Definitions

  • a system for locating a transponder that is moves along a track with a certain width.
  • Such a system is more particularly intended for an installation of multi-way highway toll including a camera suppression system with automatic identification of fraudulent vehicles by image capture of plates of registration of these fraudulent vehicles.
  • vehicles using the motorway network are each equipped with a transponder (generally placed behind the windshield) likely to communicate with beacons mounted on a gantry overhanging the lane at a toll section.
  • Each transponder may include a prepayment card which is debited when transponder under the gantry following a transaction between the transponder and a management center connected to the beacons.
  • EP 0 627 718 A1 shows the characteristics of the preamble of claim 1.
  • it is known use directional antennas powered in phase.
  • the object of the invention is to propose a system for locating laterally a transponder which passes under an electronic toll gate, that is to say to determine its position relative to a lateral side of the track.
  • Figure 1 very schematically shows an electronic toll system multi-lane motorway using a location system according to the invention.
  • Figure 2 illustrates very schematically the principle of localization a transponder using beacons according to the invention.
  • Figure 3 illustrates the association of portions of track width with the tags.
  • a multi-way electronic toll system motorway includes a microwave communication system to base of B tags and T transponders able to communicate remotely sets.
  • Beacons B are arranged on a gantry 1 overhanging the tracks parallels on which vehicles move. Thereafter we will refer only one track to designate the parallel tracks under gantry 1.
  • Each vehicle using the toll lane must be equipped with a transponder T which is generally fixed behind the windshield of the vehicle as illustrated in figure 1.
  • Each T transponder includes a transmitter / receiver and a electronic management of an electronic prepayment card which debits in the card a certain amount following a transaction between a connected management center to the transmitter / receiver beacons and the transponder which passes under the gantry.
  • the installation also includes an image capture system including cameras such as 2 placed upstream of gantry 1 in the direction of moving vehicles to photograph the back plates here of registration of vehicles passing under the gantry to carry out a crackdown on fraudulent vehicles. Other cameras may be provided for photograph the vehicle registration plates.
  • Infrared, laser or similar detectors such as 3 are arranged on gantry 1 to detect the passage of vehicles and locate them. More particularly these detectors 3 are divided into several curtains of detectors (three curtains in Figure 1) which extend transversely to the track which allows them to be located both transversely to the track and longitudinally with respect to the track.
  • the lateral location system of a T or more transponder T transponders arriving directly under gantry 1 therefore uses communication between the beacons and the transponder (s).
  • each beacon B has a communication zone which in space is substantially ovoid and which in relation to the ground has the shape of an ellipse S.
  • FIG. 2 shows six beacons B1 to B6 which are distributed over the width l v of the channel 4.
  • the number of beacons is here purely illustrative. Each beacon is capable of communicating with a transponder which moves in its communication area.
  • the communication areas of the beacons B1 to B6 are represented by ellipses S1 to S6. It can be seen in FIG. 2 that the communication zones of the beacons have a small width lB smaller on the ground than the width l v of the channel 4.
  • the distribution of tags B1 to B6 transversely to. the channel 4 is such that the communication zones S1 to S6 respectively of the beacons B1 to B6 overlap two by two and cover the entire width l v of the channel 4.
  • a control means U which is connected to the tags B1 to B6 acts cyclically on these beacons in order to make them emit signals in order to establish a communication with a transponder which will pass under gantry 1, that is to say which will cross at least one of the communication zones S1 to S6.
  • the way control is arranged to detect and identify the tags having established the communication with the transponder and to associate the tag or tags detected with one of the lateral portions P1 to P6 of channel 4.
  • the tags B4 and B5 have established a communication with a transponder, this is located at the intersection of the communication zones S4 and S5, i.e. in the P4 / 5 portion of width of channel 4.
  • This control means U can be programmed to restore a signature in the form of a binary word comprising as many bits as lateral portions defined for the channel, a bit at 1 in this word indicating by example, the donation portion where the transponder is located.
  • the control means U is adapted to transmit a signal first by the tags B1, B3, B5 and then by the tags B2, B4 and B6 (or vice versa) so as to avoid interference problems between tags adjacent. It is understood that this temporal multiplexing of the emission of the beacons can be changed.
  • control means U can be adapted to perform a transponder positioning control by selectively reactivating the two beacons that established communication with the transponder by making them re-issue signals.
  • Tags B can also be used to determine the position longitudinal of a transponder on the track if the control means U is suitable to date the lateral positioning signatures.
