Definitions

  • the present invention relates to a method for to allow braking and / or stopping of a moving vehicle on a railway type track.
  • beacons are arranged at known and fixed distances and emit a signal.
  • the vehicle detects using a antenna the passage above the first beacon and starts a stopwatch, which is stopped by the passage above a second tag. Knowing the distance between the two beacons and the time taken by the vehicle to travel this distance, we can easily deduce the speed of the vehicle. However, it should be noted that this is an average speed over the distance traveled between two beacons and not an instantaneous speed calculated in one point.
  • the distance between these tags can be modified by external factors such as conditions or the incorrect positioning of these beacons.
  • Document DE-A-2630970 describes a method of rail traffic monitoring which allows to transmit a command from a traffic light by through a transmission device to a monitoring device on the car conductive.
  • Ground equipment includes a transmitter which transmits coded information of a channel signal using a beacon of emission, while the equipment of board includes a receiver connected to at least one antenna reception, preferably fixed below the vehicle so as to correspond with the emission tag, as well as a computer for decoding and processing information received.
  • the installation also includes a means for coding channel signaling information, an active transmitter for frequency modulation of a field magnetic, a means of comparison to a threshold of amplitude of the magnetic field emitted and a means of controlling the frequency transmitted using the transmission beacon.
  • the means of comparison of the amplitude of the field magnetic emitted and frequency control means are connected to a signal control means security, which eventually allows you to take a floor safety action in case of failure.
  • the tag used is a smart tag that continuously emits a message that will be collected by the antenna on the vehicle and analyzed by this one.
  • Document DE-A-2648383 describes an installation for measuring the speed of a vehicle such as a automobile car by measuring a modification of induction created by a device in the form an induction loop placed in the ground when the vehicle enters its field of influence.
  • the present invention aims to propose a method which allows the braking and / or stopping of a moving vehicle on a railway type track, which does not require a complex installation and which allows precise measurement while by being free from external contingencies such as climatic conditions, as well as exact positioning beacons present on the track during interventions maintenance of these.
  • the present invention relates to a method intended for braking and / or stopping a vehicle traveling on a railway type track using a installation which includes on the one hand a ground equipment attached to the track, itself comprising minus a beacon of emission of a magnetic field, and other share on-board equipment comprising at least one antenna preferably fixed below the vehicle so that correspond with the emission tag.
  • the emission beacon emits a field frequency modulated magnetic transmitting indications coming from an encoder itself controlled for example by a traffic light.
  • the length of the tag is also calibrated.
  • the tag can optionally transmit this information under coded form in the message it transmits to the antenna present on the vehicle.
  • the entry and exit times of the magnetic field are not defined by the crossing of a fixed threshold value of it but by the fact that a certain percentage of the magnetic field is exceeded maximum received when passing over the tag corresponding.
  • this is carried out in two stages, i.e. on the one hand when the magnetic field is maximum, corresponding for example to the presence of bits at 1, and on the other hand when the magnetic field is minimum, corresponding for example to the presence of bits at 0.
  • the tag is mounted between the two rails of a track offset from the center line the way.
  • This tag is, according to an embodiment preferred, consisting of a single sufficiently rigid turn which forms a secondary winding of a transformer magnetic circuit in the primary circuit of which is injected the frequency modulated current.
  • the primary winding is mounted at the interior of the single turn on an axis perpendicular to the plan of the said turn which is fixed on the track by preferably via "S" shaped legs.
  • the receiving antenna mounted below the vehicle is preferably made up of two windings of which one is wound from the left and the other from the right.
  • the installation as shown in the figures 1 and 2 includes floor equipment (1) fixed on the track and possibly connected to a means of signaling or emission (2), and on the other hand a on-board equipment (3) housed in the connected vehicle to the brake system.
  • Figure 1 shows the first form of execution, in which a single tag (A) is used.
  • the function of the installation is simply to control the braking or possibly stopping the vehicle when the beacon sends a message stop.
  • FIG. 2 shows a second form of execution, in which another tag (B) plays the role speed control and is commonly called in English "speed trap".
  • the installation allows, from the passage of the vehicle on the first beacon (B), check the speed of it and possibly activate the braking circuit if this speed exceeds for example 5% the authorized speed.
  • each tag (including the beacon A), then makes it possible to carry out a speed control independent.
  • Accurate speed measurement when passing over a tag requires exact knowledge of the length of the beacon and instants of entry and exit of the field magnetic emitted by the beacon.
  • the length of the tag can for example be indicated in coded form in the message issued by this tag.
  • Determining entry and exit times of the magnetic field is much more delicate, because the nominal amplitude of the field received at the center of the beacon by the receiving antenna varies enormously depending on different factors, such as tension amplifier power supply to the ground, the distance separating from the beacon, the height of the air gap separating the beacon of the receiver antenna which itself varies in function of wheel and rail wear, lateral offset possible antenna - beacon in curves, etc.
  • the magnetic field received by the antenna is, according to a preferred embodiment, modulated by the message sent by the tag: even in the case of a frequency modulation transmission, limiting bandwidth required by compliance with legal standards transmits an amplitude modulation which is translated by the fact that the amplitude of the received signal, in a point along the tag, depends not only on the abscissa of this point relative to the center of the tag, but also, because the bit of the message received at this time is at (1) or at (0). This therefore leads to a variation of the abscissa of point of entry and exit of the magnetic field depending on the instantaneous conformation of the received message.
  • all of processing related to speed determination is performed twice: the maximum magnetic field received in this way that the relative moments of entry and exit, for example, at the presence of bits at (1) are first determined and a first speed is deduced therefrom; the magnetic field received as well as the entry and exit times related to the presence of bits at (0) are then determined and a second speed is deduced from it.
  • FIG. 3 shows more particularly a beacon used in track equipment.
  • This tag which must emit a calibrated magnetic field consists of a single stainless steel coil about 150 cm long and 30 cm wide, forming the secondary circuit of a magnetic circuit transformer in the primary circuit from which a modulated current is injected continuously. he it should be noted that the length of the coil is adapted to the duration of the message transmitted from the track to the train and to the maximum line speed.
  • the primary winding is advantageously mounted on the axis arranged inside the single turn, perpendicular to the plane thereof.
  • the single turn sufficiently rigid is mounted between the rails, provided two opposite legs in the shape of an "S".
  • the primary circuit is poured into a housing fixed below of the mounting bracket.
  • a control circuit sends the voltage level for controlling a relay called KTBL with output fault / safety logic if a magnetic field sufficient and at correct frequency is generated by the turn.
  • This KTBL relay can also be used for immediately detect whether a defect in the tag or in the encoder occurs.
  • Information transmitted to the vehicle by the beacon signaling is generated using an encoder arranged near the beacon, this encoder being connected to the signaling via a current transformer and giving possibly information regarding the appearance of the signage.
  • Interface with the signaling system can also be achieved by using a bond of the encoder either using signaling logic fault / safety relay type, either using a module "Solid State Trackside Functional Module” (TFM) Interlocking "(SSI).
  • Figure 4 shows the on-board equipment.
  • This on-board equipment includes at least one receiving antenna (5) outer fixed below the vehicle (3) and offset relative to the axis of the track seen in the direction of travel.
  • the receiving antenna advantageously consists of a left-hand winding and one winding winding straight mounted one inside the other on the same axis.
  • this layout allows in particular to reject emission beacons corresponding to the direction of traffic reverse or to parallel tracks. This particular arrangement antenna therefore allows safe selection the appropriate emission beacon. Indeed, magnetic fluxes perceived by the left and right windings of an antenna are in phase agreement when the transmission beacon correct pass below the antenna.
  • a single antenna is sufficient on board the vehicle and will preferably be installed under the drive car.
  • an antenna is installed at each end of the train, each antenna being then associated with a driving direction.
  • a transmission is carried out by frequency modulation of the magnetic field radiated by the beacon tuned to 100 KHz.
