Definitions

  • the invention relates to a method for speed monitoring of rail vehicles and a related device.
  • Speed monitoring devices are usually used to control the speed of the rail vehicle to a desired value and / or to initiate emergency braking in case of exceeding a maximum allowable speed.
  • the maximum permissible speeds are line-specific maximum speeds, for example, in the case of downhill gradients, track curves with small radii, butt tracks or sweeping systems, and on routes with shortened slip paths.
  • two sub-functions are to be realized, namely measurement and evaluation of the approach speed of the rail vehicle to a trackside device and at excessive speed transmission of a brake command to the rail vehicle.
  • FIG. 1 illustrates a typical configuration of known type for solving this problem.
  • the trackside device consists of a driving lock 1, for example, based on inductively acting coupling coils or magnetically, electro-mechanically or mechanically acting contacts, and an upstream measuring section 2 with two measuring points 3 and 4, for example, on the basis of inductively acting wheel sensors.
  • the rail vehicle 5 is equipped with a device 6, which detects its activation state or deactivation state when driving over the track-side driving lock 1.
  • the driving lock 1 In the basic position, the driving lock 1 is always activated and thus leads to forced braking. tion of the overlying rail vehicle.
  • the measurement and evaluation of the speed is based on the specified distance between the two measuring points 3 and 4 and the determined time interval of the pulses registered by the measuring points 3 and 4.
  • the determined speed is compared with the maximum permissible line speed, wherein the driving lock 1 is only deactivated when the determined speed is less than or equal to the maximum speed.
  • the driving lock 1 remains active and thus leads in cooperation with the rail vehicle-side device 6 for emergency braking.
  • a disadvantage of this known speed measuring device is in addition to the considerable effort for the sensor, especially the punctual measuring principle.
  • the invention has for its object to provide a method and an apparatus that allow a simpler and thereby continuous speed measurement.
  • the object is achieved in that the rail vehicle emits a signal whose term is evaluated on the track side with respect to the speed and that the evaluated signal is transmitted back to the rail vehicle.
  • a device for carrying out the method has for this purpose a vehicle device with a transmitter / receiver module and a trackside device with a receiver / transmitter module, wherein the trackside device comprises an evaluation unit for speed evaluation of one of the transmitter / receiver module of Vehicle device has received signal.
  • speed monitoring is possible even without the use of the conventional, expensive, trackside sensors.
  • Stationary measuring points and the associated wiring are eliminated. Due to the possibility of bidirectional signal transmission, a driving lock with associated cabling is unnecessary. There are much less trackside components that are particularly susceptible to wear due to mechanical, climatic and biological / chemical environmental conditions required.
  • an RFID radio frequency identification signal is radiated, evaluated and retransmitted.
  • the transit time of the RFID signal which is a measure of the distance and its temporal change thus a speed measure, can be conveniently determined with highest accuracy.
  • both a continuous speed measurement and a continuous retransmission of a response signal to the monitored rail vehicle is possible. It is also advantageous that an RFID vehicle device in addition to the regular train operation for
  • Special trips, z. B. not regularly on the routes of running construction vehicles, can be used.
  • a portable version of the vehicle unit entrainment is also possible by small units. Due to the portability of the vehicle device, it is also possible to transfer it before entering the section to be monitored for exceeding the speed limit and to withdraw or deactivate it at the end of this section of the route.
  • a use as a fallback level for main lines is conceivable or even temporary, for example, construction-related track closures, making only a one-track ride is possible.
  • the trackside device can be made variable in location. The positioning of the vehicle side and Trackside RFID components do not require precise alignment between an RFID transmitter / receiver module on the rail vehicle and an RFID receiver / transmitter module on the track.
  • its robustness and small size are advantageous in the speed measurement by means of RFID components, as a result of which a temporary use determined by the requirement is made considerably easier.
  • a signal triggering emergency braking is transmitted back to the rail vehicle.
  • emergency braking is required only at excessive speed, so that the signal retransmission can be dispensed with if the speed is adjusted.
  • Figure 1 is a speed monitoring device of known type
  • FIG. 2 shows a speed monitoring device according to the invention.
  • FIG. 2 the components which are identical for the known speed monitoring device, which is illustrated in FIG. 1 and explained above, are identified by the same reference numerals. It can be seen that a measuring distance 2 - FIG. 1 - installed by fixed measuring points 3 and 4 - FIG. 1 - which is wired to a driving lock 1 - FIG. 1 - is dispensed with.
  • a vehicle device 7 is provided with a transmitter / receiver module of the transponder / reader technology, the RFID signals 8 which is received by a trackside device 9 with a transponder / reader technology receiver / transmitter module and evaluated with regard to vehicle speed. The evaluation takes place in such a way that a speed derived from the transit time of the signals 8 is compared with a maximum permissible speed.
  • An evaluation unit 10 of the trackside device 9 is used for this purpose. If the maximum permissible speed is exceeded, an RFID response signal 11 is generated, which contains a command for triggering an emergency braking and transmitted to the vehicle device 7.
  • the measurement of the current speed is carried out in this way not only punctually - as in the speed monitoring device according to Figure 1 - but continuously.
  • the transmission of a command for emergency braking to the rail vehicle 5 is carried out continuously and not only when crossing a driving lock 1 - Figure 1 -. This results in addition to a simplification and reduction of the number of system components and increased reliability of the overall system for speed monitoring.
