Definitions

  • the invention relates to a circuit for generating a presence signal according to the preamble of claim 1
  • This circuit is known, for example, from the published documents 41 23 837 (TiG 9001), 43 25 406 (TiG 9201) and 44 21 327 (TiG 9301).
  • the sensor belonging to the circuit is mounted on the rail in the magnetic area of influence of the wheels passing over and emits an electrical output signal when a wheel is passed over.
  • the output signals of several such sensors which are arranged on both sides of a road crossing the rail path, can be used to switch the monitoring signals of the level crossing (OS 44 21 327).
  • the output signals of the sensors are reliably recognized, so that on the one hand the warning is given when a railway vehicle is approaching but on the other hand unnecessary occupancy and blocking of the transition is avoided.
  • OS 44 21 327 two sensors, each provided as double-rail switches, are provided in front of and behind the intersection. Their output signals are converted into square wave signals (switching signals). Assuming one and the same direction of travel, the rising edge of such a square-wave signal causes a counting pulse to be read into the memory and the falling edge to read out a counting pulse from the memory. The problem is that the output signal is not present long enough or is too indistinct, so that the presence signal is not or prematurely counted out of the memory.
  • the object of the invention is to design the sensor so that the presence of the railway vehicle is reliably signaled .
  • the deletion of the presence signal is not made dependent on the course of the output signal from the sensor. Rather, the deletion takes place after a certain time, which is predetermined for the circuit by a memory or computer contained therein and which is adapted to the speed of the railway vehicle.
  • This solution has the advantage that repeated swelling and decaying of the output signal, which can occur in particular at high speeds and at the end of the crossing of the wheel, has no effect on the generation of the presence signal.
  • by adapting the presence signal to the speed of the vehicle it is ensured that the presence signal always covers a certain travel distance of the wheel or vehicle that is independent of its speed.
  • the switching signal does not depend on the speed of the railway vehicle with regard to the reliability of its evaluation. At slow speeds, it can be expected that a wheel will stop on the sensor and reverse its direction of travel. In this case, the absence of the wheel would be incorrectly signaled after the predetermined time. In the development according to claim 2, this is avoided.
  • the presence signal is deleted here when the output signal falls below a predefined threshold value and the switching signal thus drops, provided the previously determined speed of the rail vehicle falls below a predefined value. If such sensors are used to secure level crossings or switches, this speed could be around 60 km / h.
  • the circuit according to claim 3 has the advantage that the presence of the wheel or Vehicle before the final generation of the warning signal or presence signal can still be verified by a second measurement. Doing so can delay result from the fact that the switching signal of the first sensor by the Switch signal of a second sensor following in the route is confirmed. Hereby the deceleration automatically becomes that of the speed of the railway vehicle customized.
  • the speed can be determined by special sensors.
  • the Sensor arrangement double rail switch according to claim 4 has the advantage that from the sequence of their output signals in addition to the speed also the Lets determine the direction of travel of the wheel being driven over This allows the positive or negative evaluation of the counting pulses can be influenced.
