Definitions

  • the invention relates to a method for checking a truck, in which the load compartment of the truck is X-rayed while the truck is moved past the X-ray source, and an apparatus for carrying out the method.
  • a typical length of the cab is assumed, and X-ray fluoroscopy starts at a fixed distance from the tip of the truck. This method involves the risk that a part of the hold is not illuminated and thus not checked. If the driver's cab is assessed as too short, this may result in unintentional irradiation of the people in the driver's cab.
  • a method and a device of the generic type are known from DE 101 22 279 A1.
  • This document describes an X-ray system with a diaphragm for the X-rays, whose opening and closing is controlled by a bar code reader.
  • a barcode is attached to the load compartment of each truck to be tested, which triggers the beginning of the X-ray examination, by causing the opening of the aperture. Since barcodes must be attached to each truck as markings, this procedure is very time consuming.
  • the invention is therefore an object of the invention to improve a method of the generic type so that an accurate and rapid distinction between the not to be screened cab and to be screened load compartment of a truck.
  • This object is achieved according to the invention in that for determining the switch-on of the X-ray source of the truck is irradiated on one side with electromagnetic radiation, in particular laser beams, a wavelength between 200 nm and 3000 nm and the radiation reflected at the transition between the driver's cab and the load compartment is measured.
  • the invention makes use of the fact that the driver's cab and the loading compartment of a truck are usually limited by metal walls.
  • aerodynamic fairings at the transition between the driver's cab and the cargo area usually consist of plastic-based materials such as glass fiber reinforced plastics (GRP), whose reflection behavior is different for the electromagnetic radiation used.
  • GFP glass fiber reinforced plastics
  • Rotary laser scanners in which the measuring sensors are integrated in the housing of the laser source have proven particularly suitable.
  • the speed of a truck moving past is determined by means of an additional radar sensor.
  • an additional radar sensor In this way, distortions resulting from speed fluctuations can be corrected when determining the switch-on time.
  • the invention will be explained in more detail with reference to an embodiment shown in simplified form. 1 shows a rough schematic side view of a
  • FIG. 1 shows a lorry which contains a loading space 1, a driver's cab 2 and a transition area 3 between the driver's cab 2 and the loading space 1.
  • the transition region 2 is aerodynamically lined to reduce drag.
  • the aerodynamic panels are made of plastic-based materials, such as glass fiber reinforced plastic (GRP), which are optically opaque to electromagnetic radiation in the visible range.
  • GRP glass fiber reinforced plastic
  • the X-ray inspection system not shown in the drawing, contains an X-ray source and a detector arrangement, which is aligned with the X-ray source, and between which there is a route for the truck.
  • the X-ray source emit X-rays with a sufficiently high energy of more than 1 MeV.
  • the truck drives automatically through the X-ray inspection.
  • the driver thus drives the truck on the route between the stationary X-ray source and the stationary detector assembly past them.
  • the X-ray source it is necessary for the X-ray source to be switched off while the driver's cab is passing by. Immediately after the cab passes the beam area, the X-ray source must be turned on to check the beginning of the hold.
  • the X-ray source of the truck is irradiated on one side with electromagnetic radiation, in particular laser beams, a wavelength between 200 nm and 3000 nm, until the transition region between the cab and the cargo space is detected and thus has safely passed the cab.
  • electromagnetic radiation in particular laser beams
  • the radiation reflected by the truck is measured at least until the transition between the driver's cab and the load compartment.
  • laser sources laser diodes are advantageously used.
  • rotary laser scanners are placed on one side of the guideway that extends between the x-ray source and the associated detector array.
  • the measuring sensors are integrated in the housing of the laser source.
  • Rotary laser scanners with an IR laser (880 nm-950 nm, for example 905 nm), an angular range of 270 degrees with an angular resolution of 0.5 degrees and a scanning frequency of 50 Hz, which are at a distance between 0 and 0, have proven particularly suitable , 5 m and 20 m to the truck.
  • a rotary laser scanner 4 with a transmitting and receiving unit is arranged on one side of the travel path.
  • the laser scanner 4 is arranged along the route so that it is located at the beginning of the measurement in the region of the beginning of the driver's cab 2. Its lateral distance from the route is about 3 m. With this arrangement, the length of the cab 2, the length of a container as a cargo space 1, and the length of the entire vehicle can be determined.
  • the measured reflection power is high as long as radiation is reflected from the metallic cab 2 or a metallic cargo space 1 such as a container.
  • the measured reflection power drops markedly.
  • the plastic-based casing of the truck in the transition region 3 allows the predominant portion of the radiation to pass through without reflecting it.
  • the received power drops significantly, the X-ray radiation can be switched on, since the driver's cab 2 is no longer in the beam path of the X-radiation.
  • an additional radar sensor is preferably arranged in the X-ray inspection system, which determines the speed of the truck moving past.

Abstract

Dans l'état de la technique figurent des procédés pour contrôler l'espace de chargement (1) d'un poids lourd, le poids lourd passant au niveau d'une source de rayons X qui est activée au cours du passage de l'espace de chargement (1) et qui est désactivée au cours du passage de la cabine de conduite (3). Selon l'invention, pour permettre la détermination de l'instant d'activation de la source de rayons X, le poids lourd est exposé sur un côté à un rayonnement électromagnétique, notamment des rayons laser de longueur d'onde comprise entre 200 nm et 3000 nm, et le rayonnement qui est réfléchi au niveau de la transition (3) entre la cabine de conduite (2) et l'espace de chargement (1), est mesuré pour permettre la détermination de l'instant d'activation de la source de rayons X.
