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.
  • level crossing safety devices in particular road-side rail barriers and warning signals and sometimes also track-side signals
  • technical devices are required that recognize the approach of a rail vehicle to the level crossing.
  • Such switching means are predominantly based on wheel sensors, axle counting devices, loops or track circuits. Line cable loops and other switching devices are also used.
  • a level crossing safety system For example from the DE 30 03 253 A1 is a safety device for level crossings and from the DE 199 28 317 A1 a level crossing safety system is known.
  • radio feedback devices based on GSM-R.
  • GSM-R Global System for Mobile communications
  • the invention is based on the object of specifying a level crossing safety system and a method for controlling it, which enable a higher level of safety, with the lowest possible cabling effort being sought.
  • the object is achieved by a level crossing safety system according to claim 1.
  • the object is also achieved by a method according to claim 5, in which it is provided that at least one track circuit and at least one wheel sensor switch on the level crossing controller independently of one another.
  • the occupancy information of the track circuit and the crossing of the wheel sensor are used as two-channel, diverse information to activate the level crossing safety system.
  • the diverse sources guarantee the independence of the control signals, while at the same time mutual error disclosure is made possible.
  • the dual-channel system using the wheel sensor and track circuit results in high availability of the overall system and the attainability of a safety level of SIL3 or SIL4.
  • the combination of track circuit and wheel sensor control also enables a cost-efficient conception of level crossing safety systems in both AREMA and CENELEC markets.
  • the track circuit is designed as an audio frequency track circuit with data transmission function and that the wheel sensor is connected upstream of the DC circuit in the direction of the level crossing, the wheel sensor being connected to the transmitter of the track circuit.
  • the track circuit extends over the entire approach area from the switch-on point of the safety devices to the level crossing controller.
  • the transmitter of the track circuit to which the wheel sensor is connected is located at this switch-on point.
  • the wheel sensor is mounted a certain distance in front of the transmitter and wired up to it. In this way, the track circuit is used as a transmission medium for the signal from the wheel sensor to the level crossing controller, so that complete cabling from the wheel sensor to the level crossing controller is unnecessary.
  • the property of the audio frequency track circuit is used to be able to offer a transfer function of a few bits.
  • this information is forwarded to the level crossing controller via the track circuit.
  • the rail vehicle then reaches the track circuit, which, as it were, reports the occupancy information to the level crossing controller as a second channel.
  • the information transmission from the first channel namely that of the wheel sensor signal, is interrupted by the track circuit. If either of those two If channels or the transmission function should fail, there is an error and the level crossing protection system changes to the safe failure state.
  • a time difference measurement between the vehicle passages of several wheel sensors and / or a wheel sensor and the transmitter of the track circuit is provided for the direction of travel and speed determination of a rail vehicle approaching the level crossing, the switch-on point of the safety devices by the level crossing controller being dependent on the determined speed is.
  • This functionality which is increasingly required by railway operators, enables a sometimes considerable reduction in the waiting times of road users at the level crossing.
  • the level crossing safety system is activated independently of the vehicle speed in a largely constant closing time before the rail vehicle arrives at the level crossing. This function 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 controlling at least one track-side signal.
  • This special track circuit provides data transmission in the opposite direction, i.e. from the level crossing controller to the signal.
  • the trackside signal serves as a monitoring signal and is only set to continue travel when the level crossing is secured.
  • the track circuit or its transmitter can be activated when a wheel sensor is passed and can be deactivated when the level crossing controller is passed.
  • the track circuit is thus only activated during the required functionality and deactivated during the rest of the time, in particular in one Switched to sleep mode. This results in a reduction in the decentralized energy requirement.
  • FIG. 1 illustrates the essential components of a basic configuration of the claimed level crossing protection system.
  • the level crossing 1 is secured on both sides by barriers 2 and warning signals 3.
  • the safety devices 2, 3 are controlled by a level crossing controller 4 for this purpose.
  • the input information from the level crossing controller 4, namely whether a rail vehicle is approaching the level crossing 1, is generated by an audio frequency track circuit 5 and by a wheel sensor 6.
  • the wheel sensor 6 is connected upstream of the track circuit 5 in the direction of the level crossing 1, so that the wheel sensor 6 is passed by a rail vehicle approaching the level crossing 1 in front of the track circuit 5.
  • the wheel sensor is connected to a transmitter 8 of the track circuit 5 via a signal line 7.
  • the track circuit 5 is directly connected to the level crossing controller 4.
  • the vehicle passage of the wheel sensor 6 is first passed on to the level crossing controller 4 as a switch-on signal.
  • the track circuit 5 only functions as a transmission medium to form this first transmission channel. Only when the rail vehicle passes the transmitter side 8 of the direct current circuit 5, the track circuit 5 is closed and generated in turn a control signal for the level crossing controller 4. This results in a second switch-on signal which activates the level crossing controller 4 independently of the wheel sensor switch-on signal.
  • the edge sensor signal is preferably interrupted.
  • the two-channel control of the level crossing controller 4 enables a very high level of security to be achieved, whereby the two independent switch-on signals can mutually check their functionality and activate a fail-safe state of the level crossing security system in the event of a fault.
  • the error disclosure required for a safety verification according to CENELEC is guaranteed during operation.
  • FIG. 2 shows an extension of the basic configuration according to Figure 1 .
  • a further audio frequency track circuit 10 is provided, which is connected on the transmitter side 11 to the level crossing controller 4 and on the receiver side 12 to a track-side signal 13.
  • This monitoring signal 13 is only set to free travel by the level crossing controller 4 when the safety devices 2, 3 of the level crossing 1 have blocked off road traffic. This results in a saving in signal cabling.
  • FIG. 3 shows an embodiment with two spaced apart wheel sensors 6 and 14, both of which forward crossing information to the level crossing controller 4 one after the other via the track circuit transmitter 8 and the track circuit 5.
  • This twin wheel sensor configuration also offers increased security for the overall system.
  • the embodiments according to Figure 2 and Figure 3 can be combined with one another, with additional track circuits and / or wheel sensors being able to be included.
  • All configurations also offer the option of determining the speed of the rail vehicle by measuring the travel time from the first wheel sensor 6 to the transmitter 8 of the first track circuit 5 and / or from the further wheel sensor 14 to the first wheel sensor 6, so that the level crossing controller 4 can switch on the safety devices 2, 3 of the level crossing 1 depending on the speed. This results in a time-optimal switch-on with a constant switch-on time and, above all, a reduction in the waiting times of road users in front of the level crossing 1.
