Definitions

  • the invention relates to a level crossing safety system with a level crossing controller for controlling any safety devices and a method for controlling such a level crossing safety system.

  • the United S ⁇ supply of Gleisstrom Vietnamese- and wheel sensor control also enables cost-effective design of crossing protection systems both in AREMA markets and in CENELEC markets.
  • the track circuit is formed as an audio frequency track circuit with data transfer function and the wheel sensor is connected upstream in the direction of the railroad crossing, wherein the wheel sensor is connected to the transmitter of the track circuit.
  • the track circuit he ⁇ stretches it over the entire approximate range from switch-on of the safety devices to the level crossing controller. At this switch-on is the transmitter of the track circuit to which the wheel sensor is connected ⁇ .
  • the wheel sensor is mounted at a certain distance in front of the transmitter and wired up to this. In this way, the track circuit is used as a transmission medium for the signal of the wheel sensor to the level crossing controller, so that a complete wiring from the wheel sensor to the level crossing controller is unnecessary.
  • the property of the audio frequency track circuit is exploited to provide a transfer function of a few bits. After crossing the rail vehicle via the wheel sensor, this information is forwarded via the track circuit to the level crossing controller. After that it reaches
  • Rail vehicle which reports to the lane ⁇ transition controller quasi as a second channel, the assignment information.
  • the information transmission from the first channel namely that of the wheel sensor signal, is interrupted by the track circuit. If one of these two channels or the transfer function should fail, lies an error occurs and the level crossing protection system switches to the safe failure state.
  • identifier to substitution therapiesser- and velocity detection of an approaching the level crossing rail vehicle there is provided a Zeitdifferenzmes ⁇ solution between the vehicle passages more wheel sensors and / or a wheel sensor and the transmitter of the Gleisstromkrei ⁇ ses, wherein the switch-on of the securing means is dependent on the determined speed by the level crossing controller.
  • This functionality which is increasingly required by railway operators, makes it possible in some cases to considerably reduce the waiting times of road users at the level crossing.
  • the level crossing system is activated independently of the vehicle speed in a largely constant closing time before the arrival of the rail vehicle at the level crossing. This feature is known as> constant warning time ⁇ .
  • the blocking time of the level crossing is thus optimized and shortened, especially in the case of very slow rail vehicles.
  • At least one additional track circuit is provided for driving at least one track-side signal.

  • the trackside signal serves as a monitoring ⁇ signal and is only set to continue if the level crossing is secured.
  • the track circuit be ⁇ tion
  • the transmitter can be activated upon passage of a wheel sensor and deactivated upon passage of the level crossing controller.
  • the track circuit is thus activated only during the time required functionality and disabled during the rest of the time, especially in one Sleep mode switched. This results in a reduction of the decentralized energy requirement.

  • the vehicle passage of the wheel sensor 6 is first forwarded to the train ⁇ transition controller 4 as a turn-on signal.
  • the track circuit 5 functions in the formation of this first Sprinttra ⁇ supply channel only as a transmission medium. Only when the rail vehicle passes the transmitter side 8 of the DC circuit 5, the track circuit 5 is closed and generated in turn, a drive signal for the Bahnübergangscontrol ⁇ ler 4. This results in a second turn-on, which activates the level crossing controller 4 regardless of the Radsensor-turn-on.

  • This monitoring signal 13 is provided by the level crossing controller 4 only on free ride when the security devices 2, 3 of the railroad crossing 1 have shut off the road. This results in a saving in signal cabling.
  • FIG. 3 shows an embodiment with two wheel sensors 6 and 14 which are spaced apart from each other and which transmit via the track circuit transmitter 8 and the track circuit 5 timewise passage information to the level crossing controller 4.
  • This dual-wheel sensor configuration also offers increased safety of the overall system.

  • All configurations also offer the possibility of determining the speed of the rail vehicle by Time measurement from the first wheel sensor 6 to the transmitter 8 of the first track circuit 5 and / or from the other wheel sensor 14 to the first wheel sensor 6, so that the level crossing controller 4, the safety devices 2, 3 of the railroad crossing 1 can turn on speed dependent. This results in a time-optimized switch-on with a constant switch-on time and, above all, a shortening of the waiting times of the road users before the level crossing 1.
