Definitions

  • the invention relates to a method and a device for determining the Distance between a measuring system and a measuring system adjacent and in the same track located railway vehicle.
  • Another method according to the prior art for determining a Position of a railway vehicle are train detection systems.
  • axle counter In track detection systems by axle counter is located at the beginning and on At the end of the section of the track to be monitored a pulser, each one individual axle of a vehicle registered. Additionally it is registered in which direction the vehicle is moving. With unequal number of determined axles of the axle counters at the beginning and at the end of the track an occupied track and thus the position of the vehicle reported.
  • distance measurement is that the distance between two vehicles only in units each of the length of a train detection system and thus only very can be determined roughly or at an unreasonably high cost.
  • track sections of a length of less than 30 m in length are not possible because cars with a large center distance do not have a section may bridge.
  • these are fixed Devices for distance measurement, not directly on a moving Railway vehicle can be attached.
  • An inventive method is based on a dependence of electrical Properties of one of the tracks of the track and the first axis of the Measuring system bearing and the last axis of the adjacent railway vehicle formed conductor loop from the distance of the relevant Axes.
  • the measuring system will be abbreviated Railway vehicle as a locomotive and the adjacent and in the same track located railway vehicle referred to as a target car.
  • the two rails of a track of one accepted as isolable Superstructures are from both a first axis of the locomotive and shorted to a last axle of the target car. These elements form a rectangular electrical conductor loop, the width of the track of the Track and its length the distance between the two axes equivalent.
  • the distance of the vehicles results from the determined distance the two axes from each other minus a known distance one Leading edge of the buffers of the locomotive from the first axis, the so-called Overhang, as well as an unknown overhang of the destination car.
  • the electrical properties of this electrical conductor loop are a measure for the desired distance of the vehicles.
  • the coupling coil To capture these electrical properties of the locomotive is a Coupling coil between the first axis and a leading edge of a Buffer carrier arranged, the coupling coil for reasons of profile freedom in particular has a height of about 150 mm above rail top.
  • the primary side of this transformer is from the Coupling coil, the secondary side of the rectangular electric Conductor loop formed.
  • a current in the coupling coil is thus one attributed to magnetic flux, due to the flux linkage also by the conductor loop formed from the superstructure and axes occurs.
  • the derivation of the measured value from the properties of the coupling coil takes place according to the underlying conductor loop, and thus is particular dependent on a frequency Z of a fed into the coupling coil Test signal.
  • the measuring arrangement is seen from terminals of the coupling coil as a process with concentrated parameters.
  • the determination of L M is carried out from a measurement at the terminals either directly as analogue value by cleverly choosing the measuring frequency, calculating the impedance at the terminals according to the equivalent circuit diagram and resolving it to L M , or alternatively using empirically determined, and then in tables stored comparison values.
  • L M O 2 ,O, 3O 2 ...
  • L M O 4 . 3O 4 ...
  • the specified operational requirements are met without a undue influence by the railway-specific environmental influences. These are in particular weather influences such as rain, snow, fog, and Frost as well as shocks or dirt.
  • the at frequencies of 50 Hz and 16.7 Hz send information signals and receive.
  • the coupling coil includes a plurality of separate windings, so that supply and measuring signal can be separated. This can be the Transmitting coil for the requirements of the feed circuit and the receiving coil be optimally optimized for the requirements of the evaluation circuit.
  • the method by means of a stationary switching device switched on. This is required when the inbound meal at downhill turnout area of the retracting begins, and this Switch area can not be isolated in accordance with the system. In this Turnout area must axle circling lead the locomotive. In the case, that a target car immediately behind the stationary switching device axle counting circuits must be stationary up to the place of location Secure switching device plus a braking distance. Alternatively, after Claim 5, the locomotive, the stationary switching device with less Speed, a so-called crawl run over. Can in concrete If the points areas are also isolated in accordance with the system, this works Measuring system also over points, and the approach trip can from the Reversing nozzles are regulated with the described system.
  • two rails 1, 2 of a superstructure assumed to be capable of being insulated are short-circuited both by a first axle 3 of a locomotive 6 and by a last axle 4 of a destination vehicle.
  • These elements form a rectangular conductor loop whose width corresponds to the gauge of the track, and whose length is from the known overhang 8 of the locomotive, the unknown overhang 9 of the target car, which in particular has a length of about 1.5 m to 4.1 m , And, the prevailing in the state of interest, distance of the vehicles composed. Consequently, the electrical properties of this conductor loop are a measure of the sought distance of the vehicles.
  • a coupling coil 5 is used, which at the Locomotive 6 between the first axle 3 and front edge buffer pile 11 in a height of about 150 mm above rail level is arranged.
  • the Current in the coupling coil 5 is assigned to a magnetic flux, which also passes through the conductor loop formed from the superstructure and axles.
  • the measuring arrangement is viewed from the terminals of the coupling coil shown equivalent circuit diagram (as a process with concentrated parameters).
  • G ' is the specific conductivity of the superstructure, KL1 and KL2 terminals of the coupling coil and Ls , Lq and Ü replica of the coupling coil as a scattering transformer.
  • the determination of L M is read from a measurement at the terminals KL1 and KL2 either directly as an analog value by the measurement frequency is selected clever, the impedance is calculated at the terminals according to equivalent circuit diagram and resolved to L M. Alternatively, the determination of L M is performed on the basis of empirically determined comparison values stored in tables.
