Definitions

  • the present invention relates to a method intended for measuring the speed of a vehicle running on a railway type track.
  • the present invention also relates to the installation intended for the implementation of this process.
  • beacons along railroad tracks in order to perform a measurement of the speed of the vehicle traveling on these tracks.
  • beacons which are arranged at known and fixed distances emit a signal.
  • the vehicle passing near this tag detects using an antenna the passage above the first tag and performs a time measurement until the passage of the second beacon.
  • the tags are placed at relatively large distances, and it essentially to measure average speeds over the distance travelled.
  • An electrical joint is consisting of two chord blocks used for coupling energy of the sections of track adjacent to each block okay and the short track distance between these two chord blocks (15 to 30 meters).
  • first chord block serves as a transmitter at a frequency given while the second chord block serves as a receiver at another frequency.
  • the functions of the electrical seal are on the one hand to prevent the propagation of the signal of a track circuit to the adjacent track circuit and other part of coupling the transmitter and the receiver with the way.
  • the present invention aims to provide a solution that can offer the maximum guarantees of safety in the railway sense of the term to the extent of speed of a vehicle moving on a type track rail.
  • the present invention aims more particularly to propose a process which allows a estimate of average speed independently causes of errors due for example to skating and the axle clutch, and which is based on the detection the passage of a train of joints separating the different track circuits.
  • the present invention aims to provide a system that can get rid of tag placement on along the tracks.
  • the present invention aims to use already present equipment which allow the location of the train and which are made up by track circuits with electrical seals.
  • the present invention relates to a method of measuring the speed of a vehicle equipped with a antenna and traveling on a track with two rails in the form of sections of track called "cantonments" separated by electrical seals, each electrical joint consisting of two tuning blocks and the predetermined section of track located between them, each of the tuning blocks allowing energy coupling for the adjacent section of track serving as a block, characterized in that at least two are detected current or voltage discontinuities of the signal seen by an antenna present in the vehicle traveling on the track near the regions of the first and second chord blocks of the same electrical joint, in order to measure the speed of the vehicle traveling on the track.
  • the first discontinuity is obtained during passage of the axle to the right of the first block of agreement for the frequency of this first chord block.
  • the second discontinuity is obtained in exerting an electrical action at the frequency of the first chord block.
  • This second discontinuity is obtained by creating an electric or magnetic field in the region of second chord block.
  • This electric or magnetic field is generated by a current proportional to the current emitted by the voltage injected at the first chord block. This field is generated directly by the current emitted by said voltage.
  • the action electric is a voltage injected in series with the voltage at the second frequency of the second chord block. This voltage injected in series is proportional to that which is injected into the first chord block.
  • the action electric is the injection of a current into a generator of voltage present in the second chord block, this current traversing a loop arranged between the rails, said current being proportional to the current emitted by the voltage injected into the first chord block.
  • the signal detected by the antenna located on board the vehicle traveling on the track is filtered at the frequency of the voltage injected at the first tuning block.
  • the present invention also relates to an installation for implementing the process such as previously described, in which the path is organized in the form of cantonments separated by joints electrical, each electrical joint consisting of at least minus two chord blocks and the short track section located between them.
  • This installation includes means to generate at least two discontinuities in current or in voltage in the signal seen by the antenna present in the vehicle traveling on the track near the regions of first and second chord blocks of the same joint electric.
  • An electrical seal as shown in Figure 1 consists of a first TU.F1 chord block located a first side (left), which will serve as a transmitter in view to generate a voltage in the channel at the frequency F1 and allows the energy coupling of this first side (left) of the lane adjacent to the chord block.
  • a second block agree TU.F3, placed at a distance of 15 to 30 meters, allows the energy coupling of the other part of the track (right) adjacent to this chord block.
  • This second block agree serves as a receiver for a frequency F3. he could possibly also be a transmitter which would generate a voltage at frequency F3.
  • Figure 2 shows a track circuit comprising several sections of track organized in cantonments and separated by electrical seals each consisting of two chord blocks coupled two to of them.
  • F1 the two tuning blocks TU.F1 and TU.F1 'are equivalent to a capacity which achieves track section agreement (block 1) included between these two blocks, while the two chord blocks TU.F3 and TU.F3 'are equivalent to short circuits to this same frequency (F1).
  • block 1 the two tuning blocks TU.F1 and TU.F1 'are equivalent to a capacity which achieves track section agreement (block 1) included between these two blocks, while the two chord blocks TU.F3 and TU.F3 'are equivalent to short circuits to this same frequency (F1).
  • F3 the function of the chord blocks is then reversed.
  • the passing axle 3 creates a shunt or short circuit between rails 1 and 2. More precisely, the behavior of the current I generated at frequency F1 and present in the rail 1 in front of axle 3 is modified.
  • the present invention consists in creating a second 8U discontinuity near the second block agree TU.F3 and use these two discontinuities occurring at a known distance in order to be able to calculate the average train speed between the two positions where produce said discontinuities.
  • a loop 4 between rails 1 and 2 near the TU.F3 block receiver component and equivalent to a short circuit to the frequency F3.
  • This loop 4 is supplied by a current at the frequency F1 which is preferably proportional to the current of block TU.F1. It is preferably connected in series with this block.
  • the field magnetic generated by loop 4 creates the second discontinuity 8 necessary for the implementation of the process according to the present invention.
  • the TU.F3 block is equivalent to a short circuit for the frequency F1.
  • the generator 5 is preferably supplied from the power supply of the TU.F1 block.
  • a current generator 6 is connected in parallel to the terminals of the TU.F3 block.
  • the flow thus generated traverses the loop 9 arranged between the two rails 1 and 2, thereby creating a detectable magnetic field at this place.
  • the generator 6 at the frequency F1 is advantageously arranged in series with the TU.F1 block and creates thus the second discontinuity sought 8.
  • FIG. 9 shows the current I in depending on the distance traveled on the rails in positioning the block TU.F1 creating the first discontinuity at -18 m and the TU.F3 block creating the second discontinuity at point 0.
  • the cost of installing the device additional is relatively reduced and thus allows obtain a relatively precise measurement of the speed of the train running on a track. Furthermore, the measurement of this speed remains independent of a precise positioning of tags, for example, whose displacement could intervene in the event of track maintenance interventions, climatic phenomena, wheel engagement, etc.
