate this information with set values, to keep an eye on a position of an aero ⁇ plane along a known path, and that said information gives rise to syn ⁇ chronising or correcting pulses which are permitted to effect the guid ⁇ ing of the aeroplane.
  • Another possibility of the present invention is to decide the heights over the ground of the aeroplane body to estimate the downloading, and to let this information guide the docking ramp to correct height before the plane is in its final position.
  • One of the objects of the invention is to let the scanner detect if per ⁇ sons, ramps etc. are in immediate nearness of the vehicle and thereby transmit a signal.
  • the detecting beam of the scanner have a given polarisation, and when the scanner detects the polarisation de- viation of the reflected beaming in time and room resolution, let the information indicate possible existence of ice at the surface at which the reflection takes place.
  • a way of being spared from making the system unnecessarily data technically complicated is to let the scanner be movably arranged, to make it movable between different positions to obtain a position in relation to the plane which is as good as possible from a measuring point of view.
  • the presentation of the information from the system according to the present invention during aeroplane docking can take place on a screen-like display unit where the pilot gets information about his position as to longitudinal and lateral position, and can simultaneously also be shown at some other place, for example in the control tower.
  • the measuring beam and receiver lobe of the scanner are arranged to be swept in one or two dimensions by means of mirrors arranged at disk-stepping motors or other stepping motors with short reaction time and high torque and, if sweeping with mirrors takes place in just one dimension, let the scanner be pivotably arranged.
  • Fig 1 shows how a zone is scanned according to the invention
  • Fig 2 shows how a zone with an incoming aeroplane is scanned according to the invention
  • Fig 3 shows how a device accord ⁇ ing to the invention places obtained information in a system of co ⁇ ordinates
  • Fig 4 shows how a plane is scanned according to the invention.
  • Fig 1 it is shown how, according to the invention, an area is scanned by means of a scanner A with a measuring beam MS, and the shape of an object O is detected.
  • the 3-dimensional extension thereof is characteristical and is determined as to shape and position in the room with reference to the system of co-ordinates with the axles X, Y in the lower half of the figure, where MF shows how the scanner has interpreted the shape of the object in one plane. The measurement is then done in several planes.
  • a scanner A is shown as it sweeps in a height plane SL to ⁇ wards an aeroplane obliquely from in front of it.
  • the type of the plane as well as its motion direction can be determined. Complementing sweeping towards the nose portion gives the system according to the invention further information before the docking.
  • Fig 3 information is shown from the situation in Fig 2, put into a system of co-ordinates X, Y. There the co-ordinates of the undercar ⁇ riages P1 , P2 and P3 are indicated. The sweeping sector of the meas- uring beam MS is also shown.
  • Fig 4 it is shown from above how the scanner A has registered an aeroplane in its measuring lobe. Within the angle segment KZ the aeroplane body is detected 3-dimensionally. From this information the type of plane as well as the position of the plane and its instantaneous travelling direction FR can be determined.

Abstract

L'invention porte sur un procédé de surveillance d'aires où évoluent principalement des avions selon lequel un système de balayage (A), de préférence du type radar laser, est amené à fournir des informations à un système automatique de contrôle ou de stationnement. Le système de balayage fixe ou mobile en trois dimensions crée une image de l'aire située devant lui où se trouve un avion immobile ou en mouvement en se verrouillant sur un point défini de l'aire et en construisant des images informatives en utilisant ledit point comme référence. Par ailleurs, il effectue d'une part une comparaison continue avec d'autres détails caractéristiques des avions et objets environnants, puis d'autre part une comparaison de ces derniers avec des images fixées dans une mémoire électronique présentant la manière dont le signal de balayage devrait apparaître pour l'aire en question pour différentes dispositions de véhicules et différents types d'avions afin de déterminer l'orientation de l'avion et son type et d'émettre des signaux d'alarme et/ou de commande. Il est également possible de détecter en même temps la formation de glace sur les avions par observation des variations de polarité dans les réflexions.
