Definitions

  • the invention relates to a method and a device for distance measurement between two route points or a route point and a rail vehicle.
  • the accuracy of distance measurements in the sense of displacement and speed determination is of fundamental importance for railway control and safety technology, since safety-relevant functions for train control and train control are implemented on this basis.
  • the most accurate distance and derived speed measurements are required for the calibration of speed sensors. Calibration is performed by comparing the sensor readings with a reference or a normal. From the deviation between the two values, a calibration value for the measured value correction of the velocity sensor is derived.
  • a regular calibration is in all odometric systems, eg. B. vehicle-side or trackside radar sensors required. So far, for calibration, ie as a reference or normal, various, especially working with diversified measuring principle, sensor systems used. Often used to Wegimpulsgeber based on the count of Radumcardoder. In general, the measurement uncertainty of the reference systems is problematic, with position encoders, for example due to the spin and sliding effect.
  • the invention has for its object to provide a method and an apparatus that allow a more reliable and accurate distance measurement.
  • the object is achieved in that between see the route points or the waypoint and the rail vehicle, the term of an RFID (radio frequency identification) signal is measured.
  • RFID radio frequency identification
  • a device for carrying out the method according to claim 4 has for this purpose an RFID transmitter / receiver assigned to a first route point and an RFID receiver / transmitter assigned to a second route point or an RFID receiver / transmitter assigned to the rail vehicle, and means for measuring the transit time of an RFID Signal between the first and the second waypoint or between the first waypoint and the rail vehicle.
  • the running time of the RFID signal which is a measure of the distance and its temporal change thus represents a distance and speed measure, can be conveniently set to the highest
  • the RFID signal can be transmitted bidirectionally or unidirectionally. In the latter arrangement, either the first waypoint is equipped with an RFID transmitter and the second waypoint or Rail vehicle with an RFID transmitter or vice versa. The positioning of the RFID components is easily possible and does not require precise alignment between transmitter and receiver.
  • the transit time of the RFID signal between locating reference points is measured.
  • RFID transmitters and receivers are particularly suited to be positioned exactly perpendicular over the two locating reference points, so that the distance can be measured with high precision over the signal propagation time.
  • the speed of the rail vehicle is determined as a function of the transit time of the RFID signal and used for the calibration of speed sensors, in particular Doppler radar sensors.
  • speed sensors in particular Doppler radar sensors.
  • the RFID measuring system works independently of spin and glide effects, which makes calibration more accurate.
  • FIG. 2 shows a system for calibrating speed sensors.
  • FIG. 1 shows three locating reference points in the form of Eurobalises 1, 2 and 3 whose distance is to be measured.
  • the euro rail 3 is assigned to an operating stop of a rail vehicle with respect to a platform 4 with platform screen doors 5.
  • a brake curve dependent on the actual speed is determined and monitored on the vehicle side.
  • an RFID transmitter and / or receiver 6 is arranged vertically above the Eurobalise 3, which is arranged with an RFID receiver and / or transmitter 7 vertically above the Eurobalise 1 - as shown - or perpendicular above the Eurobalise 2 ,
  • the transit time of a continuously transmitted RFID signal is measured and serves as a distance measure between the locating reference points.
  • Speed sensor Shown is a rail vehicle 8 with a vehicle device 9, which cooperates with a Doppler radar sensor 10 for speed determination.
  • an RFID transmitter / receiver 11 is at least temporarily attached to the front end of the rail vehicle 8, which cooperates with a trackside reference RFID transmitter / receiver 12. From the transit time of the RFID signal between the two RFID components 11 and 12, a very precise distance equivalent can be generated.
  • the results of the speed measurement by means of Doppler radar sensor 10 and by means of RFID signal are compared. The difference of the measurement results is converted into a calibration factor and ultimately used to calibrate the Doppler radar sensor 10.

Abstract

L'invention concerne un procédé et un dispositif pour mesurer la distance entre deux points d'une voie ou entre un point d'une voie et un véhicule ferroviaire (8). Selon l'invention, pour qu'une grande précision de mesure puisse être obtenue, le temps de propagation d'un signal RFID (d'identification par radiofréquence) est mesuré entre les points de la voie ou entre le point de la voie et le véhicule ferroviaire (8).
